Environment
The software used here at PsyPhi.net is all Open-Source. That is software which is free to use, distribute and modify under the terms of the GPL software license.
The MySQL database, together with the scripting abilities of Perl within mod_perl and Apache provide a superb environment for "killer" web-based applications.
Apache
Apache is a free web-server. That is the fundamental software which drives websites.
The Apache web-server software in fact drives over 60% of the web. Its popularity stems from the fact that it provides an unparalleled environment for production-quality websites.
Stability and flexibility are paramount when it comes to providing a service and Apache delivers.

Gimp
Gimp is a free image creation and manipulation tool. It combines the power and flexibility of Photoshop with the simplicity of Paintshop Pro.

Linux
Linux is a free operating system. As with commercial operating systems like Microsoft Windows or MacOS, Linux provides the interface between the computer hardware and the applications which users see.
Here at PsyPhi.net, Linux has been used since it became a viable alternative to commercial operating systems in 1996. It provides excellent flexibility, stability and performance for minimum cost.

mod_perl
mod_perl is a free Apache plugin. It provides a fast, efficient Perl interpreter actually built into the web-server.
Scripts and modules are precompiled by mod_perl and remain resident inside the web-server process resulting in speed and performance increases.
The efficiencies of some other restrictive bottlenecks such as pipes for database access also undergo enhancement from within mod_perl.

MySQL
MySQL is a free database system. Like the Apache web-server, the stability of MySQL is an absolute necessity for providing a high-quality service.
[Go there]
Perl
Perl is a free scripting language. It is especially powerful for processing data. It is fast and efficient, especially when combined with the Apache mod_perl plugin.
Perl provides easy to use interfaces to most other applications through the use of other (mostly free) modules. For example, database access functions are available through the Perl DBI module.
Using Perl allows for truly rapid development and deployment of websites.
