Paul is well known as the author of Vixie cron and DNS BIND server daemon. Corey has made contributions to many open source projects including Mozilla and the Gentoo Linux.

Download of The Day: CRON-O-Meter Open Source Dieting Software

CRON-O-Meter is free, open source, and cross-platform (Windows, Linux and Mac OS X) dieting software written in Java. It is a fully featured nutrition and biomarker tracking tool. Designed for practitioners of Caloric Restriction (CRON) Diets.

From the project site:

CR (Calorie Reduced) diets require a lot of information to perform optimally. In order to restrict caloric intake, but remain healthy, users of the diet must track their vitamin, mineral, and protein intakes with great care.

We aim to provide a complete solution to the CR dieter. Current open-source diet-tracking applications fall short in some vital respects. Either they are not detailed enough, or they suffer from critical usability flaws. We believe that a diet tracker must be effortless to operate for the activity for which it will be used most of the time, keeping track of the foods eaten in a particular meal.

To this end, we are developing CRON-O-Meter, an application that will take into account good usability design and dense functionality. It will provide diet advice, track consumption and exercise, and generally assist in all aspects of a CR diet.
