I think this is false thinking. The 737 is by now a very well tested airframe. Yes, you change some things and there are unexpected results, but the core is sound. Starting over on a completely new design, everything has to be debugged from

Yeah, as far as I understand, there's nothing preventing you and me just trading the same money back and forth at ever increasing speed, creating economic "growth" without physical limits.

Maybe space should be defined as the altitude you need to have to not have your orbit decay in less than one orbit. I wonder what altitude that is, actually.

Sure you can contract out the work, but paying for someone else to make a rocket you launch doesn't really qualify you to say that you did anything. It also doesn't teach you anything, so what's the point? Most of what you

You can't make movies with them though... It would make an expensive camera. ;-)

So would you please post the data on your devices here on HN, since you think we are all collectively owners of it? How about we start with your location and search history.

How about the POV that if I buy the device, I decide what the device does? This is a fundamental property right. You may argue that the data created isn't "mine", but I would argue that it is absolutely my data if it is c

Under the radar. No, literally by the radar... I'm confused what you mean. Surely it's not news to a pilot that ATC facilities save radar data. For how long is a different question.

There's an existing solution to that: the "range hood".

With a 6000 sf house, surely you have enough space to have both open and closed off parts of the house?

"The closed floor plan, especially the closed kitchen, can help save energy by the simple principle of not heating and cooling rooms that are not currently in use, as well as by isolating rooms we want to keep warm or cool." This

On the other hand, if you have a choice of whether to do it according to code or not, wouldn't you rather pick the one that's legal? Or, if you judge it not worth it, at least be aware of it?

Indeed, and I'm surprised it wouldn't be. When I was a graduate student we got tuition waivers but beyond that it was a salary for being a teaching or research assistant. TAs were definitely considered employees, because they were

ILS is ancient . "Tests of the ILS system began in 1929 in the United States." It's really just a radio beam. It's no wonder it can be mucked with.

That's exactly the point. It's not that playgrounds should be more dangerous for the heck of it, or just because kids think it's more fun that way. It's because learning to deal with danger is an essential life skill a

I remember being in Japan and seeing these "all walk" signals, including crosswalks that went diagonally through the intersections. Brilliant.

I was almost hit when jogging through a crosswalk from this, but I saw the driver was looking left as he came rolling through the stop sign ... in his police cruiser.

Astronomers don't really use UTC for pointing telescopes though, they use sidereal time. A sidereal day is 4 minutes different from a mean solar (UTC) day, so you still have to do a conversion. You still need something that keeps tra
531.
by lutorm 7y ago
Yes. Leap seconds are there to align UTC (an atomic time) with UT1, which is defined based on mean solar time, ie "the day", since UT1 isn't uniform. Without leap seconds, UTC will slowly drift out of sync with the Earth&#x27

It's a lot easier to test and prepare for something that occurs at least semi-regularly than a monumental event far into the future that is "so far into the future we don't have to worry about it"....

I didn't realize people knew about liquid oxygen 8000 years ago.

Powertrain components are required by EPA to have a 10yr/100k miles warranty, I thought? So it's not exactly the same situation because fundamental parts of the powertrain are covered by a longer warranty.

Sorry for making unclear references. My question was referring to "it is [lift], not thrust, that creates the problem MCAS was intended to fix", which I never addressed before. The article you linked has some nice cross-sectional

And today there are only 2 flying B-29's left. (Until recently, there was only one.) https://youtu.be/ncUdqT8AxY0?t=261

The key points are that the engines do produce lift at high AofA, and it is this, not thrust, that creates the problem MCAS was intended to fix. Is that really true? I agree that the pitch-up torque from engine thrust does not vary based

Isn't that exactly what I said? Edit: not quite, good point about center of drag in steady state conditions.

While that's why the system exists, in this case we're not near a stall, we're just bringing the nose down because the system erroneously thinks we're near a stall.

Well, I'm sure they'd prefer being upset over being dead... although the likelihood of successfully rolling over and flying a negative-g recovery in a transport airplane seem dubious at best. Transport category airplanes are only
