NASA astronaut [Don Pettit] shared a short video from an experiment he performed on the ISS back in 2012, demonstrating the effects of sound waves on water in space. Specifically, …read more Continue reading Sound and Water Make Weird Vibes in Microgravity
The voice interface for the holodeck in Star Trek had users create objects by saying things like “create a table” and “now make it a metal table” and so forth, …read more Continue reading Make 3D Scenes With a Holodeck-Like Voice Interface
[Steve Mould] came across an interesting little phenomenon of blue flames zipping around a circular track. This led to diving down a bit of a rabbit hole about excitable mediums, …read more Continue reading Corral Some Zippy Blue Flames Into 3D Printed Troughs
[Andrej Karpathy] recently released llm.c, a project that focuses on LLM training in pure C, once again showing that working with these tools isn’t necessarily reliant on sprawling development environments. …read more Continue reading Train a GPT-2 LLM, Using Only Pure C Code
Aluminum beverage cans are used for all kinds of drinks, but when it comes to wine there are some glitches. Chief among them is the fact that canned wine occasionally …read more Continue reading Wine in Beverage Cans Had a Rotten Egg Problem, Until Now
