When you have the opportunity to take a break from being in the office, it is almost necessary to stay up to date (if not catch up) on events that have have been occurring in the information technology / security fields.
I have had the opportunity to take a holiday and have been working through my backed up books, RSS feeds and forums. One of these projects or to-do items is to finish a course on www.codeschool.com . When I was an undergraduate, python was taught as a replacement for the intro level Java course, which I think was a great option. CodeSchool offers a great refresher on the subject as I am currently working through the python track.
I would strongly recommend codeschool to those that need a quick interactive refresher or to those looking to pick up a new language.
