See if you can find some bottleneck in one of your Python/Ruby/Perl apps that's chewing a lot of CPU time. See if you can devise a definition for a relatively simple function that if it was REALLY FAST would make this hot spot a lot more efficient. Then implement that function in C and expose it to the high level language. It might not be a good idea to actually use your fast C function in production (if you're new a…
> See if you can find some bottleneck in one of your Python/Ruby/Perl apps that's chewing a lot of CPU time. I found that hard to do as a starting developer who didn't know what was actually a bottleneck in my code, but I did have a particular library/gem that I wrote myself that did a few things I constantly needed (think of authentication in a web app, it's almost always included). So I rewrite it in C. It didn't r…
That's what a profiler is for! Even experienced developers use them, it's the only reasonable way to find bottlenecks.

That works too! :)
