AC/DC Music Attracts Great White Sharks 89

bazzalunatic writes "It turns out great white sharks can be lured underwater to cages by playing hits from AC/DC — specifically 'Shook me all night long'. Matt Waller, a shark diving tour operator in Australia, has found this curious fact. But it's not just any song, as the sharks weren't attracted by other tunes. Matt suspects the sharks are attracted to the low frequencies found in AC/DC's music. One wonders if they'll be turned off by Celine Dion music — a new type of shark repellent perhaps?"

Apple Asks Security Experts To Examine OS X Lion 417

An anonymous reader writes "For as much as Mac OS X has a reputation for being safer than Windows, security researchers won't hesitate to point out that the opposite is, in fact, true. But Apple's looking to change that. This past Thursday, Apple doled out a beta of OS X Lion to developers. In conjunction with that, Apple is also reaching out to noted security experts and offering them free previews of OS X 10.7 so that they can take a look at Apple's new security measures and reach back to Apple with any thoughts and concerns they might have. Indeed, Apple is becoming a lot more security conscious these days, not only in terms of reaching out to security researchers but also in its personnel hires."

'Anonymous' WikiLeaks Proponents Not So Anonymous 390

Giovane Moura writes "For a number of days the websites of MasterCard, Visa, PayPal and others are attacked by a group of WikiLeaks supporters (hacktivists). Although the group calls itself 'Anonymous,' researchers at the DACS group of the University of Twente (UT), the Netherlands, discovered that these hacktivists are easy traceable (PDF), and therefore anything but anonymous. The LOIC (Low Orbit Ion Cannon) software, which is used by the hacktivists, was analyzed by UT researchers, who concluded that the attacks generated by this tool are relatively simple and unveil the identity of the attacker. If hacktivists use this tool directly from their own machines, instead of via anonymization networks such as Tor, the Internet address of the attacker is included in every Internet message being transmitted. In the tools no sophisticated techniques are used, such as IP-spoofing, in which the source address of others is used, or reflected attacks, in which attacks go via third party systems.

60 Years of Hamming Codes 66

swandives writes "In 1950 Bell Labs researcher Richard W. Hamming made a discovery that would lay an important foundation for the modern computing and communications industries — coming up with a method for performing computing operations on a large scale without errors. Hamming wrote about how self-checking circuits help eliminate errors in telephone central offices. He speculated the 'special codes' he proposed — which became known as Hamming codes — would only need to be applied to systems requiring unattended operation for long periods or 'extremely large and tightly integrated' systems where a single failure would incapacitate the entire installation. Hamming code was the first discovery in an immense field called coding theory. This article looks back on the history of Hamming codes, their applications, and includes interviews with Todd Moon, Professor of electrical and computer engineering at Utah State University and David MacKay, Professor of natural philosophy in the department of Physics at the University of Cambridge and chief scientific adviser to the UK Department of Energy and Climate Change. An interesting read, about a little-known but fundamental element of information theory."

Was There Only One Big Bang? 295

goldaryn writes "Physorg.com is running an interesting story about the work of Oxford-based theoretical physicist Roger Penrose. Penrose has been studying CWB radiation and believes it's possible that space and time did not come into being at the Big Bang but that our universe in fact continually cycles through a series of 'aeons.' He believes that he has found evidence supporting his theory that the universe infinitely cycles."

Prepare To Be Watched While You Watch a Movie 433

BussyB writes "Gaining entry to some movie theaters lately gives patrons an experience that is on par with going through a TSA security checkpoint at the airport. Then once you've gained access, there are cameras strategically positioned that record your every move. Unfortunately, the extent to which these companies monitor movie-goers is only going to get worse."

Study Shows Testosterone is Bad For High-Stakes Decisions 213

itwbennett writes "According to a study by researchers at the University of British Columbia's Sauder School of Business, young CEOs with higher levels of testosterone in their system are 'more likely to initiate, scrap or resist mergers and acquisitions' — even when it's not in their best interest. 'We find a strong association between male CEOs being young and their withdrawal rate of initiated mergers and acquisition,' says Prof. Levi, whose research relies on the established correlation between relative youth and increased levels of testosterone. 'For instance, young CEOs, who have higher levels of testosterone, tend to reject offers even when this is against their interest.'"

HP CEO's Browsing History Used Against Him 230

theodp writes "Anything you browse can and will be used against you. An investigation of ousted HP CEO Mark Hurd's surfing history reportedly convinced the HP Board that Hurd had had a personal relationship with sexual harassment accuser Jodie Fisher, even if not sexual. Just the latest example of how HP 'work[s] together to create a culture of inclusion built on trust, respect and dignity for all.' The WSJ reported a person close to the investigation said Hurd had looked at clips from racy films featuring Ms. Fisher, a former actress, while someone 'familiar with Mr. Hurd's thinking' said he merely did a Google search of 10 minutes or so. One wonders how many more 'personal relationships' with Ms. Fisher the browser histories of HP's 304,000 worldwide employees might reveal. BTW, nice to see that Hurd has made it to HP's ex-CEO-Hall-of-Fame page."

Groovy For Domain-Specific Languages 81

RickJWagner writes "This is a book targeted primarily towards the Java programmer who doesn't yet know Groovy. Groovy is a dynamic scripting language that runs on the JVM and offers easy integration with the Java language. Groovy also offers dynamic language features that lend themselves to the creation of DSLs (Domain-Specific Languages). This book attempts to simultaneously teach the reader how to use Groovy and how to build a DSL." Keep reading for the rest of RickJWagner's review.

Wikipedia To Unlock Frequently Vandalized Pages 244

netbuzz writes "In an effort to encourage greater participation, Wikipedia, the self-described 'online encyclopedia that anyone can edit,' is turning to tighter editorial control as a substitute for simply 'locking' those entries that frequently attract mischief makers and ideologues. The new system, which will apply to a maximum of 2,000 most-vulnerable pages, is sure to create controversies of its own."

Microsoft Lost Search War By Ignoring the Long Tail 267

Art3x writes "When developing search engine technology, Microsoft focused on returning good results for popular queries but ignored the minor ones. 'It turned out the long tail was much more important,' said Bing's Yusuf Mehdi. 'One-third of queries that show up on Bing, it's the first time we've ever seen that query.' Yet the long tail is what makes most of Google's money. Microsoft is so far behind now that they won't crush Google, but they hope to live side by side, with Bing specializing in transactions like plane tickets, said Bing Director Stefan Weitz."

Facebook Goes After Greasemonkey Script Developer 375

palmerj3 writes "The popular Facebook Purity greasemonkey script (now renamed Fluff Buster Purity) has been used by thousands to rid their Facebook feeds from the likes of Mafia Wars, Farmville, and other annoying things. Now, Facebook is threatening the developer of this script. Does Facebook have the right to govern their website's design and functionality once it's in the browser?"

Microsoft Employees Love Their iPhones 366

portscan writes "There is an entertaining and telling article in the Wall Street Journal about iPhone use by Microsoft employees. Apparently, despite it being frowned upon by senior management, iPhone use is rampant among the Redmond rank and file. The head of Microsoft's mobile division tried to explain it away as employees wanting 'to better understand the competition,' although few believe this. Nowhere does the article mention attempts by the company to understand why the iPhone is more attractive to much of Microsoft's tech-savvy workforce than the company's own products."

First Creation of Anti-Strange Hypernuclei 179

runagate writes "Brookhaven National Laboratory has created a heretofore unknown form of matter. The matter we normally encounter, and are composed of, has nuclei of protons and neutrons that contain no strange quarks. It was known that anti-strange matter could exist, and using the Solenoidal Tracker at Brookhaven's RHIC, scientists detected a couple of dozen instances of antihypernuclei. The 'Z' axis of the Periodic Table has already been extended in the positive direction by the discovery of hypernuclei, but this new discovery extends it in the negative direction for this new type of 'strange' antimatter — which may exist in the core of collapsed stars and may provide insight into why our universe appears to be made almost solely of matter and not antimatter." The Register's coverage reproduces a helpful diagram.
