The highlight of the discussions was the Shmoo Group. The Shmoo Group is known throughout the hacker community as a leader, and is respected by everyone. The line to get into the talk went from the front to the back of the hotel, so I decided to watch it from my room - sitting on a nice couch instead of packed in the tent with standing room only.
There were a lot of very technical discussions which again mystified me, but there was also the Wi-Fi pistol (Figure 3) which can detect signals miles away.

This device follows in the footsteps of last year's gadget from the Flexilis group, the Bluetooth sniper rifle, which they used to wreak havoc on Bluetooth devices at last year's DEFCON. The WiFi pistol matched this feat with its power to detect any access points within a few miles and then close in on them. The gun is not only powerful, but an amazing device to look at.
Some other topics Shmoos covered were encryption algorithms and flaws in different security programs. Even more impressive than the talk, however, was the respect the group received and how they covered a wide area of research and demonstrated their ability to be creative through hacking.
