Each week I will record a short audio file that give some information about things happening in the course for that week.
These will be very short (~5 minutes or less) and designed to give a quick overview and reminders.
There is also an RSS file at http://info1112.bobkummerfeld.name/rss.xml so you can subscribe to the podcast in a feed reader or podcast app. Some students might find this a convenient way to get updates about the course.
