That's not really accurate. Windows uses 64-bits to determine the time (in 100-nanosecond offsets from January 1, 1601). It won't roll over until the year 60095.
Of course, everybody will wait until 60094 before they start patching.
The point of satellites is they're in space. The point of space is it's notably devoid of air. Kind of makes hooking this kind of thing up to a satellite kind of useless.
Either that or you've got quite the ego to think that you're smarter than ESR.
That implies that ESR is particularly intelligent. Frankly, I haven't seen any evidence that this is the case; most of his writing is riddled with logical errors and flaws. There's a reason nobody really listens to him anymore.
This should be moderated down. It is fundamentally wrong. Angular momentum has nothing to do with thermodynamics.
Momentum is not energy. Angular momentum is always conserved. Just think about it logically - to slow the rotation of an object down it has to push against another object in the opposite direction of rotation - which increases the rotation of that object. The sum total of angular momentum (similar to linear momentum) will always remain the same. This is very basic physics people.
Water spinning in a bathtub will eventually slow down as it transfers its angular momentum to the tub (and the planet itself). But the earth is in a vacuum, there's nothing to transfer the angular momentum to.
I'd suspect almost all of it. The 64 bit chip supports SSE2, has an onboard memory controller and a host of other architectural improvements.
I can't imagine how 64 bit words would significantly improve the performance of anything outside of crypto.
Caldera bought SCO, renamed to SCO then sued IBM. If you think back a few years, you'll remember Caldera buying the rights to DR-DOS and suing Microsoft - but that time everybody cheered.
I guess you can say what goes around, comes around.
...things take millions to develop and thousands of man hours these days not because it actually takes that, but because the men and dollars are available, so they get spent. If these men and dollars were *not* available pretty much the same work would get done.
If it were that simple, why are you posting on/. instead of putting your philosophy into practice and making yourself billions of dollars?
Ion engines don't have the impressive flames of chemical rockets, or the raw thrust, but they have much better specific impulse which is all that counts once you get out of Earth orbit.
But, since the moon is in orbit, thrust is an issue. But the question is, why waste a lot of money getting their fast when you're just sending a robot? It sounds like the ESA is going to get valuable ion engine experience out of this, and at the same time get to the moon cheap. And that's what going to the moon should be; cheap.
If going to the moon isn't cheap, how can we reasonably expect to go to Mars?
How about high energy particle physics. If you're going to do any cutting edge high energy particle physics research done, you've got to work at CERN. The US government cancelled CERN's only real competition, the SSC. And who's ever heard of the Max Plank institute?
Or that little place in England... what's it called. Cambridge. I heard there's a guy there, name's Stephen Hawking? Oh, and we can't forget David Deutsch, he's also there... created quantum computing and all.
Biotech? Dolly the sheep, first successfully cloned animal. That was in Europe. And then there's the Oxford AIDS vaccine. And with the current attitude towards stem cell research, a lot of the American resarch is moving towards Europe and other areas of the world more friendly to it.
Computer Science? Tim Berners-Lee creating the web while working at CERN? Opera is a company in Norway. I suppose that's all pretty unimportant. And I don't think there's any good wireless stuff coming out of Europe either. I mean, there's that little Nokia company, but what do they do?
I heard this guy, called Linus Torvalds, was a Fin (okay, he's moved to the US now). And there's Alan Cox, in the UK.
And what about the brand spanking new American Advanced Encryption Standard (AES) to replace the aging DES, well, that's also known as Rijndael, and was developed in Belgium, I believe.
Or how about major engineering projects? How about the Channel Tunnel?
64 bit doesn't give you significant performance improvements except in a few specialised areas (like crypto).
The point is this: Twice the bits means twice the math getting done in the same amount of time - This is one of the stupidest comments I've heard in a while... think about it for a minute.
And last I checked, most major x86 operating systems supported 64bit addressing for files.
And if you are thinking about RAM, x86 isn't limited to 4gb. It can support up to 64gb of physical ram; Windows and Linux have both supported this for a while now... except for a few AMD chips (a number of recent AMD chips have microcode bugs which prevent you from addressing more than 4gb of RAM).
There actually are some cool things you can do in 64bit which you can't in 32bit. You listed none of them. However, they tend to be closely tied to OS architecture, and even then few OSes take advantage of them (they aren't the kind of things you can retrofit on).
If memory serves me correctly, VC++ 6.0 came out before the C++ Standard was released. 7.0 (aka, VC++.NET) is far more standards compliant. Of course, it's not perfect... most of the issues are in the STL (which you can replace with a more standards compliant version, stlport).
If you need total standards compliant though, Comeau C++ is the tool for you.

Won't be running out of RAM space quite yet.
And realise Sun's primary goal should be making money, not spiting Bill Gates. If he doesn't, this vendetta of his will kill his company eventually.

Firefly was tremendously boring and slow. Good idea, bad implementation.
Uh, no, it' s not. Hence the creation of XHTML.
$123 million * 326? That's only $40 billion. Methinks you misplaced a decimal point, and meant 3,260 times.

A quick link grabbed from google on the subject.

No, that is simply another popular misconception. Begging the question is circular reasoning, no more, no less.

The problem with David Suzuki is he has a definite political agenda which turns a lot of people off.

Getting bought out for a big cash sum doesn't make you profitable. It just makes your buyer stupid. Profit is when you earn more than you spend.

You know, I can go on like this for ages.
Will this affect 1.x or just 2.0?
They're still years behind SGI, who can handle 512 CPUs and 1TB of physical memory. :)
It's called profile guided optimisation. Most decent compilers support it these days.
Wow, 80 threads to build a state machine? What a nasty solution.
You should chuck whatever language you're working in and replace it with one that supports full co-routines.
And last I checked, most major x86 operating systems supported 64bit addressing for files.

Just because you don't understand what they're good for, doesn't mean they're not useless.
x86 (and Windows and Linux on x86) can support up to 64GB of ram, not 4GB.
