How much more 'blind' do you want it? All the programmer has to do at this point is use multiple threads. Even if they don't, multiple cores will be automatically used for system and other processes.
Splitting one thread so that it ran cocurent with itself is a recipie for massive trouble. Mac OS X is about as blind as any system out there for the programmer. There may be some more optimizations that the system could make in it's own handling of multiprocessing, but from a programmer's perspective it doesn't matter how many cores the system has. (Unless you really want it to.)
Programming in pthreads is a bear (at least to me) an easier method would be nice. However, when I was looking up something today I came across OpenMP (http://www.openmp.org/) which seems to greatly simply setting up threads and the like. I suppose I was just thinking of run-time parallelization.

Not likely to happen.
Maybe, maybe not. Fact remains that the liquid-cooling in the G5 Quad is very complex beast. And more complex things get, the more likely they are to break.
There are minimal to no reports of problems with the Quad G5 cooling system. I've run 3 of these for nearly 9 months with no problems.
A whole 9 months? Those systems are supposed to last for years.

It's going to come down to the experience, and the experience is in the apps.
Developers aren't going to create applications for the Android, unless people buy them, people are not going to buy Android tablets unless there are applications. The same thing with RIM.

Expect new Merom-based macs, and a new iPod, on September 18th.
Simple. Apples' current sale for students on getting a MAJOR discount on iPods when you buy a new mac, ends on Friday the 15th. Thus, the following monday, will come the new updates. They wouldn't release before, because they would be cutting their profits even more than they are now.
Not true.
Recent years, updates came right before the end of the promotion.

Hey everybody the Big News is
NBC Today Show went High Definition today!The Today show is an embarrassment. The US major tv networks do not have any real morning news programs. How to trim your dog's ears and an inside look into American Idol contestants is NOT NEWS. It is an entertainment talk show.My post of this news has nothing to do with content. It is a historic moment in the evolution of television. If you don't think so, then you are paying way too much attention to the content and not enough to the process by which they are conveying that content.

These things don't travel very fast.
I was having a look on Google and a container ship only takes 20 days or so to get from China to Europe, and a military ship would be faster - so you don't need that much time to get ships into place.
And China to Europe by ship is a long way (http://www.gcmap.com/mapui?P=hkg-sin-trv-dxb-cai-gib-sou&MS=wls&DU=km).

What is the present smartphone marketshare?
For Q1/11 aprox. 15% for Apple.
Q4/10 numbers were:

Again: Apple sold 3 million more devices in Q4/10 than they did in Q3/10 (16 million compared to 13 million in total numbers) but they lost 0.7% marketshare in that 3 month (Q3/10: 16.7% marketshare, see first graph, Q4/10: 16.0%, see above).

Well I for one was kind of disappointed. Leopard is sort of Apple's chance to prove they can out-Vista Vista, and I'm not really sure what we saw today does it. I've been following Vista somewhat closely, and it really does catch Windows up to OS X in terms of features and prettiness.
I really think most of the features shown off today are already present in Windows (I've definitely heard about all of them before) or will be in Vista, and it's too bad Apple didn't have anything truly innovative to show us. Hopefully those secret features are something good...
The other thing that has me a little concerned is the huge amount of Vista-bashing that went on. I feel like if Leopard at this point were truly better than Vista, they'd be silent about Vista entirely and let the new system speak for itself. That would be really slick. That's not what happened however, and instead there was a lot of "look what Vista copied from us" and "check out how much better Leopard is." What I saw today, though, makes the former statement sound whiney and the latter sound foolish, since in my eyes, in terms of features, they're about on-par with each other.
I really hope Apple pulls it together. They've got to do this right, because come next year, most of the myriad reasons for switching to a Mac will be nullified by Vista.
BTW: whoever this "Platform Experience" guy is, get him off the stage and go back to Steve.
hmmm, most of the features are already in windows? what version of windows do you have? are you from the future? and, ummm, who knows what's going to be in vista because it keeps changing...even what you see now may not make the final cut. to say that the two OSs are the same because they both have the same features is akin to saying that a yugo and a mercedes are both the same because they both have four wheels and an engine. look, there are things that vista will have that osx will lack...there are things in osx that vista will lack. neither os will be perfect. still, os x is great because of its underlying architecture and not only b/c of this feature or that feature.
and most people will not be making their buying decision on which os is better...the greater selling point on the mac is boot camp and booting windows on the mac. most people aren't going to care what os is better.

Does anyone seriously believe games today will show any significant improvement on a Mac Pro?
1. The video cards are underclocked compared to their PC equivalents on the Mac.
2. Generally, you are limited to a framerate of 60Hz anyway.
3. Most games are old ports, and need to run thru Rosetta.
When playing a game on a PC, you have DirectX to take full advantage of the hardware, and your processor is usually tagged consuming any and all cycles it can for the game. On a Mac, multithreading, and sharing the processor among apps seems to be the flow of the computing experience.
I'd predict a single Core2 Duo Extreme would still outdo a dual processor 3.0 Ghz Xeon Mac Pro when memory timings are nearly half of the Xeon on the Core2.
Bootcamp???

Amazing to see how most Democrats are willing to lie to themselves and ignore the hypocritical truth all around them... the leftist side of the antiwar movement is all but gone, but not because the policies have changed, only because the man has changed.

How does that Nobel Peace Prize taste now? Hopey? Changey?

Well, I had been screwed about 4x as much as a typical cell user... at least when I had the misfortune and poor sense to have a Cingular contract.
I think there are several people who have felt "screwed" by their wireless company, regardless of which company they chose to sign with. I have used Cingular from day one of my cell usage, and I have nothing but good things to say about their service. Of course, you're 4x more likely to get screwed, I guess. ;)

'lets make a tablet for our business users, to get serious workloads done. we can call it the playbook'.
i didn't know charlie sheen was in charge of their team?
If you watch and listen to Rim's co-leaders, you see the resemblance to Charlie Sheen. I'm all for company's fluffing their feathers and believing in the products they market and sell, but these guys come off as being sooo Charlie Sheen. Their grasp of reality is lacking to the point of making them sound ridiculous. I'm surprised investors don't punish them more for this - but of course many Wall Streeters still use BB's, so it makes sense.
Change is tough for lots of people and companies - which keeps Rim going and will at the same time be the death of them.

I am a new Mac owner. I just bought my new 20 " iMac and I am learing aout the upcomming conference and possible new product releases. I
Would appreciate any thoughts on my question.
I am considering returning the new 20" I just bought in the 14 day period and taking the 10% hit and waitning to see if the iMac gets updated and I will repurchase. What is the likelyhood that the version I have will be updated. I would be bummed if I just bought it and I am at the end of a cycle. The $160 fee would actuallly be worth it to me to get thte latest. I would have to return it prior to the conference to stay within the 14 days but i may not want to loose out on lthe chance to get the latest.
Any thoughts on this 20 " model be increased with a new processor??
Thanks,
New Mac owner.....merk850
dont take it back.
I dont think that the difference will be that much, with the new systems.
If your happy with its performance then keep it.
A mild CPU boost isnt all that, and I doubt that the video cards will be upped that much.
I wouldnt take the hit in money lost, cause you can always sell it later down the line and get the lastest and greatest thats really a must buy.I respectfully disagree. I say take it back and be ready for a much faster iMac Core 2 Duo. You want the latest, take it back. It won't be the latest for many more weeks. Core 2 Duo will be the latest for two more years.

Oh, and here's one I just ran into that reminds me:
Is it so much to ask to have it go to and from the background cleanly? Christ in a cartoon, you'd think backgrounding the application is a huge exercise in resource allocation by how long it takes to bring back all the windows sometimes, if they reappear at all. FCP is bad enough about this sometimes, but Compressor is even worse.
Minor, sure, but annoying as hell.

While I would also like to know why, I'm not sure this is a big deal as it seems to me that the remedy to going to be very simple: a) encryption is on by default, and/or b) flushing the database after, say, six months.
Oh I agree, it's not as big a deal as some are making it out to be.
I would still like to know the "why" part. If anything just to satisfy my own curiosity.

Probably, but it was certainly orchestrated to look anything but. Sarkozy was very obliging in shooting his mouth off, as was Cameron. It may have just been luck, but if so it was a remarkable piece of luck to have 4 submarines, a flagship-capable surface ship and all necessary support in the right place at the right time. These things don't travel very fast.
