Ultimately, yes - that's probably the only realistic solution AT&T has, and they *are* adding new cell towers all the time. I got SMS messages a couple of times announcing new ones they put online in my city, over the last year or so.
But there's a technology battle here they're on the losing end of, as well. The CDMA network providers have an advantage automatically, because the frequencies they use penetrate structures better than the GSM network frequencies used by AT&T and T-Mobile. (Note that T-Mobile was the other carrier with equal customer dissatisfaction to AT&T in the bar graph ranking that metric.)
I have Verizon and I think I've had two dropped calls in years.
AT&T really needs to get more towers up, that's the only solution in my mind.

I wish we could get more details then "it could be released after mid-November.." OF COURSE it will be released after mid-November, but what does that mean? End of November? December? January? I just want to know when it will be out!!
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)

Here is a list of privilege escalation (UAC bypass) vulnerabilities just related to Stuxnet (win32k.sys) in Windows in 2011:
Vulnerabilities are found in everything. It's not like sudo, RBAC or any other Unix scheme that's similar to Windows' UAC/RunAs has been vulnerability free all these years. This is besides the point that UAC is not somehow inferior. It's just an implementation of limited privilege escalation, same as you find on Unix systems. "Unix security" is not being any better here.
Provide an example of malware that only includes user level access being used in the wild as per your description that can not be prevented with user knowledge?
Have I claimed such a beasts exists ? No. Why should I then be made to provide an example of it ?

The Hebrew god is the same god as in polytheistic days, but once he had conquered all his fellow gods, he was left with unrivalled power. The Hebrew religion became monotheistic, and their new old god acquired sole power, but the root of the deity was no more or less than a shared and ancient mythology.

I've never encountered discrimination of LSBT in ether Scotland, Germany, or Thailand. But i did encounter it a lot in the USA it was very surreal and with my partner living in the USA just now studying i hear he gets bullied a lot in college just for being transgendered which is just absolutely crazy and he'll is glad to coming back to Europe in the next few months.
This is a real issue i feel that needs to be tackled in the USA as before i went i had assumed that people would be a lot more open there than they were.

Ugh, just as soon as I had posted...
I haven't "been praising" their construction, I "praised" their construction in one post, if you can even call it that. The Japanese know what they are doing by and large in many of the things they do; that's why Japan has had 30% of its power delivered via well-developed, and well-understood nuclear sources for years, while the west is still outright paranoid of so much as a mention of the word nuclear.
The only thing I did was compare it to Chernobyl, or rather defend against it, as it certainly is not Chernobyl, and was built to higher standards than anything in the USSR during that time, that meaning Chernobyl.
You think they built the plant 40 years ago and have done literally nothing in terms of maintenance and/or upgrades since that time? You don't think regulatory statutes and codes have changed during the time, and they've had to comply with those and be subject to normal regulatory inspections that meet todays 2011 safety and energy protocols?
Just because the plant was built 40 years ago, doesn't mean it is the same plant as what was built 40 years ago. Trust me, I was and am full aware that the plant is older than Chernobyl. But the difference is that Chernobyl ate it during a time of 1980's USSR safety standards, when the international nuclear community wasn't nearly as effective as it is today. Today's plant may be 10 years older than Chernobyl, but it's 30 years further up to date. Nuclear plants in the first world don't exactly get the "build it and forget it" treatment.
I don't want to argue about this, because it's pointless since we are all hoping for the best and fearing the worst. But I do know a thing or two, and it gets tiring correcting false information proliferating throughout thanks to a bunch of people in the media who have no technical training and haven't a clue about anything. The Japan forums are ablaze with misinformation.
Nuclear power is generally pretty safe, and it's a shame the west hasn't been able to embrace it, IMO. That isn't to say tragic accidents can't happen, as they can, but by and large they are extremely, extremely rare.
Not entirely sure with "the west hasn't been able to embrace nuclear power." France are the global leaders in nuclear power in terms of how many nuclear plants there are in France, and how much electricity is being generated in the country through nuclear energy. powering something like 80% of the country's electricity. And The French EDF corporation has operations worldwide.
More importantly, there have never been any severe deathly occurrences with nuclear power plants in france since a long time, and with the large number of plants they have (59), that's impressive.
Nuclear energy is substantially better for the environment, countries like china however continue to use coal as they main source of energy because they have tons of it and it's cheaper than making the foray into building nuclear plants. Which inevitably results in poor air quality all over the country.

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.

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....

One thing puzzles me though - the iTV is not a complicated piece of kit, hardly any more so than the mini or any other Mac. So, why did Apple pre-announce earlier this month for release early next year, and not release a finished product?
Well, perhaps it is complicated. I'd imagine the software side in particular will need a lot of work. If, as promised, it supports all of Quicktime, then there has to be an environment capable of running Apple's core QT code. (I'm finding it unlikely there's a full version of Mac OS X in there though would be delighted to be proven wrong.)
I don't think all the pieces were ready. At the same time, I feel Apple needed to promote it as early as possible. It wasn't clear where iTunes was heading and the number of people who want to watch movies on their laptops and iPods is so comparatively small, I think most studios didn't see a point in supporting the system. They had to announce iTV, if only to tell the studios they're serious.

Well, only if you insist that yours is the ONLY What about the denominations that say "Here's what WE believe, but if someone believes something else, that's fine?"
That depends on what "that's fine" means. I don't want to coerce anyone into believing what I believe. Others are welcome to argue for what they believe when they agree with me and when they disagree with me. If you know that I'm mistaken about something, I you to show me that I'm mistaken about it because after you do that, I'll replace my false belief with the corresponding truth that you proved. But if "that's fine" implies relativism about truth, that implication is not fine, because relativism about truth, or at least some versions of it, are self-contradictory and every self-contradiction is always false.
Many atheists deny that God exists. Maybe they're right, but their denial implies that theism is either true or else false. If those atheists say that theism is nonsense, what do they mean by "nonsense?" If they mean that theism is neither true nor false, then they imply their denial is neither true nor false, since theism is the belief that at least one God exists, and "There is no God" is the denial of theism. By the law of the excluded middle, every proposition is either true or false, but not both.

Here is an easy way to explain it. You can heat a slice of bread in a toaster and a microwave oven. Are you going to say microwaves compeat with toasters now. When they do not heat bread the same way.
That's a tough analogy, as it's true... microwaves and toasters can coexist. (Although, I don't have a microwave. It does strange things to pizza.) Yet, I don't think it's the same in the gaming world. Are iOS games really so different from other video games?
The only thing really lacking is a decent controller. There are so many ways to resolve this.
Example... put a motion sensing camera on the Apple TV. That $100-$150 box could be used for FaceTime and video games. I think that would be very popular.
Another Example... the remote control for the Apple TV could be expanded into a controller.
Yet Another Example... one iOS device can be used to control another. This technology is already in play.
I can't see how Apple making a Bluetooth controller, which, say looked a bit like a PS3/360 controller, and selling it as an optional accessory could be in any way a negative thing.
The negativity that I see is if it's an unsupported accessory. What if customers don't go out and buy it? What if developers don't modify their games to support it? There are lots of failed game accessories out there. While I doubt Apple will release the next Nintendo Power Glove, a goofy looking controller � like the PlayStation move � could be harmful to iOS gaming.

I think Apple's done a pretty good job, at least from a non-insider perspective. And the fact that they are exteremely open and friendly sharing their environmental information (http://www.apple.com/environment/) is something to consider as well. It is not always easy for the public to find out about a particular company's information from their website.
Obviously, though, Apple is a corporation, and, like most others, they will many times sacrifice environmental standards to save costs. All major companies (at least in the U.S.) do it�no matter how 'hip' or 'environment-friendly' they may seem. It's an outcome of consumerism.

I honestly have no idea how you have the job that you do, because you fail tremendously in this aspect.
I have the job that I do because I know MUCH more about Windows than you do obviously. If you think what I posted above is a bunch of fud then you really don't know anything about Windows OS or manual malware removal. There is all kinds of ways malware can hide and on Windows many times the only way you know its on the system is by finding altered registry keys, but removing the key doesn't remove the malware so you have to manually dig for files. Most of the time you can find them by looking but some malware uses the feature to hide folders completely even if you tell the system to show all files. If you want a prime example of a virus that does this look up and infect your system with Oboma (yes its spelled incorrectly). It went around our workplace all the time and most of the time it used the file hiding technique mentioned above. Another is WD32Silly (or something close to that). Thats another one that always did it. With over 6,000 users to support I see this stuff all the time.
EDIT: This is why tools that access files outside the OS are popular, like BartPE and various other packages. You can see these files if Windows is not booted up and your not plugging the drive into another machine.
Why do they allow the files to be hidden?
Of course if you used Norton you wouldn't have this problem. :D:D:D
Actually....we use Symantec which is the the first scanner we use which doesn't find anything ;) Or, to its credit it will find something, but not remove it (hence how we find out the names half of the time). Honestly though you really want multi-layered scanning. If the program on the computer doesn't catch anything it goes to IT and we scan it with other tools, as a last resort we will manually remove it but if it doesn't work or ends up being to "messy" the machine gets re-imaged.

ddtlm,
I have my theory as to why java took the lead over C in the sqrt example. There is quite a common misconception about Java that it's always slow, and there is a reason for it. Back in the early days prior to 1.2, it wasn't uncommon to see something like we did here run 10,20, or even 30 times slower then C. VM's today (1.4 /w hotspot) are much smarter than they were years ago. IMO, Hotspot makes the conventional "just in time compilers" look like a thing of the past.
Anyways, when you really think about it, Java really has an extra card up it's sleeve. Sure we tell GCC we want max optimizations, (03, etc), but GCC is limited to compile-time optimization. I think since java has adaptive runtime optimizations, specifically hotspot, the runtime optimization is what really makes the difference.
The reason why it's called "HotSpot", is literally because it looks for "hot spots" by profiling on the fly at runtime. Pretty cool, huh? Your first adaptive optimizations kick in second time the loop is ran. Not to mention the conventional JIT optimizations... code will natively compile and so you eliminate the costly overhead of bytecode translations.
Lastly, I am going to do the matrix operation you spoke about, I have to finish up some course work, so I may not get to it tonight, but as soon as I can devote some time to it, I will.
I have my theory as to why java took the lead over C in the sqrt example. There is quite a common misconception about Java that it's always slow, and there is a reason for it. Back in the early days prior to 1.2, it wasn't uncommon to see something like we did here run 10,20, or even 30 times slower then C. VM's today (1.4 /w hotspot) are much smarter than they were years ago. IMO, Hotspot makes the conventional "just in time compilers" look like a thing of the past.
Anyways, when you really think about it, Java really has an extra card up it's sleeve. Sure we tell GCC we want max optimizations, (03, etc), but GCC is limited to compile-time optimization. I think since java has adaptive runtime optimizations, specifically hotspot, the runtime optimization is what really makes the difference.
The reason why it's called "HotSpot", is literally because it looks for "hot spots" by profiling on the fly at runtime. Pretty cool, huh?

I have a couple problems with this approach. There's so much attention brought to this issue of specifically gay bullying that it's hard to see this outside of the framework of identity politics.
Where's the videos and support for fat kids being bullied? Aren't they suicidal, too, or are we saying here that gays have a particular emotional defect and weakness? They're not strong enough to tough this out? Is that the image the gay community wants to promote?
Man, being a fat kid in high school. That was rough. There were a number of cool, popular gay guys in my school. I'm sure they took some crap from some people, but oh how I would have rather been one of them! But hey, I'm still here, I'm still alive.
Bullying is a universal problem that affects just about anyone with some kind of difference others choose to pick on. It seems like everyone is just ignoring all that for this hip, trendy cause.
There's nothing wrong with focusing on a particular issue. The Japan tsunami is not the only suffering going on in the world, but people raise money and raise awareness about it cuz it wouldn't make sense to rally around "fix everything".
