Zak allows you to select one or more MP3 files and convert them into a single MP3, MP4, M4A, or M4B file. The primary use for Zak is audio books. Most audio books are distributed in several files, usually one per chapter. Converting these files into a single .m4b allows one to take advantage of the iPod's bookmarking features.
Zclean is a tool designed to remove zombie processes from systems where rebooting is not an option or where zombies spawn so quickly that rebooting becomes an issue itself. Zombie processes are unkillable (they've already finished execution) and therefore their removal requires manipulation of the kernel task list.
The zen Platform is a Java development environment for J2SE/J2EE. It eases and accelerates the Java application development by visual methods (RAD). Complete applications can be modelled in an intuitive fashion without the need for technical expertise. The complexity of Java and J2EE programming is tremendously hidden - reducing the learning curve for Java novices. Java experts are by no means restricted - they may apply their knowledge without limitations. Application flexibility is a core feature of the platform, which is delivered as an Eclipse plugin.
