i think people missed the importance of Dashboard (coming in Tiger). They seem to think its all about "widgets". IMO its all aout writing small apps for the Mac using Javascript and HTML. So now, if you can design a web page, you can develop apps for the Mac.
AFAIK the above posts are correct, the instruction sets are stil 32 bit.
Unlike some of the other posts though, I'm not worried about RAM or hard drive space, I'm worried about L1 and L2 cache space. If a sizable amount of the data cached goes from 32 to 64 bits, the processors could take a big performance hit unless the caches are bigger too.
Here's hoping programmers keep using 32 bit data structtures when they don't need 64 bits!
is there another reason to use liquid cooling, other than excessive temperature?
Not sure if this is the reason, but its not just a matter of amount of heat generated. Its the amount of heat generated in a given area. So if you generate the same, or even less, heat in a smaller area, you may need to resort to something more efficient that air cooling to do the job.
IIRC, even the G4 doesn't need to break 64 bit floating point operations into 32 bit operations. IOW, the floating point units in the processor have been 64 bit for some time, its the rest of the architecture that's just "cacthing up".
As is mentioned in the article, it is about design, not assembly.
"From the NASA report, it seems that the accelerometers had to be X-rayed to determine the internal up-down orientation of their sensors, which reportedly were described incorrectly in the technical drawings."
There are two design flaws right there. First, you shouldn't have to X-ray it to determine orientation, second that the drawings are incorrect. So everything was assembled according to the techinical drawings.
So the company that built the sensor built it according to spec, and the person who bolted it onto the craft also did so according to the specifications.
Maybe we're just arguing about semantics, but I'd say all the flaws occured during the design process, not the implementation or assembly stages.
Now suppose this output is double-checked by another engineer, who also has a 5% chance of error. 95% of the first engineer's errors will be caught, but that still leaves a.25% chance of an error getting through both engineers.
OK, nitpicking here. My statistics are a little rusty, but I think you got that wrong. You calculted the joint probability that both would miss a flaw. What you want to calculate is the probability that they will both miss the same flaw.
So there's a 5% probability the first one misses it, but a 95% chance that it will be caught by the second person. So, 5%-(95% x 5%) leaves only a 0.25% chance that both will miss it.
Either way though, your point is correct. There will always be a finite possibility of failure.
Should also acknowledge that there are also a lot of other assumptions that we're probably both aware of.
NASA really doesn't have much room to manuver. If they build in too much tolerance, the program costs too much and will never get funded. Not enough and you risk catastrophe.
Said another way, any time cost becomes a design contraint, some other variable (i.e. safety factor) has to give.
I was thinking maybe he was referring to the drive-less eMacs that can be ordered along with an XServe for netbooting. Don't know if other parts, like modems, were left out of those as well or not. IIRC they're not sold through the "normal" Apple store and are usually purchased in pallets of 20 or so to set up a lab.
Theese people would swear that USA was the most technologically advanced country, that USA had the best democracy,
Maybe I'm missing something, but depending on how one defines "most technologically advanced" and "best democracy" I think one could make a good argument that the U.S. is the best. Others could equally well argue that any one of a dozen other countries are "best". I see nothing wrong with that.. Why are only Americans considered arrogant simply for showing pride in their country.
How much news are there where they describe how it's done in other countries?
I'm not sure exactly what you mean by this, but I often see news presented by non-American reporters in other countries. When they do use American reporters, they're often interviewing someone from the country they are in. Also, we do get newscasts from other countries here. And you wouldn't believe how much fun I have watching the "Prime Minister's Minutes" from the UK.
With regard to music, I hear a lot of international music. I'll admit the overwhelming majority of the music with vocals is in English -though a lot of that comes from Canada and England. In fact, many of the most popular bands in the US seem to origninate from one of those two countries. A lot of the rest I get from my sister-in-law who sings classical opera -none of that in English (some in Japanese, though I'm not sure if what I have is technically opera).
Movies -I think you'd be surprised. Books? I read a lot of the classics that were originally written in Greek, Hebrew or Latin. Actually, now that I think about it probably around half the other books I read are written by authors from other countries. And not all of them need to be translated. Like music, at least one of the most popular authors in the US isn't a US citizen (think Harry Potter).
You gaze at your navel, you learn nothing.
A little self-reflection never hurt anybody:-) American or otherwise.
Bah, that's just wasteful pedantism. "Americans" has referred specifically to residents of USA forever,
Maybe. I just often wonder how it came to be used like it is. Does it seem right to you?
If you tell a Canadian they're "American" you will be lucky if you get away with just a verbal lashing.
Aint that the truth!
Canadians call themselves "Canadian", never "American".
Just FYI, when abroad, many Americans calls themselves Canadian too. It avoids being treated as a stereotype rather than an individual.
As a final note, I really don't want this to be a US vs. the world debate. I just don't think "Americans" are really quite what many people from other countries think. Believe it or not, we aren't all the same and we often have radically different views.
Said another way, When they installed the part, they installed it with the "Up Arrow" pointing up like the directions said, but the people who designed the part had the "Up Arrow" pointing the wrong direction.
So the failure was in design, not installation. The net result still being it ended up backwards.
I will remain skeptical until I see some government accuse IndyMedia directly
I don't think that's necessary to stay within the law. IANAL, but I don't think you need to be the one who committed the crime to have your assets taken. You only need to be in possession of evidence.
For example, say my car is stolen and used in a crime. It may be impounded as evidence, even though I did nothing wrong. I may not be happy about it, but I understand the need.
The same may be true here. It doesn't matter who owns the drives, if they contain criminal evidence, or even evidence of a crime that is going to be committed, they can be seized.
So for now, I'm still witholding judgement until I see where this leads.
the Americans have let it happen, because they've become slaves to the corporations, because they refuse to look beyond their borders and look at what other countries are doing better, because they're so arrogant they think they're best at everything.
With all due respect, do you actually know many Americans? What you describe fits the stereotype, but I don't know any indivudual Americans that fit the description. From another perspective, if you watch the news, its 90% about what's going on in the rest of the world, including a lot of "what the world thinks of us". From what I see of people outside the US looking in is they don't seem to understand that many of the same questions and criticisms they have are the same things people in the US are talking about every day.
On a different note (and I mean the following in a good-humored way)..
And stop equating USA to "the world" that's just ignorant. We probably will when people stop equating America with the United States of America. Hint: the USA is only one country in the two continents composed of North and South America. I often wonder how the citizens of other countries in North and South America feel about "Americans" being used to refer to the residents of the U.S..
Just the idea that the only thing keeping me from a neverending journey into space is that a remote mag-beam emitter will be exactly where it needs to be at exactly the right time and be fully functional...
Sounds to much to me like being shot out of a rifle and hoping your aim is good enough that you will go straight down the barrel of the "receiving" rifle millions of miles away.
My mind is just boggling at the distances and the accuracy required for this to work. I assume that just because they won't carry "big powerful propulstion units" doesn't mean the won't have some darn good navigational units to adjust their course.
The brake is a remote emitter that has to hit a small craft going 26,000 miles an hour with a stream of magnetized ions. Granted, the craft will hopefull be coming straight at it, making targeting easier, but I be the military would love to be able to hit a target that well.
I hope the craft will have at least some small thrusters for adjusting its course, because you're going to have to be headed straight at that "receiving" emitter or it will just will just slow you down a bit and alter your trajectory.
I'd hate to be on the ship when the remote emitter either misses or simply doesn't work.
Plus, going horizontally does no good unless you're using "wings" or an airfoil to give you some lift. Otherwise you're just fighting gravity that much longer.
Though the shuttle does have wings, they're not going to do much when weighed against the mass of the large boosters and fuel needed for launch.

magnified by poor management, again here on Earth.
Are you seriously trying to tell me that "management" isn't from another planet?

And building in fault tolerance costs money.
NASA really doesn't have much room to manuver. If they build in too much tolerance, the program costs too much and will never get funded. Not enough and you risk catastrophe.
Said another way, any time cost becomes a design contraint, some other variable (i.e. safety factor) has to give.
The sad thing is that by the time we launched the last Saturn the worst of the bugs had been resolved, just in time to stop flying them
Sounds like most soft- and hard-ware. About the time the bugs are ironed out, its time for the next version with new bugs.
If bush wins the election, you will see this case quietly vanish into the ether..
Not only that, the price of tea in China will skyrocket!

Deep space, here we come!
I think I've said this before, but the nearest asteroid to earth is worth something over 3 trillion in materials.
And it would only cost 30 trillion to get up there, mine it, and get it back to earth.

People seem to forget that we've had people in space for relatively long periods of time.
