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.
OK, I'm hardly a programmer (PHP doesn't really count) but that's the exact same description that I've heard applied to the description of what it takes to vectorize a program (i.e. make it Alti-Vec optimized) [that and the process of making loops that can be unrolled]. So I've got to ask, is there some difference between those two concepts? If not, it sure seems like we would have a lot more multi-core enabled apps out there already...

October 23rd, 2011 is the iPod's 10th birthday. I bet they will release a version this fall to commemorate it, if not a special edition of some kind. Maybe they'll let Jony do what he did with the 20th anniversary macintosh and make an $8,000 iPod with an OLED display and graphine processor just because they can.

Amazon is not a generic term. It is, however, the name of a single river on planet Earth...among a few other names/uses ("the Amazon", "Amazon basin", "Amazon Women").
Where else have you seen/heard the term Amazon in a generic sense? Some examples of a generic term are (at least have been generic over the past 75+ years):
light bulb
door
wood
lock
Add
Windows,
Words
besides others !!

Absolutely. Although I've met many dozens of gay men in my life who, no matter what you plied them with, couldn't and wouldn't have sex with a woman. Can't say the same about a sizeable proportion of allegedly straight men.
Can't disagree with that analysis.
There are a hell of a lot of "straight" guys who are in the closet at least as far as being bisexual.

am i the only one who doesn't think the name is as awful as people think? :D
in any event, i doubt that's the name. granted, apple doesn't register urls for individual products, i'd find it hard to believe that they'd leave this one in the wind for just anyone to snatch up.
in all likelihood it relates to some aspect of the features, or the overall weight of the device.
i really wish it was the fabled MacTablet being released, but it sounds like it's still a ways off...

Disappointed :(
Anyone know if it will be having a revision or if all of this was baseless dross, little more than hype?
Be patient. We'll probably see it in the next couple weeks, definitely by the end of the month.

I've never owned an automatic. I'm addicted to driving a sports car with a manual gearbox.
After owning several I simply cannot imagine anything else. I enjoy driving too much to drive an automatic sedan.

Money talks. A big ad campaign will produce much increased Zune sales.
And it's also true for Apple. Many people buy iPods because they have seen all of those TV ads and billboards, not because they did extensive comparison shopping.
Come to think of it, a good number of iPod purchasers are filling demands of their kids, who specifically plead for iPods. And kids are greatly influenced by advertising.

I could see this as a concern for politicians and celebrities whose locations might be used as fodder for tabloid gossip. Maybe a couple going through a divorce could use the data to substantiate an affair.

Perhaps if you spent more time educating yourself and less time convincing yourself that a flawed product is acceptable, you would learn something. Try googling the issue.
Based on the way you write, however, I am going to guess that you won't take the time to do so.
Some people are just not interested in facing the truth.
The way I write? This has anything to do with anything?
And again, the "evidence" you keep suggesting exists does not represent what is actually the case. Even within this thread, there are several people telling you they have no issues with their device. I don't have any issues either.
I hate to use the well known argument we often see on these forums, but you will almost always hear from the people who have issues with their products.
You will almost never see threads or comments from people that don't really have a reason to exclaim to the world that their device is perfect. Thus, we see an inflation of negative threads as compared to positive threads, and ignorant people take this to mean there is a wide-spread and critical flaw with all of the devices. Also, the negative comment is more distinctive, and thus more memorable than the positive one- again adding to the illusion you seem to be buying into.

15! *internet props*, at one point i had a blue and white g3, a ruby imac g3, and a few others...unfortunatly my mom was tired of all the "useless" (in her eyes) computers and made me discard them (the only computers i have every gotten rid of that werent compleatly dead)
now all im starting again, with this mdd g4 :D
haha - luckilly my family dont control my eBay account, and if they complain I find a way of hiding a few more of them in a cupboard (I actually ended up moving a shelf at one point so I could fit a iMac G3 in it) - although it is reaching the point where both my room and my dorm room are nearly full of old (and new) Macs... xD (All of them bar 1 boot, and the 1 that doesnt is only because its HD is on the way out - with a goodun it boots just fine).

If it can't support 4gigs of ram, it ain't worth the wait for me.:mad:
I've read that even the current MBP supports 4gigs.
Apple just doesn't offer it in their store since the CPU can only address around 3,2gigs (like every other 32bit cpu).

I wish there were more affordable Diesels in the States. A Cruze might be a bit "too" affordable, but neither can I step up to a Mercedes. The BMW 330d is sweet, though. I have to rule out VWs based on a personal bias. What to do... :o
The VW diesels are very well-built cars. A friend bought an '09 Jetta TDI and he is satisfied with it. I checked out the BMW 335d at the Detroit Auto show a year ago or so, and while I like the car BMW only offers it as a sedan and the base price is a laughably expensive $44k. If you won't buy a VW and want a newish diesel, your only other vaguely affordable option is a used W210/W211 (1996-2009) Mercedes Benz E-Class diesel. Nice cars, but you'll have to find one and it will be used (and not particularly cheap).
I currently have a 4.7L V8 Dodge Dakota. I'd buy a diesel version of it in a heartbeat. I could still get the power/hauling ability needed but have the mileage to justify having the pickup.
But now with the possibility of having $5/gal gas looming, the 18 HWY MPG may force my hand.
Had the truck for over 5 years, but it may get too cost prohibitive to keep.
that the US car makers still sells trucks, pickups etc. without diesel options is simply a complete lack of any common sense. diesel engines are practically made to be perfect for pulling and towing in commercial vehicles
Chrysler is particularly stupid in my opinion, because they should have put the Mercedes diesel engines from the Sprinter van (http://en.wikipedia.org/wiki/Dodge_Sprinter#North_America), which they were already selling here, into the Ram. The Sprinter came with four, five and six cylinder diesels that would fit into a variety of other vehicles, and would be particularly useful in trucks and SUVs. While weaker than the biggest V8s, they still offer a lot of torque for their size and much better fuel economy. Why, Chrysler? Why?
Mercedes sells the Sprinter here now, so the opportunity was lost for Chrysler.

Those speeds line up exactly with the T5000 series of Merom.And Yonah:
Intel T2400 Core Duo Yonah 1.83GHz 667MHz 2MB, Retail, BX80539T2400
Intel T2300 Core Duo Yonah 1.66Ghz 667MHz 2MB, Retail, BX80539T2300
Looks like the CPU speeds match onto Yonah parts too :rolleyes:That's why I'm thinking Apple is going to use indentical 32-bit Yonah speeds short term until Intel can keep up with Apple's Merom needs at a reduced price for the stop-gap short-term Yonah supplies. I'm thinking Intel will get caught up by November when Apple will quietly switch the mini assembly lines to Meroms. Almost a stealth switch except the packaging and docs will brag C2D on them.
This makes a lot of sense and adds immediate value to the mini line while Apple can't yet receive enough Merom processors to fulfill their short term needs while Intel is cranking up production. I think losing the single core mini is a huge big deal. Anyone who thinks they don't need two cores just doesn't have experience with that setup.
I think everyone here who is still on a single processor really can't understand why multi-core processing is so important because they don't know what it feels like. If they did, they would be on two or four already. Even the old Dual G4's are a huge advantage over the solos. :)

What do you think of this drive?
I have that drive in my mid-2010 MBP 15" 2.66, and I am impressed. 50 second cold boot to Outlook full load. App opening is fast, reopening the same app is almost instantaneous. You will take a slight hit in battery, I think less than 1/2 hour or so, but it was well worth it for me.
Avoid the temptation to restore from a backup (documents only), take the time to reinstall each app, and you will be delighted. I had plenty of time, and did it both ways, restore from time machine, and later app by app. If you have the time, app by app is much better, plus you can really look at what you have installed over time, and purge what you no longer use.
Well worth the $$! :D
