For me it is not recording credentials with the assumption I would simply remember them later, while having every opportunity to archive them before eventually forgetting. Also, not keeping detailed enough notes & photos of exactly how my hardware is attached.

    I installed Ubuntu back when that was popular, and insisted on having all the graphical bling, like 3d cube that would spin to change desktops. And windows that shook like jello when you moved them.

    Of course all this messing around by an amateur did nothing for stability and after 3 or 4 frustrating issues I went back to Windows.

      I can’t even function without the Compiz 3D cube anymore, it makes it super easy and visually intuitive to switch desktops. Very handy for someone running 4 virtual machines simultaneously…

          Sure, some of the effects are basically useless eye candy, but the 3D Cube thing is a non-intrusive, yet very intuitive way of switching desktops. The 3D Cube doesn’t even activate until you use a hotkey combination plus the mouse. It’s almost like having a virtual KVM switch if you’re running virtual machines.

          To each their own, but you might actually like the 3D Cube and possibly some other Compiz features once you see how they work and what they offer…

    I don’t think I’ve ever lost more time than I’ve gained in knowledge from the mistakes, if that makes any sense.

    Never lost any money with linux.

    I wasted a few hours, trying to make some flatpak apps do as I wanted, before I understood how flatpaks works, and why they are not always a good solution.

    When installing arch, I wanted to kill my old drive. So 2 times in a row, I forgot to look up my drives Name, and proceeded to wipe my USB stick with /dev/random. 2 times.

    I’m actually amazed I haven’t had any costly mistakes yet considering I’m the kind of person to say “it’s just dd, what’s the worst that can happen? it’ll be fine no worries”. Since I’ve installed Arch a year ago I’ve been constantly expecting to catastrophically break something… and my system is still running, somehow. It’s very perplexing.

        Right… sure… erm… of course I do, obviously 😅

        Actually I always mean to do it but I keep forgetting… Recently I’ve resigned myself to the fact that I’ll never remembering to do it so I’ve been trying to set up an auto-sync to my NAS with rsync and inotifywait so I won’t have to ever think about backups again… But I really suck at coding so it’s not going too well 😅

    Bluetooth didn’t work on my laptop. Got new bluetooth card (exact same type). Bluetooth still didn’t work.

    Turns out:

    1. The specific card doesn’t support Linux.
    2. My laptop has a hardware whitelist in the BIOS that prevents me from installing any other card.
    3. My headphones don’t support USB bluetooth.

        Me, finding out this exists after buying a used sff HP pc and wondering why it won’t display out to any new monitor unless I unplug and plug the power cord: 💀

        Luckily (or not so luckily), I was able to turn off the HP “security feature” from the bios. The pc came from a former school fleet of sff pcs

    One time I’ve lost around 200gb of data, by accidentally removing a folder, instead of its symlink. Didn’t have backups either, but it wasn’t anything I couldn’t get again

    Not Linux, but OpenBSD. I got a sun ultra 5 for free so I decided to make a router out of it. After some research OpenBSD looked like the best option. I bought a pf book and started writing configs. After about a week I had a really nice router that did exactly what I asked it. This was back in the early days of xbox360 so getting all of the port forwarding right was kind of a pain since we had three of them connected in our apartment along with all of the computers. Then the harddrive crashed and I hadn’t made any backups. That was a lot of work down the drain.

    Not costly in anything but time, but I tried to crossgrade an i386 server to x86_64. Eventually it got broken enough that I restored from a backup and just rebuilt a new server from scratch in a VM to replace it.

    I installed some library from sources on my working laptop, and it stopped booting lol. Had to change my laptop for the newer Thinkpad, because you cannot insert into working devices any flash drives to boot from and fix the system. It hasn’t cost me anything, but was pretty funny

      Now you know why it’s called the Disk Destroyer.

      Before using dd, I prefer to run lsblk first so that I can see what each disk is called. Before pressing enter, I also double check the names with the lsblk output.

      i love the raspberry pi imager for that reason. i don’t want no balena etcher stealing my data, but a gui is very convenient for flashing isos, so raspi imager it is! (works for any iso you want)
