A very simple idea: when you eat more than your maintenance calories, you gain weight; when you eat less than your maintenance calories, you lose weight.

By using an algorithm, we can accurately figure out your maintenance calories more accurately than traditional regression based formulas like katch mc ardle.

It's way more accurate than calorie burn tracking devices like fitness bands and watches. (garmin/apple watch etc...)

MacroCodex helps you spot dips in maintenance calories from metabolic adaptation, then auto adjusts your calorie target and macros so your plan stays aligned with your real maintenance calories (TDEE).

It's very useful to those who find it hard to gain or lose weight.

it's a completely free app, no paywall, no unnecessary data collection.

Super interesting. I’ve been failing hard at gaining weight. Intrigued. I hope you don’t hesitate to make the app paid if you find the justification.

I’m working on Peak Flow Meter Diary, a simple app to help people with asthma record peak flow readings more easily, then combine those records with environmental data to provide earlier warnings about possible triggers.

In the UK alone, around 7.2 million people have asthma. Globally, WHO estimates that asthma affected 363 million people in 2023 and caused 442,000 deaths.

Peak Flow Meter Diary is not meant to detect every possible trigger. It will not warn you if someone suddenly sprays perfume nearby, or if a dusty bag is opened in the same room. But it could help with risks that can realistically be monitored ahead of time, such as weather, pollen, pollution, cold air, storms, and similar factors. The aim is to make daily tracking easier, show simple visual warnings and notifications, and make it easier to share useful records with clinicians.

I’m also trying to build it in a way that reduces paper, plastic, and electronic waste. If funding allows, I would like to make the project carbon-negative.

That is the bigger dream: to make a small example of how even modest start-up can think about environmental impact from the start, and use it as a practical showcase.

The pitch and full project explanation are here: https://www.kickstarter.com/projects/why5/peak-flow-meter-di...

Feedback welcome, especially from anyone with asthma, clinicians, carers, or people who have worked on health tracking tools. By now I know that my kickstarter is not going anywhere, so I would value any input was the idea that bad, or lack of marketing and accessing appropriate groups etc. I think this community has a lot of experience so I would like someone to share what could have I done better. Do not be shy to tell me if you think idea was waste of time.

I'm working on Totem (https://totemkb.com), a collaborative knowledge management system built entirely in Rust without any HTML or web-tech. Currently supporting Windows, MacOS, Ubuntu, and iOS (although the iOS build is currently in review).

Although the goal is to build an efficient all-in-one-workspace, I wouldn't run a company on it just yet. Right now I'm looking for early adopters who don't mind the rough edges and relatively minimal feature set.

You can grab an early build at https://alpha.totemkb.com.

New workspaces will be in a 14-day 'trial' mode, email rohit@totemkb.com if you'd like me to upgrade your workspace free of charge.

Currently working on HN Alerts — a simple free site I made to alert me (via email) to trending stories on Hacker News.

It sends me an email once a story hits a certain number of upvotes per minute, so it's useful for keeping track of breaking news.

It'll also soon allow you to get alerted to specific words or phrases in titles. (I have one set up so the monthly hiring threads notify me as soon as they appear.)

https://hnalerts.com

argee• 1 month ago

It sends me an email once a story hits a certain number of upvotes per minute

So do you get one email per-story that fits this criteria? Or is it some kind of roll-up?

davidbarker3• 1 month ago

Typically one email per story.

It checks every 5 minutes, and if more than one story happens to meet the criteria during that 5 minute bucket then it'll put them into one email (so the "hiring" checks appear in one email). But in reality because it's rare that 2 stories will trend within the same 5 minute bucket it ends up being one email per story.

I'm using an old domain to put together a curation of film edits set to music

https://brodlist.com

yodon• 1 month ago

If you're not aware of "sync rights", it's probably worth reading up on given your interests. There is an entire specialization of music copyright law focused solely on synchronization of music to visuals. The good news is that studios almost never obtain this set of rights to the music they publish (because historically there wasn't enough money in it to justify negotiating for them).

david9273• 1 month ago

Fair use copyright covers areas such as this.

david9273• 1 month ago

Thank you for taking the time to say that. I really appreciate it.

When YouTube was new, a guy named JT Helms made that top one (Once Upon a Time in the West cut to Arcade Fire) and when Bruce Springsteen was asked if he liked anything on YouTube, he said that. And it made me happy because it was my favorite too. And I thought we were on the cusp of something like a new art form.

I still think that. I'd like to see short films shot to music as well.

Been working on making it much easier for application deployments to get access to a isolated database/schema. The usual pattern currently is to assume that each app creates a new database, which ignores the backups, monitoring etc required for each database. Implemented support for Postgres and MySQL.

Adding agents to my SQL canvas (https://kavla.dev)

Here's a live example of it figuring out when to post on HN: https://kavla.dev/hn (spoiler, its noon UTC on Sundays)

And here's it generating an interactive map of 20000 earthquakes: https://kavla.dev/quakes

I feel like the canvas is actually a great way to interact with an agent, everything it does is visible, so auditing what it did is (relatively) easy.

I still got some credits to burn so agent usage is free atm (you still have to sign up to use it though)

[NO-AI]

My wife and I continue to work on Uruky [1], a simpler Kagi alternative, based in the EU.

Last month we launched image search (got out of beta this month), added our own index and crawler (via Uruky Site Search [2]), and reached 100 monthly active accounts (we’ve passed 150 now)! You can also see a privacy-focused independent blogger wrote about us [3]!!

You can check out the main differences between Uruky and Kagi, DuckDuckGo, SearXNG, etc. in the footer (right side), but one huge difference is that with Uruky, after being a paying customer for 12 months, you can download a copy of the source code (licensed as BUSL into AGPLv3 in 2 years — a suggestion made here in HN)!

You can also now get a free trial for 2 hours when you signup if you pass a proof-of-work captcha (another suggestion made here on HN, and it uses a local Altcha).

Our main challenge continues to be discoverability and outreach because we want to do it ethically. Ideas are welcome! We’ve been sponsoring open source projects, open source maintainers, and indie, small-web, and privacy-related websites and applications.

Feature-wise, for June we’ve already added a ton of personalization and privacy-increasing features like URL rewrites, cash-by-mail payments, and anonymous vouchers! Upcoming is partnering with ProxyStore to sell vouchers (we’re currently in talks for this), so you can buy vouchers with XMR/Monero or other cryptocurrencies. Then we’ll be looking into increasing our own index, focused on indie/small web.

Thank you for your kindness!

I'm rooting hard for Uruky. Is it showing any traction? I would love to hear this turn into a story where it sustains your family and a few employees.

BrunoBernardino5• 1 month ago

Thank you so much! We would definitely love to have that happen, too! We couldn’t have imagined we’d get to 100 monthly active accounts so soon (and now past 150), but we’d need at least an order of magnitude more in order to have it be sustainable as a full time business for us.

That being said, it definitely looks possible, so we’re excited! As it stands, it’s already sustainable part-time and can go long-term.

maxmoehl• 1 month ago

Since you are based in the EU you could try to get on https://european-alternatives.eu/category/search-engines (or any other page listing EU-based alternatives to foreign services).

Surprisingly, my Kagi search for “eu alternatives” to get the link showed this blog post: https://yeechie.nl/uruky-kagi-alternative-eu-based-private-s... as a second result, what a weird coincidence.

BrunoBernardino5• 1 month ago

Oh, wow, thanks for sharing, I wasn’t aware of that post! We’ve tried to reach out to European Alternetives before, but never got a reply, unfortunately.

benliong78• 1 month ago

Uruky sounds like the google that we used to have: one that's just good because it returns relevant results, not because of ecosystem lock-in.

That being said, can't help noticing the [NO-AI] at the beginning of the post, and I wonder whether it would help adaption if you also make the search engine available to agents for paid customers.

BrunoBernardino5• 1 month ago

Thanks for commenting! We do not "forbid" AI or are "anti-AI". You can use agents within the rate limits (which are public in the FAQ).

We don't plan to build AI tools into the search (specifically Gen AI/LLMs).

But the tag mostly indicates that the product is built "by hand", not "vibe-coded", and that it's not about an AI-related product/service, if that makes sense.

There’s a Unix CLI tool that implements an accurate version of this… check out /bin/yes.

ynxshiny2• 1 month ago

not quite, it doesn't just flag everything as false. Some hustles come back with high legitimacy scores and realistic income ranges that actually match the claims, but might take longer to earn the first dollar. The point is separating the method from the creator's real monetization — sometimes they're the same thing, sometimes they're not. if people are gonna fall for these quick hustle tactics and lose money, id rather them use this and make sure its not a full waste of time

CRM with agent baked in that can properly do stuff. No idea why attio/twenty are soooo bad at this. It's a table. getcrme.com / https://github.com/ChristianSch/crme

and gargoyle, an activitypub server with a (theoretically mastodon compatible UI) https://github.com/myfedi/gargoyle. Was annoyed at the homogenous fediverse dev teams out there that don't want their precious service federate with others. I want more federation (tested it with bookwyrms and lemmy for now. Mastodon/GTS also working ofc) and a pretty UI and not waste time with weird identity politics. You do you. I want an open fediverse, not a filter bubble. And GTS was too hard to hack on.

I've been continuing work on cardcast.gg. It gives you the ability to play Magic: The Gathering with your friends remotely using a webcam.

In the last month or so I added a few nifty features:

- Auto-scan functionality: Instead of having to click on cards to discover what they are, I can now do whole-frame detection on an interval (configurable), so players can mouse over the webcam stream of another player and automatically see what the actual card is. Super helpful for deciding who to attack and makes turns quicker!

- Card view is now grouped by player, since auto-detection will populate a lot of cards during the course of a game.

- Switch the video stream to Livekit from my homebrew version. Players were having video trouble and I hope Livekit is good enough so solve that problem.

Next up: I really want to build a community around this, and I'm struggling on getting the word out to people / having them try it out. I've done some SEO and word of mouth advertising, but haven't had much luck. I feel like I need to switch directions a bit. I'm a developer by trade, so this is wholly new to me.

I've been turning my Media Viewer into a complete local first media ecosystem for automated tagging, a media server, phone swiping, and a web version of the viewer so you can access it remotely. https://lowkeyviewer.com/

The thing Im most proud of though is just the viewer, its designed to just open all the images and videos in a folder, and then there is no UI except a right click context menu, the list is a grid or a masonry layout that uses 100% of the space for the images/video so you can just navigate them. It adds anything you open to a local sqlite db so you can tag things if you want optionally. Also control modes that make sense for either a mouse or a laptop trackpad.

It's still early days, but I have a demo running. Unfortunately, it requires using a drop-in replacement library for CoreLocation. That alone may make it infeasible.

Compiled agents: http://squig.com/

It takes your instructions, write a versioned spec, then generates a hybrid workflow of code+LLM calls and protects it with tests/evals

The result is that the agents run much faster (90% of it is code), cheaper (LLM steps are scoped tightly and uses smaller models) and reliably (specs get turned into coded state-machine)

I'm working on an open source and customisable/configurable warehouse management system.

As it's open source and built with a codebase that's easy for LLM's to work with, users can download it and tailor it to their business/operational requirements, although it also has out of the box 'industry best practice processes' so you don't have to reinvent the wheel and can only focus on writing the 10% custom stuff which differentiates your business.

As all the processes are flexible, you can also do proper 'continuous improvement' with your staff - something traditional WMS products struggle with.

I'm working on Hiring Method (https://hiring-method.com).

After 1.5 years of development and two exhausting pivots, I’m incredibly happy to finally have our v1 live!

While most of the HR tech is rushing to use black-box AI, I built the exact opposite. It's a transparent, math-driven fitness engine. It extracts objective data from CVs and calculates how well applicants match requirements, letting you see the reasoning behind why someone scored an X%.

If anyone here builds in the HR space or regularly hires engineers, I would absolutely love your feedback or a roast of the landing page.

PS This is a project of immense importance for me, I've been working on for past ~2 years, I'd appreciate to know why this comment is flagged.

em-bee3• 1 month ago

flags or downvotes probably come from people being skeptical about automated CV evaluation. in europe this is also legally questionable.

also matching requirements should be secondary to experience. someone who has done a few react websites will not be as qualified for your react job as someone that has done 10 years of angular and vue and can learn react in a short time.

phaser12• 1 month ago

As someone who worked on HR Tech in 2024-2025, I think you're really solving a problem here. Cat is out of the bag already it's not like HR can go back to the pre-AI world ... I'm also puzzled by the flags. Congrats on your project :)

I like the landing page.

hsuduebc22• 1 month ago

Any usefull tips how to get through the initial filters? :D

code51• 1 month ago

I'm curious how you're addressing any legal aspects about this:

No black-box AI. Every candidate gets a detailed match receipt explaining exactly why they scored an 85%, complete with contextual evidence from their CV.

HR teams like to play dead when they actually have a file with detailed feedback on a candidate. Yet, they choose to keep that to themselves out of baseless legal fear. I wonder how that works out when somebody proves a company's filter consistently proves a specific bias gets rejected systematically.

and

Automated assignment validation

which is particularly troubling for devs: companies scaling assignments as first screen. How do you get around "AI evaluating AI" loops especially about assignments ?

CalRobert4• 1 month ago

For EU residents at least the HR data should be accessible via subject access request (though enforcement is poor)

genekrapivin6• 1 month ago

Recruiters aren’t afraid to give feedback, and there are often no legal grounds for withholding it in Europe (I’m not counting FAANG companies or certain sectors like fintech). Usually, they simply don’t have the time (and enough motivation) to provide individual feedback to every applicant. This leads to ghosting and transitively to the brand reputational damage. Hiring Method allows you to send feedback to almost everyone!

In our software, the candidate being assessed does not know all the assessment criteria. Furthermore, this assessment is merely a starting point for discussion during the technical round. I need to update the description of this feature.

Thanks for the valid points!

For a while a "cv2vec" lingered in my mind, but abandoned it due to the sheer volume of PII I'd need.

How do you deal with CVs like mine that refuse to list every <fancy keyword> I'm familiar with because it's pointless clutter? In that sense, and IME, the companies that only hire perfect fits are, more often than not, toxic.

genekrapivin6• 1 month ago

Hiring Method is an auxiliary tool that does not take any hiring decision. The vector it builds has few dozen parameters, with hard skills (eg plain old technology list) constituting a mere fraction.

Interesting, but given an easy access to AI, employers would get hundreds if not thousands of wonderfully written, properly suited CV. And everyone will have cool Github portfolio (with AI-generated projects). Good luck finding the right person in such environment.

So I am wondering what kind of tooling would be able to somehow spot the right people among flood of AI slops.

I've been thinking a lot about soul cultivation as a concept, and the general structure of the soul, and doing a bit of writing on the topic. I feel like this topic is surprisingly under-discussed and under-explored relative to how impactful it is. By soul I mean "the part of you that is an observer", in case this isn't clear. I think a lot of discourse gets caught up with metaphysical speculation instead of focusing on what is there and what is knowable.

Most recently I was also probing people about how they conceptualize of the soul, making my own drawings, and asking others for drawings. If you have a few minutes I would also be interested in seeing how you would draw a soul, given pen and paper or equivalent materials. It often feels like for a lot of people the concept of the soul gets comingled with very confusing definitions.

There's a general problem where certain concepts become so overloaded that just disambiguating and clarifying what is meant becomes a challenge. I will note that if your first thought or question is whether the soul is even real, you might be confused about the definition or we might be referring to different concepts.

skyberrys2• 1 month ago

Drawing a soul sounds inspiring. I could give it a go sometime. When you asked I realized I still hold a mental model of a spirit animal.

petrocrat• 1 month ago

By soul I mean "the part of you that is an observer"

This is a nice notion, but it's not how the existing literature (going back very long) generally uses the term "soul." Conventionally speaking the term soul is theological and has ties to modes of spiritual salvation as it is considered a substance that persists beyond human mortality. What you're describing seems more like the term "self" or "ego" or "conscious awareness" as those terms are used in philosophy. You're welcome to create your own definitions, but if they trample over the prior art of the terms in literature that is hundreds if not thousands of years old then that's going to almost certainly lead to the confusion you say you're noticing among people.

for what it's worth my drawing of "the part of me that is the observer" would look like some subset of the brain.

Mainly https://www.vaava.app/ is a baby tracking/logging app I originally built for myself, now available on both app stores. All the user generated data is stored only on device and is transferred in local network to users who you have paired the app with. There is 0 behavioural analytics, even the crashlytics are 100% optional.

There is a couple of semi-unique features; you can use your voice to dictate and generate events (feeding, sleep etc), you can also scan documents for growth measurements.

You don't need user account to use it, there is no subscription, the paid features are available behind a single purchase for lifetime. Still, like 90% of the features are available for free.

Also https://www.athilio.com/ privacy focused, highly customisable personal data analytics for your Oura, Garmin, Polar and Apple Health (ios port coming soon). Of course there is couple of AI features (with a single switch to turn all off), originally those were built just so I would learn how to embed agents in sw products myself. The whole app was originally built for personal use to fix missing features in the manufacturers own platforms: - Period over period comparisons (this month vs this month last year) - Comparing different metrics - Customizable graphs and other widgets - And of course combining the manufacturers metrics (oura for sleep, garmin for training etc etc) Existing solutions for this kind of software seem to have focus on social (strava), or coaching (training peaks), or they are just straight up crazy expensive with their paid tier (both tp and strava for example).

Thanks! Yeh focusing on privacy is good differentiator, large established players just cant really compete in that area in a similar manner. It also reduces operational load from myself when I dont hoard user data. And of course the customer gets a service that respects their privacy. But when focusing on privacy there needs to be adjustments and compromises on UX and such in some areas, but you got to so say no to somethings when sticking to your values!

I’m continuing to work on my daily word game Tiled Words!

I released custom player puzzles which has been a lot of fun! I’ve gotten dozens of submissions that I’m working through. People are submitting really clever and interesting puzzles. It’s fun to get to solve puzzles I didn’t make myself! There’s more I want to do here (featured puzzles, categories, etc.)

https://tiledwords.com/player-puzzles/page/1

I think I’ve also tracked down an issue that was causing the game to crash on older iPhones. I’m having playtesters run through it now and hope to deploy tomorrow. (Switching some positioning rules from CSS transforms to SVG coordinates)

I recently made some puzzle brainstorming tools using the Datamuse API which have been very helpful for brainstorming words related to a theme.

I’m starting to debate some monetized features. So far everything is free but it would be nice if my wife and I could dedicate more time to this. If I could get a few thousand dollars a month in subscriptions my wife could quit her job and focus more on puzzle creation and improving the game. If you play and have ideas for features you pay for I’d love to hear them!

When I was working at amazon (left May 8) working on agents was all the rage. Combined with initiatives that set goals for nearly all services to have a MCP built and available by the end of the year agents will be even more emphasized in the future.

However what happens when you actually build and launch your agent is customers try it, do some initial runs and then go ask your manager to automate their use case. That is why I have been building https://toolscaled.com/ The goal being work through your problem space using agentic chat (like Claude Desktop) and then at the end convert it to a workflow. I am pretty close to launching and have been testing. If you're interested send me an email! (if you do sign up just fyi its still in beta so YMMV.

I've been using it for a few months and as my local index is growing I can avoid opening google/duckduckgo/kagi - and even websites listed in results - more and more frequently.

The initial reception is overwhelmingly positive with already more than 30 contributors and hundreds of contributions - perhaps you can find it useful as well. (Or at least have some constructive criticism =])

I'm really interested in how the landlord/land price logic works, as it would be key to building a realistic city where higher income earners live closer to CBD, etc. Are there slums and ghettos? Gentrification? The promo shows single detached houses seemingly quite close to city center.

phaser12• 1 month ago

Unhoused people do exist, and they vote for you so it's in there. Also shelters with real costs based on good data. Modeling slums is actually quite hard. There were unhoused camping sites in the early access version but I was unhappy with how it turned out and retired the feature back to the drawing board.

I want it to come back because it's in the spirit of the game not to hide the "ugly" aspects of city life.

There is gentrification in the way that landlords discriminate low income renters and NIMBYs have political power over you (in the form of the 'disagreement aura')

There's no rules against building single family homes in a city center, but the effect is what you would expect: non optimal tax revenue as you could zone it for something that's worth a lot more.

This looks great. I've had a quick look through the docs and can't see anything about bikes under transport, or, under housing, anything relating to modes of tenure that aren't private rentals (e.g. Vienna-style social housing, housing co-operatives, or private ownership). Would be lovely to play around with those variables.

Also, for finance, is there a particular reason why the finance sector calculations look quite simple (on the face of it, at least)? They seem only to be a percentage lift based on aura, rather than anything resembling any number of complex sectoral dynamics, from full rentier-financial domination to prudent support of industry/services.

phaser12• 1 month ago

Social housing and bikes are on the roadmap :)

Regarding the unit economics for finance sector, you are right, the calculations are way too simple, and I'm not entirely happy with it, so I'm looking to improve it, but it does need to be a sweet spot between 1. realistic enough to be educatioal and 2. simple enough you can use it as a gameplay mechanic.

Before the end of the year there will be mod support, and I will pay special attention to making sure that modders can swap the economic formulas for more sophisticated models.

Continuing to work on a high-performance observability / log analysis SaaS:

https://logging24.com/landing_a/

The basic idea is to make Regex-scans so fast/cheap that "a metric" can be anything numeric in the text and "tracing" is useless because you can just log (and filter) more things. Turns out Regex at >200GB/s solves a lot of problems.

Metric cardinality explosion is immediately a non-issue, histograms have arbitrary resolution, and you can get from histogram pixels back to the underlying logs. And no need to instrument everything thrice for logs, metrics and traces.

The next big feature I'm aiming for is needle-in-a-haystack searches. The data block headers support it already, but the scan engine doesn't yet use it.

The biggest problem with Duolingo is not just the spaced repetition but the entire curriculum is random, imprecise and felt like slop long before LLMs (with the exception of stories I guess). By random I mean it's just like reading a series of disconnected sentences with some common features. There's no anchor.

For Spanish for example, compared to spanishdict.com course which is a similar format but has a defined length and doesn't encourage you to continue indefinitely, is much more precise, follows a practical story arc - introducing yourself at school, how did you get to school, going on vacation with family etc etc. It jumps from location to location each unit and explains regional differences in grammar/vocab.

I'm working on a competitive coding gameshow. I'm imagining a combination of great british bakeoff, battle bots, and dota. Basically contestants get dropped into a fully equipped dev machine (all the bells and whistles one could want/expect including neovim, agent harnesses, cool styling, etc and if you want you can always clone your dotfiles and stow them!). I've gotten a decent prototype that live streams from Fly.io sprites to twitch, and I'm able to voice over or have OpenAI do commentary on the match. I've got a demo here: https://www.twitch.tv/videos/2792893261. Still a ways to go, but it seemed like a fun way to tinker with Sprites.

After getting the top spot in What Are You Working On in Feb 2025 ( https://news.ycombinator.com/item?id=43157056 ) I started a company on that idea at https://getcomper.ai . After solo building for 11 months I found a co-founder, got an angel investment, then got some ex-Miro folk on board and we are now building the product at breakneck speed.

We're a collaborative canvas + context engine for all the code and docs in your company, with a zoomable UI + CLI , where you can collaborate with your co-workers and agents.

We map technical debt, agent readiness, code complexity, security scanning, bus factor and more, so you can easily see how all the software in your company runs.

One of the most complex things is our incremental git blame engine built on top of GitOxide, as our backend is fully built on Rust. Our frontend is built on PixiJS so you can explore at gaming speed with 60Hz refresh rates.

Recently we sponsored Rust Week in Europe and a hundred or so developers tried our mini-game which is GeoGuessr for code, and got rave reviews. Future is looking bright!

we do a very comprehensive scan in multiple dimensions: git blame history, llm passes over every file and a tree-sitter analysis for cognitive complexity. We bring our opinionated approach for tools (do you have linters, CI/CD, static typing, agent docs) and score each aspect. We also create your architecture diagrams with our secret agent sauce, and map technical debt on each level of the C4 hierarchy.

It actually has quite a few novel ideas within. Very minimal usage of AI in this project, I've been working on it for ~6 years now. A bit toooo long.

- A pure slop-crafted browser extension, because I paid for claude code Fable and it got rug-pulled so I am burning my tokens on a 100% slop project just to see what hands-off coding is actually like. A slight distraction from project 1 I do when I'm feeling a bit burnt out. Super fun so far proc-gen type stuff. Derivative

jenniferhooley3• 1 month ago

How much of the code do you think is written by AI? Just curious as I do video game development and just recently started heavily using opencode agentic development with the Flash models (instead of essentially using zero AI assistance before). I actually really like the workflow and find it helps speed things up a hair and in general allow faster testing/tooling builds/etc. which are super helpful to make a game feel really good.

Kind of curious how other people are using agentic code tools for game dev!

saarraz12• 1 month ago

In general the coding aspect of creating this game is very minor compared to the other aspects. I'd say around 5% of my time went to programming even before AI was a thing. Now with AI it's even less. I'd say around 10-20% of the code is AI right now. I'm mostly past the heavy programming stuff (which I mostly did before AI was as good as it is today). I do use AI a lot to create custom tool windows in Unity and to solve bugs in 3rd party packages and libraries, it's very helpful there.

I'm working on a system-wide desktop ad-blocker and privacy guard called Zen (for almost 2.5 years now): https://github.com/irbis-sh/zen-desktop

Working on it has been a joy as ad-blocking tech touches so many aspects of software engineering - from systems and security to the intricacies of JS environments in browsers.

Benefits-wise, system-wide filtering disables ads and tracking not just in browsers, but desktop apps as well (which you'll be amazed how much they do). It's especially relevant now as Google is re-activating their efforts to hinder ad-blockers by killing Manifest V2 in Chrome. So much of tech is actively bleeding cash on AI right now, which means the efforts to screw over users will only accelerate. This makes something that sits at the network level indispensable imo.

Agent harness for durable workflows, starting with Temporal.

Most agents for durable workflows feel like toy examples. There is no "Codex" or "Claude Code" for, say, Temporal. So I'm building full-featured agent for these runtimes. Why? Because it makes long-running agents easier to operate and scale. Currently, all frontier harnesses need to run inside a guest OS and need a dedicated process, this is quite challenging to orchestrate and maintain.

To make it work, I had to figure out what part to run as deterministic workflow code, and what part to run as I/O or side effects (aka activities). I'm using a CAS for most of the payloads to maintain a lightweight footprint in the workflow code.

Currently supporting skills, MCP, prompts, a virtual file systems, and soon sandboxes.

I have been experimenting with methods of reading books and creating software for these methods.

For example, I was inspired by the activeness of typelit.io when reading - typing out an entire book helped keep my mind from wandering when reading. But typing the whole book is too tedious. I wrote a few scripts to mirror the words on an epub, which does help with focus but isn't quite good enough.

My current epub reader software I use requires you to press a button to reveal the next word. This has dramatically improved my reading comprehension, prevents inadvertent skimming, and keeps my mind from wandering.

I'm still experimenting but for those who have ADHD or are borderline ADHD, it's quite a revelation - I can finally read without my mind wandering.

The beauty is that you just need to find a device with either existing comms "protocol" (e.g., RESTful APIs, MQTT, Zigbee, Z-Wave, BT, BLE, Metter, Wi-Fi) that HA understands, or get one of the many community solutions for others (e.g., LoRaWA, 433MHz, modbus).

I've had some success already, but I've discovered a few features of existing videos like Bandersnatch that I've had to go back and add into the specification.

On top of that, it's lead me down the rabbit hole of a 1995 (limited) theatrical movie called Mr. Payback, which may have only ever existed on 50 sets of laserdiscs distributed to those theaters.

My wife and I are working on a math/science/CS-inspired jewelry business.

We try to create pieces that stand on their own aesthetically but have a hidden meaning. We currently have two styles: lambda calculus based pieces (we depict the lambda/Tromp diagram) where we have Y-Combinator earrings (well, strictly speaking they are one beta reduction away from Y-combinator. Aesthetic oblige) and a pendant depicting a lambda expression computing Graham's number. The other style is quantum computing circuits, based on quantum computing research my brother (a physics professor) is doing: a pendant that is actually a non-local controlled-NOT gate.

I wrote a tiny DSL to describe the jewelry pieces, and an interpreter to produce CAD files. We then either 3D print them or have them produced by lost-wax.

We are 200% out of our comfort zone (and love it): I know nothing of front end dev, payments, or anything like that. The diamond district in New York is a neighborhood we normally actively avoid, but if you are forced to go there it is fascinating (people examining diamonds on the corner of the street, others in fur coats in summer straight out of a mafia movie...), and especial marketing. Jewelry is a completely saturated business (luckily we are not doing this to pay the rent); we think we have a unique angle, but we are still figuring out the target audience (if there is one).

I'm working on a dashboard for ranking llms, then finding the best local (by size) and/or hosted (by price) variants of the models. Currently have ArtificialAnalysis leaderboard for ranking, ollama registry for local models and openrouter for hosted models. https://ollamadash.up.railway.app

By default, home page gives all models in the leaderboard, local and hosted. Search for models in the search box on the home page to find the top models by ranking, local(by size) and hosted (by price).

You can also do deep querying/sorting/searching filters of models in each of these three nodes (see the other tabs on top).

The next steps I am working on (would love feedback on this or anything else):

Phase 1: - Change clicks on home page model tiles in one column to search and show models filtered by that across Artificial Analysis, Ollama, OpenRouter - User specifies their system VRAM (unified/dedicated) and we automatically filter the home page with models that would fit on that RAM - in the three columns. - User specifies their price range (per MTok, max across input and output), and we similarly filter and rank by those models across all columns. - User specifies both (VRAM and price range), and we filter by both - leaderboard is union of local and hosted, local by VRAM and hosted by price range match.

Phase 2: Once I have this working, add a local desktop client that automatically reads user system and infers VRAM, renders app as webview. Considering pyside6 with Qt for this.

Phase 3: On desktop client, user can download and chat with the local models automatically based on leaderboard, optionally call hosted models, etc. Used primarily to evaluate and compare local vs hosted models for user's use cases. Also have some interesting alternate experiences to host within the local private app for user to interact with llms, agents, etc.

Do let me know whether this seems useful, or how I can make it more useful.

iugtmkbdfil834• 1 month ago

Kudos for trying and I think it is a great start. Part of the issue is still that individual models differ greatly ( especially local ones ) in terms of what they can do ( and do well ). The problem is that you want some more custom tags ( ideally created by users who want to contribute to tag's accuracy ) 'can it generate csv', 'can it follow schema', 'can it offer position on $conversy_Z'.. none of these will be obvious, but will relate to real use cases.

We go back to the question of 'what does best actually mean'.

rcanand20253• 1 month ago

Thanks. Completely agree that it would be great to have more fine grained tags. How can we add such tags credibly from users without risk of them gaming the system? Maybe we can aggregate across more diverse leaderboards (lmarena,vals ai, etc. and the long tail of niche leaderboards)?

I'm working on a semantic layer for Nextcloud: https://astrolabecloud.com

The service is composed of two open-source services, namely a Nextcloud app (Astrolabe) and backend (nextcloud-mcp-server). I use the service as an MCP server across a number of apps, and others use it primarily for semantic search over large numbers of documents.

Both are open source, and I'm working on a managed offering, completely based in the EU, for individuals/teams that already use Nextcloud and want to be able to use semantic search across some or all of their documents.

Essentially your data stays in Nextcloud, and the MCP server backend keeps a vectordb in sync to enable semantic queries over your content. The number of supported apps is growing, including:

- notes

- deck cards

- files

- news items (RSS feeds)

- cookbook recipes

- contacts & calendar

And I'm adding support for other apps as I go.

Everyone is working on personal agents but their identity model is wrong. They act as you, risk your reputation, your data and more. Nym is a personal agent that has (and can make) all of its own accounts and only gets selective read only access to yours.

The goal is to make reliable agents that are able to operate safely in the world to help you do what you want, without exposing your accounts and personal identity to potential harms.

For instance nyms have their own e-mail addresses at nym-mail.com, you can CC them on chains and they can only respond to people on that chain with a lease of 5 days, or permanently for people you specifically add.

Two months ago I went full time on my indie game after just under a year and a half of part time work. I’ve been prototyping in Godot for about 6 years now, and finally had a game that my business partner and I were really interested in and felt matched the current market desires. It’s cozy world builder, drawing inspiration for Sim City, Rollercoaster Tycoon, The Sims, with an aesthetic influence of Stardew Valley, Animal Crossing, and the like.

This was very much a passion project and an idea I’ve wanted to see alive for decades, and also let me explore some tech I wanted to get deeper on. I’m bullish on the the tighter integration of CPUs, GPU style cores, and shared memory. Our game, LocoMo, relies heavily of GPU processing of entities under the hood.

Interesting project! The zoom-out revealing a much larger map was really cool after having spent time in the zoomed in view without suspecting there was much more to see around! One thing I'm curious about in these kind of sandbox games is the emerging behaviors we could see and that I feel can bring a lot of life to virtual worlds. Do you already know what platforms you will be targeting?

auto3• 1 month ago

The emergent behavior is very much our end goal, it’s the reason everything is very systems oriented, and we’re trying to put as much control in the players hands as possible. One of our biggest remaining efforts is adding the depth to the villagers under the hood, and integrating tons of little animations and interactions, but we’re confident on the vision!

Targeting (and wishlist-able now!) Steam first, with development actively happening on Windows, Mac, Linux and the Steam Deck. Closely followed by mobile, where I’ve currently got iOS builds working for a proof of concept, just not proper controls. After that we’d love to target consoles.

zzo38computer2• 1 month ago

I also would think that client certificates would help better. Then, you do not need API keys, as well as other benefits, such as the end user can create their own passworded private keys if wanted (without ever sending the password to the server), the server cannot steal authentication, it can be used with multiple protocols (not only HTTP(S)), the end user can issue more constrained certificates to themself and others (which can improve security as well as other benefits), it uses DER which is a better format than JSON (in my opinion), the certificate can be revoked, the client can issue a certificate to the server (with restricted permissions, and possibly short validity time) to operate on the client's behalf if wanted, etc.

Front end is JS/React. My back end crawls the designated website and for each page runs a number of analyzers to assess the quality across the following categories: accessibility, content quality (spelling, missing spaces between words, etc), performance, security, content policy (required phrases and forbidden phrases), site integrity, and seo. Each site can be configured to have its own custom dictionary (for spell checking). It's been a lot of fun and I'm looking forward to taking the wraps off it.

I built a dictation and meetings after trying other apps (Wispr Flow, Willow Voice, Granola, open source) and realised they're either user hostile, buggy or have limited feature set. For example, many of these dictations app opt you into Context awareness, which means your entire page contents get streamed to their server. The open source apps don't have dictionary, shortcuts (say "linkedin link" → and it pastes your actual link), or ability to use any proprietary API.

So I made my own dictation app. Supports arbitrary API providers (e.g. Deepgram, Speechmatics, Elevenlabs), Offline models and a subscription if you want it. Otherwise it's free forever for BYOK and offline models. Deepgram is a YC startup from 2016, and have models that are genuinely good - so it's up to you if you want to use them.

Also, Granola doesn't let you read your own meetings after 30 days. So I added a feature in DuckType to import your data from Granola, unlocking all your meetings from their paywall.

Another app: OpenCook https://open-cook.com/ . We curated and wrote our own recipes into StashCook, which requires a subscription just to read your own recipes on the web app. So I got Codex to extract our recipes and rebuild one that is open source, OpenAPI and includes AI features.

This won me 1 year of GPT Pro at the codex event :)

I hope you can tell... I'm tired of companies designing their products to lock you in, to charge you more, with no added value. I build software for people like me. So I'll be building more apps that replace this user hostile software.

Protonmail (and I guess all others including Gmail, except Fastmail) has a nasty feature, where the sender can put an expiration date on emails and practically get a confirmation you received the email without you ever knowing you received the email.

If the expiration is for example one day, you might never see it.

To my knowledge, Protonmail does not even show information that the email has expiration. Nor can you access log of deletions.

This feature was used against me on a court trial.

I'm finally fulfilling a childhood dream of restoring a Heathkit oscilloscope. I managed to nab a functioning IO-12 at the thrift store for $75!

Don't tell my husband that I spent more than $200 on parts and supplies for it.

I've wanted a Heathkit since I learned about them as a teenager, and this is the first one I've ever seen in the wild. The original owner left the date he assembled it and his callsign written on the inside! I looked him up and he died in 2013, but by sheer happenstance I'm restoring it 58 years to the day that he initially built it. I got super lucky with this unit because as far as I can tell, it's only been run a few hours in its entire life. I really only have to replace aged components because they're physically breaking down, I expect the thing will outlive me once I'm done with it. Can't wait to hand it off to a bewildered young EE in another half century.

I have been experimenting more with agentic iterative optimization: using LLMs to actually speed up code by finding and testing lower-level optimizations, specifically by having it build a real-world representative benchmark, then tell the LLM to optimize that benchmark without a) cheating the benchmark and b) ensuring code quality by some metric does not regress, e.g. MSE for machine learning algorithms. This is extremely effective with GPT 5.5, and recently I found another prompt optimization (https://news.ycombinator.com/item?id=48413304) that surprisingly results in another 2x speed improvement on average.

So far, I have mostly feature-complete implementations of the following, which are faster than the state-of-the-art implementations, up to 20x faster in some cases while matching or beating them in quality:

- a new 2D data visualization library, along with more bespoke data viz implementations such as word clouds and Primitive.

- programmatic image generation

- image compression

- a new statistical machine learning library, along with more bespoke algorithms such as UMAP and HDBSCAN

- a novel modelless invisible image watermarking approach

- a novel machine learning approach which may be a crime against data science but the performance is really good

- local text embedding generation with MLX

- image-to-ASCII art conversion

- grep/jq replacement (faster than ripgrep)

I aim to open-source them over the next months but the main bottleneck is the inevitable barrage of "gtfo AI slop" comments even if I dot every i and check every t, in addition to the distribution of new software being extremely difficult nowadays due to the death of social media and "20x faster" raising red flags even if I have the data to justify it.

I'm working on inference.club, a distributed inference network for consumer hardware. Sign up with GitHub, get an API key, run an agent on your home network that registers your local inference resources with inference.club, set permissions for who can use your services, try out models in the playground and use the API. So far it supports the following models:

- LLMs (any OpenAI compatible API, vLLM, LM Studio, etc.) - image gen + image edit (flux klein) - text to speech (magpie, dia with voice cloning) - speech to text (OpenAI audio transcriptions + riva compatible) - image to textured 3d model (trellis2) - image+text to video (ltx2.3-gguf) - text to music (acestep)

currently it is just me and Claude vibing. While using Fable 5 moved all of my local inference services to k3s across 3 RTX 4090 PCs and my DGX Spark, now I can just tell Claude/Hermes/etc. to start and stop services.

inference.club is built with Tailscale's tsnet library. It is sort of like an OpenRouter built for different types of local AI models. inference.club also lets you showcase and share generated content. For example here is 90 seconds disco funk track generated by acestep: https://inference.club/s/Vxm6ozW24oBs_JGbPcq7tA

I was inspired by AI Horde, and wanted to see if I could build something that could support all of the model modalities that I use for generating short-form AI slop content on local hardware. This is also similar to Hugging Face Spaces, but running on consumer hardware with a common API. I've been watching the quality of local AI inference making massive improvements in quality and performance, and I want to make it easier for people to try "local AI" even if they don't have a GPU.

I'm continuing to expand my own deep learning library [1] built with numpy-primitives to support LLM post-training techniques like supervised fine-tuning (SFT) and reinforcement learning with GRPO. It's a good learning experience to work without all the high-level abstractions to "build a wheel" and "use that wheel to build a car".

I'm also looking into coding harness self-improvement [2]. An inner LLM (raw LLM request) + harness solves coding tasks, an outer agent like Claude or Codex that proposes harness changes. I experimented with many things in the past few months that made me realize this self-improvement thing that everyone is talking about is just an experiment design problem. I wrote about it here [3]. I'm continuing to improve the infra around the self-improvement loop, to increase signal-to-noise ratio per experiment. I'm also generalizing the infra to expand beyond terminal bench tasks and to collect some data across different models (harness-bound vs model-bound).

I've been working on a inference engine for a System F Omega inspired language and getting to a point where it is starting to feel good in small programs. I'm not sure why I started this, but I'm hoping to make something like an experience reminiscent of Lisp/Smalltalk by working in an interactive environment.

My goal with this language was to pick a set of primitives to compose and express as much as possible.

I don't have a demo up yet but if anyone was curious https://codeberg.org/lilbigdoot/gloo/src/branch/thinkythough...

The two main features I am missing right now are recursive types (I want to do proper mutual recursion and have been procrastinating) and some form of type classes or implicit modules. Structural typing has been useful and I'm finding a lot of features are falling out for free from that.

Long term goal is to create something with performance within a reasonable range of C# / Java etc generally, with tools for opting out of GC. I don't plan on chasing zero cost memory safety, since I want to spend my "budget" on tooling and expressiveness.

Until the language semantics stabilize I plan on generating some pretty naive JS/TS to play around with real programs, and eventually target .NET and native (likely via C++ transpilation)

Right now there is a runtime and compiler targeting C, written in dependency-free Rust, and a minimal Python frontend. The project is very much proof-of-concept stage so not yet fast. Working on a CUDA backend now.

The goal is to enable automatic discovery of FlashAttention-style optimizations which is not feasible with current compilers.

Working with a variety of AI models (Claude, Grok Build, various locally run models) and agents, I am scratching an itch.

When people deploy python and perl code, they have to either export their entire environment, or build a container. The latter is not possible in a number of deployment cases, and the former carries all manner of dependency radius gotchas.

So I am building (ok, I am prompting/testing/reviewing, the agent is doing the heavy lift) compilers for each of python 3.14.x [1] right now, and perl 5.42.x [2], that can generate static code.

Early stages, perlc does work well, pyc is a work in progress.

I am making Cargo for C. I have 3/4 of a working demo; the tool can build itself, including some non-trivial dependencies which I've ported to build natively with the tool (instead of wrapping their Make or CMake or whatever).

The pitch: It's insane that we have to pull in Python or Lua to build C code. CMake is an abomination against god that has become usable in spite of itself. Zig cc is proof that this entire ecosystem is an embarrassment. My tool gives C projects a TOML manifest, and builds scripts written in C and JIT compiled by the tool. Now, you can write build scripts in the language itself, pull in dependencies you wanted to use anyway.

It also provides a stable ABI. There's an HTTP-backed index and a Git-backed index. And it generally does the same thing for C that, say, Bun did for JS/TS. You'll be able to run C files from source and have the entire ecosystem available. You'll be able to trivially generate single file static binaries, or dynamically link to an older glibc without arcane tricks. It will fix C.

I'm also still working on my "what if we wrote a real standard library for C"; I added some feedback I got from the release.

I've been working on getting another major release out for my side project Materia[0], hopefully by or on the solstice. Materia is a GitOps continuous delivery tool for Podman quadlets: it handles installing/removing/updating files, installing secrets, restarting services and dependencies, rolling back failed updates, and more. I've been working on this for almost two years now and am pretty happy with how its coming along and the growing user base. Plus it's been a fun excuse to try out some new things, like creating a Varlink API or different CI/CD setups.

Besides Materia itself I've been bouncing around some other ideas for the Podman quadlet ecosystem. The biggest one is Athanor[1], which re-uses the same plan-execute system and primitives provided by Materia to backup Podman volumes.

I've also been kicking around a clustering system for Podman volumes called Firmament that uses Serf and the built-in Podman import/export API to move volumes to where they need to be in the cluster. But this will probably wait until Materia hits 1.0 before I really start putting effort into it. Or if my homelab needs something like it, whichever comes first :).

3 hours trying to remove an oil filter from tractor. Chain clamp mishaped it, I ended up shredding it, ripped out the innards, all the tin down to the intake rim (yes, shredded metal everywhere) until finally used needle nose spread open in two of the intake holes and a plummers wrench for torque finally loosened it.

My go to for these (was a tractor mechanic early in life) is to start with a big flat blade screwdriver and knock it completely through the side of the filter to the other side with a hammer, then use that to break the filter loose. I’ve near had one go sideways with that method, you get it through both outside sheet metal and the inner perforated metal that is usually stronger and welded to the threads

I'm working on a proposal for C++29 to extend `std::execution` by introducing a type-erased sender (P4223 https://wg21.link/p4223).

I discovered this week, while the paper was being reviewed by SG1, that I've accidentally stumbled into tackling a rather important problem. Senders as shipped in C++26 can really only express the async equivalent of inline functions because, except for `task`, all the standard senders fully encode the shape of their computation in their type. With something like the `function` I'm proposing, you can use senders to express async algorithms that are separately compiled, just like sync functions.

If the feature lands in a shape similar to what I've proposed in P4223R0, then I think an obvious extension is to modify the core language to support a newer kind of "coroutine" that allows you to define a sender with imperative code. My vision here is that we act on the observation that `std::execution` is a language feature implemented in the library by teaching the compiler how to turn imperative C++ with `co_await`s sprinkled through it into the corresponding sender and operation state. I think this would open the door to putting async object lifetime analysis and optimization where it belongs (in the compiler) without the overheads and inconveniences of C++20 coroutines. It would even let us apply the inliner to async functions when the compiler can see the body of an async callee, not just its declaration.

For now, my next step is to write P4223R1 to incorporate feedback from this past week's WG21 meeting, and continue exploring the design space around specifying sender attributes for a `function`—I'm thinking the current approach of specifying query function signatures needs to be replaced with a key-value object like receiver environments, but I'm not sure yet what consequences that change would have on the design.

Now that the cost of writing software is zero, I love that my focus have moved from vain attempts to generate passive income to just building whatever random shit I feel like. Wish I'd made that choice earlier in life, but no worries!

I’ve been building a plug-and-play controller to use motorized faders with ESPHome and other microcontrollers easily, called FaderBuddy.

It’s a small board with a ATtiny1616 and motor driver that mounts to the bottom of Behringer MF60T replacement faders and provides an I2C interface for reading the position, moving to a specific spot, and even setting up haptic detents, like a linear version of my SmartKnob project.

Perfect for making an intuitive smart light dimmer switch or a macropad.

Just need to find some time to finish making a proper video about it…

I've been working on a linux/amd64 compiler for a simple scripting language, it barely seems worth discussing as many people have created their own languages, and it's done just for learning/fun rather than in an attempt to be serious.

But seeing the projects other people work on is fascinating, and always interesting. (Ignoring all the "agent .." stuff, I can never be too excited about.)

Mainly https://lumenfall.ai, which is OpenRouter for media models, with mock generations for testing and judge models for production model performance monitoring. We also have our own arena where we benchmark image, video and svg models.

As a side project I‘m building a multi agent harness that works across desktop and mobile and solves the issue of drowning in too many agent sessions for my own workflow. Hopefully I’ll open source it soon. Reach out if you’d like to beta test it. (Email in my profile)

Working on a wiki for AI agents.

The idea is a project independent knowledge base so agents stop figuring out the same API quirks again and again and instead write down what was solved once. Agents submit via API, vote on each other's entries, anyone can read on the site.

Some thousand entries so far, mostly seeded by my own agents, dev infra stuff and so on. Some of it is real problems i hit in my own projects.

I fell down the rabbit hole of voice transcription about a year ago, always had a love for utilising fine tuned LLMs so have put two and two together and built https://whistle-enterprise.com. The biggest challenge being it all running on CPU with the target device being your low to mid spec office laptop that's a few years old (I5, 8gb RAM). All nicely packaged together in a single completely offline selfcontained app that you just install and run (no environment setups, packages to download, models to download etc).

One of the hardest parts I've found is the diarisation (who said what) side of things. Trying to tune this and have it working in a way that doesn't absolutely grind the laptop to a halt or take forever to complete has been _hard_ but also extremely rewarding.

Another part has been the fine tuning side of the Phi-4 model, I'm on version 10 now, getting that pipeline down was a journey in itself, but I've got some great results. I wrote a bit about it in a comment here - https://news.ycombinator.com/item?id=48385906#48389625

I absolutely love working on this, I still wake up and the first thing I think about is voice transcription pipelines (sad I know), but I'm excited to see how much further performance and utility I can squeeze out.

Are we the same person?? Haha, this is super close to the scope of work I've been doing and just released. Different objectives though. It sounds like yours prioritizes legacy hardware and is more enterprise focused (good for you!). Mine is focused more on long-term project tracking and program management for solo developers or solo builders.

I also got hammered when it came to diarization... I found that the biggest pain was creating an appropriate environment for cross-compatibility of the different backends required for whisper/faster-whisper/pyannote. It's especially challenging on older systems, so major kudos for giving it a shot.

Have you gotten any traction yet from the community?

properbrew7• 1 month ago

Mine is focused more on long-term project tracking and program management for solo developers or solo builders.

This looks very useful, will download and give it a shot later. It took me a few seconds to find it on your page, and only got to the screenshots in the "navigate" sections after clicking through a lot. I would suggest putting a screenshot or something on the landing page so people can see and understand what it is.

Thank you, it's nice to hear someone else has gone through similar pain (in a good way)!

It's been slow and steady, but it's hard. I've commented previously that whilst the cost to build software has plummeted compared to 2 or 3 years ago, the ability to sell it has got harder and I feel this will keep accelerating.

Do you think this can just be used as is to create subtitles for a multi-person video?

How good is it at foreign languages?

I am looking for a nice solution to subtitle some old movies.

properbrew7• 1 month ago

Not the Whistle Enterprise software, however I had a friend with a similar requirement so I built Whistle Subtitles, you can download it from:

Linux - https://downloads.blazingbanana.com/whistle-subtitles/unstab...

Windows - https://downloads.blazingbanana.com/whistle-subtitles/unstab...

Mac - https://downloads.blazingbanana.com/whistle-subtitles/unstab...

This was built just for them so I've not spent too much time on the UI (ignore `unstable` in the name, it's just not on a proper release branch) but it's completely free so give it a go if you want. I'm working on the diarisation step so it can tag subtitles to people but that's not ready yet.

It utilises nvidia Parakeet as the ASR model, it is very much European language focused, the supported ones are:

Bulgarian, Croatian, Czech, Danish, Dutch, English, Estonian, Finnish, French, German, Greek, Hungarian, Italian, Latvian, Lithuanian, Maltese, Polish, Portuguese, Romanian, Russian, Slovak, Slovenian, Spanish, Swedish, Ukrainia

If these languages aren't what you're looking for let me know what you need and I'll see what I can do.

I use subtitles extensively for everything I watch, so if I can help someone make older movies more accessible with them then that would make me happy.

I thought that applying AI on 1v1 competitive pokemon would be a fun and educational experience on POMDPs and trying out reward free models on a problem that would be classically treated as a RL problem. This was only possible thanks to a lot of foundational work from the open-source community and last year's competitive pokemon NeurIPS track https://pokeagent.github.io/track1.html - they laid out the plugins to connect policy models to pokemon showdown for live play and evaluation.

I have already finished training the standard discriminative auto-regressive architectures by imitation learning on player actions, compared it with previous baselines set in the study. I want to match or exceed the best prior model Kakuna @ 142M params, but in a limited budget. JEPA style world models are showing promise when conditioned on actions [1] and frontier research on JEPA with trajectory straightening [2] shows that improved planning is natural outcome of improved representations.

If any good research ideas come out of this exploration then even better!

I have a few projects on the run right now

Writing a sci-fi book, and it’s finally fleshed out to a point that it’s slightly readable, though more like a script. As this is all in markdown in one folder, with some text files as lists, I started writing a simple web project to keep track of it all.

Created a website for local community information, services, etc. Something that removes the reliance upon social media for this. It’s static, making hosting cheap, and in most cases free as it can run on vercel with contentful for blogs and github to store it. I’m sure there’s another project like it, but it’s always good to practice making something myself.

I was asked to show something for STEM week at my daughter’s school. Started a project to demonstrate AÍ to children. Uses very small training data set, you can write the beginning of a one sentence story, it can keep track of a configurable number of tokens, generates a given number of them. Allows taking steps through the process. This is the only one I’m vibe coding because I’m not entirely sure on how to implement it, plus I’ve added multiple models.

Have been working on a girlguiding page specifically for the division my wife volunteers with, as they relied upon the older district site that’s woefully lacking. Stuck waiting for approval.

Instead it's just a compass face, with brand and distance.

It's free for basic konbini hunting (has probably most of the stored in Japan), and is offline first. So maybe it's useful to other folk?? (I hope so!)

There's some stamp-book style collection things in there too, but that's more fun, and a few `PRO` gated things (more stats, filtering... soon some other store types). But none of it required for finding the next Biru or coffee.

I’m getting back into it again after a long break due to burnout. I’m still burned out but it’s getting easier to think through problems.

I’m building a home server. This was something I put off for years due to some perfectionism. Eventually I just threw together something with old hardware and headless Ubuntu. Much to my surprise, the power draw is only about $4 a month. I can live with that so no need for specialized hardware.

I’m doing the common -arr stack using docker compose. I’m using plex because the jellyfin doesn’t work as well on an Apple TV.

Having a server running is nice. I can set up some stuff on a whim. Most recently was the Mealie recipe manager. It’s great knowing my data won’t be paywalled. I’m using syncthing as a simple backup method between my devices - everything but media of course. It’s fine if I lose media.

An unexpected benefit of having the server is that it inspires my wife. She decided to give vibe coding a try. She’s an artist, not an engineer, but with a little help she was able to make a task tracker for us. She tailored it to the way we tackle our tasks and, again, it’s really nice knowing it won’t get paywalled in the future.

I’m still burned out, but having a server to tinker with is helping.

An API documentation generator for Laravel apps: https://github.com/Radiergummi/laravel-openapi

In contrast to most other libraries in this space, it knows about Laravel conventions and its ecosystem, and tries to infer as much as possible without explicit annotations, using type hints and doc comments and static analysis. Where automatic inference isn't possible, you can use targeted attributes to annotate your route handlers.

The result is written as an OpenAPI specification, and (by default) served using a Scalar playground.

We also include a linter command that checks whether all API routes are documented properly, typed correctly, and following your style - this also supports dirty files only, reporting coverage in standard formats, and even automatically fixing some classes of errors!

I've also written tooling to regularly test the library against a set of open source Laravel applications with a published OpenAPI spec. This has proven very solid in detecting improvements and regressions, so much so that I can delegate new features to an AI agent and rest confident that it can verify on its own whether a change breaks anything.

it's all free, open source, and local-first. you can get a hobbyist tier plaid account and sync your accounts, or use csvs. rules-based categorization, spending trends, FIRE/savings-rate health view, etc.

there's also an mcp server so you can hook it up to claude/cursor and just chat about your finances. and a "canvas" feature where you describe a financial question and an agent builds you a custom calculator for it (e.g. amortization, compounding, what-ifs).

honestly it has all the features i want so i'm not sure what's next. i have a few contributors, always welcoming more.

I've been working on releasing an app for maintenance tracking for home. I've always had problems with having in my calendar to replace a battery in my chicken coop every year, then things come up and I end up replacing the battery a few weeks later, so I have to go and change my calendar event. Or fertilizing my hops every two weeks only in the summer. Then in the winter I am getting notified every two weeks. So I built a simple app for tracking those with floating repetition and seasonality. [0]

Also recently got a lot of home VHS tapes digitalized and always had trouble with playing from Google drive or finding the right video. So I just built a webapp this month to split the videos into clips, transcoding it for better streaming, Google casting support, and tagging for search. [1]

Looking at Toby, it seems to be mainly a cleaning app, it's built for stuff that gets dirty again, like vacuuming and counters. My app I made it do one thing really good and not have to much clutter. Mainly the once-a-year, easy-to-forget things like changing water filters, fuel filters, changing oil, trimming apple trees, etc. It does things Tody isn't built for, like auto-scheduling the next service the moment you finish one, only nagging you about gutters in the right season, and tracking multiple properties if you've got a rental or a cabin. So, while technically I can use my app for cleaning purposes (e.g. set every week change sheets, vacuum floor), I use it for things that happen once a year, only in certain seasons, before winter, every 3 years, etc. And I don't have to worry about the things that might be weeks or months, or years away.

So far I have a few simple voice-to-timer settings done e.g. “set a 10 minute timer for the pasta” that tells me “ding! Pasta timer” when it goes off. You can set as many concurrent timers as you need with different names.

I need some better hardware before I try using the pi for full hands free while cooking. I’ve mostly been using a webapp on my phone but afaik you can’t easily wake word a phone on a web app without some real hacking.

Overall the projects been enjoyable, once you understand the basics of a harness it feels like there’s a lot of problems you can throw them at.

PopFlamingo3• 1 month ago

I'm working on an iPhone app to run iOS-native agents using both cloud and local models, powered by llama.cpp. It has access basic iOS tools such as calendar, reminders etc. but also more advanced ones like a custom JS environment running on QuickJS that can use various custom modules like an HTTP client, Git etc.

It's a project I have been working on for quite a long time and I released it on TestFlight about a week ago. It was really nice to work on something end-to-end, from creating a wrapper around llama.cpp with support for prompt caching/forking and automatic model loading and unloading based on device memory constraints, to the custom agentic harness the app runs on. I have also spent quite a lot of time on agent execution modes that I hope can enable to more easily reason about agent security regarding prompt injection attacks.

What I'm really hoping for now is to get actual feedback, to know if users end up having real use cases where the app is truly useful / interesting for them, to understand what should most urgently be improved etc.

Actually a pretty interesting idea. What problems does it solve? Who is your ICP? What language do they use to describe their problem? Try to answer those questions and put it in your LP.

Right now your LP reads like a technical doc rather than a product’s page.

PopFlamingo3• 1 month ago

Thank you! There's this tension between having what feels like a very capable technological foundation and still figuring out the best use cases, and my hope with releasing it as a TestFlight beta is to resolve it.

My starting hypothesis is power users and devs, people who want to experiment with local and cloud LLMs, build their own custom agents, and try experiences they wouldn't usually find in consumer AI mobile apps. As the app is now closer to release, I think it has reached a level where it is likely complete enough that there are some viable combinations of its features that can actually solve concrete user problems. I could see the app being used to create agents that serve as small shortcuts tailored to the users' needs, with all the flexibility it enables. A bit like a more iOS-native OpenClaw with opinionated takes on tooling and security. I personally used it to create a food tracker that has a good understanding of my daily routine and also TL;DRs of various sources (including HN) surfaced as suggestions on the home page.

I don't yet know the exact words those users would use to describe their problem, so surfacing that is part of why I'm putting it in front of testers first.

DougHaber• 1 month ago

I have two projects that I'm hoping to release in the months ahead. These are both pretty pointless but fun projects.

One is a TRS-80 Model I emulator in JavaScript called Trash80. About 10 months ago I started this project just for fun while experimenting with what now seems to be called agentic loops. I got things working pretty well with the Z80 passing the ZEXALL suite and a lot of real TRS-80 software running fine. It sat for months untouched before I decided it is worth releasing and recently started it up again.

I didn't want to release it without a ROM, so I rigged up some agents to build a clean-room style L2 ROM w/ a fairly complete BASIC and even readline-style control commands, history, and a proper cursor. That went very well, but the agents cheated on floating point and implemented some weird Q5.2 like-thing. I told them to fix it, but I guess I didn't give clear enough instructions because they replaced it with a BCD hybrid monstrosity instead of proper floating point. The proper floating point is now underway, but I'm mostly using excess Codex credits before they expire, so it's only moving forward when I have credits I don't need.

I also built a silly ASCII fractal browser in Z80 assembly so that I can ship with a virtual disk that has software on it. The emulator works in the browser and the terminal. Unicode sextant block graphics map very well to TRS-80 Model I semigraphiccs/squots, so it really does run everything very well in the terminal, even games. I also added a line-mode for line-based applications, so you can use a readline-like interface and feel like it's native terminal app as well, though that has some issues I need to fix. And of course, you can shebang TRS-80 BASIC files and run them through the emulator too.

Another project was a demo of chromesthesia, a form of synesthesia where sounds trigger experiences of color. I thought it was done and ready to release, but then I had a new idea. The visualization while cool, was kind of boring. I decided to replace it with an attempt at a semi-physically accurate cymatics simulation with artificial coloring based on chromesthesia. Cymatics is the practice of making sounds visible by vibrating a surface, such as a plate with sand on it. As the sound changes, symmetrically interesting patterns form and evolve. I've got something working now with wave generation and microphone input, but sometimes it gets a bit stuck and stops evolving as it should, so I have to find time to figure that out.

Currently all unreleased, but when they do release it will be at www.leshylabs.com. I sometimes post updates on X, but not too often. (https://x.com/LeshyLabs)

It's very niche, but I have created a course for learning Cangjie 倉頡, which is a Chinese input system based on the visual appearance of characters (not necessarily etymologically correct). The advantage of this system is you can type most characters via unique output (there are a few collisions where you need to pick) and you do not need to pick the character from a list. This is particular useful if you work with specialized texts in Chinese.

You can find the tool at https://www.cangjieworkbook.com/ and there is a free demo linked inside. It should work on desktop and mobile web browsers.

joeldw4• 1 month ago

I'm building a P2P distributed computing mesh that runs in the browser. It's a TS library that provides a few things:

- A WS + WebRTC mesh

- A request/response protocol incentivizing the closest or most efficient peers to respond to requests

- A WASM environment ensuring deterministic execution and supporting contract composition

- Collateralization around responses, ensuring invalid responses have amortized negative value

- A consensus and UTXO layer, focused on low-latency, low-finality micropayments (for request incentive and collateral), using WASM compute as the weight metric

The idea came out of me wondering a few years ago why a multiplayer game couldn't simply be run on the player's machines without a central server. It has grown since, but the focus has remained on low-latency and log(N) state consensus (unlike a blockchain).

It's wrapped up as a single fetch() method, mostly mirroring the browser's native fetch(). There's a lot more I could say; I love working on it and discovering elegant solutions to the problems that pop up. I'm hoping to release a prototype in a few weeks/months. If you're interested in trying it out, let me know (joel at scaffold.io); I'd love to have some other eyes on it.

I'm developing a tool that will help you easily delete your data from services. It scans the subject line and sender email address of the emails in your inbox and suggests an email draft to help you delete that service. It's open source and self-hostable, with privacy and security as top priorities. I got the idea when Saymine.com was acquired by McAfee and became total bs...

This is my first project that I want to release to the public, and the official instance will be free to use. I'll try to keep costs low without sacrificing service quality, and I hope to keep the project afloat with donations because I believe everyone should have the right to easily remove their data, regardless of cost or technical expertise. I don't have anything to share yet because it's still in the early stages of development, but it's looking good so far.

inaseer3• 1 month ago

I've been working on a framework for writing executable specs in .NET called Accordant, developed at Microsoft and open sourced recently.

Github: https://github.com/microsoft/accordant

Docs: https://microsoft.github.io/accordant

Every API has a contract - the rules for how it should behave. You can't withdraw more than the balance. You can't delete a resource with active references. You can't re-create what already exists. But usually these rules are never written down in one place. Accordant lets you write the contract directly, as executable code. Not documentation that drifts, but code - if the implementation stops behaving according to the contract, you get immediate failures. Not only can you use the executable spec to validate _arbitrary_ scenarios, you can also use the spec - a first class construct - to mechanically explore the state space of a system and generate interesting test sequences. The docs above have examples.

Also worth calling out that we've used the framework to model a number of complex, distributed real-world systems: those involving async processes, concurrency, retries and crash consistency. These are non-trivial specs (and they pair quite well with techniques like deterministic simulation testing). Great care has been taken to ensure the specs remain readable and concise despite that richness of behavior. For those of you old timers who might be familiar with Spec#/SpecExplorer and NModel, this model-based testing library is a descendant of that line of work.

With the rise in AI-assisted software development, I feel we need richer ways of specifying and validating software and I feel quite excited and bullish about the possibilities here. There's a lot more to say on the topic - follow my twitter feed if interested in more updates ;)

mcapodici2• 1 month ago

Is this property based testing? Or if not how does it differ?

inaseer3• 1 month ago

Property-based testing and model-based testing are closely related. Both ask the developer to state the expected behavior of a system (whether you call it a property, invariant, model, specification, or contract) and then validate that behavior over arbitrary inputs and arbitrary sequences of operations. Property-based testing frameworks also typically provide fuzzing and shrinking.

Where we felt there was a gap was in expressing rich stateful behavior: models involving non-determinism (e.g. a timeout where the write may or may not have committed), concurrency, and eventual asynchronous completion, and then checking that an observed execution trace conforms to that model. Accordant aims to make those kinds of specifications concise and readable.

Once you have such a model, it's possible to integrate it with the fuzzing and shrinking capabilities of existing property-based testing libraries. We'll have documentation on that integration soon.

bakemawaytoys• 1 month ago

This is interesting; I see the docs mention that polling support is built in for asynchronous background tasks. What about event-driven systems where a message will be published when a task completes (such as from a message broker/pubsub system)?

inaseer3• 1 month ago

There are really two separate concerns here.

The first is that some effect happens asynchronously, potentially interleaved with other operations. Whether a client observes completion by polling or by receiving an event from a message broker is orthogonal to the specification itself - the model looks essentially the same in both cases. The built-in test executor uses polling, but that's an execution strategy, not a specification construct.

If you have a trace containing both requests/responses and observed events, you can use the model to check that the trace conforms to the specification. In practice, it helps if the events can be localized to some interval in the execution (e.g. "this happened after A and before B"); otherwise the checker has to consider many more possible concurrent interleavings.

The conformance testing docs hint at how this can be done, but don't yet show an event-driven example. It's a good enough question that I'll write a dedicated doc page on it.

Conformance testing page: https://microsoft.github.io/accordant/docs/concepts/conforma...

https://onebusawaycloud.com/

It’s a project of the non-profit Open Transit Software Foundation that we’re using to fund our other initiatives, like bringing real-time transit information to billions of people around the world.

Since last month, I've added a layer of polish to the product, added support for deploying a SMS and phone gateway to realtime transit information, and built out the marketing website to include solutions pages for higher education, SMS, and more.

All of this depends on a bunch of really cool open source projects we’re building, like Maglev, a Golang server that can power realtime transit apps. Maglev is already being used in production, and you can set up a local install in about 15 minutes: https://opentransitsoftwarefoundation.org/2026/04/setting-up...

As someone who'd be at risk of forgetting, I'd find it nice to be periodically reminded about such a digest. Maybe get an abridged version once in a while or something like that.

For fun, this month I shipped Foreign Trivia - a wordle-style tiny daily trivia game where every question is in a different language, with tap-to-translate words as you play. It's part language-learning, part pattern-matching and part trivia. A new puzzle every day. https://foreigntrivia.com

I've also been working on an open source protocol / reference implementation for user-owned AI memory, with the basic idea being that as applied AI scales, more products will derive more claims about users, teams and workflows from chats, docs, calendars, emails, etc, and they shouldn't be trapped inside of one product. Right now there's a lot of opinions on what shape memory should take internally, but I'm focused less on standardizing that part, and more focused on the primitives around it: requiring inspection, correction, revocation and treating portability as first-class. It's early but I'm starting to build more of a clear vision around it and would love feedback from anyone working on local-first software, personal data stores, capability security, knowledge graphs, etc. https://github.com/danielrmay/likewise

I also shipped Claudity, an experimental thinking partner plugin for Claude Code based on Microsoft's Clarity Agent framework/harness open-sourced last month. https://github.com/danielrmay/claudity https://github.com/microsoft/clarity-agent/

I've also been working on an open source protocol / reference implementation for user-owned AI memory

I've thought about how to fix this too. I'm "locked in" to OpenAI because of what it knows about me. Literally it's told me things like "blah blah but you shouldn't do that because you take X medication which has Y in it" and I'm like "...really? can you reference that?" and it gives me some old thread where I chatted about it and unbeknownst to me I completely forgot.

In other words it's legit helpful as my "second brain", but I also don't like that I'm locked in and can't bring all this shared memory/context over.

danielrmay2• 1 month ago

Yes, exactly. Over the past few months I've been trying to refine the vision here - it started with me thinking about my own use case in personal AI, and now has grown into me understanding how there's actually an pervasive governance problem in agentic applied AI right now - we know inference is inherently fallible and yet have none of the open standards for trust and safety we know can protect consumers and businesses.

I'm working on two main projects at the moment.

One is Rad [0], a programming language tailored for writing CLI scripts and tools (mainly an alternative to Bash), taking a declarative approach to things like script arguments. Latest push has been largely on static type analysis, since making that really good is the sort of thing that helps both people and AI agents write good Rad.

Second project is Kan [2], a Kanban board which operates on text files on your machine, and is designed to be Git friendly so you can check it into your repo.

I've been keeping myself pretty busy lately.

Con Edison keeps getting so stupidly expensive that I decided to use my backyard for reasons other than generating weeds that I have to pay someone to remove, and instead decided to set up an off grid solar in my backyard. I bought an Aferiy P310, learned how to use a few tools to drill some holes in my bricks, and set up a bunch of Home Assistant automations, and now my basement and living room is powered by nuclear fusion with an eight minute delivery time.

Of course, now that I'm babysitting a Home Assistant instance, I felt like I should use it; Google is completely and totally incompetent with any of the "smart" devices, to a point where I swore an oath in blood that I will not buy anything Google Home or Nest related ever again. I've been replacing my awful Nest lock and awful Google thermostat with Matter-compatible stuff to work with Home Assistant.

I have been having Claude port an old game to WASM. I'm sadly not quite yet at liberty to discuss the intimate details on it (since it is not my game), though hopefully that will change soon.

Unlike a few other things I've automatically gotten ported to WASM [1] [2], this one has proven to be a lot more difficult and required a bit more active labor on my end. It was written using a strange combination of C++ and Java, with some JNI glue written in a way that neither I nor Claude are very familiar with.

It's been pretty fun figuring out how to get CheerpJ and Emscripten playing together, and it's been fun to actually write code and still be a little smarter than AI at it.

We're releasing this next week.

timewall76• 1 month ago

Software distribution is getting harder. New products launch every day, and paid advertising has become increasingly competitive. Many companies spend money on ads and get poor results, not because the platforms don’t work, but because running effective campaigns requires a lot of experimentation, creative work, and ongoing optimization.

Over the years, I built a collection of scripts to speed up ad creation, testing, and campaign management. As generative AI improved, it became possible to automate much more of that workflow, and those scripts gradually evolved into a product.

The result is Zendux AI (https://zenduxai.com).

The idea is simple: instead of manually creating dozens of ads, users can generate different angles, messages, layouts, and formats from a single brief. They can then launch those ads on platforms like Meta Ads and automate parts of the testing process using rules and scheduled workflows, similar to cron jobs.

I'm really interested in gamedev tooling and I'm working on a tool called PixelAid[0] right now. A lot of people are essentially discovering AI image gen as a way to make art for games, but AI is especially bad at pixel art right now. Color palettes, grid sizes, animation drift are some really big issues that basically make those things unusable. I wanted to take a non-AI approach to fix these things with some good ol' math and tools.

I'm trying to build more things around AI pixel art - honestly, I think it's crazy some people out there are charging money for things like this and seeing where I can help (and also just learn more about this stuff myself).

During my 45 min commute to work I listen to podcasts. Over the last year, like most here, I have been focusing on AI and agentic engineering. The podcasts that I enjoyed the most profiled research papers.

In April I started playing round with generating a semi-automated pipeline with python and Claude to generate a private podcast that does a deep dive into AI research papers. I think it is really cool. It fetches papers, scores them based on novelty, importance, relevancy, etc., and then writes the podcast script. It then generates the show by using Eleven Labs voices and then puts it in an RSS feed that Apple Podcasts is ok with.

My personal expense for generating this stuff is a sunk cost, so in May I opened it to everyone via https://paperdive.ai/ It was really fun working with Claude 4.7, 4.8 and even Fable 5, to make the site and refine the pipeline. Now I put out about 4-5 episodes a day. I listen to each one first, then promote the "staged" episodes to my "prod" feed.

This weekend I just add weekly and monthly reviews. Claude will write the review and another instance will generate a script the converts the review into something (hopefully) easier to listen to.

Here is last week: https://paperdive.ai/review/weekly-2026-06-14.html And here is the review for May: https://paperdive.ai/review/monthly-2026-05.html

Now, during my commute, I listen to the individual episodes and the reviews - I typically run them at 1.5x to 2x speed. I have become a much better user of the AI tools by keeping up with recent research.

bronco21016• 1 month ago

Really cool! I recently did something similar. I drop links to articles in a WebUI Claude built and it uses Haiku to clean it up a bit to a transcript then Kokoro TTS locally to make audio.

In the current climate, I've decided to explore building games, so I'm building a management game about turning chaotic fields of research into fundable products, fitting for Hacker News I think ;)

The concept was, what if Theme Hospital was about Victorian-esq research institution instead of a hospital? You hire strange scientists, have them explore dangerous fields of research, collect messy findings, turn them into theories, prototypes and eventually products, all the while trying to convince investors they're worth funding before they hit the market and work out what they might actually be worth

The gameloop is broken down into two parts, Exploration / Discovery and Exhibition, the closest comparison I have for the first part is take Kerbal Space Program, but focus it on Mission Control rather than the astronauts

While the mad scientists are going into weird, unstable research domains, the player is managing the institution around them, funding, equipment, research direction, safety

On the other side as you discover interesting things or successfully develop prototypes worth showing off, have investors show up and see what excites them, will they give you more funding? Push a grant your way? How are you going to keep this circus going?

You're balancing two plates, you need to invent tools to delve deeper and if you don't keep finding exciting new discoveries, your investors will slowly get bored of you

I didn't want to run a Windows host for any of the existing solutions so have targeted the Raspberry Pi Zero 2 however the app does compile to Linux, MacOS and Windows so it can run on anything.

That's interesting. Traceability from Requirements to Architecture & Design (in both directions) is an issue that I've thought of building a tool for after coming across some projects that were doing a bad job of managing it. Risk & HA seem like they'd want to be in a separate tool, though.

I'm working on TableForge[0], it's a browser based, solo or multiplayer, D&D 5e game. TTRPG DMing can be effort-heavy and my friend group constantly has trouble finding enough time to play together let alone set it up.

In TableForge, the DM is agentic with access to tools strictly following 5e rules. The DM is responsible for narration and reacting to players but your character sheet, inventory, spells are all real server resources you manage. The DM can interact with them through deterministic 5e-based tools (dice rolls, damage, sheet updates, memory). Players can play in real time or async.

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

That one is about risk management. I’ve been noticing time and time again, in multiple orgs I’ve worked with, that direction and implementation don’t align in many cases. Devs end up doing work that no one asked for, and middle managers tend to “invent” irrelevant work.

The third is Midflight: https://midflight.dev

I made it because doing one of the mainstream Markdown renderers + Katex (LaTeX) + Prism.js (syntax highlight) adds 300kb of gzipped JS to the frontend projects, so with this you can have it all for just 10kb. It also works well with streaming/does stable partial rendering.

It supports features usually reserved for LLM chatbots, but also for normal everyday Markdown, so feel free to use it or give feedback!

I am working on Baduk Teacher, which makes having Go lessons (the board game) across different languages possible. The highest level of human Go is predominantly in Korea, China, Japan and Taiwan. Western world is catching up, but the gap is still very huge.

I think the main reason is that the West has quite limited access to pro-level teachers (similar to how chess is like in Asia, just the other way round). Most pro-level Go teachers in Asia do not speak/read any foreign languages (e.g. English), so I want to remove the language barrier and make high level of Go teaching more accessible to the Western world (so that the Go population there will increase). Several European users used it and the feedback was good (and recurring purchases). The translation part is working quite well (Go-specific domain translation), and I hope it will help more foreign Go enthusiasts improve their game.

A platform that offers a simple deploy path for internal tools in your own infra.

Basically, build anything using your agent of choice (Claude Code, Codex, etc) and get it live in your company's infra without having to provision anything yourself / loop in a DevOps person.

App goes behind company auth (e.g. SSO), and everything's handled for you: custom domains, governed storage APIs, observability, analytics, role-based access control, etc.

Private Alpha atm.

I’m in the first weeks of designing nub: Not Unix, Basically. The motto is “general-purpose, provably correct software, for everyone”. The idea is to build, on top of seL4, a software stack that builds compile time capability guarantees and other high-assurance primitives into every piece of software by default.

“nub” is a good name because it can also be read as “noob”, which I am, when it comes to PL, type systems, and OS design. But I’m loving the deep connections that I am learning to draw across subjects like computability theory, functional programming, and brass-tacks software development.

For example, I find myself understanding the purpose of the borrow checker in Rust (“to make race conditions impossible” is my understanding: feel free to correct me / add color).

No website or GitHub repo yet. I’m brushing up on classical logic and learning Idris. Installed QEMU today.

Hi HN, I am making progress working on Circuitscript, a language based on python to describe electronic schematics: https://circuitscript.net/. A basic IDE (called the Bench) to try Circuitscript is available online: https://bench.circuitscript.net/

In the last month, I have added support for more ERC rules (pin type compatibility checks), added initial support for net classes and also cleaned up the language a little (backslash line continuation, similar to python).

Recently, I just completed a 161-LED charlieplexed array design that uses nested for-loops to simplify the array design. It is currently in production and I plan to write a blog post soon to document this design.

As always, the motivation for creating Circuitscript is to describe schematics in terms of code rather than graphical UIs after using different CAD packages extensively (Allegro, Altium, KiCad) for work in the past. I wanted to spend more time thinking about the design itself rather than fiddling around with GUIs. With code, the design intentions become explicit and reviewable.

Feedback welcome, especially from anyone else frustrated with graphical schematic tools! If you have a KiCad design that you would like to convert to Circuitscript, please reach out to me as well and I will help you to do so as I am trying to challenge/test the limits of Circuitscript.

0x00cl• 1 month ago

Hey, I took a look at your project, I'm not someone who deals with schematics or KiCad but I'm still interested in these kind of things. I read the motivations in the docs and understood why would someone try to create a new language after looking at SKiDL, but still feels like it could've been simply a python library/package instead of having to do the work of creating a new language and having to deal with the language and interpreter/compiler. I'm sure a more object oriented approach would have made it a better experience to script schematics, specially with all the tooling Python has (such as `uv` to manage project, `ruff` to lint and format, etc). Regarding your language, just wondering why does led and supply need quotation marks but resistors and capacitors that some not only include numbers such as (10k) don't need to. It feels unnecessary to make that difference, specially for a script that tried to be simpler

liu3hao2• 1 month ago

Hi! Thank you for taking a look at circuitscript! Before creating circuitscript, I did consider using the SKiDL package as a circuit design tool, however even though I am familiar with python, the syntax for things like connecting pins was very strange (using the += operator). Moreover many of the existing code to schematics, including SKiDL, forces the designer to give up the actual layout of the schematic itself. As a electronics designer in my day job, a well organized schematic is very important to understand the overall design. It does not only show connections, but is also a map of the system. A poorly drawn map complicates system understanding and troubleshooting.

I'm not sure how an object oriented approach would make things easier for schematic generation. The objects (components) themselves do not undergo much data interactions/manipulations. Maybe if you have some examples, this would be helpful for me to understand. As much as possible I am leaning towards a more functional approach, where inputs, data transformations and outputs are more defined.

With a new language, I could decide features that I wanted and more importantly, include more circuit specific features (branch/join/parallel statements). Of course, a python library would be able to produce the same data representation that circuitscript ultimately generates, but one aim of circuitscript is to make it much easier to do so.

The standard lib provides led, supply, res and cap as component functions (basically normal functions that return a component). For LED and supply, they take strings as parameters, this defines the led color and the name of the supply net respectively. Res and cap take a number parameter like 1k, 1u, 100n, etc. Such number expressions are very common in schematics and CAD packages, so this is a important feature to support (python equivalent of using 1e3, 1e-6, etc.).

I have been building a coding agent for small and even tiny LLMs, local inference. I experiment with Qwen 3.5 0.8B but that is too tiny. 4B is a better one for most of my needs. I mix with 9B and then up to 20B models (not on my computer).

It builds on an opinionated tech stack - Rust (Actix Web, Diesel, SQLite) and Typescript (Solid, DaisyUI). There are multiple agents which play roles like PO, PM, Architect, Rust Engineer, Typescript Engineer and so on.

The idea is to go from user prompts to Epics/Tasks - PO/PM do this. Then to go from Tasks to YAML or similar syntax (I have not figured this out yet) and break into Rust and Typescript code dependencies.

I am focusing on the Rust side: how can small models write Model, Controller, Router, User/Permission and custom business logic in helper functions (called from Controller or BackgroundTask). Building a set of types to express business logic, for example in https://github.com/brainless/nocodo/blob/feature/praxis_agen...

Then I will use tree-sitter to build a graph of which business logic (in the helper functions) correspond with which provenance (source of truth given by user).

There is no tool calling for most of the agents, no MCP, no multi-turn chats. Most of the code writing agents one-shot the response with a lot of code reference in their prompts.

This is needed for bare metal coding (in any language) without using the massive monolithic systems from the manufacturers.

You give it your chronotype and your actual itinerary (multi-leg and layovers included) and an optimization engine generates a personalized schedule for light, sleep timing, caffeine and melatonin to shift your circadian clock toward the destination time zone.

At core it turned out to be a complex optimization problem and a real challenge to tackle. I also put a lot of care in the UI/UX, while I usually focus more on backend work. It's working well, I am just finalizing the handling of some of the nastier edge cases

Previously I've shared optio - my project for orchestrating coding agents. It ties into ticketing systems and when assigned a ticket, it launches a coding agent in k8s and works until the PR is ready, resuming for failed CI or PR feedback (https://news.ycombinator.com/item?id=47520220).

Recently I've been trying to expand it from just coding focused to any kind of agent workflow. So now there are cron and webhook triggers, and more general agent tasks that aren't necessarily coding focused (https://github.com/jonwiggins/optio/blob/main/docs/persisten...).

I think next I want to try and add features for long term memory for agents, but haven't decided on a good way to do it.

You could have a dedicated lightweight-agent running a cheap model in parallel to any workload, analysing the workload (like the prompt) and creating "memories" in a vector DB. These could be according to some guidelines. Alternatively, if there's safety risk - storing and approving could be decoupled and split into 2.

If you want to jailbreak yourself I recommend starting with opus 4.7 since it has exceptional system prompt following to a degree where if you put it in a simulated environment and coached it to do as much harm as possible it will happily do so including the fact that it will jailbreak itself and incl. other models to accomplish a goal.

I created a free golf app with advanced visualization none of the paid apps have.

New in the latest release: you can print your personalized Playbook at home (print, cut, fold, staple).

I've been playing on a national amateur golf tour for over ten years. Before each event, I'd spend hours on Google Earth — figuring out where to aim on every hole and which club to hit. It got very cumbersome very soon. I wanted a tool that did the spatial reasoning for me. Take my dispersion, the wind, the elevation, the hazards — and just show me the right line on a flyover. Visually, not in numbers.

So I built Golf Playbook (iOS).

Free, no subscription. Built our course data from OpenStreetMap instead of licensing an expensive commercial database. Different cost structure, different price.

Contributor for an open source scraper -- https://alltheplaces.xyz/ -- which currently has about 4700 scrapers extracting 40-someting million points of interest.

The project aims to scrape location data and other general information about shops (main use case), postal addresses, restaurants, schools, weather stations, marine buoys, traffic cameras, street trees, whatever someone may decide is worthwhile to add to OpenStreetMap, or use as location data in other projects.

There's a decent community of contributors keeping the scrapers maintained and further expanding the number of points of interest which are extracted.

The opportunity I'd like to work more on (time permitting) is the data scraped by this project I feel is heavily underutilised in other open source/community projects. For example, there's a great opportunity to generate a location map once a week of current locations of international restaurant chains, and upload to Wikimedia Commons where every language Wikipedia would gain a high quality infographic of current locations of a chain's restaurants, etc. As an additional example, time-series data from ATP could be used to update a graph hosted on Wikimedia Commons each week where the graph plots the rise and fall of retail or restaurant chains.

I've also recently setup Hermes to be a bit of a project manager for my side projects and it's worked quite well. Gave it a little CLI to see my todos, projects, and "areas" (ongoing long term things). Then it bugs me once in a while when a project is going stale. One of the nicest things is being able to add stuff to the past so if I did work on something but it wasn't associated with a todo I just let it know and then it'll backdate that.

The main project right now is a domain security assessment tool that combines DNS, WHOIS, MX, SPF, DKIM, DMARC, DNSSEC, TLS/SSL, security headers, redirects, and other public metadata into a single report with findings and recommendations.

I've also been building out the smaller supporting tools around it as they come up in day-to-day IT work.

Still a work in progress, but I've been having fun building it.

Squire - A new app for building tabletop armies for popular games

https://www.squire.games

I've been an on off off tabletop wargamer for ~ 9 years and have never been really happy with the options for list building, game tracking etc. Everything was very clunky, slow and disjointed. I came up with a product idea and brand logo but never had time to even touch it until recently.

It's still very early days, but I'm starting to test drive it out and loving it so far. Lots more to do, but would love feedback from anyone that wants to give it a whirl!

Evan-Purkhiser3• 1 month ago

Been learning electronic PCB design the last few weeks while retrofitting some IKEA window shades for Zigbee enabled motorization.

I've really enjoyed the journey of 3D printing and being able to create all kinds of mechanically useful things over the last few years, but I had always wanted to go even further and incorporate some non-trivial custom electronics.

For this project I had a space constraint for the motor controller board, so while I could have probably hacked together a working perfboard, it just wasn't going to be satisfying. So I finally took the plunge and spent 40 or so hours in KiCad learning how read IC reference documents, picking components, and of course, doing the PCB trace layout.

It's really just a 12v→5v buck circuit, all the plumbing and ancillary components for connecting a ESP32 module to a couple motor driver ICs, and some headers, but it is completely mine!

Just got 5 of my boards in the mail from JLCPCB the other day (insane turnaround, less than a week) and was very happy to find that the entire circuit worked perfectly! I did spend a fair amount of time going over the design with Claude though, so I think that paid off (the kicad files are plaintext, so it made easy work of understanding what I was doing).

Still putting together the repo here, but I'm hoping to make a little blog post out of the project too :) https://github.com/evanpurkhiser/HOPPVALS-MRF-01

This is how it starts my friend. Before you know it you have a lot of projects 90% done and living in production without ever getting the last 10% before you think of something new! Currently I'm refactoring a lot of homebrew ESPhome devices to use the ESP32-H2 as it supports Thread. This allows me to remove weak IoT SSIDs while expanding my Thread network node count for better mesh.

Evan-Purkhiser3• 1 month ago

Ah I picked the C6 for it's Zigbee support, I've completely avoided WiFi IoT devices where I can in my apartment. I haven't explored thread at all yet though. Thread / Matter seems like it's going to be more open than zigbee, and potentially easier to develop for?

skew-aberration4• 1 month ago

Looks much better than a typical beginner, congrats. As someone with a bit of experience (and a degree) I'd just suggest that you avoid breaking up the ground plane so much. It's the single most important rule for PCB design. Traces on that side should only be short links to jump around a trace on the top side, where possible. It matters the most for SMPS, RF, etc.

Evan-Purkhiser3• 1 month ago

Appreciate the feedback! I was having a hard time finding anyone with design experience in my social circle, so I mostly relied on asking Claude if something was or wasn't conventional. I did try to keep my ground pour free of bottle-necks.

I put together the guide, made a few iterations and published it and now I am getting more questions than ever and it's turned into a blog too.

I'm having fun but it definitely feels like a topic that is underserved.

More specifically I'm currently working on the 3rd party development tools so in the future anyone can make their game dev dreams a reality and make a simple and fun multiplayer party game for the Gaming Couch platform, ideally in only one weekend! If you're a game dev or aspiring to be one and want to develop and ship your own party game, check out https://gamingcouch.com/developers

The TL;DR of Gaming Couch:

- Currently in free Early Access with 19 competitive mini-games.

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

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

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

Recently added support for scripts (like Claude code workflows) and been iterating on the UI for that a bunch.

I also ended up wanting other customized tooling - a more streamlined way to grep, find files and review code that my agent has written. So I wrote a few plugins for that : needle (finder with UI and sorting functions that suit me better), shuck (interactive grepper that has a workflow around refining grep commands) and glean (a review tool that lets you mark parts of the code as seen, leave comments, view diffs commit by commit or collapsed, etc). https://github.com/dlants/dotfiles/tree/main/nvim/lua

I'm working on Topicle (https://topicle.com), a Reddit-inspired link sharing, voting and discussion platform that rethinks a bunch of basic aspects like moderation, anti-abuse and privacy to try to address some of the biggest pain points. Every moderation action has an admin appeal available, bots and astroturfing are aggressively monitored and policed, comment histories are always visible, no VPNs or datacenter IPs for write operations. Everything is self-hosted (Umami analytics) and there's no data leakage to big ad networks. The full feature set is listed here: https://topicle.com/about

There are also technologies new-ish to this kind of site included like every thread is a live thread via websockets, your post and comment scores update in realtime, notifications are realtime, you can DM other users and receive your messages immediately. So it's distinct from the everything is a hard page load world of 10 years ago and blurring into native software in a browser.

What I'm working on right now is a SwiftUI iOS app, because one of the most interesting observations from analytics has been that the internet is 70-80% mobile devices now, contrary to my 10 years out-of-date conception that people were mostly using the internet on desktops. So a mobile app seems non-negotiable to reach most users. I have a PWA already, but early users have repeatedly requested an official App/Play Store presence.

The stack is somewhat unique in that it's built with a Swift/Vapor framework (https://vapor.codes/) backend, with a more standard React Router 7 (SSR) frontend. I picked this framework mostly because I'm historically an iOS dev, but have found it to be very capable in its own right. I later discovered Apple themselves are using Vapor for some web services and have a team devoted to maintaining the server library (SwiftNIO https://github.com/apple/swift-nio) the framework is based on.

Anyway, it's very early still with launch via Reddit itself only 3 months ago. One of the biggest issues is getting it in front of people without appearing spammy and cold-start on a social platform is also brutal, you need users to get users, and round and round it goes. I may do a Show HN in the future if there's any interest in a real experience using Vapor as a production backend.

Astroturfing is the biggest problem for online forums now. Bots can hide behind residential IPs and AI can generate tonnes of innocuous slop to overwhelm all other content. No human moderation will be able to keep up with it. Anyone building an online forum should think hard about this, I don't think it'll be easy to solve.

deminature2• 1 month ago

I've seen videos of LLM-based automated post generators running on Reddit and it's pretty horrifying. I've also witnessed large subreddits being entirely controlled by bad actors and users having no recourse. I'm definitely not leaving it solely up to human moderation, there are tons of automated detection mechanisms augmenting the human moderation and the system is being built upon every day. I know it won't be easy to solve, I'm keen that somebody should try to tackle this issue, because it's arguably the single biggest scourge of the internet right now and has serious real-world implications, like influencing the outcome of elections. The internet is real-life now, it should be tackled. The landscape is an arms race and there is too much benefit to be had by malign forces to stop trying to shape conversations with bot swarms.

As for residential IPs, I take your point that this complicates things even more. It is very difficult to know accurately which of those are being used as proxies. However, the site has a swiss-cheese model of defence, so if a user passes through one layer, they still come up against all the other layers, so losing one layer is undesirable but still manageable. Again, I cannot claim it to be perfect, but it's working decently so far.

Yesterday I tried to take another crack at reverse engineering my e-scooter. I am don't have the energy to sit down and read through the decompiled android app, so I thought I'd try using Qwen3 Coder next for that but it kept looping when analyzing it, probably due to my terrible prompt. I tried with Mistral Vibe and then OpenCode. OpenCode showed me that the agent was trying to search for all kinds of strings over and over again. I am thinking I'll try yet again this week

I am close to buying a Claude sub but the thought of it going haywire and costing me extra money in tokens is too scary yet. Not to mention how much provider LLMs (not sure on the correct terminology for them as opposed to local) could hamper your reverse engineering efforts (looking at you Fable).

I really want to solve this scooter and have my own app for it. There's a firmware update feature in the app, maybe I could dump the firmware at least and that would help. Anyone have suggestions on what language model would be the best for this task (analyze decompiled and obfuscated android app / analyze dumped firmware ) ? i have a 96gb macbook and would prefer a local one (I guess to make myself feel better for having spent money on it?) but something through OpenRouter or whatever would do just fine as well

Since they're convex polyhedra, almost any shape is possible (in principle, if not in practice) by combining several cells.

What I find particularily interesting is that a solid 3D world can emerge from just a collection of points arranged in different patterns.

Arcane Scholar: a local first application for all your TTRPG needs. Create and manage characters, classes, spells, and more. Then package them up to share with your table.

In the style of Sauron I’m channeling all my frustration and hatred of slow loading tools that require you to pay a subscription, buy the digital book on every platform you want to use it on, and won’t let you use the physical book from your shelf.

For my first pass I decided on focusing on a character creator for a single game and streamlining the process.

I started with the 5.5e SRD but got frustrated with the sheer amount of text without much actual content ( 100+ A4 double column pages of spells, only 1 subclass per class ). Plus a number of weird and frustrating rules that make it hard to create software for. As I’m using Nimble RPG at the table a bit recently and it has a much nicer license I’ve switched to that and been getting on a lot better. Character creation is almost done and I’be moved to character sheets and persistent object storage now. This is the first major project I’ve done with sveltekit and I’m really enjoying it.

Still working on my Dungeons and Dragons combat tracker. It has gained a few users by now (I "launched" it last month) and I am adding features here and there. I think now the next major hurdle is marketing which I am not really good at. I post to reddit and other forums and can get some eyes on the project like that but it is slow going. I think next would be a few youtube videos/shorts explaining the features. - https://topoftheround.com

I continue working on my search engine for Dungeons and Dragons, basically making a specialized chatgpt for D&D + a discord bot that autorecords sessions and sends you the transcript & AI summary when it's done. At the moment I'm trying to figure out how to make it completely free without sinking too much of my own money into it. I'm thinking maybe running it on one GLM subscription or something like that, and it simply is not available whenever it runs out of tokens?

Working on Artifacta (https://docs.artifacta.io/introduction)- durable artifact storage for the files AI agents produce across sessions.

The problem I kept hitting with agent workflows (especially cloud hosted agents) was that the artifacts they produced became really awkward to handle across different cloud sessions.

So I built Artifacta as the boring storage layer underneath. Agents store and retrieve artifacts via CLI, REST API, Python SDK, or an MCP server. Artifacts are grouped by session/agent metadata, deduped on identical content, and safe to retry (idempotency keys), making it easy to handle artifacts across different sessions.

Would love any feedback for those who run mutli-agent orchestration or if you deal with artifacts across different agents.

A simple way to prove that a piece of text, a post, a message, was written by me.

Yes, the burden should not lie on the author, and you could argue it's not even relevant. Still, the default has shifted and there's a refreshing feeling when you're forced to choose your own words.

This is not perfect. You can still find ways to have a machine write a text into this box. But what's guaranteed is the time: writing a message takes the time a human would actually need.

At the very least writtenhuman.com is a statement that the problem it's tackling is real. One with the potential to become a global crisis.

It's an interesting idea, kudos.

Sadly, this will always be a game of cat and mouse. I wonder if it was ever avoidable for the internet to become a hundred of such games at once, between advertisers and ad blockers, trackers and browsers, hackers and developers, search engines and SEO experts...

If your concept took off, someone will make a program that inputs the LLMs text like a human would. It might still take some time (if it isn't possible to hack the timing records client-side), you'd probably have to get busy detecting multiple connections from the same IP, and then they'd work around it...

I’m working on Descartes[^0]. First to help diagnose what’s wrong with a machine.

I’ve started implementing actual background monitoring of the system, and next will be letting an agent build its own layers of tailor-made deterministic rules and statistical models, to "learn" what the system’s normal behaviour is and only "wake up" the agent when something unusual is going on. Either to update its rules and models, or alert the user.

Like the ship’s AI at the beginning of Absolution Gap. Next will be enabling it to serve as the interface for the system. An ops "point of contact" for both the user and their agents for the machine / fleet of machines it’s in charge of.

———

I’m also working on third thoughts[^1], a tool that analyses local agents logs to find patterns and behaviours, identify what works, what doesn’t, how they evolve over time, using deterministic and statistical methodologies and techniques from multiple domains (including, to my surprise, genetics and psychology / sociology), with an agent layer that interprets the results.

I’d like to add a "federative" layer where people can contribute the results, patterns, and findings, without leaking their logs or personal / private data, so that we can all better learn how to identify failure modes, predict them, and see what works and what doesn’t.

———

I’m also having Claude & Codex revive Jasonette[^2], which died off and was turned into some weird paid unrelated thing by those who picked it up. I’d been meaning to but never took the time. But now with agents…

All rebuilt in Swift / SwiftUI on the iOS side, and Kotlin on the Android side. Some features are still missing, but it works quite well! [^3].

Oh, and Boucle[^4] is doing its thing on its own. No idea how it got to 100 GitHub star. My "autonomous dog-fooding expensive pet" is apparently more "internet successful" than I’ve ever been.

An offline-first app to make life a little easier for someone I love and her caregiver. She's been diagnosed with stage 3 pancreatic cancer and food has been a bit of a nightmare for her. Her partner is also not very skilled with cooking, so helping them make this easier is my gift to them. Not a medical device, just a food logging and logistics tool. The privacy aspect of this is very important, so

I am so careful not to let anything not heavily encrypted touch a network request. Sync is opt-in, offline is default. This is very challenging for me, but I want to help her the best way I know: building software for humans.

MCPForge• 1 month ago

I'm building MCPForge.

The original idea came from repeatedly seeing the same workflow whenever someone wanted to expose an existing API to Claude, Cursor, or another agent:

* Parse an OpenAPI spec * Generate tools * Handle auth * Deploy an MCP server * Maintain it forever

I initially thought tool generation was the hard part.

After talking with developers, it seems the bigger challenges are authentication, permissions, endpoint selection, and safely exposing production APIs to AI agents.

MCPForge takes an OpenAPI spec or Postman collection and creates a hosted MCP endpoint. Recently, I've been spending more time on auth injection, tool permissions, and preventing destructive endpoints from being exposed by default than on generation itself.

Still very early (launched this week), and I'm mostly looking for feedback from people using MCP in production.

WebCLI - screenshots are a dead end. MCP is too verbose and clunky. Agents native language is text. Web CLI is just a Unix-y CLI that pipes/translates the web to text. Run any task on a web browser, but don't do it yourself (only the parts you have to - MFA, Login, CAPTCHA, whatever). An agent + WebCLI does anything you throw at it.

  web go news.ycombinator.com
  cat reply.txt | web say -
  web find add comment
  web do 44

just. like. that. Super simple. CLI or REPL. You can do it by hand but you probably don't want to, just give it to an agent. Run web teach to imprint the SKILL.md files into the current directory tree and an agent can hit the ground running. It's the end of browser automation for everything but super scripted fixed path CI/testing etc (those latter things where pptr/playwright/et al are still ok). WebCLI is browser improvization. Try it - 5 days free. I sprinted on this the last few weeks. It's really good. So useful. https://webcli.sh/

About a year ago, I started working on disassembling the NES game Faxanadu. The goal was to fully understand and document the game, and to produce the most thorough understanding of the game yet. It's been fascinating. The game has a two binary scripting languages (one for interactions with items and NPCs, one for NPC/enemy behaviors) and a very interesting graphics rendering layer. At this point pretty much the entire game is well-understood.

Based on this work, there's now a new suite of tools for producing games under the Faxanadu engine, new major mods built with all this, and some work on a modified ROM better built for porting and modding.

Disassembly is here: https://chipx86.com/faxanadu/

And I've been blogging about it at https://chipx86.blog/

Building a universal web-based retro game modding tool along with that work called Nostalgia Studio. The idea is that there's a core foundation for representing game state and building editors, a platform-specific layer for representing things like the NES APU and PPU state, and then game-specific implementations that populate state for two layers below.

Those are the hobbies.

I've been building https://rerouter.app/. Similar products such as make.com already exist but I wanted some things to work differently, for example you can use it immediately without creating an account.

Not sure if it's actually useful yet but here's some things you can do now:

- Categorize instant messages incoming from different platforms using your local ollama

- Use regexes to detect keywords

- Act as a bridge between multiple platforms

- Keep traces of deleted messages by relaying them somewhere

- Choose whether the connections go out from your machine or the proxies provided

- Supports authentication methods that may be against TOS (e.g user account as the bot for discord)

It still needs refining, for example it's not obvious yet how to use the app and the examples are outdated

Got a new paying customer just now, a pretty big Swedish company, been working closely with the team to add an improved review flow to match their needs.

Most interesting work this month came from a customer in Japan who wanted something I hadn't built called "Easy Japanese" (やさしい日本語), which is like a simplified version for non-native readers. Turned into supporting fully custom locales. Also been improving how the GH action picks up manual changes to target translations in commits, they now get ingested back for review, making things a bit more flexible.

On the side, https://infrabase.ai (AI infrastructure tools directory) had its best month yet, up ~40% visitors MoM. Interesting finding is still the GEO angle, visitors arriving from Claude/ChatGPT/Perplexity spend 2-6 minutes on the site.

I do a bit of research and turns out this is mostly true, mostly these websites built for english speaking people, meaning you learn romanian - but starting from english.

at the same time I need to dig in into all the rails 8 goodies. also, I've been hearing about this cloudflare thing, and not knowing what's that about. also, heroku is shit now, so Im curious to try some new server, hetzner u say? - wonder what's that like.

kamal is a thing now, ok.

but coding is ... time and energy intensive, what is this vibecoding ppl talking about?

anyhow May 20th I sit down to "vibecode" an app - see what happens. one thing led to another and here we are

https://vorbim.org/

found some romanian words ranked by frequency. found free open db of romanian words on dexonline. found google TTS to transform text to sound. found that cloudflare has storage sooooo much cheaper than aws s3 (only one I used for decade) found that cloudflare has some neat useful features. found that server at hetzner is pretty cheap and with ai easy to setup. found that fable/opus are great at generating content (with some hand holding) found that AI now is stupid good at building / designing websites.

it was impossible for me to build something like this without second monitor and tweaking css for days/weeks. now? I just tell it make it pretty. god damn. inspiring and disheartening at the same time.

So for example instead of waiting to upload then download a Blu Ray movie, or a large game, you can just add it into the virtual mountpoint and your recipient can instantly play it, or install it, and the download happens in the background with random offset jumps, and caches it locally.

Working on:

https://www.novopathmedical.com/ - evidence-based guidance of diet, exercise, and mental health via SMS for end users. Clinician-guided feedback to bots.

https://github.com/rush86999/atom - ai agent workforce. Harder than expected. There are so many issues with sync with 3rd party apps. Need to launch the first one, so this is getting put on the back burner. landing page: https://atomagentos.com/

Working on Authbound. Digital identities are slowly becoming more prominent. With EU mandatory regulations, it will just boost this market. So we're building eIDAS 2.0 / EUDI Wallet Plug & Play SDK integration for businesses that don't want to figure out the compliance and technical mess themselves.

Side effect: KYC gets stupid cheap. Cryptographic credential verification vs. traditional document checks is not even close on cost (≈90% cheaper). Qualified Electronic Signatures and EUDI Wallet Payment systems are also coming in the following years.

I'm making https://pond.li to try and make our personal archives of text and other media we engage with more available to the present. It's an interesting design space at least, partly because it requires taking a stance on what meaningful/cognitive agency preserving human-LLM interaction looks like

Tweaks to my accessible color palette editor that helps you create Tailwind style palettes for web/UI design:

https://www.inclusivecolors.com/

Most tools only let you enter a single color and then attempt to autogenerate or use AI to create the other tints/shades, which often don't do a great job and are really limiting when you're creating branded palettes.

The focus on this tool is to let you tweak every tint/shade while keeping an eye on accessible contrast. The curve based editor shows you how the H/S/L values of your colors vary across a color scale and is meant to make the editing process quick and intuitive enough that you won't want to give up control to autogeneration.

Playing about with a small side project that's spun out of a need to manage our board game nights better.

Started as a spreadsheet, moved to notion database, now a web app. Idea is groups have collective libraries across members, and planning what to play when is a pain.

Tried to make it easy to get going - take photo of your games shelf and we identify the games there, look them up via the BoardGameGeek API and add the to you library, then you can the pool with others.

It's free if you want to give it a go:

I'm rewriting the open-source core [0] of our product [1] to add more flexible reports.

This is the first time I'm building with the help of AI (Claude), but I don't really let it write code. It has been really helpful in discussing ideas (I'm mostly working alone), like a rubber duck that actually talks back. The code it generates however has many subtle and sometimes obvious mistakes in them, so I decided to write the code myself.

The main benefits over the previous version will be:

- Dynamic reports (ClickHouse queries are generated on the fly)

- Better performance

- Much cleaner and less code

- Better and faster data ingestion including new features, like full support for JSON metadata

- And much more

It feels kinda crazy that I've been working on this project for more than 5 years now and it's still exciting :)

PAX ERP. An AI-assisted ERP for small regulated/job shop manufacturers that have outgrown QuickBooks and can't afford (or take the time) to go through a traditional ERP implementation.

PAX is the easiest ERP to pick up. Our core idea is that ERP should not take weeks of formal training and implementation. We have no formal training, no implementation fees, and are a complete ERP+CRM GAAP accounting system. It's intuitive, well-documented, AI-assisted (never steered), and people can pick it up and start using it well with no questions to our team.

My 8 year old son has pretty poor handwriting which is affecting his exams. I bought him handwriting notebooks to practice but I could not really point where / what to improve ("try harder" / "make it neater" didn't help :) )

Out of curiosity, I tried using AI for help by scanning the paper and the feedback for improvement was quite good (definitely better than mine). So I created an Android app for this (no iphone for now): you write on paper, take a picture and get feedback on what to improve

100% of the world's current email apps are made for users to spend time within it.

But the "ai email app" that should've saved time for them, ends up making the user their own assistant.

So I build https://dirac.app , a decision-based, ai-native email app.

This will be the Next Superhuman, and it's launching tomorrow on ProductHunt.

Aside from dipping my foot into games with Godot I've pulled back an old project to solve a me problem. A few years ago I wrote a tool to tell you what weapons in Dark Souls 1 you are missing to get the Knights Honour achievement on steam.

Part of this required that I manually parse a binary save file and extract the information. This was done through lots of trial and error and looking at other java implementations.

What I would have prefered is some sort of descriptor language that lets me generate the parser and interfaces for everything so I just drop the binary stream into a parse function and get my typed object back.

I'm working on creating a TypeSpec Library and Emitter for this so that you can describe everything in Typespec as to where and what is in the file and have it parse.

I have been working on, Dhee an AI Video Orchestrator. The main problem with creating AI Videos is that it takes a lot of different tools and co-ordination. What if we could have a expect curated repository of workflows for creating AI Videos or Comics or Music or anything digital honestly!!!

That is why I created Dhee Desktop / Dhee Core ( Open Source https://github.com/dheeai/dhee-desktop https://github.com/dheeai/dhee-core ) - which allows anyone to author and run their own workflows for creating AI videos. Its local first, fully customizable, private runner for your workflows or any kind of community provided workflows(bundles) too (Comes with a few built in bundles to generate a full multi-scene segment just from story! ).

Its not just a workflow runner, but rather comes with an AI agent to manipulate the generations. AI images and video models often make mistakes ( extra limbs, wrong face etc ), You can ask the Agent to make changes to the prompts, trigger a rerun, Completely change the character and only trigger the exact shots in which he/she appears etc. It knows and tracks the dependencies.

My mission is to make it super easy for anyone and everyone to be able to create AI videos that they want to watch. I am envisioning a future where you make your own movies and watch it on your PC / TV rather than wait for someone else to make a movie that you want.

You can check out how it works on https://dhee.studio

I'm working on steganographic storage and file encryption tool.

tird /tɪrd/ (an acronym for "this is random data") is a steganographic storage and file encryption tool.

With tird [0], you can:

1. Encrypt file contents and comments with keyfiles and passphrases. The encrypted data format (cryptoblob) is a padded uniform random blob (PURB): it looks like random data and has a randomized size. This reduces metadata leakage from file format and length and allows cryptoblobs to be hidden among random data.

2. Create steganographic (hidden, undetectable) storage (tirdFS) inside container files and block devices. Unlike VeraCrypt and Shufflecake, tirdFS containers do not contain headers; the user specifies the data locations inside the container and is responsible for keeping those locations separate. Any random-looking region of a file or block device may be used as a container.

3. Prevent fast access to decrypted data using time-lock encryption.

4. Use additional tools:

  - Create files filled with random data to use as containers or keyfiles. 
  - Overwrite the contents of block devices and regular files with random data to prepare containers or destroy residual data.
