almost 1000 comments suggests that this is very popular. doing this monthly would really help, although people may want to repost, so maybe some rule is needed for that. probably marking a post as "REPOST" or "NEW" would help regular readers find new projects.

hollerith• 2 years ago

Adding "REPOST" or "NEW" does nothing to ameliorate the problem of the same comment occurring over and over in search results (particularly hn.algolia.com/?sort=byDate searches).

On the other hand, if each repost consists of just a link to the original post, or a link plus a few words, that would prevent the unpleasantness in search results.

I am trying to get better at trading so I thought it would be nice chance to work on my coding skills. I wondered if financial indicators actually makes money for a given period.

Made it with React, Vite, firebase via Typescript. It’s a really different world for sure.

I’m back to working on an ML app pair (train/consume) for Mac/iOS, for finding a certain type of resource.

I tried it a while back, and wasn’t too thrilled with the way Apple has structured their ML stuff (they basically only afford very specific applications, which didn’t match my workflow).

It was suggested that I revisit it, so I am.

Building more Amazon scraper websites. Working on a framework to minimize the effort of creating them, and currently testing to see if I can automate most of the process with Anthropic’s Sonnet.

The most recent site is https://computerdisplayprices.com

When I’m done, I’m probably going to make a blog post or two just talking through the automation I figured out so far. LLMs are amazing force multipliers.

frankacter• 2 years ago

what toolset do you use for scraping? puppeteer?

generalizations2• 2 years ago

Nope, just selenium and pyautogui. The priority is to fly under the radar, rather than efficiency; for that I needed lower-level control. There's a bunch of other stuff I did to improve the anonymity, but to download I just open selenium at the url, wait for it to load, then use pyautogui to type 'ctrl-s' and type in the save directory.

working on a website showing people how micropayments could work today

is_true3• 2 years ago

can you share it? or at least what you know about the topic.

fragmede5• 2 years ago

I'll share it when I've made something worth sharing :)

It'd be a basic guide that says do a,b,c,d,e,f,g to give me 10 cents, where a-g is

a) create a Coinbase account

b) fund it

c) buy some crypto

d) install a wallet

e) move the crypto to the wallet

f) connect the wallet to my website,

g) send 10 cents my way

it's not going to offer any choices of crypto and wallet, just a proof of concept to document that the rails do exist today.

mindcrime5• 2 years ago

Right now I'm mostly thinking about AI. Right this minute I'm sitting in a cafe reading a book on Multi-Agent Oriented Programming with a framework called JaCaMo[1], and later tonight when I get home I'll probably spend some time getting my Fuseki[2] server loaded with some base schemas (SKOS, FOAF, etc) as I slowly start working on getting things set up to explore some ideas around integrating symbolic logic with LLM's.

And I took my new quadcopter drone out and did some flying last night for the first time. As in, my first time flying a drone, ever. The results were... predictable. Let's just say, I bought a cheap (< $100) drone for a reason. This thing will wind up destroyed. In less than an hour I managed to crash it into fences, walls, bushes, cars, dumpsters, the ground, an armadillo, Elvis Presley, a 1974 AMC Gremlin, and Nickelback. Well, more or less.

It brought to mind this famous scene[3] from the movie Days of Thunder:

Harry: I want you to go back out on that track and hit the pace car.

Cole: Hit the pace car?

Harry: Hit the pace car!

Cole: What for?

Harry: Because you hit every other god-damned thing out there and I want you to be perfect.

team_dale• 2 years ago

lol'd at the 1974 AMC,

As an experienced drone pilot - if you can, DJI is unbelievable at stopping you from crashing. Start there to get the feel of it (and more importantly not get frustrated and give up)

If you want to learn more freestyle without assistance, i can't recommend enough getting a simulator on your computer and crashing a digital drone a million times first. It's much cheaper. I think there is a lot out there now but i used Liftoff for many hours before i tried to fly a proper drone

codazoda3• 2 years ago

I was wondering. I have a DJI and it is stupid simple to fly. I’ve yet to crash mine but I don’t fly it a ton. I’m certainly not trying to fly it through complex paths like an open doorway and into a house or something.

mindcrime5• 2 years ago

Yeah, I'm flying a super basic drone with none of the built-in crash avoidance / navigation / etc. stuff for now. I'll upgrade to something fancier later, but for now I'm totally satisfied with something I can crash repeatedly and when it breaks, throw it away (or salvage parts from it to build another drone).

I'll look into the simulator thing. I didn't even realize that drone simulators were a "thing" so I had not gone looking for anything like that.

I’m working on a screen play called DRONE RACER about kids who race human sized quadcopters through the subways of NYC. It’s a mix of Hackers and Fast & The Furious.

If HN supported images in replies, I'd totally be posting that "shut up and take my money" meme right now. As it is, I'll just say "that sounds awesome, and I hope it sees the light of day eventually."

Bognar• 2 years ago

I would highly recommend getting a drone simulator off Steam. You can practice the controls and drill them into your fingertips during times when you can't fly the real thing (battery recharging, night time, weather, ...). Most advanced radios allow you to hook them up to the computer so you can fly with the exact same inputs, but a console controller is also acceptable.

A feature-rich, nice looking audio player for those who don't stream music: https://sakunlabs.com/muziqi

It has 90% of the features that I wanted, and now I am working on what my users want.

skeuomorphism• 2 years ago

Was hoping this was for desktop, as ive been using winamp for roughly 10 years since it has everything i want, including android management support.

Regardless, keep up the good work!

em-bee12• 2 years ago

my list of features needed for a usable audio player:

for audiobooks the ability to skip forward and backwards a few seconds. the best way to do that i found is to swipe left and right. short swipe is a short skip, swipe across the whole screen is maybe a minute. also the ability to quickly jump to a certain manually chosen timestamp.

also for audiobooks, the ability to bookmark positions. not all audio books have chapter markers.

for audiobooks and podcasts: list files by their names in storage sorted by timestamp or name. many podcasts and chapterized audiobooks don't set chapter or episode titles correctly. i have seen players where the title was always the title of the book or the name of the podcast, making it impossible to identify which file was which episode or chapter. also author names and even podcast titles are sometimes inconsistent, because spelling errors, different authors or multiple names for a podcast.

do not assume that the file metadata is consistent or correct and make it easy for the user to work around inconsistencies.

sawaali2• 2 years ago

I think Muziqi ought to satisfy most of these for audiobooks. Podcasts is on the list.

skybrian• 2 years ago

I'm writing a new property-testing library for TypeScript. [1]

I wanted a way to define new Arbitraries that's easier than working with .map(), .chain(), .oneOf(), and other combinators that require you to think in terms of sets. It has those combinators, but you can also write code to randomly generate one value at a time. It uses an approach to shrinking that's inspired by Hypothesis.

Along the way, I ended up adding a Domain subclass, which also does validation like Zod. Not sure where I'm going with that, but it's also useful for generating unique keys.

(The documentation isn't done and doesn't explain what's interesting about it. Caveat: it's Deno-only, and will probably stay that way unless someone wants to help.)

kredd3• 2 years ago

I had this realization that, sometimes, people on my team are doing the same tasks in different ways, resulting each of them taking different amount of time. In certain scenarios, there is an optimal way of doing things, and I don't even know about it. Trying to test out if current AI-models are solid enough to do comparisons from a screen recording, or just general suggestions for improving white-collar workflows. I could see an eventual platform that could be built out of it.

flir2• 2 years ago

Is it possible that you're describing design patterns here?

kredd3• 2 years ago

Hm, if you mean software design patterns, then not exactly. It's probably harder to detect in just coding world, but the easiest one I can think of in our realm "checking current CPU usage of X service". In my current company, there are quite a few ways - logging into AWS -> switching to production environment -> going to ECS -> Looking up the service -> Clicking on metrics, or opening DataDog -> Dashboards -> Service Name.

I understand it's very reductive and simplified, but for every task there are alternative ways to reach the goal, and from my historical experience, everyone does everything differently. Some things can be optimized significantly, if others just knew about the possibilities.

doomroot• 2 years ago

It's possible they aren't talking about code at all.

"This team member, and this other team member are both filing a particular kind of report but are doing so in very different ways, is one of them more effecient?"

A new CI/CD platform. Local CLI (run without git push), remote debugger, automatic content-based caching, DAG-based definition, and dynamic tasks. It’s taken a lot of work to build it, but I’m really excited about how well it’s working. https://rwx.com/mint

Bnjoroge2• 2 years ago

how does it compare with dagger?

Mavvie• 2 years ago

I haven't tried this yet, but I wanted to say I think there's a lot of potential in this space. There's so much friction with the current popular solutions...and yet it's so hard to justify trying some of the newer and less popular ones.

I wish you luck because there are a lot of good ideas in here. Running locally and remote debugger are the most exciting to me.

amir734jj• 2 years ago

I like the idea, but I have used Azure Pipelines, and the key differentiating it from GitLab.ci is its "service connection" that enables seamless integration with third-party services and a wide range of tasks (PowerShell, pscore, az, docker, etc).

I wish your dependency semantics yaml could be converted to Azure pipeline task, job, and stage similar to how typescript converts to javascript.

I am saying this because there are very complicated infrastructural problems that hundreds of people work on at big companies when creating a ci/cd I see you are not focusing on them yet but that DAG logic could be applied to existing azure pipeline yaml.

rtpg• 2 years ago

This seems really neat! I'm a huge proponent of incremental CI for any project that gets big enough to care about test speed.

I'd be pretty worried about an abstraction ceiling on the caching here relative to something like Bazel, though. Like would Mint get mad if I generated 4000 dynamic tasks?

zamalek3• 2 years ago

I love Captain! I would have been over the moon to see this project ~1 year ago when I was porting our CI away from Circle CI.

is_true3• 2 years ago

what do you think about rapidapi?

I think the biggest issue is that when an user makes a chargeback they don't pay you. Which makes the 20% cut they take a bit too much in my opinion.

Also the marketplace is getting full of people abusing free APIs for money.

rogutkuba3• 2 years ago

Well I am not a fan of RapidAPI for a couple reasons, firstly them taking such a big cut of an API provider's business and secondly their marketplace feels kinda spammy and low quality.

I am trying to build so that there is little vendor lock-in (you can export your users to other auth providers, billing is integrated directly into your stripe account, etc) so that you still have the choice to migrate if you ever feel unhappy with the service

Outside of tech, I do quite a bit of "long" distance running, swimming and e-biking.

When out on a run, it leaves lot of time available for listening on podcasts, mainly technical podcasts.

At the same time, when exercising, I want to publish tidbits I've learned, do projects with raspberry pies, arduinos, make statistics over time series (power consumption, electricity price, internet usage++).

When I'm home, I'm thinking I'll do it later :).

What I'm most curious about, is how people, and I, can stay organized. All information feels like a mess :)

ubavic• 2 years ago

I am currently working on a custom markup language called atex. It's syntax reminds of latex syntax, but with @ instead \ as a special character (very similar to the Lout language, if anyone remembers it). Also, the atex language hasn't any predefined commands. Instead, all commands are defined via schema specified in a separate YAML file. Schema defines commands that can be used and means of "rendering" those commands to different targets (HTML, Tex, Typst, whatever...)

Just today, I finished first working version of the new compiler (https://github.com/ubavic/mint). It is written in Go, and there are lot of things on the TODO list, but it works :)

This is actually the second compiler for the atex. The first one was written in Haskell and compiled fixed document schema. I used it for writing a book on Haskell (https://github.com/ubavic/programming-in-haskell).

I'm taking inspiration from Lichess, having enjoyed playing chess there for years. Check out the server, client and backgammon AI I'm working on at https://bgammon.org

I recently created a custom 220gsm pre-washed cotton fabric by twisting thrice a 60s yarn (60/3 Ne) into 20s before knitting. It could never be commercially viable so released something similar.

Essentially combining the softness of fine count cotton with the weight and durability of a heavier garment.

Also a lot of ERP, warehouse, UI work and fun with Cursor.

peterldowns5• 2 years ago

I've bought a lot of different T-shirts and I'm always interested in trying to find a better (more durable; more fashionable; more comfortable) one. My current favorites are the Buck Mason Field Spec t-shirts https://www.buckmason.com/collections/mens-tees — could you explain how your shirts might compare? I'm willing to buy one just to try it out, but since you're the owner, figure I might as well ask you for more information — especially why you created a custom cotton fabric.

One thing I like a lot about Buck Mason is that their T-shirts are made in America from American-grown cotton, are any of your T-shirts made in America?

EDIT: just ordered a variety of your shirts, looking forward to trying them out. Very easy checkout experience!

sukh3• 2 years ago

Thanks for the order!

Buck Mason makes great tees. Our flagship tees use 100% American-grown Supima Cotton and are similar in weight to their classic Pima ones.

The Heavy Crew is closer to their Field Tee— ours is likely not as heavy but softer and more durable due to twisting two fine cotton yarns into one before knitting. They’re made in our own facility in Southern India.

I’ve been refining our fabrics for nearly ten years to get the best fit and feel, sticking with cotton for its comfort. More on our fabrics here: https://www.marchtee.com/us/difference

Thanks for commenting on the checkout! We’re gradually rolling out stateside, so any feedback is welcome—just reply to the order email anytime.

teleforce2• 2 years ago

Great work, for some unknown reason I cannot bear wearing non-cotton shirt and cloth, but cotton based clothing is far from durable. The best cotton shirt that I ever had until now (in terms of wearability and durability) is a mecerized golf cotton shirt by PGA Tour (casual wear not for golfing) but now I cannot find any golf shirt (PT included) with the same material anymore. As far as I'm concerned you have got a winner there mate if your cotton shirt is as good if not better than the PT shirt, hopefully your clothing materials will be available globally off-the-shelf.

Do you mind explaining your sentence here?

It could never be commercially viable so released something similar.

sukh3• 2 years ago

We do mercerize some of our products, though it’s more costly with regulated heat. If you're near an M&S, they carry a mercerized Polo, but I find it too crispy.

It could never be commercially viable, so released something similar.

Apparel is about scale. You can make a great tee, but fewer people will pay $100 versus $30, so finding a balance is necessary. Cotton can age well, but the trade-offs (fiber blends, uneven yarn, spirality resistance, no ribbed neck) often show in tees under $50.

I’m a tech nerd rare coin & currency dealer! I took my two hobbies and combined them into a real business and I’m having the time of my life. Just launched a proper retail site here:

https://www.rarity7.com/

About 50% of my days are spend doing the coin dealer stuff - hunting for inventory, buying collections/doing appraisals, going to coin shows and buying and selling in person, etc.

The other 50% I’m writing code and building out the tech stack for this business. I’ve written the whole backend for the retail site myself, which includes my own inventory management system, sync with eBay and other marketplaces, etc.

I’ve also built out a research tool which includes an ML price prediction engine engine (which sounds fancy but is really just a tabular regression model).

Backend is written in Crystal because I love the language and there’s nobody stopping me from using it :) Frontend is all Svelte and they’re glued together using a mini framework I wrote:

https://github.com/noahlh/celestite

I probably have 5 years worth of ideas I still want to build and I wish I could spend even more time building it all, but it’s super fun actually using it in the real live marketplace so I’d never give that up.

Happy to chat about this stuff with anyone who’s interested or vaguely interested in numismatics.

peterldowns5• 2 years ago

This is great, my brother is a history buff and a few years ago I bought him a Hadrian coin for his birthday. I'll look through this and see if I can find something else he'd be interested in, holidays are coming up and I'm always looking for nice gifts.

EDIT: is there any way I could set up an alert for when you add some non-US currency into stock?

nlh10• 2 years ago

That's awesome and a very thoughtful gift for him! Yes I'm planning on building alerting - BUT - I'm probably not going to expand beyond US-based stuff for the foreseeable future. It's just the niche I know and even though there's a big wide world out there, I haven't spun up my brain to learn about it all yet.

If there's any country in particular you're looking for, shoot me an email. I know a ton of other dealers in the business and I'd be happy to point you to someone who might have something he'd enjoy.

theogravity• 2 years ago

That's neat and congrats! How long does it take to be part of the authorized dealers listed on the site?

nlh10• 2 years ago

I did it all in about 2-3 years. I was a big collector as a kid but didn't get back into it in a serious way until 2021. Becoming an authorized dealer is basically, fundamentally about building trust. The whole coin industry operates in a very old-school relationship-based trusted way. To become a member of most professional orgs or become an authorized dealer, you need to have 5-10 VERY solid references from other members or authorized dealers, and the only way to get those references is to be a part of the community, build trust, and build relationships by doing business with others (which means honoring your commitments and your word and writing good checks, etc.). In the end, you need to ask 5-10 people to personally vouch for you, so they'd better know you and actually trust you.

spirobelv22• 2 years ago

Loughla3• 2 years ago

So let's say I have a few hundred silver dollars. Is this a tool to help me sort them, or does such a tool exist? Like take a picture and it identifies it, looks for common errors, and provides a base price estimate?

nlh10• 2 years ago

There really should be, but the fact is there isn't a tool that does this yet. It would not be deeply hard to build, but it would mean training a model which means getting good enough training data which means taking the time to actually do it. It hasn't been done because it requires someone who is deeply knowledgable about coins AND someone who knows how to train a model and build an app, and the fact is that intersection is pretty small (it's me and probably 20 other people? Give or take). This is very much on my long-term roadmap.

In the short term, the easiest way is to find someone who does this (eg me) and just email me some pictures. I'd be happy to tell you if you've got anything good. The old school neural net between my ears can assist.

(See profile for email).

efishnc• 2 years ago

Very cool and super clean website! Talk about your infra please!

nlh10• 2 years ago

Thanks!!

Infra: I was hosted on Google Cloud for a while -- literally a single VM running Docker Compose, but I decided I wanted something a bit more flexible and interesting, so last month I switched everything over to Fly.io and I am incredibly happy with them. It's just so easy and fun to manage.

The retail site (rarity7.com) is just a small VM running a Crystal server process to handle web requests. Image hosting is all done on Cloudinary. My backend / inventory management / trading + research engine is a separate Crystal process in a separate VM. Both connect to a Fly Postgres DB. There's one other service which is a small python process on another VM which is doing inference on my regression model. That's super lightweight and I don't need any GPUs to do the inference (tabular data is nice like that).

Overall it's really nothing fancy and it works quite well. A few web-serving VMs and an inference service for my pricing model. I train/retrain the model a few times a year on a local box (my repurposed gaming rig running a 2080Ti).

reassess_blind• 2 years ago

I have a question - I've seen TikToks of people who buy rolls of coins from the bank and sort through them for rare imperfections then sell them on eBay. I've always wondered whether it would be possible to develop an automated system where a camera takes high res photos of the coins on a conveyor belt, compares to a DB of known imperfections and sets them aside?

Is anyone doing this? It's an interesting business model as the product is money so you'd only stand to make a profit never a loss.

nlh10• 2 years ago

Nobody that I know of is doing this, and see no reason why it wouldn't be possible from a technical standpoint. I think the only reason I can imagine NOT to do is that the ROI probably isn't that high in reality. Now, granted, I don't watch the coin TikToks because 95% of it is clickbait, exaggerate, etc. But my actual impression is that there simply isn't that much actually-valuable material out there hiding in bank rolls (despite what TikTok says).

Most of the people I know who do bank roll hunting and doing it because it's just kinda fun and there's a thrill when you find a silver quarter from 1964 (worth about $5) hiding in a roll of otherwise-normal quarters. But so much of the good stuff has already been plucked from circulation.

Having said that, nothing should stop a good hacker from doing something just for the hell of it :)

fsckboy• 2 years ago

do you know why vendors take credit cards, square and applepay, even though those services charge several percent fees? part of it is for convenience for the customer, but another part is that shuttling cash around to the bank and back is time consuming, risky, and takes you away from running your business (let's say you are a breakfast place, you don't make your own cups and napkins or farm your own eggs and coffee either)

product is money so you'd only stand to make a profit never a loss

you're grabbing the expense part of the business that everybody else is trying to shed. Let's talk also about time value of money. All the money that you've invested in cash is not making money passively as other investments do. Compared to putting the money in the stock market, you're losing 7% a year on this scheme, plus the expenses of running your business, and opportunity cost of not doing something else that generates income.

s0rce2• 2 years ago

I did this for personal collections a while back and went through a lot of Canadian quarters to get one from each year and never even found the 1991 I was looking for which is somewhat rare. I guess if you do it full time or automate a bunch maybe you could make money, seems hard though.

wyclif3• 2 years ago

Cool project! I showed this to my 13 year old son who is a coin and bill collector; he loves it.

Tell your son to join the Instagram coin community if he hasn't done it already - there are tons of kids & adults on there and it's a real community that meets up regularly at coin shows, etc. Send me an email and I can give you a heads-up on some starter accounts to follow and get involved.

samstave8• 2 years ago

That is beautiful!.

One of my favorite design elements is the Guilloche patterning on currency, along with the history behind the use of Guilloche as a form of anti-counterfeiting.

Your site is very simply visually appealing.

Also - I like to order $2 bills from the bank. You can order then, mine delivers them on tuesdays - and they give you a stack of brand new $2 sequentially serialized bills. They are great for tips and gifts.

nlh10• 2 years ago

100% agree! I often get folks asking if their $2 are valuable, and tell them exactly what you do -- no, alas, they're not worth more than $2, but they are super fun to leave as tips because people still get a kick out of 'em.

pajeets3• 2 years ago

Are 1987 loonies rare?

profsummergig2• 2 years ago

Am curious how you handle trust.

E.g. someone says the delivery didn't come through. Or that the coin is not authentic.

Those are some expensive coins! So was curious.

nlh10• 2 years ago

Great question. Authenticity is easy - I mostly deal with certified coins, which means they’ve all been authenticated and guaranteed by a 3rd party service which stands behind their mark (they will pay you for the coin if they make a mistake, which does happen).

For shipping, that’s just pretty standard across most industries - I have shipping insurance and if USPS fails, they’ll pay for it. But losses happen and it’s just a matter of business (thankfully they’re rare).

One of the quite astounding things about gnuplot is that it continues to make steady progress, decade after decade, not stagnating or flaming out, without massive attention or lots of institutional support, and with great backwards compatibility.

A database for my digital life. A place where to store semi-structured data and blobs, everything from phone numbers to my browser history, mail to photo and yes, also notes with a tagging system.

The primary feature that I'm implementing p2p synchronization (similar to syncthing, although the prototype use tailscale); append-only storage for easy backup and an "api" for easy integration/synchronization with external sources like RSS feed for example, all working offline.

Right now I'm using various software to manage my digital life (Zotero, Keepass, Syncthing) but i want to consolidate since I'm having trouble keeping all properly synced and backed)

kinow4• 2 years ago

I just aggregate everything on Git and found that it works so far. Although some listings (short stories, movies) are growing a bit too much for simple files. What's the lowest level database/filesystem you have to store your data?

hexmiles3• 2 years ago

Not sure if I did understood the question correctly: currently use a sqlite database as a backend for storing data, since it make easy to iterate and inspect while I'm developing, also sqlite seem to be able to handle blob just fine (up to 50MB).

I'm planning to have pluggable backends but the primary one will be a append-only log structure within a single file, however it should be relatively easy to add a git based backend. The reason for using a custom file format is that i want add support for a couple of feature to make it easier to recover data in case of corruption of both the data and the filesystem that host the file.

peterldowns5• 2 years ago

I'm working on Devlog — https://dev.log.xyz — software that I hope will help teams work better by making it more obvious who is doing what. It should help answer questions like "what did Sarah do last week?" or "who worked on frontend performance in the last year?" It's very much in alpha-stage, more a tech demo than a product, and I'm not sure if it will actually succeed. My cofounder just bailed on me but I'm going to keep trying to make it happen. Dogfooding it has made me a better engineer — I write better and clearer PRs — and as a former Senior Engineering Manager, I know it would save me time if I were still managing a larger team. But the setup is onerous (you have to connect your Github so it can analyze your PRs) and the value prop is more vitamin than painkiller unless your team is somewhat disfunctional, and no one likes to admit their team is disfunctional.

Happy to talk more about this with anyone. If you're at all interested in "software to make your team run better" I'd really love to hear what you're having trouble with and how your team runs, maybe I can figure out a way to help you, even if it's not at all related to what I've built already.

cdfuller5• 2 years ago

Does it only work on PRs, or does it look at git history as well? Do you have plans to expand the knowledge it has access to?

peterldowns5• 2 years ago

Right now it only looks at Github PRs, particularly the descriptions and titles (although I'm also experimenting with the code diff itself), for these reasons:

- Most teams that I'd sell to use Github PRs to write code.

- Looking at PRs, the "common unit of change" of most teams, lets Devlog work for teams regardless of how they end up merging in changes (merge commits vs squash vs rebase... doesn't matter because the PR is what is reviewed and submitted)

- I believe that part of being a great engineer is learning how to describe (a) what your code does, (b) why you're making the change, and the PR title+description is where we as an industry expect you to communicate this information.

- A commit history filled with great PR titles+descriptions is extremely valuable for your team and only becomes more valuable over time, so building tools that analyze this and incentivize you to do a better job of writing good titles+descriptions is good for your whole team.

I'm extremely open to looking at different sources of information (Linear/Jira/Github tickets; the diff itself; ???) if it improves the product. What were you thinking it should look at?

ecuaflo6• 2 years ago

Read-only makes it so a buyer can’t push to main or modify the repo configuration. So to stop someone from paying to “grief” it in the worst case, and just to stop buyers from making changes the owner didn’t sign off on in more typical cases. They can still raise issues and submit PRs, to my knowledge.

Some of the machines he's repairing cost upwards of $40,000 so i'm not sure it's a price thing.

Right now I have ALMOST 10k user installs. It's called Gemini Sidepanel [1] if you're interested in checking it out.

A firewall for SMS.

Scams usually start with messages. Predominantly SMS/email sent with links.

ML models exist to determine this, but we are prototyping using Gemma2 2b to utilise its natural language understanding to see if a better firewall could be built, one which users can talk to.

It has been surprisingly easy to get started on this project: https://ai.google.dev/edge/mediapipe/solutions/genai/llm_inf...

We want to subsequently build a firewall for Calls, too; but that's a more challenging problem given its dynamic and online / realtime nature.

Hope to integrate these two features in our existing network firewall open source app.

I’m building a door. I find that mortises (my frame is mortise and tenon, the tenons were easy on a table saw) are much harder to create if you don’t have a proper plunge router. I’m using some chisels and it works fine but I have eight mortises to make and I’ve finished 1.5 in about the same number of hours. I don’t want to buy a plunge router, because I’m unemployed at the moment, but it would finish the job in minutes. I guess I’ll go get to chiseling! Next door I make will use half laps, so I can use the table saw for both ends of the joinery.

Embracing the solitude and the mindset that no one is coming to save me has sparked a bunch of motivation (out of spite) to improve myself. Started to workout regularly which has been a huge help for my mind and body. Starting to peel back layers of things that happened during childhood now.

Wish you the best of luck on your journey.

Kudos to you! Even just being more aware of your mental state is a step in the right direction. Reminds me I need to be more proactive in this area.

Dunno if it helps, but just know most of us are at least a bit of a mess. Life is messy. I once took two years off of regular work (we were fortunate to have enough savings to do it) and made two music albums, the first album based exclusively on hard things that either I or people very close to me went through. The process of fleshing out the songs and lyrics was incredibly therapeutic for me.

rachofsunshine3• 2 years ago

Dunno if it helps, but just know most of us are at least a bit of a mess.

Years ago, I tried to quit my job because I was feeling terrible about how I was doing. My boss gave me one of the best pieces of advice anyone's ever given me:

"You know, Rachel, the suicide rate among founders is..."

This probably sounds like one of the most unhelpful things someone could say in that situation, but it was EXACTLY what I needed to hear. I didn't need someone to say "oh, it's ok to feel bad". I needed someone to say "feeling bad doesn't mean you're not strong enough to be great". I needed to hear that ambitious people who are trying with all their might to be better are still constantly struggling with the idea that they aren't good enough.

YC's own founder school doesn't quite put it in those terms, but there's a LOT in there about the importance of human factors. Arguably more than there is business advice, actually. They explicitly say, for example, "don't pick a co-founder who has complementary skills, pick one that won't drive you insane, because breakups and not lack of skill are a more common failure mode". And there's like half a dozen videos on how to keep it together when you're stressed beyond breaking. It's pretty reassuring.

To really make the point: my company became profitable for the first time yesterday afternoon, and I spent a good chunk of the 24 hours since then ruminating on how now we might fail because I'm not sure where the next bit of revenue comes from. Never mind that the things I was worried about one, two, three, or four months ago have all gone better than I feared - anxiety doesn't care about that. It'll just glom on to whatever excuse it can get - see e.g. https://news.ycombinator.com/item?id=40191179

freshpots• 2 years ago

Sometimes things click and sometimes they don't. Like when someone tells you not to worry about the things that you can't control. What worked for someone close to me was imagining and believing that everything will work out in the end. Over time they have seen the positive in life and opened more opportunities than when they were cynical.

rachofsunshine3• 2 years ago

Good for you! It really is the very most important thing, to find ways to not be at war with yourself when the world's got more than enough things for you to be at war with to begin with.

The recent relicensing of Redis to a non-open-source license bothered many in the community. But the groundwork for the relicensing was laid much earlier. I've been working on relicensing monitor to track various projects attributes that can affect the ease of relicensing a project.

https://alexsci.com/relicensing-monitor/

hypeatei2• 2 years ago

Is there a specific reason that Firefox is considered low-risk for a rug pull? In my view, Mozilla doesn't seem the same as it once was but maybe there are specific reasons the open-sourceness isn't in jeopardy.

PeeMcGee• 2 years ago

I imagine Firefox would die instantly if it moved to a restrictive license. It would be too easy to simply switch to a popular fork, and Firefox's userbase are the type that would be compelled to follow through with it. Even ignoring FOSS principles reasons, most folks are browser-savvy enough to understand the implications of such news -- their favorite browser is about to kill itself so they have to pick another one. Also consider that Firefox would no longer be the default browser in most Linux distros, and likely prohibited from official package repositories entirely.

8organicbits4• 2 years ago

Firefox scores well because it uses a copyleft license and the ability to relicense contributions remains with the original authors. Mozilla can't unilaterally relicense the Firefox code base as they haven't been granted that ability by the contributors. The copyleft license means they can't slap a new license on top (like a permissive license allows).

The rating criteria was designed to consider legal facators, like license terms and CLA, so concerns like Mozilla buying an ad company aren't factored in. Those concerns feel more subjective to me, but are certainly valid.

https://alexsci.com/relicensing-monitor/projects/firefox/

jeeyoungk2• 2 years ago

I also think CLAs are eerie and goes against the open source spirit, I don't think CLA alone puts a project in "high risk". I'm not sure about the FAANG open source projects that are used as libraries (Guava, React, ...). These projects fundamentally don't jeopardize these company's businesses, and serve to increase the developer goodwill amongst the engineers. Nobody can predict the future but I can't imagine these projects becoming relicensed.

More plausible scenario is them becoming an abandonware, but even in those cases the community can carry the torch.

8organicbits4• 2 years ago

Agreed, and there's a few projects with CLAs that are ranked lower due to mitigating factors, like K8s [1]. I honestly don't get why they have a CLA, anyone know?

The impact of developer good will is difficult to measure, so I don't attempt it. Redis burned community good will so badly with their relicensing that several forks rapidly emerged. Seemed like a predictably poor decision to me.

I also don't want to pick favorite companies, because it's subjective, companies can change strategies or even sell projects off. What if Meta decided to sell React to a patent-troll-like company instead of just abandoning it?

[1] https://alexsci.com/relicensing-monitor/projects/kubernetes/

em-bee12• 2 years ago

do you consider the likelyhood that a project will be forked?

for example react is listed as high risk, but at the same time i would consider the risk to be very low in the sense that if it is relicensed then it will be forked immediately backed by a community that is strong enough to sustain such a fork.

i'd go as far as saying that for react relicensing would kill the project because the majority of users would go with the fork.

for other projects the risk is higher because they don't have a strong FOSS userbase that could sustain a fork, and because most current users would not care.

8organicbits4• 2 years ago

What happens after the relicensing isn't measured as the community has already been disrupted. I'm also less certain on how to fairly measure and predict fork likelihood.

One challenge for forks is that relicensing doesn't always jump from fully-open to fully-closed. There's a lot of "fake open-source" and source-available licenses, like the one Redis now uses. These may "only impact you if you are AWS", so a fork "that AWS can use for free" feels less compelling. If React was to relicense, I expect they'd similarly take a small step.

Working on Pulselyre, a touch-focused Windows app for producing electronic music live. It doesn't output audio on its own, but it lets you configure various virtual "instruments" on screen that can send MIDI note and control messages to other MIDI devices or VSTs configured to receive MIDI messages. You can record notes and events for each instrument and then loop them over a configured number of beats. Also has some other features to make creating music easier, like saving/loading note sequences, an arpeggiator, receiving input from external MIDI controllers/keyboards, and some other stuff. I've been meaning to record a demo video, but I'm not actually very good at playing or making music myself, so I haven't come up with anything presentable yet. I'm also not really married to the name, but it works for now...

https://www.pulselyre.com

It's built using C# and WPF, and a related project I work on is an open source MVVM framework called UpbeatUI for making WPF apps that behave vaguely like mobile apps. It's for apps that have a main bottom layer and modal popups that float above and can be closed by clicking/touching the background. Pulselyre uses UpbeatUI, and I actually originally extracted UpbeatUI from a much older version of Pulselyre.

serial_dev2• 2 years ago

I'm a Flutter developer starting to be a bit disappointed in the tech (and the community) and sceptical if it can really produce great apps, so I'm thinking about switching to something new in the coming years.

I decided to build a multiplatform app with SwiftUI to test out the waters. So far, learning SwiftUI and building an app is somehow both easier and harder than expected, but I'm glad to see something new.

I'm planning to write a series of apps in the next 6 months, so that I build confidence shipping apps with SwiftUI and maybe find a smaller contract with it.

SupermindPT3• 2 years ago

Why are you disappointed in flutter ?

serial_dev2• 2 years ago

It's certainly not terrible, and I'll probably stick with it a year until I learn something else as well as I know Flutter...

But to answer...

Main reason, I'd like to ship software that isn't only good, but great. To create great apps, it needs to integrate into the OS/browser, and my experience with Flutter has been not great in this regard. The apps always look and feel a bit foreign. I'd rather write 3 separate apps (web, ios, android) that feel great, than ship something faster (if even...) that is so bad, sometimes I feel it's a spit in the face of our customers.

The mobile alternatives became much better: when they started, they were (as I remember) significantly better than the alternatives. Since then, RN became much better, Swift and Kotlin became mainstream, SwiftUI, Jetpack Computer came out, and in a couple of years KMP will also offer a pretty compelling alternative.

Flutter is spread too thin: I understand why they did it, it's great for marketing, and I know people who use it on web, desktop and embedded and are happy... To me, however, it feels like they added platforms before making iOS and Android work and feel great. I hate that I had to debug and pin dependencies that broke due to web incompatibility on an a mobile only app. IMO, it's so shjt on web it's laughable.

bbx2• 2 years ago

For the past year, I've been working on a CSS Masterclass: https://cssmasterclass.io/

It's going to have online text courses with interactive examples and coding exercises, but I'm also in the process of adding video tutorials. These videos will be of 2 types: ones where I teach you the theory, and ones where we actually build a project from scratch.

I feel like CSS has always been something that was made to look harder than it actually is. In its essence, the syntax is very simple, and the vocabulary is quite basic. There are only a few things you need to know to be able to code an attractive and flexible responsive web page. For comparison, I find programming backends much more difficult.

Even though I've been working on this project for almost a year, I decided that next month will be the day I finally launch it.

elric8• 2 years ago

Sounds great, I know a lot of people who could benefit from this.

I think CSS has historically been a lot harder than it was supposed to be, because browser support was shit. They were slow in adopting new CSS features, and existing features (even simple features!) weren't correctly implemented in all browsers (looking at you, Internet Explorer!).

Things are better now, for the most part, but everyone seems to have migrated to web frameworks, and writing HTML and CSS from scratch has become something of a dying skill.

Together Gift It solves the problem just the way you’d think: with AI.

Just kidding. It solves the problem by keeping everything in one place. No more group texts! You can have private or shared gift lists, and there are some AI features like gift idea collaboration and product search. But the AI stuff is still a work in progress.

I'm working on Minders [1], a journaling/notes app. I've been using it for a little over a year for daily journaling and keeping track of interesting links or ideas. It works like a Twitter feed of just your thoughts.

It's been fun to work on as I can throw in whatever neat ideas I want since I'm not trying to fit it into a neat category. For instance, I was experimenting with a multi-column browsing experience after I saw a post here [2] for inspiration. The UI could work like TweetDeck but for your notes. Not 100% sure yet if it works, but I'll be doing more prototyping.

Right now I'm revamping the sync system and other runtime parts as I'm realizing that once you start amassing lots of posts, it gets bogged down a bit. I probably could've architected some of it a bit better at the start, but I tend to try to release stuff as early as I can to force myself to ship and to see what people think.

allenu2• 2 years ago

Thanks for the interest. It's definitely not at the level of polish as Day One yet. I used to use Day One years ago when it was still a one-time purchase app, but even back then it had nice things like recording your location and local weather conditions. I'd love to add simple niceties like that eventually.

I'm trying to position my app less like a traditional journal and more of a "jot down quick thoughts" place, hence the social media-like interface. But I also want to add more zettelkasten-like features as well, so it's kind of a shoebox app for whatever you want to keep track of for later.

I was actually playing around those files today. I know this will be a typical HN comment and I'm sorry but, if it takes you an hour to load that data into sqlite, you're probably doing something very wrong.

  $ sqlite3 x.db 'create table foo(a,b,c)'

  $ time for year in {1880..2023}; do
      sqlite3 x.db '.import yob'$year'.txt foo --csv';

  user    0m1.013s
  sys     0m0.323s

  $ sqlite3 x.db 'select count(*) from foo'
  2117219

(Numbers are from Linux/tmpfs/i9-12900k)

Obviously that needs tweaked to store the year in a column, but it shouldn't run for more than a few seconds. Those csv files are the furthest thing from "big data".

Fair. I'm sure there are waaaay more efficient ways to load that into the db.

It's not like I gotta keep turning the crank.

These days, I've been working on a small tool to run GUIX as an unprivileged user, so that you can use GUIX profiles as a dev environment builder. I didn’t do any market research, but AFAIK there are similar tools using Nix. Honestly, this is just a toy project for fun. I had GUIX on one hand and Zig on the other, so I figured, why not try something new using both?

Why not Nix? I just don’t like the Nix language. Plus, it seems like they ended up reinventing part of Lisp with their Flakes, which made me even more convinced in using GUIX. The GUIX folks didn't disappoint me, as they utilized the full power of Scheme to design a (internal) DSL that is clean and almost reads like JSON/YAML. I feel quite confident that it’s a better language for building devenvs for most people. The only downside is that it can get really verbose, but, hey, at least you have full control.

majoe• 2 years ago

Plus, it seems like they ended up reinventing part of Lisp with their Flakes

Curious what you mean by that, could you elaborate? I thought nix flakes to be just a standardised attrset for inputs/outputs.

esjeon2• 2 years ago

One thing is that I was referencing the old popular quote on Lisp: "Whoever does not understand Lisp is doomed to reinvent it," so there’s a little bit of exaggeration there.

Still, it’s true that Nix Flakes is a kind of dynamically-typed environment that lets you compose various constructs in Nix in a uniform way. But, let's be honset, we have had duck typing forever, and Lisp is a dynamic language from 1960s. Reading through forum posts (as I never went deep with Flakes), Nix really needs a fundamentally better language, or I have a strong feeling that the project will just keep reinventing language features one by one.

You could even make your own app connect to your own storage and montage service, so it can be completely diy.

I want to eventually write my own virtual machine and create a functional programming language on top of it.

For the past few weeks I have been working on Enhance [0], a SaaS to help game developers easily add leaderboards, friendlists, store players' data, in-app currency store and purchases, and marketing tools such as email list and website builder and hosting.

I am almost done with the landing page and don't think I'll put much more into it, and will continue working on the API itself. But I still plan on adding a playable game into the 3D scene just for the sake of it and to learn. But so far I'm struggling at projecting a 3D camera render to a texture inside an already existing 3D context.

1. I'm writing a book on Git. I did my research and was shocked to discover many otherwise tech savvy individuals still cannot manipulate Git from the command line, and resort to the use of desktop applications (yikes!)

2. An edtech app to learn coding efficiently. AI will certainly enable 100x developers, but we must first train 1x devs.

Features: structured learning, a curriculum designed by humans, AI assistance for when stdents get stuck, code samples and project based learning, covers different languages (we start with Ruby, Rust and JS, with more to be added), and technologies (CL, Nushell, SQL - again more to be added), numerous exercises. Think of it as an improved version of w3schools and the like.

One reason I am disclosing this online is to hold myself accountable.The other is in hope of finding an angel investor.

I’m working on a collaborative ebook reading app. The idea is that you can create a reading group, invite people and then share comments and highlights and see each other’s reading progress.

It’s something I’ve been wanting for a while, for example to read a book with a group of friends or with a work team, but there’s lots of other possibilities including author reading parties, proofing and education. Got the basics of it working now, need to polish the UI and add the commenting and highlighting features.

I’m using Next.js and Supabase, neither of which I’ve used before so it’s been a fun but often frustrating process. Claude has been an amazing assistance, fixing my mistakes and countless type errors.

That’s a fascinating project, thanks for sharing. I’m using epub.js as it already has things like annotations and highlighting and it’s fairly easy to override the book styles.

Storygraph[1] does this with their Buddy Read feature. My wife and I use it to read books together and leave messages about different happenings, which only get unlocked when you mark that you've read up to that page in the book. It's a great feature, and we really enjoy it.

pmarreck2• 2 years ago

feature idea- you can see the reading progress of everyone in the group to sort of apply some passive social pressure to catch up if you're behind

then again, not everyone might be willing to do this since the book club might not all be about actually reading the book for them

Experimenting applying Meta's V-JEPA [0] architecture for representation learning to chess. One of the challenges is that validating if the model is learning useful dynamics of the game, so I'm using it as an excuse to learn some reinforcement learning by using the representations generated by the JEPA model to approximate useful Q-values [1]. This method currently has no search so I'm planning on comparing with this paper [2] which achieves GM level chess without any search. Honestly, Im unsure if the full pipeline is stable enough to even converge, but it's fun experimenting. I'm bad at chess so I really want to make a bot that challenges the best bots on lichess.

Working on generating zsh tab autocompletion for my CLI framework. I'm finding it difficult because zsh makes completion surprisingly complicated and the zsh docs have a lot more descriptions than examples. Other CLI frameworks all seem to approach this differently.

Skimming through this guide: https://dolthub.com/blog/2021-11-15-zsh-completions-with-sub... it seems to be a lot more convoluted than I thought. Really, every external CLI binary that supports completions has this autocomplete script?

I thought zsh parsed man pages to get available options/subcommands.

snowpalmer• 2 years ago

Pretty interesting take on a finance app! I like the inbox and filters on transactions. I'm not sure I understand the benefit of storing it all in the browser though. Does the data just live in the browser? Does anything store on a server?

stpn2• 2 years ago

Originally this was a privacy angle - the data is primarily stored on your device, with backend storage that’s treated like backup and sync only. I had plans for e2ee that built on this but it didn’t turn out to be a big differentiating factor.

Working in local-first turns out to be really nice for making the app feel super snappy. The responsiveness you see in the demo is the performance you can expect in day to day usage.

wecodemore• 2 years ago

That looks quite nice and the local first approach was a good idea.

I wonder how it will compare to ActualBudget and its pre/post rules and the GoCardless account data importer.

Side note: The first col of all text overlaps with some other text on mobile devices (both landscape and portrait mode) and thus is unreadable.

Also the inbox didn't work an I can't look at the inbox as the filters stay open.

Edit just noticed that this is a SaaS. If it would be a single payment for a license or sponsored FOSS, I believe it could work. The current way, I would assume that it will meet the fate of all the other apps in this non-market. Good luck though!

ianthehenry2• 2 years ago

https://bauble.studio/ is a lisp-based procedural 3D art playground that I hacked together a while ago. It's fun to play with, but it's a very limiting tool: you can do a lot to compose signed distance functions, but there's no way to control the rendering or do anything "custom" that the tool doesn't explicitly allow.

So lately I've been working on a "v2" that exposes a full superset of GLSL, so you can write arbitrary shaders -- even foregoing SDFs altogether -- in a high-level lisp language. The core "default" raymarcher is still there, but you can choose to ignore it and implement, say, volumetric rendering, while still using the provided SDF combinators if you want.

The new implementation is much more general and flexible, and it now supports things like 2D extrusions, mesh export for 3D printing, user-defined procedural noise functions... anything you can do in Shadertoy, you can now do in Bauble. One upcoming feature that I'm very excited about is custom uniforms and embedding in other webpages -- so you can write a blog post with interactive 3D visualizations, for example.

(Also as a fun coincidence: my first cast bronze Bauble arrived today! https://x.com/ianthehenry/status/1827461714524434883)

turtledragonfly2• 2 years ago

Am I right that the output of the lisp code is ultimately a plain GLSL shader (like one might find on shadertoy.com)?

I built a SDF-based rendering system (2D) for my game, and one of the big hurdles was how to have them be data-driven, rather than needing a new shader for each scene or object.

Would be curious if/how you tackled that problem (:

ianthehenry2• 2 years ago

Yep! It just outputs GLSL. It doesn't do anything smart -- it's a single giant shader that gets recompiled whenever you change anything, so it wouldn't really work for something like a game. I mean, it could handle like basic instancing of the form "union these N models, where N<256" but there's no way to change the scene graph dynamically.

jkcxn2• 2 years ago

I've done this for a project where the SDF functions are basically instructions, and you can build up instrictions on the CPU to send to the shader. and then the fragment shader runs them like a mini bytecode interpreter. You can tile up the screen to avoid having too many instructions per fragment. Kinda wild idea and performance may vary depend on what you're doing

I'm going to add a secondary high-current power distribution bus with a couple of bus-bar distribution blocks at convenient points, to make it easier to add accessories. I've already replaced one of the battery terminal screws with an aftermarket one that adds an extended stud and a nut, where you can attach a cable with a ring terminal. And I've got heavy duty copper lugs, some #2 welding cable, a hydraulic crimping tool, and the distribution blocks waiting on a shelf.

Once that's in place, It'll be very convenient for adding ham radio gear, an air compressor, a power inverter and some other things I've been chewing on.

I'm trying to make it easier for Blind people to get into electronics as a hobby. There are many fascinating hardware, software, and UX challenges here that almost nobody is working on. Things like reading circuit diagrams, identifying pins on components, debugging circuits, laying out things on a breadboard, identifying wires, identifying resistors, testing components, and much more are largely unsolved Despite all the barriers, there are some Blind people who build electronics projects, sometimes including soldering, but they usually have to develop their own tools and workflows almost from scratch.

Since I'm just one guy with 100 ideas, I have to try to apply my skills where they can have the most impact. My current project is converting existing circuits from Fritzing format (which is usually displayed graphically) into a textual format. I wrote about it in these three blog posts:

You can use a bathroom sink as a skate bowl. There are also lots of companies making fun obstacles with different materials. The possibilities are endless.

I'm working on writing a sort of code and data playground from scratch - with currently only CodeMirror, ProseMirror, and some icons as dependencies - so that everything in it can be edited live. Everything is web components with the shadow DOM. It is sandboxed both as a whole and at the notebook level. The overall sandboxing uses a Content Security Policy that allows inspecting the URL for following a link, to enable using untrusted code (from humans or an AI) and private data without it easily being leaked. I've built a resizable split view, draggable tabs with multiple panes, and a color picker. It's a few dozen Markdown files with code in fenced code blocks and a Deno and Docker-based build process. There is a hybrid notebook/playground editor with the fenced code blocks changed into links that open the files in tabs. It's open source and at https://ristretto.codeberg.page/

When the hype was focused on chatbots, I joined a startup that built one focused on ecommerce. It turned into a useful product that actually help real customers.

Looking back, there wasn't any material to actually build a useful chat agent that resolved real-world problems. So I'm writing the guide that I wish I had when getting started.

I'll publish it on github and post here as more progress is made. I've created three parts. Part One is a non dev focused which explains how each of the moving parts work, what is Ai and what isn't. Part two gets technical and explains the tech stack. Part three is a bonus section that looks at how Ai assistants like google and Siri work and can be improved.

The working title is Automated Agents.

I'm trying to make it easier to run clubs, associations & organizations with a platform called embolt.app[1].

We're offering online memberships, event management, and a member database packed with features. Membership management is a crowded space, but it's also a low-tech space with lots of sleeping giants not willing to iterate on their product.

It's been a really fun project so far and even more rewarding to see clubs using embolt for their daily operations.

Tallain3• 2 years ago

Looks very cool from what I can see. Any plans to have an open / public API? For many associations past a certain size, an integration is going to become an inevitability (syncing member lists between systems is the most common, but also events, i.e. letting people register for an event on your site and then syncing to Zoom for automatic registration and email handling).

For work I'm working on AI implementation. Because the vendor does all the technical goodness I'm kinda bored. It's also quite a crap solution IMO and we're kinda forced to be all positive about it because the vendor is closely watching and they have a lot of buyin from the top.

drusepth2• 2 years ago

I and a friend are working on Elixir Emporium [0], a single-player crafting RPG that uses layers of generative AI to create and inject new game data as you play.

It started out as just a prototype asking what happens if you task an LLM with generating crafting recipes for every combination of items in a game (which was already super fun), but it's exploded into all kinds of crafting, harvesting, and item manipulation systems that literally weren't possible in games just 5-10 years ago.

Now we're working on NPC simulations based on last year's Generative Agents: Interactive Simulacra of Human Behavior [1] paper. Dialogue and persistent memory are obvious, but we're also using the ReAct pattern [2] to give NPCs an influenceable decision loop that dictates what actions they take throughout each game day. And there's some other fun stuff like quest generation and using LLMs as a decision engine to determine if certain player actions complete these dynamic quests.

There's still a lot of work to do to make it feel more like a polished game, but we've been focused on the underlying systems and getting them feeling great and I'm really excited to see the game come to life.

devbent• 2 years ago

I'm working on something similar but instead of basing my efforts on the generator agents paper I'm basing it on a technique I call narrative generation. It requires far less context and fewer prompts, and focuses on generating narrative aspects and letting the traditional game engine things simulate the remainder of the world.

As an example, with the system I am building you only need to input what action the player has taken, and all the NPC's actions and dialogues will be generated.

germinalphrase2• 2 years ago

Making swim baits. I started carving and paints fishing lures during Covid. It’s easy to knock out something that looks like a lure, but it’s surprisingly nuanced to make something that behaves in the water as you want it to. Mass production is absolutely the correct way to go about this, but - you know - it keeps my hands busy in the evening and I’m improving my carving, airbrushing, weighting/buoyancy, etc with each one.

mindcrime5• 2 years ago

I have a ton of respect for people who can craft beautiful and functional baits. I watch Nate Marling a lot on Youtube and it amazes me what he can do with a block of wood and some wire.

Do you fish your lures, or is making them just a hobby unto itself? If the former, what species are you targeting? I consider myself a bass angler, but I honestly haven't a. had much time to fish lately or b. had much luck catching bass when I do find time to fish.

germinalphrase2• 2 years ago

I’m in Minnesota, so mainly targeting panfish, bass, and pike. Salmon when I can get away for the run. I do fish them, but I’m only now getting to the point that my crank/swim/glide baits act right. Hand carving right now, but may try to start making molds next.

Engineered Angler Lures is another YouTube creator worth checking out.

Also, I try not to be precious about them. Give them away to friends. Don’t stress if they break off. Just make another one.

I've got stuff working in Pascal[2], but that's not something most people can deal with. I've also got a ton of other stuff up on GitHub that I should poke a bit.

I've spent a lot of time in analysis paralysis and this has given me the kick in the pants to get me going again.

As far as new ideas go, I've already spent time learning Verilog, and hope to get a chip design through the TinyTapeout[3] before too long.

Also, I found out that it only takes a few lines of Python and a lot of time to have an AI rate all my photos locally. That's a work in progress, should be less than 100 lines all told with niceties.[4]

I've been working on a kind of strategy game called Fall of an Empire (https://fallofanempiregame.com), it's a bit like a mix between Crusader Kings, Total War, Mount and Blade type games (just the overworld, not the battles), but rather than expanding you're trying to prevent an empire from collapsing.

It's a ton of work, especially with the number of systems - you've got combat, resource management, settlement development, food managment, espionage, diplomacy etc - these all need to play together well. And then you've got to add in the storyline, graphics, marketing -but I think I'm making pretty good progress.

I'm still using Unreal Engine 4 because I started work on that version and I haven't needed to upgrade to 5 since it's been released. I've got a free prologue that I'm releasing on October 1, so now until then is a lot of polishing to make it work well.

Steam recently made some changes that are pushing game studios away from prologues. Instead, demos can have their own steam pages. Plus all hyperlinks will soon be banned.

I also noticed your game has been up on Steam since January 2022 and by the looks of it, you've done about zero marketing (steamdb.info). Hope that's on the horizon, it's a pretty darn important part of game development now!

Love the concept of your game. Reminds me of my favorite roman emperor: https://en.wikipedia.org/wiki/Aurelian

joegibbs6• 2 years ago

Thank you! If you replace a prologue (as standalone game) with a demo, can you transfer the wishlists?

Marketing isn’t my strong point, if I ever had the money to make another the first person I’d hire would be marketing. My boss owns a PR agency and she said she can help in getting it out to journalists but that’s about it. I tried CPC and it came in at about $1/wishlist.

Are there any methods of marketing you recommend?

They recently released Pharaoh: Dynasties which is pretty much a complete overhaul of the base Pharaoh game, and is pretty much what the game should have been.

They gave everyone half their money back, this free upgrade, new factions, bigger map and a ton of changes. Overall its been a big push from their side to keep the player base happy.

But yeah, there's obviously a big market for historical games, from city builders, combat, etc. and I'm here for them all.

grif-fin• 2 years ago

Also curious to know what's sharable under the hood. Getting good results, looks good.

hoqqanen• 2 years ago

The results of the categories look similar to what happens when prompting ChatGPT with "describe a list of {genres/moods/etc.} for <content>". Also the links are all for query pages on amazon/spotify/etc, which says LLM to me (rather than a database). This dynamic schema generation -> UI supported query builder seems like a really interesting direction. I'd love to see it for the web more generally and I bet Exa.ai+LLM of choice would be a pretty good place to start. If it's an LLM I'm curious about hallucination rates and excited for future web-level RAG in only returning real objects.

Also you can supply content which doesn't exist and it will automatically infer genre and such (another strong indication of LLM). I.e. you can imagine the aesthetics of the kind of content you might want by title and then use the UI to explore real recs related to that.

PS to the creator: I love the simplicity of the design and the execution is inspiring. Sent a dollar for my searches :-)

2143• 2 years ago

It's a very cool idea.

However, I gave it "Jane Eyre" (a mid-19th century novel by Charlotte Bronte; it's a classic) with the expectation that it will return "Wuthering Heights" – another a classic novel written in mid-19th century by Emily Bronte (yes the authors are related) – among other things. People who like Jane Eyre tend to like Wuthering Heights, and vice versa.

But everything it returned were new works – published in the last 20 years – of stories that are set in the 19th century.

The only filters applied were: "Preferred: Gothic romance novel, Victorian literature, Highly influential classic literature, Early 19th-century England ".

So, something seems amiss for now. Nevertheless, it's a very cool idea.

(Edited to fix my grammar; English is not my first language, so pardon me for any mistakes.)

kolleraa4• 2 years ago

Thanks for the feedback!

This is happening because I intentionally added a strong bias for more recent books. I thought that's what most people would be looking for - at least for fiction - and I also assumed there were other good ways to discover older books (lists, collections etc).

You're absolutely right though, it should give you some Victorian lit given your preferences! I'll work on addressing this.

emrah3• 2 years ago

This is a huge gap we have these days. Everything out there is incentivized to suggest the most selling stuff rather than unique and interesting stuff.

kolleraa4• 2 years ago

Yeah, this is definitely an important aspect of the problem I'm hoping to solve. I've found that selecting interesting preferences yields some interesting, non-obvious results "out of the box" - but if you really want to go off the beaten path try selecting the "Little known" preference under Other (and make it Required).

Lots of AI engineerers are doing vibes-based engineering, just eyeballing the LLM output and saying "LGTM!". This is a good place to start, as we all should look at our data more. But it's best to move on from vibes to system evals.

The first issue is on how to design and build system evals for a systematic way to gauge how well your LLM app is doing. That way, no matter if there are new models, new users, or new queries, you can be sure you're continuously improving, rather than allowing regressions.

You can buy the first issue here:

I'm currently working on NewsNinja[0] in my spare time, a RSS reader app that groups articles talking about the same story and optimizes reading time.

I started it a couple of months ago, I was tired of reading the same story posted across different news outlets.

Over time I added new features like summarization, the ability to hide articles that have specific words in titles, etc.

Currently working on adding custom themes and fonts for the reader mode and various customization options.

It's a fun little side project, still much to do to improve it, I'll be busy for a while!

I'm working on a news analysis project where I'll have to identify articles that speak about the same event. For now, I think it'll be based on date + "asking an LLM", but you probably came up with something better. How do you approach this problem?

ljhsiung• 2 years ago

I'd like to work on my writing skills. Some mix of nerdiness and personal Journaling. https://dynomight.net/ is a website that I'm quite inspired by, as it's a interesting mix of personal commentary (https://dynomight.net/advice/) and deep data dives into e.g. homelessness and seed oils.

My main barriers are 1) writing discipline and 2) some obsessive need to link/cite every claim I make. This results in me taking months to write an article, be it due to laziness or constant rabbitholes/google scholar searches about an idea.

Any clue on dedicated disciplined writing time or even considering "reducing" the rigor of writing?

kmoser3• 2 years ago

Over-researching is probably better than under-researching. To reduce time spent researching, try imposing a deadline. The difficulty will be sticking to it, since nobody but yourself will be breathing down your neck.

It's very early in development - you can go and just use it right now. But soon I want to support creating an account, saving / sharing shaders, and eventually go beyond the featureset of ShaderToy by allowing for custom input images / textures.

I’m working on a new game. I’ve been trying to get back to the basics of the adventure genre. A fun and engaging story, choices, strategic combat and a simple, straightforward approach.

No microtransactions, no advertisements. No networking! The game is meant to function completely off line. The game will start with a mobile release in probably October and should be available on Steam shortly after.

I’ve been using Flame, Flutter’s game engine to develop my app. My artists are amazing and have been providing fully animated sprites using Spine. I’ve used Flutter before but this is my first time getting into Flame.

If you’re curious how it’s going, hop on the mailing list at https://danger.world to learn more. I’ll be looking for my initial playtesters here in the next few weeks.

This is really neat, have you had any issues with hallucination?

cl422• 2 years ago

Thanks for asking! Yes, but we're actively addressing them.

We do a few things under the hood to make hallucinations significantly less likely. First, we make sure every single statement made by the LLM has a fact ID associated with it... Then we've fine-tuned "verification" LLMs that review all statements to make sure that assertions being made are backed up by facts, and that the facts are actually aligned with the assertion.

It's still possible for the LLM to hallucinate in this process, but the likelihood is much lower.

rachofsunshine3• 2 years ago

If you're doing this as a business, you should consider how you think this is different from e.g. Figma (for designers/PMs) or Framer (for design-implemented-as-actual-usable-component-on-a-low-code-site). What you're describing sounds very similar to Figma's developer mode, at least framed the way you frame it here. Is the idea that, say, the design files are loaded as CSS or React components or whatever directly into your site, rather than being copied or imported?

(If this is just a personal project, disregard! But "quit my job" makes me think you're thinking of this as a business.)

Only have a screenshot to show at the moment, but I'm working on an accessible color palette creator tool for web/UI design:

https://x.com/seanw_org/status/1815442179361317022

There's lots of tools in this space, but the key features of this is it lets you easily check the contrast of any color pair (not just against white, so you can check e.g. your text colors will contrast on off-white shades), it's for creating a full palette of colors vs a handful of brand colors (you always end up needing lighter/darker variants for things like borders and backgrounds), and you can alter how the hue/saturation/lightness varies across a whole swatch of colors with a few clicks (being able to visualise these curves also makes picking new colors really easy).

Feel free to reach out if you think this might be useful to you!

sunnybeetroot2• 2 years ago

This is great! One feature that I use ChatGPT for is “give me the closest foreground color to X that meets AAA accessibility on Y background color”. ChatGPT that calculates it with a python script. Has been super useful. Maybe it could work on your site?

seanwilson2• 2 years ago

Yeah, that's the kind of use case I want to make easy!

One of the tricky parts when working with ~100 colors is how you can easily tell the tool which pairs should always contrast so it can check them automatically, instead of you having to keep selecting pairs to check.

It's simple right now though to make all colors of the same grade have the same lightness so you get easy to remember contrast guarantees e.g. green-700 will have WCAG AA contrast on grey-100, and the same for any 700 (or above) vs 100 (or below) pairing.

I am currently working on developing a procedural, interpreted language that is amenable to genetic (evolutionary) programming.

I have decided to shelve my work on architectures that are biologically inspired for now. I was getting reasonable results with spiking neural networks and evolutionary training, but there are so many hyper parameters to think about and how they behave over time is really hard to predict. I was also struggling deeply with how to manage topological concerns like network growth over time.

With interpreted evolutionary programs, the memory access patterns are so much more ideal with the program counter stepping through (mostly) contiguous bytes vs totally insane recurrent spiking neural access patterns. You get so many more generations & candidates evaluated per unit time that it can make previously apparent "dead ends" viable, simply because you don't need to have extreme patience to find out anymore. I am discovering that iteration speed is the most important thing in this arena. The faster you find out how bad a certain parameter adjustment is, the sooner you can get to the good ones.

I am also working on an unrelated contract to integrate some back office banking systems. Not much worth discussing there.

chaosharmonic• 2 years ago

I've been building local tracking for job search listings[1] in my spare time, along with crawlers[2] as data sources. Mostly in bursts though, bc I've been juggling fleshing out the project with actually using the data. (On a related note, the current working state of the backend hasn't been pushed in a while, and still reconsidering the name.) It's mostly been an API up to this point, and most recently I've been chipping away at a frontend to accompany that, which is beginning to be useful on a personal level. In particular, I just got file upload working. But long-term, I see it as a hybrid between Tinder and a CRM (and I already have "swipe" animations working if not the actual touch handling), where you can bring your own data on jobs and companies -- however you get that, because I'm sure you can find better scraping processes -- and have a way of organizing them.

It's a lot of experiments. On the frontend, I'm dispensing with any design systems or styling libraries, and have opted for vanilla CSS and hand-rolled animations. I'm using React for now, just to get it scaffolded faster with tools I know already, but I've been eyeing a few others, for reasons that range from a standing curiosity about Web Components to new ones about signals. The backend stack is all Deno-based: it includes Astral for any scraping needs you might have, uses Oak for routing, and leverages kvdex for storage. (I also contributed `model.getOne` and `model.updateOne` to the latter as part of initially getting duplicate detection working.) My goal is to keep the whole thing light on external dependencies, outside of a few pragmatic options, and generally work more directly with platform or runtime (or in Deno's case stdlib) functionality where feasible.

I otherwise rebuilt my website over the last few months, using Lume for static site generation with similar aims about shipping something generally lighter (the content there is all Markdown, and so far, everything but the syntax highlighting and the ToC generation are built by hand). Additionally, I've been using it as a home for writing[3][4][5] and not just code, so that I have some other things I can show off. (The last one made the front page a couple weeks ago!)

Professionally, I recently founded a startup focusing on education in dentistry. I've developed a platform to discuss and interact with cases online which I use for my own teaching, and thought other might also be interested. I've made some of the custom components (image editor, 3D viewer) freely available: https://kigun.org/

Personally, I'm building a website which lets you quickly setup personal online dashboards, because I wanted to have an overview of all the sites I refresh often on one page: https://frankendash.com/

I'm making a cyberpunk-like ttrpg system, that should be roughly backwards compatible with the old gear catalogs. But it adds better progressions, some fairly innovative (I think) die rolling systems that make better use of party skills, and a number of ways that roleplay changes the rules, and visa versa.

kdickey• 2 years ago

I just (like today) started working on an open-source, self-hosted, e2e encrypted, and free password manager.

I’m writing the backend in Go, with a standard API layer to allow custom frontends. I will also be building “official” frontends for mobile apps, desktop apps, and browser extensions.

The main reason I’m doing this is because I don’t like the UI of other self-hosted password managers, and I hate relying on the security of cloud options.

Seeing as I just started work on it today, I don’t have much (not even a real name). If you want to follow along, heres the Github, https://github.com/dickeyy/passwords

My goal for this project is to provide teams and individuals with the ability to secure their passwords while also providing a clean and elegant experience.

LMK what you think!

denysvitali2• 2 years ago

Honest question, what's wrong with Vaultwarden?

zhoujianfu• 2 years ago

I had an idea for this you might want to consider adding: store the passwords/keys in the client, no server… but then shamir’s secret sharing to shard them along your contacts.

So when you open the app it asks you to choose five (?) friends you trust (who don’t know each other) from your contacts and it’ll ask them to install the app to help you store your secrets.

Then if you ever lose your phone or whatever when you reinstall the app you just have to remember at least three (?) of the five people you trusted and then will be able to restore your keys!

It would also ping the other contacts when open to make sure they still have your shards and redistribute them as you add/change/delete them.

I’m building an integration platform, think Zapier or Workato.

We’ve been hand coding full-service integration workflows for 2+ years on a large B2B agency model, and in parallel have been building a platform using what we’ve learned to build better abstractions.

We’re at an interesting point where almost all new workflows are being built on the platform, and we’re serving over 100 clients.

We’re prepping for public release in the next few months.

I have this creative writing website where writing friends can write branching fiction novels together. Sorta like choose-your-own-adventure, but more literary - third person past tense, actual characters and narrative arcs. Configurable number of choices at the bottom of every chapter, and as you're reading, if the choice label doesn't link to a chapter yet, you can write it. It's been floating around since 1996 or so, so my big project lately has been upgrading it. v1 was perl and gdmb files. v2 was php and codeigniter, and it's been limping along there for several years. When ChatGPT came out, I rewrote the whole thing for scala/play and that was super fun. Moved from ubuntu14 to ubuntu20, mysql5.5 to 8.0, etc. I'm done with the rewrite now but am still messing around with launching it, upgrading to ubuntu22 (done today), figuring out if I want to update jvm/scala/play before launching, etc. All this for only a group of six writers (so far)! But collectively we've written more than 425 chapters across a handful of stories, 450,000 words, and had a lot of laughs. I even wrote a snazzy graph visualization thing that animates the structure of the story maps. After I finish launching the thing on hardware/software that actually isn't EOL, I might open up membership to others.

Funny story, I had it released in the mid-90s. There are versions of it still on the wayback machine. You younger folks might not realize this but there was a time where there were a lot of fun internet happenings, and there was no spam. People hadn't figured out how to spam yet. There were also no T&C's or laws governing membership accounts. The first version of my site had no membership accounts. People would just create a chapter and assign a password for that chapter so no one else could edit it. And it was on GDBM, which could only handle one simultaneous connection.

Eventually, two things happened: the site got busy enough that people started experiencing errors when trying to submit/edit to the same story at the same time, and, spammers started realizing they could write chapters about certain erectile dysfunction medications. :) They also guessed some chapter passwords and overwrote them.

I didn't have a quick fix for this, plus I had ignored the site for a while, so by the time I realized, the site was overrun with spam and all my authors (who I had no way of contacting, remember: no user accounts) had disappeared.

So I took it offline for twenty years. I had copious backups, and over time I would reconstruct the story history. I had learned php by then from my career, and so I started rewriting the whole thing, which was honestly a huge project, especially because now every chapter has revision history. I had tried relaunching the site a couple of times without attracting any writers.

Then Covid happened and I was able to relaunch it and find writers. It's been fun since then. I have approximately zero commercial intent for this; I can't bear to turn on ads in the middle of an immersive reading/writing experience. Maybe someday paid accounts for extra features or a share of the copyright. My most fun idea for any sort of revenue is printed books for completed stories, or a mobile app "reader" with more features than ebook software. I think a wide release could be counterproductive since all the members currently kind of know each other, chat on Discord, and have writing nights. So it'll probably be a slow invite sort of thing.

I've been struggling to find a workflow that can easily extract knowledge and insights from audio content on the web and sync it with note-taking systems such as Notion, Readwise or Obsidian, so I decided to create a system that transcribes the audio, summarizes it and shares it with other applications.

Right now we are only targetting podcasts to Notion as the vertical slice for the MVP, but in the future we're looking to support "connectors" that can take in other forms of content such as audiobooks, videos, etc. and share it to other popular note-taking forms.

It's been an exciting journey so far and we're looking to launch soon!

I'm working on a little mobile game which surrounds locating and collecting VW beetles 'spots'.

I've been spending a lot of time in México over the last year and have been working on a photography project surrounding the VW Beetles (Vochos as they call them) you'll find all over the country. I'm inspired by the range of character of the Vochos and how they've become ingrained in the country's cultural landscape.

I realized I had a sort of hyper-niche problem where I was locating Vochos I'd like to shoot when I wasn't carrying my camera. I was getting annoyed with using Google Maps to list locations I'd like to return and shoot so I spent a weekend putting the app together and turning it into a game.

After using the app for a few weeks I've realized the spotting or hunting of the cars is the part I enjoy the most about my project and when I have the time I'd like to publicize it so others who find themselves in Vocho dense area can check it out if they'd like!

So back in 2021 I built a loyalty platform for a chain of gas stations in the Caribbean. Thought it would be a quick deliverable, then hands off.

It's turning into a full time side gig that's paid off in handful of batches (~$25K and running)

I'm trying to become a loyalty vendor API.

Would really like to work on my own interconnected systems of blogging tools and social media. Kinda a blend between having your own site and myspace? Not really targeting a market or anything like that, just think it would be cool to do for personal use and sharing with family and friends

wyclif3• 2 years ago

I'd really like to hear more about how this works and how you got it off the ground.

darrelld3• 2 years ago

Broad strokes:

I went to school with the son of the owner. For about 3 years off and on he'd been asking me about building apps, where he could find good devs, what price to pay.

I'd sent him some info, but never got too involved. Then the pandemic hit, and I found myself with a bit more time to kill, so I listened more to what they needed.

They basically wanted to get a loyalty program going at their gas stations and partner gas stations, but wanted custom rules which their current provider couldn't do with their off the shelf solution.

They also wanted to use one of those old school CC machines that were everywhere before the likes of square showed up. But getting your hands on those units is expensieve.

So I started planning it out. They needed to store customer data, and needed a point of sale device to swipe customer loyalty cards on, which needed to read in customer info, do a deduction, or a store credit top up and print a receipt.

I found a android terminal machine off alibaba, opened up android studio and started hacking away. I hadn't done more than a basic android hello world at this point.

For the backend I used django to get started quickly, and they were very happy to use the django built in admin panel to do stuff as needed, and view transactions.

After I got the devices talking to django, I had to integrate a loyalty vendor they already sourced, and just went along with it, but that was a mistake. The vendor points API doesn't really add much value on what django can already do for me, and my new goal is to become that vendor since I think I can do their product better.

But basically I iterated on it for about a year, launched a little over a year ago, still working out some edge cases and kinks, but they do roughly 25K transactions a month on devices spread out at over 20 stores.

They want to bring it to new islands, so I'm trying to remove some of my duct tape fixes with more stable fixes so that can be smooth sailing come next year.

EDIT: Might get back to writing and update with a much longer post. Draft:

I like leaderboards, and its a bit sad that Redis is the only optimal database for leaderboards. So, I'm attempting a drunken version of a statistic database that tracks stats and leaderboards in realtime. I guess the only major defining quality would be that in one step I can get both the sorted scores + entire row of linked user data.

For redis this is two steps: `ZRANGE leaderb 1 100` + `GET x1 x2 x3 x4 ... x100`.

It's mostly a refresher for deep C++ doodling, but maybe I'll use it in production for kicks.

treyd• 2 years ago

Have been working on a protocol library [1] meant to be a substitute for "JSON-RPC over HTTP/WebSocket". Part of the goal is to more natively support byte-oriented data structures and reduce overheads. It supports a bidirectional HTTP2-style "channel" concept, but without making any assumptions about how they're meant to be used. It also can be configured to require authentication of the client and/or server, but punts secrecy to a lower-level transport protocol. It uses Rust macros to generate traits and wrappers to make the ergonomics fairly easy.

Currently I've built a call/response RPC abstraction with it to use it for another project that I'm working on. Eventually I'd want to add a streaming message system beyond the basic call/response pattern. I also might like to ship some easy setup to bridge between these protocol abstractions and ZMQ, JSON-RPC, be able to behave like inetd, etc.

It's functional enough to use in non-production environments but not completely seriously yet. I'm working out the kinks and improving the DX by using it for that other project. There's still some easy improvements around the byte encoding that I still haven't gotten to yet.

My part has been to generate news headlines and weather maps using current news and weather information. The most interesting part for me has been deciphering the 1980's era graphics format, NAPLPS, which Prodigy uses and making a library to write files in the format. I treat the file format as a data transformation, taking the NAPLPS file generated so far and appending more commands to the end of it. The commands naturally pipe into each other in an idiomatic way in Elixir.

I’m working on Cyphernetes [1] which is a new query language for working with the Kubernetes API with a focus on highly connected operations. It’s inspired by Neo4j’s Cypher and views Kubernetes as a connected graph of resources.

It allows querying multiple resource kinds via their relationships (i.e. replicaset owns pod, service exposes deployment…) and easily crafting custom response payloads.

Lately I’ve introduced aggregation functions and the ability to visualize query results using ascii art.

This is a daily driver for me and I’m now mostly focused around features that will make it a complete kubectl alternative.

I found a way to add code to NFTs. The simplest way to understand it is that it is similar to Adobe flash.

I know that NFTs are down, but I have invented a way to add actual utility. I call them xNFTS - executable non fungible tokens. Imagine the famous Ape or Penguin NFTs - by adding my technology, the NFTs can change images, play music, or play games without installing anything.

I got a patent on the process and they work on any blockchain- or even off. the market is down, but I am very excited about tying web2 with web3.

It's meant to be a scripting language to be embedded in another program, generating HTML. Eventually I hope to make a CMS and this be my solution for easy templating.

Technical details: Written in C, the language has an x86_64 JIT compiler, but falls back to a bytecode VM so it should work on any architecture. The language itself is dynamically typed and garbage collected. Currently at 20K LOC (not counting blank lines or comments), with good test coverage and checking for memory leaks. It's been quite enjoyable!

I'm building an open source implementation of the Firebase RTDB server, that will be wire-compatible with Google's. This means that all the (already open sourced) SDKs will work pretty much as is, over REST or websockets. Security rules will also be fully supported. (The only meaningful caveat is that it's just the RTDB, so you need to deal with authentication yourself, and kinda shoehorn it into the existing APIs.)

Experiments with speech compression/processing. The modern approach to this (and pretty much everything else) is to transform the input data into a high-dimensional space, throw it into a neural net and cross your fingers. (the 'Whisper' STT runs in 512-dimensional space!). It works, but it's hardly elegant or compute-efficient. There's a certain art in doing things the 'old way', even if a million years of evolution decided neural-nets were the one true path.

I'm trying to bring the encryption benefits of MTLS, the security of X509 Name Constraints, and the improvements that have been made in the various clients libraries and operating systems to TLS behavior into a nice group, so that any small company, or even individual, can run their own CA infrastructure that puts the bug enterprises to shame (specifically, https://enroll.visaca.com/ already deserves a lot of shame).

I'm doing so by making it easier to mint certificates for your pods in k8s (https://gitlab.com/gauntletwizard_net/kubetls/-/tree/master), by writing documentation on how to create good root certs with cheap HSM backed keys, updating cfssl to work with name constraints (https://github.com/GauntletWizard/cfssl/tree/ted/constraints), and building tools to issue short-lived certificates to developers.

I'm putting the finishing touches on the major engine pieces for my NES game Tactus.

The one zone that's in the game is looking more polished than ever, but it's not going to be much of a game if there are only 4 levels. Next month is all about stage art, enemy design, and items to flesh out the new economy systems. Hopefully it all comes together, we'll see. It's a ton of pixel art, and I'm still learning my way around that craft.

I have some side projects that I work on alongside my regular job.

- TheFile.Ninja, which is a file manager with the Everything indexer built-in for extremely fast information retrieval. This allows you to quickly run file queries, and these queries can then be saved or even added as folders in the file system. When you open the folder, it automatically fills with the contents from the query. I have also created a service with LLM/AI that translates plain text into Everything's query language. This enables you to build very complex queries directly from plain text. For example, you can ask if any directories contain a certain file, and if this file is found and contains specific text, it will be displayed. You can learn more about the project at: https://thefile.ninja or watch https://youtu.be/JREufgkf5pk. This summer, I also built three smaller games (not fully finished but almost):

- ThrustMe!, a space/underwater cave exploration game (https://youtu.be/M0d7CSpEJ1E). It works on Android, Web, Windows, and possibly soon on iOS.

- MergeQuanta, a Tetris-like game where you merge matching blocks (color + shape) to make them disappear, taking surrounding blocks with the same shape along with them. There are also cement blocks and bombs. The game works well with touch and stylus but also on regular computers (https://youtu.be/VXvpzhi8ySE).

- Flip the Maze, a simple multi-dimensional maze game (https://www.youtube.com/watch?v=qOVRB0uAPIE).

What do you think about them?

rezolva2• 2 years ago

I am adding some more details about the projects.. The caves in the ThrustMe levels are fully procedural, every time you start the game you will get a new cave. I'll drop a link to a playable alpha-build (with bugs and it is untweaked so wait for the real release) on the web: https://thefile.ninja/thrust.htm

About QuantaMerge, this game is actually using a Physics engine for the falling blocks, it is not a regular Tetris clone..

meixger• 2 years ago

How does FileNinja compare to Total Commander?

rezolva2• 2 years ago

Total Commander was the original inspiration for thefile.ninja, but over time the context has moved more and more. The program should be easy to handle if you have used total commander., same keys, etc. However, the program has a much more modern interface and it is above all much faster in searches. It is so fast in searches that you can use searches as your own folders in the program.

I've been taking a (mental) break from programming and doing a lot more climbing, getting back into my body. After twenty years of boulder/sport/trad/big wall I've drifted into the dark art of rope solo. It's an wild way to climb that really appeals to my engineering brain - lots of deep knowledge about gear and the mountain intertwined with various logistical puzzles. Very rewarding when it works. The latest mission has been optimising my system a lot to start tackling bigger stuff.

pajeets3• 2 years ago

This was refreshing to read. Its great to see many people build themselves up on a site fixated on building for others...

jq-r• 2 years ago

Thats great to hear. I'm also working on my body after 2 spinal surgeries. Doing pilates each day, and additionally weight training and cycling on each alternating day.

For a skinny guy who never did any resistance training, this transformed my body to a lean, muscular type in what it seems to me like overnight. I cannot emphasize enough how good that was (and is) for the body. The body at first doesn't like it, but giving it a bit of consistency it learns and yearns for it.

The back pains I had are gone and even if they come back here and there they are much less intense and more manageable. Doing some impromptu exercises for couple of minutes fixes that too.

One of the biggest wtfs I had was when I decided to drill some holes in the wall because I was unable to for months after last surgery. I've grabbed my battery powered drill from the shed and was open mouthed how suddenly light that tool was. I literally checked if I've put the battery on. You don't notice the strength gain that much during normal work in the house, but do something which you know was heavy before and be amazed.

I definitely credit good people on this site for sharing their experiences. At first I thought that only weirdos and meatheads do resistance training and always had a mental image of steroid laden walking muscles. Then I've read that article where was the graph of expected life expectancy for a person taking on training in their forties vs not training and it really did concern me. As a guy in early forties I didn't want to spend the rest of my life with very poor quality of life/mobility. I didn't want to be glued to my computer all day long as it would virtually be the death of me.

I wanted to write a blog post about this journey (which is still short, but memory is fresh;) maybe to help geeks like us to see that being in front of the computer all day long is terrible. It works when you're young, but it absolutely doesn't as you get older. And everyone will get older whatever the younger people think. If I knew stuff I know now about fitness 20 years ago, I'm sure I would be 5 times more healthier, and I wouldn't need any spinal surgeries. But nobody told me anything and I thought "doing stuff" on the computer all day long is fine. "I'll be mobile and skinny even when much older, what else would I need?". Oh boy how wrong was I.

Awesome, I completely agree - having mobility and use of your body is such a blessing. All the best with your recovery =)

I am trying rebuild my virtual assistance business. For the longest time I have worked with realtors but the market has gone down and finding new contracts are hard.

Trying to move into doing virtual assistance for micropreneurs and sideprojects from now on exclusively. Task by task basis or regular contracts. Essentially the pitch is assign everything that is not sales and product. I think it is a good pitch targetted to folks who enjoy building stuff and considers making money out of it as a bonus. The moment they start answering support emails, and posting product updates they start to get burnt out. Trying to specialize in "burn out prevention" tasks mainly.

I am trying to figure out a way to get clients. Virtual Assistance is cheap and the competition is huge. The services are identical which essentially says, I will do what you will need me to do.

I'm working on a server driven UI framework for mobile apps.

Designers can push changes in Figma similar to a merge request, which can then be approved by product managers / developers and the apps UI updates on every device.

Devs don't have to touch UI anymore but can focus on pure logic.

Any app developed with this doesn't have to go through the usual release cycle for UI changes anymore.

This will decrease the time lag of mobile to web and makes it easier for us to implement and distribute campaigns.

We're in Alpha and two mobile apps with our technology are going to go live next months. A credit card app and a competitive player versus player mental arithmetic game.

I am building an Excel extension that lets me use LLMs in formulas. For example, I can write =PROMPT(A1:E1, "Extract keywords") in a cell to extract keywords from a row and drag the cell to apply the prompt to many other rows. I find this useful when I want to use AI for repetitive tasks that would normally require copy-pasting data in and out of a chat window many times.

I actually built it for my girlfriend who was writing a systematic review paper. She had to compare 7.500 papers against inclusion and exclusion criterias. She obviously did this manually because she cares about scientific integrity, but it sparked the idea to make an AI tool to automate repetitive tasks for people like her who would rather avoid programming. Now I just find it useful myself for a lot of ad-hoc analysis tasks like prompt engineering, rag tuning, and comparing model outputs from anthropic, openai, and google.

oulipo12• 2 years ago

Hey guys! We're engineers/designers from France, and we've built the Ultimate DIY Battery that you can repair and refill!

It works with 90% of the bikes/motor brands on the market, so I assumed that some people here might be interested, if they got a non-functional batteries but they still want to use their e-bike?

We believe that everybody should have control about stuff they own, and we should fight against planned obsolescence!

Here are a few videos about our founder on the battery itself, why we built it, and how to assemble it:

- What is the Gouach Battery: https://www.youtube.com/watch?v=NsuW1NPkvNk

- Presentation of the pack: https://www.youtube.com/watch?v=mLoCihE0eIA

- Presentation of the fireproof and waterproof casing: https://www.youtube.com/watch?v=EDJpt7RDbRM

Here are the juicy bits: https://docs.gouach.com

We'd love some feedback from the e-bike DIY builder community

Oh, and it's launching as a Kickstarter in September and there is an offer for early-backers here https://get.gouach.com/1 for a 25% discount on the battery!

You can follow us on Instagram https://www.instagram.com/gouach.batteries to get the latest news!

k4rli• 2 years ago

Would order instantly. I have a bunch of e-scooter 18650 battery packs that would be nice to convert to an e-bike one.

If Kickstarter is starting in Sept, then I guess it will be another 1-2 years.

samstave8• 2 years ago

>have a bunch of e-scooter 18650 battery packs

Where get?

There is a guy that rides the trail near me thats riding an ebike with a triangular battery pack that looks identical to one some HNer built here - He's too fast and I havent been able to stop him.

Another question for the DIY e-bik crowd, is what kind of OTS motor could one harvest, like a motor from an electric lawm mower, or edger, weed-wacker? Are there power tools where the electric motor is useable? (like how people originally used mower engines in goKarts and such?

Also, for fireproofing - mix Powdered Aerogel into a Silicon Slurry and dip the battery in that - the silicon and aerogel will make a heat sleeve thats quite fire resistant.

oulipo12• 2 years ago

Thanks for your message! The battery is already designed and in production, it's running on 1500 free-floating e-bikes in France without issues since around 2 years

We're doing a Kickstarter because we're a startup so we need the upfront money to buy the parts and build the battery! We expect to ship to Kickstarter customers in November 2024!

briansm5• 2 years ago

I thought the reason the packs are sealed is to stop amateurs from swapping in cells of differing voltages, which short each other out and cause sparking/fire hazards. There's a reason li-ion battery charging is current-limited, they have no internal resistance.

slim3• 2 years ago

from their homepage :

A Fireproof Casing which REALLY Works!

Scared of battery fires? I know that we are!

This is why our Infinite Battery comes with a casing that we designed to resist the heat of a fire, thanks to it's thick aluminum casing, and a design which dissipates heat quickly.

And YES THIS WORKS! We have put a massive effort in making our casing sustain the battery fire, and extensively tested it (videos coming soon), so you can sleep safely (and us too!!). See our complete fireproof testing on our documentation/FAQ

bittumenEntity• 2 years ago

As I understand it, it's somewhat the opposite for internal resistance. You need to have current limiting in place because the internal resistance of the cell is turning that current into heat, and heat is the enemy of batteries.

(Probably there's also a complicated chemical reason for current limiting that I don't fully grasp)

s0rce2• 2 years ago

Also spot welded connections work well, transfer reasonable amounts of current and don't tend to vibrate off during use. We tear down packs at my job and there are warnings inside some not to re-use cells for vapes, they really don't want you taking these apart. Larger packs like EVs and E-bikes are probably worth refurbishing and repairing.

oulipo12• 2 years ago

Indeed, we recommend swapping all the cells at once! But using our battery it means that you recover cells in perfect conditions that you can use in second life applications!

agumonkey• 2 years ago

oulipo, gouache.. these are names i haven't heard in a long time

jokes aside, i was curious if weld-less 18650 packs would be possible... seems like you guys answered that 10 years long question :)

kudos

oulipo12• 2 years ago

Haha! I'm a fan of OuLiPo :)

Yes! the pack is using 18650 cells, and a 21700 version is coming early next year!

ulnarkressty• 2 years ago

It's a very nice concept and I think it's much better than the held-together-with-duct-tape concepts usually seen in diy bike conversions.

That being said, I am a bit skeptical about your claims to be fireproof. Did you try to start a battery fire inside your enclosure? Aluminum melts at about 600C, while lithium burns much hotter than that.

oulipo12• 2 years ago

Thanks so much!!

Yes, it works because we're using a thick aluminum casing and a specific design to evacuate heat fast

Videos coming soon!

ttoinou• 2 years ago

Could this also be used to create external power stations with 230V plugs ? For example to take in a car / van, and recharge with solar panels

gridspy• 2 years ago

To do this with any DC battery you add a solar battery charger to accept the panels and an inverter to turn the DC into mains 230V you can use.

sgu999• 2 years ago

Super cool! Any plan on making different form factors? For electrified cargo bikes, the battery is better placed bellow the cargo [0] so a squarish and flatter pack would be nicer.

Since you have the ESP32 - can you emulate the Apple Airtag on it please.

I have a $7,000 Orbea E-bike and I have an Airtag hidden in it. Its a great feature.

Not sure if I could redo the Orbead Battery this way because its internal to the frame - but it does have an extended battery pack option - perhaps this could be wired to use that connector as your interface allows for any ebike it seems?

The post recently on HN about the flipper zero being able to emulate the airtag is pretty nifty, and you could use these guys effort:

https://news.ycombinator.com/item?id=41287031

I LOVE this project.

I want.

Actually, Can I ask that you add a LORA transceiver network in the build since you have the ESP32 (maybe update it to the ESP3250?) :-)

I'm the CEO of Tile and we are working on a line of products for theft.

As a genuine question, I'm very surprised that many people don't seem concerned that AirTags alert thieves to their presence. If your bike is stolen the thief will get the notification, even if they are on Android (with the new shared platform rogue tag detection).

I'm trying to understand the user psychology here - not pitch our own products.

Do you have any specific features you would like to prevent theft?

SeanAnderson• 2 years ago

I've mentioned my project a few times around HN, but might as well reiterate :)

I took some time off from work to teach myself Rust and to build a WASM colony simulation game. You've got a colony of ants, they're in a cold, foggy crater, and you help them grow and survive. The simulation runs 24/7, like a Tamagotchi, but a bit more complex, like a simplified RimWorld or Dwarf Fortress. I am hoping to design game play systems which focus on mental health, self-care, addiction, motivation, and personal growth and to use the gameplay as a means of encouraging awareness in the player.

https://github.com/MeoMix/symbiants

I haven't added any features in a while, unfortunately, but it's on my mind. For a while I was just adding whatever popped into my head, as a means of learning Rust, and I naively thought the full idea would crystallize with time, but it hasn't. So, I'm trying to take a step back and figure out how to actually make a coherent game that does justice to the mechanics I want to see in my simulation. I've spent a lot of time thinking rather than coding, but I'm optimistic that I'll get through this phase sooner or later. I will admit, though, that trying to take a novel approach with game design is overwhelming at times. That's okay, though! I'm enjoying the process of tinkering with the project and will likely continue tinkering on it for many years to come as a creative outlet for self-actualization.

taulien2• 2 years ago

I love ant games and I love Rim World! I think its a great idea to combine those into a 24/7 game!

I’ve been thinking/slowly building a service that hosts Kubernetes control planes. Bring your own worker nodes. Users can get a fully managed control plane (upgrades, HA, etc.) in their region of choice and can use whatever workers they want—be it cloud VMs, bare metal or your laptop too.

I’ll eventually open source the single binary agent that’ll bootstrap a host into a K8s node. Just run it rootless with a join URL and voilà!

Also in the pipeline is a global load balancer service (for your clusters).

What do y’all reckon? Interesting? Yay/nay?

solatic• 2 years ago

Kubernetes is really built on the assumption that workers are in the same LAN as the control plane. Long latency between the control plane and workers affects workload reliability; heartbeats need to be configured with longer timeouts, for example. Pod-to-pod communication, where pods run in regions on opposite sides of the globe, supposedly on the same pod network CIDR, is also going to be flaky. There's a long history of projects attempting to take LAN-local designs and make them resistant to regional failure by superimposing a LAN on top of a WAN and it never works as intended. Furthermore, various service meshes already present ways of helping to direct/shape traffic between clusters (i.e. between regions), when service architecture evolves to truly support multiple regions.

You run a risk of building something that seems to "work" and falls apart for non-obvious, head-scratching reasons for many or most users.

icy2• 2 years ago

Kubernetes is really built on the assumption that workers are in the same LAN as the control plane. Long latency between the control plane and workers affects workload reliability; heartbeats need to be configured with longer timeouts, for example.

Yep, and that's why I'm designing this to provision control planes as close to the user's workloads as possible (sub ~100ms latency, which is plenty acceptable for reliability; the likes of Scaleway do similar).

Pod-to-pod communication, where pods run in regions on opposite sides of the globe, supposedly on the same pod network CIDR, is also going to be flaky

Certainly, but this is not something that I as control plane provider care about -- it's a design decision the user has to account for, and I consider this freedom of choice a nice one to have.

I suppose the main sell here (and the few folks I've spoken to seem to agree) is the flexibility a decoupled control plane offers. Being able to migrate your bare metal setup to "managed" K8s; running a homelab cluster without dealing with the ops (upgrades, cert rotations, etc.); or simply being able to use VMs from cheaper cloud providers.

But yeah, it's definitely a hard problem but solvable within the right constraints.

I have started working on some open source actuarial tooling. Mostly relevant for non-life pricing.

The open tooling is quite lacking in the sense that one has to create a lot of stuff manually. Especially for the evaluations, even though most of them are quite common in the actuarial realm.

Also I wanted to tinker with Jax. So I am basing all on Jax, polars, seaborn/matplotlib and scipy.

I already have lift plots and Poisson regression in Jax. I’ll keep adding to it over the next months as time allows.

I had a 6 month break but beside that it was daily grind from morning to evening. I'll be going online later this year.

Most funny thing is that the toughest part related to the project had nothing to do with coding or tech. But finding a free domain. I had no idea 99% of the .com domains are just squatters.

I'm working on a podcast and audio media monitoring and research platform. Easily the most complex thing I've built. But still so much more to do to make it truly useful. Testing PR and public affairs use cases at the moment.

https://listenalert.com

I used to work for a media monitoring company but was instantly struck by how old fashion everything was. And the total reliance on boolean searches meant only experts could find relevant information. This still appears to be the case for most players in the industry.

So I'm building a platform that finds what is important before you look for it. Novel entity linking, and sentiment analysis plus speaker tracking. It has come a long way from the proof of concept. Focused on audio media at the moment as it is the hardest to index compared to news articles in my opinion. And the hypothesis is audio media such as podcasts can contain so many juicy insights.

Next steps are converting pilot customers to paying customers, testing more markets (based in a tiny market now), raise a small pre-seed (bootstrapped at the moment), and quickly evolve the product based on feedback.

yes, definitely some skin deep similarities! We both transcribe podcasts, but what we do after that is very different ;-) (also, i'm a fan of his podcast).

There is also more generally Mention, Brand24, Meltwater, etc, in the media monitoring space. But all are generally weak in the audio media space.

When we stop looking at audio media like a newspaper article, things get more interesting.

I wanted to record more of my life, but I found that the act of noting it down was too cumbersome. Looking to minimize friction, I created a Telegram bot that saves all messages you send it into a Google Spreadsheet.

Hashtags can be used to split the text into sheets and columns, if so desired. Besides jotting down quick thoughts, this is very handy for short-form journaling such as tracking expenses, workouts, mood, period, weight, diet, etc., with the added bonus of easy charting and summarization from within the spreadsheet. It also supports pictures and other attachments that are uploaded automatically to Google Drive and linked into the spreadsheet.

I’ve been working on a project to make SaaS (and really any software) pricing and packaging easier. Think things like plans, entitlements, dimensions, metering, subscription migrations, onboarding, and experimentation, all completely independent from billing and payment processing solutions. We can integrate with things like Stripe where we’ll mirror products, customers, and subscriptions, but it’s totally optional.

We’re 100% bootstrapped by way of a previous acquisition and just very-soft launched after talking to a lot of folks at companies of all sizes. Seems like most people end up cobbling this stuff together with various levels of sophistication, which is basically what we did a few times over at previous companies with varying levels of success.

I'm scratching an itch. I'm a huge fan of system monitoring and alerting when they go down. It allows the engineers in charge of the production systems to sleep well knowing that things are working.

There's a gap for email monitoring. How many times did you have to awkwardly explain why the notification emails in your app stopped sending a month ago? Or that time when the weekly summary report did no go out on Friday, and on Monday you were chewed out by the boss? Or when Jerry went on vacation and neglected to send the weekly marketing campaign email.With

[I'm building https://wasitsent.com - you get an alert when your emails *stop* sending. It's like an uptime monitor for email sending. If something breaks your email sending process, we'll let you know.

If you would like to see such a service, or have feedback (positive AND negative) about it, please let me know. If you heard of other companies offering something like this, I'd love to know as well.

simonjgreen• 2 years ago

A long time ago I built a Nagios script for verifying email end to end. It would trigger a test email to be sent from the app to a known mailbox and measure the time to receipt in that mailbox. Simple but extremely effective, and several times it caught a failing in the mail stack somewhere.

It also got used to validate enquires@/hello@/contact forms were delivering, especially to set small business owners minds at rest.

gnopgnip2• 2 years ago

We use a similar email monitoring tool from https://ert.digitconsulting.net/ It integrates with our RMM. So there is definitely a demand for a service like this. But I would expect that paying customers will want it to integrate with a monitoring platform, more than just a message on slack/teams

I think you need to work on the pitch a bit and probably tone it down. Multiplying the promises under "Skills and Insights You'll Acquire" with "Who This Book Is For" just seem wildly unrealistic for one book and an oversell.

I get the vibe of a "become a 10x developer from scratch and land a rock star job in a month" bootcamp. 2/3 of your audience are likely to have seen enough of this already to be turned off. Meanwhile, perhaps some more junior will be intimidated and say "not yet" by the supposed advanced level (the material is also targeting people 10-20 years ahead in their careers after all...)

If you write another book in the future, I'd suggest splitting it into a couple more focused ones, rather than trying to cover all these dimensions for all seniority levels at the same time.

Right now I'm working on withdrawing money from cs.money and Steam balance.

It's been sitting there for years, and I finally found health, time, and dedication to withdraw it.

On cs.money I had $35k and on Steam balance I had $12k.

The only way to get money from cs.money trade mode is to buy skins and sell them somewhere else.

On Steam, on the other hand, I buy Steam Decks via Steam balance and sell them locally.

I have sold 3 in the last 2 days.

Last 2 days I've been taking a short break from coding a bot for cs.money to recover some health back (I have RSI).

damn. That is a lot of skins. Yea, make sense to try to automate that. Approx how much time does it take to turn it into money?

It's fast and easy if you are willing to accept big losses, but slow and hard if you want to save thousands of dollars.

However, it's important not to be too cheap - a friend of mine was stuck with a $150,000 balance on CS.Money because he only wanted to withdraw money in the most optimal way.

Been working on a small temperature and humidity sensor using cheap components and a Raspberry Pi Zero 2 W. Using https://gokrazy.org/ to turn it in to a little appliance.

I've gotten quite carried away with a web interface and custom on-disk (on-sd card?) storage format based on Facebook's Gorilla paper.

I've realised that where it'll be deployed it will only have access to a public guest WiFi, so a remote server hosting the dashboard makes sense. So now it sends the compressed time-series over a TCP connection to a server component, hoping to bypass WiFi captive portals. Might need to use UDP to make it look like DNS or perhaps NTP. I haven't tested it on-site yet.

It has been a very fun and rewarding project so far. Looking forward to deploying it and getting remote updates working if I can get it to work with Tailscale on the guest WiFi. If anyone has any tips on circumventing captive portals and sending really small amounts of data through, I'd love to hear it!

Hey. I’m building https://www.unwrangle.com to make it easier to scrape data from ecommerce and other sites that are hard to scrape.

It’s like Apify but my goal is to make it easier to use

Currently, I have APIs and scrapers that work with platforms like Google Maps, Yelp and Amazon. The APIs are useful to get data immediately and scrapers to extract information from many URLs.

The plan is to add more general purpose APIs like an HTML API, Markdown API and eventually features to build your own api and scrapers with AI.

There’s a lot of tools in the space nowadays but imo they are all flaky. My intention with unwrangle is to offer a way to scrape any site that just works without the need for any config or complicated pricing. The project is at a little over $1000 MRR. Marketing it has been and continues to be a big challenge. I’m bootstrapping solo and hoping to reach 5-10k MRR in the following months. Plan for that is to consistently improve offering and conduct marketing experiments.

What I find interesting about it: I’m offering easy ways to scrape sites on which antibot is really hard to bypass like Twitter, paywalled sites, LinkedIn, etc. The ability to build crawlers without writing any code is kinda cool. User who would normally not have used web data are scheduling scraping jobs and using the data for analysis. For the HTML API I’m thinking of doing an interesting spin on what others like ScrapingBee are doing and abstracting the needless config like premium proxy etc. and just effectively offering a higher # of requests. Also for the build your own scraper, offering users a way to create a parser with a prompt and use it in a single browser session to collect data from many pages saves hassle compared to a synchronous API approach

My wife and I are building Spruce, a Slack app that autocorrects typos in your messages: https://spruce.so/

The motivation behind this was twofold. Firstly, we're both the type of people who often edit our Slack messages (or any other messages like WhatsApp) to correct mistakes. Secondly, my wife is a PMM at a tech company, but she can't code. I've been telling her that anyone can create a decent product with the help of LLMs and tools like Replit, but she usually just rolls her eyes. So, on a flight from London to SF, I suggested we build Spruce. The idea was that she would take the lead and rely on LLMs (ChatGPT + Ollama for when the wonderful Delta internet wasn't working), and she could also treat me as a [more intelligent] LLM. After ~12 hours and a few small arguments, Spruce was born. :)

Some random learnings, top of mind:

1. A non-technical person, even with current LLMs (GPT 4.5), can't go from idea to shipped product without at least some help from a technical person.

2. I now make even more typos because my habit is to type as fast as possible, often without even pressing the space bar. Spruce autocorrects everything in Slack, but when I'm using other products, I feel incomplete.

3. Although I'm practically a native English speaker, it's still my second language. I've added a feature to Spruce, just for myself for now, that DMs me if I make really obvious grammar/English mistakes in my messages. I decided to do this after one of my colleagues, who is very English, said "for prosperity" instead of "for posterity" in several messages, and another said "for all intensive purposes" instead of "for all intents and purposes." It's been a very cool development, at least for me! It's fun because a) it has a nice tone, and b) it's not verbose and only nudges you on major mistakes, and only up to twice a day. Anyway, feel free to give it a try: https://spruce.so/

P.S. This Slack app necessarily needs the permissions it has because it needs to be able to read and edit your messages everywhere (e.g., public channels, private channels, DMs, etc.). Don't install it if that freaks you out. However, it's easy to remove Slack apps, so there's no harm in giving it a try.

Self Host Blocks https://github.com/ibizaman/selfhostblocks is a modular server management based on NixOS modules and focused on best practices. The manual can be found here https://shb.skarabox.com/

Compared to others, its goal is to make best practices easy, be declarative, robust and fully featured.

I’m a self hosting and data sovereignty advocate and this project is my contribution to this space.

Best practices easy is made by adding a layer on top of the stock nixpkgs modules that make for example Vaultwarden easy to secure (/admin behind SSO with Authelia) and easy to backup. One doesn’t need to understand how to setup Authelia nor what folders to backup. That is taken care for you. https://shb.skarabox.com/services-vaultwarden.html

Declarative is taken care by NixOS but it goes further than the stock nixpkgs modules. For example it installs the needed Nextcloud apps for LDAP and SSO fully unattended. https://shb.skarabox.com/services-nextcloud.html#services-ne...

Robust thanks NixOS being a declarative OS, for example by adding a grub menu for every new deployment, making rollbacks easy. But also thanks to extensive tests that for example validates that the SSO integrations do not break on upgrades.

Fully featured because for every service it provides, it makes setting up the reverse proxy, backup, LDAP, SSO, etc. easy and importantly in a standardized way thanks to contracts I’m adding https://shb.skarabox.com/contracts.html

All of this is not meant to stay in this project though. I’m slowly working towards upstreaming everything into nixpkgs. I’m starting with upstreaming a feature that allows out of band secrets to be interpolated into config files easily https://github.com/NixOS/nixpkgs/pull/328472 I make extensive use of this is Self Host Blocks already.

Finally, I’m using this project for my home server and one in my parent’s place. So I’m using it in “prod” already.

We’re building an off the shelf software and ECU that allows you to convert anything to EV (classics and low volume OEMs) with enough tweakable knobs to suit every application.

There are some players in this space already, but we have repurposed some OEM grade hardware that we usually reserve for the big players and so we can offer differentiating features such as DC fast charging, bidirectional/V2X, and things like this to the retrofit market.

B2B to start with.

I'm working on a paid Ruby gem for bespoke Stripe subscription integrations. It cuts down integration time from +6 months to less than a day, and handles many Stripe API pitfalls.

Stripe has a "developer friendly" and "easy to use" reputation. But, since 2019 the EU regulation has stepped in and made things more complex with 2nd factor authentication for payments (3DS/SCA). This made payment integrations way more complex. Integrating Stripe subscriptions now easily takes 6 man-months (I'm being very optimistic here).

Also, there are some basic scenarios that are hard to get right:

- Creating a paid subscription and ensure a customer always has a card on file (this one is almost impossible). - Upgrading a free ($0) plan to a paid one. - Upgrading paid plans, eg $10 to $100/month and ensuring immediate payment. - Guarantee customer Tax location, keep the flow simple.

I made a video analyzing Stripe integration of a successful SaaS company (+$100M valuation). I first paid $30, then upgraded to their highest $2000/month plan - for free!

https://www.youtube.com/watch?v=YuXp7V4nanU

The gem I'm working on is intended to be used with Ruby on Rails apps. It covers all the above mentioned hard cases, and irons out many more Stripe API kinks. And yes, it handles the basic-but-impossible "ensure customer always has card on file if they start paid subscription".

After buying the gem you can hand-off the task to the junior developer (it's that simple). They follow the integration tutorial: follow the steps for Stripe dashboard config, do the local env config, done.

The product (Ruby gem itself) is ready. I'm now working on the web app, tutorials etc. If anyone wants an early, guided access, please email me - contact is in the profile.

vinc3• 2 years ago

Interesting idea, getting Stripe to work perfectly in production for a global product is not as easy as it was, it really takes a while to fix all edge cases.

brunosutic2• 2 years ago

Sometimes it's not about the "edge cases" and handling Stripe quirks. The main design consideration for global Stripe integrations is SCA/3DS or "payment confirmations".

If you implement something, then add SCA/3DS "payment confirmations" later on, I think it's impossible to fix that.

cmenge• 2 years ago

Interesting. I built a recurring billing startup and was always wondering how Stripe dealt with those edge cases...

As a note, I watched the video, the company name does become visible at least twice, once from 6:33 in the header pane and URL and also at the very beginning (Company Insights pane -> below "Powered by AI" the AI repeats the company name)

I have been working on a little price tracker for the Hetzner Dedicated Server auction (https://radar.iodev.org/). Using Sveltekit for the first time, and decided to go frontend only with duckdb-wasm.

I pull the data every hour with a GitHub action and redeploy the site nightly. The duckdb is regenerated every time and I can flexibly change its structure as required. So far I didn’t change much (eg. no normalization) since it’s not really needed. It also turns out to be surprisingly small, with compression a few megabytes. I haven’t written much SQL in some time and duckdb is very powerful.

Most of the texts are AI generated as I’m usually very bad coming up with this. I really gotta learn that one day. Webdesign is the other weakness, but with all these UI libraries these days it’s less of a problem.

I guess it’s pretty niche, but maybe interesting for some.

It’s a fun little project.

An app for sharing photos with a large group of people while still preserving the privacy of the people in the picture who don’t know each other.

Our kid’s nursery school posts a lot of photos to Facebook, and we’ve asked them not to post photos of him. They’re (mostly) respecting our wishes, but we still have a bit of FOMO over the pictures of kids having fun, and wish we could see pictures of our son having fun too.

The goal is that the nursery would be able to upload photos and parents can see only their own child’s face, other children are pixelated.

Still early stages but got a working prototype, and I’m enjoying the building process.

I'm working on a trip planner for vegans. This is designed to solve my particular problem as a full time (vegan) nomad who likes to stay in walkable cities.

I noticed that sometimes, I book accommodations in a new city without realizing I'm very far from the nearest vegan restaurant, having to walk for a really long time to get food, and sometimes getting there after the kitchen is already closed.

The planner helps me find hotels/airbnbs that are within 15 minute walk of at least 3 different vegan restaurants - makes my life so much easier!

One of my hobbies is trying to predict foreign exchange prices (usually EURUSD tbh, but others as well).

I enjoy finding out the actual best-case performance of various technical analysis indicators, and popular "systems", by optimising the indicator's parameters to find the best long term performance. I also design my own indicators and systems in the same way.

To this end I have a C++ ImGUI desktop app with charting capabilities, and optimisation using differential evolution. The app has its operation driven by a c++ class that controls all aspects of its running, by means of various callbacks.

This enables me to test lots of strategies quickly, exploring the parameter space with the optimisation functions.

I've considered open sourcing the app, though I'm not sure there would be any interest. The codebase would need cleaning up first anyway! :-)

It is all manageable via an API and provides a Kafka API for streaming data (RedPanda under the hood).

They're driven by what problems I see at work and while playing with other weekend projects so coverage may be asymmetric (some parts are well covered, others that should be are absent <<ie. documentation>>).

Thank you! This was initially a startup idea but it was very hard to sell a cyber security solution with a very bare bones product to companies large enough to have this problem. Because the required features of such large orgs are just too much for such an early stage team.

So I'm now doing it a bit as a side project but I hope to at some point also offer a paid version to fund development long term.

I'm loving this. This could be generalised to other manual actions as well, e.g. stuff like the K8S API.

Yes, I already thought about this. In theory all "production access", be it ssh, k8s commands, database access of any kind or even a ruby shell could go through such a a flow.

taulien2• 2 years ago

Hi!

In the best case, the developers of e-commerce website create unit-, integration-, and functional tests to make sure, they do not break existing functionality.

But a website is not only code. Its also data and configuration.

Since these types of configuration (e.g. prices, legal texts, bonusses) can change quite often and can get quite complex from the business perspective, it does not make sense to have developers create automatically executable tests to make sure, the website is configured as it should be.

And its often not the developers who change the configuration. Maybe its a product manager, a marketeer or the ceo.

These people often do not know if they configured something correctly. In additiom, they often don't get any notification, if an process, that is important for them, breaks due to a misconfiguration or some bug in the code (not every code base has a test coverage of 100%).

So, I am creating a No-Code Black Box E2E Monitoring Tool, that the process owners/configurators can use to regularly check, if everything is working fine.

Working on a web app to check various metrics on cloud servers (or virtual machines on-prem) and suggest optimizations to reduce cloud waste (and costs). I'm basically automating a good part of the infrastructure maintenance I was doing as a full-stack dev in my previous job.

There are already a lot of services to right-size servers, but I want to focus on small teams that might not have a full-time devops yet and lack the time to check every server manually.

The app will be simple with an educational part, it should be like having access to continuous audits on our infrastructure, just like the CI/CD tools we use on our codebase.

It already helped me at home to reduce the load on my oldest Raspberry Pi by shifting some services to a newer one that was mostly idle and right-sizing some VMs in the Proxmox cluster of the rack in my homelab. Having a green check next to each server name is a good motivation!

Another thing that is scratching my own itch is server discovery (especially in a multi-cloud environment) and integrations because it's just so easy to forget some servers in a cloud when you do a lot of experiments and keep paying for them for months.

The MVP is getting ready to launch, I'm making the landing page right now, and then I hope to find some early adopters to iterate on the app and make it useful to other devs. I'm also thinking about open-sourcing it.

I'm interested in having conversations to discover the pain points of other people in that space, so feel free to reach out to me!

Hi! I'm working on https://UpdateMaker.com. UpdateMaker is a super-simple widget for delivering in-app updates and notifications to users.

As a dev, I always want to tell users about our latest updates, but making front-end updates requires a whole production deploy, and a backend notification service is a lot to set up. UpdateMaker makes it easy to manage updates without an engineering cycle.

UpdateMaker lets you copy-paste our widget into your website, and then you can push update notifications to your users. You can customize the look and feel, schedule updates, track user engagement, and make it conditional on pages the user might visit. We manage all the cookie-handling so the user only sees updates they haven't seen before. It's been super useful for us!

From there, UpdateMaker also automatically exports all your updates as a changelog that you can publish for your users or SEO :)

Few recent side projects:

- a fact management tool based on a timeline. I have a complex legal situation, so I created a tool to store information about events. I can prioritize and tag the events, attach files to them, and have small workflow on them, and then filter the timeline based on the tags/priorities/workflow states. It is very helpful, because the amount of events and data was too much to handle mentally. I am using Django/HTMX/AlpineJS.

- a dance event calendar for dance events in Finland, where both artists and venues can add events. The data is stuctured, which allows me to make views for each performer, venue etc. Mostly Django, but some HTMX/AlpineJS as well for complex screens

- for the dance event calendar, I have created a support site that uses ChatGPT to handle two first steps for incoming support emails/questions. First it categorizes the question, and then tries to answer it based on FAQ. If it fails, it summarizes the issue (and possibly asks few basic questions related to it) and forwards it to me.

I'm working on https://runs-on.com, a self-hosted solution to get 10x cheaper GitHub Actions runners with support for Linux x64 and arm64. This month I've been refining Windows support and hopefully this gets fully shipped before Aug 31st!

waiwai933• 2 years ago

We're really looking forward to Windows support - I don't think any Actions runners vendors supports Windows at the moment and we were looking at building our own runners as a result, but if this launches soon, we'd be very keen to try it out!

I'm integrating daily steps walked into my workout/nutrition tracking app EverBeat for Android. I've noticed that this is an important metric for many people interested in losing some weight.

I estimate burned calories on the minute-to-minute level for all activities, which is a fun challenge.

For the steps to calories conversion, I require time and distance walked. Unfortunately it's surprisingly difficult to get some kind of distance information from Android. Google Fit API provides this data, but will be killed soon. The RecordingAPI will hopefully provide this in the future, but not yet...

I’m working on a few things:

- Micro SaaS https://yasl.at, link shortening with custom meta data for link previews on messengers/social media, see my blog post for more details: https://yasl.at/dKpNnZ

- A web game called Wizencraft (https://wizencraft.com) which is a logic puzzle to guess the right order of items as quickly as possible which lets you compete with other players, solve daily challenges in groups and let’s you grind thousands of items, it's a very early alpha and I'm building it in public very iteratively and not polished at first, see more details here: https://yasl.at/XnoDtY

- And last but not least I started to build a not yet published simple dashboard for analytics where I can plugin my self-hosted database very easily. You can just write SQL queries for MongoDB, Clickhouse, Postgresql in a single YAML which defines the query and how a chart looks like on the dashboard.

The idea came from the fact that using other dashboard/analytic tools always is a hassle, existing analytics dashboards I used for products are not easy to copy, replicate or adjust and it's mostly doable solely via clicking in a complex frontend instead of defining it simply via a configuration and the available offerings are charging large.

I'm planning to have the chart definition editable via web interface and is stored locally as files which can be versioned and managed by git and can connected to the web interface with a simple docker container (this brings the analytics dashboard to the product source code itself and can be easily copied/adjusted again for new products). Happy to share more and once the first version of the dashboard is ready to use (in the coming weeks...).

---

Would love your thoughts on all of this and especially the analytics dashboard. Did you you face similar issues/problems with existing solutions (or if i can stop and actually use an existing solution which does what I'd like to have).

I’m working on a test integration tool. You write your tests declaratively using YAML (ie. setup the environment, databases, etc., load fixtures, make api calls or db calls, and check assertions), so it’s completely language agnostic, which makes it perfect for grey-box/black-box testing. This way of testing also ensures you’re testing functional, business cases, and gives great stability on an exposed interface, because everything runs with real dbs, real queues and so on. From experience, this way of testing hits the perfect balance between reliability, usefulness, maintainability (when done right), and verbosity (at a previous company we replaced the tests on all of our layers with this kind of integration tests and it ended up being the most stable code base and test harness we ever worked on).

I’m currently polishing the logs and reports as much as possible, and then I’ll add support for more tools (Kafka, Rabbit, Nats, etc.). I have tons of features in mind to improve UX, speed, and bring more value to the tests.

Down the line, I want to find a business model for this tool and sell it, but I need to do a lot of thinking on this side since I’ve never done this before.

Yeah I didn’t came up with the idea first, at my work we used an in house solution[1] but it had lots of shortcomings (hard to read output, hard to debug tests, virtually no documentation, and the code was very hard to extend and fix). My plan is to fix all these issues and more :)

Hey HN! I'm still working on my Docker Swarm dashboard, Lunni: https://lunni.dev/

Lunni essentially takes docker-compose.yml and deploys it on a server. Currently we're using Portainer as the backend, which in turn just runs `docker stack deploy`. I'm reimplementing the stack deployment code from scratch which will allow us to support latest Compose spec and extend it as we need (and perhaps support orchestrators other than Swarm in the future).

https://snaptail.dev - during the past few days I was exploring concept of single source file applications where you can hide the build system.

It works great for fast prototyping or building an internal/local apps.

I'm currently working on a PDF search engine that will index and then search through several thousand pdfs. As a tabletop role-player and former researcher, I've always wanted a simple tool to do this, and I hope I won't be the only one to benefit from it. This is my first project of this scale and I hope to be able to show it here soon.

On the technical side, it's a desktop application coded entirely in java with a javaFX interface. No AI or online data uploads, just the Lucene search engine and PDFium for PDF rendering.

Here is a very short demo : https://youtu.be/CGo9JRUByGA

I’ve been realizing that while I’ve found an incredibly effective solution to a problem I keep having, it does not automatically lend itself to becoming a wildly thriving business. If the problem that is being solved is a somewhat infrequent one (once a year or less), and not applicable to a super-wide audience (think Facebook), then it simply won’t result in enough business to commit to fully.

I built a domain hunter (with availability checks) for .com domains based on idea prompts and while I see people purchase domains all the time through it, they won’t even shell out $3 to get any extras or a list of more than three domain ideas or so. Zero willingness to pay anything, but high success rates on search and result conversion.

they won’t even shell out $3 to get any extras or a list of more than three domain ideas or so.

A companion that you chat with to keep track of your health symptoms. I was inspired by seeing family members go to their doctors appointments and not knowing the important symptoms to report in their short appointments.

Right now, it's Ruth, a companion you can WhatsApp with. She will take your history and record your symptoms, then you can ask her to summarise it before your appointment.

Try out the prototype on WhatsApp: +1 (516) 734-6593

bsenftner• 2 years ago

I'm working in the final features for an office productivity suite with deep AI integration. I think the current slapping of a chat window on software is pretty tame, if not lame. So, in addition to that chat window that replies with conversational chat, I've got over a dozen integrated into software tools LLMs that when you ask them things, their output is programmatic and either modifies the data of what you're working on, or or performs some type of modification to the software tool in use. The tools include a complete word processor, where the AI knows the word processor's API and can directly manipulate the document in the word processor, likewise for a spreadsheet, and there is a "prompt engineer" interface where one can clone, modify, and create new LLM Agents that have deep access to the APIs of the tools, the data in the tools, and the wider application framework.

This has been in development for 3 years, and I've got an immigration law firm using it, with about 1/3rd of the LLM agents being immigration law specialist agents of some type.

I'm just wrapping up transforming the system from being immigration law specific to being generic, capable of operating in any industry. I previously made a "do it yourself: build your own home solar energy system" as a proof of concept that this framework could be modified in such a way, which I put online for a few months and then took down, having proved what I wanted.

I've got multiple creative writing 'bots: legal, technical documentation, creative writing, and code authoring. I've got multiple spreadsheet 'bots: create any standard spreadsheet form on demand, reverse engineer and explain complex spreadsheets, and co-author spreadsheets interactively with the human user, guiding them through the understanding of the spreadsheet being built. I've got foreign language translation agents that allow people without a common language to speak to one another through the voice transcription interfaces.

And the users are never copying and pasting LLM outputs from one place to another, that integration is built in to the business logic of the software: ask a chatbot to write a document, the output does directly to the word processor and the document is created, likewise for spreadsheets, likewise for talking to the "projectBot" and asking "what's the state of this project?" and a detailed report is generated.

I've also been making the app itself multi-lingual, and multi-skinned so it can be refaced for different cultures, demographics, and industries. I've been calling it "AI CMS" but that is meaningless to far too many. I'm considering calling it "Midom Office AI" because that sounds like "my dumb AI" and I'm generally sarcastic, considering an anti-gushing sarcastic marketing angle on the software. Rather than everyone's else's over praising, I'll have just some confident smuck referencing how he's got an entire team of AI experts helping him, enabling him to be calm and cool in the face of all the deadline pressures, he sips lemonade while his AI team works for him, and not him for it. We'll see what my "marketingBot" says...

Working on an NFL stats & visualisation project, the working title is American Football Insights. It's a hobby project, I'm not planning to charge for. I did a bit of work on this a few years ago, and I found that analysing the stats, you can gain insights, which you can't really from just watching the games. It was prompted by the upcoming NFL season.

Things I'm thinking about...I had an idea for a centralised local DB where I collected all kinds of stats on my life, all in one place. They're already being collected on various platforms, I thought 'why not make them my own, and maybe there's something to gain by pulling them together?'.

I'm building a developer tool for working with FHIR APIs called "Vanya Client".

- https://vanyalabs.com/

FHIR is a data standard for sharing healthcare data. It's in use all around the world by healthcare, health insurance and medtech companies as well as researchers working with healthcare data.

Vanya grew out of my own frustrations as a developer working with FHIR. I wanted an easier way to see the data behind the APIs. To say Postman is not ideal for working with this data is a major understatement.

We're a few months away from a commercial release, and have an MVP available for download right now. We're very much building in public and have a strong user base already all around the world.

Just finished a Sunday morning release of the latest version. Looking forward to the next 6 months!

I am working alone on https://tree-of-knowledge.org

This is a hierarchical representation of any given piece of knowledge.

It starts with a tree root node that you specify (let's say Kung fu), then it branches out into multiples subcategories (techniques, styles, philosophy, weaponry, ect...) and then you can click on these subcategories to branch out even more into the graphical tree.

This is all generated on-the-fly with Claude 3.5. There is no limit to what knowledge you might explore.

The killer feature is that it is totally free and does not require to login. Just click the link and have fun. I'll keep it free like that, as long as I can.

I hope you like it guys because it is the best project that I have up my sleeve.

Enjoy!,

john_minsk• 2 years ago

This is super cool!

As a marketing spin for this - consider packaging it into Nvidia NIM format and make it generate 3D graph as 3D OpenUSD scene. From where I'm standing this route has a lot of potential.

Also if you never looked into it there is a project called wikidata. There each object contains a unique ID and hierarchy, which helps build semantic web. Exploring their data using your interface might be effective. (please check similar projects though as an idea seems straightforward and someone might have already done that for them)

I like this project but I don't think I agree on the 3 branches that I see when I open the website.

Science is not a standalone category. In fact science is directly connected to mathematics which is directly connected to philosophy (through logic for example)

We might argue that also art is an extension of philosophy (e.g. finding objective or subjective beauty).

Probably Claude doesn't agree with this definition.

WillAdams5• 2 years ago

Making a note to try this when it's not slashdotted (hackernewsed?).

This sort of thing is _very_ interesting to me, and I rather desperately want something like to this tied to listings of books.

I would like to read more diversely --- at one time I was trying to read one book from each LoC division, starting at the top/broadest (so A--Z), then iterating down, but this got to be exhausting because it was difficult to determine which book to read.

A later effort was to read biographies of famous people to my children in chronological order as they were growing up --- dry run was the very simple set of U.S. Presidents --- but again researching and ordering was a big problem.

So, my hopes for this are that it includes footnotes/references/links to supporting material (perhaps affiliate links on Amazon would be one way to fund things?) and that it is possible to click through to find information on specific technical topics as well as general explanations.

anon01201214• 2 years ago

Thanks. I had tried that but the AI keeps inventing false books or providing fake URLs. When the AI will be proper I will include that feature, for sure!

anon01201214• 2 years ago

Good idea mate I'll probably include a Amazon "search list" for books, and a video "search list" for Youtube, ect... Might be cool. If I try to provide direct links I get a lot of false results but I didn't think of adding web searches themselves.

(There was a feature to generate dissertations on whatever topic but I had to turn it off because I believe it was abused and that cost a lot of credits. I'll try to add it more securely very soon.)

I received nice proposals already, which should improve the service significantly in the coming days. The goal is to entertain and educate, and as free as we can! haha, modestly. Thank you again for everything!

yencabulator2• 2 years ago

Well, since you said Kung fu, I started at martial arts and 5 clicks in it's telling me about the self defense applications of swinging from chandeliers. This is yet another pile of LLM word vomit.

One innovative approach involves using ceiling fixtures to gain leverage and mobility. This concept can be particularly beneficial in scenarios where traditional movement options are restricted.

...

Utilizing ceiling fixtures for movement in self-defense is an innovative method that capitalizes on environmental elements to enhance escape techniques. By integrating body mechanics with strategic use of surroundings, individuals can increase their chances of successfully evading threats in confined spaces. Always prioritize safety and practice these techniques to ensure readiness in critical situations.

I'm working on a new design for a site I run just for fun.

It's a simple site for streaming local radios from my city, Mendoza (Argentina): https://www.radiosdemendoza.com.ar

It was built with WordPress, and the new theme is using Tailwind and AlpineJS. I hadn’t used AlpineJS before, so this project was a great way to experiment with it.

I don't have any monetization on it, and I'm not sure if I'll pursue that for this site.

Next up, I plan to build a Chrome extension. I have limited experience with that, so it should be a fun challenge.

is_true3• 2 years ago

Maybe you can try https://wxt.dev/ or plasmo for the extensions

Do you know if there's a way to get info about programming (show names and schedule) from the streams?

yeahsure2• 2 years ago

Yes, I've been considering both options! WXT seems to fit my use case better at the moment, so I might give it a try.

As for stream names, I’ve looked into it as well, but from the limited research I’ve done, it seems like only paid services are available.

I doubt there's a way to get the radios' programming since these are mostly small radios with very basic websites and online presence. Best I can get is an MP3/AAC stream and that's about it.

https://synthql.dev: An alternative to PostgREST focused on the React-Node-PG stack. Main advantage right now is it gives you end to end type safety: you can write type-safe queries straight from your component that directly access your database.

Why SynthQL? My experience working for +10 years on enterprise SaaS is that a quite often you just want a database and a way to fetch data from it. Backends will quite often get in the way adding abstractions and layers upon layers of transformation between DB objects to domain objects to DTOs.

If you ever feel like you just want to talk to the database directly, give SynthQL a try :)

Hey HN! I'm working on Voop - a b2b phone network, leveraging eSIM & web-based UI we're turning company mobile connectivity into a SaaS.

Launching later this year in the UK and US next year, can't wait to get it off the ground.

One early achievement was buying voop.com - a very nice man in Arizona had held it since the 90s, and despite being retracted on whois, i worked out how to contact him via his custom ssl certificate on the empty holding site parked at the root domain. After a few emails and follow ups to get a response, I bought it for a not-cheap-but-not-bank-breaking amount.

Working on my lisp interpreter and freestanding programming system. I've more or less finished my ELF patcher and am working on the loader/linker that will form the basis of the foreign function interface of the language. This also laid down the ground work for working with binary structures from within lisp.

I'm also studying electronics and trying to learn circuit and PCB design. I want to buy an uconsole and make boards for it. I contacted the uconsole's power management IC manufacturer and they actually sent me some GPLv2 Linux drivers! I intend to clean it up and port the features to the existing kernel driver so I can upstream it.

Working on a new PaaS called Molnett (https://molnett.com/). Trying to replicate the development productivity you might have at larger tech companies like Google, Spotify and more.

Kind of struggling to wrap my mind around how we can avoid having EBS-style network disks as part of our product offering. We are convinced that it's a operational nightmare to maintain and it's better to provide other tools to achieve the same results. For example, instead of running Postgres on EBS or local disks, we use Neon to run it on top of S3!

I built a simple teleprompter web app to help record talking head videos with the front camera of my MacBook this week.

Link: https://camprompter.app

The insight is that if you read text from a tiny enough box right below the front camera on the MacBook, it appears as if you're talking to the camera.

Boom! Easy Eye Contact With Camera.

I scrunched up the Notion app and placed it as well as I could in the safe area to test it out for a couple of videos, but then I just wrote a web app because it seemed like the next logical step.

Once you paste the script and hit play... you can only see the text in the safe area so your eyes don't wander.

Fire up PhotoBooth and try it out!

PS: Press F for fullscreen.

Oh, wonderfully simple, might use it for recording voiceovers. Might be useful to add some kind of syntax for pauses, like a blank line between paragraphs.

yencabulator2• 2 years ago

Real teleprompters have a person feeding the text at the perfect rate, for pauses, and so on. It'd be an interesting experiment to feed the audio to Whisper or such, roughly match it to the text shown, and control speed based on that.

I'm working on a library and accompanying notebooks to process secondary school exam results (UK). My father has been doing this for years for his trust and has a fantastic spreadsheet that spits out loads of data for each school.

I've recently taken a new job working closely with some data scientists so wanted to skill up a little. So far I've got an elixir library which can calculate Attainment 8 and Progress 8. They're formulas provided by the DfE to understand individual student progress, and the schools ability to progress students.

It's just a bit of fun, and is letting me experiment with some of the various elixir data libraries and livebook. At the end of it, his trust is going to plug in some anonymous data and see if they can get more insights than this mega spreadsheet.

It's also nice to be doing a side project which isn't aimed at being a business.

The goals are:

- Develop an engine that's efficient enough to use in simulations (for training AI agents or analyzing the game). - Still emit events that can be used to visualize the current state of the game when real people are playing. - Create primitives that are easy to distribute across a network for remote players/agents.

We are building a hybrid aircraft to connect cities with high speed door-to-door transportation, without train/airport infrastructure.

It’s a powered 55-seater auto gyro - an electric helicopter during take-off and landing and a conventional turboprop regional “plane” during flight. We are at a “works on paper, let’s start prototyping” phase: basic assumptions are verified by people from industry, a development plan is in place.

My co-founder is an experienced high-power electric propulsion engineer and he’s currently developing our power train. I am in charge of the business/operations/relationships side. We are currently looking for a third co-founder to lead aircraft design.

withinboredom4• 2 years ago

an electric helicopter during take-off and landing

Surely this would make it significantly heavier? Wouldn't traditional fuel do better in terms of weight (and reliability)?

high speed door-to-door transportation, without train/airport infrastructure.

Is this meant for rural transport? Looking around my urban landscape, there isn't really a place to land something like this.

IliaLitviak7• 2 years ago

When thinking about take-off/landing you have to take into account the powertrain, fuel, noise, power-to-weight ratio e.t.c. With modern electric motors, batteries, BMS’ e.t.c. we are at a point where system weight is comparable (the battery is relatively small, motors are quite light and powerful), but all the other things - noise, efficiency, time between overhauls e.t.c. is much-much better.

Long-term vision is to build-out a network connecting large metropolitan centers to smaller places, unlocking swaths of real estate. You can live in Albany and fly to Manhattan/Boston/Syracuse in 30 minutes whenever you need to report to office/go to a concert/visit a non-emergency doctor’s appointment. Vertiport can be located on a floating pier, on the roof of an existing transportation hub, on a plot adjacent to a bus/tram terminal e.t.c.

skp19953• 2 years ago

We are working on https://aide.dev/ an editor forked from VSCode which allows you to utilize LLMs to speed up coding.

Our approach is a bit different since unlike making a better copilot or a chat experience we are building workflows which encourage engineers to work alongside AI and not just offload tasks to AI.

3np2• 2 years ago

Is there some technical limitation that forced you to make Aide as a fork, rather than a VSCode extension?

skp19953• 2 years ago

oh I could write a book on this lol, lots of limitations. One of the core reasons being: extensions by design are super limited in the functionality they can provide.

We did have an extension which worked okay while we were still learning the ropes but after 2 months developing it we realized that we didn't have access to many of the APIs which we wanted to tinker with or change the UX dynamically!

This made us look for 2 options: - either move out of the editor and become a cloud blackbox AI engineer (not a big fan, I don't want to spend my time just reviewing code) - or own the editor where people code

We chose the editor route and didn't look back after. Over that time we have changed the UX of the editor completely can better play into the APIs which are hidden in VSCode and really build something which I personally could use daily :)

Unsurprisingly, I don’t see many hardware projects here.

If anyone’s looking to share their story, I’d recommend IndieHackers, but for hardware-focused startups/projects, check out howtoware.co. (I’m not affiliated with the site’s owner in any way, but I really like the concept and want to help spread the word to my fellow hardwarers).

detourdog• 2 years ago

My hardware project is the 100 year computer. I believe the next phase of computing will be focused on maintainability and longevity. This is different from the development phase of computing that currently surrounds us.

The next wave of interesting hardware development will be focused on form factor. Devices of the future could be any shape or size.

The first version of this device I have completed but not fully documented is an 8 unit mixed use apartment building. I converted each of the 7 classrooms into studio apartment the 8th unit is my development studio.

How can a building be a computer? My perspective holds that a building is a machine that needs a differential engine to optimize the resource usage of the occupants. This perspective with the idea that some circuits should larger not smaller to aid operational understanding.

The building is done enough and I need a break so I think my next form factor will be mobile sensor network and focused on individuals and small groups.

I think developing for a sailboat will be a good complement to the building. The both serve the same purpose but one is extremely resource constrained and in a harsh environment.

Currently identifying all the current sailboat tech for a refit. The devices I’m looking at range from RADAR to sine wave inverters. A very rich tech environment. Looking forward the fall.

this example seems to simple. if i write that, why would i not write the invitation myself?

ok, i get it, it lets me avoid having to address the person directly, especially for people who are insecure or just overthink what to write, but is this really healthy?

where will it end? using AI to write love letters?

on the other hand, you could leave out the email sending feature (and this avoid any spam problems) and just send the generated text as a reply that i can then forward.

a generic email interface to send AI prompts sounds useful. encouraging people to write personal emails using AI not so much.

I (along with a friend) am working on an Elixir-based built-in error reporting and tracking solution: https://github.com/elixir-error-tracker/error-tracker

I wrote a post explaining the reasons for building this when we already have multiple third-party SaaS providers: https://crbelaus.com/2024/07/31/built-in-elixir-error-report...

It boils down to simplicity. While error reporting is extremely valuable for most projects, it is absent from many. The most common reason is that this requires entering SaaS territory. Most solutions are provided by third-parties that require you to subscribe and pay for the privilege of tracking your errors. Cost is the main noticeable downside. Data protection (GDPR, HIPAA, etc) is another.

The Elixir community is providing great feedback and it was covered both in a YouTube video (https://youtu.be/TNmSVjGyZx0?si=yd6kOwa2ZpxUyFad) and a Podcast (https://podcast.thinkingelixir.com/215).

I am working on an app for creating stories with illustrations in a revealjs slide deck.

The idea is that a user would handwrite or type the first sentence of a story they want to write. This sentence would be used by llama 3.1 as a prompt to make a short story. Then the story is fed to stable diffusion to create image illustrations. Finally, all of it is combined into a slide deck that users can see in the app and also download if they want.

I am using Shiny and Quarto for this project.

Working on an audio watermarking system.

I've got the API ready, which requires 2 main values: - The original file ( which can be sent as a file, or hosted internally and requested using an ID ) - The data that needs to be printed into the audio file.

The API will return a watermarked version of the audio file that you can use later to extract the same data you sent before.

It's currently being tested on a production website, will wait for feedback, improve, and create an actual service out of the API.

Hello everyone!

Not sure if I caught the train but still. My name is Max, a software developer based in Central Europe, and I'm working on my course "Building Command-Line Interface App from Scratch in Go" (this is a working title).

In this course I want to teach how to write CLI application from scratch in Go without any external dependencies (exception: driver for DB).

This is not another one course about how to write CLI app using Cobra or any other command-line builder library. Instead, in my course you're gonna write your own Cobra-like command-line builder library (package) to build command-line interface application from scratch.

Thus, you will know how to build an API for building CLI like Cobra and you can use it later on for your future projects. I will also talk about Command-Line Interface Guidelines showing how to make powerful, useful and easy-to-use command-line application which you can use every day in your workflow.

The course is still work in progress and I don't even have a web page for it. But I do have my newsletter where I share best resources about Go. By subscribing to this newsletter you will be notified once course is ready to launch. Also, everyone who's subscribed to my newsletter and will be in first batch to buy a course gets a 50% discount.

So, if you are interested in this kind of stuff join the waitlist for course in my newsletter on https://kovalevsky.io

P.S. I also have daily base newsletter about Go - Daily Golang. If you subscribe to this newsletter you will also be notified once course is ready to launch you and will get 50% discount to buy the course - https://kovalevsky.io/daily-golang.

Goodreads doesn't let you sort books by rating so making a tool that does:

book-filter.com

imglorp• 2 years ago

Goodreads is Amazon so its ratings are suspect, like everything else on Amazon.

It would make a ton of sense to have a third party rating and review site with some kind of dependable reputation for posters. You could still affiliate link to books for site revenue.

I'm trying up standup comedy this summer -- open mics for now.

I thought it would be absolutely terrifying to be in front of a bunch of strangers and try to make them laugh, but it turns out if you're prepared, it's not that hard. Open mic crowds are benevolent and don't expect you to be the next Richard Pryor or George Carlin anyway, and I don't "engage" the public at all; I just tell my jokes.

I try to come up with new material each time so there's some work to do, but it's fun.

fruit_snack• 2 years ago

If it doesn’t psych you out too much, trying to engage with the crowd maybe once per set or every other set could be a good way to force the habit and make it easier over time.

Not that it’s necessary for all styles, but when I’ve been to comedy shows in the past the people who are able to deal with the crowd really well are always the most impressive to me :)

malshe• 2 years ago

Good luck! I am happy to know that you don’t do crowd work, which has become fashionable now. I remember Big Jay Oakerson’s roast where someone pointed out that crowd work is what you do when you don’t have any material :)

Crowd work almost always comes down to race or profession of the audience. It can be funny only in so many ways.

I have a few projects laying around. But currently I am working on an iptv player for Android. I learned about Jetpack and found it fascinating than the xml based old process. So I started playing around and learning Android development. And lo and behold, I ended up with a more than mvp IPTv player. Now I am considering if I should be putting it as open source software, or maybe publish it to the Google store. I am considering a Google Tv counterpart where you can share data between instances on the same network. That's one of a huge pain point to input data on the tv.

Any ideas to implement?

rudasn3• 2 years ago

I'm experimenting to figure out the simplest setup possible that allows me to expose an internal web service (eg localhost:3000) to the public Internet (eg app.example.com).

A million ways to do this, of course, but I'm focused on using wireguard so that eg only my wireguard peers can get access to my local service, and for internal traffic (ie vpn).

At the moment I'm settling on having a simple script that I can run on a host alongside wireguard. The script will function like `wg-quick`, parsing a wireguard config file and handilng the routing stuff behind the scenes, and returning a cleaned up config to be passed to `wg`.

Ideally, the wireguard configs could be generated by some other tool or service, like https://wirehub.org, and automatically fetched and applied to the running wg interface.

So, a one liner on a server with a public IP and the services exposed by your wireguard peers can be accessed via a custom domain name while still respecting internal wireguard routing rules (based on AllowedIPs).

If anyone finds this interesting and wants to chat about it, I would love to! My contact info is in my profile.

hyperbolablabla• 2 years ago

This is what ngrok does right? I'm really interested in how this works, I've never looked into it before. Presumably it requires some kind of dynamic DNS updates if you don't have a static IP?

rudasn3• 2 years ago

ngrok, localtunnel, pyjamas, the list is endless..

Yeah, many ways to do it, one is running your own DNS server and have wireguard connections use that DNS server.

I want to avoid having DNS issues, so I'm thinking more like this:

1. DNS CNAME *.internal.example.com 123.23.45.67

2. On 123.23.45.67, run wg.

3. On 123.23.45.67 , run nginx. nginx must be in the same network to do geo blocking on Wireguard peer addressess.

4. Create one nginx server config per service to map domain names to upstream servers. Use variables for upstream servers, allow nginx to start even if upstreams unreachable. Add internal locations for custom errors (Forbidden, Unreachable, etc).

5. When connecting to 123.23.45.67 via Wireguard (ie, Peer Endpoint = 123.23.45.67), ensure 123.23.45.67 is in the range defined by Peer AllowedIPs.

_bramses2• 2 years ago

A few months back, I posted an essay here about how I think we are entering an age where the personal library will become an asset class unto itself [1]. This is due to a combination of the advent of semantic search and the revival of personal knowledge management in the deluge of our age.

As such, I’ve been working on the software to bring this vision to life, which is called Your Commonbase (a portmanteau of Commonplace Book and Vector Database).

In short, the purpose of the work is to create a data structure that works the way humans store, retrieve, and share information. By making these three elements as close to zero stress as possible, you catalyze creativity through remixing and augmentation of memories. My hypothesis is a lifetime building a Commonbase creates an idiosyncratic system, filled with the interpretations of an individual or a group. This individualized structure then creates demand that others want. I.e, a curation of all of the books you have read, organized by the marginalia you have added to them. This is a system people would pay for, and also a system that becomes more valuable over time.

I’ve been “working in public” by posting updates on my site [2], and am just beginning a small waitlist alpha testing phase (email me if you want in!)

tenahu• 2 years ago

This sounds interesting, but I do not totally understand your description. Could you explain further what you are building?

_bramses2• 2 years ago

Sure!

The problem with existing knowledge management systems is that they all eventually become victim to scale the operator can no longer manage.

Consider two scenarios:

Scenario 1:

You have a chaotic system of notes, dispersed throughout random pieces of paper and digital notes on your phone and computer. You have a relatively easy go of it when saving new notes (its as simple as pressing "New Note" or pulling out a new sheet of paper), but as you add more notes to your system it becomes harder and harder to find a particular piece of information. The cost of adding stays the same, but searching goes up and up. Scenario 1 causes us to eventually succumb to chaos.

Scenario 2:

You have an extremely rigid system of tag management, headings, sub-headings, sub-subheadings and sub-sub-subheadings. This taxonomy makes it easier to find information...at first. The problem with these systems is that they require a ton of manual maintenance, and they also make it easy to find certain "classes" of information, but fail at geo locating others. Much more perniciously, this scenario eventually stifles creativity as it falls prey to too much order. The cost of searching stays roughly the same, but the cost of insertion goes up and up.

(I am personally guilty of creating a system like this btw [1][2]).

Both of these systems eventually begin to become inert holders of information, as the processor (us), begin to fear them and stop working with them.

IMO, the closest technology to managing human information well in my opinion is well over two thousand years old, the commonplace book [3]. Simply put, a commonplace book is extremely resilient to chaos due to its centrality of information, but even people like John Locke had to create indexes to fully utilize them [4].

This changed recently with the advent of vector databases[5]. It turns out that commonplace book entries are the perfect form factor to benefit from an address in vector space, since entries are atomic. In simpler terms, the vector processing layer handles the order, allowing our system to "live" and assign headings/tags/etc. as it evolves. Vector databases love commonplace books as well, because many vector solutions have way too much noise as they chunk and store useless information at quite a disappointing ratio.

My system differs from current offerings because it makes no attempt to automize parts that are meant for the human, and makes no attempt at making humans do the work computers should be doing. Ergo, creating a type of symbiotic relationship.

Finally, a note on why I use the term "asset". An asset should become more valuable over time, and particularly, each individual component of the overall asset class should be worth more (e.g. $1 in a bank account of $20 is inherently less valuable than $1 in a $20MM bank account, because it grows slower). So in our scenarios above, the transmutation of information to knowledge peaks out at a logarithmic curve, subject to the scale issues I mentioned before. Old entries appear less frequently in even the most ordered systems, and when they do, it is only in one particular context. My system stores time of entry in the metadata, but since I use vector addresses, the information is accessible in many different ways (dog can be found when query == canine, fido, perro, mans best friend, etc...). An informational asset should scale linearly, and each action of create/read/update/delete should improve the health of the overall system.

There's much, much, much more I could say here, but I'll stop for now :)

I've read a ton of your writing on this topic. There is still much more, but I'm tired. You described the problem well, and if your software alleviates it, then I see the value.

I'd like to try the software if it'd available please. But I'm not sure where it is or if it's out yet. Is it the Obsidian template you linked here, or is it a separate software called Your Commonbase? Because the Obsidian vault has a different name.

I have to say that the irony is hilarious that I can't find this information in the (well written) sea of information you posted. But then of course I'm not using your solution yet!

The idea is to focus on a small community, and give back to that community. The working name is Savery. :) If this is successful, it could be launched in other places, in which case we'll likely open-source the code and have communities manage their own systems. My context is that I an a founder in a solutions company in South Africa, and I am learning to build things as a hobby to be able to best relate and discuss technical things with my software engineers.

I'm working on a workout API and native apps (iOS/Android) for Strength Level [1] as another interface for my.strengthlevel.com [2]. Strength Level helps you understand your relative strength - how strong you are for your bodyweight.

Using PHP Slim Framework, MySQL, and vanilla Swift/Java. Prioritizing reliability and efficient sync between local storage and server. Currently finalizing API endpoints and feature matching the web app. Next up is adding a subscription model.

It's challenging as:

- Users want to use the app offline which means we need to sync

- We have to match our existing features on [2] in the first version and evolve the API and database to support reliable sync

- Users want to also track their cardio too e.g. Running Level [3] and Rowing Level [4] but that will have to come out in a future version

very nice. works pretty smooth.

current pain points: the race starts immediately upon connecting. no time to prepare, so i always start in the last position because the AI drivers have a head start due to my slower reaction time.

the AI drivers are to aggressive to prevent overtaking, they will bump into the player, knocking them out of the position and causing a crash without any penalty to the AI car.

bumping into each other should cause both cars to crash, giving the player more time to recover. AI drivers should try to avoid contact however

I have been working on porting concepts of the Windows 10/11 taskbar, tray, and window management, to macos. With emphasis on simplicity, speed, and function inspired by Linux Mint MATE.

It has been a wild ride. Often frustrating but rewarding. Some days I may spend 10 hours solving an API for which app is frontmost at a given second. Sure, there's a system API for that, but it doesn't even remotely cover edge cases that exist. And many times with no answers out there on how to do something, it feels like I'm the first, so finally solving it is a great endorphin rush.

Part of the complexity is I wanted the app to be completely pluggable, kind of like Obsidian. The app communicates events to a local socket server in full duplex, which enables cross-plugin communication (but also cross-app!). Plugins access the app's JavaScript system bridge API for pubsub and system calls through a Webkit interface. Edits are hot reloaded and instant, no compile time necessary. The first time I could change my "Start" menu in real time through JavaScript/CSS was quite a feeling.

Sadly, I couldn't leverage existing tools like Tauri or Electron. They don't have adequate system bridge APIs available, and would be more work to leverage instead of less. They are too general, whereas this project only builds to macos. Therefore it can be much more complicated (and useful) by design.

I originally set out to be more productive in macos. But I've also spent time making prototypes for fun. A desktop widget system, real-time system color theme set from Spotify album art, live video desktop backgrounds from Twitch/YT, a Destiny 2 macos system theme, etc.

I plan to open source it and build a community around it one day.

I haven't used MacOS in years and have been forced to use Windows for work. I'm curious: what's great in the Windows layout that isn't in MacOS?

Coming from Hyprland and even KDE, Windows seems to be lacking a bit out of the box, but maybe I'm missing something deeper about how it all works.

zschuessler2• 2 years ago

To some degree OS productivity is subjective based on what you grew up with. Your neural pathways form around a certain way of work management and it becomes hard to change that after ten years.

I'm naturally biased then to early Windows and MATE-esque environments. And, it's worth noting that I despise Win11 overall, so a better comparison is indeed Linux Mint MATE[1]. Part of the project inspiration is to never use Windows 11 again, actually!

Before I started the project I wrote down what I consider productivity boosters for me:

1. Fast context switching between open apps and windows, natively. All open apps are in front of me by way of the taskbar, always, and never hidden. I never have to think about where to find my immediate work. I can group apps, pin them, and create custom behavior for them.

2. System tray apps for things that you interact with often, but aren't necessarily immediately working on. Macos has something similar but it isn't really pluggable or widely used yet, and nowhere near as customizable. With Win10 I can add, remove, or hide system tray apps based on how I use my workstation best.

3. Optimized Start Menu. I press a button, I get access to things I've favorited, recent apps/files, and categories of apps I use often. It is highly customizable in Win10, while I struggle to have something as efficient in macos (even though macos global search is wonderful!).

I feel like the old UX rule of "don't make me think" applies heavily here. The macos app dock is a great example of this. You're forced to think about what you want to do with 10-20+ options glaring at you. Disabling the dock is the first thing I do on a new Mac ;)

Lastly, Win10 lets me customize my system to a high degree as my needs change. I just don't get that with macos, nor have I found apps that hit the mark for me.

I'm curious about your own experiences if you care to share :-)

A database that basically acts like a modern day “virus scanner” for deep fakes. I believe that virus, malware and such that trick people into handing out information- making false decisions as we have seen with companies would be better suited if they had something like a heuristic threat score assigned to them. Yes we have websites that can tell us but it’s not the same as a virus or malware scanner. I think we need to add it to a database. Block those sites to protect consumers, companies so they don’t make bad choices. Just like in malware we see if a signature , deep fakes from bad actors also have signatures. It’s so many things. From signal- coding- so I was working on that. Maybe foolish or a waste of time. But I am going with to. Was playing with app development for cars to protect data. But might be a push against Nissan- Ford- Chevrolet-Kia- etc who like to steal data to make money off it. They control the interface. No VPN are allowed and no encryption allowed on infotainment system. So you have to do work around to keep your data out of their hands. That’s all.

2) You listen and read and try to understand the meaning with the help of translations and the definitions in context of the words in the sentence. (You can click each word to get a definition in context)

3) Over time you mark words as known

That's basically it. You learn with context using content you are interested in. I'm working on adding a SRS to the app and a feature to improve your pronunciation using the language shadowing technique.

And as mentioned, building native iOS and Android apps.

https://blr.today - Working on an open-source stack to curate events happening in Bangalore. It curates events from multiple sources, cleans them up, then curates them further by tagging them nicely, and making all event data available as calendars you can subscribe to.

Decided on a GPL/AGPL/ODBL license for the scraper/website/dataset. https://blr.today/license

My Core-thesis[0] on why I think this is worth building:

1. The vast majority of events in aggregator websites are low-quality, and often filled with spam. The aggregators make money by listing lots of events.

2. Small venues hosting cool events will not always publicize them on the aggregator platforms.

3. The best UX for event discovery is your existing calendar app.

4. Events are highly structured data - but this is often not captured.

I've been wanting to build this for almost 6 years now, finally getting around to it.

I updated my ideas repo last week with some more of my ideas.

If any of these sounds like fun, take a look:

* A physical variable fuzzy clock

* A curl impersonation proxy

* A Whisper UX Design Pattern

* Mobile App Traffic RE Platform

* One-Page (RSVP|EventHosting) Platform on Edge Compute

* Price Index for Indian Grocery Websites

I've recently been working on SparkShell: https://sparkshell.dev

It's an online development platform similar to other things like Replit, but it's mainly for static site hosting. You can create projects and make custom subdomains for them. You can add libraries to your project in a click of a button, so you don't have to add scripts or CSS files to every single file of yours. I've recently been doing a lot of work on it and I hope to launch it pretty soon.

I am developing a Pythonic alternative to ArgoCD and FluxCD that uses no CRDs or in-cluster controllers for continuous delivery of applications to Kubernetes clusters

jokoon3• 2 years ago

Still slacking before I decide to work on that character controller for my minimalist, low-poly counter strike clone, with Godot.

I properly animated a model with blender, and am able to move the parts I want accordingly. It was not easy but I made it.

I also managed to implement the recoil algorithm I want.

I modeled guns.

I will probably struggle to implement server reconciliation to mitigate lag, I found 2 modules that does it, one in C++, one in gdscript.

Obviously the gdscript one is slower, but it's hard to know how much slower, since obviously a game like counter strike is very fast paced.

I also want to implement a panini/wide angle camera, also found a module for it.

Moving slow with bad mental health and anxiety, but having fun.

I have been recently thinking about the NP-complete class of problems particularly the knapsack problem (it is easy to understand and attack). And I think it is really solvable in polynomial time. I actually tried and posted my solution here. https://news.ycombinator.com/item?id=41341608 a bit of feedback would be really helpful.

mbmjertan3• 2 years ago

Your solution is not an exact solution to the knapsack problem, but a (relatively well known) greedy heuristic approach towards the problem. It is a good approach towards a solution, but the knapsack problem isn’t as trivial as it seems.

For a counterexample, imagine you have a ton of items that have a weight of 10^-20 and value of 1, and a single item that has the weight of whatever is the capacity of the knapsack (so it’s only thing that fits if it’s inserted to the knapsack) and the value of +infinity.

All items have their cost ≈ 0, so whether you fit all of the “light but valueless” items or the single “heavy but extremely valuable” item depends on how you sort when costs are equal.

An improved heuristic would take the value into account more than just having it as a factor, but it’s not easy to design.

I would recommend finding an open course on algorithm design and analysis and going through the lessons while trying to extrapolate approaches to problems instead of just solutions to them.

that is rather an extreme example. i do not see the how it affects the validity of the solution in most cases.

I would recommend finding an open course on algorithm design and analysis and going through the lessons while trying to extrapolate approaches to problems instead of just solutions to them.

implementing solutions is the concrete result of extrapolating approaches and choosing the best one to implement. and that is the pragmatic approach.

Tried to rewrite the Javascript 3D library three.js to make it smaller and more specialized for my game. Today I’m ending that and instead starting to write a 3D engine from scratch with the knowledge I learned from this rewrite process. Less object orientation and code organization, in order to get to the core of what happens in the machine (the phone/computer). There is enough complexity in the OS+browser to get through to use the device’s full power, so I at least try to remove all complexity possible from the code. Make it use less memory, download time and CPU time, and also make it go through the Javascript parser and bytecode converter as smoothly as possible. Then minimize the number of draw calls (that’s often what takes most time in the GPU) so I can render more varied graphics at the same speed (if less time is spent on sending data back and forth to the GPU, more time can be spent doing cool stuff in the shader code, I guess?).

Swain123• 2 years ago

That sounds interesting. What are you planning to do knowing the patterns? And isn't the data private?

jfil7• 2 years ago

I am making the data available for others to use for academic analysis and/or supporting legal action. The large Canadian grocers are known to price-fix and collude, and it would be interesting to see if there are any patterns in their pricing movements. (My contribution is "getting the raw data")

The data was posted publicly online on the merchants' websites.

lbrito2• 2 years ago

Ooo, that is interesting. There was a website that kind of did that, but you could only compare single items at any given time, which kind of defeats the purpose (if it is to save money).

Ideallly I'd like to see something like a personal basket where you can add your recurring stuff (eggs, milk, etc) and compare the subtotal among local grocers. Bonus points if you add in value of store points + credit card bonuses (which might be significant, like 5% for Amex cobalt at a market coded as a grocer VS 1% for non grocer code like Walmart).

jfil7• 2 years ago

I'd like to do something similar to the "personal basket" as a way of comparing "value" at different vendors. Thinking of using $/100g of common sandwich ingredients to demonstrate how much "making the same sandwich" at different stores would cost you. I'm not aiming to use this data for a product/commercial endeavour, though.

Ideas:

- A "vibe shift" has occurred at work. Separately, my own thoughts have been more unkind/uncharitable towards others. Recently I realized that the two are connected. Isn't it funny how the vibe-shift trickled down to affect my own mindset without me even noticing?

- I think that Google is going to fall apart soon. Before they do, they'll cut money-losing boondoggles like, oh, Google Maps, Google Books, Google Groups... Who will step in to save all that data? And what does a post-Google world look like in general, anyways?

- AI is incapable of the kind of impact that is being promised. But we are still going to have a period of ~2 years until corporations realize it (it sounds like AI companies will run out of cash at that point). Until then, we're going to have a lot of layoffs because Mike-the-MBA thinks AI can do people's jobs. What should normal people do? Sit tight and sit out the game for 2 years until things stabilize?

- All of the above is part of a crisis of meaning that people - and esp. tech workers - are having. There's an enormous opportunity for Government jobs to become prestigious again. It used to be a mark of pride to work for the Government. You don't need to burn out and become a woodworker to "do real things": your local city government has plenty of "real things" for you to do in a real community.

I've been working on an exciting project called DataSignal, where I'm developing a sophisticated Named Entity Recognition (NER) and enrichment system. This system is designed to identify and extract key entities from blocks of text, such as names, locations, or organizations, and then provide rich contextual information about them. The goal is to transform raw text into meaningful data that users can easily understand and leverage in various applications.

The real magic of DataSignal lies in how it delivers this contextual information. It can be seamlessly integrated into your workflow through a browser plugin, which instantly highlights and explains entities as you browse the web. For developers, DataSignal can be embedded directly into a webpage via JavaScript, enhancing the content on the page with dynamic insights. Additionally, it offers a REST API, allowing for flexible and customizable integration into other software systems.

Whether you're a developer looking to enhance your application with smart text analysis or someone who wants to streamline research and data gathering, DataSignal is poised to bring a new level of insight and efficiency to text analysis. This project aims to make complex data more accessible and actionable, transforming how we interact with and interpret information.

I'm finally frustrated enough by the state of coding that I'm developing my own coding environment and language. The leading question is: What if UI was first-class while programming?

Happy to elaborate if anyone is interested, I will also write about it on my blog (https://watwa.re) at some point

WillAdams5• 2 years ago

Which environments/systems have you tried?

A search of your site doesn't have a match for "Literate Programming" --- I've found it a benison when developing, esp. in that it allows me to review code which already exists, and to create a structural index while writing which allows a quick/easy check if a given module already exists in a context where it should --- managed to make a system for this w/ a bit of help from generous folks on tex.stackexchange:

https://github.com/WillAdams/gcodepreview/blob/main/literati...

https://github.com/WillAdams/gcodepreview/blob/main/gcodepre...

and as the readme shows, I am fascinated by the idea of visualization of code:

https://raw.githubusercontent.com/WillAdams/gcodepreview/mai...

(probably because of reading Herman Hesse's _The Glass Bead Game_ (originally published as _Magister Ludi_)

I'd give a lot to have a programming system for METAPOST/FONT (or some other graphical language) which both allowed drawing in the view and then editing the textual representation of the code causing the view to update (yes, I should use http://tikzedt.org/ )

gr__or3• 2 years ago

Pardon the delayed response, I'm not sure if this will still reach you but I'll type it nonetheless.

I unfortunately am not very fast at reading Tex so I could not quite grasp it. My main touch points with literate programming were probably iPython Notebooks and ObservableHQ. I like interspersing code with (rich) text, and starting with a top-down view of a codebase is imo also the way to go.

I'm less sure about the macro bits, I have yet to see a language where it makes for sane means of abstraction. It certainly solves for a hole in our meta-programming design space, but I don't think we've found the right hammer for that nail yet.

From the ones I know of, Pharo is probably closest to my vision, though it is still very far from it, being brutally OOP (the obtuse kind, for me at least) and it still puts a wall between code and visualization. A wall which I intend to tear down.

Thanks for the Hesse recommendation, first time I'm getting one in my native german on this site.

Uses the scenedetect Python library to locate scene breaks and then uses perceptual hashing to find points for alignment. Also will include a small webapp to debug and adjust things manually in difficult cases.

https://youtu.be/P_4mhMB-0L8

-Uses WASM under the hood (blazingly fast) -Exportable into a simple format for desktop, mobile or web use - @htmx_org integration included -Pluggable into any existing front-end or back-end (React or Laravel, etc...)

For now, the work of re-creating the layout lies on programming but I will start building plugins so that it lessens or removes that need.

I’ve been working on Don’t Double Book Me (https://dontdoublebookme.com) the past few weeks out of frustration with keeping my personal and work Google Calendars in sync.

Previously used Reclaim but found $10 a month to keep 2 calendars in sync was excessive and the software was increasingly becoming more team oriented, no longer for individuals. Felt like I was paying for a product and also the product. I just needed to keep 2 calendars in sync, not smart meetings, analytics, integrations, etc. ideally I set it up and forget about it.

I really needed a way to sync my calendars privately, without all the extras. Now that Dropbox has purchased Reclaim, it's even more important I feel like my calendars are not spied on. I knew I could provide a similar service.

Here’s what makes me excited about it as a user:

Affordable: Just $20/year with a 7-day free trial. Cancel at any time for a pro-rated refund.

Privacy First: No need to store events on a servers enabling unlimited calendar syncs.

Working Hours: Adaptive feature that adjusts if an event falls outside your specified working hours.

Round Event Times: Opt to round event start and end times to the nearest 15 or 30 minutes for cleaner scheduling.

Invitations: Block time between calendars when you receive a meeting invitation that you haven't responded to yet. Decline it? The time block on your other calendar is removed.

My plan is to keep it small and focused, while also listening to user feedback for how you'd like to manage your personal and work calendars more efficiently.

Thanks for checking out my new project.

asdf69694• 2 years ago

Don't Double Book Me isn't some crazy startup idea that needs funding, I am not shooting for the moon with this. Feature development was basically done in a few weekends and I like that it solves a single problem well. There is definitely a market for people who need a tool like this. Look at Reclaim, Calendly, Clockwise, CalendarBridge, OneCal, etc, which have successfully tapped into this market but are focused on selling to teams.

I designed it for individuals balancing personal and professional commitments. I work somewhere with a heavy meeting culture, nothing I can really do about that. I found myself double booked often with personal commitments I had. Consider a scenario where you need to attend your child’s school play, but you forgot to also block off time on your work calendar, now your colleagues think you’re free and invite you to something. You've been double booked.

Events outside your working hours aren’t synced, protecting your personal time and privacy. The default setting is to create events on a destination calendar with the summary explicitly being "Busy" without any other information, but you can change it so it mirrors the event details should you choose.

Rendello5• 2 years ago

I've been building a web extension for an Inuit language (ᐃᓄᒃᑎᑐᑦ ᖃᓂᐅᔮᖅᐸᐃᑦ).

Most Inuit in Canada speak Inuktitut, which is a language with long words and two different writing systems: the latin alphabet, and syllabics. Syllabics are specially adapted for Inuktitut and well-loved by the Inuit, but unfortunately can be a pain to input on a computer, so often times the more cumbersome latin alphabet is used in casual writing.

Tom Scott has an awesome video about how syllabics work[1], but breifly, the shape of the character determined its inital consonant spund, and the rotation determines its vowel sound. So ᐱ = pi, ᐳ = pu, ᐸ = pa, ᑎ = ti, ᑐ = tu, ᑕ = ta, etc. The word "Inuktitut" becomes ᐃᓄᒃᑎᑐᑦ in syllabics.

Transliterating between the two is fairly simple, but there are edge-cases around dialects and whatnot. The more interesting problem from a technical perspective is having a web extension that can detect Inuktitut on a web page (in wither writing system), and transliterate that into whatever writing system the user desires, whilst never accidentally transliterating the other text on the page ("inhabitants" could be picked up and transliterated as "ᐃᓐᕼᐊᖯᐃᑕᓐᑦᔅ", for example, even though that makes no sense).

The project is mostly using Rust via WebAssembly, which has been a lot of fun to work with and has let me do some awesome things, like avoiding heap allocation and using compile-time hashmaps to do conversions on the text. The build system has to do a lot and I eventually settled on python. Right now I'm trying to wrangle JS and the DOM (there's a lot of edge cases to deal with), and that's been difficult as it's not my wheelhouse.

Rendello5• 2 years ago

I think you may have replied to the wrong comment or misunderstood my project, it's mostly finding text from a certain language based on some (fairly simple) heuristics, then converting it from one script to another in a systematic way, with some options a user can set. I doesn't have much relevance to LLMs or game engines, unless your game has an Inuktitut translation, in which case it'd be better to transliterate ahead of time ;)

I've been learning how to use Blender. For a long time I've thought that working with things in 3D could be made simpler by having an app where your phone is a sort of 3D cursor, and e.g. for modeling you could use your phone as a sculpting knife by moving it around in the air.

So I spent some time trying to make an app that allows you to do that, but can't shake the thought that such an app would work better as a Blender addon/plugin rather a standalone app. And I also am trying to figure out how people work with 3D currently, to see if such a tool would even be an improvement over existing tools.

After a long walk against myself, of about 10 months, it's nearly finished (in my native language, Spanish). It still needs a few more reviews and retouching.

I got recently unemployed after +20 years as Linux sysadmin, and my wife is now unemployed too (after +20 years in HHRR), fortunately we have still a few savings.

I dream that it will (economically) work, but most of the time I intuit there will be less than a few sales from family and friends.

Depending on how it goes, I've already the script for the second and third parts.

In parallel I'm researching different ways to generate cash flow without working for another person. I would like to avoid going to search for a job in the current market of cloud, docker and kubernetes, as I'm more a hardware/colocation guy, and 99,9% of job offers request for docker/kubernetes.

When you say "by hand" do you mean with a pen and paper rather than typing it out? If so, can you say something more about why?

als0• 2 years ago

He says he uses Vim, which is on the computer.

txutxu3• 2 years ago

Sorry, edited to clarify. I mean avoiding AI.

Mainly I use vim. But yes, sometimes I also use a traditional notepad with a soft ink pen. To avoid myself some screen time, because I'm out of home, or just to make some use of it.

I think the output flow is about the same using pen and paper than using vim, at least for me.

The original "By hand" did mean "without AI help/inspiration".

I've been working on https://65words.com by myself for 6 months.

65 Words is an anonymous challenge to write 65+ words daily in the language you're learning.

The real focus isn't just on improving your writing but on having the opportunity to think about how you'd express something without the pressure of the moment.

There's no hidden science behind choosing 65 words. I found it’s achievable even on a very busy day.

The goal is to help learners practice daily and build confidence through consistent effort.

I’m writing a series on how to understand golang if you’re an experienced TypeScript developer.

I’ve worked with several teams now who wanted to adopt Go for the backend, but the team’s only extensive type system experience is in TypeScript. They tended to hit very similar pitfalls and want to coerce the type system to behave like what they’re familiar with, and inevitably they wound up with inflexible and error-prone architecture.

They also failed to accomplish any kind of holistic, 30,000ft view architecture because implementations were too often sent off the rails by not understanding the language deeply enough. That was often in part due to type system confusion inherent to how Go implements certain data structures (particularly slices), which leads to the sprawling repetitive Go code people dislike so much.

I did all of this too, so I feel like my insight and experience would be valuable to share. I actually wrote 90% of it last year and felt like a goof, like, ahhh what am I doing obviously everyone else figured out Go faster than I did and this writing is just telling people how incompetent I am. Haha. But then I worked on another project and the situation was exactly the same. I actually used my draft content to help the team understand how I see the problem, and how to get past the mental traps that they were in.

Fundamentally it comes down to “learn the type system/language properly”, but it’s not quite so blatant or unhelpful. One of the problems with TypeScript methodologies is that they’re so ridiculously flexible, but go is not at all in the same ways, yet they have just enough superficially in common to trick you into thinking otherwise.

So, my series essentially elucidates the similarities, differences, and what’s totally absent in Go from the bottom to the top. It’s interesting because they really are remarkably similar in some ways, which is precisely why it can trip newcomers up. Knowing why that’s a trap makes you a far, far better Go developer. Along the way it also reveals details about TypeScript that some people might not be fully aware of (at least several in the team I shared the drafts with said so), which could be helpful.

I mostly need to muster the courage to hit publish now. My confidence has taken a beating in the last year or so!

Working on the concept of Computer 2.0 idea by Andrej Karpathy.

Basically it is an AI computer. It is nothing like we have seen before.

May open source it soon. With working zero hallucination (need additional evaluations).

Works with all devices. Created a MVP, air-gapped for military use, but it can be used for anyone including businesses/consumers who need an on-prem AI computer.

It has zero lag or zero second delay in responding your questions, and does not use any third party AI cloud platform. This is critical, because some of our customers have restrictive requirements for their data and they can't have anything of their customers to be placed on these cloud platforms. (eg. OpenAI, Google, Apple).

Adding additional features including Self-Teach, Cloned Personality, the holographic UI Wear, makes calls on behalf of the user, uses voice imprinting, edit videos, autonomously, for content creators and remembers 100 years of your life. And, more.

The UI Wear uses the exotic sensors I used in military to make it light and performant unlike Apple Vision Pro. Imagine interacting with something like "Jarvis" from Ironman. Quiet similiar but much more grounded in a sense that it's simpler and logical. Also, you can take it with you to play fast action sports or play games like Dragon-Ball-Z type game with your buddies. And it lasts a day, not two hours, on a full charge.

You can interact with the Personal AI Computer without the UI Wear, but it takes you to another level of experience.

Currently, doing it solo and looking for a cofounder who has experience in large distribution, logistics, creating polished commercial hardware, etc. Even if you don't these experiences, please contact me, if you want more info, interested, and/or want to work for this startup.

I'm working on a command line billing/invoicing system. I couldn't deal with the ones I've tried (too heavy on UI, too difficult to automate stuff with).

So far I just use it for my company billing, but it's quite delightful for me: My process is to save the services we provided in CSV files (exported from time tracking in org-mode, but you could use any tool that supports exporting), then I run this over it and it creates PDF invoices, and stores all the data (which I query occasionally, e.g. for quarterly VAT payments).

Technologically it's weird, the invoice templates are written in LaTEX, and the code is in Common Lisp.

I don't think about turning it into a business, but I think I'll open source it once it's a bit less messy. For now, I just focus on implementing the features I need (about 1-2 per quarter now).

I kinda doubt it, but if anyone is interested in command line billing tools, I'd be excited to talk about it. Contact info is in my profile.

I am working on a strategy game. I call it The Lost Age Of Abundance. A multi-player, real-time war-and-economics game. It is the kind of game that most developers would typically take a turn-based approach to, but I think turn-based games are mostly boring, so in this case it is real-time. My plan is that at least 100 players can play at once, but perhaps I might be able to get that up to 1,000.

There are some unusual things about the game. To win, you have to conquer all of the land. However, no player is ever knocked out of the game. If you lose all of your land, you can simply become a guerrilla leader and engage in guerrilla warfare, in the hopes of turning your situation around. Being a guerrilla leader is difficult, but if all of the guerrilla leaders form an alliance, they might have the strength to reduce the power of whoever is winning at that moment. Every player starts off as a Noble Lord but you can become a Priest or a Communist or an Anarchist. (The Anarchists have a unique way of winning, which does not involve conquest.)

I have been working, for months, on the economics, which are very complex and I think very interesting. All prices start off randomized (within certain bands) so there are no "good units" or "bad units" only those that are under priced or over priced. There is an economic cycle that runs once every 60 seconds. It takes all purchases and turns the money spent into inflation. Specifically, the percentage of total world GDP that was spent on a particular product is the inflation rate, so if all of the players collectively spent 2% of their income buying swords, so 2% of total world GDP was spent on swords, then the price of swords goes up 2% for that minute. In this way, with players buying what is under-priced and thus driving up prices, the prices are pushed to their rational levels. Also, the inflation rate tells you something important about what other players are doing. If you notice the price of horses is going up at an alarming rate, it means one (or more) of the players is spending heavily to build a large cavalry force. The economics are entirely deterministic, based on the activity of the players, there are no random events. There are no randomly generated earthquakes or floods or NPC invasions. Every change arises from the actions of the players.

I was originally going to give the game the historical setting of the Chinese Warring States period, but then I decided to go with more of a fantasy theme. But there is nothing overtly fantasy in the game, it's simply that there are many myths, which the peasants might genuinely believe, that explain how the Empire Of Abundance was transformed into the Ruined Lands. The peasants are looking for some leader who can restore the Lost Age Of Abundance. The peasants (NPCs) will switch their loyalty to whoever they think can win. Occasionally some peasant will become a True Believer, in which case their loyalty is fixed for the rest of the game. That means even if their chosen leader is defeated and becomes a guerrilla leader, the peasant will remain loyal to them, and secretly send them small amounts of money, to help them recover.

If your peasants think you are doing a terrible job with the economy, they will emigrate to the lands of one of your enemies. You can seal the border, to stop the emigration, but the peasants treat this as tantamount to putting them in prison, so their morale will plunge. If their morale gets low enough, they will switch their loyalty away from you and to any nearby guerrilla leader.

There are 3 games in this game:

1. the military game

2. the economics game

3. the spy game

The military game and the economics game are entirely deterministic. At no point does the software "roll the dice". Combat is as deterministic as in the game of chess.

The spy game does use probability. If you torture a peasant then there is an 80% chance they will tell you the true. If you are wondering if one of your peasants has become a True Believer for one of your opponents, you can torture the peasant to get them to confess. There is an 80% chance that whatever they tell you is the truth.

I have almost zero graphics for this game, so I think it will only appeal to a limited set of people who are interested in a game with a very dynamic economics system. The point of view is basically that of a ruler sitting on their throne in their capitol -- they only hear the reports brought to them by messengers. They cannot see the economy, they can only read the reports and graphs given to them by their court scribes. Likewise, with battles. In that sense, the whole game is a bit abstract, but I hope it will appeal to some niche that wants something complex.

mikem170• 2 years ago

Your game reminds me of some ideas I've kicked around, with players being nobles of some type, and having the same point of view (receiving updates and sending orders).

In my game these player nobles would functionally act as kings/queens, governors, generals, admirals, or travelling mooches, depending on their goals and how well they are doing. The map would be broken into cites and towns arranged into territories, nothing super granular. I wanted to feature politics, where players would normally need to interact with each other, with shifting alliances, etc. A general might decide not to obey their king, perhaps planning a coup with some governors for example. Kind of like the board game Diplomacy. A king would need to coordinate tax incomes from governors, dispatch generals and admirals, expand alliances, and be wary of threats. Governors could influence trade and improve their territories, cities and towns. Generals could perhaps take on mercenary jobs, or raid. An ambitious admiral might want to take a city and move up in the world, or be happy enriching themselves in trade or pirating, etc. There would be gold and various other resources, population morale, seasons, spies, etc.

I was going to have this game be turned based, with each turn being a month of game time, and players only being able to take one turn per day of real time. The world would be one month in diameter - so that a fleet or army or inter-player message could be dispatched to anywhere in the game in a single turn. I figured that this would avoid the possible problem of players gaining an advantage by being able to coordinate outside the game, and to keep the programming as simple as possible. A minor character might not have a lot to do on any given turn. A king or queen could be a very busy person. Players might be on autopilot for some number of days if they don't log in. News in the game would travel also, so any player could hear about most of what was going on in the world. I shared your sentiment on graphics, figuring I would leave room to add those later.

I like your ideas for your in-game economy, and what you described about the effects of morale, and true believers, which I'm sure dovetails with there being priests. And it's cool you have a place for anarchists. They get a bad rap.

Be sure to do a Show HN when it's ready!

lkrubner2• 2 years ago

"The world would be one month in diameter - so that a fleet or army or inter-player message could be dispatched to anywhere in the game in a single turn."

I had a similar idea. Since my game is real-time, rather than turn based, I decided to use time for to indicate travel. There is basically no map. In that sense, it is similar to some sci-fi star games where star travel is mostly handled by "teleporting" from one star to another. Though I use time to indicate that attacking another Kingdom cannot be done instantly.

Thank you for the suggestions about Show HN. Good idea. I'll do a Show HN when it is ready.

Looking into better compression algorithms inspired by ML, LLM techniques under different constraints. For example if the receiver has a prior knowledge because future devices will have some foundational models that already understand higher level concepts like how a human looks or speaks, do we really need to send the entire recording or just the "words", "intonation" etc and reconstruct it on device.

I'm developing Weavus (https://weavus.app) as a way to take my events away from facebook. It's a social app (mobile only for now) where events are the main element and the home screen shows your upcoming events. The philosophy is no feed, no ads, no addiction, just your real social life.

The idea is also to merge in a single app many needs of events, like group chats, photo albums, expenses splitting, and I'm planning to add more. I realized groups have similar needs to events, so I added them as well (think small private groups, not massive communities).

All of this is stil very early in development and it definitely needs some more work before a Show HN, but we've found it very useful for weekends and holidays already.

Consider it an open beta, so feel free to give it a try and give me your honest feedback :)

So I have started creating a new keyboard layout based on Dvorak; but more a text generation and expansion engine, with snippets or abbreviations in vim.

Initially also on Emacs as a minor mode, the concept is to write in a shorthand of greek letters, mapped like to a Dvorak distribution, that stand there as a code, as variables or latent values, expanded upon a key combination to one of several languages: German, Hebrew or Yiddish. Text can stay code-mixed indefinitely. The greek letters are a preform, condensed by layers of translation and transliteration, a hybrid con, and the keyboard layout itself, dynamic and not static, is dual: for every greek letter in the layout correpsonds a hebrew letter or diphtong or diacritic mark etc. It is a merge and disambiguation of both Dvorak/Programmer Dvorak and Yiddish Klal.

I really don't know if it may seem useful to someone, but I've been itching writing a bit jargon in a system like this for some weeks.

Websites like TappedOut and Archidekt are great products, but as someone who plays casually and doesn't do much to keep up with releases I find assembling fun Commander decks from singles to be quite a time investment, and I'd like to see if I can focus in on that UX specifically for myself.

Although I am currently 16 and the summer vacation is coming to an end, I have made big progress during these few weeks. My mission was to build an app with the help of the Flutter framework, and I have succeeded!

The app's website is vid-note.com, if you would like to check it out. The value of the app is that one no longer has to watch endless videos but can find exactly what one needs about a certain topic within the notes that we offer. What is good to know is that most of the notes are centered around business and self-improvement for the reason that we, the founders, are interested in these topics. We understand that many would advise us to let an LLM write the notes, but for this project, we have decided to sway away from the flawed results that LLMs bring with them.

This is the first venture my business partner and I have decided to pursue, and we look forward to finding out if we must pivot or preserve. For those wondering, the app has been approved for external testing on the App Store, but we have decided not to make the jump yet, simply because we still have to handcraft a few notes ;). We predict that a release on the Play Store will soon follow. Cheers.

This isn't really very interesting or innovative compared to other comments here, but lately I've decided I want to build a home server to do a few tasks: Jellyfin server, photo server (probably using Immich which looks like a nice clone of Google Photos, where I'm almost out of space), automated device backups, etc., so I've been doing a lot of research into this. I've built computers in the past many times, but I got out of it a while ago so a lot of things have changed.

I looked into pre-built systems like Synology and QNAP, but they seem too proprietary and limited, and somewhat expensive for the hardware they have, so I decided to build my own, but trying to decide on all the HW and SW is a real task: btrfs vs ZFS, Intel vs AMD, RAID levels, etc.

Hey all! I'm working on a context-aware CMS called trilly.

The idea is fairly simple: the client app requests content and passes the context (key-value pairs) along with it. In the trilly app, the content manager sets up different variants of the content for various context field combinations, and the one that matches is returned. Context can be anything, from user role or user location to more abstract things like A/B group or user behavior. It's just data.

I have a couple of ideas on how to extend this system - realtime LLM-generated variants, or more sophisticated context fields (date/number ranges, randomness, etc.).

For now, however, I'm exploring whether this idea would be useful for someone, so thanks for all the comments.

I've been working on https://console.wut.dev/

Right now it's a collection of a few tools:

• AWS Resource Explorer - a lighter-weight version of the AWS console where everything is just a sortable/filterable/searchable table.

• Access Denied Debugger - paste an "AccessDenied" message and get back a stack-trace style UI showing all the resources involved, reason for the error (e.g., which policy is missing a permission), recent changes via CloudTrail, etc.

• AWS Organizations / SCP Viewer - generates a tree-diagram style UI showing all your AWS accounts, which policies apply to them, etc.

Still working on merging these into a cohesive application (mostly just been scratching my own itches so far). I'm trying to consider privacy/security carefully, so everything is client-side, using the AWS JavaScript SDK, and creds/data are only stored locally.

algebra-pretext• 2 years ago

This is awesome, I work at AWS and might use this when the console load times get on my last nerve and I just want to check some IAM policies. The Access Denied debugger sounds like a massive timesaver too.

Oh that’s so nice to hear! It’s quite an early alpha, but I’ve working to expand support for more resource types and details. Feedback is very welcomed.

I've been working on https://snippethive.com/ with a friend of mine.

We were both tired of asking AI for the same code again and again, so we thought, why not build something where we can instantly save code from our AI chats

The idea is to create a public library of AI-generated code that anyone can search through, find what they need, and either use it directly or customize it further.

For example, if you find a function that almost fits your needs, you can add it to your AI chat with just a click and tweak it, instead of starting from scratch.

So far we have -

1. Chrome Extension - To save your code or find what you need from the library and add it to chat. Currently only works with claude, working on making it compatible with v0 and chatgpt

2. VS code extension to find whatever you need right in there and an AI that will understand your project's context and integrate these snippets in seconds ( AI part is in progress )

3. Website to do other stuff - build your profile, rate other snippets ( which helps us to maintain quality )

Tech Stack -

- Frontend: NextJS, Tailwind, Shadcn

- Backend: Node.js, Express, MongoDB

- Extensions: TypeScript (VS Code) & React, TypeScript, Tailwind (Chrome)

A pledge is the price you’ll pay for breaking your pledge. It’s more than one second of reflection. You have to ask yourself “do i want to spend a $1 to use YouTube when i should be studying”?

I don’t have a website right now. I’m calling it FocusPledge. It’s near complete so if you’re curious you can shoot me a message or follow me on X at @harveenatwal_

I am working on https://budgetflow.cc

It is a budgeting tool that allows you to create budgets and visualize them as interactive Sankey diagrams. You can configure smart "pockets", which can automatically send excess cash or take missing cash from other pockets. It also allows you to invite other users to shared budgets, so you can use it to plan budgets with roommates or your partner. Currently I am thinking about ways to make it into a viable business, but it is still not quite there yet where it needs to be for that.

seism6• 2 years ago

It's very nice and clean and functional. Budgets are some of the most boring and universal tech ever, and I think your project is very worth continuing. Kudos for having a collaborative (if not fancy and needlessly realtime) feature from the start!

For fun (and no profits!), I built an AI-powered haiku poetry and generative visual art app. It started as a daily puzzle (https://haikudle.ai, previously shown on HN), then evolved into an authoring tool with curated daily haikus (https://HaikuGenius.ai).

To learn more about SEO, digital marketing, and other areas I hadn't explored in much depth yet, I tried bringing it to market with modest success. It's been a fun journey so far, and I’ve documented the first legs here: https://medium.com/@desmat.ca/a-genai-haiku-journey-part-1-a... and https://medium.com/@desmat.ca/a-genai-haiku-journey-part-2-f....

Removing duplicate annotations from the Kindle clippings.txt file.

I like to annotate (highlight and create notes) when I read on my Kindle, and then I take those annotations and throw them into Obsidian. The issue is that if you ever mess up a highlight or note and then delete it, it doesn't actually get removed from the Kindle clippings file. So this project will remove all of the "incorrect" clippings.

I have the de-duplication algorithm working extremely well and right now I'm working on creating the web app using python/django

Building LLM evaluation suites. Basically trying to test LLMs for privacy problems (data leakage/memorisation, PII extraction sort of thing), hallucination(RAG, summarisation etc) and security/compliance stuff(like bias/fiarness, toxicity, jailbreaks/prompt injection).

Involves a bunch of reading research papers, figuring out which ones are relevant to enterprise customers and getting our ML team to build it out. The most interesting part of this is how you present the insights of a given test to a customer in a consumable and usable format. (Ex: Just dumping a bunch of RAG hallucination metrics isn't enough but you want to figure out what are the key insights and interpretations of these metrics which could be useful to a data scientist or ML engineer)

https://www.justbeepit.com/ started as a web annotation tool that I hacked together with a friend. Now, it’s a full-fledged visual task management platform with over 2,000 users.

In 2022, I wondered what it would be like if my manager could leave comments directly on the live website for all the edits, rather than sending a bunch of screenshots and videos. That’s how I came up with the idea for a "simple" browser extension that lets you leave comments on any site, anywhere on the screen.

There were several challenges along the way:

Attaching Comments to the Correct HTML Element: I initially struggled with ensuring comments were attached to the right element, as relying on X/Y coordinates would not be responsive. Now, I use a combination of element IDs, classes, outer HTML, and attributes. This approach works correctly 95% of the time. Do you know of any other methods to find the correct element in the DOM?

No Third-Party Libraries: Extension development only allows pure HTML, CSS, and JS, with no external scripts from CDNs. Building a text editor from scratch was one of the most challenging parts.

Real-Time Functionality: Keeping the extension's background page active was tough because it deactivates when not in use, making it almost impossible to maintain a socket connection. I wrote code to wake up the background page and reconnect the socket whenever it goes to sleep.

I stopped all my freelance projects, and now three other people and I work on this tool full-time. We recently became #1 on Product Hunt: JustBeepIt.com

There are still many issues we're working on, such as using it with iFrames or inside scrollable objects, but we're tackling these challenges one by one.

I’m a few days late to comment here but I’ve been creating metal furniture again this summer. Mostly tables, end tables, night stands, some benches and stools. It’s a hobby thing and my house is getting quite full, but I’ve also had a few commissioned pieces.

I like to mix different materials into the designs I cook up. For the tops I use cut stone which is prohibitively expensive for most hobby stuff but works really well for commission work because of all the different types (marble, granite, composite) and styles/ colors you can get. It gives it a very high end look and feel when combined with a sturdy metal frame. I’m also really into 3D printing so I try to incorporate that into the work as well. Using different pattern schemes to make inserts and accent pieces.

I’ve also experimented with incorporating IKEA furniture pieces into metal frames because I love the idea of doing modular furniture that can be swapped out for different colors and textures. I use the same idea for my 3D printed work.

I love the creativity and flexibility this gives me and my welding skills have ramped up significantly. It’s been years since I welded seriously and I really lost the techniques so getting that confidence back is great. I’ve been approached to do some big 5-6 figure home design jobs through the connections I’ve made acquiring stone pieces but I’ve only consulted on advice. I still feel a bit insecure about putting myself out there in structural work. I see how successful different design firms locally are building this stuff for tech companies and I’d love to eventually have my work featured like that but taking it slow for now.

Working on 8 inch Cassegrain telescope F 30-40 with small secondary and optimized for planetary observations.

But in order to get there, I need to rework a couple of mirror grinding machines in the club according to specs by the professional optician teaching us.

This means building the right set of mechanical thingies to safely hold glass and tools from 6 to 16-inch diameter optics. According to our optician, we need an aluminum disc the same size as the mirror with a reverse threaded hole in the center of the aluminum disc. This disc will be screwed onto a coupling which is attached to the shaft of the turntable motor.

We are currently working on sourcing the parts, machining, and doing a trial run with a 6-inch mirror. Then I get some blanks, get the curve I need generated to save me hours upon hours with 80 grit hogging out the glass before he can settle down and let the combination of grit, water, moving glass and time work their magic on the surface, every minute bringing me closer to optical eh-its-good-enough".

We have enough members in the club building telescopes that the effort of making these mirror grinding and polishing machines work is well worth it. With any luck, you'll see me at Stellafane next year.

There are many out there, who are intimidated by trivial things, such as sending a text, or even scrolling or switching between apps (what is even an app?).

So this course is ready made just for our parents. Or just for the ones who have no patience or capacity to teach these things step by step to their loved ones.

https://matcha.video is an in-browser transcription-based video editor. Remove silence and keep only the takes that you want with just a couple clicks. Export your edits to an XML format that you can bring into FCP or Davinci Resolve to finish. Free to use, data stays on your machine.

Note: this is a WIP, so if you have any experience working with .fcpxml, I'd love to hear from you!

aphit2• 2 years ago

Very cool!

I love this. In a quick test, I noticed the transcription missed on quite a few of my "filler" words that I might want to edit out, although it did get some of them.

It took me a little while to figure out how to "edit out" words.

EDIT: Turns out should I have read the instructions before uploading my video it would have been straight forward :D

hammeiam3• 2 years ago

I appreciate you testing it! The whisper model that I'm using indeed doesn't seem to pick up filler words, I'll try to add those ASAP. I'd also like to add background noise removal as a preprocessing step in case the input audio isn't the cleanest.

Were you able to import the result into your editor?

I'm a Master's student in Artificial Intelligence at UofT. Right now, I'm adding the "ML (Machine Learning) Streaming" feature to PyMilo. PyMilo is an open-source Python package that provides a transparent, safe, and end-to-end way for users to export pre-trained machine-learning models.

Transparency and non-executable export format is a serious thing, take a look at https://embracethered.com/blog/posts/2022/machine-learning-a....

After version 0.9 release, PyMilo became feature-completed with full support of scikit-learn models, now it's time to move on to PyTorch and then Tensorflow. But we decided to add the "ML Streaming" feature before getting into PyTorch, in order to provide an easy way to smoothly stream your ML model. By using the "ML Streaming" feature you can easily deploy your model into the remote server, connect to it from the client side, and choose the working mode, either delegation or local mode, through delegation mode your requests will be relayed to the remote server and you can easily work with your remote model from any devices without any further dependencies, and finally, you can download model for local use.

We will release the 1.0 (tenth) version of PyMilo around Sep 16th, this release will be the first release to have the "ML Streaming" feature with support of REST API, and we will next add other protocols such as Websocket.

Here is PyMilo: https://github.com/openscilab/pymilo Thank you for your time
