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.
What a very lovely analogy. Thank you.
For me... 8 cores for the bragging rights only... so I guess I won't get one anytime soon. I'm sure 4 would suit me fine though, I need to upgrade my 1Ghz G4!!!

It's not about being groundbreaking perse. It's about making the look & feel of the UI similar to iOS devices so that those who use are using iOS devices but switching to the Mac don't have a steep learning curve.
Makes sense to me.
But they could have made it much better, intuitive and easy. It doesn't mean that going from iOS to MacOSX, you are going to deal with the computers, the same old way.
People are not pointing with fingers and now they have an extra real estate. A mouse has both right click and left click which in my opinion, every computer user knows about.
For a second, forget that you have never seen iOS, but you want to delete the app from launchpad, the only way that comes to your mind is either:
holding the app and dropping into trash OR
right click -> delete
It doesn't have to be the same, seriously.

Those toolboxes are quite expensive. Any reason you chose one of those over, say, a plastic rolling cart from Ikea?
No Ikea for about 500 miles from me. They made a ton of different series from cheap crap to the really nice stuff. Mine was the middle on the line and was $179.00 on sales.

Historical observation: The Iraqi people never asked for US help, but there we were.
[...]
That's why the US shouldn't have invaded Iraq.
All about the oil... "protect the citizens" is a perfect excuse. Sadly, because this is what it should be about.
I don't think so. Gaddafi willingly traded Libya's oil, currently no oil at all is traded, and I don't think the rebels (unorganized as they are) will do a good job at it anytime soon. The nations now supporting the air strikes against Gaddafi would have been better off quietly sending him weapons to mute the rebels if they wanted oil.

one of the key differences between the xbox and zune. is that microsoft only had to contend with 2 other players in the video game indistry. the ipod maybe top. but there are hundred of other companies to battle first just to reach second place. and also phone companies. spending money maynot help them like in the case of the xbox.

I have had a Golf TDI for 10 years. I bought it new. It currently has 218K miles on it. It's been a fantastic car. I commute 80 miles daily and get 45-47 mpg (depending on my foot).
The reason the newer Common-Rail TDIs don't get the mileage of the VE TDI's from the early 2000's is the emissions equipment. The Common Rail engine uses a particulate filter. Every once in awhile, fuel is injected during the exhaust stroke to burn the particulates. That fuel goes against your fuel economy.
I've had diesel fuel gel twice, neither on the TDI. My old Rabbit Diesel had gel problems in NV and CO. Both times it was well below 0. Most of the time the stations know to treat the fuel. Sometimes they don't get to it in time.
The two major reasons for higher diesel prices in the winter are anti-gel additives and demand for home-heating oil. Generally the price of diesel drops in the summertime to approximately the cost of RUG.
When it comes time to buy a new car, I will definitely get another TDI. No question. I won't even consider a hybrid. More power, less complexity, better driving characteristics, etc.
I hope more car companies consider diesel for the USA. We really need to increase fuel mileage across the board or get off oil completely. Diesels would be a huge help in that regard.
edit: The big reason there hasn't been a diesel hybrid is cost. A Golf TDI-hybrid would start at $30K. Would you pay $30K for a compact hatchback? Even if it did get 60mpg?

Holy smoke what is with all the bitching in this thread?
Final Cut X is coming! It seems to have all the stuff i'm dying for.. maybe even CUDA support! Damn now I got to sell my CS5 production suite..
And yeah if you want you can still use iMovie and feel good about it. I know enough people who got a great result out of it because they did not get stuck with tech they didn't understand. All these opinions about personal choices is a total waste of time.
Rejoice the choice and do something creative with all this energy
(FCP is rendering so I have time to waste lol...)

How does your vision plan to implement any non-steering games on the big screen? You can either look at your iPad, or look at the television. There is a reason physical buttons are important for big screen gaming. Touch screen gaming will always suck for anything more than flinging birds into bricks.

As far as implementing new tech to enhance the gaming experience, I'm perfectly happy to leave it it Apple and their partners. I'm pretty sure they've got it all planned out (and easily paid for) for the next 2-3 years.
Apple has this weird habit of continuing to develop the landmark products they release. Shocking, I know.

Apple is totally a lone player in this market of HDD-based high capacity MP3 player. The only thing prohibiting me from nabbing one of these is the highly scratchable chrome back. If Apple goes with full unibody aluminum enclosure, I'll nab one for sure.
Seriously? The only reason that you haven't picked up a high-capacity iPod is because you might scratch the back side? :confused:

There are several companies that have been working on various ways to provide power without cords "the holy grail" being the eventual elimination of power cords for all sorts of computers, applicances etc.
My guess is that they will have a 'basic' version of this workable for a low power mac laptop that can be powered in a room with a wireless power transmitter doing away with the need for a power cord. As long as you are within range, similar to a wireless signal, the mac air will be able to charge and receive power wirelessly.
You heard it hear first.

As I'm sure others have noted, this jus seems less efficient than CMD-delete. I suppose more options are good, and I get this is a transition towards a more pervasive touch interface, but for computers with physical keyboards, this leaves me cold.
I always wanted a CMD-delete action for Dashboard; this seems like a step back.

I disagree, take the price of a mini, add a good 17" monitor (4:3 (but not a super cheap one)) then compare the price to the 17" iMac. Not much difference and the iMac has better everything.
true ,but you could get dual monitors slightly cheaper... oh wait no graphics card, yeah what is up with the mini? it should be the coolest piece of hardware, but it has gotten no love. wheres all the love ?:p

You are very selective with your figures- both the French and Italians also have carriers in position, the US didn't send all but two of the missiles. The French sent the first planes in and as far as I know are the only nation to have engaged Libyan planes.
Like I said, about 50% of the planes involved are US. Which makes sense as the US has a bigger airforce than France/UK (and the rest of the coalition) which is what you would expect from a country with many more people!
Perhaps it us you that doesnt like the fact that the US isn't the only real player here? The US, France or UK could do this whole thing alone- it isn't that big an operation! Or perhaps, as firestarter points out, you don't like the idea of US working as NATO currently headed by a Canadian?
This is a true coalition with all sorts of countires involved, and we should be happy about that.
All I'm saying is that behind the scenes when you look at the facts, there's a different story and you can't take everything at face value...and you should know that about politicians too. I think some of you are "glad" that it's finally not purely lead by the US and this is like some "dream team" thing. But I'm just afraid that you are just in denial. :cool:

Weird... While the NAND flash/cache would be nifty, it's hardly a feature I would consider to be vital. FW800 and DL DVD writer on the 15" MBP are much more worthy causes. ...I doubt we'll get those features either. :( You won't see NAND with this update - probably not until spring/summer '07.

goddamn i can't make a joke on these forums. i was kidding dude. it's not a choice, if it were a choice it would have been a fad that went away years ago. Some people are naturally attracted to the same sex, and not just people, homosexuality has been demonstrated in animals as well. Some brains are just wired differently, and to deny them rights for it is just not fair.
I don't believe any was born gay, that's my opinion. I believe you make the choice in your life, just like you make the choice on what career you want and college you desire to go to. I have friends that were once married (guy/girl) and then divorced because they liked their sex better. So now they are openly gay and happy. I have back and forth e-mails with them stating they consider it a choice. One of my friends is a writer for Lesbians and spoke in front of congress on this issue 2 years ago. I was with her and she even stated that it was a choice to become a lesbian and it's now America's choice to accept it for all for choose this path.

One question about 512MB vs 1 & 2 GB mod bandwidth. If the Mac comes with two 512MB mods installed in Riser A and I buy two 2GB modules to put into Riser B - total 5GB, will the slower bandwidth (or whatever it's called) of the two 512MB mods slowing down the faster 2GB mods be offset by having RAM installed in both risers rather than pulling the 512's and only having two 2GB mods installed in Riser A only - total 4GB? The difference of 1GB of RAM doesn't seem like that part would matter if the 512 mods slow everything down.
The bandwidth of DIMMs doesn't really change with their capacity (assuming their timings are the same). It is the number of active channels that gives you the increase in memory bandwidth.
I believe the memory controller will interleave the lower 512MB (since you have a branch populated with 512MB) of each DIMM resulting in full bandwidth access (4 channels) to that range of memory (512 x 4 = 2 GB) with the remainder of the 2 GB DIMMs (the remaining 3 GB) only getting the benefit of a single branch (two channels).
Personally I wouldn't purchase 2 GB DIMMs given their extra cost in relation to two 1 GB DIMMs... in other words use more of the memory slots you have ... unless you really want to leave room to add more RAM later.

The chance that the iPod Classic is updated to 220GB is zero. Apple has no plans to ever update a hard drive based non-touch portable device (they would not waste their time), and they've shown even less interest in increasing the capacity of any device beyond even 64GB flash.

You wanna know WHY they haven't gone past 64GB Flash? It's too damn expensive still....Sucks they can't bump the iPhone up to 64GB, although there are rumors to a 64GB iPhone5....we can only hope
