Submission + - Checkers solved, unbeatable database created (nature.com)

Submitted by
tgeller
tgeller writes: "My story in Nature announced that a team of computer scientists at the University of Alberta has solved checkers. From the game's 500 billion billion positions (5 * 10^20), "Chinook" has determined which 100,000 billion (10^14) are needed for their proof, and run through all relevant decision trees. They've set up a site where you can see the proof, traverse the logic, and play their unbeatable automaton. Congratulations to Dr. Schaeffer and his crew!"

Submission + - Study: Scientists not very Religious

Submitted by Davin
Davin writes: Study finds that top scientists are not very religious, but that is not because they studied science.
http://www.buffalo.edu/news/8732
"The first systematic analysis in decades to examine the religious beliefs and practices of elite academics in the sciences supports the notion that science professors at top universities are less religious than the general population, but attributes this to a number of variables that have little to do with their study of science."

Submission + - All Humans Evolved from a Single Origin in Africa (sciencedaily.com)

Submitted by
Invisible Pink Unicorn
Invisible Pink Unicorn writes: "Researchers at the University of Cambridge have combined studies of global human genetic variations with skull measurements worldwide to conclusively show the validity of the single origin hypothesis. The alternative hypothesis contended that different populations independently evolved from Homo erectus to Home sapiens in different areas. The lead researcher explains, 'The origin of anatomically modern humans has been the focus of much heated debate. Our genetic research shows the further modern humans have migrated from Africa, the more genetic diversity has been lost within a population. However, some have used skull data to argue that modern humans originated in multiple spots around the world. We have combined our genetic data with new measurements of a large sample of skulls to show definitively that modern humans originated from a single area in Sub-saharan Africa.' The article abstract is available from Nature."

Submission + - Instrumented GIMP to Identify Usability Flaws

Submitted by Mike
Mike writes: New users of the GIMP often become frustrated at the application's unwieldy user interface. For this reason Prof. Michael Terry and a group of researchers at the University of Waterloo have created ingimp, an modified version of the GIMP that collects real-time usability data. Terry recently gave a lecture about ingimp and the data it collects. During each session, ingimp records events such as document creation, window manipulation, and tool use. A log of these events is sent to the ingimp server for analysis. The project hopes to answer questions such as "What is the typical monitor resolution of a GIMP user?" and "Is GIMP used primarily for photo editing or drawing?" Answers to these questions will help the GIMP developers find and fix GIMP's usability problems. For more information about ingimp, visit the project's web site.

Text Compressor 1% Away From AI Threshold 442

Posted by kdawson from the second-hutter-prize dept.
Baldrson writes "Alexander Ratushnyak compressed the first 100,000,000 bytes of Wikipedia to a record-small 16,481,655 bytes (including decompression program), thereby not only winning the second payout of The Hutter Prize for Compression of Human Knowledge, but also bringing text compression within 1% of the threshold for artificial intelligence. Achieving 1.319 bits per character, this makes the next winner of the Hutter Prize likely to reach the threshold of human performance (between 0.6 and 1.3 bits per character) estimated by the founder of information theory, Claude Shannon and confirmed by Cover and King in 1978 using text prediction gambling. When the Hutter Prize started, less than a year ago, the best performance was 1.466 bits per character. Alexander Ratushnyak's open-sourced GPL program is called paq8hp12 [rar file]."

JagsLive writes: "FoxNews reports, http://www.foxnews.com/story/0,2933,288665,00.html " Geller's tireless attempts to silence his detractors have extended to the popular video-sharing site YouTube , landing him squarely in the center of a raging digital-age debate over controlling copyrights amid the massive volume of video and music clips flowing freely online. "All it takes is a single e-mail to completely censor someone on the Internet," said Jason Schultz, a lawyer for the online civil rights group Electronic Frontier Foundation, which is suing Geller over an unflattering clip posted on YouTube for which he claimed a copyright ownership.

Submission + - Making the GIMP Suck Less (uwaterloo.ca) 1

Submitted by GIMPFan
GIMPFan writes: Most people who have ever tried the GIMP know that its UI leaves much to be desired. Thankfully, at least one person is doing something about it. Usability expert Michael Terry has created an instrumented version of the GIMP called ingimp. The key feature of ingimp is that it collects usability data in order to determine how people are using (or struggling to use) the GIMP. This data is made available on the ingimp site so that researchers can study usability in the GIMP, which can hopefully lead to improved usability of the GIMP.

Terry also recently gave a talk on his project. In his talk, he emphasizes that the user's privacy is a key consideration of the project. He notes that contrary to most usage-collecting applications, ingimp is open-source and that the collected data is available to anyone. He also notes that Inkscape is also very interested in creating an instrumented version.

Submission + - ingimp - Datamining OSS to collect usability data. (uwaterloo.ca)

Submitted by
NaleagDeco
NaleagDeco writes: "In a talk at the University of Waterloo, Professor Michael Terry discusses the use of data mining (in a customized version of The Gimp) in order to discover and analyse real-world usability data. He touches on encouraging users to participate, privacy concerns, as well as common user categories that the software is currently able to sift out.

What is the typical monitor resolution of a GIMP user? How many monitors do they have? What size images do they work on? How many layers are in their images? The answers to these questions are generally unknown: no means currently exist for open source applications to collect usage data. In this talk, Professor Michael Terry will present ingimp, a version of GIMP that has been instrumented to automatically collect usage data from real-world users. Prof. Terry will discuss ingimp's design, the type of data we collect, how we make the data available on the web, and initial results that begin to answer the motivating questions. ingimp can be found at http://www.ingimp.org/"

Canada's Wayne Crookes Sues the Net 200

Posted by kdawson from the shotgun-doesn't-begin-to-cover-it dept.
newtley writes "Wayne Crookes, the Green Party of Canada's ex-financier, is in effect trying to sue the Internet. He's going after the Wikipedia, Google, and openpolitics.ca (run up by federal Green Party activist Michael Pilling) claiming he's suffered, 'an immense amount of frustration and emotional distress' over postings. Some 15 others may also have been targeted. "Mr. Crookes seems to be 'trying to unwrite history,' Pilling says. 'He was a central figure in the growth of the Green Party. His actions were highly controversial and if we have freedom of speech in this country, people should be allowed to talk about them.'" Newtley adds in a posting submitted 121 minutes later: "Literally 15 minutes after I posted [the foregoing], there was a knock on my door. It was a writ server telling me I, too, have been named in a lawsuit launched by Wayne Crookes..."

Laptops And Flat Panels Now Vulnerable to Van Eck Methods 144

Posted by Zonk from the i-seee-you dept.
An anonymous reader writes "Using radio to eavesdrop on CRTs has been around since the 80s, but Cambridge University researchers have now shown that laptops and flat-panel displays are vulnerable too. Using basic radio equipment and an FPGA board totaling less than $2,000 it was possible for researchers to read text from a laptop three offices away. 'Kuhn also mentioned that one laptop was vulnerable because it had metal hinges that carried the signal of the display cable. I asked if you could alter a device to make it easier to spy on. "There are a lot of innocuous modifications you can make to maximize the chance of getting a good signal," he told me. For example, adding small pieces of wire or cable to a display could make a big difference.'"

Submission + - AMD reports $611 million loss

Submitted by mpfife
mpfife writes: Toms hardware reports that "Declining microprocessor sales as well as dropping average selling prices for its microprocessors have pushed AMD deeper into the red. The company reported a net loss of $611 million on revenues of $1.233 billion, which is more than 20% below the guidance the company expected at the end of Q4 2006. The loss includes charges related to the ATI acquisition in the amount of $113 million, but is mainly a result of the increasing competition with Intel in the microprocessor market."
