Individually press all the Shift, Alt and Ctrl keys.

This was back in the Windows 95 days and persisted for quite a few versions. The symptoms were that when typing you'd get accented or no characters, basically Windows thought one of the keys was held down. It happened more often than you'd think.

Early in my career (a long time ago), I was tasked with ordering replacement chargers for some laptops. I ordered several off Amazon and even though they were labeled as being what we wanted, they were apparently bootleg and were not, in fact, the correct charger. Fried a few laptops before I realized Amazon wasn’t the “Amazon” of yore selling first-party parts and I was ordering from random third party sellers. (That was all relatively new at the time. Amazon was a bookstore branching out in my head.)

In fairness, I was a programmer and not an electrical engineer. And chargers back then weren’t exactly USB-C level smart. The barrel charger fit. I just thought “Oh, what a great deal. I’ll order these and get plaudits from my boss for saving money.” It wasn’t even my money.

The other one is that when I was learning to code — I’m self-taught because everyone was back then — I used Vim and invented my own style. All my code was basically unformatted or, at best formatted consistently in a very non-standard way. That’s easy to fix nowadays where I can hit save and my code gets formatted automatically but it wasn’t so simple back then. I still feel bad for the engineer who followed me who had to fix that shit.

I wanted to install an extra hard drive in my computer, but the power supply didn't have enough connectors. I actually had a spare power supply unit, but upon testing, the 24 pin cable was too short to reach the motherboard.

I ended up using both PSUs. Only one had a power switch on it, so that was connected to the hard drives. I had to use a paperclip in the unused 24 pin connector to make it output power. The 2 PSUs had a wire running between the ground pins of a random unused connector, and they were on the same phase circuit.

The hard drive PSU had to be turned on first at the switch. Once that was on, I could press the power button to turn on the computer. I think I used it for about a year before buying enough upgrade parts to effectively replace the entire computer.

Just thought of another one. I have an old Amiga 1200 which doesn't get powered up much but I accidentally dropped it in a move. Since then it's been prone to randomly crashing. Opened it up, nothing appeared to be dislodged. Somehow discovered that if I prop it up at an angle it doesn't crash any more.

I just spent the better part of the day trying to get a "music archival tool" to work, but I wasn't able to get my Spotify account to connect.

The eventual solution I ended up with was to spin up a Windows VM, get the tool connected to my Spotify account there and copy over the config file from the Windows installation to my (Linux BTW) actual computer.

Of course, I've never really dabbled in emulation past old video game consoles, so getting a Windows VM up and running involved its own troubleshooting... The whole thing felt absurd, especially since there are so many easy ways to download music, but this was one of those times where I didn't want to let the computer best me.

Told a janitor to not unplug the equipment rack in a closet to plug in their vacuum cleaner. Why they thought that plugging in their vacuum there, rather than just using the outlet not 6 feet away outside the closet is beyond me.

Further, why that closet wasn't locked in the first place. But this was almost 30 years ago and it was another time in IT.

I spoke with the janitor and she started plugging in her vacuum in the adjacent outlet. Then I went to the director of IT and got the capitol cost approved to secure all of the networking closets in the building, which there were 6, one for each floor. Only the one floor was an issue as that closet also house a sink and drain for the janitors to use. There wasn't another place we could move the networking equipment to without laying out a lot of money.

After troubleshooting and rebuilding a pc of a customer back then 6 times , reinstalling it , changing all cables , checking every single hardware connector for damages and they were all pristine , no tools showed errors or anything.

Put the ram into another pc to check it , pc did boot fine , checked no errors , put the ram back in the other pc and pc boots , no issues , 7 day long term test no issues at all.

Idk what it was till today , don't forget I had rebuilt the pc multiple times prior the ram just worked after being in another pc , I even took it a few times out and put back to make sure that the clamps are OK and connector and it wasn't just luck nope , worked every single time afterwards.

I was working on a e-commerce site for a large furniture manufacturer. They wanted to add a new attribute to a site that dealt with the fabrics they used. This would have been somewhere near 500 individual products with their own value for this attribute. We had to get this lined up on the product csv because somebody didn't think to do it in the erp. One of my managers was set to go in and use Excel to merge the lists, but I realized he would have to do this every month until the end of time. I wrote a quick script on the site to do this anytime the product csv needed to be updated. Write once, run forever.
