I’ve worked in IT since I graduated from college in 1992. When you’ve worked in technology that long, you tend to pick up a decent understanding on how it all works, where the weaknesses are, and when reliance on technology can be a mistake. A colleague at work shared this link of a presentation of No-Tech Hacking at DEF CON 15 last year and I think that anyone who works with computers and even those that don’t should take the time to watch it. It’ll give you a better understanding of the world as it really is and not just what you think it is.
The video is about an hour, but I think you’ll be sufficiently entertained and informed and will be appreciative of the time used to watch it.
Ah, yes, Johnny Long! I didn’t get to see his talk (busy, or in another area of the con at the time). Heard a lot of good stuff about his talk, tho, it had great reactions on the floor. AgentX (head of the speaker goons) has been going on about Johnny for a while– having watched this (finally) I see why.
