Please explain - I have no idea what "that" is....
---
Regardless of the tool, however, it is usually much better to let the OS dynamically schedule threads across the cores. Unless the programmer has some reason to try to control this, the alternative is some resources (CPUs) being overcommitted, while other CPUs are idle.
It doesn't matter who has the better tools - it's usually better to let the OS decide microsecond by microsecond how best to schedule the CPUs, than to have the developer make those decisions at edit time.
I've used the SetProcessAffinityMask APIs fairly often, but it's always been for specific test or benchmark situations. I have a hard time thinking of a situation where a general application would want to statically control the scheduler - it's just "bad think" to even try. (Except for those weird-a$$ NUMA Opterons - you can be really scr3wed if you have to go through HyperTransport to get to memory. I check NUMA topology, and use affinity to keep the AMD architecture from killing me.)
I've owned SMP machines in the past and often found it more useful to force CPU affinity of CPU-heavy tasks to a single processor, as Windows 2000 (which was current at the time) by default had a habit of swapping it between chips, resulting in a lot of cache-dirtying. I think it was the load balancing code, but it's been a while now and I don't have those machines handy currently. However, you could see some significant improvement in processing time on some non-parallelizable cpu-bound tasks.
I've no idea if MacOS does this, but at least in the case of Core 2 it shouldn't matter anywhere near as much, as the L2 is fully shared.

Creative is only worth $500 million, how come Apple didn't just buy them?
Because... then you will have to beef-up the reclycling program to get rid of Creative's garbage products... the clean up process will cost more than the big bucks that Apple is paying now.

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.

And what does that have to do with the app store trademark? He doesn't mention "app store" does he?
No mention of App store. I was just watching the video recently and found it interesting.

Respond strongly? You mean defend yourself?
Samsung has almost no chance of winning against apple in this lawsuit in phone design/UI and etc.
Samsung clearly copied apple. Samsung phones were nothing like Galaxy S phones until iPhone came out in 2007.
Samsung did copy apple. They are about to lose billions of dollars on this one.

Let me see... wars in Iraq, Afghanistan, Libya... high unemployment in the USA. Cost of energy is killing the average guy in the pocketbook. I know... lets spend our time getting those terrible DUI apps out of the app store... that way we can tell our Constituents what a great job we are doing representing them in Washington.

Don't forget to vote (them out).
Just writing a letter. Not a whole lot of time involved there, I'd think. Presumably a Senator can author something like this during the same week that they tackle more "legitimate" issues.

Exactly. Which is why the Ghz myth will stay for a long time. You can't market Memory or FSB or SATA or PCI-X/PCI-E, you won't get anywhere.
Ghz, GB, "X times faster", and you can play games that look very pretty. Those will be what computer marketing will be all about for many years to come.Yeah, the GHz made sense to me until AMD started pulling this XXXX+ naming. Then I realized it. It worked pretty much until Intel gave up on clock speed is the THING when it comes to computing power.
I didn't buy a new computer between 1999 - 2003 so I had a lot of catching up to do.

Shucks-another iOS/iPhone rumour!:p

Hopefully DWI checkpoints yield such low benefits from these apps that they become extinct although I doubt it. Hassling thousands of honest, sober citizens to catch the 1-2% legally intoxicated drivers isn't worth the price we all pay. I question our freedom in America each time I drive up to a checkpoint. If you're wondering, no I've never received a DWI nor driven intoxicated and I still hate these checkpoints. They don't make me feel safer on the road.

To those clamoring for a matte option I feel your pain but our time is long gone. I bought a Mac Pro just so I could use matte screen because my underdeveloped eyes couldn't get used to "looking past reflections" on the new iMac (which I sold in less than a year)
Perhaps not though. Apple dropped the matte display on the Macbook Pro only to bring it back again.
I know more than a few people who find the reflection issue horrendous, and in my opinion it goes against the PRO "user-experience" in exchange for the consumer "user-experience" Apple is so proud of, meaning brighter, more saturated colors.
Apple even puts fake reflections in their ads.

Let's face it, many people are already regularly downloading movies by nefarious means, and are perfectly happy waiting a couple of days to obtain a ~700mb file over the course of a few days.
All Apple need to do is apply the same logic as they did to music, to movies. The situation is identical. People will pay for faster download times, previews, wider selections and peace of mind. You could easily get a movie into a good-enough-quality video file of around 800mb-1gb - sure, not VIDEO_TS quality, which is why they'd have to be a bit cheaper than retail DVDs. But it'd work, I know as a film maniac I'd use it pretty regularly.
It may rely on a few extra things though. Let's say, a video iPod with a big capacity, maybe a new video file format (.avi is perfect but Apple obviously don't dig it) and IT HAS TO BE SAID bigger godamn hard drives in Apple portables.
Even with a video iPod, a Movie Store is going to interest lappy users perhaps most of all, and the current 60gb standards in MacBook just doesn't cut it for ****.

Because they use the same battery, how can videos play longer and not music?
Either the video playback code was improved to be less power hungry (maybe it uses less CPU, maybe it doesn't need to spin the disk as much), or an improved video chip was put in which uses less power.

At this price point and with these features - they may push even more customers away from the mac pro and towards the iMac. Even for some pretty heavy lifting, it's going to be a beast of a machine.
I can say from experience that the i7 SB is a wonderful CPU. It competes with or beats the top end 6 core processors in apps that are not heavily multi-threaded.
It's pretty nice that those dell 30 inchers are almost exactly the same size as the iMac.
Absolutely. If going Mac Pro route you still need 3 ACD's. Going iMac route you just need two ACD's. I still doubt I will need the power of i7 for my PHP/MySQL coding but I will take it. :)

google seems to just keep giving me results that say either:
"send it to <insert generic dodgy address here> and i will unlock it"
"you can't do it"
"you need an SPC code from the carrier."
"you need a null cable"
my point is. you cant just walk into a SonyEricsson (or nokia, etc) store, buy a phone and say "im going to use this on xyz CDMA carrier"
I thought you wanted the greatest honest to goodness top of the line phone! Why would you want to keep your old phone if you switch to a new carrier?

I thought the 5G was already able to handle 640x480 movies, just couldn't display them at full resolution?
The way I understood, it was capable of playin that resolution in mp4, but not when using AVC/H.264...

you have no idea of the speed and the damage that can be done.
A smash move like that can cause a car to spin and then start rolling and can cause major injury to even death.
Good luck tracking my actual identity down. And also good luck getting anything you dug up admitted in court, because there is absolutely nothing legal about introducing any evidence of my identity you found by tying this account back to my IP/ISP without a warrant.

hmm you think that is so hard....
Your ethics are beyond pathetic. You are showing that you care about no one but yourself.
You clearly are showing that your limit is legal but even then you clearly only follow the laws you like. Legally and ethical are not the same thing.
You need to work on your ethics. I hope and pray you never get into any position requires ethicical decision. That means you should never be a manager, an engineer, lawyer or a doctor as you clearly do not have ethics. Mind you most lawyers have no ethics which might explain the problem with out legally system.

Ultra compact computer arrangement Apple Patent Filing - Looks Like Cube II (http://www.electronista.com/articles/06/09/08/new.apple.cube.patent/)
Hope this isn't old news for everyone; this is my first post, although I've been following the forums ever since I started thinking about replacing my old Powerbook (should finally have the money by next month!).Excellent find and an award worthy first post. Thank you very much and welcome to the forums.What about the patent designs that were just shown of the Cube 2?
From Unwired View - Apple Cube reborn (http://www.unwiredview.com/2006/09/07/apple-cube-ii-computer/)This is very encouraging. Perhaps this is what Steve has to talk about on Tuesday. I am a Cube lover - still own two.
