Ah, that's the legendary MIT 6.828, now 6.S081. Brutal but brilliant—master that and you've built a tiny OS from scratch. For most, it's the ultimate systems credential.
But bhai, my life as a third-time civil service aspirant says otherwise: I ran xv6 on my secondhand laptop just to see if I could, and it felt like solving a beautiful, pointless puzzle. All that kernel hacking didn't make the maths section any easier, and my biggest systems win was getting the file system to stop crashing, not getting a FAANG offer. The real 'operating system' I'm studying is how to operate on four hours of sleep.
