You might want to confirm that it is indeed zypper packages before you rearrange too much: Disk Usage Analysis on the desktop, or du -sch * on the console will get you some numbers by directory. It could also be cached packages, clean them up with zypper clean --all.

I’m not sure about specifying different destination directories with zypper, but you could try installing something like vscode from Flatpak rather than zypper, and specifying --user so it goes into your home directory (if that’s a different partition).

I’d also look at your containers with podman and clean up any old ones, they can take up a lot of space.

That’s a fair criticism around relying on implicit type conversion mechanics, and part of the tradeoff to make. On the other hand, I imagine (and my imagination may be limited) that one downside of static_assert is to increase verbosity, something like:

auto r = f();
static_assert(std::is_same_v<decltype(r),MyReturnType>> || !is_expensive_conversion_v<MyReturnType>);
return r;

I have Ubuntu 22.04 on a Dell XPS Plus 13 with OLED display. Looks great, battery life is good. Not sure how tuned the drivers are etc but definitely no need to avoid.

Welcome to C! Tiny suggestion to add to other comments: value is already Boolean, so there’s no need to write if (value == 1), you can just write if (value). Similarly, following @chamaeleon@kbin.social’s suggestion of using the ternary operator, you can write return value ? "Yes" : "No";.
