I heard Leo Laporte talking about this on his KFI podcast... exciting... one question... how many softwares take advantage of multi cores? I understand that the OS can deal with it for multi tasking, but how many programs multi thread?
DD
Unfortunately not many multithreaded apps - yet. For a long time most of the multi-threaded apps were just a select few pro level things. 3D/Visualization software, CAD, database systems, etc.. Those of us who had multiprocessor systems bought them because we had a specific software in mind or group of software applications that could take advantage of multiple processors. As current CPU manufacturing processes started hitting a wall right around the 3GHz mark, chip makers started to transition to multiple CPU cores to boost power - makes sense. Software developers have been lazy for years, just riding the wave of ever-increasing MHz. Now the multi-core CPUs are here and the software is behind as many applications need to have serious re-writes done in order to take advantage of multiple processors. Intel tried to get a jump on this with their HT (Hyper Threading) implementation that essentially simulated dual-cores on a CPU by way of two virtual CPUs. Software developers didn't exactly jump on this and warm up to it. But I also don't think the software industry truly believed that CPUs would go multi-core on a mass scale so fast... Intel and AMD both said they would, don't know why the software industry doubted. Intel and AMD are uncommonly good about telling the truth about upcoming products. Both will be shipping quad-core CPU offerings by year's end.

Why? What are the advantages/disadvantages to having it higher or lower in the case? Does the weight distribution matter?
Weight is one - ever try picking up something that's top heavy? It's rather awkward to carry/pickup and makes it much more likely to tip. Another reason being the cord would likely be hanging down from said spot - while this seems ok it's really not good for the wires inside - ideally it would only have sweeping curves in the line as opposed to what happens with havinga plug so high. I'm conflicted about the heat issue as there are pro's and con's to both configs so I'll stick with awkward weight distribution as the key limiting factor.

This will likely suck, because the interconnect Intel is using is just too damn slow. Putting four cores in the same package will just make the situation worse, because a lot of applications are significantly limited by memory performance.
The Woodcrest processors have been put through their paces pretty well on the supercomputing lists, and their Achille's heal is the memory subsystem. Current generation AMD Opterons still clearly outscale Woodcrest in real-world memory bandwidth with only two cores. Unless Intel pulls a rabbit out of their hat with their memory architecture issues when the quad core is released, AMDs quad core is going to embarrass them because of the memory bottleneck. And AMD is already starting to work on upgrading their already markedly superior memory architecture.
In two years' time, Intel will release Nehalem its next micro-architecture - to replace Merom/Conroe/Woodcrest. It is supposed to ditch the FSB in favour of Intel's own interconnect, named CSI. Two years after Nehalem will come another micro-architecture.
In some respects, I'm quite happy to have ordered a Woodcrest Mac Pro, especially if the slow FSB does slow things down when Woodcrest's successor is released. If the Mac Pro can last me three or four years, I'll be in time for the post-Nehalem generation, which should be fairly spectacular.

im using snow leopard, will all my documents and apps gone if i upgrade to lion ?
PowerPC (Rosetta) emulation is no longer offered. That means if you have any PowerPC applications they won't be able to run in Mac OS X Lion. You can determine if you are still running PowerPC applications by going into Applications -> Utilities -> System Profiler -> Applications and viewing "By Kind". This will show you which applications you have that are running under PowerPC. Rosetta had already become an optional install in Snow Leopard, and it appears Apple will be removing support for it entirely in Lion.

A same-sex attracted person is living a "gay lifestyle" when he or she dates people of the same sex, "marries" people of the same sex, has same-sex sex, or does any combination of these things. I think that if same-sex attracted people are going to live together, they need to do that as though they were siblings, not as sex partners. In my opinion, they should have purely platonic, nonsexual relationships with one another.
Heterosexual couples need to reserve sex for opposite-sex monogamous marriage. If I had a girlfriend, I might kiss her. But I wouldn't do that to deliberately arouse either of us. If either of us felt tempted to have sex with each other, the kissing would stop right away. I know of a woman who gave an excellent answer when men asked her why saved sex for marriage. She said, "I"m worth waiting for." She lived by her Catholic convictions, and she wouldn't risk letting any man use her as a mere object, as a mere "sex machine."

and i got an HTC INspire for $20 that is better than my old 3GS

You know, Sony and Nintendo are just *SO* behind the curve with next gen gaming systems.
Microsoft has had it's XBox 360 out for MONTHS, while Sony and Nintendo gamers are lagging behind, barely able to function on their PS2s and GameCubes.
If Sony and Nintendo don't release the PS3 and Wii, respectively, in the next week, they'll be the laughing stocks of the industry. There's no excuse for them to release their next gen gaming systems a year after their competitor.
I'm going to hold my breath until I turn blue if I don't get what I want, because I'm childish like that.
Although Sony's PS3 is an overpriced beast with BlueRay support, the nex Nintendo console (which can play old school games) seems promising. As for the Core 2 Duo, personally I don't really care one bit when it comes to a "consumer" grade laptop. Any 64-bit software will work on a 32-bit platform, so I'm fine. Leopard is backwards compatible, so great! If the Merom chips are more energy efficient, that seems promising, but my fridge and TV consume more power, so I don't care. Presently Dell does offer core 2 duo processing chips, but only in their $2,500-3,000 laptop systems. I'm still looking around for laptops that range around low-end MBP and MB prices that have C2D and I haven't found any yet. But since the XPS systems have Core 2 Duo installed, I'm sure the first macs notebooks to see them will be the pros first. But seeing as how my macbooks is presently in the shop for random shut down syndrome, I'm more concerned with a working machine than a machine with a slight efficiency advantage.

bibbz,
Phew!
You are doing all of us a great service here with this information.
The salesman just called me from the store I was in today.
He is telling me that there is no guarantee of the iPhone even
if you get the pin -- but he admitted he was not certain. All he
knew was that there was something like 9500 pins nationwide.
Told him that I had just read your message and that you were
saying if I got a PIN I have a guarantee of a phone.
He warned me that Radio Shack does not want the word
"guarantee" used.
I am putting a lot of faith in what you are saying here.
I will be at my Radio Shack store early tomorrow.
What?!
No white phone?
Can you verify bibbz?
The info i stated is directly from my DM.
We havent been told no white ones. I even asked specifically on the call, and no one had heard that.

The iPhone is voluntary. You enabled location services.
Did you read ANY of the news articles.
With location services turned off, this data was still be collected. And Apple says this was a "bug"
So you're wrong.

I bet you that you'll never see a iPad with screen resolution like 2048x1536, it's a ****ing nightmare to iOS developers. You don't understand that it's ****ing crazy, iOS interface like MacOS X interface is not scalable. Apple have to change the whole GUI before making this step forward.
what did Apple do with the iP4? Oh wait...
As far as Devs are concerned, they 2x the res for their ease. Sorry, its not that "****ing crazy". Oh, and before someone says "well theres not going to be a mobile GPU that could handle that res"; not true, even now theres some great emerging technologies that have handled concurrent instances of 1080p (like 10 displays)...much less whats going to be available in 2012(if we survive the world ending:) Furthermore, native apps like iBooks/iTunes/etc dont require heavy processing to display hi res. Sorry man, youre wrong.
PS: Take it easy on the *

Does this mean I should cancel my order on the 11" Mac Book Air 1.4GZ, I got it with 4GB ram and it's a refurb so I saved some cash. Should I wait until June.
Thanks in advance for your advise!!

My advice: sure; why not wait.

Is that irony?
I'm also a student, and I don't think I could wait any longer than a month for these long-overdue MacBook Pros to ship... so a possible late November arrival is worrying to say the least.
I'll tell you what irony is...spending all your time making commercials that tout your products cutting edge over the lame PC's while steadily showing how truly behind you really are.
Try concentrating on the products instead of the gimmicks...
As for me, they have 2 more weeks of my patience before I revert back to my PC days. I'm tired of getting made fun of by my PC Geek friends while I play on my outdated G4 PB.
I'm beginning to believe my friends when they say that Apple pats their own backs for crap that PC makers created a year ago.

On the server side.
The server/desktop division with Windows - as with OS X - is one of marketing, not software. Windows "Workstation" and Windows "Server" use the same codebase.
Couldn't be farther from the truth. I have no problem with Microsoft or Windows, evident by the fact that I've ran their operating systems for the last 10 years. I have a problem with all the crap they're putting in Vista, but otherwise - Win2k and XP Pro have left me primarily trouble-free.
Well, if you can't find evidence of Windows running on well on machine with >2 processors, or of the significant low-level changes Microsoft have made to ensure it does, you aren't looking very hard.
Similarly, if you're one of the "Vista is just XP with a fancy skin" crowd, you've obviously not done much research. The changes in Vista are on par with the scale of changes Apple made to NeXT to get OS X.

It makes total sense to hold back the units for the following reason:
Day 1: Someone calls up BestBuy to find out if they have the iPad2. They reply, "yes we have a very small amount in stock". Customer arrives at the store and they are all sold out but they are told that there will be a few more on sale tomorrow. Customer picks up some random crap like a DVD, mouse or whatever.
Day 2: Customer arrives at the store and they are all sold out but they are told that there will be a few more on sale tomorrow. Customer maybe picks up some other random crap and leaves.
Day 3: [Same as Day 2]
Day 4: [Same as Day 3] etc...
If you just release a few each day, customers will keep coming back in hope of finding one and possibly buy some other small items while in the store. If you sell them all out and have nothing for weeks, you will have no customers coming to the store. BB knows that the iPad2 is in short supply and that they will have no trouble shifting the stock if they need to so they are happy to sit on it and keep a steady flow of customers coming through the store.

Do you mean Vista Premium compliance? I'm pretty sure I've seen "Ready for Vista" stickers on plenty of current notebooks featuring GMA950 graphics, for example.
And btw, I have to say "good job" to Apple for doing whatever was necessary to avoid having to put a bunch of goofy decals on their computers. The most amazing thing to me is the number of PC notebook users that leave all those stickers on (I've even seen some people leave the "features" stickers on).
Yeah i never got that either. First thing i do is scrape them off even if i have to use a knife
