- Emphasis on creativity provides open-ended programming for media creation like creating visual or audio collages that apply the material to relevant subject matter.
Use of Python provides an easy to learn and use programming language and more applicable to the world of Media Computation.
- REVISED! Bugs from the third edition have been fixed.
The Web as a Data Source teaches how to read from files and discusses how to write programs to directly read Web pages and distill information from there for use in other calculations, other Web pages, etc.
Real CS1 content meets the ACM/IEEE Computing Curriculum 2001 guidelines for a CS1 course, including coverage of procedural, object-oriented, and functional programming approaches, even though the book has been used most with non-CS majors.
