seriously though, how hard is it to get a program to multi-thread? (if thats the right term; being a complete programming novice, i've no idea)
That really depends on the program, on how "parallelizable" the application is.
The simplest way to think of it is like this: Let's say you have a program that first has to calculate A. Then, when it's done that, it uses the result of A to calculate B. Then, when it's done that, uses the result of B to calculate C, then C to D, and so on. That's a *serial* problem there. The calculation of B can't begin until A is done, so it doesn't matter how many processors you have running, all computation is held up on one spot.
On the other hand, let's say you have an application that needs to calculate A, B, C and D, but those four values are not dependent on each other at all. In that case, you can use four processors at the same time, to calculate all four values at the same time.
Think of it like baking a cake. You can't start putting on the icing until the cake is done baking. And you can't start baking the cake until the ingredients are all mixed together. But you can have people simultaneously getting out and measuring the ingredients.
So that problem is partially parallelizable, but the majority of its workload is a serial process.
Some software applications, just by their very nature, will never be able to do anything useful with multiple processors.

I don't think that's a first-gen, mate. The first gens were acrylic:
The acrylic ones are the Apple Studio Displays. They've been the Cinema display since they moved to aluminum.

Small Pelican case for my Oakley Glasses, (as seen on the last page of the XIV Purchases Thread)
Have room for another pair too, Maybe I'll find another pair that I like in the future.

Why would updated mac minis be such a high security product. Its nothing revolutionary so why would apple want so much security on the shipping of them? Im hoping for something BIG

My goodness...
I'm just hoping Apple continues to make a few machines that can do actual design and coding work.
A touchscreen iPad, iPhone or touchscreen "anything" really doesn't work for that.
Some of us love Apple gear but actually want to get some efficient and creative work done.
Note to Apple: Not every device has to be a whiz-bang, wow 'em at Best Buy, touchscreen device with more reflection than a mirror and finger smudges all over it.
Speaking of which...The Mac Pro ever getting updated again Apple?

An undocumented source proves your point, but Apple makes no reply to the allegations? I thought it was a "bug" in the software? And some police departments have known about it for a while too.
Who needs an undocumented source when you could watch WWDC 2010 Session 115 'Using Core Location in iOS 4' at 14 minutes and 30 seconds in and hear Morgan Grainger, a man partly responsible for the Core Location framework in the iPhone SDK (read: all location functionality on iPhone) describe how the iPhone caches nearby cell tower information to help the device find its location in the circumstances above.
Given that we have the engineer partly behind this framework explain that the iPhone caches this information, we know that the iPhone has to be storing this information somewhere. This 'consolidated.db' matches the words in the video perfectly, making it no great assumption that this is the file which fulfils this purpose.
Granted you don't sound like a developer and so won't have access to these videos, but any other developer could do the same and corroborate this.
It being a bug is simply a rumour which has no links to an official source. I'm far more inclined to believe the words of a guy who wrote the code that collects this information in the first place

What do you mean by "G5"??? PowerPC is long gone from Macs.
As other people have recognised..... the reference to G5 is in relation to the design not the chipset inside.

Yup.
You know I am almost always critical of US military action, but in this case...
It might need to be taken.
We do have an obligation to stop atrocities if we are aware of them.
That said, this needs to be an international action, not like the "coalition of the willing" that went into Iraq. In fact, id prefer it if the US was NOT the main force by any stretch. We should give plenty of support, but we should be careful to not give the impression that we are taking the primary role in another conflict.
phht...I'm pretty sure the reason why there is "international action" this time is because it's not only easy to justify, but it has been clearly demonstrated that the US "going in" will result in victory. And this is a tiny weak nation too. At least Iraq was able to off a decent amount of "coalition forces" even though it's still a pin prick. And since Lybia has a lot of oil, "other nations" will be really easy to be persuaded to "save lives of rebels" or whatever. Heck, even the "French" are throwing on the gloves. Which I'm sure many ppl feel we should just shoot them out of the air ourselves. :p I mean, the Frence aren't going to miss out on this one, especially since it's like a given victory with "air support".
I mean, this "cease fire" that's going on. Why is there no ceasfire? Because the West doesn't want it. It's already in motion. Whether it be jamming communications or "rebels staging attacks on themselves for show", it's clear that we've made the decision to go for blood...civilians or not in harms way...to put the regime WE want, into power. They aren't "peaceful"...they look just like those in that picture above in the truck. They struck a deal. Oil for help. And the Frence sadly are apparently in on it too.

No chance. The ergonomics would be a disaster.
I second that. I have both an 27 iMac and the first aluminum Macbook with a Multi-Touch trackpad and touching on a screen would be quite uncomfortable. I'd rather use my macbook's Multi-Touch trackpad than the magic mouse.

but they buy it for their kids... c'mon, apple is HARDLY lost when it comes to marketing... many of my PC friends rave about the way apple has marketed the iPod and their iMac... many of them are switchers because the comercials got them interested

I was trying to avoid the whining, but now that you bring it up... when is apple going to bring the video content to other coutries?
In Belgium, we were promised video downloads in 2006
Yeah, if it's $9.99 to rent, it's going to fail. $1.99, might be worth it. I'm sure a lot of people will be happy, then a lot of people will complain. Both with have good points, but the rest of us won't care.
Yeah, $2 seems right for a movie (in twisted Apple calculations this is 2,49 euros) I normally watch movies only once, so rental would be better, especially with a modest hard drive
We can always hope that they also want to make business outside US.
Amen
Surely the TV Shows issue is because the US shows are sold on to European TV Stations, usually after the show has aired in the states. These TV Stations aren't going to be too pleased if they've shelled out a bucketload of money for the UK premier of 24 for example, only to have it show up on iTunes before they've even aired it.
The only way it can work is if iTunes waits until after all the channels have aired it first. In the UK you'd find 24 showing up on something like E4, then Channel 4, then some of the scrubbers like Channel 5 or Bravo would likely have a deal, then it could show up on iTunes. By then the show is so old that there's no point. Hence, I imagine, why we don't get iTunes TV Shows here.
The shows would probably be different in the international stores, like here in Belgium we will have to split, one for Flanders (Dutch subtitles, although a lot of people also know English, like me) and one for Wallon (French dubbing/subtitles)
And there would probably be an offer of Belgian TV shows, along with international ones that have already aired here. I do hope we will have the chance to buy some more shows that, won't come out in Belgium, at least not on DVD.

Well, the US controls the AWACS so that kind of says the US still prolly running a big part of the show in reality. Also the tomahawks are flying arround too. I would doubt US command is taking orders from the Canadians. I wonder if the US is purposly trying to "hide their face" given the fact that much of the muslim world resents them for leading the past 2 wars.

Folks need to be careful when making G5 to Conroe/etc. comparisons....
The PPC 970FX (single core G5 which was in the iMac G5) has a TDP below that of a Conroe.
FX was used in the xServe, and they couldn't get dual-core CPU in there. As soon as they moved to woodcrest, they could replace that 2x G5 with 2x dual-core Woodcrests. Says quite a bit about how hot they run....
