Is anybody actually bothering to do this in the wild against any OS?
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?
Again, look, if you're not interested in the mechanics, that's fine. Stop replying to me.
My post is inquiring about the mechanics. For the past hour, I've been trying to find how this thing ticks by searching around for in-depth articles (none to find, everyone just points to Intego's brief overview that is seriously lacking in details) or for the archive itself.
If you don't want to take this discussion to the technical level I am trying to take it, just don't participate.
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.
I don't know of any other Web browser (this is not a OS problem, it's a Safari problem). that automatically assumes executables are safe and thus should be auto-executed.
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.
What does Webkit2 have anything to do with running an installer on the OS after downloading it ? That happens outside the rendering engine's sandbox. You're not quite understanding what this sandbox does if you think this protects you against these types of attacks.
Turn off "Open safe files after downloading" if you are worried about that type of attack implemented via "safe" files.
I think you missed the part where I don't use Safari. I'm pretty far away from allowing it to "auto-run" "safe" files (I choose what I want to run).
Again munkery, I appreciate you taking the time to respond, but I'm not some noob user. You are not answering my inquiries nor helping any here at the level I want to discuss this. I get everything you are saying. I've been getting that level for quite a few years. I'm trying to discuss at another level here. Do you want to participate or not at a higher level where we discuss the actual mechanics of this rather than just starring at the tip of the iceberg ?

And you can swap 'em right in. If Apple doesn't release a Mac Pro upgrade with some other goodies (I'm personally hoping for DDR2, as the 8GB of goofy RAM in my Mac Pro cost me an arm and a leg.) I'm just going to buy a couple quad core chips and toss them in my machine.

Good to know, since I'm not waiting till Q1 to upgrade. Could you elaborate on why you think that.
Because if it is 802.11n most new Macs would have been sold between now and when the device comes out.If the "new" Macs being sold post Sept. won't have a firmware update thats going to leave a LOT of potential customers out.
Simple matter of economics..

I do agree that it is effectively the break of a promise. Hell, it's the breaking of a contract... which is certainly quite wrong. But what if you believe the original terms and conditions to be morally wrong in themselves?
If you believe the original terms are morally wrong, then you should never agree to abide by them. Once you choose to agree to the terms, then you are morally bound to abide by them.

The cell phone market is so sporadic its hard to predict numbers for 1 year in the future, let alone 2 years.
Heck, new phones hit the market pretty regularly - I say at least monthly. Its a fast moving target.

no, i looked up real numbers and took off ~40% which is the amount apple would get off from retail prices.
+ if the low end mac pro has a single cpu if we are lucky it may have an empty socket ready for an upgrade.
If you looked up real numbers, post the real numbers. Based on the real numbers I've seen the price difference would be hundreds of dollars.
And PC companies are offering single woodcrest simply because conroe isn't shipping yet. Today, they have no other option for dual core. They might keep that config when conroe ships (for the few who may want that), but the conroe version will likely be hundreds less.
EDIT: Looking at Dell, so far they only seem to have woodcrests in server machines. They don't seem to be offering them in any config of desktop yet.

Nah. All those games you mentioned would be part of a pack of 25 on Nintendo for 19.99 like Namco museum.
Or would be part of a larger game as sub-games. Nintendo do understand this kind of gaming but package it differently. I am not at all convinced that that packaging & pricing strategy would not work on iOS.

And a nice Skype app that was able to send your private data out.
You apparently didn't read the article you quoted.
That version of Skype (since fixed) did not itself send any private data, which by the way, it has your permission to access.
It had a bug in the file permissions it used for caching contact etc info, which meant that it was possible for someone to write an app to look at it, since Skype didn't encrypt their cache files. There's no evidence anyone did so, though.
Kind of like how iOS apparently has a bug where our location history is available to anyone who writes an app to look at it.

By Quad you mean each slower Clovertown or a pair of faster Woodies?
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'm 99% sure the machine is intended as an independent hub that can use iTunes libraries on the same network but can also go to the iTS directly and view content straight from there (and possibly other sources, such as Google Video.)
You are going to be sorely disappointed then!.
The iTV most definitely requires a computer. The iTV is a like a suped up Airport extreme for video. It has already been demoed and it requires a computer. The computer streams the iTunes content to the iTV and the iTV receives the stream and translates it into video and audio out via an HDMI or SVGA connection to your TV. The iTV also supports front row and allows remote control of the iTunes source machine.
There maybe more features in the future but those are the reported and demoed features.

And it would never be pick up by the media. Like I said the media does not pay any attention to it and with out the media doing anything those groups can never get traction.
LGBT group yes are targeted the others it is hit or miss if the person is targeted. LGBT is going to be pick on pretty much no matter what. Fat kid may or may not be pick on. I have learned that humans are nothing more than things like chickens. That is if you put a chicken in a group with an injured leg the others will peck it to death. At first the injury might not of been a big deal but over time the extra damage adds up and kill it and the more it gets pecked at the worse it gets. All because it is different.
I don't agree. If those groups got organized, their message would eventually get picked up my the media. It's not like LGBT groups were started last weekend and, bam, the media picked up on it. It took decades for them to get to this point of media attention.
And I agree with Heilage: the message from the video doesn't only apply to LGBT folk.

Exactly. Numerous people have tried to explain that Merom, Conroe and Woodcrest basically are the same CPU, yet few people seem to have understood it yet. The differences between the parts are almost exclusively external (or atleast not related to the execution core), like socket and FSB frequency. The core architecture has even been said by Intel reps to be the same. The only reason for a Woodcrest CPU to perform better than a Conroe (the non-Extreme edition) would be because of the slightly faster FSB. This advantage could soon be negated by the use of FB-DIMMs.
So, why get so worked up over this?
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.

How many "page outs" per second does your system do? If you have enough RAM not many. Even those few writes DO go into RAM. There is likey a large RAM cache built into the disk drive. As for "page ins" they mostly come from your Applcations Folder, not the swap space. Mac OSX is smart enough to know that it does not need to write RAM pages to swap space if the RAM page contains only executable code. If you want to make the system go faster you would put your applactions in the solid state SATA so as to speed up page ins. But if space is limited a better way would be to put only the applactions you are currently using in the solid state SATA but to go even faster why not skip the bottleneck of the SATA interface and put the RAM that would have gone into the solid state SATA on your system bus. This is what modern computers do. They maintain a RAM cache of the disk(s). With the data (cache of the disk) in system RAM it need not even move. The OS simply does some "magic" with mapping registers and the data appera to move without need of any physical copy. A write to a register is more than 1000 times faster then moving data off a sold state SAYA drive.
The ONLY cases where a solid state SATA disk could improve performance is (1) if you have already maxed out the computer's system RAM and need to add even more. So either your Mac Pro is at 16MB or you imac is at 3GB and you need more. or (2) You have a huge abount of dta to process and you put the data in the solid state drive. This means the drive will be hugely expensive. Cheaper to use something like a SAN storage.
I snipped nothing.
The specific examples I refer to are putting applications in RAM, wherever that ram might be (ramdisc of main memory, ram based solid state drive on the drive bus, or memory drive on the graphics bus). Some applications greatly benefit from residing in RAM, such as compilers or image manipulators. Photoshop uses alot of swap space so you would need large ramdrives to benefit. I mainly am an advocate of ramdrives and see them underused in applications that would clearly benefit. Apple could gain some marketing points by simply offering such an option then bragging about it on TV of how a Mac is 20x as fast as a (stock) Dell :)

It's not "up to each person to decide, and make true in their own lives." God either exists or not; full stop. Even if it were "up to each person", how does telling other people that they will burn in hell for their beliefs fit in with this? If it's a personal thing, then KEEP IT PERSONAL.

I can't really decide what to think of an 8 core mac pro.
Right now FCP barely uses all four of mine.
It seriously seems that they a) haven't updated software pending an OS update, ie; leopard, to take advavtage of them or b) more cores really only helps the multi-tasking.
In any case I think my mac pro isn't quite as fast as it could be sighting the activity of my cpus during a render.
HDV render = 60% on every core. WTF?

I'm not going to worry about it. I know I need more cores period. I am going to be a customer so that money can go toward further progress in the development of multi-core processors and Macs. I am not going to wait and see how it goes for someone else. When you know you need more cores and more cores finally hit the street, you don't go "wait! this is uncharted territory with an inadequate FSB!"
No. You go "Intel knows what it is doing and so does
Apple. I will follow their lead and buy NOW.I think the FSB issue is over now. I've seen some preliminary benchmarks that dropped the FSB to 1066 MHz. 1333 MHz offered a little improvement. If you need MORE CORES, get them now.
