Some useful info on how to get started:

First things first. To understand what are you getting yourself into, here are the basics in a beatiful form.

Here are some other places worth checking:

• Codecademy has the basics and it’s a hands on learning environment without hours of boring videos.

• Khanacademy is similar to Codecademy, but with a wider range of courses, f.e physics, algebra and even human anatomy.

• Udacity has a nice Intro to CS course written in pythonthat can be challenging at times, but well worth the time and effort.

• And if that all wasn’t enough for you already or you know it then Harvard offers this for you.
