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

frostbyrne3• 2 months ago

Greetings!

I've been working on something in the vein of a indie game for a little over a year now. It has been a passion project, but I'm starting to come around on showing it to people.

I am a big fan of Telltale style narrative games. I think Baldur's Gate 3 was the biggest revelation of this for me. Taking that branching dialogue and freedom of choice, and tacking it on to a fun combat system was just everything.

When text based GTRPGs started popping up, I found it hard to connect with them stylistically. I found that I needed the multimodal stimulus of visuals and audio. This led me to start building something, and it ended up being somewhat of a cross between a Telltale game, a Visual novel, and a TTRPG.

Orpheus (https://orpheus.gg) is a fully on-the-fly generated tabletop simulator, with graphics, audio (TTS), and the freedom you can usually only find at a real TTRPG table. That means you can play a sci-fi, fantasy, or even a modern setting in your campaign. The assets are made for you as needed. It runs in your browser so nothing to install or tinker with.

Getting the harness right so the AI GM can stay coherent and organized has been the biggest challenge. It took a lot of iterations to get it to a point where it could understand the scenes it was building as the player changed them.

I've built it to be played with either a keyboard or a gamepad so you can play from your couch. You can switch between them as you feel like it. There is a 3D tabletop for combat, full character sheets, dice rolling, lore tracking. I want it to be dense.

Mostly, I’m looking for people who want to try it, break it, and tell me what feels magical, confusing, boring, or broken. My biggest roadblock currently is that asset generation is relatively expensive. I'm currently mulling over whether a playtest would allow for a BYOK setup so people could try playing as much as they'd like, or if I should add turn limits.

You can join the playtest waitlist at https://orpheus.gg/ -- and I just setup a discord (https://discord.gg/pychWyzf) that I will use for early playtests. (Just me right now! Come hang out!)

blinkbat2• 2 months ago

Why not generate some asset libraries to help with some of the rote generation? You could theoretically serve the same asset for a pack of rats to multiple campaigns.

frostbyrne3• 2 months ago

Yes! I am doing a lot of this where it won't break the illusion. Not everyone needs a unique innkeeper generated in every town, but I want to avoid that "Officer Jenny" effect like in Pokemon where she looks the same in every town they visit.

I have a private vs public flag for assets that I'm considering more unique or sensitive, at the AI GM's discretion. I'm using embeddings from there to try and parse if an asset already exists in the public pool or not, and reuse it if possible. The thinking is that eventually I will have pretty decent asset coverage on most standard campaigns. I can't account for people going way off book though.

I have an asset pipeline that tries to determine player intent and pre-generate assets before they're needed. That way we can attempt to hide the "load screens" like retro games did with elevators. I have a kind of sliding scale for player coherency, and if the player has too many "misses" on the pre-generation pipeline it will increase its requirements for when it starts generating.

I may have wildly over-engineered this but I love it. =)

Super cool project and I love to encourage this as I personally think llms in games have not been utilized to their potential quite yet.

vunderba3• 2 months ago

I've been the DM of a weekly campaign with the same group of friends for nearly a decade now. Over the past few years, I’ve seen a lot of attempts at AI meets D&D, and most of them suffer from fairly pedestrian puzzles and stories, and don’t really compare to what a decent, semi-competent human writer can come up with.

I'd love to see a more modern day attempt at something like Bioware's Neverwinter Nights - which was designed so that someone could create a campaign, and then the game would provide the behavior, pathfinding, assets, and everything else with a virtual (or human) DM behind the scenes. You could still tell a human-driven story, but the engine would do a lot of the heavy lifting.

frostbyrne3• 2 months ago

I agree, there is no way to perfectly capture a real table with your friends. This is more an alternative for when life gets in the way of meeting every week.

I think a lot of those attempts you mentioned try and brute force the problem or trust the AI too much on what to generate.

A lot of the same problems that AI coding agents run into also apply to this problem. You have to really manage context (avoid sending a novel at the model) and enforce strict rules in the "engine". The hard part is world building that is consistent without railroading the player and forcing specific paths. I have an agent (for lack of a better term) that manages arcs across each tier. World arcs (nations, factions), player character arcs, NPC arcs, individual scene arcs, and location arcs (towns, cities, dungeons, etc). By prompting all of these as tight, individual arcs with flavor and context peppered in as needed, you end up with stuff that is more compelling. It has to be loose enough that you don't railroad the player. When you decline that NPC's quest, down the road that might have changed the overall arc for a town in a meaningful way.

I won't pretend that I've perfected anything but I have definitely noticed a spark in its writing and world building that I personally have really enjoyed.

I am working on a task manager that’s way more informative and resource efficient than the windows task manager and works on Linux. It also provides an informative dashboard for docker containers and web servers with proxy support and preference for streaming sockets supporting http and web sockets over the same ports.

Puchaczov• 2 months ago

interesting idea!

thisdougb• 2 months ago

After quite a few years of coming up with and implementing 'great ideas' but not being able to follow through to making them revenue generating products, I'm on my best bet so far.

I always wanted to build a real-life puzzle game, which is app/mobile assisted. Had yet another eureka moment, and built a usable prototype (backend plus iOS app). Good feedback from a small circle.

For a while I was aware of someone (I knew by sight) who worked in the same sort of subject matter (but a non-tech). I approached her, we had a coffee, I pitched the idea and how she could bring it to life, as I made the tech side. She jumped on board.

We're two and a half weeks in, have gone full speed and are making something great (for our audience). My future co-founder is amazing, great insights, opinions, drive. We're potentially launching in a couple of weeks, a free/MVP version of a puzzle game.

I've been through many iterations of trying to get something off the ground. Tried tech co-founders, and the last years of going solo (very hard after you've done the coding). But this now feels right. A puzzle app/game for every day people to have some fun. And a future co-founder whose life is outside tech, who's bring a sort of fun energy outwith let's make loads of money or isn't the framework/AI cool.

Balance is good. Contact with reality is good too :)

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

Since last month we’ve stabilized the search UI/UX and have 5 search providers you can choose from and sort as you prefer.

We entered May with over 50 paying customers and have recently launched Uruky Site Search [2] (for website owners, this effectively is our own search index and crawler, which we’ll be bringing into Uruky soon as another search provider option)!

Customers really enjoy the simple UI (search doesn’t require JavaScript) and search personalization (from choosing the providers to the domain boosting and exclusion). We also have hashbangs (like "!g", "!d", or “!e”) when something doesn’t quite give you what you’d expect, though.

You can see the main differences between Kagi, DuckDuckGo, Ecosia, etc. and Uruky in the footer (right side), but one huge difference is that with Uruky, after being a paying customer for 12 months, you get a copy of the source code!

Our main challenge right now is outreach because we want to do it ethically, and it’s hard to find communities or places to sponsor which are privacy-focused and don’t require €5k+ deals. Ideas are welcome! We’ve been sponsoring a project per month (Qubes OS, The Tor Project, and Hister so far), with our limited budget of ~$100 / month.

Because of bots and abuse there isn’t a free trial easily available, but if you’re a human and you’d like to try it for a week for free, reach out with your account number and we’ll set that up!

Thanks.

calculated• 2 months ago

Hey, I'm from the EU and love to see such a project!

One thing I can recommend right off the bat is Reddit - there's many privacy focused subreddits, and also you can share the whole project in EU related subreddits and e.g. r/SideProject.

Would love to try it for a week, this is my account number - 9772263817629091

Keep up the great work!

BrunoBernardino7• 2 months ago

Thanks for the suggestion! We're trying to avoid anything that's social media (though Reddit is debatable), at least for now.

I've topped up that account number for a week, enjoy (I'd recommend removing it from the post because anyone will be able to use it)!

BrunoBernardino7• 2 months ago

So, we actually just shipped the option to include Uruky Site Search (our own index) in the search results, alongside the search providers! Up next is beta image search, which is highly requested.

jfil2• 2 months ago

For site-search, I recommend making it a much better value for money. Sites with 300 pages don't really require a search engine. Imagine people with 30,000-300,000 pages where 99% don't ever change (so don't need a re-crawl) and who get 10,000 total visitors a month. That's a wholly different point on the searches x crawl frequency x number of docs matrix that you can still serve profitably.

BrunoBernardino7• 2 months ago

Thanks for the input! We're going at it by cost, which is heavier on crawling and storage than the search itself (though that also costs money, just much less). Crawling and allowing 30k pages indexed for 6 months for €30 sounds like a loss at a glance, but we're open to experimenting with that for someone who needs more pages and the same amount of searches. Just reach out!

BrunoBernardino7• 2 months ago

We've just increased it to 1000 pages, now. We'll see how that goes!

Currently we’re using AWS and Backblaze B2, but I’m formulating a plan to move to colocated servers. Not being billed per GB will open up a lot of new opportunities. Even at today’s server prices the math still adds up.

aleda1453• 2 months ago

Is it egress or storage that's the main cost driver?

dabinat2• 2 months ago

Mostly storage. Customers upload large files and expect the original file to always be available.

I'm learning about inference by running vLLM on a k8s cluster (EKS), building a gateway to keep a <2s TTFT SLO.

Most recent ha-ha moment: I kept wondering if it was normal that my cluster was only able to process 4 requests per second per vLLM engine (just seemed really low to me).

I realized a better metric is in-flight requests... Each engine is processing 70 requests at any given time, streaming tokens for over 30s.

Code: https://github.com/Nicolas-Richard/vllm-on-eks

iugtmkbdfil8343• 2 months ago

Deeper dives into those uncover interesting limitations that don't seem to be documented anywhere. On the other hand, it is through those reverse shibboleths that I am now able to tell that my boss's boss has no idea what he is talking about llm-wise.

korbonits2• 2 months ago

Have you considered using vLLM on top of Ray Serve (on EKS with KubeRay)? KubeRay makes Ray cluster-aware and there could be some optimizations you could make e.g. keeping that GPU fully utilized all the time :)

nicoinstrument2• 2 months ago

Thanks for the suggestion! Have you found that Ray Serve’s built-in autoscaling plays nicely with custom SLO-based concurrency limits, or do you usually let Ray handle the load balancing entirely?"

Being a weightlifter for 20+ years now, I'm working on a barbell speed and path tracking sensor based on newer IMU hardware technologies, which makes it both more precise and cheaper than camera- or actuator-based systems. Ultimately it helps you lift and train safer and better.

It's an intersection of industrial design, hardware, firmware, and software (and some sport science, of course). This intersection is not yet dominated by LLMs so it's a breath of fresh air.

In an early prototype stage as in "strap a Raspberry Pi to a bar", but it looks promising and I'm happy to move forward, also using connections from my previous 12+ years in China.

frankdenbow3• 2 months ago

this sounds awesome. have any videos of it?

mstaoru6• 2 months ago

Thanks! Working on it, for now it's literally a taped breadboard. :D

era86• 2 months ago

Wannabe powerlifter here of about 20 years as well. This sounds like an awesome project! Is bar-path the main metric for safety and "better" lifting? A project I had in mind, once upon a time, was an automatic "Form Check Friday" for myself using a Pi + Webcam.

notesinthefield2• 2 months ago

Not OP but velocity is typically what these devices are used for. Its a great measure of between-set intensity.

mstaoru6• 2 months ago

Thanks! I think for "canonical" lifts (squat, deadlift, row, to some extent military press) the vertical bar path is mathematically optimal, and for all kinds of lateral or sagittal movements you do more work with weak stabilizing muscles and load joints laterally too. Is it productive work that strengthens your core? Possibly, but it's hard to quantify. It it something that can lead to injury? Absolutely yes.

For more complicated lifts like bench press (J-shaped) or snatch (S-shaped), for example, I would rather set a "golden sample" path with a coach and compare to that.

It's unlikely to be the sole metric, especially given the inverse kinematics of different body types (long/short femur, etc), but together with bar speed, over time, it can provide a lot of good feedback.

cleaning2• 2 months ago

As someone who has been very deep down this rabbit hole and hacked together multiple path and velocity trackers over the years (specifically for olympic weightlifting), there is no extra information that tracking bar path will give you that simply looking at the video won't, and often just adds more clutter. You don't need to graph bar path to see that the bar is looping too far forward after hip contact in the snatch.

Velocity on the other hand is a great metric to track and is used as a proxy for RPE. Mike Tuchscherer was the first one to systematize it for powerlifting a while back, if you've been lifting for 20 years you're probably aware of the name.

a-dub• 2 months ago

i'm curious about how effective path tracking can be in comparison with computer vision based inverse kinematics of the body itself. do all forms of bad form have detectable imu signatures?

i wonder if it would make sense to consider it as a data problem, capture a bunch of high fidelity inverse kinematics data for various forms of bad form/dangerous lifting along with the imu data and then work from there. there could be some interesting and unexpected features that are easier to detect than straying from straight line paths with some tolerance.

mstaoru6• 2 months ago

For me it's a bit of an inverse problem. I go to a public gym (hard to sustain motivation at home) and I absolutely don't want to film myself there.

How about strapping the phone to the bar and opening a Web page with https://developer.mozilla.org/en-US/docs/Web/API/Acceleromet... ?

Seems it would have a much higher reach.

mstaoru6• 2 months ago

Phone accelerometers don't have enough range and sampling frequency to even begin with. Raw, on some rare phones you can sample 800 Hz (enough-ish), but on most 100 Hz max, Web API is capped at 60 Hz, this is all way too low for any quaternion math. They also have much higher noise density which is the silent killer of all kinds of IMU navigation.

I also wouldn't trust a strap to drop a loaded bar from snatch :D https://youtu.be/nrgnH9fTfGo?si=6LLeu3y02iFrwfis&t=65

KronisLV• 2 months ago

A small launcher for Claude Code, to make switching between different providers and configurations easier:

https://ccode.kronis.dev/

For example, if I downgrade from Max to Pro I'd still be able to use the subscription, but also run sessions with other models (less expensive/local) as desired:

  ccode init-config          # initializes a new config file for me to set everything up
  ccode edit-config          # opens it in my editor so I can change, can also include editor as argument e.g. vim
  
  ccode                      # launches whatever my default profile is
  ccode --deepseek           # Using their API key, they have a discount this month
  ccode --openrouter         # Whatever OpenRouter model I have configured in the config file
  ccode --openrouter-preset  # Also supports OpenRouter presets e.g. if I don't want to use quantized models
  ccode --deepseek --control # launches a Remote Control session, shows up in web/desktop app as a regular session
  ccode --deepseek --auto    # overrides the default permissions, --yolo also works
  
  ... (and so on, there's more examples on the website)

Source available, pre-built binaries on itch.io, pay-what-you-want with a minimum price of 0 USD, probably get it for free first if interested in taking a look.

I finally got around to signing app for Mac, which is what this post originally was about: https://news.ycombinator.com/item?id=48075366 (the new versions will be out soon)

Also thinking that I might make it an Anthropic API --> OpenAI API proxy that allows talking to providers that don't support the Anthropic API directly, alongside allowing switching models dynamically during a session (Claude Code wouldn't even have to know about it, it'd just send requests to a local endpoint and the proxy would do the rest).

Early on, but Go is lovely to work with, mdBook is great for getting a site off the ground and I'm really surprised that more people don't use Itch.io for distributing software (or the pay-what-you-want model in general), it's dead simple!

I've been working on Mesaphore, an Excel-like spreadsheet app[0] backed by a Parquet-based file format. The premise is when Excel starts off as the starting point, then over time becomes a data exchange format between systems, and eventually becomes a bottleneck for the system. You still want to provide your users something Excel-like but also want to address the limits of Excel[1].

Majority of code (almost 70%) is generated by Gemini Pro and is extremely ugly. Due to a recent eye injury, I've not been able to code as much as I want, so I'm delegating many things to Gemini. Eventually, as my health improves, I plan to rewrite the entire thing.

A few days back, a book on FreeBSD Driver Development was posted here [0], and everyone assumed a) it's LLM slop and b) a terrible introduction to the topics covered.

I scanned a couple of chapters and realised it likely wasn't LLM generated, it just needed an edit. The intro to C is a hard and weird intro, but then driver development in FreeBSD is hard and weird and people who aren't prepared to get through such intros probably aren't going to get through the rest of it.

Being the contrarian, I've started going through it. I was involved on the periphery of the FreeBSD project ~25 years ago, went to conferences, ran a BSDUG in my hometown, and so on. And I realised I've missed systems programming and FreeBSD itself a little, and in recent years became a little sentimental.

What I've discovered so far in the first few chapters:

1. I miss FreeBSD. And it's weird my muscle memory kicks in and am surprised in a lovely way to find familiar things like /etc/rc.conf work the way I remember them.

2. This is not AI slop. There are issues that I can blame on him not using the same platforms I am (if you're on Apple Silicon, just use UTM and the aarch64 ISO - don't use the VirtualBox config he suggests, as an early example), but as somebody who sees a lot of AI generated content in my day job - this isn't it

3. I have got excited about coding again for the first time in a while.

So, this is my hobby for a while. Go back to where I started, get into low-level systems programming again, I have some ideas on some hardware I want to help out on... it's different to a lot of what I've been working on for the last decade or so, but that excites me.

I have been working for some time on a budget body/facial mocap solution with Unity. Mocap is hard, and what exists is locked behind subscriptions or is just very expensive.

With Unity I'm trying to bundle a bunch of different free, cheap or open source solutions together. For facial, that includes a custom converter from the output of Deadface (based on Mediapipe) with ARKit blendshapes, and also eye movement. For body it's a custom hook to SlimeVR that allows you to mocap with cheap-ish IMU-based DIY trackers, and all that on top of a custom made (not free but open source) physics rig solution that gives you accurate rigid body real time collision, saving on cleanup work.

It's being going really nice despite being an unusual workflow. Hope to release it as a plugin for a in-development sandbox game in the near future. Mocap and animation has been my passion long before i started with tech stuff, and finally I'm able to pursue it.

My own browser game. I created a browser game engine and building my first ever game with it. I can’t wait to launch it, I think it’s pretty cool. I’ve been working on it for 6 years!

The tech surrounding the game is awesome, the game and engine are fully deterministic, discrete (not float based), and bit-packed data structures throughout, powers of 2 everywhere for really fast operations, and logic and rendering are fully decoupled.

I wrote a simulator for the game and can simulate 10,000+ games in around 50 seconds on my MacBook M1 Pro. Purpose of the simulations is Monte Carlo method to tune my enemy AI (not LLM - conventional bots etc)

I've been working on a AI app to replace Claude Desktop and Mobile for personal use.

The main goals are to own my data (memories, artifacts, chats), be able to switch AI providers at any point (if one is down or I want to try a new model), have the same experience between desktop and mobile especially when it comes to working remotely on code.

A bigger vision is to offer everyone a alternative to Claude and ChatGPT they can own just like OpenClaw but with a great app experience.

I hope to have the first beta published by the end of next week.

I'm not just talking GPS coordinates, but speed, direction, motion detection, precise timing between waypoints, being able to play these trips forward and backward, step by step, etc. I'm talking time-travel debugging for GPS applications.

It's early days. I'm not even sure it's possible.

Basically: smelt the malachite with flux and charcoal to get pure copper, flow that into an ingot mold, hammer it into shape. Then I’ll have my own ring, with metal I collected with my own hands

i am working on an offline weights harness for non-technical people, writers mainly. it's designed to work forever but also be adaptable as more weights get released etc.

it enforces very few paradigms, runs in the browser, and allows users to view and edit agent config files within the UI.

it's kind of a nightmare to try to figure out how to do this appropriately, but it's an interesting challenge and i have seen very few (~0?) projects with an approach like this ...

all the offline harnesses are optimized towards coding, vs. general text manipulation aka "writing."

hoping to publish v0.1.0 by the end of may.

My "prompt" was, uh, simple: "Turns out, you don't need water to live."

TY for the error details! Helped me track down what was happening here - turns out nginx had a 60s timeout setup for calls, and promps average around 55-65s to return. Meant it was working 100% on dev, and apparently every attempt I had on prod was under that 60s count.

Just moved things to a websocket connection for the return. Should be working now - here's the image it generated for "Turns out, you don't need water to live": https://diffui.ai/files/brand-shares/2ff1b00a-d698-43ea-a42e...

I’ve only really had trouble integrating Withings.

Working with Apple was also challenging because I had to purchase an Apple Watch or iPhone (the data is stored locally only, with no server or API to call, which is great from a privacy perspective) and then deploy specific code on the device.

I’m not sure if this helps your use case, but I was planning to make the API public and create a CLI (similar to Sentry or Grafana’s gcx) to access it. But if you want a local first option, not the best solution

The core ability I wanted was to support RAW files as inputs, with DNG files as outputs. This is done using either LibRaw, or Adobe DNG Converter (runtime options).

I have been really into macro photography the last couple years, and have been slowly working on trying to build my own program to handle the focus stacking.

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

germinalphrase2• 2 months ago

I’m building a small map application that allows me/friends/family to explore data overlays about morel mushrooms phenology and habitat (ground temp/moisture/terrain/aspect/tree species/etc) in our area. There’s some lightweight forecasting and timing models to help guess at near-term fruiting. I had a big push about a mouth ago to tighten things up, and initial experiences in the field this year have been very promising.

I’ll keep chipping away at it this year, and probably expand beyond morels to other seasonal natural phenomena that my people enjoy like smelt/salmon run, wildflower blooms, etc.

jonnycoder• 2 months ago

I had a similar idea. I picked 10 lbs of morels last year, first time picking. It was a recent burn area from 8 months prior. I was just back out to the same area and there are no morels, but lots of small orange cap looking mushrooms. chatGPT pro said first year is the best and then it drops off on the second year. I might try a much higher elevation spot in a week or two, but it really sucks. Last year I was finding morels on southeast facing slopes. I'm sure north slopes produced later on as I saw people coming off the hill when I drove by.

germinalphrase2• 2 months ago

North-facing (in the US) tends to produce earlier due to the increased warmth with south facing producing mid to late season. Fruiting has been suppressed by me due to lack of rain. Best of luck!

A timelapse platform powered by community photos. The idea is to place a mount and QR code at fixed viewpoints around the neighbourhood. People scan, photograph the view, optionally add their name, and submit. Over time, the platform stitches those shots into a living record of how the place changes with seasons.

Just finished the software side using a boring technology and am about to order the materials for the first few locations. Curious to explore photo alignment once real submissions start coming in. Stitching all slightly different angled photos into a smooth animation seems interesting.

I was responsible for multiple RADIUS services used by millions of people every day. The existing software is slow to build with, difficult to scale and expensive. I couldn't let it go.

Step one was building the platform to run it on and make it sustainable as a business. Step two is implementing protocols like RADIUS that lack a separated compute/storage model but should really have one.

I chose C# because I know it, and build native single-file executables using AoT.

A high-throughput multicast Bitcoin transaction distribution system, with a roadmap towards billions of transactions per second.

Features:

- Control channel for block header announcements, operational mechanisms, and network topology automation

- Separate channels for subtree, subtree grouping, and transaction load

- Transaction load sharding by deterministic multicast group membership based on TXID

- Transaction specialization filtering and retransmission both unicast and multicast, to connect edge networks only interested in a portion of the transaction load for whatever reason

- NACK-based retransmission of missed packets via hash chain gap sequence tracking (per sender, per shard) with automated caching endpoint beacon discovery and tiered network distribution

- BGP-AnyCast based transaction ingress

Basically all the topology pieces to scale the actual small-world network for Bitcoin miners or transaction processors; dense at the core, with layered and sharded group distribution towards users at the edges. Right now just site or org-scope multicast in planned, but provisions are being made to extend via MP-BGP eventually.

For BSV Blockchain but could work for the other Bitcoin variants too, if they ever wanted to scale.

I finally managed to finish a project and publish my first game on Steam: https://store.steampowered.com/app/4195030/balls/

It's a short chain-reaction game in which you explode balls bouncing in the screen, and need to build up to target scores. You build bigger and bigger combos as the game progresses.

It was a blast to work on it, starting with a small toy and just adding features that "felt right" until I had a game that was fun to play. It was quite hard to find a balance though, so a lot of numbers are arbitrary - but I enjoy seeing people breaking the game in new ways and finding new builds.

These days I've been working on patching reported bugs and sharing the game with people. Now after the latest patch, I feel like I'm done, but I feel like going back at it and adding an idle mode. And maybe simplify the codebase so I can test and iterate better, and then add many more ball types...

I know that any good LLM could replicate this pretty quickly, but I made this myself and I'm still feeling proud of the accomplishment :)

I'm continuing to focus on ways to set strong code quality guardrails in an era where most code is not handwritten.

The result is http://getcaliper.dev.

It has a number of mechanisms that help substantially:

1. It can extract deterministic quality checks from your CLAUDE.md text; these checks then get executed after every agent turn.

2. It performs a lightweight ai-powered review at every commit; feedback goes directly to the agent, which can then make corrections.

3. It performs a more 'traditional' deep AI review at merge, or on-demand.

Free to use, just bring your own API key. Any and all feedback is welcome!

The other day I got into some pretty weird territory with Claude, trying to map out what an immortal ASCII cat would look like. Basically an autonomous Tamagotchi.

The idea was to create a quine that runs forever on something like Akash network with its own crypto treasury to support and pay it's bills and try to replicate. It would then talk to an LLM for support and actions on what to do to stay alive.

It got pretty out there. Stored some of the ideas here.

Mainly working on https://localhero.ai, automating i18n translations for product teams. Basically runs as a GitHub Action, translating new strings on PRs matching your brand voice and glossary. Got our first fully selfserve customer a few weeks back (found us through the docs). Interesting work lately has been improving how the system learns from manual edits, when someone tweaks a translation in the UI, it feeds back into translation memory and influences future translations in a smart way. Also did stuff like improving our agent skill, so coding agents get glossary/style guide context automatically and they can write source copy that better matches the brand.

Been pushing some new stuff on https://infrabase.ai as well, my AI infrastructure tools directory. Traffic growing steadily from comparison and alternatives pages. Interesting finding is that blog posts rank better but get fewer clicks now because AI Overviews, interactive comparison pages still earn clicks. ChatGPT has also started citing the site more as a source. Adding new content and polishing existing parts of it, added a page focusing on EU based services at https://infrabase.ai/european.

Been working on https://searchcode.com/ again which I bought back, albeit as code search tool for LLMs. It solves the “should I use this library” by allowing the LLM to inspect search and analyse it before integration. Can use it to compare multiple repositories before downloading. It comes with a large amount of token savings and can be really useful when wanting to learn about a codebase.

Since it does it anyway I added dossier pages to it as well https://searchcode.com/repo/github.com/rust-lang/rust Which is useful for humans, and shows what the system is creating.

Best part is that I get to use the tools I have built, so https://github.com/boyter/scc and https://github.com/boyter/cs to improve it which benefits anyone using those tools.

A desktop client for Repomix. Repomix is a CLI which allows you to summarize all the code in a repo in one txt or md file so you can in turn feed it to an AI model for analysis. It absolutely gets the job done it its current state, but it is a personal project so there may be a few rough edges.

https://github.com/KevanMacGee/Repomix-Desktop

It's open source and has no official connection to Repomix. But the developer, yamadashy on Github, knows about it and seemed to like it enough to add it to the Repomix website under the community projects.

I like being able to paste all the code into a browser window and have lengthy discussions with ChatGPT, Gemini and GLM. Doing so in the browser saves tokens over doing it in Cursor or Codex. I like using the Projects feature in ChatGPT in the browser and Notebooks with Gemini because that gives the model context and history on whatever I am working on. It was one part scratching my own itch, one part learning about Python and Customtinker.

It's made specifically for when you just want to get the code and paste it, no muss or fuss. It doesn't have support for flags (yet?) like the CLI because again it is built for speed. Besides, when I want flags, I like using the CLI instead to get granular. Repomix Desktop is for "just give me the code."

I'm a self taught coder so I'm very open to feedback.

We're working on Drawers (https://drawers.computer), a macOS app to give each of your projects its own dock, space, and windows.

We integrate with macOS spaces to switch out a project-specific dock on each space, containing only the resources you need for that project. We made it possible to add granular resources instead of full apps to the dock (think specific slack channels instead of the whole slack app), to keep the dock hyper focused on what you need.

We built this to stay focused while working on the computer, and we thought that the native interface mixed all our projects together, causing us to get distracted.

Looking for beta testers! Free download from https://drawers.computer

This is really neat. Is there a way to handle the one app, with one window, being used for multiple tasks?

For example, I have Codex running doing two things at once, and I wish I could have two windows in two spaces (two projects.) Slack has multiple channels.

Both these aren't native macOS apps but I wonder if you can use the macOS tabbing support to at least get this for well-coded native apps?

BrandiATMuhkuh• 2 months ago

That's epic. Will try it ASAP.

Was look for exactly that (but for Features). currently I'm using superset.sh which works great. But the problem is that such tools need to re-implement everything (browser, terminal, etc.) while a "VM-like" approach doesn't.

It is possible to "clone" a drawer that auto starts server, browser, etc. So I can start new PRs quickly and jump between them while the agents run in the background?

I love that idea, and had a similar one once (never realized), because I run many projects at once (and more than one role: personal / job_1 / job_2).

What I'd suggest is that you isolate the project spaces from one another so that a e.g. a Web browser crash caused by one project space cannot drag down the rest. BTW, I'd pay for this!

Keep building.

da-x• 2 months ago

Since 2022 I have coded something similar for myself, only for Linux for each of my notes, e.g. each and each every small or big task gets its own bundle of things that are attached to its 'task note'.

Each note gets a wholesome 'virtual desktop' "space":

- A markdown file (in a Git repo for all my notes)

- A working directory for project files

- Virtual desktop in hyprland that opens up as a terminal/browser split

- The terminal spawn a restorable tmux session where I edit the markdown file and open related terminals, where the note's workdir has its own `bin` directory in $PATH.

- Also, an ironbar widget showing the name of the current note at the bottom of the screen.

- Time tracking app to remember how much time I worked on each note.

And they are all bundled up together with save/restore capability, kinda like a VM, but on the application level. The idea is to support multitasking and never lose focus.

All I really deeply want on this front is for the ability to have my IDE and CLI apps specific colors for specific projects. On mac, being able to 3-finger swipe up to mission control and then swipe down on the app I want has been by far my favorite way to navigate windows. The main problem I have is that the color of the app itself is the main way of telling them apart. I wish I could use a particular VS Code or Terminal theme for just one instance

For a long time I wondered how SV startups got such pretty landing pages (here’s a comment I left 2 years back: https://news.ycombinator.com/item?id=37421273). I wanted one for my side projects but couldn’t afford an agency, and the templates online were boring. Creating the page was only half the problem. I also needed somewhere to collect emails for the waitlist.

After AI happened, I built an app (promptfunnels) to scratch my own itch and generate funnels (fancy name for landing pages with a purpose).

Then came the harder part: marketing it. Coming from a tech background, I knew nothing about marketing, so I started reading and came across the $100M Leads book. I realized codifying those principles together with funnels and marketing automation had a real market. My family, friends, and acquaintances became the first customers. A friend joined me as cofounder and we both quit our jobs to do this full time.

As we talked to other startup founders, they kept describing a tangential problem they called GTM. At the core it was the same thing we were solving: marketing for non-marketers. So we pivoted to RevMozi(https://revmozi.com/), which helps non-marketers do both inbound and outbound GTM.

We’re dogfooding the product and coming out of beta next month.

Wish us luck.

I am working on a framework that lets you easily create tools inside the Django Admin - https://djangocontrolroom.com

I've published several panels under this banner already (tools for redis, caches, celery, etc.); I am currently working on a base library layer for tools to inherit from and to make it easier to create new tools.

Essentially, the point of all of this is to make it so that you don't need so many external services; Instead, DCR provides self hosted alternatives. This in turn makes it a lot easier to build and productionalize something using Django.

Reception has been decent so far and I estimate several thousand current adopters (Its hard to estimate based on download numbers alone.) For May I will finalize a common design language, further formalize the plugin system and how it works, and likely release a new panel.

Social Maps: a user reviews and ratings service for points-of-interest (e.g. cafes) in OpenStreetMap.

I’ve been trying to reduce and eliminate my reliance of the Big Tech and the lack of user reviews and ratings was always a big pain point for me each time I tried to switch away from Google Maps.

I’ve started building a service where users can write reviews and rate “places” (POIs) in OpenStreetMap database, such as a cafe, a museum, or a shop. It’s a quite straightforward CRUD app with bunch of OpenStreetMap-specific features such as logging in with OpenStreetMap and querying places by their OpenStreetMap metadata.

It’s still in active development but it has good docs, a great API reference (including an OpenAPI spec), a demo app with the entire planet imported and queryable, and an early stage Android SDK.

The idea was borne out of wanting to use the review tools that you get on existing sites like GitHub, without having to push and start bloating PR lists. You'll be able to leave yourself comments and code suggestions after review, which you can then pull out in a Markdown file to feed back to your coding agent (or anything else for that matter).

I'm also trying to include some optional (very optional) AI extras where you can use your own keys, and then get a tour of what you've changed and a quick overview of the changes.

I’ve been working on an OSS backend-in-a-box called [aepbase](https://aepbase.io/).

For the past few years, a group of us from Google, Microsoft, GM, IBM, Roblox, Rubrik + more have been working on a design standard for APIs called [AEP](https://www.aep.dev). The goal is twofold: learn from our companies mistakes around APIs and enable better tooling with less configuration.

We’re at a point where AEP-compliant APIs get a resource-oriented CLI, MCP server, full UI, and Terraform provider for near-zero configuration.

Aepbase has been my way to tie the whole ecosystem together. You run a single binary and define the schema for a resource with one API call. Now, you’ve got a full set of CRUD APIs and support for CLI/TF/MCP/UI. After one API call.

It’s a really cool way to tie together all of the work AEP has been doing.

Love to hear HN’s opinions on all of this. We’re still trying to figure out the best way to sell people on AEP.

I'm working on turning our statically-typed formula engine -- that we use for Calcapp, our app builder -- into a real hosted solution (as well as a library). I discussed it in July last year (https://news.ycombinator.com/item?id=44702833#44704642) and have been working full-time on the project since the beginning of the year.

I figured "I already have a battle-tested solution, I just need to make it modern and spiffy, build a website for it and see if there's any interest -- in the age of Claude Code, this should be fast work!"

Wrong. Taking an internal library and offering it to others -- complete with documentation and modern tooling -- is an immense project, even with the help of AI agents.

Is there a market for a "formula engine in a box"? I don't know. But I also didn't know whether there would be a market for Calcapp either, and that has supported me working full-time for the past seven years. So I'm willing to take another chance.

In exe.dev you have a subscription and you get some constant compute, paid whether used or not. that compute is shared between the vms. In shellbox every box has its own dedicated compute and if you don't use any, you don't pay.

Shellbox also gives an ipv6, an email endpoint, wakeup on the web endpoint, it supports nested virtualization, docker, etc. And... it is much cheaper even if you use it 24/7. Ahh and also you can send ssh exec commands, ssh forwarding, and more. It is "real" linux, like you get on classical vps providers

Paste Redactor. It redacts Personable Identifiable Information (PII) from your clipboard when you copy and paste text. It uses a custom trained local AI model so that your PII never leaves your device. That is what it does now. Currently working on it to make it work for agents as a privacy protection layer. The idea being that the most powerful AI models live in the cloud but need access to your local files to be useful. We instead want everything to go though a local protection layer before it is sent to the cloud possibly with labels and then reconstructed locally when the cloud sends back its results. Kind of like a Adblocker but for agents and private data instead.

Right this second I'm looking for an alternative to After Effects that runs on Linux systems, as kdenlive has some limitations with its layering implementation. I'll probably give Blender and Godot both a whirl, as I want to get more comfortable with those tools for future projects.

vunderba3• 2 months ago

Nice job. I'm assuming this was inspired by Crypt of the Necrodancer? It even has a similar looking "bounce" motion when the main player moves.

zeta01343• 2 months ago

Aye, the inspiration is not subtle. Technically it is the latest entry in the "rhythm-based roguelike" genre... which to my knowledge mostly includes CotN and its sequel, Cadence of Hyrule. Both are excellent, and I recommend them highly. Of course I'm unaffiliated, so this is more of a spiritual successor (... demake?) and is its own thing in terms of IP.

I can't overstate just how much I love seeing a NES game developed in 2026. It looks great. I really like the music too.

Have you considered also releasing it to itch.io? (I don't do business with Steam due to DRM and their inaccessible website.)

I would happily purchase a NES ROM file so I could play it on my pitendo (RPi3 in a case that looks like an NES).

I'm not well versed in video editing. That said, the people I know who are tend to use Da Vinci Resolve.

zeta01343• 2 months ago

It is indeed also on Itch. I'm planning to release both, along with a physical cartridge at some point. It's a real NES game, so a ROM is included. (No DRM, of course. I'm not even sure how you would achieve DRM on a ROM chip.) I test on an Everdrive N8 Pro. It's a big game, so simpler flashcarts tend to not be able to run it.

Working on Marmot https://github.com/maxpert/marmot recently added support for vector index. My local benchmarks show pretty decent QPS with less than GB of RSS on DBpedia dataset.

Interesting part is that I started off implementing a research paper for indexing and performance was not good enough. I ended up tuning things up for my own use-case and ended up with good enough replicatable RAG store.

http://autonoma.ca/calculators/rocket/antimatter/

Given a distance, an allowable time to reach that distance, a payload to send, and an expected exhaust velocity, how would you calculate the time required to convert energy into antimatter fuel and how much antimatter needed to arrive at the destination (starting from the Moon)?

There are a few side calculations, such as the size of the radiator, estimated footprint of the fusion reactor itself, and how much metamaterial is needed. This is to help figure out timelines for a sci-fi novel, so ballpark answers are completely fine.

The calculations yield what appear to be values around the correct order of magnitude. Would be delighted to have insights, comments, and corrections.

The Ubuntu DDoS got me to thinking: If we had a critical need to respin machines (like our data center caught fire), we would have been in for a real challenge. We run apt-cacher-ng, but it did nothing for us during the DDoS, and worse: Every few weeks or a month ac-ng will go out to lunch and we have to fix it.

So: ac-ng didn't reduce the impact of the DDoS, but it does lead to impact when there is no DDoS. Worst of both worlds.

So I'm working on an apt-cacher that goes to lengths to keep working as much as possible when the upstream is down. It will check the repo metadata and keeps a list of your "hot packages", and will download those before flipping the new metadata to be live, effectively a snapshot. It won't allow you to download a package you've never downloaded before in the case of a DDoS, but packages that you do download regularly (machine re-installs, apt updates), it will ensure are available in the repo.

I'm calling it apt-cacher-ultra. It is pretty early days, it'll probably be another week before it's ready for a beta. I'm running it in my dev cluster right now, successfully.

I'm working on https://engine.build

It's a durable orchestration system for AI code generation which solves the problem of not being able to trust LLMs to complete long running (and high quality) implementations without having to babysit them and monitor the process, which is what I think is the most exhausting part of coding with AI.

You start with a spec or programmatic task list and the engine runs the whole workflow: implementation, verification, review, fixes, and finalization.

It treats agentic coding like a durable CI-style process, with state, retries, reviewer feedback, commits, and auditability built in. It's externally orchestrated, meaning it's not the agent running the loop, it's simply agents being used as tools and spawned in the loop as needed without awareness of the loop itself.

It's going to be open sourced soon and it's not meant to replace your IDE or Agentic Harness of choice. You keep using codex/claude code/open code/cursor/pi whatever you want and simply delegate the actual implementation to the engine, through MCP/CLI and other integration points.

It supports any LLM provider so you can have GPT 5.5 implementing and a mix of Opus 4.7 / Deepseek v4 Pro / GPT 5.5 reviewing at every phase for example.

alasano2• 2 months ago

Thank you!

I've got a lot to say on the topic but I'll be making a video for launch showcasing everything.

For the open source angle, I think it's just a net positive for more people to have access to a way to build with LLMs without being exposed to AI related burnout.

And for open-source projects using it, the engine can act as a quality gate for PRs by requiring contributors to go through a repo defined implementation and review process.

Looking forward to getting it out :)

I'm currently fighting Garmin's wonderful Connect IQ watch app platform (it's horrendous).

I'm working on <https://untether.watch>. Trying to shift 20-30 micro phone interactions to the wrist per day to ultimately reduce phone use. Dumbphones are too extreme - you need a smartphone for certain day-to-day activities (banking etc.)

The watch is a great form factor - it's got a crap screen (MIP), the ergonomics are awkward (rotate and look down), it has limited capabilities. But that's the point! Do essential quick actions and leave the phone out of site.

Requires Android companion app to do the heavy lifting. Use the (head)phone mic and STT to reply to any android notification and make notes. More features to come.

Garmin's SDK is seriously challenging. APIs are often broken across firmwares, limited developer tools and testing is tough.

I'm working on JRECC, a Java remotely executing caching compiler.

It's designed to integrate with Maven projects, to bring in the benefits of tools like Gradle and Bazel, where local and remote builds and tests share the same cache, and builds and tests are distributed over many machines. Cache hits greatly speed up large project builds, while also making it more reliable, since you're not potentially getting flaky test failures in your otherwise identical builds.

I'm working on https://www.certkit.io. It started as a solution to handle TLS certificate automation for my other SaaS products, but we realized other people who run on-prem workloads might get something out of it.

It uses Let's Encrypt by default. We use delegated DNS to handle ACME challenge validation (we run the DNS, you just CNAME to us). This means you don't need to give us DNS credentials or anything. And for HA workloads it's great, because there's a central clearinghouse for certificates - so all the machines in your web farm (or whatever) get the same cert, but you don't run in to rate limits with LE.

We're recovering Windows Server guys so we made sure our automation works for painful windows workloads like IIS, Exchange etc. too.

We've had enough interest that we're building it out for real. Just left beta last month.

I've been vibecoding* a calendar-based personal note-taking thingy: https://github.com/cu/doneski

The idea is that each morning, you click the "New Day" button, and your Todo list along with other notes carry forward from the previous day to the new one. When you accomplish something, you add it to the Done section. Other sections can be added as needed. I have been using a text editor and/or shell script for this purpose for about a decade, but have been inspired to make it into an app now that I can delegate the boring bits of app development. It is not quite done yet, but it's getting close to being usable.

(* To the inevitable downvoters, this is in part an experiment to get familiar with what SOTA LLMs can handle. With the intent of comparing it to local LLMs once I get my Strix Halo set up as a coding assistant. I only code as a hobby currently, and have too many other hobbies, and this app wouldn't exist without something else doing the heavy lifting. That said, this is a pretty low-stakes application and I don't commit any code that I haven't reviewed and don't understand.)

I've been working on RVW, my adaptation of the standard transformer model that is capable of online continual learning without catastrophic forgetting. I finally published the first pre-print of my early experiments: https://doi.org/10.5281/zenodo.20064617

Now I'm working on expanding the work into more parameters and improving performance. I just finished an extremely harsh test of a Nemotron-flavored RVW that consisted of stretches of a random assortment of domains interspersed with long runs of single domains. Across all of it the model didn't forget (and actually improved on some of the more challenging domains). PPL on SmolTalk is still in the ~18 range, which I'd like to get lower, but this is all with only 4B params.

Currently, I'm training a Llama 3.2-flavored RVW with only about 2B params to see how that turns out. Depending on results of that, I may take it to Gemma 4 next.

It's a little web application that allows for the ranking of all kinds of abstract entities. Think of the merging of Goodreads for books, Vivino for wine, Letterboxd for film, etc. This will allow you to instead rank whatever you want across a variety of different categories in a single place.

Using your rankings across all these different fields, you can draw analysis of what you like, and in future I'd like to add a little personal (not an ad) recommendation engine to help you find new stuff based on your actual interests across loads of different categories.

From a technical point of view, its been a great learning opportunity on how to fully host a complete stack using an opiniated, but cross-platform orchestrator, allowing me to host this wherever (bare metal VPS, homebrew system, cloud provider) in a flash.

I just started on an open source and open weight supervised learning model to recognize japanese kanji characters drawn on the screen.

I have a working prototype written in Julia which is a very simple neural network. The input is in vector format so traditional convolutional neural networks don’t work out of the box but I swapped the convolution layer with a path simplification algorithm and it worked extremely well. Like 20 samples per character (from a set of only 5 hiragana during prototype phase) was enough to get 100% accuracy in a test collection of 5 samples per character after only 30 iterations of training.

I plan an working with free and open data, which I don‘t think exists for japanese kanji characters (at least not in vector format; KanjiVG only has one sample per character and I need dozens) so I also build a crowdsourcing web site to collect data from random people on the internet.

I am planning to run some more experiments with my prototype model before I release the crowdsourcing web page to an actual server though.

Builds are faster, I store 7x less data due to better deduplication, I can run security scans faster due to not having to unpack tarball layers, etc, etc. I want to be the default registry for all ML related work, in the future.

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 realtime transit information to billions of people around the world.

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. I wrote up a blog post explaining how to set it up here: https://opentransitsoftwarefoundation.org/2026/04/setting-up...

aaronbrethorst3• 2 months ago

There are several different ways that OBA can be deployed and used for a transit agency or a group of transit agencies in a given region. I'll give you four examples, but this isn't an exhaustive list:

1. The Puget Sound region, where a regional transit authority, Sound Transit, currently maintains their own OBA servers on behalf of a dozen individual transit agencies. Sound Transit piggybacks on our official OBA apps which you can find in the Play and App Stores. The official apps also work in 10 other cities across the US. This is the ideal for us—and transit riders, imho, and similar to what you see with apps like Citymapper or Transit.

2. New York City, where MTA runs their own OBA servers that power their own branded app and realtime signage throughout the five boroughs.

3. UC San Diego, where the university is using OBACloud to power real time transit information systems for students on campus.

4. Republic of Cyprus and Malaysia (yes the entire countries), where enterprising individual developers have set up their own OBA servers to power realtime transit information systems for their fellow citizens.

The underlying OBA server provides a rich set of REST APIs that make it much easier to build a public transit app than using raw GTFS and GTFS-RT data: https://developer.onebusaway.org/api/where/methods

We also have SDKs for many major languages so that agencies and independent developers can build their own apps on top of OBA servers without having to fiddle around with the intricacies of our APIs. https://developer.onebusaway.org/api/sdk

~~~

Integration with Google Maps is important, and a "yes and" solution. I think there's a lot of value in having public transit-focused apps, especially ones that don't have advertising or questionable privacy issues.

I'm working on https://vtxmacro.com, a free and fully autonomous LLM trading platform. Basically have any model you want trade for you. Right now I support ~860 models across 16 providers (including OpenRouter), plus Local AI and OpenAI Compatible endpoints.

The bot settings (system prompt and user prompt, temperature, reasoning, etc.) are 100% transparent and customizable, and all users can view and copy anyone else's settings from the leaderboard. The goal is to build the best trading bots possible by seeing what works.

You can run a bot on Gemini 4 31B with a free tier Google AI Studio account (I'm running 5 bots on it myself). Or just run Gemma 4 26B on your PC if you have the GPU for it. I'm running 5 on my 5090, so I'm trading with 10 bots total.

The platform is connected to Hyperliquid and you can trace all the trades on the blockchain from the user's Analytics page (always public).

The way it works is you set a loop interval (default 1 minute) and the model receives the candles, market stats, indicators, account balance, current positions and so on and decides Buy, Sell, or Hold and how many units.

It's still experimental but I have already processed 1m+ prompts, 10k+ trades, and almost $1m in volume since January 2026. I have around 15 bots running right now, you can check their PnL on the leaderboard (public). I've made a lot of changes in the last few weeks so most recent either 24h or 7d results are the most relevant. The model you use is super important (Gemma 4 31B so far is the best value I found, better than Gemini 3 Flash and you can run it for free) and also the coin you choose is important too. Preferably, you want something that's trending. My friend's bot did well with ZEC and VVV this week.

Right now I'm working on improving reliability (I bought a Japanese VPS to run my own HL node), and this weekend I moved the app from Render to my own DC VPS for 10x+ cheaper and 1000x more bandwidth (25 TB instead of 25 GB, seriously if you're using Render and want cheaper infra look into buying your own VPS).

I'm also implementing CLI/MCP for OpenClaw support. And next is an automatic screener that will use LLMs to pick the most promising cryptos to trade (since I noticed this has a huge effect on PnL).

If you have questions, let me know, the Trade page has my Telegram group link.

kukkeliskuu7• 2 months ago

How well are these performing?

fomoz2• 2 months ago

You can check in detail on the leaderboard, but I suggest you look at the last 24h to 7 days.

We've been playing with different settings and models since January, older wallets have had some bleed with Gemini 3 Flash and bot settings that didn't perform well.

We've been running bots exclusively on Gemma 4 31B and 26B for the last 7-10 days and they've been either breaking even or trading very well, it really depends on the coin. I think around 10-30% gain for the good cases for the week.

It's still experimental, I only put $100 into each bot (and that's what I recommend to my users) so it's not crazy money, but once we're comfortable we'll put more money into it.

We're working on AI user testing, to make it dramatically faster and cheaper for product managers and dev teams to find major usability issues with web sites. Give us a web site and a task users would do (e.g. "Add a pink shirt to the shopping cart"), and we have some AI users try their best to do the task. The output is a report with a prioritized list of problems identified, plus narrated videos that show each AI user trying the site.

If you want to try it out, we offer some free credits at https://fuguux.com

Any feedback you have would be incredibly helpful! We're considering more kinds of reporting, support for QA testing, better integration with CI/CD, and more.

Note: we don't want to replace real user testing, but rather complement it. With AI user testing, you can get quick feedback on potential usability problems in hours for a fraction of the cost, making it so you can iterate much faster. We advocate doing user tests with real people to understand problems that require domain knowledge or nuance.

Acoustic diagnosis of electrical problems on the electric grid!

I'm building a tool that allows you to determine the health of an electric transformer from only your phone. It tells you:

    - the loading
    - the health of the windings and core
    - and whether the phases are unbalanced

I used to be a submariner, so my professional background is in power plants and sonar analysis, so I'm getting to combine the two in this.

Acoustic diagnosis of electric issues is FASCINATING, and it feels like there hasn't been a lot of research into this, so I have been slowly chasing down various acoustic patterns I find and try to derive them from first principles of physics.

I'm making an iPhone app for it, and Xcode has been truly awful: non-deterministic, crashing all the time, and error messages that tell me absolutely nothing. I would like to use xtool, but it doesn't have the preview, which I need for debugging.

Honestly if you don't have a specific reason to target iPhones then buying a 2nd hand Pixel 8, putting GrapheneOS on it then pushing an "app" in whatever language you want on it, sure can be Java but can also be Python, Julia, whatever you want really especially on it directly using Termux, could be a better use of your time. By the time Xcode starts you'll already be outdoor testing against the next transformer.

muster and muster-pattern-library. (https://github.com/azide0x37/muster)

an agentic coding scaffold/framework you can reference when building out your next random raspi project. prefer to build around systemd units first; make an idempotent installer script, then put as little as possible custom coding around that.

`impl muster` comes down to: /build out this tool wiring together `patterns` like: C3.dropfolder-trigger; R2.device-binding; C4.lazy-resource-gate

or composite patterns like:

T2R4.device-triggered-conveyor "Bind a physical device event to a bounded ingest job that waits for hot-storage capacity, proves cold-storage capability, stages local work, and hands output to a hot/cold conveyor."

I need to back up a couple hundred DVDs, so with muster I get out:

dvd-ingester T2R4.device-triggered-conveyor

Architecture DVD media becomes ready -> udev rule adds SYSTEMD_WANTS=dvd-rip@%k.service -> systemd runs /opt/dvd-ingester/current/bin/dvd-rip-one /dev/%I --apply -> dvd-rip-one proves DEST_DIR and waits for HOT_DIR capacity -> completed rip moves to HOT_DIR/<run-id> -> dvd-publish-one.timer drains HOT_DIR to DEST_DIR -> publish writes DEST_DIR/.incoming-<run-id> and atomically renames final output

Pipelined; ejects after rip completed. Monitors local disk capacity, retries after NAS comes back online; resumes after random reboot; etc.

Closing up work on my modular, hobbyist, analog computer. (Finishing up the manual—the hardware is already a wrap).

Something I can finally enjoy: just playing with it. I tediously wired up a pair of pendulum simulations to drive an XY oscilloscope—got a nice Lissajous curve.

But now I want to double it to four pendulums. Each axis (still just X and Y) to be driven by the sum of a pair of pendulums. With them out of phase, the curves appear to sometimes collapse but then suddenly explode again…

(Love to eventually hook it up to an actual plotter.)

Fitting lines to 'xray' scans of buildings - turning pixels into vector art.

Lets say you have a complex industrial plant, or datacenter you want to upgrade.

You scan it with lidar and get a pointcloud and 360 panorama images. This gives you a large dataset, but what you really want is a floorplan, a lite CAD plan showing the racks, cable trays etc.

You take the scan, slice the pointcloud and make an ortho image .. it really looks like an xray of a building from the top down.

Then someone has to manually trace that in CAD to make a useful 3D model they can use for designing the upgrade.

So Im automating the boring manual part - turning the xray plan pixels into vector polylines, using machine learning.

One of our clients scanned their datacenter, and we generated a floorplan that shows all the rack box positions, cable trays, pipes etc.

Other examples : drawing the weld lines of patches in steel storage tanks, drawing in all the steel girder beams in a scan of an old railway bridge, or the windows, doors, ceiling pipes of a commercial realestate refurb.

haritha-j2• 2 months ago

Interesting, so you process the point cloud purely in 2D slices? do things like vertical piping cause any issues? or is 2D enough? I'm just finishing up a PhD in modelling industrial spaces from point clouds so I find this space fascinating.

jgord2• 2 months ago

imo, 2D is maybe 70% of the problem to solve. We build and we think about buildings in 2D, possibly because its simpler/cheaper, possibly because of gravity corraling us into spaces with flat levels.

Computationally 2D is simpler, less dof, also conceptually. I decided to bring the scope in to get some wins on the board and early revenue.

I did do a lot of prior work in pure 3D, detecting walls and pipes :

  https://youtu.be/-o58qe8egS4
  https://youtu.be/8fjHNDGKeu4

ans also have some demos of fitting textured triangles to make lite 3D web browser models .. a while before gaussian splats came on the scene.

You are quite right, pipes do bend and jump thru 3D in complicated ways - and so flat slices only pick up part of their journey.

My rationale is most people want an accurate floorplan first, and quickly, and this saves time and captures much of whats needed.

Obviously the same 2D technique can be used in sequence - floorplan first, then get a slice of a wall, and get vector lines for all the door and window openings, or the stairs using the same process [ pointcloud slab slice -> ortho xray image -> vectors -> CAD ]

I've been working on a newish variant of Sudoku called Binku. It combines the traditional Sudoku rules and adds the rules from a game called Binario/Takuzu (with 1-4 as one color and 5-8 as the other color).

A sample puzzle can be found here: https://sudokupad.app/23x300ggzn

It's been well received by the (very kind!) Sudoku/puzzle communities, so I'm working on throwing a nice interface on it that fits the rules a bit better. I've found about five other examples of others doing a variation of this ruleset before in one way or another, and it's been fun trying to see how hard/deep I can get this puzzle to go.

I got let go back in March, and since I've pivoted into building a game. In the 3 weeks leading up to unemployment, I had gotten way more into an old GBA game I used to play back in the day, Harvest Moon Friends of Mineral Town. The (remake of the) game that inspired Eric Barone to make Stardew Valley. I was bumping into the same in-game limitations of the cartridge and platform that always made me want more from it, (and while Stardew Valley was nice, it never fully scratched that itch) and as I found myself unemployed, I found the mental space to start building.

The game is going to be a farming tycoon/city builder game where you can buy farm stands and advertise to sell your goods. As your operation grows, you grow the local economy and people move to the town turning it into a city, opening up the chance to sell at farmer's markets or supermarkets. As the city grows you'll have to buy/sell land with the city and work with the mayor to plan where the city should claim new land for you to purchase so you can stay on the outskirts with healthy soil (or in the endgame, run for mayor and manage the growth of the city yourself, a la Sim City/Cities/Frostpunk)

I chose Love2D as my engine so I can use the relative simplicity of 2d art in 2.5D pseudo-3D instead of 3d modeling. The world space is a 3d euclidian grid of cells wrapped around a horizontal cylinder on the x axis. The view space is perpendicular to the side of the cylinder, giving us a natural horizon at the vertex of the cylinder on screen. The world space coordinates are expressed in terms of the polar coordinates of the cylinder, giving natural rise to radius as altitude, angle theta as latitude, and x axis as longitude. All the world math can be calculated using the trigonometry of the unit circle, and converted to 3d Cartesian coordinates before converting them to screenspace coordinates. I can use regular flat plans and elevations for the texutures of building faces, and render them upon linearly transformed quad polygons. Maybe I can also do some screenspace displacement a al Crimson Desert at the finish line to give buildings window sills and ledges when you see down a side of one.

I am doing the development without LLMS as much as possible so I retain a good grasp on Logic, Language, and Math. I have been having a lot of fun digging back into these multivariable calculus and linear algebra concepts I thought were beyond me (because of some autobiographical amnesia issues I deal with) to discover that no wait, I was taught these concepts in high school and was quite comfortable applying them. All the development is done on my own private, secured git instance on my homelab server and I can pull down the latest revision to my iphone to show off, it's been really cool. Kind of a pita to find a good git app on iPhone that allows custom git servers with ports though.

screenshot of a very early hello world, before I made the mental connection between wrapping a 2d cartesian plane around a cylinder and actual 3d cylindrical polar coordinates, which is why the shapes just sit over the world rather than extending from it, I hadn't yet conceived of the radius of the cylinder being altitude: https://fucci.dev/assets/helloworldspace.png

helloakariq3• 2 months ago

Great question. Cheaper prices come from a mix of focus on customer value primarily. That includes making sure that the eSIM is high quality (low latency, data routing in the region) and also focusing on getting the best eSIM plan to the customer - transparency, better FUP etc. So there's an element of optimisation involved here.

Tell me more about the tracking code

marking-time5• 2 months ago

From the "Manage Bookmarks" applet within Firefox[Menu|Bookmarks|Manage bookmarks] choose the "Import and Backup" option at the top of the applet. Choose the "Export Bookmarks to HTML" option and save the file. This will create a HTML file on your device containing all your bookmarks.

Open the HTML file in a code/text editor. Look at one of the anchor tags and you will see the contents of "HREF", "ADD_DATE", "LAST_MODIFIED", "ICON_URI" and "ICON". Only the "HREF" is necessary to make the anchor tag functional. All of the others serve other purposes. Most of the others makes some sense, but seem obsessive to me. The longest, sometimes hundreds of characters long, is the "ICON" item. That long string of characters concerns me and looks suspiciously like the traffic I see when I use network monitor inside Inspect. To me it looks like a tracking code.

Of course I may be wrong, but none of that stuff is necessary except the HREF. The script I wrote strips off everything except the HREF, puts it in a new anchor tag, and it works fine. Really this is just old school HTML.

Thank you for Tiled Words which I play regularly! I introduced it to a couple of friends and now they compete every day for the best time to finish :-)

While you're here if I could make a small suggestion - the wording of the 'type of' questions was confusing to me until I got used to it; 'stop' is not really a type of 'watch' for example, so maybe you could find a different way to phrase those? Maybe there isn't a neater way to encapsulate the idea of 'is a prefix or suffix to', I don't know, but I found it difficult. Anyway kudos to you and your wife, it's a great game!

paulhebert14• 2 months ago

Hey, that’s awesome, thanks for playing and sharing it!

Great feedback on the “type of” clues. I’ll need to noodle on that and see if there’s a clearer way to express it. Maybe I should just be doing blanks… e.g. for “sun” it could be “___ dress, ___day, or ___ flower”

codebje4• 2 months ago

To me a "stop watch" is a type of watch, that's straight forward. But there are other clues that rely on cultural references I'm not familiar with - and that is, I think, inevitable in this type of game. We all have different backgrounds and there's no universal shared understanding that would make every clue the same difficulty for everyone.

I saw someone on here recently say they like to do the puzzle without looking at the clues, and I've started doing that on and off too, it changes the game in an interesting way.

I've been playing this since it was first mentioned on HN a few puzzles in. It's a nice idea and pretty well executed.

I have, however, rejected making a user login. I recognise you're putting in time and energy to make something I'm just taking without payment, and it's your right to try to leverage it into something more - I wish you all the best in doing so - but asking for a user login as a gate to a feature you clearly don't need a user login for is enshittification.

paulhebert14• 2 months ago

Hey, thanks for the feedback. I didn't intend to pressure you to create an account. Sorry if I gave that impression.

I'm guessing you're referring to the ability to filter out completed puzzles from the archive? I added it for logged-in users first because it was simpler but I can extend that feature so it's available for everyone. (I'll need to add some alternate logic to pass your indexeddb levels to the server endpoint when fetching the archive. It's not complex. I just haven't prioritized it yet.)

I'll add this to my backlog and try to get to it after the player puzzles release.

Beyond that everything is available regardless of user account right now. I do plan to require an account to submit custom puzzles when that's released. (Mostly to make moderation easier. I may relax this down the line.)

EDIT: On further thought I realized it's also required to have an account to view and share your profile stats, though that could also work without an account with some changes.

* Tab Wrangler for Chrome: https://chromewebstore.google.com/detail/tab-wrangler/egnjhc...

Continuing to work on Tab Wrangler, an extension for both Chrome and Firefox that has been available and open source for 10+ years. It auto-closes tabs when they have not been active for a configurable amount of time, similar to the feature built into Mobile Safari but more configurable.

I have been maintaining it and in the past few months added features that had been requested for a long time.

I'm currently working on BetterCapture (https://github.com/jsattler/BetterCapture), which is a lightweight (~4MB size and low memory/cpu footprint) screen recorder for macOS that lives in your menu bar. It supports ProRes 422/4444, HEVC, and H.264 — including alpha channel and HDR. Frame rates from 24 to 120fps. System audio and mic simultaneously. You can also exclude specific things from recordings, like the menu bar, dock, or wallpaper.

No tracking, no analytics, no cloud uploads, no account. MIT licensed. Everything stays on your Mac.

I'm currently planning and designing a plugin system, so others can contribute new functionality without affecting the scope of BetterCapture itself - which should stay as small as possible.

BrowserBox demos: https://win9-5.com/demo

These embed a remote browser in an iframe to give you “embed anything browser view” custom elements. The demos focus on retro desktops to emphasize the browser - as these common web tropes, the retro desktop, can never actually ship a real browser without something like bbx.

https://browserbox.io https://github.com/BrowserBox/BrowserBox

adikso2• 2 months ago

Maybe I'm slow, but tbh this "retro desktops" demos were more confusing than helpful for me. I had trouble understanding what are you trying to show with this - why is there a full desktop with multiple apps, and it takes several clicks to open this web browser. "embed a remote browser" and "embed anything" in the same sentence - anything? Like are they embeding streamed windows 95 os? Is this entire windows simulator streamed (too good quality but could be some streaming svg magic)?. Too much irrelevant details and elements. Obviously I understood after these several clicks and seeing heavily compressed browser window, but I found Hyper-Frame browser to be a clearer demo.

keepamovin2• 2 months ago

Thanks you for looking and for sharing.

Hyper-Frame is supposed to be the "developer" demo that engineers will understand what they can do with it. I think it succeeds at that. I'm glad you found it useful.

The desktops are more labor of love, nostalgic, imaginative. I grew up in that time. They complete the "art" of web desktops by giving them internet access, which otherwise all omit. I don't care that they bury it seamlessly rather than making it obvious. I like that it's integrated as it would be in an OS, that's part of it. Your point is accurate that they do not surface bbx obviously.

So these desktops and glitch are more meant to spark imagination, maybe prompt product ideas for people who could be inspired by that. It's supposed to, I suppose, work subliminally, by letting you play around with it in an immersive setting. I suppose it's a different buyer profile or purchase stage they are meant to be honey for, not the "give me what I want now" seeking, but the more playful, relaxed, idea-sparking stage/persona. It's meant as an art gallery :)

You probably got annoyed doing it - that's okay, it's probably not really for you.

I feel the set of demos taken together cover the things I was wanting to express about this. I'm very happy with them - both individually and all together.

Thanks for looking - and for your great compliment - yes windows is all HTML, notice it says Windows 98-and-a-half ! :) They are also really just meant to be fun, and I had fun creating them. And meant as a show off lol :) - I like it when people enjoy a beautiful time playing around with them.

motoroco3• 2 months ago

I wanted a faster, easier mapping app to plan motorcycle rides for myself and with groups, so I finally bit the bullet and started building my own at the beginning of this year.

I got to the MVP state which was useful for my personal use case in about a month. I took it further than that as a learning exercise and as a means to share it with others. Some features that came later are live cursors (like Figma), elevation chart and grade overlay, and QR-code enabled collaboration links to make in-person sharing simple.

Check it out! https://plotalong.app

Figuring out the exact UI/UX I wanted was the hardest part. I did the branding myself, handdrawn on paper, traced in Procreate, and vectored in Sketch. Fast iterations and a good test suite made it possible to try lots of different approaches and refine the one I liked the most. There are roughly 4000 unit tests and over 300 e2e tests that run on multiple environments with fully automated CI/CD.

I’m using Mapbox for the frontend and the whole app is basically just a monolithic Cloudflare Worker. Claude pretty much implemented the entire thing. I got a lot of mileage out of self hosting a Gitea project and recording all my planning sessions as Milestones and Issues. Claude has his own account without admin privileges. The process of managing a team of agents to build this practically autonomously was a bit jaw dropping and eye opening to be honest.

I would love to hear from other pleasure & sport drivers about the features they use or want the most in a routing app. I have an Android app in Play Store review, if you’d like to be an early access tester shoot me an email at my handle @plotalong.app

danparsonson7• 2 months ago

Very nice! Does the sharing feature allow live location sharing? That seems like it would help a lot, especially when group members are in separate vehicles.

motoroco3• 2 months ago

No, and while that does sound like a pretty obvious feature I should clarify the app is about planning, not turn-by-turn directions. You can open Plot Along routes in Google Maps, Apple Maps, multiple GPS formats and more

The idea is everyone opens the same route for coordinating and there’s just one source of truth for the group. And then when you’re all about to hit the road, everyone can use the nav app they’re already familiar with (or that’s built into their vehicle)

I will tackle the navigation aspect at some point if I do keep up on feature dev, though!

I've been working on a pure Clojure implementation of WebRTC Data Channels (SCTP over DTLS over UDP). The library provides a minimal, dependency-free (except for Clojure itself) way to establish peer-to-peer data channels on the JVM.

simonpure2• 2 months ago

Thanks! I've noticed a big jump when they switched to Gemini 3.1 Pro and it really became useful. I like that I can use it from my phone too. It took a bit of trial and error but I came up with a good ralph loop between GitHub Actions and Google Jules using the Jules API. So basically I have Jules extend its TODO.md with the next set of tasks and open a PR then run a GitHub Action with a few checks, auto-merge, and then call back into Jules to kick off the next cycle if there are still open tasks. It then mostly just runs and occasionally gets hang up on some questions that I then answer on my phone mostly just telling it to make a judgement call and keep the build green. You can check out the prompt, action, and past PRs for examples ex. Jules prompt is here: https://github.com/alpeware/datachannel-clj/blob/main/prompt...

I’ve been working on Broadcast since Sept 2024:

https://sendbroadcast.net

It’s a self-hosted email marketing/newsletter app. The basic idea is: own your subscriber database, run the app on your own server, and send through SES/Postmark/Mailgun/SMTP instead of being locked into another SaaS.

Not trying to be “Mailchimp but cheaper”. It’s more for technical founders, agencies, and consultants who want a boring, controllable email tool they can deploy for themselves or clients.

I’ve kept the changelog public because I wanted the work to be visible: https://sendbroadcast.net/changelog

My buyers are typically people who want to own their data and are in regions that have strict data privacy regulation/laws.

I've been working on an update to my flashcards app for over a year and half now and I'm finally nearing completion. This is for Mac and iOS only and the app uses Core Data with CloudKit for syncing its data, which has been interesting learning the ins and outs of. (For instance, CloudKit can throttle your sync if you have too many objects, so I ended up having to create snapshot objects to carry lots of records in bulk which I then expand in a local SQLite database to get around its limitations.)

The app has a lot of UX details that I've really enjoyed working on. I wrote up some notes about it here: https://www.freshcardsapp.com/3/

Separately, also working on a Zettelkasten notes app that pushes you to make small, atomic notes that you can organize in "collections" to provide structure beyond just hyperlinking in the note text: https://understory.ussherpress.com/ This has been a lot of fun iterating on. I started with a Miller Columns UI, like Finder, to visualize the graph of connections between notes, but I found that it was too overwhelming to use, so I scaled back and went with a more Notational Velocity-like quick search bar with note addressing. The app UI mimics a browser because I found that it works really well for something like this. I need to polish it a bit more and want to find people who will give it a beta test to help me iterate on the ideas some more.

You can also filter the streams by type of place or features, for example beaches or cams with audio. And if you don't know where to go, just try out the Explore button.

I'm working on requested features for my social wishlist app https://thingstohave.app: image uploading, passkeys and more clear list organization UI. Everything is in polishing stage, and I hope to release these before June.

Big thing I made recently is moving it from SvelteKit to Hono + Inertia + Vue.

I like SvelteKit, but I was struggling with stability in active development periods, and writing proper tests was very hard due to mocking all the magic, especially outside trivial testing tools.

Now the whole app is straightforward Hono MVC with Vue powered UI. Logic is easy to test, and all UI states exposed in Storybook.

I wrote a custom adapter that makes Inertia run on Hono, and coincidentally same thing was released by Hono author itself as official module, which is great sign for adoption!

So, try Inertia – it is a best of both worlds. You write MVC backend as you like, and use modern JS frameworks for templates.

* This is my first time actually posting anything on HN.

I've been making a DSL for writing sheet music specifically for drums as raw text, inspired by ABC Notation (but of course just for drums).

Now writing this I noticed that it's kind of complicated to explain and having a landing page would make my life so much easier.

But the gist of it is, you write notation that looks like this: https://gist.github.com/Luigi123/945af7e5cc8dfbfd186f0a99754... and it renders sheet music in PDF, and also allows you to play the same music as a game (DrumMania / DTXMania style).

Now the language / compiler itself has been working quite well and I've been dogfooding it for like six months now. The next thing is an IDE-style editor where you can import a song and write the notation following it. Making THAT has been quite the journey. Here's a screenshot for good measure: https://i.imgur.com/EmlqlrM.png

oo interesting.

is this intended for drummers, or electronic music composers?

luigi_1237• 2 months ago

It's intended for drummers, but I wouldn't rule out anybody. It can generate sound, and I'm even using some nicer sounding samples I found on the internet, so using it for composition is realistic.

But the main use case I'm going for is my own: making sheet music for drum practice.

kukkeliskuu7• 2 months ago

Maybe 10 years ago I started to build Guitar Hero style game with real electric drums, initially to teach myself drumming. The idea was to extract drum information from real songs (so I was exploring a DSL as well). I guess modern AIs could be used to implement this much quicker.

sbrother• 2 months ago

Oh dude, I love this. I've been working on an interactive music thingy (https://trebel.la, it's sort of gamified but more designed to structure practice sessions for serious classical musicians) and struggling with the ABC vs. MusicXML choice.

Like most people in the space I'm using ABC for LLM generation (e.g. generating sightreading exercises and etudes) but MusicXML for processing and rendering the output. Would be nice to have something somewhere in between the over-simplified ABC and overly verbose MusicXML.

luigi_1237• 2 months ago

Would be nice to have something somewhere in between the over-simplified ABC and overly verbose MusicXML.

Hard agree.

Early on I actually tried to write my drum charts directly in ABC Notation but it wasn’t a great fit. Then I made a simple parser for my language that outputs ABC because I thought it would be simpler but I found it to be very limiting, so now I use Vexflow’s low level API for rendering. I found it to be more customizable than ABC with a nice JS / TS API. It’s good for my use case (rendering) but ofc it doesn’t work as a save format.

Good luck with Trebella :)

I love this. This was always an idea I had in my head, because spinning up MuseScore just to write down some beats was so annoying. Glad someone already came up with the solution! Do you plan to release the compiler(uh, rasterizer/renderer)?

luigi_1237• 2 months ago

Yes, having to deal with MuseScore was one of the reasons I started to work on this. I'm glad you picked up on it.

I definitely want to release it as an open source project, but there's still quite a bit of stuff left to do before I can. The biggest blocker is copyrighted material. There's a ton of copyrighted material in the test suite (oops), so I need to clean that up before releasing.

Also I want more demo songs that are not copyrighted before releasing, and so far all the songs I notated for myself are copyrighted, so that will probably take a while as well.

Also the IDE-style editor needs a lot of polishing before I'm ok having other people use it.

There's still a lot of stuff in the language itself I want to decide (what if I wanted to change time signatures in the middle of a song?), but I'm okay with releasing the project before that stuff is done. The two biggest things I have to do before thinking of releasing this is getting rid of copyrighted material in the codebase, and polishing the IDE. But I definitely want to release it!

I am a beginner-intermediate so lots to learn for me. I use musical notation. If anybody interested in it let me know.

meltmymind• 2 months ago

Very cool. I'm working on something similar, for composing songs with both note-playing instruments and drum instruments. The format is TOML-based, and for melody I was inspired by strudel, but I had considered using ABC notation as well. The home page has an example of the format, and some demo songs: https://songformat.com

luigi_1237• 2 months ago

Your TOML-based syntax is really interesting.

"drums: (bd ~ sd ~)32",
"drums: ((hh@0.5)8)32",
"drums: (cr@1 ~@15)8"

I definitely considered stuff like that but in the end decided to have every note spelled out. I might reconsider though! Right now it's really annoying to have reaaally long lines of `kd/2` ad infinitum to write double bass.

I'm split between three options right now:

1. Just add multipliers like you did (`kd/2 * 16`), but I feel that makes it less "music" and more "program".

2. Special syntax sugar just for well known patterns that are repeated in many songs, like `dkdk` expands to a full bar of double bass, or xxx expands to one full bar of 8th notes on the hi-hats.

3. Have the user define custom pattern on their own, like `xxx = x x x x x x x x`, like C macros.

It’s a hobby project in a very early state where it technically works but it’s missing several things I think it needs before I’d use it for anything serious.

The author of FizzBee reached out to me about a year ago on LinkedIn actually, because I gave a talk on TLA+ a few years ago.

I haven't really played with it yet (outside of the few examples on their site) because I'm already pretty entrenched in the TLA+/PlusCal world, but it is very likely that FizzBee might be a better fit for software engineering circles; the incremental testing is pretty neat, to a point where I kind of want to steal the that and port it over to TLA+/TLC. Probabilistic testing seems pretty cool too.

If I were getting into Formal Methods today for the first time, I would almost certainly be using FizzBee and/or Alloy.

westoncb• 2 months ago

I've been building this "general problem solver" (will likely focus on math problems first) that uses a special kind of orchestrator to direct/structure the problem solving approach in accordance with how many 'rounds' remain and other aspects of problem context. It does this largely by influencing the behavior of specialists.

Just posted a first early demo and sample orchestrator system prompt yesterday: https://x.com/Westoncb/status/2053429329233895857

You initialize the system with an objective and a number of rounds to run for, and it loads the current config (orchestrator + specialist prompts and LLM configs) and begins working on it. You can manually step one round at a time or just let it run.

Rather than accumulating a single long work log/context, at each round specialists apply patches to a number of named 'artifacts' with different roles (e.g. uncertainties, dead ends, findings), which are injected into prompts during subsequent rounds.

The engine is written in rust and there's a web UI (and CLI). You can use the built in config editor to define specialists (and their prompts), what the artifact set is, orchestrator prompting etc.

my embroidering is going fairly well now, but i need to be able to figure out what floss to buy.

the general idea is to take pictures of birds and mountains, and use a bunch of colour-theory-from-minecraft

to first meanshift a bunch of the image to come up with a lower colour resolution image, then to match that to dmc threads

but then i also want to use tools like the axiom mod to fill in gradients, and to do hue shift/temperature changes to represent shadows, like how bdouble0100 uses purples as a shaded green, rather than a darker green.

ive also been using it to see how the claude code for web setup works, and it feels real poor compared to the cli.

the main problem i think i need to pull to local and do my own code for is the colour sampling from the oklab space. when i try to create gradients from colours already in the list, i ve got a visualization of the line its aiming to follow, but its picking the next colour and placing it out of order vs projecting to the line.

likely my biggest issue is that claude and the like are still bad at thinking in more than 2 dimensions, but i think my vocabulary is also subpar for giving the feedback either in clear linear algebra or colour theory terms.

next idea is for when thats done is to make a mod that turns a survival game into a roguelike - in the style of the hades 2 challenge runs, so i can play a session of the game in a certain biome without having to do all the grind first to get there on a new character.

I’m developing X/D Loom (https://xdloom.com), a tool that helps car enthusiasts create automotive wiring diagrams.

About a year ago, I engine-swapped my Nissan D21 hardbody from the Z24 petrol to a TD27T turbo diesel and also installed a whole bunch of accessories, like spotlights, a winch, and an air compressor. But being lazy, I didn’t write down any of the wiring changes I made while doing all of this. So fast forward a year, and now I can’t remember how all the wiring works.

My current project car is a Jeep Cherokee FSJ, and for it, I want to build a completely new loom from the ground up. So to try and avoid making the same mistake I made with the Nissan, I Googled “create automotive wiring diagram”, but all the results were for complex enterprise grade solutions charging $200/month. That’s why I created X/D Loom as a project car guys' tool for creating wiring loom diagrams. It allows you to drag different electrical components onto a canvas, connect them with wires, and export them to a PDF or PNG.

Since you're trying to product-ize and might want to expand the market a bit... aviation might be a nice market. There's a whole culture of people who build light general aviation aircraft under the "experimental" class of aircraft.

Most kits come with wiring suggestions for standard things like fuel pumps, lights, etc but once you get into avionics the options are essentially limitless. A quick Google search has a few reddit threads of builders talking tools and it ranges from AutoCad ($$$) to some type of drawing software like MS Visio.

The only possible unproven alternative is adopting the one-hour token generated by Apple which goes through ADP, but assuming that even works, that defeats the purpose of the app being more than a one-shot.

https://toanoa.com/

Since the initial MVP, it's done close to 100k orders and I've added new functionality like:

- Intelligent order batching & route optimization that can interleave tasks across orders in such a way that they still have the best chance possible of completion within their delivery windows

- Further refined the mobile tracking logic in our driver app to improve the quality/frequency of position updates while continuing to be as efficient as possible on battery

- Numerous backend/DB optimizations such that average response times are in the tens of ms at the current volumes it's handling.

It's not open source but if you have an interesting use case and are curious about it, feel free to reach out.

This starts from my frustration when opening large CSV files, but later evolved to a log/data analyzer that loads arbitrary format in constant time (O(1)).

https://github.com/Verticalysis/Hitomi

The secret: I engineered an incremental combinatorial parser capable of processing customized format from a steam. Any inputs, including file or the stdout from a command, are first chunked and then fed to the pipeline. The UI is ready when the first small chunk is processed.

Other highlights: 2-mode filter, one with a convenient UI and the other is based on an extensible DSL for complex cases;

Timeline mode scrollbar, a secret weapon for log or time series analysis;

Column widths fit to content automatically;

Native code, no web bloat;

Cross-platform (currently Windows and Linux, MacOS WIP).

If you are tired of all the quirks Excel have when working with CSV files, you'll gonna love it!

Does it update the parser incrementally?

SdtEE2• 2 months ago

I'm not sure what do you mean by "update". If you mean the state of the parser - of course, and I did some trick to reduce the supposedly infinite states for arbitrary format to a fixed set of 4. If you mean by the parser program it self -No. The parser was developed with Dart, a statically compiled language, with no ability to modify the program itself.

With AI IDEs, Personally I had to generate a tons of md files for planning a task, analysis on the code for something or other, a task doc for a feature - a summary to paste into the clickup ... and I saw many devs keeps on generating them, and all tucked away into folders. Good, okay.

For the company I'm currently working I had made a VSCode extension where I can sync the task doc with clickup via frontmatter.

I decided to take it to next level as a side project. I built a CI integrated, git-native, agent template transformable syncing pipeline with git MD files to any project management tools. That means, either you can save your md files vanilla in your wiki (thus using the clickup AI search to dig up later, get insights etc) or you can use a AI agent template transformer to turn it into a task template (Background, acceptance criteria, functional requirements etc.) and update or create a task on a board.

I've been working on it now. I don't know how it will fare, but I feel like product is coming up nice.

I was actually working on last weekend with something that has similarities. I am working on USM.tools, which allows specifying your services in structured way.

There is a need to specify some of the data in semi-structured way, and I am using markdown for that.

So there is this interesting relationship between unstructured, semi-structured and structured data, and markdown hits that middle ground.

Can I suggest you make some Jira etc. templates on your landing page clickable, so a visitor can grasp your idea more easily? For me it was not clear whether the specs are just plain markdown, or do you have some additional tagging there.

I have fully implemented mutable torrents (BEP 46) in Transmission. When a torrent is created, you can set it to be "mutable", and you (and you alone) can add files to the torrent, remove them, modify them, or change their filenames. Other members of the swarm will be notified of the new change, and begin downloading that as well (if they use a client with mutable torrent support). For leechers, they can choose whether to allow mutability on a per-torrent basis, and only in the fashion that they prefer. They can even store every change (and seed those) too.

I have the macOS, Windows, cli, and web app working with this feature. I had a bit of a mixup with Gtk, so I don't have a Debian package for it, but it's buildable from source.

I’m really interested in AI4MATH, as I believe it will eventually replace me.

I'm working on a mathematical knowledge base software.

It's kinda like a local Github for math. In fact the backend is actually a Forgejo instance, I'm building a frontend for human and also a harness for agents that automatically consumes the knowledge base and expand on it. I realized the Issue/PR/review workflow works well for maintaining knowledge base too.

The motivation is actually help mathematicians/me TODAY to able to do math together with human/AI.

The knowledge base keeps mathematical writing as plain Markdown, but adds stable IDs, backlinks, search, draft changes, review, approvals, and merge. The agent side can read the same pages, follow the same references, propose edits, and go through the same review process as a human.

I’m not using formalization here. Everything is still natural-language proofs. The practical reason is that many areas I care about are not easy to formalize yet because it is not in mathlib.

I see this as a transition project: useful before autoformalization really works well, and maybe still useful afterward as the place where humans and agents organize exploration.

I'm building a memory safe programming language that's like Rust, with a declarative concurrency model, which makes it much safer, simpler, and easier and nearly as fast & efficient

https://github.com/cuzzo/clear

The goal is to make Rust code nearly as easy to write as Ruby, but it almost always does the absolute best strategy.

You can write somewhat slow untyped code, and the internal tooling can guide you to adding all the types and optimizations and concurrency strategies that will make your code as fast as possible.

nateb202213• 2 months ago

Sounds a lot like Crystal, which is also similar to Ruby and features a green fiber runtime: https://crystal-lang.org/#concurrency

onlyrealcuzzo2• 2 months ago

Yes, in a lot of ways.

Crystal wanted to be Ruby/Go - essentially a faster Ruby, that sort of scales, too.

CLEAR aims to be a substantially safer Rust - no Garbage Collector - no manual synchronization hazards, and safer than even Pony - but also with far less complexity than Rust.

Crystal's fibers did not do well multi-threaded until somewhat recently, and AFAIK, it's still very far behind Rust/Tokio and Go in a lot of important benchmarks. Crucially, afaik, p99 in adversarial workloads can still blowup easily.

Like Tokio, CLEAR lowers fibers into Finite State Machines instead of stacks, which perform better than stacks in wait heavy (i.e. Go's primary market - web servers) and idle-heavy scenarios (i.e. chat servers, telecom, etc), and it has Go's work stealing algorithm + forced yielding to ensure p99 doesn't blow out.

Also, CLEAR transpiles to Zig, so it has native access to the entire C library. Crystal has a bootstrapping / ecosystem problem that's unlikely to ever be solved.

CLEAR doesn't need a single person to contribute to it to have access to basically everything.

Also, transpiling to Zig means you get Zig's other killer feature - you can compile to any target (i.e. Linux) from any target (i.e. MacOS).

I've been learning to crochet. I'm trying to do more hobbies with my hands, but it's also pretty interesting from a mathematical perspective. The fundamental primitive (the chain stitch) is like a series of slip knots, and each stitch is reversible. So the piece is actually a series of reversible transformations. The yarn is sewn in at the end to secure it.

This has some interesting implications. If you make a mistake, you can always backtrack and try again. If you have a crocheted piece, at least in principle you could find the lose end, free it, and work back stitch by stitch to reverse engineer it. (In practice people don't seem to do a stitch-for-stitch reverse engineering just like you probably wouldn't bother reimplementing something line by line without a compelling reason, you figure out what's going on in the challenging places just by look and feel and improvise from there.)

I'm oversimplifying somewhat and there are some forms of crochet that include irreversible stitches, yarn can be felted together (entangled, like a cotton ball) to create irreversible bonds between adjacent strands, and often several panels/pieces are joined together irreversibly to create a larger piece.

maxbond2• 2 months ago

I guess I should be clear that by "irreversible" I mean a transformation like the following: "to cut the yarn with scissors, to untie a knot that was strongly bound, or to felt together." So a slip knot is "reversible" in the sense that if you tug on it, it easily comes undone, whereas an overhand knot would just get tighter. You can think of felting as being equivalent to tying a lot of overhand knots between adjacent strands, they become permanently attached and could only be torn from each other.

I don't understand crochet yet but love the math of weaving symmetric patterns on a loom. I somewhat understand the absolute basics of a knit. I understand braids better. All from a pattern appreciation and puzzle solving point of view.

I'm still working on GridWhale.

My premise is simple: What if we could build a vertically-integrated, batteries-included, cloud-based development and execution environment that eliminated all the complexity of cobbling together a hundred different dependencies?

I learned to program in a simpler age, when programs ran on a single machine and had direct access to input, output, and storage. We didn't have to worry about client-server communications, or async storage calls, or idempotent microservice requests.

The reason we worry about that now is because modern programs don't run on a single machine anymore. They run on a distributed system with thousands/millions of clients (web browsers) connecting to hundreds/thousands of backend servers.

But what if we could build a platform abstraction layer on top of that distributed system? What if the platform took care of all the distributed complexity and the program itself didn't have to worry about that. From the program's perspective, it's just running on a big (abstract) machine. That's GridWhale.

Building a Sentry replacement that adds logs automatically and fixes any bugs it finds (https://superlog.sh).

The setup is done via one prompt ('Use https://skills.superlog.sh to install Superlog in this project'), and everything on the platform is usable via MCP so that you don't have to spend time configuring yet another UI.

kukkeliskuu7• 2 months ago

I really like this premise.

Recently I have had trouble with Sentry. I have a site that has a lot of data coming in (2M page views per month) and Sentry starts being unusable for a solo developer. And on the other hand, I have several Django projects where I want to have common way to handle bugs.

I am feeling Sentry UI is too complex for my use cases, and on the other hand, I would like to automate the process as much as possible -- and the idea of automatic bug fixing is neat!

I am experimenting with Bugsink. Supporting Bugsink internally but build some tooling around it for automatic bug detection and fixing would actually be a sweet spot for me.

nateb202213• 2 months ago

I like the premise but trying to be both the coding agent + the monitoring agent seems backwards. Your tool will mostly only be valuable IF it is the best coding agent out there. You're going to be competing against companies where automated PR agents are their sole product, and you're probably going to lose.

Do one thing and do it right.

Where I could see this succeeding is if you embrace the monitoring agent role. Customers can expose their coding agents, setup however they like, as an MCP server that your monitoring agent can plug into. If something goes wrong, your monitoring agent gives their coding agent the best context it can, and steps out of the way.

MacroCodex - Adaptive TDEE tracker

Most TDEE calculators only provide estimates. MacroCodex helps you refine those estimates to calculate a more accurate TDEE, which continuously changes based on your activity level and calorie intake.

Not only this, it helps you figure out when to lean bulk, cut, recomp. It automatically provides you recommended macro and calorie targets (which change as your adaptive TDEE changes)

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

I got back into MTG back during the pandemic after a long hiatus and Spelltable is what brought me back. My playgroup lamented more features and something tailored to our needs, so curiosity got the better of me and here we are. :)

I've never worked with computer vision before, but I went through a whole journey that started with the classical computer vision techniques and ended with recently migrating to the transformer-based models. Been a really cool adventure!

My playgroup has been consistently preferring it over Spelltable and have been wanting more and more features. I would love for people to try it out and start building a community around it! Discord is on the site.

https://cardcast.gg

borealbuilder2• 2 months ago

An alternative to spelltable is a great idea! My friend group played extensively a few years back through it but always ran into weird bugs and glitches.

I love that there is no sign-up required! Do you have plans to implement utilizing a mobile phone as a camera? Spelltables implementation leaves much to be desired.

Excited to see where this goes!

niothiel5• 2 months ago

Thanks boreal! I have it on my feature request list. I'm currently using a custom WebRTC + Websocket implementation for connections that I wrote without having this feature in mind, so reworking that will take some effort. Currently focused on client-side inference (runs in the user's browser), followed by continuous tracking (think: Snapshot the entire frame every 5s so all players know what cards are on the board at any given time). Will probably get to that in the next week or two!

If you ever want to follow along or play a game, feel free to hop on Discord (link on site)!

utopiah5• 2 months ago

Interesting, seems you are doing the recognition server-side, no reliable way to do it locally using e.g. WASM on the client?

niothiel5• 2 months ago

Actually actively exploring this very topic! I have a feature-flag version where the inference runs via WASM / WebGPU (onnxruntime-web specifically).

My only pause behind rolling this out further is the performance isn't as fast as I'd like (1.5s~ latencies), and the widely varying support for WebGPU / WASM across browsers and OS pairs.

Still testing it out (and learning about ViT performance on various hardware), so hopefully more news on that front soon!

ramon1563• 2 months ago

I had a similar idea, as alternatives were.. eh.

I also had an idea to get a ~12MP camera and set it up on an active game of MTG, just because standing up and having to read other people's deck was bothersome. My eyes are bad, and I end up not reading other people's cards because I feel weird hovering over them when reading.

I would then cast whatever is at the person's deck onto an app so I can manually read the cards. Since my phone is of a similar ratio as a playing card, I figured this might be a nice way to play.

niothiel5• 2 months ago

That's a really cool idea! I'm actually exploring a similar concept right now. On the demo page, I have a "Detect Frame" button which will attempt to identify all of the cards (as well as their bounding boxes). You can hook it up to a webcam to try it out that way right from the demo page.

Today, players have to double click on a card in a webcam stream to identify the specific card, but I'm working on doing full-frame detection on some cadence throughout the course of a match (think 1 scan every 5s so you always have an up-to-date board state, remembering past scans).

What would be super-helpful is to have a few frames from the camera or a video from your intended setup so I could test how well this scenario works. The detection is pretty good overall via webcam, it would probably work even better with 12MP.

I think this would be a really cool application. If you ever want to chat about this, I'd love to talk! Feel free to hop on discord (https://discord.gg/axRtvbsfAU) or DM me! (same username on both)

schipperai5• 2 months ago

A better permissions layer for coding agents. The tool works like auto-mode for Claude Code, so you can stay in the flow and only get prompted to allow or deny tool calls when it truly matters, but it is fully deterministic. My benchmarks surfaced that most Bash calls don’t need an LLM to be classified as safe, ambiguous, or dangerous. A deterministic classifier can auto-allow or block 95% of Bash tool calls as safe or dangerous, with only the remaining 5% being truly ambiguous or unknown.

Conclusion is permission reviews with LLMs like Claude’s auto mode or Codex auto review are like using a data center to flip a light switch - overkill.

The main benefit is that your agent’s autonomy can be governed deterministically through policies that can be stored at the user and repo level. The bonus is that you save tokens vs using auto modes.

You know I'd love an ability to a "lock" a file from being read by agents.

Does this tool solve that use case?

schipperai5• 2 months ago

Yes, you can define sensitive paths and assign 'ask' or 'block' policies to them.

.env, .ssh, and others are treated as a sensitive filenames by default.

Similarly, with hosts and network access - unknown hosts pause, trusted hosts can be configured.

Trilogy's model works quite well for agents, but I've avoided making AI features too native in the UI products - not everyone's cup of tea - so this month going to do a spike on a new pure AI native data authoring/exploration experience to see where that can go without messing with the core product, at both CLI/UI layers. Data consumption is (un?)fortunately a pretty perfect fit for the agent strengths with the right harness.

Lots of friends asked me which version of OpenClaw/Hermes are recommended as a stable version. I've no clue of it, and I don't updated my OpenClaw/Hermes very often to avoid unstable versions frequently. So I created the Agent Watch dashboard.

GPT would analyze each issue if it is negative. And also it would analyze if it the core features related issue. I iterated it several times.

It's a durable runtime for AI agents.

The thesis: agents should not just be an LLM loop running inside one Python process. Once agents touch real systems, you need crash recovery, retries, human approval, distributed tool execution, cancellation, observability, and execution history.

Agentspan is basically applying the Conductor OSS execution model to agents. Conductor made long-running distributed workflows durable. Agentspan tries to do the same thing for agent executions: give every run an ID, persist the state, let it survive process death, pause for approval, resume later, and inspect what happened.

A replacement for python.

- The base is a freestanding register VM deeply tied to the Linux kernel.

- It supports a set of primitives types, array types and record types.

- Concurrency is Erlang-ish --- an M:N scheduler that can manage tens of thousands of green processes. VM uses instruction fuel to preempt processes.

- GC is Cheney for the nursery + M&S for the rest. Each process has its own GC.

- tailcall support.

- first class functions.

- Phase One will only have Vm0, which is clean (it has access to a bounded set of Linux syscalls). Will think about Vm1 that handles the libc infection later.

- JIT is not on the table in Phase One.

- The language is statically typed and borrows syntax from python extensively, but drops OOP entirely.

- OOP is faked using UFCS.

- Operator overloading is supported.

- Exceptions are the default error handling mechanism. There are two hierarchies: Fault and Error. Fault cannot be trapped without rethrowing. Fault WILL crash the VM.

- It is being developed in private right now. As I am User # 0, all the choices I make reflect my own opinions and biases. I might release the code as OSS once the core is stabilized.

- I have done very basic microbenchmarking and the VM is so much faster than python right now that it is not a fair comparison anymore. I can also create and iterate over massive primitive arrays with ease. The principal comparison should be C, and here it is consistently about 8x slower and that performance profile will probably remain constant because dispatch has a real cost that cannot be magically wished away. I will be very happy with 5/6x.

I’ve split the experience into two parts: a mobile-friendly app at https://app.orcamarka.com for bookmarking websites, text snippets, or images into a pure text format, and a reader part at https://m.orcamarka.com optimized specifically for the limited browsers on devices like the Kindle (the site will automatically redirect you to app if it detects a more capable browser). To bypass the pain of typing URLs on E-ink, the reader part displays a QR code that you scan with the app to instantly sync and load your text.

I’ve been using this personally for a month and it has significantly shifted my long-form reading from my phone to my Kindle. Since it’s a web app, there’s no installation required and it's completely free.

osetinsky• 2 months ago

I’m working on Underscore: a web SDK and browser sandbox for making procedural music systems with LLMs.

The basic idea is "music with source code." Instead of prompting for finished audio files, you use an LLM to help write and revise a SuperCollider-based system that runs in the browser via WebAssembly [1]. The result is executable music: inspectable, editable, versionable, and controllable at runtime.

I’m especially interested in adaptive sound for software: games, creative tools, meditation apps, AI agents, interactive art. Places where a static audio file feels too dead, but hiring a composer/sound designer for every variation is unrealistic.

It’s early, but the thesis is that LLMs make algorithmic music much more approachable because code becomes a conversational medium. I wrote a longer piece about the idea here: https://x.com/osetinsky/status/2053674503801028944?s=20

You can check it out here: https://underscore.audio

All done in browser, no account sign-ups, no data transmitted to a server, and packed into a single HTML file so that the privacy and ethics can be viewed and verified.

Currently it covers 6 regions, 250+ subscription services, across 30+ categories, recognizing 850+ billing name patterns. It even has built in smart alerts for different services and region specific considerations. (FTC's Adobe settlement, Hola VPN Danger, UK Price Hike Exit Rights, Cloud Act Warning, etc)

It adds up monthly spend/annual spend. Identifies alternative saving opportunities/more ethical options.

I have plans to add additional regions but that will take extra research to understand the realities of those markets and the providers within them. I also don't speak any other languages, so this may also be a bit of a hurdle.

My partner and I got a 1 year old rescue schnauzer a few weeks back, so we are learning to dog while trying to teach her to sit, stay, and come.

Tech thoughts: this week I decided to move to a new to me NameBrand™ Arch distro. Even though I’ve been daily driving Linux for more than 10 years I still can’t get a new install up on the first try. This time the boot loader wouldn’t load. No error, no log, and no boot loading. A few reinstalls later, I picked a different choice and was finally booting. But then the next problem was the login display manager doesn’t want to sleep the monitor if nobody logs in. Learned this after an overnight power flicker caused a reboot. The monitors running full tilt for several hours waiting for someone to log in. While I would like to say this issue is another joy of the Wayland-way of Linuxing, I have found that other display managers offer the same defect.

Anyway dogs are great, I shouldn’t have waited so long to get one.

- ensure edges don't overlap with nodes to not obscure content

- ensure edges don't overlap with each other

It's about 60% of what my version of "complete" looks like. Remaining parts:

- edge labels (might need a rewrite of how edge paths are calculated.

- images in nodes

- generating diagrams for different screen sizes

I can monitor the status of my washer/dryer so I know when they are done (using cheap TP-Link Tapo smart plugs[2]). My favorite thing it does, is if any motion is detected on my Ring cameras, it just automatically pulls up that live feed. Took a little work to get decent playback performance but the pi 3a+ has hardware h264 decoding.

Its nice, overall, to have a little dedicated touchscreen on my desk that I can easily tweak to display whatever I want. Its silent and low power.

I'm working on Optio - an AI agent orchestration platform built on Kubernetes: https://github.com/jonwiggins/optio

It's built around multiple different types of agents:

- Coding Agents are placed into cloned repos with a ticket (Jira/Linear/Notion/GH), and work until they open a PR, are resumed on CI failures or github feedback, and work until they can merge the PR.

- Standalone Agents are reusable, parameterized agent runs with no repo checkout. Generate reports, triage alerts, audit dependencies, query a database, post to Slack, etc.

- Persistent Agents are long-lived, named, message-driven agent processes. Each has a stable slug, an inbox, and a cyclic state machine. Wake on user messages, agent messages, webhooks, cron ticks, or ticket events.

steve_adams_86• 2 months ago

Lately I’ve been working on https://oceanconnect.ca

The original developer has left our organization so I’ve been tasked with general assessment and winding it down to enter maintenance mode. It’s still alive and well, has a very passionate and appreciative user base, but we want to ensure it doesn’t demand too much attention moving forward while we focus on other things. It has pretty noisy error reporting.

Reliability and fault tolerance are some of my favourite things to work on in software so it has been a lot of fun so far. It has also been an incredible opportunity to practice using LLMs for specs, planning, verification, and research. I don’t actually need to output much code to get this thing into a stable state in which it can coast along; the bulk of the work is time spent understanding the app, the infrastructure, its existing faults, poring through traces and logs, going over query plans, and so on. LLMs are great assistants for this work and I’m having a ton of fun having so many opportunities to figure out what works and what doesn’t.

The outcome has been awesome. The performance is steadily climbing (especially in the database), and most common errors when I started are either gone or much better understood with plans to address them. I’ve almost got it set up so if someone needs to take it over in the future, it should be pretty easy to toss them the keys and trust that they can deploy and maintain it easily from the docs and systems I’ve created.

Despite spending a lot of my career on the front end, the hardest part of this project has been navigating that. Aiming to improve an application with minimal intervention is exceedingly difficult in the browser, or so I’ve been finding. I can get incredible performance gains out of Postgres without changing the interface between lambda and rds in the slightest, but meaningful improvements to the react application seem virtually impossible without substantial refactoring.

I understand the key factors in getting better performance out of react apps and I see plenty of opportunities, but they all involve large diffs that are risky and time-consuming, even with a model like Opus handy to churn through boring and large change sets. It’s such a fragile and flaky environment.

Even so, I’m loving it. Making software better is so gratifying. Doing it without reinventing the world is such a fun challenge, too. It really puts your brain to work. It would be so easy to go in and start flipping tables and throwing code in the garbage, but that’s too easy and too risky. Taking it slow, absorbing as much information as you can, truly understanding how features work, and planning surgical changes with significant pay off is safer and just feels awesome when it works.

I’ll be sad when this one is finished. It’s almost there. Next up is a remote temperature controller for 40 saltwater experiment tanks with a temperature profile planning interface and a monitoring interface for the lab. That will be awesome too. It has been a good couple of months for work.

Working on Vicena.ai, an agent to make scientists more productive, and make non-scientists into scientists.

- Integrated with lots of open-source and commercial simulators and models for chemistry, materials science, biology… As well as connections to service labs and robot labs to easily perform physical experiments.

- autoresearch / AlphaEvolve like optimization loop following the scientific method: observation, hypothesis, experiment, theory. Combined with a long-term self-learning memory like Karpathy’s Wiki.

You can work with it interactively like with a coding agent to research and execute experiments efficiently. You can also treat it like a graduate student, giving it long-term research goals, having it work 24/7, making smart decisions about where to use your limited resource budget, checking-in with it periodically as a supervisor to guide its direction.

Not all of this is shipped yet, but we’ve been online for a while and it should be plenty useful to any scientist/engineer already.

Working on fmsg - open protocol for instant messaging, distributed by domain like email..

Its a message definition and protocol, addresses look like @user@domain, anyone can run a host, and threaded messages are linked by cryptographic parent hashes..

The idea is to take the best from email: open protocol, domain ownership, interoperability (unsolicited mail is a feature not a bug), and the best from closed instant messaging rebuilt: efficient binary messages, conversational threads, sender verification, message integrity etc. built-in. Originally envisaged for human-to-human messaging but partculalrly interesting time right now with human-to-agent and agent-to-agent messaging...

The OSS stack is up and running: Go host, Dockerised full setup, CLI, Web API, and a spec nearing v1.0. Did Show HN post week ago: https://markmnl.github.io/fmsg/show-hn.html

Seeking feedback, criticism, validation :) protocol bikeshedding, and especially interest from founding-engineer types who want to help build an open messaging ecosystem rather than another closed app..

tgsovlerkhgsel• 2 months ago

What is the unique selling point that it has over Matrix?

Matrix addresses have a similar format, anyone can run a host, open protocol, domain ownership, interop... Threaded messages are supported AFAIK, the details of the crypto will be different but overall it feels like it is close enough that a new protocol will have a hard time having enough advantages to overcome the huge network effect (Matrix being one of the few open messengers that actually have some following already).

markmnl3• 2 months ago

You're absolutely right to pick up on that, I did study the landscape and Matrix is closest.. biggest difference is fmsg is just messages - group like chats evolve naturally in the threads - but to get a message someone has to send you one. Group messaging platforms like Matrix, Rocket.Chat etc have concept of rooms/forums/channels i.e. groups, then have HTTP APIs to manage membership and sync messages.. fmsg just messages someone has to send you

Also fmsg being its own protocol can do novel things like to auto challenge during sending back to sender - can't do that with HTTP

I’ve built SmallDocs (https://sdocs.dev; Show HN: https://news.ycombinator.com/item?id=47777633; live usage stats: https://sdocs.dev/analytics).

SDocs is cli (`sdoc file.md`) -> instantly rendered Markdown file in the browser

When you install the cli it gives you the option to add a note in your base agent file (`~/.claude/CLAUDE.md`, etc.). This means every agent chat knows about SDocs and you can say “sdoc me the plan when you’re done with it” and the file will pop open instead of you having to find that terminal session to know it’s done.

Going browser first means you’re not required to install anything to get a great experience.

Despite being in the browser, the content of SDocs rendered Markdown files remain entirely local to you. SDoc urls contain your markdown document's content in compressed base64 in the url fragment (the bit after the `#`):

https://sdocs.dev/#md=GzcFAMT...(this is the contents of your document)...

The url fragment is never sent to the server (see https://developer.mozilla.org/en-US/docs/Web/URI/Reference/F...: "The fragment is not sent to the server when the URI is requested; it is processed by the client").

The sdocs.dev webapp is purely a client side decoding and rendering engine for the content stored in the url fragment.

This also means you can share your .md files privately by sharing the url.

React + TypeScript with Vercel handling deploys, no backend (yet), the puzzles are just JSON. The toughest part is the puzzle generation: packing multiple snaking paths onto a grid like jigsaw pieces with the constraint that each answer has exactly one valid path. Coming up with good two-word themes has been its own challenge too!

Always looking for feedback or suggestions for improvement. :)

My friends and I went to Japan for a holiday a year or two ago. Every bar had an electronic dartboard and we all decided to get one when we got home.

We all did, only to discover that for the three of us we could either play 1v1 or 1v2 with one person having twice as many turns as each other person (and they would always win).

If you play on one board locally you can do 1v1v1. It makes no sense.

I have an esp32 syncing to the board and forwarding the hits to a client written in godot. I'm now spinning up the server for stats tracking etc.

I am working on a vs code extension for antigravity that will let me designate one thread as a "controller" and it can spawn and chat with multiple other agents in ag. I have a separate extension that lets me control any chat agent in ag from a telegram bot. So that should ideally allow me to replace my human work of checking on agents. It should also allow me to pit claude against gemini and use low models for less smart tasks and costlier models for tasks that require more thinking. I have more or less defined my development workflow in stages where first I write a comprehensive wiki + empty test files with descriptions, then I write the code and then recursively fix the code to meet the test criteria set earlier. I want to automate this with the "controller" thread. I have come to realize a knowledge graph via wiki is the only way I am able to get AI to generate production ready stuff, otherwise its too flaky.

Working on a few things:

Rundash (rundash.ai) - an easy way to create automated AI agents that can run tasks for you with over 1000+ integrations. Built this from my own needs to run better meetings, discover product insights etc..

Provision (provision.ai) - how I run a team of openclaw agents without burning money on Mac minis. Each agent is given a dedicated email inbox (powered by Mailboxkit) and a dedicated chrome browser that you can connect via browser to unblock if needed. Currently doing some pilots with a few startups. It's interesting to learn how teams want to use AI agents like OpenClaw.

[unnamed project] - a macOS menu-bar AI agent that drives your real apps similar to Perplexity Computer. Hit ⌘⌘, type a task (optionally @-mentioning apps like @slack), and an agent Claude Code or Codex; clicks, types, scrolls, switches apps, and reads the screen via accessibility APIs, with a visible cursor so you can watch it work. Everything runs locally on your own logged-in Mac (BYOK to Anthropic/OpenAI), so there’s no cloud VM or re-auth flow. It also snapshots the frontmost app for ambient context ("summarize this page" just works) and supports parallel tasks with persistent history/workspaces. Pre-release, but the core bet is that desktop agents should feel like a teammate living in your menu bar, not a browser tab or rented remote computer.

I go on with my small side-business of modding Skyrim. During lockdown it wasn't clear what Bethesda games the paid mods store will cover; had it been only for new titles, I had only vague idea that Starfield would be some space sci-fi game, so my idea was to make puzzle-adventures using the base game assets (and blending in the world game is nice but optional), and puzzle-adventure is a very broad genre in itself, so maybe I would end up making up distinct unique gameplay for each of the modded games.

Recently I came up with an idea for a puzzle-adventure under Playstation mod limitations. That means no new assets, and no new scripts either. Simply, let's treat it as a different game, and see what can be done with that. I researched the built-in scripts, and oddly, every script that could be used to enable a game object was not repeatable. Ditto for scripts to disable an object. The only repeatable scripts were toggle scripts (disable an object if it is enabled, enable if it is disabled). So last week I prototyped some puzzles using that primitive only, and while doing so, I figured out how to trick the engine into making those do-once scripts repeatable, too...

Old-school graphics in modern TS.

Several years ago, it was not possible to blit an entire screen of random pixels to the screen at a decent frame rate without something like shaders.

Even though the screen is now even higher resolution, the CPU can now blast 2560x1440 random pixels to the screen at 90 FPS. Must be advancements in hardware and/or JS runtime. (The bottleneck seems to be generating the random numbers...)

I figured out how to make my TV static effect look more realistic:

- Mostly: TV "pixels" had wide aspect ratios[1]

- Larger "grains" (see info in corner)

- Also added subtle CRT scan line effect. ('C' to toggle)

- Looks different when animated (click to toggle pause; probably should emulate 60FPS).

---

Started revisiting this rabbit hole while thinking about programming prompts from the new Recurse Center application[2]. They suggest about six different prompts; I figured out how to combine all the prompts together.

I'm working on Prompty.tools (http://prompty.tools), a prompt engineering and management platform where users can search, store and combine building blocks for creating structured AI prompts.

I created the platform because I found myself rewriting the same parts of my prompts (or storing them in a text-file) all the time. Now, with a few simple clicks I can populate all the task-specific fluff (personas, constraints, tones, ...) around the actual task that I want the AI to complete.

The platform is open by default; with the purpose of letting users learn from prompts and building blocks that other users created and use. I don't have any users yet, because I want to complete the MCP and Claude Code Plugin before I start marketing my product.

Other things on the roadmap:

- Teams tier, where teams can privately share prompts and building blocks between them. Currently, your data is either private or public, no targeted sharing.

- LLM integration into the prompt builder to reduce prompt engineering friction even more. Instead of manually searching for, and selecting the building blocks you want to use, you would just start typing your task and let the platform decide what building blocks would best support your prompt. There is still a difference with letting an LLM completely generate the prompt, as we would be using existing building blocks that have real feedback from previous uses.

Let me know what you think!

A small game called Colorhunt to play with my friends https://colorhunt.lol

You get assigned a random colour and have 24 hours to go out and take photos matching it. The game then generates a photo grid from everything you captured.

Modes:

- Solo → 9 photos by yourself - 1v1 → compete against a friend, combined grid at the end - Squad → everyone contributes to a 20-photo grid

No accounts, no app install, no personal data stored. Photos and generated grids auto-delete after 24 hours from Cloudflare R2 storage.

Made it for fun to find a way to do a shared a activity with my girlfriend and also to challenge my friends over the weekends.

Currently redesigning the frontend flow but I am kinda poor at design

dielll2• 2 months ago

Saw a post on Twitter of someone doing it with their spouse and I though lt about creating a web app to help me with colour generation and also grid generation.

The first version was the 1v1 mode and I tried it with a few friends. Later added the squad mode.

A few weeks ago, there was a viral tweet of a colorhunt and in the comments there were several people who said that they would love to participate but they cant because they travel alone, that gave me an idea to create the solo mode. Funny enough it's now the most popular mode in the game.

I do this for fun and also to help me develop my Product Manager skills(would one day love to shift from engineering to product however yet to get an opportunity at my current company). Main reason is just a way to keep InTouch with my friends and just explore colours with them.

I am finally getting close to my vision of `write once run everywhere with SwiftUI`. The idea is to create a drop-in replacement called OmniUI which will have different renderer backends (I currently have TUI w/ notcurses and Adwaita/GTK working)

s/import SwiftUI/import OmniUI/

As long as you aren't using Apple platform specific libraries like Vision, you should be good for the most part. I am going to make my Gopher browser (https://web.navan.dev/iGopherBrowser/) the first target. I have done some extra stuff like reimplementing CoreData/SwiftData to make it work on Linux.

I am going with Adwaita instead of pure GTK because I like the opinionated approach they have with their design language. I think the reason SwiftUI works is because you can get pretty looking apps without thinking too much.

Projects like adwaita-swift, and swift-cross-ui do exist, but I want my library to be a drop-in replacement. I don't want to be inspired by SwiftUI, I want to use SwiftUI everywhere!

But not sure people will be willing to use it. A commitment is highly generic, maybe I need to narrow as daily exercise or something.

Right now working on framing this as an RL problem to better predict when nudging is actually successful and what kind of wording works best given the user data. Then applying the same logic to onboarding emails etc.

Working on https://flakiness.io: GitHub-native test analytics. I worked on Playwright before, and this project started as a natural continuation of that work. We’ve since expanded beyond Playwright to support many popular test runners.

The idea is to connect test results and artifacts with commit history. Test reports should know whether a failure is new, whether a test has been flaky before, and which commit made a test start running 5x slower.

If you maintain an open-source GitHub project with tests, please give it a try. The free plan is a good fit for OSS projects: 1GB of storage is enough for roughly 10M+ test results.

SogaPaper - https://sogapaper.ai/

People are consuming more and more text content than ever before to get more information, under the pressure of AI development. For me, I need to read papers, go through information related to my industry and company, sometimes my boss asks me to conduct a research on some newly launched products or techniques revealed by passages.

It's really a heavy load to consume all these information fast and deep, so I built SogaPaper: https://sogapaper.ai It can translate, summarize, q&a not only at the whole document level, but support paragraph-level quick glances and q&a, preserving the important inner logic and structure of the whole passage, very suitable for knowledge workers and college students nowadays.

It's free to start, and I'm looking forward to hearing from your advices.

A few months ago I got so fed up of squinting at glowing rectangles to stay informed/updated. I feel like there's a finite amount of podcasts I can reasonably follow/digest so I built a very basic prototype to summarise RSS feeds/transform the content and transcribe it in to a personalised podcast.

I put a bit more work in since May have it running almost end to end, still with plenty of gotchas. It's transcribing on an RTX3070 under my desk so pretty limited, but have enjoyed a few morning briefings just as I want them (weather, chance of rain today, BBC/NPR top stories from yesterday, some specific sports news then HN most popular summarised with summary of comments. Got a chuckle out of the LLM summarisation of HN commen threads which was always "Comments reaction: mixed" (which it no longer embeds!)

Found traces of it being done before and I understand you can do similar in Notebook LM, but I was hoping to build something set-and-forget.

I'm working on [Context Bonsai][1] - LLM harness tools that allow the LLM to prune messages out of the context, leaving behind a summary and keywords instead. In addition to a "prune" tool, there is a "retrieve" tool that allows it to recall the messages if needed.

In addition to these tools, I'm also building automation that will port the tools from the reference implementation (OpenCode) to other harnesses (Claude Code, Cline, Pi, Gemini, Kilo, Codex, others to come?). As well as automation that will either cherry-pick or re-implement commits onto the latest head from upstream.

Yes, also happening more or less continually instead of waiting for the context to bloat up.

European night trains search engine. The plan is not to provide the functionality where user searches for a specific route on a specific date and the engine returns prices. The plan is to provide "tips for trips", e.g. I provide a starting city and it will recommend me interesting trip ideas any time in the future. There are many flight apps that provide this functionality, but no train app.

Currently I'm building scrapers for all relevant provider, then I want to connect the data for multi-city trips recommendation. Plus some connection to the day trains so that the trips are built more easily.

Some existing trip recommendations:

Prague <-> Amsterdam https://trainbot.eu/?from=prague&to=amsterdam&type=return

Berlin <-> Paris https://trainbot.eu/?from=berlin&to=paris&type=return

Zurich <-> Budapest https://trainbot.eu/?from=zurich&to=budapest&type=return

530 eur for return train from Prague to Frankfurt? I guess the reason why there aren't any train apps is that traveling by train seems useless at these prices... :(

druskacik10• 2 months ago

That's the Prague - Zurich NightJet that's hellishly expensive, possibly because the target audience are Swiss people for whom it's not so much :D Also, NightJet does not price very dynamically as opposed to other providers, and their baseline price is always quite high.

But yes, in most cases this journey will be more expensive that an alternative flight, which is a shame. However, there are routes where it's comparable, e.g. the Prague - Amsterdam route.

medvidek• 2 months ago

For some reason Prague -> Bratislava trips are only shown with departures at 00:36 even though there are several through cars that leave Prague at 21:58 (and join the rest of the listed NightJet in Breclav), which is much more comfortable for your average traveler. Ceske drahy website has both connections, so maybe you aren't scraping it yet?

druskacik10• 2 months ago

Hm, thanks for the tip, I didn't know that. I scrape NightJet website, which lists only the 00:36 train. I'll look into it.

outside1234• 2 months ago

Thank you for building this! I might be holding it wrong, but I would like to be able to search for all night trains from a particular origin. Is that possible?

druskacik10• 2 months ago

Currently not possible, but:

- once you fill the "From" field with your start city, the "To" field will include only cities reachable from the "From" city

- at https://trainbot.eu/coverage/ you can search for all routes that go through your city

I plan to add a subpage for every relevant city with recommended routes once I'll have enough data. Something like https://www.seat61.com/ but with actual prices and dates.

jll293• 2 months ago

Now you if you wanted to visit the best city in the world (Edinburgh), you could of course take the Caledonian Sleeper night train from London up to the Scottish capital; but then you would completely miss out on the beautiful views of the country and the sea.

This case perhaps merits a hard-wired message "for this trip, we recommend a day train, or we'd regret you'd miss the panoramic views".

mb2100• 2 months ago

Sounds similar to https://nightride.com ?

druskacik10• 2 months ago

It's definitely similar, but the philosophy seems different. NightRide supports exactly the use case on searching a route on a specific date. I also noticed that if they don't have the price pre-scraped, a scrape is called dynamically on user's request.

My idea is to pre-scrape the prices and answer questions such as: wanna go to Amsterdam for a weekend? -> here are the best dates and prices.

An alternative to Ansible and Puppet, written in Golang.

It's called Peekl, and the idea behind it was to merge the two things I loved about both Ansible, and Puppet : - The agent/server model of Puppet; - The ease of writing Ansible code.

It also make sure to solve the problem that both Ansible and Puppet have in my sense : - Puppet is a slow, decades old application. It's written in Ruby and run inside of a JVM for the server. Applying a catalog can be very long on complex configuration setup. - Ansible on the other side works well, but the absence of an agent makes it hard to deploy stuff at scale : You being spending more time running your playbooks, than actually doing stuff.

So if you want to take a look at this alternative, head to the Github repository. Feel free to break it, open issues, and pull requests !

https://github.com/peeklapp/peekl

brianjlogan18• 2 months ago

I like your idea. I didn't have the time to fully build mine out but I also was hankering for something with better readability and implementation than SaltStack (server/client similar to Puppet).

https://github.com/vangourd/g8r

The pub/sub model was so much FASTER than the Ansible push methodology.

I'll check your repo out for sure

redat002• 2 months ago

Yes the pub/sub model gets way faster than the Ansible push model, especially at scale : When you start having a few hundreds of servers, you'll see that you just spend so much time waiting for the playbook to run.

It's also heavily bound to network connectivity, if your server your reaching has 100ms of latency, every time Ansible does something, you will feel those 100ms.

In the case of Peekl, it's easy : The server will read the content from the local disk (depending on what roles you have, your groups, and also load the variables.) And simply sends the "compiled catalog" to your agent who will go through all of it and performs actions as needed.

Since last summer, I am working on a yet another Wine prefix manager, called Wine Bar [1]. My main motivation was to have a user-friendly and opensource tool that can run (some) Windows apps on my Macbook Air M2 running Linux. Before you ask, it supports regular x86_64 Linux as well.

Besides, I wasn't entirely happy with the existing Wine launchers, namely Lutris / Heroic / Bottles (none of which support Linux on Apple hardware, although I was able to run an old version of Heroic under muvm).

I wanted more control. For instance, sometimes I need to install a Windows component using winetricks before an installer for some Windows app would agree to run. I also wanted even more user-friendliness. I didn't want to manually specify the executable in the installation folder to run. I wanted the executable to automatically appear on a "Desktop" in the UI as a result of running the installer for a Windows app. All of that I've achieved.

Recently, I've put a very significant effort to make a Snap version of Wine Bar. An x86_64 Snap wouldn't be terribly difficult to make, but packaging an arm64 version as a Snap and making it work was really-really hard. That's because Linux on Apple hardware uses a non-4K hardware page size. So, running Windows apps in such an environment involves running a full-blown 4K-page Linux kernel inside a micro-VM. From within the VM, you register FEX-EMU as a binfmt-misc handler, and then finally you are able to run a Wine process or a wrapper around it (like Proton). Oh, in order for that to work, you also need to provide an x86_64 / x86 RootFS image for FEX-EMU. All those components need to be built as part of the Snap build process.

Long story short, I succeeded and the Snap version of Wine Bar is available from the Snap Store, yet I am still waiting [2] (for over 2 weeks without any reaction) for a couple of permissions to be granted to it. That's not a showstopper though, as the permissions may be granted manually by the user.

Way to stay connected with a family abroad.

I migrated to another country and it's hard to talk with parents, my sister and grandmas as much as I did when I was back home. We tried making weekly calls to talk and play games but someone could never make it. I got an idea to create a small chat, share a simple topic every morning and then let everyone take a picture of the object. For example, recently we had "Garden" which made my grandma in the countryside go outside and take a picture of her growing strawberries. Today is "Anything halal" and I hope this will make another (Muslim) grandma in the chat happier :-)

At first, all topics were made up by me. Then, I made it possible for others to suggest topics via a simple bot. I showed this chat to friends and they got excited and wanted to try the same so I upgraded the bot to support multiple chats.

I recently released my first Steam game, a little physics soccer game about scoring great goals: https://store.steampowered.com/app/3802120/Put_One_In_for_Jo.... It's not successful, but I'm very happy with how it came out, and I learned a lot.

I've been using and tuning a tool I built myself to help me lower my LDL and ApoB: https://www.heartroutine.com/. I still don't like how the daily check-in system works (it's still too dumb) but it's keeping me consistent for now.

In a few days I'll start running playtests of my combat prototype for my next game, Today I Will Destroy You, some kind of SNES Zelda and Sekiro inspired combat adventure.

Periodically thinking about what the future of helping small teams build software will look like and keeping my personal site up to date: https://piinecone.com/.

I am currently building a powerful TUI database client (that supports Turso as well) as I grew fed up with heavy db clients that take gigabytes of ram when rendering data that is text. It's also very convenient since you can launch it with a saved connection from any terminal anywhere.

It's still early in 0.1v at https://github.com/okira-e/TUIQL but already supports everything day-to-day that you would need.

Started some playtests for our game with my brother (I mean we don't REALLY have testers yet, we need a bit more work first because right now it's lacking 1 or 2 core elements of the fun / gameplay loop): https://srdnvntrz.itch.io/runz

also created and got our steam page validated: https://store.steampowered.com/app/4704420/runz/

We've been moving fast, it's our second project and we hope to deliver something people find fun and appealing, at least for our friends !

We suck at marketing though (such is the game dev burden), but we're having fun and learning stuff, which is what it's all about I guess.

So i just finished a long running project (10 years ftw) just to deepdive into the next one.

I have no public sources yet (will come at some point) but ill try to break it down into some simple points. After all: this is a research project.

Project: DeepThought

So instead of going for the path to take bigger and bigger models to solve more complex questions, i going another direction. My idea is to use LLM's in a way like an "inner monologue" to replicate a thought chain. Basically create thinking steps that can be dynamically chained.

Additionally, the project contains a 3 layer memory system which is parted into:

1. Frontbrain (this data composes the context for inference, its a set of "hot nodes" which have a temprature that per turn of conversation will cool down a bit, while if they are used in a "thinking process" get warmed up a big again. The idea is to have the context for the inference to only get the currently relevant information, while dropping of things that lost relevance. This should prevent context overflow

2. STM : Basically a session memory. This will keep all information from the current session even if they got to cold and dropped out of Frontbrain

3. LTS : LTS is always query'able for the thought process to retrieve information/structures, but only at the sessions end information is propagated from the STM to LTS. This makes identification of "unique" entities alot easier and has some other advantages.

So when you type something into the DeepThought engine, it will extract all information from your input and convert it into a kinda 2 type structure 1. A bitemporal hypergraph composed of Entities and Hyperatoms. While entities i think are kinda easy to grasp, hyperatoms can either represent "properties" (in form of facts) or relations to other entities. This allows to create a graph structure typed information network containing the relevant information

2. Frame summaries. Since only having a structured graph as just described looses a lot of processual/logical information which are relevant especially in more complex contexts, i also create basically short summary texts that are linked to entities.

This structures allow me to use dynamic graph traversal for searching for data, while also retrieving the related Frame summaries that are a more native variant for an LLM to understand logics and relations.

This is a very very superifical explaination because to go into detail would take quite prolly multiplage pages of info.

Important: Im running this on a local 5090 and it is NOT friendly in terms of amount of inferences (which is fine for me). I try to mimic a thought process not build a fast shipping product. Quality > quantity. If you would run DeepThought on any online inference provider your broke in 1 day.

So, rn i focus on the ingestion and retrieval logics to make storing and retrieving as good as possible with my hw options.

While the ingestions already involves multiple steps in which the "llm" basically works as judge to decide where to traverse in the graph, where to go into recursion and similar, this will become very relevant as soon ill start implementing "task execution" as capability.

If i solved those the next point is to reduce everything that i need in terms of thinking steps in what i would call "thinking primitives". The idea with those is, that i dont want a hardcoded thinking process, but it rather also want to have the thinking process in form of a graph structure. This would allow me to compose the process in form of data in the hyepergraph, which would in return allow me to enable the system to refactor/enhance its own thought processes.

So ye thats what im working on rn, very early concept/alpha phase.

I am working on a minimalist journal app that is for really quick single line jots. Can be used for idea dumping, project management, quick calculations, unit conversion, task management etc. Have unlimited undo/redo support, assign tags etc. Will be adding scripting support using Python next. The data is stored in text file, in really human friendly manner, but also in way so that the *nix tool users can easy to navigate the file using text processing tools.

Native application, no web UI, built using Rust + iced.rs, minimal dependency. NO AI.

I am putting the best effort to make it performant. Target audience is the users who want's the simplicity of the notepad [non-sloppy one], but still with some bells and whistles to note without worrying about managing the metadata manually.

I think with scripting there will be infinite possibilities to play with linear notes, and I want to make that happen.

Continuous challenges while implementing features are:

  1. It should load instantly
  2. Keeping it extremely simple to use
  3. Keeping the interface minimal
  4. Still have ways to let the user find the features easily.

Will have a demo version ready soon

Building a personal internet archive and knowledge management stack. It's in a rough state but I'm using it every day.

Cham (https://github.com/jfim/cham) is an archive for internet content, you give it an URL and it'll archive it for you, extract the text with readability if it's an article, or extract the audio track then transcribe it. Content is automatically summarized and tagged, and you can start a conversation with a LLM about the article. It supports feeds too so you can subscribe to blogs and keep the articles in case the blog goes away. I still need to add search, improve the CLI, add all the missing features, and do a lot of improvements all over the place.

To improve reliability, I made passe-partout which is basically a Chrome browser with a rest API (https://github.com/jfim/passe-partout) and veilleur (https://github.com/jfim/veilleur) which turns any blog listing into a RSS feed. So this way I can take blogs that are rendered using JavaScript, don't have a RSS feed and load the articles directly into Cham.

Also built a modular MCP server with OAuth2 dynamic registration so that I can have my own MCP server that works with the web, desktop, and cli versions of Claude/Claude code. Currently have modules for editing files so that I can edit/search my Obsidian vault from Claude, fetching pages through passe-partout (since some pages block LLMs from reading them), and proxying MCP servers so that servers that only support bearer token auth can still work with web Claude.

Also, a gnome terminal emulator UI with some unique features like split browser/terminal tabs. https://github.com/jfim/jfterm

Mostly an excuse to see how far I can push LLM code generation to write tons of software that I've always wanted but never had the bandwidth to tackle, and learning to deal with the sometimes questionable code quality that comes from it.

I'm building yet another terminal [1][2] for macOS and Linux. I've been unsatisfied with the window management of iterm2 and other terminals, my one acts a bit more like Chrome with projects at the top level.

It also allows remote control. I don't like AI harnesses (Claude / OpenAI) having remote control inside, it feels like it should be at the terminal level, not the cli.

It also allows commands at the terminal level. So if you use multiple ai cli's you don't only need to write the command once, then use cmd+l to inject into any cli.

I've put macros in too, that again can automate doing the same thing in a terminal.

Anyway I'm sure this will just end up another terminal in a sea of already existing ones.

DAGraph is a local-first reactive DAG for analytical SQL (OLAP), running entirely in the browser (there is also a native version in the works).

Some tech details: written in Rust, targeting WASM (and native). The SQL engine is Apache DataFusion[1]. The UI uses Egui[2]. Workspace data is persisted in browser using OPFS[3] via OpenDAL[4]. The graph is functional and handles dependencies for you (via parsing the SQL).

Building this to be accessible for beginners while remaining powerful for advanced users. Still very early, lots more features to add, but now usable.

Building a GNSS/RTK-based lawnmower.

The existing ones were quite expensive, especially when I started out. A friend had the idea to get a cheap/non-functioning lawnmower second hand, and tear out the circuit board. We're in the process of coding up a new ROS2 based stack that will roam the lawn on GPS with RTK in the charging station. My friend does most of the electronics stuff, and I focus on the software.

I'm at the point where I will start testing a simple bounding box soon and just have it drive around until it "hits the edge" and then randomly pick a new direction.

It's fun so see the software I build "in real life" instead of as a web-site, as is the case for my my daily job.

Having some progress on CircuitScript, a python like language for describing electronic schematics as code: https://circuitscript.net. Try the language through the online IDE at https://bench.circuitscript.net

In the past 2 months, I have added support for exporting to the .kicad_sch format. Multi-sheet designs are exported as separate .kicad_sch files, one per sheet. The pin types has been updated to be similar to KiCad's and to better support ERC rules. Setting the GND symbol pin as a type of power_input was a real headache for me, eventually, I decided to define a new pin type, power_reference.

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

Feedback welcome, especially from anyone else frustrated with graphical schematic tools!

Currently working on Bedevere Wise (https://bedeverewise.app), a browser-based SQL data viewer for the file formats still widely used by biostat / clinical-data people: SAS (sas7bdat, xpt), SPSS (sav), Stata (dta), plus Parquet, Excel, and CSV. Everything runs locally: DuckDB-WASM (the SQL engine), the file parser, statistical and plot library (a DuckDB extension that I built).

I wanted a "drop file → SELECT * FROM it" and run a few other explorative queries on a dataset (provided in one of the formats mentioned above). Sometimes, it might even be a whole nested subtree with dozens of files that includes all or most of the formats I mentioned above (trust me, I've seen it many times). I also wanted something easy to use for my colleagues: no installers, no configurations, no faff. And, most importantly, files never leave the device (which matters for clinical data).

The plotting half is GGSQL. I read Thomas Lin Pedersen / Posit's alpha release a couple of weeks ago (https://news.ycombinator.com/item?id=47833558) and that's when I realised I could add the "Grammar of Graphics inside SQL" into Bedevere. So pasting

VISUALIZE bill_depth_mm AS x , bill_length_mm AS y , species AS color FROM penguins_clean DRAW point ;

in the editor pops a chart without anything leaving the device.

This is the demo for the impatient (I admit I am usually one): https://bedeverewise.app/demo (The query is ready to be run in the editor).

Feedback is very welcome.

I've been working on DeskTalk(https://www.desktalk.ai/), an AI-native desktop environment that runs in the browser.

The idea is pretty simple: I want an OS where people can just describe the app they want, have AI build it on the spot, keep tweaking it in real time, and also use AI to operate the whole thing. Not just chat with an assistant sitting off to the side, but actually let the assistant create apps, edit them in place, manage windows, and help you get work done.

So instead of installing a bunch of software up front, you can say “build me a tracker” or “make this app simpler” and the system just does it. If something feels off, you tell it what to change and it updates live.

Still early, but that’s the direction I’m excited about: software that feels less fixed and more malleable.

I had an idea about explaining ML predictions without direct access to the data or the model: provide basic stats about your data, use them to generate synthetic data, then train a surrogate to predict your model's predictions on the synthetic data.

Could be handy for model risk management and governance, e.g. if you need a challenger model for SR 11-7 without all the hassle of getting access to the original data, getting the black box model set up, and so on. I wrote it because I remember having to create "throwaway" models to show why I needed a better model; it would have been nice to just make a couple of API calls instead.

So I had an idea for a music app that tries to minimize the amount of music theory needed to play as a group.

Basically you pick a key, then it's just 7 buttons that play the notes in that key. Actually 21 because there are three octaves.

This has some neat effects. You can play thirds by just hitting every other button.

I wanted kids to get started playing as a group without having to worry about wrong notes. Everything is in the same key so it never sounds too bad.

There's not much to look at, I just started it last Friday. https://github.com/wmill/EasyMusic

I'm working on Coderbase (https://coderba.se/), a platform for running technical interviews. It started with live interviews cuz that's what I know best, having run over 3,000 interviews in my career, but I made it easy af to run this yourself too. I initially pictured it as a tech-heavy product (and it is), but my second client is a large recruitment agency that's using it both for internal interviews (for recruiters) and external ones (for candidates they're presenting to clients).

I didn't set out to do this. After I got laid off in December, a client quickly fell in my lap: a small startup in the middle of a massive investment round that needed to hire 25 people immediately, with only a CTO available for interviews. I created their content and ran their interviews while building the software at the same time. It started as Google Meet + CoderPad + Calendly and gradually became an in-house system. Unlike Proton (lol), I'm not pretending I built my own video call solution from scratch, it's just an off-the-shelf 100ms integration.

The content is all versioned and structured, which makes it fast to iterate on and easy to reason about. We use major.minor versions and only bump the major for backwards-incompatible changes, or changes big enough that comparing interviews stops making sense. Otherwise, any combination of question versions inside an interview format is considered comparable if the major versions are identical.

The interview itself is highly structured: once you define a format from the content library and the various knobs you can adjust, you can schedule interviews and run them using our integrated "room" (video call + multiplayer code editor, both recorded, with transcripts and playback) and "rubric" (the tool the interviewer uses for content, scoring, and notes during the interview). Once you submit/publish the interview, a report is generated immediately. Example: https://coderba.se/sample

Two interesting AI bits:

- "AI linting": a way to benchmark interview questions by running a candidate model and an interviewer model against each other. The candidate closely follows a defined skills profile, then we compare actual vs expected performance. More here: https://coderba.se/blog/product-update-unit-testing-the-inte...

- "AI draft": once an interview ends, it takes ~30s for the video and transcript to become available. Then we use basically every relevant artifact from the interview, with a PII redaction pass first: questions, scoring, incomplete rubric, transcript, code editor history. We send that through our LLM gateway, currently mostly using DeepSeek because the quality/value is insane, though I may switch to Mistral to stay on the better side of privacy. It sends back recommended scoring + writeup, which we present as Cursor-like suggestions you can accept/reject/edit.

Currently supports docker, containerd, wasm runtimes. I am adding support for jvm and kvm, etc. Works as is in macos. There is mock runtime too to mock it for various testing various distributed services etc.

It is a fun little experimental project.

I built a maintenance tracking app that I can use for household/garden tasks. I had a problem where things like replacing a battery for a chicken coop, I'd be a month late on replacing it and I had it in my calendar to replace every august, so I'd be replacing it early every year. And I also had in my calendar to fertilize my hop plants every 2 weeks, which meant in January I'd get a calendar event to fertilize my hop plants.

And sometimes my wife wonders what we have to do (especially in spring) for gardening, planting, chickens, etc.

I have paid for to do apps to try and tackle this by using the NLP "every 3 months" etc to basically accomplish this.

I think you're smart to spin it out to its own thing because I tend to use them differently batching my chores into a time gate and then using my "chore list" to know what needs to be done. And also the notifications for chores tend to distract from "Important one time task you don't want to forget".

I'd consider paying for this if the app was well done and reasonably priced.

I'm working on Maelstrom, an agent framework with only the basics:

- 'agent' as cognitive state, ie, what to think about

- 'workflow' as 'what to think about

- 'session' as immutable agent history

- 'timers' as a way to kick off an agent on a schedule (with or without a workflow attached

I've been working on this since just before OpenClaw dropped at the end of January. Currently it weighs in at around 20k lines of code. There is still a significant amount of work to be done on polish, but the core appears to be functional, and almost to the point where I can replace opencode as my daily driver (I'm very much looking forward to this).

From [1]:

---

I've been working on a framework since the end of January or so. I'm on my 7th draft. As I've gone along, each draft gets markedly smaller. The overlaps between what I'm building and openclaw are significant, but I've realized the elements that make up the system are distinct, small, and modular (by design). There are only a few primitives:

1. session history

1a. context map + rendered context map (think of a drive partitioning scheme, but for context -- you can specify what goes into each block of context and this gets built before being sent out for inference).

2. agent definition / runtime

3. workflow definition / runtime

4. workflow history

5. runtime history (for all the stuff session and workflow history fail to capture because they are at a lower level in the stack)

That's it. Everything else builds on top of these primitives, including

- memory (a new context block that you add to a context map)

- tool usage (which is a set of hooks on inference return and can optionally send the output straight back for inference -- this is a special case inside the inference loop and so just lives there)

- anything to do with agent operating environment (this is an extension of workflows)

- anything to do with governance/provenance/security (this is an extension of either workflows and/or agent operating environment... I haven't nailed this down yet).

I suppose I should say something about how agents and workflows work together. I've broken up 'what to do' and 'how to think' into the two primitives of 'workflow' and 'agent' respectively. An agent's context map will have a section for system prompt and cognitive prompt, and an agent can 'bind' to a workflow. When bound, the agent has an additional field in their context map that spells out the workflow state the agent is in, the available tools, and state exit criteria. Ideally an agent can bind/unbind from a workflow at will, which means long-running workflows are durable beyond just agent activity. There's some nuance here in how session history from a workflow is stored, and I haven't figured that out yet.

Generally, the idea of a workflow allows you to do things like scheduled tasks, user UI, connectors to a variety of comms interfaces, tasks requiring specific outputs, etc. The primitive lays the foundation for a huge chunk of functionality that openclaw and others expose.

It's been fun reasoning through this, and I'll admit that I've had an awful lot of FOMO in the mean time, as I watch so many other harnesses come online. The majority of them look polished, and are well marketed (as far as AI hype marketing goes). But I've managed to stay the course so far.

I hope you find your ideal fit. These tools have the potential to be very powerful if we can manage to build them well enough.

Alright, I am building QuizFox, a small daily trivia app for iOS: https://apps.apple.com/us/app/quizfox-daily-trivia-game/id67...

I’ve always liked trivia / Jeopardy-style games and learning, so this started as a fun side project to see how quickly I could build and ship something “real” using AI-assisted development (I got my niece and nephews in there trying it out, so a success there for them to see that they can build the next new awesome app themselves!).

AI dev is definitely hit or miss on development, but I am surprised at how well AI is doing some app dev tasks (using frameworks it does exceedingly well, not surprising!), and also some misses (trivia writing it does oddly well, but verifiability is imperfect, I had some issues early on with hallucination to fix, but pretty good now!).

Would love feedback, especially on the onboarding, obvious gotchas, question quality, and the app overall, I am using it to learn a lot quickly!

[Vaava](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/ , which originally was also purely for my own use. Most sports and fitness wearable manufacturers own software and 3rd party software make it incredibly hard to do "how does my this months metric x compare to same month last year", athilio attempts to make those queries easier. Many of the ideas are basically copied from software observability concepts. Also I have used the app to implement and learn agentic workflows.

I'm making a joke-website, "Everyone Loses as a Service (ELaaS)" [1]

The premise is essentially:

1) Accept money from angry customers asking us to prompt-hole tokens from targetedCompany chatbots

2) Approach targetedCompanies to offer the "real" (secret) service. For a monthly subscription fee, we won't prompt-hole their LLM tooling.

3) The real, real service is to setup some google alerts for targetedCompany release notes & forum posts. Whenever threshold exceeds some predetermined threshold, initiate Turbo Mode: the higher the hatred-per-customer, the greater the discount the service will be for them. Spit out newsletters as needed, regardless of whether or not they subscribed.

Meanwhile, initiate "surge pricing" for targetedCompany on a per-hour, per-payment basis. The more customers that pay, the higher the "one-time fee" is to targetedCompany.

Staffing is almost entirely made up of interns, a few roles are filled by underpaid contractors with unattainable goals; keep them both working there with the promise of full time employment "after things calm down."

If all goes well, everyone pays us money to do absolutely nothing with minimal outflow of revenue.

Oh! I have so many in-progress projects right now,

First up, the "AskHN for help project in progress": I'm working on some pages for my websites and want to capture + embed some interactive gaussian splats. I haven't yet found a good, embedded-able option that doesn't assume a huge dynamic website instead of my simple Hugo based static site. Any good options?

Otherwise,

I just got a vintage horn-speaker. The actual Atwater Kent driver was long since dead, but I ordered a compression driver to feed it after testing it with a talkbox and finding it sounds amazingly honky!

I have a piano's soundboard and 24 solenoids, all the drivers, etc I need to wire up to make a self playing piano (ish, I mean, it won't be hitting hammers - directly solenoid to string)

I got tired of Alexa's slow degradation into a central advertising point and weird LLM-y-ness, so just got some Home Assistant Voice Preview Editions to replace it. Performance is so far worse, so I'll be doing some tuning on that. It also means, unfortunately, replacing a lot of my lights/switches and moving to Zigbee. Total cost, with the two voice/speaker boxes + lights + switches + Zigbee hub I think I'll be about $300 deep. Not too bad.

I have a Dactyl Manuform mechanical keyboard that's 3D printed, has the keys put in, but needs soldered up, hopefully able to knock that out soon too.

Old eleksmaker pen plotter / laser engraver sitting around had it's controller die a while ago, finally got a new one, but will have to actually learn how to setup GRBL and find some open source software for driving - Which, sounds less than fun. Last time I tried, I found all the software to be expensive, hard to use, and generally frustrating.

On top of all of that,

* I have a Hurdy Gurdy sitting at about 3/4 finished, shouldn't need more than another 8 or so hours of work to get playable.

* I want to make some Nuclear Instrumentation Module inspired modules for VCV rack

* I have an AudioMoth on the way, I'm looking forward to learning how to setup so I can learn about bats in my area!

* I'm still about 75% done switching back to linux, now that I feel it's finally ready to be used for music stuff since the transition to Pipewire seems over with and It's no longer a total mess of ALSA+JACK+Pulse+PipeWire. That transition hell mad me switch back to windows for few years, and it's nice to be back

Also, since the last thread I've managed to fully rebuild my studio setup, setting up multiple 3-tier stands for synths + the Wall-o-pedals. It came out really well! Was nice to brush up on at least basic wood working skills for it too. During that project I also discovered 3M dual lock is magic and will be over-using it on everything from now on.

Linux distribution experiment where all user data (/home) is loaded from a model

Distro boots to a custom Vulkan based, GPU accelerated browser; like a game engine or blender where the controls/parameters are hidden and updates are driven by AI given a prompt

Am using BPF and sched_ext to manage a bunch of the usual behind the scenes telemetry and observability and inform the AI which responds by tweaking run state

So / and /root and /usr, the other POSIX paths exist but instead of /home it's an encoded binary model.

No unique users relative to the OS, but while I run everything as root the AI protects the model unless given the appropriate secret.

Not perfect security by any means but this is an experiment above all not a production system

More than often you ask the AI to do something. It misunderstands. You correct it by words. But the messed-up turn stays in context, and the AI is fighting both your correction and its own past mistake.

retcon flips the model. The tool is named for the verb recontextualize: introducing new information that reshapes how the past is understood. Instead of you typing a /rewind command, the AI retcons its own past. You just tell it what you want.

I have been quietly working for the last three years: a novel hierarchical and extensible modeling framework that can cleanly and efficiently embed any json-like object for any predictive modeling task with zero feature engineering.

json2vec enables users to, for example, build tabular / transactional foundation models like TabBERT / PRAGMA dynamically... by just declaring their data schema. This is a space in which Netflix, Stripe, Revolut, Capital One, Nubank, J.P. Morgan, NVIDIA, etc. have been developing for several years.

json2vec goes a step further from just tabular data or structured transactional data. It enables arbitrary structured "json-like" observations with hierarchical BERT-like transformer encoder blocks. Financial transactions, chess positions, flight itineraries, raw tabular data, rideshare activity, ecommerce, behavioral sequence models... Any raw data able to be represented in `json` can be encoded into a tree of embeddings, and used for downstream finetuning for supervised machine learning... No feature engineering required.

https://github.com/granthamtaylor/json2vec

json2vec supports extensible plugin support for new data types (numbers, categories, raw text, datetimes, hashable objects [think: IP addresses and phone numbers], and raw embeddings), all of which may be pretrained via MLM-like self-supervised learning. If your needs are not met with the built-in datatypes, the framework is extensible in that you may build your own custom datatypes (think: geographical coordinates). Built in decision heads for a subset of datatypes enable predictive modeling multi-task and multi-array outputs (predicting fraud at a per-transaction level, or a per-account level).

json2vec also enables built in data pipelines for 100b+ training observations streaming from cloud storage. These pipelines integrate with layer of programmatic data querying and UDFs can consume the vast majority of upstream data processing so that developers don't waste time on massive batch data preprocessing jobs before model training.

Oh, and the best part: the model architectures instantiated by json2vec are mutable. Model developers can add and remove features and targets at their whim - allowing for truly reusable foundation models that can adapt for each individual use case.

My hope is that with a standardized hierarchical modeling framework, interested organizations can better collaborate with one by sharing reusable logic with one another instead of hardcoding use-case-specific architecture.

I’m working on https://assistedlist.com

From personal experience finding and researching senior care ends up being a big trap, they lead you into a sales funnel before you can clearly compare real options. Data is hidden behind walls and when your under time pressure, and trying to make a serious decision, you end up hitting a search experience that is dominated by SEO pages, phone-number capture, referral incentives, all because your contact info is the product they will sell to elder care facilities.

Focused on Florida first to get the right UX and details needed.

My goal is is to make it way simpler with real prices and data research first and then add AI advisors who can make it much easier to make an informed decision. Then adding products that cut out the middle man, because it feels broken and shady right now.

The idea is to guide spending before it happens, not just track transactions afterward.

I regularly use about half a dozen programs that interface with radio equipment. Most of it works but getting it all working together is extremely complex.

Since primarily interested in FT8 and MeshCore here in the local SoCal MC region (wcmesh.com) I put together a Pure-Golang implementation to combine both modes into the same GUI client. The FT8 modem might be the only functional Golang decoder right now, unsure, but it’s entirely open source and here:

https://github.com/kyleomalley/nocordhf

The workflow releases cross compiled for MacOS (notarized), Windows, Linux and uses Fyne for the UI.

In the future, I plan to add other more interesting modes like JS8Call and VeraHF modes, FT4 etc.

In my effort to better understand Deeplearning I built this project (https://github.com/sateeshkumarb/anomaly_detection) to detect anomalies from a batch of loglines. I use 1D CNN and Siamese network (Triplet loss) to train the model to learn anomaly patterns from logs. The goal was to detect anomalies that emerge across multiple lines (e.g., error bursts) rather than just single-line keywords.

To validate the approach I trained the model on generating synthetic data. I did look at datasets available at: https://github.com/logpai/loghub, https://www.unb.ca/cic/datasets/index.html but couldn't find one that would suit my needs.

The approach seems to work on synthetic dataset (with ROC AUC score: 0.9957) but couldn't try it out in a real world dataset. Seeking feedback on the approach.

Lately I've been building Aho (https://aho.com) -- an API for verifying age, credentials, and identity using cryptographic proof from digital wallets instead of document inspection.

For context, I built out Playboy's age verification system, and watched as it hurt conversion (nobody wants to upload an ID to an adult website, who would have thought!). Cryptographic signatures from issuing authorities (DMVs, universities, employers, etc) with selective disclosure (e.g. you don't need to upload your full ID, just the fields that matter) is how verification _has_ to work going forward -- AI can fake documents, but not private keys.

I've been working on this 6 months full time, and implemented all the W3C VC, OpenID4VCI/VP, SD-JWT specifications myself.

Would love to get people's thoughts on it!

I’ve been tinkering with an LLM-based assistant for small-scale web development team's knowledge base.

Picking a tool and setting up a knowledge base to have technical and design decisions, notes, and maintenance logs in a single place is usually straightforward. It's the consistently feeding the system with high-quality data part that we get stuck at.

Eventually, I have to input information when I lack the necessary mental bandwidth, I end up creating incomplete entries that lack essential details.

The initial idea is to develop a chat interface that allows us to share random pieces of information, either through text or voice, and have it scanned for actionable data that can be ingested. Then it should start probing the user, looking to expand and refine the new information, connecting it with existing data, and general maintenance of the repository. All with no active guidance.

For instance, I could launch it and say: “Today the team and I discussed how frequently the databases for project A and B should be synced. We established the user can tolerate up to 10 minutes of tardiness", at which point I would expect it to:

- Create a note of this discussion happening - Check and fix the existence of entries for projects A and B - Link the note to the projects - Create database entries for both projects - Look for previous entries that could be linked to the projects - Ask for further explanation of how we came to that conclusion

Cursor for AI PMs/Forward Deployed PMs.

A lot of engineers are trying to build the “Cursor for PMs.” As an engineer-turned-PM with several YOE in both roles, I appreciate their intent, but most are not solving the elephant in the room for the next generation of PMs, so I decided to step in.

Engineers wrote code. Designers produced design artifacts. Product Managers HAD to write PRDs as a way of communicating intent to gain alignment across teams; it was never their only job (would’ve been easy if it was!). The PRD was the means to the end, not the end itself, which is where most engineers are stuck building another AI-native text editor to become the next Cursor for PMs.

Today’s AI tools can generate PRDs, fancy roadmaps, complex spreadsheets, beautiful decks, and no-context OKRs, but the real job of PMs was always quick alignment, principled decision-making, and leadership buy-in with little to no data, something no AI tools can reliably solve today. We now have a unique opportunity to (potentially) solve these big, hairy problems with AI. I’m starting with orchestrating humans and agents to make better decisions.

Loving it so far. AI tools make me wish there were more hours in a day!

We started this because we were building https://www.parsnip.ai/, an app to help people learn how to cook.

We ended up generalizing the platform to education in other domains (K-12, higher ed, workforce) as B2B2B "AI learning infrastructure" but still have our cooking app which is also starting to take advantage of this R&D finally coming to fruition!

I'm working on two projects:

- TTZ: A sort of next-gen protocol for terminals. The basic idea is to create a dedicated terminal protocol that allows for more features and less legacy cruft (text and commands are cleanly separated). Right now, I’ve defined the protocol and have a couple of implementations ready. It already supports pictures, vector graphics, and file and audio streaming. I love terminals and TUIs, but I found programming and developing UIs against the standard terminal protocols frustrating, so I tried to design a more "modern" version.

- KingD (temp name): A Linux-based OS that tries to unify the roles of router, NAS, and virtualization platform with a single user interface. In my day job, I need to manage multiple FreeNAS, OPNsense, and Proxmox installations, and I wanted something that "encoded" the common workflows I keep repeating and provided a single centralized platform. I’ve been working on this for a while, and I hope to be able to do a Show HN by the end of the summer.

Auto-fallback based on extracted character count. - Smart templates use vector similarity (Qdrant) to classify docs, then LLM extraction for fields — no regex, so layout drift doesn't break templates. - Local Ollama or Azure OpenAI, switchable per-user.

Last week, I got it all the way to launch and then had reports of login problems. It turns out that Spotify changed its developer terms last year and I can't accept public users unless I'm in their partner program. That has a requirement of 250k MAU. So, everyone was declined when the tried to login. I'm limited to just 5 users. That sucks, but I invited 5 friends to use it and we just bang out epic playlists.

Currently my biggest project is an MCP that's going to be able to clone other apps in the app store. I know what it sounds like: it's not a very good look. At the end of the day you can use cloud design and ChatGPT image but the better these AIs get at UI, the higher the standard is going to be for UI. Meaning if cloud design and ChatGPT get amazing at UI, or Codex gets amazing at UI, that is going to be the new standard of AI slop. The only way to combat AI slop is to "copy" production-ready apps that are making millions of dollars.

With that being said the MCP essentially will allow you to pull in directly the design specs from the top hundred (hopefully one day thousand) apps and websites. You will be able to modify them of course yourself but it'll at least enable your agent to have a grasp of what this UI looks like so you can tinker with it for your own color scheme or style from there

I'm working on 3 apps (Zig core, C FFI, Windows/Mac frontends) that haven't been released yet.

One verifies the binary data of over 200+ common filetypes, to the extent possible.

Another protects data archives/data collections with some parity, in order to survive a degree of bitrot, for those files that you don't necessarily have on a NAS.

The third is a new kind of archiver that specializes in compressing files that are already internally compressed as part of their spec.

Trivia: Did you know that the now-most-common image format in the world, Apple's HEIC/HEIF, has absolutely NO internal integrity protection, and that you can't depend on a failed decode to detect errors since all binary values are allowed in the stream format?

I’m working on askdiff - a GitHub PR review style web app attached to the same claude code session that wrote the code.

2-3 weeks ago I noticed a bottleneck in my workflow. I was opening big draft PRs to check code written by CC, and then copy pasting diff back to it to ask questions.

So I built askdiff. Any feedback is highly appreciated.

a Golden Speaker technology that would help users adopt a native-like accent faster! contrary to the current norm in the speech-processing field (esp regarding voice conversion), where voice identities are lost, voice identities would be kept.

We generate a "Golden Speaker" for you -> You record yourself saying a sentence (a phonetic pangram), we keep your accent which represents your voice identity but we correct your pronunciation and then you have a Golden Speaker system. This may be in the form of a TTS or a real-time accent conversion technology.

the above has a provisional patent attached to it, but obviously that doesn't mean anything. & because I'm 16 and know very little so far, I'd very much appreciate any input on the above idea (it's currently a waitlist @ https://loxai.tech). esp if anyone's in linguistics or AI, lmk your opinion!

Product : Truly typed is a document writing app which makes it extremely easy to find out how a document was created. Each document carries information such as how much of the content was actually typed, how much was pasted, how many sources were used, how many authors contributed. Each document also carries flags such as verified human, bot detected, Unverified. Unverified is for cases where humans are transcribing text looking at another tab or book. The core thesis of the product is that purely human generated thoughts will matter more and more.

I've been working on (https://www.margarita.run) - If you could write agents as easy as writing markdown

Github: https://github.com/Banyango/margarita

I've always wanted to write a programming language, and AI made that a bit easier. So I tackled a kind of quasi-extension to markdown that lets you control coding agents easier.

Margarita provides two file formats:

.mg — A templating language that renders dynamic prompts to Markdown. Extends Markdown with variables, conditionals, loops, and includes.

.mgx — An agent scripting language that extends .mg with agentic execution: state, memory, tool calls, user input, and more.

That said I'm not sure how useful this thing is since everyone just uses claude code now, but it was a really great learning experience.

I am working on two things in parallel. https://howareu.app/ is the first one. Of course, struggling with the making it publicly known and trusted. ;)

And the other thing I just started is a MCP server that will connect to Java remote debugging entry point. This way I will try to allow Claude to start debugging session by its own. And I hope that in pure back-end logics, it will easily trace and fix bugs. I now do it with log messages, but it is kind of annoying and dirty and error-prone to do it that way. I would like to try an approach that does not mess up the code so much. Let's see how it will go :)

adil_alaoui3• 2 months ago

howareu.app has a really interesting concept +1 Getting trust and visibility is the hardest part, but if people connect with it emotionally, it can grow fast. Keep pushing

sminchev2• 2 months ago

I will :) Sometimes, I really need someone to tell me that it makes sense. I hit so many walls trying to make this idea publicly visible, that I almost become desperate. Most of the time, I am just treated as 'one more intruder'.

I will continue to push forward :)

alexander20022• 2 months ago

I am currently ideating a flow where people can sneak peak into what people in their network/company/worksapce are vibe coding. The basic mvp is to have some bots connected to git repos and analyse readme + code(?) and then create an aesthetic ui/ux on top of it. A business usecase would be to collabrate with people with similar interests/ideas and also pool resouces and not duplicate efforts.

A gamified aspect is to have some sort of token leaderboard and some other quality of life stuff that can make the platform more social

I am a frontend enginner and looking for some collabrators since this would be open source. People can host the social platform among themselves

WE GOT TO MEET JOHNNY VINCENTO. We are sick of the paid puppet scientists spilling lies to the public! There is only one physicist for humanity, the rest are a bunch of athiest demons.Most people like Christ but the media is paid and bought demons as well. So we put on our "Johnny Vincento Rebel Physicist" t shirts and went on a road trip. We met him and I was in awe. His demeanor and eyes were powerful. I felt like he knew everything about me with that commander/drill sergeant look right into my eyes. I felt as though I was in the presence of a Christ personality. One girl fainted. Everyone was in a hysterical mode. Security was there but Johnny said "let them all in." I do believe God did send Vincento after seeing him. He autographed our shirts and books and on my book he wrote, "TO MY FRIEND WILLIAM, THEY CAN'T DO ANYTHING TO US WE ARE THE CHOSEN ONE'S OF GOD WE ARE LIVING IN THE END OF THE WORLD SO MAKE JESUS PROUD. AND HE WILL SAY WELL DONE FAITHFUL SERVANT WELCOME HOME. 2030 IS THE END OF ALL THE EVIL ONES!"

I work at a small security startup on a project im pretty passionate about.

We are building open source tools to reduce how much sensitive stuff and power apps keep in one place.

One project is TideCloak, a Keycloak fork that keeps the familiar dx but changes the security model underneath: https://tide.org/tidecloak

Another is KeyleSSH, a keyless SSH/PAM prototype where there is no private key file sitting around as one thing to steal: https://github.com/sashyo/keylessh

Most of what I'm thinking about now is dx. Security tools dont matter much if normal devs cant understand, debug, or actually want to use them.

I'm continuing to expand my own deep learning library [1] (PyTorch-clone built with Python and Numpy) to support LLM post-training techniques like supervised fine-tuning (SFT) [2] and reinforcement learning with GRPO [3] . 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". Post-training results are still cooking, since training on my MacBookPro is quite slow with "unoptimized PyTorch" :)

cfunderburg• 2 months ago

Various things this month:

- I've got a native, open source MacOS music player/library _finally_ past version 1. (https://bocan.app) That's been an ugly learning curve as I'm both not the greatest Swift developer and still I want to keep adding features that I didn't quite understand at the start like ReplayGain.

- Ongoing maintenance of my badly-named open-sourced tool called Codex (https://github.com/bocan/codex). It's like a file/git based 1 person doc store that I use at work to drop markdown into, display it, with a built-in MCP server that I can use to ask it questions. THAT one is typescript so much easier. But then you have to worry about the constantly shifting sands of outdated and vulnerably dependencies to look after.

Off Net:

- Went to open my greenhouse for the season and found a nest of robins in my trash/rubbish bin. FFS. Now I can't empty it all for a long time, have to time my visits to tend to the tomatoes and peppers, and absolutely not close the doors. Anyone know how long it takes robins to fledge?

I’m working on ZealPHP (https://php.zeal.ninja, MIT), an open-source PHP framework built on OpenSwoole.

The idea is to keep the simple Apache/LAMP style PHP mental model, but modernise the runtime: PHP can handle HTTP, WebSocket, SSE, sessions, shared memory, timers, and task workers from one long-running process.

Greenfield, it's working great. For legacy code, the migration model I’m exploring is:

OpenSwoole front-of-house, PHP-FPM-style back-of-house for legacy code, and a coroutine-native path for new code. Three lanes, one server.

So in one day, all existing traditional PHP apps can have an asynchronous runtime! Hoping that I am laying the right foundations? Or not? Help me understand!

I also made a handcrafted Learn section where you build a small Personal Notes + AI Chat app + Multi-Player Tic-Tac-Toe step by step:

https://php.zeal.ninja/learn

GitHub: https://github.com/sibidharan/zealphp

After feedback from some senior PHP devs, I tightened the framework core and it now passes PHPStan level 10. Actively developing!

Still looking for feedbacks before Show HN

enodesserped2• 2 months ago

Can it be used easily for streaming things other than AI tokens? Long-running progress updates, log tails, SSE for webhook fanout, the OpenSwoole base seems like it should support these but curious how friction-free that is in practice.

sibidharan2• 2 months ago

Yes.. for all! Its a PHP application server! We created a custom C extension to solve all long running caveats, including session support, superglobal support! Its friction free, and coroutines safe!

I'm working on CouponVault

The story behind this app that I get a lot of giftcards - birthdays, holidays, a lot of special - and by the time I'm pretty sure that a lot of them got lost

Because I didn't find any good place that I can store those giftcards over there I decided to create one

So what this app can do?

• Access your coupons on all your devices

• Automatic cloud backup keeps your data safe

• Switch between phone and tablet seamlessly

• Share specific coupons with others

• Create sharing lists for family members

• Set expiration dates and get reminder.

• Mark coupons as used or archived

• Filter and search instantly

• Sort by category, store, or expiration date

The app is designed to be offline-first, so if you afraid of storing your coupons online, you can use the app offline and all of your data will stay in your device (sharing functionality will be disabled)

Give it a try and let me know what you think!

A collaborative environment for rapid-iteration on the first 20% and last 20% of feature development.

Agents crank out code fast but the first and last 20% are the bottlenecks. Up front you need to make sure you're building the right thing. At the tail, you need to confirm that it actually made sense and fix any bugs.

With Else every branch you push get a collaborative environment where design, PM, QA and engineers can comment and make changes live until everyone signs off and the feature ships.
