Scientists may have finally solved the black hole information paradox
Researchers have proposed that black holes stop evaporating at the last moment, leaving behind tiny remnants that preserve all the information they contain. The same seven-dimensional geometry behind this idea could also help explain why elementary particles have mass.

Show HN: DemandMap – Memory Mapping S3 into Polars on macOS Without FUSE
Basically this exists to solve one of my biggest pain-points with dataframe libraries and big data. It's basically impossible to lazily download data on S3 with polars unless you're processing it strictly sequentially, and even then, it won't work with arrow and numpy data.This allows you to "download" a multi-gigabyte file on S3 into a Polars DataFrame in <100ms.# Demo alloc = demandmap.S3Alloc( "./cache.bin", # number of blocks
Show HN: Cona – design your real room in 3D, in the browser
Hey HN! I've been working on this idea for around 9 months and want to know your opinion on the concept and the experience.I came up with it when I moved in with my girlfriend and we had a hard time making our small studio work. In Cona, you can draw your floor plan with real dimensions, scan your room, or pick from a template, then design it with real, purchasable items. It's free and there's no sign-up to try it. I wanted to build something that helps people like me actually liv
