What I've loved most about developing an open-source project is the ideas that I get from others who look at the work and either A) validate ideas, B) suggest that something stinks, or C) call a royal WTF and force people (e.g., me) to explain ideas more fully. It's usually during these explanation...

Updated 2010.03.09 to reflect small modifications that were decided through subsequent discussions on S#arp forum and other DDD posts. Obviously, S#arp Architecture is the bee's knees when it comes to developing ASP.NET MVC applications. ;) But as a project evolves and gets larger, "out of the...

Preface (you know it’s good if there's a preface) In Architectural Paradigms of Robotic Control , a number of architectures were reviewed including deliberative, reactive, and hybrid architectures. Each of these exhibit a clean separation of concerns with layering and encapsulation of defined...

Recent conversation I had with someone the other day: Jack : Yes, but we can’t do it like that. The business does not work that way. Me : Why does it not work that way? Jack : It’s a fundamental aspect of the business. We can’t change that. Me : And I accept that, but have you thought...

Ultimately most complexity in software comes not from the requirements, the business logic, or even the underlying systems. Most complexity comes out of a poorly considered and managed architecture, and this is commonly seen in tightly coupled systems that rapidly degrade into Big Balls of Mud. The key...

Introducing a New Blog Series Rarely do I make new year's resolution. But I found myself pinky swearing myself a single resolution for this year: write a series of tractable posts concerning the development of software for robotics. Accordingly, I intend to introduce background, techniques, and examples...

Today a conversation sparked off on Twitter, started by Jimmy Bogard and Matt Hinze , and then carried on by myself and Glenn Block . The basic starting point was what the difference was between using an IoC container like Windsor or StructureMap and using MEF (the Managed Extensibility Framework ) I...

(It looks like Kevin Pang and I must have seen the same vision this weekend or had a close encounter flashback as he's concurrently putting together a great series on Dependency Injection for Dummies ...be sure to check out his posts for another take on this subject!) S imply put, dependency injection...

From the beginning of my current project we have been working under some horrible constraints, many imposed by legacy systems, many by late decisions that would have speeded things immensely if made earlier, and many imposed by decisions that are outside of my control. This lead us early on to make decisions...

In my previous post I described the problems with trying to integrate your organisation at the database level , and the fallacies surrounding the idea of the One True Authority Database. I also alluded to this being a problem with services too. When you try to create a monolithic and authoritarian database...

There are many ways you can commit commercial suicide, but there is possibly no slower and more agonising death than that produced by attempting that great architectural objective, the single authoritative database to which all applications talk. The theory is good, if we have a single database then...

Recently I joined a new project, and within reason, and excluding some legacy systems we have to talk to, we have the “luxury” of an almost greenfield project. Probably as greenfield as you realistically get anyway. I was brought in partially as a good old fashioned coder (the project needed...

I sat down yesterday for a really interesting interview with a potential client. We discussed a variety of things, but one thing that stood out for me was a question around which message bus I would use and why. Apparently there had been some discussions already, and the application being developed might...
