As someone already mentioned, mining uranium isn't "green". Dealing with radioactive waste isn't "green". Releasing heated water back into the environment isn't "green".
Fission itself may not produce greenhouse gases, but calling nuclear power "green" seems like quite a stretch.
(I have to correct my quote (http://www.ecolo.org/media/articles/articles.in.english/love-indep-24-05-04.htm)... he described Nuclear as the only Green solution, not the only green choice - but the meaning is equivalent)
To answer you citizenzen:
1/ Perhaps you should take your complaint up with James Lovelock. I'm quoting him - I don't recall calling Nuclear energy 'Green'.
2/ Your English comprehension could be better. Calling Nuclear 'The only Green Solution' (or Choice) is NOT calling it Green. The opinion piece merely points out that hydrocarbon burning is LESS Green. See the difference?

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.

I know, right?
God forbid someone have an opinion that differs from yours.
It doesn't matter how that differing opinion is presented, if it differs you don't like it.
Typical fanboys.
I tried to be respectful by stressing the fact that an Android phone works best FOR ME, and by also giving credit where it's due because the iPhone is a beautiful piece of machinery.
But to no avail.
I don't mind that you have a different opinion, you just represent that opinion badly.

From Cult of Mac's blog (http://blog.wired.com/cultofmac/) on the issue:
I have now had the chance to read through Greenpeace's "Guide to Greener Electronics," and there are a few things that should be clarified about where Apple ranks.
First of all, the article I linked this morning claimed that Apple and Lenovo were at the bottom of the charts. Well, that's not true. Lenovo scored an appalling 1.3 out of 10 while Apple pulled a marginally more successful 2.7 out of 10. In between were Motorola and Acer.
The criticisms of Apple are fair, I would say, though I think there's some nuance to what HP is doing with recycling that tends to make it look unfavorably better than others. Why? Ink cartridges and printers. HP has a lot more to take back than any other company, so their commitment to percentage of sales taken back is actually a possibility.
Given that Apple actually offers free computer recycling with the purchase of a computer, something that Dell does but HP does not, it's odd to say they're doing less to keep computers out of the waste stream. On the other hand, Apple has no takeback goals, so it really does balance out.
The other criticisms of Apple are on target, however. The company is secretive, and that meets they tend to be secretive about their environmental planning as well. They have a regulated substances list, but it isn't public. They're committed to eliminating PVCs, but won't say when. Ditto for BFRs.
It's not necessarily that Apple's environmental record is legitimately bad, but they do a very poor job of informing their customers about their environmental efforts. Silence is suspicious here, folks.

I have a huge drop call and coverage issue at my new home in Rancho Cordova, CA. I live by Jackson HWY (16). I have been excessive with my reports through my AT&T iPhone app "Mark The Spot". After 6 months of reports for only about 10% of the issues (I have so many issue here 10% was a lot :eek: of reporting!) I've experience they sent me a message letting me know that my reports helped pinpoint a tower issues and it will be replaced in a few weeks!
I know AT&T has issues, but I'd like to see if Verizon would actually do something like this! I am not happy with the network experience I've had here, but I am really happy to see that my voice was heard from a large company using innovative tools created by them on my iPhone.
I can tell that the tower is currently being worked on, because my service is getting worse. It won't be long now that I'll finally be able to a constant signal and hopefully no more dropped calls.
Before I received the message that they would replace the tower I ordered an AT&T micro cell. I think I'll install it anyway just to see how it will improve my coverage. This also brings up another point that they are giving us the ability to fix coverage issues with the Micro Cell they are offering. I know it's $150 (expensive), but at least they are offering an alternative for you.
One thing I've noticed as a customer is any aspect of the New AT&T that was legacy Cingular seems in the most part to be fine. It's all the junk they merged in from the legacy AT&T Wireless. This goes for call centers, towers, policies, etc. If I call customer service and have an excellent experience I'll ask the rep, "Are you legacy Cingluar or AT&T?" Every time they say Cingular. Of course if I have the opposite and ask "Are you legacy Cingluar or AT&T?" They either don't know what the word legacy means (which I then have to explain) or they say of course AT&T! I wish Cingular stayed Cingular and let AT&T die off! Legacy AT&T is the cancer in the New AT&T which is just Cingular with AT&T's name.
It's silly to think that the AT&T name is so valuable that they'd buy the crappy company just to use their stupid :eek: name. Who cares if AT&T is as recognizable as Coca Cola overseas?! Why not be so great at what you do that your name (Cingular), becomes as recognizable as Coca Cola! Cingular shouldn't have bought recognition... they should have tried to earn it! If they had tried to earn their recognition we wouldn't have Legacy AT&T's cancer in our cell phone company!:(

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.

Also, Apple doesn't make the charts; I don't get how it's strange to compare a platform to another platform. I think it's stranger to compare a single device to an entire platform.
Simple. Comparing Phone to Phone, may show an Android "win". Comparing All Android devices to IOS devices would not show the same win, as the tablet market is still currently dominated by IOS. Why on earth would they want to show something that makes "their side" look bad?

If I was running upcomming Leopard OSX, a few osx apps, the full upcoming CS3 Suite (not necessarily Batch Processing), have After Effects rendering a 30 minute clip in the background, downloading *legal torrents, watching internet tv (muted), while burning a DVD and listening to music..
That keeping in mind I won't necessariy be rendering-multiple scenes, while encoding, batch processing with a multiple of applications while running SETI@home ;) .... yet
Would that kind of Multi-tasking benefit through Multi-threading on the Octobot's 8-Cores..
Or slighly / not significant enough to warrant Going Octo over Quad..IMHO Definitely. With the Quad each process you describe will run slower and/or flat out bog down the Mac so you can't even word process without waiting for characters to appear. I know this 'cause I already have this happening to me a lot on the Quad G5.

In Windows 7 you not only have the option to switch it on and off, you can also customize the intrusiveness of it, I find it much more user friendly than in OS X.
Switching off or turning down UAC in Windows also equally impacts the strength of MIC (Windows sandboxing mechanism) because it functions based on inherited permissions. Unix DAC in Mac OS X functions via inherited permissions but MAC (mandatory access controls -> OS X sandbox) does not. Windows does not have a sandbox like OS X.
UAC, by default, does not use a unique identifier (password) so it is more susceptible to attacks the rely on spoofing prompts that appear to be unrelated to UAC to steal authentication. If a password is attached to authentication, these spoofed prompts fail to work.
Having a password associated with permissions has other benefits as well.
So Safari auto-downloads, unarchives and auto-executes something, but you think it is safe because it's an installer ? :confused:
If "Open safe files after downloading" is turned on, it will both unarchive the zip file and launch the installer. Installers are marked as safe to launch because require authentication to complete installation.
I'm sorry, but I'm still curious about the "auto-execute" part. Why would it run the installer automatically after decompressing it. That sounds quite "unsafe" to me. Even without administrator privilege, that means code can still run that can affect the current user's account.
No harm can be done from just launching the installer. But, you are correct in that code is being executed in user space.
Code run in user space is used to achieve privilege escalation via exploitation or social engineering (trick user to authenticate -> as in this malware). There is very little that can be done beyond prank style attacks with only user level access. System level access is required for usefully dangerous malware install, such as keyloggers that can log protected passwords. This is why there is little malware for Mac OS X. Achieving system level access to Windows via exploitation is much easier.
Webkit2 will further reduce the possibility of even achieving user level access.

These groups don't care at all about the environment. They only want to hinder businesses. These are the same groups that protest plans and lobby politicians to stop building power plants and refineries so the existing ones can be over worked (lower efficiency) and not allow for downtime for maintenance, further lowering efficiency. These groups have an agenda that has nothing to do with the environment. I believe that Apple does just fine, as do many other companies. I'll gladly buy my Merom MBP and sell my Rev E 17" pbg4 as soon as Apple makes it available to me. :)
Oh yeah? Please kindly explain to all of us just what the "real agenda" of these "evil groups" such as Greenpeace is...

All I'm going to say is that Apple isn't doing enough to keep iPhone users...well, iPhone users!
Two of my cousins now own droids. One had an iPhone and got a Droid once he started working at a Verizon store. The damn phone is jampacked with features that Apple refuses to include.
In order for Apple to improve their device, they must first be beaten. Otherwise, they will sit on their asses just watching the cash come in. They do it with their current line of computers and they are doing it now.
I love my iPhone but I think it is just that time. Hopefully they can come back. It is time to loosen their grip on the App Store, let Google do their "thang" and add numerous features that are available NATIVELY!
