What do you use for backups of your Joomla web site? Until Joomla 1.6 (thanks Sam for adding this) there has been no backup routine built in to Joomla and yet backing up your website is the most important thing you should do.
No matter what your web host offers as a backup service this is your responsibility and only yours. Backups are too important to rely on anyone but yourself.
Since the beginning of Mambo "I want/need/demand ACL" (access control lists) must be one of the most common threads in the forums. But what do I/you mean by ACL and why is it just so dam hard to implement. (I assume it must be hard or it would have been done by now in the core)
One of the few pieces of code that I can claim any credit for is the ability to define a database prefix to all the tables in your site and this dates back to the early days of Mambo around the end of 2003. The reason it was frst introduced was to allow site owners to install multiple version of Mambo on a single mysql database.
But now it serves a second purpose in "helping" to protect your site from some of the more common security hacks.
