Converting 16-bit hexadecimal string into double value in Python 3

I want to convert 16-bit hexadecimal numbers into doubles. I actually did the reverse of this before which worked fine: import struct import wrap def double_to_hex(doublein): return hex(struct.unpack(‘<Q’, struct.pack(‘<d’, doublein))[0]) for i in modified_list: encoded_list.append(double_to_hex(i)) modified_list.clear() encoded_msg = ”.join(encoded_list).replace(‘0x’, ”) encoded_list.clear() print_command(‘encode’, encoded_message) And now I want to sort of do the reverse.

”Téléchargement” to ”Download”

I am with Ubuntu 18.04. I changed Ubuntu to be in English instead of French, but there’s still some French things. For instance, all the Download are heading to ”Téléchargements” instead of ”Downlaod”. How can I change that?

Holding down two keys simultaneously makes the second one repeat

I’m running Ubuntu 19.04 and I’ve noticed a very odd problem with the keyboard. This keyboard worked fine in another computer running Ubuntu 18.04, so I’m not sure if it’s a hardware or software problem. If I hold down any key on the keyboard, any other key I press simultaneously will repeat immediately. That is, […]
