Using MediaWiki’s web based installation wizard while various authorization and other security mechanisms are in place throughout Apache’s configuration contexts can lead to problems which are very hard to troubleshoot. This post outlines some things you should avoid while installing MediaWiki.
This post describes how I addressed an issue with the content type of the robots.txt file of my Redmine installation at CodeTRAX, so that the indexing bots could properly evaluate it and thus index only those sections of the web site that are meant to be indexed.
It’s been a while since WordPress implemented revisions for posts and pages. Being able to revert a post or page to a previous state is a useful feature. However, I recently realized that WP creates a revision of the content every time it is saved, but there is no upper limit for the number of…
The first time I used WordPress back in September 2005 I considered it to be the content publishing platform of choice as far as a personal or business website was concerned. It was easy to set up and publish content and, also, easy to customize, even with ugly hacks.
I needed to make some changes to the website layout this afternoon, so I turned off WP-Super-Cache for a while. As you can clearly see in the following graph the CPU time consumed by php-cgi processes increased by 2-4 times when caching was turned off between 14:00-17:00.

This is a project I had been thinking about for the last 2 years as a solution for source-code management at CodeTRAX.org, but I never really started development. The initial plan included support (repository creation only) for the most…
Permanently removing deleted posts and topics in bbPress can be cumbersome. bbPress does not provide a decent way to completely remove deleted content from the database. I am not sure why… In my case, these posts mostly contain spam and there is absolutely no reason to keep them in the database any more. As it…
