  • Yes, actually. Example: Triglidae

    They are bottom-dwelling fish, living down to 200 m (660 ft), although they can be found in much shallower water. Most species are around 30 to 40 cm (12 to 16 in) in length. They have an unusually solid skull, and many species also possess armored plates on their bodies. Another distinctive feature is the presence of a “drumming muscle” that makes sounds by beating against the swim bladder


  • fun situations can arise when you write , instead of ; For those not in the know, in c++ the comma operator evaluates the left expression, discards the value, then evaluates the right expression and returns the value. if you now have a a situation like this

    int i = 0,
    printf("some message");
    

    i has a completely different value, since it actually uses the return value of printf instead


  • The y is dangerous to be used without u. Do not follow the advice above unless you know what you are doing. Instead, do pacman -Syu jellyfin-server

    The y option tells pacman to update its package database. In your case, your local database got out of sync with the database from the mirrors. This normal, newer versions of software are released all the time. Pacman then tried to get the latest locally known version of jellyfin from the mirrors, but they no longer have it, as a newer one replaced it.

    By updating the database, pacman becomes aware of the newer version and can request it from the mirror. But there is now a subtle problem: the new package and some installed package could require incompatible versions of some dependency. When pacman decides to update the dependecy package, the other package is broken. This is called a “partial upgrade”, which can seriously break your system if you are not careful.

    The u option upgrades all installed packages to the latest version, so the packages and their dependencies don’t get out of sync with each other.

    See Arch Wiki, System_maintenance for more explanation.
