Just another reason for people to use Firefox. Safari is bloated in my opinion anyways.
But regardless, this is hardly a threat and I don't see what the big deal over it is. From what I can tell, this malware is downloaded on user error. Not only do you have to have Safari open "safe" files, but you also have to visit the site in order to download it, which by now I assume Safari will warn you about anyways.
If this is the result of computer geniuses trying their attempt at a Mac virus, then I'm not worried about the future security of my Mac at all.
In addition, you have to click through an installer and enter your password then enter your credit card :rolleyes:

And for the record, of the 12+ Apples and 3+ iPods I've owned, I've:
1. Donated my 1994 Apple Performa (?), of which I got a lot of mileage out of, to a company that fixed it, removed my data for me, and gave the computer to women who were abused.
2. I've sold all my other Apples to new owners who used them for school, work, etc.
3. I have an old Power Book I sold to my old roommate, whose new roomies dropped it (and his new PC notebook, whoops), and I have it back. I may just sell it to an Apple guru who can repair and use it.
4. My old iPod (Gen 2, 2002) is about to become a special OS X bootable disk; my wife's mini now belongs to her Dad; my other iPod (gen 3 or 4--last black and white one) my wife uses; and I love my iPod video.
No need to throw any of it away, no need to recycle it if others can use it, and I can take the money and buy new Apples or pay some bills, etc.

I share your very pro-mac attitude, but it IS pro-mac to call a spade a spade. I hate to admit it too, but Wintel is getting faster and faster and we're sitting still.
OS X is an amazing Unix based os that should Scream in every app, and yet Wintel is kicking our buts in 3D graphics which should be a mac relm. Instead of blindliy saying that Mac is best we should self examine and send Apple our opinion via their feedback on their website.
I know that people hate car examples so I will use a totally different one. War history.
Hitler was not only an evil Nazi facist, but he was once a corporal and knew little or nothing about war tactics/strategy. He had some of the greatest generals of the 20th century working for him. Field Marshalls Von Manstein, Von Rundstedt, Rommel & ColonelGeneral Guderian but to name a few. Read up on military history, these were great leaders of fighting men, and Hitler was a politician.
They constantly told him that he was doing things wrong and he just refused to listen, to the point of firing all of them at one time or another for telling him The Truth Now, granted, we are better off that Hitler lost (those Generals themselve were even happy about it) but that proves that you gain nothing by denying the truth.
now back to Apple. Apple is only gonna make machines that are faster than Intel (i.e. G5, G6 etc...) if we DEMAND it. If we are content with 800MHz note books, while IBM makes 2.0GHz and Alienware makes 2.6GHz ones that smoke us, then we are doing ourselves a disservice.
I am a dedicated Apple user, but only because of OS X, until OS X, I was a Windows guy and wanted an Apple, becasue back in 2000, the G4 was the top. I figured that between the G4 and Unix, I was gonna be top. But Apple has stood still (compared to Wintel) and I am starting to get anxious, and so are others.
there, I've said my $.02............can we still be friends?

That sounds like an ad hominem attack against Nicolosi. I agree with him and with his coworker who gave the lecture.
On what basis? Solely because it confirms your prejudice? Being gay has nothing in the slightest to do with gender identity, nor does Joseph Nicolosi's work have any standing of substance in the medical and psychiatric community.
What Joseph Nicolosi does is run a racket. He's little more than a grifter, a trait often found in religious circles.
For over three decades the consensus of the mental health community has been that homosexuality is not an illness and therefore not in need of a cure. The APA’s concern about the position’ espoused by NARTH (The National Association for Research and Therapy of Homosexuality) and so-called conversion therapy is that they are not supported by the science. There is simply no sufficiently scientifically sound evidence that sexual orientation can be changed. Our further concern is that the positions espoused by NARTH and Focus on the Family create an environment in which prejudice and discrimination can flourish.
In short, he's a fraud.

It auto-executes the installer because installers are marked as safe if "open safe files after downloading" is turned on.
This is not an example of shellcode being injected into a running application to execute code in user space.
A smart hacker will simply feed Safari the data it looks for when verifying a file is an installer. Once that's done, do what you want with the person's computer. It isn't rocket science, it just takes time and effort, something many hackers would rather spend on windows-based PCs.
EDIT: Because trolls will feed on anything, what i meant is that's what you'd have to do to run code without user permission. The code couldn't do much other than delete everything in your home folder but... Well, it can delete everything in your home folder. To be perfectly honest though, whoever doesn't back that stuff up is asking for trouble considering it doesn't even take malware to lose your data.

Are you sure that is the end of it, just having safe files checked and this thing installs itself? I'm trying to figure out where this is happening (i tested it myself and all it did was unzip the .zip file, it didn't automatically launch the package installer and then click the Install button for me).

Everything is hate to people like you. It makes it impossible to have any kind of conversation.
Difference of opinion != Hate
Putting homosexuality down to the choice of a "hip counterculture" is hateful, because it completely trivializes the issue.
Real people's lives are being snuffed out because of who they are; these are kids that will never get a chance to do all of the things that make this life so great.
Your words are hateful because they further marginalize. I am a heterosexual man, and I did not choose to be one. My best friend is a homosexual man, and he did not choose to be one. Yet he had to endure an unending fear of violence for who he was, and I did not.
I don't even care if you don't like homosexual people; you're free to do that. But don't trivialize the situation; these people are dying for who they are, and that should shock and disturb every last one of us.

I have absolutely no idea what people complaining here about it going non-pro is talking about.
Did you even watch the coverage? Or did you just look at screenshots?
Some pro-style questions that have been left unanswered:
What about XML and EDLs in and out of FCP X?
What about multicam and multi-clips?
Can I turn the �magnetic timeline� off?
Can I turn all the pre-processing that happens on ingest off (if I'm intentionally shaking the camera I *don't* want FCP to auto-stabilize it)?
How does media management work?
Is there a Media Manager tool?
Can I remap the keyboard?
Is there a better title tool?
What about multi-user environments?
Is the app as mouse-centric as it appears to be?
Are all settings global or can I have project specific settings (such as telling FCP that the capture scratch for Project A is in folder A and the capture scratch for Project B is in folder B)?
I could go on but I think I've made my point. Now, all of this stuff is pretty mundane to cover the first time they show off the app so I'm not surprised it wasn't mentioned. FCP X still has a lot more questions than answers right now, IMO. I can't wait to learn more about it though.

Android is to Windows, as iOS is to Mac OS.
The similarities are astounding � Google is doing the same thing Microsoft did back in the day.
As much as Apple cares about marketshare, the experience is more important to them then the product itself. That's really something.
Nonsense - Microsoft did not give away Windows for free, and certainly never gave the source code to OEMs to develop in their own way. Windows Phone 7 is to Windows...and that's about it. There's no point in even trying to make this comparison since Android as a platform is not as prolific as iOS anyway, is HORRIBLE for use in the enterprise (blackberry is the real competition there), and is also used on phones that aren't even capable of running apps.

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.

Agree. Too bad the iMac never took off in the enterprise sector. I remember when I was going to the university in the 90's I saw plenty of macs all around campus. Now the times I've gone all I see are Dell's, and HP's.
The iMacs are taking off the issue has always been support. Apple gives terrible enterprise support and fake roadmaps. It makes it very difficult to justify buying a machine that costs twice as much and comes with zero support.
Doesn't matter to me though I still order them for my clients like crazy.

Yes, that was exactly my point. The people who know how to use the software are (sometimes) assistant editors, although I find the vast majority know how to do a few simple things, but do them well.. The original poster was implying you needed to be a hollywood film editor to judge technical capabilities, and I was saying they were the worst choice for just that reason.
The people who know the most about editing systems are the Sr. editors who work on heavy, effects based sequences that work in broadcast production environments (I'm not talking about me here). *They* are the ones who push systems to the limits and *they* are the ones who go to NAB. (They're still only 10% of that room)
I think that most of them will find that Apple has, at present abandoned them. That's not to say the industry won't shift, and there won't be enough 3rd party solutions out there, but they are throwing Avid a HUGE bone here.
FCP was making big inroads into broadcast, and they're throwing it away-- for today certainly.
Filmwise, could go either way, depending on the production. If it's got great RED/4k performance, "film" support isn't so important..
But for the indie crowd, they're really screwing them over, if they are abandoning Color. *THAT* is what shocked me. I'm also surprised that effects weren't more advanced. I couldn't see anything on a titling tool, but that's pretty imporant for Broadcast as well.. and *no* existing solution is good for that... They really had (have?) a chance to make that right, and it seems they don't care.
So, when I say "iMovie Pro" that isn't necessarily pejorative. This product is WAY, WAY, WAY more iMovie than FCP. That doesn't mean you can't cut "a real movie" on it. But for Broadcast TV, it's a real step down in a lot of ways-- at the very least not a step up.. The interface is very iMovie. They should have called it iMovie PRO, especially if they're getting rid of the rest of the FCS apps..
Now if it turns out this is just the tip of the iceberg-- then we really could be in for a treat.
Who said anything about discontinuing Color and the rest of FCS? I can't imagine Apple would think that Color could be replaced by one-click color correction. And once and for all, can we stop saying that making the interface easier to use is making the product less professional? Is OS X less professional than DOS?

Yup, I agree. companies need to expire their annual budget by Q4, so they're just lookin' for things to buy at that time. I saw it all the time at Xerox. The account rep's would scrape and scrounge for sales for the first 9 months, start getting easier sales in October and November [since it's Q4], and then they ould just sit back and wait for sales to come to them from customers that [i]had[/b] to buy things before the end of the year and spend their remaining allocated budget, otherwise their budget would get cut for the following year.
Maybe for Easter we'll get Adobe CS3 in a colorful egg or frilly basket. :rolleyes:

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)

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)

Tonga (thousands of miles away) was just hit by a magnitude 6.1 earthquake. Eerie coincidence. And there was just another magnitude 6.8 aftershock in Japan. :(
Open your wallets for this one. Unlike Haiti, the Japanese government won't waste the money, and it will do some good.

You guys lost me and prolly (I like that, Prolly) about 90% of this forum....
have fun, and lets see how many pages you can get this thread to go to? I predict, 12.

FBDIMMs are designed for maximum bandwidth, not for best possible latency, so they cope with this better than any other kind of memory. You may read that bandwidth is the bottleneck for these processors. However, that is only the case for pure copying operations. Code that calls memcpy () on all eight cores simultaneously will run out of steam quite quickly. However, most code does actually do some work with that data (like video compression), and the bandwidth won't be that big a problem.
Lets say you compress a two hour dual layer DVD with Handbrake at 1 Megabit per second. DVD = 9.5 GB takes ages to read from DVD, takes about two seconds to copy in memory. Copying the 1 Megabit takes two dozen microseconds. Most of the action will happen in L2 cache, so you should be fine.Thank you for the positive feedback. But I don't rip anything from DVDs much at all. I crush EyeTV2 broadcast recordings with Toast 7.1 (UB) to DVD Images on hard drives. Then I 2-pass rip from those images with Handbrake to mp4 so I'm not having any optical bottleneck at all. From what you say, this should be much faster like I'm hoping with all those cores.
