I swam.

 Yesterday, Feb. 17, I worked in my office to develop some web systems with Ruby on Rails. For acquiring knowledge to make development more efficient, I read the Japanese edition of Rails Guide. Yesterday I read the section 6.2 about Active Record Associations. I was surprised at powerfulness of Active Record.
 After work, I went to the sports gym and swam about an hour.
