Mike and Andrew Weber are my good friends over at http://www.beginlinux.com. In this video, Mike gives a wonderful training session on configuring UFW firewalls in Linux. The training session was done during a public Google Hangout.
Google Hangout is part of Google Plus. A Hangout is a shared space where people can talk and collaborate via webcam, text chat, voice, and shared desktop screens. It is an absolutely amazing experience, and it reflects what the future of computing will be. If you have not tried Google Plus, it is light years ahead of Facebook.
I sat through Mike and Andrew's recent Google Hangout where Like gave training on the vi text editor. He is a gifted teacher. I learned more in the 20 minute session than I have learned about text editors in 6 years of using Linux. I encourage you to subscribe to the entire series on Youtube here: http://www.youtube.com/user/beginusinglinux?feature=watch
Okay, without further ado, here is the video. Enjoy it, if you enjoy it as much as I did, share it with your friends.
