Note that the Falcon 9 first stage is not travelling at orbital velocity, or even that near it really. At separation time -- when it starts to slow down to re-enter -- "[f]or a reusable Falcon 9, [speed] is around Mach 6, depending on

Interestingly, now that SpaceX has the X-37 contract, there is the possibility of launching and recovering a re-used first stage and payload, but not the second stage! I guess this almost happened with the Dragon that contained a re-use

Well, there's always the 74181, a 4 bit ALU[0] as used in the Alto[1] among others like the NOVA and VAX 11/780. 0. https://mil.ufl.edu/4712/docs/74LS181.pdf 1. https://en.wikipedia.org/w

The Alto was introduced in 1973, but was still available in the early 80s, so there is every possibility that someone wrote a Mandelbrot generator on it since it was discovered in 1980. However it is more likely that this happened on the Xe

That's interesting, I assumed it was a solely US belief, and certainly there have been plenty of scare-story emails circulating there regarding NHS and ACA. Obviously NICE [0] (National Institute for Health and Care Excellence) does m

It sort of does hold for current cars. Generally a driver (in most cases, a human) must obtain a further license or some form of government permission/authorization to drive a vehicle for commercial purposes like a taxi or other pass

Would these be the same graffiti artists that are currently maliciously painting over road warning and direction signs to fool human drivers? Say, whiting out a 'low bridge ahead' sign, so that trucks and double-decker buses cras

So, you're actually saying something like P(N_l = L | N_f = F) or P(N_f = F | N_l = L) is (for those sub-populations) high, while P(N_l = L, N_f = F) is still globally not common. That makes more sense, but is a different statement - t

Not really that much less gravity, certainly not enough to notice, let alone have a difference to a rocket launch. Gravity varies as 1/R^2 where R in this case is distance from the earth, so it's the difference between that at ~63

Maybe, but in general in the West it isn't a problem to let a 7 year old walk to school on their own. In fact, the few cases where someone makes an issue out of it are so rare they actually make national or even international news!

So, it would seem reasonable to assume that around ~120 people/entities have caved in to the ransom demand and paid the USD 300? I wonder if they all actually got their files decrypted?
