Switching off or turning down UAC in Windows also equally impacts the strength of MIC (Windows sandboxing mechanism) because it functions based on inherited permissions. Unix DAC in Mac OS X functions via inherited permissions but MAC (mandatory access controls -> OS X sandbox) does not. Windows does not have a sandbox like OS X.
UAC, by default, does not use a unique identifier (password) so it is more susceptible to attacks the rely on spoofing prompts that appear to be unrelated to UAC to steal authentication. If a password is attached to authentication, these spoofed prompts fail to work.
Having a password associated with permissions has other benefits as well.
If "Open safe files after downloading" is turned on, it will both unarchive the zip file and launch the installer. Installers are marked as safe to launch because require authentication to complete installation.
No harm can be done from just launching the installer. But, you are correct in that code is being executed in user space.
Code run in user space is used to achieve privilege escalation via exploitation or social engineering (trick user to authenticate -> as in this malware). There is very little that can be done beyond prank style attacks with only user level access. System level access is required for usefully dangerous malware install, such as keyloggers that can log protected passwords. This is why there is little malware for Mac OS X. Achieving system level access to Windows via exploitation is much easier.
Webkit2 will further reduce the possibility of even achieving user level access.
The article suggested that the installer completed itself without authentication. I don't see how that is possible unless you are using the root account or something. It would give sudo access, but even still you'd get SOME dialog box :confused:

A significant amount of multimedia related software already will use more than two cores and can be run simultaneously to easily hose an 8-core Mac Pro now.Well a significant amount of 3D and video software currently uses more than 2 cores but that's still a very small segment of the overall computing market. The multi-core market can't be ignored, I'm not saying it should be, but it's still not going to appeal to the masses until the rest, the majority, of the software out there catches up.
Quad core imac's would be pointless right now but maybe they wont be in 6 months if software catches up. It's pretty clear that hardware is ahead software at the moment but it will catch up again. It's gone back and forth for as long as I can remember.

Ummm.... everyone that's into gaming HATES Activision.
Yeah that is why they have the top selling game on console in COD and the top selling game on PC in WOW :rolleyes:
That being said, I would love to see games like the old school RPG FF games or even starcraft type games.
Those would own on the ipads and work pretty well on the iphone/ipods as well

You do recognize that there is not currently an HD system in place from Apple. If HD streaming does work, and I'm certainly not convinced of that at this point, you still have to shoehorn the entire system. The content you purchase from iTunes is not in HD and probably won't be for at least a year, probably 2-3. Therefore, the only HD content will be content that you added on your own, via 3rd party solutions.
So enjoy your patchwork HD system, I'd prefer something more seamless, and supported by Apple.
I am a video editor. All the content I shoot these days is High Def. My client's video is high def. The personal movies I take of my kids are high def. I edit them in either Final Cut Pro HD or iMovie HD. I use a dLink 550 now to stream high def to my 27 LCD monitor.
BlueRay disks are soon to be high def. The iTV will handle High Def via ethernet at least.
High Def Broadcasts exist right now in SLC.
Not sure where you are at with all this but I view a lot of high def content.

Right, but how is that not a fad? By definition, it doesn't matter how said fad ends, it simply means that it's overall existence is temporary.
I agree that it it was replaced by newer technology that does more, but it still was a fad in the end.
By that definition, the internal combustion engine is nothing but a fad. I think maybe you're just not familiar with what the word "fad" actually means Check it out: http://dictionary.reference.com/browse/fad

I was assuming this "family of four" included younger kids (possibly one age 4 and one age 9). ...They do watch a boatload of TV. Between the two of them they could easily watch 8 different series.
Now for the parents...
I would assume they each have one or two daily show(s) that they like to watch (which is where I was counting most of the monthly cost). For example, "The Daily Show" is $20 a month multiplied by 3 different shows, equals $60/month. Plus, it would also be expected that they should watch a few series (probably at least 5 between the two).
Perhaps it was a exaggeration, but I think I proved my original point that buying your TV shows from iTunes could easily exceed your monthly cable bill (maybe not for a single person, but once you get a whole family watching TV, it isn't that hard).
...Plus, how do you get your local/national news and sports shows? ...and no, news & sports "highlights" from iTunes don't count.
Dude. If this is your family, you need to be watching less TV and getting outside more. Or at least stay inside and play board-games with the kids. It's much more fun than vegging out on the couch.
geeze. Yeah, if I watched that much TV, I'd be complaining about the iTS too!

It is safer to run under an administrator account all the time in OS X than in Windows. On Windows, the administrator is almost the equivalent to the root account on *nixes and as such has unrestricted access to any and all files on the system.
Windows Vista & 7 have the UAC - meaning that admin accounts are effectively the same as on *nix & OS X.
It works well (on Win7)

2. Many programs want you to manage files from within programs. Itunes does not want you organizing music folders. It wants you to organize in itunes. iphoto is the same. You just have to let go of folder management...except for documents. Its a hard habit to break. Let the programs do the organization.
You can easily elect to manage your music files yourself, rather than have iTunes do it. That's the method I prefer, as my organization is better than theirs. All you have to do is uncheck the following boxes in iTunes Preferences:

Do you have evidence of this just out of interest? I too was surprised to read this, so I'd be interested if you had evidence the other way.I wonder if they mentioned the fact that Dell has made the computer a disposable purchase with their $299 PCs. I'm serious people buy a new Dell every few years because they are garbage. Do you honestly think people give them back for recycling. They sell them on ebay or craigslist, and the new owner after about a year puts them in the dumpster. With Apple people keep their machines much longer, and are much more likely to recycle them because they are smaller and easier to take to a recycling center (no CRT). This alone makes Apple greener then Dell.

Oh yeah, it's definitely trending downward now instead of still climbing, but it took almost a decade before that happened, not 3 or 4 years as claimed earlier. And they still sell millions every year, which you cannot say about pet rocks. That's the difference between a fad and a popular product. In a fad, the sales dry up quickly.
I understand what you are getting at. I still personally feel it is a fad, and it is drawing to a close. But I alone can't label it as such. :(
Speaking of fads, when will the current craze if wearing HUGE face covering sunglassess end? :cool: :p

OK. I know that many of my apps aren't going to take advantage of this level of multithreaded power, but I can't help but get excited by this development. After so many years of sluggish improvement, it feels like we're in the midst of rapid (and radical) change.
Each process is it's own thread. And most processes have multiple threads. Unless you only always have one program open at a time, more cores always can help speed up your system.

Yeah I know. So are you thinking the Dual Clovertown may be a dog 'cause both sets of four cores have to share one bus each? If it won't really run faster what's the point? I hope that isn't going to be a problem for "simple" video compression work which is all I want it for.
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.

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?No thoughts. Hope for the best.

Im definitely ready to upgrade to a new Mac Pro, top of the line..
The fact that the OctoMac could be released anytime between Black Friday and MWSF is really making me anxious..
I fear that they hold it till MW.. and I jump the gun and buy a Quad. I mean Im using a Powerbook 1.67.. and multi-tasking like crazy.. The upgrade is a must.. sometimes Im running Dreamweaver, Photoshop, Illustrator, Itunes, Azureus, After Effects all at the same time.. Obviously as soon as I render, coffee break!
The quad would still kick ass.. Octo would pave the road ahead.
Keeping my eyes peeled on any indication of the TBA Octo. :cool: Post 163 (http://forums.macrumors.com/showpost.php?p=2994404&postcount=163)
Running a bunch of apps simultaneously and switching around is not a multi-threaded workload but is multi-tasking. The Multi-Threaded Workload is like when you start rendering in one, then switch to another and start rendering there, then switch to another and start crushing video, then switch to another and start crushing another video with the second application of two needed to get it down to high quality mp4 like for example how I use Toast followed by Handbrake to first create high quality DVD Images then crush those further to high quality mp4 with Handbrake's 2-pass FFmpeg encoder. Toast can use up to all 4 Quad Mac Pro cores and Handbrake can use almost 3. I hope to God they still function properly on the Dual Clovertown Mac Pro.
This would not resemble the workflow you exercise with a 1.67GHz PowerBook G4. You would be doing things in quite a different way with 8-cores at your disposal. But it does depend on how much you want to use multi-threaded applications simultaneously and as warned above, that what you use will not fold in the face of reports to them that there are more than 4 cores on board due to software authoring mistakes.
