My presentation from SpringOne2 GX 2013 is now available online. It's hosted on InfoQ here.
This is similar to the Webinar that Stuart and I presented last month, but a bit longer (90 mins vs 60 mins).
If you're curious about one of the other sessions from SpringOne 2GX 2013, you can the list of currently available sessions online here.
or on the SpringSourceDev YouTube channel.
Don't see the session you want yet, hang in there. More sessions are being posted all the time.
