I once had a university project where we were implementing low-level threading for a custom OS, and had some task manipulating the signal handlers. Needless to say, we ran in to a few issues with the code we wrote. At that time, I was pretty much a print-line debugger (still mostly am). I failed that assignment, but in the process learned how to use gdb.
