My dad came with a windows laptop and asked me to convert a lot of jpg files to pdf on a usb stick (wtf?) he showed to me a tool on the laptop that convert files one by one ... and there is 58 jpg file.
Soooo I unpluged the usb key and pluged it into my linux laptop and ...

for f in *.JPG; do convert "$f" "pdf/$(basename "$f" .JPG).pdf"; done

My dad could not believe I had finished in 5 minutes

Linux Powaaaa !
