The AI-generated cat pictures thread
FWIW, Marc Gene is a Ferrari factory test driver. I believe this car is a a factory-owned car that they bring to certain Clienti days for demonstration laps. He also holds the unofficial record at Laguna Seca (1:05 something). (skip to 1:35 for the actual lap -- they turn off the stupid music for that)

Nah, ball bearing or marble from a slingshot (that's what windows looked like after I'd done this as a kid to an abandoned house when the window didn't shatter and the marble/ball-bearing just bounced off).

The 'road ends in water' one is potentially quite useful at night.
Also, the mountain lion one is non-intuitive and correct. Of course, mountain lions are ambush predators, so the most likely way for it to attack you is to hide in a tree and then jump down on top of you without you ever having seen it.

Now it makes sense. From BYU Magazine:
A Not-So-Shocking Story
By Rebecca Hoffman Carlson (BS ’95), Laie, Hawaii
In 1994 the BYU Astronomical Society office sat high atop the Eyring Science Center (ESC). It was our headquarters for running the planetarium, the observation deck, and the telescope dome. The office also housed the drive for the Foucault pendulum, that brass ball that swings in the ESC Lobby.
One night, after hearing a professor complain about people playing with the pendulum, we thought up a plan to scare off troublemakers. We measured resistance in the pendulum’s swinging wire, then made a sign that read: “DANGER! DO NOT TOUCH! Wire contains 10,000 ohms!”
Well, 10,000 volts might be unpleasant, 10,000 amps a serious problem, but 10,000 ohms never hurt anyone. It only sounds scary. Snickering at our prank, we hurried downstairs and posted the sign, then retreated to the balcony to watch.
Some people would read the sign then run a worried stare up the wire to the hole in the ceiling. Others would read the sign and burst out laughing. We had, unwittingly, developed a perfect geek detector!
Many years later during a visit to campus, my husband and I discovered to our delight that our joke had been immortalized. There is now a permanent plaque that reads, “CAUTION! Do not touch the pendulum ball or cable! 10,000 ohms.”

Speaking of jobs that Americans won't do...
Today, your pal Erat was into a 50hp rotary screw air compressor.
I found the following:
An old grey beard told me today that the failure in the attached image was due to "hydraulic shearing". What you see is a thermostatic valve that came out of the rotary screw air compressor(shouldn't see oil temperatures over 300f i would assume). I've seen this before(on our other machines), but never knew what it was. Anyone see or heard of this before? Google brings me all the wrong results.
What it should look like:
Also today I was a controls engineer. I wrote my very first ladder logic program. Then i spoke to my boss regarding my compensation and he gave me a bit of a pay bump for the hours i was working on it.

That is astonishing. I have never seen that kind of degradation of a valve, and I've seen some pretty fucked up and abused hydraulic machinery...
In unrelated news, listen to this on a set of reasonably high quality monitors, in a well-built mastering studio, if you happen to have access to one:
