Zs3 – S3 server in ~1K lines of Zig, 250KB binary, zero dependencies
Most S3 usage is PUT, GET, DELETE, LIST with basic auth. This does exactly that. SigV4 auth, multipart uploads, range requests. Storage is just files on disk. No versioning, no ACLs, no encryption. Use MinIO or AWS if you need those.
In plain words
Zs3 is a lightweight S3-compatible server written in Zig that handles core operations like file upload, download, deletion, and listing with SigV4 authentication. It supports multipart uploads and range requests, storing data directly on disk. The minimal implementation spans approximately 1,000 lines of code with no external dependencies. It lacks advanced features like versioning, ACLs, and encryption, making it suitable for simple storage needs rather than complex enterprise requirements.

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
