it conversations
Since I've been working from home full time, I've really gotten addicted to IT Conversations. The talks make really good background for coding. Some are boring and I generally pick and choose ones that interest me. Here are a few I've liked lately:
R0ml Lefkowitz, Chief Technical Architect, AT&T Wireless
Jonathan Schwartz, President, Sun Microsystems
Philip Greenspun, Software Engineering
Update:
Clay Shirky, Ontology is Overrated (forgot this one)
