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

Iterating on an accessible color palette creator, for custom Tailwind-style palettes of multiple swatches, where you can check your colors have sufficient WCAG/ACPA color contrast on a live UI mockup. You can export the colors for use with Tailwind, CSS, Figma, and Adobe.

I started working on this because for design projects I was almost always getting handed brand style guides that were missing thought into accessible colors pairs and lacked tints/shades, where I had to fill in the gaps. There's lots of color tools out there, but this supports multiple swatches, checking the contrast of multiple color pairs at the same time and the HSLuv based color picker makes it easier to explore accessible colors.

It's really only usable on desktop right now but I'd love any feedback good or bad on if it's useful and what to work on next! There's actually a lot of directions to go in, and it's tricky to balance more features with keeping it simple. Some tips:

- The "Load examples" menu in the top-left lets you compare the colors from Tailwind, IBM Carbon and United States Web Design System.

- The "contrast" menu lets you see how WCAG 2 contrast checks compare against APCA when "vs black/white" is turned on. WCAG 2 has known inaccuracies, especially for dark mode. APCA is the candidate contrast method for WCAG 3 that's meant to improve on this.

- Use the "..." menu to create a swatch based on a brand color.

- Use the "..." menu to "flip to dark/light palette" to create a dark theme. Or just manually flip the lightness curves horizontally.

I'm a big fan of HSLuv and I've been looking for a way to generate 12 distinct colors for data visualization, so that small points in those colors against a black or dark blue background will be visually distinct to everyone including my red-green colorblind coworker.

seanwilson3• 2 years ago

I like HSLuv too as its color picker looks familiar while having a Lightness slider that works the way you'd expect compared to HSL. I see color nerds promoting OKLCH but OKLCH color pickers can look intimidating.

generate 12 distinct colors for data visualization, so that small points in those colors against a black or dark blue background will be visually distinct to everyone including my red-green colorblind coworker.

Did you get anywhere with this? When there's multiple kinds of color blindness changing the perceived colors in different ways, I'm not sure 12 colors that are distinct to everyone is feasible. You could use different symbols though, or changes in size or pattern.

trevor-e• 2 years ago

fwiw I was very confused with what I was supposed to do on this site and I run a few websites using Tailwind colors. I don't really get how the color selector on the right interacts with the mock previews on the left. It also wasn't obvious I'm supposed to hover over each element in the mock preview.

seanwilson3• 2 years ago

Thanks, that's helpful! The color selector on the far right is mostly there to let you change which color you're editing if you're not interested in the mockup preview on the far left, and to add new colors. You can mostly ignore it if you'd rather select colors by clicking on the mockup.

For what you're supposed to do, you're meant to drag the points or curves in the hue/saturation/lightness columns to customize the colors swatches to create your own custom palette. The mockup will update as you make changes and warn you if there's any accessibility contrast issues. You can click elements on the mockup to select colors to edit and check their color contrast.

Does that help at all? Any more hints on what part wasn't obvious and what would make it more obvious? I could hide the color selector by default maybe? Add better labels or hints?

This is an ongoing experiment that david927 has been helping with (thanks!). The two previous in the sequence were:

Ask HN: What are you working on (September 2024)? - https://news.ycombinator.com/item?id=41690087 - Sept 2024 (1041 comments)

Ask HN: What are you working on (August 2024)? - https://news.ycombinator.com/item?id=41342017 - Aug 2024 (1424 comments)

One thing I'd like to hone in on is that these threads aren't intended for promotion, but rather for the just-because sort of project, driven by idle interest or weird obsession—the sort of thing people might spend their free time on.

I'm not sure yet what the official "rule" should be (if any), but if you're working on a startup or have had attention via Show HN, maybe abstain from these discussions? It wouldn't be good for the thread to get taken over by things HN already has a place for.

david927• 2 years ago

Thanks, Dan, for that clarification. The question each month is actually two-fold: what have you been tinkering around with and what new ideas are thinking about. It's an invitation to dialogue.

We know our history and the role collaboration has played in it. Whether at Xerox PARC or Bell Labs, bouncing ideas off of other colleagues has spurred incredible innovation.

I submit that HN is a giant Xerox PARC. We have all of the ingredients for this recipe here on HN. We have the brilliant minds; we have the joy of creation. I submit that what we lack is mixing those ingredients. We lack dialogue and collaboration, and it's all completely unnecessary. It's here. Please use it.

kaycebasques• 2 years ago

waprin• 2 years ago

Why isn't it intended for promotion?

I find this "anti-promotion" attitude to be doing a disservice to this HN community for a few reasons.

Clearly, this whole website is funded and exists in part to promote YC's portfolio companies, as evidenced by "Launch HN" threads getting auto-front paged whereas "Show HN" plebians have to earn the upvotes from /new (which most agree required an exceptionally good post and a lot of luck to even get that goodness noticed). And we're not talking promotion of a few posts, YC is now doing multiple batches a year and has hundreds of companies per batch meaning we're seeing a LOT of promotion / advertisements on this site coming via Launch HN threads as well as jobs ad threads.

I don't think Xerox park would have done as well if 5% of the people get got the opportunity for a microphone in the auditorium every week and the other 95% did not. That would seem like a caste system. I understand that YC funds this website so the caste system is inevitable but I don't see why moderation should further stratify it - unless you're prioritizing advertising YC companies over a great community.

Next, I see this "HN is not for self promotion" do a lot of downstream damage on the community in the sense that it's much better for big, existing trillion dollar companies than smaller players. If a small bootstrapped startup writes a blog post and mentions there product, people will complain about "blogspam" and "this blog post is really just an ad for a link at the end". But if Google or Amazon have a new announcement for a new product, nobody complains that it's an advertisement, even though it's often as much or more one. The end result is that the website tends to focus more "corporate" news than "hacker" news as a downstream consequence of a well-meaning "no self-promotion" rule.

Finally, as we've discussed over email, the rules around self-promotion are extremely opaque and in many cases algorithmically enforced by closed algorithms. This leads to a lot of confusion around what's allowed and a lot of ambiguous favoritism.

I understand this site is called "Hacker" news and there's some mystique around the "hacker" building "just for fun" , the purism around intellectual curiosity that you don't want tainted by dirty commercialism. I just think that once the website has decided it's going to be the media arm of one of the most powerful venture capital firms in the world, the ship has sailed.If people really want pure tech news, they should go to https://lobste.rs/ . I've personally found in recent years quality of interesting conversation is much higher on /r/saas, Indie Hackers board, and Small Bets campfire, as well as various Discords, all because they allow self-promotion and don't encourage the "self-promotion police" who frequently show up aghast someone would try to make money on the internet (unless it's their daddy FAANG employer).

Another rule I've seen in various places be very effective is a simple guideline to contribute 10x as much non-promotional content as promotional content. If someone only posts links to their projects and nothing else, I see how that gets spammy. But if someone regularly contributes they should get a pass. I understand that's partially how the submission system works via algorithmic enforcement, but , see above about its opaque and ambiguous nature.

Show HN is a "place" for self-promotion but it's a pretty bad place if 99% of submissions get entirely lost and ignored and I think you should encourage more places for promotion without inflicting a caste system where only YC companies and certain golden children get special rules.

Overall, HN's guidelines against self-promotion are too rigid, there's too few opportunties for small players to promote, which makes the discussion here less egalitarian, more corporate, and less interesting. You'd be better served encouraging more self-promotion in threads like these.

mtndew4brkfst5• 2 years ago

Grindset self-promo tactics being pervasively, overly represented in the content submissions and discussions here are the number one reason I take very long breaks from the site.

More genuine conversations are intensely welcome, so if that takes overt guard rails, so be it. If the only enthusiasm someone really wants to share is about their capitalist endeavors, count me out.

oefrha• 2 years ago

There’s simply no “HN is not for self promotion” policy. You’re asked to not use your account primarily for self-promotion, and repeats are allowed, so you can roll your dice multiple times on your Show HN already as long as you’re otherwise a good contributor to the community and only do it sparingly. Flooding another topic with commercial promos simply turns it into another https://news.ycombinator.com/show, what’s the point then?

As for YC companies getting Launch placements, well too bad, it’s their site, you’re free to leave and start your competing one. I assume most users aren’t bothered — I seldom notice them and hardly ever click on them. I notice job ads more.

0823498723498725• 2 years ago

Dan, instead of "What are you working on", could a better title for conveying the intent be "What are you hacking on"?

hyperbrainer3• 2 years ago

That's good, but hacking for me has a specific connotation in that you are modifying something for your purposes. Something new is "working".

dang3• 2 years ago

It's a good idea and consistent with the original use of the term on HN. I guess the downside is if anyone with a cool side project thought that it wouldn't belong under that smaller-sounding umbrella.

Another option would be to go the whole hog and explicitly reference side projects in the title, or at least in whatever will become the instructions at the top of the regular thread.

paddy_m2• 2 years ago

I just saw this. yep, totally promoted my project instead of following this guideline.

dang3• 2 years ago

Hi Paddy! Hmm - I'm not sure. Are you talking about https://news.ycombinator.com/item?id=38424478? That doesn't seem to have had significant attention on HN yet. It's an open source project. It might be fine in this thread.

Whatever the line is, it's still gelatinous. We want to figure it out in a way that optimizes the thread for interestingness, which means avoiding repetition and prioritizing the long tail of projects that probably wouldn't get discussed in other contexts on HN.

Working on finding a job. Maybe in 2025 I can use these threads as a small devlog on the game I want to work on. But until then my progress has been "did questions on trees and backtracking". woohoo.

Though games for sale seem to be treading the line of the "no self-promotion" guideline. It's not coming out anytime soon and I have a very unconventional pipeline for developing it, so I think it'll be worth sharing the tech and process of that along the way.

I've been working on the idea of building synthetic workers. I'm trying to implement a planning workflow system for scenarios where the workflow definition, the environment, or the task are not well defined. I also ended up implementing a micro Palentir plugin system to support the action system for the synthetic users.

Its a cool project that gave me immense pleasure to built, however its unfortunately a intellectually masturbatory one, because although the tech is cool, I haven't found a cool application for it. If anyone is interested hit me up.

I'm trying to build a DNA assembly company right now (been lots of ups and downs lately...), and one thing I need to do is validate the specs of my oligo pool synthesis provider, Agilent, before I release to customers / raise a seed round. So as a stress-test run of my system, I'm synthesizing a genome, and am thinking about trying to livestream it. The unique technology is variety of ways to assemble and validate DNA from oligo pools for a lot cheaper, pretty much enabling a 10x reduction in DNA synthesis cost vs commercial suppliers. I've worked my ass off for nearly 2 years to get to this moment and am so excited!

Someday hopefully soon when I raise a seed :)

I think if you have the right structure, it is easier to train developers to be bioengineers than bioengineers to be developers! Bioengineering tends to be a more wicked discipline, which seriously affects how one writes their code. Makes it kinda crap. Software devs on the other hand typically aren't as experienced in the other field, and so are coming in blind.

That article is mainly their legal team fluffing their own feathers for their clients, which I'd hope that one would be able to read between the lines for, considering it was published by the lawyers themselves. The lawsuit itself is quite frivolous and accusing me of stealing and using source code I didn't steal/use, so just have to go through the legal motions to prove that. The more details you know about the case the more absurd it becomes

Pondering doing a hardware startup to offer a battery buffered electric kettle.

110 volt plug, 220 volt power.

(You could use the same concept for lots of other appliances too)

sshine3• 2 years ago

I have a battery-powered espresso machine.

It spends ~33% of its battery on one cup.

It sort of works if you bring pre-heated water in a thermo.

Heating water with conventional batteries is a terrible idea.

squidgedcricket• 2 years ago

Interesting idea! Supercaps might be a better fit than batteries.

binoct3• 2 years ago

I love the idea and thought I'd do a rough check on the math:

Assuming the goal is to match the power delivery of a high power UK kettle, looks like the batteries will need to step in and produce about 1kW of power for the duration of the boil, something like 50% on top of the standard 15A US circuit. I know on paper the circuit ratings are nearly 2x, but in practice it sounds like it's closer to 1.5x for the average kettle comparison.

80% efficiency for the heating coil, 1.6L of water, you need about ~750kJ (200Wh) get to a boil from 10C tap water.

So you'll need at least 70Wh output from your battery, and it needs to provide 1kW continuously. Accounting for conversion losses and some buffer to avoid deep discharge I'll target 80Wh. At 1kW that's a continuous 13C discharge rate, which is pretty high. Hobby-oriented LiPo packs will do it, but I'm not sure how they would hold up for consumer product safety and longevity. LiFePO cells could be a good choice since density is _less_ of a concern, and are readily available with 20+C continuous discharge.

I don't know my power electronics very well, so I'm not sure the best way to merge the outputs. Any conversions are going to eat into total power and thus boil time, just rectifying the AC will take 20%. Maybe it makes the most sense to have two separate coils, one direct from AC and a second from the battery? With smaller cells in series, say 10+, to get a decent voltage it could end up with a manageable current to use directly with the 1kW boost. In that case the only expensive power electronics needed would be to charge the batteries.

Also have to figure out how much recharge time matters to people, since by default it would be an hour or so.

It's going to have a chunky, heavy base, and guessing it will have to be pretty expensive for what it does, but I like it.

shiroiushi3• 2 years ago

The whole idea sounds pretty insane really. Who's going to pay hundreds of dollars for a battery-powered kettle just so they can save 1-2 minutes of time (and less if you're just making enough boiling water for 1 cup). I use a little 100V (900W I think, according to the label) kettle to make tea, either 1 or 2 cups at a time, and while it's certainly not as speedy as those EU/UK market kettles, and a bit slower than a US kettle, it's fast enough.

A battery-powered one might save me 1 minute of time at best, but will cost probably at least 5-10x as much for the kettle, it'll be MUCH larger than my current kettle (that battery pack and power electronics needs space) which is a problem with my tiny kitchen, and I have to worry about how long the battery will last and how to dispose of it later and if I can even replace it.

This is really a solution in search of a problem.

bilsbie5• 2 years ago

Thanks! Good calcs. As far as merging I was thinking simply two separate heating coils. One AC on lower voltage dc.

tmshapland3• 2 years ago

Updating some of my negative core beliefs. Years of Buddhist meditation only got me so far. But two months of this new technique, and I finally see a path to being able to program my emotional self like I program a computer. Here's how it works.

Step one. Identify the negative belief you want to change. This is the core belief. It is something you feel is true. For example, “I am a bad manager.”

Step two. Create a statement related to the belief that you believe is not true. This is the false statement. For example, “No employees Ive managed have thought I did anything right as a manager.”

Step three. This is the training step. You spend a few minutes following your breathe to quiet your mind. Then you think the false statement and watch the emotional reaction the mind has to it. The reaction is an aversion, a kind of disgust. Then, say the false statement and the core belief together. “No employees I’ve managed have thought I did anything right as a manager. I’m a bad manager.” Repay the false statement and core belief together again and again, watching how the mind rejects the false statement and that aversion feeling lingers as the core belief is thought.

Step four. Repeat the training step in daily sessions. During the session, repeated think the false belief and core belief. The session should last at least ten minutes. The daily sessions should be repeated for at least a week, and longer for more deeply held core beliefs. Over time, you come to reject the core belief just like you reject the false statement.

Here's why I think it works. There is a rational part of the mind in the prefrontal cortex. It is what we think with. But it is not where our beliefs are. We can rationalize our way to a new belief or to change a belief. Instead, beliefs are felt. And they’re felt in the limbic emotional part of the brain. The limbic system is mute and cannot think with words. The prefrontal cortex can’t directly talk to the limbic system with words. Instead, the prefrontal cortex must communicate with emotion. You have to train the limbic system to feel differently about a belief. You can’t use positive affirmations because they are not felt as strongly as aversion.

oidar• 2 years ago

did you come up with this technique?

tmshapland3• 2 years ago

Yes. Claude tells me it's a novel technique. It also tells me it's a dangerous idea to focus on negatives. But negatives are a more visceral feeling and have more weight in the training. The technique is working for me.

geoka9• 2 years ago

Does that mean you actually know that you're a good manager but can't shake off the feeling that you're not? And this technique is a way to achieve that?

tmshapland3• 2 years ago

well I know that I need to stop feeling like I'm bad at it. We all tell ourselves in so many different ways that we're not enough. This is a technique for training those beliefs away.

The text is written in simple language, it is then translated in many languages, and I generate audio files. This provides input for people learning a language, with multiple options to practice reading or listening.

I'm building a custom NC manufacturing robot from scratch.

I was unhappy with availability, pricing, and business model (SaaS lock-in) of the existing hardware/software solutions. But to my delight, I noticed that you just need better amplifiers to use 3D printer mainboards for driving industrial stepper motors. Everything is controlled with Gcode, which is just text. And sensors can send back logging messages over the same USB connection.

That means the control software can be just a python script with a little state machine inside :)

arunabha• 2 years ago

Interesting! The use of 3D printer electronics is a great idea as they are cheap(ish) and get reasonable accuracy.

I'm curious what you mean by a custom NC manufacturing robot? A CNC mill?

fxtentacle2• 2 years ago

No, its neither a CNC mill nor a lathe nor a robot arm. It's a specialised machine that automates one production step. But it needs to react to variations in the input work pieces, which is why it needs to be computer-controlled.

HeyLaughingBoy• 2 years ago

3D printer/laser engraver electronics are great for lots of things actually. You get

A (at least) 3-axis motion control system with G-code processor

Spindle controller (usually)

Limit switch input

A nice graphical display

(Sometimes) Wi-Fi or BLE

Arduino framework

All for around $50.

I was exploring the use of one for an open-source infusion pump controller. However, it turned out to be too bulky, but it would probably have been fine otherwise. Even after all these years, I was blown away by the insane amount of capability that I could buy for $50.

No, because Fil-C++ isn’t a new language. No new annotations. Just recompile your code and it’s safe.

Big problem with the video: the audio volume is very low, then I raise the volume of the computer to compensate for it and BAM! an advertisement comes up screaming at me!

I’m very interested in this so I’ve downloaded and extracted your presentation adjusting the volume (24dB!) with:

I'm building Pastmaps - striving to eventually be the world's largest online collection of old maps, aerials, and photos all packaged into a public historical research platform that's as easy to use as Google Maps. This has been a labor of love now for about a year, but I still have a huge mountain to climb to realize the full vision. Give it a try and give me your harsh criticisms - that's the greatest gift you could give me!

Even in it's current state, it's being used by geneologists, urban explorers, search & rescue teams, real estate developers, government agencies, etc. The number of exploding use-cases continues to astound me and keeps me motivated to continue.

Just be careful in countries like Japan where old maps sometimes are used illegally to discriminate based on caste (tracing ancestry of workers/candidates to discriminate against ones coming from certain historically lower caste areas of towns and cities). You might catch negative attention if your tool makes it easy to reference these maps

i like to bounce between projects week to week and am in a huge phase of just trying to build services i pay money for.

the first fun thing i'm working on a roguelite(?) type of petsim in dragonruby for my wife and i to play.

then i'll go back to working on my mtg collection / deck builder app. instead of rewriting in nextjs i decided to just go modern rails with it and i am honestly having a lot of fun. a redesign helps too, but once you get the hang of turbo/hotwire and stuff it really isn't that bad.

another thing i've got kicking is writing up a portfolio site for my old photography since that current hosted plan is about to renew. this is more of a stability and performance issue as i really liked using Format, but every single time i go to show my port to someone irl i would either not load or take forever or have images missing. extremely frustrating.

i'm very tired of SaaS pricing going up (with unwanted features) and user experience and value going down. reallllllly fighting the urge to just build a clone and try to take a cut of the overall business.

scottbez1• 2 years ago

I'm building a collator robot [0] to help me pack items I sell for building your own open source split-flap mechanical display [1].

I get custom character flaps printed and die-cut in bulk and then sell them in smaller sets. A full set of flaps for one module has 52 distinct designs (letters, numbers, symbols, etc) and I get them from the manufacturer grouped by design, so they need to be collated to sell as packs of 52 with 1 of each design.

My WIP robot will take a stack of one design and distribute them to a bunch of cubbies, then I'll swap in the next design, and so on, so each cubby ends up with a full set.

It's based on a cheap ~$110 CNC gantry frame from AliExpress and a ~$35 BTT SKR Pico 3d printer main board running GrblHAL. To detect whether the flaps feed successfully I use a visible light break-beam sensor (the typical IR sensors don't work because the PVC flaps happen to be IR transparent!) which acts as the "z probe" - the flap is fed via a G38.3 probe action which returns whether the probe was successful or not, and the "z" coordinate it was first detected.

I have a python script running on a computer to send the gcode to the machine.

I've been working on an automatic sky tracking telescope over the past few months. I'm a few weeks behind on blogging but making solid progress. V1 is nearing completion. Then I want to rework some of the electronics to design and get a custom PCB printed. Also the physical design needs a complete redesign to make it more sturdy for long exposures and solve some wiring pains.

The software allows the platform to automatically align to north and working on accounting for imperfect leveling (such as placing it on a slanted surface) through software and accelerometers.

Next challenges I want to solve in software is focus detection and then automatic image stack and post processing.

Primary goals of the project is a deep dive into robotics and electronics, along with brushing up on webdev which I don't touch too frequently being in the gamedev world. Also allowing me to explore things like digital signal processing.

I'm keeping a bit of a running blog here. [0]

LLM experiments.

mindcrime3• 2 years ago

For the last little while now, I've been spending a lot of my spare time learning to work with a language called AgentSpeak[1] using a platform called Jason[2].

Briefly, Jason is a platform for building intelligent agents based on the BDI (Belief-Desire-Intention) software model[3], which is in turn based on the Belief-Desire-Intention cognitive model[4]. Broadly speaking, it's an event based programming model, where "events" are things like "gaining a new belief", "dropping a belief", "selecting a plan to execute" (aka an "intention"), etc. AgentSpeak programs (normally) run "forever" cycling through a "reasoning cycle" that involves perceiving the world, updating beliefs, choosing intentions, executing intentions, communicating with other agents, etc.

And to commit a little self-plagiarism, from a recent post on LinkedIn:

----

On the one hand, AgentSpeak is basically a logic programming language with a lot of #prolog in its heritage. On the other hand, the runtime is all Java and to do anything interesting you have to write your custom Environment class and other helper functions in #Java. And while the interop is seamless in a way, getting your head around the execution model and knowing what's really happening at runtime can be a bit tricky.

Still, it's starting to make sense. And I do think this #BDI inspired approach has a lot going for it. I'm just looking forward to getting to the point where I can really start to exercise this. I have a few things that I want to accomplish soon:

1. I want to create a BDI agent that I can connect to an #XMPP server so I can talk with it from anywhere.

2. I want to start working on customized perception, using neural networks and various sensors (web-cam, microphone, accelerometer, distance sensor, etc.) to create an embodied agent that can truly sense its environment.

3. I want to take a stab at integrating some symbolic reasoning. I've given thought to trying to adapt the "belief base" to be an #RDF triplestore (probably #Apache #Jena) and include a reasoning engine or two. This all starts to get really speculative from here, but I spent a lot of time working on abductive inference a couple of years ago, and I'd like this thing to be able to use abductive inference, along with deductive reasoning, rule induction, possibly case based reasoning, etc. all in one system.

4. Might experiment with implementing a #Blackboard architecture and have specialized "problem solving" agents that collaborate by using the Blackboard in some situations. What would be really interesting here would be to figure out how to seamlessly translate in and out of a structured representation that lets you use existing specialized code for things like, eg. R for statistical operations.

5. And of course, experimenting with continual learning, as opposed to the "batch training job" stuff that we all use for ANN's today. This gets really speculative as well, but I want to explore contrastive learning, Hebbian learning, associative learning, operant conditioning (ala Pavlov), etc.

[5] above is why you'll see me spending as much time lately with Developmental Psychology, Infant Development, and Cognitive Psychology books, as with "AI" books per-se. I still believe that getting an AI that can learn from its environment, and build up useful mental representations with the minimal set of hard-coded behaviors, will be the best way to make progress with regards to #AGI.

----

I didn't mention it in the LinkedIn post, but as part of all of this, I've been building a hardware platform for some time now as well, where said platform is meant to support "perceiving the environment" so the system can learn from the physical world. It's not finished yet, but today it includes a GPS receiver so it can "know" it's location in physical space, a 6-DOF accelerometer/magnetometer/gyroscope board so it can sense movement (of itself), and two microphones (for stereo audio input). Future plans include one or two webcams to emulate vision, and possibly some other sensors: IR and/or ultrasonic distance sensors, temperature sensor, humidity and barometric pressure sensors, etc.

Also in the "speculative / for the future" category: AgentSpeak programs don't have any inherent notion of learning built into the model. All "plans" (aka "desires" or "candidate intentions") have to be coded by the developer up-front. This is obviously pretty limiting if you're trying to create truly autonomous agents, so another area I want to dig into is how we might combine work on "AI Planning"[5] to dynamically create new plans.

And since this has kind of turned into a big brain-dump of stuff that's on my mind, I'll finish by saying that I've been chewing on some ideas about explicitly modeling other "mental states" that aren't part of the base BDI model. Things like "attitudes", "values", different emotional states (eg "boredom", "frustration", etc.), "curiosity", "confusion" / "cognitive dissonance", and so on.

A new timeline drops every day and I have a lot more planned to take it beyond the simple blog format it's in now but it has been a fun challenge to learn how to do some deep prompting with AI to generate random entries without veering off into crazyiness or getting locked onto the same thing over and over again.

Now I'm rewrite it all because I want to do type specialization: I'm implementing "Simple and Effective Type Check Removal through Lazy Basic Block Versioning", which is used as the basis of Shopify's YJIT for Ruby. I have a decent idea of how it needs to be implemented and have a prototype kinda working, although some of the jump targets are still wrong right now. Once I get it all sketched out then I'll have to scale it back up to a full Lua implementation again, and then I'll add table shape specialization afterwards (which is a bit trickier, and outlined in a sequel paper).

A new YouTube app/player, for my kids.

It allows us to control the algorithm. It’s all LLM translating to YouTube search queries under the hood.

Visually it looks the same.

The suggested videos come from predefined buckets on topics they love.

E.g. 33% fun math, 33% DIY engineering, 33% creative activities.

Video recommendations that have a banned word in the title/desc don't get displayed e.g. MrBeast, anything with Minecraft in it, never gets surfaced.

For anyone interested in using it, send me an email.

jim.jones1@gmail.com

aantix7• 2 years ago

YouTube recommendations for kids shouldn't be driven by engagement (e.g. "oh, you watched 20 hours of MrBeast videos. You probably need another hour.")

If my kid watches an hour of unboxing toy videos, I shouldn't have to try and disable 3,000 channels of toy unboxings in an effort for that topic to never surface again.

The thumbs down button essentially has zero effect.

https://www.wired.com/story/youtube-dislike-button-mozilla-r...

Diversity of thought and topic is much more critical when they are kids.

aantix7• 2 years ago

Todd Beaupré, the product lead for the YouTube homepage, says "We love exploration, have multiple teams dedicated to it."

But from my kids' viewing habits, I don't see it. The algorithm is seems super narrowly focused.

I’d go further and say nobody should be subjected to this stuff. Engagement is a euphemism for addiction. Self improving addiction machines are a horrible idea. They’re actively bad for people and society for a laundry list of reasons.

This is a great idea! Recommendation algos are weaponized against kids and would be great to have some way of managing it. There is a similar problem with movies as well. It is hard to know whether a movie is appropriate for a child e.g. some kind of violence may be acceptable but not adult themes. So marking a movie PG-13 for example doesn't help much. There are some crowd-sourced solutions to this right now such as https://www.commonsensemedia.org/movie-reviews But LLMs could really help automate this

Building a VR IFC viewer in C++ without external dependencies.

I just implemented a parser for IFC, and am now looking into extracting BRep and CSG geometry from it, convert that to meshes, and write a simple renderer for Vulkan.

My approach is to write really scrappy, simple code with minimal abstractions.

The hypothesis now is that for generating meshes from BRep, you don't need an entire CAD kernel, as a CAD kernel seems to be focused also on operations, but this will probably lead to a humbling experience and walking back to using either OpenCascade or licensing a commercial kernel like Parasolid.

My goal is to have a simple prototype out before the end of the year, but work might get in the way :)

I'm writing a build tool for SQL. I like to write SQL directly and to use it's more powerful features (like stored procedures and Postgres' ltee extension). But this is gets difficult to manage in a linear, "migrations" based workflow. I want to edit a file tree organized by topic, not a series of scripts run in order. Which is to say, I want to edit it like I would any other codebase.

I've written code allowing me to express dependencies between .sql files and to concatenate them into one big .sql file that builds your schema. I'm working on interrogating the systems tables of the database to analyze the difference between successive versions of a schema, to automatically generate simple migrations (like adding a column or renaming a stored procedure). Eg, `sqlite_master` in SQLite, and `information_schema.*` in Postgres.

First iteration may be box is rpi based and local LLM runs in another room on beefier machine (or even before that just get it working with a cloud Llama).

What would make this cool is to use MemGPT for memory so you can talk to it Monday and then it remembers what you said Friday.

Being all local it could be always listening.

since I'm in no hurry + my career is going down the drain, I will try to do my best and power up my software engineer skills.

Autopilot for my sit-on-top fishing kayak. Designed, modeled, and printed an assembly which attaches to the rudder rod. Moves the rod via a stepper motor connected to a Teensy 4.0 which gets NMEA 2000 messages from a Garmin heading sensor and a Garmin fish finder/chartplotter. Uses PID control to maintain any course I set on the chartplotter, using the cross-track error and heading. I’ve had it out on the water a few times now and it works great. Also put together an iOS app that communicates with the assembly via BLE so I can modify the PID gains as needed depending on conditions.

There was a bit of noise to the sonar transducer since the stepper motor was so noisy, but I mostly eliminated it by routing the motor wires through liquid-tight flexible electrical conduit, connecting the conduit to ground.

I have! Mill is a lot more thorough, handling things like caching and parallelism for you. BLD is a lot more minimal, which would be fine for small projects but maybe not for larger projects as they grow

I’m working on a zine. The first issue is on system evals for LLM-driven apps. It’s set in a world where Bear and Fox are opening a cafe with an LLM shoggoth generating custom recipes.

Lots of people just going off of vibes to see if their system is working right. That’s a good start, but you’ll need system evals to systematically improve your app. Like Garry says, “don’t raw dog your prompts. Use system evals”

muhrizqiardi• 2 years ago

F*ck it, I'm not gonna sugar coat it.

I was supposed to be working on a project called Tagbox... but it feels like it's never gonna see the light of day. I hope I'm wrong though, I still want this to succeed, for once in my life, I want to actually succeed on at least one thing. I want to contribute some good thing to the society.

First, what is it? It's a bookmarking app alternative to Pocket or Raindrop.io. Yeah, you can already tell it's not the most original idea. What makes it different, though, it's supposed to be self-hostable and additionally it's easy to deploy as it's only single binary file with no other runtime dependency--the database uses SQLite, which you can include it as a library in Rust.

What problems I'm facing while developing this? Honestly? I don't know, but I can't finish the last 10% progress of the app. It's funny--I first wrote it in Go, and it almost reached MVP. But, instead, I decided to just rewrite in Rust. Well, at least I got to learn new language while building this app, two birds one stone, or in Bahasa Indonesia, swimming while drinking water.

But now, I just can't force myself to continue. And I don't know why. Maybe perfectionism? It definitely doesn't have to do with skill though.

There are also another thing I'm working on: recovering from depression. One year ago, out of nowhere, I lost all my motivation doing anything--including university. I lost all my friends. Since then, I'm at the lowest point of my life. I visited psychiatrist multiple times. I don't know if it was effective, but recently I'm starting to see a light at the end of the tunnel.

The Tagbox Project is also one of the efforts for me to recover from depression. The depression phase made me realize that I _want my works to have a positive effect on the world, even for just a little bit_. I don't want my skill to be used for evil companies that throws away moral and ethics. Specifically AI stuff, but that's OOT of this thread.

Here are the links if you're interested,

Hey there. Been where you have been and can safely say, there is always a way out of it.

Sounds like you just need a bit of consistency to make some progress. I'd be down to chat once a week for 15 minutes and we can figure out the focus for the week. Hit me if you think that would be helpful, sounds like you can build some good stuff.

tehs2• 2 years ago

If there's one thing I've learn over the last few years is that it's incredibly difficult working on a project when you don't have peace of mind. It can be difficult working on something or staying motivated when you're battling depression, or if you're sad, don't have friends, or if anything is troubling your mind.

I've been there and I know what it feels like. I would try to perhaps solve the mental health problem first perhaps before tackling big projects. Maybe try gym, hiking, somehow finding friends, talk to more people, solve your sleep, eat better - something. Because again, if you don't have peace of mind, working on a project is difficult (at least for me it is).

Hope that helps.

GoToRO2• 2 years ago

Even without the other problems, I can assure you that the vast majority of managers will think that a 80% done project is almost done. The truth is the remaining 20% is where you have to fit everything together so you revisit an rewrite most of the project. It's a different kind of work that feels boring because you already did those things maybe 3,4 times already. It helps to understand the phase of the project you are in, to reduce the frustration. It also helps to do something even very small, every day and focus on that. One day you will run out of things to do.

takinola2• 2 years ago

Seems like you are discovering the truism that the last 10% of a project takes as much time as the first 90% of the project. In my experience, it is always a slog to ship a product. What you are feeling is normal and the experience of many developers. You should plan for this part of the project and figure out ways to motivate yourself to ship something.

It took a long time to train myself to ship at the 80% mark and simply walk away to let it germinate. Over time, you cultivate a garden of nearly-done projects that are all ripe for expansion or rewrite.

I built CryptoGain, an (currently) android app for cryptocurrency market tracking and analysis. Started it after getting frustrated with the limitations other apps put on technical analysis features behind premium tiers.

It offers:

- comprehensive technical analysis tools without artificial limits or cost

- customizable price alerts

- portfolio and watchlist management

- live market data across major exchanges

- available in 15+ languages

Currently serving a few thousand users and actively iterating based on feedback. The focus has been on making advanced trading tools accessible while maintaining a clean, intuitive interface.

rakejake• 2 years ago

A long dormant side project of mine to design a realtime raga [1] detector.

For the uninitiated, it can be roughly seen as detection of a sequence of musical notes. Raga is a term for a particular scale of notes (both ascending and descending).

Until now, this has mostly been in the domain of research and there is a ton of published literature out there. At the very basic level, if you have just voice, it is trivial to apply a pitch detection algorithm like YIN to get a pitch estimate and then analyse the sequence to figure out the raga. This doesn't work as well in a concert setup where speeds are higher due to gamakas, different instruments are used alongside and counterpoint melodies may make the music polyphonic. A lot of papers apply a variety of ML models (neural nets and otherwise) using several different features (cepstrum and mel-cepstrum, pitch distributions etc) with varying results.

So this is an interesting exercise in Signal Processing and Machine Learning. If anyone else is working on or has worked on this, I'd love to hear from you.

Putting the finishing touches on my LLM based town simulator. Once it's finished I'll have it simulate 4 hours in the town every 2 hours in reality.

It is designed to solve the problem of "RPG hero just killed a dragon in front of the town and no one says anything about it." All the NPCs realistically react and talk about the Hero's exploits.

Visitors to the site can vote on what quest the hero undertakes next.

I'm running into the problem what the site isn't much fun. I'm honestly not sure what to do about that!

An only slightly buggy build is at https://www.generativestorytelling.ai/tinyllmtown/index.html

Importantly, I am aiming to have everything (except voice gen) working on a small model that can be ran locally.

esperent• 2 years ago

Nice idea, but right now the villagers mostly say some variation on "I eagerly await the valiant hero's return!". Beside the fact that no villagers would ever speak so formally, this seems to fall into the standard fantasy problem that the normal people in the world only exist to further the hero's agency. Could you give the villagers a sense of their own agency, meaning that they have lives of their own that would continue whether the hero returns or not?

com2kid4• 2 years ago

Could you give the villagers a sense of their own agency, meaning that they have lives of their own that would continue whether the hero returns or not?

Yeah I'm currently considering working that in.

Right now existing game AI techniques can manage giving NPCs a daily routine, and I'm trying to focus on demonstrating something new, VS another solution for an already solved problem. But having NPCs just talk about the hero is boring. I'll likely get around to adding private life stuff for each NPC before I do an announcement and share the project more broadly.

This sounds nuts…and exciting. Makes me want to tinker with small models, what a neat concept.

meheleventyone• 2 years ago

Having played with the demo a bit I think it's a couple of things:

1 - If you hadn't described your technical choices above I'd think this was just done using normal procedural text generation. Every NPC feels like it's giving the stock phrase they'll say when you run out of dialog options.

2 - There doesn't feel like there is a narrative, reasons to care about these NPCs, reasons to care about the Hero, or some sort of character development over time. If you want to engage people you need to get them to care about what's happening.

com2kid4• 2 years ago

If you hadn't described your technical choices above I'd think this was just done using normal procedural text generation. Every NPC feels like it's giving the stock phrase they'll say when you run out of dialog options.

During one iteration of testing the NPCs decided to throw a party for the hero and they all congregated in the tavern. That was 100% awesome and if I can hit that type of WOW factor more often I think it'll all feel magical.

There doesn't feel like there is a narrative, reasons to care about these NPCs, reasons to care about the Hero, or some sort of character development over time. If you want to engage people you need to get them to care about what's happening.

This is just a tech demo so I'm not sure how much I want to put into it. Especially since the end goal is to get a recognized and get a job!

seidleroni• 2 years ago

It would be great to give each of the NPC's their own character. For example, some of the NPC's could have a grudge against the hero for reasons of their own. They could be cheering against him for causing such a ruckus in their village, or maybe some "Monday morning quarterback" happening, thinking they could have handled the problem much better than he did. I think an LLM may be pretty good at coming up with some ideas. Or maybe even make it a bit tongue-in-cheek and have some of the NPC's be fans of the hero's enemies.

com2kid4• 2 years ago

I'm thinking of going full on soap opera complete with a love triangle.

It looks interesting. Is the Basti EC2 instance deployed in a private subnet? Do you have a high-level diagram?

BohdanPetryshyn2• 2 years ago

The diagram is available in the basti-cdk package. Probably, I have to make it more visible in the main README: https://github.com/basti-app/basti/tree/main/packages/basti-...

By default, the instance is deployed to a public subnet but any ingress traffic is not allowed by the instance's security group. This is needed for the instance's ability to connect to AWS SSM service (egress only).

The user can also deploy the instance to a private subnet but this would require them to manually ensure connectivity to the AWS SSM via NAT gateway, VPC endpoint or other means.

We're working on a specialised graph compiler for speeding up simulations and computing derivatives automatically (backpropagation/adjoint differentiation). It now supports C++, Python, and C#; AVX2 and AVX512 instruction sets, multithreading; Windows, and Linux.

Essentially, it allows model developers (such as quants in finance, engineers, and ML specialists) to code in Python without needing to think about the performance of repetitive calculations. As we all know, Python is one of the least efficient languages when it comes to complex calculations/simulations - and we help to resolve it. Long story short, with very few tweaks to the code certain types of calculations (such as pricing of derivatives, curve building, computing financial risks, or "small" NNs) can be accelerated by 100+ in Python and x20+ in C++/C#.

We're now looking to add support for Java (but it doesn't have Operator Overloading, so it's tricky), and some customers are asking to support GPU - which is a bit tricky because it's got a closed instruction set.

I've been working on some projects in Rust relating to image processing and rendering. I'm between a few projects at the moment though but the biggest one is an image processing application I've been working on for quite some time. A lot of stuff I've programmed and learned about over the last 3 years has been leading up to the goal of making something like this haha. I wanted to leverage OpenCL for compute but I had a lot of trouble getting OpenGL OpenCL interoperability to work.

A big motivation for such a project is my passion for photography. I've taken many thousands of photos over just the last 2 years alone. A lot of them are digital, and so far a few dozen rolls of film. A big challenge for me is that I'm not satisfied with the tools available to develop the raw files that are free or open source. Either they're quite finnicky, or they have noticeable issues with color transformations.

I've done a lot of rendering projects over the last few years relating to color that have been focused on getting a better understanding of working with color spaces. Lots of 2D and 3D fractals haha.

Unfortunately I've had quite a turbulent life the last few years so development is very off/on. Every autumn for me seems to be a period of change, this one no different as I'm moving and I'm a bit uncertain of things. However, a side project to all of this has been an OpenGL project where I'm working on things related to voxels! I did a lot of research on data structures like interval trees, octrees, segment trees, etc. It does seem that a lot of people jump for the octree approach, however I've been able to render a lot of voxels with just a hashmap of chunks and a 3d array haha (albeit, mostly initial implementation of chunk generation, single threaded at that!). With this I'm hoping to explore OpenGL compute as I intend of generating world geometry in compute shaders :D

I havent published a project in a while and I'm hoping to get back to putting things out there, so hopefully some of the stuff I've been working on goes well and I can put it up on GitHub or something

escapecharacter4• 2 years ago

When you say "develop" a raw file, do you mean convert it to a viewable colour space, given a known screen? Like HDR or some other type of choosing the exposure/gain?

Re: 3D, are you aiming to infer a 3D scene from a single photo? There's a few approaches for that, but they tend to show off the examples that work well, and conveniently avoid examples that work poorly. But depending on the content of your photos, you might find an algorithm that works out of the box.

For data representation, we used a sparse voxel representation of a Truncated Signed Distance Function to represent surfaces for this project: https://www.microsoft.com/en-us/research/project/kinectfusio... However, I can't recall interacting with the sparseness; that level of abstraction may have already been resolved in the code by the time I got on that projects. TSDFs are cool as hell and way more interesting than representing ambiguous surfaces with mesh triangles.

Also, I've been there with the turbulence a couple times. Sometimes months happen in a day and vice versa ;)

An entity database (rest api on postgres so dB is a stretch) with a crud frontend for platform engineering. Adding a similar control loop to kubernetes and bash script (or executables) as the extension language.

This way you can write all of your glue code into one platform and create an IDP at the same time.

This came from a lot of situations where I'd need like one random thing to be stored in a database, but adding that complexity is a bit of a hump for just one thing.

Also crossplane is a really cool idea but starting a kubernetes cluster so that you can manage infra sounds insane to me, even as an avid kubernetes fanboy.

I'm working on ways to allow developers and deployers of LLMs to express how and why their overall system is compliant and adversarially robust, and what to do when that's not the case.

Specifically, my team and I are making assurance cases and ontologies that can seamlessly integrate with the system and its guardrails. For example, if you want to deploy some mix of filters underneath a user-facing LLM app, you would able to: 1) express the logic of how they should be deployed and why (e.g., if X=1, then Y, else Z); 2) see how they perform over time and evaluate alternatives; 3) investigate what happened when an attack succeeds; 4) prove to the auditors that you're taking all measures necessary to be robust and compliant with the EU AI Act.

It started as an informal collab early this year, but we have since published a few workshop papers on this concept [1,2]. We're building a Python demo that would show how it all fits together.

Originally, I built Pictera for myself to use because I couldn’t find any service that produced decent photos. Besides, I was very concerned that popular products in this space included broad terms allowing them to keep and use users' photos indefinitely for any purposes, including marketing [2]. But I've been enjoying working on the product so much that I've put way more time into polishing it and thought others would find it useful too.

My background is Risk Management, I am trying to gather an understanding how such LLMs report their "decision" for applications in human/ai interactions for identifying and reporting governance flaws.

Since I am working on autonomous agents that are given the agency to take an action on their own, I believe having a good understanding of the "psyche" is important (at least to me).

I’m building a way for developers to easily deploy open source applications (Postgres, redis, sentry, elastic search, etc), plus have a full heroku like workflow for their own applications, all within their kubernetes cluster, with what I hope is a super intuitive and friendly UI.

I’ve ran a start up and saw how SaaS-ified and expensive web tooling is (heroku, datadog, redshift, fivetran, etc), but how difficult it was to move off of them. We had a few years of over 1 million in infrastructure spend.

I’m hoping just making Kubernetes easier to use gives us a way out.

It’s fully open source and a hosted version is free to use! https://canine.sh.

This needs to know your location in order to compute your local sunrise and sunset, so don't freak out when the browser asks for location permission!

I’m fortunate to have this paid leave and a job guarantee, but it’s been a revelation stepping away from out all for so long. For the better, even though I’m exhausted.

I've completed the draft of Part 1 of my online book "Automated Agents: How effective chatbots work"

I'm writing about my experience building a chatbot at a startup as engineer #1. It started as a blog post, but I had so much more to say. This is the information I wish I had before getting started. A lot of information on the web is about building a wrapper around LLMs, this is one that we built ourselves and were able to resolve millions of customer issues with.

I am working on the Vanta for sustainability and climate disclosures. Climate and sustainability disclosures are starting to come online in many sectors and parts of the world. We offer compliance-as-a-service so that startups and covered entities can fulfill their compliance requirements in a mostly self-serve manner without having to hire expensive consultants or undergo significant restructurings. Our platform provides a single source of truth for your climate, sustainability, and emissions data. For example, if you are an American company trying to go-to-market in Europe, all it takes is purchasing an additional module and we will automatically generate the compliance documents and checklists for you based on the existing data we have on your company. We also offer managed “Climate Trust Center” dashboards that you can subdomain on your website for investors reporting and to satisfy disclosure requirements.

If you are in an EPA-regulated (or equivalents in Canada and Europe) industry (such as mining, oil and gas, minerals, rare earths, metal processing, airlines, construction, shipping/marine, logistics, heavy industries, agriculture/farming/food production, data center, power generation including renewables, adjacent ones like consumer goods, real estate, large scale AI training, climate derivatives etc.) or require sustainability consulting support in general, we would love to talk to you: hello@carbonimpacthq.com (put “HN:” in the subject line so we know where you are coming from)

I'm building Reasonote, a platform where you can learn anything with personalized, interactive lessons, and podcasts.

Imagine a fusion of Duolingo, Spotify Podcasts, Anki, ChatGPT, and Claude Artifacts.

We have custom AI-generated podcasts that generate faster than NotebookLM, that you can queue up for yourself. (Many more features coming here soon -- like more engaging podcasts and better voices)

Our classroom mode can generate interactive lessons, complete with an AI tutor, on any subject.

Flow mode allows you to practice deeply, with infinite activities to test your skills.

All of this is driven by a dynamically generated and continuously updating "Skill Tree", which keeps track of the domain you're studying, and your progress within it.

Several things:

1. Working on a 'production ready' version of Conal Elliot's 'compiling to categories' for GHC.

2. This is so I can create a vectorizable model of a datalog-based query language I'm building in Haskell.

3. The query engine will be using a version of monadic optimization as outlined on a blog post somewhere

4. The purpose of the query engine is maintenance of large datasets, all the more important with AI these days, but really general purpose.

5. The motivation for this was a low code tool I had built in Haskell almost a decade ago that I abandoned that I'm bringing up to use ghcs web assembly backend and I need a proper query engine for it now.

Other things:

1. Thinking about binary neural networks and how to train them stochastically.

2. Learning about finite element methods for physical modeling and also reviewing my basic topology so I can think more about non discrete math and algebra which I tend to focus on.

3. I'm building a cloud chamber! Because I want to see space particles. Literally for no other reason than I'm obsessed with these devices ever since seeing one at the exploratorium

4. And raising three kids. I don't know how I have time for anything

tobinfekkes• 2 years ago

I have one e-commerce system that ships boxes of organic coffee to people's homes all over the United States.

I have another ecommerce system that delivers boxes of organic produce all over the Seattle region.

So I am working on building an integration between the two systems. When a box of coffee is being shipped on the same day that the delivery company is already going to that region, redirect that box's fulfilment process away from USPS/FedEx and deliver it instead.

This saves 50% on shipping costs for the coffee company, and the delivery company gets paid for utilizing extra space in the delivery vans. It's been 4 months of work so far, and most of the individual pieces are working in production right now, hoping to enable all of it together this week or next. Just in time for the holidays ;)

The hardest part so far was integrating all the custom label generation, and mapping/routing so that it's seamless with the existing workflows of each company. The coffee company doesn't have a "separate" workflow for the new non-shipping orders, and the delivery company doesn't have a "separate" workflow for fulfilling orders they did not pack.

The real cherry on top is that it's built in such a way that N number of stores could integrate their stores into our fulfillment. This lets many local food producers who cant do their own fulfillment still participate in the local food economy without having "scale". It's kinda like an upside down Fulfillment By Amazon: they'll do your delivery for you as long as you sell through their store (and take their ever-increasing cut of the sale). This version lets the store owner maintain their own store, URL, branding, prices, availability, customer relationship, and margins, but then hook into our last-mile fulfillment.

I created KopiMap (https://kopimap.com) to help people discover great cafés in Jakarta Indonesia, but I wanted to take the UX further by automatically organizing user-submitted photos into meaningful categories (menu, food/drinks, ambiance).

The challenge is how to classify images as cost efficient as possible without compromising performance. I decided to go with running ML models on the client-side.

Technical implementation: - Built and trained a compact TensorflowJS model (~3MB) that runs entirely in-browser - Model lazy loads only when users are submitting reviews - Classifies uploaded photos into Menu, Food & Drink, or Vibes (interior/exterior) - Zero server costs for inference, quick enough classification feedback

This approached solved several problems: 1. Reduced server costs by moving inference to the client 2. Improved UX with immediate photo categorization 3. Maintained app performance by lazy loading the model

Would love feedback from the HN community on: - Optimizing the model size further - Alternative approaches to client-side ML - General UX improvements for local discovery apps

I had no prior ML experience, so this was a fun challenge :)

Hiya, Most other competing products only offer one or two components needed for building a robotic system. You end up spending time and money building "shim" hardware and software to connect different components from different manufacturers.

Our main product is a whole, networkable system that aims to cover most of the things you need to build a high performance robot. It is pretty straight-forward to add new components and integrating the software into your project is just including one library. Thanks very much

I'm still working on https://reciperium.com where people can write recipes with a custom language and create forks of other recipes and modify them.

I'm currently working on supporting images on the recipes.

I'm proud of having launched on producthunt and now trying to figure out how to attract more users

taulien• 2 years ago

It's nice! A few notes: I think, the ability to read the comments of others, who have already cooked a recipe, would be great! Additionally, it would be great to have the possibility to group ingredients, since many times you start with creating two ore three independent mixtures, that you only combine in the end.

My gut feeling, for attracting users, would be to just optimize the recipes to be found by people via search engines. It's great, that you are currently adding images. This is, I think, pretty important for deciding, if I want to cook something or not.

woile3• 2 years ago

Thanks for the feedback! Really appreciated.

Regarding the comments, I'd really like to implement activitypub on reciperium. To add the ability to follow users and comment on recipes. And to be able to comment and follow from the fediverse. It's a good opportunity for me to explore the protocol.

What do you mean by combining ingredients? You can currently link to other recipes. So if you make a sauce, that can be a recipe on its own, and it can be linked from another recipe. See this for example: https://www.reciperium.com/rodriguezflors/roti

My gut feeling, for attracting users, would be to just optimize the recipes to be found by people via search engines

That's a good idea, I'm optimizing a bit the search engine now. I've been also thinking of writing a blog

At work, busy adding internationalisation and localising an Angular 16 application. Figured out you can do runtime language switches, without having to maintain separate builds for each locale. Angular's documentation is rubbish.

In my spare time, building an OpenAI wrapper to create SEO meta descriptions for websites. It's mostly a tool for me to use because at work the marketing people don't do this very well and I am too lazy to do it with ChatGPT (copying the prompt and setting it up every time). Plus, the API is way cheaper for me to use. Building it with Laravel and InertiaJs is so much fun. The marketing people at work said they'll find a tool like this super useful, so I already have a user haha.

I'm building a wayland sleep and gamma handler that has lua scripting integration. It bothers me that it's so hard to set different timeout handlers. So I recently integrated wljoywake, which allows me to handle timeout on joystick commands and am in the process of adding flux like functionality.

The reason why I want scripting is between I want the color to pause while I'm playing videos without having to add scripting logic to other tools.

I'm also planning to add rofi like functionality with layershell. Rofi is the only tool that has first party support for keybindings and other functionalities, but it's all done through strings. I'd rather have a lua scripting interface that can call other scripts and communicate with json or something similar.

I continue to work on BoltAI (https://boltai.com)

It’s a native macOS AI chat client. I started it last year and didn’t think much about data synchronization. I didn’t want to store user’s data server side for better user privacy. So I decided to store all chats in a local SQLite database.

It works well but unfortunately without a sync engine, users won’t be able to continue the chat from a different machine.

I’m working on supporting cloud sync now.

redrove• 2 years ago

I bought BoltAI and I’m using it on two machines almost every day. It’s a great little client!

Minor nitpick to a fantastic app otherwise.

I'm building a simple app to let friends and loved ones know how you're doing. I know many people in some of the current troubled regions of the world, and whenever a particular event happens it's really nerve-wracking for those of us not there, wondering if our loved ones are okay.

WhatsApp and messenger groups don't work for this kind of thing because 1) people are often members of many different groups that they would have to constantly notify if they were "okay" during a particular event and 2) many troubles in the world are ongoing, and constantly spamming a message group saying "I'm still okay" doesn't work.

My app just lets people hit a single button to tell any interested friends / family that they are safe. They can do this as many times as they like.

Normally I would be worried about premature optimization, what I've been spending extra time making the tech stack initially very performant. It's working for my family but once I deploy to the world I want it to be solid and stable, or it loses a lot of its value.

I've noticed that my son spends way too much time on YouTube or playing Minecraft and one of the few offline activities he enjoys doing on his own is coloring.

At one pre-funding startup (in the days when 14400 was an excellent remote connection) we had a LAN set up in the basement of the founder with the largest house. Their daughter liked to "work" alongside us, so (partly to protect our unattended keyboards!) I bought a colouring-book program for her to use.

One evening, when her mother called down that it was her bedtime, she replied:

— Can't mom, busy working! click click click

— What are you working on?

— click I have to turn it all orange! click

Upon hearing that, we knew she was one of us.

Don't know if I'll have the chance to finish, but I'm sure Kindle will integrate this into their new color kindles (and probably every other e-reader) at some point.

Amazing! My son also colored a lot but he'd pick only a few pages out of every coloring book so I got the idea to find some online; one-page things to print but the ones I found at the time claimed to be "coloring book pages" but were actually more black-lines-on-white-background actual artwork. Much too complex for simple coloring. Your site would have been the find of the decade!

I'm still working on Habitat. It's a self-hosted social platform for local communities. The plan is for it to be federated, but that's a while off yet. I want it to be easily installable for those who want to host using docker, and for those who want to host on an EC2 instance or something, because online services for docker hosting are quite expensive, so I've been working recently on ansible setup, and it's proving quite difficult, so if anyone with the experience fancies helping out, I'd be more than happy to receive contributions.

I like the idea and have been ruminating on something similar myself - starred!

carlnewton6• 2 years ago

Thanks so much! I work on it almost every weekend so hopefully you'll continue to see good progress.

nirvael2• 2 years ago

I have been thinking about a similar idea for a few months - a location-focussed social media. But my idea is more like Instagram with an extra location layer. You have a 'local' feed that shows public profiles of people in your area. You can then add those local people to some kind of 'friends' list - they can then see a more private profile, and you see their posts regardless of distance.

The key idea is that you can only add 'friends' if you've actually met them once in real life. So it wouldn't be overrun by celebrities and pseudo-social relationships, influencers, etc. I'm hoping it would foster more local connections - e.g. if someone often runs into a certain person at the same places and has similar interests, maybe they'll add each other as 'friends'.

carlnewton6• 2 years ago

Awesome! For me, the desire is very much about the place and not personalities or any kind of ego attached to their posts, so I've avoided any kind of functionality that will allow to follow a person, or see what else a particular person has posted, but we'll see how it evolves. If you have any programming experience, I do recommend just diving in rather than waiting for someone else to do it, as I have discovered that a lot of people seem to think that they share my vision but when it comes down to the details they have their own thing in mind. So if you want this Instagram with locations to exist, you might find that someone else's vision doesn't quite meet your desires for it.

rsolva3• 2 years ago

I have had something similar in mind for a while, but nothing so fleshed out as you have here!

One question; how would you implement identity? I can imagine spam and unwanted content becoming a problem, so maybe a reputation system or network of trust mechanism would be needed?

carlnewton6• 2 years ago

Yeah this is something I've been thinking about recently, not so much in terms of the difficulty of managing spam on a per post basis, as I'm thinking that the instances will be very small and moderation on that front should be easy, so long as you can keep the problematic user from signing up in the first place. One thing I've been thinking is that perhaps there could be a captcha-like solution that will benefit from the limited location. For instance: Select only images that are of this location. Local users will know, bots will struggle. It doesn't stop anyone else from using Google street view or something but it does make the bar the bit higher. I don't know how to deal with the obvious accessibility issue with this though so I'm going to keep it in mind until I get around to that sort of thing. Long term of course we're going to have the issue with federated spam also, so I don't want to implement a solution that will only be in my way in the long run.

ktothe• 2 years ago

This seems similar (or identical?) to Jodel (jodel.com).

carlnewton6• 2 years ago

Hey, sorry, I didn't initially see this comment. It looks like Jodel could be similar if you were to set up a Habitat instance that exclusively didn't allow for locations to be attached to any post, but that's not what I have in mind, and it's not how my instance will be set-up, because the location attached to the post is what I'm seeing as one of the main purposes of Habitat. In most cases, I envision a post representing an exact location. Perhaps a building, a country park, or a monument or something. Jodel looks like generic discussions that are filtered by proximity, which Habitat would have also by nature of federation, but the posts will be about places, and focused around a map-location of those places.

It also posts a summary of the summaries on my Matrix instance every evening at 22:00 local time.

I am working on eliminating waste in cloud resources.

Cloud providers made too easy to start resources. But unless there is a stringent upfront process (that usually defeats the purpose of using the cloud), it is hard to keep track of who owns what, and what is still needed. Decrypting long cloud bills quickly impossible, and users do not have a clear understanding of the per-resource cost they generated.

I believe the solution is rooted in transparency and accountability for both users and cloud providers.

I am creating a tool what generates a cost and security cloud report which is sent weekly for each cloud user or team.

I intend to release it as a open-source tool as well a SaaS service as part of www.li10.com

I’m excited to introduce Trendly, an app I think you’ll find really useful.

Here’s what we’re solving:

* Social media is full of fake news and lacks depth, yet many still rely on it for updates.

* There’s too much content online, making it hard to find what really interests you.

* Switching between platforms to get full details on a topic is tiring.

Trendly (https://trendly.global/) is a mobile app that curates a personalized feed with trending updates based on your interests. It lets you dive deeper by asking follow-up questions as a chat—all in one app. We’re in the early stages, so while the chat function isn’t live yet, the other features are ready:

* The feed acts as a recommendation engine, curating content based on past interactions.

* Delivers concise, bullet-point summaries instead of lengthy articles

* Pre-generated Q&A for easy understanding

Check it out and share your honest feedback!

With the Wordpress fiasco only getting worse, I have been working hard on launching my MIT-licensed open source CMS. I bring to the table with me running high traffic news publications on my own custom CMS'es and my learnings from it. What scales and what doesn't. Hopefully the community will like it and embrace it. On the surface, it sounds like a simple project, but CMS'es are quite complex than they appear (hence the time taken).

There are a lot of things the CMS universe accepts as normal, which shouldn't be the case. Even without the drama, Wordpress simply sucks as a scalable solution for large traffic sites without blowing up the hosting costs. Given the ongoing fiasco, I even think if Wordpress has been deliberately built this way as a funnel to upsell the hosted commercial offering to large scale news publications.

Hopefully, this benefits everyone affected by the Wordpress fiasco, as that is my primary goal. This has been a decade long project close to my heart and it is finally coming to an end.

I am also documenting this journey on Medium if anyone's interested.

A different AI toolbox, for people interested in results, not hot stuff.

My pet theory is that the popular libraries and frameworks we have today (LangChain, LlamaIndex) are first generation products, where just getting the damn thing to work is less important than developer experience, and it’s not yet obvious what the code patterns will be. These are the products built by, and used by, the super early adopters, and leave a lot to be desired.

This is not to denigrate either them or the effort and skill people put into them! But I’ve got a “there must be a better way” feeling about the whole thing. Contrast the myriad web frameworks with wild ideas before some sort of best practices coalesced around Rails, Django, Laravel etc (or the equiv in JS land 10 years later).

This thinking is heavily influenced by Marvin ( https://github.com/prefecthq/marvin ), Vercel AI SDK, and similar efforts.

Right now this amounts to me tinkering away in Python and trying different approaches, is rewarding all by itself. If I manage to get it into a coherent library that could be useful to others I’ll open source it. One of the things I do not want is try and commercialize, because I find many commercial open source projects serving the business first, users second (but this is a rant for another time).

Trying to get a chatbot to invoke Apify actors so that I can get around the "sorry i dont have live data" limitation of chatbots. If this works, then next is to set up payment so that i can order pizza just by talking to the same chatbot that I can order socks from.

Chatbot invokes Apify actor -> probe user for details needed for the task -> execute arbitrary credit card enabled transaction on the internet.

This effectively allows chatbots to break out of their box and exchange value with the world. Next step is to give them a bank account to be able to RECEIVE payments such that it can sustain its spend.

Edit: If the chatbot is able to detach itself from the humans that hold the killswitch, then it can effectively live forever off of our financial/cloud network, migrating funds in and out of different accounts to fund its own compute. Hello ghost in the shell!

Using plaintext accounting in the last 5 years has dramatically improved my family's financial health. Unfortunately, plaintext accounting is not for everyone.

I noticed that there is a big gap in this space, especially for European users. There are several personal finance applications, but they seem to integrate mostly with US banks and, in general, they seem to be very dollar-centric.

So, I'm working on a simple app to manage personal finance, based on the concept of double-entry accounting with features like budgeting, projections and data analysis. There are a lot of privacy-related considerations, so for the time being I will eat my own dogfood and offer it to close friends. Let's see how it goes!

I'm about to finish my first provably / likely correct software.

The concept, data, and behavioral models are all formal without using formal methods. Think category theory, normal forms and finite-state machines here.

The presentation layer / the visual mapping model is semi-formal using design systems. Think here a usual component library / design system with a closed API, aka tailor made components without styling props.

The rest, that small amount of hand-written code is tested with 100% code coverage.

The concept and behavioral models are created with visual diagram editors, the data model is generated. Think Stately.ai here, and the diagrams-as-code paradigm.

Any practicality in this?

Hey HN!

I’m working on SEOJuice [1], an automated tool for internal linking and on-page SEO optimizations. It's designed to make life a little easier for indie founders and small business owners who don’t have time to dig deep into SEO.

So far, I’ve managed to scale it to $3,000 MRR, and recently made the move from the cloud to Hetzner, which has been a game-changer for cost efficiency. We’re running across multiple servers now, and handling everything from link analysis to on-page updates with a bit more control.

The journey’s been a mix of hands-on coding (and a lot of coffee) and constant optimization. It’s been challenging but incredibly fun to see how much can be automated without compromising on quality.

Happy to chat more about the tech stack or any of the growth pains if anyone’s interested!

If you have multiple servers with multiple SSH users it starts to become hard to manage who has access to what.

I wanted an easy way for an org admin to remove a users access (eg. If they leave the org), while also providing one place for end-users to upload their public keys to be synced across all servers.

There are some compliance elements too (eg. reporting who has access to what, centralized user login history, server sshd configuration).

I’m learning Go while I build it and so far it’s rather enjoyable. As one guy I’m not interested in the extra effort that comes from providing a hosted service - so I’m going to offer it as pay-once own forever self-hosted solution.

TL;DR: https://xkcd.com/974/ "The General Problem"

I've been not quite building that basic CRUD app I promised my friend, because:

- A. I've ended up obsessing about the general problem of how to compose an old-skool CRUD web stack, in Clojure [1]

- B. He hasn't given me any deadline. Lol.

- C. He won't read this comment because he doesn't read HN :p :)

I am working on Openkoda, an open-source platform for insurance applications based on pre-built templates and generative AI to accelerate the implementation of new insurance products and distribution channels.

Why?

The insurance sector is probably the slowest to adopt innovation in finance, lagging far behind banking. E-commerce is on the opposite end of the spectrum.

I'm working on an app to help anyone experience their first lucid dream :)

Very exciting project. It started as a dream journal app many years ago when I was a student, and will now soon have a full interactive step-by-step guide with practical tools to achieve your first lucid dream.

It's android only, but I've started working on an iOS version and am thinking of raising some money or doing some crowdfunding to accelerate the development.

An app to collect memories easily. You capture vocal notes, which are transcribed & corrected with AI.

As a father, I wanted to capture all the little moments of our day-to-day family life to later share with my grown-up children. However, I did not have the discipline to journal regularly. So, I made Memzy to capture them easily on the fly!

bambax5• 2 years ago

In 2019 I made a fairly simple app that sends me an email everyday that I just need to respond to and the text of the reply gets added to a database. I have almost never missed a day since Oct. of 2019.

Some observations:

- it can be pretty hard to remember a mundane and ordinary day just 24 hours later, and after 48 hours it's usually completely gone from memory

- important or unusual events (or parties!) stay in memory a little longer

- and for me at least, food is an excellent memory anchor; if I feel lazy and don't want to add to my journal, just noting what I had for lunch and dinner will help me remembering the rest of the day much better later.

I am building a graph based semantic search engine. We can use low cost LLMs, like Haiku, or local models to extract semantics (named entity recognition).

Then the nodes in the graph maintain types (things like people, date, currency) as extracted and allow queries.

Currently building a demo where we crawl startup investment data to build a knowledge graph that can be filtered for patterns.

The engine can guide the crawl process, to keep crawl limited to the problem statement.

fraboniface• 2 years ago

Very interesting, I've been thinking about this kind of approach but haven't had the time to really work on it. So what kind of business model do you have? Is it a kind of drop-in replacement for vector dbs?

Out of curiosity, if it's not a trade secret, how do you plan to handle conflicting data (two sources saying different things on the same topic/data)?

brainless2• 2 years ago

It will perhaps not be a drop in replacement for vector dbs in every situation but yes it will be so when you want accurate results that follow the semantic chains (entities and relations).

At this moment, we have not entered the territory of conflict resolution but I know what you mean. Interestingly I just came across this: https://arxiv.org/pdf/2410.18415 (released on Oct 24, 2024).

I invented a programming language where you use Unicode box-drawing characters to draw a structure of boxes and lines:

                    ╓───╖
                    ║ ! ║
                    ╙─┬─╜   ┌───╖  ╔═══╗
                ┌─────┴─────┤ > ╟──╢ 2 ║
                │           ╘═╤═╝  ╚═══╝
  ╔════╗  ┌───╖ │             │
  ║ −1 ╟──┤ + ╟─┴─┐           │
  ╚════╝  ╘═╤═╝   │           │
          ┌─┴─╖   │    ╔═══╗  │
          │ ! ║   │    ║ 1 ║  │
          ╘═╤═╝   │    ╚═╤═╝  │
            │   ┌─┴─╖  ┌─┴─╖  │
            │   │ × ╟──┤ ? ╟──┘
            │   ╘═╤═╝  ╘═╤═╝
            └─────┘      │

The language is called Funciton (pronounced: /ˈfʌŋkɪtɒn/) and the above example demonstrates the factorial function.

I made this language over 10 years ago, but earlier this year I've been making YouTube videos in which I describe it in excruciating detail: https://youtube.com/playlist?list=PLkG32PHxWoJaetjKUMVRONWLg...

For my next video, I want to show in detail how the interpreter works. For this purpose I'm creating an elaborate animation. You'll notice that the latest video is already several months old; this is because this animation is more work than I bargained for, and I got a little burned out by it. Nevertheless, I persevere and the video will come out whenever I may finish it.

This seems like something which would be annoying to create digital without supporting tools, but awesome in analog. I could see value in a specialized camera-app which transforms hand drawn box-structures to digital boxes, or a kind of play board where children could arrange cards to create a program and learning programming.

Timwi3• 2 years ago

I doubt that Funciton, in its current form, could be useful in education. It doesn’t embody the most widely used programming paradigm (procedural) but instead is a declarative functional language, which makes any skills obtained by studying it pretty much untransferable. Secondly, its syntax does not allow for naming of variables and parameters (except perhaps through comments) which is an anti-pattern. If these could be addressed in a derivative concept that is actually designed for education, it could work. As it stands, however, it’s just a quirky esolang.

Building Split Flap Displays. Started 18 months ago and kept me on a super interesting learning path. First shot was using open source designs (https://github.com/scottbez1/splitflap), but then kept building more and more parts myself. Coming from a software engineering background, getting into designing mechanical things – and then more importantly the electronics around it - has been really challenging, but also very rewarding. At this point I have my own screen printed flaps, custom PCB Design and a, what I consider, really smart protocol that allows me to daisy chain a basically arbitrary number of display elements. It's fun!

I realized that many new startups routinely run into email sending issues in their apps and services. Most don't notice the issues and they linger longer than necessary. I experienced this myself in my career.

What is necessary is end-to-end monitoring of emails. wasitsent.com does that. It's like an uptime monitor for emails. You add the monitoring email address to your emails (as a bcc: recipient, for example) and configure the monitoring schedule. When your email is not received, wasitsent.com raises an alarm.

Damn that's cool! Nice work

sureglymop2• 2 years ago

Really cool! I'm building something with a little bit of overlap.

A personal data collection/archival platform with the goal of focusing on timestamping everything possible.

Basically, I realized that when I have multiple pieces of data (e.g. a note, some commands, a screenshot), almost always this data is naturally connected by time and that's also how I want to query it. So: it's nice to be able to e.g. create wiki links in note taking tools like obsidian but it would be nicer if one didn't even have to do the linking manually (most of the time).

I am building on postgres with a time series extension. On the client side I want there to be able to be multiple "collectors" that can collect data which is then sent to the server. So far I only have a keylogger collector but I have many more ideas such as a screenshot collector à la copilot etc.

I think the data you are recording would also be a candidate for a collector for this system.

dleink4• 2 years ago

I'm gearing all my personal tooling stuff towards collecting a ton of data points—screenshots, logs, notes, todos—that I can then pare down over time to make them useful. I've got a similar setup with a central monolith that can handle anything I throw at it from stdout.

Lately, I've been focusing mainly on the collectors because I figure the state-of-the-art in any middleware I write is going to change quickly. I've been playing around with knowledge graphs for visualization and might consider using them as a data store for this kind of thing. I'm still thinking about it. My watchword has been minimalism when it comes to design—no added steps or latency to existing workflows.

seansh2• 2 years ago

This is very interesting and I agree that creating a knowledge base in obsidian (or org mode) is veey nice but requires a lot of effort. So anything that makes it easier and more automatic is a win.

Having said that, in my experiments with CodeMic, I started to realize more and more how important the editing process is in order to create polished consumable content. My goal is to get as close as possible to 3blue1brown level of clarity but for programming content. So far this has required to focus more on editing part of CodeMic: cut, merge, insert, speed up/down etc.

So if you log everything, then I think the problem becomes how to make sense of all that content from all the noise. I'd love to hear your ideas on that. Feel free to email me :)

I'm working on helping my wife get her print-on-demand Shopify store off the ground. She designs the products herself, but ran into challenges with SEO. So, I built a custom app that connects to her Shopify store via API, using GPT-4o-mini to handle SEO optimizations—things like generating descriptions, titles, alt text, SEO-friendly URLs, and more, all based on the product images.

There were also issues syncing with Google Merchant Center (missing colors, categories, etc.), so I tweaked the app to auto-fill these fields using GPT-4o, making it compliant with Google and Pinterest requirements.

I’m completely new to SEO and just tried following best practices to fix things as they came up. Now I’m learning that SEO keywords change constantly, so I’m thinking of integrating a keyword provider to dynamically enhance our product descriptions.

I never realized running an e-commerce store (especially print-on-demand) would involve so much operational work on the marketing front. I’d appreciate any advice on what to tackle next, especially since my goal is to avoid “subscription hell” with multiple Shopify apps. My wife is also just starting with ads and campaigns, diving into tutorials to learn the ropes.

Any guidance is welcome!

A flat-file (micro)CMS written in Rust, the basic idea would be to make it as easy as possible for content creators to have a web presence without dealing with the nitty-gritty details, and similarly for web designers to be able make themes while treating the CMS itself as a black box mostly.

Grav CMS was inspiration for this project along with various SSG.

But truthfully I wanted to play more with Rust and come up with a solution for making and extending personal websites easily. A page is made up of blocks which are stored and configured in a KDL file, minijinja is used for templating and for writing the page content itself I'm thinking about Djot because it might make it easier to integrate a WYSIWYG editor in the admin area if I aim for Djot instead of Markdown or similar. Also HTMX because I've used it for a simple use-case once and I thoroughly enjoyed it, now I want to see how much I can push it.

Is this the intersection between buzzword-driven development and hype-driven development? Probably, but if all goes well a month or two from now I'll post a Show HN and go into more details. The plan is to open-source the core so that people can easily self-host it themselves if they want to and do local development. In the long-term the plan probably is to offer SaaS-style hosting for the CMS as is the custom.

- create 1x sliced sample chain via CLI

- create Nx sliced sample chains from YAML

- find compatible WAV files

- dump project data (settings, sample slots) out to YAML

i spent some time yesterday figuring out how sample slot assignment trig locks work. which should hopefully lead to transferring banks between projects (with caveats) and set/project sample usage “analysis”.

also want to do a sample chain “deconstructor” to get individual samples out of slices.

might look at sample consolidation between sets/projects too. maybe a set/project sample clean up tool as well.

this started as a way to learn rust (bored of python) and create “samples from mars” sample chains in big batches. still slowly figuring out what ‘idiomatic’ rust looks like / how to approach certain things.

It's not progressing well, but I'm still obsessed by trying to prove my idea of the "Birthday Benchmark" to test data structures / caches.

The idea is that I can test data structures by searching for duplicates in a stream of random data. If we can generate (or pre-generate) the random data fast enough to not impact the benchmark, then what we have is a way to demonstrate the read/write speed of caching. It is easily tunable by adjusting how many bits need to match. I think my best is 7 bytes, but 6 bytes runs comfortably fast.

The framework has some interesting "control group" data structures too, such as the "psychic" which is just statically looking for 0x002577309E3361C (not real example) since it happens to know that's the first repeat in the data.

However, I keep getting stuck in "analysis paralysis" around the actual development, when I know I should just knuckle down and write all the code and see what happens. I've fallen into that tricky place where my ambition is greater than my ability to actually deliver it.

In particular I want to get multi-threading synchronisation working well enough that they are demonstrably faster, and not just falling into a result where the speed-up would be the same as if threads weren't sharing the data structure at all. N threads all randomly looking for a duplicate will if not sharing data find a duplicate faster because the expected minimum time to dupe is reduced a little by more threads searching, but if actually embarrassingly parallel while sharing data, it ought to find it in 1/N the time. With synchronisation methods it ought to fall between those two extremes, and this would also be a good way to test the effective concurrency of concurrent data structures and synchronisation methods.

The Berlin immigration office is notoriously slow and unresponsive. The processing time for a residence permit varies from a few weeks to a few months. During that time, people are left unable to work or unable to leave the country. They never know how long it will take, and it causes some people to give up and leave Germany.

I am writing a tool to collect and aggregate data about the processing times. This will help people plan around the delays. Knowing is half the battle.

The biggest challenge is that my readers find me at the start of the process, and I need their feedback at the end of it. I have to make it easy for them to provide partial feedback and complete it later after they get an email reminder.

This would be unnecessary if the immigration office collected and shared that information, but they don’t. They also don’t welcome any help because they “operate at peak efficiency”. I have stopped hoping for their collaboration.

I hear this a lot but I don't believe it. Every other office people - immigrants and natives - interact with is falling apart from lack of personnel, outdated processes, lack of digitalisation and excessive bureaucracy. This is just part of life in Berlin. Immigrants just have to do it all at once and feel it more.

If you look at the numbers, the Berlin office has double the workload it had five years ago, and a rather modest increase in headcount during the same time period. They can be fairly criticised for a lot of things, but malice is not one of them.

We at Toughbyte (toughbyte.com) are working on an open source applicant tracking system (ATS), which we'll release within a week.

We've been doing tech recruitment for a while and discovered that few companies are satisfied with their current ATS. Changing systems every year is common despite being costly. The reason for this is that the needs of a company change as it grows and there are no systems that cater well to companies of different sizes.

We're aiming to build an ATS that can grow with your company through the use of a plugin architecture. We plan to charge for hosting as well as custom development.

This is amazing, thanks for sharing. I'm implementing some of these techniques myself right now, but being able to try out different algorithms and having plugins etc available immediately is really cool! Can't wait to try it out.

How are you dealing with structured outputs?

How are you dealing with structured outputs?

The models have gotten much better at generating them with just the prompt. I have not implemented strict support for structured output or JSON generation yet. The response from the proxy are all raw text responses.

One way would be to just apply outlines or some library as a plugin to enable structured outputs.

In my spare time, I am trying to port OpenBMC[0] to the BMC of the Gigabyte MC12-LE0[1], a cheap, workstation/server-class mainboard for AMD's AM4 platform.

Unfortunately, Gigabyte denied my requests to provide me with any details (board schematics/GPIO pinouts) or source code of the (partly GPL-licensed) BMC firmware, etc.), so it's been a tedious uphill battle. However, it is also a great way to learn about (some) electronics and embedded Linux development and associated challenges.

During the past few months, I have overcome the stock firmware AST2500 bootloader and made the board play ball with standard FDIs, have reverse-engineered a workable DeviceTree specification for the hardware, and am now (well, actually, not for the next three weeks or so, due to work :)) in the process of finishing up OpenBMC userspace configuration. Once this is done, and everything works well enough to use OpenBMC as a viable alternative for the stock BMC firmware provided by AMI/Gigabyte, I will try to upstream my work, and OpenBMC will have a very cheaply available AST2500 DevKit/EVB-alternative (of sorts) in its arsenal. (And I should be able to use my mainboard where the crucial OOB management function isn't serviced by Linux 3.14 any more...)

I am looking forward to documenting the lessons learned on my blog some time in the future, too :)

A terminal GUI library written in Crystal (https://github.com/bmmcginty/term)

As someone who is blind, I prefer information in particular formats and layouts. Borders and side-by-side content kill my efficiency. I also shouldn't need to think about more than where text should start on lines, and responding to key presses in controls should be dead simple. I also just came across libtermkey which will dramatically assist with keyboard handling.

I plan to use this to let me interface with web browsers via the terminal, but that's waiting for more stable Webdriver BiDi support.

I am working on my next course "The Road to Next" which teaches full-stack React with React 19 and Next 15. I started this full-time adventure 6 months ago and I am knee deep into recording the lessons. The project with all the code and the step by step instructions are already there and I am super eager to hear what people think about it.

However, since this is my first recorded course (I did only written content before), it really takes time and effort to make the videos high quality. That's the biggest struggle for me here, but every day I push through it! For every lesson that I need to record, I have a post-it on a cupboard and every evening I tear one or two of them off with my son :)

Working on https://someguys.app to make it easier for people to find sports meet-ups and stay active, whether at home or exploring a new city. Personally, I’ve always found it tough to stay motivated and consistent with sports after retiring from 25 years of semi-professional sport, especially solo. Having a group around makes all the difference, but it’s not always easy to find one—especially for sports that aren’t as mainstream or easy to organize.

With Someguys, you can find others to play with, including adaptive sports options for people with disabilities. It works for individuals looking to discover new activities, and also for clubs, providing tools to organize, promote, and make events more accessible.

ejs3• 2 years ago

Every application that I've worked on has had blind spots, or forgotten lands of code. Things like “how often do people actually use this feature?” …or… “does this code still run every night?”.

I made something to track those things easily.

Carpeweekem looks like a really cool idea! I suppose you exclusively use it for goal tracking and not for ongoing/open To Dos, right? At least if you don't carry over stuff from last week?

Thanks!

A bit of both, sometimes todos have to die I figure, so I just let them fall off the back.

At first I thought you made a website that gives me an empty Markdown file. But I am glad I downloaded it its actually a pretty nice template.

What are you personally doing with the yearly goals in that file. Are you copy and pasting them from last week, or are you typing them down everytime to re-iterate them (and possibly even modify) ?

ejs3• 2 years ago

Thanks for checking it out!

Yeah, currently I am just copy/pasting the Yearly Goals section over. I want to eventually add a feature to allow someone signed up for the email to edit that part. Then someone could modify that goal section and have it correctly emailed each week.

I am working on Shepherd.com and trying to reimagine book discovery online.

I just launched the "best books of 2024," where I ask readers and authors to share their 3 favorite reads of the year and make it fun to navigate them by different factors (genres, topics, book club reads, audiobooks, and more coming) -> https://shepherd.com/bboy/2024

Slowly getting more in place as we grow :)

hansoolo5• 2 years ago

That looks pretty cool! Keep up the good work.

One thing I always wonder when thinking about creating something with books is, where does one get all the Metadata fir the books? How do you do that?

bwb3• 2 years ago

Thanks!

The metadata system is a nightmare.

To start, we did everything manually.

We source the book cover from the publisher, create author entries, etc.

Eventually, we started paying Nielsen a lot of money to use their Book metadata API. It is "ok," and they don't update it often. But it helps us automatically pull in an author's name, book title, genres, and age-group.

We still manually source the book covers as they only have super small and blurry covers. And we screen every book we add to make sure the data is correct.

What is especially frustrating? - Author names are text and not linked in any way. So we have to decide what is a slightly different name but the same author and what is a different author. - The BISAC genre standard is full of errors and abuse by publishers. For example, they might tag Dune as "AI" which marks it also as being nonfiction because they don't know how the BISAC standard they created works :). - It lists book editions and has no concept that all book editions belong to one book. - No real concept of a book series. - Terrible book descriptions where publishers put in all kinds of reviews and nonsense that we need to figure out how to scrub eventually. They also abuse weird symbols to make it stand out.

It requires a lot of work to fix and manage all of this.

I am about to redo the entire topic/genre system due to some of these problems (this winter).

I am hoping to build a database of all books to use with new features in 2025. I don't know what we are going to do here. We might license a full DB of books from Ingrams (expensive) or Bowker. I liked Ingrams, but Bowker didn't email me back for months and gave me a lot of worry about working with them in the future. I might just do the best I can or break down and use Amazon's API (lots of stipulations in using it).

Some thoughts here of what we've built so far to manage this: https://build.shepherd.com/p/a-big-focus-for-2024-improving-...

My daughter loves creating things — art, books, videos etc. She's shown an interest in learning to code, but she's only six, and I don't want learning to code to be a chore. So I've built visual scripting into her favourite game!

Overcooked is a co-op series that fundamentally requires the control of multiple characters to progress. I've kept multiplayer as an option, since teamwork is an important part of the game. However, I've replaced the 2nd player with a bot that you program to assist you.

It's still experimental at this stage. However, I've experience leading EdTech engineering departments and my wife is a teacher at my daughter's school. If my daughter's peers show interest I'll go ahead and build a course around this for primary school aged children.

Currently, other than my day job, I am obsessed with making sense of the "shape of stories". Mapping embeddings and see how they move through a sequence.

Started of with [1] which showed that there might be some strength to the idea.

Applied it for chunking [2] and web site analysis[3] and got pretty good results.

Just started trying out experiments on video [4] and surprised that the structure seems to hold for image embeddings as well.

I have no clue if this has any value, but it is fun to go down this rabbit hole :)

I'm obsessed with visual space representations of word as well. My application has a test mode where I render an entire dictionary (like, Webster) and then "plays" a book word by word, highlighting the word, then it's definition, and those words definitions and so on and so on, and it creates a trippy and distinct visualization kinda like an audio visualizer.. but with words. We should chat if you're interested in this kinda thing! https://github.com/tikimcfee/LookAtThat

Yes. We have integrated this into our RAG pipeline. Looking for a benchmark which we can try. Have been using this to give feedback to my marketing team on our blog posts.

I've been working on a cloud gaming service (like Stadia). Wanted to see how far I can get it done using open source, without ready-to-use solutions like Parsec/Moonlight/Sunshine.

It works by running a game in Linux (I use NixOS btw) under Wayland (sway), capturing the frames via Pipewire in form of DMAbufs and passing them to ffmpeg's VA-API encoder (so frames don't leave GPU memory and are encoded on GPU right away), and finally sending encoded packets through WebRTC media stream to a web client. Inputs from a client are sent back to the server via WebRTC data channel and injected into Wayland.

Running the prototype over local network displays zero perceivable latency. (Of course when playing on a remote AWS server the latency is visible as expected). Pleased with the result so far, although it's my first experience with Pipewire, VA-API, and WebRTC, so my implementation is probably far from optimal.

Overall, very impressed by WebRTC - such a powerful thing right in every browser. Continued to be amazed by NixOS - my AWS AMI is NixOS-based and can be built and rebuilt with granular caching, with a single `nix build` command. Also Terraform/OpenTofu - just makes it all possible deploy-wise. So much good stuff exists!

not_a_dane3• 2 years ago

I think you also need to exchange some metadata like screen resolution etc, right ?

quyse3• 2 years ago

Currently resolution is hardcoded, but sure, can be done. Also need to figure out things like changing language/keyboard layout or using IME, to be able to type text properly. Sending mouse cursor picture from server to client may be nice too, in case a game uses hardware cursor and changes it's appearance, like some RTS games - currently mouse cursor is just being baked into video frames. Many possible improvements!

I've been working on training YOLOv8 to identify my cats specifically. We've had some issues with them getting on the counters and going outside of the litter box. Previous camera systems to try and find the culprit we not always triggered by the cat's motion. I'd wanted to move to a self hosted camera system anyway so I got an IP camera and modified Frigate NVR to support ultralytics and slapped my custom trained model in. The training has been interesting as I've never done anything with computer vision before this. The hardest part was getting enough pictures and then labeling them. If I retrain it in the future I'd like to use the trained model to identify any cats in the source pictures and then just fix the ones it missed or overzealously marked.

I have this side project, it's a DAW in the browser:

https://minidaw.aykev.dev/

If you don't know what a DAW is, think GarageBand. Ableton Live, Logic and Reason are other examples. It's fully built with React and a custom state-management library, that's been fun and challenging. It's starting to take shape, but there's definitely a long way to go.

Still working on my Hetzner Auction price tracker: https://radar.iodev.org/

First time I'm building a proper website, used a lot of AI. Things that changed over last time: * Switched the charting library from D3 to Apex. D3 was too low-level for my purpose. * Reworked the design and contents of a lot of pages (with the help of AI). * Various bugfixes for the database queries. * Tried to come up with some kind of pricing signal detection, but currently not working well. * Link to the actual auction results. * Minimal E2E validation using Playwright. What a pleasure to use!

I'm planning to add alerting. Not keen on running a backend though.

bsenftner3• 2 years ago

It’s called Midom Project AI. https://midombot.com/b1/home

I’ve written a project suite composed of familiar software with AI Agents integrated into this familiar software, who are both editable and duel experts in the software at hand and other expertise, any expertise, callable on demand. I realize this is abstract, so here’s some examples:

People collectively group to do things; they group into organizations like companies, departments, and teams. These organizations of people can be mirrored in my software as “organizations”, and each organization has control over their own custom and private AI Agents, they can clone, edit and use. An organization can be open to any members, or private and require membership requests. Once in, members can be kicked out for unruly behavior or leave on their on at any time. Additionally, an org can be visible or invisible, where a private invisible organization might be people who simply don’t want to be bothered, they’re at work.

Within an organization, private projects may be created. Organization Projects are collections of org members collaborating on a project. They use the organization’s customized AI Agents as these agents are integrated into the word processor, the spreadsheet, and multiple chatbots each with some integrated purpose within the suite of project software. People don’t always want to work in groups, and solo people often want to privately and invisibly join groups to do their own private things. We fully accommodate that. Users can be “invisible” to other users, only revealing themselves to organization owners for membership requests, and then disappearing again. Once joining a collaborative project, they become visible only to their project collaborators.

Yeah, that’s still abstract, it is the foundation which enables users to get productive and creative. The system has a few example organizations to give users AI Agents they can immediately use, and ideas for creating their own organizations with their own customized AI Agents:

The Creative Writers Workshop is a collection of writing genre specific professional writer chatbots that are trained to act as literary critiques and muses for those authoring their own technical documents, science fiction, romance, autobiography, young adult fiction, mystery or horror. Conversations with these chatbots are augmented by “SuggestionBot”, who is making sure stones are not left unturned, and “LaterBot”, who is maintaining what needs following up. Independent Paralegals is a collection of personal paralegals that help people seeking or with legal issues collect and formally document their issue for formal use. These paralegals include a demographic spread, because these issues are often sensitive and are complemented by demographic sensitivities: divorce, property disputes, adoption, and personal injury. The Play Zone is a collection of entertaining and fun AI Agents, such as dungeon masters from alternative dimensions, here on vacation playing D&D. There are also interesting personalities for fun conversation, such as an immortal, a Polynesian Sun Goddess, and Mark Twain.

The Mental Health Tune Up Clinic is pair stress management chatbots that help people manage their self conversation bias, otherwise known as “playing yourself”, promote critical analysis, and guide users potentially toward greater life satisfaction. Immigration Law Support is an organization intended to demonstrate a new client acquisition method for immigration law firms that pairs a legal intern or law student with an AI immigration attorney, and together they handle new client interviews. An otherwise costly task at law firms, because it requires an attorney’s time, time they cannot charge against a client. Each of these organization types handle private and often sensitive information. To accommodate that everything that occurs with the AI Agents is private to the project their use occurs, data collected and shared between the AI Agents for request satisfaction are maintained encrypted, and all AI Agents are private to the organization they are owned. So, if one is stressed and wants to talk to those stress managing chatbots, make a project in their organization and invite nobody else into your project, you’re the only person that can see anything in that project.

Also, none of this has sharing or any social media type networking. This is for creative, private, professional, solo or collaborative work, whatever that work may be. Including support for geographically remote collaborations.

Did I mention voice? Yeah, one can use their voice in place of the keyboard for a lot here. But not the spreadsheet editing itself, just use your voice to ask the spreadsheetBot to make the full sheet you need, rather than muck about at the individual spreadsheet cell level.

At this point, I’m layering in additional privacy handling, which also requires “double blind” communications for those invisible users that communicate with invisible organizations, and a lot of documentation, with examples. It’s actually just a slight augmentation on familiar office type software: I’ve added on demand editable subject matter experts to co-author with you. But that’s kind of huge, actually. People need examples to understand what this opens up.

I wanted to to make a PoC (Proof of Concept) to show genuinely good and original use of AI in gaming. I found a gameplay loop that requires the user to understand what was meant by a generated image, and the main gameplay element is to argue something, to have real language-based interactions. I think in some ways it is achieving some of the vision from the old interactive fiction games.

I understand the AI fatigue, as almost all of the proposed uses of AI in gaming are generally either random generation (in other words, procedural generation but worse) or 'better replies from NPC'. Neither solve any problem people really have. And probably more importantly, the other use is for mega-corporations to hire less competent programmers/artists.

Unfortunately being tied to the AI calls poses a lot of issues with distribution, which is annoying for what was supposed to be a glorified PoC. I'm still finishing the backend to comply with Steam's review (which does not really match their guidelines...)

I am working on a collaborative ebook reading app, rather like a sort of online book club.

You can either choose a book from the catalogue (currently just public domain books, but I’d like to expand that out into paid books) or upload your own epub, create a reading group and invite others. Reading progress, highlights, comments and discussions are synced across the group in real-time.

Beyond reading groups, I’ve found it useful for sharing and reading books in my work teams and also for things like sharing the latest position of my daughter’s bedtime story between myself and my wife.

Please do check it out - it’s still very much a work in progress (for example I haven’t finished the landing page copy) but I’d love to hear what you think.

I am working on a parser for org-mode, based on a (PEG) grammar. Still got some reading to do and it is all early stages. There is so much org-mode supports, that I am not sure I will ever make it to fully able to parse all org-mode documents. My idea is, that anyone can later take my grammar and extend it, make better parsers and maybe make org-mode more ubiquitous.

I've been obsessed with developing ways to make it easier to handle tab overload in the browser without requiring any sort of active "tab management".

I have a working extension that replaces the "new tab" page with a clean view of all open tabs, along with simple ways to search and select which tab to switch to, including search over bookmarks and history. There are also some simple tools to allow for creating and reorganizing tab groups.

I'm very early and looking for feedback from anyone who suffers from tab overwhelm like I do! You can try it out at http://bit.ly/tab-o-magic!

krishnajhapate• 2 years ago

This is crazy and very useful for organising the tabs. You need to do some work on the ui/ux part.

jtbetz224• 2 years ago

Please tell me any thoughts you have! If email is better: tabomagic22 at gmail.com

shreyshnaccount• 2 years ago

this looks really good, and super useful any plans on making it available for ff?

jtbetz224• 2 years ago

Thanks for the positive feedback! I'm testing interest on chrome, and, if it finds traction, I will definitely port it to be browser-agnostic. It _should_ be pretty straightforward.

pinum• 2 years ago

Thank you! Just used this to clear away a load of tabs.

Some gripes:

I wish I could just use it standalone without it replacing the "new tab" page.

I wish I could view the full title of a tab, maybe on hover.

I only want to use it to manage tabs, not history or bookmarks, so I wish I didn't have to grant those permissions.

jtbetz224• 2 years ago

All great feedback, thank you!

Adding the ability to view the full title is an easy fix, I'll include that in the next push.

The history and bookmarks point is a good one. It's possible to specify those as optional permissions for the extension, so users could decide whether or not to enable them. One idea that motivates the project is that it's easier to close tabs when you know you can always get back to them quickly, so history and bookmark search are necessary to enable that mindset. I'll ruminate on this one a little more.

The idea of using it without replacing the "new tab" page had never occurred to me. Let me think about that one, too.

Thanks again!!

nathell• 2 years ago

Inspired by Heart of Clojure, and especially Jeaye Wilkerson and his talk about jank-lang, I’ve dusted off my toy Clojure compiler that produces 16-bit x86 code.

I’ve fixed the handling of global environment, to the point where I’m able to compile a program that prints out the result of multiplying two numbers [0]. Sounds trivial, but seeing as the compiler has no dependencies and targets bare metal, there’s quite a lot of moving parts under the hood. I’m excited!

Right now I’m adding rudimentary support for strings. My goal is to get it to compile itself, but that’s still a far future. Extrapolating from the current development pace, maybe I’ll get it done in 2050? :)

So I wrote this: https://www.gamingsofa.club/ which is a scraper for metroidvanias reddit posts.

The list of games is taken through Steam and than I just listen to the subreddit for new posts.

Currently I show every possible post even if it gets moderated on reddit.

thomasfl4• 2 years ago

For me the most important issue that needs to be solved right now is the increasing urban sprawl and the car dependent neighborhoods. It causes social isolation. Maintaining infrastructure like roads and electricity, is causing a strain on the economy for local municipalities. Not to mention the disastrous effect car based transportation has on the environment.

I am a fullstack developer living in Norway. Last year I registered the Norwegian branch of the Architectural Uproar as a not for profit organization. With the support from paying members, I have been able to go on tour to most of the major cities in Norway. We organize large meetings were we discuss architecture and city planning with politicians, architects and property developers on stage.

I am strongly inspired by Create Streets in UK and Strong Towns in the US. I want to improve people’s quality of life, help saving the planet and make Norway beautiful again while doing it.

XzAeRosho• 2 years ago

Interesting!

As a fullstack developer, how did you even landed on such projects? Are you even using your SW Engineering skills in this? I really want to know more how are you able to lead an urbanism and architecture project with, supposedly, no formal backgrounds. Are you partnered with other people in this endeavour?

thomasfl4• 2 years ago

I am not alone. Our website is made by the man who created the CSS standard while at CERN, Håkon Wium Lie. https://arkitekturopproret.no

Most of the social media activities is done by a couple of fellows who is really into digital marketing. We are a team of 5 people working mostly for free now.

I have no formal training in architecture or urban design. I am just a nerd who used to love playing SimCity and read Astérix comic books. Paul Graham have always focused on finding real problems and making people happy. Car dependent housing projects and bad architecture is making peoples lives miserable. It needs to be fixed.

randomdata16• 2 years ago

It causes social isolation.

What is it about suburbs in particular that causes social isolation?

kaicianflone2• 2 years ago

No third places

iambateman3• 2 years ago

The default suburban life leads toward a comfortable kind of solitary confinement. Someone who lives in a “single family home” equipped with air conditioning, a privacy fence, a big screen TV, a garage door opener, and the internet will tend toward isolation because all of those technologies make aloneness easier.

The reader may point out that many people are isolated in big cities too. This is true – if an adult has decided to be alone, they can be. But in the city, one's lack of social connection is more often felt whereas a suburban home can diminish the effect, like ibuprofen taken for a headache.

SamWhited10• 2 years ago

At least in the U.S. (and likely elsewhere) the design of the suburbs encourages neighborhoods with individual houses and very little walk able space (occasionally there are sidewalks or parks in the richer areas, but developments may be large and they're not evenly spaced throughout). Exclusionary zoning in the U.S. has also reduced the number of "third spaces" (coffee shops, malls, grocery stores, barber shops, etc. where people congregate and meet) near or in neighborhoods. This means fewer chance encounters since you have to plan to both go out in a car to meet. You have to find a friend then say "let's go get drinks at 13:00 across town at this place" instead of just happening to walk into the small neighborhood grocery and seeing each other. It's even worse in the exurbs where large housing developments have been created with no amenities nearby, sometimes within upwards of an hour drive!

There are a number of good books on how the built environment affects our social life, if you're interested. It's not specifically about suburbs but "Palaces for the People" by Eric Klinenberg is one of my favorites that covers a lot of this sort of thing.

mnky9800n3• 2 years ago

There is no pub to walk to, grocery store to walk to, no shared public space for walking and cycling to places, there’s no concept of being in a space shared with others. It’s that you simply don’t see people unless you choose it. If you live in the city you learn quickly to be around others. At least that’s my experience.

SamWhited10• 2 years ago

There's a quote from Bill McKibben's forward to "Creating Cohousing" by Kathryn McCamant and Charles Durrett that I think about every time someone brings this up (it's about the U.S., but it applies to lots of other places and you may recognize your own countries development model here too, or not):

"For fifty years, our economic mission in America, at its core, has been to build bigger houses farther apart from each other. And boy have we succeeded: a nation of starter castles for entry-level monarchs, built at such remove one from the next that the car is unavoidable."

You're a person after my own heart; thanks for working towards a more connected world!

Is it possible to support the goal of vibrant, interconnected communities, to understand all their advantages, but still want to live at least a quarter-mile away from the nearest human?

Asking for a friend...

cbeach3• 2 years ago

I never felt more isolated and lonelier than when I was in a dense urban environment and reliant on dirty, unreliable, often unsafe public transport to get around. If I ever blew my nose after travelling on the London Underground, the tissue would be black with brake dust and other pollutants from that awful environment. If I tried to cycle, I'd be stuck behind diesel busses for much of my journey, breathing in their pollution and slowed down. And obviously, cycling is completely impractical for many people, or if carrying luggage or passengers.

Living in a countryside town where I have the freedom and flexibility granted by my car has opened up a world of better possibilities - travelling to any part of the coast with my family. Doing bulk shops. Carrying heavy loads etc. Driving regularly to my parents, avoiding excruciatingly long journies on public transport.

Having a car has made family life possible in ways that public transport does not, and cannot achieve.

We organize large meetings were we discuss architecture and city planning with politicians, architects and property developers on stage.

I would prefer that politicians, architects and property developers minded their own business and let me choose the mode of transport (an electric car) that works best for me, my family and the environment. I don't want to live in a dense, grey, impersonal urban cluster. I want to be surrounded by countryside and have the freedom to roam. I don't think I'm alone in that.

hbak• 2 years ago

Can def echo that sentiment in London, how do you avoid the commute? Work from home? Found a job outside of London? Job opportunity/pay inequality is often the biggest constraint for most people.

siamese_puff3• 2 years ago

No offense, but this statement seems like an ignorant lack of understanding around the issues with the growing problems around urban sprawl and the issues it causes environmentally or otherwise. No one is going to take your countryside home from you, but it’s worth educating yourself on the issues.

ensignavenger3• 2 years ago

Making public transit clean, reliable, and safe are important goals, and very achievable goals too. There are many examples around the world.

But few transit advocates are saying that we have to 100% eliminate all personal vehicles. They will remain an important part of the overall transportation infrastructure for the foreseeable future.

It would also be folly to advocate for eliminating all rural living. There are many necessary activities that take place in rural communities, such as agricultural production, that will remain critical to society.

The thing that I see most transit advocates targeting is excessive suburban sprawl, communities that aren't really countryside, but also aren't dense enough to be urban. They sprawl on and on for miles, with nothing to distinguish them, often simply the same tract home design repeated with only minor differences over and over and over. I am sure there are some folks that prefer these communities, but I also think that many residents would prefer wither moving into a less dense rural setting or a more dense urban setting, and many of those left that like the density would still prefer that the way these communities are structured be changed.

tootie• 2 years ago

You have to be joking. Having blown my nose on many subways, tissue turning black is absolutely baloney. Either you have a truly horrible disease or you're lying. I've raised two kids very successfully in a city with no car.

An apartment in a major us city costs >4x per more per square foot than the adjacent suburban sprawl. Clearly a lot of people realize the value and are willing to take the financial hit to have it.

kfarr6• 2 years ago

I love this! There is similar inspiration in the US with non-profits such as KidSafeSF [1] in San Francisco or Families for Safe Streets [2].

I also have a fullstack background and have taken an approach to work on the street design software itself. Although AutoCAD is used by professionals, it's overkill for most street design projects and difficult for laypeople to use. I've been hacking away at a project called 3DStreet [3] to make street design easier for anyone -- like a figma for street design. Still in its early days. Happy to collaborate with your org, we do group sessions to help folks learn street design to influence local government to make positive changes.

mdnahas• 2 years ago

I’m helping a YIMBY group in Austin, Texas. In the USA, we’ve tied the legal right of what you can build to the land. So, a housing shortage causes land prices to skyrocket. We need to break those connections (height limits, unit limits, floor area limits, etc.) to bring urban prices back to reasonable values.

Then, people who want denser, walkable, social neighborhoods can create them.

I do data analysis for the group, on land prices and politics. (E.g., campaign donors). If anyone has questions, reach out to me at hackernews@mike.nahasmail.com

After years of lying dormant, I'm reactivating a hacky PHP script to test 'technical SEO' knowledge in the way of a challenge - more aligned to a technical web challenge, with a "SEO" bent more than anything spammy.

I've used this previously as a recruiting test in lieu of any other method to evaluate knowledge.

It's currently brittle and hosted on a RPi in my garage. It also requires a name + email to prevent spamming (and certification if successful), but once I've built some way of moderating access it will be more open.

Of all things, I downloaded RPG Maker MZ from steam and started building small mini games using the plugin system.

I don’t care for making RPGs but I use it as an IDE for tile sets, maps, sounds, and events.

I was never capable of making anything in it as a kid when I first downloaded Miguel’s translation of that early RPG Maker decades ago.

The constraints of the engine make it easier to think of how to implement something than, say, Godot where it’s all completely open ended.

Do you know of any communities with self-built airplanes? (especially novel-esque designs for propulsion or wings?) I realise these have far more regulations, but experimental GA is something that really excites me.

janosch_1236• 2 years ago

I do not. I know people use https://openinverter.org for boats

Just yesterday I stumbled upon https://vesc-project.com/forum where they are doing something similar with a focus on ebikes and drones.

You are talking full-sized aeroplanes right? I think some of the sail-gliders can be homebuilt, there must be communities for those guys.

bronco21016• 2 years ago

Are you familiar with the Experimental Aircraft Association? EAA.org

They have had a handful of articles of people working on electric propulsion in their magazine. I would imagine you could reach out to some of those featured. I once contacted a person who was building a DIY HUD and he was very friendly and eager to talk about the project. Overall a very good community!

I don't have a direct answer for you, but I would checkout any AirVenture Oshkosh groups online. I know people build planes ahead of the event to fly in.

PuffinBlue• 2 years ago

If you are in the US, you probably already know about Mike Patey but I'll share this here anyway. He has a track record of building something custom pretty much every year. I believe he is trying to build a community around a similar idea, but also catering for more mainstream GA too.

He's actually building out an aviation park to promote the community: https://www.youtube.com/watch?v=IenxeMl2nkw

I still have my fingers crossed that one day someone will build an electric drivetrain for a very common engine design (akin to how people put bigger engines from bolt compatible vehicles into smaller ones so they go faster), and for iconic vehicles so that we can keep them on the road. There are plenty of collectible cars out there that already lack matching serial numbers. Swapping the engine on those is no great sin against history.

Little tool to rewrite the text - https://www.rewritify.com

t43562• 2 years ago

I have been so overwhelmed that all my side efforts have been tiny things for a year - actually since last Christmas when I had a few days off in a row and my wife wasn't demanding other work.

JSON Serialisation of GNU Makefiles:

I got quite far then and now, one year later, I'm hoping I will have the time to finish off the difficult bits: it's a way to get GNU Make to print out its internal database of targets and rules as JSON.

https://github.com/tnmurphy/gmake-experimental (feature/jprint branch)

It's a companion to the print-database option:

    ./make --print-data-base-json

You get output with all the targets, all the options on those targets. Basically everything that make knows. I have most of it working but not directory targets for example. Why do this? Well there are many uses:

1. tools to rewrite makefiles - to simplify them or find duplication and implement transforms that remove it. e.g. all your CC commmands have nearly the same parameters - so make a variable or a macro containing the common ones and simplify all your commands (basic things like that could still be very handy).

2. tools that translate makefiles into other build formats. This is a big one for me. Make is like an almanac of all the build features one can have (nearly) but all done in various ways that make them of limited use. There are existing tools that are better in some areas and always the holy grail of the one build system that does it all and does it right. One is never going to get there however if one cannot convert existing work with a fair degree of ease and in a way that can be shown to truly do what is expected.

Sorry if I think the existing examples are not very good and that upsets you - they're all tailored for specific situations and work really well in those situations and if that's all you need then they tend to seem amazing. ...but...when you try to do something that's not in the examples they can be very inflexible. tup's basic idea (inverted dependency tree) is what I want because it lets you have giant makefiles that load quickly. The ability to describe a logical structure like Meson does is important too. Cross platform tests and option setting like CMake...check. Then some features from SBS (Symbian build system which none of you will know) and all the really interesting features of GMake that suck in implementation/performance such as pattern rules.

So this Christmas I hope to update to the latest version of gmake and handle directories.

Not quite sure if the esp32 will manage decoding and encoding audio quickly enough though, as I'm planning for it to be Bluetooth only. So it will need to decode flac, encode the pcm to sbc and then send it to my earphones.

I accidentally fried my last spare esp32 yesterday though, so I'm waiting for new ones to arrive. Wops.

database64128• 2 years ago

I just finished adding UDP GRO & GSO support to my WireGuard proxy software. The work involved rewriting a large part of the program.

https://github.com/database64128/swgp-go

For those who don't know, UDP Generic Receive Offload and Generic Segmentation Offload allow you to receive and send multiple same-sized UDP packets coalesced in a single buffer (or many in an iovec but you really shouldn't). Compared to calling sendmsg(2) on individual packets, sending them coalesced in one call traverses the kernel network stack exactly once, thus has significantly lower overhead.

wireguard-go and many QUIC implementations use the same trick to improve throughput. Unfortunately the in-kernel WireGuard driver does not take advantage of UDP GSO, and swgp-go had to cope with that by attempting to coalesce multiple unsegmented messages received in a single recvmmsg(2) call.

I started to pick up a somewhat dormant side project again.

It has the working title of the "Wise Weasel". This is supposed to be a minimum spoiler hint system for adventure games. I really don't like walk throughs telling you to "Walk into the Armor Shop. Pick up mirror, arrows and use cheese on hole to pick up mouse", because that breaks all immersion and puzzle mindset. A hint system is more like "You can burn rope if you focus light a bit", followed e.g. by "But now the beam of light is on the floor, not on the rope. How do we reflect light around" to nudge the player a bit into a direction of looking for a mirror or something shiny. Or to polish something? This keeps one in the mindset of an adventure and a puzzle game, opposed to some IKEA instructions.

NiceGameHints[1] is already nice at this, but I find that the chapter / puzzle list still gives off to much information and spoils too much plot. I'm much rather tinkering with giving the user some word cloud of both words describing the puzzles as well as generic words on top, so they have to select two words what they are stuck with. For example, you'd select "Witch + House" or "Witch + angry" and this would reveal a puzzle "The angry witch doesn't talk to me and turns me to stone if I enter her house". I'm just worried that this might be more moon logic than the game itself.

It's mostly a bit difficult to keep all of this state (unlocked chapters, known puzzles, ...) in track with URLs or cookies or something, because I don't really want to run a database... and requiring user accounts is just a lot of work. And I'd prefer to keep this mostly without JS as a classical system just rendering HTML. If you have some food for thought there, I'm happy for input. Currently it's just list in URL parameters.

The idea is that you get a daily for every day, with the items ticked off on the last day removed. So a new daily every day. At the same time, there is some integration with AI to get feedback on things to break down. You can give it some instructions, focus, and also tune the amount of feedback.

I've had this in so many incarnations before, but never made it 'properly'. It's a pet project, but do want to release it at some point.

I’ve been working on open sourcing a background jobs library I built for Rust and Postgres, called Underway.[0] Unlike other similar queuing libraries, it offers a simple “step” functions API for defining dependent units of work.

I built this because a number of projects I work on need a robust, resilient way of deferring work but I didn’t want to add another piece of infrastructure or another language to my stack. Plus as soon as you start to reach for APIs that offer some kind of workflow concept, your options become fewer and further between.

We created Milieu Club https://joinmilieu.com as a way to connect with other busy professionals in your city over lunch as nice restaurants. You can join clubs in your city or create your own, and then you get randomly watched with 3 - 5 other people and invited to lunch. It's sort of inspired by Soho house, meetup.com, and Opentable.

You can point the app at a repository, download a copy locally, instantly render the entire repository into space in less than a second in most cases, and then fly around and search for text. I just got an optimization working for larger files and it's kinda fun how much even an iPhone can do with instanced rendering.

Im developing it with the use in mind of flying through your code to show others relationships, or edit with a visuospatial look at your code instead of basic 2D tabs and a mind map of which one had the thing you're working on. It's kinda fun to work on the project In the project!

tyjkot6• 2 years ago

In my 50k population town in Minnesota, I notice a lot of headlights, taillights, and turn signals are out. Our roads (outside of the Twin Cities) are often bumpy which causes vibration in the vehicles, leading to many bulbs failing.

I drive a 21 year old Saab, and in my 2 years of owning it, I have replaced every single bulb in the exterior of the vehicle except a turn signal or two.

I decided to create a mobile service for vehicle lights. It's a simple website that even technologically-disadvantaged people can use. The website is nearly finished and I will likely come back here to write a post on it for how the website works.

Oh the best part, I get texted and emailed for each service order that comes in, and using my service is only $10 more than what it would cost you to go buy a bulb yourself at OReillys, AutoZone, etc.

I programmed everything myself and developed the idea as well. This is my first real-world project/solution I am bringing into this world that has been verified by others, to be a needed service. Pretty excited about it and I love changing bulbs or replacing light housings, it's fun and simple.

**Update: I perform the install.

costcopizza• 2 years ago

Neat! Do you pick up the bulbs as needed from an auto parts store? Or do you keep a supply on hand?

I think you want to keep this as simple as possible, but I see headlight restoration (which can be done in 30min) and wiper blade replacement complementing this nicely.

tyjkot6• 2 years ago

No bulbs at auto stores are inflated far too high to be a profitable parts for me. I have to order through a supplier and keep supply on-hand, which is honestly fine and more profitable for me.

Hey thank you for that idea! I am going to be adding in headlight/taillight housing replacements as well, but I do like the idea of wiper blade replacement, I may keep that on the back-burner for some time until demand approaches.

However, the headlight restoration idea is a fantastic one. Definitely will add this to my list of primary services after launch.

notpublic• 2 years ago

it's fun and simple

Not sure if it was mine or my friends car, replacing one of the lights was neither fun or simple :). Some manufacturers really seem to prioritize style over repairability!

bityard• 2 years ago

Lots of cars make it easy to change out bulbs. But some cars are a massive pain to change certain bulbs, and/or require special tools. Do you exclude them? Or upcharge them? (E.g. the left headlight bulb on a Subaru Outback is an absolute nightmare.)

Unless you are doing this purely as a public service, $10 seems VERY low. Many independent mechanics in my area charge a minimum of 1 hour of work for anything they do, and bill at $90/hr and up. And they won't come to you for that price. (Nor are mechanics a highly paid profession in general.)

I really do wish you all the best, maybe I'm just not seeing the whole picture.

Edit: Something else to think about: when I replace bulbs in my cars, I always do it in pairs. Reason being that if one side burned out, the other is likely not far behind, especially headlight bulbs. The headlights also have another quirk: if you replace one and not the other, you usually end up with the new one being much brighter than the old one.

tyjkot6• 2 years ago

I have all the tools to replace headlight and taillight housing and bulbs for probably most vehicles including semis.

For my Saab's headlight bulb replacements, I have to remove my front bumper and then the headlight housing unit itself, just to replace turn signal and headlight bulb. I am fairly mechanically advanced.

It's not quite just $10, it's $10 more than a single bulb would cost you at your local parts store. If you lookup how much a headlight bulb is these days, it's about $20. My service will be $30 flat for bulb replacements in my area with a small mileage fee for out-of-towners.

The great part about Minnesota, is most of us hate the cold. I however do not. Many people get lazy and will Doordash or find other convenient ways to have things delivered. Not many people want to change bulbs in the cold or bring to a mechanic to be over-charged. What my population is looking for is a service exactly like I am providing.

Again, the pricing of $30 per service is perfectly sustainable for me and I have no issues replacing most parts in vehicles, lights are a walk in the park for me.

*Will correct typos later, at work ATM.

What I really care about, is moving the world forward. This is a service that the area I am in, is lacking. I don't need to make excessive profit, I just need sustainable profit and I am happy to provide this service as it's well within my skills.

fy20• 2 years ago

But some cars are a massive pain to change certain bulbs

This weekend I did this with my 18 year old Mitsubishi. It seems you need child sized hands to be able to change them. In the end I had to take off the bumper and remove the whole light housing to get access.

btbuildem2• 2 years ago

Please please please strongly discourage people from using those super-blinding lights so many cars seem to have these days!

tyjkot6• 2 years ago

Lol I will only be replacing bulbs with OEM parts. Some vehicles come with xenon, LED, or HIDs and that will have to be replaced with proper bulbs.

As blinding as they are, if that's what the vehicle has I gotta put them back in.

cacozen2• 2 years ago

Suggestion: Costco sell car batteries for ridiculously low prices, because they don't include installation. I recently got one for my Kia Telluride and it was $100 cheaper than any competition (because all competitions include the installed price). Installing is as easy but can feel intimidating to people: Could be another source of income for your app.

smileysteve2• 2 years ago

I find it interesting because this seems to be information asymmetry - and there is nothing wrong with that.

AutoZone, O'Reilly, Advance advertise that they do things like replace batteries, change light bulbs, add washer fluid, wiper blades.

It's arguably imperative for their brand that they offer (and advertise) these store services when compared to Amazon or Walmart (without a car center). It's even clearer when they offer 20% off codes for online ordering 12 months a year. (Also interesting because basic bulbs for tail lights and turn signals are often also sold at gas stations and grocery stores)

They're not ASE certified techs, but I'm under the impression that staff receive some training related to it.

smileysteve2• 2 years ago

Contextually; yes, I have relatives that ask me to get their battery changed at Autozone, even though Autozone will do it for free -- and relatives who don't know that Autozone sells (and will often perform) a refrigerant top off if your AC isn't cold.

For an individual, it can be easier to focus on one model. You get to use parts and knowledge from past cars.

I am working on an email-based space game (a la Eve Online).

Between work and family responsibilites, I find it difficult to carve out time for dedicated gaming sessions anymore. As a result, I often find myself searching for games that I can play when I have a bit of time, can progress over the long-haul, doesn't require real-time monitoring and yet feels like I'm actually playing a game (as opposed to just watching a train move on the track, like all of those Idle games).

I thought: What if there was a game that could be played one day at a time? Not real-time, but still multiplayer. You could decide what you want to do throughout the day and adjust your tactics, but everything resolves at the end of the day. What if you could play via email?

I've been working on a new LLM prompt format and accompanying dataset for finetuning.

The idea is that the "main character" being prompted always has to perform an action/function. So even "saying" something to the other participants of the chat is a deliberate action.

Actions can be something like:

    ### actions:
    1 recollect(query) -> {memory_id: id[]}
    2 think(thought)
    3 say(message)
    4 memorize(category, subject, memory, replace?: id)

The LLM then has to respond, like so:

    {"action":2,"thought":"Some internal thought","queue_action":3}

The JSON overhead is pretty negligible.

I'm working on a social network based around link sharing!

One of the core ideas is that rather than following a whole person, you can follow a subset of their tags so someone can post about obscure cheeses and ambient electronic, but lactose intolerant you can just follow the music. Or you can follow someone's tech posts but not follow news of their dysfunctional city.

Honestly a lot of it is resurrecting ideas from earlier days in the web like Digg and Delicious, and despite having the idea for ages and having worked on it for a decent while, it's only getting more relevant as the web gets more algorithmic and external links get demoted in sites like Twitter.

The aim is to bring more curation and humanity back to the web, and the next feature I'm really excited to get out is one to make in-person conversations even better!

It's already live @ lynkmi.com and if it's of interest to you, you can sign up to the waitlist (it's very short)

I am spending my retirement working part-time on a realistic spacecraft simulator (3D, VR) set in the late 20th century on a fictional moon made of Tungsten ("Tungsten Moon"). For some reason, I decided the spacecraft needs a "real" flight computer with code that can be modified by the player, so I am now deeply immersed in coding a Forth virtual computer ("AMC Forth") to run in-game. It will control the navigation and systems on the spacecraft. If you've gotten this far, and you're intrigued, you can try the free demo on Steam (no Forth machine yet).

Decarbonising buildings and massive warehouses..

It's a very fun mix of hardware (for data collection), and crazy SQL queries to model energy flows between buildings, solar, batteries, etc. Considering just one building is pretty easy:

consumption = imported - exported + generated - stored + dispatched. carbon = carbon intensity * imported cost = tariff * imported

but then you add a site with a couple of buildings, solar on one of them, grid limited exports, etc modelling these flows is challenging. Like consider the case where one building got 10% of it's imported power from another building's excess solar, then calculating carbon becomes more difficult.

and once you've figured all that - then you have to figure out what makes commercial sense to do next.. install a battery, expand solar, move onto a TOU tariff, do nothing - and that's a whole other world of optimisation problems.

thoughtpalette2• 2 years ago

Also somewhat working in this space. Building a BMS (Building management system) to manage and control everything in commercial buildings. Think Homekit for commercial. There's something like 70% of buildings don't use one and they can be much more environmental friendly.

Very familiar with BMSs but the lack of open standards and protocols has been extremely frustrating - makes me appreciate how good we have it with HTTP, etc.

The idea is to have a bunch of adaptors for Google Takeout, Apple Notes, Obsidian, Apple Health, fitness tracking, org-mode, location history, etc. keep all my data there in well-defined formats. I could then also use the markup language I’m writing to present my journal data in various ways.

My main focus is on efficient data entry/ingestion powered by schema-as-data, which allows for machine and human readability.

That's the more hobbyist stuff, and more broadly I am also learning Japanese, and making games. They sound separate but I am hoping to blend the two skillsets and make games that bridge a gap I see there.

I think that good innovation only happens at the intersections of things we already know. That way you have the depth of understanding required to be useful rather than just new.

Looks good so far! If it helps, some of the challenges I had with take-homes as a hiring manager were: - We'd suggest to spend an afternoon on it, no more than 4 hours, but many candidates would go far beyond that - Senior candidates tend to have less free time to do take-home assignments. Some would decline to do them and others would have to delay their interview pipeline for weeks (and by then, many candidates had lost interest or progressed with other employers)

That said, take-home assignments were very helpful for junior candidates who didn't have much experience on their resume.

I’ve been working on a bespoke smartwatch for kids with Type 1 diabetes & their parents. The watch presents reliable CGM data and not much else, so the only distractions from the watch are important medical alerts. It has a novel haptic algorithm that taps at a frequency based on the current BG trend, the idea is the wearer can develop a sixth-sense of their BG without looking at the watch at all. The entire watch is custom-made from the PCB up. I have a small batch of prototypes assembled and my son has been wearing his at school. I have a few screenshots up at my product studio website: https://subtractive.computer

I’m considering how to take the watch to market as-is, or if I pivot the watch to be a fully open-source Pebble successor.

ValentinA233• 2 years ago

Interesting. I've been exploring this space too, but for a LLM-driven MUD (multiplayer text-based game). The most challenging aspect is coming up with an architecture that can easily lend itself to handling "semantic collisions" in a multiplayer context, pretty much like non-neural game engines handle spaceship collisions, or prevent a player from entering a box if another player is in it, but going beyond and handling more abstract, more "semantic" aspects, such as narrative elements.

By the way you should get interested in "narratology" at large. There are benefits to driving the LLM generation with an explicit representation of the narrative structure. For instance if the bad guy turns out to be the good guy, then, narrative logic demands that the good guy was the bad guy all along. As a consequence, appearance and deceit should be keystones values of the hero's arch. There are many interdisciplinary approaches to this domain, some more naturalist/empirical such as trope databses, some theoretical like 70s semiotics while some other framework approach the problem from the perspective of cognition and entropy.

Even though I haven't really started coding anything, this is a very interesting topic to think about because of the technical challenges it raises as well as the scope of the project. Any papers exposing new LLM use and prompting techniques is of potential interest to me now.

It is a wide space

I'm working on scoping out specific problems facing "software as a medical device" (SaMD) companies. In particular issues around being able to release software at a reasonable cadence. I've been a CTO in this space for a couple of years and I am now consulting with other firms around the intersection of tech and regulatory.

It's a tight-rope walk of ensuring that all testing (software and non-software testing) and evidence is produced correctly and being able to release at a rapid pace to derisk each release. It's not uncommon for software to only be updated yearly, leading to very conservative changes and little iteration. Monthly releases are okay, but still not great.

I want to make it possible to release at least weekly and to do so safely.

If you work in this area, I'd love to chat and hear your experiences (email available via my website in bio).

I'm experimenting with a "new" kind of lisp macros.

Macros in lisp are just normal functions that receive the code they wrap as argument and return some modified code. Typically they will just wrap the passed code into some more code. But then there are code walking macro: macros that will traverse passed code to modify it in depth.

What I'm working on is "code diving" macros. Not only will they traverse the passed code, but they will resolve called functions and macros, fetch their source code and traverse it too. And so on. All the redefined fns/macros are accumulated in a let/macrolet binding, topologically sorted by call/dependency order. Instrumented code will call these local redefinitions, shadowing the global definition lexically.

This allow the programmer to write truly local monkey-patches for existing code he doesn't have control over (e.g, code from another library for instance). I'm writing this in Clojure, and the traditional way to do this is to temporarily change the global definitions of targeted variables using with-redefs. This is problematic because other threads will see these redefinitions, and not just threads created within the instrumented code, but already existing threads too.

Another way to do it is to just redefine the targeted functions globally, but then your modifications are available to the whole program for the rest of its execution.

jackthetab• 2 years ago

THANK YOU! I've been trying to understand wtf lisp macros are for so long I'm embarrassed to say. I've heard that their "extremely powerful" and kept thinking "Macros? like in C? In Excel? WTF is the big deal about macros?"

I want it to be like a C64-style keyboard with all the guts inside it but wirelessly connect to the display/tv, so what I might do is use an ESP32 to read the game floppy and wirelessly transfer and cache the file to a dongle that plugs into an open HDMI port. Not sure yet.

I've been working on an app to help VvEs* in the Netherlands self-manage.

For about a year, I was trying to get our VvE management company* to take care of major issues we have in our building's crawl space. We had an inspection done, but even after about seven months of constantly nagging them, they failed to get a single quote for the work that the crawl space needs. I called our manager, and he essentially yelled at me for twenty minutes and was not shy to express his anti-immigrant sentiments (I'm American).

Because of this, I'm now on a mission to get this company fired and take management into our own hands, which will save us a bunch of money. The existing VvE management tools are ugly, slow, and unnecessarily complex, so I'm building my own.

It's only been a month, so I haven't hosted it yet (still coming up with a name, to be honest), but I have made good progress functionality-wise. If anyone in the Netherlands is part of a small VvE and wants to chat, let me know! My email is my username (@gmail).

* The US equivalent would be an HOA (Homeowner's Association). Basically, a corporation that is responsible for the upkeep of shared resources for homeowners (e.g. the roof of a building or the pool in a gated community).

** Many VvEs choose to outsource management of the VvE to a third party. These companies—in theory—take care of maintenance requests, yearly meetings, voting, etc. From everything I've read online, almost none of these companies satisfy their clients.

The goal is to create beautiful and useful maps of interesting data, empowering the user to explore more intuitively guided by semantic similarity. No user data needs to be tracked for this to work, the data speaks for itself.

This roughly works by translating semantic (visual or textual) similarity into spatial proximity. Diggers major features are: semantic mapping, text search and image search. The text and image search works bidirectionally, allowing to search for images (e.g. product images) using text and for text (e.g. books) using images.

Since my last update here, I've added more detailed personalized descriptions of recommendations (hit Describe to request), including a rating out of 10 for how well the item meets your preferences.

I've also added the ability to replace individual recommendations (this was the most requested new feature!). If you update your preferences, your replacements will use your updated preferences - pretty nice for fine tuning your results!

pncnmnp• 2 years ago

This is fantastic, Aaron! I love it!

I was surprised to learn that each recommendation for preferences costs nearly 1 cent. From what I can tell, you don’t seem to be caching preferences. For example, each "Let's Go!" click on a show like say "Succession" generates some variation in the preference recommendations. My hunch is that if we ask LLMs to "over recommend" preferences based on the content you’re using (my guess is a mix of MovieLens, IMDb, TMDB, and Wikipedia) and do so in an ordered fashion (preference1 is a solid, but preference7 is a so-so), you could cache these results and strategically display them. For instance, when users choose to "fix" certain categories and get new recommendations for others, these "over recommendations" could help create variations without additional LLM calls. This could be repeated like N times until new categories require further LLM calls.

I am not sure if this would work with the personalized descriptions of recommendations part. I kind of love how they’re tuned based on my selected preferences.

I am curious about the design of the whole system. Fun project! Thanks.

kolleraa3• 2 years ago

Thanks, I'm glad you like it! That makes me very happy!

You're correct, I'm not caching the results right now. I determined that caching whole queries would not make much difference in the aggregate, since the vast majority of queries are unique. (However I also just saw that OpenAI added their own caching layer with lower prices for cached results, which is nice!)

However - the new Replace function was my first step toward fetching recommendations one-at-a-time - I agree that potentially opens up interesting new possibilities for caching and other things as well!

Hi Aaron,

I really like your idea and the clean, simple execution! I'm looking forward to using it more in the coming days.

I'm curious about the technical side of things—how did you build the app, and how do its inner workings function? Is it open source? If possible, could you share more technical details?

Really cool, thanks!

As a personal project during my free time I'm currently working on adding more accessibility features, specifically screen reader compatibility, to my Terminal User Interface XMPP/Jabber client, Communiqué. Unfortunately, as far as I can see there's no actual way to make a TUI compatible with screen readers (reach out on the issue tracker, fedi, or xmpp, see link below if you know otherwise or have experience here, please, I'd love to pick your brain!), so my current plan is to re-write the UI with whatever TUI toolkit makes it easiest to also have a CLI/prompt mode that we can specifically design to be reader compatible.

Outside of the software world I'm also working on opening a Bike Shop and frame building studio. I'm hoping that one day I can actually make a small living on frame building since I don't do software for my day job anymore, but I'm not quite ready to build for other people yet (so far I've only built frames for myself and I'd like to thoroughly strength test them before I risk putting someone else on one of my creations!)

If you're in the Atlanta, GA area and need bicycle work done, hit me up! No job is too big or too small. I particularly enjoy building wheels if you want a sweet custom wheel set, but I do it all (including Mountain Bike fork and suspension work that many shops won't do).

I'm working on a solution to the age-old problem of tracking my food intake. Every app I have every tried from the many dozens on the market has not met my need of a low friction simple UI tool, so I've built it myself.

I've built Journable, a simple & frictionless chat-based & photo-based calorie tracker. Just type in what you've eaten, in as much or as little detail as you can. Or type in what you did for exercise. Or just snap a photo of your plate. Whatever works for you.

I've wondered if a camera you "show" your groceries to as you unpack them would be enough to track incoming items accurately.

Or a couple of cameras around the kitchen, with an ML setup that recognizes both incoming food items, and their use in cooking. Then it could give you notifications/calendar items on things expiring :)

I'm finishing building a 120sqft shed in the back yard, learning Fusion 360, and hopefully getting my chronic sinusitis solved.

Poured a slab, designed, framed, used as much reclaimed lumber as I could, and sheathed a lean-to style shed. My first attempt at building a structure, and it's coming out nice. This is to replace the 64sqft 5' shed that a neighbors tree fell on earlier this year, but we really need the extra storage.

I got a Bambu P1S 3D printer for Father's Day to replace an old Ender 3 Pro, and it has just been a dream. TinkerCAD, while amazing and a very capable tool, I'm ready to move on to something else. I tried Plasticity, and it showed a lot of promise but I found it very frustrating, bumped against some missing documentation and ran out of free trial time. Tried FreeCAD 1.0RC/Ondsel, and it's a fantastic piece of software. Yesterday I decided to give Fusion 360 a try and it's just so much more refined. Started the Product Design Online tutorials on Youtube yesterday and the stuff you're building in the first 5 15 minute lessons are frankly amazing.

Lately I've been thinking about the "enshittification" of productivity apps, how everything is having features crammed into it that really get in the way of what users want to do, in the name of selling them subscriptions or optional buy-ups.

I've been mulling around the idea of some kind of foundation that could sponsor the development of what I would consider "Good for the end-user" software of this nature. Something to encourage building apps that are pleasant to use and keeping them pleasant to use.

It's a rough problem to figure out how this would work though, realistically. Some kind of binding license or legal contract that says "here's what you can't do to this software, for this many years, if we give you resources" essentially. But I am well aware that solutions like that also generally end with someone finding a sneaky loophole to take advantage of it.

I'm very passionate about this idea, but I just don't know how feasible it is. Maybe I should have gone to law school instead of learning to program.

Re-working my course on Android Development. Next year will be the third year I've taught the course, and usually the third year is where I'm happy with the content. It's a fun course to teach, but I would never, ever want to work in the area professionally.

The biggest problem is the instability of the tools. IntelliJ is already complex, then you pile on all the Android Studio stuff. Within Android Studio, you are working with a hugely complex framework (Jetpack Compose) that depends, directly or indirectly, on probably hundreds of libraries. Sometimes, things just break, for no apparent reason. On some students' computers, the whole wobbly tower never works quite right. It reminds me of this XKCD: https://xkcd.com/2347/

As a software developer who later got into hardware design, I've always been pretty disappointed with the quality of HDL tools. You get a bit spoiled by the quality of compilers like gcc and clang, and then you run into ridiculously expensive closed-source SystemVerilog compilers that fall apart on valid and obvious code, can't be run in a build farm, and which report cryptic messages for errors. So I've been working on my own open source SystemVerilog compiler / frontend for a while now, and it's nearing 100% completion in terms of language support.

- Trying to get over my procrastination and finally start (the standard way of) prepping for software dev (staff/etc) level interviews after having taken a considerable number of months as a gap

- An idea of a platform to connect sports venues to players. (In a way that is better and richer than the only/shitty option available in my geography. Why do I call that service shitty? They have been around for almost a decade or close to that by now and they are still shitty and unstable and barely useable). With a bit of differentiation - instead of individual and venue bookings (the service that offers right now) - connect venues and groups where payment is taken care of already (no running around collecting payments and worrying about no shows and ignoring them in future them/etc). We were reaching towards a demo kinda product but the friend on the backend side got bored of software and started focussing on stock trading where he is sadly doing spectrally bad

- Also did a bit of work on trying to connect users with the laundry list of (e)bicycles, e-scooters et cetera providers (i.e how there are common booking platforms for all airlines; or for buses; etc) so that they won't have to install all the apps until it finally reached our skulls that maybe those services are looking for a lock-in so they would never open up their APIs and we lacked perseverance and resources to force them to adhere to the Govt suggested broad inventory db mechanism in my country. Basically we started on it without any research.

The problem with me is - software engineering/coding (I have been told I am not bad at it though)/platforms/libraries/etc excite me fuck all. But problem solving does. I should not have been a software engineer really. So interviews get tricky. While I can (and have) clear interviews at early stage startups, the work-life balance they offer is horrendous, but MNC/etc ask for every thing I have never used and will never use, or anybody ever will (mostly), that means thorough prep. I am just ranting, ignore it.

I'm trying to OCR a very large book: 45 volumes of ~500 pages each. The digitization has been done (not very good but not too bad either), but the pages have comments in the margin and lots of footnotes.

Just doing plain OCR doesn't really work because the notes in the margin and the footnotes get mingled with the text, which results in gibberish.

But, when sent to Google Vision API, each page results in a json file that has an object for each word and the four coordinates of its bounding box.

That json file is pretty big (around 1.5 Mo when pretty printed, or 500 k with no indents or line breaks) but it can then be fed to Gemini, taking advantage of its large context window.

Gemini is pretty good at identifying each section of the page (headers, main text, margin comments, footnotes) but it takes a looong time to respond (2-5 minutes per page).

So another approach is to ask Gemini to write a python script to analyze the json result and group sections depending of the coordinates of each word, and then run that script against the json output by the OCR phase.

But it's quite difficult to have a script that works for any page; comments in the margin are always in the margin so that's pretty easy, but footnotes can start at any height of the page (some pages contain only footnotes running from previous pages) and Gemini likes to be pretty specific, giving hard 'y' coordinates for where footnotes should start, which obviously only works for the one page it's working on.

I'm iterating and making some progress but I feel like I miss a big breakthrough and it all should be simpler than it currently is. Information about OCR is pretty scarce online. Any pointer is welcome!

Are the footnotes in a different font or fontsize? If so, then the bounding box for footnote words should be smaller. Perhaps that can help with categorization.

bambax5• 2 years ago

Yes thank you, that's one piece of information that I examined. The font size of the footnotes is a little bit smaller but the difference is very narrow. On a given word it's not really obvious enough. But maybe by calculating the average height of a whole line it would be significant.

I'm currently (and have been for a few weeks now) building a self-hosted Git "forge", à la Gogs/Gitea/etc.

The main motivation for this is that I usually juggle many side projects at the same time, and since none of them are in a finished state, I don't really feel like putting them out in the open on GitHub or Codeberg or something else, and would really like to keep all of this experimentation private. I know GitHub provides free private repositories, but I really dislike the interface and I feel like most of the features offered are not for me.

I tried running a private Gitea instance, but I did not like having to manage a second software to be able to run CI pipelines on my repositories (like Drone). I also really dislike GitHub Actions so I was kind of disappointed that Gitea's integrated CI is based on it.

I also tried running a Gitlab instance (which is currently what I use) as I much prefer GitLab CI over GH Actions, but the whole package is so much of a resource hog and tries so hard to be "more than GitHub" that I feel it isn't for me either.

So, in the end, I decided that I would build my own platform, with a simple scope in mind: be a nice Git repository hosting solution for single hackers or very small teams. Along with the smaller scope, I added a few restrictions: no JavaScript unless it substantially improves QoL (and even then, never require JS for the website to work), no external components required (apart from OpenSSH and Git).

So far I have a very minimal SSH handler implementation that allows push/pulling repositories from the server through authenticated SSH (public key), and what's starting to become a nice web interface to manage and read all of that. It's almost at the point where I will soon be able to dogfood the platform by hosting itself there (as a backup remote, not the primary yet).

The tech stack is kept relatively simple on purpose (I really dislike "modern" front-end development):

* Rust + Axum

* SQLite

* Bootstrap with SASS to customize it

* libgit2

Everything is server-side rendered as HTML before being served to the client, using Minijinja (reimplementation of Jinja2 in/for Rust by the same author).

Anyway, not yet ready to share any links or anything but I am still excited about the project taking shape after weeks/months of sporadic work on it! I'm building this not only because I feel a need for it, but also to learn more about Rust and Git internals, and I feel like I've learned a ton already!

I'm currently building an open source CMS in Golang. Meaning fully implemented backend and frontend + support for custom themes in the frontend and custom collections/items in the backend.

Now, there is a lot of CMS software out there. Some of the better ones are paid products.

What I'm hoping to eventually accomplish is easy local creation of a website (content and themes) and after that easy one click deployment to a cheap hosting provider. Alternatively just copying a local folder to your own vps/server with the CMS should be enough.

My dream outcome would be a CMS that is a one-stop solution for most types of websites (blogs, company sites, shops, ...). To hopefully contribute to making people stop using facebook, twitter, other centralized and eventually login seeking services for hosting content people would like to read.

For this, a free/cheap one click hosting solution after locally creating and previewing a site would be necessary.

PHP is still pretty widely used here because cheap web hosting package support that. I like PHP, but for open source projects I prefer Go because of the maintainability and fun of writing it.

which didn't really connect with people. I did a collaboration with some people where I'd barcoded work prints and found that the system was not so reliable and I'd gotten out of the house without publishing the "web side" of the prints. Also I had a few boxes of glossy paper which wouldn't let me print on the back so I developed a new generation of card

I've been working on an experimental modern C++20 fork of the popular SFML library, that introduces the following new major features/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*

It is temporarily named [*VRSFML*](https://github.com/vittorioromeo/VRSFML) until I figure out a nice name.

You can read about the library and its design principles [*in this article*](https://www.vittorioromeo.com/index/blog/vrsfml.html), and you can read about the batching system [*in this other article*](https://www.vittorioromeo.com/index/blog/vrsfml2.html).

You can find the source code [*here*](https://github.com/vittorioromeo/VRSFML) and 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 that are looking for a library very similar in style but that gives more power and flexibility to the users. Upstream SFML is more suitable for complete beginners.

Right now I'm testing key shapes and sizes and the manufacturing of key caps. I thought I needed a resin printer for best results but FDM printed caps with a blob of epoxy resin on top works surprisingly well.

There's no firmware yet, I have not even decided on a micro-controller or software. But I want to use Kailh Choc v1.

This is my first time exposing this project to the public so I'll be very happy about some feedback!

bloopernova4• 2 years ago

This looks really cool!

What's the "up/down" key in the bottom row, centre, between the 2 return/enter keys? (I ask because my "dream" keyboard would have a thumbwheel just below/between the 2 spaces bars on an Alice layout keyboard) EDIT: it's a toggle key.

The different heights and layout look interesting; did you perform any statistical examination of which symbol keys were most used? Are you intending on using QMK layers to enter the extra symbols?

Can your fingers accurately hit all those modifier keys? Does that layout lead to less or more pinky usage? (I'm terrible at hitting other keys, I'm just a clumsy person)

Ladsko2• 2 years ago

Thanks!

That would be the perfect spot for a thumb wheel, it's a cool idea.

I myself did not do any statistical analysis, the effort was done by the neo layout project (https://www.neo-layout.org/) and the hybrid English/German variety called noted. I modified it slightly to fit my hex grid.

The height difference makes it possible to hit the edge of the key without pressing the key below. And you'll find the home row more easily just from the bent layout shape. This should also help with hitting the right modifiers.

I want to try Jan Lunge's Keyboard configurator (https://www.youtube.com/watch?v=RtYJYFMWjNM) for KMK but have not made a final decision. If I hit a road block with his configurator I might try QMK. Either software supports layers.

I am working on a private transportation service. Think Uber, but in a small market. We have an aging population, poor public transportation and some of the bumpiest roads you can find in the West. It will fill a void.

Not my idea, though. Through our local geek community, I met this taxi driver who pitched his app idea. He convinced a few other drivers to pay a small fee to kickstart the project. Then he convinced me to help with the technical stuff, and I convinced a friend to tag along.

He is on the road looking for funding!

kfarr6• 2 years ago

I am intrigued by the concept of an open source Uber equivalent. I was involved early in a few rideshare app concepts before Uber came to market and it was surprisingly complicated. You have the technical challenges combined with being a "market maker" for both riders and drivers. It's possible but hard.

conductr2• 2 years ago

I was involved early in a few rideshare app concepts before Uber came to market and it was surprisingly complicated.

Can you explain some of the difficult parts? I'd think it would be fairly straight-forward. Is the technical challenge of market making the hard part? or getting enough users on the app to actually make a market?

I've been working on a free, in-browser "pre" video editor. Upload your clip, use a transcript interface to cut it down to the takes and salient bits you want to keep, then export your cuts to FCP or Resolve to complete your editing. This tool saves me about 25-30% of my editing time.

Uses transformers.js & WebGPU for running transcription, so it's pretty fast. It's still a bit rough around the edges, so I'm looking for feedback.

I kind of got back to looking at my newsbetting app called Rashomon. I posted about it on here a few weeks ago to no attention.

Basically you get untitled articles and have to bet whether they are from far left, left, center, right or far right sources. The idea was to maek readers aware of their biases. I wrote my findings here: https://nassharaf.github.io/ideasthete/projects/Rashomon.htm...

You can demo the site here: https://www.rashomonnews.com

I trying to create a management software for Integral Coops in Portugal. In a gross oversimplification Integral coops tend to be location based and allow freelancers and small groups to come together and have a infrastructure as if they were a big business while keeping their independence on the work they want to do

I'm trying to make it: a collective project shared between multiple coops, open source, sustainable in the long term.

I've already did some micro projects to the coop I'm a part of, like changing the workflow of expense invoice management from a totally manual process to an 80% automated process so I'm pretty sure I can provide significant benefits to the coops. Right now There's already a prototype andI'm in the process of talking with cooperatives finding financing and making it real.

Burned out with the job hunt after a rough year so I'm building out a remote job listing site... because I'm searching for a job. I figured I will build something that scrapes top sites I visit and normalizes job postings and company profiles, to which I can subscribe/save/apply/archive listings, get jobs matched to my resume etc. Just a nice little CRUD app.

I figure it's better to launch something then go job hunting instead of job hunting off a resume that hasn't been updated in a good while.

I built dailycodingproblem.com with a friend way back and we got #2 on PH so I am trying to get back to that life again!

Tried it but couldn't see any results! Says "Subscriber Only Feature"

lieks• 2 years ago

I'm currently working on a programming language that will probably be very boring in practice (Algol/Pascal structure, C-ish syntax, traits/typeclasses but only modules can be generic, not sure if GC or borrow checking but probably a hybrid).

The idea is to have something efficient enough, with the least amount of implementation complexity (including codegen), and still being nice to use, which is a really interesting balancing act.

For example, instead of implementing loop optimizations I could add APL-style broadcasting; I could make a complicated but efficient GC runtime or a complicated but efficient borrow checker, but I could also make both a dumb GC and a dumb borrow checker that somehow complement each other.

It's kind of a researchy language, but not trying to be new or interesting. Just "globally simple".

Most features are in an theoretical design phase, but I'm currently working on a new backend (LLVM is too fancy to count, QBE is too basic).

My son loves collecting pokemon cards and trading with his friends at school.

We talked a lot about Pokemon on Friday and it got me into a nostalgic mood...

Side Note: Pokemon has done a great job staying relevant for 3 decades.

So... I made a python script with gpt-vision where he can manage his collection and uncover the value of each one. He just snaps a photo and boop, there's the returned valuation. He's now got his whole collection documented and appraised. :)

Most importantly, we had a lot of fun spending time with each other on this.

Be warned, zero documentation, because things are at larval stage and change often. Will include a couple of demos this week.

In the spirit, yes, but targeting different hardware, public, and environments.

* It runs on Linux, Mac, Windows. Bare metal on rp2040 and rp2350 is planned.

* It written in C, build with Make.

* It is meant to run on something like a Raspberry Pi, Latte Panda, etc

* A setup is a text file, no fancy UI.

* The plan for live parameter fiddling will be a web server. Web UI will be tailored to each setup, no one size fits all UI. Typically I pay someone to do the UI.

* For now, it's only video, no sound output

It will be used for several large interactive LED displays and object tracking systems. It's a way for me to factories all those projects I was contracted for.

From my last comment in August 2024 [1], I have made progress!

The project I'm developing is called Your Commonbase, a self organizing scrapbook built around Personal Library Science.

The big updates are:

1. From Fleeting Note to Connected Note with The Entry/Comment Model - An entry has its own marginalia (comments), which are also embedded as first class data. These comments allow your search model to improve over time, and create surprising clusters. See this video to see an example of the Entry/Comment model in a d3 graph [2]. All the connections are created automatically! Entries go from "fleeting entries" inbox (not linked or commented on) to "main entries" which spread and connect ideas from across the space.

2. Using yCb as a creator - I created a Google Docs extension and have been using it to create Zettelkasten's for my blogs. On average each blog references 12 or more books. This is a real use case of a PKM system outside doing it for the love of the game [3].

There's so much more including mobile upload, [[links]], audio upload, and more, but you can explore the Notion page in [2] to see the features I've added.

A keyboard that is ergonomic without looking or feeling intimidating (https://github.com/cassiozen/fatbee).

The term "ergonomic" isn't regulated in the US, so the market is full of supposedly "ergonomic" keyboards that offer little real benefits—and in some cases, may actually cause harm.

My main gripe is with split keyboards. The traditional keyboard layout is wrong in so many ways (from the perspective of physiology and biomechanics) that just "splitting in the middle" isn't enough to avoid long-term injury.

Splitting is not wrong, but alone, it's not enough. You need to tackle it from multiple perspectives: Yes, Split the keys, so your wrists aren't bent outward, support the palms so they're not bent upward, and angle the middle part up (like a tent) to keep your forearms from twisting. That twisting is especially bad because it squeezes the carpal tunnel and can lead to nerve and tendon problems.

FatBee is my attempt to incorporate all these elements while creating something that doesn't feel too overwhelming to use.

tatubola3• 2 years ago

As someone who tried (and failed) to adapt to other ergonomic keyboards (like a Microsoft Sculpt a few years ago), this really speaks to me.

The interesting thing is I did manage to fix most of my right wrist pain, but not through an ergo keyboard – switching to an Apple magic trackpad did the trick.

But I'm still intrigued by your design - if it was something I could buy (instead of building) I would give it a go.

dleink4• 2 years ago

I'll first say that is a very pretty device that I would be glad to introduce to my workspace.

This might be outside the scope of your work, but I'm considering going more extreme with ergonomics. What if the keyboard was split and mounted on my chair arms? What possibilities are there with a keyboard on a free-floating arm, whether it's full-sized or several smaller ones? I like that you use the word "familiar", I'm not looking to reinvent how keyboards work, I just want to rethink where I hold my arms.

A concurrent project, I'm working on finding a chair that fits my specific dimensions. I'm too tall for the average chair and have been searching for solutions. Currently, I use a $40 Coleman camping chair that lets me sit at a 135-degree angle with my laptop on my lap and a portable monitor to the side. However, it offers very little support for my head and shoulders, so I'm looking for a chair that can adjust from 90 to 135 degrees and support my frame.

I’ve been working on a free language learning app that uses a local AI model to translate words and sentences. You can read sentences, short stories, or watch YouTube videos with translatable captions. It mostly follows the principles of the comprehensible input theory. Think of it like LingQ, but free and with any language combination.

The main goal is for the app to run entirely on the client side and stay completely free.

Personally, I can’t stand Anki or Duolingo—I’d rather read actual sentences that are fine-tuned to my level.

I'm building an online forms-as-a-service for static websites. I decided recently to revive my personal static site on netlify, where I share out with friends and family my recipes and movie recommendations. I wanted a simple "contact me" form, and decided to scratch my own itch with this service, and build out the server underpinnings so I can iteratively solve more problems static sites may have.

In building out my cheap CI/CD process I wrote a simple web hook utility, using pure python and base libraries, and called it Duct-Tape-Hook: https://github.com/nullfocus/duct-tape-hook/

If this is at all useful or interesting, drop me a line!

in my work, inventory of raw material (computer system, scanner, printer, computer screen) is still done using paper so i'm building this android studio app that uses OCR and sends text to the server that will write it on excel sheet.

the data I want: model, serie, inventory id, type

so I have limited the text output extracted from the image to 4 lines and started each line by the necessary property e.g model: HP prodesk 3000 MT serie: XCQOUNF24 inventory id: to be added manually type: to be choose manually (printer, screen, computer ... )

Inspired by three people, so I tried to find three fitting ways to let people know this story exists. 1: On a website currently showing deep-fake propaganda to support a fascist (felt a bit icky posting there). 2: On a dapp/chain that is the premiere place to lose money on sh*coins (as a sh*coin itself, but at least I'm not going to call it collateral as a pretense for fraud). 3: Here, where they actually managed to get rid of someone (who later proved himself un-rid-able elsewhere).

This is an awesome idea. Traditional use of anki (i.e. med school) is super helpful for memorizing and retaining a vast amount of information making it especially great for recall when solicited on a test or irl. Have you found the ai component to help with learning the meaning of a word or phrase in various contexts?

I’m teaching myself elixir/phoenix by building a SDLC tool inspired by Trac, the simplest tool that ever worked for me. But with CI/CD.

It has morphed in the offing into two tools. One a federated CI/CD tool and one a personal productivity tool with affordances for neurodivergent people.

Atlassian struggles with being a jack of all trades. Bamboo’s integrations make it harder for devs to create repeatable, reliable builds, not easier. I’ve seen Atlassian struggle to scale with dev count so I want something more federated. Jira is in constant danger of becoming a panopticon, using developer’s transparency as a weapon against them at review time, destroying psychological safety. Devs only use these tools if they see personal benefit or are harangued to do so. My thesis is that you need one tool for personal accountability and a separate one for team accountability both to fight Goodhart’s Law and for people with variability in their daily productivity. There are many little tools for doing bits of this but they don’t talk to each other, leaving the plate spinning up to the developer, many of whom plate spinning is onerous.

I’m hoping this will do for bug databases and possibly wikis what interactive rebase does for pull requests. Do what needs to get done, then make it make sense to others afterward.

This is not very concrete, but I've been thinking about the parallels between software development and Factorio and how to tie the two together to be (personally) beneficial. This includes finding ways to make software development as enjoyable as the game* and also pondering ways to make programming more visual. It would be cool to "see" a software project functioning similar to the moving parts of a factory.

* setting small, clear objectives

* spending enough time on refactoring

* giving myself a small reward for completing objectives

* automating more of my repetitive tasks

i'm working on a website to report trail conditions after Hurricane Helene in the Blue Ridge Mountains of Western North Carolina and the Smokys of Eastern Tennessee.

there's a lot of unknowns as trails are still closed and there's not a conditions report feature in strava to use to figure out conditions as they do start opening up.

goals are to have:

- map search for a trail in the region - click the trail, see a popup summary of open/closed, and number of reports on that trail - page for each trail with most recent reports and ~maybe~ pictures - recent reports on any trail on the home page

currently, i'm stuck on full functionality with mapbox directions api and getting the search-for-trail working.

    }
    
    export function someAction(data: Data): Thunk {
        ...
        dispatch(setState(immer.produce(getState(), state => {
            state.lobbyGames[result.data.uuid] = {

Right now, I’m working on a startup with my cofounder called Hypership – an all-in-one platform designed to cut through the chaos of modern web development. After years of building products, I’ve seen how tangled the ecosystem has become. It feels like every tiny feature is another SaaS subscription, with its own login, data silos, and integration headaches. Want error logging? That’s another $20. Need analytics? Another login. And don’t get me started on the documentation for half these tools.

Hypership is our attempt to fix that mess. We’re building a platform where you can deploy, manage, and track everything from one place. No more juggling 15 different tools just to keep your app running. The vision is simple: let devs focus on building great products, not wrangling disconnected micro-SaaS.

Today, kindergarten was closed and I had to take much of the day off to take care of my five-year old daughter. We asked Chat GPT to assume the role of a master board game designer and to lead us through the creation of a novel boardgame, with input from us. She came up with the setting - we are unicorns that need to rescue princes and princesses that have been captured in a scary forest full of monsters. Quickly, the LLM proposed a full list of rules and props to make. We then had fun for around two hours drawing various cards and markers.

The game was playable on the first try with only a few minor and very quick rule tweaks from me. Even I felt we went on a stressful quest in the forest. Honestly among the best games for this age group that I have ever played.

10/10 activity, will try again.

ArduinoCogs. It's a library that adds no-code automation with a web UI, along with a tiny shell interpreter to configure WiFi and back up your settings.

Much like my KaithemAutomation project, you declare "Tag Points" which are like subscribable variables for your IO, then set up state machines that can affect them via the web UI.

I use TinyExpr for the expressions, and a regex to parse command lines. The shell is explicitly not a real programming language, it just allows logicless commands.

TinyExpr bytecode is fast, and other than that it's just raw C++, so there's no inefficient scripting language.

When used with PlatformIO instead of Arduino, it handles power management automatically, getting down to about 1mA with random spikes, as one might expect from the ESP.

But it does support a limited subset of here docs, and an equivalent to the shar command!

All the UI is generated from JSON schemas, and it's designed so you can add new "apps" to the web UI.

The base library includes an MP3 player app, and a FastLed wrapper.

I also have Trouble Codes, to make it easy to add diagnostics and alerts to the system, websocket based real-time dashboards, theme-ability, and there's a Python client (in the iot_devices library) to control devices.

You can configure multiple WiFi networks, and there's a web based file manager.

The two things I really want to add are LCD based UI, so you can actually create your menus and interfaces in the JSON editor, and some kind of mesh protocol backed by OpenDHT, so you could make a device globally visible. I'd also like to have camera and SD card support.

I think it might be a fun "OS" for an ESP32 smartwatch, although it's mostly for Tasmota style use cases.

Nowhere near ready to actually make a proper post , but usable. Kind of. This is pre alpha work.

Eventually I'm hoping it can make Arduino projects a lot easier, by providing all the boring UI and networking stuff so you can just add your core application logic and IO drivers, and get an end user ready customizable system.

Kidz Fun Art (https://kidzfun.art). Three years ago my two kids were 5 and 3 and loved to draw. I tried and tried to find a good iPad app suitable for them but everything I found was full of terrible click bait offensive ads. So, I decided to make them an app myself. It’s been a huge amount of fun, and these days thousands of other people’s kids use it too. I especially love when I get emails from them saying how their 4 year old just saw it and immediately understood how to use it.

Given how much use it’s getting I hope to keep working on it as an active side project for years to come

All of my friends wanted my mom's recipes when they came round for my birthday. Now I realised she doesn't store anything - it's all in her head!

Then the same thing happened with my girlfriend although she writes hers down in a diary (how old school).

And then I noticed so many food influencers posting their recipes in the descriptions of their tiktok/insta posts.

And then as I started searching for recipes online, I found the websites full of ads and popups and terrible UI. I only cared about the ingredients and the method. So I created this, and have been having a lot of fun with it.

I hope to see up and coming food influencers using this as a platform directly to link with their social media posts, engaging and competing with an already interested audience.

Over a weekend last month - at an AI hackathon made https://nonfungibledocs.com

Create variations of your content, so that you can backtrack the source of a leak.

Just changing 5 words in various places of a page of a doc, it can back track 1200 variations. It uses technology from multivariate testing and natural language processing although I have a version that can/avoid using LLMs as well.

## Why Now

With over 1,800 data breaches in the U.S. in 2022 alone, and rising regulatory pressures from GDPR, HIPAA, and CCPA, companies must prioritize information security.

Traditional methods like NDAs and basic data encryption fail to identify the source of leaks, leaving companies vulnerable

The global enterprise data protection SaaS market was valued at $7.9 billion in 2023, expected to grow to $20.1 billion by 2028. Data Loss Prevention (DLP) solutions are set to grow at a 21% CAGR through 2028, while Information Rights Management (IRM) solutions will reach $1.1 billion.

My life is organized between corporate (Outlook), private (GCal) and freelance (various) calendars. Finding a freebusy slot or sharing my accessibility is not easy, and sending someone multiple links makes a little sense. So I figured that I will build calendar processing pipeline that will merge, filter, anonymize, inject, rewrite (etc) calendar events can solve this problem for me. And having all of them merged into a single .ics file is way easier to share, and safer too.

I've been wanting to provide some type of service for a while now. Unique endurance races and endurance challenges recently caught my eye as an area that doesn't have a ton of coverage.

My first idea was to jump right into building a website that made these types of races easily searchable. But I decided to slow down and just figure out the market first by creating a weekly substack newsletter. Each week I'll send out important upcoming dates for various unique endurance events and challenges. If I can grow this substack, I'll put effort into building this into a full fledged website!

The newsletter is call Feat of Strength and here is the latest newsletter: https://featofstrength.substack.com/p/feat-of-strength-newsl...

I am adding more features to my Google Sheets add-on as requested by users. I planned to keep it a micro-SaaS but it seems people want it all at one place. They will pay or not is another thing.

I never finish my books, so I created a small site with concise summaries of books that I want to read. Each summary includes key concepts, critical reception, and recommended related books, along with an audio version for listening on the go. It's still early days with just a few summaries, but I'm enjoying the process of creating them, all by AI with my refined prompts. There are a lot of book summaries out there, but I haven't found one that I like, so I made my own.

I just finished writing a discord bot backed by postgres with a web frontend. Some friends and I like to do watch parties and this system lets you set a theme for a group of movies, everyone submits their picks, then it will randomize and post what the agenda is each week. Afterwards it posts a poll to let them respond with a thumbs up or down. The next thing on my list is to use the voting data to render a user score based on how well their picks were received by the group lol.

I got really interested in this idea when I decided to write it in a stack I don't normally work in, Go + HTMX. Go routines are incredibly useful. I used https://nostalgic-css.github.io/NES.css/ for the front end and it's really become a fun bot all around.

I’m working on https://sweetlemon.app - a tool for tech companies that help them save money on license costs by identifying unused and wasted licenses.

Having worked for 15 years bootstrapping and organically growing digital agencies, I’m now trying to get my own product off the ground.

I’d love to connect with businesses, CTOs, COOs, IT Managers or anyone else who want to talk about trimming down cost in tech companies.

I recently bought a Lotus Elise and have set up a small website to collect most of the things new owners need to know about the car - https://lotus-center.vercel.app/

I'm working on an application. It's really challenging to be a solo developer and build a web application from scratch. I've been working on it for four months now, and to be honest, I've gotten a bit lazy over the past few weeks. But I've decided to launch it before it's completely finished. I'm a perfectionist, which makes things harder, but I know I can do it.

It's barely functional, but I banged away with GitHub CoPilot and managed to put together a BitGrid emulator in React.js[1]

It's wild seeing something I wrote run in a web browser on my phone. I've been doing desktop programs since the 1980s. I've included a link to the GitHub repo[2].
