One of the biggest obstacles when getting started with Xdebug was that I had a hard time finding good instructions on how to set it up on Mac OS X (I finally got rid of windows, yeah !). The only good resource I found was stored in Googles cache (wasn't live anymore) and had instructions on how to manually build xdebug from source.

His is a four step process of installing XDebug support on his MAMP setup - including a few configuration directives you'll need to apply to get XDebug support included.

ActiveState is pleased to announce the creation of the Open Komodo Project, a new initiative to create an open source platform and promote open standards. The Open Komodo Project will support the open web and web standards, fill a need for developer tools in the open web technology stack, and drive further innovation for Komodo IDE and Komodo Edit.

They want to create a framework for development that integrates with other software (like Firefox) and makes development of both simple applications and complex, rich applications simple.
