Facebook Patents the News Feed 96

Posted by ScuttleMonkey from the hope-for-narrow-focus dept.
daedae writes "It seems Facebook has been granted a patent for the news feed, as a method of monitoring activities, storing them in a database, and displaying an appropriate set of activities to an appropriate set of users. 'That sounds pretty broad, and the social-networking world was all atwitter at the possible ramifications. Writing for ReadWriteWeb, Marshall Kirkpatrick proclaimed, "This could be very big. ... MySpace, Flickr, Yahoo, Twitter (?), the sharing part of Google Reader, and even Google Buzz — do all of these sites have technology at the center of their social experiences that falls under this new patent of Facebook's?" The patent may not be that broad. Nick O'Neill at the All Facebook blog wrote that the patent doesn't appear to cover status updates as used by Twitter. "It appears that this patent surrounds implicit actions. This means status updates, which is what Twitter is based on, are not part of this patent. ... Instead, this is about stories about the actions of a user's friends. While still significant, the implications for competing social networks may be less substantial," O'Neill wrote.'"

Submission + - What has your phone survived? (togapit.com)

Submitted by NotAnIndividual
NotAnIndividual writes: On an ice fishing trip two months ago, I lost my iPhone somewhere in the snow. I searched and searched, but to no avail. But just this weekend when moving the ice hut, lo and behold there it was. I quickly threw it into a bag of rice and placed it under a lamp to defrost. Three hours later I plugged it in. I wasn't expecting much. I mean, really, it had been frozen in snow for the last two months! To my surprise, the Apple logo popped up. I put in the SIM card and voila, my iPhone was back. My apps, my contacts, my music and more importantly my life were back. And this is the same iPhone that I dropped in a cup of coffee a few months ago! This got me wondering how much damage a cell phone can actually take.

How have other slashdot users punished their phones without actually killing them completely?

Recommendation Algorithm Wants To Show You Something New 90

Posted by ScuttleMonkey from the try-it-you'll-like-it dept.
Several sources are reporting on a new metric that computer scientists are going after with respect to recommender systems — recommendation diversity. "In a paper that will be released by PNAS, a group of scientists are pushing the limits of recommendation systems, creating new algorithms that will make more tangential recommendations to users, which can help expand their interests, which will increase the longevity and utility of the recommendation system itself. Accuracy has long been the most prized measurement in recommending content, like movies, links, or music. However, computer scientists note that this type of system can narrow the field of interest for each user the more it is used. Improved accuracy can result in a strong filtering based on a user's interests, until the system can only recommend a small subset of all the content it has to offer."

Scientists Develop Financial Turing Test 184

Posted by ScuttleMonkey from the i-failed-the-turing-test dept.
KentuckyFC writes writes to share a new online test that is being touted as the "financial Turing test." The web-based exercise asks users to distinguish between real and randomly generated financial data. "Various economists argue that the efficiency of a market ought to be clearly evident in the returns it produces. They say that the more efficient it is, the more random its returns will be and a perfect market should be completely random. That would appear to give the lie to the widespread belief that humans are unable to tell the difference between financial market returns and, say, a sequence of coin tosses. However, there is good evidence that financial markets are not random (although they do not appear to be predictable either). Now a group of scientists have developed a financial Turing test to find out whether humans can distinguish real financial data from the same data randomly rearranged. Anybody can take the test and the results indicate that humans are actually rather good at this kind of pattern recognition."

Losing Google Would Hit Chinese Science Hard 161

Posted by ScuttleMonkey from the talk-to-your-government dept.
An anonymous reader writes to share recent statements by Chinese scientists that indicate troubled waters ahead if Google were to pull out of China. "More than three-quarters of scientists in China use the search engine Google as a primary research tool and say their work would be significantly hampered if they were to lose it, a survey showed on Wednesday. In the survey, 84 percent said losing Google would 'somewhat or significantly' hamper their research and 78 percent said international collaborations would be affected. 'Research without Google would be like life without electricity,' one Chinese scientist said in the survey, which asked more than 700 scientists for their views."

Submission + - California legislature declares "Cuss-Free" week (mercurynews.com)

Submitted by shewfig
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 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.

Saturn Moon Could Be Hospitable To Life 153

Posted by ScuttleMonkey from the it's-life-but-not-as-we-know-it dept.
shmG writes to share that recent imagery from Saturn's moon Enceladus indicate that it may be hospitable to life. "NASA said on Tuesday that a flyby of planet's Enceladus moon showed small jets of water spewing from the southern hemisphere, while infrared mapping of the surface revealed temperatures warmer than previously expected. 'The huge amount of heat pouring out of the tiger stripe fractures may be enough to melt the ice underground,' said John Spencer, a composite infrared spectrometer team member based at Southwest Research Institute in Boulder, Colo. 'Results like this make Enceladus one of the most exciting places we've found in the solar system.'"

Cryptome in Hot Water Again 241

Posted by ScuttleMonkey from the revel-in-the-bulls-eye dept.
garg0yle writes to tell us that Cryptome appears to have stepped in it again with a recent leaked document concerning Microsoft's "Global Criminal Compliance Handbook." "Microsoft has demanded that Cryptome take down the guide — on the grounds that it constitutes a 'copyrighted [work] published by Microsoft.' Yesterday, at 5pm, Cryptome editor John Young received a notice from his site’s host, Network Solutions, bearing a stiff ultimatum: citing the Digital Millennium Copyright Act (DMCA), Network Solutions told him that unless he takes the 'copyrighted material' down, they will 'disable [his] website' on Thursday, February 25, 2010. So far, Young refuses to budge." In a gesture of goodwill, Wikileaks has offered to host Cryptome via their twitter feed.

Copernicium Confirmed As Element 112 183

Posted by ScuttleMonkey from the cp-had-other-meanings dept.
Several sources are reporting that the International Union of Pure and Applied Chemistry has confirmed Copernicium as element 112 on the periodic table of elements with the symbol Cn. "The naming of the new element will be the culmination of a long, fraught journey involving fierce competition, dashed hopes, clever detective work and even a brush with scientific misconduct. With a nucleus containing 112 protons — 20 more than uranium, the heaviest of the naturally occurring elements — it will be the weightiest atom whose existence has been confirmed so far."

Use Open Source? Then You're a Pirate! 650

Posted by ScuttleMonkey from the and-proud-of-it dept.
superapecommando writes "There's a fantastic little story in the Guardian today that says a US lobby group is trying to get the US government to consider open source as the equivalent to piracy. The International Intellectual Property Alliance (IIPA), an umbrella group for American publishing, software, film, television and music associations, has asked the US Trade Representative (USTR) to consider countries like Indonesia, Brazil, and India for its 'Special 301 watchlist' because they encourage the use of open source software. A Special 301, according to Guardian's Bobbie Johnson is: 'a report that examines the "adequacy and effectiveness of intellectual property rights" around the planet — effectively the list of countries that the US government considers enemies of capitalism. It often gets wheeled out as a form of trading pressure — often around pharmaceuticals and counterfeited goods — to try and force governments to change their behaviors.'"

Latvian "Robin Hood" Hacker Leaks Bank Details 170

Posted by ScuttleMonkey from the too-many-hoods-in-the-forest dept.
eldavojohn writes "Move over Russell Crowe, an anonymous hacker in Latvia is being hailed as a real life modern Robin Hood. The hacker refers to himself as 'Neo,' claims allegiance with the Fourth Awakening People's Army, and is outing banks that are capitalizing off of the horrible economic status Latvia is currently suffering from. No word on how he is acquiring the information but it is slowly being leaked to TV sources via Twitter and the common people love him. The hacker is thought to be based in Britain but a TV reporter pointed out the fine line Neo is walking, 'On the one hand of course he has stolen confidential data ... and he actually has committed a crime. But at the same time there is value for the public in the sense that now a lot of information gets disclosed and the whole system maybe becomes a little more transparent.' An example of a juicy tidbit he revealed is that managers of a Latvian bank did not take the salary cuts they promised they would after the government bailed them out of economic trouble. You can imagine that taxpayers were upset and thankful they knew this information."

Space Junk Getting Worse 242

Posted by ScuttleMonkey from the time-for-a-doomsday-machine dept.
HockeyPuck writes "According to Space.com the amount of space junk is getting worse. 'A head-on collision was averted between a spent upper stage from a Chinese rocket and the European Space Agency's (ESA) huge Envisat Earth remote-sensing spacecraft. [...] But what if the two objects had tangled? Such a space collision would have caused mayhem in the heavens, adding clutter to an orbit altitude where there are big problems already, said Heiner Klinkrad, head of the European Space Agency's Space Debris Office in Darmstadt, Germany."

Hungarian Electric Car Splits Into Two Smaller Cars 147

Posted by ScuttleMonkey from the i-get-the-good-half-in-the-divorce dept.
Lanxon writes to mention that Antro, a Hungarian car manufacturer, is developing a new electric car that can split into two smaller cars. Antro plans to have it on the market by 2012. "The environmentally-conscious company started research back in 2002 and, with backing from various local sponsors, has invested 1.5 million euros in market research and development of a working prototype. The Antro Solo concept is a three-passenger car, with a hybrid drive and solar cells on its roof that the company says could generate enough electricity for up to 20km a day at city speeds. Futuristic looking in itself, the grander plan for the car is much more audacious: Antro intends to allow users to be able to connect two Antro Solos to form a six-passenger Antro Duo. Or perhaps more interesting still, owners of a Duo could split the car into two smaller Solos should Mum have different weekend plans to Dad. Or if they divorce."

Without a doubt, O’Reilly Media produces many of the finest information technology books on the market. Whether your need is beginner’s level introductions to information technologies or are a more advanced programmer in need of more complex and refined topics, O’Reilly has a book that can meet diverse needs of an audience often with vastly wide-ranging skill levels. One of their numerous series of books are the Nutshell series which their website describes as “topical quick-reference guides that document every nook and cranny of a topic or technology area . . . Designed to be daily companions, these books belong next to your keyboard, at the ready when you need a quick answer” (http://oreilly.com/store/series/nutshells.csp). Having used a couple of the Nutshell selections for a couple of years, I have to say that this description perfectly fits these books. They are not really a book you sit and read cover to cover.

The text contains twenty-six chapters covering all elements of C# 4.0. Notably, the book covers “features new to C# 4.0 and the associated Framework are flagged so that you can also use this book as a C# 3.0 reference” (Albahari & Albahari, 2010). This fourth edition of the book covers the significant new feature set being provided in C# 4.0 including dynamic binding, type variance with generic interfaces and delegates, optional parameters, named arguments, and COM interoperability improvements.

The first three chapters of the text concentrate purely on C# covering the basics of syntax, types, and variables. This front content finishes with advanced topics including unsafe code and preprocessor directives. New C# users should read all three of these chapters sequentially to gain the foundational understanding of the language before moving into the remaining chapters that cover the core .NET Framework including such topics as LINQ, XML, collections, I/O and networking, memory management, reflection, dynamic programming, attributes, security, concurrency, application domains, and native interoperability. For new C# programmers, chapters six and seven (Framework Fundamentals and Collections) should also be read sequentially as they are integral concepts. The text also contains three chapters covering LINQ that should be read sequentially (LINQ Queries, LINQ Operators, and LINQ to XML).

As I examined this book, I realized that it would serve as an excellent quick reference for developers of all levels. However, the book is targeted at intermediate to advanced audiences. For beginners who make the wise decision to include this book in their library, it will serve as an exceptionally useful complement to a tutorial-style instruction to programming in C# 3.0 or 4.0. It will also serve as an ideal companion to books focusing on applied technology such as WPF, ASP.NET, or WCF. In fact, this book should be a required supplementary text for beginning students in C# 3.0 or 4.0 programming classes.

To work the code examples (especially those specific to C# 4.0) you will need the following software tools and documentation:

        * C# 4.0 Compiler
        * Microsoft .NET Framework 4.0
        * Microsoft’s .NET documentation

All three of these items are available in Microsoft® Visual Studio 2010 which includes an express edition of Microsoft SQL Server®. SQL Server is required to run the LINQ to SQL and Entity Framework examples in the text, and includes IntelliSense. Currently, Visual Studio 2010 is available as a download from the Microsoft web page in a Release Candidate version (http://www.microsoft.com/visualstudio/en-us/products/2010/default.mspx). Official launch events for Visual Studio 2010 are scheduled for April 12th.

I would highly recommend this book to anyone interested in developing applications using C# 4.0. In fact, if you develop in C#, your library or bookshelf should not be missing this book. Clear concise examples, a great writing style, and wonderful diagrams of key concepts just add to the overall value of this book. Add to that the fact that you can use this book as a resource for C# 3.0 and it is a no brainer! Another excellent work from the O’Reilly team.
