That really depends on the program, on how "parallelizable" the application is.
The simplest way to think of it is like this: Let's say you have a program that first has to calculate A. Then, when it's done that, it uses the result of A to calculate B. Then, when it's done that, uses the result of B to calculate C, then C to D, and so on. That's a *serial* problem there. The calculation of B can't begin until A is done, so it doesn't matter how many processors you have running, all computation is held up on one spot.
On the other hand, let's say you have an application that needs to calculate A, B, C and D, but those four values are not dependent on each other at all. In that case, you can use four processors at the same time, to calculate all four values at the same time.
Think of it like baking a cake. You can't start putting on the icing until the cake is done baking. And you can't start baking the cake until the ingredients are all mixed together. But you can have people simultaneously getting out and measuring the ingredients.
So that problem is partially parallelizable, but the majority of its workload is a serial process.
Some software applications, just by their very nature, will never be able to do anything useful with multiple processors.
This is true, but there are still many many ways to optimize the multi-core processor that's not currently being use.
For example, I am waiting for a program to compile right now. Although I have a dual core on my computer, the compiler only compile one file at a time and usually takes about 10 min to do a full compile . If I have an 8 core computer with a multi-threaded compiler then I can cut the total time to jsut over a min + couple of seconds for linking time.
I think the main problem with muti-threading program is that it is difficult to implement, especially for coders who only knows high-level languages. Muti-threading in low-level program such as C is not easy but at least it is straight-forward. But trying to muti-thread high-level language such as VB or C# can get you into a big headace since everything is abstracted from the programmer. To do that, you need to get into unsafe code and call a bunch of DLLs, and it's easy to get memory leaks. Basically it can start to get very complicated, very quickly.

i may add some more over the break
nice. i doubt i'll add anymore over the break. i'm about at my limit i think
Cool, you are getting away from me again... but that's a good thing! :p
yep, a good thing for sure. we are doing better as a team for real now. just gotta keep people interested and involved

But, look at it from the other angle. If Vista and Leopard does not look all that different, why switch to a Mac? Tiger would be a bit more user friendly to maintain, iLife might end up being less buggy, but you gotta balance that againts the "fear of the unknown", repurchasing some of your software and lack of close friends etc. to "borrow" software from. I am not that upbeat about 2007 for OSX.
MS is functioning with BG for the FIRST TIME, they have lost their IDOL their reason for being -- will they go insane :confused:
WHAT is the historical precedence for this :confused: :confused:
Lets see Japan lost their GOD, their king after WW2, replaced him with MacArthur who rebuilt their industry, but for a long time THEY JUST COPIED AMERICAN GOODS even though they had newer equipment.
HHHMMM !!! Could this mean the MS will collapse because they spent their best years copying everything tech !?!?!?!?
NO ! I think they will emerge eventually as a new company, BUT FIRST THEY WILL HAVE TO QUIT COMPUTERS !!
A new company that builds all things based on thar XBox.
And things won't work out until they jettison Balmer :D

Manual (stick) shift cars are rare today and I'm wondering how many people still know how to drive them. How did you learn and do you have a desire to own one?
Rare? are you serious? please leave America and see how rare they are ;)
I learnt how to drive a Manual from the get go, my licence allows for both Auto and Manual cars :cool: Jealous? :p

There is a reason that some of us Jailbreak, outside of the desire to add applications outside of the appstore.
Apple hackers develop better jailbreaks now so they can keep up with the superior system Android has.
There's so much more one can do with Android.
After having every iPhone, I tried Android and I'm so amazed at their great capabilities.
Android is awesome.
That said my Iphone 4 is best as an iPod replacement.
I have the best of both worlds.

the last few generations of the jetta have been absolute rubbish ... i hoping this new generation is actually better
I started a thread about the new Passat and Jetta a little while back. Basically, the new Jetta is bigger, costs less, and uses cheaper materials. People expecting Golf-like levels of refinement and build quality will be disappointed.

I don't think that apple should be in the business of approving apps.
I think they should do their best to categorize them and create methods to protect certain age groups from accessing inappropriate apps.
But otherwise get out of the business of approving 'this' while denying 'that'.
Agreed. This should not be available to minors. That should be the only restriction.

If Apple does an "unlocked" phone (meaning, the kind of phone that used to be the rule, not the exception, which wasn't locked to a specific service provider) you'll be able to use it on Verizon (of course, assuming it supports Verizon's connection mechanism, which is different from Sprint or Cingular, but most of the phone manufacturers out there have no problem with this).
I thought Verizon and Sprint used the same network type (CDMA)...?

Amen to that. I give this about as much credibility as an apple rumor scrawled in sharpie on a gas station toilet stall.
Huh? What happened there? Didn't Think Secret used to be the place to go for the most accurate rumors? I definitely trust macrumors and appleinsider a lot more than think secret now though.

I thought this the minute the thing was demonstrated - it'll be a whole lot more than they showed, and it'll look a whole lot different too, methinks. :)

guys i think you're being too hard on zune. play with one. it's not THAT bad. it's ugly, but the interface isn't bad at all. I don't plan on buying a zune (my ipod is fine and i'm waiting on a video pod), but it's good to have it in the marketplace for competition sake. maybe apple will actually pay attention to some of the features like the built in radio tuner which is a nobrainer...
I played with it in a Target over the weekend. It IS THAT bad. I agree with the competition aspect, but the the things comes off clunky and akward...

All I'm saying is that behind the scenes when you look at the facts, there's a different story and you can't take everything at face value...and you should know that about politicians too. I think some of you are "glad" that it's finally not purely lead by the US and this is like some "dream team" thing. But I'm just afraid that you are just in denial. :cool:What exactly are you trying to say? Iraq was a US war of choice, and Bush was fortunate to have an equally vainglorious partner-in-crime in Blair or he'd never have been able politically to do it. Afghanistan was also a US thing. Why would anybody else take a lead in those? Libya was a UN thing, and on Europe's border, so naturally the impetus came from Europe, and Europe is taking proportionately much more of the load.
Next you'll be saying that the US won WW1 and WW2.

Im really looking forwards to this, if the 8-core 2.66 Macpro its going to cost just a little more than a quad 3ghz Macpro, im going to be buying as soon as it hits the website...
As a recent Mac switcher, coming straight in with a base spec macpro(4x2.66/4gb/1750gbHDD), im now happy to invest in a more powerful machine.
My only concern is the heat... my current Macpro runs 24/7 and 95% of the time is at full load across all 4 cores... and its still silent with temps never going over 52c... will these quad core chips run much hotter, meaning the front fans have to spin faster/noisier to keep the machine cool?Maybe. If Apple goes from the 80 Watt 3GHz Woody to the 120 Watt 2.66GHz Clovertown then definitely. But if Apple chooses to only offer the 80 Watt 2.33GHz Dual Clovertown, then perhaps not and we'll all be happier campers. Or perhaps Apple has other cooling schemes in mind to keep a 2.66GHz set of Clovertowns quiet via other ways. Given that the Logic board stays the same, I'd rather buy the 2.33GHz version.

I'm just wondering if this is a more thorough way of deleting the app. Like, taking out app support and preferences unlike when you just drag the app into the trash. Does this simply move it to the trash or does it take care of everything in the background?
I think it is basically making 2 ways to delete an app, which I suppose will be more "user friendly" for people coming to Mac from the iDevices halo. But again, wondering if this actually cleans the apps crap up.

I just remembered why I stopped reading LoopRumors about 2 years ago. They flip-flopped between two states: 1) Weeks and weeks of "We'll have news real soon now" and 2) outrageous claims that were apparently totally made up as clickbait.
I guess things haven't changed over there. I might check again next year.

Keeping weight down is all-important. Which is why I remain in love with the Lotus Elise. It proves that less weight fixes everything - better handling, acceleration, braking, fuel economy...of course in a hybrid, the battery pack is always the vexed question. Even the best batteries are still expensive and relatively heavy.
But even the Elise isn't immune, it's all relative of course, but it's gained roughly 170kg since the Series 1. :eek:
But along with aerodynamics... it's perhaps the most important factor in, as you say... handling, acceleration, braking, fuel economy... pretty much everything.
When you think how innovative a car like the Audi A2 was, I do find the lack of real progress over the last 12 years particularly sad. 10 years ago, the A2 was a sub 1000kg (sub 900kg in certain trim) proper 4 seater, its 3 cylinder TDI engine could easily achieve 70+mpg imp without even trying (according to Wiki 107.8 mpg & 140 mpg imp were also achieved).
The 1.2 TDI version emitted 81g/km CO2, featured Stop/Start, an Eco mode that disengaged the clutch when the accelerator was released to maximise free wheeling and was rated at 94mpg.
And this was 10 years ago...
In many ways, it's shameful today that we think that 60 or even 70mpg is somehow remarkable for a family car. :(
the Cruze diesel, which may be able to equal or exceed the new Jetta TDI's level of equipment, refinement and pricepoint.
But not the brand image... that could perhaps be the biggest stumbling block of all, it certainly is in Europe anyway.
Personally... I don't think GM have a clue, and that's one of the reasons why they got themselves into one almighty hell of a mess, and only time will tell if they can get themselves out of it. I'm still of the opinion that GM's decision to attempt to introduce Chevrolet into the European market will ultimately prove futile.
Here in the US, the sedan (saloon) is king, even on smaller cars like the Focus and Corolla. That is slowly beginning to change, but Americans still like three-box cars over hatchbacks. Personally I prefer hatchbacks and wagons, though larger cars still look good as sedans.
Have to say my preference is for saloons... occasionally an estate (particularly A4 & A6 allroads, also 159 Sportwagons, that sort of thing), hatches (the bigger ones anyway) & estates can/tend to be a little boomy in my experience. Saloons also often have better body rigidity too.
