Integration tests are best tests
Itegration tests are the most important kind of tests. You should strive for excellent integration test coverage and invest relatively little time in unit tests. I've believed this since I worked on c...

I have a theory that those of us who were raised on IRC or AIM are absolutely insufferable in Slack to those who were not, because instead of writing a three-paragraph thing, we'll break that up into 15 comments.

Until TypeScript, all Script was handwritten
Until C# all code was blurry and really hard to read, that's why all programmers needed glasses
Until Objective C, all code was pointless, random. The big innovation was having a goal with it

Last Sunday I discovered that lifetimes on #Rustlang garbage collected handles should be contravariant on their lifetime parameter. This is an open research question, but I think this opens a path to meaningful lifetimes on self-referential structs.
Check it out!

Yay! Setting the font and size again in gsettings/dconf worked to fix my tab/URL bar font issues.
All I personally have left are how slow scrolling is in chromium browser, and that they get a close button (I'm tiling, I don't want that!).
That and probably hardware acceleration...

Great post, of course; you noted a couple of Wayland font issues I've been trying to solve myself (and have been working around by disabling Wayland for chromium-based browsers in the meantime)

If you're new to foot, I would try out Ctrl+Shift+O rather than manually copying links; it instead pairs each link on screen with a letter you can hit and then it'll open in the browser.
I also suggest using foot --server and then using footclient as the default terminal; slightly faster to open.
