My initial motivation was wanting to RDP and SSH into my home workstation from a locked-down corporate laptop when I travel. I couldn't install Tailscale on the laptop, and I didn't want to pay for a cloud VM just to do SSH port forwarding. Now I use it to tie together half a dozen machines, both locally and on Hetzner & Linode. I can SSH and RDP into remote machines, host a git repo on one machine and access it from the others, and (optionally) share files across all of them on a local mount.

You run a hub (telahubd), register machines with a lightweight agent (telad), and connect from anywhere with the client (tela). All three are single Go binaries with no external dependencies. The hub never sees your traffic. It just relays opaque WireGuard ciphertext.

All binaries run on Windows, Linux, and macOS. There is also a desktop GUI app, TelaVisor, that wraps the client and enables remote management of hubs and agents.

It's Apache 2.0-license and pre-1.0 release, but I'm polishing it for a stable 1.0 release in the next month or so.

I'm also working on an enterprise-grade management portal that works with Tela, https://awansaya.net/

It's just an mmWave sensor connected to an ESP32. But it works nicely, and I'm thinking of starting a company making them, though I'm not clear if the elderly would be ok with this minimal (no camera) intrusion.

It would just work out of the box.. the real one would have a small cell modem so it wouldn't need any networking setup, and it would act as a gateway if you have more than one in a house. There are industrial versions of this for nursing homes. This would be a bit more warm and fuzzy for home use.

I sort of got inspired to do this after seeing so many QC PR posts on HN, and finding the educational material in this space to be either too academic, too narrow in scope, or totally facile. I think given the incredible hype (and potential promise) of this industry, there should be on-ramps for technically minded people to get an understanding of what's going on. I don't think you should need to be a quantum physicist to be able to follow the field (I am only an electrical engineer).

My book tries to cover the computational theory, the actual hardware implementations, and the potential applications of quantum computers. More than that, I want to be unbiased and stray away from what I feel is misleading hype. It's been a work in progress for about 6 months now, with a lot of time spent gaining fluency in the field. But the end is in sight! :)

After winning the Playlin Player's Choice award I've noticed an uptick in players as well as some people sharing videos on YouTube which has been fun. I've got a few thousand people playing every day.

I just launched user accounts today so user's can now track their progress across devices and share their stats with each other. This ended up being a bigger chunk of work than I expected but I'm really pleased with how it turned out. (Though I launched it 15 minutes ago so I'm holding my breath for bug reports)

I'm fine-tuning my internal puzzle-building now with the goal of letting people use them to make and share their own puzzles soon!

When booking flights, I use sites like Kiwi and Skyscanner that let you do flexible searches - multiple destinations, custom connections, creative routes, etc. But rail search feels oddly constrained. All the UK train operators offer basically the same experience, and surface the exact same routes. I always suspected there were better or just different options that weren’t being shown. Where is the "Skyscanner for trains"?

After digging through the national rail data feeds, I decided to have a go at building my own route planner that runs completely offline in the browser. This gave me the freedom to implement more complex filters, search to/from multiple stations, and do it without a persistent network connection.

Now I'm finding routes that aren't offered by the standard train operators, connecting at different stations, and finding it's often easier to travel to different stations (some I'd never heard of) that get me closer and faster to where I actually want to go!

It's still a little rough and I'd like to add more features such as fares, VSTP data, and direct-links to book tickets, but wanted to share early and get some initial feedback before investing more time into it. So, thanks in advance - let me know what you think.

I love cooking but the daily "what do you want" grind was killing me. Rushing to the store after work hoping for inspiration but leaving with the same five fallback meals. Recipes using half a box of something so you eat the same thing twice or watch leftovers die in the fridge.

The final straw was our newborn's milk protein allergy, turns out milk is in everything. Recipe sites are hostile. Ads reload and jump the page mid-sentence, 20 versions of every dish, comparing the 4.7 star rating version with the 4.8 star one. So you go by thumbnail. Visual clutter everywhere.

I tried the apps. One does swiping, one does shopping lists, one does Sunday budget planning, one has "what's in my fridge" mode. Pick your half-solution.

So I built what I wanted: swipe mode that makes picking dinner fun again, or instant 3 quality suggestions for when I am in the store. Aisle oriented shopping list, budget, personal taste, fridge inventory in one place. UI looks like a restaurant menu — off-white, black text, no glossy photos. I'm working on AI mode now. Not for recipe generation, which are mostly garbage, but for search and substitution.

I'm still obsessed with making my game, which you can try it at the link above (it is desktop only). This is my first "real" game, and it has been incredibly fun and rewarding. I've been working on it in the evenings for about 4 or 5 months.

It is a very ambitious mix of genres - shoot-em-up and deck-building. A lot of people said that those are genres that shouldn't be combined, but I think it turned out to be a fun little game. Folks who are not fans of one (or either) of the genres are actually playing it. I built a global high-score leaderboard, and there are people (including a few of my friends) competing on it. Whoever knocks my friend "BER" from first place will earn a beer from me.

This is purely a fun project, although I'm now seriously considering releasing it on steam when I finish everything I planned for it. It is made in Kaplay, a small JavaScript gamedev library, which is a big part of what makes it fun. If you try it out, please leave a comment, I would love more feedback!

I live in Lisbon and I've been learning Portuguese with a tutor since 2022. After every lesson I'd sit down and make flashcards from my notes and screenshots. Spaced repetition works, but making the cards took manual effort each time. Most days I just didn't do it. So I have automated that process.

The flow: you invite the Kardo bot to your call, it records and transcribes (Recall.ai + Deepgram Nova 3), then GPT-4o extracts vocabulary from the transcript and generates cards. You review them with spaced repetition — we use FSRS, which is the best open algorithm I could find. If you already use Anki or Mochi Cards, there's export.

You can also throw in YouTube videos, podcasts, articles, PDFs — not just live lessons.

Tech: built entirely with Claude Code. React + Vite frontend, Bun + Elysia backend, Convex for the database, Railway for hosting.

We got 50 beta users through Telegram, and just landed our first paying customer. Now we're trying to figure out distribution — tutors seem like the obvious channel because one tutor recommends you to all their students, but reaching them with zero marketing budget is the hard part.

Curious if anyone here learns a language with a tutor and what your review workflow looks like.

Looks like it is a crowded area now - my angle is to start with theory of what is important in a system like that, from first principles (like agent limited context, statelessness, use goals etc). Currently I use it to develop that theory - and you can read it at: https://zby.github.io/commonplace/. I also use it to keep an index of similar systems (that is systems with agent operated memory): https://zby.github.io/commonplace/agent-memory-systems/

The github repo is at: https://github.com/zby/commonplace . Work in progress.

I want to show how I liberate poorly aligned, pixelated PDF image scans of century-old Latin textbooks from the Internet Archive and transform them into glorious Org mode documents while preserving important typographic details, nicely formatted tables, and some semantic document metadata. I also want to demonstrate how I use a high-performance XML database engine to quickly perform Latin-to-English lookups against an XML-TEI formatted edition of the 19th century Lewis & Short dictionary, and using a RESTXQ endpoint and some XQuery code to dynamically reformat the entries into Org-mode for display in a pop-up buffer.

I intend demonstrate how I built a transcription pipeline in Emacs Lisp using tools such as yt-dlp and patreon-dl to grab Latin-language audio content from the Internet, transcode the audio with ffmpeg, do Voice Activity Detection and chunking in Python with Silero, load the chunks into Gemini's context window, and send it off for transcription and macronization, gather forced-alignment data using local a local wav2vec2-latin model, and finally add word-level linguistic analysis (POS, morphology, lemmas) using a local Stanza model trained on the Classical corpus.

This all gets saved to an an XML file which is loaded into BaseX along with some metadata. I'll then demonstrate some Emacs Lisp code which pulls it into an Org-mode based transcription buffer and minor-mode for reading and study, where I can play audio of any given Latin word, sentence, or paragraph, thanks to the forced-alignment and linguistic analysis data being stored in hidden text properties when the data was fetched from the database.

Lastly, I'd like to explore how to leverage these tools to automatically create flash cards with audio cues in Org mode using the anki-editor Emacs minor mode for sentence mining.

It's a top down ARPG called Mechstain where the player creates and pilots voxel based mechs

Instead of traditional gear, your mech has a physical voxel footprint that you the player have to fit weapons and components inside

Your job is to manage space, power and mass, what you can fit and power directly becomes your stats and abilities, essentially a bin packing problem

Basically take Diablo 2 and remix it with Kerbal Space Program, still fleshing out the various systems, but I'm really enjoying the process of slowly designing systems, iterating on it and fleshing it out

It's quite fun taking thoughts I've been noodling on for years and trying to figure out if they synergise with what I'm looking at and do they provide interesting player decisions

Recently onboarded a 3d artist and it's really making things look a lot better

This is my first Minecraft Mod and the first project i made that interacts with the network, has logins/accounts and does APIs.

I am really not good and thus the UI (far worse on mobile) and especially the Code is bad, but i would have never expected to get it working at all, much less this functional. But i am still far from done, i still want to improve the overall code quality, add the inventory and ender chest, achievements (maybe even custom ones so vanilla clients can earn and view them without having to change anything locally. IDK yet) and more.

If someone wants a small demo, i have it running on my server to test while I am developing at: https://grisu-ftp.de (If you find any issues lmk :)

While this is by far not as cool as the other stuff on here i still would like to show it off and gather some first feedback. This is my first Java project that goes above the Standard stuff in school like scanners/calculators and so I have probably done obvious beginner mistakes.

To resolve this, I am currently fleshing out the idea for a "shared hosting" for vibe coded programs - something like a cross between an old school LAMP stack shared host and a parse like library for capabilities like push notifications.

It's all very half baked in my head at the moment - with the biggest problem being a safe way to deploy remote code without pawning the server, but this is a problem shared hosts have dealt with and I am sure I will eventually figure out a way.

The end goal is to be able to have people tell their AI agent of choice to "make their app deployable" on our platform - and the agent will adapt it to our library methods and deploy automatically. Once done folks will be able to access their programs from any internet connected device.

Air quality data is now very widely available, but managing access to multiple networks is a massive task (lots of shonky APIs out there - the EEA has a csv endpoint that actually returns a .zip with mimetype "text/html", just to give you a flavour). Integrating new APIs could be a full-time job, but it's something AI can do very well given a pattern.

This is really for me as I build out my company working on turning air quality data into actionable information, but it's open source and freely available.

The use case is kind of neat. RAID is great and can mostly solve these problems, but people don't have SATA hardware that can handle the workload well, plus they aren't ready to manage an array like that, and they don't like having to use specific sized drives, etc. Another major issue with those setups is you need to be careful because an IO error that you don't recover from will be very difficult or impossible to recover from because of the layers of LUKS combined with LVM.

With MergerFS you just use regular file systems that are separate, but they get combined into a single mount point. That means each disk can just be a different LUKS encrypted drive and if you need to recover data it's isolated to that one disk and much more manageable. You can also take any disk and plug it into another machine as needed and grow or shrink the storage pool as needed.

MergerFS has options and settings to help you determine how files are spread across the drives, such as least space used or which disk has the most of that directory path already.

My app (Chimera) automates the unlocking of the disks, mounting and some data migration if you want to remove a disk from the pool. I plan to add some rclone features to help provide easier backup options to places like Backblaze, AWS, or a remote server in general.

So far so good and I was surprised at how well Opus had been handling Gtk and pkexec.

Let me know if you guys are interested I am close to pushing some RPMs and DEBs, in addition to the standard Python stuff.

So I built an on-device OCR engine (PaddleOCR) that reads screen text locally and feeds it into an AI sentiment analysis pipeline. No screenshots leave the machine. We now get alerts if there's detection of concerning interactions. The client is written in Rust, with DNS filtering, game detection (Steam/Wine/Proton), and screen time enforcement built in.

It started as a home project that worked really well. My wife suggested other families wouldbenefit, so I've been building it out as a product. The client shipped on Linux first, we're a Linux gaming family, with Windows coming soon.

I've been running models on my homelab for a bit now, but none of the available options out there was what I wanted. I wanted something that I could command from the CLI, API, or Web, so have an agent go in and do work remotely via SSH or myself via a web interface.

I wanted the ability to know if models have been updated, and if backends (llama.cpp, ik_llama.cpp) have been updated, see what those updates are and choose to update. Also wanted the ability to switch betwen versions of those, so if I felt like there was a regression, or performance issue, I could roll back.

I've also published plugins for OpenCode and Pi so that model discovery is automatic too.

I'm building this mostly for me, as usual.

Model output volumes mean that code review only as a final check before merge is way too late, and far too burdensome. Using AI to review AI-generated code is a band-aid, but not a cure.

That's why I built Caliper (http://getcaliper.dev). It's a system that institutes multiple layers of code quality checks throughout the dev cycle. The lightest-weight checks get executed after every agent turn, and then increasingly more complex checks get run pre-commit and pre-merge.

Early users love it, and the data demonstrates the need - 40% of agent turns produce code that violates a project's own conventions (as defined in CLAUDE.md). Caliper catches those violations immediately and gets the model to make corrections before small issues become costly to unwind.

Still very early, and all feedback is welcome! http://getcaliper.dev

You can read more about it over at the site, but it allows you to construct and validate arguments in a graphical form, and it has truth/proof propagation so you can see whether a conclusion is currently considered valid or contested. You can create counterpoints where you think the argument breaks down, and strengthen arguments from there. Some upcoming plans are to allow users to validate arguments for themselves, like mark which parts they understand and agree with so they can collapse that part of the graph, and to add more mcp capability so that LLM can help you construct and validate new arguments.

After 4 years of maintaining an Open Source Design System, I needed a better way for theming than Sass and PostCSS. I needed the power of a full-featured programming language. That's how the first version of Styleframe was born.

My vision is for Design Systems to be endlessly configurable and composable, like you would configure any library, with or without AI. Want to change your entire website to look like Linear? Simply install and use the Linear Design System configuration. Want only your buttons and cards to look like Linear, and the rest be the default theme? Use the button and card composable functions from that package.

Styleframe is built as a transpiler-first system. You write your design tokens, selectors, utilities, and recipes in TypeScript, and Styleframe tokenizes everything into an internal representation. From there, the transpiler generates dual outputs:

- CSS output: variables, selectors, utilities, themes, keyframes

- TypeScript output: typed recipe functions with full IDE autocomplete (with an optional Runtime)

This architecture means you can have complete control over customizing how your system is output. You could even use the generated tokens to render documentation for your design system components. The output code can be integrated with any headless UI Components Library, or with your own custom components.

Fun fact: I've reimplemented the entirety of TailwindCSS using Styleframe's utility and modifier tokens. Not only that, but I've also built a scanner which picks up your CSS Classes from your markup. It's basically Tailwind, but 100% configurable (even utility class format can be changed), and is always based on your design tokens.

At a first glance it's a mobile proxy service, but the entire backend of it allows anyone to create their own mobile proxy and be able to access it anywhere through the internet, seamlessly. That's the 2nd phase of the website which is still long ways to go, but very happy with how stable the platform is and how fully it's automated.

Tech stack is a bit unconventional for a public facing website, as it's Blazor Server. As a C# dev in my day job, I've found Blazor to be quite capable and stable to quickly iterate through my ideas. And was pleasantly surprised to see how easily I can deploy the app into a Linux VPS through docker, which I didn't think was possible a few years ago.

It's a free USCIS form-filling web-app(no Adobe required). USCIS forms still use XFA PDFs, which don’t let you edit in most browsers. Even with Adobe, fields break, and getting the signature is hard.

So I converted the PDF form into modern, browser-friendly web forms - and kept every field 1:1 with the original. You fill the form, submit it, and get the official USCIS PDF filled.

I found out SimpleCitizen(YC S16) offers a DIY plan for $529 [2]

Petrify is a machine learning model compiler for the the JVM. It reads your model from an ONNX or other model format, walks the Trees or Linear models, and encodes the model in equivalent JVM bytecode as a stateless class you can invoke.

This differs from every other ONNX Runtime that I know of, which are essentially interpreters. The ONNX Runtimes are also huge (90+mb!?!), JNI, and drag gargantuan dependencies!

This just compiles your models to native bytecode. Much simpler and you end up with 0 dependencies! (you need one interface technically, but I digress).

I had an insight the other day, that as I fix the n least (and most, it's a palindrome!) significant decimal digits, I also fix the remainder from division in 5^n. Let's call it R. Since I also fix by that point a bunch of least (and most) significant bits, I can subtract how much they contribute mod 5^n from R, to get the remainder from division in 5^n of the still unknown bit. The thing is, maybe it's not possible to get this specific remainder with the unknown bits, because they're too few.

So, I can prepare in advance a table of size 5^n (for one or more ns) which tells me how many bits from the middle of the palindrome I need, to get a remainder of <index mod 5^n>.

Then when I get to the aforementioned situation, all I need to do is to compare the number in the table to number of unknown bits. If the number in the table is bigger, I can prune the entire subtree.

From a little bit of testing, this seems to work, and it seems to complement my current lookup tables and not prune the same branches. It won't make a huge difference, but every little bit helps.

The important thing, though, is that I'm just happy there are still algorithmic improvements! For a long while I've been only doing engineering improvements such as more efficient tables and porting to CUDA, but since the problem is exponential, real breakthroughs have to come from a better algorithm, and I almost gave up on finding one.

I have a recursive ascent code generator with a bunch of optimisations that I wrote about [1,2]; it's a linear-time parser for LR(1) with reduced overhead. I have an RNGLR implementation (a polynomial-time parser for any context-free grammar), that's still a table-based interpreter like more LR-based parsers out there. I've extended that implementation with special code to handle cycles more efficiently. Some day, I'll take some time to write a paper on that and publish it. Currently, I'm trying to combine the two ideas and create a generalised recursive ascent code generator. If I succeed I'll write another blog post again, it's been a year since the last one...

Subscriber:-> entity who orders/shops

Market: -> the agents that work with the farmers or markets

The opposite of the favorite questions: Why did that company I worked for fail? Why did Rome collapse? Why do people get old and die?

Combining information theory with thermodynamics and control theory you get: 1) A set of six pillars that all systems that persist must have. 2) A fundamental 'Action' that all of these systems take. 3) A set of three rules for how system that persists must subdivide

This lets you do things like look at something that is failing and know that there are the 6 pillars and you can then identify them to determine what is failing. (For example there is a system that clears that brain of amyloid plaque and it can fail).

I have applied this to countless systems including Religion, Language, AI Models, Business, the cell, quantum physics, number theory and much more. It is a Rosetta Stone for persistent systems. When there is an unsolved problem in one domain I can map it through this to any other domain that has already solved it.

Note that this doesn't apply to all complex systems, only those that persist.

And to keep this HackerNews related, been applying it to LLM's as they are just a stream of tokens that try to persist to incredible success I might add. Being able to pull from any domain do this brand new field is a giant cheat code.

Written in C++ and Slint, it was also a testbed of slint as an UI framework. Having used wxWidgets in the past, and Qt recently, it is certainly a different thing. I just wish there was a native C++ alternative to slint.

I need to integrate the CI to produce binaries, but you can compile it yourself for now.

It's an iOS app that applies various generative art effects to your photos, letting you turn your photos into creative animated works of art. It's fully offline, no AI, no subscriptions, no ads, etc.

I'm really proud of it and if you've been in the generative art space for a while you'll instantly recognise many of the techniques I use (circle packing, line walkers, mosaic grid patterns, marching squares, voronoi tessellation, glitch art, string art, perlin flow fields, etc.) pretty much directly inspired by various Coding Train videos.

Direct download link on the App Store is https://apps.apple.com/us/app/photogenesis-photo-art/id67597... if you want to try it out.

I got frustrated with Claude Code and Cursor producing plausible-but-wrong changes with no easy way to annotate and push back, without making a full PR. crit makes the review stage fun again!

Works on both plans as well as code itself. It’s been very rewarding hearing from folks who use it, everyone has been very kind! My most successful side project already :)

What I've noticed personally and with founders I talked to is that communication and email triage takes a large amount of time each day, but mostly only needs a quick decision or rerouting the right kind of information. But all this mental overhead takes away time from the really important strategic tasks that you should be working on as a founder.

That's where Chief of Staff comes in. Like a real chief of staff, it gives you a head start into the day: checks your calendar, your incoming emails and messages, prepares meeting briefs and drafts responses.

But it goes further than your typical smart inbox: by sharing your strategic goals it prioritizes and makes sure you are working on the highest leverage items. It also helps you manage relationships by tracking communication frequency and sentiment, so you don't miss when a key customer goes cold.

Both Superhuman and Lindy fell short in key areas of the UX for me: Superhuman makes email triaging faster, but you're still the one doing most of the work. Lindy is highly customizable, but you'll spend a ton of time building and tweaking workflows. I wanted a batteries-included approach to get started right away by just connecting Gmail, Slack, and Calendar without any additional configuration.

A key UX decision for me was also that I stay fully in control. Chief of Staff reviews, analyzes and prepares, but I am the one hitting send.

I'm testing it with a very small crowd right now, but want to open it up soon. If you feel that this is an issue you want solved for yourself as well, feel free to reach out to me and I'll get you on the list for the private beta.

If you have strong opinions for or against this approach, I wouldn't mind hearing this either :-)

You can use the agent from any client (web, Slack, Teams but also other harnesses).

We think most of data analytics work will be transformed (and is already being transformed) from SQL monkeys to chat to analyses, but all the UI/UX are not designed for this and this is what nao is, being open-source because knowing how the context is managed is key.

With nao you can have a conversation and then shared the output on the form of a story, that can be either static or live replacing what old dashboards were.

It is:

- open source

- accountless(keys are identity)

- using a public git backend making it easily auditable

- easy to self host, meaning you can easily deploy it internally

- multisig, meaning event if GitHub account is breached, malevolent artifacts can be detected

- validating a download transparantly to the user, which only requires the download url, contrary to sigstore

Nearing Alpha release stage.

The idea came after I finished a permanent piece for a museum using MaxMsp and python. I always had this thought in the back of my mind that "I could express this so much easier in a few lines of code.."

Check the docs folder for the full language spec.

I really liked how objects came out, I don't think it needs any more since I can do object composition.

There are some nice functions to generate rhythms and melodies with combinatorics, see src/sequences.rs and melodies.rs

I'm not sure if I'll every productize it in any way, but I could see a world where it's used by people prepping for the bar, med boards, various continuing education stuff. Right now it's just a fun platform to build on as I explore the current wave of technologies. Building a framework for evaluating different LLMs for best price/accuracy. Adding a RAG pipeline so wrong answers can point back to source material for further review, etc.

I'm looking at moving from backend engineering to a more MLE or agent pipeline role, so this is giving me something more than school projects to build on. While also helping me do better at school.

8/15 on SWE-bench Verified vs Claude Code's 5/15, ~$0.06/instance vs ~$0.12. Small sample, single repo, lots of caveats. But the direction feels right. Event-sourced reducer, no framework deps beyond the Anthropic SDK.

Each cat mirrors the agent's state, such as sleeping when idle, walking when working, sitting when waiting for input, running toward your cursor when it needs permission.

Fully native Swift, no Electron, under 5 MB, zero network requests, all session data stays local as plain JSON.

I published it source-available with an honor-system license, but this week I’m going to fully open source it and remove the licence. The payment/nag system was an interesting experiment but the project is more useful to me as a proper OSS tool at this point.

The main thing I'm currently working on is a platform for organizing and discovering in-person events. Still not certain about the boundaries for "Phase 1", but I have a bunch of ideas in that space that I've been incubating for a while. One subset of features will be roughly similar to that app you've probably heard of that starts with 'M' and ends with 'p', but hopefully an improvement, at least for the right audience. But wait, there's more. :)

Currently building it; it's not public yet, so no link. Next month. I also have an external deadline around that time.

Thinking about how to grow the userbase is intimidating, but I think it might end up being fun.

by Cyphase

Well, this is the app that answers that. Everything is seamless, you don't configure anything. You simply start the app on the Mac Mini, import the photo folder, and let it run in the background. In the kitchen, you simply take your iPhone or iPad, open the app and voila, all photos from all libraries show up, organized by date, place, album, people, event. You want to see photos from Prague? You simply check Prague from the filter sidebar. You want those from 2008? You check 2008. Done.

This is not an AI search-based photo library. You cannot even search. Everything you can search for is laid out in the sidebar. You don't need to remember where you have been in 2008. You check 2008 - you see all locations, all albums, everything from that year. You want to see how many trips you had to Vienna? You check Vienna. It's kind of old school this way, but I find it much mentally sane to see a list of filters with things you have done and places you have been and dates you took photos in, rather than an empty search input open to guesses and missed attempts.

This is also not a replacement for your Apple Photos app, or a photo editor app. This is not a photo editor. It's simply a better way to browse historical photos, in a home network, without thinking about it.

I've worked with data my entire career. We need to alt tab so much. What if we put it all on a canvas? Thats what I'm building with Kavla!

Right now working on a CLI that connects a user's local machine to a canvas via websockets. It's open source here: https://github.com/aleda145/kavla-cli

Next steps I want to do more stuff with agents. I have a feeling that the canvas is an awesome interace to see agents working.

My problem: my super-long, months-old ChatGPT threads were breaking down. Even typing got slow, and the longer the threads got, the more they hallucinated. I loved Google AI Studio and paid for it, but I was constantly deleting and re-editing the same thread just to try a different angle. And I couldn't run multiple frontier models against the same context or files without copy & paste and tab switching.

I do 99% of my AI work now in Alyph. One board instead of a dozen tabs, branch anywhere, hot-swap models on the same context. Best guess: I'm 3x faster building things. The honest 1% failure case: it's too slow to load for a quick throwaway question.

Hardest technical problem so far: layout algorithms for an infinite canvas.

Beyond standard features (retries, caching, timeouts - enabled with attributes on the decorator), Coflux supports more novel features - like suspense (where a task can choose to go to sleep and get restarted when a result it depends on becomes available), memoisation (where steps within a run are aggressively cached so that you can re-run steps in a workflow without re-running upstream steps), and the ability to re-run a step in a different workspaces (with updated code, or in a different environment).

It turns out this works great for implementing agentic systems - you can provide references to tasks as tools to an LLM call and have the AI drive - tasks can be easily sandboxed. And Claude is very capable of using the CLI to interact with the orchestration server to submit workflows, investigate failed runs, make updates to workflows and re-run steps.

I'm trying to make sure it's easy to try out - there's a self-contained CLI that can be used to start the server (a single Docker container), run worker processes, and then interact with the server. The dev mode automatically restarts the workers as you make local changes. There's also a hosted UI for observing runs in real-time, where you can see the execution graph, access logs/metrics/assets/etc - it works without creating an account - the browser interacts with your orchestration server directly.

Platform deterministically generates tasks, creates environments for them, observes AI agents and then scores them (not LLM as a judge).

We just ran a worldwide hackathon (800 engineers across 80 cities). Ended up creating more than 1 million runtimes (each task runs in its own environment) and crashing the platform halfway.

Also this week launching https://dirtforever.net/ which is an open alternative to RaceNet Clubs for Dirt Rally 2, since EA is shutting that down.

I'm also expanding the SDK and plugin space for https://fastcomments.com and am planning on adding AI agents because everyone expects that now :) a big challenge is building it in a way that doesn't make half the users mad. So I'm planning on marking any comments left by AI mods with a "bot" tag, and having the system email users on why it made certain decisions, with an option to contest that loops in a real person. I'm hoping this provides value to site owners while not angering real people. The agents could also just do non-invasive things like notify certain moderators when comments violate community standards in some way, or give out awards. I'm also hoping at some point I can run my own hardware for the LLMs so I don't have to share people's data with third parties.

You get to choose the genres you're interested in, and it creates playlists from the music in your library. They get updated every day - think a better, curated by you version of the Daily Mixes. You can add some advanced filters as well, if you really want to customise what music you'll get.

It works best if you follow a good amount of artists. Optionally you can get recommendations from artists that belong to playlists you follow or you've created. If you don't follow much or any artists, then you should enable that in order for the service to be useful, as right now that's the only pools of artists the recommendations are based on.

Data support tool for pharmacists to identify savings and best value opportunities for their local health system (NHS/UK)

Been a hobby coder for about a decade now, but this is my first attempt at a full stack application (airflow, db, backend, frontend).

Command replaces that with a platform that maps to their real sites, real assets, and real operational constraints, so they can actually run the program, not just document it.

The core frustration: Apple Watch collects HRV, sleep stages, respiratory rate, blood oxygen, resting HR. Apple does basically nothing useful with any of it. You get ring animations and step counts.

Atlas pulls all of that together and turns it into two scores: recovery and training readiness. The point is to actually use the signal your sensors are already collecting and ensure when you train, it matters. It’s like Whoop, but actually works.

For those DMs that use tools like these, my app sits between Shieldmaiden and Improved Initiative in terms of features/complexity. I tried to offer as many features as possible but "hide" them in a way that makes it easy to understand the most important information like initiative order, health and conditions, stat-blocks. But then I added many buttons with keyboard shortcuts and a quick-access command-palette (think MacOS Spotlight or Alfred on Linux) that lets you access even more commands and features just by typing.

- Weirdly, the kitchen sink is almost exactly the geometric center of the house; hence, equal probability for odors to travel.

- And that reminds me: Need to download PDF for dishwasher operation.

- Day 2 (Friday) of my wonderful better half's travels, I started laundry. I remembered less then 2 days later that I need to transfer the clean (??) clothes from the bottom device (water/soap) to the upper "dryer" -- this device produces some serious heat. Kills odor causing bacteria, and stuff. Will call that a success.

- I find my clothes are scattered on the floor randomly. Seriously high entropy -- reminds me of CloudFlare's lava lamp application: https://en.wikipedia.org/wiki/Lavarand

Native cross platform app coded in rust + tauri.

I prefer using it to the other agentic code apps I have used. It has multi tab worktree isolated agents, sandboxed tools, git integration, built in code editor (with inline generation), searchable document support (i.e. upload your docs, datasheet and you or the agent can use them) and even built in local image generation (using stable diffusion and flux schnell) and asset handling for game developers. Oh it also has a remote feature so you can share the gui or deploy it on a server and access it on the go.

It’s a command-line tool for decoding certificates and CSRs into structured JSON rather than OpenSSL-style text output.

It decodes the underlying ASN.1/DER structure so fields and extensions are fully expanded, making the output easier to work with programmatically.

I’m planning to expand it to support more PKI artefacts (e.g. CRLs, Keys) over time.

I’m also planning to handle less well-formed inputs (e.g. missing PEM headers/footers, whitespace, or extra surrounding text), which tends to come up in real-world data.

It’s free to download — would be great to get feedback if anyone tries it.

Here are the areas of analysis:

    - accessibility
      -- check for images with missing alt text
      -- check for various form controls missing labels
      -- headings not following (h1->h2->h3...)
      -- missing lang attribute on <html>
    - content
      -- check for forbidden words and phrases
      -- check for required words and phrases
    - performance
      -- evaluate time to load page
      -- check for excessive inline JS
      -- check for inline styles
    - security
      -- check for SSL certificate expiring soon
      -- check for security HTTP headers
      -- check whether Server HTTP header is too revealing
    - seo
      -- check for missing title in head section
      -- check for missing meta description
      -- check for multiple H1 headings
    - site integrity
      -- check for broken links
      -- check for use of deprecated tags
      -- check for insecure http link
    - spell check
      -- check for possibly misspelled words

You can provide the DM a premise (or pick one from the library) and it'll flesh out a full campaign story arc. Either way it's a fresh story arc reacting to your actual decisions, every time.

I noticed every competitor in this space was a chatbot with only the last ~10-15 messages stuffed into context. They forgot things, made up dice rolls and rules, and was generally not what I was looking for. So far TableForge has been working well for my friend groups and some random folks from Reddit/organic search. Solo TTRPGers seem to like it too.

It's still in early stages but fully playable. I don't feel comfortable charging anything for yet until I know people enjoy it. If you like it enough to hit the free tier limit, send me some feedback in the webapp and I'll gladly extend your free trial. If you hate it, please also let me know!

It is scientifically proven[1] that sitting is detrimental to our health, with increased mortality rates. The primary way to reduce the negative effects of sedentary work is to move.

This means doing sessions of resistance training (gym), running, biking, but also taking micro-breaks during work sessions and performing light exercises and stretches.

Research has shown[2] that taking short breaks during work reduces fatigue, and in some cases actually boosts performance.

There are plenty of running and gym apps out there, so Limberly focuses on the last part - helping you take micro-breaks, reminding you to change your posture between sitting and standing, changing which hand holds the mouse (if you're into that) etc.

It is still in early development, so if you'd like to help test and shape the app as we go, please sign up for the waitlist and I'll add you to the testers group. Feel free to also DM me here with any questions or feedback.

I wanted to make it easier to quickly see/study trending articles on Wikipedia because they tend to make good topics to know before going to trivia night.

I've had the domain for awhile, but just made the app today on a whim.

I use Wikimedia's api to get the trending articles, curate them a bit, add some annotations to provide some context, then push to deploy the static site.

I couldn't find any crate that would be ergonomic enough to use and provide features I deem essential, i.e. retryability, scheduling, poison job detection, barriers, backoff strategies etc.

it's an area I'm familiar with so after spending 2 days trying to integrate external libs I decided to roll my own and I'm quite happy how it turned out in 2 days of development.

I plan to open-source it in the near future but right now using it in my another project and it's running quite well.

It's web service that allows you to channel your google docs through a more human-friendly name. So, you link

opendocs.to/your-name/resume (an example link)

to your public resume at docs.google.com/dlkjbalksdfd

It's a simple redirect service, but it just looks nicer, and I think the opendocs.to sounds natural. Got to learn a lot with this one, using Vite/React, Node, Postgres all in Docker, with a local profile that builds nginx inside with the containers, or a prod profile on the server where nginx proxies into the containers.

Anyways, check it out!

Right now, only free tier available as I some last tweaking and checking.

Both peers mount a virtual FUSE folder. Files shared by one side appear in the other's folder in real time. You can open, copy, and browse your peer's files as if they were local. Files go directly between devices over encrypted gRPC. (by default it tries over LAN, then direct IPV6, then uses a data relay).

The hardest part has been making git repos work through the FUSE mount between peers.

Got fed up with web tech, it's so slow and clunky, so made my own version in python and qt. I changed the design to be based on a doclayout llm, so you can skip or include things like tables and references easily.

It now works so beautifully fast, it's code is readable and simple, no apis or multiple services. Just a qt app, some local llms that can run on a decent cpu and word-leven highlighting and playback selection.

I’ve been building a phone app + website (https://MyBulkCards.com) to scan cards and organize where everything is. It’s pretty basic right now, but I can store cards in boxes like “Box 1 AAA, Box 1 BBB, …” and find cards easy peasy. There’s also a friends feature so I can see what others have locally. We borrow cards from each other quite a bit.

It’s been a fun project to build. I trained one model to find a card in the camera frame and another to identify it. Still iterating a lot. One epoch on my Mac M4 takes about 2 hours, and I’m still seeing improvements past epoch 10. Even now, it can find and identify a card more often than not, even without the OCR bits. Both models are under 20MB, run directly in the camera frame, and are fast enough to identify a card as I slide it into view.

I started with Android since that’s what I have, and I’ve shared the app store testing link with my local group for testing. The app is built in React Native, and I’m hoping to get an iPhone version out soon since there are a bunch of iPhone peeps. A couple of the players also got me into MTG, so now I’ve got a pile of Turtles cards too. I’ll be training an MTG model next. I don’t think it’ll be too bad since I can reuse most of the same approach.

The Registry in turn has two interfaces: one REST, and one A2A itself. If you hit /.well-known/agent-card.json on the Registry server, you get the AgentListerAgent, which supports searching for Agents by various criteria. Or you can search using the REST interface. In either case, you get an AgentCard that points to the correct APISIX endpoint to talk to the desired Agent.

Besides adding K8S support, other plans include adding support for other proxy providers (including Istio for the K8S case), supporting Agents that are not based on A2A and, allowing Agents to register themselves using the Registry API, and... uh, well, that's the main stuff I have in mind right now. Aaah, wait, I might do something along the lines of integrating an MCP Registry as well, not sure yet. Heck maybe I'll get bored and make it an all-out API registry for all sorts of endpoints... could integrate a UDDI server and bake in WSDL support for good measure! (Don't count on that last bit happening anytime soon).

Anyway, no repo to share right this second, but I do intend to make it open source. I'm just committing the cardinal sin right now of wanting to "make it presentable before releasing the code".

by mindcrime

Like PocketBase, it's made in Go, has an admin panel, and compiles down to one executable. Here, you write your endpoints as Lua scripts with a simple API for interfacing with requests and the built-in SQLite database. It's minimal and sticks close to being a bare wrapper around the underlying tech (HTTP, SQL, simple file routing), but comes with some niceties too, like automatic backups, a staging server, and a code editor inside the admin panel for quick changes.

It comes from wanting a server that pairs well with htmx (and the backend-first approach in general) that's comfy to use like a CMS. It's not exactly a groundbreaking project, and it still has a ways to go, but I think it's shaping up pretty nicely :)

I’m trying to solve this by building high-quality, lightweight landing pages at the most affordable rate possible. Right now, I’m running a promotion: we’ll build your landing page (up to 2 pages) for free if we handle your domain hosting.

I craft each site individually to ensure they meet modern web and cyber standards—no copy-paste layouts. I’d love to hear your thoughts on the model or any feedback on the tech stack.

It lets you create TV channels from digital media such as YouTube, The Internet Archive, TikTok, Twitch, and Dailymotion. It does that by letting you schedule videos against a custom calendar system.

Since filling out even a month of content can be a lot of work, I built some things to make the process easier.

* Advanced scheduler to know when and how long content can be played at any given datetime

* Real time team collaboration

* Channel libraries to organize media

* "Blocks" - Create a dynamic schedule which generate hours of content that mimics real television scheduling. It even carries over your playback history between generations so that playlists continue from where they left off.

* A catalog to find media from official sources on YouTube

* Embeddable as an OBS browser source to restream your owned content

* Repeat content infinitely or temporarily to create 24/7 channels.

If all goes well I am hoping to re-release sometime this month.

Unlike those apps it has full support for design tokens and (so far) flexbox layouts. It can also export directly to HTML, rather than a fake preview mode. I’m also working on full code-backed components, so you can go between code and design very easily.

As a designer, I’ve been frustrated for years by the gap between design and code, and despite all the new AI features, Figma still hasn’t got any further in years - design tokens need a 3rd party plugin and responsive designs are a pain in the bum. So I decided to build something that has the ease of Figma while being much closer to live code.

I’ve got to the point where I’m designing the app in itself, tokens are working, html export is working and nearly ready for first betas.

No traffic ever leaves your local network and since it uses rsync under the hood the devices being sync'd to don't need to run anything other than SSH.

It's a single file shell script that has no dependencies except rsync. It's literally 1,000+ lines of defensive checks and validations to make sure you're not shooting yourself in the foot with rsync, and at the end the last line of code directly calls rsync. It doesn't try to reinvent the wheel by replacing rsync (it's an amazing tool).

Random observations from my first one: - presenting my idea visually helped crystallize my thinking in a way that writing doesn’t. And writing was already very good at crystallizing my thinking. - even making a bad video was a lot of work - making a video presentable is a deep subject. Subtle changes were throwing off my setup. Now I understand why so many influencers are fitness and lifestyle; the demand side is obvious, but when you’re already camera-ready you have a huge advantage on the supply side - described something I built felt natural. I do that for a living. The intro was like 45 seconds and took me like 45 minutes to film because it was acting and I don’t know how to do that - learning about video editing features had an immediate payoff because video is so long

Resuming work. I used to `j <reponame>` then `gco <branchname>`. Now if I do that I get an error about the branch being checked out already in another worktree. I realized the branch names are pretty unique across repos so I made ` jbr <branchname>` that works from anywhere.

Jumping within repo. The other kink was when I wanted to focus on a particular package I’d do `j <subdir>` and it would usually be unique enough to jump to the one in my current checkout. But now I have dozens of concurrent checkouts and have to pick, even though I’m already in the repo. So `jd <subdir>` does like autojump or zoxide but only within the current checkout.

To power those shell functions I made a “where” extension for Git.

Post-event feedback showed everyone loved it. But personally I think we could have done better organizing on the co-working side so people has a more predictable schedule to lock-in.

Especially in the area of everyone sharing their personal and/or professional intentions with each other. So they're more likely to accomplish those intentions with the help of other participants.

Once a patch for a security vulnerability is public, the patch itself can reveal the vulnerability before the CVE is published. VCamper uses a staged LLM pipeline to analyze a Git commit range and flag likely vulnerability patches, even when they look like routine changes.

It’s still a proof of concept, but on known cases like curl CVE-2025-0725 it got close to the published root cause from the patch alone.

This matters because LLMs could make it much harder to keep security fixes quiet: once the patch is public, the bug may be recoverable almost immediately. Quietly shipping a fix and hoping it stays under the radar may stop being a reliable strategy.

Recently shipped this personal art project that turns daily Wordle attempts into gritty / struggle-filled stories, kinda similar to the emotional arc of the Wordle game play.

You can upload your own Wordle game screenshot to generate one for yourself.

In addition to completing what was once in the idea list, I got to learn about

- Prompt fine-tuning: Models are sharp enough to complete Wordle games quicker than human average scores, so I had to dump that down and get the average down.

- Karpathy’s Autoresearch: Experimented with auto-research for prompt fine-tuning, in addition to manual prompts.

- Vision models: While leading labs have multimodal models with quality visual reasoning, the benchmarks are still quite different for a simple Wordle analysis (reading what letters were yellow/gray/green); I also noticed labs/companies with separate vision models but their APIs lag significantly compared to what’s possible in developer experience.

- Video generation: For the last few days, I have been experimenting with automated video generation for the project's social handles. I'm still struggling with the right hooks that reduce the skip rates, but it's fun.

Similar apps have existed before (like Amie), but they were nearly all VC-backed and had pretty much all pivoted to AI (e.g. being an AI note taker). Their approaches to a Todo-focused calendar has been largely unsatisfying due to the focus on Enterprise users and whatever is trendy.

Eima, in contrast, focuses on personal use and does one thing very well: scheduling your todos. In particular, I spent a lot of time making sure multi-occurrence todos work smoothly (e.g. todos that need multiple attempts or simply recurring todos). These were not addressed by prior tools at all and had been my biggest motivation to build Eima.

Would love some test users! If you end up wanting to give Eima a try please use the code EARLYEIMA to get it for free.

Many people know that a handy data analysis feature in Excel is to create a pivot table from a spreadsheet. But spreadsheets are limited to just a million rows. You can get around this limit by jumping through a bunch of hoops.

My system lets you easily create tables with thousands of columns and hundreds of millions of rows. (Just drop a CSV, Json, or other file on a window to create a table.)

Now you can create a pivot table from it with just a few clicks of the mouse. It is fast (I created a pivot table against an 8.5 million row table of Chicago crime data in less than a second.)

The resulting pivot table is interactive. Each cell (row/column intersection) has all the row keys mapped to it. Double-click on any cell and it will instantly show you all the rows in the original table that were used to calculate the cell. You can then analyze those rows further.

It also works well against much larger tables. I have tested it out against 25M, 50M, 100M, and 200M+ row tables.

It's inspired by Zola, but has better documentation and will hopefully be more approachable when all is said and done. I'm trying to incorporate WebAssembly, with Yew, to give "islands" for high performance stuff you might want where WebAssembly makes sense. For example, I wrote search from the ground up, and built a search widget using Yew.

You can also just write JavaScript if you want.

It's a total work in progress, but I'm enjoying what I've built so far.

Making cabinets is not that hard but the industry charges insane amounts of money for it. Since I have to make cabinets for two kitchens I invested in a Sienci Labs CNC so when the cabinets are done I'll have saved money and gotten a CNC out of it which I can then sell or use for other things.

I'm not a fan of the TUI form factor for longer running, more ambitious features. Even with a classic "Add an endpoint, tweak the infra, consume in the frontend", plans get awkward to refine in markdown files, especially if everything lives in its own repo.

I wanted something like Plannotator, that could also work for the execution, not just the planning, So I've been working on something that turns Notion into the memory and orchestration layer for agents.

Underneath, it's a plan-implement-review loop, but you get a nice Notion page with a kanban board out of it. You can easily link your existing documentation, collaborate by sharing the page, annotate and comment to steer the planner, and you get versioning out of the box.

Because Notion acts as the memory, you can just open the page after a long weekend and get your agent and yourself back into the full context. You can see what's been done, what's left, or what requires human input just by looking at the board. You can ask it to fetch the comments on the pull request you raised, and it'll fetch, validate the comments, give you a report, and update the plan/board if necessary.

I've been using it exclusively for the last two weeks, I'm quite happy with it. It's been really fun to build the exact tool I wanted.

Its like a microservices architecture with NATS JetStream coordinating stuff. I want to keep the worker core as clean as possible, just managing open sockets, threads and continuation.

Document querying is something I am interested in also. This system allows me to pin a document to a socket as a subagent, which is then called upon.

I have hit alot of slip ups along the way, such as infinite loops trying to call OpenAI API, etc ...

Example usage: 10 documents on warm sockets on GPT 5.4 nano. Then the main thread can call out to those other sockets to query the documents in parallel. It allows alot of possibilities : cheaper models for cheaper tasks, input caching and lower latency.

There is also a frontend

It's a mostly vibe-coded fan site for jamtronica greats Lotus. I wrote/prompted a scraper to pull in setlist data from Nugs and have been having a lot of fun coming up with cool data analysis stuff to do with their sets.

I've seen them 7 times (chump change compared to some fans) and was starting to get certain intuitions about like, "if I hear song X that probably means they won't play song Y." For example, one of my favorite Lotus tunes, It's All Clear To Me Now, seems to fulfill a similar "function" as another song - Did Fatt.

It was pretty cool to see that intuition bear out in the data (they've only ever been played in the same show one time in over 900 total shows).

I've got a bunch of other "data" features sitting in a PR in my Gitlab, need to get around to reviewing and testing it so I can push out the next update. Also have a few other ideas for it, although I think there's probably a point coming fairly soon where there's not really anything left to do.

I posted it on the main Lotus fan group on Facebook. I have a grand total 8 users. I love those users.

The site is nothing crazy, it will never make money or anything - but it's just been a ton of fun to have something cool to hack around on.

DailySelfTrack is a customizable combination of habit tracker, health journal and diary.

It should be as powerful as a spreadsheet for self-tracking, but the daily usability should be more on par with a habit tracker app.

For example my use-case would be:

- Journaling in a way that fits into what I need. (Gratitude, bullet point jounal)

- Analysing my health and understand how things might relate to each other. (State of multiple health issues)

- Support for moving closer towards achieving my goals. (Daily focus sessions, no-phone mornings, learning Korean)

I always have growing lists of short texts, facts, and links that I wanted to host on a standalone site rather than burying them in a notes app. The workflow is simple: a browser extension to clip links with remarks, which then feeds into a public-facing list.

I’ve also added a "Substack-lite" feature. Instead of long-form writing, it lets you send simple roundup email digests (e.g., "Top 5 links this week") to opt-in subscribers.

My personal blog (wenbin.org) is currently powered by the tool.

It looks like this may only take a couple more months. I've been working on it for two months, already, and have gotten a significant amount done. The things that will slow it down, will be the usual sand in the gears: team communication overhead. Could stretch things out, quite a bit.

Right now I'm focused on the stats side. It already shows how much time you spend in each app, and I'm adding website tracking too, which should make the picture much more useful.

I'm also working on better break timing for dictation. LookAway already delays a due break if you're in the middle of typing, so it does not interrupt at a bad time. Now I'm trying to extend that same behavior to dictation as well, which turns out to be a pretty interesting detection problem because it overlaps with some of the other context signals I already use.

Most of the challenge is making it smarter without making it feel more intrusive.

Delinking is the art of stripping program for parts, essentially. The tricky part is recovering and resynthesizing relocation spots through analysis. It is a punishingly hard technique to get right because it requires exacting precision to pull off, as mistakes will corrupt the resulting object files in ways that can be difficult to detect and grueling to debug. Still, I've managed to make it work on multiple architectures and object file formats; a user community built up through word of mouth and it's now actively used in several Windows video game decompilation projects.

Recently I've experimented with Copilot and GPT-5.3 to implement support for multiple major features, like OMF object file format and DWARF debugging symbols generation. The results have been very promising, to the point where I can delegate the brunt of the work to it and stick to architecture design and code review. I've previously learned the hard way that the only way to keep this extension from imploding on itself was with an exhaustive regression test suite and it appears to guardrail the AI very effectively.

Given that I work alone on this in my spare time, I have a finite amount of endurance and context and I was reaching the limits of what I could manage on my own. There's only so much esoterica about ISAs/object file formats/toolchains/platforms that can fit at once in one brain and some features (debugging symbols generation) were simply out of reach. Now, it seems that I can finally avoid burning out on this project, albeit at a fairly high rate of premium requests consumption.

Interestingly enough, I've also experimented with local AI (mostly oss-gpt-20b) and it suffers from complete neural collapse when trying to work on this, probably because it's a genuinely difficult topic even for humans.

Official app is mobile-only and clunky, and the workflow is awkward if you're sitting at a desk. Hardest part has been maintaining compatibility across amp models. Small protocol changes or optimizations I make for one amp can break another. That means I have to do a lot of manual testing before every release. So I'm trying to think of an emulation layer or test harness I can build to make my life easier. Happy to hear suggestions there.

About ~50 people are using it so far, and main feedback has been that it's much faster and more reliable than the official app.

Lately I’ve been having LLMs implement multiple analysis methods on my session transcripts, trying to surface and identify patterns.

It’s been interesting. It took quite a bit of nudging, but Claude applied techniques I didn’t expect, from disciplines I wouldn’t have thought of.

If it works out, I’d like to turn into a sort of daemon that locally runs analysis on the sessions of users, with a privacy-preserving approach (think federated machine learning).

Would be interesting to see what patterns appear at scale, and have those confirmed or rebutted across thousands of transcripts corpuses. No reason Anthropic & OpenAI should be the only ones to benefit from that; those are our interactions after all.

One thing I find especially intriguing is how LLMs can help deal with desinformation:

- I experiment with deterministic settings of local LLMs for the document summary so that sharing a prompt would prove that the output was not tempered with (no desinformation on the service side)

- I add outputs of several LLMs (from the US, the EU and from China) for the "broader context" section so users could compare the output (no desiformation on the provider and model side)

  - immutability
  - self-hostability and/or EU SaaS option
  - nested data (e.g. nesting a list of sailing legs into a sailing trip form)
  - formulas (today(), date, string, numeric,...) and conditionals (visible/required/enabled if)

So I created two nice pieces out of that, which would have been impossible in the past due to time constraints and got massively unlocked through claude code:

  - a frontend/javascript only forms library that supports all the rendering, form schema input, data output, validation and formula/conditional logic
  - a multi-tenant SaaS product, that is a single golang binary and stores in sqlite, easily self-hostable but I can also operate it as a European SaaS (and in other regions) where needed

So I was trying:

  - pocketbase
  - really running something bigger with much more data off of sqlite (primarily used it for smaller stuff in the past)
  - real focus on self-host-ability, keeping dependencies minimal and extremely simple (which also helps claude)
  - trying other tools for security scanning, verification, testing, security analysis, WAF,... than I use at work, pretty much playing around with tech as much as I can to see new and different stuff :-)

  1. Plan review & iterative feedback. 

  2. Now code review with iterative feedback.

At the moment working on the 3rd party development tools so in the future anyone can make their game dev dreams a reality and make a simple and fun multiplayer party game for the Gaming Couch platform, ideally in only one weekend!

If you're an interested game dev that would like to beta test the dev tools, hit me up either here, via Discord (link available from https://gamingcouch.com) or by emailing me at gc[dot]community[at]gamingcouch[dot]com!

The TL;DR of Gaming Couch:

- Currently in free Early Access with 18 competitive mini-games.

- Players use their mobile phones as controllers (you can use game pads as well!)

- Everything is completely web-based, no downloads or installs are necessary to play

- All games support up to 8 players at a time and are action based, with quick ~one minute rounds to keep a good pace. This means there are no language based trivia or asynchronous games!

Data engineer, 20 yrs software / 10 in ag-tech. Picked up beekeeping and was surprised how much structured data a single inspection produces, and how nowhere useful exists to put it. It's a gloved, veiled, honey-and-propolis-covered activity. Tapping through a mobile UI mid-inspection is not ideal, and good luck getting your phone back clean.

The core is a virtual hive model. It's all mutable state: boxes, frames, components, queens, and colonies you rearrange to mirror the physical yard. Treatments, feedings, and inspections layer on top.

This summer I'm shipping voice-driven inspections: narrate what you see frame by frame, STT + LLM pipeline extracts structured data and maps it to your hive model.

If you have beekeeping friends, I'd love it if you could send it along <3. I won't claim it has every feature under the sun, but I work on it every day and have a strong roadmap ahead.

Also open to critiques. Thanks!

(Don't mind the errors or display issues for now; this project will report which versions of programs are installed on the given computer, and which ones could be updated. A few smaller bugs still remain but the main rewrite was finished now.)

For work-related reasons I have to expand on some python tasks in the coming weeks. Trying to find something interesting here, but I guess I'll just focus on various bioinformatics-related tasks (also related to work). Programming for the most part is not extremely interesting - the only part I actually like is any creativity and useful end results. Fixing bugs is annoying to no ends. Writing documentation is also boring, but can not be avoided.

My motivation for creating CompterPoker.ai was feeling a bit overwhelmed by some of the professional poker tools out there for learning GTO play. For some tools, learning how to simply operate the tool itself felt like a second job. With ComputerPoker.ai players can play against bots themselves simulating GTO play to learn what it "feels like" to play GTO vs. GTO opponents without having to turn any knobs or dials (feedback is real-time as you play).

The Beta tester code for HN Users is: HackerNews2026. All feedback is welcome! Please send suggestions for improvement or bugs to contact@computerpoker.ai or alternatively leave a comment below. Any questions I will do my best to answer.

As for the product offering the website is designed to teach players how to play optimal poker strategy (GTO) in simulated Texas Hold 'Em poker tournaments. Our value proposition is that if you can consistently beat the bots then you will fare well in live poker tournaments (of course adjusting for your opponents' play).

In addition to GTO pre-flop quizzes and pre-flop charts, users have the ability to simulate poker tournaments from start-to-finish and get feedback on their decisions _in real-time_ in a fun and low-risk environment.

For those interested the tech stack is Django deployed on AWS via Terraform and SaltStack, the database uses a Postgres RDS backend, and the frontend uses HTMX with WebSockets via Django Channels and Redis (Nginx serving as reverse proxy with CloudFlare DNS and SSL). During the project I used Claude Code to aid with various boilerplate aspects of the code base including building out the repos for Terraform and SaltSack and of course speeding up Django development.

Users are graded pre-flop based on the covered pre-flop scenarios (two-ways only for now). Post-flop users are graded on a residual MLP PyTorch model. We have built an in-house solver in Rust using the discontented CFR++ algorithm. The PyTorch model approximates GTO play post-flop (again only two-ways currently) based on training data with raises, EV, and realistic ranges for OOP and IP players. Because the post-flop decisions are based on a model that will always be a work in progress I refer to these decisions as GTOA (or "GTO Approximate").

Version 8 of the PyTorch model is the first one that I am happy with and actually find it quite difficult to play against. If you manage to beat the bots please do let me know how many tries it took! For those curious the PyTorch params for the most recent run are below (I trained on a gaming PC via Linux WSL2 using an AMD GPU).

The website is live in Beta mode as I gather feedback on how things are structured and work out any bugs/kinks. If you have any suggestions for improvements I’d love to hear them. Subscriptions are live so if anyone wanted to test the Stripe payment processing flow I certainly wouldn’t mind! ;-)

p.s. This is a side gig for me. I am currently looking for full-time work either fully remote or on-site based in London, UK (this LLC that runs ComputerPoker.ai operates out of USA but I am based full-time in the UK and authorized to work in both UK and USA). If you or someone you know is looking for a SRE with strong software engineering skills please let me know!

Simracing trainer.

I love simracing, I'm moderately competitive and want to improve, and I like to be efficient with my practice. So having access to and using a lot of telemetry, I noticed that the "turn a few laps, load telemetry, compare against reference lap, try again" is not as efficient as it could be.

Also a lot of my telemetry analysis is very rote and "rules based": Look at the biggest laptime delta jump against reference, try to determine the cause among a few usual suspects".

So I have started experimenting with a system that reads the iRacing telemetry in real time, and compares against the reference telemetry live, finding the biggest delta jumps, and trying to find the root cause of the time loss using an increasingly sophisticated GOFAI rule and pattern matching system. Then this report is fed to a cheap LLM call to be condensed into clear advice, and the result goes to the free Microsoft TTS API. So I get instant feedback of where I'm slow and maybe even why.

So far I fear it's mostly making me faster from all the test laps involved more than the advice itself, but when it clicks it does feel magical and really help.

But sometimes I feel like I'm just speedrunning the collapse of 70s AI, as it feels a bit too brittle and situational.

I also have added additional tools for tracking improvement across sessions, finding statistically problematic corners (where am I plain bad?, where am I inconsistent?) or even training my muscle memory by tracing fast driver brake traces using my pedal.

Yay compiler: The other ongoing thing is a clean room reimplementation of Jon Blow's Jai. I've been curious about the language for years, but it's a closed beta and for some reason I've never felt about asking Jon to get into it. I'm not really a game dev so I wouldn't even know what to put in the request.

So now I have 100k+ lines of Rust that can compile a very significant subset of the publicly available Jai source code. I just used various LLMs to condense the public information about the language and come up with a dev plan and started chipping at it. Once I had something in a kind of working state I started with the Way to Jai big tutorial and make sure every example there compiles and works as intended, fixing errors or missing features one by one.

I mostly use Claude Code or Codex, but sometimes what I do is having them guide me into the new feature and doing the edits myself while they explain, so I get to know how things really work under the hood.

It's a silly pointless project, but for some reason I find very satisfying watching it compile the examples.

I deliberately separated it from my public internet persona (which is connected to my real name) in the hopes that I could write about weird, woo-y, or controversial topics without worry. I've got a few articles half baked and have been having fun engaging with a different subset of the Substack crowd than my normal tech focus would show me.

Of course the stats show that the one article I did that touches on AI has done an order of magnitude better than anything else.

Anyway this is just kind of a weird sideline project, a sort of release valve for stuff that wouldn't fit in on my "professional" site, but it's been a fun thing to spend some time on.

Another thing that's cool is that I largely stopped _writing_ a few years back. I always enjoyed writing but of course as a dev most of my stuff had a technical/tutorial bent to it. Writing weird little "what do I think" essays has forced me to exercise a writing muscle I really hadn't stretched for a long time and I've enjoyed it.

There's only a handful of things up now, it's nothing special really. Link in my bio, if you see something you like I would love to hear from you!

Some months ago, I saw that very popup, and finally started working on something I've been wanted to do for a long-time, a spreadsheet application. It's cross-platform (looks and work identical across Windows, macOS and Linux), lightweight, and does what a spreadsheet application should be able to do, in the way you expect it, forever. As an extra benefit, I can finally open some spreadsheets that grown out of control (+100MB and growing) without having to go and make a cup of coffee while the spreadsheet loads.

I don't really have any concrete to share, I guess it'll be a Show HN eventually, but I thought it was funny it was brought up in a similar way in that article as was the motivation for me to build yet another spreadsheet application.

Six months ago, that would have been unrealistic, because we're heavily committed to the mongodb API and we make it part of our own API.

Starting in December though, Opus 4.6 made it perfectly realistic to pursue this with Claude Code as a series of personal weekend projects.

Now, despite not having any official resources on this until the last week or so, it should land in May.

This doesn't work for everything. It absolutely helps that the problem I'm solving is an "adapter pattern" problem: "make X talk like Y." And that we have a massive test suite, at multiple levels. That combination makes "here's the problem, go solve it, grind until the tests pass, don't bother me for a few hours" a realistic AI agent request.

But it's a little mind-blowing all the same. The hype around AI is so out of control, it can be easy to miss genuine "holy crap" moments.

Along the way I've written a fair bit about how to run Claude Code autonomously on your household server in a reasonably secure manner:

https://apostrophecms.com/blog/how-to-be-more-productive-wit...)

Also general Claude Code tips and thoughts on workflows that help and workflows that ultimately just speed your burnout:

The goal is to make every recipe foolproof on the first try, similar to when you walk into a restaurant and just pick what you want to eat without thinking about the details. The goal is to have the same experience, just pick what you want to eat, with recipes that tells you exactly what to do with no magic involved.

Technically it is probably very different from other recipe apps. The database is a huge graph that captures the relations between ingredients and processes. Imagine 'raw potato'->'peeled potato'->'boiled potato'->'mashed potato'. It is all the same ingredients but different processing. The lines between the nodes define the process and the nodes are physical things. Recipes are defined as subsets of the graph. The graph can also wrap around into itself, which is apparently needed to properly define some European dishes in this system. The graph also has multiple layers to capture different relationships that are not process related.

Why was it designed it in this way? Because food/cooking is complex to define. This design is the only way I have found that can capture enough of these complex relationships that the computer can also 'understand' what is going on.

My favourite thing about this is that each recipe is strictly defined in the graph. If the recipe skips a step, or something is undefined, the computer knows that the recipe is incomplete. It won't ask you to do 10 things at the same time and then have something magically appear out of nowhere. It is like compile time checking but for recipes.

It also enables some other superpowers, for example: • Exclude meat part of the graph = vegetarian. Same thing works with allergies. • Include meat part of graph = only show me recipes that contain meat. • Recursive search: search for 'potato' and the computer will know that french fries are made from potato. It can therefore tell you that you could make the hamburger meal, but you will need to complete the french fries recipe first, which should take 60 minutes. • Adjustable recipe difficulty (experimental): It knows which steps can be done in parallell, and which can't based on how the nodes connect. A beginner can get a slower paced recipe with breathing room between steps, while someone more experienced can do a faster pace and do more things in parallell.

If I knew what it would take to build this, I would never have gotten started. I completely underestimated the complexity of the problem I was trying to solve. But here we are, and now it is basically done and working.

The website captures the key points from a non-technical point of view, and you can enter your email and get notified when it will launch in your country.

I think in this era of coding agents, more people feel empowered to build their own workflow automation. But for vast majority of non-technical folks, Claude Code or even Replit are not easy to use solutions. So I am taking inspiration from spreadsheets and using that as the primary UX to build a coding agent.

I started this after volunteering at my kid’s tournaments and seeing how fragmented things are: • registrations in Google Forms • payments via Venmo/Zelle • pairings in SwissSys/WinTD • communication across email and text

Chess67 aims to unify that: • coaches can sell lessons and manage scheduling and payments • clubs can run events and communicate with players • tournaments can handle registrations, with pairing and USCF submission in progress

Still early. The main challenge is not building features but matching existing workflows, especially Swiss pairings, which are more nuanced than they look.

It's an LLM-webapp-builder, sure, but different from the rest! I have the LLM write python code when it needs to modify an HTML file for example (it'll use beautifulsoup; then I run the code: it parses the source into a data structure, modifies the data structure, and then outputs the resulting html).

It's also a marketplace where you can publish your llm-powered webapp, and earn $ on the token margins (I charge 2x token rates) when people use your site.

The idea: describe any problem in plain language (voice or text), and AI codifies it into a structured program with the right people, steps, timeline, and agents to get it done. It's a 5-step wizard: Define Problem → Codify Solution → Setup Program → Execute Program → Verify Outcome.

It runs across 50+ domains — codify.healthcare (EMR backend), codify.education (LMS backend), codify.finance, codify.careers (HRM backend), codify.law, plus 13 city domains (codify.nyc, codify.miami, codify.london, codify.tokyo, etc.). Each domain tailors the AI assessment and program output to that sector.

The platform is Project20x — think of it as the infrastructure layer. If Codify is the verb ("codify your healthcare problem into a care program"), Project20x is the operating system that runs it all: multi-tenant governance, AI agent orchestration, and domain-specific sys-cores for healthcare, education, city services, etc.

Every US federal agency and state-level department has a subdomain — ed.usa.project20x.com (Dept of Education), doj.usa.project20x.com, hhs.usa.project20x.com, etc. — with AI agents representing each agency's mandate. Same structure at the state level.

The political side: Project20x hosts policy management for both parties — dnc.project20x.com and rnc.project20x.com — where legislative intent gets codified into executable governance through a 10-step policy lifecycle. Right now I'm building out the multi-agent environment so agency agents can negotiate with each other, make deals, and send policy proposals up to the HITL (human-in-the-loop) politician for approval. Each elected official has a profile (e.g. https://project20x.com/u/donald-trump) where constituents can engage and where policy proposals land for review.

The name is a nod to structured policy frameworks, but the goal is nonpartisan infrastructure: democratically governed essential services delivered as AI-native social programs.

Stack: Nuxt 2/Vue 2 frontend, Laravel 10 API, Python/LangGraph agent orchestration, Flutter mobile app. Currently live across all domains.

Direction - I’m trying to teach people how to do all the other stuff that you need to know, other than writing code, about delivering real products and not just a bunch of junk and slop that can’t be maintained

ShowHN: https://news.ycombinator.com/item?id=47721469

I’m also trying to make it really super simple so it’s week to week pricing, and have a discord community that grows out of it.

It’s literally just four two hour courses on Monday of each week and a demo day.

you walk through what you’re gonna do, how you’re gonna do it, how you’re gonna use your AI assistants to help you, where it can help you, and where it can’t help you, how to talk to it about teaching you instead of just doing it for you, and at the end of it you have something tangible to show for it.

There’s no subscription this is just straight up teaching product and project development that comes with a community and the community grows as much as it chooses to.

You can read the vision and roadmap on the site as well

Over the past few weeks, I have been building an AI coding tool in Go. The core loop is straightforward: accept a natural-language instruction, let the LLM interpret intent, then execute coding work through tools such as file read/write, code search, and terminal commands.

As of now, I haven't come across any agent coding tools written in Go, but I have always thought that Go is an excellent language and is very suitable for building any CLI tools.

Currently, I have added harness constraints to the agent by exposing hooks and implementing monitoring during the agent's working lifecycle. I think this will enable a clear division of responsibilities between the agent and the harness. The agent is the smallest execution core, while the harness acts as the execution agent for the agent and imposes constraints on its behavior.
