Giada is a minimal, hardcore audio tool for DJs and live performers. Just pick your sample, drop it in any channel, and start the show by using this tiny piece of software as a loop machine, drum machine, sequencer, live sampler, or effect (VST) host. Giada aims to be a compact and portable virtual device for production use and live sets.
tcpdump prints a description of the contents of packets on a network interface which match a given boolean expression. It can also be run with the -w flag, which causes it to save the packet data to a file for later analysis, and/or with the -r flag, which causes it to read from a saved packet file rather than to read packets from a network interface. In all cases, only packets which match the expression will be processed by tcpdump. tcpdump logs more than just TCP, IP, or ethernet packets, but has a whole suite of decoders, including ones for USB.

Griffon is dekstop application development platform for the JVM. Inspired by Grails, it leverages the Groovy language and concepts like convention over configuration. The Swing toolkit is the default UI toolkit of choice however others may be used, principaly SWT and JavaFX. Developers may use a combination of the Groovy and Java as well as other JVM languages such as Scala, Clojure, Mirah, and Jython. It encourages the use of the MVC pattern and follows in the spirit of the Swing Application Framework (JSR 296) by defining a simple yet powerful application life cycle and event publishing mechanism.
