In this post, I describe how to move a Drupal based website from a single site installation to a multi-site installation. The instructions are centred on Debian/Ubuntu, but should be easy to adapt to other setups.
We run monit on a number of clients' Linux systems to ensure that all their server daemons keep running as necessary. In this post I describe an issue that arises due to conflicting default SSL/TLS protocols in Zarafa and monit, along with a monit configuration change to work around the issue.
A short script to toggle compositing on or off for XFCE Window Manager (XFWM).
