Radiant is an open source content management system built with Ruby on Rails. It is built for small developer teams other than the end-users as it requires programming knowledge.

With a very simple interface, Radiant offers flexibility when creating the design & content. 3 parts: pages, snippets (like PHP includes) and layouts create the core of the system.

It offers a flexible site structure where pages can be arranged according to any hierarcy.

Radiant has a custom template language named Radius (similar to HTML) which can be used inside pages, layouts to include content from other pages or display content conditionally & more. It also has an intelligent caching mechanism which helps serving pages faster while ensuring the content is up-to-date.

PHP Speedy is a a PHP script which increases the loading times of web pages.

PHP Speedy automatically joins all the appropriate files together and compresses them which decreases the amount of requests made to the server & sizes of the files. Result is a dramatic decrease in the loading speeds.

The script can be used in most of the PHP enabled websites.

Installation of this PHP script can be done automatically or manually. After the installation PHP Speedy code must be inserted at the top of the website’s main content generating file (index.php in most cases). There is already a how-to for Wordpress too.
