Why Programmers Should Challenge the Stakeholders

Have you ever worked on a state of the art programming project? And then a new requirement arrives, it's implemented and suddenly you're working on a legacy project?

Migrate to Ghost 1.x on Azure

You might remember that I am running this blog on Ghost self hosted on Azure. I wrote about how I've migrated from Wordpress in an older post. Now, I migrated to Ghost 1.x, and in the process I configured a better dev environment for my theme and auto deployment to an App Service from GitHub

Decide between In-Process or Inter-Process Communication at Deploy Time - Part 3

This is the last post from the series on how we could implement a design that allows to decide only at deploy time how two services communicate: in process if they are deployed on the same server or inter-process if they are on different machines. The first post shows where

Decide between In-Process or Inter-Process Communication at Deploy Time - Part 2

This post continues the previous by giving an example on how we could implement a design that allows to decide only at deploy time how services communicate: in process if they are deployed on the same server or inter-process if they are on different machines. If you haven't

Decide between In-Process or Inter-Process Communication at Deploy Time

After a long vacation in October last year, followed by some intensive work at MIRA and InfiniSwiss, now I can make some time to share some more design ideas that I have implemented along the years. I thought to resume blogging with showing how we could design for something which

AppBoot Library

AppBoot is a generic .NET application bootstrapper, we at iQuarc, have put on GitHub a while ago. It started few years back when we were about to begin developing a large enterprise application. Back then, we wanted to use the Unity Container for dependency injection, but we liked the way

Row Level Authorization with Entity Framework

A few posts back I wrote about the benefits of having a well encapsulated data access implementation. One of the benefits outlined there was the advantage it may bring when we need to implement row-level authorization at the data access level. In this post, I will detail this implementation on

Data Isolation and Sharing in a Multitenant System - Part 3

This is the last part of the "Data Isolation and Sharing in a Multitenant System" article, which is also a continuation of my post that outlines the benefits of a well encapsulated data access. In this post, we'll look in detail at the implementation of the

Data Isolation and Sharing in a Multitenant System - Part 2

This post is the second part of the article that shows how a well encapsulated data access implementation can play a key role in implementing a multitenant application. It is also a continuation of my post that outlines the additional benefits such a data access implementation may bring, multitenancy being

Comments Opened!

When I've migrated my blog to Ghost (My Wordpress to Ghost Journey) I've left a few things not done. Quite a few actually. Integrating a comments service was one of them. Last year, I didn't have much time for the blog, and the little

Data Isolation and Sharing in a Multitenant System - Part 1

In the previous post I've shown few of the additional benefits a well encapsulated data access implementation brings. Implementing multitenancy is one of them. This article continues the previous, picks up the multitenancy context from there, and shows how we can address one of the most important design

Benefits of Data Access Encapsulation

We all know that achieving a good Separation of Concerns is good, because it increases the maintainability and it reduces the cost of changing our code. This pays off big time in long running projects, with large code bases where changing code is a big part of the coding activity

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
