It's just the warranty, or mission success criterium. If you look at the specs, there isn't a single part of the rovers with such a limited lifetime. For example, the batteries have a 1000 cycle lifetime. The big problem is that there were many unknowns. Landing on mars is a tricky business, two out of three missions failing. They sent two rovers to maximize the chance of at least one of them reaching the surface intact. Further bad luck (a global dust storm, or landing in the middle of a nasty dune field of for example), could further have limited the mission lifetime. And they really needed succes, so they set the goals to "realistic" levels. (Or put another way, they over-designed the robots).
But once they had the two rovers safely on the ground, you could already tell they were going to outlast the warranty. Why even try to reach the Columbia Hills if the rover is near the end of it's lifespan?
I still remember a comment by Steve Squyres not that far in the mission stating that the rovers could still be be going "next summer". He wasn't specific (on purpose, I guess), but I think he didn't mean the next earth summer (a few months), but the next martian summer (it was still autumn on mars back then, so that's more than an earth-year).
Nitroglycerin does *not* require a booster charge, in fact it's one of the most unstable substances known. It's shock-sensitive, heat sensitive and even looking at it might set it of (metaforically speaking). One of the biggest problems with dynamite is that it can start to "sweat", i.e. the nitroglicerin coming free from the clay. When that happens, you're in deep doodoo.
Sorry for the blunt subject, but would you please take the time to look at the recent amount of xbox titles and imagine the marketing machine behind it? I'm being slapped in the face by xbox stories around the clock, and I've had enough of it.
So I decided right here, right now to start a small anti-campain.
DON'T BUY XBOX!!!!! IN FACT, DON't BUY ANYTHING COMING FROM THAT EVIL COMPANY, WHO'S INTERESTS ARE ONLY SELF-CENTERED AND TO WHOM YOU ARE NOTHING MORE THAN A MAGGOT. I WOULD EXPLAIN ABOUT MICROSOFT'S MALPRACTICES HERE, BUT UNFORTUNATLY THE COMMENT SPACE IS IS NOT BIG ENOUGH TO EVEN GET ME STARTED. DEMAND RESPECT, BOYCOT M$!
Disable the Java, and your startup time is almost certainly going to improve. [Another Slashdotter showed me this trick, and it apparently disables macros or something I don't use much if ever.]
It will give problems making database forms, for example. If you have database problems (not being able to edit fields), it's possible Java is disabled.
The tests I did was with nitric and sulphuric acid mixed together. The sulphuric acid's role was indeed to boost the reaction. But if my understanding is correct, the nitric acid alone can also form nitroglycerin, just less, and it's slower. It could be enough to produce an audible bang.
I liked the exploding bubble. The article didn't say much about it, but my guess is that it might have been nitric acid reacting with glycerin (producing.. nitroglycerin!). Glycerin is often used for making bubbles, it allows them to grow larger.
I did some experiments trying to create nitroglycerin when I was 17, but later I learned that the nitric acid sold commercially contain chemicals that inhibit the reaction (the bastards!). Maybe the guy found a way to inhibit the inhibitor?
The converted ICBMs used for satellite launches can only deliver small cargo's in low earth orbit, so I don't think they will be able to reach the moon with a nuclear warhead. They were never supposed to neither. Their goal was to make half an tour around the globe and vaporize some evil (communtists|capitalists).
That could make sense, I read an article a while ago that explained about sport drinks. It stated that you best drink a lot at once, instead of taking small sips over time. If you apply your theory, this would mean that starting up digestion time after time would cost a lot of energy, making the drink less effective.
Personally I lost my own overweight simply by blocking the calory intake after dinner. During the day I eat normally and drink soda, but after dinner I switch to water and stop eating candy/snacks. The weight loss was about a kilogram/month, but it kept going down for more than a year.

One word: significant figures. ... D'oh!

There is a "Always save as" field in the lower right.

Aah, Australia, the upside down world... Makes sense.

While you're at it, try out some documantation extraction tools, like javadoc, ccdoc, or others.
Sony denies penalising internet shopping sites, arguing that it is rewarding stores that can demonstrate its products.
Can someone explain me the difference?
Does this mean that Professor Sutherland is cursed, since he's caused Shakespeare's corpse to spin at such a rapid rate?
I think he just found an alternative to the "cat with buttered bread on back"-style power generator.
Why did it get arrested in the first place?
If I were them, I would go searching for another provider.
Are you only interested in thrown stuff or does "tuning it with a very large hammer" count also?

Don't virusses need needle-like structures to insert their DNA? These things look like small round balls. How do they inject their "root kit"?
You might sign the petition against the data retention proposal in the EU then (see sig).
Maybe you could throw in an occasional poisoned cigarette causing instant death? Is sure would add to the thrill..
Mars doesn't 'appear', it's just like a bright star when looking with the unaided eye. A bright red star. You can't miss it.
The content of the .ram file shows http://www.earthstation1.com/WOTW/War_of_the_World s.ra for those who prefer wget.
Darwin has a mach-based "microkernel" but there's only one thread running under it - the FreeBSD kernel.
So - in theory - you could add other OSes in other threads? Can this be used for virtualisation? (think user-mode linux under darwin).
In what way isn't it relational?
