For me 25 minutes are too short - you just get into something and it's time for the pause - especially for programming I think you need longer time periods. When doing the pomodoro technique I usually go for 45 minutes work units + 10 minutes break. That way you get longer focus and when you take a break it's a real break (so you can get out and walk for a bit for example).
