Universities Advance High-Speed Trans-Atlantic Network
Campus Technology (06/21/11) Dian Schaffhauser
The University of Indiana is working on two projects aimed at linking U.S.-based universities with research institutions in Europe and Asia. The American Connects to Europe Project will use Hibernia Atlantic's transatlantic fiber-optic network to connect participating universities and labs with European counterparts. The project will receive funding from the U.S. National Science Foundation and GEANT, a multi-domain topology that includes 34 European countries connecting 30 million researchers. The infrastructure is supplied by the Delivery of Advanced Network Technology to Europe. Indiana University also has received funding to develop the TransPAC3 project, which aims to connect with Asian researchers under the International Research Network Connection program. "It facilitates sharing of expensive resources, such as telescopes and microscopes, and also physical locations," says Indiana University's James Williams. "If we're going to study the effect of climate change on the withdrawal of glaciers in the Himalayas, we need some way to figure out how to get our measurement instruments to the Himalayas."

Free App Protects Facebook Accounts From Hackers
UCR News (CA) (06/20/11) Sean Nealon
University of California, Riverside (UCR) researchers have developed MyPageKeeper.org, a free Facebook application that detects spam and malware posted on users' walls and news feeds. MyPageKeeper was developed in response to a recent surge of malicious activity on Facebook. The application works by continuously scanning wall posts, news feeds, and links posted by friends of participating users. As soon as malware, spam, or other undesirable material is detected, MyPageKeeper notifies the user and enables them to remove the malicious content from their profile. MyPageKeeper was developed by UCR students Md Sazzadur Rahman and Ting-Kai Huang, as well as UCR professors Michalis Faloutsos and Harsha Madhyastha. Rahman says that Facebook "provides a fertile ground to spread malware, since users trust links and posts that are seemingly from their friends. Hackers have realized this, and they have started using it to distribute malware and conduct identity theft." Faloutsos says that Web security is following the same trajectory as desktop security as more activities move to the Internet. "People are educated about email spam," Faloutsos says. "But, now there is an implicit trust, almost validation, when someone sees a post from a friend on Facebook."

'Hadoop Alternative' to Be Open Sourced
IDG News Service (06/15/11) Chris Kanaracus
LexisNexis will open source its HPCC Systems supercomputing platform and offer developers an alternative to the Hadoop framework for large-scale data processing. The platform operates on clusters of commodity hardware and is comprised of components oriented around LexisNexis' Enterprise Control Language. The company says that data extraction, transformation, and loading tasks are managed by a component dubbed Thor, while a third system called Roxie delivers "highly scalable, high-performance online query processing and data warehouse capabilities." The system is capable of analyzing petabyte-sized data volumes "significantly faster and more accurately than current technology systems," scaling up to thousands of nodes, according to LexisNexis. Both a community edition and a commercial enterprise edition of HPCC Systems will be released by LexisNexis. HPCC Systems will initially be offered as a virtual machine for testing by the developer community, with full binaries and the source code to be released some weeks later. The community version will be issued under the GNU Affero GPL v3 license, while new code contributed by LexisNexis and community members will go to the open source edition first, according to LexisNexis.
