Of course, all of those problems were always blamed on others and never on the community - ex. not getting education because it was a “white” thing and then being angry and pissed when the only jobs they can get are janitors which then lead to more rancor and beliefs about being oppressed and what not.

Dr Felipe Ortega reported that only 1% of edits by random users were kept. “They were all unspeakable shit,” said burnt-out administrator WikiFiddler451. “All of them. No, I’m not exaggerating. Go to Special:Newpages and read a day’s entries some time. You’ll start by deleting the whole database, before you get onto plotting the doom of humanity. Christ, why go on?”

Recent media coverage has highlighted the “inclusionist/deletionist” wars of 2005, including enquiries from Endemol looking for a “passionate deletionist” to join Big Brother 11, “preferably one with big tits.” It is thought that Wikipedia could have had ten million articles by now had they not viciously abused their editorial powers by deleting your valuable contributions about you, your teacher at school, your garage band or your dog or the many cameraphone pictures you uploaded of your penis.

After a bit of searching (trying Gentoo, Gobo and Arch along the way), I decided to use something that isn’t Linux. Long story short: I narrowed the choices down to OpenSolaris and FreeBSD, but now I’m stuck. OpenSolaris is commercially backed by Sun, has nice enterprise-y tools in the default install, and best of all, a mature implementation of ZFS. FreeBSD is backed by a foundation, has a minimal default install and a rather new (but recently improved in the 8.0 release) implementation of ZFS, however it offers the Ports Collection (I quite like the performance boost due to compiling from source, no matter how small it might be) and a bigger community than OpenSolaris. That is just a minimal mention of the differences. I would be interested to see what the Slashdot community thinks of these two operating systems.”

Re:Performance boost? - by shutdown -p now (Score: 5, Informative) Thread

For x86, you may get a very slight boost, because binaries in conservative distros/OSes (like FreeBSD) are still typically compiled for i686. Turning SSE and other such stuff on can let gcc generate more optimal code, particularly when floating point is involved.

On x64, it is of course quite meaningless.

In practice, either way, it’s not worth the hassle at all.

Lightening 
Auroras 
Lightening bugs, etc 
Foxfire, etc 
Fish (or were they too deep then?)

So everything the human eye ever saw was reflected light. Since the advent of the television, people began watching and focusing on emitted light directly, and computers, cell phones, etc have taken that even further.

So what, if anything, does that mean to human vision?

Absolutely nothing, light is light, irrespective of the source.

Re:The problem with an OLED e-reader is the E. - by Fallen Seraph (Score: 5, Informative) Thread
There’s something noticeably absent from that list: the Moon. The moon was mankind’s primary source of light before the advent of fire, and the moon can be very bright at times. Yet the moon’s light is entirely composed of reflected light. The poster above you is correct: light is light, irrespective of the source. The key aspect is how bright the light is. Staring at the sun is bad, not because it’s a light source, but because it’s a POWERFUL light source which is much brighter than our eyes are capable of handling directly. With many modern devices, brightness can be varied for increased eye comfort and reduced strain.  
 
That being said, the issue is that, often, reducing brightness also reduces contrast on light emitting devices. And when the brightness is high, it can wash out the darker colors, and make details hard to see because the light overwhelms it. Thus E-Ink is useful not because it’s not a light source, but because it is a low brightness (when reading under reflected light) high contrast display, which uses almost no energy when the display is static, making it perfect for long-term reading.

To anyone familiar with how the immune system works, this appears to be a synthetic lymph node, an intriguing bit of biomimicry. From the Science Daily article: ‘A cancer vaccine carried into the body on a carefully engineered, fingernail-sized implant is the first to successfully eliminate tumors in mammals, scientists recently reported in the journal Science Translational Medicine. The new approach, pioneered by bioengineers and immunologists at Harvard University, uses plastic disks impregnated with tumor-specific antigens and implanted under the skin to reprogram the mammalian immune system to attack tumors. The new paper describes the use of such implants to eradicate melanoma tumors in mice. … The slender implants… are 8.5 millimeters in diameter and made of an FDA-approved biodegradable polymer. Ninety percent air, the disks are highly permeable to immune cells and release cytokines, powerful recruiters of immune-system messengers called dendritic cells. These cells enter an implant’s pores, where they are exposed to antigens specific to the type of tumor being targeted. The dendritic cells then report to nearby lymph nodes, where they direct the immune system’s T cells to hunt down and kill tumor cells.’”

People are debating the wrong question - by sp3d2orbit (Score: 5, Insightful) Thread

“Global warming is caused by CO2 and the CO2 comes from human sources. ”

Most intelligent people who have researched the issue have come to this conclusion.

“Curtailing carbon emissions is the only way to prevent further global warming.”

Intelligent people should immediately recognize the fallacy in this statement. Curtailing carbon emissions is but ONE possible response, it is not the only response and it is not necessarily the best response. The debate, at this point in time, should focus on the response. “Believing” in global warming does not need to translate into “believing” politicians can fix it with more power.

What is wrong with giving the government(s) power to curtail carbon emissions?

For one, it gives the government control of every faculty of human life. Almost everything we do, from eating, to breathing, breeding, and working has a carbon footprint. Giving the government control of carbon emissions gives the government control of everything. Students of history should recognize this pattern very well. An external force will harm us all unless the government is given enough power to protect us. Governments don’t protect, they repress. What happens if the government decides large dogs have too much of a carbon footprint. Or horses? Or more than one child?

Secondly, cutting emissions in the US will do nothing about China and India. In fact, cutting oil consumption in the US will make oil cheaper for third world factories. It is supply and demand. Personally, I would rather see the fossil fuels burnt in the US, under EPA standards, creating American jobs than to have it sent to China or India where it will be used in a much less efficient manner.

Third, it is unclear that cutting carbon emissions drastically in the near future will save us from tragedy. Global warming proponents admit this, but still advocate cutting emissions for lack of a better alternative.

What is the alternative?

While it isn’t my preferred approach, one alternative is to do nothing. Absolutely nothing. Oceans will rise, the world will get hotter, and people will adapt. All of the carbon we are pumping out of the ground and burning once existed in the atmosphere anyways. Plants and animals consumed it, fell to the ocean floor, and were buried under ground. The world survived with extra carbon in the past and could again. The Earth is not going to turn into Venus, no matter how much oil we burn.

Of course there will be costs for doing nothing. For one, a lot of very wealthy people are going to lose their expensive beach front properties. Many bailed out bankers will see their mansions succumb to the tides. Tough shit.

A lot of poor people, mostly in third world countries will have to move. Even in the US we may have to move certain cities like New Orleans instead of spending hundreds of billions of dollars trying to wall them off from the seas. This will be expensive, but probably less expensive than curtailing global emissions enough to have an effect.

Arable farming land will lost. Some will be gained, but overall there will probably be a decrease in the amount of land available for agriculture. Farmers may have to stop selling their prime lots to housing developments. People may have to stop bitching about genetically modified food and learn to adapt. But most people will not starve to death, we will adapt.

Is there a better solution than doing nothing?

Like I said, I am not a proponent of doing nothing. I think we should do something that actually stands a chance of working. The best way (notice how I didn’t use the word “only” here) to curtail carbon emissions is to give people cheaper options. I don’t mean solar or wind, or osmosis generators or tide machines or biofuel or nuclear fission.

Perhaps I have read one to many sci-fi novels, but I think we should take the hundreds of billions being spent on cutting emissions and put it into nuclear fusion research. If nuclear fusion can be perfected in the next decade or two then there will be no reason to burn fossil fuels, conserve energy, or give the government a fascist grip on the economy.

Forcing people into impoverished lives - by Kohath (Score: 4, Insightful) Thread

The real AGW arguments (and the motivation of all the parties involved) seem to be about the remedies rather than the climate. The AGW believers want to use governments to force people to lead objectively poorer lives. Many of them have wanted this since before Global Warming was even theorized.

They demand the power to do this, but they refuse to release their data. They refuse to publish the code for their computer models. They refuse to rationally refute skepticism. They refuse to understand human behavior as described by the discipline of Economics. They refuse to address the question of whether warmer may be better than colder. They refuse to identify the “correct” temperature, let alone describe how they arrived at that temperature. They refuse to close the loop on their proposed remedies to objectively weigh the benefits against the cost.

If Global Warming was simply an academic question rather than a life-or-death political struggle for power (or against power and for freedom), then it could be discussed as such.

AGW is going to lose the political struggle because of Climategate. It was already reeling from the fact that it hasn’t warmed in the last decade. And it faced an uphill battle due to the depression: rich people can afford to pay for environmental spirituality, poor people can’t. If the political struggle ends, this can go back to being about whether carbon release causes warming, and how much, and what it really means.

Being a scientist but not of the climate variety, I’ve got to say ‘No’. 
In a lot of cases, if not most, dialogue on the merits of your scientific work is simply impossible with a layperson. 
 
I work with this stuff. Every day. 40 (well more like 50-60) hours a week. It took years of study for me (and everyone else) 
just to get to the level where you can properly understand what it is, exactly, that I do. That’s what being an expert at something entails. 
Now when I get into a dispute with someone, they typically have the same level of expertise. They know more or less everything I do. I know what they’re saying, and they usually know what I’m saying. 
 
Now you bring into that situation some layperson with their religious reasons or ideological reasons or crank personality, who wants to dispute the results of my work. So they pore over it, and they simply don’t understand it. (And ignorance breeds arrogance more often than humility, as Lincoln said) But they think they do. And then they formulate their criticism. Even if that criticism makes sense (often not), it’s typically wrong at the most basic level. And that will practically always be the case - because there’s virtually *nothing* in the way of criticism that a beginner would be able to think of that an expert hadn’t thought about already. You’re just not going to find a professor of physics having made a mistake of forgetting the first law of thermodynamics. 
 
Now I’m happy to defend my science against legitimate, good, criticism. But a scientific debate is *NOT* where anybody should be TEACHING anybody science. What kind of ‘debate’ is it if every answer amounts to “That’s not what that word means, read a damn textbook.” It’s not the scientists who are being arrogant then. Hell, since when didn’t scientists bend over backwards to educate the public? We write textbooks, and popular-scientific accounts. Research gets published in journals for everyone to see, etc. It’s not like we’re keeping it a big secret - The problem is that some people are simply unwilling to learn, yet arrogant enough to believe they should be entitled to ‘debate’ with me, and that I should be personally burdened with educating them in the name of ‘open debate’! 
 
(Just to pick one out of the climate bag. How often haven’t you seen someone say “Yeah but climate change is cyclical!” - What? As if _climate scientists_ didn’t know that?! Refuting someone’s research with arguments from an introductory textbook) 
 
The fact that these climate-skeptics were prepared to take these e-mails, pore over them for some choice quotes (which didn’t even look incriminating to me out of context), blatantly misinterpret them without making any kind of good-faith effort to understand the context or the science behind it, and trumpet it all out as some kind of ‘disproval’ of global warming (which wouldn’t have been the case even if they were right), just goes to show that they’re simply not interested in either learning the science, or engaging in a real debate.

There were differences, for sure. But they all were similar. Why are they all similar? 
   
IT’S ALL A BIG CONSPIRACY BY THE CLIMATE SCIENTISTS!!!!! 
   
Well, except for the fact that we would love to rip the shit out of another organizations research. In that seven-model comparison, we were looking to rip apart some of the models. Where they were different, we did. Had we found one that was totally different from the rest, we would have figured out why, and published that. The fact of the matter is that the science is well settled.  
   
While I think you’re an asshat, I do agree with your last statement. It is a big pseudo-scientific world out there, provided you define “out there” as “in the media”. Those of us actually involved in science know that it’s not. You get ahead in science by taking heads. We know Darwin’s name because he wiped out hundreds of scientists’ work on biological diversity. We know Einstein’s name because he wiped out hundreds of theories on atomic interaction and the nature of space-time. We know Maxwell’s name because he invented coffee.  
   
As a scientist, surrounded with scientists, and friends with a lot of scientists, I can tell you, there’s nothing any of us would like to do than destroy the establishment. If I could disprove evolution, I’d do it in a heartbeat. If I could prove General Relativity wrong, I wouldn’t hesitate. It would put me in the text books. It would make me famous. If I could prove climate change wrong, I’d do the same.  
   
But I’m in the middle of that science. And I can’t. It’s solid, despite what the media makes it out to be. If it wasn’t, I’d be famous. You have to realize that most scientists want to know the truth. And as humans, we like nothing better than to be able to yell, DUMBASS in a very loud voice, while pointing at the dumbass so everyone notices. I believe in science because if I screw up, that will happen to me. So I try really hard not to screw up. As do all scientists. The ridicule of your peers is a very good tool to keep you honest.

As a result, they have these UPS “rooms” that hum like the dickens when you’re passing them in the hall, all with batteries that will need to be replaced regularly (just like the Google server battery systems, so it’s the same problem no matter what). Reason for the hum?

The hum is caused by these giant transformers that step the power from DC to AC and create 110 volts of AC current at whatever amperage is required for normal devices. But there is a lot of wasted energy in doing that.

Computers and servers all run off of DC power. They plug into AC power and then run that AC through a “power supply” that converts that to DC that the computer can use. That takes power, but power is plentiful when it comes from the power company and you pay your bill on time. But when you take the power from the power company, then change it to DC to charge batteries and then take power from those batteries to change it to AC to power normal wall outlets only to take that through a server’s power supply to change it to DC again for the computer to use it, you’re looking at lots of wasted energy in just changing from AC to DC, back and then back again, as well as changing to the kind of voltage and amperage needed to run the microprocessor, power the memory and power the drive arrays.

So this is all about lowering consumption. And if you lower consumption, you lower your electricity costs.

The hobbyist magazines were all aflutter some years ago about using photovoltaic (solar) energy to power a house. But what everyone had to do (early on) was to change their appliances (or order special ones) to run on DC — not because you couldn’t make AC current from the DC output of the photovoltaic systems but because it took a lot of energy to do that and these hobbyists were all about trying to save so much energy that they could take themselves off the grid.

Here, on a large scale, you see the same idea. It’s just more efficient to do this. And one of the big arguments in the early years of electrification was between DC power distribution (Thomas Edison) and AC power distribution (George Westinghouse and Nikola Tesla). We may wind up fighting these battles again in the near future.

Facebook says the move will slash its power bill and save millions in capital expenses on UPS systems and PDUs.

And it’ll move the complexity and unreliability to the server. The whole idea behind centralized UPS’s (and by the way, you still need PDUs) is that you have reliability, serviceability, and economies of scale and efficiency. Now you have to monitor and service the batteries in thousands of pieces of equipment. And guess what happens when one of those batteries fails by getting cooked? Sulfuric acid all over the place (yes, even the “sealed” lead acid batteries can fail and leak) instead of the batteries being in, say, a battery room. God help us if they use lithium-ion, which would introduce us to a world of server fires and water damage, since a lot of datacenters are now dry-pipe to save costs. Nevermind that batteries and their associated electronics take up space, and that space has to come from somewhere.

So, now you have each server getting more expensive, more complex with both hardware and software (server now needs its own battery power management) heavier, bigger, featuring toxic materials, and now non-standard, non-commodity design which vendors will charge more for as they specialize the equipment.

I’m sure this all looks great on a powerpoint slide simplified into “if we put batteries in our servers, we can throw out our expensive UPS and save money!” This is just another hot/stupid trend; just because Google is doing it, doesn’t make it brilliant. I stopped believing everything google was doing was a Best Practice around the same time gmail started going down for hours (and for some users, more than a day) at a time on a regular basis.

I tuned out of the article around the point where the guy from Facebook complains about cosmetic features interfering with airflow. Uh, guess what, bud? Dell’s pretty front panel has been optional (saving you a few bucks sometimes) for years.

Another idea behind a UPS is _a_single_point_of_failure_. Moving the power backups to the individual servers eliminates that worry. Plus, since the servers are already redundant, you don’t need the redundancy on the UPS, inverters, etc., which should save money. 
And since it’s long-term, I’m willing to wager it won’t be lead-acid, but NiMH. So no real maintenance issues. And your “what happens if…” scenarios apply equally to a battery in a megawatt UPS or a battery in a server. 
As for battery management and ‘specialized’ power supplies, etc.: go check out a laptop. That wheel has already been invented, and better yet, has benefitted from mass-production.

The best solution? - by LWATCDR (Score: 4, Interesting) Thread

This is interesting to me in a couple of ways. 
The idea is that it is cheaper to have just a battery instead of a UPS. A UPS will also have to have an inverter. 
Okay I can see this but they why have it at the server level? 
Remove the power supply from the server and put it at the rack level? Have a big redundant power supply for each rack and batteries for each rack? 
Or why not use DC for the entire data center and put the battery at the Data Center level? 
Seems to me that there may be more than one way to skin this cat and each have it’s pluses. If you are using a large number of low load balanced servers where having any one go down isn’t a disaster then putting the battery on the server would give you a good trade off. You are probably more likely to have a single server to fail than a more centralized system would but the odds of taking down the system would be tiny. 
I would love to see a study of the benefits of each type of system with the trade offs.

Noise graph of Life and Work On the LHC At CERN Life and Work On the LHC At CERN - by (46% noise) View Skip
An anonymous reader sends in a CNet Crave interview with a working physicist at CERN. The interview is full of detail about what it’s like to work in this geek paradise (if a bit dumbed-down for an audience assumed not very technical). Dr. Paul Jackson, a particle physicist working on the LHC’s Atlas experiment, says there’s no chance of black holes wiping us out, and that the time travel speculation is bunkum. He is 100% convinced that they will find the Higgs boson. The scientists there favor Macs, while computers in the control room are Linux-based. “What would happen if you were standing in front of the beam? You would die. It would be a pretty spectacular death, and you wouldn’t know a lot about it. … It would be the equivalent of having 87kg of TNT dumped into your body.”

So it was in 1978 that when the proton beam entered Anatoli Bugorski’s skull it measured about 200,000 rads, and when it exited, having collided with the inside of his head, it weighed in at about 300,000 rads. Bugorski, a 36-year-old researcher at the Institute for High Energy Physics in Protvino, was checking a piece of accelerator equipment that had malfunctioned - as had, apparently, the several safety mechanisms. Leaning over the piece of equipment, Bugorski stuck his head in the space through which the beam passes on its way from one part of the accelerator tube to the next and saw a flash brighter than a thousand suns. He felt no pain.

From what we know about radiation, about 500 to 600 rads is enough to kill a person (though we don’t know of anyone else who has been exposed to radiation in the form of a proton beam moving at about the speed of sound). The left side of his face swollen beyond recognition, Bugorski was taken to a clinic in Moscow so that doctors could observe his death over the following two to three weeks.

Over the next few days, skin on the back of his head and on his face just next to his left nostril peeled away to reveal the path the beam had burned through the skin, the skull, and the brain tissue. The inside of his head continued to burn away: all the nerves on the left were gone in two years, paralyzing that side of his face. Still, not only did Bugorski not die, but he remained a normally functioning human being, capable even of continuing in science. For the first dozen years, the only real evidence that something had gone neurologically awry were occasional petit mal seizures; over the last few years Bugorski has also had six grand mals. The dividing line of his life goes down the middle of his face: the right side has aged, while the left froze 19 years ago. When he concentrates, he wrinkles only half his forehead.

So you’re saying it’d be pretty painless? You could revolutionize flawed processes we have in the United States by providing an alternative that may have a more expensive start up cost but would solve budget problems by providing needed services for both our prison system and science research at the same time. I mean if we ignore the ethical problems with televised executions, the costs of an LHC could be mitigated by commercial segments

Yeah, even a few billion atoms (which isn’t very much at all) and you’re already talking about hundreds of Joules.

I forget the exact energy specifications of the LHC, but if you’re interested in getting a feeling for the power it packs, do a search for “LHC beam dump”. This is a huge block of solid material (some sort of a lead-composite, IIRC) that’s only job is to be vaporized if they need to shut down the beam quickly.

But EU justice and interior ministers are apparently keen [on agreeing to] a deal as soon as possible, on 30 November. Why 30 November? Because one day later, on 1 December 2009, the EU’s Lisbon Treaty will be in force and would allow the European Parliament to play a major role in the negotiations of the deal with the US. A deal one day before will be a slap in the face to democracy in the EU. … [W]hile the US will be able to access EU banking data, no access to US banking data by EU [authorities] is being foreseen.”

They’ll give access to all inter-bank transactions. The whole issue started with the revelation that US intelligence had access to SWIFT data through SWIFT’s US data center. SWIFT then shifted its operation to its other data centers and will cease channeling EU transaction data through the US data center by the end of the year. So the loss of access for the US spies is the SWIFT data, but the treaty will give them access to all inter-bank transactions, even those which are not processed by SWIFT. This is a classic rebound technique: The EU cannot spy on its own citizens like that, but they do get information back from US spies.

Who’s to blame? The US, for shamelessly exploiting the people they often call their friends? The EU council, for betraying their people? Why choose…

As far as I’m aware, the EU still takes more public money than any other organisation that has failed to produce audited accounts, and it’s been doing so for more than a decade now. I think we can safely assume that they are above the law. And if they’re not, as we’ve recently seen with the Lisbon treaty, they are quite capable of rewriting the law until they are, without needing any mandate from the people.

Also, there are lots of ways around Taxation laws, legally, that require NO money off-shore. Using Charity receipts, holding companies, and company expenses, you can essentially cut your profits down so you don’t get taxed as much while everything you want to purchase is owned by various companies (which you own but not directly).

It’s kind of like you run company A, and Company B owns your car, Company C owns your house, Company D buys food, etc etc, and while the paper trail exists, theres nothing illegal about it.
