Expose is a PHP template engine. It supports server and client-sided caching, a plugin system (to simplify common tasks like inserting a date picker) and internationalization (to write templates in multiple languages using external translation files). Unlike most template engines, Expose's template script language is based on PHP itself, which means you don't have to learn a new syntax. You can use most of the PHP language elements and functions in the way with which you're familiar.

HEBCI is a technique that allows a Web form handler to transparently detect the character set with which its data was encoded. By using carefully-chosen character references, the browser's encoding can be inferred. Thus, it is possible to guarantee that data is in a standard encoding without relying on (often unreliable) Web server/browser encoding interactions.
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.
