Masqmail is an MTA (mail transport agent) for notebooks, workstations, home servers, and generally any host with no permanent network connection. It has special support for multiple transfer routes (e.g. to different mail providers). Address rewriting can be done in several ways. It is a slim replacement for full-blown MTAs such as sendmail, exim, qmail, or postfix and for the intended uses, configuration is much simpler.
Bidwell (named for Shelford Bidwell, the inventor of the first true fax machine way back in the late 1800s) is a set of Perl scripts that are designed to run as a cron job on a Unix-like system to download emails from a POP3 account and send their contents to a CUPS or lpr printer.
Event is a simple PHP-based software package for creating a simple Web page for upcoming events.

gpfcalc is a GTK+ front-end for pfcalc, a pipe friction calculator using the Darcy-Weisbach equation. It computes major, minor, and static losses for flow through pipes or ducts. Up to 1024 pipes or ducts can be defined by specifying hydraulic diameter, length, roughness, flow rate, temperature, and elevation change. Data can be saved in a comma separated values file (CSV) and imported in the spreadsheet program of your choice for further processing.
WorkingWiki is a software extension for MediaWiki that makes a wiki into a powerful environment for collaborating on publication-quality manuscripts and software projects. The WorkingWiki extension allows you to store "source files" in your wiki and develop, test, run, and publish them easily. Examples include a project of five LaTeX files and six EPS images that compile together into a single PDF file, or an R script that includes two other R source files and produces a CSV data file and several EPS figures. The WorkingWiki extension keeps track of when the source files have changed and when to redo the processing to update the output, and how to display the various file formats involved. The output files and images can be displayed in wiki pages along with the source code, and can be used as inputs to further computations.
