Selfie: Computer Science for Everyone
Last updated on 2017-02-24
About the Book
Computer science is a mystery to so many and yet more and more people use computers every day in one form or another. There are increasingly many people with all kinds of backgrounds other than computer science that even develop software, sometimes without even knowing it. At colleges and universities around the world there is hardly anyone left who is not confronted with the machine and its code. While a book about computer science for everyone may sound appealing it actually requires serious commitment to understand the material even though we tried very hard to simplify everything as much as possible. The reason is that computers and software are so expressive that it is unlikely that any other computational machine in the future will be more expressive. Anything that can be computed can be computed now, if you have enough time. Selfie is an educational software system that has grown out of many years of teaching undergraduate and graduate classes in computer science. The key observation is that understanding the meaning of software and ultimately the behavior of a computer can only be achieved by understanding how software translates all the way down to the bits of the machine. Selfie shows how to do that. This may sound scary but can actually be done in a systematic fashion using only basic principles.
Disclaimer: This is work in progress. Only two chapters are done. There is also the draft of a third chapter included in this version. More chapters exist in draft form but will take more time to be done. For more information including source code of selfie and this book refer to selfie.cs.uni-salzburg.at
