I've built a p2p file transfer program [0]. All my development experience had been in Python, but I really wanted to try a statically typed, low level language, and decided to give rust a try.

It was hard to get going, and I still only know basics, but everything just works! Typing, borrow checker, the matched results, all of that makes code bullet proof.
