Drupal
If you want to automate the maintenance of your Drupal sites the best tool is drush. It allows you to maintain modules, run sql queries, clear caches, show logs, run cron, and perform unit tests. Nothing more to say, but I only recently found this tool and if you love the command-line like I do this works like a charm.

Brilliant Gallery
Drupal has over 4,000 add-on modules available and it is easy to get lost in choosing which to download.
One of the first things you look for when you build a new website like Code Trials is a cool looking image or gallery module. The best and most flexible I have found is the Brilliant Gallery. You can see an example here. Not only does this module look sharp, it is very flexible and the creator of the module: Tomáš J. Fülöpp is continuing to develop the module with wonderful new features.
I tried a number of different modules before finding this one and now this is the only one I use. Thanks Tomáš for the module!
Wow what a truly brilliant system Drupal is. Dries Buytaert, creator of Drupal, is a rock star for sure. I was able to knock this site out in a few hours thanks to Drupal. I have spent the last fifteen years building custom web development solutions and over the last twelve months I have seriously questioned why am I bothering when systems like Drupal are available.
Luckily there are reasons why Drupal does not work for us, primarily to do with mass customization and new application creation. However, if you are looking for a solution that covers all the basics and more, you’d be hard pressed to find a better system than Drupal. I question what I’m doing every time I use a Drupal site.
Thanks Dries your masterful code is appreciated here in Austin, Texas!
