The Austin Hackers Association is a loose group of hackers and security professionals in the Austin, Texas area. We have monthly meetings that offer short 5-10 minute presentations about a large range of topics including computer security, physical security, pentesting, electronics, programming, and general nerd/geekery.
There is no formal membership for AHA! However, participation is mandatory:
NOTE: By “Academy” we mean we don’t actually teach you anything. We are not a school.
 NOTE ADDENDUM: The preceding note does not mean we are not affiliated with the University of China in Austin, Texas. That is still a topic of debate.
