Language levels problems with Rust while learning day 1
I started learning Rust recently as on of the other maintainers of Drogon tries and likes it. And C++ have it's own pile of problems. Not saying I don't like C++ anymore just that I'm trying to learn something new. In the process I found a few places I dislike about Rust. Especially from the point of view of a HPC programmer.

Salvaging 18650 cells from laptop batteries
Lithium is a precious resource so it interests me and friends at la Bidouille to find ways to reuse dead laptops batteries. In particular I brought a laptop that got killed by spilling coffee on it back in 2014 even though it was only a few months old — absolutely un-solarpunk, I know, but at least it's fun to disassemble it completely and research how to reuse its parts.

Our hackerspace had to move out of our place and we've been without a neat place to undermine our electrical safety for some weeks now, so I'm publishing this note even though the cells have been resting in a box instead of being used for something. I would like to try salvaging laptop speakers to make a portable speaker using one of those cells, and maybe a solar lamp. Stay tuned!
