FFTs Using AltiVec on Linux and Mac OS X
GregAllen writes "After searching for a good open-source AltiVec implementation of the Fast Fourier Transform (FFT), I have put together the AltiVec FFT page. It has all of the source, some benchmarks, and runs on Mac OS X or LinuxPPC. I even compared it to the venerable (but scalar) FFTW." -

Slashback: Texasocial, Networking, Attacks
Slashback this evening brings updates on social networks, Audioscrobbler, the Social Security-number security breach at the University of Texas at Austin, and more. Read on for the details.Why meet people in real life? Roland Piquepaille writes "I wrote [Saturday] a column about social-network mapping tools mentioned by Slashdot. Slashdot readers sent me many comments and e-mails about other visualization tools. Here are these new tools, in no particular order: email constellations, Apache Agora, NetVis Module, EtherApe, inGridX, NameBase's Proximity Search, Surf3D Pro and the dazzling KartOO. Finally, a reader talked about another kind of tools, the Visual Thesaurus. This web tool is not about social mapping, but it shows graphical connections between words. In this previous column, "The Visual Thesaurus: What Does it Show About Thanksgiving?," I already explored this very funny tool. Check this new story for more the details about all these tools."
Update: 03/19 00:34 GMT by T : Directly related: Josh Tyler writes "Related to a recent Slashdot posting on social networks is this paper on automatically discovering communities based on email data, just published by our group at HP Labs. We find that simple communication data is enough to identify communities, both formal and informal, and possibly even to identify the leaders of these groups."
Speaking of online community ... TGK writes "Audioscrobbler (which many of us visited the first time it was posted here) has a new site up, and most importantly, new plugins for XMMS and Winamp 3."
From the site, a capsule description of what Audioscrobbler does: "It grows to know what music you like by monitoring what songs you play on your computer. From this information you can discover other users that share some or all of your taste in music."
Feedback is always cool. An anonymous reader writes: "Sudhakar Govindavajhala, co-author of the paper referenced by the Saturday Slashdot article 'Using Memory Errors to Attack a Virtual Machine,' has responded to many of your [Slashdot readers'] questions and comments. His commentary is located at his Princeton CS website."
Another reason that Social Security isn't. GregAllen writes "Remember the recent case of SSN data theft at The University of Texas? A student has turned himself in. In his confession he says that he acted alone, and had no intention to disseminate the information. Maybe this will convince them to stop using SSNs for student IDs." Bonker also points out that "Salon is carrying an AP article that's a followup to the story a few days ago about the mass of Social Security Numbers stolen from University of Texas. Christopher Andrew Phillips is described as a 'fine young man who has never before been in trouble with the law'. Apparently he wrote a program 'to access a university Web site that tracks employees who attend training classes'. Whether or not this was done for illegitimate purposes remains to be seen. As a former UTA student, I'm glad my SSN is no longer in danger!"
What's the state of the device? An anonymous reader writes "N-Philes.com did another State of the GBA Industry Article and Roundtable. Here is the Industry Article, and here is the Roundtable"
Update: 03/19 00:34 GMT by T : And one more presroi writes "Just one week after even slashdot has noticed the new 2.2.24 linux kernel, Alan Cox has announced a new version due to a security issue found in 2.2 as well as in the 2.4 branch. I hope that we all were to lazy to upgrade from 2.2.X to .24 until now :)"

Using Technology to Find Missing Children?
GregAllen asks: "We live in a world where technology provides us global communication and instant gratification. The internet has made the world a much smaller place, and news travels at the speed of electrons. However, it's still pretty easy to hide. There is an epidemic in the U.S. -- the government estimates that there are 350,000 family kidnapping per year. You never think it will happen to you, but it did happen to me -- my ex-wife kidnapped our daughter and has been missing for almost 6 months. She's wanted by the FBI, but she hasn't been found. See the Find Sabrina website -- there's a $10K reward. When you are confronted with this situation, the world is an overwhelmingly large place. How would the alpha geeks at Slashdot use technology to locate someone that doesn't want to be found?" While putting up a website to assist in the search helps, are there other digital methods one can employ to assist in the search?
