Last year PlasticList discovered that 86% of food products they tested contain plastic chemicals—including 100% of baby food tested. The EU just lowered their "safe" BPA limit by 20,000x. Meanwhile, the FDA allows levels 100x higher than what Europe considers safe.

This seemed like a solvable problem.

Laboratory.love lets you crowdfund independent testing of specific products you actually buy. Think Consumer Reports meets Kickstarter, but focused on detecting endocrine disruptors in your yogurt, your kid's snacks, whatever you're curious about.

Here's how it works: Find a product (or suggest one), contribute to its testing fund, get detailed lab results when testing completes. If a product doesn't reach its funding goal within 365 days, automatic refund. All results are published openly. Laboratory.love uses the same methodology as PlasticList.org, which found plastic chemicals in everything from prenatal vitamins to ice cream. But instead of researchers choosing what to test, you do.

The bigger picture: Companies respond to market pressure. Transparency creates that pressure. When consumers have data, supply chains get cleaner.

Technical details: Laboratory.love works with ISO 17025-accredited labs, test three samples from different production lots, detect chemicals down to parts per billion. The testing protocol is public.

You can browse products, add your own, or just follow specific items you're curious about: https://laboratory.love

I'm building Mochi, a small programming language with a custom VM and a focus on querying structured data (CSV, JSON, and eventually graph) in a unified and lightweight way.

It started as an experiment in writing LINQ-style queries over real datasets and grew into a full language with:

- declarative queries built into the language

- a register-based VM designed for analysis and optimization

- an intermediate representation with liveness analysis, constant folding, and dead code elimination

- static type inference, inline tests, and golden snapshot support

Example:

  type Person {
    name: string
    age: int
  }

  let people = load "people.yaml" as Person

  let adults = from p in people
             where p.age >= 18
             select { name: p.name, age: p.age }

  for a in adults {
    print(a.name, "is", a.age)
  }

  save adults to "adults.json"

Happy to chat if you're into VMs, query engines, or DSLs.

Strongly recommend the rust remover described by Backyard Ballistics[0] on his second channel[1]; 1 liter water, 100g citric acid, 40g washing soda, generous squirt of dish soap. He claims the acid and alkali cancel out so there's nothing to attack the normal metal surface, but they leave citrate ions which dissolve rust by chelation, which makes it better than just citric acid, vinegar, or soda alone, which all pit and dissolve the clean metal surfaces, and easier/better than wire wool scratching. He also claims it's as effective as EvapoRust but much cheaper and can do more rust dissolving per litre than EvapoRust.

- The encoder ring which works like an LED mouse, but in reverse: Fully reverse-engineered and on its own demo PCB

- The faceplate PCB, which does the actual control of the thermostat wires, has been laid out, but the first version missed a really-obvious problem involving the behavior on power-on with certain of the GPIO pins from the ESP32, so I've got rev 3 on order from the PCB manufacturer.

Nest Thermostats of the 1st and 2nd generation will no longer be supported by Google starting October 25, 2025. You will still be able to access temperature, mode, schedules, and settings directly on the thermostat – and existing schedules should continue to work uninterrupted. However, these thermostats will no longer receive software or security updates, will not have any Nest app or Home app controls, and Google will end support for other connected features like Home/Away Assist. It has been pretty-badly supported in Home Assistant for over a year anyway, missing important connected features.

My film got screened at the Academy Award-qualifying Bali International Film Festival and the Marina Del Rey Film Festival in the past month. It will be screening next month in New York City at the Asian American International Film Festival.

I also wrote a metaprogramming language which generates a lot of the editor UI for the engine. It's a bespoke C parser that supports a small subset of C++, which is exposed to the user through a 'scripting-like' language you embed directly in your source files. I wrote it as a replacement for C++ templates and in my completely unbiased opinion it is WAY better.

From a dev perspective this area has a ton of super interesting algorithmic / math / data structure applications, and computational geometry has always been special to me. It's a lot of fun to work on.

If anyone here is interested in this as a user, I'd love for any feedback or comments, here or you can email me directly: tyler@vexlio.com.

Some pages the HN crowd might be interested in:

The standard fiscal POS app was adapted to support a sort of low-trust swarm of waiters who used the app to collect orders. These orders were then transferred to a few high-trust cashiers by scanning QR codes generated on the waiters' apps.

After receiving payments, the cashiers' apps printed invoices and multiple "order tickets" categorized by "food," "drinks", "sweets"... This allowed waiters to retrieve items and deliver them to customers.

The system was used by around 40 users, with new waiters joining or leaving throughout the event. They used their own phones, and the app functioned without internet or Wi-Fi, gracefully downgraded (If a waiter didn't use the app due by choice or due to technical problems, they could manually relay orders to cashiers), Customers also had the option to approach cashiers directly, receive their order tickets, and pick up items themselves.

This is not that technically interesting, but I liked how the old manual system, the 70+ year village firefighting org. main cashier had, got digitalized in non-centralized way. (and I took this chance in trying to explain it, as I will have to, to maybe find more users for it)

* OSINT (r00m101 just beat me to it by launching...)

* Research into recommendation algorithms, advertising placement algorithms, etc

* Marketing (ad libraries, detailed analysis of content given data not even exposed to the mobile app due to some interesting side channels, things like trend analysis, etc)

* Market research for products

* Sales teams can use it to find exact mentions of other products. Eg: selling crash reporting software? Look up your target accounts' brands and find examples of complaints.

Plus a few more with more imagination.

So I'm working on a site that allows user access to some of the read-only functions available here. Coming soon :tm:. Been really fun building it all in Rust, though :) If you're interested in anything here, email in profile.

I've gotten the process to fully catalog all of the advertisements in a magazine (about 150 on average) down from over a week to a few hours. I should be able to get through the material within my lifetime now :)

Autonomous robotics for sustainable agriculture. Based in the south of the UK. Prototypes of an autonomous mechanical farm-scale weeding robot currently beginning real-world testing. Still a huge amount of work to do though.

Hardware and software developed fairly much from scratch, not using ROS (for not entirely crazy reasons...); everything written in Rust which I find well suited to this application area.

The robot is built using off-the-shelf components and 3d-printed custom parts, so build cost is surprisingly low, and iterations are fast (well, for hardware dev).

On robot compute is a couple of Raspberry Pi 5s.

Currently using the RPi AI Kit for image recognition, ie Hailo 8[L] accelerators.

Not currently using any advanced robotics VLA-type AI models, but soon looking to experiment with some of it, initially in simulation.

Feel free to get in touch if you'd like to talk :) Contact details in my HN profile, and on our website.

- LegalJoe: AI-powered contract reviews for startups, at the "tech demo" phase right now: https://www.legaljoe.ai/

- ClipMommy: A macOS tool to help (professionals who record a lot of videos | influencers) organize their raw video clips. Simply drag a folder of "disorganized" videos onto ClipMommy, and ClipMommy organizes the videos into folders / subfolders, adding tags, based upon some special statements that you can make at either the start or the end of your video (think audio-based "clapboard"). I'm expecting to release this within a week or two on the Mac App Store (Apple allowing...).

As an aside, I've been very impressed with Claude Code, it's (for me at least!) leading the way for how the next generation of business software might leverage AI. I plan to iterate on LegalJoe to make more "agentic" as a result of what I've seen is possible in Claude Code.

* Expect/snapshot testing library for F# is now seeing prod use but could do with more features: https://github.com/Smaug123/WoofWare.Expect

* A deterministic .NET runtime (https://github.com/Smaug123/WoofWare.PawPrint); been steaming towards `Console.WriteLine("Hello, world!")` for months, but good lord is that method complicated

* My F# source generators (https://github.com/Smaug123/WoofWare.Myriad) contain among other things a rather janky Swagger 2.0 REST client generator, but I'm currently writing a fully-compliant OpenAPI 3.0 version; it takes a .json file determining the spec, and outputs an `IMyApiClient` (or whatever) with one method per endpoint.

* Next-gen F# source generator framework (https://github.com/Smaug123/WoofWare.Whippet) is currently on the back burner; Myriad has more warts than I would like, and I think it's possible to write something much more powerful.

This week, I'll set up a Hugo blog with the Ed theme, love it, looks exactly what I'm looking for, and as a former LaTeX enthusiast, it's pretty close. It's readable, minimalist. I'll need to customize the theme, though. I plan to publish blog posts about anything I find interesting.

https://gohugo-theme-ed.netlify.app/

In parallel to this work, I'm setting up a simple system to keep my website + subdomains easy to build, rebuild, and deploy with Caddy on a cheap Scaleway compute server. In the past, I had some ideas I wanted to publish, but the system I went with made managing the sites dreadful.

Once that's ready, I'm back to learning Rust and crypto. It's fun, interesting, challenging, remote-friendly, and the salaries are usually 30-50% better. My current tech stack feels like a dead end: it has a low ceiling in terms of salary, the projects are generally not very interesting (I'm grateful for my current project, it's the best there is with this technology), and I believe the technology will see a slow and steady decline.

Apart from work, I'm building the playground for my 2 yo son, and planting blueberries, he loves them.

The goal is to transcribe and provide summaries, topics, notable quotes, and companies and people discussed.

Feel free to send more ideas!

Folks have reached out about having an 'In Loving Memory Of' site for their loved ones, so I'm turning this into a side business to help out more with my (now widowed) father's retirement and care.

The main use-cases I'm thinking of right now is triggering agents using email or a very simple document upload flow to any SaaS (just forward an email to the SaaS).

Brief backstory: While visiting us overseas, my in-laws were in a very bad car accident. Everyone involved is alive and going to be okay. But what followed was a series of emotional, physical and logistical challenges that pushed my wife and her parents to their limits.

During this time I found myself (shamefully) hiding on my phone. I was obsessively refreshing for updates from insurance/hospital teams, sending empty messages, and mindlessly scrolling feeds. My screen time was averaging 12 hours a day. Time I could have spent being fully present with my wife and her parents.

I finally accepted I have a serious phone addiction. I tried Apple Screen Time and a few popular screen time management apps, but found the blocks were too easy to bypass, and some apps were as useful as they were distracting depending on the context (e.g. YouTube). I didn’t necessarily want to use my phone less: it’s an incredibly useful tool, and the distractions were sometimes helpful.

What I really needed was intentional stretches of time spent away from my phone. I built touchgrass.fm as a simple way to record and incentivize those stretches of time. It’s not quite finished, but it’s been helping me stay present for hospital visits, meals and important conversations.

Been working on this for a while, with the aim of making something simple and immediately usable. Components are JS functions, containing UI that is (mostly) HTML, with reactivity only done through proxied objects.

To test it out I built a distributed social media/microblog site called Redraft: https://redraft.social (https://github.com/andrewjk/redraft)

Self-hostable or hosted for a fee, all your posts stored in an SQLite file, comment/like/react on other people's Redraft posts via a Web extension (pending approval, but you can use the unpacked version from source).

Both are in a pretty rough state, but usable for the intrepid.

Handles everything from real-time driver tracking, public order tracking links, finding suitable drivers for orders, batch push notifications for automatic order assignment, etc.

Backend: Feathers.JS, Postgres + TimescaleDB & PostGIS, BullMQ, Valhalla (for multi-stop route optimization although most of our deliveries are on-demand)

Frontend: SvelteKit

Mobile App (Android only for now): React Native/Expo, Zustand, Expo push notifications, and two custom native modules for secure token storage and efficient real-time GPS tracking. The tracking was probably the toughest to get right to find the best balance between battery/data efficiency and more frequent updates.

Been testing it for a couple weeks and as of last week, that company moved their operations over to it with 50+ drivers and thousands of orders processed through it so far (in a country with pretty unreliable connectivity/infrastructure).

I built it initially as a favor but open to other applications for it.

I recently impulse bought an Epson receipt printer, and I’ve started putting together a server in Go to print a morning update every day. Getting it to print the weather, my calendar and todos, news headlines, HN front page. Basically everything I pick up my phone for in the morning, to be on paper rather than looking at a screen first thing. Very early days but hacking away and learning escpos/go! (Vibecoding a lot of it)

Two months ago I posted an update that I had begun work on my Chrome extension [1] for Relevant. Relevant is a crowdsourcing website where users can categorize the channels they watch into a defined hierarchy of categories ranging from broad topics like "Science" and "Gaming" to more specific ones like "Phone Reviews" or "Speedrunning".

Although I had a little bit of engagement on the website, I found myself looking for something that could bring the experience onto YouTube, so I began work on a Chrome extension. It turns out there's a lot more complexity in building a Chrome extension than I realised. It's basically like building a website for the popup window, a javascript server for the background service workers and a message bus for the service worker.

After 2 months' of working weekends, I finally released a version of it that lets users see the categories of the content on the page, discover more channels matching those categories and contribute to the categorisation effort!

Long-term, passion project of mine - I'm hoping to make this the best typing platform. Just launched the MVP last month.

The core idea of the app is focusing on using natural text. I don't think typing random words (like what some other apps do) is the most effective way to improve typing.

We offer many text topics to type (trivia, literature, etc) where you type text snippets. We offer drills (to help you nail down certain key sequences). We also offer:

- Real-time visual hand/keyboard guides (helps you to not look down at keyboard) - Extremely detailed stats on bigrams, trigrams, per-finger performance, etc. - SmartPractice mode using LLMs to create personalized exercises - Topic-based practice (coding, literature, etc.)

I started this out of passion for typing. I went from 40wpm to ~120wpm (wrote about it here if you're interested: https://www.typequicker.com/blog/learn-touch-typing) and it completely changed my perspective and career trajectory. I became a better programmer and writer because I no longer had to think about the keyboard, nor look down at it.

Currently, we're doing a lot of analysis work on character frequencies and using that to constantly improve the SmartPractice feature. Also, exploring various LLM output testing/observability tools to improve the text generation features.

Approaching this project with a freemium model (have paid AI powered features; using AI to generate text that targets user weakpoints) while everything else in the app is completely free. No ads, no trackers, etc. (Hoping to have sufficient paid users so that we can run the site and never have to even think about running ads).

I've received a lot of feedback and am always looking for ways to improve the site.

But, I'm determined to see its completion even if there is just one user. I didn't take the Wordpress fiasco and how they handled it, lightly at all and it only fueled my motivation even more. ETA is by end of this year right on time for Christmas.

If you'd like to read more, here's an article about my CMS: https://medium.com/creativefoundry/what-i-learned-as-an-arti...

After HashiCorp was acquired by IBM I decided to take time off from corporate life and build something for myself. For years I've also been a casual retail investor on the side.

Forums like /r/stocks and /r/wsb in the past have been useful resources for finding leads and interesting information. But meme-ification (among other factors) have substantially degraded sites like Reddit, to the point where interesting comments are much fewer and far in between. With TickerFeed I'm hoping to recapture what was lost - a platform where investors can discuss companies and all things stock market through meaningful long form content.

It's also a chance to build something with my dream stack - Go + HTMX + SQLite, and that's been fun :)

In Singapore, the system is heavily academic. You're expected to follow a rigid path (PSLE → JC → Uni → job), but no one teaches you how to think about what kind of life you want to live—or how to create it. That leaves many people feeling lost, even if they’re “on track.”

This platform flips that. It starts with the big picture: *“When you’re 90, what do you want your life to have looked like?”*

From there, users create a personal timeline of milestones across life domains: health, relationships, learning, impact—and now, *financial freedom.*

The app helps users:

1. Set long-term visions, then break them into clear, visual milestones

2. Use an AI assistant to suggest weekly actions and recalibrate as life evolves

3. Voice journal instead of typing; the AI transcribes and flags patterns (“You mentioned burnout 5x this week. Want to add a rest week or revise your work goals?”)

4. Track basic finances and align spending/saving to long-term goals (“You want to take a year off at 30. At this pace, you’ll have the runway by 32. Want to adjust?”)

5. Get matched with mentors or peer circles for guidance and accountability

The goal is not to “optimize” life like a spreadsheet. It’s to help people reflect, take control, and become someone they’re proud of.

If you’ve worked on anything in this space—journaling, goal tracking, financial wellness, coaching—I’d love to learn:

A. What made your tool stick long-term?

B. How did you balance simplicity with depth?

C. Any design or product traps I should avoid?

Appreciate any thoughts, questions, or brutal feedback.

Obviously the main thing is getting the listings data, which as far as I know (mostly) isn't readily available any other way that scraping the cinemas' websites, for which I set this up as a separate-ish project[1]

Building cables for multiple personal and professional projects, I was frustrated by having to cobble together harness diagrams in Illustrator or Visio, cut snippets from from PDFs for connector outlines, map pin-outs, wire specs, cable constructions, mating terminals, and manually updating an Excel BOM.

Splice gives you:

An SVG canvas to drag-and-drop any connector or cable from your library to quickly route and bundle wires. Assign signal names to wires or cable cores.

Complete part data Connector outlines, pin-outs, terminal selections (by connector family & AWG), cable core colors & strand counts, wire AWG/color.

Automated BOM & exports parts-ready diagrams, wiring drawings, and a clean BOM in SVG, PNG, or PDF.

Connector & Cable Creators. Connectors or cables not in the existing library can be added with an optional outline and full specs (manufacturer, MPN, series, pitch, positions, IP-rating, operating temp, etc.), then publish privately or share publicly.

The site itself isn't anything "special." I've had a personal website for about 25 years; the past few years I finally moved from making HTML by hand to using various CMSes. I tried a "no database" CMS that my hosting page had, then I wrote my own CMS, https://github.com/GWBasic/z3, to learn node.js, but then I had to go back because Heroku dropped the free tier.

Jekyll is interesting. As a Mac user, I'm surprised there isn't a push-button app, like MAMP, to just run it. Instead, I got exposed to some weirdness with Ruby versioning that, because I don't have any Ruby experience, was frustrating.

The default Jekyll template has warnings, but when I tried to fix them, I ended up jumping into a rabbit hole of sass versioning.

I also ended up jumping into a rabbit hole with setting up redirects from old urls on my blog to their new locations. I don't touch Apache / cpanel that often, so there was a bit of a learning curve for me.

One funny thing was that I set up two redirects, in cpanel, from the same url to two different urls. (It was a mistake!) I couldn't delete them, so I had to submit a service request with my host.

Two interesting things that I do not have time to do:

- Set up Github actions to deploy on my original host (andrewrondeau.com) - Set up redirects from blog.andrewrondeau.com -> andrewrondeau.com

It's a web-based notepad calculator, which means it's a notes app but it can evaluate inline calculations like

``` £300 in USD + 20%

09:00 to 18:30 - 45 minutes ```

I wrote the core of the calculator a few years ago, and I've just launched a big rewrite that supports

* document syncing * offline editing * markdown formatting * PDF and HTML exports * autocomplete * vim mode

Happy to hear feedback :)

I do plan on open sourcing more of the code over time. I also have started working on other sites using the same algorithm implementation (music, movies, video games)

This has just been a side project over the year generating passive income. I get around 250,000 page views a day, and with ads, memberships, and affiliate links I make around $2,500~ a month.

Tech stack is ruby on rails 8, postgresql 17, opensearch, redis, bootstrap 5.3 hosting on 3 servers on linode.

Main focus is https://wheretodrink.beer, collecting and cataloging craft beer venues from around the world. No ambition of being exhaustive, but aiming for a curated and substantial list. After the last thread, a bunch of people added their suggestions, thanks! It helped add interesting new venues from cities I hadn’t covered yet.

I’m very slowly layering on features, and have a few spin-off ideas I’ll keep brewing on for later. The hardest problem thus far has been attempting to automate popularity rankings and automatic removal of defunct venues without breaching a bunch of ToS.

Also made https://drnk.beer, a small side project offering beer-related linkpages and @handles for Bluesky (AT Protocol). It's been on the backburner, but still very much live.

Probably looking for another small project for the next few months to focus on something else for a while. Always curious to see what others are building and doing. Thanks for sharing!

After a lot of grief trying to make Plex and jellyfish to work with my collection, and then some more with the community [1] I decided to make my own.

There's no selling point and clear pathway to monetize, as other solutions are way more mature and feature complete, but this is my own and serves my needs the best.

I've been working on it on and off for last 8 years or so, and it's been my personal benchmark for js ecosystem. The way it works, every now and then I come back to the project, look at the latest trends in js world and ask myself a simple question - what should I change in the codebase to make it online with the latest trends. And everytime it leads to full rewrite. Kind of funny, kind of sad.

In a nutshell I have a huge movie collection - basically I'm preparing for armageddon where all online streaming services cease to exist and I need both backend to fetch me detailed information about movies in the collection as well as frontend to help to decide what to watch tonight.

My next major endeavor will be trying to integrate RAG to take a bite at my holy grail - being able to ask a question like "get me a good gangster flick" and get reasonable recommendations.

[1] I think it was jellyfish where I was asking on their forums for how to manually create a collection, stating I'm a software engineer with 20+ exp and they kept telling me that I shouldn't touch the code... While having an online campaign asking for volunteers to contribute to the codebase.

For my 3D audio project I need an affordable way to make plastic cases. I felt like injection molding services are way overpriced, so I decided to make the molds in-house. Turns out, CNC milling is overpriced, too. As are 5 axis CNC mills. So in the end, we built our own CNC machine.

And like these things always go, I found an EMI issue with my power supply and a USB compliance bug in the off-the-shelf stepper control board. But it all turned out OK in the end so we now have the first mold tool that was designed and machined fully in-house. And I learned so much about tool paths and drill bits. Plus it feels like now that everyone has experienced hands-on how stuff is milled, my team got a lot better at designing things for cheap manufacturing.

When you post a listing (e.g., on Facebook, Kijiji), you get tons of “Is this still available?” messages — but no useful info. TenantFit lets landlords collect basic answers (income range, pets, lifestyle) via a public link, then ranks responses to highlight promising leads.

No accounts or sensitive info collected from tenants (landlord does not even see candidate email until they reply), just a quick pre-screen before deeper screening to save time.

I love books like this one. Some other examples are "Crafting interpreters", "Writing a C compiler", "Building a debugger", and a couple other lower quality ones. The potential in this space for aspiring technical writers is enormous. Let me know if you know some other books that guide you through implementing complex systems software from scratch.

- Migrating to Niri on my laptop and re-evaluating my literate config approach, switching from xkb configs to kanata and a few other QOL changes to make my tooling more composable and expressive

- Shoring up my blog / media sharing infrastructure (migrated to a landing page on an s3 bucket, with different prefixes for several different hugo deployments for different purposes, still need to get better about actually posting content)

- Preparing to migrate a bunch of my self-hosted services to a k8s cluster which can can be fully deployed locally for testing and defined in code. All this is managed through argo and testable with localstack and crossplane for some non-local resources

- Attempting (somewhat unsuccessfully) to setup a nixos config for a bunch of services that just don't feel right to run in containerized stack that I want to live in ec2 and have as close to 100% uptime as possible (uptime kuma, soju/weechat relay/bitlbee, conduit, radicale, agate, whatever else I think of that is small and has a built-in nixOS service module. Thinking about some kind of RSS aggregating solution here as well)

- Experimenting with vibecoding by trying to get an LLM to do the legwork to build a TUI interface to ynab using rust (which I don't know how to write)

I'm hoping that by the end of this summer most of the tooling I use for most things will be way more concrete and seamless. I also want to get my workflows down and get on top of converting at least a few the ~100 draft blog posts I have laying around into something I can actually post. Ditto for my photography albums, which are not yet organized into coherent groupings or exported for web.

I started on a Zig one and nope'd right on out of that after a few hours of fighting the compiler.

I'm currently working on porting a bunch of my Rust mini-games to other languages. [3]

An AI-native DocuSign

It's been around a month I've been working on it. Struggling with getting people to actually use it - this week I've set the ambitious goal of 10 new contracts sent *and completed* by people I don't know (last week's was 10...by people I do know).

It's hard because I feel I'm in a weird hole - in order to have a good product I need people to use it and give me feedback, but in order for people to use it and give me feedback I need a good product. It's like wth!

Another thing I'm struggling with - enjoying the process. I get daydreams like mad. I feel I'm always living in the future in some way, especially with this software, and it's taking away from being present in this work. Which sucks, because I want to be excited to *work* on this and NOT fake my own excitement towards this as a manifestation of my greed to get rich off it.

But MAN am I greedy. It's ugly sometimes, to myself.

But god how I love to work on software also. How I love making stupid bash commands on my terminal. How I love to feel like the old gods, who conquered the infant digital world.

Since TP 3.0 does no optimisations, and looking at the progress so far (~25% decompiled), it seems like matching decompilation should be achievable.

If/when I get to 100%, I hope to make the process of annotating the result (Func13_var_2_2 is hardly an informative variable name) into a community project.

My day job required me to go into office frequently, and I'm really feeling the reduced social connection of being fully remote in a small company. Any suggestions how to deal with this? I'm planning to reconnect with old friends, surf a lot, go rock climbing, and maybe take dance / music / other classes. Would also love if anyone wants to work together in the same place (library, coffee shop, etc). I'm in Escondido California, but happy to drive ~30 min to meet folks.

Local-first web applications with a compiled backend – After eight years working on web platforms, the conventional stack feels bloated. The client already defines what it wants to fetch or insert. Usually through queries. So why not parse those queries and generate the backend automatically (or at least, the parts that can be)?

Triple stores as a core abstraction – I’ve been thinking about using a triple-based model instead of traditional in-memory data structures, especially in local-first apps. Facts could power both state and logic, and make syncing a lot simpler.

Lower-level systems programming – I’ve mostly worked in high-level languages, but lately I’ve been writing C libraries (like hash maps) and built a minimal 32-bit bare-metal RISC-V OS.

It’s all still brewing, but I think these ideas tie together nicely. What if the OS didn’t have a file system and just a fact store? Everything could be queried and updated live, like a Lisp machine but built on facts.

Some other things I’ve been playing with:

A jQuery-like framework and element factory - You can pass signals that automatically updates the DOM.

A Datomic-like database on top of OPFS - where queries become signals that react to new triples as they enter the system. Pairs well with the framework above.

* https://trosko.hr (HR, Android/iOS app) - super-simple receipt/bill tracker (snap a photo of the receipt, reads it using Gemini, categorizes and stores locally - no accounts, no data gathering)

* https://github.com/senko/think (open source) - Python client library for LLMs (multiple providers, RAG, etc). I dislike the usual suspects (LangChain, LLamaIndex) but also don't want to tie myself to a specific provider, so chugging on my on lib for this.

I am experimenting with the current SOTA multimodal LLMs, but performance is still not yet there, they still hallucinate non-existent teeth. (As an aside, I have found a simple but very telling test, I have an image with only 4 teeth visible up and 10 down, so I prompt the modal to count, non have been able to, but Gemini 2.5 pro is the closest of the lot, performance is worse in the description when the counting test fails).

I am going to try segmenting the image to see if I will have better results by prompting to describe segment by segment.

To highlight the syntax in the browser I checked out the CodeMirror project that uses Lezer grammars. It is very flexible and allowed me to implement additional features like custom folding. [2]

I would also like to create a grammar for tree-sitter, finish the Java implementation and documentation of the ESON parser before I try to implement it in other languages.

Beyond the landing page (built with Astro), I've been building all of the route optimization, the delivery and warehouse management systems. A combination of go and java has allowed me to write a few microservices in the past 6 months to handle all of my logistical processes, and I'm just testing the mobile app in the field as we speak! I hope to make some of the code open-source one day!

https://axonmesh.pages.dev/

Right now I'm making an Anki-style flashcard system in Rust (https://github.com/jmahmood/Cardbrick/). It's amazing that all of the annoying stoppers I've had with build systems were blown away by Gemini. It's also nice to actually build something that is not another web application.

(I say this knowing there is zero value in me posting this in a thread with 1134 comments already)

My 7 year-old has gotten into music and is trying to record his own ideas. We have found the existing tools to be either too simple (Yak Back) or way too complex (Tascam). I want to make him something that has a simple interface, few buttons, and simple recording/mixing. The idea is to avoid the software programs like Garage Band and Logic.

First we built it as a tool to fix any bug. After talking to a few folks, we realized that it is too broad. From my own personal experience, we realized how messy it is within organizations to address accessibility issues. Everybody scrambles around last minute. No body loves the work - developers, PMs, TPMs etc. And often external contractors or auditors are involved.

Now with Workback, we are hoping to solve the issues using the agentic loop.

If you personally experienced this problem, would love to chat and learn from your experience.

I'm planning on doing a proper writeup/release of this soon, but here's the short version: https://gist.github.com/samscott89/e819dcd35e387f99eb7ede156...

- Uses lldb's Python scripting extensions to register commands, and handle memory access. Talks to the Rust process over TCP.

- Supports pretty printing for custom structs + types from standard library (including Vec + HashMap).

- Some simple expression handling, like field access, array indexing, and map lookups.

- Can locate + call methods from binary.

- The idea: https://carlnewton.github.io/posts/location-based-social-net...

- A build update and plan: https://carlnewton.github.io/posts/building-habitat/

Turn any command into an AI-discoverable MCP tool with a few lines of YAML:

   name: hello-world
   description: "Greets the world"  
   command: "echo 'Hello, World"

The insight: Most security scanners find problems but don't fix them. Industry average time to fix critical vulnerabilities is 65+ days. We generate the actual fixes and create PRs automatically, including educational content on the nature of the vulnerability and the fix in the PR description.

Technical approach: - AST-based pattern matching (moved from regex, dropped false positives from 40% to <5%) - Multi-model AI for fix generation (Claude, GPT-4, local models) - ~170 patterns across 8 languages + framework-specific patterns; can grow this easily but need more customer validation first.

Business model experiment: Success-based pricing - only charge when fixes get merged ($15/PR at the moment). No upfront costs. This forces us to generate production-quality fixes & hopefully reduces friction for onboarding.

Early observation: Slopsquatting (AI hallucinating package names that hackers pre-register) is becoming a real attack vector. It's pretty straightforward to nail and has a lot of telltales. Building detection & mitigation for that now.

I release code into the public domain hoping it will be useful. There's some fast code for Groebner basis computations using the F4 algorithm (parallelized - article to follow), and some routines for machine integers e.g. discrete logarithm, factoring, and prime counting.

Lets you create encrypted containers disguised as normal files. 1000s of images, pdfs, videos, secrets, keys all stuffed into an innocent look "Vacation_Summer_2024.mp4".

I've almost got true steganography working i.e to get the carrier file to actually open in any file system(currently with mp4, pdf, png and jpeg).

Things like this have existed in the past, but nothing with a simple UI,recent encryption standards.

While apps like Parkopedia and SpotAngels tackle the same problem, their one-size-fits-all approach often results in incomplete, missing, or outdated data. My approach is different: go deep on one city at a time by combining multiple publicly available datasets. This doesn't scale horizontally since each city has different data sources and formats, but the goal is to become the definitive parking resource for one city, build automation to keep it current, then methodically expand city by city.

If you are based in Vancouver, do give it a go. Your feedback would be awesome!

It's been a fun ride co-coding with Claude (Sonnet 3.5 > 3.7 > Code). Already it found a bunch of interesting bugs on a heap of my own sites, older employer sites, friend's sites.

Started as a simple Django web app, extended to Celery+Redis, now also leveraging CF Workers and R2 storage.

Was bourne out of an observation that some sites I have been working on missed some crucial things like domain expiration of asset-domains, mis-configured CORS or SSL certificates, http header and meta collisions, missing/wrong redirects for http/https/www/no-www etc.

This is written entirely in 6502 assembly, and uses a fun new mapper that helps a little bit with the music, so I can have extra channels you can actually hear on an unmodded system. It's been really fun to push the hardware in unusual ways.

Currently the first Zone of the game is rather polished, and I'm doing a big giant pixel art drawing push to produce new enemies, items, and level artwork to fill out the remainder of the game. It's coming along slowly, but steadily. I'm trying to have it in "trailer ready" / "demo" state by the end of this calendar year. Just this weekend I added new chest types and the classic Mimic enemy to spice things up.

An iOS client for Cloudflare. Surprisingly, there’s none out there, maybe because nobody needs it? I do, so I’ve created one and it’s now available on TestFlight [0].

Another interesting thing I’ve recently discovered is that LLMs are pretty great at vetting tenancy agreements, so I’m working on a website that reads tenancy agreements and will return a list of unfair clauses that might be present in the contract along with a detailed explanation of how you should follow up with the landlord/agency. I still need to finish it but if you’re interested it’s here [1].

To abstract around register file differences in different ISAs, I'm using SSA-form with spilling to a separate "safe stack". Enforces code-pointer integrity for security's sake (not unlike WASM) but extended also to virtual method tables.

"Partial-ISA migration" allows a program to run on multiple cores with slightly different ISA extensions. "Build-migration" is migration to another build of the same program in the same address space: Instead of trying to debug an optimised program, you would migrate it to a "debug-build" to attach a debugger. Or you could run a profiling build, compile a new build using the result and then migrate the running program to the optimised build: something that previously only JIT-compilers have done AFAIK.

I'm out of the research stage and at the stage of writing the first iteration of the main passes of the compiler, but now and then I've had to back-track and reread a paper on a compiler algorithm or refine the spec. It has taken a few years, and I expect it to take a few years more.

We're also working on the Premed Super App, same thing for people taking medical school entry exams like the MCAT or MDCAT.

Automating Clean-room plant propagation using robots

There are about 2-3+ Billion plants cloned in laboratory conditions per year which are all done by hand. I am in the process of trying to develop a MVP to automate this task while also getting customer conversations to get early adopters.

What I am struggling with is that I don't know if I should focus on developing the MVP which will cost 20k-40k & 4-6 months to develop or put in place a pilot program to get customers willing to buy the machine / pay up front before I start developing. Hardware startups are rough usually because their MVP takes so long to develop.

I am currently bootstrapping while I am pushing for more conversations trying to do both at once. I could personally finance the venture, but it seems like a poor move to just take on all the risk personally? I have am setting up conversations with a few VCs, but that is a month out.

I'm working on this full time at the moment. I have a couple people who I have talked to who could be co-founders but nothing has materialized yet. So I am just all over the place at this stage in the process.

I spoke to 4-5 potential customers and 2-3 of which are 'interested' in what I have but seem only interested in the 'validation' stage which only comes up after the huge personal investment on my end.

While Cursor stops after writing great code, Vide goes the extra mile and has full runtime integration. Vide will go the extra mile & make sure the UI looks on point, works on all screen configurations and behaves correctly. It does this by being deeply integrated into Flutters tooling, it's able to take screenshot/ place widgets on a Figma-like canvas and even interact with everything in an isolated and reproducible environment.

I currently have a web version of the IDE live but I'm going to launch a full native desktop IDE very soon.

The library of public domain classics is courtesy of Standard Ebooks. I publish a book every Saturday, and refine the EPUB parser and styler whenever they choke on a book. I’m currently putting the finishing touches to endnote rendering (pop-up or margin notes depending on screen width) so that next Saturday’s publication of “The Federalist Papers” does justice to the punctilious Publius.

Another Moby-Dick of mine is Kadessh, the SSH server plugin of Caddy, formerly known as caddy-ssh. This one is an itch. I wrote about it here https://www.caffeinatedwonders.com/2022/03/28/new-ssh-server..., and the repo is here: https://github.com/kadeessh/kadeessh. Similar to the other one, feedback and helping hands are sorely needed.

They are both sort of an obsession and itches of mine, but between dayjob and school, I barely have a chance to have the clear mind to give them the attention they require.

Trying to document and map as much of the publicly accessible stained glass as possible. The goal being the next time you visit a new city or town, you'll know where all the beautiful stained glass is to go see. Just recently added support for countries outside of North America. No exciting tech (vanilla HTML/CSS/JS). But excited for folks to check it out!

It's grown over a dozen or so years and when I finally decide to compile into a book, everyone now uses AI and no longer read and learn from books but instead through LLMs.

This is for people who feel powerless in light of all the recent political developments, and would like to do something positive to help.

My goal is to aggregate all the various ways you can actually do something to help, so you can find them without having to get on a million mailing lists.

I've been thinking a lot about the current field of AI research and wondering if we're asking the right questions? I've watched some videos from Yann LeCun where he highlights some of the key limitations of current approaches, but I haven't seen anyone discussing or specifying all major key pieces that are believed to be currently missing. In general I feel like there's tons of events and presentations about AI-related topics but the questions are disappointingly shallow / entry-level. So you have all these major key figures repeating the same basic talking points over and over to different audiences. Where is the deeper content? Are all the interesting conversations just happening behind closed doors inside of companies and research centers?

Recently I was watching a presentation from John Carmack where he talks about what Keen is up to, but I was a bit frustrated with where he finished. One of the key insights he mentions is that we need to be training models in real-time environments that operate independently from the agent, and the agent needs to be able to adapt. It seems like some of the work that he's doing is operating at too low of an abstraction level or that it's missing some key component for the model to reflect on what it's doing, but then there's no exploration of what that thing might be. Although maybe a presentation is the wrong place for this kind of question.

I keep thinking that we're formulating a lot of incoherent questions or failing to clearly state what key questions we are looking to answer, across multiple domains and socially.

I am using cerebras for book translations and verb extraction and all LLM related tasks. For TTS I am using cartesia. I have played around with Elevenlabs and they have slightly natural sounding TTS but their pricing is too steep for this project. Books would cost a couple of hundred euros to process.

Basic goals:

- Web based for zero update latency

- Have it work offline

- Automatically import transactions from my banks

- No running/hosting cost

- Secure

Tools used so far:

- InstantDB for the datastore, providing the offline capability too

- A gmail account that automatically gets forwarded bank alerts for purchases

- Gitlab.com w/scehduled pipelines for cron based email-syncing

- Netlify for the free hosting

- InstantDB magic codes / email links for securing the data

I'm at the point where I can track and categorize purchases, including split transactions.

Next steps:

- Add in date ranges for reporting / data views; e.g. show expenses incurred in a one month period instead of for all time.

- Add in planned / project transactions for month forecasting

- Statement import & import reconciliation and statement reconciliation

- Scrape company specific digital reciept emails (like Amazon) to autopopulate more transaction data

And that'll be the end of the stuff I can do for free. I think I will add features that require money and/or dedicated hardware though:

- OCRing receipts -> autopopulated transaction data / description

- Using chatgpt to suggest categorizations

- Scrape extra data from my bank sites, like physical addresses of entities involved in charges.

That's why I am building Overcentric - a simple and affordable toolkit that combines web & product analytics, session replays, error reporting, chat support and help center - all in one place.

Been building it and testing with several startups and improving based on their feedback. I am also using Overcentric for Overcentric itself, so I always get ideas for improvement.

What's next: more tools that are useful for startups are on the roadmap and I am exploring how LLMs can be further utilised (apart from support, session replay summaries, aiding in writing help center articles) and refining pricing.

Check it out at https://overcentric.com/

Would love to connect with other SaaS founders and have Overcentric help them grow their startups.

Tail calls between different VM functions are the next challenge. I'm going to somehow have it allocate the VM instance in the same space (if the frame size of the target is larger than the source, "alloca" the difference). The arguments have to be smuggled somehow while we are reinitializing the frame in-place.

I might have a prefix instruction called tail which immediately precedes a call, apply, gcall or gapply. The vm dispatch loop will terminate when it encounters tail similarly to the end instructions. The caller will notice that a tail instruction had been executed, and then precipitate into the tail call logic which will interpret the prefixed instruction in a special way. The calling instruction has to pull out the argument values from whatever registers it refers to. They have to survive the in-place execution somehow.

Why? I don’t like Discourse and Flarum that much. I want an even simpler solution with fewer bells and whistles.

But I guess the market is dead anyways for forums. I might replace my phpBB instance that has been running for 15 years.

Most employee engagement software is just placation for HR. When it's common that the lowest scoring question on feedback cycles is "I believe that action will be taken based on the results of this feedback," there's something fundamentally broken with how companies handle feedback, and how the tools their given enable them to react to it.

Our end goal is to help leaders and managers identify problems with trust and communication within a team. The reality is, 90% of the time, the problem lies with the leadership itself. We're trying to provide both the tools to diagnose what the problems are, and frameworks for managers to fix them.

More specifically, I'm trying to use pitch (F0) to dynamically adjust the theta parameter in rotary positional embeddings, so the frequency of the positional encoding reflects the underlying pitch contour of the speech and instead of using a fixed unit circle (radius=1.0) for complex rotations, I'm trying to work out how to use variable radii derived from the pitch. The idea is to create acoustically-weighted positional encodings, where the position reflects the acoustic salience in the original audio. https://github.com/sine2pi/asr_model

This is something I’ve needed myself over the last few years as jobs become shorter and shorter lived. Keep on improving it as some kind of compulsion.

We aggregated half a dozen plus disparate data sources to create a comprehensive infrastructure map of the PNW power grid. Our goal is to be able to query for and provide informed answers for grid operators, investors, and other energy adjacent businesses in the space.

(For reference): The PNW has the most abundant clean power in the US and is one of the markets with most opportunity as our consumption increases with AI.

Some examples:

- A minimal C shell with built-ins like cd, pwd, type: https://gist.github.com/rrampage/5046b60ca2d040bcffb49ee38e8...

- Terminal Snake game which fits in a QR code using Linux syscalls for drawing: https://gist.github.com/rrampage/2a781662645dc2fcba45784eb58...

1) Highly Sybil resistant. Neither the keypair owner nor anyone else can re-use the same underlying ID to link to another keypair.

2) Very high anonymity. While the Sybil resistance requires a nullifier representing the underlying ID to be present in a database (or stored in a public, decentralized form for blockchain use), there is no way to connect that nullifier with the keypair. Even if someone were to use brute force to successfully connect the nullifier with a specific underlying ID, such as a passport, there is no way to connect that ID with the keypair. (In the passport case, even merely brute-forcing the nullifier could only be done by the issuing government, someone who has hacked the government database, or someone with physical access to the passport. This is due to the fact that other passport information than the passport number is included in generating the underlying zero-knowledge proof.)

I understand that other technologies may have similar end-functionality, but this has the advantage that most of the functionality is encapsulated in a single Rust executable that could be easily used in any context, whether distributed or decentralized. (If anyone would like to know more, my contact info is at garyrobinson.net.)

My next item is to add AbuseIPDB IP addresses to my "Uninvited Activity"[1] IP address blocking system, implementing xRuffKez's script here: https://github.com/xRuffKez/AbuseIPDB-to-Blackhole

Unfortunately, but also understandably, AbuseIPDB limit their free-access (account required) API to 10,000 IP address records. So I might be putting it into a database to hopefully aggregate multiples of the 10k results if they're not always the same 10k.

The idea came from noticing how most people manage money day to day: checking their balance, adjusting by feel, trying not to drift. There are tons of tools for planning or categorising, but not much that fits that kind of improvised pacing.

Still early, but trying to shape it around those habits – to make something simple and steady, that supports how people already do things.

It helps you track, understand, and plan your personal finances — with a proper accounting foundation.

It's interesting in many way. Using double-entry (it's a perspective shift), the technical challenges of building local-first app, UI/UX & visualizations, privacy and more.

A multi-server process supervisor. Existing init processes (systemd, runit, s6, etc) work great on a single server but when you need to manage/deploy many servers, the tooling gets really complicated (K8s). Phoenix extends the process supervision model from one server, to many. Run this thing once / keep one copy of this around / keep this running on all machines that match pattern X etc.

Turns out the (obvious in hindsight?) problem is automated but simple networking. Currently digging deep into wireguard based overlay networking before rolling the next version of Phoenix out.

One interesting lesson is to see the effort involved in acquiring new customers and setting up funnels, especially when bootstrapping with a small budget. Sometimes, as developers, we are in our bubbles and don't realize how much skill one needs to figure out the customer acquisition domain.

It's an environment for open-ended learning with LLMs. Something like a personalized, generative Wikipedia. Has generated courses, documents, exams and flashcards.

Each document links to more documents, which are all stored in a graph you grow over time.

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

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

My credit rating has literally plummeted 200 points for reasons I don't even have the energy to investigate (I have a pretty good retirement fund, no debts/mortgage/care payments). Just no energy to do anything except hang around trying not to eat.

— it turns ebooks, articles, and documents into synchronized audio with real-time text highlighting. It’s great for people who prefer listening while reading (or want to stay focused), and it works fully offline with a one-time purchase — no subscriptions.

I’m bootstrapping it and trying to figure out how to market it effectively. So far, I’ve had some traction and early sales just by posting on Reddit, but I’m still learning the marketing side — especially how to reach people who’d benefit from it most.

Would love to hear how others approached early growth for similar bootstrapped tools.

I need to put it up on the ol' blog-thing, but I've signed a contract with a small press for a debut novel, which is highly exciting. That one's urban fantasy from the point of view of the wizard's magic cloak. (You better believe it has opinions.)

Meanwhile, I've been working on a novel about a group of time travelers who accidentally get stuck in the Permian, well before the dinosaurs. Surprise! There are still big animals that can eat you, they're just more weird (and not as big). The research for that one has been wild.

The ol' blog thing, where I post story-related tidbits and such: https://rznicolet.com

I want to publish it on Google play, but I need testers. If anyone cares about budgeting, I'd love to get some feedback.

I don't think you can download it without being added to my testers list though. Send me your Gmail address if you're interested!

These monthly HN threads have been great motivation for me to keep building consistently. Thanks everyone!

A dynamic runtime on top of the eBPF virtual machine / SQL workbench that lets you create real time visualizations of system performance data.

We built it because managing cloud budgets often turns into a spreadsheet mess, or worse, a never-ending consulting engagement. OneBliq lets you:

* Split and allocate Azure costs by cost centers, teams, or projects

* Visualize current spend and attention areas at a glance

* Experiment with plans and projections without complex tooling

* Skip sales calls and long onboarding – just install and kick the tires

It's still early, but we're seeing traction with teams who want clarity without complexity. Happy to answer questions, share more, or get feedback.

Would love your thoughts – what would make a tool like this useful (or useless) for you?

To that end, I've most recently been hacking on Robert Virding's Luerl (https://github.com/rvirding/luerl), working to adapt the Lua test suite to chase down some small compatibility issues between PUC Lua and Luerl. While Lua is a lovely language, it would also be swell to get Fennel working under Luerl. I wrote a game for the LÖVE jam a few months ago in Fennel and it was a pleasant way to dip my toes into lisp-likes.

I've also been adding things to control plane software, Overworld, here and there: https://github.com/saltysystems/overworld Happily all of the Protobuf and ENet stuff that I've already built nicely carries over into the LÖVE world.

I build an iOS app (https://quenchai.app) that uses a carefully constructed Multimodal LLM workflow to convert photos to standard drinks and track consumption over time.

Did you know a standard margarita is ~2.5 standard drinks and a light beer is ~0.8?

I'm trying to see if I can "get away with it": no schema migration, no fixed views, one tenant per DB, local-first-friendliness.

The general approach is "Datomic meets XTDB meets redplanetlabs/Rama meets Local First". Conceptually, the lynchpin "WORLD FACTs" table looks like this:

A workshop I've been experimenting with, using willing friends as guinea pigs. To help people remove friction from being able to "spool brain to disk". The sales-y part is here, with more context / explanation about what it is about and what it is not about: https://www.evalapply.org/index.html#writing-for-nerds

It's tested only on Android 10 and Windows 11. Bring done with Flutter, it should work on iPhone, Mac and Linux too but would need building, testing and fixing various issues found.

Had I known this would take me 3.5 weeks (dedicated time) and 6100 lines of code (including comments), I would not have done it. Ideal would have been just a week.

Currently closed source.

The goal is quite simple, allow developers to host their application with easy straight forward pricing. We are about to launch very soon. Everything is built on Laravel/PHP.

We are open to beta testers, so if you feel you want to test this please drop me and email in my profile.

1. After hearing Cell by Pannotia, I became obsessed with trying my hand at making a bit of electronic music. I have an Arturia Keystep 32, a Korg NTS-1 and a Korg SQD-1 to mess around with, but I'd really love to learn how to capture the sound on the Pannotia's album since it speaks to me on a visceral level (album link for the curious: https://pannotia.bandcamp.com/album/cell)

2. Turning some old telephones into fun "audio guestbooks", have some additional features lined up that I am going to add (just waiting on parts to arrive), trying to improve a bit on the ones shown in this excellent video: https://www.youtube.com/watch?v=dI6ielrP1SE

3. Managed to get a blog post up recently. My work is not exactly what I would call "HN worthy" but if you need a laugh or some decent toilet reading, it probably qualifies (my blog: https://futz.tech/)

I love these threads. So many people working on so many different and interesting things. Renews my hope for the future, a bit.

There's a little inspiration from the MLIR ecosystem here, which makes heavy use of `.td` files for code generation. I want to write a schema file, defining some tables and indexes along with the queries and procedures which will operate on them, then have this compiled to a C++ header file I can include, where the schema is a class and the queries/procs are methods.

I have no idea how far I'll get with this, but it's always fun messing about with weird little languages, and I'd like to see what programming in this style would feel like.

I've been working on making it easy to drop in socket-based multiplayer with "channels". Players can join channels and they can share messages, state updates or notifications over a socket connection. You can use it for chat rooms, lobbies/matchmaking or async multiplayer.

One recent addition is "channel storage": a shared space for players to read/write/update/delete data. This opens up saving and loading shared worlds between players in just a few lines of code.

Everything is open source, including the frontend dashboard, backend, Godot plugin and Unity package. GitHub here: https://github.com/TaloDev.

Reading through the Terms of service in websites is a pain. Most of the users skip reading that and click accept. The risk is that they enter into a legally binding contract with a corporation without any idea what they are getting themselves into.

How it started: I read news about Disney blocking a wrongful death lawsuit, since the victim agreed to a arbitration clause when they signed up for a disney+ trial.

I started looking into available options for services that can mitigate this and found the amazing https://tosdr.org/en project.

That project relies on the work of volunteers who have been diligently reading the TOS and providing information in understandable terms.

Light bulb moment: LLM's are good at reading and summarizing text. Why not use LLMs for the same. That's when I started building tosreview.org. I am also sending it for the bolt.new hackathon.

Existing features: Input for user entered URLs or text Translation available for 30+ languages.

Planned features: Chrome/firefox extension Structured extraction of key information ( arbitration enforced , jurisdiction enforced etc).

Let me know if you have any feedback

A bit of background: I have been working on a Raga classifier since November of last year - I started with just 2 ragas and a couple megabytes of audio. After experimenting with a lot of different ideas and Neural Net Architectures, I finally landed on one that could scale. I increases to 4 ragas, then 12, then 25 and then to 65.

All the training is done locally on my desktop (RTX4080, AMD 7950X, 64G RAM). My goal is to make an app for fast inferencing (preferably CPU) and to get this app in the hands of enthusiasts so that I can get some real data on its efficacy. If that goal is hit, then my plan is to iterate and keep increasing the raga count on the model and eventually release to the public. As long as I can get the model to either run locally or for very cheap on server, I hope to not charge for this.

It has been an amazing learning experience. The first time I got a carnatic singer to sing and the model nailed almost all ragas was the highest high I've felt in a while.

It currently supports subscribing, publishing, and unsubscribing in JMS, MQTT5, Redis, and Websockets, and send-only in SNS.

I'm not really sure who might use it, but it's been fun.

I did a screenshare demo of it yesterday: https://www.youtube.com/watch?v=GQzDfrdf71Y

Also, every region has different ways of representing a “neighbourhood”, so I get to learn how to extract viable data from each city. Lots of map stuff, I’m genuinely enjoying it!

It's written in elixir using Phoenix live views. There's almost no custom Javascript outside of what that framework gives. First load may take a while because it's the cheapest tier of fly.io and boot loads all known ingredients and products in to memory.

I've had some breakthroughs with LLM translation, and I can now translate (slowly, unfortunately) at a far far higher quality than Opus, and well above DeepL. So I'm considering offering that as an API, though I don't know how much people actually care about translation quality.

DeepL's customers clearly don't care - their website is all about enterprise features, and they appear to get plenty of business despite their core product being mediocre.

Would people here be interested in that?

Still thinking of how, what and when to open source.

We're building Redactsure.com

A novel technology whose goal is to separate data from interactions entirely. We are building a custom OS whose first goal is to detect, hide, and then use sensitive data throughout any web interface.

Building a new browser rendering layer with real time transformer inferencing is hard but it's been an amazing tech to work on. Long term we think this technology will change the way all remote work is done at a fundamental level.

So, I embarked a couple of weeks ago on my journey to build a relational database, which checks the boxes for me personally and I hope that this will be useful for other developers as well.

Project priorities (very early stage): - run code where the data is - inside of the database with user defined functions (most likely directly rust and wasm) - frontend to directly query the database without the risk of injection attacks (no rest, graphql, orms, models and all the boilerplate in between) - can be embedded into the application or runs as a standalone server - I hope this to be the killer feature to enable full integrations tests in milliseconds - imperative query language, which puts the developer back in control. Instead of thinking in terms of relational algebra, its centered around the idea of transforming a dataframe

Or in other words, I want to enable single developers or small teams to move fast, by giving them an opensource embeddable relational firebase.

If you have any thoughts on that, I would love to talk to you.

Aside from that, I’ve also made some sillier little games/demos[3].

There’s a computer with a classic BASIC interpreter written in Lua after the first level.

I got the demo video produced, and a blog set up and seeded. You can see some of the science behind learning multiple languages at https://phrasing.app/blog/multiple-languages or follow my progress using Phrasing to learn 18+ languages at https://phrasing.app/blog/language-log-000

Now I’m working on the onboarding process, which I’m very excited about on both a product and a technical level. On the product level, it dovetails nicely into most of the shortcomings of the app. One solution to a dozen problems.

On the technical level, I’m starting to migrate away from reagent (ClojureScript react wrapper). The first step was adapting preact/signals-react to support r/atom, r/cursor, and r/reaction. This has worked beautifully so far and the whole module, with helpers, is less than 100 LoC. I’m irrationally excited about it, and every time I use any method it brings me a stupid amount of joy… especially since it’s exactly the same API as reagent.

For those curious, the next steps in the migration will be: upgrading to React 19 support once reagent ships with it (in alpha currently), then replacing the leaf components with hsx and working my way up the tree. No real code changes, just a lot of testing needed. Maybe at the end of it all, I can switch the whole app over to preact — will be interesting to test the performance differences.

As far as ideas I’m thinking about, I’m currently planning the next task in my head. This will be an (internal) clojure library that will hopefully have ClojErl (erlang), ClojureScript (js), and jank (C) interfaces, which means I’ll be able to write clojure once, and run on the server, browser, and mobile — all in their native environment. Needless to say, being able to write isomorphic clojure without running JavaScript everywhere has me almost as excited as my signals wrapper :D

My wife (who is a psychotherapist) started this and I am helping her with this. We are using specially curated children's books as a medium to talk about social, emotional and psychological aspects of mental health among adults, adolescents and teachers. We are also building communities and support groupsaround children's books.

This is in India where talking about mental health can often be a taboo subject. People who need/want to talk about this also find it hard to express and there are limited spaces which give you opportunities to do so. We found the abstractness of children's books as a great evocative medium. They also promote play, wonder and joy - aspects which positively impact mental health of individuals.

The project started with a personal journey of grief my wife experienced (death of a parent, diagnosis of other parent with Stage 4 cancer).

I started by trying to reimplement the METAFONT language, adding support for real-time rendering with OpenGL. Eventually, I decided to introduce some incompatible changes, creating a new language. But it still retains a syntax and internal logic very similar to METAFONT.

This new language also supports animation, and since it is part of a larger project (a game engine), it can be used not only for font rendering but also to generate textures and sprites for games.

The language is successfully compiling to WebAssembly, and I’m currently working on a web page with tutorials, documentation and examples where you can modify the code and instantly see the results. Since this is a literate programming project, there is also an English and Portuguese version of the code. But the english version still needs considerable polishing.

Spent 14 years slogging through a custom implementation with my previous company, and didn't want my pain and suffering to go to waste. Just spent a few hours yesterday to replace that app's integration with my new api and got a pretty good diff:

You upload interviews with family members (text, audio or video all work) and the system automatically transcribes the text, finds key people or events, and puts it together with other information you may have gathered about those events or people before. Like building a genealogical tree but with the actual details about people's lives.

In the works to also attach pictures of said people and events to give it some life.

Crystal is a re-imagining of what an IDE means when AI drives development. Traditional IDEs are designed for deep focus on one task at a time, but that falls apart when you have to wait 10-20 minutes for an agentic task to run. Crystal lets you manage multiple instances of Claude Code so you can inspect/test the results of one while waiting for the others to finish.

The premise is that when I read social spaces like Reddit or X, if the government has done anything contentious you get nothing more than strident left takes, or strident right takes on the topic. Neither of which is informative or helpful.

So I have set up a site which uses AI which is specifically guided to be neutral and non-partisan, to analyses the government actions from the source documents. It then gives a summary, expected effect, benefits and disadvantages, and ranks the action against 19 "things people care about" (e.g. defence, environment, civil liberties, religious protection, etc.)

The end result is quite compelling. For example here's the page that summarises all the actions which are extremely beneficial or disadvantageous to individual liberties: https://sivic.life/tyca/tyca_individual_liberties/

FOSS toolkit for SRS and adaptive tutoring systems. Inching closer to proper demos and inviting usage.

In essence, I'm looking to decouple ed-tech content authoring (eg, a flash card, an exercise, a text) from content navigation (eg, personalizing paths and priorities given individual goals and demonstrated competencies), allowing for something like a multi-sided marketplace or general A/B engine over content that can greatly diminish the need to "build your own deck" for SRS to be effective.

Project became my main focus recently after ~8 years of tiny dabbling, and I've largely succeeded at pulling spaghetti monolith into a sensible assembly of packages and abstractions. EG, the web UI can now pull from either a 'live' couchdb datalayer or from statically served JSON (with converters between), and I'm 75% through an MVP tui interface to the same system as well.

a Slack and Discord app to help take turns (i.e. queue) with your teammates, overwhelmingly used for sharing tech resources like staging servers. It's crazy something that started so tiny (almost as a joke for my old workplace) has grown into my main "thing".

an infrastructure configuration monitoring solution for terraform/opentofu managed stacks. I am unsure how to proceed with this tbh. It's sort of the underdog in this space - it's much cheaper than the competitors. But really, it's yet to make a dent.

Generating an estimated $130 million per day (100 Megatokens/second) worth of GPT4 tokens at home will have to wait (plus I'd need to upgrade the power and AC in this room a bit to handle the estimated 750 Kw of power it would take)

Creating and maintaining an up-to-date help center is a huge hassle. In many companies there is no one that really feels obligated to take care of it.

We want to optimize this process:

- Creation: Just click through your process. We take a screenshot on every click and generate a full written article with screenshots and a GIF. You can also talk while recording to add additional context.

- Maintenance: Connect to your tools (GitHub, Asana, Slack, …) and we automatically suggest changes to your docs if your product changes.

- Consumption: Users can consume the content as they like: Read the docs themselves or ask a Q&A bot.

At the moment the creation and consumption parts are already working well. Now I’m working on the maintenance part.

90 percent of the AI companion use cases today can work well with just a vector DB to retrieve facts, and chunks of memory, but a connected digital footprint would need a graph+vector hybrid.

memory in the coming future will not just be about fact retrieval but need backlinks of memetics, new streams of data, holistic analysis, infinite schema-less key value store, causal reasoning and other things that define "who and why" of a human and imitate neuroscience's understanding of how our identities work today. this then needs to be translated as language chunks to LLMs

benchmarking this against popular tools, on longmemeval. getting good results so far. i would love to learn from you guys, what's your take on identity and human representation for LLMs in the coming future

It creates all the necessary boilerplate to generate PHP Docker containers, creates all of the MySQL users, and sets up all of the directory structures to get a new website up and running. It even helps set up SFTP users and gets letsencrypt certificates set up with certbot.

It's still very early days, but I appreciate that what used to be a bunch of commands that I would run by hand and slightly change every few months is now pretty much just all self contained. Should mean the next migration to a different server is easier.

Created in frustration because I was too cheap to pay the $50/month for a cPanel license.

If anyone here has struggled to plan a safari (or has feedback on what would make it easier), I'd love to hear your thoughts!

You can drag and drop links from YouTube, Twitch, TikTok, or Kick.

You can watch multiple streams at once in a grid and/or navigate quickly and smoothly from one single stream to another.

You can add or remove streams, save mixes for later, and share mixes via URL.

It works best on a really big screen and it's decent on a laptop. Phones aren't really supported at this point. If you have a large, secondary monitor off to the side, that's ideal for passively viewing a lot of streams. Happy to answer any questions.

We initially built it for Shopify, but now it’s fully embeddable, supports headless implementations, and integrates with tools like Klaviyo, Zapier, n8n, and Snowflake. One thing we’re especially proud of is how fast and unobtrusive it is: polls load async, don’t block rendering, and are optimized for mobile and low-latency responses.

From a tech angle:

Frontend is all React, optionally SSR-safe.

Backend is Node.js + Postgres, with a heavy focus on queueing + caching for real-time response pipelines.

API-first design (public API just launched: apidocs.zigpoll.com).

We recently open-sourced our n8n integration too.

If you're a dev working on ecom, SaaS, or even internal tooling and need a non-annoying way to collect structured feedback, happy to chat or get you set up. Feedback welcome — especially critical stuff. Always looking to improve.

Research grade orbit calculations for asteroids and comets (rust/python).

I began working on this when I worked at caltech on the Near Earth Object Surveyor telescope project. It was originally designed to predict the location of asteroids in images. I have moved to germany for a PhD. I am actively extending this code for my phd research (comet dust dynamics).

Its made to compute the entire asteroid catalog at once on a laptop. There is always a tradeoff between accuracy and speed, this is tuned to be <10km over a decade for basically the entire catalog, but giving up that small amount of accuracy gained a lot of speed.

Example, here is the close approach of Apophis in 2029:

Even though I made it as a toy/proof of concept, it's turned out to be pretty useful for small to medium size projects. As I've used it, I've found all kinds of interesting benefits and helpful usage patterns. I've tried to document some; I hope to do more soon.

The project is at a very early stage, but is finally stable enough that I thought it'd be fun to throw out here and see what people think. It's definitely my own unique spin on literate programming and it's been a lot of fun. See what you think!

Next up is a small lamp for migraines. I noticed that dim red light is much more tolerable to me than anything else. I mean obviously, darkness is ideal, but you need to do other stuff like eat and drink eventually if it's a persistent one.

So I designed a quick circuit to use fast PWM (few Mhz, so no flicker) to control a big red LED. I'd like it to be sturdy and still functional in 50-100 years, so made some design choices for long-term durability. No capacitors, replaceable LED and so on.

A simple project, but it's a busy month and I need something easy this time.

Lately, I've noticed that my (beefy) server is always clogged with background jobs that tend to run longer than they used to. It’s started impacting operations, as customers have been complaining about their backups running a bit late.

We're network bound, so I can't just add more compute power (Notion's API has a rate limit of 2700 req/15 mins). I suspect we're being getting rate limited left and right, which is causing these delays.

I’d estimate 30-40% of their S3 bill could be eliminated just by properly compacting and sorting the data. I took it as an opportunity to learn DuckDB, and decided to build a tool that does this. I’ll release it tomorrow or Tuesday as FOSS.

My secret agenda is to explore how the "information supply chain" can be tracked across the data-processing stack all the way from the original audio through transcription, the processing pipeline, and UI. I'm using language models for multi-stage summarization and want to be able to follow the provenance of summaries all the way back to the transcripts and original audio.

My son has inherited my love of cooking and baking, so we'll refine the book, add comments and photos, and eventually print and bind copies for our family and friends.

I also am hoping to laser engrave some old cookie sheets with one of my grandma's hand-written recipes. The problem I have is that it's rather faded, and I don't know yet how to make it pop for a good contrast.

Most of the documentation I read seems to have been created by a sleep-deprived robot in a stand-up or by a caffeinated squirrel with memory issues. So, I am searching for a voice to bring something different to talking about broken pipelines, observability bills expanding faster than my waistline, and heroic config file linting for the impatient.

I aim to make writing (and reading) my documentation tolerable (and perhaps even FUN!). I hope to make the next person who has to read my written word laugh and absolutely confirm my clear lack of sanity.

I store the chunks in a custom-built database (on top of riak_core and Bitcask), and I have it automatically also make an HLS stream as well. This involved remuxing the AAC chunks into MPEG-TS and dynamically create the playlist.

It's also horizontally scalable, almost completely linearly. Everything is done with Erlang's internal messaging and riak_core, and I've done a few (I think) clever things to make sure everything stays fast no matter how many nodes you have and no matter how many concurrent streams are running.

I've been basing one of the biggest financial decisions in my life - whether to buy a house - in large part on NYT/NerdWallet Rent-Buy calculators. But when I dig in, it seems that the model is both extremely sensitive to home/S&P500 growth assumptions, and that their defaults aren't well thought through.

This site is my attempt to organize my thoughts on what reasonable defaults should be, and provides an interactive tool to explore housing and S&P500 growth historical growth rates.

I'd appreciate feedback!

I discovered that VSCode has a very nice solution so I pulled the core VSCode libraries and injected them into a Chrome extension using the dependency injection, ipc / rpc, eventing to bridge the gap between all of these isolated JS contexts and expose a single, strongly‐typed messaging API, my IPC/RPC shim sits on top of each of the native environments and communication mechanisms.

Yesterday, Microsoft released the source code for the Copilot chat. Apparently, since the basis of my Chrome extension is the same core libraries I can drop the VSCode chat UI into the side panel without much friction. Although, I might continue to use Microsoft's FluentUI chat currently implemented in the extension.

Because Copilot chat has a lot of code that runs in node in Electron, now I'm working in porting all the agent capabilities for browser automation from the Copilot chat including the code for intent, prompt creation, tools, disambiguation, chunking, embedding, ect. I'm 4 to 6 weeks away from having feature parity of Playwright for automation from a Chrome extension side panel that can do most of the inference using huggingface transformer.js locally. Nonetheless, heuristics exposed as tools such that if the intent is playing a video, all that is required is a tool that collects all the video tags and related elements with metadata. No need to use $10 in tokens to figure out which video element to play.

Yeah, I think I'm 4 to 6 weeks away from having a Copilot chat in a browser doing agent automation.

If you want to see where I'm at today, https://github.com/adam-s/doomberg-terminal.

https://www.inclusivecolors.com/

The idea is it helps you create palettes that have predictable color contrast built-in, so when you're picking color pairs for your UI/web design later, it's easy to know which pairs have accessible color contrast.

For example, you can design your palette so that green-600, red-600, blue-600, all contrast against grey-50, and the same for any other 600 grade vs 50 grade color, like green-600 vs green-50.

That way you won't run into failing color contrast surprises later when you need e.g. an orange warning alert box (with different variations of orange for the background, border, heading text and body text), a red danger alert box, a green success alert box etc. against different color backgrounds.

But the environment made it hard to move fast. The systems were outdated, and there wasn’t much support for building AI tools in-house. That experience made me realize I needed to grow beyond the modeling layer. There were things I wanted to build, but I didn’t yet have the full skill set to do it on my own.

So I’ve been learning full stack development. I had built a small chatbot app before, but this time I’m applying what I’m learning toward a focused MVP for the inspection work. It’s been a practical way to connect what I know with what I want to make real.

The thing is, we’ve been retrofitting software made for humans for machines, which creates unnecessary complications. It’s not about model capability, which is already there for most processes I have tested, it’s because systems designed for people are confusing to AI, do not fit their mental model, and making the proposition of relying on agents operating them a pipe dream from a reliability or success-rate perspective.

This led me to a realization: as agentic AI improves, companies need to be fully AI-native or lose to their more innovative competitors. Their edge will be granting AI agents access to their systems, or rather, leveraging systems that make life easy for their agents. So, focusing on greenfield SaaS projects/companies, I've been spending the last few weeks crafting building blocks for small to medium-sized businesses who want to be AI-native from the get-go. What began as an API-friendly ERP evolved into something much bigger, for example, cursor-like capabilities over multiple types of data (think semantic search on your codebase, but for any business data), or custom deep-search into the documentation of a product to answer a user question.

Now, an early version is powering my products, slashing implementation time by over 90%. I can launch a new product in hours supported by several internal agents, and my next focus is to possibly ship the first user-facing batch of agents this month to support these SaaS operations. A bit early to share something more concrete, but I hope by the next HN thread I will!

Happy to jam about these topics and the future of the agentic-driven economy, so feel free to hit me up!

Work in progress...

I welcome feedback, just keep in mind that this is a work in progress, and I haven't even reviewed it for clarity and typos.

At any given time, she’s working with any number of clients (directly or subcontracted, solo or as part of a team) who each have multiple, simultaneous marketing campaigns across any number of channels (google/meta/yelp/etc), each of which is running with different parameters. She spends a good amount of time simply aggregating data in spreadsheets for herself and for her clients.

Surprisingly we haven’t been able to find an existing service that fits her needs, so here I am.

It’s been fun for me to branch out a bit with my technology selections, focusing more on learning new things I want to learn over what would otherwise be the most practical (within reason) or familiar.

- Supports markdown every where, even in your comments and replies.

- Get notified.

- Personalized feeds.

- Lightning fast & mobile first.

So I'm building it. Still early, and I have nothing to share yet, but I'm already pretty confident my Geoguessr friends will love it when it's finished.

- A home-rolled router/firewall: Using yocto to create a distribution for a router/firewall for my home network. It started as an exercise in wanting to have more control over the security of my home network, as well as see how nice of a UI/UX I can tease out of an LLM. It's also part of a (seemingly never ending) consolidation of homelab services.

- A SNES Reverse Engineering setup: A nephew of mine is starting to get into video games and is starting with a SNES but his system broke. I'm working on helping repair the console, but am also trying to set up an effective "LLM + Ghidra + SNES emulator + image generation AI + asperite plugin" to allow him to swap sprites and text in games to add some creativity and learning to the experience.

- A personal assistant system: Experimenting with agents to create a personal assistant for our house, and seeing to what extent the agents can be helpful and how much hardware is required to run something like that in-house.

- aztui: A TUI for exploring and interacting with Azure resources. I'd like to add some caching/pre-fetching logic to make the interaction with the interface snappier (one of the main motivators to create it).

I've been using GPT pretty heavily throughout, and it has been a lot of fun both using it, and spending some dedicated time looking at the models themselves along with the frameworks that support running and integrating them.

We've recently released a new archive format called ptar, it can be found on HN if interested :-)

Earlier I had some success with a couple of srats, but they aren't working any more. Idea is to have an arsenal of strategies and use whichever is performing better based on recent back tests.

More than the trading part, the fact I can leverage some ML in these interests me, plus quite fascinating how helpful llms have become especially for python programming.

I'm working on an AI thumbnail maker. You just upload a picture and pick a design type and it generates a thumbnail for you. It's still v1 and would appreciate feed back.

Surprisingly the blocker has been identifying notes from the microphone input. I assumed that'd have been a long-solved problem; just do an FFT and find the peaks of the spectrogram? But apparently that doesn't work well when there's harmonics and reverb and such, and you have to use AI models (google and spotify have some) to do it. And so far it still seems to fail if there are more than three notes played simultaneously.

Now I'm baffled how song identification can work, if even identifying notes is so unreliable! Maybe I'm doing something wrong.

We're building a chat app that automatically creates and manages your to-do list right from your conversations.

I started this for a simple reason: I was tired of the soul-crushing 'copy-paste' work of moving decisions from Slack over to Notion or Jira. So much context gets lost in that process, and it just creates more "work about work."

Our core idea is simple: a chat message and a to-do item shouldn't be two separate things you have to keep in sync. In Markhub, the conversation is the task. It's not a copy; the conversation itself becomes the to-do, and all the context is automatically preserved.

Our bigger vision is to do for collaboration what GitHub did for Git. We’re not reinventing chat or kanban boards; we’re building the seamless 'workflow layer' on top that finally makes them work together.

We're currently in a private beta and would love to hear from HN users who feel this same pain. We’ve been fortunate to get early traction with large enterprise clients (including a ~$200k on-premise deal), but now we're looking for feedback from smaller, agile teams.

Any and all feedback is a gift. Thanks!

A platform to host virtual races for fundraising events. Think Race Nights from the 90s/00s. Currently working on this with my brother, as we've both been out at risk of redundancy.

Had our first event over the weekend. Now we're focusing on marketing to local social clubs, charities and school groups.

Got a long list of future features and improvements, but this is a solid MVP. Made in react with redux, Pixi.js and prisma with sqlLite for a db.

It supports multiple languages, currencies, European VAT deductions, and more.

I built this tool for myself so it’s kinda like a personal software. Hopefully, others will find it useful too :)

Check it out: https://easyinvoicepdf.com/en/app

Github: https://github.com/VladSez/easy-invoice-pdf

My hope is to make it easier to use a computer blind than with my usual workflow with a monitor.

This means that it can cross-compile C and C++ programs that use the libc (glibc or musl) as well as the C++ stdlib (libstdc++ or llvm-libc++) out of the box without any kind of sysroot.

Still working on the realtime, memory, and game playing part. If anyone is interested, feel free to join and build.

I wrote the articles/exercises/projects a few years ago, but now I've made interactive coding and quiz widgets, using Pyodide, Lit, web workers, etc. All open source: https://github.com/pamelafox/proficient-python

- Reimagined Feed: Ditched the traditional noise—see the prompt and model behind each creation, get inspired, and check out top curated models’ performance. No more digging to figure out how the magic happens.

- Template Remixing: Creators can drop reusable templates for others to remix and build on, speeding up that creative flow.

- Curated Models: Handpicked the best for images, videos, audio, and text—think Costco quality, no endless searching or tweaking needed.

- Infinite Canvas: Reworked the workflow with an upcoming infinite workspace where creators can prompt, drag, and drop to mash up content across media.

- Built for Non-tech Creatives: Driven by our AGI-for-The-Rest-of-Us mission, it’s tailored for non-technical creators to turn imagination into reality.

- Flexible Pricing: No wasted credits—top up for up to 30% extra, never expire, plus member discounts on curated top-tier voice, image, video, and text models.

Happy to chat if you’re also into vibe coding, building consumer AI.

The big trick or the language is that it doesn't hide the pipelining you have to do to up your FMax, instead, you can manually add register stages in the places they're important, and the compiler will synchronize the other paths.

A really neat trick with this pipelining system is that submodules can respond to the amount of pipelining around them (through inferring template parameters). This way the programmer really doesn't have to think about the pipelining they do add. Examples are a FIFO's almost_full treshold, inferring how many simultaneous state there needs to be for a pipelined loop, inferring the depth of BRAM shift regs, etc.

As there is no open source version of Excel except Libreoffice, working to build the core Excel functionality with other open source packages. Then bringing in agentic editing functionality for real world data.

What is also has been interesting is to introduce banker/consultant formatting guidelines to the agent and making it beautify its work whether in tables or models.

Haven't released properly yet - not sure if it's stable but oh well.

I don't like using my personal email to sign up for things. But there are definitely things that I do want to sign up for - newsletters, try out some services.

I know there are temporary email services, but I actually want to use these services. Of course there is Apple email that forwards to your real email.

But, I also don't want to flood my inbox.

Anyway, I wanted to receive these transactional emails in my personal Slack.

So, that's what Fro is for (https://fro.app)

- Sign up - get an email address - link to your Slack channel

And you can now catch up on those newsletters via Slack.

An ISC-licensed implementation of several Content-Defined Chunking algorithms in Golang at https://github.com/PlakarKorp/go-cdc-chunkers

Whenever you have redundant data you want to store / transfer, this library lets you perform fast content defined chunking

Right now it's able to collect data from more than 30 sites with all very funky html formats with no custom code for each site.

When I began I had around 20% errors/hallucinations, right now it's way lower at around 3% errors in extraction. It's been fun and gave me a lot of experience building LLM powered data pipelines.

When I worked at larger orgs. Reviewing applicants was a very busy task. I would usually get 100-300 applications for the role. And I never trusted HR team to filter out candidates before interviews, so I would go manually through all the candidates. In the world of AI and automatic ATS systems, I have the same problem. I don't trust AI now to filter and rank candidate resumes for me. I wanted something that enhances my process, but does not replace it.

So i've started working on https://qrew.cc, where AI helps you, but keeps you fully in control.

I wanted a simpler alternative to the self-hosted SerpBear tool that I could use and share, so this is the result.

It uses SerpApi (where I work) as the data source for what actually executes the SERP scraping because it's much too complex to have purely client-side, but 100% of the rank tracking portion is client-side.

It's not fully complete and there's definitely rough edges with it, but because of the data source, it supports a large number of search engines right off the bat.

It gives me my once-every-five-years reminder of why I dislike .NET.

1. Open-Source AI Curriculum Generator(OSS MathAcademy alternative for other subjects) Think MathAcademy meets GitHub: an AI system that generates complete computer science curricula with prerequisites, interactive lessons, quizzes, and progression paths. The twist: everything is human-reviewed and open-sourced for community auditing. Starting with an undergrad CS foundation, then branching into specializations (web dev, mobile, backend, AI, systems programming).

The goal is serving self-learners who want structured, rigorous CS education outside traditional institutions. AI handles the heavy lifting of curriculum design and personalization, while human experts ensure quality and accuracy.

2. Computational Astrology as an AI Agent Testbed For learning production-grade AI agents, I’m building a system that handles Indian astrology calculations. Despite the domain’s questionable validity, it’s surprisingly well-suited for AI: complex rule systems, computational algorithms from classical texts, and intricate overlapping interpretations - perfect for testing RAG + MCP tool architectures.

It’s purely a technical exercise to understand agent orchestration, knowledge retrieval, and multi-step reasoning in a domain with well-defined (if arcane) computational rules.

- Has anyone tackled AI generated curricula? What are the gotchas? - Interest in either as open-source projects?

I'm building this website to track technology trends and usage across the most popular GitHub repositories. I parse 35K repos every week and find tech inside, aggregate it in Clickhouse, and show a summary on the website.

It was a good opportunity for me to finally learn more about Clickhouse, also trying to fully self-host on a VPS, which has its own challenges, especially regarding hosting frontend with SSR

With 20+ years of experience building an enterprise software platforms, I have seen firsthand that trying to bolt AI onto legacy systems is an architectural dead end. It’s like building a state-of-the-art 'smart penthouse' on top of a 100-year-old brick building. The foundation wasn't designed for the weight, the wiring can't handle the power demands, and you get a high-tech facade on a crumbling, inefficient core.

We decided to build the modern skyscraper from the ground up, designing the entire system around three core principles:

1. A Unified State Machine: We started with a single, transactional data model and a core set of APIs that can represent any business object or workflow. Everything from a customer record to an approval process is a primitive in this system.

2. Language as the Primary Interface: Natural language isn't just for Q&A; it's a first-class citizen for commands. A prompt like "Create an app to track sales leads with fields for status, deal size, and owner, then add a 3-step approval workflow for deals over $50k" directly executes against the core APIs, modifying the actual schema and logic in real-time. No consultants needed.

3. True Agentic Execution: Our AI agents are given credentials to this same core API layer. You can delegate multi-step, stateful tasks ("When a new lead is assigned, notify the rep on Slack, schedule a follow-up in my calendar for 3 days, and generate a draft outreach email using our template"). The agent executes this by making the same API calls a human developer would, but with the flexibility to handle variations.

For the nerds, here's the tech stack we're using to make this happen: The backend is built in Elixir; the BEAM VM's actor model and fault tolerance are perfect for managing thousands of concurrent agents and workflows. For performance-critical parts, we drop down to Rust via NIFs. Crucially, all custom logic — whether generated by an AI agent or a human — is compiled to WASM. This provides a secure, high-performance sandbox, giving us language flexibility and near-native speed for all automated tasks.

We're moving from a paradigm of "users hunting through menus" to "users delegating real work." It's an ambitious mission, and I'd love to hear what the HN community thinks of this philosophy and architectural approach.

Supporting grid, multiplayer, predictive moves, item locking and more.

It's been interesting and challenging. Probably the most important part is I've been learning a lot.

It was a lot of fun earlier on but it's becoming less fun the more I work on it.

Right now it's basically a diagramming app specifically for the domain of problem-solving. I think an issue with it is that it's too hard for new users, so I've spent the last few weeks UX designing a view (figma prototype[3]) that I think is more intuitive to use (though sacrifices some features).

I'm currently working on code design for this view and am hoping to implement in the next few weeks!

- format BigQuery SQL queries better (in my opinion). Support configurations for: maximum line length, standardize casing for SQL keywords and builtin functions (upper or lowercase). BigQuery UI does support formatting but the output doesn't look as "eye-catching" as I want.

- auto converting between standard SQL syntax and pipe syntax in BigQuery. Most queries work but some are not supported (for now - only case I see not supported as query that involves star expression in a group by since it requires the knowledge the underlying column of the table to work - though I haven't seen anyone writing this kind of group by query yet during my work)

- bring all the nested CTE to the outer of the query. this will be helpful such as BigQuery doesn't allow nested CTEs inside a recursive query. (recursive CTE will be handy if you have a CTE that is referenced multiple times - in such case, you can use recursive CTE to materialize that CTE so it is calculated once)

All this is done with the help of ZetaSQL library. I've done the code but have not yet have time to create a simple UI for it yet :)

- Create your own PDF editor with custom UI with the help of public methods which are exposed in the web component.

- You can add dynamic variables/data to the templates. What this means is you create one template, for example, a certificate template with name and date as variables and all you have to do is upload your CSV / JSON of names and dates, and it will generate the dynamic PDFs for you.

- It's framework-agnostic. You can use this library in any front-end framework.

It's still in early development, and I would love to connect with people who have some use cases around it.

I have integrated this library in one of our projects, Formester. You can see the details here https://formester.com/features/pdf-editor/

I have posted this demo video for reference https://www.youtube.com/watch?v=jorWjTOMjfs

Note: Right now it has very limited capabilities like only adding text and image elements. Will be adding more features going forward.

News Perspective Gap Compare how major events are reported by local vs international outlets (e.g. Taiwan election coverage in Taipei Times vs BBC)

Price Transparency Settle debates like "Are Xiaohongshu prices real?" by checking identical products on U.S/Walmart and China/JD.com simultaneously

Authentic Connections Join discussions on 2channel (Japan) or Reddit (Brazil) without VPN, preserving original language/cultural context

Tech approach: Country-specific keyword routing (like valentin.app for search) Lightweight proxies to bypass geo-blocks (no data storage) Crowdsourced local portal directory Would love feedback from globetrotting hackers!

Among other things, my team has implemented access-based sharing using web links, like Google Docs for real paper handwriting. And we've just launched Quin, our AI assistant for real paper handwriting. Super useful for getting help with math, language learning, looking up relevant facts, generating ideas, etc.

I’m trying to build a consolidated database of PFAS free products that make it easier for shoppers to find safe foods, cleaners, clothes, and other products families commonly use. The database shows not only the product, but the reason it’s considered pfas free; sometimes all you have to go on is the brands word, sometimes there is third party testing for pfas, sometimes there is a material issue justifying it. We tried to present it all for the consumer to easily decide. Users can search, or browse for products using categories.

The database is here: https://database.pfasfreelife.com/

I think there is a gap between exploratory testing and more structured forms of testing. So I am trying to make a tool for that for myself. If I like the outcome I'll open-source it.

I used to have an integration in Spotify, that automatically copied my "Discover weekly" playlist into an archive. Over time, it grew close to 10000 songs. It also started to get polluted by ambient sound and kids songs when my daughter was born.

I wanted to clean it up but as far as I could tell, the only way was to do it manually, song by song. I'd want to have something more powerful, that would easily let me rearrange/split/curate my playlists based on any arbitrary constraint.

I scraped HN's 1000 most mentioned books and visualised them. This month I used a new embedding model (Nomic), switch out UMAP for PaCMAP, and added automatic cluster labelling.

The clustering and dimensionality reduction aren't quite as stable as I'd like, but most seeds give decent results now.

An AI native issue tracker without manual task management

The process itself is extremely time consuming, when done manually. My application speeds up the process by a factor of 50 up to 150, depending on how you measure it.

Finally it allows "everybody", to find the 0DTE trades, that are really profitable - something, that currently only the "Pros" can do.

Im working on simplyfing the code further. I tried really all of the "productivity" stuff to stay organised. Got angry multiple times, went to pen and paper, was OK, but i felt i just need a slight glimps of tech to make it more functional. Something little more than plaintext file, but not much.

How We Met – https://how-we-met.c47.studio/

Each day, I create a new 30-second episode based on the plot direction voted on by the audience the day before.

I'm trying to see how far the latest Video GenAI can go with narrative content, especially episodics. I'm also curious what community-driven narratives look like!

For the past week, I've been tinkering mostly with Runway, Midjourney, and Suno for the video content. My co-creator vibe coded the platform on Lovable.

Custom high performance C++ / OpenGL/WebGL engine. Uses Jolt physics and Luau and Winter scripting.

It's a lot of fun and pretty challenging code.

It's free (https://github.com/welpo/ab-test-calculator), and it has no dependencies (vanilla JS + HTML + CSS).

Right now it only supports binary outcomes. Even with the current limitations, I feel it's way above many/most online calculators/planners.

* of its ability to store unit system data as code

I'm also working on learning about building software with LLMs, specifically I am building a small personal project that will allow me to experiment with them using measurable hypotheses and theories, rather than just tweaking a prompt a bunch and guessing when it is working the best. I know others have done this, but I am building it from the ground up because I'm using it as a learning experience.

I plan to take my experimentation platform and build a small "personal agent" software package to run on my own computer, again building from scratch for my own learning process, that will do small things for me like researching something and writing a report. I don't expect anything too useful to come out of it, since I am using 1.7B/4B models on a MacBook Air M2 (later I might use my 3080 but that won't be much improvement), but it will be interesting to build the architectural stuff even if the agents are effectively just useless cycle-wasters.

We're headed into an era of massive white-collar reskilling.

Conjtest is a policy-as-code CLI tool which allows you to run tests against common configuration file formats using Clojure. You can write policies using Clojure functions or declarative schemas against many common configuration file formats such as YAML, JSON, HCL, and many others (full list in repo).

Under the hood, it uses Babashka and SCI (Small Clojure Interpreter) to run the policies and Conftest/Go parsers for compatibility with Conftest (https://www.conftest.dev/). It’s also possible to bring your own parser or reporting engine using Babashka scripting.

The initial big pieces are in place now, I’m preparing my end of the year to talk about Conjtest and get some feedback/issues to work on.

I wrote an MCP server in C#/.NET that let's LLMs safely generate an run JavaScript using the Jint interpreter.

It includes a `fetch` analogue using `System.Net.HttpClient`, as well as `jsonpath-plus`, and a built-in secrets manager.

The prime use case is working with HTTP REST APIs with an LLM. With this, you can let users safely generate and execute JavaScript in a sandbox.

Tech stack: - Python + opensubtitles.org for the data pipeline - Whisper for speech recognition - React Native for the mobile client

Current state: tech demo. The app works fine and already helps a lot — for me and my wife (both non-native English speakers) it makes watching movies in Dutch cinemas much easier, by showing English subtitles on our phones instead of the Dutch ones provided by the theater.

The biggest issue now is subtitle quality and legal status. Opensubtitles provides a lot of data, but the quality is often questionable, and the legal status is rather gray/black.

Any legal or data-related advice would be appreciated!

The latest version supports dataview tasks format and multiple reminder lists with Routing Rules.

I think the product is pretty much feature complete now so I’ll probably start doing some marketing and move onto coding something new. Sales until now have all been organic.

As a data engineer, I regularly have to dig through massive files to debug issues or validate assumptions — things like missing column values, abnormally large timestamps, inconsistent types, or duplicate records. It’s tedious and time-consuming, and that’s what led me to build this.

ZenQuery makes it quick and easy to explore data locally, without needing to spin up notebooks, write scripts, or upload anything to the cloud. It’s also useful for doing lightweight analytical QA if you're working with business data.

Happy to answer any questions.

I'm currently working with a few clients and using their feedback as guidance. Let me know your feedback if you use it.

I love SSGs as they’re simple and fast and the sites they make can be hosted anywhere with little maintenance. But, after helping a non-technical friend get up and running with one, the UX is rubbish.

So I’m building a combined CMS and SSG called Sparktype, designed for writing and publishing. Users can create pages or collections, write and export the generated site. At the moment it exports to zip, but I’m working on connecting to Netlify or GitHub for automatic deployment.

My goal is to build something that allows people to create a publication with the ease and polish of say, Medium or Substack, but which is completely portable and will work on almost any hosting.

It’s very early MVP - the editor works, but the default site theme is rough around the edges and there are a bunch of bugs. I’m currently working on getting it good enough so that I can create its own marketing and documentation site with it.

I’d love any thoughts or feedback you might have.

Also working on an email communication assistant https://merel.ai creates draft responses for gmail and outlook based on your company data, email history, website content and extensive organisation settings. Still work in progress as well.

I'm trying to make i18n easier, integrate it better with CI/CD and automate it more with LLMs (for now in Go, second priority is TypeScript and other languages later).

For this I had to develop a completely new approach and subsequently a specification for the "textual internationalization key" (TIK) which are programmatically translatable to ICU MF.

Toki is the first TIK processor implementation for Go.

Struggling to get the generated iterations to be up to a standard I'm happy with at the moment, but improving every day!

So I made a proof of concept app on iOS that uses gmail API to send out newsletter emails. I wish I could just send prepopulated emails (with inline attachments and recipients) to iOS mail client instead of asking for gmail OAuth permissions, but it doesn't look possible.

Now I'm trying to create a polished app for alpha testing. Been exploring data persistence (Swift Data, Core Data, rxdb etc) and settled on Core Data. Architecture wise, I've settled on MVVM + Swift UI. At the moment I'm trying to figure out how to make mocks and XCode preview data geneeration ergonomic.

So far, I am pleasantly surprised at Swift and iOS development, but I still hate XCode.

In Fostrom, devices connect via our SDKs or standard protocols such as MQTT and HTTP, and send and receive structured, typed data, through pre-defined Packet Schemas. Each device gets its own sequential mailbox for messages. You can trigger webhooks or broadcast messages to other devices based on incoming data, powered by programmable actions (written in JS).

We entered Technical Preview recently. Since then, we've been working on:

- Major upgrades to Actions: making it easier to write action code, along with testing before deploying, and more docs on how to write good actions. Coming this week.

- We're in the process of releasing Device SDKs in multiple languages, including JS, Python, and Elixir soon. The SDKs are powered by an underlying lightweight Device Agent written in Rust.

- A new data explorer to view and analyze your fleet's datapoints, which will be available in a few weeks.

Happy to answer questions and appreciate any feedback.

I didnt realize how much overhead an sfml window draw call has, granted I have yet to target optimizing that yet.

Seems like my first candidate for multithreading; also I think the scheme I implemented for how to manage texture/sprite switching is advised against and may need to slightly refactor how I store and swap based on object state.

Yeet

What's different about it is that we've figured out character consistency with AI generated images, as well as text legibility. Most AI models don't do small text very well, and don't do consistent characters. We've tried to fix that.

Going from Manifest to OCI is a bit tricky and performance for calculating total storage based on metadata is hard to get right. But the result is that we own our full registry implementation and can take it any direction we want. Quite happy with that!

I don’t want to auto compose messages or anything. I just want the computer to filter out things I don’t care about and tell me the answer to things without hunting around my inbox.

Think of it as a Plex for the digital copies of comics. Point it to a folder full of comics, and it will infer metadata, and present your collection in a Plex-like manner.

ThreeTwo supports Comicinfo.xml, Metron's format. Generally there is no universally agreed-upon metadata format for comic books, comic book archives are essentially .zip or .rar files with images with a fragmented naming convention. ThreeTwo itself uses regexes to parse filenames and match that against ComicVine to extract metadata from there. This is currently the problem I am trying to attack.

Other than that, it integrates with DC++ via AirDC++, and also incorporates an OPDS server.

Peekly pulls from high-quality sources using LLM + retrieval, then sends you a regular digest with just the most relevant content according to your interests. You can even give it custom prompts to control what it finds and how it summarizes — super useful if you want a particular angle on a topic.

It's built using Nuxt because I've never really played with Vue before and it seemingly comes with all I need for a static, markdown-powered blog. I guess what's been stopping me was me bothering too much about "When is it good enough to be online?" and "What should the first post be?". But I'm trying to get rid of the perfectionism by just putting it out there and just posting something. I think I'll reflect on this in the first post.

Elevator pitch is: A simple searchable directory of various procedurally generated toys. Think Boids, Game of life, Maze generation, terrain generation, etc. written in Ts/Js. Anyone can contribute and will get their page for their implementation of a given ProcGen.

This is optimized for

1. Hobbyists wanting to make a ProcGen and have it be publicly available

2. Game Dev's & Academics looking for inspiration

3. Students / Amateurs looking for a project to add to their portfolio. It's specifically aimed at making the barrier of entry for your first "out-in-the-world project" as low as possible.

Long term vision will include bounties i.e. "I'm looking for a terrain generation algo that makes one main island surrounded by 6-12 smaller islands, some connected by a bridge, and every island should have an organic coast line with coves & bays and stuff".

There will be a voting system so clean, polished, well documented implementations of a given algorithm float to the top, (i.e. Game of Life) might get procgenzoo.com/CellularAutomata/GameOfLife.

The plan is to keep this free forever, and hoping donations cover hosting fees.

I'm also working on BackPackReact. Which is an inventory management game where the placement of various components inside yourback will create & consume resources to power your jorney to the next trading post. I.e. Fire/{HeatSource} and Ice/{ColdSource} on either side of Thermoelectric Generator will generate Power, which enables your vehicle to keep moving.

But it's a balancing game, the more space you use for your machinery, the less space you have for inventory for your cargo. You want the most efficient "engine" but also enough supplies to handle any unexpected events.

Is it better to build a nuclear reactor? Or just fill up on wheat and rent & feed a horse to pull you to the town, so you can sell all excess wheat you didn't use? Should you spend money to gather intel on the trading price of Iron is at your destination city? Or pick up a contract to build an electric grid at the new settlement, which will require many trips but yield one large payout?

Would love feedback on either of these ideas :) & if you would contribute to or play either.

Although it should compile to any platform, I want to take advantage of the new Foundation Model sdk Apple announced at WWDC.

I also recently released something called slackprep, a CLI tool and Python library that wraps slackdump, converting Slack export data into LLM-groomed Markdown transcripts.

That includes labeling inline images organizing them for upload as LLM context.

I see these and other utilities coming together to assist in assembly of deep context for system level design.

Wanted workflow orchestration without infrastructure to store workflow JSON/YAML in database/S3/CDN/whatever and execute it on Cloudflare Workers, in the browser, etc.

The magical part about the serverless workflow spec: native JSONSchema support for inputs/outputs at both workflow and task level. This creates composable, Lego-like tools for AI agents - each tool is just a workflow reference that can be fetched on the fly.

I built it because I was blown away with what the latest image generation models can do and found that interior design is one area where it could already provide significant value for people. I’ve already used it in just about every room in my house to help me decide on:

- which paint color I should use

- how I should arrange my furniture

- what color theme I should be using to match the design I’ve gone with

- general inspiration on decor

It’s free to download to try with sample imagery. Unfortunately due to the cost of image generation, you won't be able to upload your own photos in the free version (yet). But I’m constantly improving the app and would really love some feedback.

like, it would be very cool to do something like have your feature branch be deployed to a separate pod in dev cluster, and have an ingress rule set up so that it points to that pod only.

So if your dev environment usually points to <some-app>.dev.example.com,

Deploy your feature branch to a dev cluster, but on a different pod. Then have it reachable to <some-app>.feature-branch-1.dev.example.com without touching main.

I think it's a neat idea and I'm sure it should be possible if I configure some istio settings.

TestingBee is a way for startups to get part-time QA for their product's critical flows.

I've been working at startups for the last four years and I've consistently been on teams struggling to balance launching quickly versus keeping our product working. We've never had success creating a substantial test suite because our product is changing too fast and engineers are too overloaded.

I built testingbee as the solution. It lets you write your app's flows in plain english and the bot I created will execute those flows in your app as a user would. This triggers on every push to make sure every release keeps your product working :)

I am working on the world's first end-to-end Database Migration tool, supporting Oracle to PostgreSQL and MSSQL to PostgreSQL database migrations with AI for Schema Migrations. Until now, people used different tools for Schema Migration and Data Migration/Replication. During this process, we ended up building a data migration and replication tool supporting any databases between Oracle, SQL Server (MSSQL) and PostgreSQL databases.

I am particularly enjoying the Stern-Brocot tree exploration: https://calc.ratmath.com/stern-brocot.html#0_1 I hope people will find it to be a nice way of understanding good rational approximations and how they tie into continued fractions and mediants. A nice exercise is to type x^2 in the expression box and go down the path to always advance towards x^2 being 2. This gives the continued fraction representation of the square root of 2.

Just prototyping at the moment, but the goal is to allow users to not only share files (even big ones) but also forms, like Google forms, but encrypted and one time only (read once).

The use case I have in mind is allowing businesses to create GDPR forms (with private info, consent, etc), share unique urls with specific customers, and once the data is received by the business delete it from the server.

This could be useful to businesses that don't have a customer-facing portal, but have to deal with PII and the customer needs to consent and verify the data and what it's used for.

The data is encrypted client side (web crypto) and the password either shared in the url (in the hash fragment, also encrypted by a key stored on the server) or by other means (eg. could be the recipient's dob or id number or some other previously shared or known value).

Still trying to figure out the details, use cases, business value but the core backend is done so is the client-side crypto stuff. I managed to get chunked AES-GCM working so that it doesn't load the whole file in memory in order to encrypt it, it does that in chunks of let's say 2MB. Chrome also has chunked requests (in addition to responses) for sending the file to the server, but would probably need to come up with some other mechanism to get that working on other browsers (like send the chunks in multiple requests and append to a single file on the server, but that adds more complexity so I'm still working it out).

Besides, I have initiated two series on my blog: T4P and GenAI on my blog and writing about Algo trading and GenAI stuff(https://blog.adnansiddiqi.me/)

Node based visual editor for 2D LED patterns over BLE. Web/iOS/Android app to ESP32, works with most addressable LEDs. It’s like TouchDesigner x WLED x PixelBlaze, but Bluetooth so you don’t need annoying wifi setup. And hopefully you can make much more interesting patterns without touching any code.

Eventually the ESP32 devices will save all the patterns they’ve seen and share them with apps that connect to them. So there’s a pattern ecosystem, like Electric Sheep.

Still rough and in progress (and constantly deploying so it may break for you )

So we decided to build out our own filesystem adapter and recently deployed it. It's pretty exciting to have our own solution that does exactly what we need and appears significantly faster.

It makes us want to open source pgs.sh because it has fewer dependencies in order to deploy.

The tool will support four annotation modes: Box, Polygon, Mask, and Keypoints — each with its own dedicated panel. You can switch modes by clicking the color-coded buttons on the toolbar, complete with smooth transitions. Labeling is a tedious task, so a bit of satisfying UI action here and there can't hurt.

It will also export labels to all major formats — and can (re)generate any sidecar file structure when needed.

I also have some ideas of a programming language designed mainly to process files in DER format (as well as data from stdin and to stdout), but have not actually implemented anything so far.

I also have ideas about an operating system design and computer design, and should have help to write the specification properly, and then it can be implemented afterward.

I'd previously tried to learn TLA+ a few times but always eventually lost interest and gave up. This approach was quick and easy.

I’m working on a name generation tool that uses 83 structured naming methods. Examples: React (Verb-based), Vue (Obsolete English), Facebook (Compound), Netflix (Portmanteau), Lyft (Creative Misspelling), Alexa (Personal First Name), etc.

I wasn’t happy with the slop generated by the overly general name generators or my own prompting/brainstorming. I went on a tangent and read the top (5) books on naming from Amazon. From there I was able to create very specific and detailed prompts which started producing consistently good names, the odd great one, and a small amount of crud.

Eventually this escalated from a large spreadsheet of detailed prompts to a side project.

Please give it a try, I’d be happy for any feedback on this early version. (I recommend the options tabs for some granular tweaking)

Just got this POC up and running the other day. Realistic sample data for prototyping and testing is frequently a pain point. Even more so for anything having to do with email.

So I wanted something that would pretend to be someone and send and respond to fake emails. And it seems like local LLMs are more than capable of this nowadays. Uses Ollama. Vibe-coded with Claude. UX designer here so be gentle.

Our goal is to make DevOps easier. We want to provide simple (yet scalable) solutions on AWS, Azure, GCP.

You pass your own credentials and we deploy the infra into your tenant.

Health insurance is one of the earliest, most important decisions immigrants make, and they often choose wrong. It can delay visa applications, cause coverage issues, or create expensive problems down the road.

Now they click a few buttons and get very specific recommendations explained in plain English. If they're confused, they can involve an independent insurance expert for free. The guy replies within an hour or two, and is cool with Whatsapp. The way I gather feedback from users, he's strongly incentivised to stay honest.

There is no AI involved, just good old-fashioned business logic. It means that the advice is sound, well-tested and verified by multiple competing experts.

It's such a far cry from either trusting whatever reddit or your employer tells you, or the slow back and forth of getting a quote from a (possibly dishonest) broker.

The second version[0] has been live for about a month, and the results are phenomenal. This third version vastly improves the quality of the advice, adding information about gap insurance for visa applicants, and making actual recommendations instead of listing all options.

It's a really fun project, even if the topic is boring. It's a great research, UX, copywriting, coding and business project. It's the product of a few months of hard work, and so far it seems to pay for itself.

Idea is to be the uptime monitoring + status page solution software teams choose. Next big project I'm looking at is making a terraform provider for uptime checks, so setting up alerts for your new microservice becomes seamless.

Still years away from employing me full time, but we're getting there.

The other more recent is a web based CalDAV client for Todo items. I love the tasks.org mobile app and can't stand the Nextcloud Tasks UI so I'm making an alternative that'll be local first and simple but fast.

We launched this month and are growing fast which is exciting. I'm mostly impressed by how easy React Native has gotten, as a long-time native Apple Platforms dev, given all the training LLMs have on React.

The goal is to make the code better organized, easier to read, maintain and extend.

We're off and running, making the world's best configurators for complex products. Our first clients love us. Our configurators implement some very personal ideas about front-end state management, and it's really a thrill to see it all working with real products, 3d rendering and zero latency.

It is like MS Word "Bullets and numbering" but it's a small UNIX filter, no GUI, much faster and smoother than MS Word or Google Docs.

Perhaps the beginning of a markup language for text or HTML files intended to be converted to MS Word.

The levels are procedurally generated with heavy curating and additional manual tweaks. I'm also adding a narrative later to each puzzle myself. It's a rare type of puzzle, since few puzzles have means to convey any kind of narrative.

My next big additions will likely be a tutorial, and profile page where you see your results and how they compare to other players. But this being just a side thing, it's progressing really slow...

But working on it for past 7 months. It's running and I'm tweak/adding features while marketing it.

It introduces quite a few changes. In my shipping apps, I'll probably be simply telling the OS not to use Liquid Glass (for now), but for my various test harni, I will need to adapt. Looks like a fair bit of work.

An HP Deskjet 5850. Typical small home/office printer.

Thanks to a brilliant owner years ago who figured out you can use the drivers from the model 9800. A larger-format printer whose drivers seem to cover a lot of ground for printers of certain vintages, easily including ones like this one having more limited paper size options. The printer works quite well on the latest Windows 11 now, it's just not a one-click affair to install like it was with Windows XP.

By this late date, the driver download has been slightly hosed. Files are basically from Windows Vista x64 but are not prepared to install like you would want them to, there is actual uncorrected damage to the structure. Once you unzip the drivers into a C:\drivers\ folder for instance, then after you manually install the .INF file found in C:\drivers\ it's supposed to allow you to later manually select a driver from among a number of similar vintage HP Deskjets. All the driver files for that variety of different printers are right there in the C:\drivers\ folder, right next to that one INF that covers them all. But the install routine can't find any of them because it looks for them in a "hard-coded" C:\drivers\amd64\ subfolder which somebody forgot to spawn.

Then if you manually make a new C:\drivers\amd64\ folder, place an extra copy of the unzipped fileset into C:\drivers\amd64, then install the INF from there, it proceeds to search for the drivers in C:\drivers\amd64\amd64\ and fails to find them again :\

Try it again, pointing at the INF in C:\drivers\, and with the extra copy of the fileset (less the INF) already present in C:\drivers\amd64, then it works.

And that was before "Print Nightmare" a few years ago.

Since then the "normal" steps that follow have gotten worse every year, maybe more often, additional hurdles and barricades keep popping up.

Plus you can only imagine the fun, sharing the printer with Windows XP like nobody knows the difference.

It's almost like Windows is a challenging videogame which keeps coming out with new versions where it gets more difficult to make it through all the levels, and when you do, you reach pretty much the same final goal you had before you got the new version :\

I recently shipped a first-draft UI demo that you can play around with for my self-hosted jobs tracker:

Now I have wonderful crashes and hihats cutting through the guitars and bass, without the snare and kick overpowering everything. This also taught me some insights about balancing relative volume levels and/or lowering dominating buses against each other and compensating upwards on some upstream bus as necessary, which I think also improved the balance of the entire rhythm section.

Except, now I'm kind of unhappy with my kickdrum sound. Some of the bands I listen to and saw at the festival I just was on have some amazing, epic kick drum sounds. It's like a giant mountain troll hammering into the gates of a castle and - on the right PA - kicks you right in the gut, literally. We had a good laugh a few days that some dudes jacket moved with the kickdrum. My kickdrum currently sounds more like wet cardboard flopping against a wall though.

Besides that, I'm however looking at moving some of my notes on audio engineering on linux onto a blog to end up with something like Protondb at a smaller scale, as well as some of the steps and things to do to get audio plugins working on linux, what audio plugins work well, which I could not get to work. I am just realizing, I need to learn quite a bit more about wine, architectures and such to write good articles and ideas about this. But maybe that's my perfectionism speaking.

If you're reading this and are yelling "But what is the magic?", the magic is largely called yabridge. Many simpler plugins just work with that. It may not be up for professional audio engineering, but it certainly is up for home recording and dabbling around.

A residential proxy network that leverages blockchain by turning everyday users home connections who have no contracts against such practices, into rentable exit nodes, each contributing bandwidth in exchange for rewards. A dedicated blockchain ledger tracks the exact amount of data each node relays and automatically releases micropayments in the network’s native cryptocurrency, ensuring transparent, real-time compensation without a middleman.

But with my adhd, I'll likely end up working on another project sooner than later. Interested in MCP aggregation.

I'm currently adding support for letters in addition to Postcards

Features:

  - Local. No internet connection needed.  
  - Manual. Every transaction is added by the user.
  - One-off or arbitrarily recurring transactions.  
  - No lock-in. Check out your data any time.  
  - Arbitrary metrics to track performance. 
  - Hosting on the cloud for mobile access. 

I've been using Google sheets + forms for the last 8 years to track my finances. It's worked well, except for minor inconveniences. This app is my answer to my own problems.

Now I am getting a lot more time to focus on creating content about my journey and sharing it. Test coverage is still pretty bad but I do not feel the generated product is worse than it would have been if I coded it with or without LLM assistance. Right now, I barely see generated code.

it now takes every other minute a webcam pic of me to see whats going on

Also, organising specific topics for each month up to 2026.

Document translator that keeps layout and formatting

The MQTT routing backend is fully automatic. If two nodes are connected to the same MQTT server, or within range of gateways that are, they communicate.

The web client communicates directly with MQTT, meaning you can chat and set registers on devices without having hardware.

Frankly, I'm astonished that it hadn't collapsed out from under me when I was shoveling snow off of it this past winter. Behind the ledger that tied the balcony to the house was a mess of pressure treated lumber scabbed into a cavity in the logs formed by rot, none of it well-fastened or fastened into truly sound wood.

With some friends, I've been building "Mo Money": a Duolingo-style app to teach investing through a gamified mix of microlearning and a real-time trading simulator (but it's a game). It's meant to be built as much for total beginners as it is for amateurs.

Sim side: A fully playable trading game backed by historical market data (no real $$), it's now integrated with a FastAPI backend, WebSockets, Firebase (soon), and XP system to track skill growth and gamify progress.

Learning side: A clean microlearning stack that teaches financial literacy in snack-sized bits, a lot like Duolingo, it's interactive, level-based & accurate and relevant information in the most digestible format.

Just added: a lightweight AI tutor for contextual Q&A during lessons. Thinking of adding a little more AI than a chatbot potentially to help learners in the app.

Upcoming: XP-linked achievements, a leaderboard, and a light paywall via Buy Me a Coffee.

We're undergrads building this from scratch, aiming for early users soon. If you’ve ever thought “I wish someone made markets feel learnable,” we’re trying to do just that. super excited

It's called SmartSearch - uses SentenceTransformers for embeddings and FAISS for fast similarity search. Best of all, it runs locally on your computer.

Why? I absolutely despise Mac's search. I want to be able to search within documents, images, pdf etc.

It's called Heap. It's a macOS app for creating full-page local offline archives of webpages in various formats with a single click.

Creates image screenshot, pdf, markdown, html, and webarchive.

It can also be configured to archive videos, zip files etc using AppleScript. It can do things like run JavaScript on the website before archiving, signing in with user accounts before archiving, and running an Apple Shortcut post archiving.

I feel like people who are into data hoarding and self host would find this very helpful. If anyone wants to try it out:

It’s built in nextjs and Django, with integrations for OpenAI, perplexity and all bedrock models. And MCP of course.

Feedback and requests welcome, I’m terrible at marketing so we have very few users but we use the platform ourselves and we’re super happy with it.
