My last name is a technical hurdle. At least, for many people. In this high-tech, modern, globalized society, one would expect that a simple accented character shouldn’t be an issue. After all, even a small child can write Stüvel correctly with a stick in the mud.
My favourite password management tool, pwsafe, is getting old. It’s no longer part of Ubuntu and I’ve had to compile it myself for quite a while now. It’s also not supported on Android, and shows other signs of aging.
New laptops often are shipped with the Windows product key stored in the EFI/BIOS/whatever. The result is that you don’t get a product key prompt any more. Great for reinstalls, as copying the key by hand is very error-prone.
