I am a programmer that is getting to know the Magento platform. I want to dig in and begin programming extensions and seeing what I can accomplish.
However for some reason I am having a hard time finding a good tutorial or general guide on how to create extensions and interact with the platform.
I see the Magento API, but that looks like it is mainly for webservices and communication with Magento from the outside world.
Can anyone point me toward a good book or tutorial that can help me get a handle of how to program extensions?
