I had the pleasure of attending DerbyCon 4.0 (Family Rootz) this past Friday and Saturday and can tell you that if you haven't already attended yourself, plan to do so next year. Aside from the smaller and more encompassing "family" feel, an intentional and protected approach strongly advocated for by @HackingDave and the great @DerbyCon team, you'll also be contributing to Hackers For Charity (HFC). For those of you who couldn't attend but are interested in some of the outstanding content, Adrian Crenshaw (@irongeek_adc) and his team always shoot video of each presentation. For DerbyCon 4.0 they've posted the videos to the Irongeek site here.  

There are so many great talks to choose from but I'll share a few that really resonated with me given current interest or focus areas:

Attacking Microsoft Kerberos: Kicking the Guard Dog of Hades - Tim Medin
Abusing Active Directory in Post-Exploitation â?? Carlos Perez
Ball and Chain (A New Paradigm in Stored Password Security) â?? Benjamin Donnelly and Tim Tomes
Third Party Code: FIX ALL THE THINGS â?? Kymberlee Price and Jake Kouns

You should also, in the simple name of humanity, watch Johnny Long's keynote, Hackers saving the world from the zombie apocalypse.

Great conference, great people, great presentations; take the time to watch as many of the videos as possible, and see if you can get a ticket next year when DerbyCon comes around again.
