A truck driver decided to park in a no parking zone. Thankfully the restaurant had gone out of business 2 weeks before.

The last thing I remember about him was this thread where he said he was suffering from testicular and skin cancers: https://arstechnica.com/civis/viewtopic.php?f=23&t=1118045&start=40

A bit of digging, he's still alive and enjoys his tesla coils, books on nuclear engineering and confederate flags.

e: and cars.

I think from my attempts to translate this, it's a pothole that they put a camera next to so they could highlight how bad poo poo was getting.

Let's talk SCUBA rebreathers! The Everest thread went on a bit of a SCUBA derail, and I figured it'd fit here, too.

SCUBA diving is mostly safe, *so long as you do open water diving on basic, well tested kit, with a buddy & backups*. But there is a particular discipline of risk-takers called "technical divers" who will do all sorts; cave diving (that's a nope from me), decompression diving (where if you go up to the surface too soon your joints swell up with nitrogen and you end up dead or with joint pain for the rest of your life) or rebreather diving (where, instead of carrying tanks of breathing gas, you carry a 'scrubber' that removes CO2 and a much smaller tank of O2 that can be injected to make up the gas volume again).

Rebreathers in particular will kill you without warning, if the tiniest little thing goes wrong. Too much O2 in your mix? Oxygen toxicity, you seize and die. CO2 scrubbing fail? "the user will experience extreme respiratory distress, followed by loss of consciousness and death".

And of course, these are all controlled by computers.

As long as you can prove that the parts and metal aren't stolen, Mn will let you title that as-is. They're supposed to inspect it to make sure you have all of the required safety equipment but they don't. If you check out the forums where people built kit cars they all have threads of people helping each other through the bureaucracy of getting the car titled but if there's a Minnesota thread it's basically just this video in the replies

No idea. Yea there was a nasty hole in the tread itself but no sign of what caused it. I did check the body of the car for bullet holes though haha. I assume she ran over a short chunk of rebar of something similar and it wedged itself just right to go through the wheel.

Whatever was inside .... it's on the loose now!

Yes. I also want to know what happens if you hit a waxoil soaked series landrover chassis with it.

I'll let you know in a couple of weeks. These are 1064nm fibre lasers, The ones specifically for rust cleaning are between 500W and 2kW. Mine is 1kW. I have some OD7+ glasses to protect myself, which for CE marked were <$200. I also have some thrown in by the laser seller, but not too trusting of their quality.

laser chat: a ~1kw fibre laser in a rust cleaning setup similar to this will heat the surface to 500-600 C. the photothermal effect will ablate any oxide layer, oil films, garbage juice etc present. source: me, the laser haver. (and "Effect of laser surface cleaning of corroded 304L stainless steel on microstructure and mechanical properties", HJ Yoo et al, 2022)

confirm or deny: safety squints totally safe with derusting lasers?

A pop or click noise emanating from the eyeball may be the only indication that retinal damage has occurred, i.e. the retina was heated to over 100 °C (212 °F) resulting in localized explosive boiling accompanied by the immediate creation of a permanent blind spot.

Seems fine to me.
