  • Almost everything about it needs to be optional because sometimes USB is used to charge some cheap battery powered thing and sometimes it’s used to make a backup of a harddrive and sometimes it’s charging my laptop with enough power for it to be rendering video but still have a net charge increase to the battery while also providing Ethernet, video output, and keyboard/mouse input over the same one port.

    EDIT to make it more clear why the variability of USB standards is what it is, compare a modern laptop to one from 10 years ago.

    The older laptop has:

    • for video, an HDMI port (or the less common mini HDMI port), and perhaps a mini DP port
    • an Ethernet port
    • a charging plug
    • possibly some FireWire ports (may or may not be the same as the mini DP port)
    • USB A ports for keyboard/mouse and other random devices

    The newer laptop has:

    • USBC ports that can do all of the above

    The perhiperals, however, don’t support all of the features. They only support the features they actually use. As long as the laptop supports all of the optional features, you don’t need to worry about it.

    The is especially helpful for less technical users who may not want to know what the difference between HDMI and DisplayPort is. With a fully USBC based laptop and USBC perhipals you can just plug it in and it will work.

    Of course this is all dependent on the laptop implementing all of the extra features, which is still only really true of more expensive laptops.














  • My experience was that the school provided free Windows keys for a personal computer if you needed one (they didn’t provide the computer itself) but the majority of computers I interacted with on campus (mostly in the computer lab) were Linux (some Debian variant iirc). I think the printing computers in the library were windows. I took an art class at one point and they had Macs (it was for using the Apple’s Final Cut Pro).

    We never used LibreOffice though. Everyone just uses Google Drive.




  • One Minecraft server I played on installed a program for blocking x-ray hackers (a type of hack that lets you see valuable ores through walls so you know exactly where to mine).

    The anti-xray mod worked by reporting to the user that the blocks behind a wall are a jumble of completely random blocks, preventing X-ray from revealing anything meaningful.

    This mod resulted in massive lag, because when you are mining, every time you break a block, the server now needs to report that the blocks behind it are now something different. It basically made the game unplayable.

    The server removed the mod and switched to having moderators use a different type of x-ray mod to look at the paths people mine in the ground. Those using x-ray hacks would have very suspicious looking mines, digging directly from one vein to another, resulting in erratic caves. Normal mining results in more regular patterns, like long straight lines or grids, where the strat is to reveal all blocks in an area while breaking as few as possible.

    Once moderators started banning people with suspicious mining patterns, hacking basically stopped.

    It’s possible to still hack and avoid the mods in this kind of system by making your mines deliberately look like legitimate patterns, but then the hacker is at best only slightly more efficient than a non-hacker would be.
