For those of you who are interested in technical-related careers, IT Conversations really is a hidden gem out there. They often have talks on IT trends such as offshoring, open source, and fascinating subjects in general such as Malcolm Galdwell's talk on Human Nature. IT Conversations rates their talks which I find to be very helpful (I filter out anything less than 3 stars). Additionally, you can have them downloaded straight to your iPod--also known as podcasting--which I often do since I like to listen to talks while I drive to work or while travelling.
I just heard a talk that Paul Graham gave recently who is famous for the millions he made off Yahoo's stock and for essays he publishes online on his website. Here is an excerpt from the description:
"Paul Graham, popular author and Lisp programmer, discusses what business can learn from open source. According to him, it's not about Linux or Firefox, but the forces that produced them. He delves into the reasons why open source is able to produce better software, why traditional workplaces are actually harmful to productivity and the reason why professionalism is overrated."
