I agree with LibreCalc and CSV, in some internationalclasses we always had issues with excel saving CSV in actually different formats depending on the machine locale. LibreCalc never had this problem.

I still remember years ago one time windows fucked itself and god knows why I couldn’t fix it even with USB recovery or stuff like that (long time ago, I don’t remember).

Since I couldn’t boot into recovery mode the easiest way to backup my stuff to a connected external drive was “open notepad from the command line -> use the GUI send to… command to send the files to the external drive -> wait and profit” lol.

Off-topic, but for someone who recently switch to hhkb layout, I find it way more comfortable to activate shortcuts with caps-lock (Ctrl in hhkb) pinky rather than with regular command.
