So my friend doesn't believe me that a truly lossless compression exists, so I was just browsing around for some evidence and was wondering if anyone could post some links or something. That would be awesome. Thanks!

Just show him the test yourself. Get a WAV file. FLAC it, but keep the original. Unflac it. Use a comparison program to compare the two, or generate an MD5 of each.

exactly. I would actually recommend doing a comparison whenever you install FLAC and SHN programs on your computer. The first time I installed FLAC frontend it seemed to be operating ok when it was actually not (see below thread). Reinstalling solved the problem.

Doesn't believe in any lossless compression or just for audio?
I mean tar, arc, rar and zip are perfect examples of lossless compression that's been around for a long while now. Lossless image compression has been used for ages as well.
Here's some general information on compression in general.
