Ctrl-C Profiling: A Simple Debugging Technique for Lazy Developers

I admit that I sneered at the idea at the time, because, despite those comments' almost aggressive enthusiasm, this method doesn't actually work on the hard problems.

But as my outlook on life worsened with age, I came to think that Ctrl-C profiling deserves a shout-out, because it's very effective against stupid problems encountered by lazy people operating in unfriendly environments.

you don't need profilers - just Ctrl-C your program in a debugger instead, and you'll see the call stack where your program probably spends most of its time.
