I wonder why this is not something that is kept up to date anyway. I can see keeping B an update or two behind A to prevent a single programming error taking both of them down. But after you are satisfied with A's software load, why keep B so far back-level that transition takes so much time. And since the computers are said to be identical, why the desire to move back to A?
I can easily imagine this happening, I work on a very similar, perhaps nearly identical spacecraft (that's just a tad mode critical AND expensive than this thing...) and we haven't necessarily maintained this. You underestimate the overhead associated with generating the necessary uploads.
The reason they probably want to go back to the Prime is that their failure isolation system database is keyed to using the prime units only, and to alter it to start on the "B" side and have it switch back to "A" is prohibitive, or at least easier to get around by switching back to A. This last is also something we do in the rare case of a temporary failure. There's less good justification to doing it than leaving the backup program image alone but having to completely retest the entire redundancy management system for a new configuration is generally avoided. If it fails hard, it doesn't really matter, since there's no Prime to switch back to.
Frequently, but not always. It's not unheard of to open and close the source pressure valves, because you don't want to count on the regulators not leaking for any significant length of time. If you leave the source pressure connecting, any regulator leak will likely overpressure the tank. We don't usually do that but it's not uncommon. I would much rather take my chances on valves sticking closed than on regulator leaks.
What in the world are you talking about? Very few connections are hardwired, almost everything has a plug, usually, a rotary cam-lock plug from Cannon, etc.
Do you think they solder all the avionics in place?
No! Most likely, it would have incinerated the parking brake in seconds. That would have been preferable to the other possibility, that is, locking up the rear wheels and spinning out.
That parking brake is NOT an emergency brake unless you are going very slowly and very carefully use it.
On the surface, Paul says a lot of things I would generally agree with. Once you dig for a while, you find a lot of stuff that is utterly loony/suicidal. The Pualbots are even more absurd.
Many good reasons that this is a bad idea already listed. However I would also note that in my quaint notion of how the Federal government is supposed to work, the Executive Branch doesn't make the laws, so asking the Obama Administration to make this legal doesn't even make sense. They can write their Congressman, except, oops, they are all trying to remain Anonymous.
the only good thing about GIMP is that it's free. Otherwise it's torturous to use. No way is it a real competition to photoshop (which is slightly less torturous) Yes, I know I could go in and help fix it but my first step would be to delete all the code.
It'a being overstated in the most hyperbolic way possible, so it will have this effect.
However, remove the hyperbole and this does appear to be a very significant expansion of scope. The leftist need to exert control and disdain of the constitutional protects is evident all over. This sort of expansion of role appears to clearly violate the Frouth Amendment, We are in a mad rush to further impinge the second amendment to "save the children" even though the venue for the most recent mass shooting was a "gun-free zone" already. We have, as recently as yesterday, had elected officials suggest that certain political groups (i.e. conservatives) should have their First amendment rights restricted. The abuse of the Tenth Amendment is rampant and effectively being used to infer that Federal government action is effectively unlimited. All of these "Expansions" are in diametric disagreement with the Ninth Amendment, as the right provisions of the Constitution are being interpreted (as is suits the arguers) as the sole rights granted, which is certainly not the intent.
Best of all, the alleged "Paper of Record" for the US, in reality a parochial leftist mouthpiece/propaganda organ, the holy New York Times, has published a screed that suggests we dispense with the Constitution entirely, as "inconvenient". This was the intent, to make it "inconvenient" on those politicians who wish to impose tyranny (like the TSA represents).
Unless and until legal action puts a stop to this nonsense, we are headed right down the road suggests.
People have been pushing this sort of foolishness since the beginning of the space age. Man under zero g would panic because he is falling, his heart would stop, it would cause him to suffere sever vertigo, etc. Virtually all of it has proved to be nonsensical, the few exceptions were not predicted ahead of time. If it was left to people like you, we would still be living in fear of steam engines or fast horse rides.
My first reaction was that it was incredibly juvenile and poor quality with the obvious puppet strings, etc. Of course, I had no idea who Anderson was and assumed that what I was watching was a current production. I did a little research and realized who he was and what I was seeing.
I realized just how amazing it is that so much creativity can be wrung out of a medium which has fairly severe inherent limitations, at least when compared to live actors or animation.
Needless to say, you were not the target audience. But as you say, a lot of creativity and they made good use of what they had. The Supermarionation process was actually quite technically advanced. The mouth movements were electro-mechanically synched with the sound. The heads on the early puppets were so large because the necessary solenoids and electronics were big. Later, with Captain Scarlett, they were able to shrink it down to anatomically accurate dimensions. But it lost something - it's like hand-drawn cartoons VS the God-awful computer animation. The first one you know is fake and you get past it, the second is in the "uncanny valley" - not quite real but not quite fake enough.
Thunderbirds was *extremely* popular in the US. It was on every afternoon for a long time. It was one of my favorites as a kid - when I see the old ITC logo/bump hear the music, I still get a bit of a jump, because it immediately preceded Thunderbirds. If it came on right now, I would watch it.
The others, not so much. Fireball XL-5 and Captain Scarlet were pretty well-known and UFO was pretty obscure.
Space:1999 was well known although most people thought it was garbage and some of the episodes were just embarrassing from start to finish - a few examples:
they go through a field that "de-evolves" some of them to cavemen, and it also "devolves" their CLOTHES. I even called that one as it happened "don't make their clothes change, too!" and yet it happened anyway.
one had some aliens make an atmosphere on the Moon (so they would stay up there, and not land on the planet until they were out of range), and we found that they built Moonbase Alpha with WINDOWS THAT OPEN, and that the staff *brought beach toys and bikinis*. On a trip to the moon.

Given that this is equally fallacious, almost the same relevance.

Sorry, that's original research. Reverted.
Does this mean I can have edit wars while driving in my car?

They know their audience well. Both of them thought this was a good question.

Panda blood works OK, by I prefer golden lion tamarind placenta, with a dash of powdered black rhino horn and an eye of newt chaser.
Actually, forget slashdot. And the blackjack.

You are the same guys who blindly accept every single global warming scam based on the infallibility of science, right?
If only TVs had a way to change what you see, or be turned off.
Purple hair, too. That Colonel Lake was one of the most attractive ladies on TV at the time, as far as I am concerned.
It was a lot like a live-action version of "Captain Scarlett" and really creepy. They kidnapped people for *spare parts* and breath that green liquid.
