What are you working on? Any new ideas that you're thinking about?

Currently working on HN Alerts — a simple free site I made to alert me (via email) to trending stories on Hacker News.

It sends me an email once a story hits a certain number of upvotes per minute, so it's useful for keeping track of breaking news.

A reactive notebook with managed side effects for building backend/AI-engineering pipelines.

Reactivity can update the state of the notebook automatically, so you don't have to keep track of which cells to execute again. Side effects are managed to make it easier to reason about while maintaining reactivity and ability to interact with the outside world.

I've recently added autobatching to my SFML fork (https://github.com/vittorioromeo/VRSFML/tree/bubble_idle). Drawing multiple objects that use the same RenderStates will now be automatically coalesced into a single draw call, for example:

for (int i = 0; i < 10000; ++i) renderWindow.draw(sf::Sprite{/* ... */});

Upstream SFML: - 10000 draw calls (!) - My fork: 1 draw call

This (opinionated) fork of SFML also supports many other changes:

- Modern OpenGL and first-class support for Emscripten - Batching system to render 500k+ objects in one draw call - New audio API supporting multiple simultaneous devices - Enhanced API safety at compile-time - Flexible design approach over strict OOP principles - Built-in SFML::ImGui module - Lightning fast compilation time - Minimal run-time debug mode overhead - Uses SDL3 instead of bespoke platform-dependent code

It is temporarily named VRSFML (https://github.com/vittorioromeo/VRSFML) until I officially release it.

You can read about the library and its design principles in this article: https://www.vittorioromeo.com/index/blog/vrsfml.html

You can read about the batching system in this article: https://www.vittorioromeo.com/index/blog/vrsfml2.html

You can find the source code here: https://github.com/vittorioromeo/VRSFML

You can try out the interactive demos online in your browser here: https://vittorioromeo.github.io/VRSFML_HTML5_Examples/

The target audience is mostly developers familiar with SFML who are looking for a library very similar in style but offering more power and flexibility. Upstream SFML remains more suitable for complete beginners.

I have used this fork to create and release my second commercial game, BubbleByte. It's open-source (https://github.com/vittorioromeo/VRSFML/tree/bubble_idle) and available now on Steam: https://store.steampowered.com/app/3499760/BubbleByte/

BubbleByte is a laid-back incremental game that mixes clicker, idle, automation, and a hint of tower defense, all inspired by my cat Byte’s fascination with soap bubbles.

A trailer is available here: https://www.youtube.com/watch?v=Db_zp66OHIU

The first ever SQL debugger – runs & visualizes your query step-by-step, every clause, condition, expression, incl. GROUP BY, aggregates / windows, DISTINCT (ON), subqueries (even correlated ones!), CTEs, you name it.

You can search for full or partial rows and see the whole query lineage – which intermediate rows from which CTEs/subqueries contributed to the result you're searching for.

Entirely offline & no usage of AI. Free in-browser version (using PGLite WASM), paid desktop version.

Is this postgres only? What an interesting idea!

xarici_ishler11• 1 year ago

For now, yes, but I'll start working on adding support for all other DBs (especially OLAP) as soon as possible. The geberal approach is the same, I just have to handle all the edge cases of the SQL dialects

parrit2• 1 year ago

Was thinking today... not a debugger but even a SQL progess bar, so I know that my add column will take say 7 hours in advance.

IceDane• 1 year ago

This seems like it could be extremely useful.

xarici_ishler11• 1 year ago

Thanks! Would you mind sharing what would be your use cases?

At my job, all of our business logic (4 KLOC of network topology algorithms) is written in a niche query language, which we have been migrating to PostgreSQL. When an inconsistency/error is found, tracking it can take days, manually commenting out parts of query and looking at the results.

binary1322• 1 year ago

Nice one!

Ni3l552• 1 year ago

Cool! We're dealing with many complex CTEs and costly queries. Would be useful to have those visualized one by one.

xarici_ishler11• 1 year ago

What database are you using? I'd be happy to hear about your usecases and hopefully help you, shoot me an email (in profile)

benjaminsky22• 1 year ago

This is awesome! I’m work with a team of analysts and data engineers who own a pretty big snowflake data warehouse. We write a ton of dbt models and have a range of sql skill levels on the team. This would be the perfect way to allow more junior devs to build their skills quickly and support more complex models.

I would recommend you target data warehouses like snowflake and bigquery where the query complexity and thus value prop for a tool like this is potentially much higher.

xarici_ishler11• 1 year ago

Thank you, nice to get some idea validation from folks in the industry. For sure data warehouses are the top priority on my TODO list, I picked PG first because that's what I'm familiar with.

I can ping you via email when the debugger is ready, if you're interested. My email is in my profile

jeffhuys• 1 year ago

This would be incredible to understand why some queries execute slow; most of the time it's one of the steps in between that takes 99% of the execution time at our company. Do you record the time each step takes?

xarici_ishler11• 1 year ago

You're onto the original idea I started out with! Unfortunately it's very difficult to correlate input SQL to an output query plan – but possible. It's definitely in future plans

thebytefairy• 1 year ago

Can you not use EXPLAIN ANALYZE to identify steps that had the highest compute time? I think most databases have some form of this.

Suppafly6• 1 year ago

MSSQL has the execution plan thing that will tell you which steps are involved and how long they take.

thenaturalist• 1 year ago

Possibly look at https://duckdb.org/community_extensions/extensions/parser_to...

Even if not for DuckDB, you can use this to validate/ parse queries possibly.

xarici_ishler11• 1 year ago

Thanks for the suggestion! I am using https://github.com/tobymao/sqlglot, which magically supports most SQL dialects. And yes, support for DuckDB is also in future plans

I'm working on a workflow automation tool that lets devs write workflows in simple yaml files, and then deploy them to the cloud _or_ on premise. Each workflow is a set of actions and a trigger that can transform data, make api calls, run AI models, or really anything (via docker!). Each step relies on the output of the last step, and the workflow framework is engineering to be declarative, testable, and versioned. Similar to GitHub actions, but for *anything*. Think webhook to slack, email to support ticket, nightly aws backup & restore, mirror a file each night, etc.

I’m working on extending Postgres to run on top of FoundationDB. The goal would be turning Postgres into a distributed, horizontally scalable database with automatic sharding and replication.

Hoping to share a first version of it soon. It’s been absolutely fascinating digging into Postgres internals!

parrit2• 1 year ago

Is this something like what TiDb does with MySQL compatibility? Sounds fascinating!

fabianlindfors2• 1 year ago

Yes, pretty similar although I don't think TiDB is actually built on top of MySQL, instead it just reimplements the protocol for compatibility. My project is actually an extension of Postgres, which hopefully means much better Postgres compatibility in the long run!

I am working on the https://moviemovie.club/about, it's a tiny website about film review.

It works like a run club, where you have to make a review first to see other people's reviews.

I am currently implementing watchlists, comments and a mural to make it feel a bit less lonely. Right now I like the UI but it feels to lonely.

dewey4• 1 year ago

This seems like it would only work if “reviews” would be something rare to come by. Like some forums where you have to contribute to be able to download attachments, or see higher level subforums.

But reviews are everywhere, good ones too so it will be a hard chicken egg problem to solve.

What I'd love to be working on: Try to initiate a high voltage arc through the air to a target device, and modulate it to send "Data over Lightning", like Alyx does in Half-Life 2. It won't work the way it does in the game, but I'd it's an idea I've had for a long time and I'd love to prototype it some day.

rchowe2• 1 year ago

I have two:

The first is a preventive maintenance and calibration tracker (https://pmcal.net) that was born out of my day job as an engineer in small business manufacturing.

The second is an AI engine for pulling structured data out of incoming email (either via IMAP on your email server or via SES). If you think of the engine that powers TripIt, they had to write about 10,000 different ingestors for each airline and hotel and travel booking site. With a structured output AI, the need to write specific ingestors goes away.

andris9• 1 year ago

You can also get structured data out of mailboxes with my project EmailEngine. You can use an API request to fetch message contents, or you can configure EmailEngine to send a webhook for every new email in a structured JSON, for example, like this: https://emailengine.app/webhooks#messageNew

rchowe2• 1 year ago

I don't think I was specific enough on what kind of structured data. The idea is that it extracts information from the text/HTML content of emails (e.g. a flight itinerary from an airline booking email or an ingredient list from a recipe) using AI.

Since you already have a method for reaching into folks Microsoft 365 inboxes and such, you could probably train an LLM to extract arbitrary data based on a user's prompt quite quickly though.

MortyWaves• 1 year ago

I'm making some minor changes to my personal site/blog to improve contrast, have a more uniform usage of colours throughout, and also replacing "categories" with tags so that I can have related content easily linked and searchable.

I may also finally finish implementing WebMentions support too as a kind of comment section.

I may also work some more on my long-term relaxation/creative maze generation and solver project.

At work, I keep putting off yet more refactorings that are required because of poor/missing requirements and non-technical leadership of the project.

It wouldn't be so bad, but part of this "new" project involves communicating with some awful SharePoint """database""", as well as a poorly designed real database (it has multiple values in one column, not even with any standard, just sometimes there's extra numbers I need to parse, sometimes not - just lots of this type of crap repeated everywhere), and the worst development/deployment experience I've ever had to deal with in ~10 years.

To write code involves Remote desktop to what was a single core VM (and much protesting gained me... one extra core) to Windows Server 2016 meaning most modern/nice developer tooling isn't supported, and deployments are all done by copy pasting files over yet more nested remote desktop sessions.

Sadly there's no real way of automating any of this, every suggestion is always a "default no", again most of the tools I'd need for this won't run on Windows Server 2016, and even if I worked around it the stakes are way too high for "It's easier to ask forgiveness than it is to get permission".

The turn around time for even a small change is huge because of this mental burden, it's a complete slog to get anything done.

So I guess what I'm saying is I've been casually looking around at jobs this month.

This is why I always stress the importance of being able to work on my own projects, because otherwise, I'd have burnt out.

I'm working on a desktop-based, performance- and privacy-first note-taking app that lets you quickly capture notes from any selected text using hotkeys.

zolotorevich• 1 year ago

I'm curious: what are your must-haves in a note-taking application?

Unlimited undos. Even if I deleted text a year ago, app must bring it back. Ideally something like git, with branches and auto-commits.

entrep3• 1 year ago

Great, thanks. This is already in my minimum requirements.

maxrimue• 1 year ago

I thought about doing something similar some time ago, because I never quite found the perfect note taking app for myself. There's a million ways how to do notes, and it feels like there's just as many different notes apps.

Eventually, I've settled with Obsidian because of its simplicity and extensibility. You can leave it with basic features and truly own your notes in a simple format (you can also put them into any cloud, as long as that cloud reaches your filesystem). It doesn't do everything just like I'd want to, but I've thought about just building another notes app that reads and writes to the same path your Obsidian notes are in, instead of trying to cover every possible editing feature like most big notes apps. Then I'd use different apps for different needs, with one place to store data.

Since you're focusing on privacy, have you considered using Obsidian? Is there anything particular you want to do differently?

entrep3• 1 year ago

Basically I want to build it with focus on speed and work efficiency from start. To not bias myself too much, I will refrain from doing too much market research. First of all I'm building this for myself, and I'm guessing it might translate into at least a tiny market share.

I'm working on an escape room! Initially I was working on a software/hardware bundle that I was planning to market to other escape rooms but I think that is the wrong approach. So I am going to build a bunch of modular stuff in my garage and eventually start my own, its been an awesome project so far! I want a more dynamic and action oriented experience so it might not really be an escape room anymore but I don't know what to call it yet.

Escape rooms are honestly... almost always a let down but the concept has a lot of potential and there are some really neat ones that standout like this local one where you pilot an airship https://www.portlandescaperooms.com/steampunk-airship

Once I build the best escape room on the planet, I can consider selling the tools.

davepeck• 1 year ago

Have you ever visited a Boda Borg? They’re not quite escape rooms; generally, the experiences are fast-paced. Some are puzzles; some physical challenges; some, an interesting mix. Lots of computer automation to make it all work.

graypegg2• 1 year ago

Some sort of escape room backbone software that links together all of the hardware according to a script is such a neat idea. It would be so cool to have something like Twine [0] to build out the story graphically, where input/output is via cues to staff/hardware rather than just text on screen. An old boss of mine used to run home-haunts for halloween. (a walk-through haunted house experience scaffolded-up in his yard) I helped him a few times, and I was always amazed by how big of a community there was. There were at least 5-6 people doing a haunt next week and would come help out at his, then he would help at their haunt the next week. My boss was even making a magazine for the community for a while. Something for those folks doing quick popup theatrical events/escape rooms that could handle some "duct tape engineering" would totally have an interested market, and if it was open source you'd get great patches.

BUT I also get what you mean, have find out what works first. Do you have a blog for your escape room progress? That sounds like such a cool thing to follow you making!

A girl I went to HS went started an escape room business in my town, the first one they bought off of another company and customized it. Escape rooms need to refresh their content every so often, so the complete room or sometimes just the props end for sale. I was always curious about the tech side, if there were compatible 'systems' or if they are just one off things.

I'm building an open source game backend for Unity and Godot: https://trytalo.com. GitHub: https://github.com/talodev.

Talo makes it easy to add systems that traditionally need extra non-gameplay build time like authentication, player analytics and game stats.

Right now you can drop Talo into your game or use the API directly. Importantly, I’ve made Talo easy to self-host and you can point the Unity package/Godot plugin to your own Talo instance.

to-too-two4• 1 year ago

Is this a competitor to Heroiclabs (Nakama, Hiro, Satori)? Just trying to understand more where Talo fits. Seems like it's Hiro + Satori wrapped in one, but minus Nakama which would be the game server.

tudorrr2• 1 year ago

Yeah it’s in a similar space to Heroiclabs. Looking at Talo as Hiro + Satori makes sense.

A few big differences though: I don’t think those products are open source and Talo has a different philosophy when it comes to features.

I’m designing Talo to be a great base for features by providing all the necessary tools and infrastructure that developers can build from.

As an example, I see Hiro has a dedicated inventory system. In Talo, you can store and retrieve any data on players so you can keep all the logic around item configurations in your game code (where it belongs imo) and let Talo handle the saving/loading part in a generic way that makes sense for your game.

misterflibble3• 1 year ago

Can I ask what prerequisite mathematics you would need to know before reading those? I'm really interested in that topic and better understanding functional programming.

hyperbrainer• 1 year ago

If you wish to approach Category Theory from the viewpoint of a programmer, not a mathematician, I suggest Bartosz Milewski's book Category Theory for Programmers. For this, all you need is some previous programming experience. He uses C++ and Haskell iirc but as long as you can read snippets of code, you'll be fine.

I am suggesting this since you said you want to better understand functional programming. Category Theory, as mathematicians look at it, is an extremely abstract field. If you want to do pure math related stuff in Category Theory, and only then, I would say important prereqs are Abstract Algebra and Topology. I believe the motivation for Category theory lies in Algebraic Geometry and Algebraic Topology, but you definitely don't need to be an expert on these to learn it.

1. Eli5 equations(2) uses an LLM to convert a given picture of an equation to latex and, if given additional context, breaks down the equation parts to explain it. Gemini for the model.

2. reflecta - a journal prompting app with deepseek to help reword and target the prompts towards you better.

I'm still mulling how to go about porting my tiling window manager for Windows[1] to another platform, or even if I'll do it at all. There is some demand, but I don't know if there is _enough_ demand

Regardless of if I target macOS or Linux first, this would be a pretty full time endeavour on my part. I could wait until the commercial use licenses of the Windows version sustain me enough to be able to work on this full time, or try to raise a Kickstarter for $X00,000 to be able to quit my 9-5 and work on porting full time for a year or so

I have been working on http://phrasing.app - a language learning & acquisition tool for polyglots. I’ve been using it to study ~12 languages (5 on maintaince, 2 seriously studying, 5 casually “studying”) and it’s starting to feel really good. If anyone is learning/maintaining several languages, please reach out! I’m looking for beta testers in as many languages as possible (it supports 120+).

In what I believe is still the spirit of the question though, I discovered Maltese these week and have added it to my casual study. It’s a Semitic language (closely related to Arabic), written in the latin script, with about 40-50% of its vocabulary being Italian/Sicilian based. It’s become my new obsession

Would be great to be able to login via Google or Facebook. Creating an account is cumbersome on mobile.

muzani2• 1 year ago

Yes, please. I've been looking for something like this. Lately I've been just casually going into another language with ChatGPT and asking it to correct me. I do I like some of the old languages, things like Aramaic, which just have a different feel.

I signed up, but now it's asking me for a "reference language" (which is a little ironic because it tells me this in English lol). I guess I'll play with this later.

barrell18• 1 year ago

Start by creating some expressions ("create" in the nav bar) and you should be able to play around with it. If you want to learn more, please get in touch. As mentioned elsewhere, I'll be adding a video tutorial soon (probably not this week, but sometime next week if all goes well).

Would love to get feedback on the old languages! It's been really good for the minority languages I'm learning

Since you're in Amsterdam, I'm curious how well you think it performs for learning Dutch? I'm a native English speaker with a B2~ in Dutch and just looking to progress more. I've not used spaced repetition up to this point in my learning journey (almost 3 years).

barrell18• 1 year ago

It does really well, 95% of the time. The application was built to jump in at any levels - find a movie you want to watch, align the subtitles, see the most important words, create expressions with words you don't know, and the SRS should focus on the words most important to you.

For my Dutch (which was probably once a high B2, now probably a low B1) I only use the audio review when walking my dog or cooking. It plays the audio of the cards in a playlist, so I practice hearing and repeating them.

It's not so self serve at the moment, but if you get in touch I can get you up and running.

_puk• 1 year ago

Sounds good.

What languages do you support?

Learning Latvian through Anki flashcards, but it's not well supported by the main platforms, and there's not a huge amount of content out there for learning.

This alongside a couple of the usual suspects.

As a side note, on a Pixel 4a 5G (old phone , but functionally not ready for e-waste) the homepage bleeds all over. Some components into each other, others off screen. Might want to check that.

barrell18• 1 year ago

Oh no, the website is brand new, it should be working everywhere. I'll have to dig up an older android, I should have one somewhere.

Languages below, if you know their alpha 3 code. Currently having some issues with Thai and Zulu though, so they're temporarily disabled until I have time to fix them.

I have not ~tested~ verified it for Latvian, I would be curious to hear your thoughts. It has been working pretty well for Maltese, Albanian and Macedonian though, which should be lower resource than Latvian!

As mentioned elsewhere, the first time user experience is abysmal. If you reach out though we can hop on a call and get you set up - or in a few weeks I'll have a video done and up. In the meantime, you should be able to create an expression (in the nav bar for desktop and mobile) fairly intuitively.

i signed up and tried to use it. The UI is very confusing. i couldn't find the place to setup what language i want to learn and what language i know (for translation). It is best if you can have a video or images documenting how to use it.

barrell18• 1 year ago

Agreed. I’m getting close to a video to put on the landing page, probably some time next week.

The first time user experience is really bad, but the app itself makes a lot of sense once you see it in action. Feel free to get in touch with me (there are several methods listed when you log in) and I can give you a personal introduction!

If not then check back in a few weeks for a cool video :)

Mumps2• 1 year ago

I was quite eager to check this out. As some polite feedback, a few things turned me off quite strongly:

1. I want to get confirmation that the language I want is covered (Hungarian). "120+" doesn't confirm it for me, as Hungarian seems fairly rare for language apps. Can we not just have a "search your language" field?

2. I need to see what the app actually looks like, how it proposes it'll teach me.

I'm one of the eager-to-pay people, because Duolingo is frankly dogshit (ok. Mostly polite) at teaching languages (doubly so ones that it doesn't care about like Hungarian). But I'm so suspicious of language apps, due to being burnt a dozen times.

barrell18• 1 year ago

Thanks for the feedback! I agree with you completely.

1. I just started the marketing website a few weeks ago, and if you can believe it, I didn't readily have that information. One of my tasks last week was to compile a list of languages that could work, write some tests for all of the languages, and get a list of supported languages. I have that list now, I just need to put it on the marketing page.

2. As mentioned in other comments, I'm working on a video. I'm preferring to fix glaring issues before making the video, although at this point I'm verrrrrrry close. I have started scripting it, but it takes a lot of time to make a good video (1-2 full days if I don't want to edit it).

Your feedback is completely valid, and they're both reasons why I'm not really marketing the product yet. This thread seemed like a good middle ground though as having some people using all the languages would be really helpful. Also, I've genuinely been loving using it and want to share.

It's just me working on it, so these things are coming, but everything takes a while! Hopefully these didn't sour you on the project permanently :)

EDIT: And yes, it supports Hungarian :)

helenite• 1 year ago

The UI was a little unresponsive on mobile, and when I opened the "Media" page on desktop I got multiple block rendering errors. Opening the console reveals a syntax error (missing ] after element list) and some type errors.

Also, it looks like you have to get the subscription to use it in any way? It's hard to gauge whether it is for me or not if I have no way to trial it. I found the UI a bit confusing too, I was not sure what I was supposed to do after logging in. As another commentator mentioned, it's asking me to set a reference language but I see no way of configuring it.

barrell18• 1 year ago

Block rendering errors on the media page is new to me. I will look into it.

The reference language error should not be shown (I mean it’s not incorrect, but there is a “no expressions error” that should take precedence).

A video is coming :) I didn’t expect so much interest from a comment in this thread. If you get in touch, I can walk you through it personally, otherwise check back in a couple weeks and there will be a video overview.

bogdansolga• 1 year ago

I have just created an account and tried to use the app; either I am dumb (at this hour), or the app has a very not intuitive UI :-)

I (think I) managed to create an expression, but: 1. it takes forever, I don't know what it's doing and it's still not done 2. I have no idea how to use it, onward 3. does not seem that I will be actually able to use it, as the app requires to be subscribed to use it...

Looking forward for a how to use manual / page + a real trial period. If the app requires a subscription with this UX experience, I will be gone :-)

barrell18• 1 year ago

I am the first to admit that the UI does not make sense to people who have not seen it in use. I have done some user onboarding sessions where you just “let them ask questions and click” and it goes terribly if it’s any consolation, I have never gotten that feedback after showing people how to use it (quite the opposite actually!)

Wrt to the expression, all expressions created today succeeded, so if you’re still seeing a progress bar let me know as that’s a bug. It’s possible something failed with the live updates, or it does take several minutes to create an expression (depending on servers, it can take up to 10 minutes at times, although the typical timing is 2-4 minutes depending on the expression)

If you click on any of the review methodologies, it will start reviewing any of your successful expression. From there, the experience should be a lot more explorer-friendly :)

What it’s doing is: analyzing the sentence, splitting it into phrases, aligning it across all languages, tagging all of the gender/case/tense/etc, researching pronunciation, generating audio, aligning the audio, prioritizing the words (across several axes), and generation explanations/dictionary for each individual word

franklin_p_dyer2• 1 year ago

As someone who is both an avid language learner and a software developer - what’s the value added in this platform, for someone who is already pretty comfortable as a programmer and autodidact?

It would take a lot to convince me to pay that much for a product like this. True, it can be inconvenient trolling around for content in your target language, but as a software dev I am pretty experienced with finding obscure things on the internet by finessing search queries. And there are plenty of other apps out there that do spaced repetition for you, and open source tools and data sets that can be used to help you scrape/process vocab (again, if you don’t mind spending some time debugging, which I personally do not). Besides that, I really don’t find it that inconvenient to manually write down words/phrases from books or movies and copy them into my SR deck. On the contrary, I think this overhead actually helps the phrases stick better!

So how would you sell your site to someone in my situation? What would I get out of it?

barrell18• 1 year ago

I would have to know more about your circumstances before I could make genuine recommendations. But as an autodidactal programmer, I can serve as somewhat of an authority on this manner ;) The value I get out of the platform is:

1. I can study all my languages on the same platform. For my, having studied 30+ languages (note: not claiming to speak them), I just want to “do my languages”. I can study dialectal Arabic, minority languages, archaic languages, and the major languages, all in a nice consistent and (if I can say so myself) beautiful UI.

2. Everything is heavily annotated with all the information you could ever need. This means that I add flashcards, and when I’m learning them, I have the gender, cases, tenses, agglutination, phonetics, translations, audio, conjugation/declention tables, character breakdowns, mutations, idioms, multilword expressions, roots, etymology, etc etc (the list really does go on) at my fingertips. This means I just go through my flashcards, and when I have a question, I get an answer. If I have more questions, I have a context aware chat integrated. For me, this is the autodidactal dream come true.

3. Personally, I really love SRS. I also really hate SRS. If I have to study the words “dog”, “walk”, & “morning” - and I have a sentence “I walk my dog in the morning”, I just want to study that one one sentence and be done with it. Also, I really want to just be able to play audio sentences and listen to them while cooking/cleaning/walking my dog. Or do a free recall sessions, write down everything I remember from yesterday, and skip those reviews today (it’s more effective than SRS anyways).

Lastly, WRT to creating your own flashcards: You can still create flashcards manually on Phrasing - I agree the act of creating flashcards is beneficial, I’m not trying to take that away from anyone - but I’m not sure I buy it’s the highest leverage way for one to spend their time. At least for me, it definitely is not. I would rather skip that (admittedly beneficial) step, and move onto the next step. YMMV

It’s really hard to narrow the list down to three, I have a hundred things I want to say, but I’ll leave it here. Due to popular demand, I recorded a few live demos today so you can see it in action:

https://x.com/barrelltech/status/1917093849219895715?s=61

Higher quality demos will come in time!

Let me know your thoughts, I’m happy to dive deeper into any of this (I mean I could talk about Phrasing for literally days on end)

KomoD• 1 year ago

It sounded interesting so I wanted to try it but I couldn't figure out how to actually use it.

It says "We need to know which languages you already know. At least one language needs to be selected as a reference (some symbol) language."

I couldn't figure out how to add that, I also couldn't see that symbol anywhere...

Checked settings, profile, home ("open search" and "create expression" do nothing), create, globe icon thingy... eventually gave up.

jmkr2• 1 year ago

A midi sequencer, which does or is supposed to do what you expect.

In the process of adding stuff like euclydian sequences, and trying to figure out how to generate melodies. Been considering using something like a simple markov probability from a bunch of jazz standards, but also starting to read more music theory behind it.

It's a programming project but it's directly related to me trying to figure out music. So not a random sequence of notes in scale or not. The idea is more to generate backing tracks or song starters.

ludston• 1 year ago

That's a cool project, but learning music via music theory is a bit like trying to learn English via grammar theory. It's backwards, and out of the hundreds of musicians I've met, I've never met one that walked that path.

Strong recommendation: Hire a teacher. Even with experience playing four instruments, and when I decided to learn another, I still hired a teacher.

jmkr2• 1 year ago

One of my goals for this years was to get a jazz teacher, specifically for guitar.

A layoff killed that goal for the foreseeable future.

Theory has helped me practice like I think you're supposed to. More structured, more analysis. It also tickles the same part of the brain the certain comp sci topics do.

I think it came from wanting to learn how to improv, and then wanting to make my own songs. So I make a few tracks a week, of different genres, depending on what I'm interested in at the time. I've seen improvement, and I take notes about what I learned/what works.

reincoder3• 1 year ago

I appreciate you enjoying the game! I work for IPinfo but initially made it as a sort of meme for our users.

I'm generating random IP addresses on the frontend, then making an call to our free API to validate the "realness" of the IP addresses — mainly to remove bogon IP addresses, non-routable IPs, and IPs from large ASNs (national ISPs, the DoD, car companies, etc.).

Our free API supports 1,000 requests per day from unique IP addresses, so there shouldn't be any issues for low usage. However, if we get more power users who enjoy the game, I’ll switch to our Lite API service (which is also free, https://ipinfo.io/lite) to validate IP addresses, as it supports unlimited requests.

Let me know if you have any feedback for me :) I made it mostly by "vibe coding", I will write a post about the whole process of it.

Honestly a little bit hesitant to say anything yet. There are a few more features to add, and a whole lot more work to be done to showcase just how cool it is. But the short version is, I'm working on a sort of meta-pico8, a game maker for WebGL2 2d pixel art games (e.g. 320x180 games like Animal Well) that runs in the browser, but one that's firstly collaborative, so that we can all build it together. And some of the coolest features are the based around that. For example, I got arbitrary imports of user code working in the browser, so all you have to do is create an account, add a JS file, and other people can import it as if it were a built-in module, and it just works. Plus the SDK I ended up making is simple, and the API is clean, and there's a few innovations in the GUI layer that I'm excited to share. I wish I could explain just how cool this is.

whitehexagon• 1 year ago

Interesting, I have been working on a similar project, albeit 320x240.

I also got some code-share and collaboration features working, but got a bit stuck on fonts. But I can appreciate your feeling of 'how cool this is'

I ground to a halt once I realised I had no barrier to entry, ie it could be cloned very easily. Always an issue with Web Development I guess. Plus I hate what modern browsers have become in recent years and not sure I want to target such a fast moving platform. I got burned once already with WebStart 'warning this app might do something scary' and certificate fiasco.

I thought about some native binaries, but I know I am kidding myself. I had an ios app that was pixel cloned within 6 months. But somehow a web app feels like publishing straight into public domain.

90s_dev2• 1 year ago

It's not just the web, native apps have always had free open source clones that technically render them useless, often just as good quality, yet they didn't go out of business. There are other considerations people make when deciding to use an app, including network effect, a strong community, sheer level of quality and passion from the developers, etc.

For fonts, I just went with a simple raster bitmap font and pixel grid storage format. Creating these limitations makes it easier for me and for developers and artists. I choose 320x180 because it fits the 16:9 perfectly, which would make full screen ideal on most monitors.

pacmansyyu• 1 year ago

I'm working on Damon[1], a Nomad Events stream operator that automates cluster operations and eliminates repetitive DevOps tasks. It's a lightweight Go binary that monitors the Nomad events stream and triggers actions based on configurable providers.

A few examples of what it can currently do:

- Automated data backup: Listens for Nomad job events and spawns auxiliary jobs to back up data from services like PostgreSQL or Redis to your storage backend based on job meta tags. The provider for this is not limited to backups, as it allows users to define their custom job and ACL templates, and expected tags. So it can potentially run anything based on the job registration and de-registration events.

- Cross-namespace service discovery: Provides a lightweight DNS server that acts as a single source of truth for services across all namespaces, solving Nomad's limitation of namespace-bound services. Works as a drop-in resolver for HAProxy, Nginx, etc.

- Event-driven task execution: Allows defining custom actions triggered by specific Nomad events; perfect for file transfers, notifications, or kicking off dependent processes without manual intervention. This provider takes in a user-defined shell script and executes it as a nomad job based on any nomad event trigger the user defines in the configuration.

Damon uses a provider-based architecture, making it extensible for different use cases. You can define your own providers with custom tags, job templates, and event triggers. There's also go-plugin support (though not recommended for production) for runtime extension.

I built this to eliminate the mundane operational tasks our team kept putting off. It's already saving us significant time and reducing gruntwork in our clusters.

Check out the repository[1] if you're interested in automating your Nomad operations. I'd love to hear your thoughts or answer any questions about implementation or potential use cases!

I really like this idea of silent monitoring. Monitoring and talking about bad things seen weeks/months later. Because while I can block everything I want at home… there are other kids with free Internet access where everything is available and then I have no idea what’s happening.

muzani2• 1 year ago

I've been using something like Google Family Link, which works fine, except that it ties in to Google Family, along with YouTube, Play Store, Google One. I'd have to kick my sister out of the group to monitor another daughter and it means there's a limit on the number of children you have; such terrible design.

I do want to give them a little privacy and it gets to the appropriate level. Like restricting some apps at certain times, access to chrome but not xhamster. Locking it for certain periods of time and having them request more screen time past 4 hrs/day. Locking the phone whenever they've barricaded themselves in the room the whole morning.

I don't necessarily mind that they're watching YT or TikTok and such. I just want to kick them out of the doom scrolling cycle every now and then.

I respect every parent's decision regarding how they raise their children, but I invite you to reflect on whether growing up under this level of surveillance is something you would have wanted for yourselves.

I’m working on LookAway (https://lookaway.app) to help people stay healthier and more productive during prolonged screen time.

My main challenge has been making meeting detection more robust -- it currently uses both mic and camera activity, which led to a lot of false positives. In the next version I’m switching to mic only (the camera caused most of the noise) and I’ve added a way to identify which app is using the mic, so users can exclude non-meeting apps.

I’ve also added plenty of small tweaks throughout to make LookAway even less interruptive. I’m excited for the next release!

kavalg6• 1 year ago

I am working on the sunflower plant density estimation problem. The goal is to be able to estimate the germination rate as early as possible. Farmers benefit from such information, because:

- there are lots of expenses still to be made (fertilizer, pesticide, salaries), which may not be worth it if germination is under certain threshold

- if detected early, there is still time to plant another grain or to fill up the missing plants (requires precision seeders and seeding maps)

- is a very good proxy for yield estimation (farmers often trade futures even before they have harvested)

For the purpose I have created a dataset (a collaboration between my employer and Sofia University) and published it in order to enable scientific collaboration with other interested parties. Still working on the dataset annotations.

ragebol• 1 year ago

Interesting, I'm also involved in a project to do yield prediction, but with a ground-vehicle with camera's on top to drive between strawberry and blueberry plants.

Yield prediction is huge indeed, because overshooting your prediction means seller stuff for a lower price. Undershooting means paying for someone's product to make up for the difference. Probably there's quite a bit of matchmaking in between those under and overshooters and someone making a good buck out of that too.

kavalg6• 1 year ago

Undershooting means paying for someone's product to make up for the difference

Indeed. Making up the difference can easily eat most of the farmer's profits. I guess it is even more pronounced for berries when compared to grains, because they cannot be stored for so long.

Simon_O_Rourke• 1 year ago

Very cool, what type of parameters are within your control if detected early?

kavalg6• 1 year ago

I am not sure that I understand your question correctly, but given more precise sunflower density estimation, the farmer has three options:

1. Plow the field and seed again (same or different variety or grain). This is a very crude measure, but it is sometimes the right thing to do, because as I said most of the expenses have not been realized yet (fertilizer, pesticide, fuel, payroll, paying rent for the land). It is also a time critical decision, because the window of opportunity for plowing and reseeding is not very wide.

2. Accept the lower yield if it is within a reasonable margin (e.g. comparable to the expenses to plow and reseed).

3. Do partial reseeding over the existing plants (without plowing). This is an emerging strategy with the proliferation of smart seeders, but it requires a precise seeding map to be created beforehand (i.e. based on the density estimate). As an advantage, you spare the expenses for seeds and plowing, however there is some disadvantage as well, due to the different rate of development of the newly seeded plants. Farmers usually need plants to be ready for harvest at the same time, otherwise the quality of the grains suffers and hence the selling price is lower.

In addition to these points, having precise density information after germination helps with the identification of problems, such as seeder malfunction (e.g. nozzles getting clogged), seed quality and meteo data (e.g. too much rain, low temperatures etc).

firesteelrain6• 1 year ago

Feel like this basically enabling the use of ANOVA? (Compares yields across different treatments (e.g., irrigation methods, seed types).

kavalg6• 1 year ago

It is possible. However, getting accurate yield data requires a "smart" harvester that can produce yield maps. Many modern harvesters are equipped with GPS and various sensors, so it is possible. However, farmers are really slow to replace old equipment if it works fine. I guess there are some retrofit solutions for yield mapping, but I haven't investigated their affordability and penetration into the (EU) farming landscape yet. Additionally, there are other interesting parameters apart from the harvested quantity that can be captured (e.g. the quality of the grain itself, such as size, composition, humidity etc).

ellisv3• 1 year ago

Fisher invented ANOVA specifically for analyzing crop yields so it's a natural fit.

However for precision agriculture kavalg might want to consider other methods.

tringuyen_cse• 1 year ago

Hey, this is interesting. I used to work on a somewhat similar problem. Our problem was more general, but one usecase is to predict the number of interactions between flowers and pollinators, given some initial counts. As these initial counts are obtained manually (by going to the fields, taking pictures and count, like number of bees within a frame), those count numbers are likely to be lower the the actual numbers. We addressed this under-counted issue using low-rankness and Poisson mixture model. Take a look if you're interested: https://ieeexplore.ieee.org/document/10888717

I develop Chips of Fury, a poker app for playing privately with friends. Currently I am building support for lots of home game variations like pineapple (regular, crazy, lazy), different Holdem variations like Super, reverse, super reverse, blind man's bluff etc and many more. I am thinking about how to implement AI bots for a wide range of variations.

soylentgraham• 1 year ago

Ah, I've made the same! I made a very flexible turn-based framework - write the game logic on server in javascript, then state+options are given to clients, so platforms (swiftui, web, unity, webxr etc) "just" have to implement UI on top (Also means I have a default/debug view, which works for all games). The games can run offline (via javascriptcore on ios, natively on web etc) and supports bots for all games (they randomly choose options on their turn) which has a very simple opening to get some reinforcement learning in.

Then specifically I was making an app which let me customise rules for poker - extra streets, antes, throwaway cards, passing cards, multiple boards, multiple decks, etc to support as many variants as possible, and ideally, stumble across new ones.

As an aside, I posted to reddit for research of other home variants people play (Basically to stumble across more fun variants in our home games) there's a few good alternatives I've not heard of in here!

https://www.reddit.com/r/poker/comments/1i91mnz/what_are_you...

Give some variables to the prompt and creating infinite versions of same prompt by providing the value. Or having the versions of each prompt.

- our app and communication protocol is open-source, and we provide code for compatibility with the major bike controllers, meaning we're compatible with 90% of the e-bikes!

so in practice we're the perfect battery for e-bike enthusiast who want to change their battery to a repairable and fireproof one

and we also do B2B deals with some brands who want custom design etc

but basically if you are running Bafang / Shimano / Bosch controllers, it will work with our battery

Also doesn't use the Pocketbase client library at all, all calls are wrapped in their own API routes and everything is server side rendered.

You might ask why use Pocketbase at all, and I'm not sure anymore. I suppose the dashboard is great, built in auth is great (although I've had to write cookie middleware to make it SSR anyway). I wish there was a lightweight Pocketbase/Supabase style "backend in a box" setup that didn't push the whole client library directly communicating to DB paradigm.

I’m working on a simple app that logs Karting activity and data. My son has been karting for a year or so, and there is so much data to collect - times, pressures, sprocket set up, track location, weather and more (about 30 datapoints a session)

Collecting the data helps with recording engine performance, tyre ages, best lap times but is also really useful for recalling how well each setup performed for future reference.

I’m deliberately doing this all in a very low-tech way as my son will be creating a more polished version for a school project. We’re front-running that a bit to give him a good dataset and explore various ideas.

On that note, they do Python in school. For the backend it will be SqlLite and Flask. Any suggestions for the front end tech? This will mostly be forms- and grids-based so nothing sophisticated needed, but some simple client-side logic (e.g. validation, geolocation, simple stop watch) would be good. Ideally this would be python as well. We could use WebAssembly but am wondering if there is a suitable framework that does the is out-of-the-box.

While Git is great at asynchronous collaboration, its a bit clunky to try and work on the same commit with other devs or across devices. This is because Git tracks what changed, not how it changed.

It'd be cool if you were on the same branch as somebody else, or another device, and your working directories could be synced. It'd also be cool for the commit history to be a bit richer, so you could see who, what and when for a change at a keystroke level.

So I'm working on real-time sync for Git! I'd represent the working directory as a tree CRDT [1] and sync that through FUSE and p2p networking.

Not sure whether this is actually a good idea! This is a POC :)

i don’t quite understand, what makes it reverse typesetting?

my understanding is your typesetting books for responsive eink readers.

perihelions4• 1 year ago

You're inferring the structure of the document from the printed result. If typesetting takes a set of layout directives and outputs a page, this is taking a finished page and guessing what layout directives could create it. Then you can take that inferred structure and reflow the page in a new layout.

I've been working on onsite deployments for https://www.keystash.io, which is a Linux SSH Key and User management system. It's been going for a while now and I am finally implementing onsite deployments as so many customers actually want to run this themselves. When we started, we really thought customers wouldn't want the hassle of another piece of infrastructure to manage, guess we were wrong :-)

Onsite deployment is a lot more difficult to make slick and easy. We've been thinking about the best way for our customers to deploy while reducing the load on our support team. So far, we are thinking about RPM's, Debs and Docker and trying to make this as close to a '5 step process' as possible.

I would love to hear people's thoughts on other mechanisms that make it easier for SRM's / DevOps to manage key platform infrastructure software.

Performance is rock solid, and it’s almost ready to release, I just need to tweak a few things (like free trial with no CC).

wturner• 1 year ago

I've been using elixir to build an app that lets an administrator add new rss feeds, render the article titles and summaries to a single page, scroll through them and push the ones they like to a landing page as a collection to read later. Many of the sites I like don't have the conventional RSS "structure" so I have to modify my main parser and adapt it to the outliers. I'm curious, how do you adapt to feeds that don't fit the conventional RSS structure? I was thinking of just using an LLM to automate it as I keep using Claude AI to expedite the process.

hsx2• 1 year ago

Do you mean they technically have RSS, but they’re using slightly different fields? E.g. summary instead of description?

I’m using FastRSS[^0] with some lightweight pattern matching to convert them to an internal model. I get error notifications for mismatches, and just push a new pattern match to handle the outlier.

Longer term it could be interesting to get an LLM to write some Lua to parse JIT.

I’m building ninja.ai — it looks like a one-click App Store for MCP Servers, but the real goal is much bigger: creating a “Universal Fabric of Context” that lets AI tools tap into structured information across the web easily.

It started when I found it surprisingly hard for my partner to install and connect MCP Servers — even simple ones. I realised if we want AI agents to really interact with the web, it needs to be as easy as installing an app.

Right now, you can browse, install, and connect servers in one click. Over time, it’ll make AI integrations as easy as installing an app — no messy APIs, no custom scraping.

If you’re working with AI models, agents, or data-heavy tools, I’d love to hear what kinds of “context pipes” you’d want to see added.

So far it has some sort of activity calendar + expense tracker

There's still so much ideas to implement, like adding map, improve UX of creating activities, to-do list, etc

I've used it once or twice of a short trip, but in 6 months time, I'll have a 2-weeks trip, so that's my self-imposed "deadline" for this project

Anyway this project is a pure static web page and all the 'back-end' is handled by InstantDB ( https://www.instantdb.com/ ) after I saw their submission on HN >.< So far it has been quite a good experience overall except maybe the permissions model which can be a bit confusing to me

Been a freelance dev for years, now going on "sabbatical" (love that word) imminently. Just moved to reduced hours, still in the transition and unwinding phase.

Planning to do a lot of learning, self-improvement, and projects. Tech-related and not. Preparing for the next volume (not chapter) of life. Refactoring, if you like, among other things.

I'm excited.

rellfy2• 1 year ago

I've been working on https://asterai.io -- a platform for developing, running and managing AI agents.

It lets you create multiple agents, configure them via the web console (such as LLM parameters and system prompts) and manage their plugins and functionality.

The system is fully plugin-based, where each plugin is a WASM program that exposes functions/tools that the agent can call, and can also hook into the query lifecycle. Because plugins are WASM, they can be written in various languages such as Rust, Go, TypeScript etc. Plugins can also act as libraries, which is possible because of WebAssembly Components (a great piece of software!) -- so you can dynamically call functions from other plugins within your agent, and you get type support for your chosen language too (with codegen via WASM Components tooling).

More recently, I've been working on an SSH server for agents. The idea is that you can add public keys to your custom agent and then SSH into it to talk to it easily from terminal.

If this sounds interesting, feel free to join our Discord! The project is still new and feedback is highly appreciated. http://asterai.io/discord

meander_water• 1 year ago

This looks interesting, how do you plan to handle agents which operate apps with a UI - for example playwright, obsidian etc. Or is this out of scope?

rellfy2• 1 year ago

Thanks!

That's a good question. Currently, there is one way to do it. The client querying the agent receives JSON-encoded values that are returned from plugin function calls made by the agent. These values are received alongside the agent token response stream (via SSE). So plugins can essentially emit events that the client can forward to the UI application, such as to click a button etc. The limitation with this is that there is no built-in way to send a success/error status back, it's one way only. It works well for actions that are infallible such as simple UI actions.

The client here would also need a way to interact with the target program of course, e.g. from a JavaScript browser you can click buttons and manipulate the DOM, or from a VSCode Plugin you can interact with the editor etc.

It's definitely something that can be improved though! I've been thinking about some type of MCP interoperability that could maybe assist with this.

Last year, I repurposed an old laptop into a simple home server.

Linux skills? Just the basics: cd, ls, mkdir, touch. Nothing too fancy.

As things got more complex, I found myself constantly copy-pasting terminal commands from ChatGPT without really understanding them.

So I built a tiny, offline Linux tutor:

  - Runs locally with Phi-2 (2.7B model, textbook training)
  - Uses MiniLM embeddings to vectorize Linux textbooks and TLDR examples
  - Stores everything in a local ChromaDB vector store
  - When I run a command, it fetches relevant knowledge and feeds it into Phi-2 for a clear explanation.

No internet. No API fees. No cloud. Just a decade-old ThinkPad and some lightweight models.

Working on Uncloud [1] — open source tool for self-hosting containerised apps across multiple machines. You can combine cloud VMs and on-premises to create hybrid compute environments, e.g. for cost optimisation or data privacy.

While Kubernetes offers power at the cost of complexity, Uncloud focuses on simplicity for common deployment workflows.

Progress from this month:

  - Enhanced Docker Compose support: You can now deploy your entire stack from standard Docker Compose files. This includes volumes, environment variables, resource limits, scaling and logging configuration.
  - Volume management: Create and manage Docker volumes across your cluster with automatic scheduling based on volume location.
  - Context management: CLI command to quickly switch between multiple clusters, e.g. homelab and production one

I'm particularly excited about the volume management system as it provides the cluster semantics to the good old Docker volumes. It uses a constraint-based scheduler that ensures services sharing volumes are properly co-located.

If you're seeking something between "just Docker" and full Kubernetes for deploying applications on your own infrastructure, I'd love to get your feedback on Uncloud.

I've been working on https://textquery.app -- query raw data from your desktop.

I love exploring data, but it always felt clunky to juggle multiple tools, write code/commads, just to import and query a dataset. While there are multiple GUI tools for databases, none are focused on raw data.

TextQuery is the tool I built to solve that. You can import CSV, JSON, and XLSX files and start querying them instantly using SQL. Want to create a chart? Just hop over to the Visualize tab.

I'm also rolling out a major update this week — adding tabs, filters, a redesigned UI, and keyboard shortcuts.

Looking ahead, I’m planning to expand support for more formats (like Parquet and ORC) and data sources (like Postgres and BigQuery), so you can import data from anywhere, and query it right from your desktop. Something like a local data warehouse. With Apple Silicon, the capability of a desktop can make it very cost-efficient compared to something like BigQuery, Snowflake, or Athena.

Happy to hear any feedback!

I wrote a novel in French a couple of years ago that I want to translate to English. The way I do it is paragraph by paragraph: copy/paste a paragraph in OpenRouter (Sonnet or Gemini), get back the translation, and rewrite/adjust it.

It works well but copying/pasting back and forth gets old very fast, and it would be better if the process was done inside the word processor. For some reason (various reasons) I still use Office 2003, which doesn't have any AI feature. (It does have a "translate" function but it's awkward to use and not very good.)

So I wrote a macro to send selected text to OpenRouter and replace with the response (with a system prompt that says to only output the translation, otherwise most models start with "Here's the translated text:")

I had never written a macro in vba; I got started with Sonnet and adjusted many parts with the help of StackOverflow (which turns out to have more information about vba than Sonnet...)

And finally it worked; and it turns out to be an incredible boost to translation productivity!

I'm working on a Kaggle competition about predicting subsurface models - a map of the geologic layers beneath a given area - from seismic data.

I like competitions like this that are connected to physical problems and datasets (though sadly this one is largely simulated), I learn as much about the broader world as I do deep learning. I've always idly wondered how seismology worked, and now I have an excuse to dig into it.

It's also given me a greater appreciation for the "seismology" we perform in our day to day, like knocking on things to see if they're hollow, or (as I learned here a while back) the way battitores test the porosity of cheese by knocking on it with hammers.

If you are a small to mid-sized team, moving to Bazel is massively painful and basically requires up to one full-time position to provide your team with a good experience.

Grog on the other hand let's you keep your existing build setup while just parallelizing and caching it. It's not a full replacement, but it's more than enough for most mid-sized teams that want to have fast mono-repo builds.

I started experimenting and I think this builds out pretty neat estimations from jira tickets/other descriptions. When I was sitting in the CTO role, I spent a ton of time talking with people about how long/short various projects would be. When I was a developer, I hated the estimation piece because it felt like it was both keeping me from building and was almost never done with enough context to get really accurate results.

I was playing with the OpenAI API and I noticed that they can actually return a set of probability x next tokens and I thought that it might actually give you kind of cool ways to see the distribution of potential outcomes. (You can see an example here: https://universalestimator.com/estimates/c68db45b-7622-4bab-... that looks at a detailed ticket for implementing filtering on a dashboard.)

No, but it's on my roadmap! https://feedback.universalestimator.com/p/calibrationnorms-f...

Right now, it asks you some follow up questions and assumes you're a medium sized org, but I'd like to start to move that into configuration and do some sort of time/bayesian expiration of memory/information as part of the questions it asks.

I think a ton of the variance between teams is probably captured by some version of a few calibration questions, aka: - How large is the org? - What region is your org based in? - How long does it take to get the smallest possible change into production?

A pentagonal geospatial indexing system: https://a5geo.org/

If you’ve used H3 or S2 it should be familiar, the major difference (apart from the fact it uses pentagons) is that the cell areas are practically uniform, whereas alternative systems have a variance of around 2 between the largest and smallest cells, making them less useful for aggregation. The site has many visual demos, e.g. https://a5geo.org/examples/area

The code is open source: https://github.com/felixpalmer/a5

No, it is based on applying a lattice onto the faces of a dodecahedron (technically a pentakis dodecahedron). Take a look at https://a5geo.org/examples/teohedron-dodecahedron and other examples on the website.

H3 is based on a dodecahedron it is it the reason the cell areas range so much, the same is true of S2 - but this is based on a cube.

The cells being the same shape is useful in some use cases and irrelevant in others. For example, see the Airbnb demo: https://a5geo.org/examples/airbnb. The H3 tiles are very different sizes in the two cities, and make it appear that there is a much higher density of listings in Malta, even though that is not the case.

However the symmetry of H3’s hexagonal cells lends itself well to flow analysis, or routing - which is no surprise as it was developed at Uber.

As for the name, it follows the convention of S2 and H3, which come from group theory and refer (loosely) to the symmetry groups of the various systems

I am working on an app for rhythm training for dancing. The first step is beat detection in music - here is my code for generating videos with beat counting: https://github.com/zby/beat_counter (vibe coding warning). Beat detection seems to work OK, downbeats are a bit more tricky and I have found not good solutions for further structuring of music (for dancing they usually count to 8 - that is two 4 beat measures - or 6 - two 3 beat measures for Waltz for example, I am not sure about 2/2 measures and other). Seeing all the LLMs generating music I thought there should also be LLMs interpreting music - but so far I have found no such model the available algos seem to be from a previous decade.

My current plan is to test the counting with people with good rhythm sense and once I find a good algo for beat detection I'll proceed with writing the app.

https://mysukari.com - A Diabetes management platform

I got diagnosed with type 1 diabetes in Feb (technically LADA as it's late onset). I'm the first in my family with it so I had zero info on it. I tried getting some CGMs to use but most don't work in Kenya as they are geo-locked, and even apps for measuring carbs like CalorieKing are not available in my region. I was really frustrated with the tech ecosystem, and started working on My Sukari as a platform of free tools for diabetics.

I mostly get time to work on it on the weekends, so it's not yet ready for public use, but I've fully fleshed out one of the main features: Sugar Dashboard - A dashboard that visualises your Glucose data and helps you easier analyse it.

To help with demos, I've shared my Sugar Dashboard here: https://mysukari.com/tools/sugar-dashboard/peter

I'm really passionate about this and getting as much free, practical tools in the hands of patients (it honestly shouldn't be this hard to manage a disease)

westpfelia2• 1 year ago

Is this just for Type 1 or would type 2 work well also? Seems like it would?

_Chief5• 1 year ago

All types. The sugar dashboard allows import of data from different glucose apps, so its goal is to allow you visualize and analyze your data. I hope to integrate with cgms directly if I get some that allow it, and also source from Health connect. Sharing with specific people eg doctor is also a big ask that I'm working on. The other WIP tools will be fore general health, not just diabetes, like carb counting from a photo via AI

shiggaz• 1 year ago

That's so cool! Nice work!! Are you happy to share how you built and host it? How long has it taken you to get it to this point?

_Chief5• 1 year ago

Thanks! I started out with a Nextjs full stack on Vercel, with db on Turso but ended up with a React frontend (next on vercel) and Go backend (selfhosted on vps).

Decided to port the backend to Go + postgres (on a Hetzner VPS), and retain the frontend on Nextjs - A lighter weight client, moving most of the compute to the backend API. Few reasons for the port: I've had a lot more success/stability with Go backends, Turso pulled multi-tenant dbs which is what I mostly wanted them for, Nextjs is getting too hard for me.

Go backend is just the std lib (1.22+ server with the nice routing) - I mostly write all the lines in this

Frontend is textbook modern react: React19,next15,tailwind4 - AI mostly writes the code in the frontend (Cursor + Cline + sequentialthinking + context7 + my own custom "memory bank" process of breaking down tasks). AI is really, really good at this. I wrote this https://image-assets.etelej.com/ in literally 2 days 2 weekends ago with less than 10% of code being mine (mostly infra + hono APIs)

Are you familir with xdrip? (https://github.com/NightscoutFoundation/xDrip) It works directly with various cgm sensors (dexcom etc.)

_Chief5• 1 year ago

yes, came across xdrip+ when looking for an android app I could use for Libre 2. I don't think Dexcoms are sold in Kenya, and even the Libres around are UK ones so you need 1) a VPN to setup, 2) an iphone. Both things being a challenge for most - I had to buy a my first ever iphone for this. Anyway, found xdrip a bit of a challenge to setup and a bit too technical to suggest to others; needs sideload and manually disabling a lot of Android defaults.

I had a lot of success with Juggluco[1] which is available on the Play Store and provides easy to use APIs to interact with supported CGM readings. Juggluco has an inbuilt xdrip web server but I haven't tried it yet.

Will definitely look into xdrip+ further.

I used to work for Lark. They raised $140mm to solve this problem and the best they could do was a non-ai chatbot that whined at users for not eating enough vegetables. The Lark app has 100% user drop off in 60 days and yet is still the silicon darling in the diabetes space.

Your platform has more science & more solution than 100 engineers in 3 years could produce. Keep at it and know with confidence that there is great value in what you are building. I know it's not your primary goal, but this will be lucrative if you keep going. I wish you a lot of luck, this is very cool!

Silly lisp-inspired language, but it turned into something different as I started asking myself more and more questions, and now it's more of a model for computation that tries to think about computers as different from looms (aka harward architecture). One where self-modification is the norm, where there is no stack unless you make one, and where there's no difference between a program extending itself or the programmer doing it (unlike LISP macros, my language, and model, does not have a distinction, there's no macros).

I'm not doing this because I'm convinced it's a great idea, or because it's going to revolutionize computing, or because it will be a good language, model or beneficial in any particular way, I'm doing it because I think it's fun, neat and interesting to think about (and talk about).

(1) Business process modeling tool where processes are data and not graphs. I am doing it according to the USM method. USM is kind of "open source" service management method, although it works on different level than other frameworks and standards, and is compatible with all of them.

This makes it possible to create a kind of requirement "programming language" where the requirements can be evaluated. With this language it becomes possible to create cross-references from various compliance standards/frameworks, like ISO27K, to USM, and automatically evaluate the compliance.

(2) Dance event calendar in Finland, running in production for over a year. 1-2M page views/month. Django app, but I am now implementing a copy of the unauthenticated user views to S3 bucket and delivering it through Cloudflare.

(3) Django app to handle all the data related to custody trial. Emails, SMS, notes, official records, voice memos, etc. can be attached to a timeline, and tagge and searchable. It has command line interface for adding data, in addition to UI, so I can quickly add notes and attach files.

Two things.

I have revived my work on Go Micro (https://github.com/micro/go-micro) and rewritten the v5 cli/api from scratch (https://github.com/micro/micro). As a VC funded company there was a lot of confusion around the tools we were building and we veered off in a direction that alienated the community. With the company dead, funding gone, etc there's an opportunity to rebuild value around the Go Micro framework.

The second thing I'm working on is the Reminder (https://reminder.dev && https://github.com/asim/reminder). As a muslim I feel like it's my duty to spread the word of Islam and as an engineer I feel like an appropriate way to do that is build an app and API for the Quran, names of Allah and hadith. It's a slow patient building of something as opposed to expecting anything from it.

In terms of new ideas, maybe not new but less screen time, less phones, more nature.

I'm working on a new open source CAD program for 3d printing based on Signed Distance Functions.

Benefits of SDFs over the standard Boundary Representation (used in Freecad and similar) are that you can do "pattern" operations with domain repetition, which means making N copies of a feature is O(1), vs O(N^2), you can deform objects with domain deformation, which means if you have a closed-form representation of how you want to deform space you can basically directly apply that to your object, procedural surface texturing is easy, CSG operations are easy.

The big drawback is that it is hard to provide any workflow based around "selecting" faces, edges, or vertices, because you don't naturally have any representation for these things, they are emergent from the model's SDF.

I have some blog posts on my progress: https://incoherency.co.uk/blog/stories/sdf-thoughts.html and https://incoherency.co.uk/blog/stories/frep-cad-building-blo...

I am solving the "selecting faces" problem by having the SDF propagate surface ids as well as distances. So the result of the evaluation is not just the distance to the nearest point on the surface, but the id of the specific surface that is nearest.

My next big frontier is reliably providing fillets and chamfers between arbitrary surfaces. I have a handful of partial solutions but nothing complete yet.

The most promising idea is one that o3 came up with called "masked clones", the idea is roughly to make a clone of the 2 surfaces you want to blend, mask them by intersecting with an object that is like a "pipe" along the intersection of the 2 surfaces, apply the blend within the pipe, and then add this "blend pipe" as another child of the lowest common ancestor of the 2 blended surfaces.

And after that I need to work on more standard CAD stuff like constraint solving in the 2d sketch editor.

mungoman2• 1 year ago

This is super neat, cool that you have an online demo as well.

I wonder if there are any ideas on how to make this a OpenSCAD-style editor instead of interactive? I like the text-based style for simple regular shapes, but they tend to end up too simple and regular. Maybe tools like filleting edges SDF-style is a game changer?

jstanley2• 1 year ago

I actually don't really like the OpenSCAD-style interface. For me FreeCAD is the current state-of-the-art in CAD.

But if you are into code-style SDF interfaces, I have some links on https://incoherency.co.uk/notes/sdf.html

coderenegade• 1 year ago

This is cool, and something I've thought about a lot, as I'm pretty unhappy with the state of CAD on Linux. The world definitely needs another open source CAD kernel, and I was toying with making my own before I decided to pursue something else.

I think the problem of finding edges can be solved by stepping back and redefining primitives. One idea I had was defining them as a 2D sketch and a transformation function along a path. A sphere would be a 2D hemisphere that rotates as it moves along a circular trajectory, with the flat side staying in place, for example. A cube would be a square That moves along a vertical or horizontal path the distance of the sides. You get the idea.

The advantage of this type of representation is that edges can only ever be edges in the 2D shape, or the path traveled by vertices. The hard part is that when you do boolean operations using primitives, you probably want to go back and turn it into a primitive representation (2D shape, transformation along a path).

I'm working on a running app. Mainly for me but others have expressed interest.

It's a performance analytics platform for runners who love to dive into the details after they've been for a run and to be able to accurately track their progress over time.

It's not like Strava because I'm not including any social elements, intitally. And not like trainingpeaks because it's focused on individuals as opposed to teams or coaches. Also the analytics and models I offer are peronalised as opposed to one-size-fits-all. It's also running only. No cycling or anything else.

Ideal target market would be fairly decent amateur runners (e.g. sub 3 hour marathoners) who already know quite a bit about training but don't have a coach and are not good enough to be pro and have a full team doing this stuff for them. The pros have awesome tools but sadly most are not available for us mere mortals BUT I can build some of them! Example features:

1. Personalised "adjusted speed" models. The strava GAP model doesn't fit very well for me and many others, so I've made my own personalised model which gets updated each week. If you get better/worse at running up hills then model adjustments take that into account. The idea is not to provide a physiological correct model but more a performance based one.

2. I'm trying to do the same for surface types, heat and humidity as well. Of course these models are not personalised. I'll get to wind later on as it's much more complicated than the former. The idea is to have an accurate representation of "effort pace", which you can use as an input to performance models.

3. Using adjused pace data I will offer a pace/duration model to estimate critical speed/LT1/LT2/VO2max and this model forms the basis of tracking progress over time. Clearly most training wont be all out efforts, so I also estimate race performances based upon current fitness as well. E.g. if you ran X speed for Y time at a sub maximal effort then you can estimate what a maximal effort would be based upon the remaining aerobic and anaerobic power. From reading sports science literure, this is the most advanced way to track performance at the moment. The actual model I use is called an omniduration model.

4. I also have build some other models, e.g. Daniels running formula, which can be used but I don't find them to be as useful as the omniduration model.

5. I'm also trying to model how a workout or training session will effect your fitness. Where it's base/aerobic, threshold, VO2max or an anaerobic effect. Then, the idea would be to look at future training performance to assess whether the model was correct. You can then assess which types of training you respnd best to as well as which types of sessions you need to get the performance gains you need for your next race.

6. Specific race time predictor. Most platforms offer a single figure prediction for a distance but I want to offer specific race perdictions which take the course and weather into account. The model will give you splits taking all this into account.

7. Cohort adjusted performance models. How are you tracking against people your age? But more importantly, how are you tracking against people doing a similar volume and type of training to you? Are you improving at a similar rate?

There's a tonne of other stuff I can add but I'm going to keep it simple and focus on performance modelling for now because no-one seems to offer any decent tools around this at the moment.

If anyone found this interesting then I'd love to hear any feedback - let me know. Cheers!

Right now the boards, electronics, and firmware are in good working order. Although the routing is pretty YOLO.

It feels like there's a lot of unpleasantness going on in the world right now. I thought maybe I could put my other projects aside and try to make something that might brighten your day (It certainly has enough of LEDs).

A tree cutting tool.

Take photos of the tree from 6 different angles, feed into a 3D model generator, erode the model and generate a 3D graph representation of the tree.

The tool suggests which cuts to make and where, given a restricted fall path (e.g. constrained by a neighbors yard on one side).

I create the fallen branches in their final state along the fall plane, and create individual correction vectors mapping them back to their original state, but in an order that does not intersect other branch vectors.

The idea came to me as a particularly difficult tree needed to come down in my friends yard, and we spent hours planning it out. I've already gotten some interest from the tree-surgeon community, I just need to appify it.

Second rendition will treat the problem more as a physics one than a graph one, with some energy-minimisation methods for solving.

Its also not perfect since I haven't factored in rotation origin very well, and I'm now pursuing a far simpler physics-based approach

I was imagining something like this for pruning fruit trees — something to help noobs like me see how to put pruning guidelines into practice on a real, overgrown tree. Good luck!

chaosharmonic2• 1 year ago

Funny, one of mine also involves trees -- but is mostly outdoor cleanup. The kind that involves decades' worth of it, thanks to what I'll just say is a lot of maintenance that wasn't done over a long time. There's an extensive amount of brush, leaves, etc of varying ages that could maybe be shredded up into something useful, invasive vines I'm still trying to deal with, and more old trash than I've fully figured out how to properly dispose of.

It's turning into various DIY rabbit holes, actually, with the next one (outside of various related landscaping stuff) being to gut a basement.

defterGoose• 1 year ago

I would love to have such a model tell me how to prune my fruit trees as they grow up. Should be a fairly straightforward supervised problem with the right front end for the graph generation.

pbhjpbhj2• 1 year ago

When i read OP this is what I thought it was going to be - these branches are going to be apex competitors, these are crossing or going to cross, this one shows signs of disease, this one interrupts air flow through the centre, etc.

toss12• 1 year ago

You can start right now with an algorithm I learned from an expert when I was working in a landscaping business.

It is a very simple three-pass plan: "Deadwood, Crossovers, Aesthetics".

So, first pass, go through the tree cutting out only and all the dead branches. Cut back to live stock, and as always make good clean angle cuts at a proper angle (many horticulture books will provide far better instructions on this).

Second pass, look only for branches that cross-over other branches and especially those that show rubbing or friction marks against other branches. Cut the ones that are either least healthy or grow in the craziest direction (i.e., crazy away from the normal more-or-less not radially away from the trunk).

Then, and only after the other two passes are complete, start pruning for the desired look and/or size & shape for planned growth or bearing fruit.

This method is simple and saves a LOT of ruined trees from trying to first cut to size and appearance, then by the time the deadwood and crossovers are taken later, it is a scraggly mess that takes years to grow back. And it even works well for novices, as long as they pay attention.

I'd suspect entering the state and direction of every branch to an app would take longer than just pruning with the above method, although for trees that haven't fully leafed out, perhaps a 360° angle set of drone pics could make an adequate 3D model to use for planning?

In any case, good luck with your fruit trees — may they grow healthy and provide you with great bounty for many years!

boogieknite5• 1 year ago

i work in forestry software and am curious about your methods. is any of this open source? any intention on supporting growth modeling?

tetris114• 1 year ago

I plan for a time-bomb license (closed source for 10 years, make my money (if any), GPLv3 after that).

My methods are all over the place. Tree is taken as-is on the day, and cuts calculated on the fly, no future growth-modelling if that is what you're asking

postscapes1• 1 year ago

This is great idea - I have a huge tree in front yard that will either cost be $5-10k to come down or was going to rent lift and do it myself - A few particular branches scare me though in terms of how they will come down... Bonus points for where to tie things off.

emmelaich2• 1 year ago

Trees cost a lot of money to bring down. I've ideas for an automated cutter but it's a surprisingly difficult problem.

scandox• 1 year ago

Forgive my ignorance but all the tree cutting I've observed has been based on climbing and cutting in segments from the top rather than letting the tree fall. Under what circumstances is it better or necessary to actually let the tree fall?

shatnersbassoon• 1 year ago

IANAL (L=lumberjack) but it's clearly going to be cheaper if you can just chop it down, right? Quicker and less equipment required, less danger to life from having to climb and wield a chainsaw in an elevated position. Also, if you are interested in getting long planks out of the trunk, you would not want to cut it down progressively.

curmudgeon22• 1 year ago

I think it depends on how much space there is for the tree to safely fall. If there isn’t enough space to accommodate the height of the tree, it needs to be done in controlled segments.

beau_g2• 1 year ago

Any tree near civilization that someone wants to pay to cut down is likely going to be at a distance from a structure, powerlines, or pipes in the ground (that's also the reason they want it removed) where felling it as it lies is not likely an option which is why you see them sectioned down or done with a crane or bucket truck. A lot of these trees done by tree care companies in residential or commercial areas are also sprawling hardwood trees like oaks that can't always be safely just dropped from the ground even if there's a clear area to drop it in. For logging or wildland firefighting, most of the trees being dropped are straight growing softwoods like pine or fir that are just dropped from the ground (or by machine).

jwineinger4• 1 year ago

I was thinking of something similar during pruning season for my apple trees a few months ago. I even went so far as to take a scan of one of my trees with Luma and had it generate a 3D render of it. This worked surprisingly well, though it did take several days to get it rendered as it seemed their service was saturated.

My need/idea was to post that some where (r/backyardorchard probably) to get help in determining which limbs to prune. However, there didn't seem to be an easy way to share that sort of thing and time was of the essence, so I just forged ahead on my own.

rapjr9• 1 year ago

I've been thinking for years about a safer alternative to chain saws. Something along the lines of a carbide coated wire driven by an electric motor and battery. Strap it to the tree, turn it on, walk away and some minutes later the tree falls down. The main difficulty is in how to drive the wire. Using friction would create fast wearing parts. Maybe a chain could be used instead of a wire. It could oscillate back and forth, instead of having to be wrapped and spliced to form a circle around the tree. It seems really strange that no one has come up with an alternative to chain saws for decades (except for large scale trucks that can process whole trees.) For small trees and branches even a sawz-all is safer than a chain saw. Inspired by spending some time sharing a hospital room with a guy who had a chain saw accident, but I still haven't come up with a workable idea. Maybe someone else can.

tetris114• 1 year ago

We use a winch to guide the branches down, but would never apply the winch directly to the tree in case of whiplash when the branch finally breaks

jaredhallen• 1 year ago

I hear you on the safety angle, but chainsaws work really well. They're also very versatile.

beau_g2• 1 year ago

I was thinking I could use a tool just like the wire you described to remove a stump, after I spent 6 hours with a 5ton Bobcat trying to dig up a 3ft diameter pine stump to no avail today. For felling trees though, you need precise front cuts/back cuts to drop the tree at a desired angle, you can't just cut in one direction even if you have a cable attached.

downboots4• 1 year ago

Perhaps drilling in a wedge shape so it weakens the branch and it eventually breaks off naturally but it seems like more work than just a chain saw. The holes could also be used for steam treatment, enzymes [0] or something else to break it.

Surac2• 1 year ago

I use a tool called the Alligator. Is is a tool you can use like scissors. It has 2 chains on the inside of the the business ends. You put around the branch. Close the end and press the button. Springs will then close the end even more and cut the wood. No open chains

teleforce2• 1 year ago

Having joined may father and his friend during the process of cutting down big trees in the village neighborhood I can personally vouch that this indeed a cumbersome and very complex task for both the planning and the execution phases. However, for us the tasks are made easier by the trimming of the tree's branches since my father's friend is the expert tree climber.

From your descriptions, it seems that your tree cutting procedures do not involved precut of the tree's branches before cutting the tree down.

I've got the feeling that this cutting tree problem can be solved by constraint programming techniques [1],[2]. Alternatively generic tools for constraint programming, for example OR-Tools and MiniZinc can probably do the same if not better [3],[4].

https://undetectag.com I developed a device that turns an Airtag on and off at specific intervals. Current Airtags are detectable right away and cannot be used to track stolen property. That device allows you to hide an Airtag in your car, for example, and someone that steals your car will not be able to use some app to detect it. The Airtag will also not warn the thief of its presence. After some hours, the Airtag turns on again and you can find out its location. It’s not foolproof, as the timing has to be right, but still useful.

lyjackal• 1 year ago

An idea for more complete coverage: have 2 of them, and invert their intervals, such that one and only one is always on

pompidoo5• 1 year ago

Yes it's also a good strategy.

thruway516• 1 year ago

This will work for a while, before thieves know to check for multiple airtags. Better to not detect any in the first place

arjvik• 1 year ago

Is 4 on 1 off really the best strategy? Seems like it just makes it a 20% chance that the thieves detect the AirTag, right?

pompidoo5• 1 year ago

Due to its timing, the device is not suitable for stalking someone. Additionally, if you place it in someone's handbag, for instance, once the AirTag comes back online and the person starts moving, they will be alerted that the AirTag is tracking them.

Working on: Pantry Recipes – AI meal generation based on what’s in your kitchen

Over the past few weekends, I’ve been building Pantry Recipes – a mobile app that lets you quickly generate recipe ideas based on the ingredients you already have at home.

The idea is simple:

- Save or quickly select ingredients you have on hand - Tap Generate Recipes and get ideas instantly - You can also describe what you want to make free-form (e.g., "cheese omelette") and the app will generate a recipe for you.

The app is free for a number of recipe generations, then offers a low-cost subscription if you want unlimited use. It's live on the iOS App Store now: https://apps.apple.com/us/app/pantry-recipes/id6744589753

Happy to answer any questions if anyone’s curious about the tech, UX challenges, or what I learned from launching!

devsda• 1 year ago

Since you are using AI, what are the chances of your app suggesting existing recipes vs "inventing" new recipes.

Also, there can be set of ingredients that should not be mixed together or be cooked in certain way. Are these cases considered when generating recipes ?

sameline4• 1 year ago

Cool idea! I’m a big fan of AnyList so this was intriguing.

I think it could be useful to have a “recently generated” section in the Recipes tab that lets you find things you might have forgotten to save. Substitutions could also be a useful feature. For example, if I can’t find Mexican oregano, what else can I use?

graypegg2• 1 year ago

Really neat app! A button that says "instantly" and actually does the thing instantly already makes this better than every alternative! ;)

Maybe just an idea I think would be worth charging for to offset costs on yourself: if you could get a few accounts on different recruiting software packs (BambooHR, smartrecruiters, etc) and then let users test their resume with different recruiting software's AI filtering tools, that could help a ton of people. You'd have to make a lot of different job descriptions/postings in each one, but you could probably craft them all generically enough to fit most careers.

Once that's going, maybe a pay-per-use fee to test your resume that gives the paying user a couple unique recruiting links to a few job postings, and then use playwright or something to capture screenshots of their profile in the backend(s).

Oras4• 1 year ago

Thank you! I appreciate the kind words.

I like your idea, but its hard to implement due to privacy concerns and could violate the ToS of these platforms (for sharing the account).

But I do have a feature in mind to do something similar. My plan is to always keep it free, with any feature, but I have to think of monetisation. Right now, it would be charging employers/job boards instead of job seekers. I've been there, the job search is stressful enough to add financial burdens.

I am working on making it easier to learn languages. We provide a platform for teachers and educators to create their own language courses. The platform offers features similar to software like Babel or Anki, along with some unique features for phonetics study and customizing the learning experience.

We're currently working with language influencers to build courses on Emurse. This year, we launched Japanese Phonetics course created by the YouTuber Dogen https://emurse.io/course/japanese-phonetics.

If you want to try out Emurse, we have a free Thai reading course available. You can view the first lesson without out creating an account: https://emurse.io/courses.

I am working on a curated database of proxy IP addresses frequently used by bots: https://deviceandbrowserinfo.com/product/proxies-ips

So far I have ~ 3M distinct IP addresses per 30 days, with a lot of fresh proxy IPs, 1.7M. The DB contains only verified IP addresses through which I've been able to route traffic. It DOESN'T rely on 3rd party/open-source data sources.

I also made an open-source proxy IP block list based on the data: https://github.com/antoinevastel/avastel-bot-ips-lists

Havoc3• 1 year ago

Wouldn’t this end up flagging a lot of residential IPs due to residential proxies?

avastel3• 1 year ago

The DB contains different types of proxies: - Residential - ISP - Data center

I don't include mobile proxies since they're heavily shared, so knowing that an IP address was used as a proxy at some point is basically useless.

Regarding your remark, indeed, there are several shared residential IPs, including IPs of legitimate users who may have a shady app that routes traffic through their device. That's why I don't recommend blocking using IP addresses as is. It's supposed to be more of a datapoint/signal to enrich your anti-fraud/anti-bot system. However, regarding the block list, I analyze the IPs on bigger time frames, the percentage of IPs in the range that were used as proxies, and generate a confidence score to indicate whether or not it is safe to block.

Working on a database compatibility tool. So your app works on SQL Server 2022 on-prem, but does it work on Azure SQL DB, AWS RDS, GCP CloudSQL, etc?

These cloud flavours have a compatible SQL dialect, but it's often details like missing features (CDC and Auditing on RDS are good examples) or differences in system objects that make it difficult to support your app on these platforms.

I capture all sql statements, run them through multiple SQL parsers to find all the system objects your app is using (tables, functions, stored procedures, etc). I then check them all against a catalog I have built of all system objects for every version of SQL Server on every platform.

I then give a report to see which platforms your app will work on, which ones it wont work on and which system objects are the problem.

Other database engines will be added once I get it working end to end (almost there).

cgadski• 1 year ago

In little bits of free time I get here and there, I've been working on using reinforcement learning to build some better bots for my favorite multiplayer game. Project is up here: https://github.com/cgadski/autotude

So far all my work has gone into the technical side of setting up the game (a Java app written in 2010) to work as a reinforcement learning environment. The developers were nice enough to maintain the source and open it to the community, so I patched the client/server to be controllable through protobuf messages. So far, I can:

- Record games between humans. I also wrote a kind of janky replay viewer [1] that probably only makes sense to people who play the game already. (Before, the game didn't have any recording feature.)

- Define bots with pytorch/python and run them in offline training mode. (The game runs relatively quickly, like 8 gameplay minutes / realtime second.)

- Run my python-defined bots online versus human players. (Just managed to get this working today.)

It took a bunch of messing around with the Java source to get this far, and I haven't even really started on the reinforcement learning part yet. Hopefully I can start on that soon.

This game (https://planeball.com) is really unique, and I'm excited to produce a reinforcement learning environment that other people can play with easily. Thinking about how you might build bots for this game was one of the problems that made me interested in artificial intelligence 8 years ago. The controls/mechanics are pretty simple and it's relatively easy to make bots that beat new players---basically just don't crash into obstacles, don't stall out, conserve your energy, and shoot when you will deal damage---but good human players do a lot of complicated intuitive decision-making.

Planes will "jump around" when they're not close to the objective---the server sends limited information on planes that are outside the field of vision of the client, but my recording viewer displays the whole map.)

Critic (https://getcritic.dev) - An improved inbox for GitHub pull requests

The experience with GitHub can be terribly frustrating when it comes to managing the stream of incoming pull requests. The default inbox and notification systems are not so good, and not flexible. Critic allows to create any number of sections, each section being defined by an arbitrary search query.

Lighthouse (https://lighthouseapp.io/) - a different take on RSS readers, focusing on inbox zero

RSS readers show content based on the feed they're coming from, and show read and unread items in the same list. That makes it difficult to know which items you've already seen, and is especially annoying for managing items that you want to read at some point but not anytime soon.

Lighthouse splits it into Inbox (new items) and Library (bookmarked items). This makes it possible to process new items quickly, and take your time with reading them.

Three Kind Words (https://threekindwords.com)

It’s a small vending machine on the internet where people anonymously send a friend three postcards, one word at a time. The first two cards are unsigned, and the last one reveals who sent them. It’s meant to be a slow, kind surprise in the mail.

I shared this on HN a while back, and it gave us a quiet little push. Since then, we’ve sent 246 out of the 300 postcards we set out to deliver this year. Things have slowed down lately, but the whole thing is automated, costs almost nothing to run, and has been a lot of fun to work on!

stevage3• 1 year ago

Just some feedback, I think this would be much more compelling with better choices of messages. It feels like the first two words are setting something up and the third should have some kind of payoff, but a lot of the messages don't work like that. The third word is usually predictable and obvious and something of a letdown "Never give....up".

There's really nothing in that list that is interesting enough to send to anyone in my life. I'd be wanting to send something very specific like "Remember cycling Iceland?" or "Soy chicken success" or something.

I get your concerns about "writing something inappropriate" but you could probably let people choose 3 words from a list of a few hundred pre-vetted words?

Creating stealth group in a huge Fortune 500 company with the blessing of my immediate boss but no other higher-ups. Trying to productize critical consulting tool sets in the utility industry so we can stop repeating ourselves for the 100th consulting engagement.

Yes, customer is a special snowflake but they still need 90% or whatever every other client in this industry needs.

Feeling increasingly like this is a fools errand.

Even though we've proved this out with tool sets strung together with duct tape and safety pins, and are therefore the most profitable group within our department, we still need to be 100% billable.

A note taking app - I know, I know, been done a billion times. But really, no software I’ve found works the way I want it to, so I’m just trying to write my own, starting with a front-end agnostic core and a TUI.

If it strikes a chord with anyone, I’d love to collaborate! The concept is centered around organization bubbling up naturally from dumping info in with tags, and “typing” your tags so that when you go to a tag’s page, the layout is customized based on what it is - a project, person, etc. A project could have all relevant tasks and notes listed, whereas a person might have name, contact info, etc.

https://github.com/weakphish/yapper

weakfish2• 1 year ago

Expanding some - the tags concept is similar to AnyType[0] types, but the rest of the software I’m writing is more oriented towards dump-first, tag, and let it sort itself out, whereas AnyType requires careful management and configuration of the workspace.

Premium tooling to work with JSON Schema (https://www.sourcemeta.com).

I'm a member of the JSON Schema Technical Steering Committee, and been making a living consulting with companies making use of JSON Schema at large. Think data domains in the fintech industry, big OpenAPI specs, API Governance programs, etc. The tooling to support all of these use cases was terrible (non-compliant, half-baked, lack of advanced features, etc), and I've been trying to fix that. Some highlights include:

- An open-source JSON Schema CLI (https://github.com/sourcemeta/jsonschema) with lots of features for managing large schema ontologies (like a schema test runner, linter, etc)

- Blaze (https://github.com/sourcemeta/blaze), a high-performance JSON Schema C++ compiler/validator, proven to be in average at least 10x faster than others while retaining a 100% compliance score. For API Gateways and some high-throughput financial use cases

- Learn JSON Schema (https://www.learnjsonschema.com/2020-12/), becoming the de-facto documentation site for JSON Schema. >15k visits a month

Right now I'm trying to consolidate a lot of the things I built into a "JSON Schema Registry" self-hosted micro-service that you can just provision your schemas to (from a git repo) and it will do all of the heavy lifting for you, including rich API access to do a lot of schema related operations. Still in alpha (and largely undocumented!), but working hard to transition some of the custom projects I did for various orgs to use this micro-service long term.

As a schema and open-source nerd, I'm working on my dream job :)

nathan_douglas10• 1 year ago

That's really neat. I've been doing some JSON schema work on our products recently, especially trying to take a schema and generate info compliant with the schema for e.g. testing accounts with clean data on non-production environments, etc. I feel like the area's underdeveloped.

Yeah, exactly. This is a great example. In theory schemas open up all of those use cases in an elegant manner, yet the tooling often sucks. Would love to connect and at least have your use case on my radar!

Colibri—a self-hostable web application to manage your (and your family's) ebook library, intended as a companion to Calibre. I want it to be a friendly, simple, capable, opinionated app to review your books, add metadata to them, get them onto your reader, share them with family and (few) friends, create a public shelf for bragging, connect with Goodreads etc., and exchange comments and reviews on books.

This is explicitly not intended to ever be monetised, and I enjoy all the implications that has on the design. Colibri is as much a tool I personally want to use, as it is a study in small-audience user interfaces, and the quest to build the perfect book catalog schema.

I'm looking for fellow book-loving people to work on Colibri, to create the best personal digital library possible. If you're interested, feel free to reach out via email (in bio), or on GitHub.

Ebooks in an S3 compatible storage bucket, metadata in a Postgres database. That has the huge advantage of being able to do full text search and kNN similarity right in the database, for example.

Colibri is built around a pretty solid data schema (I hope). Check out the migrations folder if you’re curious :-)

Great stuff, has been meaning to create an online library of my burgeoning ebooks collections for quite som time now, this is exactly what the doctors ordered and it's based on Postgres.

Just wondering about the encrypted collection of ebooks from Kindle for example. Are these ebooks supported and does it only supports metadata, what about the content search for these ebooks?

9dev7• 1 year ago

So, Colibri is intended to be a companion to Calibre, maybe do like 80% of what it does, but not all of it. Also, I want Colibri's core to have a fully clean collar: It handles your personal books, but will not be able to automatically de-DRM books and such. However, the way book assets work, you're of course free to just attach an encrypted AZW3 file to a book!

Are these ebooks supported and does it only supports metadata, what about the content search for these ebooks?

Have you seen https://github.com/colibri-hq/colibri/issues/45? Content search is planned, but requires access to a book's text content, obviously. My recommendation would be to use Calibre to strip DRM and convert the books to epub/mobi files, and import those to Colibri; this has the general benefit of ensuring access to content you bought without depending on Amazon's good will :-)

I'm working on an unified MCP server that can search and use a large number of tools. The current way of using MCP server (adding each MCP server directly) simply doesn't scale. If your AI agent needs to use 100 tools, you need to manually configure a lot of MCP servers. And when you feed those tools to the LLM, it may get confused and tool calling accuracy starts to drop.

This is why I'm building a unified MCP server with just two meta tools: - Search Available tools - Execute a tool

When I want to send an email, I ask LLM to use the Search Meta tool to search for Gmail related tools in the backend, then the meta tool returns the description of relevant tools. The LLM then uses the Execute meta tool to actually use the gmail tool returned. https://github.com/aipotheosis-labs/aci

I just put live a daily logic puzzle, Clues by Sam. I've been working on it for a while now, mainly on the level generator. It was tricky to generate levels that are solvable using logic (no guessing needed), and also fun to solve (no crazy long deduction chains, but also not just obvious things). I'm sure the implementation still has some quirks on some devices, so would love to hear if you encounter issues!

sxv2• 1 year ago

Highly enjoyable (after I finally read the definitions of "neighbor" and "to the right/left")! Did you write a program that can automatically generate these?? I'll definitely try this again. Note, the emoji graphic in "share" might be buggy? I'm seeing one green checkmark, one green square, and four red squares..

tikotus11• 1 year ago

Thank you so much for trying out the game and taking the time to write the feedback!

I did! That was the main workload of this project, and is still ongoing. I have ideas for improvements, and I also have to fix some sentences manually sometimes. But it's getting there.

The sharing shows a kind of "health bar". Every time you make an illogical guess, it reduces one. Running out of "health" doesn't prevent you from completing the puzzle, but it does show up in your share. Based on this, you made 4 "illogical" guesses. If you didn't, then there's a bug. But feels like I should anyways clarify this, if it wasn't clear to you. Thanks again!

mgkimsal• 1 year ago

frustrating. i eventually just clicked every single one, and keep getting the "This choice can't be made based on pure logic" message. maybe i'm just dumb...

tikotus11• 1 year ago

You might be misinterpreting what "neighbor" means or what "to the left" means. There is always at least one choice that can be made logically. If the logical choice is, say, that Jess is innocent, and you say Jess is a criminal, the game won't let you do that choice. Maybe that's what happened to you?

jwineinger4• 1 year ago

swatcoder• 1 year ago

This is great, but the need for a long glossary of terms is a sign that you might want to keep tuning language/word-choice.

As you've seen in replies here already, many term choices you've made have enough variety in how they're conventionally used that people incorrectly assume they know what it means only to see the "nope!" popup when they try to apply it. That frustration is going to spoil first impressions of what actually seems to be a really great puzzle system, which is a shame. The more you can reduce that experience, the less likely you'll be to prematurely burn off players.

A good measure for getting it right would be that you don't even need a glossary at all, or that you can get it so condensed that you can make it more prominent without becoming distracting.

Alternately, you could maybe use symbols instead of words to represent your rules, as more players would intuit that they should learn the symbols before making (wrong) assumptions.

tikotus11• 1 year ago

This is great feedback, and I think you're spot on. It's been really challenging to find wording that is brief enough, but also specific enough. I hope it's something I can improve in the future as I keep exploring new ways of giving hints. The idea of using symbols is interesting, hadn't considered that!

After getting frustrated by the game not accepting my responses to the obvious clues repeatedly I resorted to clicking on each person and selecting both Innocent and Criminal.

- "Barb and I have one innocent neighbor in common"

- Implies Gary is a criminal

But the game won't let me.

Thank you for taking the time to go through this. The hint should be clarified. It means "somewhere to the left", so on the same row to the left. It is either Freya or Gary since they are both to the left og Harold, and common neighbors of Barb and Cheryl. You have no way of knowing which one yet. This will be clarified in future puzzles.

_nivlac_• 1 year ago

I really enjoyed this! I can't even comprehend how levels can be generated for it. After reading instructions I found it straightforward to play.

FYI there's a misspelled word - "accountat" on the home page.

tikotus11• 1 year ago

Awesome! Thank you for playing! And well spotted, will fix!

The process of generating levels is based on constraint solving. For now I'm not going to say much more about it, since it's the most innovative and valuable part of the project.

WA• 1 year ago

Really good game. I liked that you can't guess your way to success, but must solve it logically. I found the terminology ok after reading it.

tikotus11• 1 year ago

Great to hear! Preventing guessing was a critical step to make this concept click. Accidentally making an illogical guess (be it right or wrong) felt like it ruined the rest of the puzzle, since it spoiled the intended solve path. Happy to hear positive feedback on the choice!

I'm building an MVP for an "AI bedtime stories" app. The idea is that you just input the character names, a theme, and choose a voice (including the option to clone a parent's voice for narration). It generates a story and reads it out using TTS.

There are already a few services like this, but most don't support using a parent's voice, and very few can connect stories together into a continuous narrative based on previous ones. Also I would like to hold context for fairy tales kinda local. For example Polish folklore is different than British. Most common villains are different and it can be fun and educating problem to solve.

I'm mainly doing this as a learning project, but curious to see where it ends up.

fxtentacle• 1 year ago

I'm trying to figure out how I can turn hobby products (that me and family and friends are using) into real products for a wider audience. So far, I've found 2 main failure cases:

1. While I can share source code and documentation with trustworthy people, that won't work at scale: the market would get flooded with Chinese clones that re-use my Open Source software but then I have no ongoing revenue to fund support / maintenance.

2. Especially for products with a physical component, shipping, taxes, refunds, CC chargebacks etc. add considerable overhead. Plus I need to add in Amazon fees and marketing spend. And suddenly I need to charge 8x the manufacturing price, which means I either need to massively cheapen out with quality, or it's going to be a very premium product.

I’m working on Popgot (https://popgot.com), a tool that tracks unit prices (cost per ounce, sheet, pound) across Costco, Walmart, Target, and Amazon. It normalizes confusing listings (“family size”, “mega pack”, etc.) to surface the actual cheapest option for daily essentials.

On top of that, it uses a lightweight AI model to read product descriptions and filter based on things like ingredients (e.g., flagging peanut butter with BPA by checking every photograph of the plastic or avoiding palm oil by reading the nutrition facts) or brand lists (e.g., only showing WSAVA-compliant dog foods). Still reviewing results manually to catch bad extractions.

Started this to replace a spreadsheet I was keeping for bulk purchases. Slowly adding more automation like alerting on price drops or restocking when under a threshold.

KerryJones3• 1 year ago

I like this idea a lot -- feels like there's a lot of room to grow here. Do you have any sort of historical price tracking/alerting?

And/or also curious if there is a way to enter in a list of items I want and for it to calculate which store - in aggregate - is the cheapest.

For instance, people often tell me Costco is much cheaper than alternatives, and for me to compare I have to compile my shopping cart in multiple stores to compare.

mynameisash3• 1 year ago

For instance, people often tell me Costco is much cheaper than alternatives, and for me to compare I have to compile my shopping cart in multiple stores to compare.

A few years ago, I was very diligently tracking _all_ my family's grocery purchases. I kept every receipt, entered it into a spreadsheet, added categories (eg, dairy, meat), and calculated a normalized cost per unit (eg, $/gallon for milk, $/dozen eggs).

I learned a lot from that, and I think I saved our family a decent amount of money, but man it was a lot of work.

I'm so glad you like it!

We have historical price tracking in the database, but haven't exposed it as a product yet. What do you have in mind / what would you use it for?

unvalley2• 1 year ago

Cool! I hope it's coming to Japan (I live) near future.

mynameisash3• 1 year ago

I like that you have the ability to exclude on some dimension (eg, I don't use Amazon.com). Do you have or are you considering adding more retailers beyond the four you mentioned? For example, I buy a lot of unroasted coffee from sweetmarias.com, and excluding Amazon from Popgot results eliminates all but one listing (from Walmart).

juxtaposicion6• 1 year ago

Ah, hell yeah! My buddy on this project has been itching to add sweetmarias.com ... he just needed this as an excuse.

So yeah, we'll add it. If you shoot me an email (or post it here?) to chris @ <our site>.com I'll send you a link when it's done. Should take a day or two.

abdullahkhalids2• 1 year ago

I don't think I have the time to go to different stores to buy different things based on what is cheap. I have one fixed one.

However, what I would like is a product where I upload my shopping receipt for a few weeks/months from the one store I go to. The application figures out what I typically buy and then compares the 4-5 big stores and tells me which one I should go to for least price.

juxtaposicion6• 1 year ago

Yeah, I agree. It is a pain to search product by product instead of sticking to one store. Also popgot.com can only do what's online & shipped to you -- so really just the non-perishables / daily essentials that are not fresh groceries. But even when limited to consumables I save ~$100/mo by basically buying by unit price.

Uploading a receipt to see how much you can save... that's a good idea. I think I can find your email via your personal site. Can I email you when we have a prototype ready?

amelius• 1 year ago

This is a great idea. And OCR should be good enough nowadays to parse the receipts. Probably would work best as a mobile app, though.

cwackerfuss• 1 year ago

God tier filtering. Do you mind sharing how you integrated AI into the filter system? Your "flagging peanut butter" example also makes me wonder if the LLM is tagging the product with a large number of attributes on each run so it's not prohibitively expensive.

noahbp2• 1 year ago

This is so good I disabled my ad blocker.

Thank you. Seriously.

Note: I searched "Protein bars", and it treated all protein bars equally. The 1st-20th cheapest had <15g of protein per bar. I had to scroll down to the 50th-60th to find protein bars with 20g of protein, which surprised me for being cheaper than Kirkland Signature's protein bars.

Awesome site. You've probably come across it, but just in case you haven't. In the UK we have trolley.co.uk (plus app) which is handy. The barcode scanner I use a lot when I want to check if the branded product is a good price in the shop i'm standing in or if i'm getting ripped off. They have all products (I assume because online grocery shopping is bigger here?). Personally, I'm looking to start online shopping (new dad so time poor), it'd be great if I could build a shopping list and a site tell me which online grocer to order from for the best value, with basket price breakdown for each.

A custom Python/Django based mini-app (mini — at least for now) that will allow me to import transactions sanely and safely to my local GnuCash install.

I’ve been doing tedious manual entry for a bit over two years now and after having missed three consecutive months, the only other option was to bail.

As a start it should help with 3 main things:

- Translation, categorization: my source documents aren’t in English but my GnuCash entries are. This is one of the reasons I don’t use the built-in imports. (This should shave off at least 90% of time spent entering data)

- Human-error prevention: there were at least 5 times where it took me over 15 minutes to reconcile a discrepancy because I entered some number or some account wrong somewhere.

I've implemented input and output "drivers" for Windows and Linux: WASAPI, ALSA, Windows Raw Input, and evdev.

Soon I'll start work on Lua bindings. The idea is to configure the core engine programmatically. Hook up inputs, modify synth parameters, route output.

Not world altering but shockingly underserved market. With few players who raised money and therefore have to price expensively, whereas as a bootstrapped side-hustle we can offer it in a flat-fee way that doesn’t “penalize” growth by charging per-user or for inactive users.

I realized after trying multiple tools like Supabase and Firebase, I really need to program my own solution. I don't need a bunch of *Enterprise* level features. I just need to read the card data from a database, and process the games with some simple server side code.

I hope to have the server, along with a basic front end done by this summer. Then it'll be released under a permissible license. Probably MIT.

I want a community of different front ends compatible with the same server. I suspect a straight up cli client without a bunch of effects might be popular with some of y'all.

If you want to code a frontend in Unreal, the server doesn't care. The game remains the same.

A few things:

- Snapshot (https://apps.shopify.com/snapshot): AI generated product photos for Shopify. Previously used Flux and Stable Diffusion but always had quality problems. Was very tricky ensuring text remained the same and the product fit into the generated background. Just integrated the new OpenAI image generation model and results are much better however their masking feature doesn't work properly so need to wait for them to fix that before I can offer the same feature of keeping text/fine details the same

- Lurk (https://apps.shopify.com/lurk): New one I just launched - allows Shopify merchants to track the prices of competitors and adjust their own in response with dynamic pricing rules. It's cool because you just have to paste a URL and it uses AI to figure out the price. Again, there's a surprising amount of things you need to figure out to make this work reliably at scale (e.g. popups, ambiguous HTML, location-based pricing, etc.)

hacking a illegal gamble website

matt_heimer3• 1 year ago

It tried out vibe coding this weekend. I've been using AI to get smaller examples and ask questions and its been great but past attempts to have it do everything for me have produced code that still needed a lot of changes.

I hit an OpenSearch bug this week where you can't get any browser based requests to work. Its due to zstd becoming a standard part of Accept-Encoding and OpenSearch not correctly supporting it so I wanted to install a browser plugin that modified the browser HTTP request headers to my servers.

I don't know about everyone else but I love that browser plugins are possible but I hate having to find them. Its mostly due to never knowing if you can trust a plugin and even if you find one, you have to worry about it being bought out in the future. With vibe coding I was able to build a browser extension in 45 minutes that had more features than I originally planned for.

I spend more time documenting the experience than building which is wild. If you are interesting you can look at the README in https://github.com/mattheimer/vibe-headers

But I left the experience with two thoughts.

Even seasoned developers will be using vibe coding in the future.

I think in the near future the browser plugin market will partially collapse because eventually browsers will build extensions themselves on the fly using natural language.

So there is no technical debts ?

matt_heimer3• 1 year ago

That's a difficult question to answer because I don't know if I'll grow the extension in the future. Only time will tell.

After I completed the extension I did try on another model and despite me instructing it to generate a v3 manifest extension, the second attempt didn't start with declarativeNetRequest and used the older APIs until I made a refinement. And this isn't even a big project really where poor architecture would cause debt.

Vibe coding can lead to technical debt, especially if you don't have the skills to recognize that debt in the code being generated.

nonethewiser4• 1 year ago

In my experience, "vibe coding" can produce a rich prototype very fast.

Then as scope expands you're left with something that is difficult to extend because its impossible to keep everything in the LLM context. Both because of context limits and because of input fatigue in terms of communicating the context.

At this point you can do a critical analysis of what you have and design a more rigorous specification.

falcor84• 1 year ago

But my reading is that the parent wouldn't have tackled this at all without the vibe coding, and would have used an off-the-shelf extension. So in that case, it's a pure win, no?

I don't disagree but context limits are expanding rapidly. Gemini 2.5 Pro which was used here has a 1 million token context window with 2 million coming soon. Cost will be a concern but context size limits will not.

If your project is well organized and individual files are small and the dependency graph isn’t too crazy, Claude code does an amazing job building only the context it needs even as the project grows. You just have to be aggressive about refactoring for maintainability. The bonus here is that it’s easier for humans to work on too.

I've always been into MUDs since the mid-90s and every now and then I get this idea to write one from scratch (again) and I get pretty far and then I lose interest.

The new one is browser based.

The mud engine runs in a web worker and takes advantage of some of the modern web tricks to do stuff. For instance, data files (think: area files that don't change often) can be stored remotely and then cached with a service worker. This allows the MUD to run offline. But that's only fun if you're playing solo.

IO between the UI and worker is handled by message passing.

Multiplayer is handled by the MUD opening an outbound connection (probably websocket) to a connection collector host. Other players would then connect to that host and have their IO routed appropriately. The host can even be smarter: it could be a specialized Discord client, allowing users to play from there. Firebase may also be involved. I don't know.

The important bit is that this is still basically message passing, so the engine won't need to know the difference between the local user and a remote user.

The MUD database would be an IndexedDB. Probably. I haven't thought as much about that yet.

I am sure all of this is theoretically possible, at least.

nonethewiser4• 1 year ago

IndexedDB seems really cool. Never really worked with it but seems like a good option for you.

nathan_douglas10• 1 year ago

YES! Another MUD programmer! I started writing one in Meteor about eleven years ago. I don't even know if Meteor's still a thing anymore... I've had a few projects in Rust that were mixtures of roguelike and MUD models, conceptually. I usually got aggravated with the models I created, though.

I really like your multiplayer idea. That sounds really clean and flexible.

AI bookkeeping for solopreneurs.

As a freelance web dev who also has an Airbnb side hustle, I got tired of expensive bookkeeping for a few transactions per month. I tried DIY, but my time is worth more than that.

Most importantly, both pros and DIY got subtle things wrong and caused me to miss out on thousands of dollars in deductions and credits.

So I’m making an AI bookkeeping chatbot that will handle all that for me. The aim is full automation while surfacing tax deduction and credit opportunities throughout the year. Like wouldn’t it be awesome to just have the research and tax credit or do home office deductions with zero effort?

At the end of the year, Kumbara puts together a series of financial reports that you plug into your tax software or hand to your CPA.

Working hand-in-hand with CPAs and some platform partners on this. Would love to hear from other solopreneurs or engineers who want to help build the future of financial freedom.

I'll keep this in bookmark.

I procrastinate on taxes for the silliest of reasons: I don't want to spend the time to create a P&L for my side gig to give to my accountant. Takes less than an hour but it is just annoyingly tedious.

All my income and the majority of my expenses are done through PayPal because I want to minimize the bookkeeping effort. For some unknown reason, they don't have an annual P&L statement as a standard report. This year I tried a bunch of things with Copilot using PayPal reports. The most eye-opening result was that I could give it a .csv file with all my transactions for the year and tell it to generate a P&L statement with expense categories. It managed the task almost flawlessly. The only cleanup I had to do was to recategorize a couple of items. To say that I was blown away is an understatement.

I'm working on a human-like AI opponent for VR table tennis. It's something I really want myself, love playing table tennis in VR, but with online play you get the latency issues, people that have adopted a playing style which basically hacks the game physics or other aspects, or people who are just plain rude. Playing against the AI is much nicer, but it's not varied or realistic enough such that when you actually play against real people you are ill prepared.

At a very early prototyping phase, but having a ton of fun. https://x.com/artofpongfu

I'm also building a simpler soft heap.

Working on a browser extension to make it easier to find content on YouTube that fits your interests.

I watch a lot of YouTube videos and have found it very annoying that YouTube latches onto one or two topics that you've watched and only recommends that type of content over and over again. Even if you use their "Not Interested" tool, not a whole lot changes in your recommendations.

At the end of last year I launched Relevant - a crowdsourcing website where users can categorize the channels they watch into a defined hierarchy of categories ranging from broad topics like "Science" and "Gaming" to more specific ones like "Phone Reviews" or "Speedrunning".

Although I've had good feedback on the website, engagement has been relatively low and I think that's because it's a big ask to have someone navigate to the website to find the content. This year I decided that I'd bring the content to them by making a Chrome extension that lets users interact with Relevant directly from within YouTube.

It's still a work in progress but I'd love to get a first version out within a month or so to start spreading the idea and gathering feedback. If this is of any interest to the people here on HN then please let me know what you'd like to see most on your feeds.

I strongly, strongly recommend adding video essays as a category as well - they're very big now.

redbackthomson4• 1 year ago

Yeah absolutely! The category list is meant to be dynamic as the industry changes and new forms of contents crop up. I can't stay on top of it myself, so I'm always looking for suggestions/maintainers from anywhere.

If you have a look at the category tree, where do you think video essays would go in that?

Timwi2• 1 year ago

Hm, I tried to contribute, but it asked me to categorize a channel I've never heard of (DefendTheHouse) and no matter how many times I click “skip” it keeps going back to the same one.

I also notice that you first said “browser extension” but later you said “Chrome extension”. Are Firefox users going to be out of luck?

redbackthomson4• 1 year ago

Hmm that's strange. Perhaps you have two Google accounts with different subscriptions? When you sign in I grab your subscribed channels and that's what I send when you categorise. You can check the "Subscriptions" page to see exactly what data we pulled.

I did say Chrome browser because with the deprecation of manifest v2, I had to make a choice about which to support. I decided given Chrome's larger market share that it would benefit the most people sooner. However I'm building it in such a way that porting to Firefox shouldn't require much additional work.

AI has taken over the hype in sales and go-to-market strategies. But for independents, solopreneurs, professionals, and many founders or CEOs, relationships and partnerships are still central.

I think sales will bifurcate: either fully automated self-sale, or fully relationship based. All of the major CRMs (customer relationship management) software are going all in on AI and sales automation.

I think relationship sales is going to see an increase in comparative advantage. I've always been a relationship seller but the current crop of CRMs are not designed for me. So I've built https://humancrm.io/ to scratch my own itch.

jobswithgptcom2• 1 year ago

I’ve been working on a side project called jobswithgpt — after months of building and refining, the first version is finally live: https://jobswithgpt.com

The idea is simple: a job search site that actually works for job seekers. It focuses on listings posted directly by companies (no spam, no middlemen, no bloated sponsored posts drowning out real opportunities). It uses AI to surface better matches, recommend jobs intelligently, and pull out the most important info from job listings automatically. You can also bookmark jobs you’re interested in and track them easily — no signup needed unless you want personalized suggestions.

It’s still early, and we’re improving it constantly. Would love for you to check it out, try a search, and let me know what you think — good, bad, rough — all feedback helps. Thanks a lot for the early support!

Main work: tokenization of real-world assets, but on the side I’m building two projects as a solo dev:

  - XRoll.io — a fully on-chain gaming framework on the XRP Ledger, inspired by SatoshiDice but built for compliance. Commit-reveal fairness (HMAC_SHA256(secret, bet_txn_hash)), full transparency on-chain. Integrated KYC, AML, self-limits at the protocol level. Frontend is optional; ledger is the source of truth.

  - Nexula — an evolutionary image generation system. Embeddings extracted with CLIP, clustered via HDBSCAN, visualized with UMAP. User behavior (time spent) drives fitness scores; top samples recombine through weighted interpolation to generate new images. Built on Django backend, session-based personalization without login.

Looking for like-minded people interested in exploring both the technical and business sides of these systems.

Currently building a CORS Proxy.

After working on it for a while, I noticed there’s a stigma around using CORS proxies, often associated with fetching undocumented APIs.

While that’s sometimes true, I’m hoping to change that perception, to show that they can also be used for accessing real APIs. It just requires the proxy to correctly handle credentials and secrets.

The idea is to open up more possibilities for building static-first apps without worrying about CORS.

Some music control using Wii balance boards thing: https://gitlab.com/TOGoS/SG-P27

So far this has means orchestrating a set of processes just to talk to bluetoothd, automatically connect to boards, guess which /dev/input/event* device each one is associated with, and start reading those and sending data somewhere over OSC. Every step of the process is about 10 times as difficult as I initially expected it would be, which is why, after months of work, I'm still putzing around with process orchestration instead of actually doing anything with music.

The bit of hair on this yak that I'm currently shaving is building a TUI library for Deno so that I can build a nice dashboard for keeping tabs on the state of all the different pieces. I prototyped a bit of the orchestration process in Node-RED, which was neat, but not exactly what I'm going for. There is a TUI library for Deno already, but it's kind of buggy and non-ergonomic for my brain.

rubb3rDucc2• 1 year ago

so I'm working on side project to make managing and exploring your music library easier.

The idea is you can set a few filters (like bpm, key, decade, genre) and then swipe through random songs, accept or reject them for inspiration or playlists. Kinda like Tinder but for digging through your own tracks.

It also tracks what's trending on TikTok/YouTube/SoundCloud weekly, so you can find stuff that’s blowing up, filterable by region. Plus it can build smart playlists automatically based on rules you set (like “new 90s house under 120bpm” every month).

It is just a tool to make working with your existing local/Apple/Spotify/SoundCloud library faster and more creative.

Here's a demo of it: https://filtered-f.web.app/

Working on supporting MCP (model context protocol) in my LSP (language server protocol) proxy: https://github.com/noredeen/lspwatch.

I wrote this tool to make instrumenting language servers very easy. MCP (both protocol and architecture) seems heavily inspired by LSP which made me curious about what it would take to support it through my telemetry-capturing proxy.

Haven't thought too deeply about how useful an MCP proxy can be but I see it as potentially a general platform for monitoring or debugging MCP servers or clients.

isaacphi2• 1 year ago

Super interesting! I'm also working on something related to MCP and LSP: https://github.com/isaacphi/mcp-language-server it's an MCP server that runs a language server.

Do I understand this properly, you're building a telemetry tool for MCP similar to your telemetry tool for LSP, or is it something else?

noor_z2• 1 year ago

Yup exactly. My tool is supposed to sit between MCP clients and servers. For now only stdio is in scope. Your tool is great. An MCP server for LSPs! I'll be taking it for a spin.

I am about to begin a PhD in astronomy. Until last month I was working at Caltech for 3 years on code which calculates orbits of asteroids to high precision.

I was allowed to open source it and I am planning on making it the basis of my PhD research:

https://github.com/dahlend/kete

It can predict the location of the entire catalog of known asteroids to generally within the uncertainty of our knowledge of the orbits. Its core is written in rust, with a python frontend.

Last month, I started playing around with code sandboxes and how LLMs might interface with them and wrote a little blog post about it [1]. I then took the code and vibe coded my way to a multi-tenant (untested!) sandboxing server that lets you run arbitrary Docker containers and provides a simple HTTP interface and UI. A cute, novel idea is that you can fork containers easily, as seen in the video in my repo:

https://github.com/ammmir/sandboxer

It may not be useful, but it's been fun, and I've honed my gut-level experience in Docker, Podman, Linux namespaces, Checkpoint/Restore, CRIU, and more. The ultimate goal is to hand each AI agent iteration a sandbox of its own (forked from the previous iteration), and have it build apps in private sandboxes. You'll be able to view intermediate progress as the app is being built (or failed rabbit holes), since each sandbox gets a unique URL automatically. Like, imagine if each commit of your git repo had its own URL to preview the app!

Working on designing and building an interface to properly integrate a modern phone with Toyota/Lexus infotainment systems from before 2010 (which are using the proprietary AVC-LAN protocol).

I've explored all existing commercially available solutions and none match my requirements/standards (high-quality audio codec/DAC, USB-PD, steering wheel controls, no splicing or cutting into the loom, no cutting up the dash, etc.).

After researching how the Toyota/Lexus infotainment systems work I found they are highly modular, and actually quite easy to produce custom modules for. The proprietary AVC-LAN protocol is well-understood, and actually makes it really easy to integrate with. The display are just NTSC composite, and touch events (in fact, all button presses, including steering wheel media controls) are emitted on the AVC-LAN bus.

An simple board with some interfacing logic, a DAC and an RPi nano should be all I need to allow good Bluetooth audio integration, and lossless audio via wired USB, both controllable from the steering wheel. You could do all sorts of fun things with the display (such as displaying vehicle status from ODB, lap timer, G-force meter etc.). If I use a RPi compute module then running Android Auto should be quite feasible.

It's just a hobby project though, I'll probably open-source everything. Not planning on commercializing it.

MrG3D4• 1 year ago

Version 2 is being built around a CM4 IO board and will include my AVCLAN implementation, DAC, GPS and is intended to run AOSP Android. The board is fully designed already and I'm working on the custom Android build now.

LeonM3• 1 year ago

That's really cool! Looks like you found the same resources as I did on the AVC-LAN inner workings.

It's also fun to see how each Toyota product uses the same modules and buttons, just different layouts and front panel designs. Your solution (sans the custom display that will only fit your model) should work on just about every Toyota and Lexus model from the AVC-LAN era (2000~2010)

Not sure if you'd be willing to share your code or diagrams, but anything would help me tremendously. My contact info is in my bio.

loufe3• 1 year ago

Godspeed. I find it frustrating these systems don't follow some sort of international standard, still. I can't justify replacing the system in my 2016 Highlander just to get Android auto, but the Bluetooth system handles non-phone calls poorly and the album art database hasn't been updated for basically the entire life of the vehicle. I don't like having to rely on the manufacturer nor Google/Apple for connectivity basics.

LeonM3• 1 year ago

I find it frustrating these systems don't follow some sort of international standard

They do, actually!

Most car manufacturers, including Toyota, now use the MOST-bus for infotainment system interconnects, which is an open standard. So your car being a >2010 Toyota, it will have a MOST system.

I can't justify replacing the system in my 2016 Highlander just to get Android auto

You don't have to, there are plenty of aftermarket modules available that will add Android Auto to your existing MOST infotainment system. Can be a hit-or-miss though in terms of quality and integration. If you want something reliable and well integrated, stick with the OEM solutions.

I don't like having to rely on the manufacturer nor Google/Apple for connectivity basics.

You're already relying on the car OEM for mobility and your safety, and you're already relying on Google or Apply for connectivity (aka: your phone's OS).

Remember that your 2016 Highlander (3rd gen XU50) was introduced in 2013, so developed well before that. Android auto didn't even exist back then, and we still hadn't consolidated on the iOS/Android duopoly we have today. Heck we were still using Windows phone and Blackberry OS back then. How could Toyota engineers have designed something that would still remain compatible with devices in 2025? Quite remarkable actually that it still works at all.

thoughtpeddler• 1 year ago

This is awesome! I suspect I have vasomotor rhinitis and could use something like this to track the same sort of sinusitis-type symptoms. My nose basically hasn't stopped being wet and runny for the last 20 years. Two questions: (1) Where is data stored? (2) Are you comfortable sharing an open repo on GitHub?

linsomniac2• 1 year ago

The data is stored entirely in your browser. Meaning, be careful about using an incognito browser window. I probably should have it add a "download data" button combined with "upload". I should also add an "About" with information about this and also a pointer to the SNOT-22 sources.

My situation is I possibly have a "local rhinitis", though my ENT dismissed that. I base that on him visually confirming that I have an allergic reaction in my sinuses, but my allergy screening on my shoulder showed no reactions. But it might also be a lot of other things including being in an extremely dry environment. Next steps are to get a CPAP, which will give me high humidity air and treat minor apnea, and a nebulizer treatment once a quarter, plus taking allergy medicine semi-regularly.

ATM, I'm not planning on releasing the source. Due largely to being way, way underwater on time available to deal with my existing projects. Is there something you wanted from the source? If you are interested in auditing it for where the data is stored, try using your browsers developer tools and watch the network traffic while using it.

Last year I bought a broken jukebox. I wanted to convert it to be powered by a raspberry pi. I wanted it to work like a traditional jukebox where you used the buttons to input the song number. While there are a few existing projects to convert Jukeboxes to run from raspberry pi, most of them used a touch screen or didn't work well on RP5 which is what I had or the current version of raspberry pi os.

So despite not being a programmer, barely knowing a little javascript, and nothing about python, linux, or gtk, I was able to use AI to muddle my way through to creating a program that takes the input from a numpad, looks up the song from a list, sends it to mpd, and posts a picture from the album art embedded in the music file. https://github.com/jccalhoun/mpcButtonJukebox

At home... about to welcome a dog, so that's going to shrink my free time even further.

On the "side projects" side of things, I've been working on a "boot to EndBASIC" disk image since December with the goal of creating a small "dev kit" box that boots quickly and directly into the interpreter. The disk image is pretty much done for a first release, so now I need to get to the design and 3D-printing of a case for the board+screen combo. The latter is brand new territory for me, and I have a self-imposed deadline of June when I'll be presenting this at BSDCan.

... but I've also taken a small detour to improve the EndBASIC website and provide a dynamically-generated gallery of user-uploaded projects. This has been a deficiency for a while and I felt it'd be easy to add it, right on time for the "dev kit" release.

Stay tuned!

Building an app that extracts key information from PDFs + highlights citations.

You provide a PDF and a JSON schema defining what to extract, and it returns the extracted values, the citations and their precise locations in the document.

This is especially valuable in workflows where verification of LLM extracted information is critical (e.g. legal and finance). It can handle complex layouts like multiple columns, tables and also scanned documents.

Planning to offer this both as an API and a self-hosted option for organizations with strict data privacy requirements.

stego-tech• 1 year ago

I'm in the midst of a tectonic career shift, from being laid off from a position and place I loved, to another gig while I keep looking for another unicorn role like before.

So most of my project work is home-based, after years of being able to chase (and execute) dreams at work.

On the technology front, I'm finally investing in a proper network core for home. WiFi 7 AP, 2.5Gig core, PoE everywhere, zone-based firewall. Still mapping out DHCP scopes and VLANs, but once that's done it'll be moving on to proper IoT and Home Assistant build-outs to prepare for the Unfolded Circle 3 later this summer. Also looking to redo my two N100 hypervisors off Proxmox and back to RHEL + Cockpit, or some other Linux + KVM implementation; from there, it's all about Kubernetes, Ansible, and Terraform. Really just a lot of oft-postponed side projects because I had amazing fulfillment at work, that I suddenly have ample time for now.

Outside of the tech stuff, I'm still trying to get some decent photos of two local birds of prey that have been hunting in my neighborhood. They seemingly spite me by only showing themselves when I don't have my camera with me, but dangit, I will photograph them.

On the writing front, I've got a few topics jostling around in drafts: speculating on potential futures of LLMs, the internet as a psychohazard, and a series of "fundamentals" to try and teach my non-techie circles more about how computers and the internet work, so they can do some modest self-hosting and get off centralized services. I'll likely dovetail some of them with my own home projects, writing them alongside the documentation as I make progress.

I find tracking movies and series I have watched with my partner an impossible task. Spreadsheets are too fiddly for my partner, and I want to look up what is next on my phone so I have turned to Airtable and n8n for automation.

input a relevant url, it will decide if it IMDB or Youtube or a list. using an llm, it will attempt to extract the movies or series from the list and find the relevant IMDB link.

Then I have a masonry view of movies & series I have and have not watched, sortable by tags that I can rate and add notes to.

cmdrk2• 1 year ago

I'm still tinkering on my multiplayer game server framework when not grinding away at my day job.

The idea is essentially: An Erlang-based control plane, supporting ENet and WebSocket connection modes, with Protobuf for messages. Erlang has an excellent concurrency story, and I think it's a great fit for game servers. I've wrapped up a bunch of this work into behaviors on the Erlang side, such that developers can target the "gen_zone" behavior (for instance) to implement a tick-based game server. I'd like to expand that into other types of games, such as turn-based games.

I've also got a Godot plugin for generating a client library based on your protobuf schema. The plugin handles session stuff, exposes functions for client-to-server messages, and emits signals for server-to-client messages.

These days I'm working on integrating Luerl (Lua in Erlang) and Love2D support. I want to be able to take advantage of Erlang on the back-end while writing the majority of game logic in Lua. Further down the road I want to explore hot reloading parts of the Lua game state on the client/server, perhaps with an in-game editor, to develop the game "inside-out", in a way.

to-too-two4• 1 year ago

Sounds cool. I'm interested in netcode using Godot. Is there a Git repo I can check out?

cmdrk2• 1 year ago

Godot has a nice netcode story with ENet, WebSocket and WebRTC integration. If you just want a off-the-shelf product instead of bespoke Erlangy stuff, I think there are a lot of good options out there like Godot's native high-level networking, products like Nakama, etc.

Working on Taskade (https://www.taskade.com), building the execution layer for AI collaboration.

Taskade started as a real-time workspace for teams to organize projects and ideas. It's evolved into something bigger — a platform where humans and AI work side by side.

We’re moving past simple chatbots into real agentic workflows, where teams can generate structured task lists, mind maps, and tables, train custom AI agents with dynamic knowledge, and automate work from start to finish.

Today, Taskade is built around three core pillars: Projects, Agents, and Automation. It’s like giving your team a second brain that can think, plan, and get work done across projects, automations, and real-time collaboration. If you’re interested in the future of human-AI collaboration, take a look!

I've just tried other windows managers on windows and felt that have either been slow or buggy and wanted something that looks nice. My inspiration is based on Hyperland, as im currently dual booting and when I work on windows, all i want is a nice window manager.

still very early in development but im excited for its potential.

This also goes in line with my current studying of the windows OS, so its a bit of learning and then working. :)

Just a small hardware project: I am building a cocktail mixer in an old PC case. I saw something similar at a con over Easter and had to build one myself, it had a tap coming out of the 3.5" bay and the ingredients were inside the pc case. It uses peristaltic pumps to move the different ingredients to the cup. It is very simple, but still took a couple of days to complete. In detail it consists of 6 x peristaltic pumps, 3 x L298N motor driver, 3 x PCF8574 io expander and an esp32. The software for the esp32 is very dumb and I actually coded it correctly before I had all the parts, it just enables and sets the speed for the motors and is attached via USB to a laptop. There a webapp is used to manage ingredients and recipes.

My project is an ongoing one of self improvement. I've spent most of my adult life working on technical stuff, and it's taken a bit of a toll on me.

I quit working about ~20 months ago, started a low-carb time restricted eating regime, lost ~230 lbs, have been doing 15-25 hours of cardio a month for the past year, started going to therapy, got an ADHD diagnosis, read a bunch of classic literature (Middlemarch and The Count of Monte Cristo are my favs thus far), maintaining a 19 week streak of Latin language learning through the killer Legentibus iOS app, and I'm playing guitar every day (trying to nail the the major scale in three different fingerings across all 7 modal starting points).

I miss my old job working with Vitess and Kubernetes a lot (Hi Sam!) but eliminating all work stress has really allowed me to take control of my life.

Having enjoyable text to read/listen to that is just comprehensible enough to get you to keep working at it really a pleasurable way to learn a language. LLPSI is also great, and at times is a delightful read. I find myself also really enjoying Ørberg's student manual, in which he reveals (in English) all the finer points of the Grammar the text is trying to get you to internalize. It's amazing how much grammar you can just intuit by reading -- like I understood participles without explicitly realizing they had been introduced in Chapter 14.

230lbs is wild. Great job :)

gtowey• 1 year ago

Diet matters. Protein, especially in the morning. Carbs and sugar are so bad for focus.

Sleep is essential. Getting a full night of quality sleep will probably help more than anything else. If you often wake up feeling tired already then maybe do a sleep study to see if there are problems there.

Exercise helps.

Developing a system for organization is key to unburdening your mind. There are various books for adults, for me I also found an executive function coach gave me the right amount of accountability and discipline to practice the systems enough that they didnt feel like a burden anymore.

spudlyo3• 1 year ago

Thanks! It has helped explain a lot of things about my life, and what I now understand as dopamine-seeking behavior, as well as why I found it so difficult to switch focus once I became obsessed with something.

I got a prescription for Adderall, and I take 10mg dose a couple of times a week when I need to get psyched up for deep-cleaning the house or doing a week's worth of food prep, or folding and putting away a mountain of laundry. Moving your body doing repetitive manual tasks just feels amazing on speed. My wife is pretty happy not having to over-function for me, and to have help around the house. Having healthy food that you want to eat in your fridge is also very helpful.

I seem to get plenty of motivation and focus for doing things I want to do by doing an hour of cardio every morning at the gym. Recently I've been moving between HR zones 1-4 while listening to the 4 movements of Beethoven's 9th, which I have a recording of that is just over an hour. I sometimes time it so I walk out of the gym at the end of the 4th movement to thunderous applause in my headphones. Reading while doing boring steady state Zone-2 on the elliptical is amazing -- I rarely feel smarter or more engaged. I read all of Jane Austen's novels that way, and it inspired me to read more!

I also go to bed every night at the same time, get up at the same time every morning, and if I don't manage to get at least 7 hours of sleep I take a nap during the day. I have developed friendships with the regulars at my local coffee shop and often have good conversations at nearly the same time several times a week. I meet with a couple of old college friends every week for dinner. I also take leisurely cold-ass showers every morning when I get back from the gym to prove to myself that I have executive function, and because by the time I've shaved and brushed & flossed I feel like a million bucks.

A series of pulpy short stories, sort of a Dark Americana / weird fiction thing. Noir, magic, existential dread, horror. Warming up for a novel in a completely different genre but I wanted to iron out some of my own shortcomings and stretch some muscles before I write yet another 100k words on a project I'm unhappy with.

spoonsort• 1 year ago

That's right up my alley. I've been thinking about writing something in this style but with a jazz biome twist (kind of like steampunk but with a jazz-centric world instead of steam power). Do you use a specific text editor or git workflow to manage your work?

Tallain3• 1 year ago

That also sounds super fun. I love it when things get hyper-specific like that. If you ever need a beta reader, let me know.

I use a mix of things. For a long time I used vim with some plugins to emulate iA Writer, along with vimwiki for general notes. Now I use Obsidian for notes (general stuff like character bios, tags, ways to track relationships, worldbuilding stuff).

I use iA Writer for a quick outline and first draft because it's simple and distraction-free, and I like its focus mode. Again this can be done with vim, I can send you my .vimrc if you're curious. I just wanted to support the company.

Once the first draft is done, I spin up Scrivener. I put in the notes from the outline into the corkboard view, then paste the draft. I read through it front to back and take notes, usually in iA where the outline was. Then I create a new version of each doc, one by one, and do line edits or rewrites where I see fit. Sometimes I rewrite something wholesale, or split it into multiple scenes, or delete completely.

Scrivener is very handy for this type of work, especially with the corkboard view, which lets you slide things around and see a story from a higher level than headlines or chapter / scene titles would.

I know Scrivener has a focus mode, but I use iA specifically to remove distractions. If I have Scrivener open, I'm tempted to fiddle with things in its UI, or try to take that high-level view too early. iA is for drafting because drafting is supposed to be a single-minded enterprise. There's no room for second thoughts and any loss of momentum kills a story for me.

I'm developing PAPER (the Python Application, Package and Environment wRangler, a Python package installer), and will soon return to bbbb (the Bare-Bones Build Backend, a build backend for Python packages).

PAPER is designed from the ground up to avoid Pip design mistakes, directly taking advantage of new standards while also offering Pipx-like functionality. Unlike uv, Poetry etc., PAPER is not a project manager or workflow tool; it installs the packages that you tell it to (and their dependencies), when/where/because you do. It's entirely user-focused, and usefulness for developers is treated as mostly incidental. (However, it can of course form a useful part of a proper development toolchain.)

It's not in a publicly-usable state yet, but these are the main design principles I'm working from:

* It's designed from the ground up to provide a programmatic API and to install cross-environment (in fact, you're only expected to install in its own environment in order to provide plugins). The API is provided by a separate wheel; other projects can explicitly cite that as a dependency and don't have to `subprocess.call` to a CLI.

* Size and performance are paramount. (Much of Pip's slow performance on smaller tasks is due to its size). I'm aiming for ~1MB total disk footprint for the base installation (compare ~10-15 for Pip, which is often multiplied across several environments; ~35 for uv). Dependencies are very carefully considered; installations are cached as much as possible (and hard-linked when possible, like with uv); etc.

* The program bootstraps itself as a zipapp that pre-loads the program's own cache before having it install itself from its own wheel (within that cache). This entails that there aren't any "hidden" vendored dependencies; anything that ends up bundled with PAPER can immediately be installed with PAPER, without an Internet connection.

* Non-essential functionality can be provided later by simply installing optional dependencies. The default is sufficient for the program to install wheels with minimal feedback.

* The CLI is built around separate hyphenated commands rather than sub-commands, for simpler implementation and better tab-completion. Commands are aimed at offering somewhat finer-grained control while keeping simple use cases simple.

bbbb is largely inspired by Flit, but is also intended to support projects with non-Python code, and doesn't enforce distributions with a single top-level import package. It uses the same split between a core package and a full development package, except the core package is treated as default. It's designed to be even more minimal than flit-core, and in fact can only build wheels by itself (dynamically pulling in the dev package if asked to make an sdist).

The goal is to minimize download footprint and maximize modularity when end users download an sdist and want to make a wheel from it (for example, implicitly via an installer). Users will declare the dev package as the build system in pyproject.toml, and may even declare it as an in-tree backend which will then be automatically added to the sdist. So people who (for some reason - perhaps to satisfy Linux distro maintainers) want to distribute an sdist for pure Python code, won't need any build-time dependencies at all.

Building non-Python code in bbbb, as well as customizing sdist contents and metadata (beyond what's directly supported), works by hooking into arbitrary Python code. Unlike the setup.py of Setuptools, the code can have custom name and locations specified in pyproject.toml, and it has specific and narrow purpose. I.e.: it's not part of implementing a class framework to power a now-deprecated custom CLI; it only implements compilation/metadata creation/manifest filtering - and does so with a much simpler, more direct API. You're meant to build upon this with additional support libraries (e.g. to locate compilers on the user's system) - again, modularity is key - that are separately listed as build-time dependencies.

I'm trying to make simple, elegant, pure-Python tools that complement each other and respect (my understanding of) modern Python packaging standards and their underlying goals. A developer could end up with a toolchain that looks like: PAPER, bbbb, build (the reference build frontend provided by PyPA), cookiecutter (or similar - for setting up new projects), twine (the default uploader), and some shell scripts - for things like "install dependencies with PAPER in a new environment and then add a .pth file for the current project to that environment". (And if you like linters and typecheckers, I certainly won't stop you from using them.)

I'm working on my second self-published technical book related to Elixir. The first one has been a surprising success, but since it was about learning to use Ecto on the basis of an old pedagogical toy database (and tiny dataset), the new book is about the development of a production-grade REST API with Elixir and Phoenix.

I find that many books out there are focused on documenting the "happy path" for rather small and simplistic applications without boundary conditions or business thinking behind them.

So, I thought (as with the first books) that it mix things up by also documenting the business context, the questions, decisions, and the decision-making process itself, as well as all the gotchas and "side-quests", rather than showing "here's how you do it" and then expecting the reader to suddenly make the jump from tutorial hell to actually software engineering.

Overall, it's enormously enjoyable, and I hope it goes as far as the first book, and possibly even farther.

I recently published this library for routing messages within an application using the same kind of wildcard semantics that NATS uses - https://www.npmjs.com/package/@gooseus/natsrun

Currently just test driving it in some relatively simple work scenarios, but I imagine it could be a useful tool for consuming a NATS firehose of messages in a single application and routing them internally using the same semantics subject rules so that it would be easy to split them out as separate consumers when/if that became necessary.

I work at a small startup trying to hire engineers and got tired of looking through resumes. As Joel Spolsky points out, they're not great indications of technical ability. Instead, I decided to throw together a take-home challenge that applicants could access via an API. "If they can't solve the challenge, I don't need to see their resume," I told myself.

FizzBuzz.md is a better version of the solution I built for work. It lets applicants send questions and submissions to configurable email addresses via API so the email addresses aren't exposed directly. (Less spam, FTW)

There is still a lot to do and learn (especially in the marketing department), but we have plans for a new product in the privacy space. I don't want to say too much about it until we've started working on it, but it's in the compliance space and fits quite well with our existing product. I think it's always a good starting point to solve your own problems.

Cloudflare gives us the ability to offer developers compute, database, storage, queues, AI, realtime with durable objects, etc... and to emulate that locally with just a single package installation.

I'm hacking on Trailbound, a hiking and backpacking planning tool. The goal is combining a light version of the routing capability of Caltopo or GaiaGPS with more granular "leg" mapping based on how I learned to plan off trail trips and sharing functions that make it easy for my wife to know where I'm going to be, who I'm with, and who to contact if I'm not back in touch when I said I would be.

Its been a blast to build. At one point I was hosting my own ORS server but that's extremely silly to do when Mapbox has a very generous free tier. Learning about all of the open source tooling and open data available in the mapping world has been incredible.

The cost of the Hetzner box it runs on isn't much more than a Caltopo pro subscription with the added bonus of being much easier to share with non-hikers.

A quick demo: https://www.loom.com/share/a5f7a7c23457400aa92b3f0f71a0008f

The app: https://go.trailboundapp.com

No marketing site, no onboarding, or any real UX attention paid to the app at this point, it is mostly Just For Me and will probably remain that way once I land a job again.

https://github.com/runsecret/rsec

An easier and more secure way to work with secrets during local development. It’s open source, cloud/vault agnostic, and doesn’t require a single line of code change to use. I call it RunSecret.

RunSecret is a CLI that replaces your static secrets with “secret references” in your ENV VARs (or .env files). These references are then replaced when your application starts up by reaching out to your secret vault of choice - making your .env safe to share across your whole team and removing a slew of gotchas when you use git ignored env files. Even better RunSecret redacts any instance of these secrets from your application output, reducing your chances for accidental leaks.

The approach is inspired by the 1password CLI, but built for the rest of us. I’ve got AWS Secrets Manager support pretty well baked, but the goal is to support all major secret vaults within the next couple of months (Azure KeyVault is already in progress).

firesteelrain6• 1 year ago

Interesting approach. Why this over GitLab secrets that are integrated with a vault of choice?

I assume this is to cover the non-CI/CD scenario.

devenjarvis4• 1 year ago

Thanks for checking it out! The pain point for me has largely been during local development, especially in a team setting when secrets change or people onboard or roll off and those manually managed .env files get unwieldy.

Gitlab Secrets looks cool, but that hits at another reason I think RunSecret is valuable even for CI - we don’t use GitLab at my day job so it’s not an option for me! I think GitLab and 1password have interesting proprietary solutions that definitely have inspired RunSecret, but I’d love to see an open source, universal solution here - which I’m hoping RunSecret can be!

I really like the idea of contributing those photos back to OpenStreetMap actually... right now I have Google Maps on profile pages but only because we absolutely need the Google Places API for accurate hours (that's really the only spot businesses update current hours at the moment).

I'm working on a little 2D action puzzle game in Go on top of SDL (with bindings via https://github.com/veandco/go-sdl2). The prompt I've given myself is "Chip's Challenge meets Hotline Miami," but who knows how much of either of those elements will remain after I keep evolving the capabilities and general feel of the gameplay. For dev graphics I'm just cobbling together sprites from various pixel-arty asset packs I've purchased on itch.io, but in the future if I want to commercialize it I'll probably want to work with an artist to develop a unified look-and-feel for the game--I may even switch to 3D/2.5D depending on how the tone and my workflow evolve.

I've experimented with Unity, Godot, and GameMaker in the past, but for the time being I'd like to see what I can accomplish on my own in Go to keep my dev chops sharp especially since I've moved into an engineering management role at my job (which has nothing to do with game dev but is increasingly employing more Go source throughout). Something I've realized as I've been applying good code organization and reusability is that I'm essentially building an engine for anything top-down (hesitant to say "isometric" since I know that means something graphically specific)--RTS/TBS/tactics/RPG all seem doable with what I've built given a little bit of extra logic on top for each.

I recently started learning Rust so for my first non-trivial project I decided to build a system for real-time generative art driven by a DSL (defined with Pest) and interpreter that executes scripts for creating dynamic and interactive visuals. The goal is to make human-authored, interactive art more accessible than current methods like GLSL/ShaderToy but without going down the path of AI-generated content, although in theory there's nothing preventing users for using AI to generate scripts for this system. The project uses Nannou for graphics (via WebGL) and input handling (keyboard, mouse, MIDI, audio analysis). It will target WASM and I'll make it accessible as a web app where users can create and share their own projects. I'm also exploring community features to support collaboration and discovery. Still early days, but it’s been a fun way to get deep into Rust by building something creative and open-ended.

Basically a test of putting guard rails around format and content of a website and seeing how much I could automatically generate on a topic of interest to myself.

Biggest benefit I've seen with cursor is to write tests for everything. Far too mcuh content hallucination, or made up links at first, but once you put in some test guardrails you can minimise this.

I am building a service to make accessing AI as easy as sending email called ThreadWise

https://threadwise.app

You can email prompts directly to your ThreadWise address and get instant AI-powered responses, essentially an always available co-worker. Another great feature is the ability to schedule recurring tasks and since the AI has web access, you can get things like:

Daily mortgage rates or airfare price monitoring

Weather and news summaries

Sport scores, jokes, quote of the day

Pull data from public APIs (and more)

So you can essentially use it as a personal newsletter, crafted to your taste.

The free tier will let you test this out for free! I am looking for some feedback/criticism, testing, and additional ideas and I am open for collaboration if you have experience with sales. Also open to hearing which scheduled tasks people would find most useful.

Why I built it: I noticed a trend online, as well as with family/friends, that people would like to have a quick access to AI in instances where they couldn't always install apps or use browser-based tools (such as in remote/low bandwidth environments). This is when it him me, email clients already have all the features needed to interact with an AI (text + attachments) and I quickly got to work.

Some of the advantages are also that since there are no new apps, or browser tabs needed, the tool is ideal for companies who don't have the bandwidth to setup full fledged AI solutions on their own. The companies can choose either between public LLMs (e.g. OpenAI) or host everything on-premise with locally run models, so no data ever leaves the premises.

Eager to hear what you all think!

What’s your method?

Having had some former coworkers that ended up at various dating platforms, dating is fascinating, I still think dating is something that needs a better modern solution than what “the apps” offer. Every dating app has a few fundamental flaws. There’s the human element too.

What worked for me was hacking Tinder circa 2014 by faking my geolocation and hypertargeting certain places and neighborhoods I knew would be up my dating alley and spamming posts on social media sites like Reddit and Craigslist.

It’s tough because some people don’t even know what they’re looking for in a partner.

Recently I’ve pretty much replaced searching Yelp or TripAdvisor with a combination of Instagram Reels/TikToks and Google maps for travel and food recommendations. I usually just save a lot of places that I have to dig through and watch again to dig through and add to my saved Google maps lists. Because this takes me a fair bit of time when preparing for a trip, I decided to automate part of it by building a pipeline to “watch” the video for me by getting the audio and video frame data and taking into account key POIs that I then export out to a note. Later I plan to also integrate this with other travel or food tracking software like Wanderlog, Google maps list, or Beli eats. So far it’s been working well, but def expensive (so thank god for free GCP credits haha)

I'm working on a universal tool to create and print custom dust jackets.

I like collecting books and have lots of series, but editions and cover/spine designs changes all the time for no good reason. Especially for long series it's near-impossible to get a collection with consistent styles, which I find frustrating. And when buying rare or old second-hand books online, it's even worse.

The app will allow you to enter your book information (title, author, size, summary...), then choose the design/layout. You will then have the option to print it by yourself (for free - if you can find a big enough printer) or get it printed by a professional.

For awhile I've been working on an MPE MIDI controller called the Mosaichord. It uses a tuning system called just intonation, where the frequencies of all the notes are related to each other by whole number ratios. I'm using a scale that has 28 notes per octave. Keys are pressure sensitive.

A few weeks ago I got a video of one of my friends playing it at a show: https://mastodon.social/@DesiderataSystems

Something I'm working on right now is trying to implement a basic on-board synthesizer so people can use it without a laptop or external hardware synth. (I added a DAC a couple hardware revisions back, I just haven't done anything interesting with it yet.)

This is a complete remake of the original I made a long time ago for the Mac App Store, sharing only the name. I realized it was better to use the jq language since it was already familiar to many people and way more powerful than designing my own query language. I also do not agree with Apple's App Store command and control so I've decided to make it a web app, and I'm astounded at how much more powerful web apps and their DX are compared to native application development in the Apple world.

It's niche and boring, but I help immigrants pick German health insurance.

The existing information is mostly blogspam from non-experts who try to make a quick buck. They only recommend the two brands with an affiliate program.

I wrote a better guide with help from competing insurance experts. The information is clear and succinct without oversimplifying things. It addresses the specific needs of immigrants.

Then I turned the advice into an interactive recommendation tool. People get clear, specific advice in a few seconds.

The best advice is "don't choose yourself, talk to a broker". The problem is finding a honest one. It took me years to vet a good one. After testing him for a year, I have set up an affiliate partnership from scratch with him. The partnership incentivises honesty and neutrality, because he has a lot of skin in the game.

I'm super excited about it. I can't overstate how much of an improvement it will be. Readers get far better advice and easy access to an expert. The broker gets a steady stream of well-informed leads. I get a commission for my trouble. It's a win-win-win situation.

My plan for the next step is to detect faces, ask the user to label the most occurring faces, and then label all images accordingly. This step seems a bit harder than just feeding the image through Gemini and asking it to create labels.

I've recently re-watched John Carmack's 2004 Quakecon keynote (https://www.youtube.com/watch?time_continue=602&v=OOVUZZr655...), which happened during the Doom 3 launch. In that keynote, he mentions that he didn't see any differences between stencil and shadow maps. He mentions that he experimented a lot with both approaches, before settling for stencil shadows which were much faster.

I got curious about that statement, since shadow maps tend to look much different. I also knew that he left part of the experimental renderer in the GPLed code. So, I've decided to go on that rabbit hole of Doom 3 graphics, specifically Carmack's experimental renderer and ended up implementing his approach, as well as adding some poisson disc sampling and fixed the peter panning: https://github.com/klaussilveira/exp-dhewm3

I also spend a lot of time on archaic game engines. I like to call it software archeology.

It’s not much, but it’s all I can cram into the free time I have, there’s a possibility I might actually finish it for once, and it’s something I could actually use once it’s done.

A tool to organize my life.

All the things that are important to me in one place: notes, habit tracker, brag doc, action log, todos, events, data collection, biolinks, and a lot more.

That certainly sounds a bit boring, and rightly reminds of great tools like Obsidian. However, there was always something missing from the tools, or the configuration was too complex. That's why I started to build one myself. It's a mix of pwa and local-first and Github sync. I don't want a tool that only works in the browser, I also need to be able to continue working seamlessly on my smartphone, and Github offers an endless history that I can view. Plus: I can clone the repo locally at any time.

I don't need a habit tracker service, a tool for notes or a brag doc service anymore. Everything is stored as files that I can access at any time. Other nice features are forms (like typeform) or an infinite number of biolinks.

I've been using it daily for a few months now and have already been able to replace a few services with it.

I'm almost finished with a project that has taken up quite a lot of my life for the past few years, a book on Estonia! After working for their government and returning to the U.S. I wanted to better understand how the country modernized so effectively after gaining their independence from the Soviet Union so I did a fair amount of research into the topic and many interviews which culminated in a book, Rebooting a Nation.

If you're interested in Estonia, e-government, building tech hubs, and the future of the nation state I'd love if you take a look (and let me know what you think). It's available on Kindle now but Oxford University Press will be shipping out physical copies May 15 and buying from a smaller press is always appreciated!

After sure global success of this book, would you consider having another go about similar topic - this time about Poland? (my country)

It might be interesting to see similar area from similar, but different enough, perspectives.

atlasunshrugged3• 1 year ago

I appreciate that! Honestly, I'm not sure. Part of the reason I felt competent enough to write about Estonia is because I had lived there and worked for the government, so I thought I had a pretty decent insider look into how things worked and could tell the story well and I'm not sure I could replicate that in Poland. Although I do think a comparative study across some digital leaders (ex. Estonia, Poland, Ukraine) or even just comparing the Baltic states on topics like digitalization would be super interesting.

MindJam helps brands, studios and creators understand their YouTube communities.

MindJam analyses millions of YouTube comments to instantly reveal the unfiltered voice of your audience – their true sentiment, emerging themes, and the topics they really care about.

Here is a sample analysis - https://mind-jam.co.uk/analysis/HPMh3AO4Gm0?utm_source=hacke...

I didn't intend on building MindJam... I wanted to learn about LLMs.

At first I wanted to see how Laravel would/could work with an LLM and after doing some reading I ended up learning about OpenAPI 3.0 Schema and Multi-Modal RAG.

In the last few months I have built on top of Gemini, Claude and OpenAI. All have their perks and quirks.

I am hoping this learning is only the start of a pretty cool journey.

shkurski_• 1 year ago

https://shkur.ski/notai A tool that automatically shows you relevant information as you work so you don't have to search for things manually. With privacy guarantees.

Being sick of where things are headed, I didn't want to join the "trend". Instead, there is NotAI. I built it for myself first and foremost, as I am:

  1. Too lazy to Alt+Tab into Notion in order to write a note or find it. Instead, I want to select text and write a note in-place. Next time when I see something relevant on screen, I want it to appear.

  2. Usually distracted with the need to structure information manually. If you see it on screen, it should be enough. With NotAI you see a name in messenger -- it adds contact automatically. You see meeting caps -- it memorises them. Etc.

  3. Tired of bloatware, all those 500MB text editors draining the battery. I wanted it to be fast, small and smooth. NotAI is fully native, consumes a few tens of MBs and runs even on modest 5-7 y.o. laptops. It's fully local, meaning no network requests / server-side processing -> reaction time is usually within 40ms.

  4. Sick of marketing bs. Privacy-first products with telemetry and requests to ChatGPT. Attempts to achieve "privacy" by redefining the meaning of it. I no longer believe what I read. If it's private, I want guarantees! So NotAI is fully local. It's a single executable program. You go Windows Defender (or any other firewall) and block it from network. Period.

Here is an old tech demo from last year: https://shkur.ski/notai/demo.mp4

Debugging co-routines / threading is a pain in any language. I'm a big believer in observability anyway so this isn't a leap. Nor is it the first time I did this very thing, but last time I had implemented a console and it was a console command. This is in a product written in Python which implements a DNS gateway for Redis:

    # dig @sophia.m3047 coroutines.redis.sophia.m3047 txt +short
    "write_control:1"
    "get:3"
    "statistics_report:1"
    "process_pending_queue:1"

The implementing code (not including turning it into a DNS response) is surprisingly simple: https://github.com/m3047/rkvdns/blob/f6fba9523a83aa5125378bb...

I'm about to wrap up the alpha release of an Rust/Tauri based GUI desktop app that allows me (and others if interested) build modular AI agents. At this point it gives you control over the system prompt, LLM, message and which MCP tooling you want to use (to prevent cluttering the request with 69 unnecessary tools you do not need anyway). You can store agents as templates, so you can reuse them with ease.

pile - a framework & cli for managing a large number of docker-compose files running on the same machine.

Inspired by a pile-of-poo SOA application where essentially every service was dependent other services such that the entire app stack needed to be run in order for any 1 service to work.

In addition to organizing the array of docker-compose files, which may live in different directories, i also add some helper functions to bring clarity to the usual docker cli output. Ugly "docker ps" output can be gathered by using pile ports, pile commands, & pile state - all of which output what you think they do, but in a way that is actually legible and useful when running 20+ containers locally.

I've been building an intentionally annoying app against doomscrolling [1]. I've recently started with marketing, but oh boy is that out of my comfort zone!

I never thought that as an engineer I'd be doing TikToks. And here I am. It's fun to crack the algorithm little by little, but also frustrating because it's like a black box.

So far, I've discovered that going to the point works best. For example, I was sharing student tips and mentioning my app to improve focus. But conversion and engagement were terrible. Instead, I'm doing founder stories and tutorials, which get less views but more downloads. Plus, I can ask people in the comments for feedback on the app!

I'm happy to be doing something that devs overlook so much: marketing. Even if it's tough and slow. It's been an awesome learning experience.

Currently working on a USB/Bluetooth to Sega Dreamcast controller adapter.

It's based on the Raspberry Pi Pico 2/W board and originally started as a fun project to play around with the PIO features of the RP chips and get my Steam Controller working on the Dreamcast. It has since expanded to support more controllers, keyboards, mice, and acts as VMU - the Dreamcast's memory card - while plugged in. Building the dongle itself has also been a fun exercise in 3d printing, cad and pcb design.

I'd really like to expand the amount of supported USB devices as I only have access to a limited amount of hardware that I can test myself. I've started looking into if I can use the SDL Game Controller DB (https://github.com/mdqinc/SDL_GameControllerDB) to kind of crowd source support for a bunch of controllers. I'm definitely open to other ideas though. I feel like I'm slowly learning that USB controllers are minefield of one-offs and edge cases.

It's a pretty specific niche with interesting challenges like massively varying project sizes (ranging from a few pages to 20,000+ documents), a high importance of graphs / charts, and very different extraction tasks (from more qualitative analysis to quantitative, exhaustive lists which is still a pain point).

Built most of the pipeline by hand, mostly because I started this earlier than many RAG tools came out, but I am glad I did because we needed a bunch of adjustments and changes that might have been hard with something ready-made.

An IDE for agents, that includes a general purpose agent inside so developers don't need to start with a framework or from scratch. It just works, out of the box.

I feel that the software development lifecycle for agents is uniquely iterative and requires a different set of tools and environment, so that's how this came to be. First we built the general purpose agent -> now we build the IDE around it.

Hi all! my name is Patrick and I'm a linux platform engineer out of Waterloo Can. This ( https://imgur.com/a/14YMyVN ) is a collection of Nesticles - lightweight isolated immutable desktop system containers using modern linux compositor technologies and shown on a debian stable host platform and targeting PC grade hardware. These are getting very useful and present opportunities to theme and deeply customize for your personal use or for an organization or company. On average they consume like 600mb of memory per running container, so you will see ~30 envs running there comforably in those screenies. Nesticles is also a platform for unifying desktop and app delivery, providing some building blocks for composing up useful containers. Currently these environments are specified as docker-compose projects, including all of the apps. Could anyone see these becoming useful to you? It kind of scratched a 20 yr itch I'd had since being a young lad configuring desktops painted on cubes and such. I'm shooting for initial support for the following host platforms (debian, ubuntu, steamos, windows, mac). I'd like to bring a launcher to Steam to fund dev and bring the core definitions to the community perhaps as open-source container definitions. Any suggestions or thoughts on Nesticles or lightweight desktop containers? I do view these as building blocks in some larger or more specialized system, but they have utility for desktop use cases now. Ps. I'm also currently on the job market if you are looking for a platform/backend developer - please see https://paddymahoney.github.io . Thanks all, Patrick.

Working on specstory.com which today is an extension for Cursor & Github copilot that allows you to save, search, share your AI chat history.

Most AI first coding tools don't seem to respect how much critical context gets lost between sessions. Prompts, chats, refactors, decision paths all gone. Really believe that intent (prompts & responses from AI) is going to be the critical artifact upstream of code and there is a need to capture all of it: what the AI suggested, what you kept, what you rewrote, and why. We integrate directly with AI-powered IDEs so your intent becomes as searchable as your code.

We started with Cursor and just shipped support for GitHub Copilot (Agent Mode). The long-term goal is to build a canonical intent layer for codebases built with AI—something like git log/blame, but for why things changed, not just what.

This is going to sound ridicilous. But in the past month, I have been working on an AI agent that can write its own AI agents. I can give it a task like: "Please create an AI agent that fetches the weather, and sends me an email every morning about some interesting stuff to do". The agent then goes through a loop of requirements gathering (with my input), and then starts building himself.

It self-references its own documentation, spins up a docker container and runs it. Alongside it builds tools, and registers both the agents and tools in a central system, so that it has knowledge of what other tools and agents it can use. I am not talking about "I am working on the theoretical idea of an agent that can build agent", but this is actually working. And I know of several other teams that are building stuff in this direction, its very fun.

I left behind a very well paying client to go full-time on this because its just so much fun. I have connected it to telegram, so now while I am at the gym, I can actually build software... the execution may take anywhere from a 10 minutes to an hour. Which is time spend writing and testing the code, then spinning up a docker container and fixing stuff, prompting me to create accounts somewhere an provide an API key. By far its the most complex project I have worked on, and all my friends and colleagues are slightly going crazy by seeing the outputs.

ok been quietly working on this thing for the past 5 months, and the reports finally hit the quality bar i was aiming for.

long story short: i built a system that scrapes a company’s site, profiles, press, and anything else it can find online, then runs it through a multi-model prompt engine i wrote from scratch (multiple LLMs chained together with custom logic). the workflow is split into three parts: crawl, process, synthesize.

output comes in markdown. all signal, no bs. useful for GTM, growth, competitor analysis, product gaps, strategic blindspots, that kind of thing.

i’ve been stress testing it on real companies. just pushed 2 sample reports to GitHub if you wanna peek:

- Grab (SEA unicorn) - LemmyHomes (early-stage Malaysian proptech)

→ https://github.com/lightyoruichi/numen-output

not selling it as a product (yet). backend still in dev. just doing reports manually for now while testing edge cases/validating if anyone wants this at all lol.

note: it’s not fully automated. i use the system to generate raw analysis, then apply human input to reframe, expand, or clean up weak insights. think of it like pairing with an AI researcher who works fast but lacks nuance/context, you still need a strategist to shape the output. there's tons more feature but at the core this is it.

happy to run one or two more this week if anyone wants a teardown. not free though (token cost’s brutal lol). DM if interested.

Crypto, Fiat, AI Ecosystem

I'm working on a new kind of financial infrastructure that combines crypto, fiat, and AI to make managing money in decentralized environments simpler and smarter. The core idea is to move beyond the traditional 'wallet' model and instead help people, especially in emerging markets, make better, more informed financial decisions using real-time intelligence and automation.

It’s designed for everyday users, not just crypto-native folks, and it focuses on things like streamlining DeFi, improving transparency, and reducing user fatigue. We’re building with scalability and user experience in mind — something that actually fits into people’s daily financial lives, not just trading.
