libposix is an impementation of the core functionality of all Unix systems. It is a full, cross-platform implementation of the POSIX 2008 standard. It is meant to replace existing implementations of a Unix system's core libraries. It is an exact implementation of POSIX 2008 and nothing else (no extensions, no previous POSIX versions). However, it works well with possible extensions to the core system functionallity (for example, GNU or BSD).

Differences to libevent include higher speed, simpler design, more features, less memory usage, embedability, and no arbitrary limits. libev supports epoll, kqueue, Solaris event ports, poll, and select.
Most Java/Swing frameworks strive to be comprehensive. By contrast, JComponentBreadboard aims to support the smallest collection of JComponents and the simplest facilities for composing them into forms, just sufficient to specify the majority of Java/Swing forms. It includes the main capabilities such as simplified layout management, data binding, data validation, but so streamlined that there's much less to think about, and only a 63KB JAR to download.
Waffle is a Java Web framework that allows for POJO-based actions. Dependency injection support is built in. Waffle does not require any custom XML configuration files, nor does it have a proprietary templating language. Web applications built on Waffle are easier to write and test than those built on other frameworks.
