Multimedia, I was wondering if you could address the FSB issue being discussed by a few people here, namely how more and more cores using the same FSB per chip can push only so much data through that 1333 MHZ pipe, thereby making the FSB act as a bottleneck. Any thoughts?
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.

Sheesh, I have no idea how Java is defeating C... and those scores are still bizzarre. However PCUser did get 8.86 seconds on an Athlon 1533 with the right compiler flags. Looking at that, I wonder if the compiler flags are the cause here. Since this whole thing is essentially sqrt(), I wonder if the newer x86 chips are packing some strange special sqrt() assembly instruction that makes this huge difference. Hmmm. Otherwise I wonder how an Athlon at a little more than twice my clock speed (compared to the Xeon) can post results that are more than 4 times as fast.
Anyway this is it for me, since this is the weekend. I'll look for some x86 fast sqrt function Monday at work (I am pretty sure that such a thing exists, and if so it may be used in this test).

My quad was to ship today, after waiting four business days and two weekend days for a CTO build (2 GB RAM). But I would feel sick to have had the machine for a week when the Octo's are announced. I hope this baby makes Logic Pro sing...Nothing will be better for complex music work than an 8-core Mac Pro. I admire your courage to realize the 4-core Mac Pro was more of a stop gap model than what the market needs longer term.

Well, not that I hope he's right, but words like these from people of high up places don't give any comfort.
Europe's energy commissioner Guenther Oettinger dubs Japan's nuclear disaster an "apocalypse,"
http://news.yahoo.com/s/afp/20110315/wl_afp/japanquakelivereport
yes, but it's a figure of speech.
however bad a realistic worst case scenario would be, it will not require permanent evacuation of anything but a few tens of square miles, if that.
for example, this is not going to be as bad as chernobyl by any stretch of imagination, since the design and built of the plant is much safer, and this uses water for cooling instead of graphite which is itself flammable. And in chernobyl, only the immediate surroundings and another area where the fallout was massive are still off-limits.
In addition, this plant is on the seashore, so about half of the contamination will be dispersed into the ocean.
on a separate note, i can confirm takao's post that many japanese cities have built "tsunami walls" including one of the cities shown in one of the videos (where you can clearly see the water coing over a wall and waterfalling into the city. It might have been inefective in a tsunami this massive, but I am sure they can work on smaller ones. One of the California nuclear power plant on the coast also has a similar 25 feet wall.
I also agree with takao on the bizarre design of putting the spent rods in a pool on top of the reactor and without any containment other than the cooling water and the roof.
it seems clearly a design flaw which hopefully will be/has been taken care of in other designs and fixes

I think what that statement is getting at is that they will definitely not be released any sooner than mid-November. (I'm assuming that's when they will be officially "released".) But how soon afterwards, you're right, is anyone's guess. Just look at what Apple has done with the C2D chips. It took them a little longer than some of its competitors to include them in the MBPs, and we still don't have them in the MacBooks. (Of course, we may never see them in the MacBooks, until Santa Rosa, who knows... :o)
I think I remember a very long wait time for shipments when the Mac Pro was first announced. Is it likely we'll see another extensive wait time once they accept orders, even IF they announce Octo-cores in mid November? Also, on a completely different note, will this processor upgrade effect programs that worked on woodcrest processors? As in, is there a chance a program that works on woodcrest wont work on clovertown?

Not really. Chernobyl has an estimated death toll of 4000. Let's multiply that by 10 for arguments sake. More people are killed each year in the US alone by car accidents. Nuclear power is still a fairly minor risk.
Huh? I agreed with you that there are more car accident deaths. But just as I said Chernobyl is an estimated death toll. My point is many deaths from a nuclear accident aren't known. I personally know someone who died from the effects of Chernobyl who wasn't included in the estimation. I'm sure there are many, many more.

Nope didn't escape me, I just don't agree with you or think it's worth discuss products that don't exist yet and comparing them to ones that do. That's not a "it's not fair" issue, that's a "stop suggesting a product you can't buy is better than one you can". You've not used one for any period of time that is meaningful, stop listing it as a better gaming experience.

Does anyone know how to use the app? The readme file is empty :confused:
to use make sure you have installed the GTK 2.3 from the site that you got the program.
Restart windows... :) I love that part :)
Open the program under the accounts window select login
put your login and password from itms wait until the status bar at the bottom says balance -0. Then just type the artist song etc intot he search
Select the song. to preview it select preview under the song menu or to purchase select purchase under the same menu. Once you select purchase you will get a confirmation window that has a cancel and purchase button once you click the purchase button it will down load to a folder located in C:/Documents and Settings/User/Music this can be changed in the preferences located in the edit menu.
Once downloaded just add the song to you itunes music library and away you go.
enjoy

I realize it's a little early to be gloating, but c'mon, it's definitely going to be conroe. Which, btw, I find even more exciting than the mac pro news because while I'll never have a mac pro, an imac is always possible. :cool: (though I'm thrilled about woodcrest in the mac pro anyway because it allows the imac to get conroe, and because it's great news for those of you who want a mac pro. :))

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:
Is anybody actually bothering to do this in the wild against any OS?
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...
The types of attacks you are referring to are not occurring in the wild on a massive scale. When was the last time you heard about one in the media?
At the moment, there is no way to prevent the kinds of attacks you are referring to on any OS if a vulnerability exists that allows the attacker to exploit a running application.
Webkit2 will reduce access to user space when Safari (or any app using webkit2) is exploited by restricting the privileges of apps on a per app basis.
Turn off "Open safe files after downloading" if you are worried about that type of attack implemented via "safe" files.

Someone inquired about the benchmark Java console program I created:
It's located at http://members.ij.net/javajedi
I've also included the source (FPMathTest.java) for the curious.
Download the class file and invoke it from Terminal via "java FPMathTest"
I must warn you in advance my PowerBook G4 performs miserabily. It does not utilize Altivec(G4), SSE2(P4), or other vector processing extensions.
Enjoy :)

Reading the comments about $299 being a pretty good deal truly makes me laugh. Ten years ago a system of such capacity would be > $50K and you're downplaying $299.
Grow some perspective.
This is the problem with low-low pricing. If Apple charged $40k, maybe all the "professionals" would be onboard!
I think it is great to see the simplification of the product line. FCE always seemed an odd product out.
This is the internet. People are more invested in their egos than in understanding each other, and since several people have chosen to put words in my mouth to attack me, there's no point in really trying to advocate for the product here. Let the haters have the thread, I'm out.

The music industry owns the music - and they're free to price it however they want. If you think the price is too high, your only legal and moral response is to not buy it. Not liking the price is not justification for theft.
Ah, but isn't that the heart of the matter - shouldn't you have the choice to be to go to another cheaper provider? At the moment we have expensive and free - no wonder P2P is such a success.

Does this rule apply to non Apple computers and tablets?
I recall only a short time ago when non Apple companies where posting numbers, people on these forums were ripping the figures to shreds as they said they were not sold items but only shipped items.
Do we all agree the same rules for everyone :)
How are those tablets working out for those companies? I'd say it's pretty much adhering to the "rules" as set out above. If all of their products sold as "well" as their tablets did, those companies would be purged. Not a double standard.

Obviously, it wouln't be "all at once" and these types of things never happen in one single "foreign land". But history is wrought with many resettling of peoples, the Jews is just one example. This actually happens a lot for "unnatural" disasters like war and stuff.
If this situation blows up more and more, heck, humans haven't even dealt with such a potential disaster outcome before. It's actually purely "unnatural" at it's roots. There isn't any natural deposit of refined radioactive uranium/plutonium/whatever that we've encountered on earth before. This is purely man-made and is not supposed to exist. I mean, what is there to do in such a case? I know GM, Microsoft, Motorola et al may have a field day if the Japanese just disapeared, but hey, there's added value elsewhere that many nations would value in having their human and physical assets close.
I've been observing this thread, and slightly educated from it too (thanks nuclear people!). But I had to jump in here - is this a joke? If it is you're taking it too far.

Once you start using it, you'll find that the Mac OS is a much more intuitive system, but you may have to unlearn the ways of the windows. With the Mac, the desktop paradigm is fully realised - so if you want to move something from one place to another, you do it just as you would in the real world, by picking it up and dropping it where you want it. Don't worry about opening the destination first, as the finder will automatically open windows for you.
If you want keyboard shortcuts on the Mac, go into System Preferences and select keyboard, then you can add/change as many as you like. To change the defaults - just double click on the existing one.
You can use smart folders on the Mac which basically perform a live search and update their contents automatically - this allows you to make a folder which contains any combination of files/folders/apps for any amount of time.
Also, as pointed out by others here, Shift select is the same as Windows and if you do Cmd select, you can select the first two files, miss out the next one then select three more etc.
Hope this helps, my advice is make the jump, you will not regret it.

One of my thoughts on why people follow a religion are that they were raised with it, so it becomes a tradition.
That would not be my word of choice.
Brainwashing or indoctrination comes closer to the mark.

This makeup of this forum's members intrigues mean slightly. Why are most of the posters here Atheists? Is it part of the Mac using demographic, the Internet in general's demographic, or are Atheists just the most interested in Politics, Religon, and Social Issues?
A possible reason is that any time someone puts forth a theistic belief they get mocked, trolled, laughed at, ganged up against in threads, etc. The overall PRSI attitude of "religion is wrong, the only way to go forward or intelligent is to become free of religion" probably does not help any.
I do not bother actively putting forth my theistic beliefs because I have absolutely zero desire to waste my time arguing with people I will not ever meet in person. Not to mention I do not waste time arguing over anything - I wil have a discussion fine, but 99% of online "religion" threads are not discussions but rather a "you are wrong LOL IDIOT" fest. No thanks.
I have personally thought through my beliefs extensively (likely more and more frequently than most of you have thought through your respective beliefs) and have no need for someone else to tell me I have not or am mindlessly following a system I grew up in or am less intelligent. Especially considering I am not mindlessly religious, I did not grow up religious, and according to all standards of the USA I am quite intelligent.
