Visualization of Egyptian Revolution On Twitter 53

Posted by CmdrTaco from the revolution-will-not-be-televised dept.
An anonymous reader writes "A visualization of the network of retweets with the hashtag #jan25 at February 11 2011, at the time of the announcement of Mubarak's resignation, is available. The data was collected using Gephi connected to the Twitter Streaming API, converting the users and retweets to nodes and edges in a dynamic network. Though the data represents only approximately 10% of the retweets, it's interesting to see the large flow of interconnected retweets in just one hour." I've attached the video if you want to watch it.

Microsoft Family Safety Filter Blocks Google 332

mike.rimov writes "I saw that part of the brand new Windows Live package is the Family Safety Filter, so I decided to give it a spin. Turned it on, set it to 'basic filtering' (their lowest level), and went to Google ... oops, it blocks Google! So I logged into the settings and added Google as an exception. Google still wouldn't come up. Just in case, I turned off the family filter: voila, Google. As we all know, 'Don't be evil' is not part of Microsoft's motto! Oh yeah — and with the filter on, Microsoft's own search engine, live.com comes up." Anomaly?

Facebook Users Get Lower Grades In College 284

Posted by timothy from the but-doodlers-do-fine dept.
Hugh Pickens writes "According to a survey of college students Facebook users have lower overall grades than non-users. The study by Aryn Karpinski, an education researcher at Ohio State University, found that Facebook user GPAs are in the 3.0 to 3.5 range on average, compared to 3.5 to 4.0 for non-users and that Facebook users also studied anywhere from one to five hours per week, compared to non-users who studied 11 to 15 or more hours per week. Karpinski emphasized that correlation does not equal causation and that the grades association could be caused by something else. 'I'm just saying that there's some kind of relationship there, and there's many third variables that need to be studied.' One hypothesis is that students who spend more time enjoying themselves rather than studying might tend to latch onto the nearest distraction, such as Facebook or that students who use the social networking site might also spend more time on other non-studying activities such as sports or music. 'It may be that if it wasn't for Facebook, some students would still find other ways to avoid studying, and would still get lower grades. But perhaps the lower GPAs could actually be because students are spending too much time socializing online.' As for herself, Karpinski said she doesn't have a Facebook account, although the co-author of the study does. 'For me, I think Facebook is a huge distraction.'"
