Udacity - Intro to Computer Science - Build a Search Engine [repost]

In this introduction to computer programming course, you?''ll learn and practice key computer science concepts by building your own versions of popular web applications. You?''ll learn Python, a powerful, easy-to-learn, and widely used programming language, and you?''ll explore computer science basics, as you build your own search engine and social network. Why Take This Course? You?''ll learn the programming language Python, and you?''ll explore foundational concepts in computer science. Most importantly, you?''ll start thinking like a software engineer by solving interesting problems (how to build a web crawler or a social network) using computer programming.

This course is a first step into the world of computer science, and whether you want to become a software engineer, or collaborate with software engineers, this course is for you. You?''ll be prepared for intermediate-level computer science classes when you?''ve mastered the concepts covered in this course.
Build a Search Engine:
Throughout this course, you?''ll build a search engine by learning about and producing key search engine components including a crawler, an index and a page rank algorithm. As you build these pieces, you?''ll be learning about and practicing computer science skills that will ready you for intermediate level computer science courses.
Build a Social Network:
At the end of the course we will give you a set of relationships (i.e. strings of phrases like ?'?Dave likes Andy, Kathleen and Kristy?'?) and you will use your new computer science skills to organize these relationships into a social network. With your new social network, you can explore relationships and gain insight into how you fit into your own social networks.
