Yep. Foot is Wayland-only

I should add that Alacritty running with X11 compatibility isn’t quite as fast as running it on Wayland. Both Alacritty and Foot can utilize Wayland’s excellent frame timing/vsync support to prioritize rendering only when the display refreshes. Doing so reduces load (esp. in Alacritty’s case since it can offload most work to the GPU), which is sorely needed because proper font rendering is an intensive process to do in a latency-sensitive manner.

Advanced font fallback is one of the defining features of the Foot terminal, if you’re interested. You can even specify different fonts, which is useful for e.g. getting emojis to fit in one cell.

I wrote an article in a similar vein a month ago: Becoming physically immune to brute-force attacks.

Stuffing the planet into a 100%-efficient furnace isn’t enough to crack a 256-bit key.

I’m building off those ideas in what will be a little collection of programs that measures and generates passwords given physical constraints of a brute-force attacker (energy, power, mass, etc). The collection isn’t really a collection yet; it currently contains almost one complete program: https://sr.ht/~seirdy/MOAC
