The SOLID Design Principles Deconstructed
SOFTWARE DESIGN & ARCHITECTURE

The SOLID principles are often presented as being core to good code design practice. Each of S, O, L, I and D do not, however, necessarily mean what programmers expect they mean or are taught. By understanding this range of beliefs we can learn more about practices for objects, components and interfaces than just S, O, L, I and D.

This talk reviews the SOLID principles and reveals contradictions and different interpretations. It is through paradoxes and surprises we often gain insights. We will leave SOLID slightly more fluid, but having learnt from them more than expected.

Pattern-Oriented Software Architecture
YOW! DEPTH FIRST WORKSHOP

Patterns offer a successful way of exploring, reasoning about, describing and proposing design ideas. There are many valuable aspects of pattern-based thinking that are overlooked in the common perception of design patterns. The original vision of patterns embodies a notion of incremental, feedback-based design – something that may come as a revelation to anyone who had mentally pigeonholed patterns together with heavier-weight design approaches. They are also somewhat broader in application than just OO framework design – something that may come as a surprise to anyone who had restricted their view of patterns to the handful of initial patterns documented by the Gang-of-Four.
