Applying different profile guided optimisation techniques to the rust compiler:

Good news: it's super easy to add LTO to Rust projects, and only added 60 seconds to difftastic's link time: [profile.release] lto = true Bad news: It only reduces the difftastic runtime by ~5%. At least it didn't require much wrangling to try :)

Here's a neat GitHub feature that I haven't noticed before: if you hover over Contributors, it shows you profile pictures of major contributors! This picture is from https://github.com/github/semantic. Reminds me of JS projects that generate READMEs with this visualisation.
