I do run into them even though I use Rust for ~3 years now, but only in non-obvious cases, e. g. when all references to the borrowed data are dropped before the end of the function.
I think this should be added to the pinned post. The current wording is a bit misleading:
Because of how Lemmy is built, everything posted on lemm.ee will still be accessible from other instances, even after we go offline.

You could also try micro, which is a terminal text editor with mouse support, syntax highlighting and many more features that you know from GUI text editors.
Gnome Shell Extensions are powerful because they are allowed to hook into everything the gnome-shell process does. If the extension API would be changed so they couldn't crash our shell session, extensions would become way less powerful and be mostly useless.
Nevertheless, it would be great if Gnome Shell could keep/recover your application state after restarting (like KWin).
I think it would be very interesting to convert e.g. a regular Fedora installation into a (so-called “immutable”) Fedora Silverblue installation or vice-versa.
As others mentioned, running a minecraft server by itself is pretty easy. If you want additional features like a Web UI, multiple servers at the same time etc. you might take a look at Crafty Controller.
Python too.
