Ask Slashdot: Is SHA-512 the Way To Go? 223

crutchy writes "When I was setting up my secure website I got really paranoid about SSL encryption, so I created a certificate using OpenSSL for SHA-512 encryption. I don't know much about SHA (except bits that I can remember from Wikipedia), but I figure that if you're going to go to the trouble (or expense) of setting up SSL, you may as well go for the best you can get, right? Also, what would be the minimum level of encryption required for, say, online banking? I've read about how SHA-1 was 'broken', but from what I can tell it still takes many hours. What is the practical risk to the real internet from this capability? Would a sort of rolling key be a possible next step, where each SSL-encrypted stream has its own private/public key pair generated on the fly, and things like passwords and bank account numbers were broken up and sent in multiple streams with different private/public key pairs? This would of course require more server grunt to generate these keys (or we could take a leaf from Google's book and just have separate server clusters designed solely for that job), but then if computing performance was a limiting factor, the threat to security of these hashes wouldn't be a problem in the first place."

Obama Sets End of Iraq Combat For August 31st 659

eldavojohn writes "President Barack Obama has announced that on August 31st the United States will cease all combat operations in Iraq, although 50,000 troops will remain until the end of 2011. It's been a long seven-and-a-half years, with no guarantee of this announcement actually signifying the end of violence. Pundits are already speculating on whether or not this withdrawal speech is 'Mission Accomplished 2.' It's possibly the most significant confirmation of and commitment to a withdrawal the world will hear from the United States in Iraq."

Oil Leak Could Be Stopped With a Nuke 799

An anonymous reader writes "The oil leak in the Gulf of Mexico could be stopped with an underground nuclear blast, a Russian newspaper reports. Komsomoloskaya Pravda, the best-selling Russian daily, reports that in Soviet times such leaks were plugged with controlled nuclear blasts underground. The idea is simple, KP writes: 'The underground explosion moves the rock, presses on it, and, in essence, squeezes the well's channel.' It's so simple, in fact, that the Soviet Union used this method five times to deal with petrocalamities, and it only didn't work once."

Will Your Answers To the Census Stay Private? 902

Hugh Pickens writes "James Bovard writes in the Christian Science Monitor that Americans are told that information gathered in the census will never be used against them and the House of Representatives, in a Census Awareness Month resolution passed March 3, proclaimed that 'the data obtained from the census are protected under United States privacy laws.' Unfortunately, thousands of Americans who trusted the Census Bureau in the past lost their freedom as a result. In the 1940 Census, the Census Bureau loudly assured people that their responses would be kept confidential. Within four days of the attack on Pearl Harbor, the Census Bureau had produced a report listing the Japanese-American population in each county on the West Coast. The Census Bureau's report helped the US Army round up more than 100,000 Japanese-Americans for concentration camps (later renamed 'internment centers'). In 2003-04, the Census Bureau provided the Department of Homeland Security with a massive cache of information on how many Arab Americans lived in each ZIP Code around the nation, and which country they originated from — information that could have made it far easier to carry out the type of mass roundup that some conservatives advocated. 'Instead of viewing census critics as conspiracy theorists, the nation's political leaders should recognize how their policies have undermined public faith in government,' writes Bovard. 'All the census really needs to know is how many people live at each address. Citizens should refuse to answer any census question except for the number of residents.'"

California Legislature Declares "Cuss-Free" Week 262

shewfig writes "The California legislature, which previously tried to ban incandescent light bulbs, just added to the list of banned things ... swear words! Fortunately, the measure only applies for the first week of March, and compliance is voluntary — although, apparently, there will be a 'swear jar' in the Assembly and the Governor's mansion. No word yet on whether the Governator intends to comply."

FOSS Sexism Claims Met With Ire and Denial 1255

Last Friday Bryce Byfield gave us a little insight into the fallout surrounding his article on sexism in the FOSS world. Unfortunately it seems that FOSS junkies did little better than the rest of the world with respect to sexism, displaying similar levels of denial, abuse, and ignorance. "But the real flood of emotion comes from the anti-feminists and the average men who would like to deny the importance of feminist issues in FOSS. Raise the subject of sexism, and you are met with illogic that I can only compare to that of the tobacco companies trying to deny the link between their products and cancer. Because I took a feminist stance in public, I have been abused in every way possible — being called irrelevant, a saboteur, coward, homosexual, and even a betrayer of the community. I know that many women in the community have been attacked much more savagely than I have, so I'm not complaining. Nor am I a stranger to readers who disagree with me, but the depth of reaction has taken me back more than once. I think the reaction is an expression of denial more than anything else."

Fake News Scam Sites Advertising On Real News Sites 128

Virtual_Raider writes "Wired is running a story about a new twist in the never-ending quest to prove P. T. Barnum's adage. Old: Scammers are creating fake news sites that look almost like the real thing. New: They are advertising on real news sites, making it difficult for unwary readers to catch on they are being duped with fake coverage of get-rich-quick scams. Among those running the scam 'news' ads are the Huffington Post and Salon. From the article: 'The story has art, it has a sidebar, there's weather, supposed reader comments — even ads. Steadman is described as "a mother from San Francisco" — at least, when I read the article. Thanks to cutting-edge reporting techniques perfected by News 5, she will automatically move to the geolocation of your internet IP address when you read it. Look, she lives right in your neighborhood!'" Forbes also wrote about the scam news sites a couple of weeks back.

Submission + - Eric Raymond gets the clue stick from uber-hacker 11

An anonymous reader writes: Eric Raymond recently wrote to defend open-source innovation against the vicious attacks of some rabid proprietary software zealot. The guy later complains that ESR quoted him out of context, and that he exaggerates the role hackers played in the development of the web, drawing a parallel with his own role in 3D games. ESR, apparently very unimpressed, misses the clue entirely and goes all nuclear on him: "You are articulating the assumptions of someone who is merely talented. I, on the other hand, have known geniuses [...] I may actually be one myself." End of story? Not quite, here is the kicker. The guy responds: "To the best of my knowledge, there are less than 30 people on this planet who can claim having designed a successful operating system entirely from scratch[...]. I'm one of them." It turns out that ESR's "victim", not content with having written one of the earliest 3D game, is also behind HP's Itanium virtualization technology...

Submission + - Thank an Engineer

GaryOlson writes: "A little something TI is sending to its friends:
Check out the premiere of the "Thank an Engineer" short video series from Texas Instruments. These short spoofs demonstrate what the world would be like without the many engineering marvels you've been a part of creating.

We, at TI, wanted to send a quick "Thanks" your way and maybe get a laugh out of you while we were at it. And if you don't like them, well you can just ... give us a better idea and you just might win one of ten flip video cameras we're giving away by the end of the year!

40 Years Ago, the US Lost a Nuclear Bomb 470

Hugh Pickens writes "A BBC investigation has found that in 1968 the US abandoned a nuclear weapon beneath the ice in northern Greenland after a nuclear-armed B52 crashed on the ice a few miles from Thule Air Base. The Stratofortress disintegrated on impact with the sea ice and parts of it began to melt through to the fjord below. The high explosives surrounding the four nuclear weapons on board detonated without setting off the nuclear devices, which had not been armed by the crew. The Pentagon maintained that all four weapons had been 'destroyed' and while technically true, investigators piecing together fragments from the crash could only account for three of the weapons. Investigators found that 'something melted through ice such as burning primary or secondary.' A subsequent search by a US submarine was beset by technical problems and, as winter encroached and the ice began to freeze over, the search was abandoned. 'There was disappointment in what you might call a failure to return all of the components,' said a former nuclear weapons designer at the Los Alamos nuclear laboratory. 'It would be very difficult for anyone else to recover classified pieces if we couldn't find them.'"

Using Magnets To Turn Off the Brain's Speech Center 269

An editor for the Telegraph, Roger Highfield, recently volunteered to allow a UK researcher to shut off the speech center of his brain with a high-powered magnetic pulse. Regular speech is controlled by a section of the brain called Broca's area. Once the precise location is determined in the subject, a magnetic pulse can temporarily disrupt speech without impairing other cognitive functions. The link contains a video in which you can watch Highfield stutter and twitch while attempting to recite a nursery rhyme. A later test shows that he's able to sing the rhyme without difficulty, since singing is controlled in a different part of the brain (as you may remember from Scott Adams' speech disorder). Researchers believe that the ability to stimulate or quell activity in specific areas of the brain may help in treating conditions like epilepsy and migraine headaches.
