The contrail was blue because of Rayleigh scattering. Same reason the sky is blue. The white spiral was going too fast for an "atmospheric anomaly" because it was outside the atmosphere.
Oh right. I suspect feder thought about it in the same terms as me there. What he meant that it is a drive that does not seem to conserve momentum (I haven't read the article, but I take it it might actually conserve it).
However, a gyroscope conserves momentum, but it also does not impart any linear momentum on anything.
Hint: People knew the world was round two thousand years ago, and they didn't forget about it by the time of Columbus. Everybody with a clue knew the Earth was round. They mocked Columbus because he got his calculations all wrong and thought the way around the Earth was much shorter than it actually was. And they were right, he was totally off. He'd have died if there hadn't been a continent in his way to save his stupid ass.
Using gyros to change attitude of spacecraft is reactionless
It is not. The spacecraft is rotated one way, and as a reaction the gyro is rotated the other way.
If you have to put something into a system (like, say, electricity) to get something out (like, say, motive force), then that's not against the laws of physics, or even remotely technically difficult.
It doesn't matter how much you put into a system, you still have to balance momentum, or you're breaking very fundamental laws. You can not create momentum in one direction without also creating an equal momentum in the opposite direction.
The usual Windows scenario is more akin to the lock not keeping the thief out.
No, the usual Windows scenario is exactly the same as this Linux scenario. The argument wasn't that Linux is particularly insecure, it was that Linux is just as vulnerable as Windows, which is largely true.
We are not. The whole point is that there is one actual human user, and thus there is zero difference if the malware can spread to other users or not, since it has already infected 100% of the available users.

Good old free market, always making things better for the consumer!
So basically, you're saying Linux isn't for developers?
Well, that one again doesn't give you linear momentum.
But yeah, you can get linear momentum too if you have something to push on, like a magnetic field around a planet.

Energy and momentum are different things. Each has to be conserved separately.
No?
I can imagine the advantage is that this propulsion system means that you don't loose any mass while gaining acceleration.
That is also the case with throwing photons out the back of your rocket.

"Work" isn't the problem, momentum is. You have to satisfy both conservation of energy and conservation of momentum.

This particular attack cuts right through that, as it relies on somebody downloading and installing a package, which will not run as the Firefox user.

No, the usual Windows scenario is exactly the same as this Linux scenario. The argument wasn't that Linux is particularly insecure, it was that Linux is just as vulnerable as Windows, which is largely true.
And that means your third-party ecosystem will stagnate.
We are not. The whole point is that there is one actual human user, and thus there is zero difference if the malware can spread to other users or not, since it has already infected 100% of the available users.
And thus you raise the threshold for entry for new third-party software.
And how many desktop Linux machines even have more than one user?
Threaded view is not conversation view.
It was a friendly jab at the fact that the US is a bit behind in mobile phone technology, but you seem to be taking it awfully hard.
This is a study from Scandinavia, not from the technologically backwards US.
Yes, thank you for explaining why the tool is bad.
