Bought a cheap hoistway door gauge online and it cost me a whole morning

Found one for $25 on a discount site, figured it was a steal. The thing was off by a full eighth of an inch right out of the box. I had already set three doors on a job downtown before my foreman caught it. Had to go back and reset every single one, which burned about four hours of labor. Anyone know a reliable brand for these that won't break the bank?

I spent a weekend helping with a dig using a trowel and a brush versus a full team with ground-penetrating radar. The difference was insane.

Our town spent $50k on a solar panel art piece instead of planting trees

The art piece generates maybe enough power for a few streetlights. A proper urban tree program would have cooled entire blocks, cut AC use, and absorbed way more carbon. Anyone else see public money spent on greenwashing instead of real solutions?

Found a weird trick for cleaning thermal paste off old laptop CPUs

I was working on a 2015 Dell Latitude last week and used a tiny bit of rubbing alcohol on a coffee filter, which worked way better than the cloth I usually grab, and now I'm curious if anyone else has a go-to method for that kind of gunk.

Tried a new airlock style after my old one kept getting gunked up

Switched from a basic S-shaped bubbler to a three-piece airlock for my kimchi, and the difference in how clean it stays is huge. Anyone else find one type way easier to deal with for messy ferments?

Back when I started, I spent a whole weekend trying to get my first loop to work right.

The problem was I kept getting a list index error in Python, and I couldn't figure out why my loop stopped too early. After about six hours of staring at it, I found a tip in an old forum post about using 'len(my_list) - 1'. That was the trick. It finally clicked that I was trying to reach one item past the end. Has anyone else had a simple fix like that for a loop that just wouldn't behave?
