MacOSX scales very poorly compared to (say) Linux, Irix, or AIX, owing to its Mach underpinnings.
Tiger was the first big step in breaking the monolithic threading model of the BSD layer that was inherited from BSD (not a MACH issue). Leopard is going beyond that in a few key areas, for example to allow better efficiency on high-core count per socket systems.
XNU handles multiple cores just fine but improvements can always be made and they are being made.
8 cpus won't get you much over 4 until Apple rips out the Mach guts and replaces it.
That is simply false. The schedular in Mac OS X handles 8 cores just fine... what Applications do with them in a different story.

Hopefully someone at ATT will read these posts! In the same boat, last 3-4 weeks been getting worse in R.I.
It won't matter. I am a firm believer than unless you have pressure from a competitor you can take your time fixing your problems. And until the iphone ends up on another carrier I can't see AT&T; making improvements for Iphone users a priority. Despite what steve says I believe that the AT&T; networks would be better if the iphone was on multiple carriers. It may have been a good decision for steve financially to make it exclusive but its not a good decision by steve for the iphone users.

^^ It's hard not to veer from apocalypse to there's no problem,but I think a pragmatic view would be that there are serious problems (injecting seawater is a novel and DIY approach) but a meltdown is probably not on the cards,nevertheless they've got major problems,at least some core damage has happened but the reactors are shut down they've just got to get rid of the heat,so far so good.

What I really would like to know is when the eight-core Mac will be available.
Does anyone remember how much lag there was between the availability of the Woodcrest chips and the time the Mac Pros came out?
The new Quad core chips are expected to be out in mid-November. Considering that the new chips work with the current Mac Pros, so long as Apple doesn't plan on having big changes to the motherboard, they could theoretically update the product line pretty quickly.
I've asked someone who needs to purchase large quantities of professional machines from Apple for a company, and he couldn't get info from tight-lipped Apple about this.
So I just wanted to hear some educated guesses to help with my impatience. :)

I did a little reading and now am a one minute expert... :p
I've read these reactors did auto shut down when the earthquake hit. The problem is that the rods create tremendous persistent heat even after a shutdown, and it is the lack of cooling water that is causing the problem.
Could it be considered a myth that any nuclear reactor can be expected to automatically safely shutdown when power to all safety systems are lost no matter how it is designed?
And who was saying this could not be like Chernobyl??
If you want to get technical, the lack of cooling water was caused by the inability to activate the backup generators. The switchgear for the backup generators was flooded by the tsunami. I could come up with a ton of engineering design decisions that could've prevented this and none of them have to do with the reactor or nuclear technology
- Not putting critical switchgear in a basement that could get flooded
- Pre-installing pumps in the basement to remove the water in the case of a flood
- Having a redundant set of switchgear/BU generators with an additional switchover scheme in the event the primary switchgear malfunctions
- Having an additional distribution panel or tap point so I could use portable generators to power the cooling system
- Building a taller tsunami barrier
- Putting all critical components in a secure building, not just the reactor.
Even though the radiation leak is devastating because, well it's radiation, it's the electrical and structural engineers who failed here, not the nuclear engineers. Personally I think there needs be a design standards revision when it comes to nuclear stations, which is what I'm hoping other countries are referring to when they say they're watching and taking notes.

I think this whole issue with Apple, DRM, & the music industry once again makes it perfectly clear that this distribution model is flawed. I have never used the Apple Store because I won't support digital encryption methods that restrict rights for the sole purpose of profit. I buy cd's and rip my music.
The recording industry needs to change or die. We are no longer living in the 1950's. Making perfect copies of recordings and distributing multiple copies of the recording is no longer the significant monetary burden it once was.
The recording industry needs to shift to a new business paradigm. If downloading music is to be the standard for distibution then profit-margins should be reduced to pennies per song. Artists should try to generate income through live-performances, or through managing their own web distribution system, charging a few cents a song.
The recording industry wants to be compensated at ever increasing rates even though technology has significantly reduced the cost of doing business. They can't have their cake, eat-it too, and lose weight.

No, I believe Apple will pop the Core 2 Duo Merom into the iMac. It's supposedly a drop-in replacement for the current Core Duo processor the iMac currently uses.
This will not be an option for Apple. They no longer live in the PPC world, now people can directly compare the specs on any Mac to the specs DELL or other PC vendors are offering.
The iMac is Apple's desktop computer, and currently the only one they offer. As such they will have to spec it as a desktop computer as much as humanly possible, and having a slower CORE 2 Duo than their competitors (when iMacs cost more) will not do them any favours.
Also bear in mind that Conroes are cheaper for apple to buy than Meroms, as well as offering faster clock speeds and more performance. So it wouldn't cost Apple much more, per machine, to put a 2.4Ghz conroe in rather than a 2.0Ghz merom.
The heat issue is also a non-starter. I have a laptop with a 3.2Ghz Pentium 4 in it, which runs a hell of a lot hotter than the Conroes will. Sure it isn't the smallest laptop ever, but it's comparable in size to an iMac, if anything it's slightly thinner. Many laptop venders have said they're putting conroes in their top laptops because of the extra performance, and if they can there's no reason Apple can't fit one into the iMac.
Apple can either put Meroms in the iMac and thus make an over-priced under-performing desktop or redesign the motherboard for Conroe and have a competitive desktop. If they want to continue their recent success with the switch to Intel they cannot afford to be lazy and simply drop a merom into the iMac.
Personally I'm also hoping for the option of a BTO X1800 graphics card. At the least I expect the VRAM on the X1600 to be bumped to 256Mb on all iMacs and for the screens to get a resolution bump. The 17" will get the same screen as the 17' Macbook Pro (1650x1050) and the 20" will get a resolution bump to something closer to True HD (like the cinema displays) which is what professionals will want to work with.
First post, woo!
EDIT: My dream iMac config would be:
17" 1650x1050
2.4Ghz conroe
2Gb RAM (BTO)
750Gb HDD (BTO)
x1800 512Mb (BTO)
And I would be willing to pay quite a bit for it. Fingers crossed apple offers it...

Pretty much like a weather vein or TV aerial. Provides a couple of hundred watts at 24V or 12V. I was thinking about one for if there is ever a blackout (ie a drunk hitting a power pole, it's happened) instead of needing a petrol generator.
Every home generating 500W of their own wind power with one of these little things on their roof in a city of Los Angeles with a million homes = 500,000,000 watts. As well as a solar panel at 500W too is up to a billion watts not required from any central power source.
California is making great strides in this area. Through creative financing, tax breaks, and fairly high electric rates, quite a few people have solar. It's especially important here in the summer when electricity use is at its greatest.
However, the one thing that nobody has brought up is that evil word..... CONSERVATION
Not using electricity is a lot cheaper all around than building a new power plant, no matter the fuel source.

Still, people love the Tivo interface, so to get them, it's gonna have to offer MORE than Tivo- like an optical drive, a couple tuners. No WAY that is in this box and "not discolsed yet" at 299.

Is the battery life as bad as I've heard? I think I prefer the Incredible to the Droid X (mainly because of size), but I hate not being able to make it through the day without charging my phone.
It is going to be a real subjective answer because it all depends on how much you use the web/apps/games. To make it short, I don't have an answer for you but it does have a much better battery life than my 3G.

The problem is, and maybe I misread, that it only counts as "rape" if the woman fights back. All rapes are different, just as all women are, a rape victim I know personally, went into a catatonic state during the sexual assault. So, by that definition, she was "consenting" and should be stoned as well. In some cases, the assailant will threaten death of the victim/victim's family to ensure submission. So do these count as rape, since they're not fighting back?
I wanted to make it clear that a person would need to be in a state of awareness that allowed them to resist. This may not always be the case. Like your example, some people may not be in a state that they are able to resist. The point of those examples in the bible were not to define rape or the final verdicts for cases of rape. They weren't written to judge whether a person was truly raped or not. Every situation is different, and it's in no way implying that a person hasn't been raped because they didn't demonstrate that they were resisting.
The point of my original response to another commenter was to clarify that the bible doesn't simply instruct people to stone a women to death because she was raped.

I know where you're coming from, but surely it's a good thing to try and get the companies we use to improve their environmental policy? If Dell does recycle more than Apple, then maybe Apple should recycle more. If Apple's stuff lasts longer, Dell should make their stuff last longer. And yes, at the same time, we should be putting pressure on companies to reduce food packaging and use less power and fuel. I don't really see it as a competition between companies, more that if one company does something environmentally better than another, the other should try and match it, you know?
My point is that Greenpeace would be far better served educating the public how to help. They get even 10% of the world's population to make some radical changes in their lives and the changes to the planet would be amazing.
I agree corporations need to set examples and do teh best they can. I don't think its where environmentalists should be pointing fingers.
You , me and everyone else are the biggest polluters.
I'm as guilty as teh next guy. Nothing stopping me from peddling a mile up the street to Trader Joe's tonight for my dinner. Except laziness. :D

Malware like this has been around for quite some time. It's always been the same - just exit the stupid installer and absolutely nothing happens.
Now if/when the malware auto-installs, by THEN it will be a threat. So far Apple has been good at patching loopholes, though.

How much power does it take to provide and maintain storage of the waste, and to mine the uranium? What impact does the operation of the plant have on the environment? What is the cost to humans and the environment when these plants fail as they have?I have been arguing that the ramifications of catastrophic failure of these plants, quite apart from any energy and pollution costs in building, keeping them running and decommissioning them, those ramifications alone serve to put nuclear power on a wholly different level. The equation has to be considered in its entirety. Taking the other costs into account makes it quite obvious that its just not worth it.

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?

What!! HAHA, do you know your TV is downrezzing to 720? So, how does 1080i look better than 720? You can see the difference between downrezzed to 720p-1080i and 720p, but you can't see a difference between HD and a 480p DVD?!!
Either you need a new HD set, or a new HD provider. There is simply no comparison, really. HD is night and day, leaps and bounds better than DVD.
Apple's iTV would NEVER do HD, it simply is a chain between your HD tv and your mac that DOES do HD. Your computer is the player, so yes, I'd suspect I could record HD off my g5, and stream it to my HD set.
Can't wait!!!
My TV is actually 1080i native... upconverting 720p, not the other way around...
