At high latitudes, it doesn't get light until so late that you will reasonably never wake up in daylight in the winter. But moving the light later would make it more likely that you can get out and actually see some light as opposed to

this is just a case of the voting public getting exactly what they voted for Except that the majority of them didn't, of course...

Isn't that the point though -- that the issuer of currency should manage the system? It should simply be part of the currency just like physical cash is.

Exactly. It was obviously not "good enough", so they failed to meet that standard. That's my point.
365.
by lutorm 7y ago
Isn't the common meaning of "good enough" "sufficiently good to meet my requirements, even though I can imagine it being even better"? But you're right, I'm clearly not talking about the same thing as that

We recently installed two Curbs (energycurb.com) in our house and it's not only been very educating but also made it possible to zero in on the largest consumers. Upgrading the water heater to a heat pump unit took us from barely break

As an engineer, I sort of disagree with this. Doing a shoddy job and trying to get away with it is inexcusable, but "good enough" is the gold standard in engineering. No one is helped by spending development time and money by maki

Since autopilots on airplanes literally fly straight lines between waypoints, it's pretty clear that whatever it means in airplane contexts has zero bearing on what it means in a car context. Having an airplane autopilot fly in proximi

It doesn't sound exactly like what you have in mind, but we have a DFIUA program ("Don't Fuck It Up Again..." ;-) where people do postmortems on serious misses and report it out to the software team.

Paper airplanes usually have flat wings and they fly fine, no need to suspect.

The third law could explain lift, but it does not explain why the pressure differential would exist, and thus cannot account for the extra lift due to that. There is no "extra lift" due to the pressure differential. The pressure

A flat plate generates lift, though, so the curvature is incidental.

It may appear trivial, but thinking about it like a bunch of bullets bouncing off the wing on the bottom (the "particle regime") does not explain why it deflects air (the "fluid regime"). A fluid is governed by fundame

Sure, that has to be true if the helicopter can hover. But how do you know that's possible? You can't postulate that something flies as part of an explanation why it can fly...

Sure, that's just momentum conservation. But how do you know how much downward momentum the column of air has?

The best intuitive discussion about lift that I've come across is John Denker's "See How It Flies": https://www.av8n.com/how/ The key ingredients that I took away from the above are that circulation

Indeed, knowing what it is that is important to you may be the most important feature of your philosophy of life, and discerning this is difficult. But all we can do is try our best to figure it out and realize that time is not wasted if it

ion thruster, star trackers, phased array antennas, reaction wheels, torque rods, solar panels... they pretty much do everything every other satellite does.

It appears Aerospace Corp is calculating a 10% collision probability now...

That might be easier said than done, though, because there may not be enough space to do that. If you have the airspace packed at 2nm and then you need to revert to 5nm, all the planes will fill 2.5x as much area. Plus, how would ATC safely

I was under the impression that one of the main drivers of ADS-B is to enable smaller separation between aircraft due to the more accurate position reporting. If that's the case, then radar won't be a useful backup because planes

Except that is also the same airspace where ATC doesn't have to see you. You don't even need a transponder to fly in those areas.

What I'm struck with reading this post, and the comments, is that all we know is how our own brain works. None of us can share the thoughts and experiences of someone else. As far as I know, my brain is "normal" (whatever tha

Length-wise, our car seat only fits in the center of the back seat of our 3rd gen, and even then we have to push the front passenger seat so far forward that you have to be pretty small to fit in it. We could probably raise the seat a bit m

Partly this was because it was a joint SpaceX/NASA webcast and while SpaceX normally uses metric, NASA does not.

The Superdracos are powerful engines but they don't have anything near the delta-v to always return to land after an abort even if you fill the entire Dragon with propellant. So you'd always need the chutes anyway. One additional

The system is designed to be able to abort from a deflagrating rocket without warning (although that was not the design of today's test, obviously). Today, Dragon was already well clear when the stage disintegrated 11s after the abort.

Because you also said "... or they will let it be as is which would be unsafe?" I think your reception here would be better if you dropped the attitude and recognized that your comment used pure speculation to imply that the out

I'm not sure what argument you're trying to make, on the one hand you say the explosion looked like a controlled detonation, on the other that it seems unplanned. Like others have pointed out: as far as F9 was concerned, the test
