Joomla is open source software under the GPL license. One of the benefits of open source software is that you can (and are allowed to) read and change the source code.

Therefore it's very easy to make small changes in Joomla's core code. But loosing those changes by just upgrading is even easier! 

In this presentation Peter Martin will show you how you can make changes in Joomla and 3rd party extensions without using core hacks:

  • what's a core hack
  • why you should not use core hacks
  • an example of a core hack
  • eight alternatives to change Joomla without using core hacks
  • how to fix (core) hacks (e.g. done by other people).
