Architecture is about intent, we have made it about frameworks and details, Robert C. Martin, “Uncle Bob”, stated earlier at this year’s DDD Exchange Day in London. Robert refers to a book by Ivar Jacobson from 1992 and brings the original thoughts about use cases into architecture models, e.g. Hexagonal architecture and Clean architecture to improve these models.
The Open-Closed Principle, OCP, part of the object-orientation SOLID principles, was recently criticised by Jon Skeet and Robert Ashton who both believes the principle is doing more harm than good.

Dependency Injection has become a much more accepted and accessible approach in recent years, driven by many factors including increased popularity in SOA, TDD, and many other factors.

In his new post, Jason Bloomberg introduces two types of services – Entities and Tasks, and explains the role each type of services plays in building SOA systems.
Gilad Bracha reopens an old debate; can a language be OO and rely on primitive types? He advances an argument that Java fails to be truly OO because "Java’s original sin was not being a pure object oriented language - a language where everything is an object."
