I don’t know if this is going to raise my geek level to 900 or what, but I’ve always been fascinated by data compression. It’s one of those things that I’m fascinated with but have never pursued for some reason. It feels like a really niche space that you’d need to focus on completely to make any progress and I’m far too entertained by the work I do every day. If you’ve got a few spare hours (days?) this publication looks intense.
