Jmx4Perl provides an alternate way of accessing Java JEE Server management interfaces that are based on JMX (Java Management Extensions). It is an agent-based approach where a small Web application deployed on the application server provides HTTP/JSON-based access to JMX MBeans registered within the application server. It is set up from a handful of Perl modules, which can be integrated seamlessly in your own programs. It also includes a Nagios plugin, check_jmx4perl, a jmx4perl command line tool for remote JMX queries and operations, and a readline-based JMX shell j4psh, with context sensitive command completion and syntax highlighting.
IPv6 CARE, "IPv6 Compliant Automatic Runtime Environment", provides an environment where applications instantly become IPv6-compliant ('patch' mode, see RFC6535). It can also generate a diagnosis about the IPv6 compliance of an application ('check' mode). It uses an LD_PRELOAD-based library injection technique.
n-Track Studio is an audio and MIDI multitrack recorder that turns your computer into a full-fledged recording studio. You can record and playback a virtually unlimited number of audio and MIDI tracks.
