I’m working on a some materials for a class wherein I’ll be teaching some young, wide-eyed Windows nerds about Linux and we’re including a section we’re calling “foot guns”. Basically it’s ways you might shoot yourself in the foot while meddling with your newfound Linux powers.
I’ve got the usual forgetting the . in lines like this:
$ rm -rf ./bin
As well as a bunch of other fun stories like that one time I mounted my Linux home folder into my Windows machine, forgot I did that, then deleted a parent folder.
You know, the war stories.
Tell me yours. I wanna share your mistakes so that they can learn from them.
Fun (?) side note: somehow, my entire ${HOME}/projects folder has been deleted like… just now, and I have no idea how it happened. I may have a terrible new story to add if I figure it out.
Well, there’s a reason why Windows says “Don’t turn off your computer” during updates. I think noob-friendly Linux distros should implement a similar system, where Kernel updates are only installed on shutdown and a message is displayed telling the user not to shut down their computer. There should still be rescue mechanisms like Btrfs snapshots or a recovery system that automatically detects a broken kernel and reinstalls it.
I think it can be done even simpler - no need for a special screen, just make notification and don’t turn off while the kernel is updating.
