Taking the mutex uses (uncontended) atomic ops.

In general your unpinned userspace threads will hit the same CPU 99.99% of the time, but not 100%.
loeg··on Optimizing a Spin-Lock
Spinlocks are unsuitable for situations where you can be involuntarily context switched (the vast majority of userspace programs). Probably worth mentioning that.

Real architectures you'd run more than a single thread on? Such as?
loeg··on Nike exits the S&P 100 after 18 years and a $200B market-cap wipeout
Just running in general. Not only ultras.

Who cares. Everything has a lifespan.

There are tons of non-maxi shoes around still.

Hoka blew up in the running space, like, ten+ years ago. The first Cliftons were pretty novel for being extremely plush. Light-ish weight maxi shoes weren't really a thing before Hoka popularized them. Now every running shoe brand offers something in that space.

More recently I think they've been adopted by the "active retiree" crowd? They're nice to walk in.

(I owned some of the original Cliftons myself. Did not love the flimsy tongue or cheap insoles that would slide around and crumple under your toes.)

Chop is another word for the stamp.

loeg··on Global shortage has led to motor oil rationing at Costco
And in fact it is necessary for it to be imperfect, and the oil is what lubricates the interface. So it is necessarily exposed to lots of heat and pressure.
loeg··on Global shortage has led to motor oil rationing at Costco
Yeah, but the intervals are much longer.

20 qts every 7 days is far more than any home consumer needs -- this must be to prevent shops from just buying out their entire stock.

"Woke" is the 20 side of myriad 20-80 issues. It cannot accurately be described as "broadly popular."

Uh, no, those things did not arise out of terrorism.

We've already got the G7.
loeg··on NTSB issues investigative update on B-767 runway excursion accident in Miami
Left main gear finally touched down at 00:19 and they slowed from 134 to 120 knots between 00:19 and 00:15.

No buddy. I'm just saying it wasn't "capitalism," which was your claim. I don't think you can pin this on Trump or his admin, either.
loeg··on NTSB issues investigative update on B-767 runway excursion accident in Miami
Yeah, but it's also Pilot B's job to take over if Pilot A isn't flying safely. He didn't.

They were not over takeoff velocity at that point. They were at 120 knots when they initiated GA and slowed to 117 knots before aborting (again, the engines take time to spool up despite full thrust configuration and no braking over those seconds). Takeoff is at least 130 knots, I don't know for their exact configuration. (At max takeoff weight it's something like 153 knots, but at the end of their flight they aren't carrying a full fuel load.)
loeg··on NTSB issues investigative update on B-767 runway excursion accident in Miami
Yeah, to some extent. But you see a lot more of this in GA (or Part 135) than in Part 121 airline operations. This was exceedingly bad judgement by real professional pilots in a 767.

Ah, yes, the Soviets never took risks. It couldn't be that humans are fallible.
loeg··on NTSB issues investigative update on B-767 runway excursion accident in Miami
How did they ignore the descent rate and speed? They were absolutely diving at the ground. It's just such an elementary mistake.
loeg··on NTSB issues investigative update on B-767 runway excursion accident in Miami
You can go around and try again at the same airport long before you have to divert.
loeg··on NTSB issues investigative update on B-767 runway excursion accident in Miami
They were in a bad situation long before they touched the ground and should have gone around even earlier.
loeg··on NTSB issues investigative update on B-767 runway excursion accident in Miami
No, this stuff is all downstream of their terrible earlier decisions.
loeg··on NTSB issues investigative update on B-767 runway excursion accident in Miami
They didn't have much runway left at 00:15 and were far slower than 158 at that point. They came in far too fast, descending too rapidly; first touch was >50% down the runway, and they didn't get the left gear down, so the spoilers and brakes didn't apply until even later.

Should have had a better approach; should have gone around before they even touched the ground; conditional on the bad approach and first touch, they should have gone around after the initial touch 50% down the runway. But they made the wrong choices at all of those points.

loeg··on NTSB issues investigative update on B-767 runway excursion accident in Miami
The go-around decision was far too late. Remember the engines need significant time to spool up. The decision to cancel the go-around was correct (conditional on the preceding series of terrible decisions).

It's just non-responsive to the parent comment. Lay people would consider that "stolen," whether the original account holder possessed a legal right to the name or not. GP even quoted it like that to show they were not talking about the legal concept of ownership.

First time interacting with journalism? Granted, this is even more slanted than typical.
