Reading other people’s code separates juniors from seniors. Most developers read code like a novel — and get lost. Learn to read systematically: entry points, callsites, grep before LSP, git as a navigation tool.
fork() in Linux isn’t just process copying. It’s one of the cleverest kernel mechanisms — Copy-on-Write, shared file descriptors, inherited mutexes. Find out what really happens under the hood.
Debugging like a developer means thinking, not guessing.
Most engineers debug by trial and error — that’s gambling
with production code. Learn how to form hypotheses, find
root causes, and stop chasing symptoms.
