GNU parallel is a shell tool for executing jobs in parallel locally or using remote computers. A job is typically a single command or a small script that has to be run for each of the lines in the input. The typical input is a list of files, a list of hosts, a list of users, a list of URLs, or a list of tables. If you use xargs today you will find GNU parallel very easy to use, as GNU parallel is written to have the same options as xargs. If you write loops in shell, you will find GNU parallel may be able to replace most of the loops and make them run faster by running several jobs in parallel. GNU parallel makes sure output from the commands is the same output as you would get had you run the commands sequentially. This makes it possible to use output from GNU parallel as input for other programs.
The BID software was designed to apply business rules to your email traffic. Business information can come from business applications, monitoring applications, or normal users requesting or providing data. The goal of the BID tool is to automate the dispatching of this information and to join a business-case with a responsible receiver. A receiver can be a human being or another BID server customized for a special business-case. The BID server was designed as a generic server using plugins to serve specific business-rules.

OpenFWTK is an application proxy toolkit which inherits the ideology of TIS fwtk and maintains API backwards compatibility. The design goal is to make it simple yet powerful; no performance hacks are allowed in the code and library dependencies are reduced to a minimum. It is a true application layer filter. It features unified pluggable content inspection for the most frequently used protocols, NAC (Network Admission Control), and the ability to define fine-grained Internet access policy based on browser identification.
Rxpd plugin for XChat is a plugin for the XChat IRC client which lets users filter the incoming conversation with the RegexPolicyDaemon. This is used to ignore spam, trolls, and other abusive content (at the user's option). People can publish their ignore rules and then filter or merge published rules from friends into their own rules, thus providing a distributed peer to peer system.
