If you haven't read about it before, the term comes from the band Van Halen, who demanded that there were no brown M&M's backstage. People thought it was just a crazy rock star thing, but David Lee Roth later explained that it had a purpose:
Van Halen was the first band to take huge productions into tertiary, third-level markets. We’d pull up with nine 18-wheeler trucks, full of gear, where the standard was three trucks, max. And there were many, many technical errors—whether it was the girders couldn’t support the weight, or the flooring would sink in, or the doors weren’t big enough to move the gear through.
… So just as a little test, in the technical aspect of the rider, it would say, “Article 148: There will be 15 amperage voltage sockets at 20-foot spaces, evenly, providing 19 amperes … ” This kind of thing. And article number 126, in the middle of nowhere, was, “There will be no brown M&M’s in the backstage area, upon pain of forfeiture of the show, with full compensation.”
So, when I would walk backstage, if I saw a brown M&M in that bowl … well, line-check the entire production. Guaranteed you’re going to arrive at a technical error. They didn’t read the contract. Guaranteed you’d run into a problem. Sometimes it would threaten to just destroy the whole show. Something like, literally, life-threatening.
My Brown M&M atm is AI-generated comments like this (first comment is referencing something like df = ... that they removed from the code, but left the comment, second comment is super useless):
# Assuming df is your DataFrame
# Show the plot
plt.show()
That probably means whoever I got the code from just copy/pasted whatever the LLM spit out, and didn't actually think about the code at all.
What is a small detail that you pay attention to because it means there's bigger issues to watch out for?
The first thing that came to my mind was car repair.
This one wasn't one purpose. I went to a shop for an oil change and 10,000 point inspection or whatever they called it. I knew one of my headlight bulbs went out a week before, but when I got the inspection report, it said everything was fine. I went to the shop manager and asked him to confirm that the mechanic had checked everything on the report. I didn't blame him for the oversight, but he was kind of a dick when I pointed it out and had him do everything again until they found the problem.
Also, my dad always wrote the date on his air filters when he put them in because mechanics would often keep a dirty one laying around just to show it to customers and tell them that it was their filter and it needed replaced. He always got a kick out of calling them out on that kind of bullshit.
I'm one who does all the basic maintenance on my car, so if I had someone push a filter at me saying it needed replacing my response would be I didn't ask for them to remove it and I change my own filters. Then I'd demand they put it back in with me watching, because it's probably not out of my car and it's going to be very awkward when there's a filter still in there.
Got to always find a shop that you can trust, random ones will eventually screw you even in small ways. I've caught missing lugnuts and 50 psi on a tire, and from a dealership for recall work they forgot to reconnect something and it was running terribly. On the flip side the guy I know has called me on the phone and explained exactly what he found and a range of options and prices and recommendations. It's no wonder I return for his business when I need it, I don't have to worry about being ripped off. (I do still check behind, can't help the OCD when it comes to the car lol)
this happened this weekend, I had my transmission fluid changed at 125k miles, went in for oil this weekend at 134k, told me my trans fluid was "dirty and low". I use the Drivvo app and showed him I did trans fluid when I got new tires, wtf are you talking about.
Partner and I once test drove a car that had "passed" a something something-point inspection at the dealer. As partner turns onto the highway he realizes it doesn't have a rear-view mirror. We were not impressed with that dealership. (Partner later said that when he got in he made sure the mirrors were adjusted, but his brain didn't clock that there wasn't a rear-view mirror until he had to use it. TBF, the missing mirror wasn't pointed the wrong way.)
Same dealership tried to badmouth my Prius in order to get it as a trade-in. Partner had introduced me as his roommate and driver, which made it even weirder.
I always used check the spare tire pressure and note of it was low. Nobody's going to question your thoroughness if you're checking the spare tire.
"this MF checked my spare, I'm not questioning whether he put washer fluid. you can if you want."
