I have had ATT for almost three years now - and I haven't had one dropped call.
and obviously have either never made any calls or do not live in a major metropolitan city like NY.

lol, in all of the classical arguments for the existence of God, God was defined as being in the possession of the same attributes as he is in the Bible. If you could define God in any way you wished then I'm sure it'd be a lot easier to prove his existence.
The Bible, as you may or may not know, is the basis for Christianity, and the Old Testament is the basis for Judaism.
Hindu theologians take a different approach to these ontological problems.
The Bible? I don't think I've ever heard of it. :rolleyes: No one can prove the existence of God in any form, let alone some specific God as described in the Bible (a compilation of edited stories mostly derived from hearsay).

Chernobyl was 25 years ago and Russia was not very open to outside help ... no matter how bad this escalades ... somehow this will be contained.
Irrespective of that, given that the reactor design is not the same as Chernobyl an accident of that sort is simply not possible with these reactor types. Chernobyl was a supercriticality event, a runaway nuclear reaction which is a high risk in a high positive void coefficient design like the RBMK which uses graphite as a moderator and water simply for cooling. Loss of cooling in this design leads to a nuclear explosion due to gas bubbles being less off a neutron absorber than liquid and burning graphite along with it. BWR designs such as the ones in Fukushima can't go supercritical if coolant is lost. Thus an explosion and moderator burn such as the one in Chernobyl can't happen. As such, the worst case is a local loss of containment and core melt that can lead to moderate amounts of radioactivity escaping into the immediate local environment. A widespread contamination over hundreds of square miles is simply not possible. As such, the current news reporting is irresponsible spreading of half baked information and knowledge and nothing but fearmongering.
The same goes for some of the BS that is being posted about Germany's reactors or other reactors in western Europe for that matter. Western EU countries do not use RBMK type technology or other high positive void coefficient designs, the only ones that still do is the Czech Republic and a few other former Soviet countries and these reactors are being phased out and being replaced by modern LWR and other designs with western aid.

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

Can we talk about Greenpeace's environmental track record for a minute?
- They mourn the millions of gallons of gasoline burned by cars, but refuse to support diesel fuel, which, while slightly more polluting than gas, is nearly twice as efficient, meaning collective fuel consumption would be cut dramatically.
- They champion E85, which provides only about 70% of the efficiency of gas and requires nearly a gallon of gas to manufacture per gallon of E85.
- Ditto the above for hydrogen-based fuels.
- They've indirectly caused the deaths of thousands of starving Africans by preventing the development of genetically-engineered foods.
So who is Greenpeace accountable to?

Well it was rumoured for some time and we all waited with baited breath but was Apple seriously going to end the pro app that started them off to stardom? Sadly yes they have. What genius decides to make a pro app accessible to the masses? We who use FCP have to make money from our business, so we need a little bit of smoke and mirrors to make our business needed, otherwise our clients will just get a 16 year old in off the street, download FCP (sorry imovie Pro or whatever they have decided to call it) and there you go we are out of work!
I can see the business sense for Apple but they have now taken it all away from us who stayed by them for all these years.. Thanks Apple for the kick in the teeth. I am a ''Pro'' app user and have been for well over a decade and will be sad to move over to a new system but alas nothing lasts for ever.
RIP FCP
Born 2000 died 2011If a 16 year old kid getting their hands on your editing software is enough to put you out of business then you're probably already in trouble with or without this release. Also they clearly are still calling it Final Cut Pro, so nice try with that half-assed snub.

Poor thing... he doesn't realize napster and limewire are history. Also, once the data hits my device, it's mine to do with as I please. Thank you very much.
>laughing_girls.jpg.tiff.
By the way, I agree with you. Once you buy something, you should be able to use said device to its maximum potential. NOT have to pay to unlock its built-in features.
And by the way AT&T, all I want from you is a large pipe full of 1s and 0s. What I choose do do with them, or how I use and distribute them should be of no concern... Just one flat rate for a big, fast, data pipe.
Until then I'm stuck because I believe in playing by the rules, no matter how F-d up they are...

encourage[/I] people to be gay/lesbian/whatever. At the end of the day that's basically the underlying message in all these videos: "Go ahead, by gay. It's perfectly fine
...It's a very private journey and I'm not so sure that the media should be offering this type of "GO FOR IT!" message. One should come to accept who he/she is and embrace the inevitable consequences of the lifestyle.
I don't think anyone's saying "go for it!". The basic ideas I got from the video were:
-you're not alone if you're suffering
-life gets better, so stick around
-find help
I didn't really pick up on anyone saying, "You should be homosexual" or anything like that...

In Windows 7 you not only have the option to switch it on and off, you can also customize the intrusiveness of it, I find it much more user friendly than in OS X.
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.
So Safari auto-downloads, unarchives and auto-executes something, but you think it is safe because it's an installer ? :confused:
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.
I'm sorry, but I'm still curious about the "auto-execute" part. Why would it run the installer automatically after decompressing it. That sounds quite "unsafe" to me. Even without administrator privilege, that means code can still run that can affect the current user's account.
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.

If an artist isn't mainstream, I'll gladly pay for their music to support it. But since my musical tastes tend to gravitate towards major artists, I don't think twice when I torrent their albums.

The point is, it's Apple. It's where the entire market is headed. It's what got RIM, Samsung, Motorola, Microsoft, and other major players all worked up.
This isn't pokemon or some drug-addled actor.
It's what used to be a minor subset of the industry that is now breaking out and expanding rapidly. For one, it's mobile. The mobile market is massive and is experiencing nothing but growth. These tablet and pad devices are the next step in mobile computing, to the degree that they will supersede laptops and notebooks.

In truth the only real benefits are that Windows and Mac systems are faster and more stable than they used to be. For Macs to make any inroads more innovation is the key. They cannot compete on price/performance and never will. Moving to x86 could help of course. Note that most people don't buy Macs because of price and not because of performance issues.
So with this in mind if you set aside the small contingent that truly needs faster Macs for their jobs in professional settings, the Mac really needs lower prices and more innovation. Do that and Apple will have a winner that they would need to open up the clone market again just to be able to make enough of them.
Frankly this whole benchmark argument is stupid for most of the people here. Benchmarks should be used as nothing more than a guide and you should have multiple sources if you want to base a purchasing decision from them alone. Too many people treat them as the end all be all.
One point you are missing is that I can upgrade my PC 5 times over and still have the cost be lower than buying a new Mac. So a mac can run modern apps 5 years later. For the same price, I can get a PC, drop a new HD, video card, and CPU in a few years later and then end up with a leading edge PC, and not a bleading edge mac. My B&W G3 isn't even upgradable to the speeds of the current iMacs. With a PC a new mobo and CPU will get me into whatever is the current CPU class....

AppleInsider claims they have confirmation (http://www.appleinsider.com/article.php?id=1877) that Apple will be using Intel's Xeon 5100 series processors, also known as "Woodcrest" to power their next generation Intel-based Mac Pro Workstations.
Previous claims (http://www.macrumors.com/pages/2006/06/20060609094241.shtml) indicated that the Mac Pro would continue the Quad-core tradition set by the latest batch of PowerMac G5's. However, in order for an Intel-based "Quad" to be developed, a multi-processor machine would be required, which inherently leaves out the use of Core 2 Duo "Conroe" based microprocessors, as they do not support multi-processor configurations.
Of note, ThinkSecret has maintained (http://www.macrumors.com/pages/2006/07/20060704122932.shtml) that they believe the Mac Pro will utilize Core 2 Duo (Conroe).
Additionally, AppleInsider speculates that Conroe may be used in a future iMac revision, while Merom will be used in future MacBook Pros and Yonah will remain in the MacBook and Mac Mini.

No, a merger by acquisition which would result in a merging of the Wii and Apple TV of course.
The problem with your view is that Nintendo is a JAPANESE corporation and they are still the boss over the USA counterpart. Apple has to kiss Japan's ass first to do that. I heard a very old story from the 1990s that Microsoft tried to buy them out which Nintendo of Japan's CEO, at the time, discussed and revealed in an interview.
Guess what? Nintendo of Japan gave Ballmer the finger. Secondly, Nintendo and Apple could partner up in a deal, theoretically, but a buyout will never happen. And no, the Daimler/Chrysler situation is not a good comparison for this industry.

The Quadro in the WMCE really puts up a superb 1080p picture - not sure that I'd want to compress the signal and send it over wireless...
Technically you're not compressing the signal. Just the file (which will be cached if the network can't cope). The signal is produced locally.

Run an RGB to CMYK conversion on a 1 Gig Photoshop file with embedded profiles -- watch activity monitor. See that all four processors kick in for this processes. Many Photoshop processes efficiently use all four processors.
Just wanted to note...
It is easy to confuse a single thread bouncing among available cores as it gets scheduled (which happens easily on Mac OS X) and multiple threads executing in parallel on multiple cores if you look at per CPU utilization graphs because of sampling artifacts.
In top you want to look at "CPU usage" or in activity monitor look at "% Idle". If idle CPU usage is close to zero then you are truly utilizing the cores in your system which often implies that the application you are using is spreading the work across the available cores. In a four core system if idle CPU is around 75% (usually several percentage points under that because of system related threads supporting the application) then the application is really only using a single core (single threaded). In a four core system if idle CPU is around 50% then the application is really only using two cores (two threads). etc.
You can also look at load average in top. If the load average is around 1 then the work load on the system is on average only utilizing one core. If the load average is around 2, then on average two cores are being utilized. etc. If the load average is greater then the number of cores in the system then the work load is greater then what the cores in the system can run concurrently.
Note load average (and CPU %) will be depressed if the work load is IO bound and not CPU bound... so an application could be attempting to utilize multiple cores (use multiple threads) but IO bandwidth, etc. is starving those threads of the data they need and hence preventing them from executing.
The best way to know that an application is utilizing multiple threads for a task is to use tools like sample and Shark.

Apple's point is that your computer more or less has that capability (ok with an Elgato dongle), and in any case they don't want to follow that business model. I guess you're not the target audience.
Only time will tell if anyone buys this.
I think the focus should be on the business model than the "you can always use a computer". Apple is reinventing TV. If you assume that an iTV user will be downloading pretty much everything they watch, then a DVR just becomes redundant.
Indeed, I think the lack of a DVR tells us a lot about Apple's thinking. It would certainly help shift boxes in the short term if they made a DVR an option, but in the long term it would essentially mean Apple would be shouting "We're co-existing with cable."
Of course, at this stage, it's too early to tell. For all we know, iTV will be launched in January (1G iPod 5Gb), and then in April we'll see it replaced with three variants (2G iPods - iPod 10Gb, iPod 15Gb, iPod 20Gb), one with more disk space, one with a DVR, and one that integrates with CableCards. I don't see them doing that, but I'm less certain of that than I am of them not releasing an iPhone.
Only time will tell if anyone buys this.
I think the focus should be on the business model than the "you can always use a computer". Apple is reinventing TV. If you assume that an iTV user will be downloading pretty much everything they watch, then a DVR just becomes redundant.
Indeed, I think the lack of a DVR tells us a lot about Apple's thinking. It would certainly help shift boxes in the short term if they made a DVR an option, but in the long term it would essentially mean Apple would be shouting "We're co-existing with cable."
