Show HN: Pointwise – Self-hosted Lidar annotation for AV teams
Built this because annotation teams working on serious AV/robotics datasets often can't send data to a third-party cloud, and existing self-hosted options have no real multi-user workflow.
Runs on Docker + PostgreSQL. WebGL renderer handles 1M+ points at 60fps in the browser. Full annotator/reviewer/admin roles with a review pipeline, issue tracking, and audit trails. Supports local filesystem or S3-compatible storage.
Happy to answer questions about the rendering approach or the multi-user architecture.

Ask HN: Missing page from Practical Computing magazine (1980)
Perusing out of pure curiosity the May 1980 edition Practical Computing. I came upon a rather intriguing short story "And there was light" by a certain John Abbatt, which I was happily absorbed in until, without warning, pages 73 and 74 were nowhere to be found.
I understand that finding an excerpt nearly half a century old, from a little-known magazine and a little-known author, is bound to be challenging.

Show HN: SsrJSON: faster than the fastest Python JSON library
I developed a Python JSON library, ssrJSON, built on the yyjson codebase and SIMD techniques. It can serve as a compatible replacement for most common JSON use cases, and benchmarks show it outperforms orjson, which advertises itself as the fastest. Compared with other Python JSON libraries, ssrJSON addresses UTF-8 cache related performance pitfalls, giving it a significant advantage when handling strings; technical details are available on my blog: https://en.chr.fan/2026/01/07/python-json/. In addition, for floating‑point handling ssrJSON uses the latest zmij algorithm.
I noticed that orjson has closed its issue tracker: https://news.ycombinator.com/item?id=47022606. If the community wishes to maintain a stable, high‑performance JSON parser, ssrJSON could be considered as an alternative.
