JustAGuy: Okay, I modified that for 5000 and compiled on my Athlon-Tbird. Runs in about one second on average.
In fact, put back the 20000 values in both and compile it using:
gcc -mcpu=7450 -O2 -pipe -fsigned-char -maltivec -mabi=altivec -mpowerpc-gfxopt -funroll-loops -o benchmarker benchmarker.c
Or hell, use this C code:
#include <stdio.h>
int main()
{
double x1, x2, x3;
int result, startTime, finishTime;
startTime = time(NULL);
for (x1 = 1; x1 <= 20000; x1++)
{
for (x2 = 1; x2 <= 20000; x2++)
{
x3 = sqrt(x1*x2);
}
}
finishTime = time(NULL);
result = finishTime - startTime;
printf("This computer processed the double precision test in %d seconds.\n", result);
return 0;
}
And also, ddtlm, PLEASE tell us how you compiled your asm files and such so we can duplicate the results.

Fear of death. That's why religion was invented and why it will always exist.
actually it is not the fear of Death ... many religious people do not worry when their time is done ... for them "the afterlife" trumps everything

Firstly, let me say I'm against DRM if it restricts me using my own music I've paid for, but equally I see why artists don't want me uploading my iTunes Library to Gnutella.
Now, this "I do it to help Linux" excuse, it's rubbish. I've no objection to people choosing Linux (I use it on several servers) but to then moan it can't do xyz is crazy. If you need to watch DVDs, access iTunes, play The Sims, use Word etc then you should be running an OS that can do those things not by hacking support by illegal means. I understand the frustration of not being supported, but again it was by choice, lobby Apple to do Linux iTunes.
I applaud this software for giving me my usage rights back, but lets not make DVD Jon a hero of Linux, he just likes beating the system.

Isn't this misleading? It says 'shipped' not 'sold' so I assume basically it's a bogus report. You can ship all the crappy tablets you want..doesn't mean they sold.
I'm trying to find more on it but as far as i've read somewhere apple's data is always on units shipped including those that were used as warranty replacements (pretty much they count one as two in this case) for example. Waaay stretched in my opinion.

Very true. Plus it could be a fad to own the latest toy. We won't know until some time passes. Anything new from Apple gets a lot of attention.
Wait til the newness wears off.
I'd say time has already passed and has shown that the iPad is a useful and coveted device. It isn't a fad at all.

there were actually three redundant cooling systems, but they all failed.
in honesty i think it's unfair to claim that they were unprepared, or that there were maintenance safety protocol issues.
what they went through was unprecedented, and beyond the worst case scenarios they were designed for, so if the accident is fully contained (which unfortunately seems less likely as time goes by) the whole system should be commended.
of course, this all should be a pricey lesson to e learned from, but it could have been a lot worse. a lot.
Also, i was actually positively surprised by how direct and candid the japanese gov has been, after a bit of stonewalling at the beginning. not sure the same would have happened elsewhere.

I do not want to enter the "debate" about whether or not DRM and copyright laws are "good" or "bad." But for everyone who believes that the creation of this software was a good thing I would like to suggest that you put your efforts into more productive things, like starting a legal defense fund for that poor individual(s) who helped create the PyMusique software.
I'd just about be willing to bet that federal law enforcement agents will be knocking on his/her door within the next few weeks. No doubt, if Apple wants to press this issue those individuals could be charged with some violation of the DMCA or laws covering internet commerce . I suppose that they could even be charged in a civil suit for violation of the iTunes Terms Of Service agreement.
Seriously, if it is true that some of these people live in the U.S. and they've used their true identities then they could be headed for real trouble. Get their legal team ready (and, of course, I know you'll all be contributing money for their defense). :)

Dropped calls on AT&T are just a thing that you learn to tolerate. Even in our Houston area, where signals are strong on 2 iPhones, my wife and I drop calls each day in her 30 minute drive home. It seems to happen in the same areas so it may be when the calls get handed off to a different tower.

Photoshop & AE are awesome applications. Premiere might be a decent editing app, but nobody in the industry uses it. A very small % sure, but only because they don't know FCP or Avid. Maybe do-it-all small post houses, but not dedicated editors. I'm not really trying to knock Premiere - just stating facts.
The BBC just purchased 4,000 Premiere systems.

There is no way in heck that the performance delta can be so large without a large difference in quality of JVM. G4's may be slower, but they are not as slow as those number indicate.
Like I've been saying, when you start to see 5x leads by the PCs you need to start asking questions about the fairness of the benchmark. The G4 is better than 1/5 the speed. There are very few things were a P4 can get better performance per clock than a G4.
BTW:
Your G3 results as bizzarre as well, because of the contrast between them and the G4 results. Do not take it as proof one way or the other of the G3 or other IBM chips being superior to the G4. What we have here are raw numbers that defy a simple explanations. We should ask why these numbers are popping up, rather than running off with them as if they were uttered by a great voice in the sky or somthing.
I should note that the 90 second and 72 second results I just recently posted are from my cocoa implementation, not java.. so the jvm is out of the picture now on the mac.
Do not take it as proof one way or the other of the G3 or other IBM chips being superior to the G4.
Don't worry, I don't make assumptions like that. And no, I don�t think this does defy simple explanations. I will say that, what we are starting to see here is evidence that the scalar units (integer and fpu) in the IBM 750FX (G3) are more efficient than those in the Motorola G4.
If this is true, then my program hit it right on the nail. Also if this is true, it means there exist theoretical situations when using non altivec code that it would be faster on one of these newer G3 chips.
Also what alex said about how tedious it was to make altivec code, I would agree there is some truth to this. When you vectorize code (either for the P4 or G4), if you don't watch your p's and q's you can actually slow *down* your code. Just because you use the nice and special vector registers on these G4 and Pentium 4 processors does not mean you gain 5 times the speed. You literally have to take your methods back to the drawing board. You will only get peak performance out of pipelined, fully vectorized code.
None the less, scalar operations on both G3/G4 are miserable compared to x86. The JVM is no longer the deciding factor in the performance delta. It's out of the equation on the Mac since the benchmark is now a 100% native cocoa application with c code and no longer java. Mean while on the x86, the benchmark remains java.
70-ish seconds navtive on a G3
90-ish seconds on a native on a G4
5.9-6-ish seconds running under JVM 1.4.1 on a P4

Have fun sitting down to your computer to record shows. I get the vision, I reallly do, and I wanted Apple to pull it off better than anyone. But having to record HD content from one piece of hardware, convert it on my computer, load it onto iTunes and stream it to another piece of hardware (iTV) isn't exactly user friendly. The fact of the matter is, Apple doesn't really want you recording TV. So, while not impossible, you do have to jump through a few hoops. Having used TiVo for years, I would never convert to such a complicated system. If Apple had a DVR, they'd also have my business.
You are making a lot of Assumptions regarding complications. The addition of USB to iTV makes a host of third party addons possible that could easily surpass Tivo.
Wait and see -- it happened quickly with the iPod 4 years ago. It will be cheaper too -- no monthly fees and all managed by Front Row.
Now that is EASY!

The thing is, do Apple care about being outpaced sales-wise? They may just be content to make their products smoother and sexier than the better Android phones and be the Mercedes.
If they want to be in the sales race they need to get the 32MB iPhone free on �30 per month contract like other top-end smart phones, not �230 on a �35 per month contract. As Android and Maemo and tothers improve that massve Apple tax won't wash.
They also need an iPhone nano to compete with the HTC hero type phones.the iPhone is getting outpaced in sales by Blackberry and symbian. nothing will change that. if android eats away at symbian sales, they'll definitely be ahead of the iPhone. but what's more important to Apple? selling 8 million iPhones a quarter? or selling the cheapest phone to everyone?
i'm also wondering, do we think there will be a better android based phone than the nexus one? i'm not talking about adding more pixels or an incremental spec bump. where do they plan to go next? i don't know what apple plans for the 4th gen iPhone, but i doubt it'll just be the iPhone 3.0 + "features that Google has."

After hearing some parts of your mind, you definitely correlate well with your Android device.

This. I wouldn't mind paying a bit more for tethering, but the $20/mo extra or nothing is really unacceptable. For those of us who only tethering sporadically, it's really a waste of money paying $20/mo. If the carriers really want an extra revenue stream from tethering, they should have different options available.
I would easily pay $5-10 more a month for 1GB of tethering data, and for those who want 2+ gigs for tethering, then $20/mo is fine. They really need a lower option.
Damned if they do and damned if they don't, aye?
When ATT provides options (whether you like them or not) - you have a choice. You can either choose to take advantage of the options, not use them, buck the system and deal with the consequence, or terminate your agreement and move to another company.
When they didn't provide options- people were up in arms over not having any choices..
Everyone can be an armchair critic, lawyer, etc... I would imagine that few if ANYone here is qualified to determine what ATT (or other carriers) can or cannot/should or should not do when it comes to their business model. You speak (naturally so) for yourself and some of your fellow customers.

It's too expensive. as a business, why buy an imac when I could but a dell or hp for a fraction of the price to do the same job?

I'm inarticulate. Well, if it is extending benefits heterosexual marriages then examine why it is doing so and then see what the differences between a heterosexual marriage and a homosexual marriage would be.
The reason you are telling me to do that is because you cannot. Neither can the government. That's why it is wrong.
Nearly forty years ago psychologists declared homosexuality was not a mental illness. Nearly ten years ago the Supreme Court ruled that the government has no authority to criminalize consensual sexual acts between any two people, regardless of gender, in the privacy of their own homes. The state of the art in science and law once provided justification for the discrimination you want. Neither does any longer. It is no longer understood to be the case that homosexuality entails a necessary harm to the participants or anyone else. Quite the contrary, same-sex couples are known to form loving, supportive, monogamous relationships every bit as profound as those enjoyed between men and women.
This being so, the government has an obligation to prove that this distinction has not outlived its legal relevance. Hint: it has.

The whole "it's MY data, I can do what I want with it!" argument is countered by your perfect analogy with a buffet. I tip my hat to you on that one. If you're at an all-you-can-eat buffet, it doesn't mean you can share your food with your entire family.
I've always believed that unlimited data, on a smartphone, enables you to connect to the internet as much as you want on the device you're contracted to. It's not like home internet where you can share the connection, nor have I ever imagined it would be.
I think that people just like to get "angry at the man" when they don't get things the way they want. ATT is trying to improve their network, good for them.
If AT&T let you keep your "unlimited" data plan AND add tethering, his analogy would work. As it stands right now, AT&T forces you to downgrade to a capped data plan and add tethering to it which essentially doubles your data cap to 2gb.
The analogy is more accurately like a traditional restaurant where you order an entre that is not "all you can eat". But in this case, they don't allow you to share it with another person, even though you could never possibly eat all of it by yourself (use your existing data allotment). However, they are more than happy to let you buy another entre. Oh, and you can't take home your leftovers either (rollover). That does a little better job of highlighting exactly how AT&T is being greedy in this scenario.
Bottom line, what people are doing is sticking with unlimited data and tethering (using some other means), and then downloading gigabits of data which does affect network performance for other users. That is how AT&T sees it. If you are careful about what you do while "illegally" tethering, and how often you do it, I seriously doubt they will figure it out. They really aren't that put together on this, as anyone who has spoken to "customer service" can attest.
