Logfilter is a tool for performing ad hoc analysis on Apache log files. Logfilter is especially useful when you wish to find records matching very specific criteria, since you can specify exactly which fields to match. The tool also plays well in a Unix environment by accepting input either through files or via stdin.
Jacman is a GUI frontend to ArchLinux's "pacman" package management system. It provides an attractive interface to the majority of key features of Pacman, including installing, removing, and updating packages. It also includes "rollback" functionality to return back to an older version if necessary.
Evo Class Index is an annotation processor that at compile-time generates an index of classes implementing a given interface, classes annotated by given annotation, or placed in a common package. Its small run-time performance impact makes it an interesting alternative to any annotation scanning library like Reflections or Scannotations. The generated indexes are compatible with the ServiceLoader framework, so you will never need to create the files in META-INF/services by hand.
