You may remember this youtuber from such famous videos as "Harder Drive", "Uppestcase and Lowestcase Letters", or "30 Weird Chess Algorithms". He tends to put out videos around once a year, often about not-awful machine learning.

This time it is a video about solving a horrible high dimensional optimization problem involving convex polyhedra. As well as 100% clearing Call of Duty Black Ops: 6.
