New Coursera.org Class on Recommendation Systems
There’s a hot new class on Coursera.org this week from the University of Minnesota that starts September 3rd.  It’s all about the concepts and code behind recommendation systems just like the ones you see on Amazon and any other shopping or entertainment site.  The coolest part is that there’s two tracks: A track for Java developers, and a conceptual track for everyone else.

If you’ve tried and failed to thoroughly learn new programming concepts and languages through scattered tutorials and lesson sites like Codecademy and Treehouse, Coursera.org is a method you simply must try.  It’s methodical and keeps you on pace.

Samsung is All-In on Tizen

This recent interview with the Samsung co-CEO shows that Samsung and Intel have big plans for Tizen that are not limited to smartphones.  To outsiders, including some of the commenters, it seems that Samsung really wants to control the OS environment for their phones like Apple does.

Django and Play Framework Disclose Possible Vulnerabilities

I think it’s very responsible of the Django team to disclose the new BREACH attack discovered at the recent Black Hat Conference as a possible threat to Django sites.  This discovery was not made on a Django application yet the developers realize that it affects their system, and we should probably be aware that it may affect many other frameworks that have not made an announcement like this.

The Play framework also announced a security risk last week.  The vulnerability was found in Play’s session encoding.
