Are you completely new to programming? Do you want to have fun learning to program?

"Squeak: Learn Programming with Robots" will teach you core programming concepts based on simple, visual problems that involve manipulation of robots, or "turtles." You will learn basic programming concepts like loops, abstractions, composition, and conditionals.

Each chapter is structured so that it can be turned into a one- or two-hour lab session. And while the structured content explains solid principles of object-oriented programming, you'll just have fun going through the sequence of easy examples with the turtle.

And be sure to check out BotsInc, the companion learning environment for this book.

This book constitutes the proceedings of the 19th International Conference on Software and Systems Reuse, ICSR 2020, held in Hammamet, Tunesia in December 2020. Due to COVID-19 pandemic the Conference was held virtually. The 16 full papers and 2 short papers included in this book were carefully reviewed and selected from 60 submissions. The papers were organized in topical sections named: modelling, reuse in practice, reengineering, recommendation, and empirical analysis.

Pharo is a clean, innovative, open-source, live-programming environment. Enterprise Pharo is the third volume of a series of book covering Pharo and its community. Whereas the first volume is intended for newcomers and the second volume covers deep topics of Pharo, this third volume covers libraries and frameworks for enterprises, and in particular those doing web development.
