Nintendo and Sony beg to differ....
Here is an easy way to explain it. You can heat a slice of bread in a toaster and a microwave oven. Are you going to say microwaves compeat with toasters now. When they do not heat bread the same way.

You should try those tests with some of the compiler flags that I used in my post a few posts up, which I have been editing.
Right now I am looking at the assembly that gcc is generating. It looks like gcc gets the answer in a very strange way.
javajedi:
One more question i have for you while you are responding: What you suggested may very well be accurate, the compiler is making some really poor decisions, however if this were the case, what about javac?
I don't have an answer to that at this time, but it seems to me that we are looking at different quality of JVM's. I could see a P4 beat a G4 by a fair amount, but lets be realistic... the G4 is not so slow as the numbers here have been suggesting.
I wish I knew some PPC assembly. :) I would code up some stuff for that too, and I bet the nubmer of registers would help a lot. Registers are great for loop unrolling.
Anyway, some time ago you asked how the G4 has better scalar units than the G3. Basically the FP units are similar but the G4 unit has a lower instruction latency when doing double precision (in the G3 doubles take one more cycle than singles, on the G4 they are the same). Also, the G4 has 4 integer units where the G3 has only two. This is not always useful, but in this problem if I could do PPC assembly I could easily overwelm all 4 of them.

I just switched. Like, a week ago.
1. Expose + Spaces are GREAT window managers. I took to both like ducks to water.
2. Spotlight is pretty awesome and intuitive. However, Win 7 has features like that integrated.
3. I never used the Explorer, always just navigated through folders one by one (bad habit, I guess). So Finder has been a bit of a learning curve especially since the opening folders behavior is not quite the same. Like when you double click on a new folder a new window opens up.
4. No registry is great. Installing/uninstalling apps is clean and efficient. Just the way it should be.
5. The Dock is a mess. Of course, this is nothing new. Many, many people have spent tons of time talking about it. However, it is fairly intuitive and simple to use. It's also very tweakable for those who want to do it. I guess that's why Apple has kept it around.
6. I like how Mac OS X keeps all the power user features out there and accessible. Automator for example. OS X looks nice and is easy to use but is actually extremely flexible and powerful. Windows, of course, you can do a lot to tweak it, but it just doesn't feel the same.
7. Quicktime-stuff and iTunes run MUCH better on the Mac. No surprise there.

As marriage is licensed by the state, it is in fact a privilege. The fact that it is near-universally granted doesn't make it any more a right.The fact that something is licensed does not change it from a right to a privilege.
Article 16 of the Universal Declaration of Human Rights declares that "Men and women of full age, without any limitation due to race, nationality or religion, have the right to marry and to found a family. They are entitled to equal rights as to marriage, during marriage and at its dissolution. Marriage shall be entered into only with the free and full consent of the intending spouses."
For most of Western history, marriage was a private contract between two families. Until the 16th-century, Christian churches accepted the validity of a marriage on the basis of a couple’s declarations. If two people claimed that they had exchanged marital vows—even without witnesses—the Catholic Church accepted that they were validly married.
State courts in the United States* have routinely held that public cohabitation was sufficient evidence of a valid marriage.

As much as I want to say that it s a grass is always greener type situation, in Phoenix AT&T is considered the worst. Especially indoors. They really must stretch the towers out here in the desert. I can;t even use my iphone in my home.
I live just north of Seattle. I have an AT&T cell tower (sign on tower base identifies it as such) within line of sight less than a quarter mile away in a residential area. Inside my house I have never had a single call successfully completed on my iPhone. They have all dropped out. If I step outside where I can see the tower, about half the calls drop out. I also have delayed reception of SMS and voice mail. For example, this morning I received a voicemail that was left for me the previous evening. I've replaced my phone and cards twice without luck. My neighbor has Verizon. He can stand inside my house right next to me, get full bars, chat up a storm, SMS, browse Internet.
Go figure.

Apple may need to take steps to avoid confusing consumers. Their multiple consumer products make it complicated for people who don't know Apple's product line, aren't particuarly technical, aren't sure which are products Mac-only and which are cross platform, and don't know how their hardware, software, and O.S. fit together.
There are plenty of people out there who don't realize iPods are made by Apple, and iTV (whatever it's true name turns out to be) will confuse them further.

Why is it that hard to understand? Because every OS has files that users should not and could not touch. OS/X is not an exception to this rule. Showing these files to users in file manager generally makes user life more difficult. What's the point of seeing them if you can not do anything about them? Also, it reduces the chance of doing something stupid with these files accidentally (like removing).
Windows has an option to hide such files. OS/X does not.
So OSX allows user access to all critical files with no option to hide?

So now were placing importance based on what? Suicide is suicide.
We're placing more importance on the bullying of gays because of the historical and widespread discrimination, hatred, and violence that gays have had to endure (and still endure) that obese people have not. We discussed this 8 pages ago.

Apple is more green than dell. period.
Makes me question the whole report if greenpeace thinks dell is more green then apple.
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.
Edit:
Did I read that correctly?
Sorry, I may not have been clear. I meant it as in I would much prefer to use OSX over Windows or Linux, and so would find it difficult to choose, say, a Dell because it ran Windows and I would find that unpleasant, even if Dell had a better environmental record.

the iTV doesn't do HD either. Quoting Bob iger, Disney CEO:
http://www.appleinsider.com/article.php?id=2066
IMHO Iger's comments are referring to the content at the store, not the capabilities of the iTV. The iTV is so clearly designed to complement an HDTV with its outputs, if they crippled it to have only 480p output they would have failed. Plus, Steve already demonstrated playing an HD Trailer.
We shall see...

We don't need nuclear, or coal or oil for that matter.
A large (think 100milesx100miles) solar array in death valley for example, could power the entire Continental US.
No it couldn't. That would require grid energy storage technology that currently hasn't been invented yet.
Look up base load generation. There are only a few sources of generation that fall under this category. Nuclear and coal are among them. Most renewables are not.

Damn multimedia, you are making me want that Dell! I just went to the Apple store to check out the 30" (pulled a stool up to the machine from the genius bar and tried to see if I could handle all that real estate). I am usually a sucker for Apple stuff and having matching componentry...but that dell is so CHEAP!

As a Norwegian I can say that Apple has way more credibility than Greenpeace over here. We have seen what they are all about. Greenpeace is a bunch of spoiled city kids that has no idea what nature is.
Yeah, cause you just HAVE to hunt whales and eat whalemeat in Norway in order to survive, such a poor country with poor people. How dare Greenpeace oppose your ancient way of life?

I don't know if Intel ever changed it, but one of the historical reasons you couldn't make a scalable multi-cpu x86 system is that x86s did bus snooping. Once you got more than ~3-4 x86s on the same bus the bus would be saturated by snooping traffic and there would be little room for real data. I think that's why Intel is pushing multi-core so much, it's a hack to work around Intel's broken bus. The RISC cpus (MIPS et al) didn't do that, that's why all the high cpu count systems used them.
Interesting, I wasn't aware of that. Thanks for the info. :cool:

I could really care less about breaking some DRM law or "international copyright law". I would love to see them try to enforce it.
Just because a man can do a thing does not mean that he should do that thing. Whether or not you will get caught breaking the law is irrelevant to whether what you are doing is or is not legal. I can go to the supermarket or gas station and steal a bag of ice from outside without getting caught, but it doesn't mean what I'm doing is okay. You might say it's not a big deal--it only costs a dollar, and anyway the supermarket makes tons of money off the other things that they sell, and they probably don't deserve all that money because they underpay their employees.
Moral relativism and justification might make you feel fine about doing it, but it's still wrong and it's still illegal. If you don't care, that's your thing.

Actually, I do think this would bug me. I love that I have all of my most used programs (Word, Excel, Photoshop, Lightroom, Notepad, etc, plus one particular folder) right there for easy access with 1 click of the Start button -- yet hidden away completely out of sight (until I click on Start). I also love having quick access to my "Recent Items" list, to quickly open a file I was recently working on.
How are the above 2 things done on a Mac?
eek... I use "alt-tab" and "copy & paste" A LOT! :eek:
Doesn't Mac have these things too? :confused:
Recent items are "today, yesterday, and past week." I checked with the 'finder' and a document showed up yesterday without accessing my documents folder. Hope this helps, as you sound computer savvy!

How does that matter? Last I heard, iPods didn't cost $.99. Plus Apple doesn't get $.99 per song, they get roughly $.34. iTMS makes Apple money, sure... but compared to the amount of money iPods make them there is no comparison.
I've said it over and over again, and so has plenty of others... iTMS exists to sell iPods.
I've used iTMS before I bought my iPod Shuffle (way cool!) to simply download music and burn to it CDs. Beats the inconvenience of running out to Walmart and buying the CD for even more money. And I get to search and preview. This is the best way to buy music WITH OR WITHOUT a portable music player.
Also, $0.34 is a nice profit per song * 300+ million songs and growing. Not bad business for just pushing bits! :cool:
Off Topic: Any with an iPod Shuffle think the plastic is reminiscent of Lego (R) plastic?

ddtlm check this out, this may suprise you:
I ran the double precision test (sqtrt()) for the first time today as a c program. I compiled on the same machine as I ran the java version, with gcc version 2.95.3-5 (cygwin didn't come with 3.x).
Here are the parameters to gcc:
$ gcc -march=i686 -O3 -pipe -mpreferred-stack-boundary=2 -fforce-mem -fforce-addr -fexpensive-optimizations -funroll-loops -fomit-frame-pointer
Using this, the C program does it in 7.01 seconds. The same code, in java does it in 5.9. The javac, or the jvm seems to better be able to tear apart the loop. I think Java being "slow" is another common misconception that people have ;)
Oh well...
Meanwhile on the PPC side of things, I compiled the fp test against:
mcpu=7450 -O2 -pipe -fsigned-char -maltivec -mabi=altivec -mpowerpc-gfxopt -funroll-loops
Ofcourse this is running in 10.2, and I'm still stuck at around 90 seconds.
Is there anything else you think we can do aside from vectorizing it? Lastly, now that we're all on the same page now on how we are compiling this, I reran the silly single percision int test, and my powerbook looses out to the 750FX. Same platform, same code and everything, but heck?

When did you all gain the right to be so selfish, self-centred, and bigoted in your beliefs?
Funny, I thought all people had "the right" to believe anything they liked. When did you gain the right to be so imperious and condescending towards others just because their opinion doesn't agree with their own?
Anyway, I'm sure Apple and a whole load of other companies could do better in regards to environmental issues, but it always seemed to me that Apple was doing a pretty good job. I remember the iPod recycling program in their stores where you could bring in your old iPod and get 10% off a new one. I have also noticed that lately Apple has greatly reduced the amount of packaging on their products. Of course they still need to use styrofoam to keep the computers for getting damaged when they are shipped, but in some cases their packaging is almost half the size it used to be.
So although I'm sure they could do better, I think credit should be given where it is due.

Now why do hackers have to go do this? they say they do it cuz the prices that cd's are is "unfair" and "overpriced". now i simply have to ask the question... if your a hacker.. more than likely you deal with computers. dont you think that your overpaid for you job? for a small simple example.. best buy geek squad.. overpriced.. they want 30+ dollars to install a stick of ram. the point is... the money is for the most part equally distributed to be able to pay these high prices. income is accomidated for the high prices of products. if u think it's bad over here.. go to japan and try and buy a medium fries on their "dollar menu" which in usd=$5. so back my main point... just pay the frick'n money, most ppl's income are accomidated for the increase cost. if you feel u cant afford a cd... that's what christmas or your birthday is for or even the radio. by the way... i'm not an "artist" either... im majoring in ECE myself so i'm not biased.

Even if the internal architecture of the two chips is the same, a Dual 3.0ghz Woodcrest configuration is still going to outperform a Single 2.66ghz Conroe. While Conroe might be very good, it's not the best, which is what pro customer's expect from Apple's highest-end workstation offering.
I thought it was pretty obvious that I was talking about a potential single CPU Mac Pro. Woodcrest would obviously have to be used in a dual CPU machine. Also, I'd expect that lower speed grades would be offered too, which would make a 2.66GHz Conroe a nice pick. Or is only the absolutely highest clocked version of the CPU good enough to satisfy the demanding professional Mac users? :rolleyes:
Sorry, just tired of the so called professionals that can't stop whining about how anything other than the best is an insult... It's annoying and it gets old fast.
