I've participated in this the last couple years. It is really well done. The puzzles get progressively harder as the month goes on. I usually try to use a language im interested in but don't have a lot of experience with, but thats even more of a challenge and generally by the 15th or 20th im struggling to find enough time to complete the puzzles, but I try to go back and finish everything eventually. Always learn something new; theyre generally problems different from what I work on day to day.
