Some links of great presentations

Finally after a long postponement, I saw the presentation How to design an API by Joshua Bloch. I want to share a link where you can see the video and presentation. Just click here. Also while googling him, I found that he is one of the top 40 software people in the world. If you are interested, here is the list. 

InfoQ is a great site with exceptional presentation. One of the latest addition is Neal Gafter's presentation. I hope to see that soon.
