Comment Re:Support them from your own money (Score 1) 666

Preface: I play with RedHat at work, and CentOS at home...

All fine, except if the system isn't for Oracle products then the vendor supporting the app will look at you funny when you tell them what enterprise OS you're running on.

RHEL has a certification relationship with many vendors. OVM, CentOS, and even to some degree Fedora, while being very similar as far as the administrator is concerned, are completely different when it comes to what level of supportability you'll get. At least 2 of those won't be particularly interested.

Of course, if you're supporting your own custom application then the answer is to run whatever OS you're comfortable with. If you want RedHat to look as a matter of priority at a technical problem you're having that is say related to their kernel, you'll have to pay them the license fee for that level of support. If your CIO wants a vendor to take some accountability, it has to cost something...

Then there are the certain applications that check the contents of your /etc/redhat-release file, and if they aren't happy with the answer, they'll refuse to go on. Of course, that's only a text file that any superuser can create. :)

So... ummm, can you tell me what the wind speeds were for the handful of hours prior to the reported elevated levels, or even how long the elevated level was recorded for in Tokyo? I'm only particularly interested in facts to prove me wrong, not speculation. :)

Nobody really bothers with reporting good news (great news, yes, good news doesn't sell). Bad news of any kind loves to spin. If the radiation levels vary significantly over even the next week (this must include going down) then there are no dangerous radioactive materials involved - such things have significantly higher half lives than seconds, minutes, or hours... even days.

Despite the explosions, this "disaster" is still officially at least 1 level lower than TMI ever was, and that was more bark than bite. No meltdown. Some heavy-ish elements in the reactor may be somewhat dangerous to get close to for a while, and if they escape they will be of mild concern because they can't sustain a reaction like you get in a nuclear reactor, whether it be for power (Uranium/Plutonium and other scary stuff) or medicine (not so scary, but still troublesome to carry lumps in your pocket). The half-life of those materials within the reactor will be what determines the time it takes from the control rods being inserted to the reactor going cold (and yes there will be significant residual radiation inside the reactor in normal circumstances). Current temperatures within the reactor simply won't be high enough to vaporize much that could be a threat. It's just better for you not to inhale the stuff that is out there, just as it's better for you not to inhale cigarette smoke.

Math fail... firstly, pounds??? The units we're interested in are milli/microsieverts. Who's talking pounds? Look up the unit, you'll find Wikipedia has useful information on what constitutes a danger... look it up and repeat after me: Oh, it's not all that bad.

Secondly, think beyond the narrow-minded figure that "minutes" means no more than 10 minutes...

Say the half life of the radioactive gasses escaping the power station is 30 minutes. yes, 30. It's not unthinkable. In that case 400 millisieverts (reported to be an exposure at the reactor) becomes 25 millisieverts after 2 hours, or ~1.5 millisieverts after 4 hours, or somewhere in the region of reported levels in Tokyo after 5 hours or so. Is a 50km/h sea breeze enough for you in a tropical region? This means the radioactive material in the atmosphere is decaying fast enough not to pose a significant health issue. If there is enough exposure to worry about, people start taking iodine pills. Sure, iodine pills have even been distributed around the area, but how many have actually been taken so far? Possibly that one exposed worker, and whoever decided to panic. Yes, we're still quite peachy. Conventional fuel based explosions have happened at a nuclear power plant, because a byproduct of the residual reaction is an ideal, carbon-free, fuel (H2), and it ignited. When the reactor shutdowns, which have been hampered by the problems at the plant, complete, then the properly protected experts can have a look and the full story on how much dangerous nuclear matter has been released into the atmosphere will come out. I think you'll find it's negligible. The Japanese should be worrying about other things than the potential for a nuclear holocaust.

*sigh* ... half life of minutes means it halves radiation level measured every so many minutes, doesn't mean it disappears in minutes. Revise your math based on that.

Generally the most dangerous nuclear material is that with a half life comparable to the lifespan of a human, ie decades. Yes there are spikes of radiation, but they dissipate quickly. 23 times the normal levels? I receive a day's worth of background radiation in an hour... as long as that doesn't happen for a month it's not likely to affect my health.

The real problem is if the nuclear fuel escapes into the atmosphere - that's where you end up with clouds that are dangerous. It hasn't happened in Japan yet, despite the physical assault the earth has thrown at it. Radioactive gases have been vented, and are short lived, and low risk because it's total exposure to radiation that causes the real health issues.

So far I still only see reports of one worker exposed to levels of radiation that are equivalent to a few years worth of radiation in an hour. That person may get cancer, and has every right to be worried, but you can get cancer from inhaling coal dust too. Or smoking, or, depending on what the media wants to pick up and run with, eating potatoes, or breathing. The point is, don't believe the hype that the media is using to sell stories. They don't seem to know what they're talking about. As soon as someone admits "radiation leak" the media broadcasts "Chernobyl" and the average Joe starts overreacting. These stories are alarmist, pure and simple, and it's selling newspapers and online advertising, while at the same time putting enough fear into people to affect the rescue and recovery efforts from the natural disaster.

I were in Tokyo I'd keep an eye out for any official reports about a genuine containment failure, while continuing to live my life.

Oh yes, those who use this as a tool to fear nuclear power need also to remember that this is a 40 year old plant, and there is new technology in such things which prevents the chance of even a partial meltdown, period. Very clever stuff where the fuel is embedded in material that expands as it gets too hot, which effectively moderates the fission reaction and prevents it going past a certain point.

I think we'll find the risks associated with earthquakes and tsunamis at say a gas or coal powered power station would be about the same. This tangent seems to have completely forgotten the magnitude of mother nature's fury which caused the issues in the first place.

Thousands were dead in minutes, and people seem to be insinuating that a fatality and some injuries after the natural disasters are beyond what might be considered statistically normal. Accidents happen, however unfortunate they may be.

Comment Re:Meltdown? (Score 1) 691

Bollocks. While the outcome was not ideal, the evacuations were just precautionary.

The reason for the explosions is due to the knowledge that the hydrogen/oxygen gas mix released would be marginally radioactive with a half life measured in seconds, and the intent was to contain the gas for long enough for it to be rendered inert. The risk of explosion was acknowledged, people were warned, and when when it did blow, well they had had opportunity to move people further away than they were. The escaping gases ARE raising radiation levels ... a bit. However, I think you'll find the radiation doses astronauts get are higher than those the bunnies outside the fences of the nuclear power plants are getting.

It takes a few days for a reactor that has had the control rods slammed into the shutdown position to cool down, and in the meantime the generator still generates some heat and needs some cooling. When the backups and backups of backups failed, they chose the less desirable route, in pumping in sea water. As it ain't pure water, you end up with slightly more radioactive matter with a half-life which is more like minutes than seconds, so less desirable, somewhat radioactive gas results, which is harmless well before it travels that 30km. There will be no noteworthy radioactive residue when the cool down is complete, except for what's in the reactor itself.

The reactor everyone's jumping up and down about has survived an earthquake and tsunami well beyond design spec, and as for the inconvenience of lost power. Yes, they lost backup and backup backup diesel generators, but they also had battery backups which held until mobile generators could be moved in. I also dare anyone to tell me what power generation scheme in that location at that time would not have failed, so of course there will be power rationing and/or blackouts.

The Japanese got the sum of their design and processes of their nuclear reactors right, and they are taking every precaution they can to ensure public safety. The biggest mistake was trying to contain the gas from the reactor instead of venting to the atmosphere, because the media are making it look like these gas explosions might be a sign that a meltdown is imminent. It isn't, but the media never let facts get in the way of a good story. Those responsible for the reactors are simply Doing The Right Thing [TM].

Warner Bros. Acquires Turbine 57

NNUfergs writes with news that Warner Bros. Home Entertainment Group has acquired Turbine Inc., creators of Lord of the Rings Online, Asheron's Call, and Dungeons & Dragons Online. Terms were not disclosed, but the Boston Globe claims the price was somewhere around $160 million. "Warner Bros. Interactive has bought a number of game development houses in recent years, in a bid to become a major power in video gaming. In 2007, the company purchased TT Games, a British firm that develops family-friendly products like Lego Star Wars and Lego Batman. In 2009, Warner Bros. bought the assets of bankrupt Chicago game company Midway, maker of the popular Mortal Kombat games. And earlier this year, it acquired a majority stake in Rocksteady Studios, another British developer, which created the hit game Batman: Arkham Asylum. ... Acquiring Turbine will give Warner Bros. total control over all future video games based on author J.R.R. Tolkien's beloved Lord of the Rings novels. Turbine holds an exclusive license to make an Internet-based game based on the books, while last year, Warner Bros. won a license to make non-Internet-based Tolkien video games."

Endangered Species Condoms 61

The Center for Biological Diversity wants to help put a polar bear in your pants with their endangered species condom campaign. They hope that giving away 100,000 free Endangered Species Condoms across the country will highlight how unsustainable human population growth is driving species to extinction, and instill the sexual prowess of the coquí guajón rock frog, nature's most passionate lover, in the condom users. From the article: "To help people understand the impact of overpopulation on other species, and to give them a chance to take action in their own lives, the Center is distributing free packets of Endangered Species Condoms depicting six separate species: the polar bear, snail darter, spotted owl, American burying beetle, jaguar, and coquí guajón rock frog."

Interestingly, not only is the development cross-platform friendly, but the game itself (a simple Indiana Jones platformer was demoed) saves its place and lets you resume from that spot on whichever platform you happen to pick up."
