## Summary

Elecia White discusses her new 'Making Embedded Systems' course on Classpert, detailing the curriculum, hardware choices like STM Discovery boards, and the challenges of designing quizzes and explaining memory management metaphors. Christopher White shares a technical deep-dive into solving concurrency issues in Python by switching from threading to multiprocessing, specifically for handling GStreamer video pipelines and CAN radar data. He also explains the difficulties of bit twiddling for signed integers in Python and demonstrates using CLIP+VQGAN generative adversarial networks to create album art for his EP '#ihateeverything'.
