I’m sute Matt Parker has made a video about this.
I always got eaten by the grue sadly.
oh i see.
yea, chickens are pretty cool.
No, the ?=15
The right-hand number minus the left-hand number equals the lower number: 99-72=27 Therefore 36-21=15
I love the cool shit I find at work
The sleeper hit of colas
Last night was a frigid, totally clear sky night and the northern lights forecast said low solar activity. So I pointed our IP camera north and bashed out a few scripts to record continuously and create a long-exposure star trail photo, hoping to have a really clean star trail. Yes, I have nothing better to do at night…
Turns out, we did get northern lights - and some light pillars too. So technically my clean star trail is ruined. But the image still looks cool.
At least that gave me an opportunity to make a timelapse video of the northern lights with the source images I used for the star trail, which you can see here:
Aircraft probably. The airport is 20 mi south of here and quite a few airplane routes head due north.

Really annoyed me that the kiddos voted to not switch, and they got the car. Getting children to understand that 1⁄3 is smaller than 1⁄2 is hard enough. I’m going to program my own evil version that only wins on switch the first time next time I do this.
LOL I did this too when I first heard the solution.
I was like “no, that cant be right”. Then ran the test and was surprised by the result.
The issue is that this isn’t a fraction problem, it’s a statistics problem. You need sample size. You need to teach it with M&Ms or something small, and let the kids choose to switch or not switch and play 20 rounds each with that choice, then compare piles.
Bought a secondhand laptop to take some of the wear and tear off of my daily driver, and spent the better part of the afternoon and most of the evening trying to get the sound working. Sound card was detected, the headphones worked, and it acted like sound was playing but the speakers weren’t making a peep.
Messed around with every Pipewire setting I could find, tried re-mapping the internal “pins” with some obscure JACK utility, tried several kernel flags, and went down several more rabbit holes that looked promising all to no avail.
Finally took the thing apart, and the speakers were just disconnected from the motherboard 🤦♂️ Apparently the refurbishing company forgot to re-attach them.
All in all, not bad for a $150 “beater” laptop.
I usually do that, too, but didn’t bother this time since it’s a slightly different model but uses the same motherboard as my old work-issue laptop, and I already knew everything worked in Linux except the fingerprint sensor. Only fired up the W11 install it came with to make sure it wasn’t DOA and wiped it immediately after – I just forgot to check the speakers lol.
I was joking it was a beating off computer, a beater computer.
I took the toaster apart and cleaned the contacts for the lever that signal the hold down while toasting. Now we don’t have to stand there and hold it (that was 3 morning routines slightly out of order).
I had to buy a set of special bits because someone decided they needed to use security torx bolts in the corners hidden under the feet. This was of course in addition to the 14 regular old #2 Phillips screws. But it’s always nice to have a reason to get new tools.
In other news, the clean signal started flashing on on the espresso machine today, so I have another little project for tomorrow too.
You should be proud of yourself.
Good work!
Plumbing is way, way easier than drywall (in fact I would go so far as to call the supply side of it “easy,” including soldering copper pipes); it’s just that the penalty for failure is so much higher.
I partly agree and partly don’t.
Plumbing as a field is way broader than installing drywall, and there’s a ton to learn. No single plumbing task is really harder than hanging drywall (except maybe welding), but doing all the drywall in an entire building is a hell of a lot easier than doing all the plumbing for it.
I’m only talking about DIY plumbing a single-family house, and I only said the supply side was easier. The drain side is more complicated to understand, with the slopes and venting and whatnot.
