My bad. According to http://en.wikipedia.org/wiki/Saturn_V#S-IC_first_stage the first stage uses RP-1 (aka kerosene) and LOX. I thought it used liquid hydrogen.

As for most exotic and difficult to handle fuel, I think that would include liquid fluorine (FLOX) or nitrogen tetroxide.

"Our Environment. Sure launching a rocket into space take huge amounts of carbon."

So what takes a large amount of carbon?
Burning liquid oxygen and hydrogen?
Manufacturing the liquid oxygen and hydrogen?
Manufacturing the aluminum?
Perhaps it takes a lot of *energy*, but I don't know where a huge amount of carbon is involved. Help me out.

I have no problem with it. He has no responsibility to microsoft, or to anyone who has purchased microsoft software. He did the research on his own time. He owns it, and is responsible only to himself.

I see nothing inexcusable about it. If you don't like it, you should pay someone to find bugs with the software you use. You can do that, but I bet you don't. If some bugs are found by someone, it sucks to be you. Get the source code and audit it yourself. You do have a microsoft windows source code license, right? If not, whose fault is that?

I write software. Sometimes I publish it. It is my work. Sometimes I find bugs. I have reported bugs to DEC, prime, microsoft, sun, redhat, fedora, suse, mandriva, mageia, and others. If they listen to me and respond, then I report more bugs. Since microsoft ignores my bug reports, I have stopped sending them bug reports. My choice.

So how was it wrong?

He did some research.

He published it.

Was he under any obligation to show it to google? to microsoft?
I don't think so.
This 'protocol' you speak of is just what some people want. That doesn't make it correct, common, or required.
He has done nothing that should get him fired. If he were, he could sue someone's a$$.
Get a clue.

Is he on microsoft's payroll? If not, why should he inform them? Because they screwed up and didn't find their own bug? He can do whatever he wants to do with his research. He can tell Microsoft. He can post the info. He call sell it to the highest bidder. It is his work. If microsoft really cared, at least they could offer a bug bounty. That would show they are serious about getting bugs out of their software.

It was a blue pick up truck, not a van, but it certainly was not a nissan titan, nor was it the correct color.

I suspect that the people who shot up the 2 vehicles, will end up paying a high price, which really means that the people living in the cities will end up paying a high price.

There is no car made that has a more powerful engine than the brakes. What is interesting, is that even if you are going 200kph, have the throttle fully depressed, it only takes about 10-15% longer to stop the car using the brakes. I think that Jay Leno made a car with a monster engine of around 20+ liters that had crappy drum brakes. For that car, I don't think the brakes would stop the car if the throttle was fully depressed. A few years ago, car & drive did a test using a 400+ hp corvette. Stopped just fine. If the brakes are defective, of course all bets are off.

I am not sure what you mean by 'comically thirsty'. Mine usually gets 60 miles per gallon. The worst mileage I got was when I drove in the desert when it was well over 100 degrees F, and I was driving 80mph. I got about 48 miles per gallon. I suppose there are some turbo diesels that get better mpg, but they are not sold in my country. I think you are a bit confused.

Your custom solar panel produces 600w? Where? In outer space? I have 200w panels, and I don't think 2 would fit on top of a pathfinder. And mine are 18% efficient at the panel level, which is pretty efficient. Perhaps if you use multi-junction space grade cells, you could get 600w, but that would cost more than a new pathfinder.

That is because Neil Armstrong was being interviewed by Sir Patrick Moore https://en.wikipedia.org/wiki/Patrick_Moore Moore is a pretty famous amateur astronomer, who is quite well educated in astronomy. Sorta analogous to Carl Sagan.

If you had a contemporary interviewer of similar stature fo Moore, I suspect they would ask similar questions.

The only question is would it air on prime time TV. In my opinion, British TV is generally far more scholarly than US television.

I am not sure what an 'expensive expensive' gun safe is, but the gun safes i have seen that weigh 500 come from costco or sams club and are not expensive. It is hard to imagine a house fire hot enough to melt steel. Even 9-11 only partially melted the steel structure. You would think a large steel box should be easy to spot after a fire...

The solution of this problem is trivial and is left as an exercise for the reader.
