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.

I'm actually surprised this doesn't happen more often. Applestores must be filled with cash. I would think one would be a bit easier to rob than a bank.
I would bet there is actually very little cash in the typical Apple store. I personally have never observed a single customer pay with cash for anything at the two stores in my area. Everybody pays with credit or debit cards.
These guys were after the products, probably iPhones and iPads, which would bring in some hefty cash on the black market.

hoping for apple te thin the screen bezel. Also hope the main build will have no optical drive. but will make it optional. I do not need one, some do.
for all those crying for an optical drive. buy an external one. i bet most of you guys will benefit more of having an SSD+HDD instead of one of either with an optical drive.
next year i expect, slight resolution bump. hi-res option becomes standard. Lighter/ not thinner design. A better ventilation. hopefully 2 thunderbolt ports (instead of FW800) but only if we have advanced enough with converters from TB.
I do not expect usb3 i think apple will never, as they do with bluray. And as most of you are already very unpleased with this. The future is digital. Within 5 years 2K movies can be downloaded in minutes and also streamed. as far as usb3 apple will sell thier special Thunderbolt to USB3 converter for $30.

It just occurred to me, that in Leopard iChat has a thing called Remote Desktop Express. This could easily be used in the new device to send Front Row to the TV!
Apple, I'm sure is thinking ahead. Or they plan on releasing the new iChat on the 12th.

Steve Jobs knew this was a BS patent and it shows in his comments. Absolutely Stupid. Hell, the LISA had a Hierarchal File System. I'm still angry that this patent was even granted in the first place.
Bottom line: Creative knew this was a BS patent, too, but they figured they had to try. However, when the patent was granted to them, they had a weapon in their war against the iPod. Rather than concentrate on making a better product, they used this weapon as a way to get some quick cash. They bet on Apple settling and not going to court.
In the meantime, MS comes in and announces Zune, which threatens other WMA compatible players like Creative's offerings. Creative now thinks they need a backup plan and decides that during the negotiations with Apple, they can get them to give them a license to produce iPod-approved products. Now they have a fallback incase their own offerings fizzle out.
The question is: Will they go after Microsoft, too? It would be hypocritical not to, after all.

If you compare their investment in R&D to what they manage to churn out, it's pretty sad.
Microsoft doesn't really play in the consumer / gadget / toy market, which simply means that you don't get to see most of their products unless you work in a corporate data center. And unlike Apple, Microsoft -has- data center / server products that people WANT to use and that are years ahead of the pack (Sharepoint Portal Server, Exchange Server, SQL Server, Terminal Services, just to name a few) - and a LOT of their RD goes there.
Also, nobody here should kid themselves - Microsoft still OWNS the desktop and office suite markets. Around a BILLION computers run their software, and even most Macs are dead in the water without Microsoft Office and/or Microsoft Windows (in Boot Camp, Parallels, Fusion, VirtualBox).
So Apple was more profitable in the last quarter. Big deal. Somebody with enough time on their hands might want to analyze the spending behavior and amount of staff and level of salaries to find out -WHY- that was the case. Maybe the guys at Microsoft have higher salaries and more vacation. Maybe Ballmer put more money into RD and marketing than in the last quarter. Maybe they bought more startups than before.
Actually, who cares. Both companies are extremely profitable, but Microsoft has been profitable for a couple of decades more than Apple (who almost died in the 1990s while Microsoft was making more money than anybody else).

I had to have a good laugh following the greenpeace links from the macrumors article.
* the "making waves" site had a pic and an article stating "our volunteers outside weere handing out real organic green apples". Only thing is the apples in the picture are red!
*what are greenpeace more upset about...? the fact that there are tonnes of electronic waste in a garbage dump? or the fact that there are hundreds of poor and underpriviledged kids running around the dump collecting the waste in order to survive? I am sure that by fixing Apple's problems they will remove these kids from the dump! What is supposed to be in a garbage dump....the waste or the scavaging kids?

Yeah it should be, there's no hard drive to make noise and unless you keep it on a stove or do insanely heavy processing you shouldn't hear the fan either.
Sandy Bridge should also run more efficiently than the C2D. That will not only extend baterry life, but it will also keep the normal operation temperatures down.
My only worry is how much I will notice the loss GPU compare to the 320M.

Typically you get an upgrade and no price change. Sometimes the price even goes down.

Apple may offer a choice of Core Duo 1 or Core Duo 2 as a BTO option.
Doing this might allow Apple to sell the Basic MacBooks and iMacs for less while
the Core Duo 2 models will be favored by those who can afford to spend a bit more.

But why should it? This isn't Motorola... this is Apple. They are supposed to be the masters of industrial design and software integration. No doubt the phone will have an awesome user interface, but I expect more from Apple than sticking an antenna and GSM chip inside a nano, putting a keypad underneath it, and calling it a day. This couldn't have taken very long to dream up... it seems like the most obvious and un-Apple idea of them all.
If this is the fabled iPhone then Apple is losing its touch... the design was already done when they introduced the nano.
I hope Apple wants this to be a phone with iPod functionality opposed to a nano with phone functionallity. The difference is huge. What is the primary function of this device? To play music or use as a phone? Thus far it looks like a nano with a software update and a GSM chip sadly.
that's just it.. if it is an ipod/iphone.. any phone with a slide out keyboard, which apparently is getting to be popular.. and has a limited number of buttons ALWAYS available.. then on the iPHone those limited buttons are created using the iPod clickwheel.. so for me, I think it could be brilliant. ANd by now we all know how to use the clickwheel, without even looking at it.

Oh god no I hope apple doesn't cave to this kind of Orwellian garbage. I feel for all of the victims of DUIs and know that I have personally called the police on a car that was very obviously had an impaired person behind the wheel but as a non drunk driver if I want to avoid being hassled I should be able to.
First of all, DUI checkpoints aren't so frequent that they provide every day hassle to drivers...secondly, they take a very short amount of time to go through (if you havnt been drinking, Cops know). Besides, how is this Orwellian at all? Apple isn't being asked to report users of the application or anything. Sorry man, but if it saves 1 life from drunk driving...it's the right thing to do.

Of course, they've never really cared if people get offended, even their own voice actors (Issac Hayes).
Hayes has issues... He stuck with the show and helped Matt and Trey and the folks at Commedy Central poke fun at every race and religion... And then came the Scientologists turn to get made fun of. Hayes, being a Scientologist, didn't agree with that (even though it's OK with him to defile every other religion), so he announced he was leaving the show.
Oh, and the Mr. & Mrs. Tennorman chili was classic. Cartman rules. ;)

This would be sweet! I definitely wouldn't mind switching to Cingular and their rollover minutes. Looking at Cingular's family plans it looks like I would save about $20/month over my current T-Mobile plan. And since Cingular is GSM like T-Mobile, my mom (who I share the plan with) could continue using her existing simple Samsung mobile phone that she's familiar and comfortable with (I'd just have to get a Cingular SIM card). And as someone already mentioned above, phone numbers in the US are transferrable between carriers, so although it's probably a pain I would do all the paperwork to transfer the 2 numbers I have under T-Mobile.
I just hope the phone is sweet enough to make me wanna ditch my already impressive Sony Ericsson phone. The main improvents I would be looking for over my SE phone are:
- Better music player software/controls (I think this one's a safe bet)
- Stereo bluetooth (less sure about this one)
- 3G enabled (looks promising - I'm hoping the iPhone will be 3.5G HSDPA enabled like the LG CU500 phone)
- Better browser (Actually Opera mini is fine, maybe all that's needed is a larger screen and faster connection speed)
- Better camera, especially under low light conditions (almost guaranteed to be better camera based on rumors it's 3 megapixels and also Apples experience integrating tiny video cameras into its laptops and iMacs)
- Larger screen (would like it to be 2+ inches diagonal and at least 320 x 240 pixels) (this one I think is a safe bet)
So basically, I will almost certainly be getting the iPhone as soon as it's available and I fill out the paperwork to transfer my number over...
Hey everybody,
So often I hear people talk about how great the customer service is for Verizon, Cingular, and Sprint. Why are all of you in need of customer service with these companies? I'm with T Mobile and have never needed to call and straighten a bill out, or get credit applied to my account. I'd say the best customer service is the kind you don't need to use. So, I'm hoping that T Mobile will carry the iPhone 6 months after the initial release.
Lucky you. I have T-Mobile and I've definitely had reason to call them. I thought their customer service was excellent (better than Verizon or AT&T), but I still wouldn't say that their service is "so good you never need to call them up".

Thunderbolt will never replace USB because they serve different functions. You will never see low-bandwidth devices such as keyboard/mice/USB stick using thunderbolt because it doesn't make sense.
The real question that I haven't seen anyone ask, is will this be Intel only or will other chipsets/manufacturers support it as well.
Also I don't know if anyone mentioned it but one of the reasons Firewire never took off was because of royalty fees that need to be paid for implementing it. Thunderbolt has no royalties on it and this should help drive adoption.
From the looks of it Thunderbolt will be able to replace eSata, Firewire, and maybe Expresscards.

Some people have already mentioned AirFoil for audio, and there's AirView for video.
Airfoil still needs the Airfoil installed on your computer to work, it won't run with just the iOS apps. I think pika2000 is asking about iOS apps that emulate an airport express, so that you could send the same audio to every device in your house.

Well unless a non-glossy screen is an option I won't be getting one.
In fact until they do my current Core 2 Duo iMac will be my last Apple - period.
I don't need my computer to also double as a mirror.
And no, I don't want a mini, or a laptop, and I can't afford a Pro.
Umm, ok. :rolleyes:

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.
