This site is powered with a homemade PHP software. It does not require SQL or any other fancy or expensive features.
The software was originally written by me for Autosound Technical Magazine for their site. I modified the software heavily for my own use adding weblog functionality, improved photo album etc. Table based layout was also changed to support stylesheets. At least the html source code looks nice now :-)
Administration of this blog is horrible, so I suggest you check out some commericialized pieces of software instead of this. In addition this software is not written for heavy usage. The features are added using the infamous "no worries" attitude. For example the sidebars would really require caching in real use.
