This week I’m taking a few days off to ski, play with my dogs, visit with friends and family, and generally recharge my batteries. If you’re on vacation this week too, I hope that you’re having a great vacation. While I’m away I’m rerunning the most popular posts of the year. The selections are based on pageviews during 2012.

This morning I gave a short presentation on Android apps for education. The slides for that presentation are embedded below.
