Presumably this is/was the selfsame containment building which was supposed to contain the pressurised radioactive steam which was vented from the reactor. The billowing cloud is described elsewhere as "vapour", i.e. "steam". Seems difficult to reconcile the picture with public statements about a "tiny" amount of radioactive material being released.

It will come, just not with the initial production models. With the quad-core chips, Intel is already running into FSB bandwidth issues as it is. The Clovertowns are essentially dual Woodcrest CPUs stuck on the same die, sharing the same FSB and communication between the first duo-core CPU and the second duo-core CPU on that die must travel onto the FSB and into the other CPU. Between the two cores that are linked directly, data sharing can be handled through the L1 cache. So, depending on your application, the 8-core may be no better than a 4-core system -- if what your'e doing is already maxing out your CPU bus bandwidth. Somwhere down the road as Intel shifts to its 45nm production process and fully integrates all 4 cores on a single CPU (and later, 8 cores on die), we will see massive improvements in inter-core bandwidth. They will have to step-up on the FSB bandwidth though... Possibly by increasing the MHz, but more than likely we'll see some of that combined with increasing the width of the data path and possibly using multiple parallel FSB designs. ...Going to be interesting, that's for sure. And with Intel's new process and the plans for continuously jamming more cores onto a die at higher speeds, I think we're in for a real ride over the next 5 years or so.
Absolutely agree. It must be exciting to be an EE working on this stuff right now. So many options to explore. How would you design a memory bus which would be dynamic enough to adjust for a doubling of processors? If you had a fixed, known number of processors, the design is straight-forward. But, the new multi-core design is not something they have had to deal with before. I wonder how they will do it?

I can honestly and without exaggeration say that over half of the calls placed with my iPhone drop, and it's been getting progressively worse in both cities where I use my phone. It's practically unusable.
My phone so consistently cycles between full bars and no service that Apple replaced my phone under warranty, to no avail.
I love my iPhone, but AT&T needs to go.

So exactly what "pro" features were removed with this release?
The dull gray colour, the fact that it isn't an elite app costing over $1000 making it unavailable to the mass.. uhmm the huge instruction manual?

It'd be great if we could get an engineer-type on here that actually knows how all this stuff's supposed to work. Not a flack from AT&T, or another pissed-off complaining customer, but someone who can say "It isn't working properly because. . ." in a fashion we can all understand. Just saying.

The reason Apple "performs poorly" on recycling compared to Dell is that Apple computers, on average, remain in use approximately twice as long as Dell computers. Instead of being recycled, they are still being used. Apple does, after all, have a free recycling program. And there is no way that making computers that are replaced more frequently is more environmentally friendly.
It also seems that most of Greenpeace's complaints focus around Apple's refusal to provide Greenpeace with information on what materials are used in manufacturing its products.
Greenpeace does not have an exactly spotless record when it comes to ethics. Makes you wonder if it gets its computers from Dell at a discount.

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.

Actually the reason why it isn't encoded with DRM on the server is that if they did that they would need a copy of every song for every customer they have on the server.
aah yes of course.. (slap on forehead). hmm.. then adding DRM on fly before delivering might be the workaround apple does... although as noted in my previous post, that can be defeated too.

I'm inarticulate. Well, if it is extending benefits heterosexual marriages then examine why it is doing so and then see what the differences between a heterosexual marriage and a homosexual marriage would be.
The reason you are telling me to do that is because you cannot. Neither can the government. That's why it is wrong.
Nearly forty years ago psychologists declared homosexuality was not a mental illness. Nearly ten years ago the Supreme Court ruled that the government has no authority to criminalize consensual sexual acts between any two people, regardless of gender, in the privacy of their own homes. The state of the art in science and law once provided justification for the discrimination you want. Neither does any longer. It is no longer understood to be the case that homosexuality entails a necessary harm to the participants or anyone else. Quite the contrary, same-sex couples are known to form loving, supportive, monogamous relationships every bit as profound as those enjoyed between men and women.
This being so, the government has an obligation to prove that this distinction has not outlived its legal relevance. Hint: it has.

Simple swap has already been tested and confirmed to work in early September by Anandtech (http://www.anandtech.com/mac/showdoc.aspx?i=2832&p=6).Not really. The 2.66GHz Clovertown lists @ $1172 vs. $851 for both the 2.33GHz Clovertown and the 3GHz Woodie. Since Apple charges +$800 for a 3GHz Dual Woodie, this means they will likely charge only +$1100 for the 2.66GHz Dual Clovertown - total $3599. Hardly expensive at all. I'd say they are going to be a bargain and LESS EXPENSIVE when you look at the per core price of $450 - or PLUS $275 for each of four more cores.2.66GHz is not significantly slower than 3GHz - especially when the workload can be shared among many more.
There is one error in your calculation: The 2.33 GHz Clovertown and 3.00 GHz Woodcrest cost the same, so you would expect the same price for both systems (price of 2.66GHz Woodcrest + $800, like today). However, the price difference between 2.66GHz Clovertown and 2.33GHz Clovertown is $1172 - $851 = $321 _per chip_ which makes it $642 _per eight core system_.

If you are going to buy something to mainly play games on when you are out of the house which one are you going to buy.
Ipod Touch: 230$ USD
Nintendo DS: 130$ USD
PSP: 130$ USD
I think the price of the PSP and DS make them more attractive that and the point they are not an mp3 player that can play touch games.
The iOS devices do not have the hardware that a made for gaming handheld has. a PSP still has better graphics then any iOS game rendered on the spot. The PSP and DS also have a larger advantage...Hard buttons. for real gaming that is a must.
I think the problem Nintendo and Sony will have with iOS/Android devices isn't people picking one or the other. It's the fact that the iOS/Android devices are getting so ubiquitous, they have to compete more with, "Do I get the PSP/DS on top of this phone I already have that I can get games cheaper on? Sure, they are better suited, but 1. I already have this device 2. games are cheaper 3. This device is more portable and can go with me more places 4. I wouldn't have to carry around two devices if I wanted to game somewhere."
Basically, Nintendo and Sony have to have advantages that make up for the advantages some one would see in just using the smart phone they already have. And part of the problem is that you are starting to see some of the same games on the smart phone. Or at least similar enough games that you may not need to get that DS or PSP if you want to play something similar. Sure, there are compromises, but for some people (like me), the compromises are worth it and it's not worthy buying a whole 'nother device.
Sure, you'll get some hard core gamers that don't want to compromise, but the question is, are they enough of a market to keep the non smartphone handhelds afloat? I think for the sake of us who do want to compromise, we should probably hope, cause for new games that is where the money is (notice most of the games that are not "angry birds" or freemium gams on the iOS are ports over from the handhelds. Though iOS is starting to see some original games made just for it too, Chaos Rings or Eternal Legacy anyone?).
So, the threat isn't choosing between the two devices, the threat is that smart phones are becoming so common, they have to convince people that it is worth buying their handheld device *as well* as the smartphone the person already has.
I will agree that consoles have nothing to worry about (but they didn't have anything to worry about from any handheld, they are not really competing in the same market at all).

According to Corante.com (http://www.corante.com/copyfight/archives/2005/03/17/johansen_creates_drmfree_interface_to_itunes.php), from the same authors of QTFairUse (http://www.macrumors.com/pages/2003/11/20031122001549.shtml), comes what is described as "the fair interface to the iTunes Music Store". The application called PyMusique (http://fuware.nanocrew.net/pymusique/) acts as a front end for the iTunes Music Store and allows users to preview iTunes songs, signup for an account, buy songs and redownload songs that were bought with PyMusique.
The most notable twist is this quote from Jon Johansen ("DVD Jon"), one of the authors of the application:
It is somewhat interesting from a DMCA/EUCD perspective. The iTunes Music Store actually sells songs without DRM. While iTunes adds DRM to your purchases, PyMusique does not.
Note: This application has been untested by this site, and Apple will likely take steps to prevent future usage.

So, first it was the number of transistors per processor, then they coupled that with higher clock speeds (MHz) and now with multi-cores inside multi-processors.
Is there a limit to such growth with the current technology?
Anything after that? The optical computer that works with light instead of electricity and thus does not heat soo much? Any roadmap?
Thanks.
How about Quantum computers?

I don't think that the cost of buying a mac is the problem, it's the availability of the initial experience with the SDK. 125,000 developers already signed up - I think that there would be at least twice that if the SDK could be used from Windows.
I agree, I did not run out buying a mac when I found out I wanted to try to make a mobile game. I did it on the Android sdk, halfway through Google had still not sorted out publishing paid apps from my country so I bought a macbook, an iPhone 3G (which I love) ported the game and published on the app store. Today I am thankful that google delayed. Android and Java is a dog compared to the iphone. Help people see the light! :D

It's easier to admit being an atheist on the Internet than in the real world, as even the Dalai Lama seems to hate atheists. Although only a fool would say in his heart "there is no god", it should be legitimate to say "I want to see proof before I believe".
Oh - and about the universe not likely being made by chance: a designer must be more advanced than what he creates, and where does the designer come from? I'm not saying that there is no such designer, just that I don't see any reason to think about that in the first place. Wouldn't it be far more likely that the universe is made by itself rather than by some creating force being made by itself?
I depends on where you are at and what company you are in. Your "immediate culture" plays a large factor in how you are "accepted into society". It's no different from nerds vs jocks in adolescence. People are people. For example,
It's hard to "admit being an atheist" in the rural areas.
It's easier to admit it being an atheist in the big cities.
It's hard to admit being an atheist among working class folk.
It's easy to admit being an atheist among college students and higher class folk.
It's hard to admit being atheist among white and latino ppl.
It's easy to admit being atheist among Asian ppl.
When you're always surrounded by ppl of a particular culture that is majority religious, you will think that "atheists" are closet freaks. Just like how "gays" are stereotyped to be. But that's not true everywhere. And there are many ppl who say "there is no god", but personally I find that it's usually younger ppl. A lot of ppl with higher education also would say this, but they are very careful, because when you are "mature", you are also wary about respecting other ppl's beliefs around you so they are careful not to say it to a religious person. Because it might insult them...as many religous ppl are also implicitly taught to HATE others who are not like them.

Japans main problem, at this time, seems to be that someone thought it was a good idea to build the plants on the Pacific Rim (Yes, I am well aware that the West Coast of the United States lies on the Pacific Rim). A majority of the problems Japan faces currently appear to stem from the earthquake and the fact that the plants were dated and not built to withstand the magnitude of the quake (they were built to within a 7.5 quake, no?).
From what I heard, it wasn't the quake that was the problem, it was the Tsunami that destroyed the backup generators that were supposed to maintain the cooling system. After that the cooling system defaulted to battery power, which drained within 8 hours. After that the overheating started.
I think if the engineers who designed the plant paid as much attention to protecting the backup generators as they did to protecting the reactors, there'd be no issues right now.

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.But diesel has significantly more particulate matter in it - bad for respiratory health - particularly in cities.
- 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.How much gas does it take to manufacture 1 gallon of gas? What if the E85 started being manufactured without using energy from oil?
- Ditto the above for hydrogen-based fuels.In the future, H-based fuels can be manufactured with renewable energy sources. Gas/oil is never going to be a sustainable route because the raw products are finite.
- They've indirectly caused the deaths of thousands of starving Africans by preventing the development of genetically-engineered foods.Out-right banning GM is a mistake. But putting the control of GM foods into the hands of powerful multinationals - and not in the hands of the people of Africa - would be a bigger mistake.
So who is Greenpeace accountable to? You and I. Just like everybody is.

- 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.How much gas does it take to manufacture 1 gallon of gas? What if the E85 started being manufactured without using energy from oil?
- Ditto the above for hydrogen-based fuels.In the future, H-based fuels can be manufactured with renewable energy sources. Gas/oil is never going to be a sustainable route because the raw products are finite.
- They've indirectly caused the deaths of thousands of starving Africans by preventing the development of genetically-engineered foods.Out-right banning GM is a mistake. But putting the control of GM foods into the hands of powerful multinationals - and not in the hands of the people of Africa - would be a bigger mistake.

Stompy, a few posts back somebody mentioned that the OP was later banned. That might explain why he hasn't come back.
The OP was not banned. Just check the 1st post of this thread to see the OP is still around.

The iPod wasn't an instant success, sales only really only took off after the introduction of the Dock Connecter, but mostly the Click Wheel. This places it in with big sales really starting in 2005. That timeframe to 2009 (which was peak iPod sales, and included the Touch) is only 4 - 5 years, not a decade.
I think the real reason the iPod took off around that time was because it was properly opened up to the Windows market with the introduction of USB syncing and iTunes for Windows.
