Super Dracos are for escape in flight too, including in and past MaxQ. But they are on Crew Dragon, not Cargo Dragon. Cargo Dragon did not carry a crew and wasn't programmed to save itself.

Most of us do have a need to transmit messages privately. Do you not make any online purchases?

Yes, but those have to use public-key encryption. I am sure of my one-time-pad encryption because it's just exclusive-OR with the data, and I am sure that my diode noise is really random and there is no way for anyone else to predict or duplicate it. I can not extend the same degree of surety to public-key encryption. The software is complex, the math is hard to understand, and it all depends on the assumption that some algorithms are difficult to reverse - which might not be true.

Most algorithms to do this use the time between keypresses, measured to very high precision so that the lower bits are chaotic. So it doesn't really matter what keys you hit, and it doesn't matter how rythmic your typing is.

The problem with FM static is that you could start receiving a station, and if you don't happen to realize you are now getting low-entropy data, that's a problem.

There are many well-characterized forms of electronic noise: thermal noise, shot noise, avalanche noise, flicker noise, all of these are easy to produce with parts that cost a few dollars.

True randomness comes from quantum mechanical phenomena. Linux /dev/random is chaotic, yes, enough to seed a software "R"NG. But we can do better and devices to do so are cheap these days.

I wouldn't trust anything but diode noise for randomness. If I had a need to transmit messages privately, I'd only trust a one-time pad.

Communism has been tried on a large scale - see Mao's Great Leap Forward.

Nope. That was a totalitarian socialist program pushing a collectivism that didn't work. Communism is a post-scarcity society and obviously scarcity was the thing Mao produced best.

Like most of the up-voted posters here, I think you're missing the point. This new service isn't a Google Code replacement or a Github competitor. It's an add-on for cloud-based hosting, so people who are hosting systems on Google App Engine or Compute Engine can keep their source there as well, with nice tools for working with the code online, managing releases and even live debugging... if there's a problem with your running app you can debug it instantly. The system snapshots the live system so it's not interrupted and then gives you an online debugger so you can examine the state, step through the code, etc.

It's a value-added feature on a paid cloud hosting service, not a place to host your latest open source project. That's what Github is for.

is stupid enough to leave the health of its citizens up to the vagaries of the profit motive? How many assets does a a nation have that are more valuable than a healthy population?

Whatever it has been used for subsequently, A113 is a classroom at Cal Arts.

I didn't actually work on GPUs very much at Pixar, the image computer I worked on was the grandfather of the SIMD image processing instructions on modern CPUs. What would become a GPU later on was a very expensive box from Silicon Graphics, I had one that cost at least a quarter Million dollars.

If they actually told us how to program their microengines, something good might come of it. But they'll probably just BSD-license a list of numbers, as others have.

I liked writing bit-slice microcode at Pixar. I really could get every last bit of power out of the hardware.

Maybe you should learn what communism is before calling anyone "commiefriend". (Which I have to say, is really repulsive. It's sort of like picking your nose over the internet.) I think you are discussing the difference between lasiez-faire ecomomics and regulated markets. Communism is a very great difference in scale from that. And it's never been tried on a national scale just as "free market" has never been tried because there are always economic biases that make it impossible. What there has been so far is socialism.

I think you're missing the fundamental economic issue that drives all of this. It's the provision of essentially infinite amounts of credit. This is done by government, not banks. Essentially all home loans come from Fannie Mae or Freddie Mac, banks and finance companies are really just front-ends for them and sell their loans to the government once financed.

Given infinite credit, any scarce but necessary resource is going to be bid to absurd values.

It is by no means being a hippie to assert that government should not distort the market for credit, and to expect that urban and suburban land values would return to more realistic rates once the distortion was removed. Too bad that lots of people have already invested in unrealistic land values. They would have to lose.

Superconductors just exclude magnetic flux. I am not getting how it matters what produces the magnetic flux - be it ferromagnetic or electromagnetic. My only Meissner effect demo used a permanent magnet.
