There's something about real optimization stories that I find fascinating – particularly the detailed ones including step-by-step improvements and profiling to show how numbers got better. In some way, they are satisfying to read.

Nicholas Nethercote's "How to speed up the Rust compiler" writings[1] fall into this same category for me.

Any others?

(Author here) I'm a huge fan of the "How to speed up the Rust compiler" series! I was hoping to capture the same feeling :)

Having your last name be Ravid really is the icing on your cake.

Real is about the only other codec I see that could be a name, but nobody uses that anymore.

Do your part: name your kids "ffmpeg" and "vp-IX"!
