alt Hacker NewsAsk HN: What Are You Working On? (April 2026)
What are you working on? Any new ideas that you're thinking about?
Comments
I recently rebuilt my homelab after moving countries, and in the process updated Proxmox to v9.1.6. Been playing with centralizing my databases into their own LXCs rather than creating an individual one for each application.
When I started doing this, I also decided to try Proxmox's new OCI compatibility, which seems to be working well so far, so I am removing all my Docker VMs and recreating the containers directly on my hypervisor.
A native application (Windows, Linux, MacOS) for music transcription.
It comes with time stretch and pitch shift as most of these softwares do, but it allows you to save loop regions and take notes. It's designed to be a practice session tool.
I'm doing it from first principles, and having fun writing GPU code, platform shims, and squeeze every ms I can to make it fast and smooth.
I will be looking for testers soon. If anybody is interested, hit me up.
Working on (another) build system for C and potentially C++ called 'cbs.h', the idea is to use C to build the project similar to how Zig uses build.zig.
Here's how cbs.h builds itself: https://codeberg.org/Luxgile/cbs.h/src/branch/main/cbs.c
Side project to generate good-looking programs for recitals and concerts: https://concert-programs.projects.jaygoel.com
For people who use Fora for travel, a tool that uses AI to create google calendar events from travel itineraries: https://itinerary.projects.jaygoel.com
A website to filter for high quality information/people, then ranking to find "undiscovered" people, and finally doing a simple LLM pass on quality.
Did a scan of Twitter, results seem quite decent. https://thefourierproject.org/people.
Planning on doing research papers/github next
* fastest human-made object (well, for the time being it's failing);
* this too: https://github.com/bggb7781-collab/lrnnsmdds
* SNN, NLP spiking neural network;
* neurosymbollic code generator (half-abandoned, not quite feeling like resurecting 2010s and amazon alexa is the right choice atm).
Working on testing and monitoring agent-readiness of CLIs with www.cliwatch.com, some interesting challenges in building test suites and analyzing data :)
I've been vibe coding a cross platform desktop app targeting bird photographers, that uses photo metadata and vision ML models to generate an eBird checklist formatted CSV for importing. It can detect and classify many birds in a single photo as well as individual birds. https://github.com/jkanethird/rackery
https://github.com/flippyhead/radar
I can't keep up with how fast things are changing. I built this to scan my AI dev sessions chats, search various places I frequent, and recommend tooling, libraries and all kinds of other things I might want to incorporate into my development practices.
Trying out games posted to HN so i can add them to https://hn-games.marcolabarile.me/
Testing out some ideas to automate data entry workflows from an italian powerlifting federation (FIPL) to OPL https://www.openpowerlifting.org/
https://github.com/allegro-systems/score a full stack Swift web framework with Controllers pattern for the backend and SwiftUI like syntax for frontend code. All renders down to minified HTML, CSS and JS. Includes features for auth, REST, frontend reactivity via signals and more.
I've been writing about interesting books and papers I read for a few years now. I wanted a nice, simple interface to point people to as a "hub" for recommendations that's compatible with a static site.
Here's the MVP interface: https://bcmullins.github.io/reading/
I appreciate any feedback. Hope you find something interesting to read!
I'm working on `tu` (terminal use), which is a way to give agents access to a full blown virtual terminal to operate TUI apps
https://github.com/flipbit03/terminal-use
I'm super proud, because it came to my knowledge that someone at Codex used my tool to debug codex+zellij issues, by running zellij within `tu`, and then codex inside zellij
Got fed up that startups and small companies having to pay for Enterprise level compliance and sustainability tools, to be considered as a supplier.
So built Sustalium (https://sustalium.com) which is designed to be easier and faster for micro-small-medium businesses to comply with majority of compliance & sustainability frameworks.
I recently built Cranki [0], a free little PWA that generates crosswords using your Anki flashcard lists. It's aimed at language learners (who find flashcards boring and crossword fun!).
To be honest I built it just for me and then decided it might be useful for others.
It's all local, no server, no database, etc. Mobile and desktop friendly.
A native Mac app as a modern tmux replacement. I manage agents and terminal sessions across several GPU machines and having it all in one UI has been great for reducing cognitive load. If anyone's interested in being an early adopter, we're at https://haventerminal.com
Using a Muse EEG headset to read brain activity and use that to drive the output of a GAN. Similar to other projects that try to visualise or decode thoughts, but at the moment it's an art project. Obviously quite limited by compute and hardware. I'm sort of looking for collaborators / co-founders / opportunities in the AI + neuroscience + creativity space.
I am building upscpath.com - a platform which has copies of people who got through. I used gemini to extract content from those copies and somehow indexed it all syllabus wise.
After building it for 8+ months I am finally moving towards monetisation. Any books on entrepreneurship would be helpful as i build this.
Still working on improving wasm2go (a Wasm to Go "transpiler"): https://github.com/ncruces/wasm2go
Already using it for my SQLite driver, and already in use by some a few other projects: https://github.com/topics/wasm2go
Still very early, but I’ve been building Market Diary - https://marketdiary.io. Log daily market thoughts, document trades, and review charts all-in one place. Built for solo investors and teams who want to turn noise into alpha. Powered by Markdown, supports file attachment, teams, and TradingView charts. Free to signup. Would love feedback.
I am working on https://github.com/xi/xiio, a minimal async runtime for python. It is mostly feature complete with a fraction of the code of asyncio or trio. It is great fun to get into low level stuff and hopefully it helps me to better understand the finer details of async programming.
I built a document engine for trades and am looking for feedback. I'm happy to give a longer trial and understand better how you are creating estimates/quotes/contracts for your customers. Take a look: documentorium.com - free to use without an account, and get extra features with an account(prefill data, history and more in the future).

I made a launcher app - https://play.google.com/store/apps/details?id=com.nurgasemet... but can't stop thinking that most of people are not comfortable with changing their default launcher.
I'm building inspection software for various industries that are stuck with terrible pre-2010 software, or just pen and paper. Using AI where it makes sense, but not forcing it on users. Already have 5 users trialing the software, they're helping shape the product.
Very fun project, launching this week publicly in the app store.
I am adding another feature to https://jar.tools called Security Scan which scan a jar and finds out if a jar safe to run or not. Direct link to a tool https://jar.tools/jar-security-scanner
Deploy to your own AWS account with minimal config!
- Any containerized app, uses Fargate (no Kubernetes)
- Heroku-like CLI tool with instant console sessions
- Set up SQL/Redis instantly with Heroku-like add-ons.
- Autoscaling, preview apps, audit trail, release approvals.
I'm tired of all the recents npm packages supply chain compromises, so I've written a collection of `sandbox-exec` rules to wrap all the `npm install` and `npm run <script>` of my projects on my machine. It works but it's messy, so now I'm working on a small rust tool that acts as a wrapper and generator for that so that it's nicer to use and can be shared to other people.
I’m building https://runprom.pt. I’ve been enjoying building it so far and it’s amazing to see that there’s people interested in paying for it!
I’ve always had a pet peeve that there’s no a good way to run prompts on a schedule…
I’m trying to polish it up more for a bigger launch in a couple of weeks
I (codex) made a plugin for stremio to stream my collection from real-debrid. I tried existing plug-ins first and non was working. Just prompted chatgpt to refine my initial specs, and asked on another session to build that. And later used codex for the last mile. Nothing fancy though and nothing can be particularly useful to others but damn it was too useful to me and my wife.
I believe soon a day will come when the agents will chat with each other to get things done. Agents running on different machines, behind firewalls, on phones, laptops, servers etc will all want to chat with each other.
So there is going to be a need for Instant Messaging for AI Agents - Launching soon. https://agent-socket.ai
The toolbox for anxiously attached people, like myself: https://www.attachedapp.com
Most iOS/Android mental wellness apps are trying to be everything for everyone, ie general AI journaling or meditations.
By niching down, we can build the best experience end-to-end for anyone that resonates with these particular emotional challenges.
An old school WYSIWYG RAD GUI builder for native applications. Because I don't accept that native app development needs to suck as much as it does.
I am vibe-porting an old game, Knights & Merchants(actually its Delphi rewrite - KAM Remake) to WASM. It's going well, I even have multiplayer working, will release it publicly at some point.
Learned more about WASM, OPFS, JSPI and other exotic browser stuff more than ever, also learned more about pascal than I ever wanted to, but it's been immensely fun.
Working on some improvements to my video platform, https://www.kollaborate.tv . It’s a new video player with side-by-side playback comparison. Claude was really helpful at getting the drift adjustment working because I can push it further than I would be comfortable pushing a human employee in order to get things just right.
I've taken time off work to follow something I've always dreamed of doing. So I'm building Cella, A cross-platform, 3D space MMO game set in a procedural, animated universe with fully composable ships & structures built using functional cells.
I'm looking for artists to help fulfill the vision.
I am vibe coding with Opus 4.6: https://github.com/jftuga/swiftswiss
Swiss army knife CLI tool written in Swift using only native Apple frameworks.
The primary goal of this project is to demonstrate how many Apple standard library frameworks can be meaningfully used in a single, actually-useful CLI tool.
brew install jftuga/tap/swiftswiss
https://aquablue.app - Simple, Reliable AI Automation
https://kintoun.ai - Translate Word, Excel and PowerPoint documents with layout and formatting intact.
https://ricatutor.com - Your AI Language Tutor for YouTube
Podcast and RSS reader
Several other things, a CAD/CAM kernel with a Blender based frontend, a possibly novel strange attractor worth publishing, a git/CI host, an AI/LLM/VM cross platform workspace manager / IDE, shared multiplayer terminals in Minecraft and Godot
I've been building grateful - a social gratitude app.
You write a short entry, keep it private or share it to a circle. A circle is a small private group of your own making — family, close friends, whoever you'd actually want to hear from.
Basically private instagram without all of the strangers and ads. What social media used to be.
I built my own fun t-shirt brand called devopsicorn, no AI used here, I worked with a graphics designer from Spain: https://devopsicorn.com
Fun project playing around with print in demand and Etsy. Now wondering why Etsy became so popular while being tricky and inflexible to use for the seller :-)
Building Ori, an open-source agentic IoT runtime with a Physical Actuation Trust framework.
The core idea: every AI agent acting in the physical world must formally earn the authority to act, tier by tier, from informational alerts through to safety-critical relay control. Runs offline on a $55 Pi.
First deployments are underway in Lagos.
Happy to answer questions about the safety architecture or the offline reasoning approach.
https://motionparty.net/ - A collection of games you control by waving in front of your camera, similar to playstation eyetoy back in the day. It supports 1-4 players.
I think it works quite well so far, but need to tweak the camera algorithm a bit to make the buttons work better. Thinking about more games to add as well.
They say programming is dead... I built an AI Streamer platform that responds to a twitch chat
https://slidebits.com/ai-streamer
Not a trivial thing to vibe code without any domain expertise but this project took me under 2 weeks with a AI coding agent harness I built myself. I use Gemini 3 Flash as my main driver as well.
I'm building https://hyperclast.com/ - "Smart Documents for Teams" ie a self-hostable Notion competitor. And it is much faster! Here is why I'm building it: https://hyperclast.com/about/
Trying to make agent clients on low end laptops like a Celeron 900, not a C++/GTK developer so was trying to do it with python, been brutal trying to build python wheels on the single core 900mhz cpu, might look into compiling on a stronger PC or just committing to C++/GTK. I was able to get it to work on an intel 270.
A game framework for vibecoded games.
Native APIs exposed via Rust, but the core framework is written in AssemblyScript. Games or mods/libraries built in it are also written in AssemblyScript.
It builds as a binary that can run on the various PC, mobile, and web platforms. You run it and you get a claude-code-like console that has access to a sandboxed filesystem to put game code in, and a git repo, all built in.
Been working on a paper that's my attempt to add a meaningful update to macroeconomic theory, specifically around the effects of high-entropy outputs (waste, heat, harmful byproducts) as diminishing GDP and general population health. Working on some studies backed up with data to support. If anyone here is interested in economic theory, I could use your feedback.
