Data Localization Library

A while ago I have written about the Localization Concern, and one of the topics that I have detailed there was Data Localization. By Data Localization we mean the cases when we need to store some text properties of some business entities in different languages. For example in an e-commerce

The Visitor Pattern - A Better Implementation

Even if it has been a while since my last post (I've been very busy lately with giving my training), one piece of feedback that I got back then, stuck into my head: You can make a better implementation of it. I remember somewhere a better implementation of

The Visitor Pattern

I have recently given my Design Patterns Explained training, and it felt like the Visitor Pattern discussion created the most aha moments in the audience. It seems that people have a hard time getting this pattern, so I thought to explain my understanding of it in the post. The Gang

My Wordpress to Ghost Journey

Migrating my blog from Wordpress.com to a self hosted blog using Ghost, was a lot of work. More then I have anticipated. If I look at my Trello board where I keep track of it, I see that I've started to work on this on January the

My Code Design Training Reshaped

It is already more than one year and a half since I started to give my Code Design training. I have developed this training as I say here, out of the desire to teach others the way I link the learnings from the best practices books to the code I

A New Look!

I've been quiet for a while. I didn't publish a new post in a few weeks. It wasn't because I got lazy or because I ran out of ideas or experiences worth sharing. I was really busy. As you probably know I've

Concurrent Unit Tests with Service Locator

My talk at Microsoft Summit created a nice discussion with some of the participants about writing isolated unit tests when using the Service Locator. It started from the part where I was showing how the AppBoot helps in dependencies management by enforcing consistency on how the Dependency Injection is done.

Speaker at Microsoft Summit

Last week I had the opportunity to speak for the first time at the Microsoft Summit. It was a nice and pleasant experience. I have talked about how we could achieve a high quality code design by enforcing consistency with the support of an Application Infrastructure in a large and

Crosscutting Concerns

The Crosscutting Concerns are the areas in which high-impact mistakes are most often made when designing an application. There are common causes that lead to this and there are common practices that can help to avoid such mistakes. In this post I will talk about the way I usually address

DRY vs Coupling

While reviewing my previous post another great discussion, which may arise from paying attention to your references, came to my mind: Don’t Repeat Yourself (DRY) vs Coupling. Each time you add a new reference it means that you want to call the code from the other assembly, therefore you

Using ReSharper for Assembly References Diagrams

A few posts back I talked about how we can use the assembly references to enforce consistency and separation of concerns (here and here are the old posts). I argue there that if we derive from the architecture the assemblies of our application, the kind of code (responsibility) each one

I've quit my job. Hire me!

Last Friday marked an important milestone for me – it was my last day working for ISDC. After 10 years with ISDC I have decided to put an end to my job there. I think it is a good moment in my life and in my career to try something else,

Localization Concern

Localization (also known as internationalization) is one of the concerns that is most of the times overlooked when we design an application. We almost never find it through the requirements, and if we do or if we ask about it, we usually postpone thinking about it and we underestimate the

Dependency Inversion and Assemblies References

In my last posts I have talked about using assembly references to preserve critical design aspects. In Enforce Consistency with Assemblies References I talk about how we can use references to outline the allowed dependencies in code and how to use a references diagram to discover code at wrong levels

Enforce Consistency with Assembly References

In this post I’ll describe some key aspects that I consider when designing the assemblies that build a system. When we structure our code into assemblies (generally named binaries, libraries or packages in other platforms than .NET) we are reasoning about three main things: * Deployment: different assemblies are deployed
