Our First Entry!

by David Colarusso - April 11th, 2007

The First Annual Phylm Prize got its first entry today, and it’s from the people over at Science Made Fun, a student-run podcast over at the University of Manchester, England. One of the great joys of running this contest has been finding other people just as passionate about science education as myself. That being said, there’s still time to put together an entry. Check out the rules:

On Education Goes C-SPAN

by David Colarusso - April 8th, 2007

First, I apologize for what some readers may see as a “boring” diversion from our usual educational content, but to piggy-back on my last posting, check out this debate between Mark Cuban and Fred von Lohmann from the EFF. It’s a rather balanced look at some of the issues surrounding the Viacom Google lawsuit. However, I do see a problem with Cuban’s argument for filtering, namely that it doesn’t address the filtering of fair use content (see this post). Anywho, give it a look, and you decide.

Back in March when Viacom filed its $1 Billion lawsuit against Google I wrote a post expressing frustration with the media coverage. My contention was that the suit had the potential to chill fair use on the internet by making sites such as YouTube proxies for wealthy copyright holders. That is, if YouTube is denied safe harbor protection under the DMCA the burden of determining fair use effectively shifts from the courts to sites such as YouTube. Such a shift would force these sites to adopt overly cautious content polices or face costly litigation.
