If you're really worried about it you could buy an airbag.

Hopefully these go from being expensive pieces of gear that only few have to being completely normal/common-place. They are a great technological improvement but right now they are out of the budget of most of the motorcycling world (which outside of the West skews heavily towards lower incomes).

Probably the single most important thing is learning good defensive driving. Which is different than "good driving".

Lots of "good drivers" T-bone the guy who ran a red light. Defensive drivers see him barreling towards the intersection, as they check both ways despite it being green.

On a motorcycle, even if a crash is not your fault, you're still dead.

Grocery stores absolutely sell sex toys now. Wal-Mart carries them as well.

I'm no prude, but it's really weird to me.

I was in Belgrade aiport duty-free a few days ago and there was a Lelo stand in amongst the usual cosmetics. "Fly in Pleasure", definitely got a laugh out of me.

Personally I think this is a good thing.

> (rare metals in a place where nobody cares how they're harvested as opposed to the ones in North America that can't be mined due to ecological concerns)

There - that's a little more accurate.

jpgvm · a month ago
It's really not just ecological concerns and tbh the mining really isn't that big of a deal. It's entirely the processing that is the problem, ecologically sure but mostly technically. Without the Chinese machines that do the processing because yes, you guessed it they are the only country in the world that makes most of them, you end up more than 20-30% less efficient. At that point on the world market you just aren't competitive at all.

This is all assuming you can get past the NIMBYs to build the plants in the first place.

China would be stupid to stop the acceleration of its domestic development right now.

If anything I could see the Chinese government moving to blocking import of Nvidia and AMD accelerators as time goes on. They can't afford to right now but you can bet they want to.

You're in luck. Video of an MRI magnet being quenched that I posted above:

Yeah so this video shows exactly what I am talking about, the chair and other objects don't fall immediately, it takes ~15s for them to drop to the ground after the quench starts.

If you can can "log by time" then what you need is metrics, not logs.

Okay, this sounds more serious than I thought. But then, why was someone able to walk into that room with metal around their neck if it was clearly so life-threatening?

Anyway, I’m complaining as someone who personally has turned down recommended medical procedures after checking radiation cancer risk numbers and realizing the radiation risk was being downplayed. When I saw the numbers, to me the cancer risk wasn’t worth it, so I went without a solution to my health problem. Had an MRI been an option, I would have more likely said yes.

Take a look at the Google Street View link someone posted. It's pretty clear this facility -shouldn't- have been able to acquire an MRI machine in the first place.

It also elucidates how such an accident could happen, i.e they clearly don't have the trained staff and protocols necessary given the danger of an MRI machine. It's very likely the poor gentleman didn't understand the immense danger the machine poses.

They are expensive and rare for a reason IMO. Yes it would be great to have more of them but the best place for more of them is within proper hospitals and leveraging economies of scale to share technicians across a fleet of them in a well run facility.

I was wondering "why would the street view be relevant?"

Turns out, it's pretty relevant to the situation - especially how the unauthorized access was possible.

This wasn't your typical hospital MRI. This is basically your local tanning salon that somehow acquired an MRI machine.

I wasn't going to click that link but now I have and honestly - that is mildly terrifying.

I don't understand how such a dangerous machine can end up in a place that looks like that.

> most MRI scanner magnets cannot be turned off like that. For the few that can, it's going to cost >$50,000 just to refill the liquid helium, not to mention the real and opportunity costs associated with rendering the machine offline for days or weeks.

I thought these days, most MRIs did have an emergency quench button.

jpgvm · a month ago
Yeah I would say all modern MRIs do. However one misconception is that loss of field strength is instantanous, it's not. The field strength drops off over about 15s or so as the helium boils off and the magnet losses superconducting properties.

So the emergency quench is less useful than it sounds in these situations... it's very likely if an MRI is going to kill you it's going to do it fast enough for it not to be relevant.
