The 2012 GNU Radio conference is over, but we're still getting all of the material together to publish. I should be putting up more of the presentations tonight and more as they come in (see the Abstracts page to download them).
What I really wanted to mention here was the GRCon12 Hackfest page. I'm trying to collect info here on what happened at the Hackfest and where people can go for more information (such as other web pages) and the code developed. So check it out, and hopefully it will be beneficial.
