1. The document discusses the history and principles of extreme programming (XP), an agile software development methodology. It covers topics like iterative development, simple design, testing, refactoring, pair programming, collective ownership, and regular communication.
2. Design patterns are introduced as techniques to solve common software design problems. The document outlines important design patterns from the Gang of Four book and discusses applying patterns in an XP context.
3. The document recommends several books and resources for learning more about XP, design patterns, agile methodologies, software craftsmanship, and related topics. It emphasizes learning through collaboration and apprenticeship over formal instruction.

1. The document discusses various software design patterns such as Strategy, Template Method, Component Configurator, and how they can be applied to system design problems.
2. Design patterns like Strategy and Template Method are used to solve problems related to sorting algorithms and database queries by separating the algorithm from its implementation.
3. The Component Configurator pattern allows components to be configured at runtime through an XML configuration file, improving flexibility and reducing the need to recompile when configurations change.
This document discusses the first five principles of object oriented design (SOLID): single responsibility principle, open/closed principle, Liskov substitution principle, interface segregation principle, and dependency inversion principle. It provides examples of how to apply each principle, such as separating classes with single responsibilities and using abstraction and inheritance to allow extending software while preventing modifications. The principles aim to create high cohesion, flexibility, and substitutability within object oriented systems.
The SOLID Principles Illustrated by Design PatternsHayim Makabee
The goal of the SOLID design principles is to improve the Separation of Concerns, through weaker Coupling and stronger Cohesion. The main consequence should be software systems that are easier to maintain and to extend. However the definition of the SOLID principles is quite abstract, and some developers find it difficult to apply them in practice. In my talk I will show how well-known Design Patterns illustrate the application of the SOLID principles, and also show examples of how to follow these principles to Refactor and improve existing designs.
About the speaker:
Hayim Makabee was born in Rio de Janeiro. He immigrated to Israel in 1992 and completed his M.Sc. studies on Computer Sciences at the Technion. Since then he worked for several hi-tech companies, including also some start-ups. Currently he is a co-founder of the International Association of Software Architects (IASA) in Israel. Hayim is the author of a book about Object-Oriented Programming and has published papers in the fields of Software Engineering, Distributed Systems and Genetic Algorithms.
The document discusses software design principles and patterns, including the SOLID principles, design patterns like factory method and abstract factory, code smells like duplicated code and feature envy, and refactoring techniques to address smells like extracting classes and collapsing hierarchies. It provides examples of applying principles and patterns to real code and suggests design is key to creating high-quality, maintainable software.
