Dont bash his/her religious beliefs. They could be right or wrong...its up to each person to decide, and make true in their lives. Personally, I believe in a powerful God of love and grace. Just my 2cents:)

I don't believe in God. To me, I haven't seen anything to convince me of his existence and it just seems way too convenient of a way to explain away difficult questions. I also don't think that religion would add anything to my life - it's just not an issue for me, I don't even think about it until asked.
I am interested in this thread, just because I am not used to people questioning my viewpoint, or even really caring about how big the atheist population is. In the UK, it just doesn't seem that the issue is that important.
Is this a bigger issue in the US, and do atheists abroad feel pressure to at least consider the idea of a God?

Opinions should be the same. Nuclear is clean and efficient, but has potential dangers. Shouldn't take a meltdown to remind anyone of that.

Alex ant has made some good points on why Macs are a poor buy. They are so much slower and less stable then PC's these days according to everything I read. I still love my Mac, but since reading these message boards over the past year or so I have became more and more negative about Macs. Mac has lost the MHz war and are becoming slower and slower computers and has also lost out to XP for the best operating system, acording to so many people.
I am a consumer user, email, internet, MP3's, MS Word, digital camera photos, etc. I do like the iTunes, iPhoto, iMovie programs for what I do, but it sounds like with XP there is no longer any problems doing these things and they come loaded with programs that are just as easy to use. The sad thing as Apple was working on their switching campaign to switch people to Macs I am now considering switching to my first PC, because they have so much more megahertz and XP sounds so easy to use and stable.
Well I am broke right now so it will be next spring or summer until I buy a new computer, but as Mac has been going backwards on speed and their software is good, but not any better then Microsoft anymore I really should test out a new PC and see how it works for how I use a computer.

"10.45pm GMT: Now there are reports from nuclear plant operator Tepco that the Fukushima No 2 plant has lost cooling to three of its reactors.
So that's 2 reactors at #1 plant and 3 reactors at #2 plant? Chernobyl was only one reactor, wasn't it...
Fukushima Daiichi (No 1) plant
- has six reactors, three of which were shut down for maintainence. Two of the remaining reactors, Unit 1 has significant problems with a rising temperature and in another the operator says it has lost cooling ability.
– the Unit 1 reactor has seen radiation levels inside its control room rise, and slightly higher radiation levels have been detected outside the reactor. Pressure inside the reactor is twice the normal level, and the operator has been forced to vent radioactive vapor to relieve the pressure.
Fukushima Daini (No 2) plant
– has four reactors, and in units 1, 2 and 4 of them the operator has said it has lost cooling ability.
– Tepco says pressure is stable inside the reactors of the Daini plant but rising in the containment vessels.
The massive irony of nuclear power plants actually having no power to run their cooling systems. The backup diesel generators are flooded and the backup backup batteries are depleting. They are a power company after all, they should be able to find some spare batteries while they get the diesel generators back online.
Edit: Of course, you'd think an oil company would be able to cap off a leaking oil well...

The reason Apple "performs poorly" on recycling compared to Dell is that Apple computers, on average, remain in use approximately twice as long as Dell computers. Instead of being recycled, they are still being used. Apple does, after all, have a free recycling program. And there is no way that making computers that are replaced more frequently is more environmentally friendly.
It also seems that most of Greenpeace's complaints focus around Apple's refusal to provide Greenpeace with information on what materials are used in manufacturing its products.
Greenpeace does not have an exactly spotless record when it comes to ethics. Makes you wonder if it gets its computers from Dell at a discount.

This may be the case for say HP or Gateway , however Apple is Intel's new Darling and gets the best deal in the industry , so good infact that it prompted Dell to no longer feature Intel as it's exclusive chip vendor and as a resuld Dell will be introducing AMD based Desktops in August just to spite Intel for doing this.
Intel will give Apple volume-discounts. it does matter that do they order 100.000 CPU's or 800.000 CPU's
No matter how u configure a machine a Single CPU Woodcrest will never be as cost effiecient as a Conroe. Not to mention the need for ECC-ram , and expensive EPS12 PSU and Server Mobo.
Which is why I believe that macPro's will be all dual-duals. single Woodcrest makes no sense, and splitting MacPro-lineup between Woodcrest and Conroes doesn't make much sense either. Remember: MacPro's are hi-end workstations. so dual-dual makes sense there.

Apple does what they can to have more "enviornmentally-friendly" ways of processing their products. But 4th worst?
This is where I agree with you. I don't call myself a tree hugger. Sure, I love the earth and planet but sometimes people take it too far.

Even allowing for the possibility of a complete core meltdown (an unlikely event given the current situation, though not impossible), the structures were designed to contain such an event. The release of dangerous levels of radiation is extremely improbable, even given a situation significantly worse than that currently faced by Japan. Link (http://cosmiclog.msnbc.msn.com/_news/2011/03/14/6268351-clearing-up-nuclear-questions)
very informative link ... this is likely another 3 Mile situation and will get under control. The expanded evacuation seems to be added precaution and not an indication of Radiation sweeping the area.
I feel for the people that have been displaced and wish them well

It's a bit rich calling people delusional and then coming out with with wish list statements as if they're bound in volumes of 'The Future History of Smartphones vol ll'
The Android market has potential, but only for as long as lazy phone manufacturers, who have never learned how to do operating systems and software, are happy to grab a freebie. This situation is the same as you or me going to a fair and picking up a free dev copy of some new software... and then running a business off its capabilities. No license fee! That's the attraction.
The saved costs derived from having much lower in-house dev costs and shorter route to market make Android a gift. But not without major issues. CylonGlitch [above] makes this very valid point:
"... as many as 40 models of Android devices will ship, . . . "
"How the heck is a developer supposed to support that many different devices? Even if there were 5 different screen resolutions, it would be hard to optimize your app for each. Now different RAM configurations, different CPU's, different everything, OUCH."
It's a ludicrous state of affairs. A wet dream for the armchair geek maybe, but for the non geek buyer, the proposition is entirely different. It already gives me a headache just thinking about it.
With the iPhone, Apple have demonstrated one of the oldest marketing principles still holds true in the 21st Century. If you give people three models to choose from with two colour options, you make the proposition simpler.
But all other manufacturers are still depending on the old marketing model of offering a bewildering array of models to try and catch the entire market. Now, that model has failed already - because it doesn't work. The market is automatically diluted. So why are they still using it?
speedriff [also above] has decided Steve Jobs is a "douche" because he's being "hardheaded" over Flash, while "Other manufacturers are giving AMOLED screens and are getting better and better."
Apple make more profit from all their products than anyone else. One way they do this is by waiting until they can demand a very high proportion of a large enough production of a component [NAND flash memory, screens etc] at the most competitive price, or can manufacture in-house [CPUs]. That's not just good business, it's vital for long term survival.
Wait until June this year and we'll see the new iPhone with a longer [HD aspect ratio] OLED screen. And HTML5 is the future. in reality, Adobe are better candidates for the 'douche' epithet here. If Flash had fewer issues, maybe Apple would add it.
What you need to understand is that Apple is better at seeing, predicting and exploiting the WHOLE picture, than any other company in this game. And anyone who seriously thinks a disparate group of not for profit developers and a market full of lazy manufacturers with a 19th Century sales mentality are going to win this one, is simply not even looking at it properly.
You obviously have no formal education when it comes to the world of finance, so I'm not sure why you're even making comments about such things.
The simple fact that Apple has to make $23 billion more in revenue compared to Google, just so they can have $2.7 billion more in gross profit is nothing to brag about.
Go do more homework.

Use it to record your shows and then stream it to the iTV.
-bye bye comcast DVR.
what about calling it the iStream (ha)
Well.... not quite.
You see the ElGato stuff does not decode digital channels. Not only that, they can't even control your Comcast cable box to tell it to change the channel. So any channel that is digital (>125) you are going to have to manually change before recording.
Sound appealing? No, of course not.
This is the reason solutions like ElGato have not really caught on yet. Add a cable card system and its game over.

Fine - use the E6400 which is $224 in bulk or the E6600 which is $316 @ 2.6Ghz. The point is I would like an iMac without the LCD and all the other bells a whistles with a Graphics slot. If they can't do that for $1200 then Apple needs to pack up shop. Dell can do it for less than $1000 (Dual core 930 @ 3Ghz) so saying I'm willing to pay $200 in Apple tax is about as far as I'm willing to go.
930 is a netburst-CPU (P4) and those are absoluitely dirt-cheap these days, dual-core or not. Intel is basically donating them to OEM's these days. Not so with Conroe.
So Dell has a system with dirt-cheap CPU and that vaunted Dell-"designed" case for under $1000. And you are now expecting to get an Apple-system with kick-ass case and considerably more expensive CPU with just $200 extra?
That said, I would like to see a Apple minitower-system that uses the Conroe. It wont be as cheap as Dell, since whereas Dell might cut corners everywhere, Apple simply does not. Even their cheapest system (Mini for example) are very refined. Could you imagine an Apple-system that is made from cheap plastic (like this HP-system standing next to me)? I sure as hell can't.

As far as agnostics go, I know the difference between us and I couldn't care less....close enough in my eyes!!!! An atheist and an agnostic arguing to me is like hearing a Catholic and a Protestant argue....such a small difference in something so important.

You do recognize that there is not currently an HD system in place from Apple. If HD streaming does work, and I'm certainly not convinced of that at this point, you still have to shoehorn the entire system. The content you purchase from iTunes is not in HD and probably won't be for at least a year, probably 2-3. Therefore, the only HD content will be content that you added on your own, via 3rd party solutions.
So enjoy your patchwork HD system, I'd prefer something more seamless, and supported by Apple.
I am a video editor. All the content I shoot these days is High Def. My client's video is high def. The personal movies I take of my kids are high def. I edit them in either Final Cut Pro HD or iMovie HD. I use a dLink 550 now to stream high def to my 27 LCD monitor.
BlueRay disks are soon to be high def. The iTV will handle High Def via ethernet at least.
High Def Broadcasts exist right now in SLC.
Not sure where you are at with all this but I view a lot of high def content.

...but if a coal plant blows it's over soon, if a nuke plant blows it's over in 250 thousand years.
Where did you get that figure from? Cs-137 (one of the main long-lived dangerous compounds) has a half life of 30.1 years (http://en.wikipedia.org/wiki/Caesium-137).
Oh yes, and coal contains radioactive material too... which a power station handily sends up it's chimney for distribution in the environment!
A 1,000 MW coal-burning power plant could have an uncontrolled release of as much as 5.2 metric tons per year of uranium (containing 74 pounds (34 kg) of uranium-235) and 12.8 metric tons per year of thorium.
it is estimated that during 1982, US coal burning released 155 times as much uncontrolled radioactivity into the atmosphere as the Three Mile Island incident. It should also be noted that during normal operation, the effective dose equivalent from coal plants is 100 times that from nuclear plants.

It still does 200,000,000 calculations, but this time I'm multiplying ints.
Motorola 7455 G4@800Mhz: 9 seconds (Native)
IBM 750FX G3@700Mhz: 7 seconds (Native)
Intel P4@2600Mhz 2 seconds (Java)
PowerPC 7455 integer processing is consierabley better than floating point (obviously less work doing ints), but still less per cycle than the Pentium 4.
Very intresting the G4 looses both floating point and integer to the IBM chip, at a 100MHz clock disadvantage.
I'm still waiting to see that "better standard FPU" in the G4. It seems the G4 is absolutely useless unless you are fortunate to have vectorized (AltiVec) code.
Alex, yeah, the native version was compiled under 3.1. It really is interesting to note that despite the 750FX's 100MHz clock disadvantage, it is able to outperform it by 22%. Since there is a 13% difference in clock speed, and if clocks were equal, the 750FX is technically 25% more efficient in scalar integer. I should also re-emphasize that I never bothered compiling the test natively for x86, I left it java, so it's not out of the question the P4 could do this in 1 second - and that is *NOT* using any vector libraries, just plain old integer math.
I've found some documentation on the Altivec C programming interface, and this weekend I'm going to make a first attempt at vectorizing it. The integer test should be no problem, but my FPMathTest app that did square roots will be more difficult. With Altivec, there is not recognized double precision floating point, so this complicates doing square roots. If you want more accurate, precision square roots, you have to do Newton Raphson refinement. In other words more ************ you have to go through. I believe in SSE2 you have double precision floating point ops, and if you were to vectorize it, you wouldn't have to compensate for this.
Another theory as to why the P4 is scoring so good is because if I'm not mistaking (and I'm not), the P4's ALU runs at double its clock. So in my case, 5.6GHz. I'm sure this relates to the issue.
I don't know how true this is, but I wouldn't be suprised if there is some truth to it, surely some food for thought:
http://www.osopinion.com/perl/story/17368.html
The G4 was just a hacked-up G3 with AltiVec and an FPU (floating point unit) borrowed from the outdated 604
If this is the case, then no wonder why we are getting these abysmal scores, and no wonder why a 400mhz Celeron can nearly equal it, and no wonder why the 750FX can outperform it (different company, different fpu)

a nonsensical decision given that IE still has more than half the browser market and Macs can't run it.
security issues are staff issues...
I simply commented on the fact that you must ask Google why they abandoned MS Windows for commercial use and that Google knows better.
You come with an insulting post claiming they know more than me.
Good if they know more than me and I don't have an issue but mind your own business sir.
Sorry, I find you hard to comprehend, maybe because English is my first language?
anyway...

So, first it was the number of transistors per processor, then they coupled that with higher clock speeds (MHz) and now with multi-cores inside multi-processors.
Is there a limit to such growth with the current technology?
Anything after that? The optical computer that works with light instead of electricity and thus does not heat soo much? Any roadmap?
Thanks.

This thread is getting too funny. Apple has been so far behind on power these past few years and now we get the chance to use Conroe, and suddenly that's not good enough for the Mac snobs. Conroe is an extremely fast chip (especially compared to G5), so I don't get why some people think it's a bad choice for the pro-line up. Sure, it can't do smp, but not everyone needs or want to pay for quad processing.
So, aside from the ability to do multiple processing, what advantages does Woodcrest have that make it mandatory to go in the pro-line? How much "faster" is it going to be over the Conroe? It's my understanding that they are identical in that respect.Yes they are. I agree with you. But when I wrote that earlier in this thread, someone wrote that economies of scale dictated that Woody goes in everything Pro rather than only in the Quad. Makes no sense to me either. I think all non-quads should be Conroe.
