I get emails from O'Reilly about different webcasts. Sometimes they are pretty interesting. Today I registered for one about mobile app development. Apparently it is in some way connected to OSCON. Which is cool. Anyway, here is the funny part, after I registered it gave me a link to test my system. I did - and as you can see I failed the operating system test because I'm not running Windows or OS X. I did the registration and ran the test on my Fedora 19 machine.
