The Missing Semester of Your CS Education
https://missing.csail.mit.edu/past/ ↗Their other posts in the index, biggest breakout first.
If you're a CS major that wants to level up this winter break, you want to check out this MIT course. It's called the missing semester of your CS degree and there's eight lessons that go over basic things that you absolutely should know as a software developer. It goes over using the command line, get, vim, debug and even more. To be completely honest, looking at the lectures and what's covered. Most of this is going to be way more useful for personal projects and your upcoming internship than most of the classes you're taking in school. You can check out the past lectures for this class at this URL or you can wait for the 2026 lectures to come out on January 12th. I personally wish I knew about this sooner. What's one thing in CS you wish you knew sooner.
