1024 CPUs??? WOW... and I thought I had nasty simulations. :o
Still, dont you think that it is a terrible waste of computing power if the app doesnt take advantage of multiple processors, eventhough it might be very hard to write such an app? This is really not my field and I know far too little to have an opinion, so take it for what it is worth.
You had to explicitly write your applications in a special parallel computing version of Fortran or OCCAM. It was exceptionally quick at matrices and vector equations so working out the weather was one of the things it was good at. They did a later DAP with 4096 processors. :-)
The point is, multiple cores are only of use if you've a task that can be split up into separate threads. Many general purpose computing tasks simply can't be multi threaded easily or at all.
On the Mac though, the main advantage of at least two cores is that the OS can run the WindowServer task, that handles all your windows on screen and generally consumes a lot of CPU when you've got 16 apps running on your screen on one CPU and your application on another and it's still nippy so you don't get the beachball so often switching apps. The second core can also be doing something like running backups, indexing a hard drive for Spotlight, hotclustering files, updating thumbnails in iPhoto.... Past two cores and you're in diminishing returns except for specific applications that can be multithreaded.
The one advantage Macs have had for a few years of course is that there is a long history of dual CPU machines. Windows on the other hand rarely has multi threaded applications. Both OS's are a pain in the arse to write multi threaded apps for though. The wisdom of BeOS's designers would work wonders with today's CPUs.

what the heck LOL, this is a joke right? I have NEVER seen a single new windows phone being used in public nor do I see that many Android devices in the UK. mostly I see
1. BlackBerries
2. iPhones
never seen a new windows phone LOL, most people who are happy with iPhones etc, will stick with them and won't bother going for anything else.
Windows Mobile is doomed for failure, how many times has it been revamped and rebranded over the years? like 3 or 4 times if I remember

I wouldn't go so far as to kill someone. If I killed them, how could they learn a lesson?

What if your actions unintentionally led to the death of another? What would it take for you to learn your lesson?
Your car is a lethal piece of machinery over which you have only limited control, even less so when you go over the speed limit.
Remember, no one enters their car with the intention of making a lethal mistake, but it happens all across the country every day to hundreds of individuals, many of which thought exactly what you're thinking right now.
Just ponder it.

This is the most credible of the iPhone rumors I've seen so far-- in no small part because it didn't have a picture attached... The feature set sounds right, the move away from doing everything from the ground up sounds right. There's a lot of companies that have put a lot of effort into building technologies for cell phones-- it would be foolhardy for Apple to think they could do everything better. Get into the market with something that innovates in one small area-- even if that's just in its support for iTunes. Once you understand the market a little better, improve on the pieces you think you can.

I use both.... and all I can say is "CUT and paste". Windows has had it for years, OS X SL doesn't. Same with window snap.
I love OS X, but, like with a lot of Apple products, its the "little things" that matter...
Both are great operating systems, and I will continue to use both since I cannot run Visual Studio on Mac, or XCode on Windows... :)
It does have CUT and Paste.
Command-X = Cut
Command-P = Paste
Command-C = Copy

It goes to show you what our legal system really is like. Kind of goes to show you that much of our legal system is nothing more than expensive babies fighting. Also goes to show you why our government is such a mess because guess what most of our political leaders are........ You guessed it LAWYERS. This is pretty much a world wide thing.
Yeah -- makes you wonder why the American Revolution ever happened. We replaced somebody who ruled by birthright with somebody who ruled by the merits of being a better lawyer. I guess you can't win. If only all political leaders could have been like George Washington who hated political parties.

Aung San Suu Kyi was awarded the Nobel Peace Prize in 1991. The decision of the Nobel Committee mentions:[135]
The Norwegian Nobel Committee has decided to award the Nobel Peace Prize for 1991 to Aung San Suu Kyi of Myanmar (Burma) for her non-violent struggle for democracy and human rights.
...Suu Kyi's struggle is one of the most extraordinary examples of civil courage in Asia in recent decades. She has become an important symbol in the struggle against oppression...
...In awarding the Nobel Peace Prize for 1991 to Aung San Suu Kyi, the Norwegian Nobel Committee wishes to honour this woman for her unflagging efforts and to show its support for the many people throughout the world who are striving to attain democracy, human rights and ethnic conciliation by peaceful means.
�Oslo, 14 October 1991

Isn't that the same thing as assigning priorities to processes in OS X? Terminal or Developer Tools already do that, as well as several freeware apps...
No, not at all.
An affinity mask sets the set of CPUs that can be scheduled. A job won't be run on another CPU, even if the assigned CPUs are at 100% and other idle CPUs are available.
And that, by the way, is why setting affinity is usually a bad idea. Let the system dynamically schedule across all available resources -- or you might have some CPUs very busy, and others idle.
Win2k3 also has "soft" affinity masks, which define a preferred set of CPUs. If all of the preferred CPUs are busy, and other CPUs are idle, then soft affinity allows the system to run the jobs on the idle CPUs - even though the idle CPUs aren't in the preferred affinity mask.

It's not just about power. I would never buy an iMac because I like being able to actually upgrade my components as they get older. With the form factor of the iMac, you get all of the disadvantages of a notebook (less harddrive bays, less ram slots, no expansion slots) with all of the disadvantages of a desktop (namely, it's not portable). It just seems silly to me.
Additionally, I hate 16:9 displays (16:9 is tv widescreen, 16:10 is computer widescreen) and I would much rather use my own displays (2x dell ultrasharps) than the ones apple makes, so building the display into the computer is a disadvantage to me.
Sigh... It's a shame really, I don't need nearly the kind of power that even the lowest Mac Pro has, but it's the only desktop mac that I could buy at this point.
Don't despair.

The current enclosure is very nice, so why change it?
Because people are so scared of immediate obsolescence that they'd rather hope for a new enclosure than enjoy what is currently out. It gets really old.

Well I'm sorry to hear that happened to your father. My mother was in a similar situation a few years back. She cut off an idiot doing 20 under the speed limit, slammed on the brakes, and there was a wreck. The guy she cut off was found to be at fault for not maintaining a proper distance, my mother was not found at fault. She openly told the cops that she had just passed the guy, and after she passed she thought she saw a squirrel enter the road, so she slammed on the breaks. On top of doing $15,000 grand worth of damage to the guys car (which he had to pay for due to not having broadform insurance) she then sued him for her $2,000 deductible, and won. Sucks to be him, maybe he does the speed limit now.
-Don
Wow, your mom willingly caused a wreck, sued the guy, and you are proud of it. Man, you and your family are just pathetic.:rolleyes:

Apple sends out invites that seem to indicate a moviestore, rumors abound about new nanos... and what do the forums turn into:
"I hope they release a phone."
"New macbooks please!"
"Apple DVR!"
:confused: :o
Where do they come up with this stuff?

One more reason to long for a jailbreak on my iPad 2 so i can fix this privacy issue!!!!
Edit: if the iDevice ****s up if you cant wright to this file, simply symlink it to /dev/null (or what ever the osx alternative is)

They don't want to call their store "MobileApp" because they already have a store. It's called "Marketplace".
They would however like to describe their store that called "Marketplace" by saying that it is a store that sells apps. You know, an app store.
It is a market that sells apps. You know, and app market. No need for them to describe it as an App Store since that description would not fly over anyone's head.

I am not sure about other states, but in CA, Law Enforcement is specifically required to announce DUI checkpoints and provide an alternative route. Asking to have these applications removed from app stores contradicts the law regarding DUI checkpoints. Gotta love Politicians. Write a law then contradict it. Awesome.
