Show HN: A little physical breakout clone Idea: How about a 5 minute game I can play in my browser and it's actually fun to play. Controls: Mouse or keyboard (left/right, left alt/right alt or A/D), space and esc are pause toggle. Page up / Page Down are next or previous level (if already unlocked). Cheats: Z toggles zapper, M toggles magnets. Debug stuff: I, P, E keys are toggles for various stuff (E lets you change some aspects of physics engine). Game is maybe playable on mobile devices, there is a menu on top right, and then click the circle to select type of control. Physical engine is decoupled from refresh rate and runs at 240 Hz. Fully vibe coded (deepseek, chatgpt), levels are human made with some amount of love. https://brontosaurusrex.github.io/physical/v7/ July 31, 2026 at 08:13PM

Show HN: Supapool – a Supabase per coding agent in ~400 ms hi HN, I built supapool.io, an ephemeral full copy of supabase's services that you can spin up in ~400 ms (Auth, postgres, storage, realtime). so if you run multiple coding agents in parallel in different worktrees, they can now have their own copy of supabase without making changes that conflict with eachother. > why not use supabase docker locally? when I run 3-4 instances locally, my macbook gets hot and sometimes freezes. > why not use supabase branches? branches take minutes to setup, and are designed for persistence. this is expensive, and for a dev environment, it is too slow. > why not use mocks? mocks are bad for agents. i expect agents to test their migrations, SQL against real prod service behavior. agents hallucinate working mocks often. However, upside of mocks is that its faster and runs locally, but with supapool, the upside is less convincing. > how does it work/how is this economically viable? s...

Show HN: Hacker Fables – A satirical cyberpunk novel you can read as a man page The project is entirely open source. It takes a single Pandoc Markdown source file and produces HTML, EPUB, PDF, man pages, GNU Info, an audiobook, an HTML-integrated audio player that highlights the content as it plays, and an MP4 output for the "video audiobook." It's generic enough to be reusable. I plan to use the pipeline for my tech blog later on. The novella contains a lot of programming lore. It's an over-the-top love letter to the old-school Linux programmer and to the craft itself.
