You know what I hate about crap like this?
People read it, and then point their respective (washed in soap with chemical additives and toxins) fingers at Appple, because it makes them feel good. "Yeah, this Apple stuff is crap!"
Then they go drive a block down the street to get milk from a cow who's waste runoff pollutes the local river, sit down and watch their TV with power generated from a coal-spewing power plant while eating dinner from plastic packaging that came from oil that was refined at a plant that contaminates the environment.
Unless you live on an uninhabited island, catch all your own food and generate your own power, you have no room to talk. None of us do.
Excellent summary.

If you head over to Apple's environmental page and read through it (which I have done several times) you'll see that much of what they claim to be doing for the environment is actually more along the line of what is called natural capitalism. That's not to say it's bad, but don't let them fool you into thinking they have the environments best interests at heart. They're looking out for the bottom line. They make claims about LCDs, but manufacturing energy and toxic inputs on LCDs vs CRTs is a pretty poor argument (read LCD vs CRT report by EPA to see exact figures). Apple can claim a lot of environmental victories, but many of them are simple side benefits of the movement in their product line. LCDs use less energy and have lower cooling costs in lab environments. Core Duos take less energy than G5s. These are true, but Apple didn't switch to save the world.
Dell has come under a lot of pressure recently for their poor environmental track record. From their lack of a takeback program to their recycling of components using prison labor. They're been forced to clean up their act. They have a pretty amazing takeback program. Apple has a really horrible one. I've used both. Apple needs to step up here. They have a program that seems to exist simply so they can say it's there. Apple has also pulled products from the European market instead of redesigning them to meet new toxics standards. Dell switched suppliers and kept their products world wide. Greenpeace should be targetting Apple here. I hope Apple reacts. Good quality products, with a long lifespan a low environmental impact benefit everyone.

They are , you will not see any performance differences between Merom, Conroe and Woodcrest at equal clock speeds, unless u go SMP. They will all encode , render , transcode at the same pace. The FSB means nothis as it has yet to be saturated even a 667mhz. Tons of test and benchmarks at Xtremesystems done over the past few months have proven this.
Making the MAcPro line all Dual will be a Big Mistake and will backfire on Apple and force many pople to go right back to PC. I can Promise you , if u want a Woody in a MacPro be prepared to pay an entry fee of $2499 to join this exclusive club of idiots.
I remeber when my iMac G4 was starting to show it'sa age and when the time came to replace it , the minimum price for a real desktop Mac was (and still is) $1999 for a dual 2.0ghz G5. So what did i do , I said goodbye Apple and built a better machine for 1/2 the money. Till this day I have no regrets and would never go back unless i was in the market for a notebook then i'd get a macbook.
I still can't believe Apple still has the balls to charge $2000 for an outdated Desktop that gets Outperformed by an $800 PC. While still having a smaller hard drive , less ram , less usb ports , no card reader. Jobs believes you mac loyalist are stupid.
Believe me Bro i've already been there.:D
Does not sound like you have been anywhere. Whether the entire line of PM's need to be SMP is a question for someone close to the sales data. I find your assuming everyone want to use a computer like you very arrogant and simple-minded. Why are you even on this website? If you hold Apple in such distain, why not go find a place where you can bond with other folk who have only achieved the same level of computer knowledge and manners as you.

It auto-executes the installer because installers are marked as safe if "open safe files after downloading" is turned on.
Fine, so I can write an installer that will just wipe your user account while you read my EULA and you'll happily execute it because "hey, it's just an installer" ? :rolleyes:
This is not an example of shellcode being injected into a running application to execute code in user space.
This is not, but I'm interested in the mechanics because next time, it could very well be. That's my point. Some of you guys aren't cut out for computer security...

According to the APA there is no sound science behind conversion therapy.
Some quotes from Nicolosi:
�If the father drops the kid and the kid gets brain damage, at least he�ll be straight. Small price to pay.�
�When we live our God-given integrity and our human dignity, there is no space for sex with a guy.�
�I do not believe that any man can ever be truly at peace in living out a homosexual orientation.�
I wouldn't have made the first comment, and I think he shouldn't have made it.
Here's a video of an interview with Dr. Robert Spitzer, the psychiatrist who helped the APa normalize homosexuality before he discovered that some homosexuals could change their sexual orientation (http://www.youtube.com/watch?v=ZwE6_dLweYo). I post the link to the video partly because I agree that James Dobson's organization, Focus on the Family, should have admitted that Spitzer thought very few homosexuals did that.
I agree with Nicolosi's second quoted comment, but I wonder I what kind of right he meant in video three, the one I asked you guys to watch part of before I wrote this post. During years of counseling, I've noticed that some therapists need to think more analytically than they do think. One counselor kept saying "selfish" when she meant "assertive" and told a group that suicide was one of the most selfish things anyone could do. At least I knew that she didn't mean that people were being assertive by killing themselves.
I don't know what to say about Nicolosi's third remark.

Look I'm not childish or demanding I just disagree with the way At&t has sucked many of us into the Unlimited plan from the beginning. After a time we all had it and they came out with the secrete 5GB idea. You want posts of me complaining back in 2008? Why ? I don't have to prove anything to anyone to state my opinion and dislike of the policy.
Don't point the finger at me and say I'm stealing, I paid for my internet use every month for over 3 years now.
I'll cut back on the righteous talk if the finger pointing stops.
I do not tether on a regular basis and have not for 6 months.
I do not Download with my phone except apps and docs.
I agree there can be abuse even with unlimited
(ie: the people who claim 90 and 120Gb a month DL)
You feel your right,
I feel I'm right,
we disagree, end of story :cool:
Also At&t will do this from time to time and unless something changes that stops them there is nothing we can do about it.

And of course atheists will be less trusted. Atheism rejects non-societal Morals (unless you want to pull the "absolute morals exist and god(s) do not" version of atheism). Morality is completely defined by society at that point or at a more direct sense, by us.
Are you as a theist not glad that morals are defined by society and not 4,000 year old books?
Go stone someone for cursing at their parents and come back to me on that.
Once again, atheists have a lower prison rate than Christians, and are likely to be more educated.
Atheists have no de facto reason to discriminate against any people group.
Atheists don't need to feel watched to do the right thing.

Don't get me wrong, it's good that companies are giving time scales, but they don't really mean jack until they're implemented (the UK committed to the Kyoto protocol and will miss it's commitments by miles)
That's not true. The UK will miss the targets that Tony Blair committed [us] to. Blair's standards were almost double the standard Kyoto targets. We'll miss the Blair targets (surprise surprise) but we should hit the Kyoto targets. See here (http://news.bbc.co.uk/1/hi/sci/tech/4849672.stm).
Of course, much of Kyoto is rendered moot because the US refuses to ratify the treaty because "it will harm the economy." :rolleyes:

Hmm? I'm not really sure what this means. Can you explain?
Wow. I could see this being a pain in the butt when we're used to just clicking on 'Close Window' and we're done.
Are you guys sure that switching is really "worth it"? (serious question)
One can delete icons by dragging and dropping them onto the desktop from another app or the dock. However, they are not permanently deleted from your hard drive. It sounds strange at first, but it is pretty cool once you get use to seeing the icon mystified, saying it is thrash. :eek: Both Windows and Mac thrash icons are waste paper baskets. :)
There are videos on Apple's web-site titled something like "switching from Windows to Mac 101 or the switch basics." I do not remember the exact title, but mine are close. These tutorials will be helpful! Check them out! Also, you can drag items such as photos and video directly onto the desktop with the mouse.
As far as regretting the "switch," no way! :) OS X is easy to use and the 'finder' is pretty much idiot proof! While using Windows, I struggle to find simply things like documents and system files, because you have to add exc and other computer jargon to find what you are looking for. Point being: using the finder incorporated into Mac OS X to hunt down documents and system files is easy. Plus you can search specific aspects of the hard drive. Like the entire hard drive, your music library, applications, a.k.a. apps (which are programs in Windows land,) or your documents. Each are separate folders to conduct a search for 'X' file, app, or song.
I am not bashing Windows though! This must be noted, because I am not a wiz with any operating system. Each OS has its pros and cons and I am unfairly pointing out the cons of Windows, because that is your request. I like to use computers, as I am a button pusher, but I do not how they tic. :D

Having the tools doesn't mean you know how to use them - but with more people having the tools thinking they do - the value of those that REALLY do can be affected if it appears that "anyone" can do it.
That's a pretty common thread of thinking in the creative business. I mean, test tubes are pretty cheap but you don't get every tom dick and harry claiming to be biologists, right? :)
Professionals don't have to worry, unless there's a hoard of untapped creative genius lurked out there.
A poor editor will have a poor showreel. That'll never change. All that changes is the number of canned effects we have to look for to realise that they didn't do the clever stuff on their own... Damn those "do something clever" buttons!

Do you have evidence of this just out of interest? I too was surprised to read this, so I'd be interested if you had evidence the other way.I wonder if they mentioned the fact that Dell has made the computer a disposable purchase with their $299 PCs. I'm serious people buy a new Dell every few years because they are garbage. Do you honestly think people give them back for recycling. They sell them on ebay or craigslist, and the new owner after about a year puts them in the dumpster. With Apple people keep their machines much longer, and are much more likely to recycle them because they are smaller and easier to take to a recycling center (no CRT). This alone makes Apple greener then Dell.

There are arguments and counter-arguments to both camps, which is why I choose to be agnostos. In the face of a dearth of evidence it's more rational to withhold judgment than leap to an extreme position.
In science when there is a dearth of evidence for something, you fail to reject the null hypothesis (which is that hypothesis x is incorrect).
If I wanted to make a claim about something, say that two bricks tied together will fall at the same rate as a single brick, I first have to make this my working hypothesis. The null hypothesis is that what I'm asserting is not true (in this case the null is that the bricks will fall at different rates). It's up to me to provide the evidence. If there isn't enough (or any) evidence, we fail to reject the null hypothesis.
When it comes to religion, it is the theologian who is making the claim. Thus, his working hypothesis is, "God exists." In searching for evidence, however, we come up with nothing. Thus we must fail to reject the null hypothesis, which is, "God does not exist."
Agnosticism is really the position that the an affirmative statement on the matter of deities is impossible to know. It doesn't have a rational basis in logic or science, thought it might make some people more comfortable with their skepticism.
Atheism is the position that, based on currently available evidence, there is no basis to consider any deity to be real. This could change as new evidence comes to light, of course. That is a quality you will not find in theism or agnosticism.

As far as I'm concerned it is the same as going to an all you can eat restaurant and sharing your food between two people, while only paying for one. It isn't a serious crime, but it is stealing, and you know that if you get caught you will have to stop. I'm not going to feel bad for these people that are using 5+GB per month.
I don't think it's really like this in practice, because 99% of the time people are probably using one device or the other, they aren't surfing around and watching videos etc on the iPad and iPhone at the same time for example. They COULD do it, so I guess the analogy works, I just don't think there's a lot to worry about there.
I agree that if this is explicitly laid out in the contract we signed, we can't really get mad. I do think it's retarded though- with normal Internet service, you pay a single fee and connect any device you want... computers, phones, game consoles... buying service from a phone carrier should ve the same. Because in most cases it really DOES amount to paying for the same data twice. You'd have to have multiple people using each device simultaneously to really get your moneys worth : /

Now that we know the real truth about the "better standard FPU", I thought it was time to shed some light on non vectorized G4 integer processing.
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)

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:

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)
