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

josters• 7 months ago

Working on updating my Your-Age-in-Days app[1] for iOS 26. The main motivation was to have the days I've lived always available on the lock screen with a more native feel than the workaround I had before (nightly Shortcut which updates the background image and adds the current number as an overlay to it).

A side project for my side project: I built my own static site generator with React islands architecture and MDX support, using Bun. (Build your site from .mdx files, output only html+css, progressively hydrate the client with React only as needed).

I wrote about it here: https://pcmaffey.com/custom-ssg/

Forkable template: https://github.com/pcmaffey/bun-ssg

mmarian4• 7 months ago

I'm curious if you've considered using Astro? It's my go-to for that use case, been using it for all my side project sites.

pcmaffey2• 7 months ago

From my post:

Staring at the errors in my CLI, I realized I did not want to use another framework. It's why I had already discarded the idea of switching to Astro. Twiddling around someone else's abstractions and incentives, frustrations fitting together the final 20% of a project... I've been down that road too many times before. It's never fun. The tradeoffs _you don't know you're making_ are the biggest risk.

I've recently been working on developing an MCP on top of Libreoffice Draw and I just learned what an amazing piece of software the whole Libreoffice suite is, I would definitely be trying to use it more and I will take a look at your extension. Thanks for sharing!

mmarian4• 7 months ago

It is! My only struggle is with the extension development/documentation. It was a pain to get my sidebar appearing in the toolbar, and I'm afraid to touch any of that code I wrote.

How are you going about learning about the LibreOffice APIs?

nick4• 7 months ago

I've really enjoyed writing blog posts recently. Not only is it a great way to flex your writing muscles, but writing about a topic, unsurprisingly, helps you understand that topic better too. I've had great conversations with friends about the posts I've written as well.

And sort of in that same vein, I've been developing my own static site generator that I eventually want to move my blog to. It's almost certainly going to be a worse SSG than every alternative, but it'll be mine and that's worth something in itself.

Plus it's just been fun to make! I wrote some gnarly code to generate infinitely nestable layouts that I'm kind of proud of. It's the kind of code that's really cool but you can only code on a project for yourself, because if someone else had to debug it, they might say some pretty unkind things about you.

hamiecod12• 7 months ago

I agree with you about writing. Back in 2020, I made a commitment to study a CS or math topic in detail each week and then write an essay about it. Those were some of my best learning experiences and when I look back at those essays, they are pure gold.

I built a free USCIS form-filling tool (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.

https://fillvisa.com/demo/

What Fillvisa does:

- Fill USCIS forms directly in your browser - no Adobe needed

- 100% free

- No login/account required

- Autosave as you type

- Local-only storage (your data never leaves the browser)

- Clean, mobile-friendly UI

- Generates the official USCIS PDF, ready to submit

- Built-in signature pad

I just wanted a fast, modern, free way to complete the actual USCIS form itself without the PDF headaches. This is a beta version

araes8• 7 months ago

Feel like a Reddit bot, yet USCIS is "United States Customs and Immigration Services". The forms list that's probably of interest are found at:

That list is quite exhausitve. I decided to pick the most frequently used forms. I referred https://citizenpath.com/uscis-forms/ and picked their list ;)

oidar2• 7 months ago

Is this API only, or can a person use subscriptions (like claude max)?

otekengineering2• 7 months ago

It uses your existing subscriptions and supports all the major CLI and API providers. There's no cloud features of Omnispect itself, it runs locally except for calls to the LLM providers.

Claude Opus 4.5 is used as a routing agent, which selects the most appropriate LLM provider and model tier to delegate a task to. For example, the routing agent might delegate a single large task to GPT-5, which in turn delegates multiple small tasks to Haiku agents in parallel, then Gemini reviews all the work.

Omnispect lets you view the delegation tree of prompts and responses that spawn from your initial prompt.

I'm working on a meta framework for building "full-stack" libraries. I.e. libraries that bundle frontend hooks, backend routes, and a database schema into a single package.

This allows library authors to do more, like defining webhook handlers and (simple) database operations. The idea is to move complexity from the library user to the author, making (API) integrations easier.

I think libraries being able to write to your database is a pretty powerful concept, and can enable a number of interesting use cases.

I’ve been working on "Next Arc Research" — https://nextarcresearch.com - a wrapper around my curiosity to understand how AI, compute, and capital might change markets by 2030.

It’s not a trading tool or product. More like a weekly, machine-assisted research project. Each cycle I run analyses on 120+ public companies across semiconductors, cloud, biotech, energy, robotics, quantum and crypto. The framing is inspired by Emad Mostaque’s “The Last Economy” thesis — the idea that when intelligence becomes cheap, the physics of value creation start to look very different. I originally built it for myself and retail investors in my family but I figure it could have more general utility so prettied it up a bit.

The system uses large-model reasoning (GPT-5+ though I've also tested Sonnet, Gemini and Grok) combined with structured scoring across technology maturity, risk, competitive positioning, and alignment to AI-era dynamics. The output is static HTML dashboards, PDFs, and CSVs that track month-over-month shifts. I'm adding to it weekly.

Mostly I’m trying to answer questions like:

* Which companies are structurally positioned for outsized upside in The Last Economy?

* How should I deliver the research so that it would have been actionable to someone like me 30 years ago?

* What signals would help folks identify “the next NVIDIA” 5 years earlier?

The inference costs real $$$ so I've set up a Patreon that, hopefully, will allow me to scale coverage and extend the modelling and methodology. There is a free tier and some recent, complete example output on the web site. I'm also happy to gift a free month for folks willing to provide constructive feedback: https://www.patreon.com/NextArcResearch/redeem/CC2A2 - in particular I'm looking for feedback on how to make the research more actionable without drifting into "financial advice".

I don't collect any data but Patreon does for authentication and Cloudflare does to deliver Pages. The Last Economy is here: https://ii.inc/web/the-last-economy

Want to put local history on a map, so when I go somewhere I could ideally just open this webapp and immediately get presented with cool or interesting history that happened close by.

Currently spending time establishing relationships with historical societies, as I really need them to contribute points of interest, and stories. Many of these societies are run on a voluntary basis by 70+ year olds, so it's a long process. Getting some good responses eventually though, so it might actually go somewhere, just a lot slower than I want.

Also still doing https://wheretodrink.beer, but haven't added anything of note since playing on this other project.

And react2shell was a blast

Oh, thanks for the interest, but I'm not that far along yet. I have a bare bones alpha, but it's not ready for the internet just yet. I also haven't secured the domain names so I won't be sharing any code names :)

This is so very silly, but the only way I have to collect emails for people interested in the progress, beta testing or final version, is on my beer page.. So I created a page for the world's most obscure / smallest city and if you want to be updated you can register there - https://wheretodrink.beer/in/croatia/hum-75gkn - The registration is under "Stay informed about updates in Hum?"

If anyone signs up I'll manually move you out of that list and into the "local history" waitlist.

Custom Copilot alternative / extension because I no longer believe it is a good idea to let Big Ai determine how you write code with your new helper. Big Tech f'd up a lot of things the last 25 years as we ceded control of our interfaces to them. I don't want to make the same mistake with my primary work tool.

2. Hof is already an established open source project, the goal is to interweave

3. Freedom to explore and design my own experience. Joining another project has never afforded this.

Building the most effective typing application

https://typequicker.com

This is something that started as a passion project - I wanted to see just how effective of a typing application I could make to help people improve typing speed quickly.

It’s very data driven and personalized. We analyze a lot of key weak points about a user’s typing and generate natural text (using LLMs) that target multiple key weak points at once.

Additionally we have a lot of typing modes.

- Code typing practice; we support 20+ programming languages - daily typing test - target practice; click on on any stat in the results and we generate natural text that uses a lot of that (bigrams, trigrams, words, fingers, etc).

mamouri2• 7 months ago

I’ve tried it and really enjoyed how it works. I’d like to suggest a small UX improvement: for a typing app, it would be much easier to avoid using the mouse. When a practice ends, the user should be able to press the RETURN key to move to the next practice. (instead of clicking the Continue button)

absoluteunit12• 7 months ago

Hey - thanks for trying it out :)

That's a good point - we actually do have keyboard shortcuts but their discovery is definitely lacking! Using the return key as the default seems more intuitive - thanks for the suggestion!

djfobbz5• 7 months ago

I'm working on an affordable SaaS platform for small and mid-sized fabrication shops across the US and Canada. It automates quoting and production for sheet-metal and CNC jobs and can handle pretty much any CAD format, even full assemblies. On the AI side, we've got a mix of models doing the heavy lifting: a tuned geometric transformer for feature detection, a graph neural net for topology, and a vision model for mesh segmentation. All that ties into our custom CAD logic for geometry parsing, 2D nesting for laser/machining, and 3D nesting for forming and packaging. The whole idea is to level the playing field so smaller local shops can compete with the big instant-quote guys without needing an in-house dev team.

zkmon• 7 months ago

This sounds interesting. Are you using any CAD software for this? Can the fabricator create their own design?

djfobbz5• 7 months ago

No, we aren’t using any CAD software for this since we’re not trying to be in the design space ourselves. Instead, we’re using libraries like OpenCascade’s Mesh Toolkit to read and tessellate CAD files into a hybrid 3D format optimized for web rendering, while preserving precise geometry, topology, and manufacturing data.

skilldeliver• 7 months ago

interesting, send a website

abdullahkhalids10• 7 months ago

I can't tell how you allow the small shops to make instant-quotes. Is it because they can instantly visualize the part? Or do you process the customer's design and provide the shop additional information that helps them do this? Or are you just generating the final quote itself already based on what you know about the shop and the customer design?

djfobbz5• 7 months ago

Good question! Right now we’re starting with the sheet metal side of things: laser cutting, forming, welding, surface finishing, and final touches like anodizing, powder coat, or just a clean mill finish. The platform takes the customer’s CAD file, runs DFM checks, figures out material usage, laser time, bend complexity, and weld length, then instantly generates a production-ready quote based on each shop’s own pricing and capabilities. This quote includes delivery cost + an estimated time you can expect the part. There’s 2D and 3D visualization built in, but the real magic is the drag-and-drop, get-an-instant-quote experience. The reality is, most fab shops are still painfully slow when it comes to quoting. Even in 2025 it’s not unusual to wait a week (or three) just to hear back. That’s the gap we’re closing.

buildcaptive2• 7 months ago

Got a link to a landing page?

bruckie• 7 months ago

Is is essentially a SaaS version of what businesses like OSH Cut and SendCutSend have built? And are you doing just the quoting, or full shop management?

djfobbz5• 7 months ago

That's exactly what it is. But instead of keeping it as some proprietary tool for one shop, our goal is to make that same tech accessible and affordable for all shops. Not every fab shop is tech-first, and that's totally fine. We're building something that helps them compete without needing a full-time developer or a six-figure software budget.

As for your last question, we're not trying to replace any existing ERP or CRM systems. We're focused on delivering instant, accurate quotations through our own turnkey pricing model that helps job shops stay competitive day-to-day, manage payments seamlessly, and give customers real-time shipping options or an easy Will Call pickup if they're local.

Feels like I'm working on a million things (between work, side contracts, and creative explorations). Recently a friend asked whether AI is helping or hurting my workflow.

And I realized I couldn't give a concrete answer. Lots of speculation, but I realized I didn't have hardly any real data. Inspired by Adam Grant's work on "rethinking", I'm _currently_ writing a tiny CLI to run self-experiments on my own productivity, auto-checking in / observing commits/code changes.

Goal at the end is to be able to test myself across different dimensions with "no AI", "moderate AI" (e.g. searching, inline assist), and "full AI" (agents, etc). https://github.com/wellwright-labs/pulse

Building pyreqwest, a high-performance Python HTTP client backed by Rust’s reqwest. It has gotten quite feature rich: async and sync APIs, similar ergonomic interface of reqwest, full type hints, and built-in testing/mocking. It has no unsafe code, and no Python-side dependencies. (Started after getting too annoyed with all the issues httpx has.)

sirfz2• 7 months ago

I've recently updated an internal tool which basically acts as a configuration and dependency/context manager for performing hundreds of api calls. I added an httpx backend (to test vs the current urllib3 backend) and also introduced an async API (httpx as well). However, from your benchmarks it seems like I should've went with aiohttp for faster async? I will work on integrating pyreqwest as well

Yes httpx is badly broken. Eg its connection pooling implementation is not great at all. There are various issues in httpx/httpcore. There are also old open PRs trying to fix issues but maintainer(s) are just not intrested.

If you have played military sim (Milsim) games like Project Reality, Squad or Arma you might appreciate it.

Its quite cool how the game devs have made a lot of tooling to use; they use Typescript to hook into in-game events and functions.

There is a whole community making lots of content too:- https://bfportal.gg/

Currently I am working on an insurgency game mode; where one team has to defend some caches and use guerilla tactics, whilst the other team has a smaller size but the advantage of firepower and vehicles.

Hopefully have it released by Christmas time.

I was into playing the mods for the original and played some of 2142 on PC.

Has the official multiplayer gameplay held up? I did try a release around the time of RDR2 on Xbox and it had seemed like pay to play may have messed with it at some point.

Curious if the mod support seems like a jailbreak from the official multiplayer.

I'm working on building out a microservice ecosystem on OCI. I'm not formally educated so I just sort of stack things up and tear them down. I hardened my server and I am running dockerized services. I'm also running a web server that hosts the very start of my long-term personal site. It's been pretty challenging, illuminating, and down right fun. I've been putting down the controller for a terminal!

Seriously, I'm very proud of myself for the little I've accomplished so far. I don't have friends in tech so I don't get to talk about it or bounce ideas off people.

Thanks for letting me get that out!

Working towards a handheld computer with a physical keyboard. Lots of examples out there (Hackberry Pi, Beepy, etc) but wanted to try my hand at it.

Along the way I found most of these use salvaged BlackBerry keyboards which are only going to become harder to find, so also on a bit of a side quest to build a thumb-sized keyboard from scratch. Got me into laying out and prototyping my first PCBs and learning about how these things are made - lots of fun so far!

Something cool I learned from tearing apart a BB keyboard: the satisfying “click” is just a tiny metal dome that pops and completes the circuit when pressed. Not news to anyone familiar with electronics manufacturing, but it was a cool thing to “discover.”

I’m still exploring new forms of AI-powered learning tools.

The latest thing I’ve been working on is an adaptive mode inspired by the LECTOR paper [1]. Where each lesson is a single learning concept with a mastery score tight to it based on your understanding of the said concept, so in principle the system can reintroduce concepts you didn’t fully grasp later on, ideally making separate flashcards unnecessary.

It can be self-hosted if any one want's to give it a try!

Building a little extra tool for my reservation system, which simulates guests reserving accommodations before a customer launches. This is nice if you have no idea how users will respond to your availability and options.

We have an ML model that's trained on real reservations and use an LLM to decide why a user mightve opted out. We apply personas to this LLM to get a bit of a sense how they would probably be operating the booking flow.

As a means to learn about both WebAssembly and Rust, I started writing a WebAssembly binary decoder (i.e. a parser for `.wasm` files) from scratch.

Recently it hit v2.0 spec conformance. 3.0 is next on the roadmap. (I'm executing it against the upstream spec test suite.)

I don't plan to make it a highly-performant decoder for use in production environments, but rather one that can be used for educational purposes, easy to read and/or debugging issues with modules. That's why I decided not to offer a streaming API, and why I'll be focusing on things like good errors, good code docs etc.

https://github.com/agis/wadec

P.S. I'm new to the language so any feedback is more than welcome.

zephen5• 7 months ago

This is cool.

I started to look at the wasm stuff, but all the documentation I found was so high-level as to be meaningless.

What do you recommend for someone who would want to be able to create or read .wasm files?

pasxizeis2• 7 months ago

I'd say jump straight to the specification (maybe v2, which is simpler).

But I occasionally saw one or two articles around where they explain how the binary format works, which could be a good introduction before jumping to the spec.

A Python ORM, inspired by Drizzle and the like. Whenever I come to Python I'm frustrated by the ORM options. They generally lack type-safety on inputs and outputs, or useful type hints.

SQLAlchemy is an institution but I think it's hard to use if it's not your full-time job. I check the docs for every query. I want something simple for the 80-99% of cases, that lets you drop easily into raw SQL for the remaining %.

I'm going to keep hacking at it, would love to from anyone who thinks this is worthwhile (or not). Also: - The interface for update queries is clunky. Should I add codegen? - Should I try to implement a SQL diffing engine (for migrations). Or just vendor sqldef/similar...?

Overly specific LLM research into KV cache eviction.

The vast majority of tokens in a sequence will be irrelevant to an attention mechanism outside of a very small window. Right now however we tend to either keep all cache values forever, or dump them all once they hit a certain age.

My theory is that you can train model to look at the key vectors and from that information alone work out how long to keep a the token in the cache for. Results so far look promising and it’s easy to add after the fact without retraining the core model itself.

I am still plugging away at https://threeemojis.com/en-US/play/hex/en-US/today , a daily word game for language learners.

Since hacker news last saw it, it’s been translated into English, German, Spanish and Chinese. If, say, a Chinese speaker wanted to learn more English words, then they could go to https://threeemojis.com/zh-CN/play/hex/en-US/today and play the game with English words with Chinese definitions and interface. This is the first cross language daily word game of its kind (as far as I know), so it’s been a lot of fun watching who plays which languages from where.

The next challenge that I’m thinking about is growing the game. The write ups and mentions on blogs add up, the social sharing helps, but I’d really like to break into the short form video realm.

If you read interviews from other word game creators, every successful game has some variation of got popular riding the wordle wave, or one random guy made a random TikTok one time that went super viral, and otherwise every other growth method they have tried since then hasn’t worked that well and they are coasting along.

So, sans another wordle wave, I am working on growing a TikTok following and then working on converting that following into players, a bit of a two step there, but that’s how the game is played these days. https://www.tiktok.com/@three_emojis_hq for the curious. Still experimenting and finding video styles and formats that travel well there. Pingo AI and other language apps have shown how strong TikTok can be for growth, so I think there’s something there. That’s all for this month!

It can, if you want, also replicate the actual data in the source DB but with automatically anonymized PII data.

It can replicate a DB in as little as 9 seconds.

Creating Daino Qt - a collection of components that makes Qt apps feel and look native on both Desktops and mobiles (each with its own set of challenges).

Developing Qt apps with C++ and QML is a blast - the fast performance of C++ and ease of use of writing UI in QML. But there is so much left to be desired with the built-in Qt Quick components - mobile issues like non native text handling, non native swipe-able stack view and much more. I’m aiming to bridge that gap.

I'm working on porting KiCad to the browser. It's a lot of sweat and tears, multithreading issues and some more sweat. I've updated a port of WxWidgets and now I support all the features KiCad needs with ~200 tests.

Right now I have a build that loads in the browser, but I really want to have "multithreading" which means workers in the web. One can use asyncify with emscripten to translate blocking C++ to WASM, but that transition is not perfect, right now I'm debugging a bug where there's a race condition that halts all execution and the main thread runs in an infinite loop waiting for the workers to stand up. I guess I'll have a few of those ahead.

The main goal is to 1. just have fun 2. use yjs as a collab backend so multiple people can edit the same PCB. This will probably work with pcbnew, KiCad's layout editor, since it has a plugin system and AFAIK I can do the sync layer there. For the rest ( schematic, component editor etc. ) I'll have to figure out something.. KiCad does not sync automatically if you modify a file, I'll have to do some lifting there.

Anyway, it's a lot of fun, I really want this thing to exist, I'm hoping that I won't run into a "wellll, this is just not going to work" kind of issue in the end.

I've been taking some time off from https://gethly.com, as majority of functionality I wanted to implement and offer to customers is done, so it's mostly just some tweaks here and there.

I was pondering doing something in regards to decentralised consummation of content. I am beginning to see how various websites are walling off their content and centralising everything whilst also monetising access to it for themselves and kicking content creators out, forcing them to run their own websites and use multiple backup platforms(mostly the dying youtube).

So I was thinking about flipping it on its head and instead of going to different websites to consume this content, like youtube, twitter and whatnot, people would have a single program to aggregate it instead. Then it occurred to me that this is what RSS/Atom was made for, kind of. So I am just letting the idea marinate for a bit and maybe next year I will look into it. Mastodon might have some good concepts in it that I want to look into and also come up with some standardised way for richer content that creators could provide beyond RSS to make it more palatable and easier consumable for users.

tl;dr not much this month :)

Building Contextify - a MacOS application that consumes Claude Code and Codex transcripts, stores them in a local sql db.

The main window uses Apple’s local LLM to summarize your conversation in realtime, with some swoopty UI like QUEUED state on Claude Code.

I’ve just added macOS Sequoia support and a really cool CLI with Claude Code skill allowing seamless integration of information from your conversational history into aI’s responses to questions about your development history.

The CLI interface contract was designed to mutual agreement between Claude code and codex with the goal of satisfying their preferences for RAG.

This new query feature and pre-Tahoe support should be out this week, but you can download the app now on the App Store or as a DMG.

I’m very excited about this App and I would love to get any feedback from people here on HN!

That’s an interesting direction. I haven’t thought of this in multiplayer sense.

Would you see this as something that is sort of turn-key, where a central database is hosted and secured to your group?

Or would you require something more DIY like a local network storage device?

And similarly would you be open to having the summaries generated by a frontier model? Or would you again need it to be something that you hosted locally?

Thank you for the feedback and interest.

Once I can get any Lemmy and a Mastodon client working, I will then start changing their own SDKs, and then I can replace calls from their application-specific APIs with direct calls to Linked Data server.

I'm working on "Cargo but for C".

It started out as something marginally more useful than vendoring your dependencies as submodules + baking in the knowledge of how to build a bunch of common projects.

I realized, though, that there was somehow a huge gap in the insane world of C build tools. There's nothing that:

- Lets you pin really precisely and builds everything from source (i.e. no binary repository)

- Does not depend on either a scripting language or a completely insane DSL (Conan uses Python, CMake is an eldritch horror, ditto Make, lots of other tools of course but none of them quite hit the mark)

- Has a good balance of "builds are data" and "builds are code".

Anyway, it's going great. There are, of course, a ton of problems to solve. Chief among them is the obvious caveat that C is not a monoculture like Rust. There will be zero upstream libraries that use this tool natively. But I don't think it matters. I think I can build something which is as much better to the existing tools as, say, UV was to existing Python tools, even with that disadvantage.

Me too! It's pretty good. Unfortunately, it depend on Python. Not that Python's that bad. It's just that it's completely bonkers to me that building C, the most fundamental language that's commonly written today, the language that every other language has an FFI for and three quarters of them either are written in or were bootstrapped with a version written in -- that this language depends on PYTHON to build!

It's crazy, and I understand why it's the case, but I know how to fix it and I'd like to have a crack at it.

Nice stuff! I'm keen to see this too.

I love programming in rust. Lots of non-rust developers think the whole point of rust is safety, but honestly, the things I like most about using it are the quality of life features like cargo. I love the idea of bringing that to C!

Relevant to this thread: I've spent the last week or so hand porting SeL4 from C to Rust, mostly so I can learn how it works (and learn OS development more generally). One of the biggest pain points I've had trying to use SeL4 is understanding the insanely complex way it uses cmake to compile the kernel and userland software. With Cargo, I can just run `cargo build` on my rust kernel project and it just works[1]. I don't even have a build.rs.

Anyway, I'd love it if we had a tool that made sel4 so easy to build. I doubt it'll be that simple, but its a lovely goal.

For me, it’s always having website productivity blockers on all my browsers across all my various devices (and for the most part, not installing news apps on any devices either). Haven’t simplified my digital life, but at least it’s very restricted. Yeah, if even one device doesn’t have one installed, feel like am vulnerable to having hours sucked away.

And actually, still browse the web and watch YouTube, but just on my non-work days.

eternityforest2• 7 months ago

I did a similar thing a few years back, but rather than simplifying, I focused on getting rid of hacky DIY things that needed maintenance.

I got rid of almost all the customized software in my life, and the few projects I decided to keep, I aggressively modernized, getting rid of thousands of lines of original code and adding many times more tests than I'd ever had before.

It very significantly improved my life and career to not have a second part time job maintaining a note taking app.

Creating an we autobattler game https://lfarroco.itch.io/mana-battle It is being a good experience to learn how to work with shaders, and how well Electron apps run

mchaver2• 7 months ago

I am working on two things.

The first is a customizable digital math workbook. Currently the demo covers fourth grade math. There is a practice mode where you can select the skills you to want practice. There is also a customizable dashboard where you can setup your own widgets to practice math skills in different ways. I am working on some pre-made dashboards to help users get started. The next plan is to cover fifth grade math skills. My plan is to cover first grade math up to Calculus and High School Physics. I envision it as a companion tool for Khan Academy/Math Class/Math Books. Check out the demo. No signup required. Progress is only stored locally.

https://demo.numerikos.com/

The second thing I am working on is an application to practice Cangjie. It's a Chinese input method that has been around for a long time. It is based on a visual decomposition of characters. Each character is represented by one to five codes and the majority are unique. My application teaches Cangjie like keyboarding (QWERTY) is taught to young students. You learn the location of the keys, then some basic words, then start typing sentences. I also have a free demo for it as well.

https://demo.cangjieworkbook.com

Feedback on either project would be appreciated.

Completely free, no ads, no in-app purchases and no accounts / network required offline voice transcription.

I have also built the macOS/Windows/Linux versions which I'll also make free to download and available on my site soon (https://blazingbanana.com/).

iOS version is built and works (extremely well), just waiting for the Apple Developer signup process to complete.

Big shout out to https://github.com/mybigday/whisper.rn and https://huggingface.co/ggerganov/whisper.cpp/tree/main for making this even possible.

Any suggestions are welcome.

seinecle2• 7 months ago

Couldn't find it on the Play store by searching for the name and the developer's name: if it is not just me then your app is very hard to discover.

So I am installing it through the link you provided, which directed me to a "install success" page saying "your purchase is successful" even if your app is free. Another obstacle to adoption :-)

Last, I was not informed on the page of the app' size. Seeing what it does and the time it takes to download I am afraid it could be huge? Third obstacle :-)

hurflmurfl• 7 months ago

For me, searching for "whistle" on play store, I get the app as the third result (ignoring sponsored crap). Searching for "blazingbanana" gets me the app as the first result".

App info shows 218MB size, which I suppose is about what I'd expect for a model+app code :shrug:

properbrew21• 7 months ago

Thank you for the feedback, I really do appreciate you taking the time to check it out and write out the comment! I'll look at adding a note about total app size in the description, it won't hurt.

As for discoverability / the "your purchase is successful" message, I'm not sure what else I can do, I've set it to free, no ads etc in Google Play. Maybe I need to hit a few more keywords for transcription so it surfaces it more.

firefoxd• 7 months ago

Pretty cool. I've downloaded and lightly tested. Works great.

I love the "free forever, no ads part..." But it obscures what the app is for. Maybe start with the "Speech to text transcription" to make it clearer.

Either way, that's just semantics. Great job

properbrew21• 7 months ago

Thank you, really appreciate the kind words. I'll take a look at giving the description a bit of a once over for the next release coming soon.

figmert3• 7 months ago

It'd be nice to keep the voice recording too, as I noticed at least one thing that it transcribed wrong.

This way one can listen to the recording again, and correct such issues.

properbrew21• 7 months ago

Great idea and an option I'm looking at implementing soon with the ability to reprocess with a different model if needed. Cheers for taking a look.

abdullahkhalids10• 7 months ago

Would you consider adding it F-Droid?

properbrew21• 7 months ago

Yes absolutely! I'm a GrapheneOS user myself so understand not wanting to have to go through the play store if you can help it.

I believe you have to make the source code public (please correct me if I'm wrong). I'm more than happy to do so, I've used a whole bunch of open source stuff to build the app so it only seems fair, I just need to make it a bit less messy and something I don't mind being public.

mysfi7• 7 months ago

I really liked wisprflow on my mac but my daily driver is Manjaro KDE. I have stitched together a bash script that copies the transcription (right now I am using the Parakeet TDT 0.6B) to my clipboard. I would give this a try on linux when it becomes available.

properbrew21• 7 months ago

Just checked out whisprflow, I must say that looks really nice, kudos to those devs. Shame there isn't a Linux / Android version.

I have added the auto-copy to clipboard functionality that will come with the next Android release and be included in all others. Adding a hotkey / quickbar button is on the roadmap for the desktop versions.

If you want to give the Linux version a shot, you can download it from here - https://downloads.formait.app/whistle/linux/WhistleDesktop-l... - I've just stuck it in the same R2 bucket as another app, as I've not sorted the proper pipeline out yet.

pstroqaty• 7 months ago

Would you be open to sharing your script? I run whisper.cpp in Linux through some stitched together scripts (https://news.ycombinator.com/item?id=44949314), but would be very curious to try Parakeet. I don't believe I can run it through whisper.cpp?

bazzargh2• 7 months ago

On the subject of whisper being great... A few weeks ago a co-worker commented about the difficulty he'd had editing a work demo, I pointed at various jump-cutting tools that had automated what he did in the past (editing out silences). But I'd also wanted to play with whisper for a while...

So a couple of hours later I'd written a script that does transcription based editing: on the first pass it grabs a timestamped transcript and a plain text transcript for editing; you edit the words into any order you like and a second pass reassembles the video (it's just a couple of hundred lines of python wrapping whisper and ffmpeg). It also speeds up 4x any silences detected that sit within retained sequences in the video.

Matching up transcripts turns out to be not that hard; I normalise the text, split it, and then compare to the sequence of normalised words from the timestamped transcript. I find the longest common sequence, keep that, then recurse on the before/after sections (there's a little more detail, but not much). I also sent the transcription to ffmpeg to burn in as captions, because sometimes it makes the audio choppy and the captions make it easier to follow.

I know, tools have been doing this for years now. I just didn't have one to hand, and now I do, and I couldn't have done this without whisper.

properbrew21• 7 months ago

That is absolutely awesome and I love hearing about the tools that people build themselves!

Honestly, the capabilities of whisper is insane, the fact that it's free and open source is really a gift. Some of the things it can do feels almost sci-fi.

If you ever decide to release it publicly please let me know, sounds like a very useful tool.

cipherops3• 7 months ago

I spent a few hours editing a video in Davicni resolve to do this by hand. Then i found out this is a built in feature.

wosc• 7 months ago

That's very cool, I've been looking for a fully offline transcription app for quite a while. Thanks for building this! And thanks so much for providing an "import audio file" function, not just "record from mic" -- transcribing voice notes from various messenger apps is my main use case here.

Do you have an idea about supporting languages other than English?

properbrew21• 7 months ago

Thank you, glad you like it!

The average model and upwards should support all languages from the whisper models by default.

There was a bug causing the "translate to english" to be always enabled. This should work correctly and translate to your native language.

Will be in the next update (in a day or two).

figmert3• 7 months ago

I just tried running this on a 30 minute meeting with some 10 people in. It got to the end, then just bailed without transcribing. I also did not get any errors or anything.

properbrew21• 7 months ago

Really sorry about that, longer running audio (~10m+) is something I'm working on along with handling multiple speakers.

I've been focused on getting functional parity across all OS's since the Android release. This is very close to being done and I just need to reach the milestone of it being available on all platforms before I move forward.

Hopefully you will take another look when the next update is out.

ericmcer4• 7 months ago

Whoa cool, so all the transcription is done locally? Have you done any perf monitoring around that on iOS?

I have been using the iOS built in speechTranscriber and it is... not great, was gonna use a whisper API but running it on device would be amazing if it isn't too heavy.

properbrew21• 7 months ago

Hey, just spotted your comment.

Yes, everything is done locally, stick your phone in airplane mode if you want to be sure!

I'm not an Apple fan, but I have to say I've been testing it on an iPhone 15 and my god, the performance is insanely good, I was seriously blown away. I haven't dug into how much it impacts battery, but the transcription literally takes seconds for a minute of audio so it's not holding up your device.

The iOS version is built, ready to go, there's just some bug with my Apple account and it won't let me pay the £80 fee to signup (support ticket raised and waiting). As soon as that's sorted it'll be out on App Store for free as well.

Very surprised to hear the built in transcription is not great, anything specifically bad about it? The hardware is there.

You can download the desktop version from here (https://blazingbanana.com/apps/whistle/) if you want, still very much a WIP.

A tool for K8S operators that replaces brittle imperative reconciliation code with type-safe state machines generated from declarative YAML definitions. It also bundles error handling / logging / metrics / traces for state transitions.

Not sure if I'm missing a better tool but trying to keep a good working mental model of this has been a nightmare for the operators I've maintained.

JasonSage• 7 months ago

I'm building a yet another AI chat app.

My initial goal is to make a functional SillyTavern (AI roleplaying) replacement. SillyTavern builds prompts from a few rigid buckets (character, scenario, lore, system prompt, author's note...), which makes complex setups hard to manage. Content gets duplicated, settings have to be toggled in multiple places, and it’s easy to accidentally carry or modify state across conversations. Over time, it becomes difficult to tell what context is actually in effect.

I’m building an alternative that treats context as small, reusable pieces that can be composed and organized flexibly, rather than locked into fixed categories. Characters, settings, and behaviors can be mixed, reused, or temporarily enabled without duplication or manual cleanup, and edits preserve clear history instead of rewriting the past. The goal is to make managing complex context deliberate and controlled instead of fragile.

Although I’m trying to get the functionality required for roleplaying done first, the app is generic enough for other AI workflows where fine-grained, explicit context control is an improvement over existing chat interfaces. Think: start a new conversation with an assistant and start checking off rules, documents, and instructions to apply to the chat. Regenerate responses with clarifications or additional one-time context layers.

It's a work in progress, but it's at a stage where if you ask nicely I'll let you know where to download it.

There are a lot of apps that can be built on ATProto, the PDS, etc. If you are exploring the same space I'd especially like to hear from you. I'm easy to find, which is the most useful thing about being named Zigurd.

I'm building an application that can communicate with my Plex server, and also communicate with APIs like MusicBrainz and Spotify. From there I want to be able to track my Plex music rating history, and export playlists on Plex to Spotify for easier sharing with others.

There don't seem to be many automated tools out there that fit my need for this, so building out my own solution I have complete control over makes sense. It's a lot of fun to build this out exactly as I want to, rather than trying to configure a bunch of tools that I'm not familiar with and that don't meet my needs exactly.

The tooling I'm building up around this should hopefully make it easier for myself to get my playlists and track ratings off of Plex if I ever decide to abandon it for music listening.

I'm experimenting to see if frontier LLMs can do practical CAD modeling. I'm starting with a single task: designing a wall mount for my bike pump in OpenSCAD or CadQuery (two code-based CAD systems).

None of the frontier LLMs (Gemini, ChatGPT, Claude) produce usable designs when just prompted with some photos of the pump and a written description of the mount. I'm now building a simulator in Mujoco that the LLMs can use to test and iterate on their designs to see if they can do better in this setting.

I'm hoping to make an interesting blog post of it and maybe end up with a usable wall mount design.

claude models are sufficiently competent at directly making accurate MJCF files as long as you go part by part. directly trying to port from CAD may cause issues when trying to "close the loop" so to speak because of the kinematic tree approach.

Building https://floxtop.com, a native Mac app that organizes your files.

It looks inside each file to see what it’s about, then moves it to the right folder for you.

Everything happens on your Mac, so nothing leaves your computer. No clouds, no servers.

It works in 50 languages (including English, German, French, Spanish, Swedish) and with images (OCR and object recognition), PDFs, Microsoft Office, ePubs, text, Markdown, and many other file types.

If you have messy folders anywhere on your Mac, Floxtop can help.

This looks very interesting and I appreciate the pricing model and lack of cloud. It wasn’t clear from the site, but is there a check all moves prior to execution function? Undo?

bobnarizes2• 7 months ago

There is no automatic execution — nothing is moved without your confirmation.

Floxtop suggests the top 5 destination folders where a file could best belong. You stay fully in control: you can choose one of the suggestions, move files individually or in bulk (Move All), or select a completely custom folder location at any time.

If you change your mind, you can Undo per file or use Undo All to revert the entire operation.

I'd love to learn how you grew your audience so fast! I built https://dailybaffle.com but haven't reached your numbers yet.

paulhebert23• 7 months ago

Daily Baffle looks nice!

I’m not totally sure! Marketing is not my strong suit.

I think my biggest advantages are:

- It’s sticky. A good percentage of players keep playing once they start

- Organic sharing. Lots of people have told me they shared it with friends and family. (I also built a “share” feature)

The pattern so far has been:

- I share it or someone else shares it somewhere.

- There’s a big spike of people trying it out.

- I get some new players.

- The player count stays roughly steady until it gets shared somewhere else that gains traction.

It was featured by Thinky Games. Sharing here got people interested. Someone shared it on Metafilter and that got a lot of views. Other folks have shared it on other sites that have led to smaller bumps.

But I’m still experimenting.

s3graham• 7 months ago

I started playing a couple weeks ago (and got my Mum and one of her friends playing too).

I enjoy it, but I find the clues seem a bit too easy, and honestly I'm normally terrible at crosswords. Take that for what you will, totally understandable if you're aiming at "cozy/relaxing".

I appreciate the polish of the UI compared to a lot of the other janky word games out there anyway.

paulhebert23• 7 months ago

Hey, thanks for playing and sharing!

And thanks for the feedback! Balancing the puzzles is really tricky so it’s good to know when folks think it’s too easy or too hard.

It’s interesting to see the range of player skill (and how much they do or don’t enjoy challenge.) On a recent puzzle one player left feedback that it was too easy and another left feedback that it was too hard.

My aim is for puzzles to be challenging but not frustrating. The hard part is frustrating means different things to different people. From my stats I can see some players complete a puzzle in 2 minutes that takes another player 20.

For the daily puzzle I do lean towards making it a little easier but I want to explore a few ideas for making trickier puzzles in the future.

- Releasing additional “bonus” puzzles this are harder or more complex - Letting people build and share their own puzzles at whatever difficulty they choose - Adding settings to allow players to toggle things like hiding the theme at first.

That said, I’m still trying to figure out the overall balance for the daily puzzles! It’s good to know you think they’re a little on the easy side. I should try to gather more feedback and maybe tweak that!

8organicbits2• 7 months ago

I've been playing by just looking at the title of the puzzle and ignoring the clues. I can solve most of the puzzles that way, and it increases the challenge.

Some feedback: 1) it would be great if the incomplete clues could move to the top. this would avoid having to scroll down towards the end of the puzzle. 2) better collission behavior; it would be nice if we could drag a chunk of words and it would just "move the other words" out of the way. Sometimes we have to spend time to make a path to move chunks of words around.

Thanks for building this!

Hey, thanks for playing!

1) This is an interesting idea! I’ll play with that when I have time.

2) I am experimenting with this but have gotten mixed feedback from players. Some people don’t like it. I’m curious what you think! If I don’t do this I’ll explore other options: https://sunny.garden/@paulhebert/115698266272946749

I'm learning Java and hoping to finish a course and a big project I've been working on for a while.

sureglymop• 7 months ago

As we pile more and more abstractions on top with AI, I have been on a really fulfilling quest fueled by curiosity to go more low level.

I've been doing a lot of assembly, C, WASM and plan to top it off with a look at GPU instructions and PTX. I haven't learned as much as in the last two months in years, it's been great. And surprisingly everything has turned out to be much simpler and easier to implement than expected once demystified.

Now to be fair, AI has sometimes given me pointers when I didn't fully understand something. Using Gemini 3 for free has been nice in that regard. However I consciously try to only implement code myself and to actually make sure I learned something that sticks.

I’m working on a video game, purely for fun.

Here is a work in progress build:

https://muffinman-io.itch.io/space-deck-x

It is a combination of a shoot-em-up and deck building. You fly and shoot until you get to the boss, when you get your deck out to fight them.

That genre combination is definitely too ambitious, but I think it is fun to play and I’m enjoying making it.

I have a bunch of ideas how to combine the two parts better. But over the years, I’ve learned to control scope creep and actually ship pet projects.

Right now I’m in a middle of changing how enemy waves are spawned. After that I want to make a short tutorial and add two more bosses as well as more enemies.

If you end up playing it, please share your feedback I’ll be glad to hear it.

The game is made using Kaplay, a game dec library which brings me joy to use. I can best describe it as my friend described Pico-8: “easy things are easy”. But compared to Pico-8, Kaplay doesn’t have virtual console limitations and comes with a big library of components. Try it out, the community is small, but the library itself is really fun and easy to use.

EDIT: For context, this is about two weeks of work, in the evenings when my kid is asleep.

https://github.com/connet-dev/connet

Just finished a major (v0.10) revamp of the API (you can use connet as part of an application, not through the CLI) which also fixed a few issues I've been seeing before.

Now, I'm gearing to update the relay protocols - currently relays are closed off by the control server (e.g. you ask it to provision you a relay resource) which requires the relay to communicate with the control server itself. In the new version, the relays will be operating on their own (there might be a shared secret with the control server, in case you want a closed off relay) and peers will reserve directly with the desired relays. Maybe in future, the relays might form clusters on their own to take advantage of better relay-to-relay network and peers will reserve only at the relay closest to them.

Another stream of work, is giving peers identities. Right now the server will give them an internal identity to better support reconnects, but these are not stable (e.g. they don't survive client restarts). In future, the peer will advertise their identity and then other peers may choose what peers to allow comms with and what to ignore, pushing more decisions into peers themself.

Yet another change I'm thinking about is exposing raw endpoints to enable users of the system to implements other protocols - I'm not quite sure if this is really needed (the destination/source, e.g. server/client) covers a lot of ground by itself, but it would be great if these are not the only options.

Many options how to continue, but if I'm out of ideas, there is always a Rust rewrite to throw in /s

Ingon2• 7 months ago

Actually, I realized that I've used `/s` incorrectly. I've been thinking about rewriting the clients in Rust, mostly to allow simpler embedding in other languages - java and swift for example (I think it would be great if connet was available on mobile - for android you can Termux to compile/run it, but it is a pain). This will make it harder to embed in golang tho.

Another option is to try to rewrite clients in each of the language, but most fare poorly on QUIC support - in Java for example, I'm not aware of one that is advertised as production ready (looking at kwik with their fork of TLS).

A tool to build labeled object detection training datasets from large-scale satellite/aerial imagery collections: https://github.com/noahgolmant/label-tiles

Web maps usually join together lots of small images called tiles (this is why you see square patches as google earth/map loads). They do this by querying a "tile server" API. It turns out this standard can also be leveraged to label and fine-tune models on map imagery. In my day job we built infra to efficiently serve imagery through tile servers for map visualization. So I wanted to test out ML applications of that infra.

I'm still tweaking my tool for creating accessible Tailwind-style color palettes for web/UI design that pass WCAG 2 contrast requirements:

https://www.inclusivecolors.com/

There's 100s of color palette generation tools, where most only let you customize a single color then try to autogenerate tints/shades without much thought about accessibility or tints/shades customization. The main features of this tool are:

- Emphasis on accessibility. A live UI mockup using your palette warns you if your tints/shades are lacking contrast when used in practice for headings, paragraphs, borders, and buttons, and teaches you the WCAG rules. Fixing contrast issues and exploring accessible color options is also made much easier using an HSLuv color picker, where only the lightness slider alters the contrast checks, and not the hue/saturation sliders (most tools use HSL, where hue/saturation changes counterintuitively alter contrast checks which makes accessibility really tough!).

- You can tweak the hue/saturation/lightness of every tint/shade. This is useful because autogenerated colors are never quite right, and customization is really important for branding work when you have to include specific tints/shades. The curve-based hue/saturation/lightness editing UI also makes this a really quick process.

- Instead of just a handful of colors, this tool lets you create a full palette. For example, if your primary color is blue, you always end up needing other colors like green for success, red for danger, and gray for text, then 11 tints/shades for all of these, so you want a tool that lets you tweak, check, compare and manage them all at once.

It's mostly a demo on mobile so check it on desktop. I'm still working on making it easier to use as it probably requires some design background to understand, but really open to feedback!

kokada• 7 months ago

I am working (mostly vibecoded) a Git history explorer in Go+modernc.org/Tk9.0: https://github.com/thiagokokada/gitk-go. It is heavily inspired in gitk, this is why the name and usage of Tk for the interface.

The reason for it was because after testing multiple Git history explorers, I still think nothing beats the gitk. Sublime Merge is probably the only alternative that I would seriously consider but I don't really like the UI and the fact that it is proprietary (I am not against proprietary software but I prefer an opensource solution when available). Other alternatives have some bugs or the interface few too slow. gitk itself is mostly fine, but sadly it tries to load the whole repository in memory and this is causing issues every time I try to navigate through nixpkgs (I can see the memory consumption going through the roof while the UI slow down to a crawl).

gitk-go loads a batch of commits (1000 by default) and once you get at the end of the list it loads more. I also add a few features that I miss from gitk, for example if you do any change in the repository (change branches, add files to stash, etc) it will automatically reflect in the UI.

Again, the code is mostly vibecoded since this is the first time I decided to try this from scratch. The code works well for my use cases and it is enough to replace gitk for me, but I can't guarantee there is no bugs and the amount of tests are small. But still, it was fun to see something that I wanted to create for a while (I had this idea for a long time since the issues with gitk that I was having) finally taking form. Probably the program is not useful for anyone but me, but if anything this is a feature, not a bug.

Still working on Librario, a simple book metadata aggregation API written in Go. It fetches information about books from multiple sources, merges everything intelligently, and then saves it all to a PostgreSQL database for future lookups.

You can think of it as a data source, or a knowledgeable companion that can provide comprehensive book information for online booksellers, libraries, book-related startups, bookworms, and more.

I got a pre-alpha build running for those that want to test it out and the code is out on SourceHut[1].

Been really tough to find time to work on it because I have a baby that only sleeps in my lap, but I’m making progress very slowly.

I recently hired someone to rewrite the entire database layer, as that was written with the help of an LLM for the prototype, which should improve things too.

I'm working on a hardware/software utility to play Switch/Switch 2 games remotely with my brothers. I found a way to emulate a Switch Pro Controller using a Raspberry Pi Pico based on several different sources (look in the README for more info). I used that to write a firmware for the Pico (with the help of GPT Codex 5.1).

Then I wrote a Python program that connects whatever controller my brothers want to use (as long as it's supported by SDL2.0) and forwards that data from their computer, through Parsec, through a USB-UART adapter, to the Pico, then to the Switch. I then have a low latency capture card (Magewell Pro Dual HDMI I got off of ebay for $100) forwarding the video and audio from the Switch to my PC which I share to my brothers via Parsec. The audio was a bit tricky to get right, and ended up having to use a Virtual audio cable and Voicemeeter potato (a software audio mixer) so that both myself and my brothers could hear the audio.

It works surprisingly well and the latency is pretty low. I even got rumble working! (but not motion controls. If anyone wants to attempt it, I will accept PRs). I haven't done any formal benchmarking for performance, but my brothers and I were able to play Smash Ultimate without too much bother about latency.

You could also use the accessory Python library I made to automate switch controller presses (look in the examples directory). Might be useful for TAS speedruns?

The project is here for anyone interested. It's a bit rough and needs some cleanup and maybe a video tutorial on remote setup. But here is the WIP:

I'm building a utility to help DJs find "play-out" versions of tracks they already like[1]. You can play with it here[2]. Streaming services are optimized for Radio Edits. But to actually mix a track, I usually need the Extended Mix, Club Edit, or a specific Remix. Manually searching for the "DJ version" of every single track in a 50-song playlist is tedious administrative work that kills the joy of digging.

Remixify automates the search while leaving the selection to you. You paste a Spotify playlist URL, and it helps you or provides you a good starting point for digging. It groups the results by the original track so you can quickly preview and save the versions you want to a new playlist.

We don't try to recommend new music or use AI to guess your taste. It just finds the usable versions of the music you already selected.

I'm working on adding features to the snakemake aws batch executor plugin.

This is more experimental and not yet fully working. I wanted to try a few things. a) can we rely on existing job definitions (managed through IaC instead). b) can we implement a fire-and-forget model where the main snakemake process runs on Batch as well? c) Can we slim down the snakemake container by stripping off unnecessary features.

An PWA primarily for my wife and my daughter. They can order their hot chocolate and their coffee as if they were going to grab something at a fancy café downtown, but instead it's at home and I'm the barista. It is quite nice to have for when my wife comes back from work and want something specific, or when we are waiting for the visit of a few friend, they can order exactly the available beverages and everything is ready when they're here.

It was also a good playground for me to implement Web Push notifications (to never miss new orders).

It's a basic Nuxt 3 app with Appwrite as the backend with rough edges, but much enough for our household use !

If you want to spam my phone with notifications, please visit my café : https://mytinycafe.com/alix

MagicMoonlight2• 7 months ago

You should add food and prices too. Obviously you don’t need to implement an actual payment system because it’s for fun, but if it kept track of the money, your kid could charge you 0.50 per drink or something.

krlx10• 7 months ago

That's a nice idea ! Will definetly add it soon.

And for the food, one can already add anything, it's just a text field. A friend of mine only has alcoholic drinks and snacks on his menu page.

LOVE this. Are there any plans to open-source? I'd love to run my own instance.

Also some feedback: the ordering buttons are inexplicably in french despite everything else being in English. Choice of language or defaulting to English would be expected...

Also - multi-select and nullable options. So that I can create options like Taco / Steak / Pasta, and add side options that are relevant only when one of those is selected.

krlx10• 7 months ago

If there's a demand for it to become open-source, why not? But I'll have to improve code quality first. As the presence of french labels indicates it, i18n is not properly implemented for this project.

Very cool concept - thank you for sharing it! I think would be a great solution to the near-daily "what should we eat" problem.

If I could make a (not-important) suggestion, I think being able to re-arrange / categorize menu items would be useful. Something that lets you group together drinks apart from snacks as an example.

krlx10• 7 months ago

The "what should we eat" problem was a big source of tension in our household since the arrival of our first child. Too much time-consuming, too much planning effort. What changed our life (and I really mean it) is the app https://jow.com: it suggests you a list of meals for the week suited to your family and equipment, and it creates a shopping list for your preferred delivery provider. I only have good things to say about it and could go on for hours.

Web: The Good Parts, as seen by someone into dataviz

- scenes composed of SVG shapes, text, etc.

- web-worker rendering everything on the offscreen canvas;

- elements positioned via yoga-layout;

- optional JSX layer to define layouts, no support for React components inside the layout (yet);

- using Skia now, maybe Rive Renderer / Vello later? — I'd love to migrate to WebGPU eventually,

- first-class view transitions: no white screen, no jumps after the initial load, no things appearing/disappearing without a proper transition);

- fontkit to calculate everything re fonts and shape text — no more DOM-provided measurements;

- integration with Remotion to render videos.

Short-term goal is to reach MVP for slides/dataviz tool, and I'm getting close.

Just released the next version of Isograph https://isograph.dev/blog/2025/12/14/isograph-0.5.0/

TLDR the incremental compiler rewrite is finally bearing fruit. Namely, because we no longer have a batch compiler (i.e. we don't bail on the first error), we can

- provide LSP results (hover, goto def, etc) on non-broken parts of your isograph literals, even in the presence of errors

- surface those errors in VSCode, and

- fix those errors with auto-fixes!! (https://www.youtube.com/watch?v=6tNWbVOjpQw&t=314s) Which is to say, select a field that doesn't exist, and let the compiler create the isograph literal declaring it.

It's a great feeling to see this level of DevEx

Open source Nerf blaster simulator, for both spring and pneumatic blasters.

https://github.com/btrettel/blastersim

The core simulator part works, but I don't yet have a user interface or documentation. Probably just going to be text input files to start, maybe a GUI later. Recently, I'm mostly working on testing.

The simulator is object-oriented and basically allows one to build up a blaster from separate control volumes and connections between control volumes. This is useful as it allows the same core simulator framework to handle different blaster configurations and even variants of them. For example, someone asked me to make the spring piston able to pull a vacuum on its back side due to not having sufficient flow. That's easy here as I just need to add another control volume and the appropriate connection onto the basic springer configuration.

- a next-generation post-RSS newsreader. But news is so depressing these days. I think most of the world wants to ostrich and I don't blame them.

- a reboot of Svpply, my own shuttered startup. I'd love to just make (another) thing that's about excellent clothes and shoes and artisanal pocketknives, but the way the economy is going, this feels grotesque. I was lucky to make it the first time when luxury goods were attainable _and_ normal people could pay for necessities; that window has closed.

Building https://localhero.ai, automated on-brand i18n translations that run in your CI pipeline. Right now I'm working on better .po/gettext support, based on feedback from an early customer. With gettext you usually keeps source strings in the actual source code. So I'm building a workflow where non-technical people (PMs, designers) can edit translations in the web UI and then easily generate a PR with both code changes and translation file updates. Trying to make translations work smooth for both automated CI pipelines and PMs/designers who don't live in Git, when translations are checked into the repo. Also going through my network, talking to devs and localization folks to understand what could be improved in their orgs for translations.

I’ve been building a crypto market visualization and simulation tool because I kept running into the same problem: TradingView is great for charts, but it’s hard to answer simple “what-if” questions like would rotating into another coin actually have helped or did trimming and buying back improve outcomes, or just feel good in hindsight. So I started building tools that simulate these scenarios directly on historical data. For example: - flipping from coin A into coin B and back again over a chosen period - selling part of a position and buying back later after a drawdown

I’m still early and adding ideas as I go, but it’s already helped me questions I had.

Examples: - Coin flip simulation: https://www.blockviz.xyz/simulation/coin-flip - Sell & buy-back simulation: https://www.blockviz.xyz/simulation/sell-buy-back

It feels like somewhere in the last decade we've all lost control over our email inboxes. While it would certainly be possible to filter and sort it, I've been wondering if it makes sense to just start with a system that is designed to intake a bunch of streams of information. Then it could be pointed at the raw information e.g event calendars and news-letters as well as streams like Facebook groups/Instagram where I don't want to actually go to those apps.

Speaking at a meta-level, this seems like what we should really be using LLMs for right now: use-cases where user controls what is done on their behalf.

I'm going on 63, and could easily finish my career without AI, but where's the fun in that?

One amusing thing I've noticed is that every time the AI generates code with a hard coded hexadecimal constant, it's a hallucination. My son suggested feeding all of the chip datasheets into the AI and see if the constants improve.

It is going poorly so far, but each iteration gets better, so hopefully I have everything down before I end up with 100+ unsellable mugs in my kitchen.

Building an app that scans file systems prior to being migrated into M365. Looks for common governance issues and file and folder trees that won’t play nice in SharePoint. Not a migration tool as such, just something to scratch a consultancy itch. Python and Tkinter for now until I hit something that requires more complexity. Also a command line version that I’ll use more often. This probably could have been a PowerShell script but this is more fun.

This week I vibe coded an golem-forge (https://github.com/zby/golem-forge) - exploration of prompting as programming. Since then I found https://github.com/badlogic/pi-mono and https://github.com/johnlindquist/mdflow and I think I'll rather use these existing tools to explore my idea. But I think it might be still interesting project because it is entirely vibe-coded - I don't even know Typescript (I know some Javascript from before React - but none of the new stuff). I did not look into the Typescript code at all - only at what the LLM presented to me when editing it and the docs. At some point I discovered that when I tried to have a core logic and two UI packages the LLM put only types in the core package - so I had drive a hard refactoring - but it worked.

I haven't yet tried this very extensively - but another profound change in programming that this showed me is that it is now very easy to borrow parts of Open Source libraries. It used to be that you could only base your work on a library - borrowing parts of projects that were not designed to be shared (used as libraries) was prohibitive - but with llms it is entirely possible to say: "now please borrow the UI ideas from project X" and it does that. Maybe you need to add some planning.

The project is about 27kloc now.

On Thursday I learned about ulid[0] which I think really neatly solves the problem of text representation for UUID v7. However, I also like the idea of prefixed ids, although I haven't used them in anger.

Yesterday I built most of a Postgres extension, using the excellent pgrx[1] project, that build on ulid to add prefixes. With it you get something like this

    plid=# SELECT gen_plid('u');
             gen_plid
    ---------------------------
     u_06DHRQH6SJT7N2WEQK4910R
    (1 row)

The aim is for it to be the same size as a UUID in storage, but I haven't quite gotten there yet.

I haven't pushed it to GitHub yet, but it's fairly done at this point.

My biggest project is still Materia[0], a tool for deploying applications with Podman Quadlets. This month I presented it to the Podman User Group's community meeting, which was pretty exciting since I've never presented in a community setting like that before. Otherwise I've been trying to focus on bugfixes, minor feature additions, and working with user feedback so it's not just me fixing my own problems :) . The latter is really fun since I've already run into someone using it in a way that's very different than how I'd imagine it.

Not coding related, I've been on what I've been calling "The Grand Project" for a bit over a year now where I listen to every single album I own (around 855 albums/singles/eps/etc. As of this moment I'm at 828) at least once. It's been a real trip essentially going through my whole life musically and I'm hoping to write a blog post somewhere about it.

I'm currently working on something that lets you describe a hardware product in plain English and get actual manufacturable files out — PCB, enclosure, firmware, the lot.

Very early days still. Whilst I created a fork of toon for Kicad (called TOKN (https://www.mikeayles.com/#tokn)), with the intention of using a reduced token format to generate schematics using LLM's, I could get the models to follow the syntax correctly, but they didn't have the knowledge. So I was then going to create a whole RAG system, but got distracted by this current project.

There are people out there doing AI schematic generation, like flux.ai (which is incredible (and incredibly well funded)), but 90% of products, especially at proof of concept stage, are basically a microcontroller, some power, probably usb, and some IO, bluetooth/wifi if you're lucky. So we can use a library of pre-validated subcircuits and slots them together on a grid. Routing's deterministic, so if it compiles, it works. (sorry, deeppcb & Quilter!)

The enclosure side is more fun: once the PCB's done you've got real dimensions to work with (board size, mounting holes, where the connectors poke out), so I use an image model to generate some concept art, then feed that to an openscad generating model as visual inspiration alongside the hard constraints.

Basically trying to get a full hardware product pipeline done automatically.

I'm working on brand new type of collaborative whiteboard that allows anyone (or team) to drag-n-drop items from their devices onto the board.

The problem I'm solving: On a team, people and their files are scattered everywhere.

Solution: A canvas that attempts to open (and edit) as many file types as possible (images, xlsx, pdf, docx, cad). This means you can have people and files on the same page.

It's the only whiteboard that can natively render docx and pdf so far; these can also be edited directly on the board without having to use dedicated software.

It has a built-in Drive where you can store/backup files that syncs across your devices.

There's a few widgets such as Kanban, sticky notes, cards.

And of course, there's agentic LLM (Gemini 3 Pro) that can take actions such as viewing the board, reading documents on the board, and editing items on the board. For example, you can tell it to read a pdf, then write a spec sheet (in docx), or create tickets on a kanban.

I'm launching a private beta next month if anyone is interested in testing it out and giving feedback.

I'm currently making a number of "breadboard-able" analog computing modules.

I've always loved electronics since I was a kid (still trying to learn). As I explore and learn I've begun to make these small "breadboard helpers" [1]. (Just one on Resistor Transistor Logic (RTL) right now.)

An obsession over a project in a 1970's hobbyist electronics magazine sent me down the rabbit hole that is (was) analog computing. So I have been bread-boarding and prototyping small analog computer modules.

I'm in the PCB-layout stage for the modules and hope to have them ready early next year.

A few years ago, I made a model skinner for Tribes 2, a ~25 year old game that still has a loyal following: https://exogen.github.io/t2-model-skinner/ (if you check out the Gallery link there, you'll notice this app resulted in a whole new wave of skins, and even a Halloween skin contest)

To satisfy the urge of doing something else ambitious in the browser, I'm now doing the same thing for Tribes 2 maps: trying to make a web-based map viewer and editor: https://exogen.github.io/t2-mapper/ (editing/creation part still in progress)

I got this working for most maps pretty quickly. It translates the mission object tree from the Torque .mis files into a Three.js scene graph. Eventually though, I noticed that some mission definitions were more dynamic – Torque .mis files are really just TorqueScript .cs files with a different extension and some pragma/magic comments. So, to actually handle every map would require not just a mission file parser, but a whole TorqueScript runtime. Implementing THAT part seemed really tedious and, frankly, uninteresting to me. So I had Claude Code get a whole TorqueScript transpiler and runtime working. Now, when you load a mission, it actually runs all the same scripts that Tribes 2 runs to load the mission, all the way from server.cs and its `CreateServer()` function.

Currently, I'm continuing to get its rendering matching Tribes 2 as closely as possible, and setting things up so that live editing of missions will work.

I'm building a temperature controlled dough proofing enclosure based on ESP32, an IKEA Samla storage box and an inexpensive silicone rubber heater. It's delightfully impractical-- purely a first hardware/MCU learning project and a holiday gift for a relative who I think will appreciate it.

I'm impressed by how far I can get "vibe making". Most of my professional experience is in high-level software, but AI gets me unstuck quickly when I don't know something specific to ESP-IDF or the hardware. As of today I've got a circuit tested, firmware nearly complete, and a custom PCB en route from JLCPCB.

One limitation I’ve noticed: ChatGPT struggles with the details of part selection (e.g. choosing specific temp/humidity sensors or connectors). Adding datasheets to the context helps a lot, which makes me wonder why this isn’t something the model can do or at least ask for.

I'm working on WishKeeper https://wishkeeper.io.

It's a webapp that lets you create wish lists and share them with family and friends. The key feature is the claim system: when someone decides to buy you an item, they can claim it so others know it's taken, but you never see who claimed what or even that it was claimed at all. The surprise stays intact. You can also split big purchases. If someone wants a $400 stand mixer, multiple people can chip in allowing family tight on cash to feel like they're contributing without having family members feel like they have to put small items on their list just so everyone can contribute.

I kept it deliberately simple. No social features, no feeds, no ads. Just lists with items, links, prices, and notes. You create a list, share the link, and you're done. No group chat gymnastics required. It's free to use. I built this because I wanted it to exist, not because I had some grand monetization plan. You can sign up and create lists without a credit card.

Suggestions welcome!

Published my first AUR package this week. It's called bleep, a simple interval timer that beeps.

The idea came from cooking bolognese. I needed something to remind me when to stir. So I wrote a small Go tool that just beeps at whatever interval(s) you set.

Then I kept adding stuff. Verbose mode with a live countdown, pause/resume with signals, and a JSON output mode that works with Waybar. That last one is actually my favorite part. I get a little timer in my status bar that changes color when it's counting, paused, or beeping. Click to pause. Works great for pomodoro or just keeping track of things while working.

I switched from Mac to Arch and wanted to try the whole AUR thing. Used GoReleaser to automate the build and publish. Took some fiddling but it works now.

Working on a TUI tool which demonstrates the behaviour of X86 SIMD instructions. This is all done in Go assembly, and is probably most valuable for Go programmers.

The problem for me was trying to read and understand the implementation of a swiss map implementation. The SIMD instructions were challenging to understand and the documentation felt difficult to read. I thought that if I had an interactive tool where I could set the inputs to a SIMD instruction and then read the outputs, understanding the instructions would be much easier.

This turned out to be true.

Building this tool for all AVX/AVX2 instructions turned out to be a larger task than I had expected. Naively I just went off a Wikipedia page on AXV and assumed it had listed all the instructions (this was a bad assumption).

I am nearly there. Looking forward to completing this project so I can actually use it to do some fun stuff processing text and maybe even get back to that swiss map implementation.

I’m working on an open-source thing that lets you co-draw diagrams with an LLM inside draw.io/diagrams.net.

You can ask the model to rough out an AWS/GCP/Azure architecture, but the key part is the loop: you still have the normal editor, so you drag boxes, rename stuff, add your own bits, and then say things like “clean this up”, “split this service out”, “add a read replica here”. The AI edits the real draw.io XML, it’s not just generating a picture, so you and the model are basically sharing the same canvas.

It can also try to rebuild a diagram from a screenshot/PDF and then you keep iterating together in chat + manual edits.

Recently I added “bring your own API key” for a bunch of providers and support for uploading PDFs/text to turn existing docs into diagrams.

Repo (just crossed ~10.2k): https://github.com/DayuanJiang/next-ai-draw-io Demo: https://next-ai-drawio.jiang.jp/

Lite³: a binary format encoding JSON documents as a serialized B-tree, making it possible to construct iterators on them directly and query internal fields at indexed speeds. It is still a serialized document (possible to send over a network), though now you don't need to do any parsing, since the document itself is already indexed.

https://github.com/fastserial/lite3

Retr0id2• 7 months ago

Very interesting. How does it deal with "holes" left by deletions/edits, is there an equivalent of VACUUM?

eliasdejong2• 7 months ago

When overwriting fixed-sized values like integers or floats, the old value can simply be overwritten. Holes are only left if the overriding values do not fit in the old location (strings, byte arrays).

To clean up unused space, you start an iterator at the root of the document and recursively write to a new buffer. This will clean up all the unused space. This operation can be delayed by the application for as long as they wish, until the size trade-off outweighs the cost of rebuilding.

A database desktop client, built with Tauri & SvelteKit.

"But there are many already!" I hear the crowd exclaim.

I respond, "Yes, but..."

It's really something I want for myself. Lightweight, as fast as humanly possible, extensible via plugins (in fact the entire app is mostly plugins, with a small core to glue it together), and a tiny bit of LLM (call it AI if you wish) integration to ask questions about the database or generate/review queries.

Started working on an application to make it easy to see what parcels in NYC are upzoned with the City of Yes[1] changes that were passed last year.

I started off trying to make it a service to help people who are interested in ADU's get connected with architects/ contractors but spent a lot of time working on the interactive map to explore related ideas. The site is here buildbound.xyz and map here buildbound.xyz/map. Right now for example, it's very hard to tell if your site qualifies for the TOD upzoning portion of the City of Yes so maybe there is room to crunch those kind of numbers and provide it as a public service.

Trying to decide to keep going down the ADU route in NYC, even though the market is really early here, expand to NY State/ California where the ADU market is a bit further along or keep doubling down on making the best interactive zoning/ land use map in NYC and see if there is any product market fit to be found.

I resurrected some of my old code for computing hash collisions: https://github.com/DavidBuchanan314/birthday_party (it's actually more of a rewrite)

It can collide 96-bit truncated sha256 in under 24 hours on a 6700XT.

Next steps are a) figure out something interesting/useful to do with it (beyond surprising people), and b) modify it to support accepting contributions from untrusted clients (see "Future Ideas" in README). For a sufficiently interesting answer to a) I could create a "SETI@home"-like system.

A ~102-bit collision would cost $$ worth of rented GPU capacity, and 128-bit is optimistically possible with enough crowd-sourced compute (a ~5-figure dollar cost if you were renting).

Findecanor• 7 months ago

I'm looking at how to introduce unique, borrowed and GC'd reference types into the IR for my VM/runtime.

I'm inspired by the language Lobster's compiler that specialises functions to arguments of either reference type as a way of doing something analogous to using "escape analysis" to allow objects to be owned by the stack. I think that perhaps specialised functions could be re-merged, with compile-time checks replaced with very cheap runtime checks taking advantage of "upper byte ignore" bits in pointers.

The VM will also need to support not just managed source languages, but also languages where unique and borrowed references are statically checked and possibly stored in objects.

I'm working on a graph representation of complex data flows through a large organisation. The graph looks like crap, partially because hierarchical dagee graph layout algorithms apply a naive way of removing cycles that ruins the shape of the graph.

I've figured out a better way to remove cycles that preserves the shape of the graph in a way that works well for our purpose. Now I just need to figure out how to minimise edge crossings and line up nodes in such a way that it's more immediately obvious how the data flows between different systems.

It started out as a take-home assignment for a job I’m interviewing for (they asked for about 10% of what I ended up implementing but I wanted to do/show more :). It’s an aggregator for crypto exchange data.

The app reads the public data stream from exchanges, handles the nitty, gritty details of each exchange’s websocket connections, deals with its quirks, cleans up and normalizes the data into a uniform structure (currently only supporting spot trades) then exposes it downstream as an SSE stream.

Uses Go, Templ, and Mithril.js, and is open source

Working on a visual language learning app called Snapalabra!

The idea is simple: You look at an image and describe what you see in your target language. That's basically it!

My reason for building it was that even though I can understand a lot of spoken spanish, I really struggle to construct sentences on the fly when speaking. Doing a few minutes of active learning like this each day really helps remap my brain a little, and I quickly run into situations where I hit a wall and realize I actually don't understand something as well as i had thought.

The app also gives a little feedback on what i have written from an llm, and it also provides clues that I have mapped to each image.

At the moment I am using it mainly for intermediate Spanish and beginner Irish, and personally I find it really helpful for both. Basically learning vocan for Irish, and more serious sentence structure etc. in Spanish.

I know a lot of people absolutely hate the idea of mixing LLMs with language learning, and I can kind of see why, but I personally find it really helpful in certain cases. If you are already doing classes, and consuming content in your target language I think something like this will be really helpful for a 5 minute coffee-break type activity in the morning. Its not a language course and I have not intention for it to be one. Its just a supplementary little tool that helps with getting your brain thinking in a new language and it is free to use.

- Building a micro-learning platform that uses AI-powered role plays and conversational assessments to gauge learner understanding instead of eg. a multiple choice questionnaire.

- I’ve just started designs and initial setup for a personal productivity system heavily inspired by the Newton & HyperCard and built in Rust. Idea is to use LLMs to build GraphRAG-like connections between content & break out of the standard app+document model. My current thinking is having ‘frames’ of content (notes, sketches, events etc) that are acted on by capabilities and displayed in views (timeline, calendar, stack, knowledge graph etc).

- Also working on a static site generator and CMS webapp that creates sites that can be viewed on anything, from web browser to TUI. Like if Gemini or Gopher also rendered to html.

I'm working on Ward, a Chrome extension that detects browser scams/phishing using lightweight LLM models. Our target persona is elders, young children, and anyone who's not as tech savvy. When explaining it to people, I call it a "modern antivirus", because it can detect anything from malicious scripts on a page to grey-area misinformation on social media.

I'm bootstrapping and covering LLM costs for Ward's first couple hundred users (got about 50 users at the moment) to improve it. We have a local mode for added privacy and are dipping our feet to gauge biz. interest (client-side phishing protection is unparalleled).

I've recommended it to friends, colleagues and loved ones. I dogfood my own product, and it even surprises me every day how much more mindful it makes me of my browsing of harmful content. Would love to get feedback and testers from HN.

Advent of Code challenges

ChristopherDrum• 7 months ago

I shared this last month, and it seemed to resonate with people, so I'll share again and maybe new eyeballs will see it this time. I'm continuing to build a body of work on my retro productivity software blog, Stone Tools.

https://stonetools.ghost.io

Previous articles which resonated with HN were on Deluxe Paint and VisiCalc. The latest post, "HyperCard on the Macintosh," seems to be making the HN rounds currently. Bret Victor himself chimed in on the HyperCard article over on Mastodon, filling in some nice historical footnotes. https://posts.dynamic.land/@bret/115716576717006637

Unlike many (most?) other retrocomputing explorations, I specifically do not look at games nor do I tie myself to any particular machine, though I'm focused on the 1977 - 1995 period. I spend a minimum of two weeks with each productivity title, trying to learn it, building things with it, and generally trying to understand its approach to solving problems. I'd characterize my writing tone as casual, conversational, and decidedly light-hearted.

Each piece of software (so far, knock on wood) gets me thinking about some other aspect of related computing history, so I explore that as a tangent. With the Superbase article, I talked about "the paperless office." With the VisiCalc article I considered its impact on less obvious industries, notably hog farming.

I hope the passion and effort I put into the articles comes through. If you're interested in computing history beyond just the games I think you'll find something of interest on my blog. "This Week in Retro" did a segment about me and my various projects as well, if you're curious to get an overview of what I'm all about (link is queued up at the start of the segment) https://youtu.be/UHYscl1Ayqg?si=7JM1sZagjoqvPjk2&t=2137

Building postgres server as a library. Some early success, but initdb and in-process restarts are much harder than expected

mysfi7• 7 months ago

Do you mind elaborating more about the use case? Postgres itself is heavily engineered around OS process boundaries for both correctness and resiliency.

deivid2• 7 months ago

I'm not sure it'll be a serious project, but the main goal is to use it in CI or dev, where setting up postgres is kind of a pain.

I got it to work already by setting up the global context in single-user mode (like postgres --single) and exposing bindings for SPI operations.

Yesterday night I got extensions working, but as this project builds as a static archive, the extensions also have to be part of the build. Both plpgsql and pgvector worked fine.

The bigger challenge is dealing with global state -- comparing the pre-start and post-shutdown state of the process memory, about 200 globals change state. Been slowly making progress to get restarts working

Wanted to save up a few tokens when passing data to LLMs and did not like anything on the market, so I made minemizer.

Minemizer is a data formatter that produces csv-like output, but supports nested and sparse data, is human readable and super simple.

It produces even less tokens than csv for flat data, due to most tokenizers better tokenizing full words that contain a space before the word, and leads to less fragmentation.

There are many cool things I discovered while running tons of testing and benchmarking, but it's getting late here.

Code, benchmarks, tokenization examples and everything else can be found in the repo, but it is still very WIP: https://github.com/ashirviskas/minemizer

Or here: https://ashirviskas.github.io

EDIT: Ignore latency timings and token counts in "LLM Accuracy Summary" in benchmarks as different size datasets were used to generate accuacy numbers while I was running tons of experiments. For accurate compression numbers see compression benchmarks results. Or each benchmark one by one.

I will eventually fix all the benchmark numbers to be representative.

A Civil 3D plugin (Genabler) that will include all the network catalogs and collate the Civil 3D styles for civil engineers to use. There are some out-of-the-box catalogs and styles shipped with the default installation, but they are quite limited and fairly well hidden—which is not surprising, given that Civil 3D is a huge beast. As a result, they are not commonly used. When people think about Civil 3D, they often assume it requires BIM modelers (in a sense, just glorified drafters) to create all the necessary catalogs and styles, and to assist with their use.

My Civil 3D plugin will:

1. Make standard, market-compliant catalogs and polished styles available to engineers at large. Think of it as the WordPress theme provider equivalent.

2. Make the entire process easy and painless through the plugin, with prominent buttons for quick access.

If the plugin is done well, there will be less need for BIM modelers, since for a fee, engineers could simply purchase catalogs and styles that are so easy to use they require no technical training.

As a side benefit, I also get to explore how LLMs can help me write code. It has been a while since I last updated my AI usage policy [0], and I look forward to revisiting it.

*Supex* - Agentic coding for SketchUp.

Working on a house renovation project in SketchUp, I wanted the same workflow I use with Claude Code: describe what I need in natural language, let AI write and execute the code, iterate quickly.

So I built a bridge. Python MCP driver talks to a Ruby extension inside SketchUp via JSON-RPC. Claude Code can now write Ruby scripts, execute them directly in SketchUp, take screenshots to verify results, and introspect the model - all without leaving the conversation.

Still very early (macOS only, requires SketchUp 2026), but it's already useful for repetitive tasks and parametric designs. "Create a spiral staircase with 15 steps at 18cm rise" is more fun than drawing it manually.

Your VMs are a bit pricier than some other larger services located in other parts of the world - which I understand. I hope you are able to scale to the point where you can lower these prices.

Are there any legal or other reasons I, a resident of Canada, should host my services in Canada rather than in Europe or US?

pkd3• 7 months ago

Thanks for taking a look! You are correct that we are not competing with the cheapest offerings available there are two key things that are different with us compared to some low-cost providers (like Hetzner):

1. Our prices are in CAD and we bill in CAD, not USD. For Canadian residents this saves on exchange-rate uncertainty. Although sometimes people miss the C$ part and compare it with USD pricing - looking to make this more visible.

2. We don't have limits on transfers, but bandwidth. Hetzner, for example gives you limited amount of transfer for your money. They probably want to stop abuse but it limits legitimate users as well, even though it costs them no more money to transfer the extra bits.

(I use and like Hetzner, not trying to throw shade on them, just using as an example).

Are there any legal or other reasons I, a resident of Canada, should host my services in Canada rather than in Europe or US?

Certain industries in Canada are regulated and need to be hosted locally. However, we are not trying to appeal to that. Instead, we want to focus on physically-local hosting because we believe that the world needs more small-scale ISPs, not centralization into big hyper-scalers. The collateral benefits are incidental: like being able to sue in Canada, and being subject to Canadian digital privacy laws (e.g. the DPA).

This is still in development (todo are privilege dropping, in place config reloads, log burst suppression, multiple listen sockets (which paired with the Linux kernel gives free load balancing capabilities), and detailed TLS configurability), but it already matches both nginx and HAProxy’s speed (entirely bottlenecked by OpenSSL crypto by this point) at a tiny fraction of the attack surface and memory footprint (10-15kb per worker process last time I checked).

I am not really working on anything big right now, mostly just improving what I wrote, in particular documentation-wise.

However had, on my todo list ... a few things that are important to me are there.

One is to create some kind of pseudo-language that can model biological cells, from A to Z. I am having something similar to erlang in mind (to some extent). Now, this is nothing new - modeling is quite old, bioinformatics is old, but I have a few ideas that are somewhat novel IMO (e. g. really following erlang here, just adapted to biological systems).

Then I have a few smaller ideas. One is to finish a webframework where everything is really an object at all times. Meaning, I can work with objects when describing a webpage, from A to Z. HTML tags are objects too. I don't typically use them directly, though, but more in a meta-layout, e. g. I want to describe a webpage, but on a higher level, and also push that down into a .pdf file then seamlessly. My goal here is to be able to work with objects everywhere, not just for a single webpage but for all local and remote webpages, a bit similar to Alan Kay's old ideas.

I have a couple more ideas (one is the widgets project where I want to describe a GUI only once and then have it work in as many variants and languages as possible), but realistically I also focus on the smaller things to do as they are much easier to solve. Right now it is more important to me to finish as much as possible before the end of the year, so prioritising on smaller things makes more sense.

I wrote a Telegram bot for video/image translation, and also Firefox/Chrome addons to help translate web content with smart content extraction and non-breaking layouts.

Check it out at: https://addons.subly.xyz & https://subly.xyz

The Firefox addon/Chrome extension is free, but you need your own OpenRouter/Gemini API key. The cost of web translation is really low, you can translate an article for ~$0.01 with really good quality. (You can try at https://addons.mozilla.org/en-US/firefox/addon/subly-xyz/)

I built it because I use Firefox the most and it seemed like no translate addon was good or simple enough. Chrome translate kinda works, but the quality is so low; it usually doesn't understand the article context.

I'm working on a tool in golang to handle requesting access to private and sensitive databases in Postgres. The goal is to help orgs reduce handing out long-lived postgres creds with broad permissions.

The flow is you declare the databases and tables you want to access and the specific permissions you want, an operator reviews it, if accepted it generates a temporary postgres user with those permissions you need. Also, all the connections to the database are proxied through the app, so the domain name and port are random and short-lived, so you don't expose internal database hosts. As an extra, all SQL statements during the user sessions are logged if you want to see that.

It's available at https://github.com/yungwarlock/pam_postgres

My primary goal of this is to drill myself as a product engineer working on a technical product.

st3fan• 7 months ago

I just put something similar together but then on top of Openbao which generates temporary credentials/roles for Postgres.

2. Sometimes a good post is ignored due to a bad title, sometimes I still have no idea what the post's theme even after I read a few paragraphs.

3. I want to filter out some posts I'm not interested in, but I realized I need read some other posts it's not a simple yes/no problem, so I gave every post a interesting score based on my own preference

I've spent a considerable amount of my free time over the last few years working on an open-source game engine for making Zelda-like games (link in profile). It's been around for a few decades, and I played it when I was a kid - and now I'm contributing heavily to it. To give a since of scale, there's ~1000 custom fangames made in this: so pretty niche, but if your thing is Zelda it's got some real gems.

Most of my time has been spent practically rewriting the engine from just single-screen play areas (like Zelda 1) to be free-scrolling (like Zelda 3). I've also put lots of work into supporting all platforms (was just Windows; now it's also Mac/Linux/Web). And I've delved into tons of interesting programming projects while working on this: a deterministic record + replay testing system; a garbage collector for our custom scripting language; JIT compilers for x64 + WASM; a VS Code language server; the list goes on...

Anyhow, this month I'm trying to polish it up as much as I can so we can officially release the next major version.

Fringe physics: Trying to understand WTF the A field is in electrodynamics, and how I can measure it for a price I can afford. Specifically, I want to communicate through a wall of rock or sea water at VHF frequencies, with high bandwidth. I just upgraded my subscription with ChatGPT to try to grok all of the physics involved. It decided that since this could be used to covertly exfiltrate data, it wasn't something that could be discussed. ;(

Recently a friend acquired a Collins KW-1 transmitter, serial number 1. I helped him get it working again after a long period of disuse by it's previous owner. You wouldn't believe how often it turns out that wires and bolts don't actually conduct electricity.

simpaticoder• 7 months ago

Maybe I can help with one or two conceptual things. In classic E&M a field describes the potential (or force, if you prefer) a test charge would experience at that point. Note that the general case is impossible to visualize, as you're associating 6 numbers (3 for E 3 for B) with every point in space, so we normally think of simple setups and slice them up. Accelerated charges make waves in the field which are WAY more complex than people think. The way you model matter is dependent on the frequency of light. For visible light you normally think of it (especially metal) as a crystalline lattice of some characteristic length, electrons that can jump discrete energy levels, with molecules forming some sort of dipole that has more degrees-of-freedom (wobbling, twisting). I don't know about VHF, but the wavelengths are huge, like kms, and therefore way too low energy to cause electron shell jumps, so you'll probably model matter according to some very general characteristic like permittivity and conductivity. For seawater (which is a good conductor) subs use ELF, which is 100s of kms in air and can only communicate at bits/s. It's a fascinating topic, and very niche. Good luck!

Electrodynamics is taught to literally millions of people in Physics or engineering degrees across the world. It is the furtherest from fringe as it could be.

But here's a TL;DR

- Files are end to end encrypted with a master key generated by you on your device during onboarding

- How do your family access the documents when only you have the key and it's E2EE? The idea is the key is splitted via Shamir Secret Sharing when you add a trusted contact, once the doomsday is triggered and they recieve the notification, only then they can use their "shares" to reconstruct the master key and open your vault and access the documents

Porting/reimplementing a Tcl interpreter from C to Zig, based on the design of Jimtcl. This is one of those sub-projects that started due to another project (folk.computer in this case). The biggest difference is thread-safe value sharing, and (soon to be) lexical variable capture.

But why? Right now folk.computer has about a 20% overhead of serializing and deserializing values as they get sent between threads, and it's also meant we can't sent large amounts of data around. I previously attempted to make the Jimtcl interpreter thread-safe, but it ended up being slower than the status quo. So, I started hacking on a new interpreter.

Commands evaluate, basic object operations are in place, but there's still a ton of work to do in order to implement core commands. It may even be good enough to swap in some day!

I'm working on a beginner-friendly online programming language for teenagers who want to learn to code. I think there is not a clear enough winner for what teenagers should do after they learn Scratch so I am trying to make it.

leecommamichael5• 7 months ago

I saw this shared recently. The site presents nicely, and I agree there's a gap there. As a university professor, the story of my students' learning has pretty much been; Scratch, some Python, and then they pick up whatever early-college curriculum is. There's a strong preference for scripting languages like Python and JavaScript.

When you say "what teenagers should do after learning Scratch," what do you mean exactly? Should do to what end? How would Easel present as "the clear thing" they should do? I suppose Scratch wasn't really chosen by these young people; it is obviously simple, and has the prestige of MIT. Schools followed suit.

You're in a different situation, where you have to meet this market in the open. When I visit your site, I am met with code. It's not apparently simple, and a beginner wouldn't be able to distinguish it from any other games programming framework. I think it's actually scarier-seeming to a beginner than something like Godot's scene editor, where you can just drag images from your disk into a prototype-view of your game-scene.

I hope my plainness in stating this isn't taken as an insult. You've got so much work there, and the site is impressive. I also care about this topic, age-range and the learning process, so I'm trying to be helpful with my perspective.

BSTRhino2• 7 months ago

Thank you and I am pleased whenever someone engages and gives me their honest thoughts, it is always helpful.

Maybe I'll rewind a bit, and I'm sorry if this is a long post!

I've just had a teenager who finished making a Chess game in Easel after about a month's work, his most advanced programming project so far. This teenager started in Scratch, has done some Python, but the language they have spent the most time in has been Easel. I've also had a couple of teenagers who have said things like "I suck at coding" and yet make spend months making these quite sophisticated Easel projects full of coding. These two teenagers also did a bit of Scratch but also were lost and disengaged when it came to Python. This mirrors what I've seen in Code Clubs as well, where teenagers just lost interest when shown Python.

Eventually, if someone is going to learn to code for real, they must make the transition from a visual programming language to a text-based programming language, and I know that I have seen teenagers get lost attempting to cross that gap. There are teenagers who obviously have had no trouble with this and that's great, they should go straight to Python or JavaScript or whatever is their heart's desire!

The difference between Scratch and most other programming languages is more than just visual vs text-based. Scratch is actually this cool concurrent, asynchronous, event-driven programming language. This makes it easy to write things like "wait 0.3 seconds" then "move 2 steps to the right". Most other game engines, including PyGame and Godot, instead use a frame-by-frame model. This means you often have to code things as state machines, where you pick up and put down state so that an entity can remember what it was doing next frame. That example of "wait 0.3 seconds" then "move 2 steps to the right" would require the control flow to jump up and down the codebase between state and logic, which means the shape of the code no longer mirrors the step-by-step of what it is actually doing. I think Scratch is successful not just because of its visual coding, but because its programming model allows for step-by-step logic to look like step-by-step code. There's no reason a text-based programming language couldn't also have this property.

Easel is concurrent, asynchronous, event-driven, like Scratch, which is why both Easel and Scratch code can be written in this sequential step-by-step way that you can't easily achieve in other programming languages.

Why can't you just write `await sleep(0.3s)` in other programming languages? Their issue is you can't cancel an `await`, which means it is easy for an asynchronous task to outlive its entity and so they are not safe beginner-level constructs. Scratch solves this implicitly because all scripts are part of a sprite, and when your sprite is removed, all its concurrent scripts stop. It's so intuitive that it doesn't really need to be taught. Easel has a similar thing but in text-based form - it is a hierarchical programming language and everything inside of an entity's block`{ }` gets auto-cleaned up when it dies, including all asynchronous tasks belonging to that entity. I think that's why in Easel, I've seen teenagers spinning up hundreds of asynchronous threads all the time without any problems.

All of this is to say that Easel is like halfway between Scratch and Python. It keeps a lot of the intuitive parts of Scratch's cool programming model, but in text form. My hope (and we have seen this already a few times) is that it can help more teenagers cross the gap from visual coding to "grown up" text-based programming languages.

The reason the code sample is at the top is actually because I saw a teenager talk aloud as they were reading that code and understanding it in real-time. It was super cool because that's it, that's what I've been trying to do - make a text-based programming language that is legible to beginners and not convoluted. And I'm trying to figure out whether it is possible to replicate that moment over and over again with new teenagers.

There is a lot more to it. Easel adds a lot of other stuff like a physics engine and automatic multiplayer. But this post is getting long so I will stop there. I really appreciate the thoughts. I am definitely going to be thinking about how that homepage is presenting itself and I think it is fair what you say that it doesn't look simple, and doesn't look different to any other game engine. That is very good feedback!

anpep• 7 months ago

I’m self-teaching modern C++ by developing a native music library manager and player for Windows, macOS and other Unix systems. The main focus is on the 100% custom UI (with Direct2D/CoreGraphics/Cairo backends), aiming for responsiveness, power-user friendliness and compactness. The UI thread is absolutely sacred and I’m trying really hard to separate the core logic from the UI, because I hate how laggy and hang-prone all players I’ve tried are. I’m drawing inspiration from pre-2010 skeuomorphic and dense UIs. Key features include fast incremental imports and powerful UI elements with features like multiple column sorting, multiple element selection and keyboard-first navigation. I understand this problem is already solved, but I’m starting to DJ and curate my personal music library again. So far, nothing has been more satisfying than an old unsupported version of iTunes that doesn’t even support FLAC. I’ve tried foobar2000 but it doesn’t meet many of my requirements. Therefore, I’m building this software both because I have a need and because writing it is very fun (and frustrating at times)!

I’ve written a PoC already (mind the crappy and incomplete UI), mostly to test the wild custom UI idea, and it’s working so far! https://i.redd.it/ocx9m5av6d6g1.jpeg

The simplicity and density of that UI is nostalgic. You say it's crappy and incomplete, but all I'd want is a search bar which can actually scroll the whole-library view to the found-song (something I wish Spotify did, but they only filter.)

Implement them like the iPod used to implement playlists. There's no playlist bars, tabs, UI, or other clutter. You just had a default list you were working on, and anything you added got added to it.

Except for the constant glitching and crashing, the iPod had a really great user interface. (and to be fair, that was probably partially my fault for downloading all kinds of sketchy MP3s)

A few technical details I enjoyed working on:

* Streaming ZIP: To allow downloading multiple files as a single archive without buffering, I implemented a custom streaming ZIP64 archiver. A Service Worker intercepts the request, fetches encrypted chunks, decrypts them, and constructs the ZIP stream on the fly in the browser.

* OPAQUE auth: I used the OPAQUE protocol (via serenity-kit) for the password-authenticated key exchange. It ensures the server never learns the password and protects weak passwords against offline attacks if the DB leaks.

* Passkey PRF auth: If your passkey provider supports PRF (like iCloud Keychain or Windows Hello), the app derives the data encryption key directly from the passkey, allowing a login flow that doesn't require entering a master password.

How is it different from croc?

pypt2• 7 months ago

From what I understand, croc is P2P, i.e. both computers have to be on for the transfer to happen (the "relay" that they mention only helps negotiate the connection between two peers). With aero.zip, you upload your files to a server, and the recipient can download it whenever - either real-time while you're still uploading them (imitating the P2P/croc model), or at a later date. This is a more universal approach IMHO.

Also, aero.zip is a webapp, i.e. there's nothing to install, and you don't even need to sign up to send small files. Meanwhile, croc is a CLI utility which will be hard to use by mom-and-pop users.

im build an offline-first iPad-focused Dungeons & Dragons campaign app called Campaign Codex. i got inspired by watching Critical Role and saw a bunch of them using iPads during their sessions.

thought it would be cool to build something like this. im still building but feel free to download it via testflight and give some feedback: https://testflight.apple.com/join/kM4udJSZ

I'm building a TypeScript to native code compiler, via the Dotnet CLR toolchain and Native AOT. This lets you use the excellent Dotnet std library - which in addition to being faster is also much safer than the npm ecosystem. There's also a node compat library, which exposes Node APIs but with CLR underneath.

The end result will be a binary (linux and mac for now) which you can run without NodeJS. Simple programs already work, and I have web apps very nearly running.

I got a couple new toys for birthday/xmas: the GPD MicroPC 2 UMPC and the M5Stack Cardputer.

The MicroPC is great because it makes it super easy to code and hack on something in places where it would be too awkward or annoying to whip out my laptop, and the Cardputer is just a fun little toy because it's so open ended and hackable. I've been writing an app for Cardputer to control my thermostat remotely, and I've had a lot of fun grossly overengineering the needless amount of concurrency I have added through FreeRTOS.

Something oddly satisfying about using a micro PC to program an "even more micro" PC. What a cool time to be alive; I would have killed for this kind of stuff as a teenager!

I built a universal live speech translating app.

I’ve been playing around with the Whisper models for a few years now. Last year I had an idea about how to run Whisper Large v3 in real time. That idea became ScribeAI.

Because the quality of transcripts was so high, much higher than I could get with Parakeet, I started to think about how it would serve as a good input for live translation. I played around with this and was surprised by how good the results is, I’ve used it to follow along political speech’s from foreign leaders and other content I’d have just never been able to consume before. You can translate by bringing your own LLM service API key or using the inbuilt Apple Translate models (for a completely offline experience).

I’m working on Lunara AI: https://lunaraai.app

It’s a meditation app where an LLM guides you without the usual back-and-forth chat. You set your preferences up front (style, duration, focus), then it delivers a structured session end-to-end.

I have a long list of ideas and features to try, but right now I’m focused on feedback. The app is live on the App Store, and I’d love input on: • What would make you try an AI-guided meditation app (or avoid it)? • What settings matter most to you (duration, tone, technique, background audio, etc.)? • What would make the guidance feel trustworthy and not “chatty” or generic?

If you’re willing to test it, I’m especially interested in first-session impressions and what you’d change to make it something you’d actually keep using.

josho• 7 months ago

This is the second app that I’ve tried with an AI voice for meditation. And frankly it’s off putting. The voice is great for other settings. But when my eyes are closed and I’m focused on nothing but the voice it stands out as negative.

Now I may tolerate that if you are significantly cheaper than the alternatives but that doesn’t seem to be the case.

Video intelligence platform for coaching programs and training companies. The problem: these businesses sit on 200-500+ hours of video content that becomes a "content graveyard" - students can't find what they need, coaches burn out answering the same questions, churn stays high.

We do deep transcript + metadata extraction, then layer RAG search and an AI assistant that can answer questions with timestamped citations back to the exact video moment. Think "ChatGPT for your video library" but with accurate sources instead of hallucinations. Tech: Phoenix/Elixir backend, Next.js portals, two-tier RAG architecture.

Currently serving a few coaching programs in high-touch sales mode. Would love feedback from anyone who's built RAG systems over media content - curious how others handle the signal extraction problem (transcripts are noisy, you need to identify what's actually being taught vs filler).

Current apps in the hopper are centered around:

(1) Recovery from cosmetic surgery. There are several balls to juggle for days, weeks, and months after a surgery. The app helps the user follow surgeon instructions, promoting physical and mental recovery, as well as medical and dietary changes. Makes use of phone features including contacts, calendar events, notifications. I’m learning to build an App Clip for it and hope to partner with some surgeons to get it promoted in their offices.

(2) Assisting older Americans to be more independent for a little longer (a parent of mine has early stage dementia). Helping the user maintain a regular schedule, take their medications on time.

(3) A dating ideas / meal ideas and agreement app. It helps increase creativity for date ideas, learns from how predictable you are, and facilitates agreement between the users.

Deciduous.

It's a way of working/tools for working with an LLM that allow you to track decision tree graphs, have the robot make more informed decisions and build its own logical chain for history keeping, and modeling all the work as a DAG of events, goals, outcomes, decisions, and observations that network together to allow you to work better/smarter/faster, giving it a living and recorded memory and ways to explore all this.

It's easiest to check out the short demo on the site.

It also links to the live graph of how the tool has built itself.

http://notactuallytreyanastasio.github.io/deciduous/

aoeusnth1• 7 months ago

Cool name, with both hints at "decid[e]" and the graphs.

I'd be interested in integrating this with bug systems of decisions / goals, with actions being comments on those bugs (for work purposes) instead of having a custom deciduous-only DB.

Is this meant to be open source? I don't see a LICENSE.

kubakomu• 7 months ago

Really interesting to see, because about 2 months ago I had a very similar idea, just with a bit more opinionated shape of the graph and context building, but more focused on the research and decision-making part. I started the development, but my focus eventually landed on a completely different aspect of that system.

So I have to ask, how well do you see it performing so far with regard to actually sticking to the data present in the system? Do you find the AI agents to adhere properly to the existing data?

On a similar note, can the "consensus" of the system be adjusted in a way where we keep the knowledge which was true at time T (decision provenance), but we avoid having that bit of information affect current decision making?

rhgraysonii2• 7 months ago

It's doing a great job. It has built itself with itself, the story is here

http://notactuallytreyanastasio.github.io/deciduous/story.ht...

the time-relevant stuff is all well beyond anything it does. It keeps confidence weights and decision paths and can analyze those.

I've also been using it at work with pretty great success.

Bedtime Bulb v2 [0], a light bulb that emits less blue light than other lighting, is finally shipping. It took years to get it right, but we figured out how to make a relatively energy efficient bulb that emits infrared and dims smoothly with any dimmer.

My team is also about to ship Atmos [1], a lamp for the bedside that automatically shifts from higher-blue light during the daytime to low blue light at night.

[1] https://restfullighting.com/atmos

vl2• 7 months ago

Very cool, what’s the temperature range/wavelengths? (good idea to specify it on the product page - otherwise it’s unclear how is it different from other lightbulbs)

yeutterg9• 7 months ago

The bulb ranges from 1700K to 2100K (it warm dims)

Atmos ranges from 1800K to 5700K

Maybe not the most obvious, but for both products, it’s in the tech specs under Quality of Light. We try to be very detailed with what we publish there. Thanks!

blindriver• 7 months ago

The blue light “science” is a fallacy. I think N=8 in the original study and the difference in sleep was about 15 mins.

yeutterg9• 7 months ago

It’s a combination of factors: you must reduce both blue light and intensity of light to avoid suppressing melatonin. Just reducing blue light might help a little, but it still suppresses melatonin. Melatonin levels and circadian phase shifts scale with total irradiance even if blue-depleted; basically, dimming the lights is really effective.

That’s why our products focus on both intensity and color change (but we lead with blue light reduction since it’s easier to grasp).

Also, if you look at our specs, you’ll see that we don’t use pure amber or red light; we use very low-blue white light with high color rendering. We have yet to do the study on this, but you can read surprisingly well with our lighting at a very low intensity (enough to make your mom angry that you are hurting your eyes), whereas with lower CRI sources, you would have to make them brighter to achieve the same visual acuity.

There is some emerging research that IR may play a role in melatonin production locally in cells, which is why we added it to the bulb. Early days for this scientifically, but Scott Zimmerman and associated researchers suggest wideband IR may be effective, even if it’s only 20-30% of the visible intensity.

TZubiri5• 7 months ago

Is it possible for the bulb to gradually lose brightness as the night goes on? The default of a light bulb being as strong as 4am as it is at 1am is certainly simple, but does not make for a good nighttime experience.

yeutterg9• 7 months ago

With the Atmos lamp, yes! It constantly makes very minor, imperceptible changes every few seconds. I also developed an app, currently in public beta, for Philips Hue that does this as well [0].

We're working on a Nest-style ML feature for the Atmos lamp that learns your intensity preferences and automatically applies them. And we have a whole bunch smart circadian products we're working on—something for the desk and workspace next.

For Bedtime Bulb v2, not out-of-the-box because it's all analog electronics, but we REALLY want people to dim it gradually throughout the evening. If you want to automate dimming, the Leviton Smart Dimmer we offer on the site will allow you to control it with any of the popular smart home platforms.

Why isn't Bedtime Bulb smart? Bedtime Bulb v1 was our MVP, and we focused on getting the quality of light right over adding any smart features. It turns out, many of our customers have told us they don't want anything smart. So when we made v2, we focused on doubling down on quality of light features: infrared, warm dimming, "Perfect Dimming" (smooth dimming with any TRIAC or ELV dimmer), really high CRI/R9/TM-30, etc.

Smart bulbs are definitely a future possibility, but right now, we have the analog line (Bedtime Bulb v2) and smart line of fully-integrated lamps (Atmos).

ishtanbul• 7 months ago

very interesting. Can I control these with home assistant?

I already have a wind down dimming schedule on my entire home. It changes brightness and color temperature gradually over 2 hours. How do these bulbs compare with philips hue?

yeutterg9• 7 months ago

Yes, the bulb can be controlled with a smart dimmer like the Leviton model we sell on our site, or the Lutron Caseta plug-in dimmer.

These bulbs are not smart and do not have a full RGB array. But what you gain is way higher color quality even at low color temperature (1700K), much lower flicker, and infrared.

Atmos is a smart lamp, and we will get our Matter certification in early 2026. This one is also not RGB, but it has extremely high color quality in the whites and no blue spike. Flicker is lower and at a way higher frequency (32 kHz). We haven't updated the specs on the site yet as we are wrapping the calibration, but the CRI is 98 on the Atmos lamp.

meatmanek• 7 months ago

How does the Bedtime Bulb compare to Philips' "warm glow" bulbs, which also adjust their color temperature as they dim?

yeutterg9• 7 months ago

The Philips bulbs are more general purpose bulbs that would replace your "soft white" 2700K bulbs. I think they dim down to around 2200K. Otherwise, the specs are pretty typical for LED bulbs in terms of color quality, flicker, and dimmability.

Bedtime Bulb v2 starts at 2100K, much warmer, and dims down to 1700K. BBv2 has infrared. The flicker is very low: under 1% at 120 Hz; the best I have seen in any dimmable bulb. It is also designed to dim perfectly with all TRIAC and ELV dimmers (basically, any standard dimmer), which no other LED bulb can claim to do.

Side note: the term "flicker-free" is a total lie, so we stopped using it. I have seen lighting with up to 50% claiming to be flicker-free. Pretty much all lighting has some flicker. The term is just not true.

Hi HN — I’m Gerome, and I’m working on CodinIT.dev.

TL;DR: CodinIT.dev is a local-first, open-source AI full-stack app builder that turns natural-language prompts into prototype → production web apps. It supports local/self-hosted workflows, connects to databases (Supabase), includes an integrated terminal and git automation, and plugs into 19+ AI providers so you can iterate fast. Download desktop app at https://codinit.dev .

A few quick facts

What it does: Generate full-stack code from prompts, preview instantly, and deploy anywhere — built for indie hackers who want full control of there code without vendor lock ins (open source).

Where the code lives: active repo and org on GitHub — org name is codinit-dev.

How to try it: download and run locally; the dev flow runs with pnpm run dev and serves locally from your machine.

Progress & current priorities

Stabilising the live code execution sandbox and improving safety/UX for file uploads and agent orchestration.

Tightening integrations with community LLM providers and adding more framework templates.

Improving contributor docs and reducing onboarding friction so people can run it locally without hurdles.

If you want to poke around, try the app or the GitHub org and open issues/PRs. I’ll hang around to answer technical questions here.

I made a platform for innovators, founders, developers to validate their idea against real users (not AI).

My purpose to build this platform is two-pronged–first to solve the "Power Law", in simple terms, where platforms such as Instagram, Reddit, YouTube, TikTok, etc. only put forward the popular content (most upvoted, liked, viewed, trending, etc.) and people who are posting regularly are still left behind fighting for some interactions.

Second, to provide a platform for people, innovators such as myself, who keep asking the question "is this worth working on? worth spending time and money on". There are subreddits with hundreds of thousands of followers and Redditors and many of them are still not getting the visibility they need to start.

I remember that I had a lot of ideas throughout high school but I wasn't able to get real answers and validation from people so I dropped it. So specially for those people who need a little bit more visibility.

So trying to solve that.

It has minimalistic dependencies. Currently the only non-development dependency it has is jsonschema.

I keep the configuration of the application in a JSON file. This configuration already allows to configure many things, like for example the various learn levels, and what their meaning in terms of the spaced repetition system is, which attributes of a word will be revealed in what order, when practicing, what attributes to show in the columns of the vocabulary table, and what font to use for the big character display widget (useful for languages like Chinese).

I've spent the last week starting to hand port SeL4 to rust. Mostly because I want to learn how kernels & capabilities work. This seems like a fun way to get my hands dirty with operating systems without needing to invent everything from scratch.

To be clear, there's no benefit to using rust over C for SeL4. SeL4 is formally verified - which provides a level of assurance far beyond what the rust compiler can check at compile time. I'm really just doing it for fun and learning. I've been wanting to really understand sel4 for awhile, and there's something wonderful about learning it from the ground level.

So far, I've got a stub booting. The CPU successfully boots into 64 bit mode and starts running my rust code. I'm starting with x86_64 because thats whats on my desk. At the moment I'm porting the code which locates the root process via multiboot, so I can set everything up in memory correctly.

The plan is to get something out on Steam, roll with the punches (bugs,) then open it up for general-use. I say "framework" instead of "engine" because the scope of the project is to make the decisions the beginners get stuck on and free them to make a game. That's a smaller goal than what you see with Unity, Godot and Unreal, but I am already at the point that I'd rather use my thing than Godot.

https://finbodhi.com — It helps you track, understand, and plan your personal finances — with a double-entry accounting. You own your financial data. It’s local-first, syncs across devices, and everything’s encrypted in transit. 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.

Soon, we will have benchmarking capability. You would be able to compare your networth growth with inflation, compare your investment returns with benchmark etc. We would support both nav and value based benchmark. The topic is interesting in itself, and somehow, not emphasized/available in most tools.

Asset price fetching and benchmarking works best for Indian markets. We would like to build better support for international assets and benchmarks, but haven't figured how to get the data.

NOTE: you can try demo without signup, but it doesn't work in Firefox Incognito mode.

Several years ago I wrote an internal tool named Fogbeam Universal Competitive Inteligence Tool (eg FUCIT). It was up and running and doing it's job for a while, then a lot of stuff happened and it kinda fell into disrepair. It's a Grails app and the original Grails version was something like 2.2.3 and I think it was running on Java 1.6 or something along those lines.

Anyway, for a lot of reasons that don't matter now, the time has come to rebuilt | reinvent | reinvigorate this thing. So for the last week, I've just been working on updating dependencies, fixing the resultant breakages, and also fixing miscellaneous bugs that had never been fixed (or possibly even noticed) before.

As of today I have most of the base functionality up and working again. I just got all the Quartz scheduling stuff set back up and now I'm testing the scheduled job that fetches data from RSS feeds and creates associated records based on the contents of those items.

Up next: test|fix some functionality around defining "semantic assertions" about entities in the system (using Apache Jena) and then I'll at least be back where I was.

After that, I have some UI improvements to make (the UI now is basic GSP pages with Bootstrap and jQuery), and then some GenAI integration stuff. Beyond that: who knows?

Besides that...

I've been working on a no-code multiplayer game editor. The idea is to let anyone create multiplayer games in a few clicks without writing code—and share them instantly.

The platform handles all what's necessary (and annoying to setup) out of the box: multiplayer, controls, mobile/responsive/ inventories, save/load, leaderboards, quests, dialogue, etc... Users just select what they want and configure it with clicks.

Technically, the engine just reads a config file and renders it for players. I've built all the foundation blocks that interpret the config.

I'll soon be onboarding game designers to stress-test the editor/engine. Still polishing templates so people have a good starting point, but it's functional and I'd love feedback!

I'm working on Mizu, a small Go web framework built around a simple idea: net/http is already good, frameworks should not fight it.

I've kept running into the same problems in popular Go frameworks: hidden context mutation, magic middleware ordering, reflection-heavy binding, and APIs that slowly drift away from the standard library. The Gin ecosystem in particular has accumulated a lot of technical debt and footguns, which this post summarizes well: https://eblog.fly.dev/ginbad.html

Mizu is deliberately boring by design:

  - Built directly on Go 1.22 http.ServeMux
  - Explicit middleware chains with clear scoping
  - No reflection, no codegen, no global state
  - A real request context type that still interoperates with net/http
  - First class graceful shutdown and error handling

If you're happy with net/http but want slightly better ergonomics and structure without losing control, that's the gap Mizu tries to fill.

I mentioned this a few months ago, but have made progress since - I'm working on an alternative to subscriptions for online publications. Instead of subscribing to entire publications / blogs, publishers would register their publication on this network and configure thresholds and pricing. Add a bit of code to the site and a paywall will show up, allowing readers to pay for individual articles. The prices would be minimal, amounting to less than a dollar in most cases. i.e. reading articles using micro-transactions

I know it's been tried before, but I thought I'd attack it with a few different angles - web based, no chrome extension, thresholds to help verify the article is worth it, extensive use of an aggregator to help with discovery and validation.

I don't have a link to share just yet, but I'm working on an LLM coding agent that can modify its own context and is given hints on when and why that would be useful.

I expect it to make it possible to not think about when to reset back to a clean session. I also expect it to be more efficient as it will clear out all the "garbage context" that only serves to "confuse" the LLM, cost more tokens, make responses slower, etc.

Once I get a working prototype, then I will test the feature by using it while reimplementing it in other open source agents to get a feel for whether it has the effects I'm expecting.

It's essentially a book progress tracker. There are many apps that allow you to add the books which you are reading currently, but not at what pace. It's simple, no complicated stuff, no AI shenanigans.

Created as I was overwhelmed by the number of books I want to read and thought it would be helpful to plan ahead.

You add a book name, number of pages and how many pages you want to read in a day. It calculates and gives you the number of days and on which date you will finish. It's also flexible to increase the number of pages so that it can recalculate.

It's a PWA for now. Still working on notifications and stuff.

niyikiza2• 7 months ago

I've been spending weekends thinking about authorization for AI agents, specifically delegation.

The failure mode I keep hitting: once you give an agent tools, it gets ambient authority over all of them. There's no clean way to say "for this task, read-only on the reports table" or "spin up no more than 3 VMs." When the agent spawns sub-agents mid-execution, they inherit full access by default.

IAM doesn't help much. Authority stays tied to the agent's identity even as intent shifts during execution.

I'm exploring a capability-based model instead: authority is explicit, task-scoped, and attenuating. Closest to Macaroons/Biscuit, but adapted for workflows where delegation happens dynamically mid-task.

Early prototype (Rust core, Python SDK, LangChain integration), still thinking it through. Notes here: https://niyikiza.com/posts/capability-delegation/

lukebuehler• 7 months ago

Excellent article, and I fully agree.

I came to the same realization a while ago and started building an agent runtime designed to ensure all (I/O) effects are capability bound and validated by policies, while also allowing the agent to modify itself.

https://github.com/smartcomputer-ai/agent-os/

niyikiza2• 7 months ago

Thanks! Just looked at Agent OS. Love the 'Signed Receipts' concept in your AIR spec.

We reached the same conclusion on the 'Ambient Authority' problem, but I attacked it from the other end of the stack.

Tenuo is just the authorization primitive (attenuating warrants + verification), not the full runtime. The idea is you plug it into whatever runtime you're already using (LangChain, LangGraph, your own).

I'm currently in stealth-ish/private alpha, but the architecture is designed to be 'userspace' agnostic. I’d love to see if Tenuo’s warrant logic could eventually serve as a primitive inside an Agent OS process.

I'll shoot you a note. I would love to swap notes on the 'Capabilities vs. Guardrails' implementation details.

I’m working on OpsOrch(https://www.opsorch.com/), an open-source orchestration layer that provides a single API across incidents, logs, metrics, tickets, messaging, and service metadata.

It sits on top of existing tools like PagerDuty, Jira, Prometheus, Elasticsearch, and Slack, and normalizes them into a shared schema. It doesn’t store operational data, it just brokers requests through pluggable adapters and returns unified structures.

The motivation came from incident response workflows that still require hopping across multiple vendor UIs and APIs with different auth models and query languages. Instead of another “single pane of glass,” this is meant to be a small, transparent glue layer.

On top of the core service, I’m also exposing everything via an MCP server so LLM agents can query incidents, metrics, and logs as typed tools without needing vendor-specific knowledge.

Currently open source, written mostly in Go and TypeScript. Still early, but usable with PagerDuty, Jira, Prometheus, Elasticsearch, Slack, and mock providers. Feedback from SREs and infra folks has been very helpful so far.

password-app• 7 months ago

Working on The Password App (https://thepassword.app) - an AI-powered macOS desktop app that automatically rotates your passwords across websites.

The problem: most people have 100+ accounts with weak/reused passwords. Changing them manually is tedious, so nobody does it.

The solution: import a CSV from your existing password manager (1Password, LastPass, Bitwarden), select which accounts to update, and the app uses browser automation with Gemini 2.5 Flash to navigate to each site's password change page and update them in parallel. Exports a CSV with the new passwords to import back.

Key technical choices: - browser-use library for AI-driven browser automation (handles dynamic sites better than Selenium) - Local-only architecture: passwords never leave your machine, no cloud sync, everything stays in memory and is cleared after use - Electron + Python: React frontend with a Python agent for browser automation via stdio IPC - OpenRouter for LLM access (Gemini for navigation, Grok for validation)

Security was the most important and the hardest constraint. Passwords can't be logged, can't be sent to the LLM context, and can't persist on disk. Custom fork of browser-use to inject credentials via secure parameters invisible to the AI agent.

Currently at v0.38 with code signing and notarization for macOS. Working on improving success rates - the main challenges are 2FA requirements and anti-bot detection (Cloudflare, reCAPTCHA).

Would love feedback from anyone in the security/password management space.

Just launched a restricted browser for kids for iOS: https://weblock.online Now testing on my kids. The idea is that the browser is whitelist-only, so kids can open only approved websites. I receive a notification when they want to visit an unknown website and I can allow or deny it. Works great for my family, hope it will be useful for someone else.

TZubiri5• 7 months ago

How does it work on a more technical level? I would be interested in seeing a bit more tech detail, perhaps because I'm more technical, but also there's so much competition in this space that you need something to differentiate.

For example, is the blocklist UX side Domain based? Company based (Allow all by Google/Alphabet), category based (Search engines)?

And on the backend, is it DNS based or HTTP based? Or maybe an OS hook.

mgz3• 7 months ago

Hey, more technical details follow.

Weblock uses a whitelist, not a blacklist, and it is domain based. Once you allow a domain, it can be browsed by a child. You can allow it forever/15 minutes/1 hour.

How it works: WKWebView, before loading a page, asks the backend if the domain is allowed. If not, it shows "Not allowed" screen and a "Request access" button - child can tap it and you (parent) will get a notification.

So traffic is not going through the backend or a filtering VPN, the app just asks the backend if a page (domain) is allowed to visit.

Visits are logged, so you, as a parent, can see what your child has been browsing. How much time did he spend on a homework website.

Some WKWebView callbacks used for that: * onShouldStartLoadWithRequest - to intercept a request and check if it's allowed * onLoadProgress - to show loading progress bar * onNavigationStateChange - to track browsing history

Also I had to implement a workaround for buggy Screen Time in iOS 26 - even if you add Weblock to "always allowed" apps, iOS will still treat each website as a separate "app" and block it, asking to you "allow' each website on system level. It happens inside WebKit codebase, but luckily this bug has another bug in it - if you re-open a website, it suddenly works and all other websites in this session work tooSo I need to listen to `onScreenTimeBlockingStateChange` event and automatically reload a website if that happens.

Also I added an ad blocker to Weblock. It uses uBlock Origin filters, converts them to WKWebView content rule JSON format and feeds to WKWebView. The app checks the backend if rules are updated and updates a local copy.

What's next: need to get "Default Browser" entitlement from Apple. Then you can block Safari on kid's phone using Screen Time and have Weblock open all HTTP(S) URLs.

App is written in React Native, no performance issues. Backend is Ruby on Rails.

I’m working on a small browser extension called Instant Preview.

https://chromewebstore.google.com/detail/majhgbekihmliceijip...

It lets you open links in a side panel, so you can quickly look at a page without leaving what you’re reading. I built it because I tend to open too many tabs when reading docs or search results.

It supports a few simple triggers. My favorite one is long-click: you click and hold a link, and the preview opens in the side panel.

Chrome recently added Split View that you open from the context menu. It works, but for quick checks it feels a bit heavy. You have to right-click, move the mouse, and pick an option.

With long-click there’s no menu. For me it feels faster, more intentional, and better when scanning lots of links.

Most of the work lately is about polishing these interactions and dealing with browser edge cases.

ianbicking• 7 months ago

I've been working on a LLM fiction writing workflow and associated tools. It's built on agentic coding tools with lots of structure, guidance, prompting, and critique. Almost all of the flow is on the filesystem and using a custom command-line tool, making it accessible to agentic programming tools. (No MCP though; it seems superfluous?)

I was fairly neutral about the tool for a while, but lately I've been going all-in on Claude Code, using things like rules and subagents.

It's also built to "rerender" the story, for instance rewriting it (slightly) for voice, translate it, or target different reading levels or background. I'm interested in translating stories for language learners in addition to simply translating into other native languages.

I'm also hoping to create some stories that stretch the medium. Perhaps CYOA (though I'm struggling with understanding what a CYOA is good at), though also other multi-perspective stories with reader autonomy in how to read through the story. LLMs make it easier to overproduce content, so you can give the reader flexibility without feeling regret that much of the content will be skipped, or rewrite passages for readers who jump into stories part way through.

Producing quality content is hard, and frankly kind of expensive, which is why I'm focused on finished products instead of interactive experiences. Though I do look forward to some future opportunity to take these rich characters that are grounded in full stories and find other things to do with them.

TTRPG Narrative Engine — https://test.qualy.dev

I'm building a session prep tool for tabletop RPG game masters. The idea is to make a narrative engine rather than another static wiki. Most existing tools are great for storing lore, but they don't help you run the story. I wanted something that supports the "create now, refine later" workflow — get ideas into structure fast, then refine as you play.

Core features: - interconnected world-building (NPCs, factions, locations) and story-building (situations, fronts, clocks) - Bidirectional linking — connecting a story hook to an NPC makes that hook visible from the NPC's view - Clock system with milestone consequences that can spawn or edit entities - Situations fire different consequences based on outcome (players engaged vs. ignored the hook) - Material waste detection — flags under-connected content so you know what's prepped but unused.

The main workflow is mindmap-based. Each entity gets its own context layer showing direct relationships. (Soon available in demo version) Working on next: automatic player-facing content. As players complete situations, public notes from involved entities get published — so the GM doesn't have to maintain a separate campaign log.

Stack: TypeScript, Effect-TS, SolidJS, Cytoscape (graphs), Leaflet (maps)

The hosted version is rough — I've been using it to get early feedback from GM friends. Happy to hear thoughts from anyone who preps campaigns

Volatility Regime Prediction via Causal Discovery in Option Markets - https://github.com/philippdubach/vol-regime-prediction/blob/...

Volatility regime models (Markov-switching GARCH, regime-switching stochastic volatility) are ubiquitous in finance. However, they share a fundamental limitation: regimes are identified ex post from return dynamics, providing no predictive power for regime transitions. The standard approach fits a Hidden Markov Model to returns, labels high and low volatility states, and estimates state transition probabilities that are essentially unconditional averages. This matters because the economic value of volatility timing depends entirely on predicting regime changes before they occur. A model that identifies regimes only after observing the returns is useless for trading volatility.

Existing research documents regime-dependent behavior but does not identify causal drivers of regime transitions. The papers on volatility forecasting factors, variance risk premium dynamics, and market instability from option flows dance around this question without directly addressing it. The recent work on causal ML in finance (double machine learning, causal forests) has focused primarily on equity return prediction rather than volatility states. The connection between options market variables and subsequent volatility regime transitions has not been rigorously established through causal methods.

We develop a causal framework for volatility regime prediction using option-implied variables as potential causes of regime transitions. The key insight is that options markets are forward-looking, so information embedded in the implied volatility surface, put-call ratios, option order flow, and term structure slopes may causally influence future realized volatility regimes rather than merely correlate with them.

Currently building a robust dataset.

Back in 2019 I created a Google Spreadsheet titled "family debts" that allows my family (4 siblings and my parents) to record when we owe each other money, and periodically settle up.

We have over thousand entries, and use it constantly for splitting gifts, buying something at the store for someone, etc.

Om Friday after Thanksgiving I spent half a day building a telegram bot that accepts an address and a list of Amazon links, and in turn orders the item (at a discount since it uses my Amazon credit card), and adds it to the above "family debts" spreadsheet.

It’s “Hotwire for command-line apps”, meaning you can ship a CLI in a Rails app without building an API. The dream is to make it work for all major web frameworks.

Terminalwire streams stdio, browser launch commands, and a few more things needs to ship a CLI for a SaaS quickly.

The best part is when you want to ship a feature for the CLI, you don’t have to worry about pushing out updates to clients and making sure it’s compatible with your API.

A more interesting development are companies that are using it as a replacement for MCP in AI stacks. They’re reporting less token usage and better overall results.

I built a daily football (soccer) quiz a bit like Wordle but identifying 5 footballers by their career path.

Stating to get a quite a few people playing it each day now.

I suppose if it is ever to make any money it will need ads at some point but for now it is ad-free.

I’ve enjoyed making something simple and shipping it rather than trying to do something more grand.

It's a travel tool for business travelers that figures out your suggested departure times for your entire itinerary based on predicted traffic patterns. Think Flighty but for all the non-flight parts of your trip.

You first build a travel itinerary with your legs - flights, activities, hotels (and hotel returns) and it tells you things like "leave your hotel at 7:40am" before your 8:30 meeting - in a single itinerary, no need to do the google maps acrobatics for every two items in your itinerary. While it's aimed at frequent business travellers I personally use it for all family leisure travel and daily itineraries around town as well - "do I have time for lunch at home after my son's class or should we bring packed lunch". I built it as during my time working in developer relations I traveled a lot, and always built unnecessary buffers and kept nervously glancing at my watch or phone to see if my planned time to leave still holds.

Tech-wise, currently it's Remix web app with a NodeJS/Fastify backend and Supabase for storage, and relying on google maps for route duration calculations. I want to expand it to native mobile clients in the future as well.

I am using it as playground on product thinking, ruthless prioritisation based on user benefit, figuring out unit pricing and economics, sensible architectural design, and exploring how including AI-enhanced features here and there can help make the product better, not just include them for their own sake.

We are building a K8s management platform based on AI Agents and smart visualization. It's surprisingly hard to distill common issues down to generalizable agents which can solve real world issues but we've made some very exciting progress in the space.

halfinney• 7 months ago

Been casually working on some AI projects lately. Open-sourced both: LLM Archive Downloader. Got paranoid one night about open-source models potentially disappearing (licensing changes, restrictions, who knows). So I built a script to download and archive them locally. One command, pick what you want — Llama, Mistral, DeepSeek, Whisper, the works. ~200GB total or grab the essentials (~40GB). Now they're sitting on my hard drive. Offline forever.

→ github.com/Ashwinsuriya/llm-archive-downloader

YouTube Shorts Generator Converts long YouTube videos into Shorts automatically. Whisper handles transcription, LLaVA analyzes frames to find interesting moments, Mistral picks clips and writes captions. Everything runs locally in a parallel pipeline. No APIs, no subscriptions. → https://github.com/Ashwinsuriya/yt-shorts-generator Nothing fancy.

Just scratching my own itch and sharing in case anyone finds them useful.

For the past week, I’m working on creating device with a screen to show my indian parents if i’m in a meeting or not. So they don’t trouble me and come in my room unannounced when im in a meeting.

It’s build using ESP32 and a small screen which shows On and Off and the time till meeting is over. I learnt Fusion 360 and designed a small snap fit case and got it 3d printed.

I have a small electron app running in my mac os system tray which connect to esp using BLE and it also checks if Mac Camera is in use (using Apple logs) and then communicate it with the device.

Calling it Door Frame. Had quite fun making it as i learnt 3d design, c++ code using Platform IO and other fun stuff. Even designed a small binary protocol to exchange data over BLE

Leaning towards something in the style of Lacôte[0] but not sure, ordered a book on Vicente Arias[1] and might order a couple other plans to consider. Have a fair amount of stock prep to do before I have to commit to a design and will probably need to order a few sticks of wood as well, so probably have ~two weeks to make up my mind.

https://github.com/Mockapapella/tenex

Tenex, a TUI for managing swarms of AI agents.

I noticed that as I'm using agents more and more my PRs are getting more ambitious (read: bigger diffs), and when I was reviewing them with agents I noticed that the first review wouldn't catch anything but the second would. This decreased my confidence in their capabilities, so I decided to make a tool to let me run 10 review agents at once, then aggregate their findings into a single agent to asses and address.

I was using Codex at the time, so Tenex is kind of a play on "10 Codex agents" and the "10x engineer" meme.

I've since added a lot of features and just today got to use it for the first time in a production system. Some rough edges for sure, but as I'm using it any time anything feels "off" or unintuitive I'm taking notes to improve it.

Fun fact, on my machine, while launching 50x Claude Code instances very nearly crashes it, I was able to launch 100x Codex instances no problem. I tried 500x but I ran into rate limits before they could all spawn :(

I feature the ones I think are must-watch with short summaries written by me, then include a list of everything else uploaded that week.

It started as a personal project to fix my own messy YT subscriptions and RSS feeds and now 7,500+ people read it.

I also publish extra editions from time to time like “The Most Watched Talks of 2024” which made it to the HN front page.

I am working on a self-hostable borrow store management system: https://github.com/leihbase/leihbase.

I am running it in my city for a library of things. We hope to help people abstain from buying things they only need once a year.

It includes a reservation system, and an dashboard to manage those reservations in the shop. Currently I'm expanding it with a proper product management interface.

TZubiri5• 7 months ago

An interesting twist on this, would be to hold the used item while "paying" for it with a collateral. It would remove the need to have an owner to which the item must return to, allowing it to behave more like a linked list, reducing the amoutn of trips by two.

I also think that for taxeable purposes this would work better than buying and selling used items, especially in countries with gross income taxes. In the rest of the cases at least it would reduce the administrative burden to prove that ones net-income or value-add was marginal or negative.

I was thinking about what to get my long-distance girlfriend for her birthday which coincidentally was also the anniversary of our first date. So I thought of building her a personal website, installable via tauri so she can view it offline whenever she wants, that has a timeline of all the things we went through: first date, events, trips, moves etc.

Now I want to polish this, make it customizable, add more features like a "Reasons I love you" jar which gives you random notes your partner wrote, and offer it to others as well.

Another thing, it should be a digital living collection of memories and notes for each other and should evolve with the relationship.

Just started with this and building with Elixir and Phoenix.

PS: I realize I might need to update the website. First I wanted it to be more generic and for multiple occasions like anniversaries, birthdays etc but slimming the target down to couples for now to not overwhelm myself. It's the first ever service I'm building.

benrutter• 7 months ago

Ooh I like this! I love Hacker news and Lobsters but they're both very US centric, seem great to have a European one.

UI is very nice and simple, one tiny bit of feedback is that a 'guidelines' page would be worthwhile, especially while it's new! I thought I'd post my own project on the site - sometimes that's a little bit of a no-no though, and I couldn't find any guidelines to steer me towards what types of things to share, etc.

Edit: Tiny extra feedback, is upvoting something immediately changes the rankings in the browser. It's pretty impressive speedwise, but especially if you're a couple pages in, you can bump something off of the page you're on which makes it a little weird to do something like 'upvote article and then check the comments'.

davedx11• 7 months ago

Thanks for the feedback and posting, I appreciate it!

I'm definitely going through the comments I've had later and will take everything onboard. Guidelines is a great idea - for now it's basically "HN guidelines but Euro-centric content please" but I should definitely write that down.

What is language policy? (e.g. it would be nice if people would post any language they want, and the system shows other users what language the link is, and then offers an alternative link to a translated version.

Screenshots in the App Stores, e.g. https://apps.apple.com/us/app/pistepal/id6754510927

Still a little bit rough around the edges but hopefully will be / is in decent enough shape for the start of the ski season (just about happening now..)

Currently figuring out the right balance of free tier & daily trial. Priced at $10/month and therefore significantly undercutting the competition, hopefully this is enough to gain entry into the market. (May need a more generous daily trial though, admittedly 10 minutes is not really enough to actually try it out on the mountain).

Seems ad spend is necessary to get any kind of traction...

I am not sure if I will go live with it.

It allows those professionals experts across the USA provide help to Do It yourself consumers for a fee. Consumers can be anywhere.

So I married sort of like Uber (rent skills) + upwork (rent + fees) + FaceTime + e-commerce. realtime audio transcription that identifies parts you need and builds a list for pros and you to review which you then go shop.

: Meet Handy — AI + Live Experts for Every Fix.

: Instant, intelligent home-improvement help — see it, solve it, and shop for it, all in one live session.

Live Video Calls with Pros Instantly connect with verified experts via real-time video. No scheduling hassle — just point your camera and get help.

AI-Powered Visual Assistance HandyLens AI analyzes what the camera sees, highlights problem areas, and guides both consumer and pro with contextual prompts.

Domain Expertise Specialized AI Packs (Plumbing, Electrical, HVAC, Painting, etc.) ensure every session applies the right technical and safety knowledge.

Actionable Fix Path Each call ends with a clear, AI-generated “Fix Report”: what to do, parts needed, and next steps.

Paid Live Video Sessions (Primary Income) • Pros earn per-minute or per-session fees for live video consultations. • Example: • $3–5 per minute • Typical 10–20 minute call → $30–$80 per session • No travel time, no fuel, no tools, no overhead.

Pros log in when available (between jobs, evenings, weekends). • Ideal for: • Independent contractors • Apprentices with experience but limited licensing • Semi-retired pros • Pros during slow seasons

This unlocks underutilized labor.

I am working for a while on a command line game about spacepirates playing basketball across the galaxy. The game is a basketball managerial game with some pirate-y stuff. It's a P2P game with no central server, built on top of libp2p.

It runs as a terminal application, meaning that you just need to run it from your terminal, but you can try the game over ssh without installing: `ssh frittura.org -p 3788`

The main selling point of this app is that I do everything to let you continue do what you're doing while the algorithm search for other players. You receive a notification when a group is found or when a player is found.

Its not out yet ! The beta will be released in less than two weeks !

I'm writing a toy eigenvalue solver in Rust using the QR algorithm. I didn't intend to, but I recently discovered the Gershgorin Circle Theorem and thought it'd be neat to create an interactive visualisation for my [blog](https://abstractnonsense.xyz).

I don't like JavaScript, and I've been meaning to learn Rust for a while, so I'm compiling the Rust algorithm to WebAssembly to run in the browser natively! It's been a fun trip back into the arcane world of numerical algorithms and linear algebra!

I'm working on a collection of stackable interactive slides for teaching numerical methods and operational research.

https://okaleniuk.codeberg.page/blackboard/

The idea here is, one can pick the slides they want and arrange them into a sequence right in the URL. This way, there is no registration, no user data collection, no persistent state even. You just pick the slides, teach your material, and move on.

It's very raw, I still want to add a convenient sequence constructor, a "blank" slide so you could display your own content in it, and a similar quiz page. But I already used some of the slides for teaching, students seem to like them.

Hopefully, I'll have the rest done by the beginning of the spring semester.

I cannot say what I'm working on because it will be downvoted. Only pointless gimmicks which do not compete with the tech oligopoly can get any traction nowadays.

If I make a really good AI coding platform which saves people hours compared to existing platforms and provides more security. The chance of success is 0 because it's competing with incumbents.

If I make an app which allows cats to order food and back massages from their owners, this has a high chance of success.

vlod• 7 months ago

This thread is about people hacking on code that gives them pleasure and maybe some monetary reward. People enjoy discovering others work. Whether your project gets traction is sort of irrelevant.

Personally I found this thread more interesting than the spew of AI or rust posts.

I assume there's a lot of people who might be interested in what you're coding even if it's taking on the incumbents of providing services to cats.

I encourage you to share.

Lineage-aware. Versioned. Trustworthy Data - for Engineers and AI.

Your engineers waste up to 40% of their time monitoring, investigating and fixing data. Even then you don’t trust the accuracy, source, or freshness of metrics on your dashboard. You wish AI can answer your data questions but it cannot show you proof, or where it came from. AI helps software engineers to move fast and break things, because they can always rollback, with git. But you cannot do that for data. Bad data entering the system, spreads across the company before spotting, and takes weeks to clean up.

DV changes this, giving you lineage-aware, versioned data. It records data-lineage when data is captured, transformed, and committed, at commit/snapshot level. So when things break, DV knows what other data is impacted downstream, and it can rollback the whole chain to the previous state, instantly - no data copy/restore needed. It can also backfill the data across the chain automatically.

With DV, both your team and your AI agents can finally see: - where data came from - how it was transformed - how to revert safely with a single click

Your engineers can move fast on data, without breaking trust. Your analysts can build pipelines by simply describing business questions to AI.

DV is Git for data, so you can focus on your business, putting analytics on auto pilot.

1. starting from creating new ones

2. forking existing one (like one would do with the git repo) to experiment with new ideas or debug the issue in an isolated environment

3. being config defined and reproducible

4. hybrid by default - run as much or as little one desires on their personal machine while keeping rest of the env (db, storage, ...) in the cloud

5. easy to share: expose services (HTTP/TCP/UDP) on public or private networks

6. have any number of AI agents with specific goals be part of the dev env

jstanley• 7 months ago

I'm working on headless browser fingerprinting.

We're focusing on "anti-cloaking" for anti-phishing and other Internet security applications at the moment. Phishing sites can "cloak" themselves so that they present malicious content to ordinary users and benign content to bots, and thereby evade detection. Anti-cloaking is doing things to defeat cloaking.

The methodology is to operate a site that logs all requests, and collects information from the JavaScript environment, and looks for signals that a session is being operated by a bot instead of a human. We have 183 unique signals so far.

We've seen fake mobile phone APIs being injected into the DOM, and have been able to read out the source code implementing them. We've seen lots of people running the browser with TLS validation and same-origin policy disabled, which are both easy to probe for. And we've even seen people running services on localhost with CORS headers that allow cross-origin requests, allowing us to read out their server headers and page contents and which would allow us to send arbitrary requests to their local servers. We've seen people using proxies that don't support websockets. We've even seen surprisingly-big companies scanning us from netblocks that just straightforwardly name the company, which would be trivial to block just by IP address.

It turns out that every security vendor that scans VirusTotal submissions or domains from CT logs has major flaws in their headless browser setup which mean it's worryingly easy to cloak from them.

I don't know the best angle for monetisation. Currently we are selling "quick overviews" of what people are doing wrong, but it kind of feels like we're giving away too much value too cheaply. However it's difficult to convince people that there is value worth paying for without telling them what they're doing wrong upfront before they pay. Ideas include:

* automated quick overviews, where we give you a URL to point your bot at, find out all the signals you hit, and give you an automatically-generated report of what you are doing wrong

* or a manual "pentest" of your headless browser, where we do the same thing but spend a few days manually looking harder to see if there are new signals we're not yet spotting automatically

* or we could sell a report of the state of the industry as a whole

* or access to our tooling

* or something else

I have been told that if I say it's for anti-phishing then I have 12 customers max but if I say it's for AI browser agents then someone will give me a billion dollars. So possibly we need to explore other applications, like either telling AI scrapers why they are getting blocked, or else helping sites block AI scrapers (though I am personally opposed to building the apartheid web).

Open problems are:

* what's the best form to sell it?

* how do we satisfy people that if they pay for a test then they will get value from it?

* should we pivot away from anti-phishing?

* for bots that we notice have found us from VirusTotal or CT logs, how do we work out who is operating them so that we can sell to them? Sometimes attribution is easy but in the majority of cases it is not

I've been working on the same business since 2021:

https://notionbackups.com

The first business I started never gained traction, so I sold it in 2021 (which was a completely different time compared to now).

Notion had announced that they'd launch a beta version of their API, so while waiting for the early access, I built a landing page, login/signup, and all other plumbing for the web app.

It was a rather underwhelming launch (both for the API and my business), but I gained my first customer within a month.

Honestly, it's been a slog running this business (Notion's API is surprisingly hard to work with, so it seemed that I was stuck for months on end), so knowing what I know now, I'd probably have started a different business. My burnout didn't help either.

Claude has been incredibly helpful these last few months in solving esoteric undocumented edge cases that were plaguing the codebase for years.

I have a healthy MRR/growth rate right now and the biggest product in the niche, so I'm grateful for that.

Plug-That-In [https://plugthat.in] (Mac App; Paid)

An annoying little laptop charging reminder utility that does the job.

---

There are times when I'm deeply immersed in focused work, a meeting, or engaging video content and end up missing the usual low-battery notifications on my MacBook.

When the laptop suddenly shuts down, it's followed by the familiar and frustrating walk to find a charger or power outlet. It can be annoying and occasionally embarrassing, especially when rejoining a session a few minutes later with, "Sorry, my battery died."

Over the past few weekends, I built Plug-That-In, an app that introduces "floating/moving notifications". These alerts follow the cursor, providing a stronger, harder-to-miss nudge regardless of what’s happening on screen.

The app also includes a few critical features:

- Reminder Mode: When the battery reaches critical levels, the app emits a configurable alert similar to a car's seatbelt warning, continuing until the battery is addressed.

- Do Not Disturb Settings: Customize alerts and sounds based on context, such as when system audio is playing, a video is active, or the camera is in use.

It grew out of a personal need, and I'm glad to see it used by over 50 people in the past month.

Working on a flight tracking tool that records the landing and takeoff actions of a local airfield to get insights in how they determine on which runway a takeoff or landing is assigned. Problem is that all the free aircraft api's don't register a landing or takeoff act and also not on which runway.

The airport in question has just one runway and is situated in a dense population area. Both sides of the runway are used (officially noted as two runways) for takeoff and landing causing noise complaints in the neighborhood. The airfield says it assigns a runway based on wind direction and speed, and when there is much traffic they relieve one of the two directions to prevent going over a threshold. My goals is to check if they follow their own rules and just to have a insight if my annoyance over why there are so many aircraft over my house and not on the other side is justified or not.

As a frontender this is quite challenging. I'm using Express with typescript to write the backend. Usually I get bored quite quickly because progress is not going fast enough, so I'm using a lot of AI to speed things up.

I'm checking for aircraft in a 5km circle every 30 seconds. If a aircraft is below and above x feet than I'm going to track it every 5 seconds. Between each entry I'm checking the coordinates and altitude to determine which runway (direction) is used and if it's taking off or landing. I'm also using another API to get weather data like wind speed and wind direction. Finally this is saved in a JSON file (for now) and loaded into the frontend to be displayed in a table.

I do have a working prototype, and removing a few bugs. At the moment it's checking the logs after a day of collecting to check for errors, fixing those errors and validating the fix the next day. When it's done I'm planning to open source it so that anyone can use it if needed.

I've decided to take a break from working on Pirsch Analytics (pirsch.io) until next year and focus on some side projects instead:

1. Shifu (https://github.com/emvi/shifu) - a code-based CMS with admin UI. It's really easy to set up, written in Go, free and open-source, and I already sold a few websites using it. It can be used as kind of a framework to build more specialized features into a website and takes away the maintenance hell from managing a WordPress installation or a similiar CMS with tons of plugins that break with every update.

2. Zenko (working title, repo is private for now) - a very simple and no-bullshit project management software. It will be free and open-source, but I might offer a hosted option for a few bucks (like $20/year for all users of a team). I mainly build this for ourself to replace Linear, because we don't really make use of it. Don't get me wrong, Linear is awesome, but we basically only need an advanced Todo list. Main goals:

* Pull updates on the dashboard by yourself, instead of receiving notifications all the time via email

* Keep it simple stupid - no unnecessary features, no AI, just the bare minimum

* Cheap (for the hosted version, free if self-hosted) and easy to host (again written in Go)

* No feature-creep

3. Last but not least, I'm working on a "game engine" written in Go and SDL2. I do this for fun, but it is coming along nicely and teached me a few new concepts already (like ECS in Go).

On and off, I am currently coding a minimal wayland compositor for linux and AMD GPU(no libdrm), in RISC-V assembly (64bits), which I run on x86_64 with a small RISC-V machine code interpreter written itself in x86_64 assembly. I do not use ELF, but a file format (excrutiatingly simple as such file format type should be on modern hardware architectures) of my own with an ELF capsule (also written in x86_64 assembly).

I start with SHM memory, will add linux dma-buf once SHM is enough up and running. Currenty monothreaded, ofc. AMD GPU code for SHM is in, now writting wayland protocol code to please the first wayland clients I would like to run (not using the C libraries provided by the wayland project, native wire format).

I want to move away from x11, and once I get something decent with this compositor, I will probably have to fork xwayland in order to make it work with this minimal compositor, that for some level of legacy compatibility (steam client/some games).

In the end, I did design some kind of methodology and coded some SDK tools in order to write a bit more comfortably RISC-V machine code programs in a very simple fire format (only core ISA, not even compressed instructions, no pseudo instructions, using only a simple C preprocessor).

Coding time does not matter on such software in the light of their life cycle once it does "happen".

All that presuming not too much IRL interference... yeah, I know this is excessive to expect that...

The super hard part is not coding, it is motivation: energy, mood, cognitive bias, etc.

I've been working through advent of code using my own little compiler/language. It's in such an early state that some creative problem solving is required, not to mention the compiler bugs! But I'm very pleased to have it running interactively on my blog like this – I want to work towards some bigger notebooks in the style of explorable explanations.

Cool. What do you mean by 'manually' and 'some' delay?

If you have a list of posts you pull data from, it would be nice to have a simple clickable list of them all on a separate page. Also, (month year) could go next to neat 'View on HN' on each item.

I've been working (very slowly) on a cross-platform UI library written in C. It uses as much as it can from the OS without outright using the native widgets for everything. Rather the focus is on letting the user of the library customize the look of the controls as they see fit.

It's unfortunate but native UI (as in, using the native controls with their native look) has mostly died off in my opinion, at least for complex cross-platform applications.

You can try to do it in a cross-platform manner but it never works well. Want to implement a tab bar like VSCode's? Win32 tab bars do not support close buttons (need to be custom rendered) and Cocoa tabs it doesn't even make sense for them to have a close button. In Cocoa you're supposed to use either the windowing system to do tabs (similar to Safari tabs) or custom render everything (like iWork).

So I say screw it, make it look as you wish.

The design of the API is somewhat DOM inspired (everything is built up of divs that can be styled). It's pure retained mode for now, I still need to think how I'll make reactivity work.

On macOS it uses a custom NSView to implement "divs". Drawing is done with CoreAnimation layers. Text editing is handled by a nested a NSTextView control with a transparent background. Could also host a web view in a similar manner. Context menus are native.

On Windows it uses a custom C++ class that stores Windows.UI.Composition surfaces for drawing (could also use DirectComposition + Direct2D). Text editing is handled by a windowless RichEdit control (ITextHost/ITextServices). Context menus are native Win32.

On Linux it uses a custom QWidget with a nested QTextEdit control for text editing. I'm thinking of experimenting with Qt Quick for hardware accelerated rendering like the other two.

I'm building a web-based local multiplayer party game platform. It's like a lovechild of Jackbox Games and Mario Party: https://gamingcouch.com. We just won silver at the Big Indie Pitch competition as well!

- 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!

- In the future we plan to open up the platform for 3rd party developers (and Gamejams!) as well. We take care of the network connectivity, controllers etc.. 3rd party devs can focus on developing cool multiplayer mini-games without spending an eternity with networking code and building the infrastructure.

Interested to hear if this resonates with Hacker News readers!

Ono-Sendai2• 7 months ago

Neat idea. What is the controller latency like when using a mobile phone?

ChaosOp5• 7 months ago

The platform uses WebRTC for connections so in the best case scenario (direct peer-to-peer connection): somewhere between 2-10ms. When direct connection is not available, 20-100ms. In really bad network conditions with VPN's in use: 100-300ms. Though usually the latency is not really visible in the games even if there would be larger latency with some players :)

This is cool. It looks like it's possible for devs to add their own games, similar to Airconsole. What sets your platform apart?

ChaosOp5• 7 months ago

Thanks! Yes, or at least it will be in the future as we have not yet publicly released our SDK's for 3rd party devs :)

What sets us apart from AirConsole is our strict niche focus on real-time action party games and social couch gaming. In practice this means that the games added to our platform's public playlists should adhere to being short, competitive and real-time (no asynchronous or text/language-based trivia games).

AirConsole on the other hand is fully focused on in-car-entertainment at the moment as the whole company was recently sold to a car software manufacturer. My understanding is that they are not accepting any new 3rd party games on the platform apart from few very high-profile games based on already established studios and IP.

I'm working on a charitable donation tracker for taxpayers. My wife and I used Intuit's ItsDeductible for years until it shut down in October. With a little encouragement, I built Charity Record.

The stack is Django 5.2 (I know, I know, I'm looking at 6 now), Postgres, and HTMX + Alpine.js for interactivity. I'm using Polar for subscriptions. It's running on the $12/mo DigitalOcean droplet.

Trickiest parts so far: TXF export (we can trace TXF back to the 1990s...) and PDF generation. At one point when working on PDFs, WeasyPrint was deadlocking a single-worker setup because it fetched the logo via HTTP. (Base64-embedding the logo got me past that, ha.)

Had to read the wikipedia article on Real-Time Operating System (RTOS) to figure out what it was supposed to mean. https://en.wikipedia.org/wiki/Real-time_operating_system

They compare it to timeshare systems, which seems horribly out of date (although apparently that's still kind of what occurs anyways on CPUs). What's the part that's "Real Time" relative to anything else people do with Cortex processors? The preemptive part? Not trying to be critical, just not getting the real time part. Does it not share CPU resources among tasks? Get a fixed core per task or something? Minimal interrupts and minimal thread switching?

ab71e52• 7 months ago

An RTOS compared to bare metal just means it is some nice abstractions that you would expect from an OS : tasks, mutexes rtc.

An RTOS compared to an OS like linux basically just means it is deterministic, you can guarantee some interrupt is handled within a certain time. Not necessarily faster

raphui3• 7 months ago

As ab71e5 said, "Real time" in the context of OSes, means the operating system is optimized for determinism. The OS guarantees that events will be handle in a particular time-window and that high priority task will always run first.

I'm working on a no-code admin dashboard.

A small startup generally needs to explore and edit the production data. They would either build an admin dashboard, which is expensive, or use a database tool, which is bad for security. Not to mention a tool like pgadmin and dbeaver is clunky because they focus on database administration.

Backdoor is a self-hostable database querying and editing tool for teams. It reduces the need of an expensive admin dashboard. You can configure access control and validation policy for each user. The activities are tracked. It saves money and time, and it's more secure.

You can have your non-technical CEO, customer support, and sales to edit the production data in a safe and secure manner.

It currently supports Postgres and ClickHouse.

I'm working on finishing my JS KV compatibility library polystore [0], the goal is to make a widely compatible library to connect to many stores so that you can have a wide range of stores easily accesible.

For example, you make an API client library, now you can add polystore and accept multiple cache stores without writing all the compat layer yourself. This is a problem I've had multiple times in the past.

Or you make a project with cache, having it in files for local dev (highly debuggable) and then with Redis in prod is a simple ENV var change:

    let store;
    if (process.env.REDIS_URL) {
      store = kv(RedisClient(process.env.REDIS_URL).connect());
    } else {
      store = kv(`file://${process.cwd()}/cache/`);
    }

I've made many other libraries and projects during the years and having a single library handle all of this would be great.

properbrew21• 7 months ago

This is _very_ smooth and really well done. I've only played a bit of the Solitaire but it's really nice on both desktop and mobile.

I'm curious why you're rewriting it for a fourth time? Am I playing version 3 or 4 right now?

Two potential suggestions:

1. You save the game on pause / tab close, it means I'm not able to continue from another device. Would it be possible to provide some form of "seed" that I could input in my other device to continue where I left off? Not sure if that's even possible, just an idea.

2. Option to toggle between mobile/desktop style cards. I understand the desktop style ones might look a bit small on mobile, but I would prefer it.

Great work and site bookmarked.

https://sim.mycnc.app/ A CNC simulator that runs in the browser or as a PwA. I wrote this mostly for myself to compliment a g-code sender I am also working on https://mycnc.app/ . The simulator has some basic g-code and cut verification and analysis built in with more to come.

I am learning hobby CNC having come from the 3D printer world and I found that the CNC software is considerably more complex than today's 3D printer software.

CNC seems to be the next hobbyist maker boom with the likes of Makera and Nestworks having very successful Kickstarters.

https://plimsoll-line.app

I learned that ships have a "max load" line (or Plimsoll Line) https://en.wikipedia.org/wiki/Load_line_(watercraft) to prevent overloading them with cargos, but my todo list didn't. So I built an app to surface my emotional load and put mental health above raw productivity.

I am experimenting with the concept of giving each item in the iOS Reminders app an impact multiplier between -1.0 and +1.0 to assign them "weights". The net weight of the todo items should indicate my overall mood or emotional burden. If it doesn't maybe I have yet thought about what's making me feel good or bringing me down. The net weight is visually represented by the "water line" that rises the more into the negative the net weight becomes. I'm thinking of adding features to nudge me into addressing the rising water line.

And since I want to lower my own stress and anxiety using this app, there is no signup or subscription. No data collection other than the bare minimum to make the "tip jar" working through the App Store IAP, so no PII collection.

Do you think you'd find this approach to be helpful for managing your own anxiety level?

(Edited to add a bit more clarification)

factsperiodt• 7 months ago

Love the idea! I was thinking it would be great if it could include a toggle that's kind of like the emotional version of selecting reverse y-axis in games (i.e. you can either push the controller up to look up, or push the controller up to look down) - you can either have the app show you tasks as how you see them. You could either use a view that has the more effortful/urgent ones in red, which may grow over time the longer you take to do them OR the tasks that cause you more anxiety to have a high blue capacity the moment you plug in the task and it reduces over time the longer you take to get to it. I guess my idea has a factor of procrastination that comes into play with the anxiety.

tunaoftheland2• 7 months ago

Thank you so much for taking a look at Plimsoll Line and giving such a good feedback! The anxiety caused by procrastination is definitely real, my wife and I both feel the stress when we see our devices spew the same reminders that have been postponed for many days (or months!).

The main thing that I would like the app to do is to nudge me to take small actions of visually surfacing the emotional impact of the individual items (a todo item or just a thought in my head) rather than them filling up my head. So I would like to be the one driving the app than the app driving me like most todo apps do. I want the app to help me break myself out of being paralyzed with anxiety by taking small actions that are doable and maybe even pleasant. Hopefully that makes sense when users try it. :)

So I'll have to think hard about how to solve the problems you mentioned, they are excellent points. Having fewer configurations and encouraging the user to take control of their emotions through small actions as core principles means some limitations in features...

Anyway, right now the app lets you write a "Quick Journal" into the Notes field in the Reminders app. I have in mind the app encouraging user to break down the items causing lots of stress into sub-items so it becomes more manageable. Or suggesting contacting a trusted friend that the user has selected in configuration beforehand.

Suggestions welcome on how else I can nudge myself and other anxious users! :)

We have about 1600 books or so at home, there's no chance I'm going to scan ISBN codes of all of these. I've tried four times and got way too bored after the first 100-200. The solution? Take a photo of the bookshelf, send to Claude for text parsing and series information. Then some UI etc around that.

It's working, I just need to start testing it myself and a few friends have also asked for access.

Primary goal with the project was to create a Bluesky client that I wanted to to use.

With the transition to Liquid Glass, felt like a good time to practice and get to experience the new UI with a new project.

Still in what I call "alpha", but pretty feature rich. Support push notifications, lots of discovery/feed following features, search tools, moderation setting management, post translation, and much more.

If you use Bluesky and are an iOS user, there's still space on my TestFlight and would appreciate any feedback or comments!

I'm actually building this exact thing right now. Using Gemini TTS with its multi-speaker capabilities. Soundtrack comes from a Suno Playlist which the tool will download the entire playlist at the start.

Plays 3-5 songs prior to a "break", where the logic will call out channel donators vs pick a random topic to discuss, then use an LLM to generate the script before sending to gemini.

In the end; its really just a wrapper around FFMPEG broadcasting to an SRT or RTMP stream. I can upload the latest branch when I get home to share

I am pretty sure 90% of playlists you hear when out and about are generated by spotify algorithms at this point. I would more be concerned because it seems like a weird use for LLM when recommendation engines are probably better than it? I suppose it has a ton of training data around music forums and people recommending songs, but it is hard to believe that would beat out billions of hours of tracked listening spotify has access too.

At the same time, we want to keep a strong human balance in the process: hiring is a two-way street, and screening shouldn’t be fully offloaded to AI. We’re human-first.

https://meetlace.ai - LACE, a self-organising research companion for long-horizon inquiry.

With LLMs, generating ideas and snippets is cheap; what’s hard is keeping track of fragments with their “why I cared” context over months. Most tools (Notion/Obsidian/etc.) assume you will do the work (folder/tag/linking) structure will maintain it forever. I don’t.

In LACE we: – capture fragments from the web via a browser extension – auto-cluster them into evolving “threads” / projects with summaries & reading lists – maintain a graph of connections across threads (“topology of attention”) – let you turn a cluster of fragments into an essay draft when you’re ready to share.

Stack is a fairly standard web app + LLM pipeline. Used neo4j's llm-graph-builder as a starting point.

The interesting bit is self-organising graph. treating fragments/questions/lines of inquiry as first-class objects and letting the system reorganise around them over time instead of fixed folders.

It’s in a small test phase right now. If you’re a researcher/writer/engineer/founder who constantly loses good ideas in your notes and want to try something opinionated in this space, I’d love feedback.

ohmyai3• 7 months ago

Thanks! really appreciate it! Shortly: We're trying to turn LACE into a curiosity engine instead of another note graveyard.

Right now you can clip fragments from the web, LACE auto-organises them into evolving research threads, builds a concept graph + summaries, and lets you chat with your own library (find bridge connections, pull related papers, or turn a cluster into an essay draft).

Where we're going: more “emergent” behaviour – high-signal rabbit holes (papers, videos, posts) based on what you’re actually working on, plus light collaboration so people can share drafts and reading lists around a question. The idea is that LACE keeps organising and resurfacing things for you, on the right time, instead of you fighting with folders/tags in Obsidian/Notion.

If that sounds fun, I'd love it if you can give it a spin and give us feedback. I'm on https://x.com/oyayla_ - if you can DM me I can also invite you to our Telegram group.

We've been building https://nimstrata.com/ for almost three years now, we put Google's Vertex AI product discovery algorithms on Shopify and Salesforce ecommerce storefronts.

At a high level, Google does not have a product culture, so there is a lot of white space for companies like ours to make adopting Google Cloud APIs much easier for less technical users.

It's also wild how much Agentic AI is creeping into all of our conversations - this space is constantly evolving as we're building.

I'm working on ffl (https://github.com/nuwainfo/ffl), an Actually Portable Executable (APE) that turns any file or folder into a secure P2P HTTPS link via WebRTC.

Like llamafile, it's built on Cosmopolitan Libc. Getting the full Python stack + WebRTC to run as a single APE binary was incredibly tricky to pull off, but the result is super convenient. I mainly built it to solve the pain of moving large files (logs, DB dumps) in and out of containers—now it's just one command.

The repo has a demo showing a round-trip transfer between Windows (x64) and Android (arm64) using the same binary. I hope you give it a try!

I'm working on Mutacortechs, an ALife simulation where "organisms" each have their own emulated 16-bit processor with 64K RAM. Like Core Wars for the 21st century. It's a small project compared to what some others here are working on, but it's an order of magnitude larger than anything this embedded EE has ever written. I have the ISA designed, assembler complete, emulator stage 1 complete (160/204 instructions implemented), and the start of the simulation working. Last night I wrote a program in custom assembly for an "organism" that looked around, found food, moved toward it, and ate it. I'm pretty excited by the milestone!

A small tool that does one thing: publish Markdown and give you a link—no accounts, no setup, no project scaffolding. Paste or write Markdown, click Publish, and you get a human-readable URL you can share immediately. You can update or delete the page later using the same link.

The idea came from frustration with how oddly hard it still is to put a Markdown document on the web without turning it into a repo, a static site, or a login-gated doc. JotBird is editor-light but publishing-first, and I’m now exploring CLI and editor integrations so it can act as a simple publishing layer for tools people already use.

I'm working on EACL: http://github.com/theronic/eacl

EACL (Enterprise Access ControL) is a situated ReBAC authorization library based on SpiceDB, built in Clojure and backed by Datomic. EACL queries offer sub-millisecond query times and has replaced SpiceDB at work (CloudAfrica).

'Situated' here means that your permissions live _next_ to your data in Datomic, which avoids a network hop and avoids syncing to an external AuthZ system like SpiceDB, so all queries are fully consistent.

EACL is fast for typical workloads and is benchmarked against 800k permissioned entities. Once you need more scale or consistency semantics, you can sync your relationships from Datomic to SpiceDB 1-for-1 in near real-time because there is no impedance mismatch between EACL & SpiceDB.

Read the rationale for EACL here: https://eacl.dev/#why-was-eacl-built-the-problem-with-extern...

IMO, if you need fine-grained permissions, EACL is currently best-in-class for the Clojure ecosystem. EACL is especially suited to Electric Clojure applications and can be used to populate menus in real-time.

EACL would not have been possible to build solo in my spare time without modern AI models to rapidly implement specifications and test against human-written tests.

Here is a ~7-minute screen recording of EACL used from an Electric Clojure application for real-time ReBAC queries: https://x.com/PetrusTheron/status/1996344248925294773

It’s offline-first, supports importing text from anywhere, camera OCR, and a fast dictionary.

fsniper4• 7 months ago

For a headphone you do not even need the amp. The pcm5102a purple module can directly use headphones. Mine already has a 3.5 jack . It has been a life saver for devlopment at night.

I am planning to replace the amp with a Pam84xx and switch to a smaller/thinner speaker to save space. I may also add a nfc reader module to add nfc card music. Probably card will include a url to download music file.

Also my protoboard based solution is finicky. I starded building a pcb, however as this is my first pcb project I am taking it real slow.

Perhaps I can open a git repo to document share what I have.

working on bringing some basic, banal bits of infrastructure management to real-world traffic issues.

I'm literally trying to fix broken junctions around me.

It's at the same time laughably easy, and wildly complicated.

I'm calling the alternative, correct junction a 'traffic bean':

https://josh.works/traffic-bean

It's relevant to software, sorta. I've got rather a lot of GIS/mobility-related data available here. It's just a rails app that renders a bunch of my strava activity data all at once: https://josh.works/mobility-data

The fixes are entirely accomplishable with nothing more high-tech than traffic cones. They can be upgraded to more permanent and pretty physical objects, but the key bit of the traffic bean finds traffic cones fully sufficient. No half-million USD traffic signals, no red/green/yellow light cycles. continuous flow. safety. peace.

Some stuff that's obvious in some domains, like "at high-throughput times, don't allow key bits of infrastructure be completely unusable".

Bringing this to american municipalities is like trying to speak a language with someone that doesn't speak your language, but demands that you treat them as if they do.

it's been a big, long-running project. Most tradition in the USA is really a fig leaf for supremacy, and people can smell that I'm coming for their supremacy a mile away, and they immediately begin deploying emotional defenses.

I feel like I am constantly fighting LLM interfaces to make available and organized the context needed for discussion. There just seems to be way to much copy pasta into and out of the infinite scroll interface. I also find the output tough to quickly edit and discuss with the chatbot.

It is simple enough but I couldn't find anything like it and it has quickly become one of my favorite tools. I am build over buy to a a fault, so if there is something out there like this already I would not be surprised.

I've continued to work on an open-source containerized agent framework called Capsule Agents. Lots of progress this month and I have my first one live in my homelab! I'm training for a marathon and its able to send a discord message every morning with the workout on my schedule and the "why" behind it.

Here's the elevator pitch for the framework:

Its built around 3 key ideas I've dealt with inside the agent ecosystem 1. Agents become far more capable when they have access to a CLI and can create or reuse scripts, instead of relying solely on MCP.

2. Multi-agent setups are often overvalued as “expert personas” but they’re incredibly effective for managing context, A2A is the future.

3. Agents are useful for more than just writing code. They should be easy for non-engineers to create and capable of providing value in many domains beyond software development.

If that sounds interesting take a look! https://github.com/brycewcole/capsule-agents

I'm building out a new concept around training AI computer use agents on real sensitive tasks without PII exposure. My first demo releasing soon is a dataset of AI agent with human assisted tasks on things like paying my personal credit card or doing bank transfers.

Main things: 1. I don't modify the website I operate on 2. I take full videos and record all AI agent logs and all human actions 3. I don't modify any of those logs and will release them to the public.

I am working towards a future where AI companies are paid to generate the data they need for AI agent operations instead of paying massive sums to generate synthetic data. Imagine a future where labeling companies are completely sidestepped by simply training on production tasks directly.

Working on NetBox Designs: https://netboxlabs.com/blog/netbox-designs-introducing-decla...

Infrastructure architects think in terms of building blocks in "high-level designs" and those building blocks are often socialised/expressed in Visio/Spreadsheets. Thinking in building blocks is now more necessary than ever because of the sheer size of the infra being designed/deployed.

This approach is problematic after the design phase because there's a lossy translation to where the low-level design lives, often referred to as the Source of Truth, like NetBox.

NetBox Designs allows users to express composable, versioned, and templatizable building blocks that can be rendered to low level designs. No lossy translations, and you can always check in the future "does my LLD still match my HLD and if not, where?"

I'm working on a Unicode visualization tool [note 1]. It's meant to visualize transformations and relationships between characters, as well as connect everything directly to the exact lines in the Unicode Character Database (UCD), which defines these relationships. The UCD is a series of text files, it also has an XML version.

I love online Unicode tools, serious ones and silly ones, and I use them often for fun or for development. What I see online is that few technical people have a good understanding of Unicode, or have big misconceptions about how it works. I'd like to change that, through visualizations and direct links to the data sources (the aforementioned UCD) and links to the Unicode documentation (which is well-written but can be difficult to navigate or even find).

I've worked a lot on it, but I'm totally stuck again. I get too zoomed in and it's hard to see the big picture, plus it's difficult to know how much effort I can realistically put in because I don't know how big the market is. It's a niche tool, but how niche? Would anyone pay for it? But I'm not sure how to do market research, especially for a niche like this. Any advice would be appreciated!

We want to speed up adoption of custom AI, but most people suck at building it (no expertise, money, time, etc.).

We thought, what if you could "Vibe ML" your way to it? Allow any AI engineer or PM to build custom AI directly from their current implementation.

So we built these agents that orchestrate the entire life-cycle of custom AI. We start by hooking into how you use AI, prepare/label your data, detect the best recipes for your task, fine-tune, and deploy it for you. Really tried to simplify the entire process.

We aren't entirely sure about the UX/UI patterns. We aren't going chat first because if most people don't know where to start with ML, how in the world are they going to prompt it!?! Instead, we auto detect the AI tasks you've built and go from there.

I’m working on DeepCost.ai, an AI-driven cloud cost optimization tool for AWS, GCP, and Azure.

The goal is to help small teams and fast-growing startups understand where cloud spend is leaking and automatically reduce waste (idle resources, over-provisioned workloads, inefficient Kubernetes setups, and AI API usage). Setup is lightweight, and we focus on actionable recommendations rather than massive dashboards.

We’re still early and testing with a few teams who want better cost visibility without running a full FinOps practice.

I just moved to a house with a barely finished basement. White walls, white painted floor, exposed ceiling joists and ductwork painted black. I’m experimenting with cheap projectors and lighting effects (using clamps to attach to the joists as if they were a truss) and furniture on wheels to create a configurable virtual space with full wall projections, sound, and lighting to match (but not overpower) the video. My plan is to make a camera/light platform with a cheap projector, and Raspberry Pi, and directional LED lighting so that I can coordinate all of them over the network. It’s also my office, library, game room and I have some awesome ideas on how to use the space to augment D&D games. But the white concrete floor has got to go - too bright, too cold, too hard, and too loud.

Basically personalized meal planning and grocery integration. Since the Show HN I posted a couple months back I've been incorporating user feedback to add things like meal prepping, better ingredient reuse across meals, and cooking style preferences.

One of the biggest points of feedback has been adding more grocery stores but I'm really limited by who has APIs to actually integrate with, which is basically just Kroger and Instacart. Walmart has an API but ignored my API access request. Would love to hear if anyone has ideas on how to approach this.

It includes the usual uptime monitoring service that you see everywhere else, but also features such as a PageSpeed Insights monitor (https://securitybot.dev/pagespeed-insights) and a broken link checker (https://securitybot.dev/broken-link-checker). I continue adding new monitor types as I personally need them (and also based on use feedback).

I’m building something that keeps finding gaps I didn’t realize were gaps.

It’s called Riftur, a gap analysis tool that compares two documents and highlights gaps, missing requirements, and inconsistencies. The interesting part for us has been getting the system to understand intent instead of just keywords, so it can flag partial matches and subtle gaps rather than just “present / not present.”

Still early, but it’s been useful in ways we didn’t fully expect. If anyone’s curious, you can demo it out here: https://riftur.com I'm happy to hear thoughts or learn how others handle this kind of review work.

Something small that has been on my mind for the past decade or so -- assistant chatbot.

Basically I long wanted to plug a chatbot into my messenger of choice with all sorts of tools for quick use, of course after the emergence of LLMs it was only a matter of time before I find time for it.

As an experiment I have decided to use Claude code + opencode to develop it, and after some trial and error I am very thoroughly impressed with the results, it grew to a nearly 10k LOC in a week and it is still very much manageable, I haven't changed a single line of code manually still.

I have developed it as a "core" that imports modules with a rigid and thoroughly documented in a spec.MD file interface, and every single bit of functionality essentially acts as a different sub-app that can consume events that trigger it and handle all of the internal logic within itself, that way everything is separated nicely and totally manageable within LLM context.

It does everything from setting up and sending reminders and todo lists, helping me track car mileage and fuel consumption, getting an overview of the day ahead(sometimes if task is important even a reminder few days prior to its date), to even opening my front gate. And all of that is exposed to 'core' chat module through tool calls, so I can request anything in plain English or voice.

Also has a web-ui where I can review tasks, reminders, settings or search past conversations.

Been using it a lot, and since I'm using groq for inference, I still haven't even needed to pay a thing, since it fits within the free limits

Working on improving the data pipeline for https://iplocate.io - an IP intelligence service I've worked on since 2017. A couple of recent focuses:

1. VPN and proxy detection. We already track dozens of providers, but we can do better here. There's also a bunch of metadata we collect as part of this process which we don't currently surface, so I'm looking at what else we can bring to our databases and free API.

2. Better detail and evidence on how we build and test our own geolocation database, which we create from scratch. There's been a recent trend of misinformation about geo accuracy, including from some other providers, so I want to better explain the accuracy (and inaccuracy) of various techniques, our policy for when we prefer certain data, and so on.

(Open to partnerships for any folks looking for a new provider!)

A security-focused "check engine light" for your shell prompt: https://github.com/erichs/dashlights

There's a gap in most security tooling: it's not IN the terminal with you. It doesn't have enough context: your environment, your repo state, your current directory, etc. to catch the small hygiene mistakes that accumulate over the many tiny decisions you make every day to ship code and learn new tools. Those "cut corners" add up, and can lead to costly blunders.

Dashlights attempts to bring awareness and visibility to your immediate shell context.

In my free time this year I've been working on a full stack JS framework called Torpor: https://torpor.dev (https://github.com/andrewjk/torpor)

Components are JS functions, containing UI that is (mostly) HTML, with reactivity only via proxied objects.

To test it out I built a distributed social media/microblog site called Redraft: https://redraft.social (https://github.com/andrewjk/redraft)

It's edge native (with a Cloudflare deploy button in that repo) with your posts stored in an SQLite file. You can log in to your site to post and comment on your own posts, and use a web extension to comment on posts from people you follow wherever they are on the web.

There are many bugs and missing features, the documentation is patchy, and it's probably riddled with security holes. Give it a go if you're feeling brave!

This is actually pretty much as done as it's going to be (could use some nicer UI feedback, i.e. how you actually use the app) - it is actually just a demo for an effort I undertook to mod Datastar to support nested web components. I am writing it up as we speak!

Instructions: you have to answer three questions; each one will auto-submit once your response goes over 100 characters; the answer to the third question is your "post". It's a proof of concept of a friction intervention for social media to encourage slow thinking before posting (and hopefully reframing negative experiences in the mind, it's kind of dual purpose).

I’m working on a deterministic execution layer for AI systems.

The idea is to treat LLMs as constrained components inside explicitly defined workflows: strict input/output schemas, validated DAGs, clear failure modes, and replayable execution. Most “AI unreliability” I’ve seen isn’t model-related — it comes from ambiguous structure and hidden assumptions around the model.

We’re exploring this through a project called FACET, focused on making AI behavior testable, debuggable, and reproducible in the same way we expect from other parts of a system.

Still early, but the goal is simple: less magic, more contracts.

Still very early stages, just put the site together a few days ago: Veform https://veform.co/

iOS/JS/Android Libraries for turning traditional inputs/forms into audio conversations.

Have everything working and am happy with how the underlying data structures came out.

It is interesting because where I ultimately landed there is just an additional "state". So there is a UI state (Browser managed DOM), your app logic state (consumers manage), and a conversation state. The library just exposes events so you can keep the conversation state in sync with your other states. I started out visualizing a direct like: <form/> as a conversation flow, but you could configure it to navigate pages, click elements, or whatever through audio conversation.

Connecting the dots from agents to workflow automation to infrastructure with Taskade Genesis.

LLMs made it easy to generate apps. The harder problem is running them as real businesses. Where they live, remember state, coordinate agents, trigger workflows, and keep operating day to day. We treat the workspace itself as that layer.

One prompt becomes a living system. CRM, ops hub, internal tool, business in a box. Memory, agents, and automations working together. Feels closer to early web hosting than modern SaaS. Not demos. Real systems.

Still early, but builders are shipping real internal apps and workflows, not demos. Excited for the future of AI from productivity to agents and workflows to Infra!

I'm recreating Windows 98 desktop GUI faithfully in pure HTML, CSS, and JS, complete with desktop theming, file management, and some programs recreated from scratch or embedded from existing ports.

It started when I was feeling nostalgic and tried to redesign my website with retro style. Then I found 98.css and OS-GUI and got carried away and now it's a full fledged web OS.

There are some accurate recreation attempts like Minesweeper, Media Player and some screensavers, some with my own spin like ChatGPT-enhanced Clippy and Notepad with syntax-highlighting. I also include some well-known projects such as JSPaint, JS-DOS, and many Emscripten ports.

I'm aware that many retro Windows web recreation exist (98.js.org and poolsuite.net are my favorite), but none of them accurately captured the joy of desktop customization that I look for so I made my own version.

Been working on any-llm managed platform, a service for people using multiple LLM providers who want a safer way to manage API keys and track usage.

API keys are encrypted in your browser before they’re stored, so we never see plaintext keys. Usage tracking is limited to tokens and costs, no prompts or responses.

It integrates with any-llm and any-llm-gateway, so apps can fetch provider keys securely without hardcoding credentials.

It’s in alpha and still in its early stages, but already useful if you’re juggling OpenAI, Anthropic, Google, or local models.

ReQuoted is meant to make that part easier: build a quote from your phone, reuse materials/labor, send something clean, track, and revise without starting from scratch.

It’s intentionally lightweight — not an ERP, not trying to run the whole business.

an AI-native book reader that actually understands what you’re reading.

You highlight text, and the app infers intent and surfaces the right actions inline.

Examples:

Highlight a confusing paragraph → auto-suggests questions like “what does this term mean?” or “how does this relate to earlier chapters?”

Highlight a name → instant character context (no spoilers)

Highlight an argument → concise breakdown, assumptions, counterpoints

It works across EPUBs, PDFs, and papers, and the core rule is: AI should be assistive, never intrusive. No prompts required, no context switching.

I'm building a simulation training to master online self-defense.

I take the principles of martial art and apply it to online safety against all the current threats.

This is a browser-based simulation game where you train and learn detecting threats and dark patterns in a safe environment.

I've build it in Python/Flask as a solo maker.

Any suggestions are welcome!

I'm building Flock, a social goal tracking and intentions app. Styled a little around Complice/Intend, but with more of a focus on working in public with your friends and colleagues - see what they're working on, track your intentions against specific goals.

Building out reviews now - so you can systematically review your progress against your goals to stay on track. Give it a try, and add me as a friend! https://www.flockwith.me/u/henryaj

I’ve been working on a terminal-native AI coding tool called Aye Chat.

The idea is to remove the copy/paste/review loop entirely. Instead of asking an AI for code and then manually approving and applying it, the tool writes directly to files in your folder and automatically snapshots everything so you can diff or instantly undo if it gets something wrong.

It lives entirely in the terminal, so you can prompt the AI, run tests, open vim, refactor, restore changes, all in one flow. The bet is that with current models, the main bottleneck is the human, not LLM.

It’s open source and still very early, but we already have a steady cohort of users - as the flow is sticky after the "aha" moment. Repo is here if anyone’s curious, give it a star if you like the idea: https://github.com/acrotron/aye-chat

Happy to answer questions or hear skepticism :)

I am still working on my helpdesk. An easy to use self-hosted IT Helpdesk system for small IT teams. Vibe coding it with VSCode and CoPilot. I started this project when I needed my own helpdesk and didnt want to pay a fortune online providers. It runs on Python with Flask and Sqalchemy. It can be ran from the python files, or the executable is portable and can be ran from any windows computer. It stays in the network but I run with a ZeroTier connection so I can access it from anywhere without the risk of it being live on the internet.

Features I have implemented so far: Ticketing (duh), Email va MS Graph for MS office, Documents for info/repeat answers, Purchasing, Inventory, Projects -group of tickets)

New features I just added in the last month is Ticket Approvals if you need a managers approval for purchasing something or assigning a licenses to someone.

I don't have anything to show for it yet, but I'm rebuilding my dotfiles from scratch with a (hopefully) reusable framework that I want to open source some day. I don't know if it'll be useful to anyone else as I have very strong opinions about how this kind of stuff works, but hey, maybe someone else will find it useful. I'm inspired to do this because I realized the other day that computers....aren't fun for me anymore? So I'm taking the opportunity to make my computer mine again rather than continuing to rely on VSCode and all the automated config my company drops on our machines.

In other news, my first astrophotography rig is _finally_ mostly fully put together, and I'm going to try to go out and do some captures tomorrow night!

A WhatsApp store link.

Instead of sending products details one by one, you send your store link, your customers browse through your products, add to cart and the cart is sent directly to you.

Also works for those who have hit the 500 product limit on WhatsApp.

- Getting ready to start a slow migration of some services from unraid to an argo/k8s cluster (starting with some services I don't use yet which are hard to keepup in clickops, immich,peertube, etc)

I'd like at some point to try to make an android app for personal use, but my strong preference for lean toolchains and non-ide-based development are hindering me there. It doesn't help that I'm using nixos, and the toolchain for developing even with gradle and kotlin is a nightmare. I'm not sure when I'll have the patience to approach that issue again

- Working on my two papers about a new unifying theory of software architecture based on the "Independent Variation Principle" (IVP) (one paper for IEEE ICSA 2026 conf, Research track - I hope it will be accepted, and a long-form paper already on Zenodo: https://doi.org/10.5281/zenodo.17677316). - Today I have started vibe-coding a frontend framework called wickeTS based on Apache Wicket's concepts, but for TypeScript. According to an analysis I made of various frontend frameworks (Java, JavaScript, dotnet, php...) using the IVP, Apache Wicket is the one that presents the highest compliance level with the IVP (the best decoupling of constructs that have different change driver assignments). I'll use it for my website (a knowledge base) about the IVP, and if it works, also for other things. I'd say that for SSR, I'm at least halfway there after half a day. For CSR, I haven't tested yet. I also plan to support Static Site Generation. And I plan to support accessibility standards. - Organizing the creation of my company to start working as a freelance software consultant (mostly for archi & dev).

somethingsome• 7 months ago

Hey I see that you are in Belgium, do you have some introductory material on IVP? Or recorded seminars? I'm always interested in learning more about arch

humanfromearth92• 7 months ago

Hello

Introductory? just a few articles on dev.to. Link to one article, you'll find the others in my profile: https://dev.to/yannick555/novel-contributions-of-the-indepen...

You might want to read "Chapter 8. Applying IVP: A Practical Framework" of the long-form paper.

It's difficult to have introductory stuff right now, I've only recently started publishing about it, and I've been busy with the very formal ICSA paper.

Nevertheless, I plan to publish a web site which would serve as the knowledge base about IVP in a near future (few weeks time).

There's actually so much to say about it, and I'm having new ideas every day... Latest one: use IVP to compare open-source software with proprietary software under the lens of their change drivers in various contexts.

I'm trying to do a deep dive on RAG/LLM based apps since I didn't had the chance yet.

I'm building a chat-assistant that will be able to discuss with you and find more about what's your current work status and what you're looking for. Then it will suggest best suited roles for you from the HN Who's Hiring threads.

It's still very early, I've managed to index the latest thread and there's a CLI chat tool to discuss with the LLM.

It's been great because I learned a ton already, about LLM deployments, RAG evaluation, prompt engineering, LLM internals, etc.

Building an AI Hacker - https://aisafe.io

After years of manually reviewing thousands of lines of code, I realized the demand for security expertise is vastly outpacing the supply, and AI-generated code is only accelerating this gap.

I don't believe "generate secure code by default" is a problem we'll solve anytime soon, if ever. So I'm building an autonomous solution to help restore the balance.

Planning to launch very soon - keep an eye :)

StrataCreator• 7 months ago

I'm working on a Log analyzer, something that doesn't choke on huge files. I ended up building something that can open a 50GB log file in 8 seconds and not eat your RAM, while maintaining 60fps when scrolling.

All this with a native C++ engine (able to run on Windows, Linux and MacOS) with a Flutter UI.

With additional features that DevOps teams and SRE can use like Live SSH tailing, JSON analysis and formatting, context aware search with regex, text, and search via JSON fields. All those things also performing incredibly fast - analysing a 5GB file for JSON logs takes about 2s on my laptop.

Still in beta currently, with about 70% of the functionality done! You can find more here https://getstrata.co.uk/ :)

IntelliAvatar• 7 months ago

I'm experimenting with a local-first autonomous agent system on Windows.

The interesting part for me hasn't been the UI or demos, but the engineering problems: how planning compares to step-by-step tool-calling, how state drifts over long tasks, and how fragile things get once you add retries and recovery logic.

Mostly learning by breaking things and trying to make the system more predictable.

Intention is to make a free, local, and simple notetaking app for the iPad since Notability/Goodnotes seem to have become overly bloated, and then add optional AI features that are actually useful, and which stay out of the users way unless really needed.

launched v1 on the App Store about a week or so ago, currently have about 130 downloads and 2 users paying for the AI tier

I created a simple app that lets your kid call Santa AI via video call. Parents can use this webpage to schedule a 5-minute or 10-minute call with Santa, who will speak to their child.

Very, very realistic and could support a dialogue, ask questions, and even tell if there is a gift for a kid.

I use the HeyGen AI avatar, and I DO NOT record any video. Would you show this to your kid? Could you give me some feedback?

I'm going to add blind test, match mode, user track reorder. Very much a pet project, still rough around the edges. Feedback and feature ideas very welcome!

Back in 2020, while federating more than 100 service meshes across on-prem and AWS for a big hybrid cloud project, I had an idea: what if we could "split" the CAP theorem in a way that flips its limitations, enabling massive scaling far beyond traditional consensus protocols? Fast-forward five years:I started prototyping with libp2p, but the networking layer was always just a means to an end; the real goal is that CAP inversion/split for extreme distributed scaling. I think the timing is perfect given current geopolitical pushes.

Super curious to hear thoughts from folks. Any pitfalls I'm missing? Open to feedback or collaborators.

I'm working on Lumi AI (https://apps.shopify.com/lumi-ai-seo-alt-text), a Shopify app that automates product content generation (descriptions, SEO titles, meta tags, and alt text).

The main problem we're tackling is the quality of automated content for large catalogs. Instead of just spinning existing keywords, we use Vision AI to analyze product images directly. This allows us to generate accurate, accessible alt text and detailed descriptions based on what the product actually looks like.

To avoid the "generic AI" feel, the app also crawls your existing store content to build a custom brand voice profile, ensuring new content matches your established tone.

Key features: • Vision-based generation: Analyzes images for context-aware descriptions and alt text (WCAG 2.1 AA compliant). • Brand Voice Intelligence: Learns from your previous writing style. • Bulk Processing: Handles up to 500 products per batch with real-time tracking.

We have a free tier (20 credits/month) if you want to give it a spin. I'd love to hear your feedback on the "Vision AI" output quality versus standard text-generation tools!
