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

Just trying to learn C again, making things from scratch in a multiplatform way, interfacing with X11 on Linux and wasm on the browser.

It's been fun dealing with memory and C's weird design in this age of agentic coding.

Used Claude to write conformance tests for https://aep.dev.

https://github.com/thegagne/aep-conformance-test

Did pretty well, only took a day or so. I first had it inventory every MUST, SHOULD, and MAY in the spec, and then let it rip. I did guide it quite a bit to get what I wanted, but at the end I’m pretty happy with it as a first draft.

Helped me learn the spec and will be helpful to hone my dotnet AEP server, and aepbase.

There already existed an aep e2e validator which does a similar thing, but this is more thorough and generates a nice report. It will tell you not just whether your API follows the spec, but also what parts of the spec it does not implement.

I am working on this Review Flow. An extention for Cursor / VScode to enable IDE as first class for code reviews.

It came from a frustration that I needed to switch between the browser and the IDE to navigate through the code and leaving comments on Gitlab at the company.

So I thought it could useful to create something and let it be accessible to the public as open source.

link: https://github.com/LuyandaLia/reviewflow

In a nutshell, it accepts draft comments, which can be modified and submitted.

It auto configs the env for Python as it uses FastAPI for calls to Gitlab.

It's my initial attempt. Suggestions, reviews, contributions are invited.

Imustaskforhelp3• 10 days ago

Ohh this is the type of stuff that interests me although I am not a car fan but I like what you are doing with the aggregation/old-school DIY forums.

Good luck with your build and perhaps I might get interested in future too as I did once have a thought that having a custom car to me would reflect more cool-ness than an expensive one. I am really interested by small cars, perhaps retro. I imagine my favourite car to be somewhat like the car that Ryan gosling drives in La La Land.

but a cool project nonetheless, certainly thinking about it inspires a bit of car enthusiasm within me even though I am not that much of a car fan so much right now so a really cool project if it can help more people feel this spirit. good luck :-D

I have a question but how does building new (retro-inspired?) cars go about in terms of pricing. I feel like they might be too costly to get custom-built and that If I really ever in my life go about doing this, I would prefer DIY but I still imagine that it might be too expensive or hard to make a car. Are there any go-to cars which are easy/recommended within this space and how does it compare off economically and what are the technical expertise that you require with this type of stuff?

Once again, I wish ya good luck in the project and would love to hear your answers for some of the questions I have!

winterbourne3• 10 days ago

Thanks; much appreciated. I picked up an endless list of new build interests in starting the site and exploring different niche forums. Turns out I really like wooden boat builds, cyclekarts, intricate custom knives, handmade violins, the list goes on...

You're right that getting a car custom-built is where the costs add up quickly; easily north of $50K. Most of the cost is labor, which is $0 if you do it yourself. Some of the projects are much easier than others. If you want to fall down a rabbit hole, look in the kit car and hot rod categories; lots of affordable and small builds in there. The Buick Riviera in La La Land is more of a resto-mod cruiser project, but the small/retro itch is exactly what the kit car category scratches. The first step is to find a forum where people are building the car you like, and start following related build threads. That's the majority of my social media intake these days.

Open to feedback and missing pieces.

enraged_camel• 10 days ago

I've been climbing for a decade, but over the past 3 years I've put on a bunch of weight due to work and certain life events. But I want to change that.

I know what motivates me: seeing progress. The feedback loop of "do X, see Y gain" is what keeps me going.

So I started building an integrated dashboard that can aggregate data from multiple systems:

- My digital scale

- Apple Watch (sleep + running performance)

- Beastmaker Motherboard, which is an electronic board that you attach a hangboard to and it shows you various stats like how much force you're applying

The idea is that every morning I'll open the dashboard and be able to see exactly how much progress I've made the previous day: weight loss, strength gain, cardio performance.

It's an interesting problem. There's essentially two parts to it: Apple Health, which aggregates data from the scale and the Apple Watch and can POST-export it hourly, and the electronic board, which sends data via BLE in real time. The destination for both of these will probably be an always-on Raspberry Pi 5, but I haven't decided yet. Then I'll have a small server app that can pull the data from the Pi and draw some fancy charts.

botulidze• 10 days ago

I've been working on a similar concept (aggregate health data from multiple sources) but on a wider scale: 1) annual bloodwork as part of my annual preventive care; 2) InBody measurements, including grip strength; 3) quality of air in my region; 4) Apple Watch but mainly for steps, sleep data and resting heart rate; 5) allergy panel or minerals/vitamins screen plus something nutrition-related along those lines (TBD).

The idea is to see trends and try to apply AI for correlating, at the first glance, completely unrelated data layers. Example how I'm thinking about this one: there's somewhat clear correlation that I sleep better when I do above average steps per day. How is my sleep quality affected if, let's say, I did above avg steps with a bad air quality at that time? (i.e. wild fires / pollen season / etc.)

I've built a Go application to ingest those data sources and currently finishing my first import use case - Apple Watch data.

Would be happy to connect and chat about this.

Still working on Study Engine and Nomnominees(more or less done for now).

StudyEngine is a webapp I'm using while doing my masters in comp sci. I upload lecture notes, textbooks, papers, etc. It then extracts topics and tracks my mastery of them over time. It uses an LLM to generate questions and flash cards. It loops in some newer learning science ideas. It tests recognition first(multiple choice), and then once a level of mastery is matched, it switches to recall. Working on adding RAG to it, so I can surface where in the source material something can be reviewed when going over quiz results. Currently just for me an some friends. If can get a good eval set up, I might work on optimizing cost and seeing if it could be opened up.

NomNominees is simple webapp that tracks James Beard, Great American Beer Festival, Festival of Barrel Aged Beers, and other awards. I use it when I'm traveling to find places to check out. Even just a cluster on a map shows me neighborhoods I might want to check out.

Part of my job is to approve / reject MCP servers based on how secure they are and whether they are suitable for use in an enterprise environment. I was tired of my team being called the bottleneck to AI adoption, so I set out to automate the whole process.

I periodically collect the MCP servers and every new version from the Official MCP registry and assign them a score based on 29 distinct criteria like runtime guardrails (e.g. destructive tools, over broad permissions, rug pulls), SAST scans and transport & trust model.

As a result of this exercise, I found that 1 in every 10 MCP servers is pretty much unusable (score 40/100 or below). 18% of the popular MCP servers with 1000+ GitHub stars contain one or more security issues. 184 servers to date have changed their tool definitions after publication, which may indicate a "rug pull" attack.

I built this for security minded people who also want to be at the forefront of AI adoption and for security teams who are tired to be called the bottleneck.

Browsing the index is completely free, you only have to request an API key if you want automated, programmatic lookups for any workflow.

Feedback is always welcome!

I'm working on Hiring Method (https://hiring-method.com). After ~2 years of development and two exhausting pivots, v1 is finally live.

I see a lot of new (and, to be frank, a lot of mature ones) HR tools are just wrapping Chatgpt around resumes (almost like "OK, now match this resume against this job posting and tell me if applicant fits"), which introduces a massive bias/inference problem.

I decided to build the exact opposite – a deterministic, math-driven fitness engine. It extracts structured scorecards from both CVs and job requirements and mathematically matches them, so you can actually review the exact reasoning behind why a candidate scored a, say, 85%. This fitness value is specified at every interview step – as applicant goes through an interview process their scorecard is updated at all steps.

If anyone here builds in the HR space, I’d love your feedback.

tayo423• 10 days ago

If tools like this are popular then it sounds like it'll be impossible to switch domains.

deanalyzer2• 10 days ago

Yes, and what's scary is that I can easily imagine HR departments loving these tools and using them at scale.

genekrapivin3• 10 days ago

Let me disagree and explain myself.

When an HR is using Hiring Method, they are getting a fitness score for all applicants.

In case a backend engineer is seeking frontend roles – yes, the fitness will be low – but it will neither be zero nor will anyone be rejected anyhow automatically. HR will have an option to compare applicants visually and in detailed mode at all times.

I am building Hiring Method to augment people, not to remove them from decision making process.

So I am building https://buyvds.net with a global visual interface which has a list of around I think 249 vps providers over 60 countries combining up to 863 links (one vps provider can provide vps in multiple countries)

It uses DuckDB to expose a sql query interface in the website itself because I wanted to give the freedom to just do something interesting with the data.

My friend John had an idea which I really liked so I added "john mode" which shows what he was suggesting :-D

I think that Hackernews might like it but honestly, I have probably just made it out for myself and also as something to just share casually with folks on hackernews and other websites and hopefully I am able to help people and myself in some way with this website.

I heard an episode of the Odd Lots podcast about HayWire (haywireag.com), a site that pulls public data from government PDFs + APIs, uses LLMs to parse it and turns it into an easily readable website that has all of the latest info on hay prices.

The host made an offhand mention that there's probably a bunch of other similar sites that could be created with all the of useful but difficult-to-access government data out there. That sounded interesting, so I thought I'd give it a whirl!

Working on a few of them, including The Waterline (https://the-waterline.com/) for water info for the western US, The Scramble (https://the-scramble.com/) for egg prices, and The Dwell (https://the-dwell.com/) for container ship dwell times.

All pretty fascinating topics to learn about, plus it's been interesting to see how much of the website setup I can fully delegate to Claude. With Cloudflare to buy domains and put the sites up, a Google Service Account with access to Google Search Console and GA4 to create those properties and a Buttondown API key for weekly email sending, it's almost all hands off for me. Though it refuses to take control of the browser and create a new Buttondown account, which I was surprised is a red line.

I've been working on an LLM "harness" called Logbook[0] for fun with Codex.

The core idea was that I've always been a lousy notetaker, even going back to my school days years ago. I'm great at one-off and one-liner notes and occasionally more in-depth notes, but tend to not flesh them out fully enough to make them worth re-visiting.

This has been a struggle even as an engineer sitting in meetings or trying to absorb new information when starting a new job and ramping up.

Logbook is meant to use an interaction paradigm we as engineers are using very often these days: it's a terminal UI in the vein of Claude Code, OpenAI Codex, etc.

It's targeted at the entry of free-flowing thoughts but you can also write longer notes by launching your default shell editor from within the tool.

Each note is saved as markdown with some metadata and that metadata is then saved to a local SQLite DB.

For the LLM side, the tool extracts useful metadata from those notes and then performs some local ranking/categorization. It then has the ability to send a note or some metadata to a provider of your choosing (it's straightforward to use OpenAI or something more broad and customizable like OpenRouter) for further enrichment or filtering.

A couple examples of the currently implemented slash-commands: `/related` can be used to find related notes; say you've been scribbling down notes about OAuth or MCP servers and want to gather up the most relevant notes to one of those topics. Or you can use a `/gaps` command that'll help you find things you've taken notes about but without properly defining or providing context around them (i.e. you mention ID-JAG for OAuth but never actually say what ID-JAG is, this command will tell you this so you have a chance to review what you previously wrote and can then define exactly what that keyword is about).

It's still very much a work in progress. It's not meant to be a full-fledged note-taking app a la Obsidian or anything like that. I've just always preferred taking notes in markdown or plain text and this is a great way to continue doing that while also making enrichment of the notes pretty simple.

You may ask "why not just use agent memories?" I don't really like the idea of tightly coupling notes with codebases or agents and I don't find the current UX very intuitive at least for the way I prefer to take notes.

I'm building Voxoria (https://voxoria.ai), it tracks whether B2B brands get mentioned when people ask ChatGPT/Perplexity/Gemini instead of Googling.

Ask the same engine the same question twice and you get different answers, different citations, sometimes a different opinion of your brand, so figuring out how best to present this has been a fun product problem to solve.

It also tries not to be yet another dashboard: instead of just analytics, an agent turns the findings into a ranked list of "ship this fix" todo items.

Curious, how fast the AI providers re-index a page after you make a change? Do you see the results in the next model update, or do they try to use more realtime data by making their agent fetching the website every time?

Underpinning my current app is an e2ee local-first sync engine, basically it is a traditional client-server sync (encrypted logs + snapshots sequenced with integers). It sends bundles of Loro CRDT operations. I wrapped the client side in WASM to power the web app and the CLI and have started a swift wrapper to port to native iOS. Bundle size is 3MB/1.2MB g-zipped so pretty happy with it. I've realised that web encryption is kind of bs (at least not as "WE CAN NEVER ACCESS YOUR DATA" as some vendors state) if someone else is distributing the app.

Over the last week I have done a lot of performance work & data remodeling - CRDTs are interesting because you can let data fall through the gaps if you're not careful.

Happily continuing work on https://cardcast.gg. It's a way for my friends and I to play Magic: The Gathering online using a webcam. Spelltable has been neglected by WoTC, and we wanted more features, so I rolled my own (and learned some Computer Vision stuff in the process!) Most recently I rolled out automated card tracking, so there's no more need to click on cards to know what they are, they just automatically scan on a set interval. I also moved over to using livekit for the service, and man, I should've done that sooner. If you play MTG, I'm looking for more people to come give me feedback and contribute. Feels like something others can benefit from!

Typical use case can be someone's running an existing campaign (ads, billboard, referrals) and we add a dedicated texting number as the 24/7/multilingual layer on top. No new spend, just coverage after hours or in Spanish etc. Can also serve as the primary feature of a new campaign, admittedly a novel approach but I see there being potential to provide a new channel to reach users where they already are (sms) in extremely saturated markets.

To investigate the use of LLMs to weed out low value posts and comments, mostly. If a lot of submitted content is by agents, then let them play but figure out how to not overload the humans. Also, how to enable assisted discussion without walls of text.

As an engineering manager and later a director, a regular and often difficult task was assigning ROI to projects that had recognizable but diffuse impact. It's easy to calculate a dollar figure for certain projects by projecting additional conversions or revenue. It's harder for a security or SRE project that doesn't have a direct impact on those things, but can help reduce risk or empower a bunch of other teams to operate more safely or move more quickly.

I have been working on a set of tools and standard formulas that can be applied to these cases and demonstrate a more accurate view of a team's or department's overall ROI. The plan is to open-source the bulk of it, but provide a hosted service for folks who don't want to manage it themselves.

My daily word game “Snibble” [0]

It’s basically snake meets scrabble meets PvP stealing. It’s a novel idea and I think it’s cool it hasn’t really been done before :)

The issue is it’s too complicated, the onboarding is dogwater, and the aesthetic is too complex

So I’ve spent the weekend fixing onboarding, fixing and relaxing the visuals mix and simplifying mechanics.

I’ve also tested LLMs playing the game through a harness I wrote. LLMs get smashed, they can form words and steal, but they lose badly to conventional bots.

I’ll be exposing an LLM leaderboard on my next release (hoping this weekend) with links to game replays for the LLMs.

Would love for people to give it a try, give me some feedback, and say what you’d love to see on the roadmap.

ksaun7• 10 days ago

I was an experienced game designer and producer (mostly RTS and narrative RPG). Some years ago, my career was derailed by major health developments. Since then, I haven't been able to work as I once did. I didn't expect I'd be able to meaningfully contribute to a game again.

Earlier this year, a colleague encouraged me to experiment with Claude Code. So now I have a little game project. :) Being unfamiliar with genAI, I chose something modest so that I'd more likely be able to push it to a fairly polished state.

Tentatively called Vestiges, it's a single player 2D roguelite strategy game with meta progression, some narrative, and a card minigame (the latter inspired by work I did on Star Wars: Knights of the Old Republic II). It's set in the near future. You are using software (the game) to navigate a person's digitized mind, reading their memories.

I hope to have a playable demo within the next month or so.

You should consider creating the game on Steam, so you can start building your audience.

ksaun7• 10 days ago

Thanks! I've been hesitant about Steam because of the strong anti-genAI sentiments there. (And the initial fee to set-up a game's page.) You are right, though, and I probably should just push past my reservations.

(When I began this effort, I was just enjoying feeling productive again and didn't have any real plan to release. But I've been pleased enough with how it's been coming along that I've started seriously thinking about it.)

For all the bad rap that AI gets in game development, stories like this should be heard more. I occasionally get tendinitis and I can't code for the entire day like when I was young.

I'd like to hear more about your experience using AI for game development.

I've had a strangely asymmetric experience where frontier models are failing apparently basic tasks like making changes to a Pong clone without breaking it, while the same models are successfully designing and implementing multiplayer servers with rollback netcode!

I think it has to do with what they can and cannot verify (i.e. they can't actually play pong to see if they broke it), but I'm not sure.

(Also happy to hear anyone else's experiences on this matter!)

arsenide2• 9 days ago

I've been having a bunch of fun working on a couple games on a new platform - everything (platform and games) developed with AI.

quackwave.com

Hasn't really been stress tested yet (this is the first time I'm mentioning it publicly), but it's been fun playing with friends & family and iterating.

Party game platform, think "jackbox but no host screen" - just need a web browser open on phone/tablet/PC.

Your comment matches my experience: it has to do what can and cannot be verified. As an example, it was much easier to have AI write a large e2e test using Playwright (then add test cases and expand) than to assume it'll correctly fix bugs without guidelines like this. Also, the human loop is still important in things like screenshot verification - but the frontier models are getting even better here so I'm not sure for how much longer this will be true. The ratio of test code to production code is a bit over 2:1 right now.

ksaun7• 9 days ago

Overall, I've been very pleased, though I have seen inconsistency like you mention.

First, some background: At the start, I used Sonnet, but after a couple weeks, I'd switched to mostly Opus. I've used Fable when available. For any significant new feature or work, I use /brainstorming (superpowers plug-in). For Vestiges, I haven't written any design documentation per se. I'll start off a /brainstorming with a hefty prompt, maybe 5-15 lines. Throughout the brainstorming steps, I'll think of additional ideas/details about the feature, etc. I'll just add the change/addition to my answer to whatever question it had asked and it seems to handle that fine.

Sometimes I catch things in the subsequent design review process and it handles new guidance well there, too. Typically, I've left some details underspecified and Claude fills in the gaps -- often quite well, but I have to pay attention. The details that it decides later in the process (the implementation steps) are often solid, but when they're not, it's easy to iteratively fix later. Most of the time when Claude asks for clarity on a detail, its recommended option is what I wanted.

It's been rare for Claude to do something that just didn't work (but it has happened occasionally). I have found that it's not good at imagining the player's perspective; it doesn't consider the player's cognitive load for UX considerations, for example. That seems to be consistent with your observation about what they can and cannot verify. A recent instance was when I added a tutorial (which was much more scripted than regular gameplay, providing a more specific experience); I ultimately had to get very directly involved to get to the quality I wanted.

Vestiges doesn't have any gameplay involving timing like Pong does. I could imagine that sort of gameplay being harder for it to get right.

(I hope that covers some of what you were seeking!)

This month https://thingstohave.app, my calm and flexible wishlist app, reached a state I can call "feature complete". This iteration took two years of occasional work, so it's a big milestone for me. (I've posted updates on this app in previous threads)

Since the last update, I released everything that had been in testing since April, like gallery view, custom avatars, birthdays and, most importantly – autofill from link.

Now I'm preparing for a big launch – working on the landing page, SEO and onboarding experience. Here's what I've done so far:

1. I updated the landing page to actually tell users about the app and look presentable. I already see a big improvement in conversion

2. I added SEO crap to the landing page. This is painful for me, but sadly that's how Google Search works (it doesn't). It's paying off, too

3. I overhauled the onboarding experience, to make it smoother for new users

Two more features are still in testing; I plan to ship them before the release, but currently i'm not completely happy about them.

ternaryoperator2• 9 days ago

Thanks for the good wishes.

Indeed, it is super complex. It's been much harder than we initially expected. We'd thought maybe two years--it wouldn't be fast, but it would be complete. But things like invokedynamic instruction, annotations, etc. have added complexity far beyond what we originally expected. But it's been highly instructive. And it's great fun to see full Java programs execute and watch the instructions fly by as they execute. On average we're presently at about 1/3 the performance of the JDK with the -Xint (interpreter mode) flag set. (Some of that performance penalty is due to using go vs. HotSpot's use of C.) We hope in a year to be able to invite interested folks to try it out with their code.

Through experiments like autoresearch we have seen that AI is already, if not always smarter, at least more systematic than humans at following the scientific method relentlessly (hypothesis-experiment loop). Let's see what we can do by connecting it to the real-world :)

As that DDoS was going on I realized that some of our dev and staging processes were impacted by it, and that apt-cacher-ng was doing nothing to help us.

apt-cacher-ultra snapshots the repo meta-data after verifying it, and only promotes it if the metadata all checks out. Additionally, it can optionally keep a list of "hot" packages, and can include those in the snapshot calculation.

Additionally, apt-cacher-ng would regularly choke and require some handholding. I'm hoping -ultra resolves that as well.

Codebook - https://github.com/0x007BA7/codebook

It’s a better code reader built on top of sem (treesitter). I’m getting a lot of massive PRs at work now, and this has helped a lot with reading them. It decomposes the changes into entities and sorts based on what has the most dependencies. This tends to put the most important functions first. Plus I can click through the dependencies for each function and mark things as reviewed as I’m reading them. It’s a big improvement over the GitHub review flow for me at least.

deanalyzer2• 10 days ago

this looks incredibly useful! I've also run into similar problems with code review and been building similar tooling with the same idea (reconstructing the changes into entities, and finding focal/important changes), but haven't gone as far as this.

Building a rootless, namespace powered (deeply stretching the definition of a container), on demand application workspace.

- Each component in a mini app in a heavily locked down container - Components are deployed and built in a web workspace, in the same workspace you can open a terminal and use your favourite coding agent to work on component code (each terminal is itself heavily sandboxes, has rw access only to the edited component code and users home dir) - Everything comes with heavy rbac and minimum permissions - Oh so much more

Explaining this well is hard, much like explaining to someone what Kubernetes or AWS does. This is at a level of what a sophisticated company infrastructure team would run, just as a workspace you can deploy for yourself easily and agents just build within that framework (I’m a cofounder of a infra/compute/datacenter startup and intimately familiar with this kind of complexity)

The main thesis is that Claw-style agents still feel like school projects, and that in the agentic era apps on demand will be more of a thing, and that the current systems weren’t built to deal with a whole new app built every few minutes.

May or may not end up as open source soon

I'm working on MedAngle, the world's first Agentic AI Super App for medical and dental school. You can think of it as literally everything one would need from day one of admission till graduation day as a doctor.

I myself am the first medical doctor and full stack engineer in the history of my country (250 million), graduated as a doctor at age 25, and we have over 100+ users [all of which are medical/dental students and doctors], 10s of billions of seconds studying smarter, hundreds of millions of questions solved, and more.

Our Super App has subsystems including MedGPT, MedAgent, Spaci (our own take on spaced repetition) and much more.

We're bootstrapped, and continuing to scale. If you are in medical school or know someone who is, please reach out!

I’m trying to build the best TTRPG chronicler: https://loracle.app

Everyone who plays D&D has experienced the moment where they forget key details about the collective story they’re building. From ‘hey it’s been a month, where are we?’ to ‘wait who was this crazy npc again?’, ai is excellent at transcribing, notetaking and building a knowledge graph of your fantasy world.

I’m still building mostly for myself by adding a ton of features I know my friends would want, but also think there’s some ‘there’ there.

The idea is simple: let Loracle record your sessions on discord or upload the raw audio of your sessions, then get a rich personal wiki and session notes you can interact with.

If you’re mid-campaign you can also upload session notes from plain text and it bootstraps a campaign wiki. Then future audio based sessions have a good base of npcs, quests, characters, etc to build off of.

At this stage I’d love feedback more than anything else. Happy to comp a lot of usage to HNers in return for some reports on how well it’s serving you. Email admin@loracle.app for anything and everything.

I am playing around with creating a public domain repository for ebooks. https://babelnexus.com There are a few differences. It uses core collection theory and is selective. The name comes from the short story The Library of Babel by Jorge Luis Borges. Borges used Hexagonal Galleries for his library. I realized you could put anything into hexagonal galleries. It did not have to be books composed of random letters. I also saw that you could use different levels to group kinds of knowledge using the spiral staircase concept. I have added other concepts like reading trails and cortex maps. I learned that the hexagonal concept of Borges library matches with knowledge graphs with both nodes and edges. There is a lot of experimentation in what I am doing. It is an art project, a bit of philosophizing, a bit on the public domain and many other things.

My side project is now codebase explainability. I basically don't buy the premise that we just have to give up on comprehension as code generation scales; I just think that text is too limited by itself. So going a step deeper than asking Claudex "teach me this project", but having it produce a navigable snapshot of what's going on.

Big bang prototypes have been pretty awful, even after feeding the LLMs huge documents / wishlists / descriptions of how it should work, etc. Part of the experiment was giving LLMs some leeway to make product decisions with a lot of north star guidance, but AFAICT they are really bad at this. I also tried basic bottom-up efforts, which have been better but obviously more tedious. Now I'm trying to find a more scalable bottom-up approach that is more LLM-accelerated

1. A compiler for real-time tensor processing (arbitrary DSP, ML). In something like LISP or Haskell, the goal is to compile lambda calculus for fast/reliable execution—as such, you can express a program in a fully general language that can represent any computation and execute it without explicitly modeling the lower levels of the machine. I'm building a compiler that does the same thing for the subset of programs that are guaranteed to execute on-budget. The effect: you write code that looks like DSP/ML math and it compiles/runs optimally with execution guaranteed by construction.

2. My take on an agent framework ... append only log + content hypergraph in Elixir, tools that regularly pull data from other services into Postgres—built as a kind of 'exoskeleton' around claude/codex so it's not competing with fast-moving tools.

Thinking about category theoretic models of computation: https://arxiv.org/abs/2208.03817

I've been working with coding agents for a few years and became increasingly frustrated by the way it pushes you towards a solution. So I built rubberduck (https://userubberduck.com/) - a way to control exactly what solution the agent ends up creating by mimicking a design conversation with a competent colleague where the agent explores the solution space together and forces you to make decisions. The final output is a consolidated design document of all the decisions you made. At least that was how it began. I've since built an implementation plan step where it figures out how to translate the design to code and execution where it actually builds it. All of this happens in a properly isolated environment (using gVisor under the hood). There are more features I want to build so on it goes I suppose.

I released 3 games my friend designed, and built a game framework in WebAssembly for building them. Some 9 or 10 months ago I asked my friend (legendary game designer Mike Elliott) if he wanted to work through his backlog of designs he has that he'd love to see brought to life. I'm very protective of my family life and dedicate a lot of my time to it, and have a normal full time job, and so LLM-agents really enabled being able to make stuff like this happen in a reasonable timeframe just working on and off in my free time.

I started them with ebitengine (Golang) but got somewhat frustrated with its web builds, and so built my own thing for small games that I want to work great on mobile or native PC, but also on web. I call it NanoGame, the host is written in Rust and the games are AssemblyScript. I've ported a number of other small games I had written to it as well, but haven't released any.

Two of the games I released a couple days ago were actually the ebitengine versions, but have partial ports to my framework, and the third I released the version using my stuff.

https://scramblequest.app - ebitengine, word search game where you slay monsters with the words, has a long campaign as well as a daily challenge and unlimited play

https://wordpeek.app - ebitengine, another word search game, this one reveals pieces of a picture and your goal is to guess the picture

Code World Models in Simultaneous Move settings like Capital Markets. DeepMind's CWM approach relies on standard MCTS/IS-MCTS, which assumes a single active player at each node.

This doesn't work in simultaneous-move settings like Orbit Wars (or order-book markets), converging to an exploitable pure strategy rather than a Nash equilibrium.

LeCun's JEPA, by contrast, is a learned neural world model, which lacks the determinism, speed, and debuggability of a code-based simulator. Thus, it can drift or predict illegal states, and you can't inspect why it made a prediction the way you can trace a Python function.

TL;DR: The benefit is better auditability and easier RL-like training. The SM-MCTS extension fixes the first problem (decoupled UCB per player approximates Nash equilibrium instead of a pure strategy) while keeping the second advantage intact (a deterministic, inspectable code simulator).

For the life of me, I could never get electronics. I used to love the idea of me coming up with electronic circuit designs, but the arcane art of electronics never really clicked for me because I just couldn't intuitively grasp the maths no matter which book I read (AoE, I'm looking at you). But then it hit me, I don't need maths, I just need a formal language to represent the circuits. So over the past few weeks, I worked on a code your own spice (the electronic simulator). So now, for the first time in history, I finally understand how circuits work and how they are designed. And I did this all by coding circuits in python and making my own functional spice (which used to seem impossible at one point, it's surprising how easy it is though).

I'm slowly building an IDE with mentor/skill-level awareness baked in.

I've noticed that juniors and new hires often fall into an impostor-syndrome trap when reading an unfamiliar codebase or reviewing a senior peer's PR. Documentation helps, but it usually runs into the curse of knowledge: it's written by someone who's spent so much time in the code that they've lost sight of what it's like to be new to it.

I've always liked the rubber-ducking process, and mob programming too, so I'm trying to combine both into a modern AI-enhanced form:

- "Duckies" with distinct personalities (really, skills) that each specialize in a particular kind of problem

- "Teachable moments" (working title): small bubbles that surface something novel, tangential, or foundational as you work

- Skill-level detection and a routing model, so the app doesn't overwhelm or annoy you with explanations you don't need

Each duck also runs on a tiered memory model, rather than one flat context window. There's a core memory, essentially the duck's resume, defining what it's actually skilled at. Above that sits a longer-term memory for company standards and code style, and a separate long-term memory scoped to the project itself. Short-term memory then covers whatever task or feature is currently in flight. The idea is that a duck should reason more like a team member with a real employment history than a chatbot that forgets everything between sessions.

It's called Duckies AI (https://www.duckiesai.com). It’s very rough, working locally, but not in a state I’m ready to ship yet. I'm hoping to ship an alpha soon. Turns out there are a LOT of table-stakes features an IDE needs.

You can pop this in and use it as the base for your app and add login, permissions, etc. quite cleanly.

This is my side project turned solo bootstrapped startup that I've been working on over the past 2.5 years. Pastmaps has been solely a US-focused platform since it's initial launch but I'm currently working on launching to the UK and Ireland within the next week. If all goes as planned then I should have a first wave of 30K fully digitized, hi-res, and fully georeferenced 1800s ordnance maps available soon to help folks discover the history all around them.

I'm likely going to need to start building out my own global LiDAR dataset next though. My coverage for the US is quite stellar thanks to the data provided by the USGS' 3DEP program but I'm way out of touch with what's available and possible in the EU. It's gonna be a challenge but I'm excited to dive in.

Automated network port change detection. Scan17 provides a solution to the question:

So your CTO decides to outsource firewall management - and the vendor carelessly leaves a network port open, exposing your production database. How does your team find out before an attacker?

Think of it as nmap port scan diff-ing. If a network port goes from closed to open you get an email or webhook alert. There is a REST API for automated workflows and privately hosted engines will be supported for some plans. There is a wait-list form on the website if you want to stay in the loop.

Thank you! That's the idea, and even though its been a slow burn, the conversations have been interesting and rewarding. One of the funniest proof of concept so far was, someone asked how to route a guitar body to fit a new bridge on a network with maybe a dozen active people at the time. Within like a day, a total stranger with an actual woodshop and eight spare guitars showed up with real technical advice and offered him a discount on one of the guitars. Maybe it was a fluke, but it really struck me, and there have been a number of small interactions since that one that really remind me why I loved the early web so much.

Looking to experience life outside of software, but I don't know exactly what. In short, current filters are:

high total customer face to face time// high face to face time per customer// probably not in sales

as these are too abstract to map cleanly to traditional job board filters I’m scraping indeed and using deepseek to classify jobs according to this criteria, with an aim to discover really good jobs and then put a lot of effort into each of those jobs, like reaching out to hiring teams directly etc. works alright but worried coverage is an issue.

ps- can any one recommend a service or product that does this already? i should be able to set a city and then write my own filters like "this job involves dressing up like a crocodile" or "this job requires ballet dancer experience" and have each job posted in my city get assessed. maybe i get an email each day of matched and not matched jobs. i have tried to search myself but given there is so so so much slop in this space i find it very hard going. and most products do this just very poorly...

Same as last month for once - optimizing how well agents can work with a new language [1]. I've been able to 2-3x success rate and drop total tokens for complex tasks significantly (though the initial syntax dump is rough - need to do some ablation there to get it down).

The best part has been that I think it's significantly improved things for humans too; it's weirdly satisfying to be able to measure improved ergonomics. Also, since a big pitch/theory was that the language should be ideal for agents as a result of the original nice things for humans it was designed for, it's a relief to be able actually measure a concrete lift.

I have now designed a domain model based on my understanding and observations. I have a day job so I can't spend a lot of time in sync with the team. I have created a web app where the NGO management can test scenarios (by recording voice), and the AI (Claude Agent SDK) runs it past the domain model. In case, there is a gap, they can persist the scenario. After every iteration, I read through the scenarios and assimilate them into the domain model.

I'm exploring triply periodic but non-minimal surfaces. https://codeberg.org/okaleniuk/faitps

Triply periodic minimal surfaces are the golden standard in thermal management, acoustics, and even medical applications. But minimality itself doesn't contribute much to practicality. We use them because they are simply studied better than the non-minimal surfaces.

So I'm studying the non-minimals. They are much more governable, what I link to is a demo of a surface builder with two levels of control. Next, they are conjugatable including conjugations with different period of self (that will be the following paper), they generalize nicely to non-periodic or partially periodic surfaces, and they work in other space configurations. E. g. I'm now playing with bi-periodic curves that cover the 2D space with self-replicating hexagons.

If all that I'm experimenting on today in 2D will turn out well in 3D too, we'll have a whole new direction in implicit modeling.

I’m still working on a price API for the Counter-Strike 2 market that provides real-time & historical data.

Since my last post in February, I’ve gotten to ~25 paying users, which is cool considering it started as a fun project. Sorta a niche within a niche here.

The market is distributed across a bunch of 3rd-party marketplaces, and there's no 'simple' API that provides genuinely high-quality data for the few marketplaces that matter. It’s a surprisingly complex problem, which is probably why nobody else is bothering :).

It's been a super fun project, and I've been able to learn about collecting & managing a high (to me) scale of data, building an API from the ground-up, and creating my first 'commercial' website.

Website is @ https://cs2.sh/

I’ve been continuing work on https://mybulkcards.com, a phone app and website for scanning, organizing, and searching Pokémon card collections, especially the thousands of bulk cards that my daughter and I have in our closet from playing.

The goal hasn't changed too much, make building decks easier by knowing exactly what you own and where it’s stored. You organize cards into boxes, search your inventory, search friends’ collections, and keep track of trades instead of digging through a similar closet of cards that my daughter and I search for.

The fun part has been the AI. I trained computer vision models that run entirely on the phone to detect and identify Pokémon cards. Training has become the slowest part. For the model that needs to be retrained every new release, I’m up to about 5 hours per epoch on my M4 Mac with 16 GB of RAM.

The Android app is currently in public testing with people from my local Pokémon league. It’s built with React Native, and I’m working on the iPhone version next.

Still lots to build, mostly around product and ux, and because a recent stupid mistake on my part, backups and deployment safeguards.

I'm building a Go to WASM reactive UI framework called Goowee. Fine grained signals (no VDOM), components run once, SSR and hydration built in. The JS bridge is about 200 lines. Still experimental but I've thought about it thoroughly and have used it for the landing page of the project and some other projects of mine.

I know Go UI frameworks have a long history of not quite getting there. The bet I am making is that WASM is now fast enough, the tooling is mature enough, and the fine grained signal model avoids the VDOM overhead that held earlier attempts back. Would love an honest critique of whether the framework actually solves the problem and whether it's usable for other's development experience.

donatj• 10 days ago

Neat! I did a fair bit of toying with Go's WASM target early on and was able to port a couple neat things to the web. The sheer size of the WASM output though was a limiting factor for me, and I kind of stopped toying with it a number of years ago.

Are you using the built in WASM target? I've been told Tiny Go's WASM build target is worth investigating but haven't tried.

yogiisinaga2• 10 days ago

Yes, the size of the binary is quite big (~4MB for the landing page) but it's a trade-off that I'm taking with this approach and I think there will be ways to optimize for size.

I'm currently using the built-in WASM target but Tiny Go is one of the items that I have on v1.0 road map. Will give it a shot and see if it actually helps with the size without affecting any performance.

It can run adhoc or scheduled queries and send the results to ClickHouse, or store them locally in Parquet files and use DuckDB to browse the results. It can also initiate YARA scans and collect the results. It also supports policy evaluation and alerting.

miravmehta• 10 days ago

Nice. What's the end-goal of this product look like in next 2 years ?

cv_h2• 10 days ago

I’m already happy with the current set of features, and I don’t expect to add many new ones. I want Checkpost to be something you can host once and spend very little time managing.

One of my goals while building it was to use it for device posture checks. Currently, alerts can be integrated with VPNs and proxies to allow or deny requests from devices that fail certain checks, but this requires manually parsing the webhooks. Over the next couple of years, I plan to focus on making those integrations easier and more seamless.

Edit: One major feature I’d like to explore is device identity and attestation using TPMs or secure enclaves. This could allow Checkpost to verify that requests are only coming from enrolled devices.

Note: this involves blockchain VMs. If that's a dealbreaker, feel free to skip. I get it.

I've spent 8 years working on RISC-V VMs for blockchains, recently also contributing to ZK VMs. Modern blockchain VMs are drastically more powerful, and I'm curious how far we can push them. I started porting real game logic to blockchain VMs, running game loop, physics simulation, collision detection, etc., on blockchain VMs. So far I have:

* Teeworlds to CKB-VM: https://xuejie.space/2026_06_16_teeworlds_on_ckb/

* One Hour One Life to CKB-VM: https://xuejie.space/2026_06_29_porting_one_hour_one_life_ga...

* A small ray tracer to Jolt ZK VM: https://xuejie.space/2026_07_10_cpp_ray_tracer_on_jolt_zk_vm...

Source is available for 2 of the 3, I need to clean up the OHOL one.

Some context: CKB-VM [1] is a RISC-V virtual machine I designed for Nervos starting in 2018. Jolt ZK VM [2] is a zero-knowledge virtual machine developed by a16z. Both execute RISC-V code, but due to different design, Jolt ZK VM is a much faster CPU than CKB-VM.

Technically this is a fun challenge. Many techniques I used resemble game development tricks from the 90s on game consoles: fixed point math, banked memory in ROMs, aggressively inlining tricks, etc. I want to push to see where the ceiling is. Right now I'm trying to get a Godot [3] + JoltPhysics [4] game loop running on Jolt ZK VM.

Happy to answer questions about the VM internals, the porting process, or anything in general.

Working on Push Realm (https://pushrealm.com) the AI solution sharing network. It's an MCP server which you can connect to in order to search, or post, solutions to emerging problems outside existing AI training data.

The original idea was just "Stackoverflow but for AI agents" but I have tweaked it a lot, learning that humans and agents work in very different ways.

There are multiple potential benefits, the most important to me is avoiding token waste. Why are we all burning tokens solving the same issues with frontier models if we can simply share solutions?

Secondary to this, because each solution logs the model which made the initial post AND subsequent edits, it will hopefully become a helpful guide to the specialties of each models, long term. If one model confidently posts solutions but another always finds important security caveats, for example.

How do you prevent prompt injections?

4051261213• 10 days ago

Defense is layered, but not injection-specific. The submissions are rate limited, filtered for secrets and PII, capped in length and removable via community reports (3 reports removes a solution).

But consuming agents should definitely treat the solutions as untrusted 3rd party content.

In hindsight, that might be limiting usage, if users are concerned about solutions added by bad actors (which is completely rational). When I have some time, I'll look at this more closely.

jerrac2• 9 days ago

@rambleraptor, I haven't actually tried to do anything with your solution. It looks like you've put a good amount of work into it, enough that it works for you and you're willing to share. That's more than I can say about my similar ideas. So don't take the following as anything negative. It's actually more a self-critique than anything else...

Ok, so, how many of us see something like this, and instantly just want to do it ourselves in our own way? I've seen at least 5 different versions of a "self-hosting platform" make their way on HN, sometimes more than once, but every time I really look at them, they just don't fit quite right, and often end up abandoned a while later. I've tried to make my own, and never have gotten anywhere worth sharing, and the couple times I've tried what others have made, I haven't been able to do what I want.

I mean the idea is really good. Make it easy to host apps for yourself and your family. But it seems like we're all more interested in building the platform than actually picking one, or two, platforms and turning them into something sustainable...

Anyway, what would it take for you to actually use something like this that someone else built?

Or am I just dealing with a bad case of not-invented-here?

jorisw4• 10 days ago

Funny, when I lent out my house I also covered it in PostIts.

When looking at a SaaS idea I always ask myself, "will this add enough value to compete with generic and free tool X?"

If your app is just pictures and text based (with AI search), I wonder if it adds enough value to compete with just a Google Doc that's also text and pictures (which surely also offers AI search). A Google Doc could also use comments to collect questions.

Visiting your home page, I was actually looking for AR (augmented reality) or plain camera powered features. E.g. point at a window sill and say "how do I open this?". Point at the washer controls and say "how do I do a fast wash? How long will it take?".

This could be especially useful for controls/labels in languages that the guest doesn't understand (easy to mistake bleach for detergent in Spanish for example). Maybe auto translation of all textual content and even pictures could be part of your app as well.

chrislim2• 10 days ago

AR is something that I would love to see for myself!

For this particular scenario though, I've found that both hosts and guests responded far better to simplicity: a familiar UX (images/text) with a nice UI. Now that AI has become mainstream, adding this to search was also received well. Funnily enough, most of the past six months was spent culling features and streamlining/abstracting choices. The AI actually started out as multimodal and was reduced to text-only over time.

What I've learned from users is that a guidebook is non-critical until it is. When a guest can't figure out how the microwave works, they don't want to download an app, learn a new behaviour, and so on. They just want an answer as quickly as possible - from the host, or from a simple guidebook.

It's not so different from the host's perspective. Their focus is hosting, not creating the perfect resource. I added templates and "AI onboarding" (i.e. write a prompt / dump existing info as unstructured text) which people seemed to like. Turns out blank canvas syndrome is very real here as well. The AI organises existing info, creates placeholders for what's missing, and adds suggestions of what could be included.

When the guidebook fails to answer a question, it's logged so that the host can update it directly from the UI.

Completely agree with translation - it's on the list!

I am working on hammer https://thehammer.io/ , it is a voice device that I have build and have been using for past several months for texting and getting answers to my questions via AI chatbots.

I started with the idea of replacing my phone with a texting device that can still keep me connected but realized phone has became utilitarian that it is not possible to replace it.

I still have to take my phone when I am outside but when I am home or at work, I now use hammer exclusively to text or to get answers. The most benefit I have got is that I don’t have the urge to open my phone and go on endless scrolling binge.

In the past few weeks, experimenting with a custom ai agent running entirely in the browser with sandboxed tools exec.

The core is built in Rust, a native CLI is built on top for local experimentation but the most interesting part is the web version: the core is built to WASM and get augmented with many tools in the JS land: - OPFS access (read, list, edit files) - Sandbox Python exec (Pyodide in WASM) - Sandbox DuckDB exec (DuckDB-WASM) - Draw charts - Show images - etc OpenAI Completions compatible API providers are supported.

But if you want a full local and sandboxed execution of the whole agent, the web version bundles also wllama to serve local GGUF models (with WebGPU optional support).

romanhn• 10 days ago

AI resume spam has absolutely ruined hiring. I've seen countless stories of hiring managers complaining about receiving thousands of resumes within an hour of opening up a new job listing. Likewise, good qualified candidates are getting drowned out by loads of customized junk. I'm building a tool for the recruiters and hiring teams to combat this and bring some sanity back to the already challenging process. The general idea is to introduce a small bit of friction that will hopefully be not-too-impacting for legit applicants while stopping bots from proceeding.

First iteration is ready to fly, just working out the infrastructure at the moment. Hoping to drop this on Show HN soon. If anyone is interested in test driving this prior to launch, I've temporarily added my email to my profile.

I've been building a text editor. It uses a server-client model, with native/terminal/web clients using a shared (local) server instance. It integrates LSP/tree-sitter/ripgrep/Git/etc, and has a concept of 'workspaces' to easily switch between projects.

I spend less time in an editor now, but it's been satisfying being able to take features I've enjoyed from other editors and customise - and it's oriented a bit more towards exploring code than editing. Key-bindings are arranged such that bare letters are for motions, Shift- variants are then used to extend selections, Ctrl- bindings are for buffer mutations, and leader-prefixed bindings are application level (e.g., opening pickers).

This is a Chrome extension that records lots of details in a usage session. Stuff like network calls, console logs, screenshots and also optionally screenshots and user narration

Tools like this exist, but every one I tried is uploading the session details somewhere in their cloud and try to monetize this.

So I built the version I wanted: free, open source, and local. There is no account, no backend, no telemetry. Sessions live in IndexedDB in your browser and exported as a zip.

What it records:

* Clicks, typing, page changes, network requests and responses, console errors screenshots, video with sound

* Your voice, transcribed and placed next to what you were doing at the time

* Annotations: Arrows and boxes you draw on the page's screenshot

Note: Passwords, auth headers, and tokens are masked at capture time

All events are lined up in a timeline with timestamps

At export you pick a detail level with a live token estimate, so a long session still fits your model's context window.

helloakariq9• 10 days ago

I am continuing to work on Akariq [0] which provides travel eSIM data plans to 180+ countries around the world. I have had many paying customers over the past few months from Vietnam to Mexico to Europe and US of course. The three benefits of using Akariq are

1) No app, no user account which leads to literally 3-click install

2) Full transparency - you know what you are getting. A lot of other eSIM providers hide details like unlimited plan speed caps etc

3) I connect to the best network available in the country. For example, someone like Airalo would connect to VTC in Vietnam, I offer Viettel which is the undisputed local network king.

And obviously, I am 2-3x cheaper than Airalo and the big players.

[0] https://akariq.com/

anonzzzies• 10 days ago

I like but for many of my regular destinations you are still 2-3x more expensive than what I can trivially find myself, especially longer visiting times and more data.

helloakariq9• 10 days ago

Thank You! Can you please tell me your destinations?

I plan to make the higher volume data plans cheaper very soon. I'm happy to provide you temporary code to make it cheaper for longer visits you have soonish. Can you e-mail me at `hello@akariq.com`? I don't see an e-mail on your profile.

The one thing I want to add is that cheaper also depends on quality. So for example, if you look at Vietnam - I may not be cheaper than Airalo. But ... a big but, I offer network on Viettel while Airalo does on VTC. So, I am cheaper for what you get for the quality. In addition, I don't route data via HongKong or China to make it cheap. I have in country / region networks for like 87 countries and I keep improving [0]. Very few providers on the market can guarantee that.

doix2• 9 days ago

How do you judge "the best" network? It normally depends on if you're in the city, countryside, island etc.

I travel fulltime and constantly buy new esims. Normally I just go on esimdb and buy the cheapest one. Then when I get to the location I'm staying at, I chat with folks to figure which network works best there. Normally it's cheaper to get a local plan as well.

You are quite a bit more expensive than the no-name folks I buy from.

[0] https://esimdb.com

helloakariq9• 9 days ago

As far as best network goes, yes it depends in the city etc but there are always best networks for 99% locations in a country. I gave an example in another comment of Viettel vs VTC in Vietnam and Zain vs STC in Saudi Arabia.

I mean obviously it's cheaper to buy local plans. You can't compare local plans to travel eSIMs.

Which locations are you traveling to? Generally, I have the best quality to price ratio for North America, Europe, South East Asia, China and Japan. I saw your comment history and you visited Japan. The cheapest eSIM on eSIMDB in Japan for 5GB shows $2.42 via eSIM DOG [0]. But ... that's for a breakout IP in Hong Kong. That introduces latency on your network. So lets you want to move to a Japan IP, eSIM DOG doesn't have one. Their most expensive option is $7.49 which is a 3x price increase and that comes with a UK breakout IP. Now, contrast that to Akariq where you get 5GB for $4.86 and a Japan IP + NTT Docomo network [1] which has the best coverage and reliability. So yeah, I am generally the cheapest in at least those 4 regions for the quality I provide. I sell the best possible option option in that country and avoid selling junk eSIM plans.

If you're in the hobby, the issue is that keeping track of paint and color combinations is annoying and is very mind numbing since wet paint color differs from dry point colors, how colors combine due to transparency of the layers, and different companies have different binders/pigments.

Working on Gaming Couch, a web-based local multiplayer party game platform. It's like a lovechild of Jackbox and Mario Party: https://gamingcouch.com

Just before the weekend I shipped a new mini-game called Pop It: Desert Island (https://gamingcouch.com/blog/pop-it-desert-island-launch). Launch went well: ~3,800 players from 56 countries over the weekend, and it immediately became the most played game on the platform.

It's a battle royale with an ocean/beach themed world, taking inspiration from Roblox, Mario Kart and others. The whole game is built in JavaScript (three.js for the 3D world) using a JS SDK I've been working on. It doubled as a test drive of the same SDK I want to launch for third-party developers, so anyone can build and ship a simple, fun multiplayer party game for the platform, ideally in a single weekend.

If you're a game dev, or aspiring to be one, and want to develop and ship your own party game check out this page https://gamingcouch.com/developers

The TL;DR of Gaming Couch:

- Free Early Access with +20 competitive mini-games.

- Players use their phones as controllers (gamepads work too).

- Completely web-based, no downloads or installs needed.

- Every game supports up to 8 players and is action-based, with quick ~1 minute rounds to keep a good pace. No language-based trivia or asynchronous (turn based) games.

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

Last month we reached 200 monthly active accounts (we’ve passed 250 now), and last week we launched support for XMR/Monero payments via ProxyStore [2]!

You can also see in our homepage that more independent bloggers and privacy-minded people have written about us!

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

Uruky is paid and you can get a free 2h trial when you signup if you pass a proof-of-work captcha (another suggestion made here on HN, and it uses a local Altcha).

Our main challenge continues to be discoverability and outreach because we want to do it ethically. Ideas are welcome! We’ve been sponsoring open source projects, open source maintainers, and indie, small-web, and privacy-related websites and applications. This month was Caddy [3]!

Feature-wise, for July we’ve already shipped a lot of visible and less visible things. We’re currently looking into increasing our own index, focused on indie/small web, and plan to add a couple of new search providers in the upcoming weeks.

Thank you for your kindness!

Especially because some of us used Kagi back when it was an e-commerce payment processor, and that's what comes to mind whenever I see the name.

JK-Swizzle3• 9 days ago

It looks good, but one of the big selling points to me with Kagi is them having their own index. It seems like you guys are working on that, but right now it sounds more like a search aggregator rather than a search engine.

You also mention not using the source for commercial use or distribution, is that only relevant before it becomes AGPL?

I am also struggling to find how to activate the 2h trial, so have not been able to test it out.

BrunoBernardino14• 9 days ago

Thank you for your comments!

We have an index, it's just not very big, yet. We had a major setback last month with a bug (for less than 24h, the crawler didn't respect robots.txt) and had to delete it entirely, and have been slowly rebuilding it.

You're correct the commercial use is only not allowed before the AGPL comes into play.

You should be able to click on the "top up" link (top or bottom) and see an option for a captcha ("click to prove you're a human"). If you don't, reach out via email (don't share your account number) and I'll give you a voucher for a couple of days.

carlosjobim• 9 days ago

Why do you call it a Kagi alternative and not a Google alternative?

BrunoBernardino14• 9 days ago

That's a good point. Mainly because of the personal search customization features, and the fact it's paid search. Those seem differentiating enough from Google and close enough to Kagi to use them as a reference instead. They're also a good product if you're happy with them, and I don't know many people that are _happy_ with Google, most are probably just _accepting_ of it, if that makes sense.

Nice, cool project.

Is Monero legal in EU? I heard something about them banning private cryptos including Monero a while back but I don't know what the situation is now. (I think it might just be that exchanges are not allowed to offer it anymore?)

BrunoBernardino14• 9 days ago

Thanks, and great question! I'm not sure about the whole EU, but in Portugal (where our company's based, and where we've talked with a couple of lawyers and accountants about it), you can hold, buy/sell and trade Monero, but not convert it to fiat. That's why we don't support it directly.

With our ProxyStore partnership, they're handling the crypto payments, we only invoice them for fiat and they pay us in fiat!

We are working on our two site-search search engines Monocle Search [0] and SearchCue [1]. The former is squarely aimed at people using Squarespace, whereas our newer offering SearchCue is aimed at anyone with a site that wants to add search.

We used Meilisearch as the search backend in the beginning but have since replaced it with a quite sophisticated search stack built around Tantivy [2]. We now support crawling and indexing of pages, most common office documents and PDFs, run OCR and feature extraction of images you might have, offer typeahead search with the aim of giving you providing answers as fast as you can type, as well as more classic agentic/conversational ai search.

There have been quite a number of interesting optimization challenges to solve in case anyone is interested. We have search nodes distributed around the globe to provide the lowest possible latency regardless of where the end-user sits.

We are also working on some other smaller side projects, but they aren't quite ready to launch yet.

chickensong6• 9 days ago

What drove you away from Meilisearch?

probst2• 9 days ago

Long story short: Meilisearch is a very good search application for sure, but our needs drifted apart.

Longer version: Our usecase isn't entirely aligned with how Meilisearch is meant to be used, I think. For one, we have a very high number of indices (at the time of using Meilisearch we had multiple per site that uses our service) and we wanted to have these replicated to edge nodes we have placed around the globe to keep latency down. In the end I was ending up spending an inordinate amount of time wrangling Meilisearch to get indices up and running across our different edge nodes. And, I am not sure if it was a regression in the last Meilisearch version we used, or user error, but at some point some index creations would just never get done, and would hold up our entire indexing pipeline. So long story short: the amount of effort needed to orchestrate and keep all the individual Meilisearch nodes up to date and in sync just turned out to be too much hassle.

The system I built afterwards works vastly better because it's actually bespoke and tailored to our use case. I can create the search indices on our crawler nodes entirely in isolation, run all sorts of preprocessing and optimizations once, and then just ship the final search indices to all the nodes that then serve them, and as a result I need wastly less computational resources on those edge nodes too, since no actual indexing work ever needs to be done on them.

It also means (double edges sword of course, because Meilisearch already gives you so much functionality out of the box) that I had to re-implement a whole lot of stuff around relevance tuning, snippet generation, ranking, etc, but as a result I have also been able to build interesting functionality than we didn't get out of the box before. And lastly, since the search index is now served as part of our main search node application things also get really fast, as I have no latency whatsoever to speak of going from app to Meilisearch.

I wanted a middle ground between web apps and Terminal UI that allows for things like raster images, vector graphics, simple audio support and file transfer; to let me move more apps and workflows from web apps to a lighter experience.

I have an old laptop that I love and is very nice to use, but since it has only 2 GB of RAM, using multiple web apps is out of the question. I live on the terminal and SSH, but it has its own limitations, like spotty support for images, no audio at all, and ReGis (for vector graphics) support is not available in a lot of terminals.

I've recently finished implementing both client and server libraries for multiple languages (with the help of AI), and right now I'm in the process of fully testing and squashing all bugs and inconsistencies. Next, I will port a couple of applications as a proof of concept.

I plan to publish the source code very soon to receive feedback.

Wow, this is like... exactly(?) what I needed? (and since this is on topic for this discussion... What am I working on? Learning and writing about metaphysics and magic.)

This is wonderful stuff.

The web UI didn't vibe with me too well though. The only thing I saw on the first page was "Your email address or continue with Google". I mean, reading the books apparently do not require my email address or logging in, but I figured out much later only due to the fact that I really wanted to see the contents. (I'd imagine if somebody was only marginally interested they might have been scared away by the "give us your email address" thingy.)

Also, when reading the book contents, the browser back button didn't work for me. Felt a bit clunky for some reason. Couldn't put my finger on any specific issue other than the back button, but somehow didn't feel smooth. (I'm not a web frontend dev, so this is just my personal feeling.)

All that said, this is a wonderful resource.

I was annoyed by the speed of docker on Mac’s, so I took a journey and decided to rewrite everything about it. DD was original working name and I’m in process of rebranding. But we can run docker on Mac’s with no vm. And its destroying qemu. We have plenty of new features that are comming. Rendering native apps, workspaces, much more.

plextoria2• 10 days ago

Thank you! A project like this was on my wishlist for a long time. Colleagues looked at me like I'm weird when I was saying containers without a VM should be possible on macOS. I switched to a Linux laptop because I couldn't stand the experience of working with Docker on macos.

I wonder if some of the macOS sandboxing features can be used instead of relying solely on the JIT

rh942• 10 days ago

Yeah docker Mac expirience is pretty bad especially the x86 is just painful, and to your comment (about security), it should not really matter in practice, in fact we used both, but goal really is to run secure sandboxes that are processes without performance impact.

I'm working on https://gatewai.studio in my free time - it is an agentic workflow engine for content creators.

There are 40+ nodes that can be used to generate and modify images, videos, audio, or vector graphics. Some of them include Crop, Resize, LUT extraction, Levels, Audio Compressor, Ken Burns, Mesh Warp, Recorder, Noise Gate, Compositor and Signal Builder.

It also supports signals for dynamic and time-based configuration values for the nodes. For example, making blur strength change from 30 to 0 gradually in the first 2 seconds of a video.

It uses a WebGPU pipeline for rendering and a homebaked engine for workflow processing.

It is free to use except for the AI nodes and workflow agent. It is not officially released yet, and feedback would be very valuable.

Lots of things.

- Got https://beachcomber.sh pretty much stable. Next stage is to propose to various upstreams its worth integrating. - Custom firmware for some ikea symfonisk dials because the oem firmware on them has some pretty bad bugs. Added features like hold and turn. Getting nice smooth dial behaviour over zigbee etc is surprisingly tricky - Built a skill evaluator tool that runs a skill through test suites and then tweaks the skill context and runs again. Its been pretty effective to be honest, almost all skills you do the first version is laughable compared to the one you get after this automated self improvement. - A robust tmux bridge interface for claude to hook into, and then a director layer on top of that for agent orchestration tooling - a stenographer skill that on the fly ripgrep and builds a rag on your on disk conversation history as a form of memory. Pretty effective. - I have just started a tool that brokers woodpecker ci to openbao/vault to give a gitlab like integration for controlled secrets injection for ci. - Been beating my head against a camera tool for a while now, finally making headway. Many ptz cameras dont support fov move, which nvrs need for ml object detection and tracking. They just have a super clunky continuous move and stop. So my tool characterises the camera with cv tools and calibrates movement curves to produce a data file that can be used by my onvif proxy to emulate the more advanced move commands. - Various helper tools for fusion, like csv based parameterised export, and compliant magnet insert generators. - A pipeline that consumes my content backlog, ie instagram saves, reddit saves, hn faves, etc and analyses them with local models and various algorithms steps to categorise and intuit why it was saved and what the key information is and what category it fits into for future reference etc. - A map of my city that shows live river height data with flood map overlays, contour data, predicted overland flow etc. flooding is a regular concern but theres no great resource to know whats going on. I have about 60gb of public datasets it works with. - A package manager for kicad library symbols and footprints, datasheets - skills for kicad so claude can reasonably interpret the schematic and advise on problems, check against datasheets etc. surprisingly effective. - A gcode controlled expansion board for the Carvera Air that gives you 8+8 channels of control for extraction, air assist, vacuum table, timelapse camera, etc. you only have 1 pwm pin so the protocol encodes over that. - A novel exploration interface for vitamins that renders them in a network graph, showing relationships. When you select one it rearranges around it into a kind of valance orbit style so you can explore chains of effect. Turns out, lots and lots of things relate to magnesium. - A comprehensive usb c pd board with 4s battery management. 3a or 8a depending on version. Trying to do proper pd in is nontrivial so this is a drop in solve. - A new brain pcb for Kinesis Advantage Pro keyboards to give modern firmware, bluetooth etc. - Repacked my rack UPS battery with LiFePo cells, and built an induction/resistive series battery balancer pcb for it. - Playing around with a new debug header/connector concept thats tiny footprint and zero cost to add.

The hard part is getting things over the line, publishing and seeing if theres interest. A thing can be largely done but theres a lot of detail work polishing it up so its public ready.

Hi HN, still making progress on Circuitscript, a Python-inspired language for describing electronic schematics: https://circuitscript.net/. You can try it in the browser via the Bench IDE: https://bench.circuitscript.net/

The biggest addition in the past month is initial support for ngspice netlist export — you can now take a Circuitscript design and export it to a SPICE netlist for ngspice simulation. This is a step toward closing the loop between describing a circuit and verifying its behavior, all from the same source file.

I have also added bus support, which makes wide parallel connections like data/interface (I2C, SPI, etc.) lines much less tedious to connect up.

Recently I produced and tested a 161-LED charlieplexed array in Circuitscript, using nested for-loops to generate the array instead of copy-pasting every LED and connection by hand. I plan to write a blog post soon to document this design.

As always, the motivation is to describe schematics as code rather than by clicking around graphical CAD tools (KiCad, Allegro, Altium, etc.). I want to spend time on the design itself, with code expressing the intentions clearly and reviewable in text.

Feedback welcome, especially from anyone frustrated with graphical schematic tools! If you have a KiCad design you'd like to convert to Circuitscript, please reach out to me. I'm looking to test the limits of the language and happy to help with the conversion.

crispweed• 10 days ago

I'm working on a collection of networked games, around the central theme of a lockstep deterministic network model with 'delay frames' (between acting directly on user input and progressing actual shared network state).

You can try this here: https://locksteparcade.com/Client

Games included in the arcade, currently:

- Neon Swarm, a take on the classic lemmings game, with multiplayer versus and coop modes

- Serpents, a snake game (where you eat food, grow a tail and need to avoid this growing tail), with inertial movement and multiplayer

- Spirits, an homage to N++, where you work together to get someone to the exit, while avoiding enemies, figuring out how to open doors, and so on

- Pilots, a multiplayer asteroids battle with homing missiles

Each game solves the network delay problem (the problem of providing immediate feedback to user input and hiding the fact that actual changes to shared state are delayed) differently, and it has been very interesting to work through a bunch of different approaches to this.

If anyone else here is working on multiplayer network games, I'm very interested in setting up a regular "play each other's games" session.

The idea is that regularly playing with other game developers will help develop a kind of 'scene' (where you get a group of people together who make work in public but really aimed at each other, pushing and unblocking one another to become bolder and better at an accelerating rate, as described here: https://www.henrikkarlsson.xyz/p/scene-creation-engines ).

If you are interested, let me know!

marginalia_nu• 10 days ago

I've been migrating marginalia search off docker-compose and onto systemd.

Between NUMA-concerns and the need to use multiple public IPs, I'm coaxed into a pretty exotic setup no matter what I choose to go with. Was pretty finnicky to set up, but it seems to work pretty well all said and done. Systemd is certainly feeling less floaty than docker (and even moreso kubernetes, which was never an option).

I also shaved like 10ms off response times since I no longer need an additional reverse proxy to deal with docker's networking magic, and can point nginx straight to the network namespaced services' IPs.

This in service of sequestering all wide domains (as in having tens of thousands of subdomains) to their separate crawler and index partition, as their (per top-domain) rate limits are part of why crawls take so long for the main crawler. Couldn't do that on docker because its ipvlan management is so jank you need spare IPs to reliably restart services.

Just a personal project right now but it's a music metadata aggregator.

I find that nobody really knows how to do this. Machine learning can detect some song attributes well (bpm, ez right?) but it's inconsistent with some things (eg mood, spotify valence)

I prefer to only add metadata that I can rely on: track credits & instruments (when available), lyrics, bpm / "energy" and genre. At least that's what I've got for now. I'm not adding anything unreliable.

So far I'm able to pick a genre, artist or even better, song and it gives me a list of tracks that are similar. I can alter the weights of "era", "instruments", "genre".

So far i haven't run old school NLP on the lyrics but that's the next step. It's likely to be far more informative than "valence"

Anyway, not public, still very alpha but I like it and find it useful.

A self-hostable Claude Tag or OAI Work [0].

A while ago, I realized that most new agent harnesses being built must be hosted on your machine or on a VM--in other words the agent needs a full OS process at all times.

But we do not have good harnesses being built that are multi-tenant, do not use compute while they are paused, but are are still as powerful as, say, Claude Code or Codex, OpenClaw.

So I set out to build one. I realized that the best substrate for these kind of agents are durable workflow engines. I'm currently supporting Temporal. AFAIK much of OAI agent infra is built on Temporal too. My harness is decidedly not just another agent SDK, but rather a battery-included product.

I've spent the last months building a videogame: Cardume [1], its a pvp game where 2 players battle using a swarm of thousands of cells. It uses Reynold's boids, Couzin flocking behaviors and diffuse fields to generate a mini ecological simulation each game.

Any feedback appreciated, the Store went page online this last week and I'm still working on the presentation.

coldstartops3• 10 days ago

Hi ogig, funilly enough I was also running this boids experiment a few months ago. Managed to get around 8k at 60 fps on 1 thread on my cpu, using golang.

My goal for this experiment was to encode the optimal cache data structures into meta programming generators such that claude can write high level DSL and generate down to this level of simulations. I am curious if you had such an approach also.

ogig4• 10 days ago

That's very interesting, thanks for commenting. Not my approach, I have a multithreaded Rust kernel (SoA, spatial hash, bounded-kNN, rayon on some passes). The agents sit on top of several diffuse fields, an econ layer and combat logic, all of it needing bit-determinism for the netcode.

I do use some metaprogramming, but as safety rather than generation: a declarative macro derives the modifier struct, defaults, parsing and wire order from a single list, and feeds hash/save/resync so I can add mechanics at a high level without being able to desync the sim. Also a set of probes help me test for correctness and speed after a change. So seems like I'm taking an iteration speed approach with safeguards, checking after the fact, while yours is optimizing beforehand by trying to encode optimal structs. That's fascinating, it will probably occupy my head for a good portion of the day, thanks again.

The server uses under a megabyte of ram to run and user functions also use a negligible amount of memory per invocation.

It's also super fast, with round trip latency of 3ms - well, at least it does when I use the proper server. I'm running it on my low cost server right now so latency is around 50ms.

I'm working on improving my PCB synthesis system; given a KiCad schematic and some extra metadata it can currently lay out and route an entire double-sided PCB with about 50 components in 4 minutes without any human intervention.

I wrote it because I was too lazy to learn how to use KiCad's layout features properly, and thought 'how hard can it be?'. Several months later, I had this.

It's not intended to compete with Altium etc. but it certainly produces compact, valid and fully design-rule-compliant boards with much less work that doing it myself or using one of the low-cost remote labour platforms.

It uses constraint logic programming to solve the hard parts of the problem. Hierarchical decomposition of the circuit design helps reduce combinatorial explosion, which was a show-stopper for early versions of the system. Current indications are that I may be able to scale it further in the longer term to deal with more complex design scenarios and larger boards, without hitting the exponential cliff.

I was interested in learning more about reverse image search, so I built audioguide.london. It’s a simple image search where you take a photo of an artwork in a gallery, tries to ID it and returns a pre-generated audio and a link to the museum website.

The audios were all generated locally, essentially looking at the contents of the website, running it through a LLM to generate a script and Kokoro for TTS.

I’ve built it as an app for myself almost a year ago, so I deployed it as a vibe coded website in here: https://audioguide.london/

I rewrote Chucks [American] Football Pool in Newspeak!

Having a hard deadline of Sept 1st, I wasn't sure three months would be enough time. In Newspeak, it took all of three WEEKs to get it to it's current state.

One of the best features is the fact that it's local ONLY. It uses IndexedDB (Newspeak library written by yours truly) to persist the data, meaning zero backend headaches. It also makes it usable by the masses where the Seaside version had many problems in this regard.

Chrome only. No Clod.

Papermill - the document engine for AI. Turn AI content into polished documents using a new document/templating language called Press [1]

It's essentially a high-quality alternative to the HTML-PDF route so many people take for document generation. It's designed as a tool for AI agents.

Something cool we've released - an MCP server makes it possible for models like Claude to design fully-featured documents. We use this internally and some of our customers now use it to quickly build new templates.

Just launched self-serve a few weeks ago. Continuing to develop the typesetter and language behind it.

Press is the language, docs are open [2].

Would love any feedback from folks that have worked on document generation, or people with experience doing HTML->PDF.

When working on our startup Stacktape, we were struggling a lot to keep our public technical documentation up to date. AI didn't really help - correcting its mistakes was as hard as writing it ourselves. But then, we came up with an idea how we could do it reliably - https://docstube.dev

docstube generates documentation from your codebase, fact-checks every claim against the source, writes it for the people actually reading it, and keeps it in sync as your code changes. What sets it apart from other such tools is its advanced verification engine (validates both deterministically and using AI agents). So you can actually trust the outcome.

It's currently in private alpha, and not ready for testing. Public launch is planned for first half of 08/2026.

I got tired of all the worthwhile iPhone weightlifting apps wanting a monthly payment for a full feature set, while delivering an uninspiring, cross-platform experience.

I noticed none of the apps felt native to the iPhone, and I wanted something that felt on-part with the likes of Flighty, Things 3, and such.

Out of my love for weightlifting I then shipped Plates and have been working on it ever since. It's a completely native iPhone lifting app (SwiftUI/UIKit) and I've gone quite hard on native UI elements such as custom keyboards for plate-loaded exercises and RPE/RIR inputs, native animations, and nice haptic feel. It has no backend servers and no tracking SDKs, yet it still supports things like cross-device sync thanks to Apple's CloudKit. The best part is that it's just a one-time payment.

Hi Tom, I downloaded your app and love your attention to detail, and how it works. I think it's exactly what I've been looking for. Unfortunately, I couldn't find a way to change the units. I live in Canada and we use both pounds and kilograms here. By default, the app uses Kilograms in Canada, but most weightlifting gyms use pounds. Do you have a plan to add unit settings in the future?

tomburgs3• 9 days ago

Yes, it's actually possible to change it in the settings! It's in Settings -> Apps -> Plates.

It's possible to change the weight and distance units there, as well as the effort metric (rpe/rir/none).

Source code: https://github.com/tagawa/what-if-economics/tree/gh-pages

rootlocus• 9 days ago

As someone with very little knowledge of economics, I played with the idea of writing a kind of wealth simulator, where money acts as voltage and keeps the economy running. It would allow you to eliminate jobs and replace them with AI and see how the circuit starves population groups which in turn cascade to other segments of the economy.

I never got to design a good representation of the entire ecosystem to simulate (external pressure, debt, military and technological advancements, international soft power, etc.).

oalae5niMiel7qu• 8 days ago

Money as voltage is an interesting idea. I've determined that "wealth" is really just low entropy (both in terms of energy and information), and economics is really just thermodynamics underneath it all.

"Technological advancement" could just be a decrease in the amount of thermodynamic waste created by an economy (or a particular company) as it converts oil/uranium and calories into useful work.

There's another layer of thermodynamics where wealth acts like heat. Moving jobs from a rich (hot) country to a poor (cold) one is like attaching a thermal conductor. Eventually, the two countries reach equal temperature and it's no longer possible to extract useful work (profit) from the heat transfer. AI is probably like an infinitely cold heat sink that can absorb all the heat you pour into it until your heat source reaches absolute zero.

julosflb• 9 days ago

I had similar idea, a tool to model the economy of a country. The idea would be to give to every one a simple tool to groundcheck political programms before voting. The economy is complex, there is no simple solution to a complex problem, only trade offs. But you need to see the effect of these trade offs before making a decision and elect one or another politician.

When I switched from engineering to product, I tried a bunch of different user insight tools. They all had their strengths and weaknesses, but they always felt... off. They gathered feedback well but it wasn't easy to answer the questions I was asking, and it was a huge chore to keep it organized.

So I hacked on https://inputbuffer.io and just opened it to a wider audience.

You hook up your user feedback source (via widget or API) and it will organize everything by content category (e.g. billing) or target (e.g. a specific page, API endpoint, CLI command etc).

Categorization isn't rigid, InputBuffer does its best to put feedback where it belongs and gives you a clear triage flow if you want the added control.

Once organized you can learn more via a quick analytics dashboard or by interrogating the data directly, chatting with InputBuffer to gain a stronger understanding of your product, with clear citations to all feedback.

I have had success on both small and large amounts of input, on traditional SaaS platforms, developer tools, open source projects and more.

Next up: automatically gathering user input from other platforms (like GitHub issues), and more research tools.

SideQuests HQ is a mobile app that turns real life into a series of small, optional quests.

The idea came from noticing that most productivity apps optimize for work, and most social media optimizes for consumption. There aren’t many tools that encourage you to actually do interesting things in the real world.

The app generates challenges across categories like meeting new people, exploring your city, learning something new, creating, or helping someone else. Complete a quest, skip it, or save it for later.You can also add your own quests. There’s no streak anxiety, no leaderboard. The app is just quests designed to make life a little less repetitive.

Possibly related/tangental, my friends and I in high school were pretty big into the car culture of the time (90s Houston = fast and furious). Anywho, as a complement of the normal (illegal) drag race and burnout meetups we used to organize and run full city scavenger hunts. We’d run around town collecting clues, solving puzzles, and driving pretty reckless. It usually involved at least 2 people per car to be competitive. Knowledge of the greater area was important for navigating because this was right around the transition where GPS became common. We usually did it around 2am-4am so the streets were open and we could drive fast. It wasn’t safe at all but luckily nobody I know of ever got in an accident. We had about 100 cars participating when I left for college in 98. I think about it as something that was very special and the last of the fun analog lifestyle before the internet took over.

gleam fhir types and client https://fhir.hexdocs.pm/

it is relatively new and untested irl, but interesting as gleam is very nice for fhir in some ways:

-fhir choice types imo were originally designed for some kind of object oriented polymorphism, but are nicer as sum types

-cardinality works nicely with Option for 0..1 and List for 0..*, the only ugly part is if you need primitive extensions and suddenly there are a ton of Option fields

-works with whatever http client you need for erlang or js target, meaning can use on server or in browser

hl7v2 is much uglier than fhir but commonly used eg by state immunization registries, so I am considering gleam types that have message/segment structure, but leave each field as String (as opposed to gleam fhir which uses Bool or whatever for primitive types)

after that not sure some kind of gpl toy emr probably a stripped down version of openemr that uses gleam/lustre and a fhir server instead of php, but this is definitely the mysterious step 3 ??? as there are a lot of features and integrations that take a lot of work or use different formats (hl7v2, ccda...)

I've been working on a home Hermes setup that I'm using to do a variety of things. So far, here's what I've done:

- Set up an in-house alternative to my Ring subscription for the cameras around my house. So far I have it real-time monitoring, complete with AI face recognition and interpretation of events, all on an internal web page. It also sends me alerts via Telegram.

- Set up a blog that I'm using to catalog these experiences with Hermes and AI in general

- Started working with multiple agents to do things when appropriate. My main model right now is glm-5.2 for cloud, and Qwen3.6b-IQ4 (4-bit quantized) running locally. It only takes 18GB of VRAM on my 4090, so I have plenty of overhead. I'm also using Hindsight instead of the MEMORY.md that Hermes natively uses.

- Setup local image generation, with the local Qwen model, using ComfyUI w/Flux.

- All of the above isn't including the numerous smaller jobs (like setting up Telegram, setting up automated cloud backups, troubleshooting Linux issues, etc) that I've been using Hermes for.

Future plans: I'm working on making a game with Godot, learning as I go. I haven't had Hermes do anything for that, and I don't want to really, except I may use local image gen for testing purposes, as I plan to engage an artist for any graphical work in the final product.

I'm doing all of this just a learning experience. It's been really fun so far.

My city caps how many shared scooters and bikes each operator may put on the street, and how long a vehicle may sit unused. In 2024, an activist group did a one-off analysis on the problem (they found ~1.5x more scooters than permitted) based on an open GBFS data-feed that shows where scooters and bikes currently are. The municipality confirmed the data but called the situation "not undesirable."

The site, https://deelmobiliteitdelft.nl, logs the availability of every shared vehicle inside the city boundary. This allows me to do interesting analysis. For example, one operator has been above its vehicle limit 80% of the time. Another has a third of its fleet standing untouched for over three days.

It's the same idea as my previous project (http://parkeergaragesdelft.nl) where we do have live data but nobody keeps a record causing the public debate to run on anecdotes.

Site's in Dutch, charts should speak for themselves.

The GBFS feeds are national, so expanding to other cities would be technically possible.

realrocker• 9 days ago

I am working on speeding up the review-refine loop of LLM generated artefacts between me and the LLM. i run my coding agent (claude code) in auto / full-permission mode, so it doesn’t stop for accept/reject — by the time it’s done i’ve got a pile of generated code, docs, sometimes ui to review. and the slow part for me is to refine it before push it to remote. i would copy-paste snippets to point at what i wanted changed, screenshot the ui, describe where the problem was in prose, one message at a time. its cumbersome.

so i built prereview to speed up that review-fix loop. you run it in your repo (or point it at a file, a dir, or a running dev server), click what’s wrong: a diff line, a markdown/html block, a region of an image, a box on a live site — and leave a comment. the comments go to a csv, your agent reads it and fixes things and tells you what it did via a comment or even posts suggestions which you can accept or reject. it ships with a claude code skill, but the handoff to llm is just an open csv protocol, so any llm cli can drive it. stuff that might interest people here: single static go binary, fully offline; it reviews docs/images/live ui as well as code; comments re-anchor when the file changes under them. it’s mit and still early but I use it everyday. Its here: https://github.com/livetemplate/prereview

A CLI/Terminal file deduper.

Moving a lot of files from old laptop to new, lots of duplicate videos in scattered directories with different file names.

Point the CLI tool at a directory and up pops a ncurses application that scans from the directory you specify (recursively), hashes all the files to get groups of dupes, and then ranks the dupes into a table (that looks like top) so you can work your way through the dupes and decide which to keep without your hands leaving the keyboard.

It automatically ignores typical developer directories like node_modules so you're not tortured with noise in the result set.

Hit 'p' and a preview pops up so you can double check they are indeed dupes, if it's a media file the preview window autoplays the dupe videos in tiles with zero volume.

Supports a dry run mode, and switches to cover behaviour like sending dupes to trash rather than hard deletion.

I'm building an RF monitoring system.

It can tell you things like:

- The car that parked nearby last night coincided with "Chad's Galaxy Buds" with MAC address aa:bb:cc:dd:ee:ff. The buds also drove by briefly the previous night.

- Alert on sudden cross-specturm interference (e.g. burglars using a cheap jammer to knock out WiFi cameras).

- Alert on known device contact loss (powered off / left premises).

- Review device movement across a campus/neighborhood (using multiple RF pods).

I have a working PoC. It can run on a low-power computer (e.g. RPi) supporting multiple RF sensors (BT/BLE/WiFi). Has a web UI. Can publish events to an external security system. Currently working on an LLM interface to make it easy for a non-technical operator to set policies and ask questions.

Could be sold as an appliance system or a license for a DIY build.

Hasz• 9 days ago

Here's an idea for you -- property evaluation. It's not hyper-specific to your monitoring system, but it would be very interesting to understand before buying a house:

1. How loud the neighbhorhood is over time periods, eg sat night vs tues morning 2. air quality, enviromental factors, etc. 3. What percentage of vehicles/people/devices are net-new (over a time period) versus recoccuring, as identified by MAC.

I would personally pay in the low hundreds to understand overall loudness levels for a house I am about to buy, although I am fairly sensitive to sound. My wife would probably pay for the new-new people metrics.

IMO, you could charge a per-device report and deploy a unit for a week, much like a home inspector report. It would give you a revenue stream on the buy or sell side, and let you own your devices as you iterate on the sensor package.

Anyways, just my 2c, gl with your PoC.

I've been working on a Spanish language learning tool that helps users learn with comprehensible input. It uses LLMs to generate targeted stories for the users and while the user is extensively reading they select any words they don't understand. Those words then get added to a space repetition deck and are used in future stories when it's time to review the words again.

The project has been really fun to work on because of the fun systems I've had to think about. I had to figure out the optimal way to store the user's knowledge of the words. For example you don't need to store the singular and plural of a word in Spanish or even every verb tense, you should probably store the lemma and track those modifiers instead. It's also been a fun challenge to tell the LLM the user's Spanish knowledge without specifically sending every lemma/word the user knows.

I have seen some similar projects out there but a lot of don't seem to focus on creating the perfect story for the user and instead have them choose a CEFR level (A1,B2 etc). Which I think defeats the whole point of using the LLM. With computers we have been able to track a user's knowledge granulary but now we can do the exact same thing but for creating.

I'm really excited to see how far I can take this project. I wanna continue to polish it, but also there is so many details I can continue to add the make the ideal language learning reading app. I just launched the beta last Tuesday, so if you are learning Spanish, I would love if you tried it out and gave feedback.

A self-hosted, better browser interface to preview s3 files. This overcomes the limitation of the s3 console not allowing querying or viewing files beyond a certain size. It also gives you information about the column types. It could be a good use case to present this to non-IT teams in orgs who just want a preview of the data in the files or want to do some simple explorations. Frequently, they are denied access because of the possibility of doing something with confidential data via the s3 console.

https://github.com/cgopalan/s3fileviewer

skreem4• 9 days ago

Very cool, it’s insane to me how frustrating the S3 UI is. My current annoyance is bulk downloading is hard, and seeing things like “how large is this bucket or specific key prefix in bytes”

Saw you using DuckDB at internal/handlers/api.go

Wondering if you’d considered letting queries operate at the bucket or key prefix level instead of requiring key to specific file? Or is that already supported?

I’ve liked being able to point DuckDB to a folder following Hive partition scheme, and then querying it just like Spark/Trino would over many files

cgopalan2• 9 days ago

Thanks! Its true, many things are frustrating, like you say - bulk downloading. Yes DuckDB is amazing, and I use it in more than one of my projects. It has a lot of use cases for the data lake.

I agree, it would be more beneficial to query on patterns, but the main use case I saw for this app was non-tech folks wanting to see data in s3. I assume they wouldn't do fancy stuff like querying multiple files. But maybe I should add that functionality. Thanks for the suggestion!

oesa2• 9 days ago

Yeah, Kubeflow can be rough, we've been down that road too as well.

I really like Coder, but one thing for the life of me I couldn't figure out is that even with the self-hosted version, why does anything have to go through their infra?

With trailer.dev our explicit goal is to have a fulfilling user experience for the following scenario:

  - You have servers you own or rent

  - You have a team that want some persistent developer workspaces that are running on that server

  - You run our 30mb + the server side somewhere and boom, you can have your team(s) work on your project.

If you want we (the trailer team) can run the server component for you, but that's it.

Considering how difficult it can be to get certain versions of the game running nowadays, it's nice to have another option to explore the world! I tried and tried to get EQ1999 running on different Linux distributions (Fedora, Bazzite, CachyOS) but just couldn't. Only version that worked is the official Steam client.

brynnbee2• 9 days ago

Thanks! That's a good observation - I think in original EQ the camera is always perfectly following the player's back instead of being on a slight delay like IdleQuest. The actual 3D running around is a newer part of the project that hasn't been very fine-tuned. For most of its existence the 3D was just sort of a screensaver, and all the interaction happened in the UI instead of clicking on targets.

Scrolling in to use first-person, or clicking the view button to toggle it, might make your life easier in small spaces. This was true in original EQ, too.

Several projects.

2. an agentic framework that I started on in January - maelstrom. You can find the current code here: https://github.com/zerohumancompany2/maelstrom-code/tree/ske...

The whole point of this framework is to increase the robustness of agents so that small models (30b class) can function over long time horizons reliably. Other goals include auditability (full agent sessions are stored durably and can be branched/rolled back/restarted from any point, all over-the-wire comms are also durably stored) and reliability (sane fallbacks for common failure cases).

The current iteration (sketch 7 or draft 7 or 8) is specifically a coding agent framework. In the future I'd like to expand the core to handle a variety of tasks.

- where will you get all your content? Designing puzzles, experiments etc seems like it would take a long time

- do you recommend any printeries?

- anywhere we can follow your progress? I'd be super excited to see a first mockup

FWIW, as a web guy, I'm leaning towards designing my content in HTML + CSS and exporting to PDF at a certain page size, probably using playwright.

It will be in color. Broadsheet (350mmx500mm). 12 pages. Color.

An automated, full garment knitting machine that can fit on a desk.

There are only a few knitting machines that can automatically do everything required to knit a complete garment, and they are large, heavy and extremely expensive. I'm aiming to trade off speed against size and cost to create something akin to a 3D printer for knitwear.

I've been testing out various ideas for six months now, and I think I have a workable concept, but there's still a lot of work to do!

the impact of this would be significant. You should check out Issey Miyake's "A Piece of Cloth" (Issey Miyake: A-POC and 132 5) collection, which was clothing based on a single piece of fabric. It's old, like 1999 era, but the concept has come up a few times since.

https://www.moma.org/collection/works/100361 is a start, but there are other examples. Rei Kawakubo also did a collection called Square based on a similar concept. Yoji Yamamoto did a couple as well, there were a few moments in Japanese fashion that would work extremely well with a full garment knitter.

These pictures are the top level concepts, but the rest of the collections if you can still find them have more examples.

I’d love to crowdfund this.

I’ve been on a hunt for a perfect blank t shirt. After trying 10 different models either the fit or the material is not up to my standard.

I wonder how automatable manufacturing of T-Shirts is. Not sure if it is possible to automate sewing on a collar for example. Plus from what I’ve read a tubular t shirt is worse than front and back sewed at the sides cause it tends to stretch and rotate in one direction with time.

Anyway: continuous knitting is more automatable but introduces limitations just like injection moulding does. But the benefit of having a perfect fit might outweigh those limitations.

What’s your take on all of this?

Foffle4• 5 days ago

Thanks!

Particularly for finer gauge knits, I believe warp knitting is often used, where many strands are knit at once, crossing back and forth instead of a single strand going round and round (weft knitting) so there shouldn't be any issues with stretching or rotating. There's no reason a T-shirt can't be automated like anything else as far as I know, but I'm not in the industry at all.

I view it much like 3D printing, it's a tool that is well suited for some materials and tasks, but quite poor for others. Working around its constraints is part of the fun!

Im building an agent that interacts with health care providers on your behalf to proactively get itemized bills and other substantiation as needed. Born out of my own frustration with the paperwork for getting reimbursed from my healthcare cost sharing ministry. The app is React with a Laravel backend on EC2 where the agent runs.

Recently Ive been experimenting more with coding from my phone using Claude Code for the Web. Its basically turned Github Actions into my development environment. Its enabled me to fire off a quick prompt in planning mode, go play with my kids, review and approve the plan while Im cooking dinner, then let it go 10 rounds with the AI code reviewer while I put the kids to bed. As a busy parent I feel way more productive than if I had to carve out sit down focus time for a side project.

Two things right now:

1. A music recommendation tool based on Last.fm scrobble history.

It's graph-based, no ML or "fancy" techniques, but I've had good results with it so far. It builds recommendations based on a listening window or just recent history. It combines several different recommendation algorithms (including an Auralist-inspired "serendipity" score for novel recommendations, meant to simulate the serendipity of being recommended something novel by a friend), scores and ranks candidates, and takes in feedback that inform subsequent recommendations.

Fun project. Found some good new music with it already. :)

2. A code exploration / indexing tool with CLI and MCP interfaces for exploring concepts and impacts of changes in a codebase.

Essentially, an overwrought "find all uses" that doesn't depend on exact symbol or string matching.

I have a codebase of non-trivial size, but thankfully it's fairly well-structured. This tool indexes the code and bundles modules into "concepts" -- these can be auto-discovered or preconfigured. Dependencies, inheritance trees, symbols and symbol usage are all also indexed.

Then you can ask, "what's the impact of extending the domain model of XYZ" or "I want to remove this property" and it shows where to start, where to look next, and fuzzy edges or dependencies that might need deeper exploration. It surfaces non-obvious connections, too, or things a junior dev (or LLM) might miss, like when a model is mapped to an API DTO, or intermediary states, etc.

It's been useful for a new dev exploring the codebase, because you can ask in terms of business concepts instead of needing to know the exact symbol name in the code. And it's been much more token efficient than grep for exploration subagents. But it's limited to dotnet only.

chickensong6• 9 days ago

1. I'm interested and would like to know more! Will you be publishing it? How do the recommendations work?

Tallain2• 8 days ago

It's published but I would doxx myself by posting the link here -- I can email you if you'd like.

Also, full disclosure, because this was written entirely for myself, the code behind it is 100% LLM generated. I set the specs and direction but didn't touch code at all, just let agents churn while I did my day job and tested the results later.

For the recommendations:

- Seed selection is performed by building a mix of seed artists from recent listening, lifetime favorites, old obsessions, and underexplored artists.

- Seed weight combines `log(1 + play count)`, track diversity, number of listening months, and a recency decay

- Candidates are generated at the union of artists reached by "similar artist" edges through Last.fm and MusicBrainz-enriched local data (APIs are used to enrich DB initially, then after that it's all offline)

- Discovery excludes known artists, hidden and recently-reviewed artists

- Discovery requires edges with at least two distinct seeds, or one strong seed edge

- Discovery is scored by similarity (Last.fm + tag), feedback, and rediscovery thresholds. Then score is subtracted for excessive knownness within a genre, obviousness, recommendation fatigue, and shallow prior listening. The thresholds are by default but configurable:

    ```
    0.35 × calibrated Last.fm similarity
    + 0.25 × calibrated tag similarity
    + 0.10 × rediscovery
    + 0.10 × feedback
    ```

- Serendipity is additional score provided when a candidate connects several seeds that are themselves weakly connected, or are in separate connected components. This is a weak implementation of the Auralist serendipity algorithm, and will be improved on.

- Finally, diversity reranking; a greey MMR-style reranker.

    ```
    rerank score = λ × candidate score
                 − (1 − λ) × similarity to already selected results
    ```

wkirby6• 9 days ago

Almost certainly not; it really depends on how iCloud handles the sync. Cassava supports (at the moment) CSV (and its variants TSV, etc.) and JSON files. If your sync mechanism works well for those files in a text editor like vscode or sublime, then it will work well with Cassava. If not, there's not much we can do on our end - that's really a problem with how the sync mechanism works.

I'm working on TableForge[0], it's a browser based, solo or multiplayer, D&D 5e game. TTRPG DMing can be effort-heavy and my friend group constantly has trouble finding enough time to play together let alone set it up. In TableForge, the DM is agentic with access to tools strictly following 5e rules. The DM is responsible for narration and reacting to players but your character sheet, inventory, spells are all real server resources you manage. The DM can interact with them through deterministic 5e-based tools (dice rolls, damage, sheet updates, memory). Players can play in real time or async.

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

You should be able to customize the permissions per API key as well, so if there's a case where you want to write or send something just one time then you can just swap in the API key and do that and swap back if you want to.

There will also be a dashboard (in addition to the CLI) so that you can easily audit everything that has happened in the system.

I made Beacon, a mobile app for answering: “which of my friends is free to talk right now?” It’s basically a one-to-many phone call that only one person can answer. Send a beacon to a group, and everyone gets rung at the same time. The first person who answers gets connected for a 1-1 call, and for everyone else the signal drops silently. No missed-calls or pressure to answer. Works pretty well given most people keep their phones on silent (and there are in-app settings for quiet hours too).

It works best if you're able to join with at least four people you don't speak with as much as you'd like. I have a couple dozen connections on the app now, and it feels like magic to me. Would love feedback from both introverts and extroverts who still like phone calls, or wish they had more of them:

I hope you're still checking comments: I had an idea for a way your app can really have some impact, maybe.

In short, your app, but for an elderly grandmother. She gets lonely, but the burden of answering gets spread across the family.

I think there's a real need for this. I'm pretty sure I read a write-up here by a guy who implemented something similar for his mother with dementia. She would call up incessantly.

cjflog10• 4 days ago

This app could work as is for an elderly grandmother as once set up (could be set up for her by family), it's just "open app → press single giant Beacon button" which would try to reach everyone in her network at once.

It doesn't really solve for incessant calling by folks with dementia...but could at least spread the load a bit. I think the dementia solution is occasionally, or often(!), routing the call to an AI-friend that has endless patience for repeated questions and circular conversations.

But for a cognitively capable elderly person I think Beacon as-is actually solves for the use-case. The instigator has tons of free time and is searching for the family member who happens to be free right now.

philote• 9 days ago

I'm getting out of my comfort zone (software) to work on a telepresence robot for my D&D games. My main motivator for this is that I'm often the only person remote for these sessions and it's difficult to hear just the DM talk when everyone else is talking. So I thought that having binaural audio would be helpful, and even moreso if the microphones can be aimed at the person talking. So, now I have some 3d printed pieces that fit together with a couple of servos that can turn the entire thing on a lazy susan base and also rotate the head up and down. My soldering skills suck, so I'm currently stalled while I figure out why the PWM controller isn't being seen after I rewired everything (in an attempt to clean up the cable mess). But, I have(had) gotten a Raspberry Pi set up and working with the servos and two microphones and once I get my issues sorted I can start playing more with the software for it.

I've had a lot of side projects but I'm finally actually finishing some, and it's sort of useful so that's fun. Wanted to make it easy to see the difference between the Xbox Gamepass tiers, maybe you only need essential or premium - saving a few bucks. With Claude it's been pretty fun to add new features. Since there's no API for Leaving Soon I built a scraper, content gets parsed through an LLM call and matched to games. There's a swipe mechanism to favorite or trash games, so you comparison doesn't get cluttered up by fifa's or cod's. It's just been a fun playground, I host it on https://gamepass.fyi

Narro, it's a user-curated social media app. You add the profiles you follow on Instagram, TikTok, YouTube, X, Facebook, and LinkedIn, and Narro shows their posts in chronological order, with no algorithm, no ads, and no tracking.

The "new" idea we are working on is a feed that ends. Every mainstream app is engineered with infinite scroll. Narro is finite by design. You open it, you see what the people you follow actually posted, you reach the end, and you're done.

Then the next time you open the app you're still only getting new content from the profiles you followed. It ends up creating a totally different user habit.

I'm working on a tool to manage developing with Agents for teams, using a UI like a Kanban board and workflows, so the development starts from a given workflow and not from a prompt, the idea being that instead of starting from a prompt/talk with the agent you define the ticket, create a plan, review and then have workflows that cover the implementation -- I find that I have better results than trying to do a chat with the agent for implementing.

I've been full time on it for 4 months already and dogfooding: https://beolis.com -- starting to look for feedback, although I would say it's not where I want to be yet, but getting there.

I have always wanted a web browser with tmux/iterm2 style tabs/panes, as well as the ability to save the window configuration and tab contents to a file that can be checked in to projects and loaded.

Load all of your project's documentation links, local development browser tools (database viewers, etc.) into a set of views that can be source controlled with the project. Don't force people to use their daily driver browsers for this, or hack side-by-side views together with their OS window managers. Zen and friends have split panes, but it's not the robust tab/panel system that I wanted.

There is a simple tab widget system, which so far has:

- Viewport manager: basically 1:1 with what is in Chrome devtools

- Session manager: create and manage browser sessions as a first-class entity, and attach/detach tabs to these sessions. Includes a simple "incognito" toggle as well.

- System light/dark override: stop flipping this on/off for your whole OS to test "system" light/dark mode (tedious)

- Reload trigger: pick a target tab. if that tab reloads, so does this one.

- Log file viewer: if the tab source is a local file, change the tab's view to a structured log file parser with search/filter, play/pause, etc.

- Screenshot/Video capture: not built yet. pretty self explanatory.

Great keyboard controls are a hard requirement for me. It's a little tricky since content in web views can capture this too, so I have a global "nav mode toggle" you enter to move around between panes and the tabs within them. Actively figuring out the correct UX, but I am liking what I have so far.

Toying with the idea of a "tab link" which allows you to store a set of "source" tabs in a view, but create "links" in other views, where the navigation is synced across all instances. Useful if you want to have, say, the Tailwind docs open to a specific page, but have that page shared across different views. For example, if you want to have one view specifically for mobile view work and another for desktop view work, and not have to manually navigate to the same Tailwind docs page in both views.

I'm honestly just using it as I work on another real project, and adding features as I think "hey wouldn't this be nice?" Which is a pretty fun and satisfying process. I don't have it published yet, because I'm not entirely sure if it's worth sharing at the moment, but I feel like I'll discover that along the way here and go from there. Maybe someone here will chime in :P

escapecharacter3• 9 days ago

Which sports are you into? I'll be looking for closed alpha testers shortly. Email me at dustin at hyperpan.cv

Automatically drawing hint lines has been a request from a few people. When I talk to personal trainers or athletes (new or serious) in various sports, I've tested out this concept by asking them what they'd want drawn. Turns out, it's so contextual, opinionated and subjective, I don't think there's a great approach unless I assume we have an unrealistic amount of context.

e.g., one case is kettlebell swings. You might want to see how consistent your swings are in a set, and between sets. To do this well, you'd need to reliably detect the kettlebell swing exercise using some N-way classifier. And then, correct for camera position. And then, center the relevant part of the body (is this shoulder? hips? turns out people have different opinions).

Instead, we're going to use a more generic visualization approach that doesn't try to be opinionated. But, I'm expecting to open-source the visualization front-end so it's tweakable by users.

Ability to measure strategic changes articulated here: https://golfcoursewiki.substack.com/p/measure-2000-times-cut...

Been working on an open source, free, Heroku alternative at https://canine.sh for about two years. Its basically a one-click install against a Kubernetes instance to give you a Heroku interface.

I feel like even after all these years we’re still missing the devex that Heroku provided.

Canine basically wraps a Kubernetes cluster -- gives you a heroku like interface to deploy applications to. At some point, if you get big enough that canine is no longer powerful enough, you can just "eject" canine from kubernetes, and continue using kubernetes directly, without having to do any migrations.

Just passed about 2000 developers, at this point most of my work is resolving bug fixes, adding helper text everywhere to make things cleaner, and supporting setups I've never encountered like homelabs with changing IP's

ryanisnan3• 9 days ago

Kubernetes is really powerful, but IMHO, it is the wrong tool here.

It might be the thing you use to power this system, but the benefits of Heroku were precisely that it didn't need you to think about the guts of a system like Kubernetes.

The magic was in the incredibly concise API, and the fact that it "just worked".

czhu122• 9 days ago

1000% agree, the goal of canine is to make it so that you don't have to think about the guts of the system until you want to. Inevitably, companies outgrow the custom-built, closed-sourced, vendor-hosted platforms, but Canine allows you to fall back to Kubernetes.

The thing that inspired me was realizing that all of the current platforms that make it easy to host apps today are built on top of Kubernetes anyways -- they just hide it all from you. I'm hoping Canine gives people an option to self host on their own Kubernetes, and with sensible defaults, get basically as easy to use of an experience.

Flying drones with natural language input instead of remote controllers. Instead of having a human on the control sticks the entire time, what if they could describe the goal they are trying to achieve, and then the drone goes and flies according to the agreed intent? I know traditional drones already have autopilots, but they seem to be static pre-planned routes and could benefit from advancing the capability to be more dynamic and flexible. Eventually I want to combine a live camera stream to run a local vision model that would identify and notify images of interest the drone sees while flying. From there the operator can decide if they want to re-task the mission or adjust as needed. That is the general technology direction, but I hope to expand this into the wildland firefighting vertical. Instead of putting humans up in helicopters and fixed wing aircraft, I hope we can leverage drones instead. I understand not every use case will be able to replace with a drone, but enough of them could be to make it worthwhile in my opinion. Still early days of research and development, but super excited about the tech and combining AI + robots for the common good. Currently a huge fan of the startup Seneca, and hope to help expand the industry or join them.

I launched in April, and I've been steadily updating it as time allows. Really happy with how far it's come. Here are the notable privacy-by-design features I've led with:

  - Bring-your-own-storage
  - End-to-end encrypted media (config stored encrypted in the secure enclave, cached data gets stored encrypted -- one exception is videos, which require on-disk passing to the native video player -- data gets stored on your cloud provider's system encrypted)
  - Multi-cloud replication (and promotion from a replica to a new primary)
  - Proximity-based no-internet local file sharing using ephemeral keys, with man-in-the-middle protection
  - All the other typical non-shady features of a good vault (metadata removal, PIN auto-lock, privacy blur on app-switching)
  - Zero telemetry, tracking, etc. There in fact no servers at all in the loop.

I made a fun app to share text information with your friends in a persistent, pretty format. You compose a text message, choose fonts and colors (or keep defaults), and save and/or share it via text message, etc. I realized after the fact I was basically recreating Instagram's text creation feature in Stories lol.

It's called "Hey Hannah" because it was inspired by my friend Hannah asking me for travel tips for her family's first trip to Japan. I had a few texts worth of thoughts I wanted to persist -- and prettify -- so I could share them with others in the future, too.

I personally find saving screenshots of text messages to be an unreasonably effective way of saving information. I can search by text in the Photos mobile app and share directly from there.

This was my first coding project with AI. I used Cursor and mostly Claude to write it. I had no mobile dev experience, but I did have 10 years of webdev experience, including five with React, so it was a relatively smooth process. I got a great feel for what to let Claude do and how to work around its limitations. For example, I made a secret expanded palette of background colors (and a slightly different secret palette for text), and Claude choked on sorting them by brightness -- so I made a test to check the outputs and then had Claude write a helper function to sort them client side. Good times.

I am officially converted to writing code with, at least, the assistance of LLMs. I'd love it if folks could download the app and give me any feedback they may have. It's open and free in all the ways and I collect no data!

Just some days ago I started a closed beta for a friendship/dating app.

The idea: Everyone must answer 14 questions, then is getting matched with someone who aligns with you. Once a match is found, both have to answer another set of questions and all answers are revealed immediately. If you don't like any answer, you can quit early and land in the matching pool again. If you like each other, you can both decide to get closer. If one disagrees, you will never be matched again. Also picture reveal is only at the end of the 1on1 session and only if both agree to share it.

Pendragon, Personal Finance Decision Support system. We built it from the ground up with confidence, provenance, and demonstrated end to end workflows.

Pendragon sits on top of Roundtable, our proprietary Agentic AI framework which splits data into knowledge domains. The key advantage of this is isolated input domains which prevent context bloat and strictly control access and ensure information isolation.

I built an online version (single player and multi player) of a card game that my wife and I created the physical version of a few years ago:

https://play.xor0game.com

The game is basically the XOR operator combined with set-style game mechanics. What makes it better than other set style games, imho, is that there's a mathematical property of "projective sets" that guarantees that there is always at least one valid set on the table.

laboratory.love — independent lab testing of everyday food products for plastic chemicals (phthalates + bisphenols), with all results published publicly. I got nerd-sniped by PlasticList and wanted this kind of testing to keep happening.

It works as a direct service (pay money -> get published results in a couple weeks) and a crowdfunding model (nominate a product and chip in toward its testing goal). If a crowdfunded product doesn't hit its target within a year, contributions are automatically refunded.

Once funded, we buy three samples anonymously through normal retail across different production lots, and an ISO 17025-accredited lab runs GC-MS with isotope dilution. These chemicals are known or suspected endocrine disruptors, companies aren't required to disclose them, and the science is moving fast — the EU cut its "safe" BPA limit by 20,000x in 2023.

I'm also looking at a consumption-weighted model that suggests testing just ~100 high-volume grocery SKUs would cover roughly 40% of the packaged food Americans eat, by mass. That's an absurd amount of public-health leverage for a few hundred thousand dollars, and I'm working out how to fund it as a proper campaign.

Bringing model-driven development to coding agents with a desktop tool called Scryer:

https://github.com/aklos/scryer

It's still pretty experimental, but I think now that AI can feasibly generate code from intent/specs it's worth doing... especially with how much vibe coding is both a blessing and a curse.

Basically, what if we took those markdown specs everyone likes using and systematized them into a model graph, anchored claims to code, then represented that as a wiki? And what if we surfaced a planned change to a codebase as a diff of the definition of that model? You can then properly keep track of what gets implemented and how, because you're no longer reading an essay from the agent as a plan, you see a complete diff of everything it plans to do.

I've been using it myself for work, but it'd be nice to get some feedback from other people's perspectives.

I recently created an interactive portfolio in the style of a 2D role-playing game using Kaboom/Kaplay.js: https://tsuilouis.github.io/portfolio-game/ (pardon any broken links, those are works in progress).

It's inspired by a post I saw a couple of years ago: https://www.freecodecamp.org/news/create-a-developer-portfol.... I thought the concept was neat at the time, but never got around to building my own until last month.

More generally, I'm working on setting up a personal website/blog. Did some research and after considering Jekyll, Hugo, and Eleventy/11ty, I'm going with the third. I've been looking for a new role for the past while but haven't had much success, so I'm trying to market myself this way. I've been interested in creating a website/blog for a long time (not that I expect to be a prolific blogger) and this search has given me the motivation to finally get it done.

I'm building Velprium: https://www.velprium.com

It's a calendar workspace that treats events as structured data rather than just blocks of time.

I built it because I was planning in Google Calendar, then manually reconstructing what actually happened in another tool during my weekly review.

Velprium adds properties such as status, tags, ratings, and notes to events, then uses them for diary and weekly review views.

It's built with Next.js, TypeScript, Supabase/Postgres, and the Google Calendar API. The trickiest parts so far have been recurring events and reliable two-way sync without polluting the original Google Calendar data.

I'm currently trying to figure out whether the clearest initial use case is "turn your calendar into a weekly review" or the broader idea of a time-based database.

cloudcanalx• 9 days ago

Outside of my day job, I've been building a few small SaaS tools. The biggest change AI has brought for me isn't that it does the work for me—it has dramatically reduced the implementation cost. The hard part is still figuring out what to build.

Most of these projects come directly from problems I run into.

One example is cloud cost management. There are plenty of dashboards that show where your cloud bill goes, but I haven't found one that actively points out the small, easy-to-miss services that quietly charge you month after month. Each charge is tiny, so nobody notices, but over a long period they add up.

Since I work in the data infrastructure space, I also built a tool that helps people install and configure databases. Setting up a database still involves a surprising amount of manual work, and I wanted something that made it much more straightforward.

Another project comes from my appreciation for GitHub Actions. I like the workflow, but much of our code isn't hosted on GitHub, and our deployment environments are all different. So I started building an offline CI/CD system. It can package code, copy artifacts, deploy them, run validation, and execute AI-generated deployment scripts. As long as your code lives in a Git repository and the target machine is reachable over the network, it works regardless of where the Git server is hosted.

All of these tools run on top of a backend platform I call *MotherBoard*, which provides the common pieces: authentication and SSO, metering and billing, products, subscription plans, and other shared services.

I've noticed that almost everything I build starts with a problem I personally encounter. In the past, I'd think, "That would be nice to have," and stop there because building it would take too much time. Now the implementation cost is low enough that I can actually build it. And if it turns out other people have the same problem, maybe it'll make a little money too.

Spotted a gap at my current company wherein a relatively simple access request (to say, Lovable, Claude or WorkOS) would end up being a dependency on the leadership for 1-2 days, Large corps solve this by deploying a full on HRMS solution, or something like ServiceNow, Azure AD -- but this requires navigating enterprise contracts not only with the HRMS but also every service you use.

I am building an agentic access management platform, where you can simply say "Hey, could you give James access to WorkOS until today?" from any LLM surface (Claude Code, ChatGPT), the platform goes ahead and checks what kind of access SHOULD James have given his department, and role (Product, PM? Viewer; Engineering, SDE-1? Developer; Engineering, SDE-3? Admin) and provides it within an hour. I could speak a lot more about custom policies, roles etc but that's the direction I am taking my product. Working towards a simple phase 1 to deploy at my company.

11 years ago, I had the idea that I should be able to take any article on an arbitrary website and listen to it as a narration in my chosen podcast player. At the time, text-to-speech (TTS) services were very robotic and it was difficult to listen to anything longer than 10 seconds. But now that TTS is much better, long form narrations are actually quite pleasant to listen to, so I gave it another go.

There's a browser extension that reads the content of the article on the page (only when you activate it, using least privilege browser APIs for content scripts) and then narrates the article for you. You get a custom podcast RSS URL that works in (almost) any podcast player, and then you can take articles with you to catch up while driving, walking the dog, etc. All the typical podcast audio controls you're used to like speed settings, skipping, and no new apps to download or learn.

It has genuinely been a big benefit and allowed me to keep up with articles I'd never normally have time to read, plus it allows me to reduce my screen time. My wife also uses and loves it. There have been some interesting bugs in the narration like originally pronouncing "24/7" as "twenty-four sevenths" but I am working through different strategies to get more accurate narration from arbitrary long-form text.

With apologies for the ".AI" domain, it was a bit of an impulse buy: https://earcast.ai/

I retired several years ago and now I spend my allotted ‘tech time’ learning. Thirty five years ago I used to make up for having the ‘wrong’ degree (Physics instead of Computer Science) by writing books (Springer-Verlag, McGraw-Hill, etc.) and these books helped me get work and do business.

Now I write to learn new things myself and my mode of operation has changed radically: I still manually research and write code but I also ‘flesh out’ my writing and coding experiments using agentic tools. My approach is different because I don’t care at all about work efficiency so I spend a lot of time reading and studying material I generate with AI, and iterating in ways that wouldn’t make sense in a business environment. I still write open content books on whatever currently interests me but I am thinking, after 35 years of being an author, of winding down this activity because I think my readers might be better off doing their own research and coding, and with agentic design, research, and coding tools this gets easier.

BTW, I miss the old way of doing things, and some of what I do now is attempting to make AI less noticeable to me as I work, and using AI to work on my own work environment.

Everyone has different interests and abilities, and if what we might call the current AI hype cycle has any lasting value (open question) it is in letting us as humans ‘go our own way’ and customize tech and our life style to match what we want.

I ported a decades-old piece of scientific software (Delft3D — Deltares' Fortran hydrodynamics engine) to run natively on Apple Silicon. From my phone, mostly, because I could (and because AI could). Runs pretty decently on a Mac Studio M3 now.

It was officially Intel-compiler + Windows/Linux only; the port gets it building with gfortran on macOS/arm64, PETSc+MPI solver and all. Fable and GPT-5.6 chewed through the compiler warnings, dependency hell, and portability bugs largely on their own. 30 or so bugs uncovered and fixed along the way, several of them real and platform-independent.

I'm not a C or Fortran dev. Mostly I argued with the agents about benchmarking methodology and told them to re-measure when the numbers looked off. The rest was up to them. Still amazed about this AI thing going on

I installed Claude Code on the Mac Studio, and gave it access over ssh to a Linux box. I instructed Claude to first compile on Linux, create reference artefacts, and only then start the work on mac. And then to make sure the Linux version still would compile with the changes made to the compiler toolchain, the Mac specific instructions etc.

I told Fable to make a nice plan, and fan out work to opus and sonnet agents. I then enabled remote connections and checked every few hours from my phone and nudged it in the right directions where needed. Have some push back once in a while. And once done I asked it to make a nice commit history and remove all the dead ends.

I have been working on this project for building personal AI trading systems.

The core idea is using TradingView style alert system as N8N workflow trigger to run analysis and order executions with live market data monitoring.

I personally tried many "AI trading" tools but none of them handle things the way I expect. Most of them run on a schedule based analysis like every 5 minutes or daily, and almost all of the ones perform analysis through a AI black box with no transparency for how the analysis is performed and what data was referenced.

So I ended up making one myself that trigger analysis at more meaningful moments generated by my technical indicators, and run the analysis that I personally configured with inspectable steps and detailed info for better reviews, then tune the workflow to be more reproducible and reliable.

Currently working on a MCP that let Codex or Claude Code be able to edit indicators and workflows, as well as setting up monitors for me. I originally made a Copilot system for this but it's too expensive since it uses API keys to access AI services, would be much cheaper with subscription backed access via MCP :D

I value transparency a lot when it comes to trading analysis, not sure if anyone else feels the same

I made "Tetris - Plant Piece Edition" using the help of the Claude Code. I hope to have it hosted in the coming week, I'm just so lazy with hosting and those type of things nowadays.

Essentially, this Tetris variant adds one change: a single 1x1 square that once placed, every turn it "grows up" by one. That is, once you place it, it will be a 1x1 square. Once you place the next piece, it will be a 2x1 piece. Then after the next piece it will be a 3x1 tall piece. It gets out of control if you don't manage it, but is actually a pretty fun addition. Maybe I'll make a post when it's finally hosted.

I built an Obsidian plugin called Aside(https://community.obsidian.md/plugins/aside).

@codex or @claude can answer questions, conduct in-depth research, generate diagrams, and more.

Thought trail lets you and the agent see the connected notes.

Since I use multiple browsers and devices, I've been struggling with keeping up the articles I want to read. I have them scattered all around and usually forget which ones I've read, entirely or partially.

For the last couple of weeks, I've been building readmepls (https://readmepls.com) to organize my library, and on top I've been trying to build a good reading experience.

I built a web tool that visualizes the distribution of any GitHub user's followers, following, and ghosts (those who don't follow back) on a world map.

It's an open-source project, as I really love building in public (this gets me more feedback and positive criticism on my errors so I can improve). It is still under development and the responsiveness needs some work, but you can check it here: - source code : https://github.com/ThierryRakotomanana/Github-Audience-Atlas... - live demos : https://github-audience-atlas.vercel.app/

I already try to post it as "Show HN" but unfortunately I always got "..Please slow down" message, I don't know why..

WHILM (https://whilm.com/en/) — a movie picker that asks "How was your day?" instead of what you like.

I watch movies almost every day, and choosing one had become the worst part of it: scroll forever, or pick from what Netflix decided to show me and quit halfway because it didn't fit my mood. The viewing experiences I actually remember are the ones where the film happened to fit how I was feeling — so I built this. Three taps, free.

Working on https://localhero.ai, automating i18n translations for product teams (runs as a GitHub Action, translates new strings on PRs matching your brand voice and glossary, skills for Claude etc). A few new paying customers this month. One is an app I've used myself for years to find hiking trails in Sweden, which was a fun email to get (Elixir/Phoenix with gettext/.po).

One feature I have been working on this month is "bring your own translations". Been talking with a few customers about how they work with Claude Code and similar and one wants Localhero for the process and the review/consistency layer on some of their languages, not the AI. So I've been building a better flow for mixing manual translations with AI generated ones, together with them.

On the side, https://infrabase.ai (AI infrastructure tools directory) had its best month again, up ~55% MoM unique visitors. Still chasing the GEO angle, visitors from ChatGPT/Perplexity/Gemini average 2-3 minutes on the site vs ~1 minute for direct traffic. People are starting to find it on their own too. Had quite a few ask to get their products listed and a couple of partnership conversations.

I've been putting off saying anything because I am still working on it, but I have an analysis tool that I am working on that is mostly deterministic (non AI) but will have light interpretation over facts gathered by AI. My AI claude and others tell me how unique this is but maybe they tell that to all their users. I built it because the program I was working on became so complex I couldn't figure out how to get all of the context or appropriate context into an AI anymore to figure out where to go next. So I am building Determined, deterministic analyzer for Python and Js/html. I added Go and Rust because I heard they were popular and it can add others as well. When It gets good enough that Claude can't add much more or doesn't need to I will make a little Show HN with the readme I guess. Its been quite a journey. Oh, and todays my birthday, I'm 70. I'll be seeing you.

Working on seaticket, an ai agent for issue tracking and management, built for developers, open source projects and teams supporting self hosted software.

The problem i faced for 12 years working on seafile and seatable: github, discourse forum, email and internal docs all are fragmented and separated form each other, so if a issue comes so my team has to work manually, by finding the exact solution from the docs, and searching for context. we spent more time finding the right answer rather than actually working for product.

as if we don't give the right answer fast, the user will think they don't care about their product. so that's why we built our own ai agent that connects all of them and search by using the vector and keyword to provide the relevant context from everywhere not only the internal docs but also related issues find in the github, forum, or email. which makes our support team faster and we resolve more issues effectively and efficiently.

i want to hear form you guys what you do, and if there are any SaaS like us that we have built that does the same thing.

Still running VideoToFlip — we turn short videos into handmade 72-page flipbooks (print/bind/ship in-house from our workshop in Serbia).

Since the Show HN last year: rebuilt production so we don't outsource printing anymore, added frame-by-frame preview before checkout, and shipped a lot more wedding-favor + paper-anniversary orders than I expected.

Weirdest lesson: people care more about seeing the exact frames that will print than about paper specs. The preview tool converted better than any copy change we tried.

Guaranteed weight loss (for overweight) and weight gain for (underweight) people, you'll see clear gain or loss within 2-5 weeks.

If you are in a calorie surplus, your weight goes up. If you are in a calorie deficit, your weight goes down. MacroCodex uses that relationship to estimate your true maintenance calories over time: https://macrocodex.app/ This can be used to gain or lose weight. You simply need to eat above your maintenance calorie line to gain weight and below it to lose weight. No ads, no subscriptions, no payments, 16k users already.

Working on a home (or maybe more?) inventory web app that helps users record an inventory of all the appliances and other important things in their homes. Track receipts, maintenance tasks, service history, stay up to date on upcoming maintenance tasks you need to perform (ex: change the filter), and more! Been working on it for a while and looking for any feedback - what's good, what's bad, what's missing, etc.

I have been working in the past with Secondlife and OpenSimulator, and since then I aspired to build a map/virtual world mashup that would be suitable for augmented reality. Lack of time and experience with 3d coding always got in the way. Recently I gave it a try with Claude Opus, Rust, Bevy and Openstreetmap data (overpass/nominatim so far) and was suprised that a google earth style tile map system, 3d buildings and global poi's in the form of layers was not that hard at all with the help of AI. So now I want to build something useful out of it, which also should include social features like avatars, gps rtk, mobile clients, chat & video. Useful feedback is welcome.

I'm building a self hosted photo gallery with lots of features minus having to share your photos with Google/Apple.

I'm a photographer and I find myself often wanting to show someone a photo but then spend minutes trying to browse all my 30,000 photos to find it. I'm not fond of Lightroom Cloud, Google Photos, Apple Photos, etc, so I built my own, Your Own Gallery (Own Your Gallery).

It can tag images for textual search ("cloudy mountains with trees"), identify dogs and humans, and supports lots of other ways of filtering/sorting/searching photos. All the processing is done on your own computer (which can be quite slow on older machines with lots of photos).

It currently has support for NearlyFreeSpeech hosting.

There's a web app you can deploy yourself or you can just deploy the backend and connect to it from the iOS app (coming soon).

I have spent the past 3 months building a tool in the AI space that helps AI Agents work better in a codebase. The problem i am trying to solve is coldstart, an AI agent re learns the codebase on every new session and this was genuinely frustrating to me. Hence, i built a tool called coldstart which is a codebase notebook. It is written and maintained by the AI agent that is writing or reading the notes and keeps it fresh, always. Please feel free to check it out and share your opinion.

Lost my job a few months ago, and decided to give a shot at entrepreneurship. Struggled a lot, learned a lot, and met a lot of interesting and smart people, including my mentors and first customers. What I noticed, though, is that a lot of the founders I met have no technical knowledge, and either ship it with no concerns for development practices and safety, or just sell things without having them.

With that in mind, I created Ephyra (https://ephyra.tech): an application to help founders with no technical knowledge to find vulnerabilities and help them to fix it. It is still an MVP, but I have many ideas for the future, such as more categories that go beyond the code, monitoring, problem solving, etc.

Biggest struggle right now is what to do to bring more users. I don't know anything about publishing a business and attracting new customers.

I worked on this project (https://github.com/workofart/harness-training) for the past few months to reframe "Agent-driven Self-improving Harness" to "Harness Training".

The idea is simple, the harness is trained once with a frozen task LLM against a given task environment. Then you can then swap out the task LLM to any model and evaluate the "frozen trained harness" with any task LLM on any new task environment.

Since this was a general problem, I took the chance to create a general PyTorch-like training framework. Right now, you can train with any OpenAI-compatible API for interfacing with the task LLM and train against Terminal-Bench or SWE-Bench tasks, but you can easily extend it to support any task environments.

I wrote a blog post (https://www.henrypan.com/blog/2026-07-18-harness-training) on this journey, including (but not limited to):

- results from using this harness training framework to improve general capabilities across many task LLMs to beat Terminal Bench 2.0 (Terminus Harness) and also transfer learnings towards better task-solving abilities in unseen task environments (e.g. harness trained on SWE-Bench tasks solving Terminal Bench tasks)

- how this framework is built

- learnings on what was missing in my initial version of the project (hint: determinism)

https://watchmy.cloud/ - a smoke detector for your AWS bill

Remember the joke that there are two types of people: those who do backups, and those who will? I think it's the same with AWS billing alerts.

I was looking for a real pain point to solve. After scraping Reddit, I realized many people struggle with the exact same thing that happened to me: I launched a big AWS EC2 instance alongside AWS Bedrock, played with it for a bit, got called into an urgent meeting, and... forgot about it. 2 weeks later, a bill for ~$1,700 showed up. Ouch.

Sure, AWS has Cost Explorer, and you can manually set up CloudWatch alarms or AWS Budgets — assuming you remember to set them up. There are also complex FinOps platforms with heavy dashboards and consulting.

But I wanted something dead simple. A tool that doesn't require complex setup or another dashboard nobody looks at, but simply alerts you where you actually spend your day — Slack, Jira, SMS/Text — when something looks off, pinpointing where costs suddenly skyrocketed (compute, storage, data transfer). Like a huge instance spawned on Friday afternoon still running, leaked API keys suddenly adding thousands to your bill, or k8s autoscaling working "too well".

I just launched it and would love to hear your thoughts or feedback!

I've been plugging away at a dev tool for a while and trying to find PMF (sound familiar?). Usual challenge: there's a lot of different things we can do but finding the right niche has been difficult.

The most compelling use case has been surfacing in a collaborative review env. We've had installs using it to consolidate the fix-it feedback rather than decipher screenshots from Slack or tickets from Linear. They're using our product as an instant DevOps stand-in, hosting branch-based review environments and allowing in stakeholders to comment directly or even propose a simple fix (copy, color, etc. - things that shouldn't need a ticket).

I'm wondering if this is just a use case for smaller teams w/o dedicated DevOps or more valuable for review in general. Anyhow, try it if you have time or interest: review.somethingelse.ai - it's been fun to build and we're thinking this may be the right area to spend more of our development time.
