So, as I understand it, the wing is broken down in sections, each of which will use some tabulated lift and drag for that airfoil at the current velocity vector and dynamic pressure? That seems fine. But it doesn't talk about how it de

I'm not understanding the situation. When I had RSUs as an employee, those grants were voided at separation. I only got to keep the RSUs that had vested before separation (which were then just common stock and that I had paid taxes on

I find it most annoying when moving your eyes. Anyone will notice the flicker if their eyes aren't stationary since then each "flick" will end up on a different part of the retina. So, instead of a normal motion blur you see

Given that they were only authorized to fly in the "Bell X-1 supersonic corridor", I'd wager that sonic booms are fairly commonplace there. I doubt there are any residents around. https://www.afmc.af.mil/News&

I really don't care for controlling lights or whatever, but I find it very nice as a common place to monitor all the different things we have in the home: heat pump, evse, humidity in rooms, power consumption, state of lawn mower b

Even with a car's higher rolling resistance, most of the drag at cruising speed is aerodynamic, though. But a commuter train, by definition, starts and stops a lot so it makes sense that a large fraction of the energy used would be for

Although "Top-level vdevs can only be removed if the primary pool storage does not contain a top-level raidz vdev, all top-level vdevs have the same sector size, and the keys for all encrypted datasets are loaded."

Apart from just peace of mind from bitrot, I use it for the snapshotting capability which makes it super easy to do backups. You can snapshot and send the snapshots to other storage with e.g zfs-autobackup and it's trivial and you can&

Given their development pace, they really must succeed if they want their "slowly and carefully" model to be competitive.

"Dark matter" is just a description that refers to matter which interacts gravitationally but not, or at least very weakly, in other ways. It doesn't imply anything about the nature of such matter. We know that there are se

Well, it's not like people pulled it out of thin air. Both inflation and the lambda-CDM models are solutions to the GR equations, so in that sense it's perfectly justifiable to see if general relativity can explain the data. I don

But it seems that the principal objection to these counts is that birds don't necessarily die on impact but may travel quite far before succumbing to their injuries, so the counts necessarily result in an underestimate of the true effe

This approach seemed super interesting and we attempted to use it for modeling a fairly complicated fluid system (pipes, valves, tanks, etc). However, in the end the equations that fell out made the solver choke. We abandoned the effort sin

IIRC the current Starlink beams are of order 10 miles on the ground. So much narrower than you guess.

Swarm wasn't a competitor to SpaceX at the time, Swarm and Starlink wasn't aiming at the same market at all. And they didn't exactly kill Swarm. They launched Swarm satellites for a while and there was talk of integrating S

It's worth noting that cash held in a Fidelity brokerage account is handled the same way, by being "swept" into a bank account held by Fidelity at an actual bank so Fidelity can claim it's FDIC insured. I guess if Fideli

The booster is already strong enough to support itself in compression, because that's what it does during ascent and the landing burn. The entire bottom structure of a rocket (the "octaweb" for F9) is basically made to transf

Every time you throw a rock, it ends up on a trajectory that "would have orbited if the earth was a point mass". That's just not a very useful definition of "being in orbit".

My experience (being fully remote for over a decade) is that it's extremely distracting to have all discussions public. It creates a lot of noise and it's very hard for people to not get drawn into conversations that doesn't

At least on our PHEV, when you read out the battery module state with an OBDII reader, you get to know not only the current estimated capacity but also how much time it's spent at various states of charge, how much time it's spent

I mean, what choice, besides averaging, would make sense? Completely disregarding one pilots input seems worse, and averaging is what happens in a mechanically connected system. The crucial difference is that in that case the pilots can fe

Thanks for the informative post. It pretty much backs up what I've already learned. However, the "complications are beyond rare" doesn't seem to be the case for myopic people doing RLE. In particular, the risks of retina

I'm considering RLE (which apparently can at least correct spherical aberration), they apparently don't really do laser treatments on people my age (50+). However, I'm not sold on the risk vs reward proposition of surgically

It's actually impossible to focus on an image within the lens, sort of by definition. It said the display is holographic, which I guess means that it will diffract light to create the appearance of an image at infinity, while not act

That's cool and all but I'd settle for the long-promised customized contact lenses that take out the particular high-order aberrations of my eyes.

The warranty is for the lifetime of the product. If it breaks, obviously its lifetime has ended so the warranty is no longer in effect...
