alt Hacker NewsAsk HN: What Are You Working On? (December 2025)
What are you working on? Any new ideas that you're thinking about?
Comments
I'm working on a game for pocketstation (essentially Dreamcast VMU, but Playstation). It has the same cpu architecture as GBA but there are some unfortunate circumstances that requires me to modify LLVM for rust to use. Forces me to learn I guess
I am working on Grog, the “grug-brained” alternative to Bazel. A mono-repo build tool where all you do is provide your build commands and interdependencies and the Grog will run everything in parallel with aggressive caching.
A portable, robust desk cloud chamber with a 10x10cm viewing plate. It's taking ages and having just one AIO cooler wasn't the smartest choice, but nothing else would've fit. It's a way harder project than I expected, at least if you want everything to be vibration-resistant for car transportation and for it to last years. I've learned a ton.
A budget app called Ledga that shows your immediate past and forecast future for people living check to check. Desktop app with companion mobile web app.
site: https://ledga.us/
Subscription and Plaid features coming soon.
Free 60-day trial.
A vetting tool for sellers on Fabebook Marketplace (which we all love to hate) to vet Buyers before they meet them irl. check it > https://webvetted.com/detect/social/facebook
what it does: you enter a name and it assembles an OSINT-style report on any Fb user. its early but it works great.
When I'm not working on college applications, I'm working on my HS senior capstone project: Porting the Bridge Designer[0] to the web. So far we've got bridges rendered statically and the load simulation working in code (no load visualisations yet). I intend to post it here when it's ready.
I’m hacking on different side projects but currently I’m working on developing a platform for helping freelancers or small agencies understand aws costs and optimize their environments
Its been a pain point for a lot of the clients I work with helping them understand and optimize their aws costs
They might get a surprise 1000 dollar bill and won’t be able to understand why it happened or what incurred that costs
A few weeks ago I built a very simple metrics tracker that I had been looking for myself... a middle ground between complex observability platforms and tracking a number yourself and then finding a way to visualise its change over time.
I had had the idea and the domain registered for years and recently just took the leap to put it out there.

We are passionate travelers with 30k km under our wheels and we want consistent information across places we find ourselves at. Now are trying to figure out how to help others.
On a Research Assistant: https://muves.io/
It helps to comprehend research papers (and not only papers - any document on any language) faster.
The tool is free to use, because we have credits from GCP. I guess at some point we'll need to introduce some level of subscription fee to keep it alive and useful, as it uses LLMs and vector search quite a bit.
Feedback is welcome!
Writing articles about how to test frontend apps (mostly react based apps) at https://howtotestfrontend.com/ Adding some final bits to some new vitest browser mode content this week hopefully.
Working on a single-node job scheduler for Linux. Large HPC clusters use schedulers like SLURM or PBS to manage allocation of resources to users, but these systems are quite overkill when all you have is a single node shared by a few users.
I am trying to offload as much of the complex stuff to existing parts of the kernel, like using systemd/cgroups for resource limiting and UNIX sockets for authentication.
Enterprise software for SAP migrations. Thousands of companies need to move from ECC to S/4HANA before 2027, and master data quality is the #1 blocker. Built a Windows extraction tool + web app that cleans and transforms data automatically. What used to take consultants months of manual Excel work now happens in days.
I'm building personal, minimalist, website monitor in Gleam using the Erlang OTP.
In the time-honored hacker tradition of added more problems to the problem i'm trying to solve I'm learning a new language (never done FP before, either), building the product I wanted, using the latest crop of creative tools, and treating it as a little end-to-end business startup too. Launching in January!
A minimalist, drag-and-drop homepage builder for desktop... https://paaage.app
A tool for K8S operators that replaces brittle imperative reconciliation code with type-safe state machines generated from declarative YAML definitions. It also bundles error handling / logging / metrics / traces for state transitions.
Not sure if I'm missing a better tool but trying to keep a good working mental model of this has been a nightmare for the operators I've maintained.
Automating infra and systems engineering through devops agents. Basically solving all the pain points for anyone working in devops, sre, etc.
This started as a funny cli project because I was sick of AWS and Terraform.
Hope to release a public beta next month.
for any more info can also hmu @tekbog on twitter/x
Right now I am working on fixing my PC because it is randomly restarting out of the blue during a video call, or during some coding or when it is left unattended. Highly annoying. Right now I basically ruled out anything but the ram and mobo which would be very costly to fix because of Open AI shenanigans.
I've been on a break from coding for about a month but was last working on a new kind of "uncertainty reducing" hierarchical agent management system. I have a writeup of the project here: https://symbolflux.com/working-group-foundations.html
Devcontainer: makes it easy to start working on random projects without installing a bunch of dependencies on the host computer.
Trying to make document collection a breeze for the last 5 years. Still not quite there, although we're making progress.
We are building a K8s management platform based on AI Agents and smart visualization. It's surprisingly hard to distill common issues down to generalizable agents which can solve real world issues but we've made some very exciting progress in the space.
We're building a repairable and more sustainable e-bike battery (that's fireproof!) at https://infinite-battery.com
Check the fireproof video, it's quite fun haha https://www.youtube.com/watch?v=v0NXXfCA2CY
Home, on going work to get local Kubernetes dev env running as close to a production one as possible - ingress, external-dns, ACME CA, load balancer, Argo, registry, prom-operator etc., running entirely locally. Work, similar but in Docker Desktop on Windows and Mac.
Longer term personal aim is a self-hosting platform based on k8s with straight forward bootstrap, similar to Yunohost but k8s based.
Legal-tech: Using AI to help attorneys bill flat-rate instead of hourly. It's data intensive, but possible if you go through their old time entries and tell them the flat-rate price of all of their hourly work. 93% of attorneys bill hourly, primarily b/c they don't have any sense of the cost of the upcoming work. DM me if you want to work on these problems.
An RSS aggregator app. Open source, self-hostable, and I'm running a free hosted instance at the moment. This is the first time I have ever gotten to the stage of having live users in a prod environment for my own apps. Pretty cool stuff.
Substrata: https://substrata.info/
Open source metaverse. Just added rideable jetskis!
Written in C++ and OpenGL. Works on the web as well via Emscripten, WASM and WebGL.
This live bus map, powered by the UK Bus Open Data Service: https://github.com/adamjames/busmap.
Live instance at https://busmap.tail5c8e3.ts.net/
Bonus data from a local RTL-SDR stack.
I'm working Solarite, a library for doing minimal DOM updates on web components when the data changes. And other nice features like nested styles and passing constructor arguments to sub-components via attributes.
Building Tapistro a B2B Sales Outreach AI Agent.
Simmer - Ship AI-driven change campaigns across fleets of micro-services.
Similar to Claude skills, Simmer lets you run fleet wide code changes consistently across multiple git branches, isolated per environment.
Like my fifth attempt at a multiplayer turn-based cricket game, combining squad management, player progression, delivery/shot deck management, and multiphase ball-by-ball play balancing risk/reward. This time, I'm targeting the web, using Elixir/Phoenix/LiveView and loving the experience.
Puzzarium (https://puzzarium.com), a platform for MMO-style logic puzzle games. I justed launched Every 5x6 Nonogram (sequel to Every 5x5), a collaborative game with the goal to solve every 5x6 nonogram puzzle board.
Building the fndamental human patient representation: https://standardmodelbio.substack.com/p/the-patient-is-not-a...
The patient is not a document - multimodal foundation models for biomedicine. JEPA's working well.
Personal productivity app. Mirrors contents of a file (TODO list and other info) on your phone. You can make a call with Grok to brainstorm specifics. The goal was to remove any friction possible, to make focus easier. https://github.com/predkambrij/focusapp
https://github.com/elliotechne/soc2 is a SOC2 compliance checker using checkov and Terraform. Using it with https://github.com/elliotechne/tfvisualizer.
I'm building ourrhythm.de, a privacy first intimacy tracker spawned from a drunken thought: people buy those erotic advent calendars with 24 toys — do they actually keep up with all 24 rounds? It turned into a site idea.
A dotfiles carrier for SSH session called shittp[1], inspired by kyrat[2]
I wrote a Telegram translate bot that uses Opus 4.5 for outgoing messages.
Super simple, yet it’s already good enough that I’ve had detailed conversations and debates in languages that I don’t speak at all.
Pretty simple, really. Cloud native app that scrapes job postings for higher ed institutions, then send me a daily summary based on a handful of keywords. Mostly targeting something to find remote jobs offered through schools. I like working in Higher Ed and my wife is looking for a remote job. Seems like it should be easy to vibe code and run in a free tier.
Trying to relearn Rust, it's been 2 years since I've used it professionally. I'm writing a book to learn it, and I hope to have it out by Jan 1 2026!
I'm working on my writing, of course. In the latest episode of my life, my mother surprised me with fresh news about the origin of my name: https://rikverse2020.rikweb.org.uk/poem/names
Selection Copilot, a browser extension that help user copy selection to markdown and parse rendered latex formulas.
https://chromewebstore.google.com/detail/selection-copilot/b...
I’m (possibly) over-engineering a new personal site using SvelteKit. It’s a blog + public project tracker. All the site content is created and edited using Obsidian, and there’s a build script that parses all the markdown in the vault when the site is built. I’m planning on working on several new projects next year and wanted a place to document them
Working on a gnome todo list extension, I like to keep my daily todos very close, it motivates me to stay focused.
You can install it from here: https://extensions.gnome.org/extension/7538/todo-list
Ultimate missing person cluster map https://clustermap.io
https://ShipmentPlanner.com It"s a tool to help shipping goods to warehouses for ecommerce (amazon) sellers.
Just made a landing page and then transfered its style to the app using Claude AI. Was so impressed that I paid for a supscription immediately.
Will polish the app and plan to launch next month.
Reimplementing something I originally did in python in rust. Both vibecoded - want to get a better sense of how they compare and whether there is upside to be had from rust typing and „if it compiles it’s probably ok“
Thus far - uses way more tokens and noticing reduced steerability. The linting & fix loop seems much smoother though.
I tried the 7DFPS Game Jam this month, trying to learn a little more 3D modelling, as well as Godot. It was my first time using the engine to produce a HTML5 build.
