Do you have a reference showing that this translates to better performance in real-world application tests in a head to head competition?
Not handy, since a lot of this happened on mailing lists.
The short version is that the memory performance scales in a very sub-linear fashion as a function of the number of cores being used, whereas Opteron scalability is almost linear up to a large number of cores. The good news is that for single dual-core processors the memory performance is on par with dual-core Opterons and their in-cache performance can be better. The bad news is that this performance does not hold as you scale cores in a system. So for some applications (e.g. those that live mostly in cache) the Woodcrest processors will be mildly faster than Opterons, but for most the performance is about even in real app benchmarks.
I've seen fairly comprehensive benchmarks for both databases and scientific computing applications, both of which thoroughly exercise the memory subsystem. Even though a single Intel core theoretically has more bandwidth, the high latency means that the real bandwidth is about the same as the slower Opterons (which have real bandwidth that approaches theoretical) and the cross-sectional bandwidth of Opterons when you get up to 4 cores and higher is much higher since the scaling is almost linear with the number of cores. For Intel, I think it was the case that a bigger cache was a cheaper design choice than a truly scalable memory subsystem. As a result, they will have different competencies. Some types of floating point codes should run very well on Intel.

There's something I don't get. Doesn't DVD SP allow you to author non-commercial (non-DRMed) bluray discs, with the same feature set as DVDs (but in HD)?
If it does, that should be good enough for many. I doubt that the big houses that produce commercial DVDs (Warner, Sony, etc), use Adobe Encore for their titles anyway... They likely use high end solutions from another league entirely.

If Samsung had left it as vanilla Android they would've had a day one sale from me. Touchwiz is an abortion of programming. It's horrendous.
I'll wait to see how easily vanilla ROMs can be ported over or if it winds up being the epic clusterf**k that the Galaxy S was. Couldn't get rid of Touchwiz even if you tried. Using a different launcher and it still ran in the background eating resources. Remove it entirely? The thing kernel panicked and rebooted in an endless loop.
Samsung still doesn't get it. VANILLA Android. You want to offer your own launcher and apps as an alternative? Great. Offer them in the marketplace or from your website. Otherwise take your Touchwiz, and your ridiculous RFS file format and cram it up your mother's box. That whole software department at Samsung just needs to be exterminated.
Christ I am so sick of them taking fantastic hardware and absolutely ruining it by using proprietary file formats and frankenstein versions of Android. I do get a kick out of their 10.1" model being both thinner and lighter than the 9.7" Ipad2 though. That will undoubtedly have the apple apologists out en masse.

Really what sort of clients ?
Some people do more than use Final Cut for making YouTube videos. FYI. :rolleyes:
Yup I know especially considering I have nearly 12 years in broadcast TV delivering to every major channel in both the UK and US.

Why does no one ever mention the Dock? It is a HUGE part of OS X and hasn't changed since Jaguar. It could be so much more useful if it allowed for dividers, more customization, etc. I hope the Top Secret stuff includes major improvements to Finder, the Dock, and Expose.

I'm not a birther. But I would love to know why the certificate looks new when the president is nearly 50. Now I'm about five months older than he, my original birth certificate has faded. The certificate he produced clearly isn't the original. Or if it is the original, it's astoundingly well-preserved.
He hasn't been carrying this around for 50 years. Did you actually read the article?
The White House also released a letter from the president on April 22 requesting two certified copies of his original certificate of live birth. Also released was a letter from Loretta Fuddy, Hawaii's director of health, approving the request.
The president's personal counsel, Judith Corley, traveled to Hawaii to pick up the documents and carried them back to Washington on a plane. The documents arrived at the White House around 5 p.m. Tuesday.

Zooming on Safari is pretty nice too, not as nice as the iPad's scrolling, but still nice.

i HATE the new zooming, drives my nuts and works "best" using a finger of both hands.
and i never understood spaces, can't figure out what it does lol

Funny, I'm a Dallas Cowboy fan, the fans are fanatics and everyone who is not a Dallas fan HATES the Cowboys. I feel the same heat being an Apple fanatic. The fans are loyal and defending of the brand while every other tech fan hates us. I need a big white Apple logo with a blue Dallas Cowboy star in it. I might be shot!!!! lol
Dallas fans will criticize the Cowboys if they play poorly. Apple fanboys will not. It's not like being a fan, it's like being indoctrinated, with no real vested interest. It make no sense whatsover.

So the interesting fact is:
Verizon iPhone release didn't help Apple to stop losing marketshare although everyone said the deal will quadruple iPhone sales. :rolleyes:
iPhone Q1/11: 19 million (+ 2.5 million)
Android Q1/11: 38 million (+8 million)
Ouch. No wonder they are now sueing HTC and Samsung. If you can't beat them in the market, beat them in court. Apple must have learned that from Nokia (like they learned the choppy animations when you start third party apps in iOS 4.3.2 from Symbian).
iPhone: 4% of market, 50% of profit
http://tech.fortune.cnn.com/2010/10/30/iphone-4-of-market-50-of-profit/
So whats the point of market share if you're not making any money?

I've built a gaming PC around the Core 2 Duo E6700. I'd like to be able to install OS X on it, because the only reason why I'd ever use Windows is for the latest games. Here are the spec's, think this would run OS X nicely? ;-)
For $599 you can buy a MacMini with a Core Solo processor. That is currently the cheapest way to get a legal copy of MacOS X for Intel. It is clearly illegal to install that copy of MacOS X on your home-built computer while it is still on the Macintosh, it is unclear whether it is legal or illegal to install it if you removed it from the Macintosh (seems legal in many european countries). If it is legal, then obviously you can also salvage parts for the MacMini, like DVD drive, harddisk, a bit of memory and save a bit of money that way. Unfortunately an unmodified MacOS X will refuse to run on anything that is not a Macintosh.
You may be able to get MacOS X slightly cheaper by buying a refurbished MacMini, or by buying one on eBay. And sometimes people sell broken computers on eBay.

First off, before the ignorant attacks begin, no I'm not a birther. I'm personally of the opinion that he was born in America and generally share the president's feelings that this is a giant waste of time.
Now... to the issue at hand: I'm not an expert in layout/graphic-design, but can someone please tell me why the PDF Certificate of Live Birth has Illustrator layers? If it's a scan, shouldn't it just be a single image, jpg, pdf, png, etc. consisting of a bunch of pixels and not layers? I downloaded the file from whitehouse.gov, opened it in Adobe Illustrator, and after releasing the layers slide the black text around seperate from the green/white background. I'm not sure what's going on here, can someone shed some light on the issue?
I'm assuming there's a logical explanation, any graphic artists here want to update the rest of us?

Maybe the certificate is legitimate, but I think the original short form would have been more convincing than a pristine copy of the long one. I like Obama, but I loathe his extreme liberalism.
No public health coverage, extending mideast wars, extending corporate tax cuts and Bush tax rates in general, actually lowering taxes in general to a historic low, supporting and campaigning for conservative democrats like Blanche Lincoln, Arlen Spector, etc., cabinet filled with big corporate players, didn't fight for serious Wall St. reform, didn't fight for second stimulus, dragging feet on gay rights and civil rights in general.
Where's the extremism?

I really really really hope they just go in with a carrier on this (of course requiring Cingular to not cripple the functionality). There's no way in the world Apple would make as much money off of this as if they got in with one of the big guys. Just ask Disney - ESPN mobile is bombing as is Disney mobile. It doesn't work. And most of those you have to pay retail price for the phone - screw that. I'm going to be with Cingular anyway I might as well get them to take $200 off the phone for me.
PLEASE STEVE, GO WITH CINGULAR!!!!!!!
Note; I'm just saying Cingular since they are the only ones who really seem interested in offering iTunes on their phones...
