The podcast I recorded on Thursday went off into the ozone layer somewhere. I cannot recover any of it. I prefer to blame it on Agent Smith, in his unending quest for Mr. Anderson.
However, you can get the drop on Agent Smith. He will be surprised to see you locking in on the Wednesday and Friday lecture podcasts for Section 0004. Do that with the PDF of the Thursday doc cam work, and you are ready to go.
But to throw off Agent Smith, I also made two mini-podcasts for iTunes U titled February 18, and they appear normal. Good. That is what we want him to think.
