Next year you will see iPhones and iPods counted too. I mean you need to do all you can to make it look good to shareholders.
Apple just point blank told shareholders that last Q more than half it's profits came from the iOS devices. That is no secret. I would further argue that Apple shareholders own the stock because of the growth of iOS, not OS X. AAPL was a worthless stock until the iPod and all it's siblings took hold of the modern culture. Mac sales are just a bonus now.

cars may have produced 100x less CO2 forty years ago. but today there 100x more cars on the road.
Absolutely 100% false.
According to the American Automobile Manufacturer's Association, there were 169,994,128 vehicles in the world in 1970. As of 2001 there were 450 million.
Fine, then...per car, modern vehicles are now only 38 times cleaner than they were forty years ago. )

Oh well...Japan is history...
Time to start relocating the population and all their assets to Afghanistan. Didn't we find some ancient Buddhas there which the Taliban blew up? Well, we now declare that The Holy Buddha Land of the Japs! That MUST be were they originated from! They can even rebuild the nuclear reactors there too since no one gives a crap about that environment evidently. :p
Come to think of it...it wouldn't be too bad if Japan had to mass evacuate because of contamination. I mean, that place might eventually like blow up and flood at some point in the future right? It looks like it's on the verge of happening actually.
That would be pretty cool if they evacuated now. I mean, where would they go you may ask? I think they would mostly come the the US. I mean, we sort of helped them build their country up after WWII and we've always had pretty strong ties. Our economy is similar too.
Hey, we'll take Toyota, and Sony, and Mitsubishi...and heck, whatever can fit on the barges. :) I think it would be pretty symbiotic too as we use a lot of their crap anyway so might as well bring it all home. They have like the best manufacturing in the world and the US can use some of that today. We have lots of barren land all over the place that can be used for industry and Japanese ppl have the money to build here, rather than in the expensive cramped up island of theirs. Jobs for all! woot!

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.
Really,
Here is a list of privilege escalation (UAC bypass) vulnerabilities just related to Stuxnet (win32k.sys) in Windows in 2011:
http://cve.mitre.org/cgi-bin/cvekey....in32k.sys+2011
Here is a list of all of the privilege escalation vulnerabilities in Mac OS X in 2011:
http://cve.mitre.org/cgi-bin/cvekey....rivileges+2011
BTW, the system call for that local in OS X was no longer needed so it was removed from OS X. It was only used in relation to 32 bit processes.
Have I claimed such a beasts exists ? No. Why should I then be made to provide an example of it ?
Why are you going on and on about something that is not a common threat in the wild?

Who said anything about gender identity?
It lies at the supposed heart of Joseph Nicolosi's and NARTH's work. It's nonsense.
The APA quotation suggests that although there is evidence for that, it's unconvincing.
"There is simply no sufficiently scientifically sound evidence". Anything outside that, obviously barely qualifies as evidence. Not wishing to get bogged down in a tired to and fro about semantics or anything...
That's obviously ad hominem.
So what? That's exactly what he is. He bilks money from deeply conflicted people who feel ashamed of themselves. When the Surgeon General of the United States releases a report saying that "there is no valid scientific evidence that sexual orientation can be changed", then you can be assured that those on the opposite side of the argument have a bill of goods to sell.
Let me ask you an important question. Is there any evidence, testimonial or reasoned argument that would lead you to change your mind?

It's not just "newbies" that have excessive dropped calls on AT&T (and the iPhone in particular). If you really think it is, you haven't been paying attention to this board for the last three years.
I agree. I've been with AT&T since the original iPhone. Reception had been fine up until about a year ago. I, now, have the 3 GS and have had nothing but trouble, with dropped calls and weak inconsistent or non existent signals, for well over the past year or so. I've made multiple calls to AT&T to no avail. Some reps even refuse to acknowledge the problem. The bottom line is that my current contract ends in January 2011. So, I'll more than likely jump the iPhone ship and migrate to the Android then. It's a shame because . . . as David Letterman said . . . you can do everything on an iPhone but make and receive calls :p
Side note:
AT&T's customer service has been so bad I even dropped their home phone service and went to another provider.

While I have misgivings about Nuclear power I do think it is a good midrange solution to our problems until we can solve our battery problems (thus enabling true renewable energy sources to be viable), drilling isn't a viable solution to anything.
The US doesn't have the resources to provide for our society on our own. Not to mention that the whole process of drilling can take decades (meaning 10+ years, not something like 20+) to play through to the point where steady production can begin. You can't just go out and drill, even if you find something you have to set up the supporting infrastructure first before it is viable.
I'm glad you understand the nuclear is a good solution. You're a bit off base regarding drilling though...
First, the 10+ years argument is pointless. Think about it. If after 9/11 we would have started drilling, started seeking out more domestic energy, we'd be producing a ton more of it today (10 years later) and our prices would be less affected by unrest in the middle east today. We'd be more secure today. We'd have a less hawkish view of war in the midwest today. Something good taking a few years to develop is not a reason to not do it.
Second, the U.S. has HUGE untapped deposits of oil, coal, and especially natural gas. And as the facts prove, it's a VERY viable fuel source.
Third, we do in fact have the resources to provide for our own society. Expand nuclear, expand oil, expand coal, expand natural gas, expand biofuels, keep investing in promising new alternatives (private investment, not government) and we could get to energy independence in probably 10 years or less. The only reason we're not doing it is because of burdensome government regulations and the fact that other countries can produce it cheaply. As prices rise, one of those issues becomes moot... Also, for the record, just because we could do it, doesn't necessarily mean we should. The free market should determine this. IF we're willing to pay more for American fuel, then so be it. If not, we'll continue buying from others... but don't let the government manipulate the markets and destroy common sense capitalism.

Somehow this doesn't surprise me at all. However, this is one more reason to stick at 4.1.0.
So far, the only real reason for 4.3.0 is Personal Hotspot, but since that is being monitored, then, I'll be happy to stick in 4.1.0 and give the finger to AT&T.
So if you're sticking at 4.1.0 and they aren't monitoring, then they should be monitoring 3.x even less, no?
All the more reason for me to stick with 3.1.3 on my 3G.

You have every right to rip DRM free music from a CD that you bought, and the same should go for music that you download.
Just because the industry paid the lawmakers enough money to make a law that makes getting around DRM illegal, that doesn't make it wrong!

Of course it did. I think at one point or another all of us experienced some type of emotional pain where our sexuality is concerned. Who wants to be different? Or preached to? Or told by people like you that we may have some type of mental health issue? Or be discriminated against? It's scary and painful.
I can only imagine what the people you know felt conflicted about. I hope that they can find themselves in a place where they will be accepted for what they are, and not what those around them think they should be. Am I wrong to think that if you know these people, their homosexuality wasn't readily accepted by those around them? Of course they would be conflicted. Nobody wants to be hated.[/quote]
I'm sure many rejected my two friends because of their homosexuality. If anyone has deliberately caused them any pain because of their homosexuality, the guilty one should make amends for the harm he did. If anyone attacks my friends verbally when I'm with them, I'll be the first to defend them, too.
MH, please try to give others the benefit of the doubt when they seem to hate you. I can imagine the pain a same-sex-attracted person may feel when a Christians say, "Hate the sin, and love the sinner." Some might think, "Oh no, what will these people do because they 'hate the sin?' Will they keep telling me that I'll go to hell? Maybe they'll beat me up to punish me for my 'sin?'" The pain and the fear must be horrible."
I can hardly tell you how much emotional pain I felt after what some people did to me verbally and physically. I know how it feels when others assume that, since I'm handicapped, I'm mentally retarded, too. I've been in restaurants, where waitresses asked my dinner companion what I wanted because they thought I couldn't order my own food. I even think a male acquaintance of mine sexually abused me when I was a teen.
Emotional pain is nothing new to me. In 1991, when my clinical depression was severest, I almost committed suicide. I don't even pretend to know what emotional agony you feel or felt. But I do know how a felt when I planned to poison myself.
I don't hate you. I'd be honored to be your friend. But if you think I do hate you, I hope you'll change your mind.
I guess with enough "therapy" we would be able to persuade you to become a homosexual?
From what I know about repairative therapy, persuasion doesn't change anyone's sexual orientation.

To all but a few of the replies so far that seem totally out raged by this,
\
First there is no support for itms on linux as it currently stands and this just allows user of linux to purchase songs from the itms and play them on that platform. It also allows someone like me who has a high speed connection at work to purchase music and take it home with me. Yes I have a couple of mac's and an ipod, so my loyalty hasn't changed.
Secoundly this doesn't hack the DRM that apple supplies, however it does violate the EULA, which I don't know anyone that doesn't violate a EULA at least once a day. But that is really a different argument.
Finally why is there no outrage that DRM is not optional or that there hasn't been a standardized format for music. There are reasons why the mini disc failed and it had nothing to do with quality. But it was a propriotary format that needed to be liscencsed. So when looking at the delima of DRM it should be more of a how do we get everything to play everywhere kind of question then just limiting how the user can play/share the music at home. I really hate being limited for "my own good". or more appropriately for the good of a corporation. If WMA beats apple it will only be because they failed to standardize and work within the industry.

Well... it's amazing that now every dual core computer is obsolete, and every single core computer is like an Apple II compared to this.Yes but that 2.7GHz DP G5 of yours is a keeper.

:apple: How would you go about finding out if a phone or carrier service worked in a certain area if you didn't consult other people or credible sources? Wouldn't you have to make a decision based on 'Other Peoples Opinions' in order to find out? If you know Verizon service yields 0 bars in your area do you know this as a previous Verizon service customer, consult someone directly or take the 'Opinion' of the AT&T salesman?
Are you so inflexible as to believe no one in the universe has occasional connection problems? Do you live under an AT&T tower and never stray far from it? I'm looking to get an iPhone in 2 months and I hope it really is as reliable as you describe.
I have set up a contract with a provider BEFORE committing to a long iphone contract. I go into the said telephone store and set up some other non iphone device. Then return home and test its capability and signal strength. If it is acceptable I return the above phone for a full refund(I use it far less than the maximum 30 days. Then when the desired iphone is purchased I will expect the same performance.

While I am not a nuclear engineer, I do have a fair amount of knowledge in the area, so with that in mind I can personally say that this will NOT become another Chernobyl situation. Again though as a disclaimer, this is not my career.
With that said, the BWR should be fine. What we saw earlier was the steam blowing apart the structure-- this just means that they didn't do their job in relieving the pressure. The core should be intact, and the reports state that the housing is still in place. When the control rods are inserted into the core, the rods will not melt down, however heat WILL still be produced. In this case, steam. Steam voids moderate fewer neutrons, causing the power level inside the reactor to lower. Furthermore, there should be safety overpressure valves... not sure why these didn't work; they may not be there due to the age of the plant.
To quote wikipedia about BWR safety:
Because of this effect in BWRs, operating components and safety systems are designed to ensure that no credible scenario can cause a pressure and power increase that exceeds the systems' capability to quickly shutdown the reactor before damage to the fuel or to components containing the reactor coolant can occur. In the limiting case of an ATWS (Anticipated Transient Without Scram) derangement, high neutron power levels (~ 200%) can occur for less than a second, after which actuation of SRVs will cause the pressure to rapidly drop off. Neutronic power will fall to far below nominal power (the range of 30% with the cessation of circulation, and thus, void clearance) even before ARI or SLCS actuation occurs. Thermal power will be barely affected.
In the event of a contingency that disables all of the safety systems, each reactor is surrounded by a containment building consisting of 1.2–2.4 m (4–8 ft) of steel-reinforced, pre-stressed concrete designed to seal off the reactor from the environment.
Again; BWR =/= graphite moderated reactor. Why does no one get this?! Everyone will be fine.
Two more bones of contention (which will give you my perspective):
-I personally believe the linear no threshold model is crap, even with the adjustment factor
-I also personally advocate the use of thorium... there's many benefits, melt-down control being one of them (because of MSR)... also although there's still fabrication issues, thorium can be used in existing LWRs. There is also proposed designs where the thorium has to actively be fed into the core, providing a great shutoff mechanism. The only con to this is the fact that thorium is more radioactive than uranium, so it's potentially more dangerous. I think the pros outweigh the cons.
Do you have a link for this? I'd like to read about it. I would think a system setup to automatically scram when power is lost would be the ideal.
Sure! It's really rather cool. (No pun intended)
For starters here (http://en.wikipedia.org/wiki/Boiling_Water_Reactor_Safety_Systems) is the current safety systems that are supposed to be in all BWR, however since this one is from the 80's, it's really hit or miss-- I can't answer that.
New reactor designs have these systems in place-- for example the Westinghouse AP 1000's. (here (http://www.ap1000.westinghousenuclear.com/ap1000_safety_psrs.html))
A general link about passive safety here (http://en.wikipedia.org/wiki/Passive_nuclear_safety).
Basically though, the idea is that human intervention, mechanical or otherwise, is always the weak point in nuclear safety. Instead of relying upon mechanical or man-controlled means, these safety measures employ the laws of physics and thermodynamics, which I hope are always working :D. Many of these systems rely on heat sensitive plugs connected to tanks to flood the chamber or coolant systems via gravity.
With that said, the BWR should be fine. What we saw earlier was the steam blowing apart the structure-- this just means that they didn't do their job in relieving the pressure. The core should be intact, and the reports state that the housing is still in place. When the control rods are inserted into the core, the rods will not melt down, however heat WILL still be produced. In this case, steam. Steam voids moderate fewer neutrons, causing the power level inside the reactor to lower. Furthermore, there should be safety overpressure valves... not sure why these didn't work; they may not be there due to the age of the plant.
To quote wikipedia about BWR safety:
Because of this effect in BWRs, operating components and safety systems are designed to ensure that no credible scenario can cause a pressure and power increase that exceeds the systems' capability to quickly shutdown the reactor before damage to the fuel or to components containing the reactor coolant can occur. In the limiting case of an ATWS (Anticipated Transient Without Scram) derangement, high neutron power levels (~ 200%) can occur for less than a second, after which actuation of SRVs will cause the pressure to rapidly drop off. Neutronic power will fall to far below nominal power (the range of 30% with the cessation of circulation, and thus, void clearance) even before ARI or SLCS actuation occurs. Thermal power will be barely affected.
In the event of a contingency that disables all of the safety systems, each reactor is surrounded by a containment building consisting of 1.2–2.4 m (4–8 ft) of steel-reinforced, pre-stressed concrete designed to seal off the reactor from the environment.
Again; BWR =/= graphite moderated reactor. Why does no one get this?! Everyone will be fine.
Two more bones of contention (which will give you my perspective):
-I personally believe the linear no threshold model is crap, even with the adjustment factor
-I also personally advocate the use of thorium... there's many benefits, melt-down control being one of them (because of MSR)... also although there's still fabrication issues, thorium can be used in existing LWRs. There is also proposed designs where the thorium has to actively be fed into the core, providing a great shutoff mechanism. The only con to this is the fact that thorium is more radioactive than uranium, so it's potentially more dangerous. I think the pros outweigh the cons.
Do you have a link for this? I'd like to read about it. I would think a system setup to automatically scram when power is lost would be the ideal.
Sure! It's really rather cool. (No pun intended)
For starters here (http://en.wikipedia.org/wiki/Boiling_Water_Reactor_Safety_Systems) is the current safety systems that are supposed to be in all BWR, however since this one is from the 80's, it's really hit or miss-- I can't answer that.
New reactor designs have these systems in place-- for example the Westinghouse AP 1000's. (here (http://www.ap1000.westinghousenuclear.com/ap1000_safety_psrs.html))
A general link about passive safety here (http://en.wikipedia.org/wiki/Passive_nuclear_safety).
Basically though, the idea is that human intervention, mechanical or otherwise, is always the weak point in nuclear safety. Instead of relying upon mechanical or man-controlled means, these safety measures employ the laws of physics and thermodynamics, which I hope are always working :D. Many of these systems rely on heat sensitive plugs connected to tanks to flood the chamber or coolant systems via gravity.

I am religious, however, I have to say there is some sort of motivation inside me to stick to my religion. I can't put my finger on what it is exactly, but there's something there. I'm always looking forward to something for some reason.

The problematic power plants in Japan are of a very old and outdated design. Generation 3, 3+ and Generation 4 design are much much safer. I'm still a firm defender of nuclear power, and I believe with new technologies it is still the future.

No, not really. This would be the only fast update, if it happens (which I kinda doubt)
iMac: 9 months
MBP: 10 months
mac mini: 8 months
macbook: 5 months and counting
Those are actually wait times that are comparable or longer to what we saw in PPC days.
In all fairness, the MacBook Pro received two minor speed updates:
1>> 1.67GHz / 1.83GHz to 1.83GHz / 2.0GHz
2>> 1.83GHz / 2.0GHz to 2.0GHz / 2.16GHz

Flame wars... :D
I know we can't all get along but what's the point of discussing something again and again and... :rolleyes:
Might as well be happy with what you got :apple:

Two weeks ago my service was flaking out. Couldn't make calls or get to 3G all day. Wasn't too happy. Wentthe AT&T store to go vent and the hottest clerk, I have ever seen, was working. She was so hot, she should have been over at VS in VS modellling something for me. wink, wink. nudge, nudge. ;) She said they were working on a go-live of 12 new towers. The engineers had screwed up the configs. So the new towers and some of the old towers weren't playing nice with network. I live in mostly Verizon country. AT&T has been making improvements out the whaz. They finalized the deal for Centennial Wireless. Alot of those towers flipped to ATT recently. So for me, my piece of the network got bigger & better. Now mind you this girl was so good looking she could have told me to set my iPhone on fire and I would have given it serious consideration. It seems like AT&T is trying to act like it cares. So back to mis hottie. I asked for her phone number. ANd she told me, 1-800-331-0500. I think she likes me.
