Reaching me while I'm away

I will be gone from Friday (10/03) through Thursday (10/09). Notes:

• If the question you want to ask is something you could share with the rest of the class, with the possibility that someone from the class might have an answer, please post it as a comment to this blog post.
  
• I will be reachable via email, although since I will be traveling and at a conference, there will very likely be delays in replying.
• You may find me on skype (id: "atmajanardhan"). Again, I may not be available to take your call, or I may not be able to reply to IMs immediately. If there's sufficient demand, I can set aside a time that you can call me (let me know if you would like this.) As always, we can set up an appointment and talk.
