I came to the opposite conclusion....
Running many compute-bound single-threaded benchmarks and apps - I saw how NT (pre Win2k) would balance across CPUs (that is, a "100%" compute-bound job would show each CPU running at 50%).
However, setting affinity so that one CPU was 100% and the other was 0% had no significant effect on the run times. (And by "significant" I mean statistically significant - I literally ran hundreds of runs in each configuration.)\\
By the way, with Win2k3 (and XP 64-bit, really the same system) you see much less "balancing" - a single-threaded app will stick to a CPU for much longer.
I suspect if any observable difference occurs depends upon the application, dataset, etc.
I'm guessing the 50% "balanced" method was done to try and keep a single CPU from heating up too much, and with the advent of multicore systems, it probably no longer matters which core is generating the heat due to them being in a single package.
It could also be MS found that certain circumstances (like mine) resulted in improvements in processing.
Interesting stuff.

I'm right with you when you say "that some of us want the power of a desktop but dont have the budget for the xeon range." Also I dont like all in one solutions. However, the 24" might be apple's way of saying that's close enough.
I agree with you (and I realize I'm preaching to the choir here) but I would argue that in some ways, a 24" AIO is even worse than a 17"/20" AIO, due to the sizable (no pun intended) investment in the display. If your 17" iMac bites the big one, but the display is still fine, well, okay, you have to throw away a perfectly good 17" display. But they're fairly cheap these days, so whatever. However, what if something goes a year or so from now on your 24" iMac? For me at least, throwing away a perfectly good, high quality 24" display would really suck. :cool:

Anyway an odd thin about airplay is the ability to stream just the sound from a video file in itunes. It can't be done but it can be done from iOS.

Unfortunately, cats are known liars.
They're purposely getting our hopes up just to let us down. It weakens us. Humbles us. After hearing no announcements tomorrow all we will do is sulk around, giving us more time to give them more dried food.
They're still pissed about the MagSafe connector... that ruined things for them.

Can't wait! But I will have to. Now we're getting this close and the rumours are starting - there's no way I would ever buy a new iMac until the update. If my current one breaks then the real waiting game begins.

Face it the Conroe Mac is coming.
iMac 24" - $1999
Mac Pro (downgraded to 2.0 Ghz) + 23" - 3198
That is a $1k price gap.
A high quality midtower would fit perfectly. They have another chip to differentiate the product matrix. It is coming!
Mac Mini - Core Duo (yonah) - base entry machine. 2 RAM slots
iMac - Core 2 Duo (Merom) - All in one basic to prosumer models, quiet operation and powerful. 2 RAM Slots
"Mac" - Core 2 Duo (Conroe) - mini tower 1 optical, 2 drives, 2 PCIe, 4 RAM Slots - prosumer to low end workstation.
Mac Pro - Xeon (Woodcrest) - Full tower 2 processors, 8 RAM slots, 4 PCIe, 2 optical, 4 drive bays. - Mid to high end workstation.
Face it Apple left the biggest gap between the iMac and the Pro machine ever! There was no crippled tower to span the distance between the two. Apple wants to expand market share. They have a power processor that will not step on the toes of the machine above or below. Why wouldn't they use it. Before all the desktops ran the G5. It was difficult to provide product differentiation without gobbling sales up internally. Here the highest end Conroe cannot match the lowest end dual Woodcrest at highly threaded apps. This is a win-win situation. It will either come out on Tuesday or another special event in early october.

can't stand balmer, and I love my Apple stuff, but we need a strong Microsoft, and they've just been soooooo lame the last (what?) 5 years? maybe 8 years?
It would be a darn shame if they dwindled away to nothing. They need new leadership.

Windows is as easy to use as SL. I'd say in terms of functionality Windows beats SL hands down. But most Apple fans idea of functionality in Windows is complexity and they prefer the dumbed down Mac operating system.
When I start using Mac OS X 2 years ago, it took me two solid months to get used to its ways. I can tell you, when I started out, I would not have described Apple's operating system as easy to use. Now I'm competent using two operating systems, and can appreciate the strengths and weaknesses of both. Neither are very difficult to use if you apply yourself to learning, but you have to put in the time to take full advantage of either one of them.
Well put :)

I'm amazed that no-one is seeing the very dangerous path we could be heading down here. Will people only see it when it's too late?
Are we looking into the jaws of the future where you pay, but never OWN anything? Music, Movies, Apps.
You pay to have the right to listen/watch/use the data.
The data is never downloaded to your device to do as you wish, it's always held by the owners. or distributors.
I can see this coming like a flashing red warning sign.
what are you going to do with your downloaded song? if you still use cd's, you're an old timer when it comes to technology. My wife and i both listen to pandora/itunes music in the car and hooked up wirelessly throughout the house. Boom, all the music in the cloud service could be right there right now. Instead of having to go to my computer, sync what music i want so i can load up my phone with music i want for my trip.
Times are changing. Once this cloud service is the standard, you won't have to have multiple hard drives with your data or music/photos. Go look at dropbox and how popular that is. There is no need for users to have mass amaount of storage when you can access it in the cloud.

New Ipods .... that's kool .....
New video movie store .... good !!!
We need some new MBP AND MB !!!
These cpus need an update really bad ... compared to what is goin to come out with the other pd competitors in two weeks with the C2D
I saw on a shope u can get an C2D Labtop for 856 bucks !!??!!!
that is pretty scary since the MB is more expensive and got Core Duos !!! :confused:

Probably, but it might depend on whether you can download the Windows 7 drivers from ATI, or whether you have to use Apple's dual boot drivers.
Your question should be "can TBolt 'team' two channels for double bandwidth on one connection"?
For your question, the answer is "yes" if you can have two simultaneous 10 Gb/sec links. For my version, the answer is yes if you can have one 20 Gb/sec link.
Shipping sometime this summer - so the answer is "no, there are no TBolt devices available to buy".
The real worry about this fact, though, is that no Apples have been tested with openly purchased TBolt peripherals. I wonder how many software updates, firmware revisions, or motherboard replacements will be needed before TBolt devices work reliably without kernel panics.
I wouldnt worry about kernal panics or incompatibility issues with thunderbolt. Its like any other peripherals, its been heavily tested by apple and as long as other devices meets the requirements for thunderbolt, there will be no issues.

Ah, classic manipulation of an idea. At no point in that post did I say "helping people" is a bad thing, or that it should never be done. Quite the contrary... I actually said:
So please, don't cherrypick. Education is the only answer to this problem, nobody disputes that. But to say there is absolutely no correlation between the death and suffering going on in Africa, and a large portion of that society which is beyond help and beyond the limitations of education would be naive.
There are times in human history when, despite all our better efforts, nature is going to run its course, and those groups who have not adapted their lifestlye and way of thinking are left behind. I'm certainly not saying don't try, nor am I saying that saving even a single life wouldn't be worth the effort. I'm merely saying that Africa's problems are deeper than education. There's a culture there that has been in place a lot longer than even our own system of education and medicine has existed. To think that we can change that by giving them some condoms, explaining how they work and why it's important, is foolish. I'm saying that Africa will sort out it's own problems in time, when those individuals who recognize the problem for themselves get a voice. We can help, and every little bit helps, but it's not ours to fix. This is FAR FAR more complex and rooted than a kid who hurts his knee on a skateboard.
AMEN brotha!

Apple is the copyright holder of those images and they provide the right to use those images in Applications running on macs via the API on a Mac running OS X.
So why can't you use an official Apple API on the iPhone? That's crazy.

You are wrong. CDMA is also in SK and Japan. Most 3G users in Japan are on CDMA2000 a varient of CDMA that is used in the U.S.
I meant on a 2G level; I wanted to make things simple so that he/she could understand. And don't forget about the popular W-CDMA technologies, such as UMTS/HSPDA which is used by Cingular and soon T-Mobile in the US.
And Japan's 2G PDC technology is by the way TDMA based and not CDMA! Although their 3G technologies I believe are CDMA based.

i wouldnt be suprised, apple is heading for the same thing they did with mac vs pc battle. they are 1 company, that means they can be VERY succesfull with introducing new products but in the end they cant keep up when the other companys throw in their overdrive. just watch not with duelcore android phones. coming halv a year before "iphone 5" if thats even gonne get released. android or wp7 is going to be the dominant mobile operating system withing a few years cause they arent closed systems.

Depends on the cipher really. Not all ciphers can be decrypted with even the latest of the latest hardware, especially if you lack the private key. And a court order can force you all you want to give up that private key, but they can't force you to remember it or not lose it. ;)
"I don't remember" or "I lost the private key to my encrypted backup, but here's the AES-256 encrypted file guys, have a go at it" are perfectly good answers.
Over in the UK not remembering passwords can sometimes land you in prison. Just remove the incriminating files frequently and regularly.

Could someone please clarify, are we expecting the MacBook Pro to be updated at WWDC? I'm ready to purchase a MacBook Pro right away, but if we are fairly certain that there will be a new release in August I will wait as my current laptop is doing the job.
Does anyone want to give some odds? I know that no-one can be certain but for instance for a 25% chance I'll wait, for a 5% chance I'll just order one now.
I wouldn't give you good odds for WWDC, but you should have your update within less than a month from it.
Merom isn't out at the time of WWDC- it won't be until later in August. It is possible they may let apple take pre-orders if steve wants to really make it a massive attack at WWDC on all parts of the line charging ahead into the next generation, but you never know with him.
Of course the way things are going, for all we know there may really be PB G5s at WWDC, who knows nowadays :rolleyes:

Amazing! I totally agree, I don't mind paying higher taxes here for better services and better rights.
I know someone who works in the public sector was told to get his working hours down because he was working more than the amount he was supposed to by law in his job. Was told to get it down to 42 hours a week I think.
Guess that would never happen on your side of the pond!
About 30 years ago, his holiness Ronald Reagan fired over 11 thousand Air Traffic Controllers (http://en.wikipedia.org/wiki/Professional_Air_Traffic_Controllers_Organization_(1968)) for going on strike. One of their most important demands was for a 32 hour week, so that they would not be falling asleep on the job.
Today, a bunch of the scabs he hired to replace those controllers are retiring, putting a great deal of pressure on the system. If nothing else, I think the 32 hour week is a good idea if you like flying and arriving safely. Sadly, Reagan's firm stand has left us in a perilous situation, with controllers snoring in the tower and planes landing without help. So the NTSB's solution is to require that they get at least 9 hours between shifts, which I think is pretty scary.
Most of us would prefer these guys fresh and alert. All we need is one impressive crash (that will be blamed on this president) to get this issue really pushed to the forefront � which will probably result in a controller getting fired and no real improvement to the system.
Welcome to America, take a moment to find out where the nearest emergency exit it, bearing in mind that it might be behind you.
