Please provide comment and feedback! I’m especially looking for feedback and music-reactive experiences you’d want next. I'm building a few other 3d visuals in addition to fireworks.

Show HN: Watch random code typed out on an MS-DOS IDE

Hacker News - Mon, 07/27/2026 - 12:18am

As a software dev, I really enjoy having live coding videos playing in the background while I work. But it's surprisingly difficult to find hour+ long videos of coding without commentary on Youtube.

What I really wanted was an infinite coding video, so I built one. Pick your IDE/monitor/ambience of choice, hit the Screensaver button, put it on a second monitor or TV, and enjoy infinite coding ASMR.

Hi HN,

I built CarbonSheets over the weekend.. a simple and free cheatsheet portal where you can host and share your documentation and cheatsheets directly in your own GitHub repository with minimal setup.

Key Features: Self-hosted content: Keep your cheatsheets in your own Git repos. Developer UX: Built-in keyboard shortcuts, customizable view modes, and a distraction-free Zen mode. Rich Formatting & Tools: Powered by a flexible JSON schema with an in-app editor and schema validator. Support mermaid JS, Syntax highlighting, callouts, results section etc. Exporting: Export cheatsheets directly to PNG or PDF.

Links: Live App: carbonsheets.vercel.app Instructions and Clone-able GitHub Repo to host your own: github.com/elnoxvie/carbonsheet

(opinion) I'd love to hear your thoughts on the app!

Show HN: Injectable time and timers with custom Date types for TypeScript

Hacker News - Sun, 07/26/2026 - 11:49pm

I find TypeScript js/node environment is missing a Time-Provider (just like *.*NET TimeProvider for instance ships with its framework).

So for this purpose I built a small library (@time-provider) tailored for js/node environment.

Obviously the goal is to both avoid using global monkey-patching with fake-timers or re-writing your clock interface... and still use your date library (native or custom).

I propose four clock strategies: system (real time), fixed manual (advance time explicitly), and sequential (replay of a sequence of timestamps).

I also benchmarked slightly better performances than jest / sinon.

The project is still young, so the API may still receive refinements as real usage appears.

I would be happy to hear feedback on this ! Take care.

You can check it out on GitHub: https://github.com/jaenyf/time-provider
