It's so strange that we talk about languages being slow, and have done for years. Computer performance has increased so much in this time. https://hbfs.wordpress.com/2009/11/10/is-python-slow/ (shared on HN in 2009) discusses Python being slow. My underpowered Thinkpad has 20x the single-threaded performance! https://www.cpubenchmark.net/compare/73vs3766/AMD-Athlon-64-4000+-vs-AMD-Ryzen-5-PRO-4650U Maybe *relative* performance of languages matters more?

It is *really* hard to find a good screenshot for a CLI tool when users are on a mobile browser. This is the best I've come up with so far. I'm showing the terminal GUI to show where you'd use the tool. I'm also trying several standalone screenshots to make it more comprehensible.

I've just squeezed another 5% of performance out of difftastic by finding a few HashSet values that weren't FxHashSet. I do wonder whether hash DoS resistance is a good default. Sure, Rust programs are often pretty fast anyway, but it feels like a different threat model to the rest of Rust.
