GIJ is a Java bytecode interpreter, not limited to interpreting bytecode. It includes a class loader which can dynamically load shared objects, so it is possible to give it the name of a class which has been compiled and put into a shared library on the class path.

The mpm-itk module, although not technically a Multi-Processing Module (MPM) (although it used to be) enhances the classical "prefork" module (that is, without threads), in such a way that it allows you to constrain each individual vhost to a particular system user and group. This allows you to run several different web sites on a single server without worrying that they will be able to read each others' files. mpm-itk is largely independent of e.g. what scripting technology is in use on your server; in particular, it does not require you to run your scripts as CGI to get the extra security benefit.

The DragonFly Mail Agent is a small Mail Transport Agent (MTA), designed for home and office use. It accepts mails from local Mail User Agents (MUA) and delivers them either to local mailboxes or remote SMTP servers. Remote delivery includes support for features such as TLS/SSL and SMTP authentication.

systemd-bootchart is a tool, usually run at system startup, that collects the CPU load, disk load, memory usage, as well as per-process information from a running system. Collected results are output as an SVG graph. Normally, systemd-bootchart is invoked by the kernel by passing init=/lib/systemd/systemd-bootchart on the kernel command line. systemd-bootchart will then fork the real init off to resume normal system startup, while monitoring and logging startup information in the background.

The ownCloudSync system lets you always have your latest files wherever you are. Just specify one or more folders on the local machine to and a server to synchronize to. You can configure more computers to synchronize to the same server and any change to the files on one computer will silently and reliably flow across to every other.
