If you not only want to know what ÔÇťObject-Oriented ProgrammingÔÇŁ means, but are also interested in its origins and what it can achieve, start here, at the very beginning. Let Francesco take you on a journey. Learn about the essence of good objects and write good stories that those objects can tell.

Course Programme

Why Turtle Graphics?

Turtle graphics is an educational programming tool that has been around since the 1960s. The concept was developed by Seymour Papert, a computer scientist and pioneer in the field of artificial intelligence.

Papert's idea was to create a programming language that would allow children to explore mathematical and geometric concepts in a visual and intuitive way. The result was Logo, a simple programming language that could be used to control a virtual turtle. By issuing commands to the turtle, such as "move forward," "turn left," and "pen up," children could create complex patterns and shapes on the screen. Logo quickly became popular in schools and universities as a way to teach children about computer programming and geometry.

In this course, you will learn how to build a turtle graphics application from scratch and apply good design practices, including software design patterns, to create a well-structured, maintainable, and extensible software system. By building a turtle graphics application, you will gain experience with concepts such as state management, geometric transformations, and user input handling. You'll also leverage advanced design patterns like the Model-View-Controller (MVC), Interpreter, State, Command, and other patterns to create a flexible and scalable architecture, giving you a solid foundation in software design.

Your learning goals

Studying HotDraw can offer a number of benefits for individuals interested in software design, including:

  • Combine multiple design patterns: Learn how to apply design patterns such as the Model-View-Controller (MVC), Interpreter, State, and Command to create a flexible and scalable architecture.
  • Develop a programming language: Learn how to create a simple programming language for the turtle graphics application to automate repetitive tasks and enable new possibilities.
  • Gain experience with user input handling: Develop skills in handling user input through the graphical user interface to provide a better user experience.
  • Familiarize with geometric transformations: Learn how to manipulate the turtle's movement and orientation on the canvas, providing a foundation for advanced 2D graphics.
  • Practice state management: Learn how to manage application state to create complex programs with multiple features while maintaining a clear separation of concerns.

About the Trainer

Francesco Cirillo

Francesco Cirillo has worked at the forefront of the software industry for more than 30 years. In a career spanning startups, corporations and freelance consulting, he has mentored thousands of professionals, developers, managers and software teams.

In the 1990s he worked as a Senior Consultant and Mentor for Sun Microsystem, expert in Software Architectures and Software Development Processes and Java and Object-Oriented Evangelist.

Francesco is one of the pioneers of Agile Methods. He started working on XP and TDD in 1999. He was chosen by Kent Beck to develop the XP community in Europe and as reviewer of the second edition of the book Extreme Programming Explained. In 2000 he created XPLabs, the first company in Europe to offer comprehensive services on XP: software development, training and consulting.

In 2007 he created the Anti-IF Campaign to raise awareness in the international community of software developers to apply good design principles to grow software in a sustainable way.

Since 2008 Francesco stopped actively working on Agile Methods and started to develop RRP, a new method of software development. In 2013 he created Cirillo Consulting based in Berlin to offer professional training and consulting on productivity and software development.

Francesco invented the Pomodoro® Technique, a renowned time-management method used by millions of people all over the world, while being a university student looking for a way to get more done in less time.
