Welcome to Personal Puzzle!
Personal Puzzle, or PP, is a personal time management tool with an unique automatic scheduling feature, designed for freelance journalists, agile programmers or just about anyone with a need to plan their work day.
PP is developed by Johan Wallén and started out as a project during the programme “Agile Web Developer” at KYH Gothenburg. Since then the service has evolved and a closed beta version is imminent.
The core of PP is Ruby on Rails with a sprinkle of jQuery for some of the front-end features. Some of the ready made jQuery modules I've used are jQuery Countdown from Keith Wood (http://keith-wood.name/countdown.html) and Timepicker from Trent Richardson (https://github.com/trentrichardson/jQuery-Timepicker-Addon).
The calendar view in the schedule feature is made from the Railscasts episode 213 by Ryan Bates (http://railscasts.com/episodes/213-calendars-revised).
If you would like to know more about PP, have suggestions or want to take part in the development don't hesitate to contact me at firstname.lastname@example.org.
