Programming Language

Snap! (formerly BYOB) is a visual, drag-and-drop programming language. It is an extended reimplementation of Scratch (a project of the Lifelong Kindergarten Group at the MIT Media Lab) that allows you to Build Your Own Blocks. It also features first class lists, first class procedures, and continuations. These added capabilities make it suitable for a serious introduction to computer science for high school or college students.


Textbook on Social Implications

In the non-programming part of our course we try to balance a fundamental optimism about the future of computer technology with an understanding of its limitations and potential for harm. Student readings are taken mainly from the excellent textbook Blown to Bits, which is available for free online download.
