Top 3 Tech Podcasts I listen

Sunday, January 6th, 2008

This Week in Tech: the grandmother of all tech podcast. Leo and John C make a good pair. It’s nice to hear (always) opposing views. The recent episodes with Jason Brooklyn Gangtsa-style Calacanis were full of insight. He is a great guest.

Not an alternative source of energy

Tuesday, November 20th, 2007

With the high price of oil, it is important to distinguish the alternative sources of energy available to us. Contrary to popular beliefs, not all alternative sources of energy are good. Solar energy on roof tops is great. Wind mills are good but may be an eyesore. Biodiesel/biofuel is bad I think. Using agriculture [...]
