Dunno what made me think of this just now. When I worked for IT in a school district way back in the 90s, a librarian told me she kept a supply of mouse balls in her desk because kids would steal them out of the school computers. What I remember about those balls was they picked up dust and crud off surfaces. Pretty soon optical mice came along and they were history.

    I remember doing work experience at school in the computer lab. Thought I was gonna learn fun stuff on the servers, ended up cleaning gunk from the rollers if every mouse in the entire school (And cleaning every PC out, and flashing entire labs one by one with updates OS…)

      I worked for my district’s IT department when I was in high school. I think my sophomore or junior year.

      It was pretty cool really. Mostly it was transcoding VHS tapes into MPEGs, but occasionally I got to do odd jobs around the school district.

      Once I got yelled at by a grade school secretary, and treated with suspicion even after she had called my boss at the district IT office to confirm I was indeed there to replace a graphics card on a computer.

      While she was walking me to the library or classroom or whatever she took the box from me, pointed to the 3D orc on the box, and said in the bitchiest possible tone, “So what is this? Is this supposed to be part of the curriculum?”

      I calmly said, “No ma’am, that’s just the advertising the manufacturer puts on the packaging. It’s a graphics card, it can be used to play games so they advertise that.”

      “Well kids shouldn’t be playing these kinds of games in school!”

      “It’s a graphics card. It’s how the computer displays any kind of graphics on the screen. The computer needs a new one. I don’t know why, I’m just doing what I was told.”

      Man that woman was so much of a bitch I remember that interaction better than most of high school.

    I was in highschool at this point and I totally would have ratted any kid out for that.

    No mouse balls would mean no Quake or StarCraft in the lab after school… Unacceptable!

    I only did it once, because I hated the teacher and I guess I thought that would send a message. I was immediately caught and the kid who saw me pocket it kept saying I “liked mouse balls,” so it really backfired pretty spectacularly.

    Those balls were nasty as fuck. I remember when I was like 13 and the mouse at my dad’s pc wasn’t working right. A friend recommended cleaning the ball…it was disgusting.

    Crazy to see this in my feed, I was just thinking about this the other day. I didn’t steal the balls, but I remember figuring out that I could remove them and clean the crud off of the rolling components inside to smooth my cursor movement. (This would have been 3rd or 4th grade.)

      Kids these days will never know the satisfaction of opening the bottom, removing the ball, and then taking an unfolded paperclip to remove all the built up crud and hair on the components inside. I would do this anytime I was left alone in my mom’s office while she had a meeting or something.

        Youre mom probably wondered why her mouse started working smoother.

        I always keep an old toothbrush in my pencil cup for cleaning the mouse contacts. I dont use a mouse, I’ve always used a track ball, and now and then you have to pop out the ball and clean the accumulated crud out of the contacts.

    We had to flip the mouses around at the end of every computer class so the teacher could check all the mouse balls were still there.

    By the time I hit grade school the balls were outdated. So I missed out on this. What I didnt miss out on was finding a broken (exposed) usb stick and when I would plug it into a computer it would shock me a bit and the computer would shut down. I felt like I had the ultimate power in my hands

    Yep. We took them out because we thought they would bounce (they did not). But they were hard AF so we’d just throw them at each other during recess.

    In my school, the teacher’s computer had software running to remotely control the student’s computers, lock them or see a mosaic of all the student screens to make sure they are doing what they should be doing.

    Except, the computers were all run with admin rights and you could just open the task manager, kill a couple processes, and the remove software didn’t work.

    We always said it just must have been buggy software.

    Sorry Mr. W. You were one of my favorite teachers, but that secret had to be kept a close secret between students

    For us it was putting a space in the username field of the login screen, and then moving the cursor back to the start of the field.

    The username field wouldn’t reset on a failed login attempt, only the password field did. So users would do a visual scan of the username field, confirm that’s correct, assume they miskeyed when entering their password, try again, rinse and repeat.

    That and rotating the desktop, switching the keyboard to Dvorak, etc

      That’s a good one.

      We used to screenshot desktops, set it as the wallpaper, and move all the desktop icons to a temporary folder.

      I’ve heard swapping the N and M keys is a good one because it doesn’t register as unusual on a visual scan but messes up touch typists.

        I remember the teacher calling out “I cant see your screen” constantly and for unfair reasons, on chromeOS you can (frequently on accedent) abuse the security systems made to limit the damage of rouge extensions. Mainly the “no screen sharing on chrome:// and file:// tabs pages”. I also found a glitch that got patched to run the browser part on a higher privlaged UID (possably root? somthing related to OOBE? the lock screen itself? IDK). It was unstable, dangerous for the OS itself and could go to any site you wanted, this account had a blank chrome://policy and no extensions so anything was fair game. That got patched fast tho. My small group of friends still got to keep their chrome://flags changes even after the patch.
