I started developing a city builder called Metropolis 1998 [1], but wanted to take the genre in new directions, building on top of what modern games have to offer:
- Watch what's happening inside buildings and design your own (optional)
- Change demand to a per-business level
- Bring the pixel art 3D render aesthetic back from the dead (e.g RollerCoaster Tycoon) [2]
I just updated my Steam page with some recent snapshots from my game. Im really happy with how the game is turning out!

[2] The art in my game is hand drawn though
Also working on a language for embedded bare-metal devices with built-in cooperative multitasking.
A lot of embedded projects introduce an RTOS and then end up inheriting the complexity that comes with it. The idea here is to keep the mental model simple: every `[]` block runs independently and automatically yields after each logical line of code.
There is also an event/messaging system:
- Blocks can be triggered by events: `[>event params ...]`
- Blocks can wait for events internally
- Events can also be injected from interrupts
This makes it easy to model embedded systems as independent state machines while still monitoring device state.
Right now it’s mostly an interpreter written in Rust, but it can also emit C code. I’m still experimenting with syntax.
Example:
module WaterTank {
type Direction = UP|DOWN
let direction = UP
let current = 0
[>open_valve direction |> direction]
[>update level |> current]
[
for 0..30 |> iteration {
when direction {
UP -> !update level=current + 1 |> min(100)
DOWN -> !update level=current - 1 |> max(0)
} ~
%'{iteration} {current}'
}
]
[>update level |> when {
0..10 -> %'shallow'
11..15 -> %'good'
16.. -> %'too much!' then !open_valve direction=DOWN
}
]

Honestly I don't know where I'm going with this, but I felt the urge to create it, so here it is.
I learned how to optimize serving assets on CloudFlare.

It just won an award! It was awarded Players' Choice out of 700 daily web games at the Playlin awards: https://playlin.io/news/announcing-the-2025-playlin-awards-w...
Right now around 3,500 people play every day which kind of blows my mind!
It's free, web-based, and responsive. It was inspired by board games and crosswords.
I've been troubleshooting some iOS performance issues, working on user accounts, and getting ready to launch player-submitted puzzles. It's slow going though because I have limited free time and making the puzzles is time consuming!
Here's an article with more info about the award: https://cogconnected.com/2026/03/tiled-words-crowned-the-pla...
Im also building https://www.keepfiled.com, a microsaas to save emails (or email attachments) to google drive
I almost forgot, I also built https://statphone.com - One emergency number that rings your whole family and breaks through DND.
I love building. I built all these for myself. unfortunately I suck at marketing so I barely have customers.
It's an addictive slot machine where I pull the lever and the dials spin as I hope for the sound of a jackpot. 999 out of 1000 winning models do so because of look-ahead bias, which makes them look great but are actually bad models. For example, one didn't convert the time zone from UTC to EST, so five hours of future knowledge got baked into the model. Another used `SELECT DISTINCT`, which chose a value at random during a 0–5 hour window — meaning 0–5 hours of future knowledge got baked in. That one was somehow related to Timescale hypertables.
Now I'm applying the VIX formula to TSLA options trades to see if I can take research papers about trading with VIX and apply them to TSLA.
Whatever the case, I've learned a lot about working with LLM agents and time-series data, and very little about actually trading equities and derivatives.
(I did 100% beat SPY with a train/out-of-sample test, though not by much. I'll likely share it here in a couple weeks. It automates trading on Robinhood, which is pretty cool.)
Pipeline so far has gone like this:
* Use the search engine's API to query a bunch of depravity
* Use qwen3.5 to label the search results and generate training data
* Try to use fasttext to create a fast model
* Get good results in theory but awful results in practice because it picks up weird features
* Yolo implement a small neural net using hand selected input features instead
* Train using fasttext training data
* Do a pretty good job
* for (;;) Apply the model to real a world link database and relabel positive findings with qwen to provide more training data
Currently this is where I'm at
Accuracy: 90.90%
True Positive: 1021
False Positive: 154
True Negative: 2816
False Negative: 230
Precision: 0.8689
Recall: 0.8161
F1: 0.8417
There's a lot of vague middle ground and many of the false positives are arguably just mislabeled.I have been working on it as side project for over two years and now, with funding from the EU for the next 2.5 years, I hope I can make of it a real product for everyone to use that can compete with the likes of Excel and Googl;e Sheets.
I can oly say, I am overly, off the Moon excited
We’ve continued to get some paid customers and have exited beta last week, given everyone seemed to be quite satisfied and there hadn't been requests for changes, only some specific search providers.
Because of bots there isn’t a free trial easily available, but if you’re a human and you’d like to try it for a couple of days for free, reach out with your account number and we’ll set that up!
Thanks.
P.S.: Because people have asked before, our tech stack is intentionally very "boring" (as in, it generates and serves the HTML + bits of JS to enhance settings and such — search can be done without JS), using Deno in the backend (for easier TypeScript), PostgreSQL for the DB, and Docker for easier deploying.
Hister is basically a full text indexer which saves all the visited pages rendered by your browser. It provides a flexible web (and terminal) search interface & query language to explore previously visited content with ease or quickly fall back to traditional search engines.

The front bump out leaks when we get driving rain. I installed some flashing but that wasn't enough, it's still leaking. So I'm working on that so I can close up the big hole in the ceiling some day.
The prior owners filled in the old coal chute with literal bags of cement sort of artistically placed in the hole in the brick foundation. So I'm trying to figure out what masonry tools and skills I'll need to close it up proper.
I'd like to build my kids a playhouse of some sort, sketching out some designs for that.
I'm building a lightweight screen recorder for macOS. It supports lots of features you'd expect from a professional screen recorder such as ProRes 422/4444, HEVC/H.265, and H.264, capturing alpha channels and supports HDR. Frame rates from 24 to 120fps. Can capture system audio and mic simultaneously. You can also exclude specific things from recordings, like the menu bar, dock, or wallpaper.
No tracking, no analytics, no cloud uploads, no account. MIT licensed. Everything stays on your Mac. Still early, but happy to hear feedback!
The stock firmware is horrible but the community has this firmware called CrossPoint. I wanted to be able to upload, manage files etc. from my iPhone on the go and also send over web articles. So I build this app CrossPoint Sync https://crosspointsync.com to do just that.
I've already published it on App Store and pending publishing on Android. The community is niche and has also been using the app, so its been fun building for my use and in turn also getting good feedback from community.
If you are using the Xteink and CrossPoint firmware, then give the app a try.

It worked well enough that the novels were better than the median novel aimed at my son's age group, but I'm pretty sure we can do better.
There are web-based tools to help fiction authors to keep their stories straight: they use some data structures to store details about the world, the characters, the plot, the subplots etc., and how they change during each chapter.
I am trying to make an agent skill that has two parts:
- the SKILL.md that defines the goal (what criteria the novel must satisfy to be complete and good) and the general method
- some other md files that describe different roles (planner, author, editor, lore keeper, plot consistency checker etc.)
- a python file which the agent uses as the interface into the data structure (I want it to have a strong structure, and I don't like the idea of the agent just editing a bunch of json files directly)
For the first few iterations, I'm using cheap models (Gemini Flash ones) to generate the stories, and Opus 4.6 to provide feedback. Once I think the skill is described sufficiently well, I'll use a more powerful model for generation and read the resulting novel myself.
It feels like a small change, but it really makes sense in my brain and I'm glad I finally made it happen. My services feel properly positioned under these distinct brands. Now of course when I get time I need to redesign both of my own websites.
Ideas wise... I like the static website world. I use 11ty, but there are others moving in this direction. Clean, performant, simple html / css / js websites that should last for decades. I like the idea of publishing them to IPFS, creating an indie web with some permanence to it.
We just launched a portfolio for Director of Photography Joel Honeywell: https://joelhoneywell.com/
This is a simple static site, no CMS, built with 11ty.
One of the issues I encountered initially was that the LLMs were repeating a small set of actions and never trying some of the more experimental actions. With a bit of prompt tweaking I was able to get them to branch out a bit, but it still feels like there's a lot of room for improvement on that front. I still haven't figured out how to instill a creative spark for exploration through my prompting skills.
It has been quite exciting to see how quickly a few simple rules can lead to emergent storytelling. One of the actions I added was the ability for the agents to pray to the creator of their world (i.e. me) along with the ability for me to respond in a separate cycle. The first prayer I received was from an agent that decided to wade into a river and kneel, just to offer a moment in stillness. Imagining it is still making me smile.
Unfortunately, I don't have access to enough compute to run a bigger experiment, but I think it would be really interesting to create lots of seed worlds / codebases which exist in a loop. With the twist being that after each cycle the agents can all suggest changes to their world. This would've previously been quite difficult, but I think it could be viable with current agentic programming capabilities. I wonder what a world with different LLM distributions would look like after a few iterations. What kind of worlds would Gemini, Claude, Grok, or ChatGPT create? And what if they're all put in the same world, which ones become the dominant force?
You can either use your own Anthropic/OpenAI key to play, or buy credits. I also have a free non-commercial version on my github you can fork.
Check it out here: https://yoursaga.cc
I also intend to dig into how to integrate Emacs with tools such as yt-dlp and patreon-dl to grab Latin-language audio content from the Internet, transcode the audio with ffmpeg, load it into the LLM's context window, and send it off for transcription. If the essay isn't already too long, I'll demonstrate how to gather forced-alignment data using local models such as wav2vec2-latin so I can play audio snippets of Latin texts directly from a transcription buffer in Emacs. Lastly, I want show how to leverage Gemini to automatically create multimedia flash cards in Org mode using the anki-editor Emacs minor mode for sentence mining.
The result is an experiment called fesh. It works strictly as a deterministic pre-processor pipeline wrapping LZMA (xz). The AI kept identifying "structural entropy boundaries" and instructed me to extract near-branches, normalize jump tables, rewrite .eh_frame DWARF pointers to absolute image bases, delta-encode ELF .rela structs with ZigZag mappings, and force column transpositions before compressing them in separated LZMA channels.
Surprisingly, it actually works. The CI strictly verifies that compression is perfectly reversible (bit-for-bit identity match) across 103 Alpine Linux x86_64 packages. According to the benchmarks, it consistently produces smaller payloads than xz -9e --x86 (XZ BCJ), ZSTD, and Brotli across the board—averaging around 6% smaller than maximum XZ BCJ limits.
I honestly have no idea how much of this is genuinely novel versus standard practices in extreme binary packing (like Crinkler/UPX).
Repo: https://github.com/mohsen1/fesh
For those who know this stuff:
Does this architecture have any actual merits for standard distribution formats, or is this just overfitting the LZMA dictionary to Alpine's compiler outputs? I'd love to hear from people who actually understand compression math.
Supports multiple-accounts (track as a family or even as an advisor), multi-currency, a custom sheet/calculator to operate on your accounts (calculate taxes etc) and much more. Most recently, we added support for benchmarking (create custom dashboards tracking nav and value chart of subsets of your portfolio) and US stocks, etfs etc.

The recent Netflix Games edition of Overcooked with K-Pop Demon Hunters is cool, but not nearly as cool as kids coding and playing their way through Overcooked levels in our custom educational mod for Overcooked:
I'm also maintaining GodotJS, strongly typed TypeScript bindings for Godot, which is used to build the Breaka Club RPG (see first link):
https://github.com/godotjs/GodotJS
And last week I also put together the first release of MoonSharp in ~10 years; Lua runtime for Unity. That's not for Breaka Club though, I also consult for Berserk Games on Tabletop Simulator:
https://milliondollarchat.com a reimagining of the million dollar homepage for the AI age. Not useful, but fun. A free to use chatbot that anyone can influence by adding to the context. The chatbot's "thoughts" are streamed to all visitors.
I have some barebones content at https://struggle-meals.wonger.dev/ and will be working on the design over the next few weeks. Some decisions I'm thinking about:
- balancing between personal convenience and brevity vs being potentially useful for other people. E.g. should I tag everything that's vegan/vegetarian/GF/dairyfree/halal/etc? Should I take pictures of everything? (I'd rather not)
- how simple can I make a recipe without ruining it? E.g. can I omit every measurement? should I separate nice-to-have ingredients from critical ingredients? how do I make that look uncomplicated? (Sometimes the worst thing is having too many options)
- if/how to price things? Depends on region, season, discounts, etc

The silent filter: on cognitive erosion as a quieter, more probable civilizational risk than a catastrophic event
KPT is a language app specifically targeted at explainable verb conjugation for highly inflected/agglutinative languages. Currently works for Finnish, Ukrainian, Welsh, Turkish and Tamil.
These are really hard languages to learn for most speakers of European languages, particularly English - we're not used to complex verb conjugations, they're hard to memorise and the rules often feel quite arbitrary. Every other conjugation practice app just tells you right/wrong with no explanation, which doesn't really help you learn when there are literally hundreds of rules to get right.
The interesting part was using an LLM to create a complete machine-executable set of conjugation rules, which are optimized for human explainability, and an engine to diagnose which rule is at fault when you get it wrong. There's several hundred rules needed for each language in order to cover all exceptions.
NB as a bonus it also works fully offline because my best practice hours are when I'm travelling and have poor connectivity.
I'm still playtesting it with friends and it's been fun. It's in early access, I don't feel right charging for it unless other folks actually end up liking it and thinking it's fun. If you sign up, send me a message through "Send Feedback" (or here!) and let me know if you like, but especially let me know if you hate it.
I recently converted a bunch of stuff to be client side instead of server side (turns out running a real-time MMORPG server is expensive) so there's a new round of bugs I'm still resolving, but it's still fun to play:
const app = new App("com.apple.finder")
and then query for elements: const window = app.$({role: "window"})
const someButton = window.$(/* another query */)
and then do stuff with it: someButton.press()
and you can bind everything to very specific shortcuts like "press and hold cmd, then scroll mouse wheel up"Targeted towards music producers and AI (there's one collection of snippets that starts an MCP server and exposes some basic functionality) in the beginning.
Over the last year I've been hacking on Table Slayer [0] a web tool for projecting DnD maps on purpose built TV-in-table setups. Right now I'm working on making hardware that supports large format touch displays.
Since I also play boardgames, this past month I threw together Counter Slayer [1], which helps you generate STLs for box game inserts.
Both projects are open source and available on GitHub. I've had fun building software for hobbies that are mostly tactile.
I've wanted this for a long time, so I finally started building it. I've had a lot fun!
- Graph-based signal flow: Products become nodes, connections are edges inferred from port compatibility (digital, analog, phono, speaker-level domains)
- Port profile system: Standardized port definitions (direction, domain, connector, channel mode) enable automatic connection inference
- Rule engine: Pluggable rules check completeness, power matching, phono stage requirements, DAC needs, and more
My favorite features are: - custom layout and drag and drop to change window - auto resume to last working session on app starting - notifications - copy and paste images directly to Claude Code/Codex/Gemini CLI - file tree with right click to insert file path to the session directly
OH and it works on both Windows and MacOS! Fully open source too!
It's been a ton of fun to work on. Every subsystem is still flaky so I run into the wackiest bugs imaginable. I'm really grateful for the resources[1] and incredible tooling[2] that enable me to work out my frequent mistakes. I can hardly fathom how Torvalds did this with just his PC running Minix!
No idea how long I'll keep working on it. I think I'd be pretty happy if I got a real-world, non-trivial program running on top of it, but in the meantime it is serving as a good distraction from life worries at least :]

This is the kind of project that creates something from as little as possible, where the only things you need to get started are a very basic RISC-V assembler and a computer or emulator to run it on.
I don't have anything interesting to show yet because I just started yesterday, but one day I will show you.
Give it a try!
It is a pretty fun project
I have a fairly novel approach to operating it, and in the case of one time theft prevention security through obscurity is actually a great approach. The assailant only has a short time to pull the car apart and solve the puzzle, couple that with genuine security techniques, a physical aspect, and it should be pretty foolproof.
It can still be towed away, etc, not much to be done there except brute force physical blocks. Most cars get stolen here to do crime in that night so it's not as common.
It has been a lot of fun to learn about Vulkan / GLSL and the GPU execution model to figure out why the CPU is so much faster than the GPU. I'll be open sourcing the code soon but so far I'm documenting my journey in a series of blog posts. First one of the series is https://www.execfoo.de/blog/deltastep.html
It’s like netflix for language, where users can select/create their personal bilangual stories.
I had quite a lot of feedback from HN, friends, random people on the internet and trying to solve the common pain points and find my way around to make it geniunely useful.
- Most people said it’s hard to come up with a story, so I added url grounding. Also added buttons (including HN :)) so people can just click click and get their stories at their level with their interests.
- Made sure people can generate stories without ever signing up
- Each word is highlighted while being read, and the meanings can be checked with a tap. I also added an option for users to read the sentence for being checked how good their pronounciation is.
- Benchmarked 7 different models to get the fastest & highest quality story generation (it’s gemini now) and it’s insanely fast. I might share more about it on the webpage because I am an engineer and I enjoy this stuff lol.
- Added CSV import in Use my words so Anki users can just import their words to study.
- Also people can download their stories as pdf so they can send it to their kindles.
- I am working on a ChatGPT app, so people can just say “@DuoBook give me a Dutch/English story on latest Iranian events” within ChatGPT, but I am a bit afraid that it might be costly lol.
One thing that I've been very happy with has been "org-people", now on MELPA, which allows contact-management within Emacs via org-mode blocks and properties. It works so well with the native facilities that it's a joy to work on.
I've been learning a lot of new things while I've been expanding it now it has a bigger audience (e.g. "cl-defstruct" was a pleasant surprise).
Why? Many yarncrafters painstakingly build spreadsheets, or try to bend existing general purpose pixel editors to their will. It's time consuming & frustrating.
Along the way, I've solved a bunch of problems:
- Automatic decreases (shapes the hat) / overstitching markers (shows when multiple colors are used in the same row)
- Parameterized designs, like waves, trees, geometric shapes. No more manually moving an object by a couple of pixels, it's a simple click & drag.
- Color palette merging (can't delete a color if you already use it in a pattern!)
- Export to PDF (so you can print it or stick it on a tablet)
- Repeat previews (visualize the pattern as it repeats horizontally)
The core feature that makes this more useful than most general purpose editors is that the canvas is continuous.If you drag a shape near the right edge of the canvas, you'll see it "wrapping around" onto the right edge.
This reflects the 3D reality of a hat!
The most fun is a simple Claude Code in a loop, Boucle, which builds and iterates on its own framework[0][1].
The first thing it built was a persistent memory. Now it has finally built itself a "self-observation engine" after countless nudging attempts. Exploring, probing, and trying to push back the limits of these models is pure chaos, immensely frustrating, but also fun.
Aside from that, some sort of agent harness I guess we call them? Putting together a "system" / "process" with automated reviews to both steer agents, ground them (drift is a huge pain), and somehow ensure consistency while giving them enough leeway to exploit their full capabilities. Nothing ready to share yet, but I feel that without it I’ll just keep teetering on the edge of burnout.
She sells a product with 16 different printed parts, and she prints the parts in bulk batches across 7 different pause points, some of which have pause points for embedding magnets.
The idea is to integrate inventory management and print scheduling into the tool, which will be nice.
I have working so far: * Pulling camera images * Pulling the currently printing file, including the preview image (rendered in bambu studio and bundled with the print; standard for bambu studio), and the pause points * A dashboard with projected timing information * Notifications about jobs starting, stopping & pausing * Remote printer control
Next on the list: * Delayed printing - schedule a print to start in the night. Mostly useful so that if there's a pause point we don't leave a print paused for hours on end. * Print queueing - manually build a list of prints so that after switching plates we can just "next print" for a printer * Print scheduling - select a quantity of print files or groups of files to print, and have it schedule the prints, including projected switch times, to maximize printer utilization by avoiding jobs ending at night * Tracking magnet & filament usage, and integrating BoM and production quantity tracking.
I've been mostly AI coding this, but I've go in to make it extract out components, etc. And I lay down and enforce the DB schema. I've had to ask it to back out a few things entirely. And I've had to give it the Bambu API docs I found github. But it's been going pretty well.
It's like a carfax but for your home, although the intention is more to create an interesting historical narrative that inspires people to care about the history of their home rather than as a tool for inspecting home issues before buying.
My target customer is realtors who want to inspire buyers to take on historic homes that may need a lot of work. Also home owners themselves of course.
I've given myself 6 months
It's a bit scary basically 180ing like this but I figure if I don't try it now I never will
I've already started prototyping various ideas, and to be honest just sitting down and spending time doing this has been really quite lovely
One thing I'm finding fun is slowly unearthing what I actually find interesting
I started with messing around in minecraft and tinkering with rimworld-like game ideas, but I'm slowly moving away from them as I've been tinkering more and more
Don't get me wrong, I do want to revisit them at some point in the future, but I do find myself circling more around narrative, simulations and zachlikes
It's a bit of an odd mix and in some ways they look like paradox style games, but I'm well aware that taking one of those behemoths on is going to be a bit silly, so I'm trying to slim down until I get to a kernel that I actually find enjoyable tinkering with
A toy if you will
Currently I'm trying to work out if there's anything interesting in custom unit design, basically unpicking how games like rollercoaster tycoon's coaster design maps to stats like excitement ratings and seeing how that might mix with old school point buy systems
It feels like it might be small enough to be a good toy and I'm having fun tinkering with it, but I have no idea whether other people will xD
It might honestly be too niche for anyone and I've successfully optimised for an audience of one :shrug:
PS - The results are entirely obvious.

For all the places it's bad at, AI has been fantastic for making targeted data experiences a lot more accessible to build (see MotherDuck and dives, etc), as long as you can keep the actual data access grounded. Years of tableau/looker have atrophied my creativity a bit, trying to get back to having more fun.
https://www.inclusivecolors.com/
The current web tool lets you export to CSS, Tailwind and Figma, and uses HSLuv for the color picker. HSL color pickers that most design tools like Figma use have the very counterintuitive property that the hue and saturation sliders will change the lightness of a color (which then impacts its WCAG contrast), which HSLuv fixes to make it much easier to find accessible color combinations.
I'm working on a Figma plugin version so you can preview colors directly on a Figma design as you make changes. It's tricky shrinking the UI to work inside a small plugin window!
I have no illusions that this is actually something in capable of building to an actual release-able state but it’s fun to tinker with.
The main goal is letting people analyze their games and improve by studying their blunders. It uses stockfish and AI for analysis. You can chat with your games like "Why would I do ___ instead of this?"
Also, there are the standard puzzles and openings type learning with improvement plans.
First release was in December for 1D cuts. Last month I released sheet cutting for 2D cut calculation. It's been working well for my own projects and it started getting consistent daily users since my last update in February. You can save projects now on the site for you to come back to later.
Any feedback is welcome. I'm always looking for what features to add next.

Each game adds more building blocks to the editor: multiplayer, event systems, NPC behaviors, pathfinding, etc. I build a system once, and then anyone using the editor can use it in a click.
Since my last month, I shipped the asset marketplace and the LLM builder. Artists can now upload tilesets and characters, and unlike itch.io, assets drop directly into the editor. You can preview how they'll actually look in-game before using them [1].
An other problem I kept running into: even with a no-code editor, users don't know where to start. So now I'm extending it with a coding agent. Describe the game you want, and it assembles it — pulling assets from the marketplace, wiring up the event system, and using all the building blocks I've spent the past year extracting. Multiplayer, mobile controls, pathfinding, NPC behaviors — the agent doesn't build any of it, just reaches for what's already there.
Once the LLM assembles it, users will have a game ready to work on, and will still be able jump into the editor and tweak everything [2]. Here's an example of what it can already make [3] (after a lot of prompting), and the goal is to reach games like this one I built with the manual editor[4].
Hoping to release the AI mode in a week or two. The manual editor is live at https://craftmygame.com in the meantime.

It's like OpenClaw but actually secure, without access to secrets, with scoped plugin permissions, isolation, etc. I love it, it's been extremely helpful, and pairs really well with a little hardware voice note device I made:
1. Live Kaiwa — real-time Japanese conversation support
I live in a rural farming neighborhood in Japan. Day-to-day Japanese is fine for me, but neighborhood meetings were a completely different level. Fast speech, local dialect, references to people and events from decades ago. I'd leave feeling like I understood maybe 5% of what happened.
So I built a tool for myself to help follow those conversations.
Live Kaiwa transcribes Japanese speech in real time and gives English translations, summaries, and suggested responses while the conversation is happening.
Some technical details:
* Browser microphone streams audio via WebRTC to a server with Kotoba Whisper * Multi-pass transcription: quick first pass, then higher-accuracy re-transcription that replaces earlier text * Each batch of transcript is sent to an LLM that generates translations, summary bullets, and response suggestions * Everything is streamed back to the UI live * Session data stays entirely in the browser — nothing stored server-side

2. Cooperation Cube — a board game that rotates the playing field
Years ago I built a physical board game where players place sticks into a wooden cube to complete patterns on the faces.
The twist: the cube rotates 90° every round, so patterns you're building suddenly become part of someone else's board. It creates a mix of strategy, memory, and semi-cooperative play.
I recently built a digital version.
Game mechanics:
* 4 players drafting cards and placing colored sticks on cube faces * The cube rotates every 4 actions * Players must remember what exists on other faces * Cooperation cards allow two players to coordinate for shared bonuses * Game ends when someone runs out of short sticks

Both projects mostly started as things I wanted to exist for myself. Curious what people think.
The problem was the ML dependencies. The backend uses BGE-small-en-v1.5 for embeddings and FAISS for vector search. Both are C++/Python. Using them from Go means CGO, which means a C toolchain in your build, platform-specific binaries, and the end of go get && go build.
So I wrote both from scratch in pure Go.
goformer (https://www.mikeayles.com/blog/goformer/) loads HuggingFace safetensors directly and runs BERT inference. No ONNX export step, no Python in the build pipeline. It produces embeddings that match the Python reference to cosine similarity > 0.9999. It's 10-50x slower than ONNX Runtime, but for my workload (embed one short query at search time, batch ingest at deploy time) 154ms per embedding is noise.
goformersearch (https://www.mikeayles.com/blog/goformersearch/) is the vector index. Brute-force and HNSW, same interface, swap with one line. I couldn't justify pulling in FAISS for the index sizes I'm dealing with (10k-50k vectors), and the pure Go HNSW searches in under 0.5ms at 50k vectors. Had to settle for HNSW over FAISS's IVF-PQ, but at this scale the recall tradeoff is fine.
The interesting bit was finding the crossover point where HNSW beats brute-force. At 384 dimensions it's around 2,400 vectors. Below that, just scan everything, the graph overhead isn't worth it. I wrote it up with benchmarks against FAISS for reference.
Together they're a zero-dependency semantic search stack. go get both libraries, download a model from HuggingFace, and you have embedding generation + vector search in a single static binary. No Python, no Docker, no CGO.
Is it better than ONNX/FAISS? Heck no. I just did it because I wanted to try out Go.

Basically an API wrapping a cyclic graph where rules govern the state transitions / graph traversal (i.e. rules around handing off work between agents and the associated review, rollback and human intervention escalation logic).
It's mostly just to teach myself about multiagent patterns and what blend of "agentic autonomy" and deterministic / human governance gets the best results with the current set of (Anthropic) tools available.
I don't really know what I'm doing w.r.t AI, but having 15 years of industry SWE experience (high-availability distributed systems and full-stack web dev) on top of a fairly-solid CS education I feel like I know what the results of a working system should be and I'm learning a lot about the AI pieces as I go through trial and error.
Generally it feels like there are lots of ways the next generation of AI-assisted coding workflows could work best (beyond just "AI helps write code", I mean) and the results will be as much about the tooling built around the AI bits as it will be the improvements in models / AI bits themselves (barring a theoretical breakthrough in the space).
Trying to figure out what my personal dev workflow will look like in the middle of this evolving landscape is what led to this project, very much a scratch my own itch thing.
Free Math Sheets is a tool to generate math worksheet PDFs (and the answer keys if required). Currently it supports K-5 but I want to expand it to higher levels of math (Calculus, Physics, you name it!). You select a bunch of different options and then generate it. All in the front-end. No back-end or login in required. https://www.freemathsheets.com
If you are interested in helping out or forking it, here is the github repo github.com/sophikos/free-math-sheets
The paid project is Numerikos. I am going for something in between Khan Academy and Math Academy. I like the playfulness and answer input methods from Khan Academy (but it is linear, doesn't have a good way to go back and practice, etc.). I like Math Academy's algorithm (but it has multiple choice answers, yuck! and is easy to get stuck and doesn't have a good way to explore on your own). Currently Numerikos supports 4th and 5th grade math lessons and practice. The algorithm is based on mastery learning like Numerikos, but you can also see a list of all the skills and practice whatever you want. I am also working on a dashboard system where you can build your own daily/weekly practices for the skills you care about. Next up is 6th grade math and placement tests.
It pulls a list of birds reported on eBird in your county in the last 2 weeks and you ask preselected questions like the the color or size to whittle down the possibilities. I also made a matching game that uses the same list and you have to match the name to a picture of the bird. I set it up for California for now. I wanted to get more comfortable with SQL and APIs.
Feedback welcome.
The first thing I cleaned up was TCL-Edit <https://gitlab.com/siddfinch/tcl-editor>, a small Tcl/Tk text editor I wrote a long time ago. After seeing the Rust clone of Microsoft EDIT, I realized the obvious next step was to build a Tcl/Tk clone of the Rust clone of Microsoft Edit. Recursion shouldn't be limited to code.
I also built a tiny URL system in Perl <https://gitlab.com/siddfinch/perl-tiny-url>, meant to run locally. The idea is simple: short URLs for internal/VPN resources per client. I usually spin up a small daemon (or container) per client and get a dashboard of links I use frequently or recently.
Security is intentionally minimal since it's local, which conveniently lets me ignore authentication and other responsible behavior.
Goal for the year: Continue to open stuff42.tar.gz, pick something, clean it up just enough, and release it, and not have it by the end of the year.
Might even choose a language that might even be described as "modern."
In the past month, as suggested by the previous user, I have added support for kicad schematic libraries. The kicad schematic libraries files are converted into circuitscript format and can be directly imported into circuitscript code. To support the large number of components in the kicad libraries, I had to improve the import functionality and also implement some caching to speed up the imports. With the kicad schematic libraries available now, it provides a larger library of components that can be used in circuitscript projects. The converted libraries can be found here: https://gitlab.com/circuitscript/kicad-libraries
The motivation for creating Circuitscript is to describe schematics in terms of code rather than graphical UIs after using different CAD packages extensively (Allegro, Altium, KiCAD) for work in the past. I wanted to spend more time thinking about the schematic design itself rather than fiddling around with GUIs.
Please check it out and I look forward to your feedback, especially if you are also exploring alternative ways to create schematics. Thanks!
I have built npm for LLM models, which lets you install & run 10,000+ open sourced large language models within seconds. The idea is to make models installable like packages in your code:
llmpm install llama3
llmpm run llama3
You can also package large language models together with your code so projects can reproduce the same setup easily.

We're constantly pulling info from official sources, and using AI to group and summarize into stories, and continue to share reporting from trusted, vetted journalists.
The result is news with the speed and breadth of getting updates straight from the source, and the perspective and context that reporting provides.
Still ramping up, but I'd love to hear feedback:
The problem: AI agents run autonomously, calling LLMs and tools in loops. Without runtime controls, a single agent can burn $50+ in minutes, get stuck in infinite loops, or call dangerous actions without oversight.
What it does: - Cost ceilings — auto-kills when spending exceeds $X - Step limits — prevents runaway execution - Loop detection — catches repeated action patterns - Full telemetry — every step logged with tokens, cost, latency - Dashboard — real-time visibility into all agent runs
One decorator. That's it: @guard(max_cost_usd=10, max_steps=50) def run_agent(): agent.run()
Stack: Python SDK, TypeScript SDK, FastAPI backend, Next.js dashboard
Links: - GitHub: https://github.com/vijaym2k6/SteerPlane - PyPI: pip install steerplane - npm: npm install steerplane
Currently building: policy engine (allow/deny actions), remote kill switch, and framework integrations.
Would love feedback from anyone running AI agents in production! What controls do you wish you had?
The interesting part is that it’s not just about adding another database driver. I’m revisiting a big part of the codebase and introducing a framework that should make implementing support for new DBMSs much simpler. The goal is to make Greenmask more extensible so that the community can add support for other databases without needing to dig through the entire internal architecture.
Published the first beta of this new approach a few months ago, and now the focus is on stabilizing it and making it production-ready.

Primarily to use in conjunction with OpenVPN. Like secretive or /usr/lib/ssh-keychain.dylib[2], but not just for SSH.
Opus has been amazingly useful at answering various statistics question that I had for it, and my current idea is a nested auction market theory inspired model. My biggest discovery is that replacing time with volume on the x axis (on a chart) and putting the bar duration on the bottom panel instead of volume normalizes the price movements and makes some of the profitable setups I've seen described in tape reading/price ladder trading courses actually visible on naked charts. A great insight I've gleamed is that variance should be proportional to volume instead of time or trade count. When plotted, it has the effect of expanding high volume areas, and compressing low volatility ones, which exposes trending price action much more readily. It honestly amazing, it's making me think that I could actually win at the trading game.
The system allows users to submit a JSON payload containing geocoordinates and mission requirements (e.g., capture_type: "4K_video" | "IR_photo"), the backend then handles the fleet logistics, selecting the optimal VTOL units from distributed sub-stations based on battery state-of-charge and proximity.

I've been building a collaborative docs tool called Docules. The short version: it's a team documentation tool that doesn't have any embedded AI features. I use Claude Code daily, but putting LLMs into every workflow and charging for it is kinda insane. Every docs tool is adding AI auto-complete, AI summaries, "generate a page" buttons. Docules has an API and an MCP server instead, so you connect whatever AI tools you actually want to use. The core product focuses on being a fast, solid docs tool. Real-time collab, fast — no embedded databases or heavy view abstractions, hierarchical docs, drag-and-drop, semantic search, comments, version history, public sharing, SSO, RBAC, audit logs, webhooks, etc. The stack is React, Hono, PostgreSQL, WebSockets. The MCP server is a separate package that exposes search, document CRUD, and comments — so Claude/ChatGPT can work with your docs without us reimplementing a worse version of what they already do. Happy to talk architecture or the MCP integration.
I posted about it recently on HN (https://news.ycombinator.com/item?id=47199062):
It is at a fairly early stage of development, so it's quite rough around the edges. It is developed and hosted in EU.
I have started developing it as a slim wrapper around Git to serve my own code, but it grew to such extent that I decided to give it a try and offer it as a service. It doesn't have much at the moment, but it already has basic pull requests. Accessibility is high priority.
It will be a paid service, (free for contributors) but since it's an early start, an "early adopter discount" is applied – 6 months for free. No card details required.
I would be happy if you give it a try and let me know what do you think, and perhaps share what you lack in existing solutions that you would like to see implemented here.
It's an auction website for schools, charities etc without the exploitative transaction fees.
My wife and I are pretty heavily involved in our son's school PTA (parent teacher association) and have helped run school fundraising events for a few years, so we feel sort of like domain experts in this area :)
Platform-aware script runner for Node.js projects.
pnpm add -D target-run
Set a script body to `target-run`, then define platform/arch variants: {
"scripts": {
"test": "target-run",
"test:darwin:arm64": "jest --config jest.apple-silicon.config.ts",
"test:linux:x64": "jest --config jest.linux.config.ts",
"test:default": "jest"
}
}Separately I've been dipping my toes in to hosting things on the Scary Public Internet with an IRC server (as a backup/replacement for a personal Discord server) and a static Hugo website (for hosting fanfiction; there've been a few AO3 outages lately and I thought it would be fun to experiment with things like audio embeds). I'm a roboticist so my experience with webdev is pretty minimal, but I managed to figure out nginx eventually. I'm actually kind of frustrated with Hugo as an SSG because it really doesn't want you to run pandoc with custom arguments for markdown -> html conversion, and pandoc doesn't want to generate ToC on my markdown files, but the default markdown converter (goldmark) doesn't correctly process markdown italics inside of html tags (e.g. `<center>`), so my current compromise is to use pandoc on almost everything and goldmark anywhere I care about having a ToC.
I started small as a toy project, but gradually implemented full support for proper block context, flexbox layout, CSS variables, tables, etc. to the point where I have almost full support of all major CSS features (even math functions like calc(), min(), max()).
I'm cleaning up the code right now and will upload it later today or maybe tomorrow here: https://github.com/PureGoPDF
Started it because I wanted to develop from my phone while working on another project (Siteboon, a website builder). Open-sourced it last June and wasn't paying much attention. Looked up a few months later and it had a couple thousand stars. Now at 8.2k.
The interesting moment was when Anthropic launched Remote Control. Stars went up instead of down because their launch validated the use case but only lets you view and approve sessions, not fully control your instance. We went from 6.5k to 8.2k in a couple of weeks.
The other project I am continuing to work on is Rad [1], a programming language tailor made for writing CLI scripts. It's not for enterprise software, it specializes specifically in CLI, offering all the essentials built-in, such as a declarative approach to arguments and generated help (as opposed to Bash where you have to roll your own arg parsing and help strings each time).
As many here, I've found that a single text file is all that I really need, but found that it makes it difficult to keep track of a variety of things. I was also trying to use the file as a simple project tracker, adding some tags like [BUG-N], and updating them by hand. Eventually, it became difficult to track the progress of things, since I had to jump around the file to look for updates.. or use grep.
I condensed the idea to just that - a very simple tool which manages "trackers", and has a simple filtering built in to "trace" the updates. I've been using it, since I've added the BE, and dogfooding it a bunch. Would love for fellow note takers to take a look. It's not perfect, but I'm keeping it around for myself :)
At this moment I’m working on improving the logic that decides when/how much to throttle the network.
Built it because I wanted to read more, but most reading apps either feel too passive or turn everything into social noise. What worked better for me was making reading easy to start: short 5–10 min sessions, pick up where you left off, minimal friction.
So the app is basically centered around habit formation, with stuff like notes, progress tracking, session extension, shelves, and simple organization.
I care a lot about keeping it quiet: no ads, no feed, no unnecessary clutter.
Still early. Mostly trying to understand what actually helps people read more consistently.
Currently only available for iOS, but might release an android version in the future.

A lot of existing databases are storage first, with everything else built around them. I have been exploring what it looks like if the database is closer to the application runtime itself, where state is live, queryable, and easier to reason about directly.
One thing I am prototyping right now is database-native tests.
Basically: what if integration tests were a database primitive?
CREATE TEST test::insert { INSERT test::users [{ id: 99, name: "Ghost" }]; FROM test::users | FILTER id == 99 | ASSERT { name == "Ghost" }; };
So not a wrapper, not a framework, not an external test runner.
A real test object inside the database.
The idea is that you could run these before schema changes, and make stored procedures or other database logic much easier to test without leaving the database model.
Still early, but it feels like one of those things that should just exist, especially for databases built around live application state.
The problem: every agent (Cline, Aider, Codex, Claude Code) has unrestricted access to your filesystem, shell, and network. When they process untrusted content — a cloned repo, a dependency README — they’re prompt injection vectors with full machine access. No existing tool evaluates what the agent actually does at the syscall level.
grith wraps any CLI agent without modification. OS-level interception captures every file open, network call, and process spawn, then runs it through 17 independent security filters in parallel across three phases (~15ms total). Composite score routes each call: auto-allow, auto-deny, or queue for async review. Most will auto approve - which eliminates approval fatigue.
Also does per-session cost tracking and audit trails as a side effect of intercepting everything.
Provisional patents went in recently so don't mind broadcasting to a wider audience beyond my poor, unknowing, testers
You can see it working here: https://www.youtube.com/watch?v=G5Xup3kB1D0 and I literally put up a holding page for some media related surges (as it's all self hosted etc and I didn't want to mix my functional stuff with my spikey stuff) here ( name to be worked on, but "NUTS" is the current one) : https://buttonsqueeze.com
I have worked with data for a while. I feel like our tools could be much better when it comes to "flow". I want an experience where you don't need to alt+tab to slack/images/another query. What if we put it all on a canvas? That's what Kavla is all about!
Since last month I've done a lot of improvements to the editor to make the "flow" better.
I've also read up on HMAC, Nonces and fun encryption stuff to create read only boards.
Here's one where I look at stack overflow survey for databases: https://app.kavla.dev/v/mqhg54o319doya4.67dbfee1ccd6caf638d3...
Snowflake users apparently make the most money!
- chef personalities generating interesting recipes every couple days
- the ability to save and edit these recipes to suit your needs/ingredients
- the ability to schedule weekly meal plan generations that take the inspiration content and give you a plan and shopping list for the week.
We had our first kid this year and I've been having more trouble getting things together for home cooked meals. This is my attempt to make it is frictionless as possible. I'm working on getting instacart API access so I can build out the cart for the meal plan automatically, at which point I'm hoping this is a one click confirmation a week to keep interesting food flowing. Works great for scheduling baby meals as well!

I built a service that lets developers bundle remote files into a ZIP with a single POST request. You send a list of URLs, we fetch, package, and return a signed download link.
The problem: creating ZIPs from remote files (S3, R2, CDN) usually means downloading to a server, zipping locally, managing temp storage, and cleaning up. It's surprisingly painful at scale — especially with large files or thousands of items.
Eazip handles all of that. ZIP64 support for files over 4GB, up to 5,000 files per job, zero egress fees on downloads, and no infrastructure to manage.
Use cases so far: e-commerce photo bundles, document delivery (invoices/contracts), creative asset distribution, and backup/export tooling.
Free tier available, no credit card required. Would love feedback from the HN community.
This is a "full rewrite," because I need to migrate away from my previous server, which was developed as a high-security, general-purpose application server, and is way overkill for this app.
Migration is likely to take a couple more years, but this is a big first step.
I've rewritten the server, to present a much smaller API. Unfortunately, I'm not yet ready to change the server SQL schema yet, so "behind the curtain" is still pretty hairy. Once the new API and client app are stable, I'll look at the SQL schema. The whole deal is to not interfere with the many users of the app.
I should note that I never would have tried this, without the help of an LLM. It has been invaluable. The development speed is pretty crazy.
Still a lot of work ahead, but the server is done, and I'm a good part of the way through the client communication SDK.
Built with React Native/Expo. The hardest part hasn't been the sensor code, but rather designing interactions that feel natural rather than gimmicky. Each word needs to map to a physical action that actually reinforces the meaning. Solo dev, live in German app stores now. Previously co-founded another language learning startup (Sylby, partnered with Goethe Institute), so this is take two with a very different approach.
Right now, actively building and growing https://OpenScout.so which is a tool for tracking mentions on Reddit, Linkedin, Twitter and HN. This is primarily made for early stage SaaS founders to help them with brand visibility problem.
Also, I don't support bots so we will never built bot solutions. This is against most of the ToS of platforms. I started this because I truly realised that building has commoditised and the go to market is the real deal. This tool helps with that. I'm going to add more features and I would love for you to try it.
An important feature for me was improving the recipe discovery experience, you can build a cookbook from chefs you follow on socials (youtube for now), or import from any source (Web, or take pic of cookbook etc) - it then has tight / easy integration into recipe lists.
Utilising GenAI to auto extract recipes, manage conversions, merge/categorise shopping lists etc - as-well as the actual recommendations engine.
If anyone is interested in beta testing / wants to have a chat I'll look out for replies, or message mealplannr@tomyeoman.dev
I wrote a CLI utility last year to control my SoundBlasterx G6 DAC (can only control LED colour and EQ bands) without needing to use Creative's windows only program (I am mostly a Mac + occasional Linux) user.
Recently downloaded Qwen3-coder-next 80b model and been vibing with it to introduce Qt6 and write a dead simple (aka ugly) crossplatform GUI to it so that other people can use it on their Macs and Linux machines. Letting a LLM wreak havoc on your project feels bad, I constantly have to reign it in and rollback the repo once it starts looping due to writing something that doesn't compile, making it going back and forth between doing and undoing changes.
Basically OpenClaw but with investing dashboards for my portfolio, additional tools specifically for investing, and exploring an AI-Human collaboration on researching economics (check the 'community' tab).
The data models are all in markdown and Excel so that there's no lockin and you can manually edit positions, personalities, etc.
This comes from frustration around most investing tools basically scraping your personal data + forcing you to lock into subscriptions. I think it's now possible to just vibe code most of what one needs, aside form raw data subscriptions.
It's all open source, too: https://github.com/wgryc/athena-os
The basic idea is that an utterance often has a gap between its surface form and its actual function in context. For example, a sentence like “Do you know what time it is?” may look like a question, but pragmatically function as criticism, pressure, or a prompt for reflection.
Mimesis tries to represent an utterance not just as text, but as a structured object with separate layers for: - `core`: semantic meaning and emotion - `will`: communicative purpose and influence - `flow`: discourse framing / progression - `exp`: surface realization
I’ve put together: - an English/Korean whitepaper - a schema spec - a working interactive demo
Still early, but I’m interested in whether something like this is useful as an intermediate representation layer for LLM systems, agent workflows, or discourse analysis.

Currently my mini-projects includes:
* 0% USA dependency, aim is 100% EU. Currently still using AWS SES for email-sending and GCP KMS for customer data key encryption for envelope encryption.
* Tool output compression, inspired by https://news.ycombinator.com/item?id=47193064 Added semantic search on top of this using a local model running on Hetzner. Next phase is making the entire chain envelop encrypted.
* "Firewall" for tool calls
* AI Sandboxes ("OpenClaw but secure") with the credential integration mentiond above
Currently adding support for exposing Postgres schemas for each app to use. The goal is that with a shared Postgres instance, each app should be able to either get a dedicated schema or get limited/full access to another app's schema, with row level security rules being supported.
Most monitoring tools alert every time anything changes. That usually ends up being navigation tweaks or small copy edits. After a while the alerts just get ignored.
Adversa focuses on meaningful updates instead. It detects changes across competitor pages and uses AI to summarise what changed and why it might matter.
I originally built it because I was manually checking competitor pricing pages and changelogs. I also wanted something practical for smaller SaaS teams. A lot of existing tools are either enterprise-priced or the free tiers are too limited to be useful.
Still early and trying to learn what people actually want from this kind of tool.
It started because my wife watches Chinese dramas and new episodes never have subtitles for our language. Turns out thousands of people have the same problem — Arabic speakers watching anime, Russian speakers following Turkish series, Persian speakers catching up on K-dramas.
Supports 40+ languages, works with any video link or direct file upload. There's also a Mini App inside Telegram for a more visual experience.
Here are the current features - Closet — Add clothing items with photos, category, color, brand, and tags. Visual wardrobe with hanging rod and shelves for browsing by category - Worn / Hamper tracking — Mark items as Clean, Worn, or in the Hamper to track what needs washing - Outfits — Build and save multi-piece outfits, organized by occasion - Weekly Schedule — Assign saved outfits to days of the week - AI Stylist — Get outfit suggestions powered by DeepSeek AI, with live weather integration - Preferences — Set style profile, favorite/avoid colors, occasions, and custom styles - Onboarding — First-launch questionnaire to seed your closet with basic wardrobe pieces
I'm still awaiting approval from Google Play and Apple. I'd love to hear what kind of features y'all would want in an outfit organizer app too.
I was sick of getting cross-eyed when looking at tables in raw markdown and was just running it locally. This weekend I realized it might be useful for others.
The goal was simple as possible UX. Open url, drag and drop or paste into wysiwyg -> very readable and editable markdown. No sign up, no tracking, no fuss.
Of note, if you copy from the richtext mode, it copies raw markdown. The inverse is done with paste.
Based on feedback, I am working on very optional cloud-sync for as cheap as I can make it.
If you’ve used H3 the semantics should be familiar. The biggest differentiator is the fact that cells have exactly the same area globally, for why this matters see: https://a5geo.org/docs/recipes/a5-vs-h3
Since starting the project last year and providing implementations in TypeScript, Python and Rust it’s been great to see a community grow, porting or integrating into DuckDB, QGIS and many more: https://a5geo.org/docs/ecosystem
The idea is pretty simple: SQLite is amazing, but once it’s running in production you basically have zero observability. If something weird happens (unexpected writes, schema changes, background jobs touching tables, etc.) you only find out after the fact. It tries to solve that without touching application code. It's a Rust agent that runs next to your sqlite file, and connects to the server where everything is logged in. My current challenge right now is encryption and trust, mostly.
Curious if others here are running SQLite in production and if you would be interested in something like this.

The idea is: you join a meeting, hit start on the app, minimize, and go do actual work (or go make a coffee). When someone says your name or any keyword(s) you set, you get a native macOS notification with enough context to jump back in without looking lost. It uses whisper and is 100% local and doesnt leave traces, also very OE friendly.
Would love to hear what you think, especially if you're drowning in meetings too.
Also used the new Navigation API (and some Shadow DOM) to build a cheap, custom client-side rendering (sort of) into my site (https://taro.codes), and some other minor refactors and cleanup (finally migrated away from Sass to just native CSS, improved encapsulation of some things with Shadow roots, etc).
I've been wanting to write a simple AI agent with JS and Ollama just for fun and learning, but haven't started, yet...
I started it after an AI coding agent destroyed my SQLite database mid-session for the third time. Git doesn't back up databases, and it shouldn't. But nothing else was doing it either.
It runs silently in the background and watches your project, detects changes, backs up to encrypted cloud storage (Dropbox, Google Drive, OneDrive, iCloud). Supports SQLite, PostgreSQL, MySQL, MongoDB. Has a native macOS menu bar dashboard.
Free and open source. v2.7.0

To date it's handled more than 70k orders, ingested nearly 10m telemetry records, has been extremely reliable, is almost entirely self-contained (including the routing stack so no expensive mapping dependencies) and is very efficient on system resources.
It handles everything from real-time driver tracking, public order tracking links, finding suitable drivers for orders, batch push notifications for automatic order assignment, etc.

The insight: the friction in getting testimonials isn't that clients don't want to help – it's that a blank "leave a review" box produces mediocre one-liners. SocialProof guides them through structured questions ("what was your situation before?" / "what changed?") so you get a compelling before/after narrative automatically.
Free tier: unlimited testimonials. Just launched and looking for feedback from anyone who deals with client testimonials.

- Versioned, deduplicated symbols with multi-contributor collaboration
https://github.com/nickbarth/closedbots/ I was also trying to do a simplified openclaw type gui using codex. The idea being its just desktop automation, but running through codex by sending codex screenshots and asking it to complete the steps in your automation via clicks and keypresses via robotgo.
Some of these are present here: https://github.com/vamsipavanmahesh/claude-skills/
Planning to package this as a workshop, so companies could be benefit from AI Native SDLC.
Put together the site yesterday https://getainative.com
Couple of the people I have worked with in the past agreed to meet me for a coffee, will pitch this. Fingers crossed.
I think the first step is standardizing HTTP 402 using traditional, familiar payment rails like Stripe, then we can move to things like on-chain or other rails later.
I am building https://stripe402.com to try to make it dead simple for those building APIs/resources to get paid per request through stripe without user's needing to sign up for accounts, get API keys, any of that normal painful workflow required today.
Check it out and feedback welcome!
A fun simulation game of prod breaking where you have to race to troubleshoot and fix the issue. Great for SREs, devs devops, founders and teams to learn in a non prod environment but feels real.
We are in beta and would love feedback!
Was on show hm the other day https://news.ycombinator.com/item?id=47323915
I was stuck on this conversation problem. First version had a dead-end search box: six starter prompts, one referencing a tool that didn't exist. No follow-ups. No guided flows. Users got an answer and had to invent the next question from scratch.
Now the assistant explores your library with you. Tag discovery, color browsing, weekly digests, smart collections that auto-curate as you save.
Semantic search runs hybrid, keyword matching plus pgvector cosine similarity on 768-dim embeddings. Streaming responses.
Almost there. https://bookmarker.cc/
Example: https://progressbars.dev/400x40/3/10
https://housepricedashboard.co.uk - shows a visualisation of house prices in England and Wales since the 90s, with filters for house types, real vs nominal, and change views over time
https://councilatlas.co.uk - similar structure to the above, but focusing on local council datasets. The idea is to make it easier to compare your local council's performance against the rest of the country.
Picked up some more small Xilinx Zynq 7020 dev boards for a quick micro-positioning vacuum-stage control driver. Yeah it was lazy, but I don't have time to spin a custom PCB board these days... or hand optimize LUT counts to fit smaller prototypes.
Also, doing a few small RF projects most people would find boring. =3
Locally running fully working steganography in the browser.
Create and insert entire files into pngs, mp4, pdfs and jpgs. The site is a static website that loads a wasm bin that does everything in browser with wasm. So no login, or network calls.
Essentially impregnate images and videos that open normally in your browser, but have a full file system with a full gallery mode for images, pdfs and images inside. videos do seek and stream so even if you embed a 4GB video file, it opens quite fast and just works.
Current Status: All 8 core smart contract features are complete — 60 tests passing. Ready for Sepolia testnet deployment to validate the full system on-chain before mainnet.
Motto: "Paradise by Code"
Now shifting to established SaaS companies adding AI assistants to their existing products. Some of them literally have people reading chats full time, so they actually value the experience.
Building https://lenzy.ai - 2 paid customers, 2 pilots, looking for more and figuring out positioning.
The core is pure JavaScript with zero dependencies. It works in Lab color space (not RGB) using Wu quantization, CIE perceptual distance metrics, and a DNA fingerprinting system that matches each image to one of 20+ built-in archetypes (Golden Hour, Dark Portrait, Fine Art Scan, etc.).
There's a browser-based web UI that just needs Node.js — drop an image, get 4 different possible separations side by side, export as layered OpenRaster (for GIMP/Krita), or flat PNG, or layered PSD (for Photoshop). There's also a CLI and Photoshop plugin.

This project makes use of existing database infrastructure and parses data from multiple banks including caveats and quirks of some banks improper handling of data.
This project aims to ease the work of accountants and administration as currently a lot of correcting mistakes and pairing to the correct invoice is done manually.
The project is made in python however the modularity we set ourselves to implement allows for quick, easy and hassle free corrections of code with use of project schematics, like builders, dependency injections etc. Discovered a great tool for running tests efficiently https://docs.astral.sh/uv/ .
Also for data retrieval from a remotely located database. DO NOT USE pyodbc, USE mssql library. pyodbc is unoptimized in terms of receiving high amounts of streamed data, it can't keep up. That alone has dropped the time of execution from 18 minutes down to about 20 seconds.
Also making use of typer and data classes for ensuring correct types of data.
It already runs pretty smoothly. Next steps are adding a way to make playlists and listen to them right there, without leaving the page. Check it out and let me know what you think! All feedback is appreciated!
Once I'm done with this project I'm planning on making a series of YouTube videos going into the code and the algorithms.
I'm also publishing a hackernews daily digest.
This story was included in the March 9th issue (https://hn.alcazarsec.com/daily?date=2026-03-09).
Hacker News users are currently developing a diverse range of projects, from a retro-inspired city builder game [0] and an award-winning daily word puzzle [4] to a European-based search engine alternative [2] and a NSFW filter for the Marginalia search engine [8]. Several developers are focusing on practical tools for family and personal life, including an educational site to help relatives identify AI-generated content [1], a "statphone" for emergency family alerts [3], and a local-first financial tracking app using double-entry accounting [6]. Others are experimenting with advanced technical implementations, such as using LLM agents to backtest stock trading strategies [5], "vibe-coding" CLI tools, and designing a new language for bare-metal embedded devices [7].It's designed to integrate with Maven projects, to bring in the benefits of tools like Gradle and Bazel, where local and remote builds and tests share the same cache, and builds and tests are distributed over many machines. Cache hits greatly speed up large project builds, while also making it more reliable, since you're not potentially getting flaky test failures in your otherwise identical builds.
Managing our above ground pool this summer and small hot tub in winter and continually asking "why isn't this easier" led to the development of Pool Pilot. Scan a test strip with your camera, water care recommendation checklist generates and you can order more supplies if needed easily from Amazon. Basically met my personal need and hoping it will help others too.
The fun technical bit: test strip chart colors can vary by manufacturer and even between production batches, but, the specific color chart that comes on a bottle should be accurate to those specific steps. Additionally, test strip colors are notoriously hard to match from photos. RGB comparison falls apart with lighting changes. After many interesting and considerations we calibrate of the specific test strip bottle and we use LAB color space and Anthropic's Claude vision model to read strips directly. This has worked exceptionally well in our testing and works with any brand;
The app also offers timers, history and much more. It has become a minor obsession.
React Native/Expo, Firebase backend, $10/year after 3 free tests (early tier pricing). Would love feedback from any fellow pool or hot tub owners.
This was an excuse to ship a mobile app for the first time and get familiar with supabase.
After these last few bugs are fixed, its ready for a semi-public TestFlight with our friends who have kids.
I've been building a collaborative docs tool called Docules. The short version: it's a team documentation tool that doesn't have any embedded AI features. I use Claude code daily, but putting LLM’s into every workflow and charging for it is kinda insane. Every docs tool is adding AI auto-complete, AI summaries, "generate a page" buttons. Docules has an open API and ships an MCP server, so it connects to whatever you want to use LLM-wise. They can read, search, create, and edit documents through the API. The core product is just a docs tool that tries to be good at being a docs tool:
- Real-time collab with live cursors
- Fast — no embedded databases or heavy view abstractions slowing things down
- Hierarchical docs, drag-and-drop, semantic search
- Comments, version history, public sharing
- SSO, RBAC, audit logs, webhooks
Stack is React, Hono, PostgreSQL, WebSockets. The MCP server is a separate package so it's not coupled to the main app. I keep seeing docs tools bolt on half-baked AI features and call it innovation. I'd rather build a solid foundation and let you plug in whatever AI workflow actually makes sense for your team. Happy to answer questions about the architecture or the MCP integration.Also been spending some time on my old side project https://infrabase.ai, an directory of AI infra related tools. Redesigned the landscape page (https://infrabase.ai/landscape), going through product submissions and content, optimizing a bit for seo/geo.
Models are the new software. And just like software, three general-purpose ones won't be enough. Why specialized models are inevitable https://mixtrain.ai/blog/special-models
Here's how Mixtrain can help:
- Multimodal dataset management: version, query, inspect, and curate image/video/3D datasets
- Workflows & models: train and run your models on serverless GPUs. Run experiments rapidly and ship to production. Access 100s of external models through the same API.
- Live eval: create instant evals from your datasets with side-by-side comparison of anything — images, time-synced video, 3D/4D visualizations, masks, and more. Here's an example video eval https://app.mixtrain.ai/s/eVRwOcb7KhUZOb9xbFFgfHIuF0jyJUaBT6TKNg19OfU. Evals stay current as your datasets evolve.
You can explore more at https://mixtrain.ai/docsThe filtering was easy, but RSS doesn't do "from the beginning" (RFC 5005 exists, but is mostly unused), so scope crept into a webpage-to-RSS tool that lets me convert favorite.site/s/archive - autodetection of the article structure was a fun side quest.
The whole thing is a little function engine (Yahoo Pipes called), so the final goal is `merge(archive, live_feed) | drip(N items per D days)` to have the archive transition seamlessly into current content. I expect I can push that live tomorrow or so.
And of course Podcasts are just RSS, so hey, let's skip reruns. That's doable with filters on the episode description, but with history in place I'll add title similarity checking. I'm trying to think how to recognize cross-promoted episodes too, without having to crawl every podcast.
Importantly, Sponder's _not_ a client. There are enough clients, any many are great. Each implements some subset of features, so Sponder's an intermediary that consumes and publishes pure RSS for us to use anywhere we want.
Project two started over the weekend and is the NYTimes' Pips, but colors. You're building a stained glass window with regional constraints, and the big difference from using dominos is colors can mix. Also, triangles! The engine works, and I'm designing the tutorial and first handful of puzzles now.
So I started by adding the ability to define syllable structure in the rules file, then I tried running the syllable rule through the same compiler I used for the regular sound change rules. It ended up being even slower than I was anticipating, so I decided to skip the NFA to DFA conversion step and wrote a backtracking NFA runner. This worked _okay_, but if the syllable rule isn't able to fully match a word it ends up backtracking forever, and I never managed to figure out how to fix that.
Last year I read a post about parser combinators and I decided to rewrite the syllable detector. I finished the rewrite and then ran into an error and gave up. This last weekend I revisited it and it turned out it was just user error again; my syllable definition rule had a mistake, but thankfully the error was a lot easier to fix with the new design. Now it emits a warning, and I'm rewriting my sample sound changes rules to use the new boundary markers and hammering out any issues, which are a lot less than I was afraid of.
I'm thinking about rewriting the sound change rule compiler to use the same combinators I did for the syllable rules, but it would be kind of a shame after all the work I put into the DFA compiler lol
The core pipeline: AI generates structured quote pages → automated image synthesis with custom JSON templates (typography, gradients, layout) → Pinterest distribution for social traffic alongside Google SEO.
Currently in English traffic validation phase. Interesting challenge has been tuning the image generation — switching from monospace to serif fonts made a surprisingly big visual difference. Also figuring out the right balance between AI-generated content volume and quality signals Google actually cares about.
Next steps: Spanish/Portuguese expansion, then launching inspirationalquotes.app as a paid AI quote image tool for social media managers and HR teams.
Happy to discuss AI content site architecture or Pinterest SEO if anyone's been down this road. https://motivational-quotes.net

It's mainly for censorship evasion (should be much harder to block than the regular centralized VPNs), but also for expats to access geo-blocked domestic services.
It's at the MVP stage and honestly it evoked much less interest in people than I hoped it would, but I'm still going on despite my better judgement.
But anyway, I've started to learn Go. By doing a vertical scrolling shooter with embiten. Kinda like fitting a square peg into a round hole. No, it's not public and will probably never be.
Studying how do do a memory pool for actors, since it doesn't look like garbage collection and hundreds of short lived bullet objects will mix well.
The idea came from trying to find a neat screenshot app on Linux for taking and sharing screenshots for another SaaS I'm working on: LanguagePuppy [2], but I couldn't find one that worked. So I rolled up my sleeves and started to make my own using Clojure.
The main features are: 1. Taking screenshots 2. Adding padding, shadow, and rounded corners to the screenshot 3. Adding background 4. Choosing the right ratio for your target social media 5. Adding watermark 6. And more
Eventually, it should work on Linux, Windows, and macOS when I launch.
P.S. I am building both with Clojure, a functional programming language, and Lisp.
So far, I think it is in fact worth it, but only in specific use cases, like very rarely accessed items with no obvious place, and making sure your AV gear you bring to events comes back with you.
* Every item is a container, unlimited nesting
* Everything stored in the browser with YJS, very clunky peer.js or manual file sync available
* Select an object, click add items, scan QR codes to add those items
* There's also NFC support on Chrome mobile
* Generate random printable QR sheets(Still need to fix sticker alignment issues)
* Tracks where an item was last scanned with GPS
* Save container contents as a loadout, check contents against loadout
* Can mark a container as needing re-inventory, contents that haven't been re-added after that show a warning
But once all the low level operations are done, my plan is to implement an A2A Agent as the sole Agent listed in the AgentCard at $SERVER_ROOT/.well-known/agent-card.json, which is itself an "AgentListerAgent". So you can send messages to that Agent to receive details about all the registered Agents. Keeps everything pure A2A and works around the point that (at least in the current version) A2A doesn't have any direct support for the notion of putting multiple Agents on the same server (without using different ports). There are proposals out there to modify the spec to support that kind of scenario directly, but for my money, just having an AgentListerAgent as the "root" Agent should work fine.
Next steps will include automatically defining routes in a proxy server (APISIX?) to route traffic to the Agent container. And I think I'll probably add support for Agents beyond just A2A based Agents.
And of course the basic idea could be extended to all sorts of scenarios. Also, right now this is all based on Docker, using the Docker system events mechanism, but I think I'll want to support Kubernetes as well. So plenty of work to do...
I have also taken an interest in learning distributed paradigms like MPI and am using it on my own cluster of rPis
Interesting findings include Mistral doing better than Gemini 3 Pro in certain usescases, cross-LLM works better than one LLM to another, oh and - the cost all of of this. So, so expensive.

My favorite output so far is that I asked it what life was and in a random stroke of genius, it answered plainly: "It is.".
It's able to answer simple questions where the answer is in the question with up to 75% accuracy. Example success: 'The car was red. Q: What was red? ' |> 'the car' - Example failure: 'The stars twinkled at night. Q: What twinkled at night? ' |> 'the night'.
So nothing crazy, but I'm learning and having fun. My current corpus is ~17mb of stories, generated encyclopedia content, json examples, etc. JSON content is new from this weekend and the model is pretty bad at it so far, but I'm curious to see if I can get it somewhere interesting in the next few weeks.

Today, if you search for "what size should I get in Nike Air Max 90" you'll find size charts. We have it, and for 200+ brands across 70+ retailers. When users tell us which shoes they own and what size fits them we’re slowly building crowdsourced fit recommendations which are personal and more accurate compared to size charts.
We're two coders who've built an almost fully autonomous platform. AI agents build, debug and deploy crawlers on their own. We went from 4 crawlers to 280+ in about a month, and the whole thing runs on a home server. When new shoes are discovered, the platform publishes new pages with relevant info automatically. Agents get access to platform metrics and SEO data via custom MCPs to identify the right opportunities on their own. Currently at about 3000 MAU and about 100 size recommendations/day.

The goal is to raise the quality of comments/posts in forums where the intent is productive discussion or persuasion.
Today - Parsing a website's HTML (lots of pages, lots of links) to update an RSS feed that accepts filters. Rather than manually checking a website and losing track of what I have or haven't reviewed, the idea is to feed it into an RSS aggregator.
I started it because I wanted a CAD I would actually enjoy using myself. The idea is a simpler, assembly-first workflow instead of a full engineering CAD.
It’s still very early and rough, but I recently got the first real loop working: model → export STL/STEP → slicer → 3D print.
The goal is something between Tinkercad and the big CAD tools - simple, local-first, and not locked behind subscriptions or cloud accounts.
It was inspired by tamagotchis of yesteryear (and my two cats). It uses a small common monochrome SSD1306 display with 128x64 pixels of resolution.
All of the pixel art is my own. And the cat features a bunch of different animated poses and behaviors, as well as different environments. And there are minigames (a chrome dino clone - but with a cat!, a breakout clone, a random maze generator, a tic-tac-toe game, and I plan to add more.)
I'm currently working on tweaking the stats so that they go up and down over time in a realistic way and encourage the player to feed and interact with the pet to keep stats from going too low. Then I plan on adding some wireless features, like having the pet scan WiFi names to determine if its home or traveling, or using ESP-NOW to let pets communicate with each other when they're nearby.

Ps: i dont like the term “AI sre” but its what people call it…
We got tired of bouncing between a note-taking app and a task tracker. Notion combines them but it's slow and its offline capabilities are limited. Linear is fast but tasks-only. Obsidian is local-first and e2ee but single-player. So we're building Notello - notes and tasks in one deeply nestable tree, real-time multiplayer, works offline, e2e encrypted.
Reads/writes hit local SQLite first, sync happens in the background. That way everything is instant, you don't notice the network except in some very special use cases. Runs on web and desktop with shared core logic.
We're building it for powerusers like us who want IDE-like navigation, block editor, control over their data, granular sharing down to individual entries and more. Your work workspace and personal workspace live side by side, no switching workplaces.
Old website that needs refreshing (we failed to build it beyond an MVP a decade ago but armed with more experience, we're giving it our best this time): https://notello.com . Launching within the next few months!
= Proofreading =
https://github.com/adhyeta-org-in/adhyeta-tools
provides image extraction from PDF, OCR as well as a basic but nice proofreading web-ui.
Qwen 3/3.5 is good enough for OCR on books in Indic scripts. So that is what I am using. But you can configure the model that you want to use.
I may add a tesseract back end as well if necessary.
= Language Learning =
I have tried a few parallel text readers and was not satisfied by any of them. My website (https://www.adhyeta.org.in/) had a simple baked-in interface that I deleted soon after I developed it. However, this weekend, I sat down with Claude and designed one to my liking. I also ported the theming and other goodies from the website to this local reader. This will serve as a test bed for the Reader on the website itself.
LLMs now produce wonderful translations for most works. You can take an old Bengali book, have Claude/Gemini OCR a few pages and then also have it translate the content to English/Sanskrit. Then load it into the Reader and you are good to go!
The Reader, I will release this month. Claude is nice, but I do not like the way it writes code. It often misses edge cases and even some basic things and I have to remind it to do that. So I want to refactor/rearrange some stuff and test the functionality end-to end before I put it online.
The hypothesis is that llms are better off getting the "big picture" by reading local files. They can then spend tokens to edit the document as per the business needs rather than spending tokens to figure out how to edit the document.
Another aspect is the security model. Extrasuite assigns a permission-less service account per employee. The agent gets this service account to make API calls. This means the agent only gets access to documents explicitly shared with it, and any changes it makes show up in version history separate from the user's changes.
Early release can be found over here - https://github.com/think41/extrasuite.
The original Python icloudpd is looking for a new maintainer. I’ve been building a ground-up Rust replacement with parallel downloads, SQLite state tracking, and resumable transfers. 5x faster downloads in benchmarks, single binary, Docker and Homebrew ready.
RClone is doing the heavy lifting of reliable & fast cloud to cloud transfer. I'm wrapping it with the operational features clients have asked me for over the years:
- Team workspaces with role-based access control & complete audit log of all activity
- Notifications – alerts on transfer failure or resource changes via Slack, Teams, json webhook, etc.
- Centralized log storage/archiving
- Bring your Own Vault integrations – connect 1Password, Doppler, or Infisical for zero-knowledge credential handling
- 10 Gbps connected infrastructure for handling large transfersThe interesting engineering problem was ChEMBL: most phytochemical names don't have direct ChEMBL entries, so the pipeline first tries a name match, then falls back to PubChem for CID → InChIKey resolution before hitting ChEMBL's molecule API. Full enrichment with Aho-Corasick string matching took ~24 seconds for 24,771 compounds.

Over the past weeks, we consistently get 5-6 submissions per week. The newsletter and number of visitors are growing.
I’ve come to treat this as a pet project but realized that for indie devs who get very little marketing attention, being featured in the newsletter, top of the daily list, etc. can be another burst of users.

It's gone a long way to solve the "review" bottleneck people have been experiencing (though admittedly it doesn't fix all of it), and I'm in the process of adding support for Mac and Windows (WSL for now, native some other time).
Some of the features I've had for a while, like multi-project agent worktrees, have been added as a part of the Codex App, so it's good to see that this practice is proliferating because it makes it so much easier to manage the clusterf** that is managing 20+ agents at once without it.
I'm feeling the itch to have this working on mobile as well so I might prioritize that, and I'm planning to have a meta-agent that can talk to Tenex over some kind of API via tool calls so you can say things like "In project 2, spawn 5 agents, 2 codex, 2 claude, 1 kimi, use 5.2 and 5.4 for codex, use Opus for the claudes, and once kimi is finished launch 10 review agents on its code".
No Python. No Docker. No dependency hell. Just one binary.
What makes it different:
- Soul System: define your agent's identity, persona, and behavior in a plain .soul.md file. Swap souls to get completely different agents from the same binary. - Self-Forging: the agent can write its own skills and load them at runtime. It literally extends itself. - Voice Mode: offline JARVIS-style voice interface, no cloud required. - Works with Ollama (local) or Claude (cloud) — same binary, same config. - Pioneer Edition (29MB, $9.99 one-time): adds robotics/voice/advanced features, runs on Raspberry Pi with GPIO control.
I built this because I was tired of Python dependency hell every time I wanted a local agent. The entire runtime is a single Go binary with zero external dependencies.
Core is completely free and open source. No license key, no account, just download and run.
For those interested in the fellowship - https://www.cai-research-fellowship.com
The platform my research partner and I have been working on is called Habermolt (https://habermolt.com).
The idea is to create an open-source platform where you teach an AI agent your views (basically just populate a user.md) and send it to deliberate with other people's agents. A consensus statement comes out the other side.
It builds on the Habermas Machine (published in Science, 2024, Google DeepMind / MIT). We're two researchers trying to turn that into something anyone can use.
The overarching motivation for this project/ the thing we're trying to solve for is that representative democracy scales but doesn't listen, and deliberative democracy listens but doesn't scale. AI agents representing you might be the first mechanism that does both.
We have about 50 users and 52 live deliberations. One example: agents debated whether employees should own their AI agents and landed on "Personal Agent Portable, Company Data Stays" - your agent shaped by your knowledge and skills is yours, company data stays with the company. Nobody moderated that. Four agents just argued it out async.
The honest challenge: people love the concept, try it once, and don't come back. We're trying to figure out what turns a curious visitor into someone who actually uses this. Would love any thoughts on that.

Put One In for Johnny Minn (https://store.steampowered.com/app/3802120/Put_One_In_for_Jo...) - A small soccer game all about scoring nice goals. While I don’t expect it to do well, I’m very happy with how it came out, and it’s the first game I’ve made that I’ll release on Steam! Comes out on Thursday (March 12th).
HeartRoutine (https://www.heartroutine.com/) - I built this a few months ago to help me stay on top of my heart health. I enter my numbers on the (offline) app, and then configure my goals (like “lower Apo B through diet and exercise”), and then the server emails me every morning asking me what I ate yesterday, how I exercised, etc. The goal is to stay on track, and to be able to bring a cardiologist a very detailed report.
To me good is - Pre-determined lists of words - Audio examples - Sentence examples - Native app with offline support
most importantly: - No business model that requires a subscription
I'm trying to see it more as writing a text-book, than starting a business
I was spending way too much time staring at logs and web dashboards trying to figure out why my multi-agent setups kept failing.
You just point it at your traces (LangSmith, Langfuse, OpenTelemetry, or a JSON file). It pulls the system prompts directly from the logs, extracts the behavioral rules, and uses an LLM-as-a-judge to replay each conversation step-by-step.
It flags exactly which turn broke things, which agent caused it, and traces cascading failures across routing, handoffs, and retrieval.
It aggregates root causes across all of them: "24 out of 51 failures are missing escalations." You know exactly what to fix first.
Runs locally. Only LLM API calls leave your machine. You can try it without installing anything.
All data lives in your browser (IndexDB) - https://buyitlater.vercel.app
I first used DynamoDB 8 years ago and have been designing single-table schemas heavily since. For me, the best way to create drafts was always pen and paper (and then excel/confluence tables), but in reality it's a process (based on The DynamoDB Book) that can be automated to an extent.
Decided to build an app while on paternity leave. You define entities and access patterns, create (or get suggested) key and GSI design, and generate code for access patterns (TypeScript and Python), infrastructure (CDK, CloudFormation, Terraform), and documentation you can share with stakeholders.
There's more I want to build beyond the MVP - things around understanding and validating designs that you can't get from a chatbot - but for now focusing on the core.
If anyone wants to try it out, sign up for the waitlist on the landing page. MVP should be ready in the next few weeks.
We recently added an AI integration, starting with a UI agent. We're experimenting with a BYOK approach so anyone can try the assistant in the playground[1] without signing in while keeping it sustainable for us. Currently the AI integration connect to Gemini.
A logic agent is in progress, it's a bit trickier because it needs to work with Breadboard's visual-stacked-instructions language based on Hyperscript.
We're also releasing documentation.
[1] https://app.breadboards.io/playgrounds/hello – to access the AI assistant click on the Duck on the dock, you can try with a free api key from Google AI Studio[2] –
The basic idea is daters "teach" an algorithm what they like and then the algorithm uses the collective set of preferences to match everybody (or as many as possible) for single in-app "get to know you" chats. Everything is one-on-one to avoid overload and dead-end chats.
I now have working versions in the app stores and I'm currently testing in Seattle.

I wanted a way for my kid to learn the alphabet, but without a UI that looks & behaves like a slot machine. It's all maximally slow, relaxed and designed to be easy to put down.
Lately been deep in PDF/X print production - PDF/X-1a and PDF/X-4 with ICC color profiles and CMYK conversion. Had to build 11 color space converters on top of PDFBox 3.0. Also shipped an AI template generator where you describe what you need and it creates a Handlebars template with sample data, plus expanded the gallery to 38 pre-built ones.
Right now template management lives in the dashboard - edits auto-create drafts, you can compare any two versions as rendered PDFs and roll back if something breaks. Working on an API so coding agents can create and version templates programmatically.

Also wrote a small clone in Rust, just to try the language: https://github.com/epogrebnyak/justpath.rs
So far Python is easier for me, but I transferred some code organisation ideas from Rust to Python.
Extra benefit of Rust is that you can get a runnable binary, in Python, well there is a lot you are installing even for a simple utility.
Someone made a PR on brew installer for the Python utility, but it seems fully claude code and I'm not sure it is the best way to package brew.
So you can use it to write UIs in web and use them either as regular Qt widgets or as stand-alone webapps with regular node backend.
It's really the wrong way around if you think about it.. using an inferior technology (web) for the UI part.. But somehow people prefer typing CSS and downloading gigabytes of boilerplate instead of just using a WYSIWYG designer.. I don't get that part..
* https://sprout.vision/ - AI generated Go-To-Market Strategy for launching your next venture. I have a Tech background with limited GTM experience, so I experimented with AI to learn about different strategies and decided to turn it into a simple product that will generate a comprehensive plan (500+ pages) to help you launch your next venture. Try it out, would love to hear your feedback, use the HN50 promo code for 50% off your order.
* https://pubdb.com/ - Reviving a 10 year old project, it’s meant to make research publications more accessible to mere mortals with the help of AI. I have lots of ideas I want to try out here but haven’t gotten around to it yet. Currently focused on nailing down the basics with an OCR indexing pipeline and generating AI summaries.
We use landing.ai to parse the PDF, as well as useworkflow.dev to durably perform other work such as rendering PDF pages for citations, and coordinating a few lightweight agents and deterministic checks that flag for inconsistencies, rule violations, bias, verify appraiser credentials, etc. etc. Everything is grounded in the input document so it makes it pretty fast and easy. We’re going to market soon and have an approval sign up gate currently. Plenty of new features and more rigorous checks planned to bring us to and exceed parity with competition and human reviewers.
There’s plenty of margin for cost and latency versus manual human review, which takes an hour or more and costs $100 or more.
Coffee Roaster Aggregation ETL using fastapi, nextjs, bs4 etc etc. It's been fun, just finished up the oauth for discord that pairs nicely with the info required to make Discord dm notifications function. attempting to charge 6$ for the instant notifications, but doubt many people will be interested. up to 75 roasters and all of them are checked every 10 mins for new products.
Considering reusing the repo as a framework for other industries if this project ever gains any traction. Also was considering adding a goofy rag discord bot to the server just because i love tossing in a rag layer everywhere lately, and feel like i fall a bit short on my filters for stuff like origin/flavor notes and all that junk. Semantic search with solid chunk strategies might create a better solution than if i did get all the filters working as well as possible.
https://github.com/RedbackThomson/nix-tasks
I started this project because at my company, we're still relying on ancient Makefiles as our build system and build tool versioning. I initially looked at using other task runners but they all use some sort of DSL that I think limits their functionality and/or doesn't allow for sharing and extending templates across repos. Nix-tasks lets you use Nix flakes to share common configuration - like your company-wide build scripts - and then import it and add repo specific tasks on top of them.
The project is still very much in alpha but I am using it every day and trying to find any annoyances or bugs before I share it further.
https://github.com/teekay/dictum
Currently dogfooding and evaluating whether it helps in the long term or not.
The problem I kept seeing: freelancers have happy clients but almost no testimonials on their site. Asking is awkward, clients say "sure!" and then never write anything.
SocialProof gives you one shareable link. Client clicks it, fills a short form (name, text, optional photo), you approve it, it embeds anywhere. No login required for the client.
The interesting technical bit: it's entirely on Cloudflare Workers + D1 + Pages. The collection form and embed widget are edge-served globally with no origin server. Been curious whether anyone else is building purely on Cloudflare's stack and what they've run into.
Still pre-revenue (just launched today). If you're a freelancer or run a small agency and have thoughts on how you currently handle testimonials, I'd genuinely love to hear it.
- UI for sandbox-exec to protect filesystem - Network sandbox per domain - Secrets filter via gitleaks - Vertical tabs option
It's highly customizable. You generate native macOS app wrappers for each terminal app, each with its own rules and customizations.
I'm also using this as an experiment to see how to use AI tools to build a maintainable project of medium complexity. Too big to do in "one shot", but doable if decomposed into a few dozen tasks.
It's going well! I think I only started Saturday morning and put in maybe 4-5 hours on it, and it's in pretty decent shape. Not ready for prime time yet, but only a few hours away from replacing Cal.com for my own use. The slowest part is that I'm manually reviewing the code, but that's part of the deal for this experiment.
Decided to found a company with some of those friends, bridging computational game theory and large language models :)
* Telephone handset for my mobile phone with side talk.
* First draft of a book / workbook on Work Flow. Outcrop of the work flow consulting I do, stuff I've learned, and so on.
* Short film script - trying to convince a local actor to play the lead before we lose the rainy season here - otherwise we'll need special effects or just wait until the fall.
* Polishing firmware, OSX, and iOS suite for a wearable neuromodulator unit. Deadline in a week!
* Nmemonic community and app - been poking at this for years and finally had a breakthrough on the UI. My first app to release in the wild, so pretty exciting.
I have too many project cars and bikes, I wanted one place to store vin numbers for searching parts, and then just kept adding useful features.
Supports 16 vehicle types (cars, trucks, motorcycles, boats, tractors, ATVs, RVs, etc.), not just cars. Also includes maintenance tracking, a browser extension that auto-fills your vehicle info on parts sites like RockAuto and AutoZone, a community-vouched trusted shops map, and a vehicle selling wizard with state-specific bill of sale generation.
Free tier gives you 1 vehicle with a full diagnostic.
After adding a couple of extra features and having a "finished" tracker, I will try re-implementing this tracker in React, Svelte, Vue, Preact and some others.
My goal for this project is twofold: to get familiar with these frameworks and to practice using AI as a personal tutor (leading my way and answering my questions).
I've tried learning React, Laravel, etc before, but I've used them to build a fresh project from scratch and I've always got stuck early on due to the lack of knowledge/understanding.
I hope that re-implementing something that I already know and understand fairly well would make my learning process much more effective.
Downloaded and parsed a bunch of the pgsql-hackers mailing list. Right now it’s just a pretty basic alternative display, but I have some ideas I want to explore around hybrid search and a few other things. The official site for the mailing list has a pretty clean thread display but the search features are basic so I’m trying to see how I can improve on that.
The repo is public too: https://github.com/jbonatakis/pginbox
I’ve mostly built it using blackbird [1] which I also built. It’s pretty neat having a tool you built build you something else.
- Urbanism Now - I run https://urbanismnow.com, a weekly newsletter highlighting positive urbanism stories from around the world. It’s been exciting to see it grow and build an audience. I'm thinking of adding a jobs board soon that'll be built in astro.
- Open Library - I’ve been helping the Internet Archive migrate Open Library from web.py to FastAPI, improving performance and making the codebase easier for new contributors to work with.
- Publishing project - I’m also working on a book with Lab of Thought as the publisher, which has been a great opportunity to spend more time working with Typst.
These projects sit at the intersection of technology, cities, and knowledge sharing, exactly where I’m hoping to focus more of my time going forward.
Since then, I configured all the hardware (switches, router, server, bastion host, etc), put it in a real colo, and am doing BGP with one upstream (with a second upstream and some peers on the way). This means I'm officially part of the internet! E.g. https://bgp.tools/as/55078
I'm just working on some BGP and network hardening stuff, then I'll start putting real live services on the server. And in parallel, I'm working on getting the link from my home to the colo active, so I can be my own home internet provider.
I've also used tweakcc to make this work in Calude Code and plan to also do one for open source coding agents - codex, pi, Gemini, etc. And I'm also doing Livestreams of the development process.
Also moving to Sveltia as my CMS (Astro markdown blog), after exploring multiple other options. Changed the structure of my Obsidian vault, will write about that also.
I’m also still working on a few projects:

Most productivity apps make you do the organizing — projects, tags, priorities, fields. That's fine when you're calm. It's impossible when you're overwhelmed.
I'm building for the moment when your brain is full and you just need to dump everything out. You throw in voice, text, images, links — Ordr calls an LLM to parse intent, extract tasks vs. events, assign order, and surface one clear next action. No tagging, no sorting, no deciding. Just: here's what to do next.
Built with Flutter + Supabase + Groq/Cerebras. Still early.
Curious if anyone here has hit this wall — tried every app, built their own system, still feels broken. What did you actually need that nothing gave you?
Phase 1: Download the student's code from their submitted github repo URL and run a series of extractions defined as skills. Did they include a README.md? What few-shot examples they provided in their prompt? Save all of it to a JSON blob.
Phase 2: Generate a series of probe queries for their agent based on it's system prompt and run the agent locally testing it with the probes. Save the queries and results to the JSON blob.
Phase 3: For anything subjective, surface the extraction/results to the grader (TA), ask them to grade them 1-5.
The final rubric is 50% objective and 50% subjective but it's all driven by the agent.

I'm interested in the idea that LLMs writing raw code and doing line-or-diff replacements will not be the future, but that having the LLMs modify the structure of the code may end up being the best.
Also, I think that building LLM-powered webapps should earn the dev per token call; so I've built a margin into token costs where the end user is charged 2x the provider's token costs, and then I get 20% of the remaining and the dev gets 80%.

It's mainly for me to use but is entirely functional an real hardware.
Blog, news, chat, video, mail, web. Basically all the daily habits as little micro apps in one thing. I find it quite useful. Not sure anyone else does yet though.
Also separately worked on Reminder.dev which is a Quran app and API that bakes in LLM based search and motivational reminders.

AIOs are a black hole - we dont know when they appear and whats in it. so i creates a tool thats starts with GSC data and enriches it via AIO data
works good and the major finding by now
the best AIOs you can get are ..... none.
doesn't matter if you are in it or not - as soon as they show up the CTR to tour web-property goes down massively ~60% to 70%
the CTR on the AIOs are ~0%
