2) A CT scan is 150 mrem. Depending on the X-ray, it can be around 30-50 mrem.
I have no idea why these sorts of examples are constantly used to allay peoples' concerns. Do you actually believe people actually think getting an xray is as harmless as washing with soap? We all see the technician/dentist/nurse go stand behind the protective screens when they use these things while telling us "it's fine, won't hurt you" and we all think "horse manure it won't" as the machine goes click click..
You should do some reading; that dosage of 52 mrem/hour isn't going to stay like that for long.
My reading of the NYT article says they could be releasing clouds for MONTHS if/until it's under control, so why do you assume it will not stay like that for long? Speaking of under control..
The residents will be fine, you can put away your tin foil hats. If we have a melt down, then we'll talk.
See, you're downplaying it again. I don't know why, perhaps it's just your nature to adopt the calming 'please remain seated' role when the theatre's on fire. Just don't mock the headwear of the people who advise to run for the exits instead while you do. Each to their own.
What do you mean *if* we have a meltdown. Are you denying there has been a meltdown at all? I'll wager with you that there is not only just a meltdown, but actually *three* active meltdowns currently in progress right now. Even so, I'm not even sure where your confidence over the 'if' comes from, everything so far that we're seeing indicates that they are struggling to even keep the situation under control let alone stabilize it, so I believe it's more of a certainty than an if. I believe they are failing, if not already failed, and the situation is already out of their control so it's only a matter of time.
Edit - my beilief is based on reading stuff like this (from the BBC) about the hitherto quiet reactor #2. While all the focus has been on the exploding #1 and #3, they've also been pumping seawater into #2 as well. So not only is that yet another wtf? moment, we also have a wtf? squared that the fire engine truck ran out of petrol to keep the pump going so the rods were exposed. So I hope you can understand what I mean about not having confidence that they are even abe to stay on top of the situation let alone control it.
According to the main Japanese news agency Kyodo, the rods were exposed when the flow of seawater into reactor number 2 stopped simply because a fire pump ran out of fuel.
With the entire region of Honshu island reportedly low on fuel and other vital supplies, a key question is whether plans are in place to keep the power station supplied with diesel.
Edit 2 - the irony of a nuclear power station needing fossil fuel to save it...

That's fine. As long as Apple does not come in to the gaming market and starts trying to strong arm third party big names all is good.
lol you are saying it like they can be strong armed. If you call paying large sums of money for exclusives "strong arming" then it's already happening in the gaming world.
It is really simple big names go to where the money is.
Apple has their rules. If you believe you can't work with them go somewhere else. It's a business, not a country you are born into.

I think this is a great product from Apple and shows great foresight. SJ and Apple recognise that they can't surplant the TV from the living room.
And for everyone already moaning over a 'beta', I dont even know what to say to you. There is a reason it is not being released today. Is it perfect yet? No. Is it complete? No. Will it be able to record TV shows? Who knows? But its good to bear in mind that this is not a final product, and seems to me like its FAR from being done.
Overall, good job by Apple. It's definitely a move in the right direction.

IMO, not much. A couple things would be the ability to do all of those a bit faster, but that only makes a difference if you're being held back by your Mac at the moment.
2 points: 1) I think the computing industry has historically been all about the trickle-down effect, where the highest of high tech starts at the very top - the high-end workstations, the mainframes, etc. - and trickles down into low-end workstations/servers, then desktops, then consumer electronics. This could be seen as a technological entropy of sorts, and if you look at it as a hierarchy, the PC (hardware wise) is closer to the root (top level) of that hierarchy at the moment. What that means is that it's closer to being the latest & greatest than the Mac is, which puts it in a position whereby its relative speed advantages are self-perpetuating, in that being closer to the source of the newest, best technology, it has a chance to incorporate that technology before the Mac does, thus raising itself up on the hierarchy yet further. This explains why PCs have been eating into the specialty markets of SGI and Sun (and Apple) and show no signs of stopping. The Mac is a fantastic platform, but it has some formidable competition that is driven by the pure force of the capitalist marketplace, and when you look at it that way, you realize how amazing it is that it has held on all this time.
2) Software is always getting more featureful and less efficient. (With a few exceptions, like the way the performance of OS X has improved between the public beta and Jaguar.) The kind of Mac that's adequate now (say an 800MHz TiBook) will probably seem quite slow in three years, whereas if you buy a top-of-the-line PC notebook today, it could easily last 5 or more. With OS X, the days of Macs lasting 5+ years are gone, at least for the moment. We do things with our computers today that we didn't do with them 5 years ago - mainly due to the trickle-down effect. We do pro-quality video editing on consumer-class machines, our resolutions and color depths are higher, our digital cameras take higher-resolution photos, our audio & video is encoded with more processor-intensive compression codecs, and hell, our email client has a little tray that slides out! (Imagine animation like that on a ca. 1997 computer running a ca. 1997 OS!) A Mac will always be able to check e-mail, but so will a Performa or a 486. But I don't know how many people Performas and 486s appeal to. Probably not many... you tell me why. :)

That's the Kentsfield chip not the Clovertown (Xeon) CPU but the benchmarks are interesting.
Just as expected the Quad cores are only going to be a big improvement for the software that can utilize them. Software will catch up with multicores, hopefully by Q2 07 when I'll be buying a new machine.

Bigger, most Windows PC have anti-virus, can you say the same for Macs?
Except antivirus doesn't usually catch things like this, neither does anti-spyware since it acts like a legit program.
I fix windows machines and servers for a living an unfortunately a majority of my week is spent removing said malware from windows machines.

Reading the comments about $299 being a pretty good deal truly makes me laugh. Ten years ago a system of such capacity would be > $50K and you're downplaying $299.
Grow some perspective.
This is the problem with low-low pricing. If Apple charged $40k, maybe all the "professionals" would be onboard!
I think it is great to see the simplification of the product line. FCE always seemed an odd product out.
This is the internet. People are more invested in their egos than in understanding each other, and since several people have chosen to put words in my mouth to attack me, there's no point in really trying to advocate for the product here. Let the haters have the thread, I'm out.

Stuck record! Same old comment, still not true.
They can sell as many as they can make, production is the limiting factor at the moment NOT lack of demand.

I think part of the problem may have to do with the fact that the plants are designed by engineers. Engineers' focus is elegance: accomplishing the most in the most minimalist way. Nuclear power plants need much less minimalism and elegance than just about anything else humans can make, but costs and other limitations tend to guide the design toward what engineers are best at. Redundancy and over-building are desirable, I believe we end up with too much elegance instead.
I was paraphrasing something a nuclear physicist once told me. I didn't get the sense that he thought it mattered what type of human was involved.

The problem with your attempts to downplay this situation, like all the other attempts in this thread so far, is that every time you get hammered by actual events on the ground. To wit:
So rather than fear-mongering appearing to be unwarranted, it's actually the other way around. The fear-mongers have yet to be proved wrong while the down-players' positive predictions have been proved wrong every step of the way. It's almost like the down-players are having as much difficulty staying on top of this situation as the plant owners/workers themselves. Here's a hint - it's out of control and has been all along. Everything we've been seeing the last three days is simply trying to regain control, not actually control it. To wit:
All workers not drectly involved in the actual pumping have now been evacuated from Fukushima nuclear plant. They're running. So everybody else should too.
EDIT - I just re-read that BBC quote and realized it's even more staggeringly worse than when I first read it as '8 times the legal limit' - where in fact it's 8 TIMES the YEARLY legal limit in just 1 HOUR.
Here is the article to which you referred. http://www.bbc.co.uk/news/world-12740843
It fails to mention that the statistic noted, "8,217 microsieverts an hour" was measured at the front door of the damaged power plant. Link (http://www.naeil.com/news/eboard_view.asp?location=1&mn_id=3149) As was said in the article I quoted above, radiation levels decrease drastically with distance.
Someone has a Geiger Counter reading set up in Tokyo (I assume that is the location). If someone can explain this that would be wonderful.
LINK (http://park18.wakwak.com/~weather/geiger_index.html)
[/URL]
Based on every online source I could obtain, readings of <100 CPM are significantly LOWER than readings you'd get if you took a geiger counter on an airplane. [URL="http://www.blackcatsystems.com/GM/geiger_counter.html"]Link (http://park18.wakwak.com/~weather/uploaddata/radiation.jpg)
...And given the highly unknown nature of that graph (how sensitive/reliable the equipment is, who operates it, where it is, who compiled the information, etc.) it's a dubious source at best. Though there isn't anything suspicious about the data, I might add.

Cutting a deal with a hacker, if we can get one who's up high enough ...
This sounds like you're under the mistaken impression that hackers are members of some kind of organization or ranking.... they're not. They are, for the most part, quite independent. There's no such thing as "Hacker, Class 3" or "Hacker, Class 1". Also, not all hackers write malware and not all malware writers are hackers. The more you offer such statements, the more you reveal that you have no idea what you're talking about.

I politely disagree with the idea that lots of apps are necessary to make a smartphone popular. For one thing, I suspect there's not really more than a few thousand unique apps. Everything else is a variation and/or a lesser version of a good one.
Look at RIM. Only about 16,000 apps but they outsell many other phone types.
Look at the iPhone. Over 2,000 tip calculators alone! Nobody needs that many choices.
Windows Mobile has something like 30,000 apps. But out of a half dozen versions of each app, there will always be perhaps just two or three that are recommended between users most often: usually a free one, a paid inexpensive version, and a paid deluxe version.
As long as the major apps are available in a decent version, a phone will sell.
Again, the iPhone is an example. When it first came out, it was arguably just a feature phone with no apps. It had what other phones already had... Google maps, a browser, media player and some widgets. But it had nice ones which were easy to find and use... and that was enough to make it sell.
For that matter, the iPhone sold even without some of what I would consider major apps: VoIP and Slingplayer over 3G, MMS, Pandora in the background, decent home screen, and games.
I would say that the user experience and how it fits with that person's lifestyle, is far more important than apps.
Regards.

You know its not just apple, its intel and many other companies. You see it is not profitable to make something last nowadays. Remember when TV's could be repaired? Not anymore.
Ever wonder why every time a new mac comes out or any computer comes out you need to buy all new ram? Its not really that much faster. How about the CPU's? When a new one comes out why can't I just put it into my old computer and go. Socket this and socket that, they are all just sockets. Why does the Xeon need a different socket than the Core 2 DUO? Same CPU basically. Although with core intel has kept the same sockets as Pentium Ds but you need a new chipset.
We as a society could reduce the amount of computer waste by half immediately if a standard was devised to allow upgrades to work without purchasing all new computers. Heck, apple could just sell motherboard upgrades for its entire line of old computers and that would be great. No company will ever really do what it takes to save the environment because that costs them $$ in the end.
Humans are a cancer on the planet. Look at pics of the earth from space. Its disgusting.
Earth is going to look like Cybertron (Transformers home planet) folks. Just give it time.

Nuclear is the only non-fossil fuel which has proven itself capable of producing sizable amounts of electricity. Wind, solar, etc. are a complete joke as of today. Instead of the OP, I guess the question you really need to answer is, should we make decisions based on sound reality based scientific data, or short-term, panic-mode, irrational reactions to the effects of an extremely rare national emergency which could have been better prepared for (like not putting the plant on the ****** BEACH!)
For those of you advocating the elimination or reduction of nuke power, just realize that the only feasible alternative currently is...
Drill baby, drill!

This is an excellent initiative. Bullying goes on beyond high school and college too. You see it everywhere. There are parts of our cities where it's just unsafe for any of them to go walking alone, just because of how their sexuality is perceived by the ignorant and thuggish class. I think that's sad - clearly there's still a long road ahead.
Good on Apple employees - and all others who partnered in this initiative - for speaking up.
Maybe the next generation will be the one that shrugs its shoulders when discussion of sexual orientation comes up, like it's no big deal, because no one really sees it as a major social issue anymore. Maybe then the bullying will stop, having lost a target.

Isn't this misleading? It says 'shipped' not 'sold' so I assume basically it's a bogus report. You can ship all the crappy tablets you want..doesn't mean they sold.
I'm trying to find more on it but as far as i've read somewhere apple's data is always on units shipped including those that were used as warranty replacements (pretty much they count one as two in this case) for example. Waaay stretched in my opinion.

Software might not need that powerful of a processor, but what about OS? Heck Itunes shutters on my bros 2008 Macbook Pro, which is basic software.
Huh? A 2008 MBP should have no problem running iTunes.
Flash can barely run on his computer also.
Flash for Mac sucks even on the most high-end Macs. Why do you think Mac users tend to dislike Flash? It's not the Mac - it's Adobe.

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.
