The XE Toolkit is a multi-platform, network-aware, secure performance monitoring solution for tactical analysis of enterprise computing systems. It uses Java and provides an API in the form of Java jar files that contain the programmatic interfaces needed to craft custom tools. It remains a toolkit, perhaps more complex than the SE Toolkit, but also far more versatile.
JPerf is a perfect hash function generator for Java. The principle of perfect hashing is to reduce the average constant overhead of a hash table by precomputing a hash function which is optimal for the key set. Other advantages include a reduction in memory usage. Finding such a hash function is hard, especially in the general case. These run-time savings come at a cost of increased map creation time. JPerf can create a perfect hash function for a given set of keys and values.
The Epeios MIDI to XML converter makes it possible to convert binary MIDI files to a format that allows them to be handled effectively with tools like CVS. If you put, using your favorite MIDI sequencer, the CVS '$Id$' tag (or other CVS tags) in the comment tag of the MIDI file, the changes made to this tag by CVS are propagated into the MIDI file.
The 'expp' tool (the Epeios XML preprocessor) reads an XML file to transform it to another XML file. It simplifies the writing of XML files by allowing the handling of macros, the definition and testing of variables, the inclusion of files, and more. This is done by writing, directly in the source XML file, predefined tags owned by a given namespace, tags which are then recognized and handled by the 'expp' tool. The tool is also available as a Java native component.
Mediastreamer is a portable C library that allows you to create and run audio and video streams. It is designed for any kind of voice over IP applications. It features RTP connectivity, audio codecs (Speex, iLBC, G711, GSM, and AMR), video codecs (MPEG4, H263, H264, and Theora), sound card I/O, wav file streaming, webcam video capture, echo-cancellation, conferencing, parametric equalization, and various other utilities. It has a modular design that makes it extensible through plugins. This is the media-streaming component of linphone, a GPL SIP video phone.
