PyApache
I make considerable use of Python both as a system scripting facility and
as a cgi-bin facility
The Apache webserver which serves all of our website is able not just to serve files from the filesystem but also can execute programs and serve the results. Server-side executables are generally termed "cgi-bin" facilities, after the name of the special directory in which they are usually located.
Apache can be configured not just to execute external programs but also to load an enabling module for one or more of the popular scripting languages modules such as Perl, PHP or Python.
Loading a module to enable "native execution" of a scripting language dramatically speeds up the execution of the script.
For various reasons, I favour the PyApache module over the now-standard ModPython module. This section of the Bel EPA site provides downloadable resources for users of PyApache and keeps local copies of the latest versions of the module.
This is also good for Bel's search engine positioning, there are all sorts of external links pointing in to Bel's PyApache pages, just the thing that the search engines are tuned to recognise and value. I think it's a good example of the "what goes around, comes around" principle, otherwise available as a research paper titled: "Maximising outcome through reciprocal value assessment."
