Ask HN: What are you working on? (September 2026)

[dead]

I'm building a Python Browser and need your help running agents on conformance tests https://github.com/byteface/chromonic/

cd to tests/layout..

git clone --depth=1 https://github.com/web-platform-tests/wpt.git

tell it to run the tests and fix any issues with layout and append any issues with domonic into the PLAN.md

I'm targetting the CSS2 folder atm.. so you can tell it to switch to any folder within there for now.

Thanks,

I'm working on an app to give me the perfect music/soundscape for the books I read.

The current version understands the chapter and generates looping music that matches the feel of the whole chapter. The idea in the long run is to create a video game like music engine that reacts to where you are in the book rather than the environment like it would in a game. Battle music when there is a fight, calm background music or even a matching forest ambient if the characters move through a forest landscape.

Check if out! It's all free and you don't even need to sign in :) https://booktunes.app/

I am rebuilding (unslopping) an app chaotically made by a non-dev friend using AI, that quickly got to 40ish paying users. This is an app to study for public job exams in a specific territory. Infamously topics are public but their content is not. He found a way to agregate from exams that are made public afterwards, and found sufficient overlapping to slowly build a db of questions and several types of tests: per topic, real exam simulacrum, an algo that tells you what to study, etc. From a dev pov the app is a mess though, includin g broken ui, ad hoc components pn top of libraries with both tailwind and hardcoded css, and database debauchery, etc. I am rebuilding the foundation, respecting his vision, let's see how many users fir the next exam :)
