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?

What really sucks is how the leaders of the Catholic Church covered up this abuse and allowed it to continue. Surely they will burn in hell over that.
Nope; they wont. But that's only because there's no hell.
It would be much better for all concerned if they just went to prison here on Earth. Unfortunately, the pope made that difficult when he decided to cover up all the child rape.

I still maintain that there's a "hole" in the new line-up, which is there isn't a single-cpu high-clock-rate system. I think Apple needs a Core 2 Extreme based system with the Conroe XE CPU (initially 2.93 GHz then 3.2 GHz).
Since your concern is the high price of the Xeon, I find it ironic that you want to use XE in a Mac, since XE is also VERY expensive. I believe they cost about $1000 a piece.
I believe that the Woodcrests start at around $400, which isn't outrageous price. For the price of once XE you could have two 2Ghz Woodcrests.

The deal with religious people is founded in human nature; it's the need to have faith in something bigger than oneself. For some reason, the Church of Scientology comes to my mind when I'm writing this. Oh yes, here is my question: how many religions are founded on somebody's desire to exploit that need?
Lately I read that the iPhone was considered the world's greatest invention. It isn't. God is the greatest invention ever.

If it weren't a generous attitude I would call it naive. People following the Jewish or the Christian faith to a tee can be just as threatening to everyone's freedom and all-around democracy p just look at your own doorstep. It takes a secular Jew, Christian or even Islamist (of which there are more than you would think) to fit that bill.
I've explained somewhere else why there can never be an Islamic reformation unless they go against the teachings of the qur'an, which would be blasphemy because it's the literal word of god etc etc etc.
Truly secular islamists/moderates are extremists in the eyes of the major Islamic schools...
Christianity has been neutered thanks to the reformation and the enlightenment. We don't have anything more to fear from it ever gaining ascendancy again but please do correct me if I'm wrong.
And you then go on to explain how this doesn't exist in a church which is neither fundamentalist nor Protestant. I'm still at odds as to what point you are trying to make?
Wouldn't you consider the Orthodox Church to be fundamentalist? I thought fundamental meant basic... The Orthodox Church predates the Catholic Church...

The iPod was not a fad by any sense of the word. Once you reach a decade of popularity, it's not a fad. It's like calling land line phones a fad because there was a time when they didn't exist, then they did exist and were popular, and now they are fading due to cell phones. Ridiculous.
A fad is something that comes and goes quickly with a spike in popularity at its peak, and then people look back and wonder why they did it. That isn't the case with the iPod which still sells in the millions.
Amazing to see how people will resort to anything to make Apple look less popular than they are.

I accept same-sex-attracted people as they are. But I won't accept some things that many of them do.
What's pretty funny is that I'm sure Leonardo da Vinci did plenty of work for the pope and he was gay, and Michelangelo painted the roof of the Sistine Chapel, and he was almost certainly gay as well given what his art involves.
And clearly the popes at the time didn't give a damn about their homosexuality - I fail to see how in the intervening 500 years its suddenly become an issue.

Another fallout from terrible AT&T service is that in many shops and restaurants, at least in the San Francisco area, and especially Berkeley, you can't check in using location services like Foursquare or Facebook Places since there isn't adequate coverage- eg: no service, no signal etc.
That's bad for business.
Merchants too should press AT&T and local authorities for more towers and better connections.

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.
Or I have a better Idea: Call / Write Apple and complain about what you get for your hard earned $$$.......if enough people do, they will listen.
I for one am not ready to move on to PC....as I would have to learn Linux and find Linux versions of all my software....Windows XP never!

Ugh, just as soon as I had posted...
Beg to differ. You've been praising Japanese nuclear power plant construction as being superior to the impoverished Soviet ones that go into meltdown. Well, we've all now seen your argument for the 'testament to building codes' by 'experts on Japanese nuclear regulations' totally explode and is now lying in rubble. Unless of course you now insist that the building exploding and cllapsing on the core is part of the building codes? ;):
I haven't "been praising" their construction, I "praised" their construction in one post, if you can even call it that. The Japanese know what they are doing by and large in many of the things they do; that's why Japan has had 30% of its power delivered via well-developed, and well-understood nuclear sources for years, while the west is still outright paranoid of so much as a mention of the word nuclear.
The only thing I did was compare it to Chernobyl, or rather defend against it, as it certainly is not Chernobyl, and was built to higher standards than anything in the USSR during that time, that meaning Chernobyl.
You think they built the plant 40 years ago and have done literally nothing in terms of maintenance and/or upgrades since that time? You don't think regulatory statutes and codes have changed during the time, and they've had to comply with those and be subject to normal regulatory inspections that meet todays 2011 safety and energy protocols?
Just because the plant was built 40 years ago, doesn't mean it is the same plant as what was built 40 years ago. Trust me, I was and am full aware that the plant is older than Chernobyl. But the difference is that Chernobyl ate it during a time of 1980's USSR safety standards, when the international nuclear community wasn't nearly as effective as it is today. Today's plant may be 10 years older than Chernobyl, but it's 30 years further up to date. Nuclear plants in the first world don't exactly get the "build it and forget it" treatment.
I don't want to argue about this, because it's pointless since we are all hoping for the best and fearing the worst. But I do know a thing or two, and it gets tiring correcting false information proliferating throughout thanks to a bunch of people in the media who have no technical training and haven't a clue about anything. The Japan forums are ablaze with misinformation.
Nuclear power is generally pretty safe, and it's a shame the west hasn't been able to embrace it, IMO. That isn't to say tragic accidents can't happen, as they can, but by and large they are extremely, extremely rare.

Maybe not in the New Testament, but certainly in the Old.
Nope, not in the Old Testament either. There is a recounting of events which say what happened, but there is no commandment from God to "urge the believers to battle. If there are among you 20 [who are] steadfast, they will overcome 200...... And if there are among you 100 [who are] steadfast, they will overcome 1000 of those who have disbelieved...(qur'an 8:65) to this day.
The New Testament Abrogates the Old Testament anyway, so it's not relevant to Christians.

Will it support third party codecs?
Does it have an internal flash drive?
Will I be able to order Music, TV shows and Movies using it?
Do I need a separate computer to use it?
So far, I'm not impressed. How's it different than a media extender?
I would rather have seen a mac mini with core 2 duo, better graphics support, an internal 3.5" hard drive, and HDMI.
Outside codecs are doubtful. It'd support it in that if you convert the media that's encoded with the 3rd party codecs to something quicktime can handle.
Flash drive? *why* would that have any benefit. Too small. Very doubtful.
Ordering from it. Maybe. But then if you have 2 machines that it's pulling content from, which machine actually does the payment, downloading and storing of the file(s)?
A seperate computer? Seemingly, any OSX or Windows machine running iTunes will be what the 'iTV' pulls it's content from. So yes.
What's a 'media extender'?
I would love to know if those who are saying they'd rather have a Mac Mini, rather then an iTV (which would approx cost half what the Mini would) have ever used a Tivo or a ReplayTV. It's the interface that makes both of those what they are, the ease of use. It's what MythTV's always battled. Yes, you may be able to buy a Mini and morph it into an iTV, but at half the price, and having to spend the time dealing with it to make it all work, why bother? About the only justification for buying the Mini instead that I can see is if you don't already have a machine that can run iTunes.

But just like Windows, it's practically impossible to have any problems unless you do something stupid.
Another analogy - if you buy a car and put the wrong type of oil in it or inflate the tyres to the wrong pressure, bad things will probably happen.
If you don't know what you're doing with your own devices then maybe you need Apple to hold your hand.
You obviously don't work in IT or no anything about how viruses are spread. Windows can get a virus just by being on a network with an infected machine or opening an email in Outlook from someone on an infected machine. I fix these kind of issues for a living and see it all the time. The truth is its insanely easy for viruses to get onto, and hide in Windows. Windows allows the files to completely hide themselves even if hidden and system files are set to show. The only way to see them on an infected machine is to yank the hard drive and plug it into a mac or linux based machine then you can spot hidden infected files if you know where they are located.
So please, don't start with the "as long as users are smart" myth. It can easily happen to anyone, its a flaw in the OS.

Sadly the lack of a system bus faster than 133/167 and use of leading edge RAM technology is a major downside to Mac hardware. G4 with software optomized for it is still on par with P4, but when Altivec is not in the picture or MultiProcessor awareness, the Mac slips very fart behind. I still have faith that the G5 will make up for this gap.
As for OS X vs Windows 2000, I am not as technically aware as the above poster, however my own experience in a large office environment with heavy networking is that Windows 2000 has failed us. We are switching to Unix and Sun, because we can't afford the down time that windows 2000 is giving us, the cost advantage of windows not withstanding.
I have not come accross many large computer operations people that will tell me that Windows is a replacement for Unix. Not unless dealing with small size and limited budget.

I meant quad-core package (socket) - be it Clovertown/Woodcrest or Kentsfield/Conroe.
On a multi-threaded workflow, twice as many somewhat slower threads are better than half as many somewhat faster threads.
Of course, many desktop applications can't use four cores (or 8), and many feel "snappier" with fewer, faster cores.
_______________
In one demo at IDF, Intel showed a dual Woodie against the top Opteron.
The Woody was about 60% faster, using 80% of the power.
On stage, they swapped the Woodies with low-voltage Clovertowns which matched the power envelope of the Woodies that they removed. I think they said that the Clovertowns were 800 MHz slower than the Woodies.
With the Clovertowns, the system was 20% faster than the Woodies (even at 800 MHz slower per core), at almost exactly the same wattage (1 or 2 watts more). This made it 95% faster than the Opterons, still at 80% of the power draw.
You can see the demo at http://www.intel.com/idf/us/fall2006/webcast.htm - look for Gelsinger's keynote the second day.I thought so. This is the first time I have seen the term "Multi-Threaded Workflow" and I thank you for that. In the Gelsinger Keynote he calls it "Multi-Threaded Workloads".
I'm glad to see you confirm my suspicion that the 2.33GHz Dual Clovertown Mac Pro will in fact be faster than the 2.66 or 3GHz Dual Woodie when someone knows how they work simultaneously with a set of applications that can use all those cores a lot of the time. Very exciting.
Also thanks for the link to all those sessions from the IDF. Fantastic to be able to "attend" all of them. I'm stoked and looking forward to watching them ALL. I love all the new Intel self-promotional videos. Intel is happening and hip!
And no premium for that "ninth" processor when you buy a 2.66GHz Dual Clovertown after all bringing the total cost to $3,699 plus ram. So now I hope there will be TWO new lines in the Processor section of the Customize Your Mac page of the online Store:
Two 2.33GHz Quad-Core Intel Xeon [Add $800]
Two 2.66GHz Quad-Core Intel Xeon [Add $1200]
I now think I will opt for the 2.66GHz 8-core for $3,699 if Apple will offer it for sale.
The first 8 being a little over $400 each. With the 2.66 you get 2.64GHz more total power so it's like getting a ninth processor for +$400 IOW for no premium. Maybe Apple will only offer the 2.66GHz Clovertown so as not to confuse the buyers.
Wonder if the 2.66GHz Clovertown introduces heat issues under the hood.

Also thanks for the link to all those sessions from the IDF. Fantastic to be able to "attend" all of them. I'm stoked and looking forward to watching them ALL. I love all the new Intel self-promotional videos. Intel is happening and hip!
And no premium for that "ninth" processor when you buy a 2.66GHz Dual Clovertown after all bringing the total cost to $3,699 plus ram. So now I hope there will be TWO new lines in the Processor section of the Customize Your Mac page of the online Store:
Two 2.33GHz Quad-Core Intel Xeon [Add $800]
Two 2.66GHz Quad-Core Intel Xeon [Add $1200]
I now think I will opt for the 2.66GHz 8-core for $3,699 if Apple will offer it for sale.
The first 8 being a little over $400 each. With the 2.66 you get 2.64GHz more total power so it's like getting a ninth processor for +$400 IOW for no premium. Maybe Apple will only offer the 2.66GHz Clovertown so as not to confuse the buyers.
Wonder if the 2.66GHz Clovertown introduces heat issues under the hood.

I don't want to watch movies on my computer, so this sounds like a great product. I assume I can hook a USB drive with movies or music and download iTunes products directly to that same drive without a need for a computer. If I hook iTV to ethernet, maybe that drive can even become a file server of some sort. I can justify the cost of iTV if I can use it as a music streaming device, print server and file server. Let's see how many of these features will actually be there. :)
However, the price point for movies is wrong for me. I started using Netflix instead of going to Blockbuster, because of price and wider selection. Apple's offer is more than double the price for a movie, even without the cost of iTV unless I watch them twice or more. Apple's library is bound to be smaller for a long time to come as well. I guess instant gratification is the only saving grace. Well, considering I've never bought a TV show or music video, maybe I am not in the target audience anyways.

It's not good, I'll never be convinced otherwise. Look at countries like Denmark and the rest of Scandinavia how well they manage their power, the research, alternative (green) energy sources in play and working NOW ... it's incredible and goes unnoticed.
Yet they are still dependent on coal, oil and nuclear. Green energy isn't efficient enough. Also, if you didn't know, Denmark has one of the highest household electricity prices in the world.
NO nuclear.
Currently, that is same as saying no to electricity.
