Apache's mod_rewrite provides methods to map values to attributes using the directive RewriteMap. One not so well known feature of mod_rewrite is to extend this functionality with internal functions, which can be defined in a seperate Apache module. mod_icpquery is an Apache-2.0/2.2 compatible module that extends mod_rewrite by internal RewriteMap functions. It sends out a request as a UDP query to a list of Unicast or multicast addresses. This query conforms to RFC 2186, also known as ICP, and can be handled by various HTTP-caching servers such as squid. A cache-server handling ICP should reply to an ICP query with an ICP response indicating if it holds the desired object in its cache or not. This information can be further processed by mod_rewrite using its superb regex rules.

Foxtract is a simple Outlook Express e-mail message extractor that works with corrupted data files. Instead of trying to rebuild or read from the tree structure that Outlook Express uses internally, it scans the whole data file to find all message segments, which it then uses to determine the head segment of a message and reconstruct it.

Thyrd is an experimental, reflective, visual programming language and environment. In Thyrd, both data and code are stored in cells situated in nested two-dimensional grids. All operations the user can perform to edit the structure are implemented as operators in the Thyrd language, thus a Thyrd program can inspect and modify itself or other programs in the same space. Thyrd belongs to the Forth family of languages. It most resembles Joy in that it uses quotation and combinators to implement iteration and recursion.
