An AMA with Xander Naumenko behind the Youtube channel From Scratch and some other cool projects! His Youtube channel, which recently hit 100,000 subscribers, showcases a 32-bit computer in Terraria (powered by a wiring reimplementation mod and Rust driver API) and the world's best foosball-playing robot. He worked at Tesla, contributing to Linux and low-level firmware for autopilot; Jane Street, using machine learning to predict financial market behavior; and on multiple significant parts of the UBC rocket project.
