Nicholas Negroponte and David Cavallo will be in Mumbai during the first week August, for the OLPC India Day. You can register for the event here.
David recently gave a talk about the education model behind the efforts of learning group at OLPC. The talk was recorded and can be viewed online at dailymotion.
Also, on a somewhat related note, Marvin Minsky has written a series of extremely interesting essays on learning, which are all available on the OLPC wiki.

• Flight back from Boston was not as bad as expected, since I was upgraded to business class :-).
• Had a horrible pain on my right index finger throughout the last week, and decided to stay away from computers and do some reading during the weekend. (ultimately I ended up sleeping much more that I really should)
• My old mobile phone (Motorola A780) was causing a lot of problems, and so I decided to replace it with a Nokia E71. It took me some time to get accustomed to the new UI, but apart from that, I am quite happy with it (love the keyboard and the thin design of the set).
• Managed to set up the NAS device that I had got in my home network. I was a bit worried about the device supporting only Samba, but it turned out that it runs some kind of embedded Linux set up, and enabling NFS was pretty easy.
