Cracking Passwords With Amazon EC2 GPU Instances 217

Posted by CmdrTaco from the sekrit-p4ssw0rd dept.
suraj.sun writes "As of Nov. 15, 2010, Amazon EC2 is providing what they call 'Cluster GPU Instances': An instance in the Amazon cloud that provides you with the power of two NVIDIA Tesla 'Fermi' M2050 GPUs... Using the CUDA-Multiforce, I was able to crack all hashes from this file with a password length from 1-6 in only 49 Minutes (1 hour costs $2.10 by the way.). This is just another demonstration of the weakness of SHA1 — you really don't want to use it anymore."

The ~200 Line Linux Kernel Patch That Does Wonders 603

Posted by CmdrTaco from the well-isn't-that-special dept.
An anonymous reader writes "There is a relatively miniscule patch to the Linux kernel scheduler being queued up for Linux 2.6.38 that is proving to have dramatic results for those multi-tasking on the desktop. Phoronix is reporting the ~200 line Linux kernel patch that does wonders with before and after videos demonstrating the much-improved responsiveness and interactivity of the Linux desktop. While compiling the Linux kernel with 64 parallel jobs, 1080p video playback was still smooth, windows could be moved fluidly, and there was not nearly as much of a slowdown compared to when this patch was applied. Linus Torvalds has shared his thoughts on this patch: So I think this is firmly one of those 'real improvement' patches. Good job. Group scheduling goes from 'useful for some specific server loads' to 'that's a killer feature.'"

Shadow Scholar Details Student Cheating 542

Posted by Soulskill from the cloak-and-dagger-academia dept.
vortex2.71 writes "A 'shadow writer,' who lives on the East Coast, details how he makes a living writing papers for a custom-essay company and describes the extent of student cheating he has observed. In the course of editing his article, The Chronicle Of Higher Education reviewed correspondence he had with clients and some of the papers he had been paid to write. 'I've written toward a master's degree in cognitive psychology, a Ph.D. in sociology, and a handful of postgraduate credits in international diplomacy. I've worked on bachelor's degrees in hospitality, business administration, and accounting. I've written for courses in history, cinema, labor relations, pharmacology, theology, sports management, maritime security, airline services, sustainability, municipal budgeting, marketing, philosophy, ethics, Eastern religion, postmodern architecture, anthropology, literature, and public administration. I've attended three dozen online universities. I've completed 12 graduate theses of 50 pages or more. All for someone else.'"

Stuxnet Was Designed To Subtly Interfere With Uranium Enrichment 334

Posted by Soulskill from the well-thank-god-it-didn't-infect-my-pc dept.
ceswiedler writes "Wired is reporting that the Stuxnet worm was apparently designed to subtly interfere with uranium enrichment by periodically speeding or slowing specific frequency converter drives spinning between 807Hz and 1210Hz. The goal was not to cause a major malfunction (which would be quickly noticed), but rather to degrade the quality of the enriched uranium to the point where much of it wouldn't be useful in atomic weapons. Statistics from 2009 show that the number of enriched centrifuges operational in Iran mysteriously declined from about 4,700 to about 3,900 at around the time the worm was spreading in Iran."

The Story of My As-Yet-Unverified Impact Crater 250

Posted by Soulskill from the dent-in-the-world dept.
tetrahedrassface writes "When I was very young, my dad took me on a trip to his parents' farm. He wanted to show me 'The Crater.' We walked a long way through second generation hardwoods and finally stood on the rim of a hole that has no equal in this area. As I grew up, I became more interested in The Crater, and would always tell friends about it. It is roughly 1,200 feet across and 120 feet deep, and has a strange vibe about it. When you walk up to it, you feel like something really big happened here. Either the mother of all caves is down there, or a large object smashed into this place a long, long time ago. I bought aerial photos when I was twelve and later sent images from GIS to a geologist at a local university. He pretty much laughed me out of his office, saying that it was a sinkhole. He did wish me luck, however. It may be sinkhole. Who knows? Last week I borrowed a metal detector and went poking around, and have found the strangest shrapnel pieces I have ever seen. They are composed of a metal that reacts strongly to acids. The largest piece so far reacted with tap water and dish-washing detergent. My second trip today yielded lots of strange new pieces of metal, and hopefully, one day the truth will be known. Backyard science is so much fun. And who knows; if it is indeed a cave, maybe Cerberus resides there."

White House Pressuring Registrars To Block Sites 569

Posted by CmdrTaco from the strange-world-we-live-in dept.
An anonymous reader writes "While the Senate is still debating a bill that would force registrars and ISPs to block access to sites deemed 'infringing,' it appears that the White House's IP Czar is already holding meetings with ISPs, registrars and payment processors to start voluntarily blocking access to sites it doesn't like. Initially, they're focused on online pharmacies, but does anyone think it will only be limited to such sites? ICANN apparently has refused to attend the meetings, pointing out that they're 'inappropriate.' Doesn't it seem wrong for the US government to be pushing private companies to censor the Internet without due process?"

Hawking: No 'Theory of Everything' 465

Posted by CmdrTaco from the you-all-been-punked dept.
Flash Modin writes "In a Scientific American essay based on their new book A Grand Design, Stephen Hawking and Leonard Mlodinow are now claiming physicists may never find a theory of everything. Instead, they propose a 'family of interconnected theories' might emerge, with each describing a certain reality under specific conditions. The claim is a reversal for Hawking, who claimed in 1980 that there would be a unified theory by the turn of the century."

Russian Firm Plans Commercial Space Station 133

Posted by CmdrTaco from the love-to-visit-someday dept.
astroengine writes "Buoyed by plans for commercial space taxis, a Russian company plans to build and launch a privately owned outpost in orbit for tourists, scientists and other paying visitors. RSC Energia, which designed and built the Russian modules of the International Space Station, is partnering with Russian commercial space startup Orbital Technologies to manufacture the new hub, currently known as Commercial Space Station."

Many More Android Apps Leaking User Data 299

Posted by CmdrTaco from the because-they-can dept.
eldavojohn writes "After developing and using TaintDroid, several universities found that of 30 popular free Android apps, half were sharing GPS data and phone numbers with advertisers and remote servers. A few months ago, one app was sending phone numbers to a remote server in China but today the situation looks a lot more pervasive. In their paper (PDF), the researchers blasted Google saying 'Android's coarse grained access control provides insufficient protection against third-party applications seeking to collect sensitive data.' Google's response: 'Android has taken steps to inform users of this trust relationship and to limit the amount of trust a user must grant to any given application developer. We also provide developers with best practices about how to handle user data. We consistently advise users to only install apps they trust.'"

Linux May Need a Rewrite Beyond 48 Cores 462

Posted by CmdrTaco from the it's-all-stacking-blocks dept.
An anonymous reader writes "There is interesting new research coming out of MIT which suggests current operating systems are struggling with the addition of more cores to the CPU. It appears that the problem, which affects the available memory in a chip when multiple cores are working on the same chunks of data, is getting worse and may be hitting a peak somewhere in the neighborhood of 48 cores, when entirely new operating systems will be needed, the report says. Luckily, we aren't anywhere near 48 cores and there is some time left to come up with a new Linux (Windows?)."

Govt To Bomb Guam With Frozen Mice To Kill Snakes 229

Posted by samzenpus from the rodent-rain dept.
rhettb writes "In a spectacularly creative effort to rid Guam of the brown tree snake, an invasive species which has ravaged local wildlife and angered local residents, the US Department of Agriculture is planning to 'bomb' the island's rainforests with dead frozen mice laced with acetaminophen. While it might not seem difficult to purge an island of snakes, the snake's habit of dwelling high in the rainforest canopy has so far thwarted efforts to rid the island of the pest. Eradicating the snake is a priority because it triggers more than 100 power outages a year at a cost of $1-4 million and has driven at least 6 local bird species to extinction."

Father of Java, James Gosling Unloads 337

Posted by CmdrTaco from the java-and-java dept.
javab0y writes "The folks over at basementcoders did a podcast with James Gosling, The Father of Java, last week at a coffee shop in San Francisco during the JavaOne conference. In a raw and no-holds-barred interview, James let loose on Oracle, the Google Lawsuit, and his experience with IBM. You know its going to be good when he starts out saying, 'I eventually graduated in '83. Went to work for IBM which is, you know, is within the top 10 of my stupidest career decisions I've made.' The podcast was fully transcribed."

United Nations Names Ambassador To Aliens 306

Posted by CmdrTaco from the sounds-like-a-cushy-job dept.
Shag writes "Although searches for extraterrestrial intelligence have thus far come up empty-handed, the United Nations appears to be preparing for eventual 'first contact.' Many media outlets are carrying the story that Mazlan Othman, a Malaysian astrophysicist who heads the UN's Office for Outer Space Affairs in Vienna — already charged with things like keeping track of satellites to prevent Kessler Syndrome and coordinating the international response to any earth-impacting asteroids — will be the first person to meet with aliens if they do show up." Update: 09/27 16:42 GMT by S : Looks like this one's too good to be true — in an email to The Guardian, Othman said, "It sounds really cool but I have to deny it."

Selling Incandescent Light Bulbs As Heating Devices 557

Posted by samzenpus from the a-bulb-by-any-othe-name dept.
Csiko writes "The European Union has banned by law trading of incandescent light bulbs due to their bad efficiency/ecology (most of the energy is transformed into heat). A company is now trying to bypass this restriction by offering their incandescent light bulb products as a heating device (article in German) instead of a light device. Still, their 'heat balls' give light as well as heating. So — every law can be bypassed if you have some creativity!"

Supreme Court May Tune In To Music Download Case 339

Posted by samzenpus from the from-on-high dept.
droopus writes "The US Supreme Court is weighing into the first RIAA file-sharing case to reach its docket, requesting that the music labels' litigation arm respond to a case testing the so-called 'innocent infringer' defense to copyright infringement. The case pending before the justices concerns a federal appeals court's February decision ordering a university student to pay the Recording Industry Association of America $27,750 — $750 a track — for file-sharing 37 songs when she was a high school cheerleader. The appeals court decision reversed a Texas federal judge who, after concluding the youngster was an innocent infringer, ordered defendant Whitney Harper to pay $7,400 — or $200 per song. That's an amount well below the standard $750 fine required under the Copyright act. Harper is among the estimated 20,000 individuals the RIAA has sued for file-sharing music. The RIAA has decried Harper as 'vexatious,' because of her relentless legal jockeying."
