    DHH Retweeted Derek Shoemaker

    Great example of why you shouldn’t use abbreviations in code. Especially ones that can be so easily mistaken for another meaning! /universal and /device would have been clearer and hardly any more typing.https://twitter.com/derekshoedev/status/1086004172632309761 …

    Today I learned: `/usr` stands for “universal system resources” not “user” `/dev` stands for “device” not “development” Had no idea.

        /dev is clearly where all of the bugs come from. Should we sudo rm -rf /dev?

        You may want to take a look at this https://www.bell-labs.com/usr/dmr/www/notes.html … "there is a directory "/usr" which contains all user's directories, and which is stored on a relatively large, but slow moving head disk, while the of the files are on the fast but small fixed-head disk."

        I just love the efficiency of “src” over “source” as a frontend engineer, I have been able to write a few books with the time savings

        /usr was originally the user directory. They just messed up the convention afair.

        It doesn't stand for "universal system resources". It used to hold user home directories, but then some ancient Unix became too large for a single floppy, so some programs were moved from /bin to /usr/bin on a second floppy, and after that chaos, Linux and others started /home.

        Your brand new Ubuntu 18.10 has /bin and /usr/bin cause one specific system in 1971-1973 ran out of disk space on one of these 2.5MB fixed disk drives. (This is the drive cartridge that goes into the RK05) pic.twitter.com/413e9aBcwt

        It wasn't about the typing. It was about the number of words that the PDP 11 could hold.
