High Cohesion, Loose Coupling

We are living in a time where businesses and the people running them often change their mind. I won’t be gong into details of why is that so, let’s just say it is a given, and let’s say they are right. It gives them the competitive edge when they are flexible. It is on us to provide that. We are witnessing a high demand for a maintainable software, software that can change easily over time, and where the most of the effort measured in time and people’s work on projects happens after the initial release…long after the initial release if you’re happy. Needless to say, if we want to software to succeed in the long run, we must set our own mindset towards a way, that will provide the businesses their much needed value in that long run.

I know the following is a bold statement, but, you cannot say this enough so that it doesn’t become true.

There is no silver bullet in software development.

The only thing that separates the good software from the bad one is the value of the software for the business at that particular point in time. In order to prolong the value of the software for a long period of time you have to make it respond easier to change.

How you achieve that is a completely different matter. It borderlines with art and being able to predict the future. But, the good thing is that there are a few guidelines that you can follow that can help you out.

Here, I try to put some light on two of those: cohesion and coupling….Read on…

Value and Reference

Whatever you do in the .NET framework deals either with value or reference types, yet, there seems to be a great deal of confusion in many discussions with fellow developers and on online forums and QA sites about where the actual variables reside. It is so basic yet a cause of so many misconceptions. For example one of them is that value types reside on the stack and that the reference objects reside on the heap. We will try to break up some of those misunderstandings by carefully examining and explaining what really happens(with the current implementation of the .NET runtime, which at the time of writing is .NET 4.5.1)

Before we dig deeper into this issue I just want to say that this is by no means a comprehensive guide to how types are handled in the .NET framework. It would take a whole book on that. I’m simply trying to create a nice picture and get a few things clear as a general concept by working the foundations and trying to create a picture of what is one possibility of what happens behind the scenes down at the deepest level.

The Story of the Modern Day Developer

Software Developer, a “Programmer” even an “Engineer” or a “Craftsman“, although there are substantial differences between these according to some people, when we say any of them we mean one thing….an organism that transforms coffee into code 🙂 so I will continue with the term “Developer” and I wouldn’t like to go into that discussion right now because it can turn out to become a book.

We have come a long way from being the “basement” nerds, that nobody wants to talk to, to the modern day mixed media served image of super-rich-enterpreneur-programmer(which is sadly just a few lucky ones). So where is the truth? What are we, where are we? How do we manage to form a picture of ourselves and waht we want to accomplish in todays diversity of technologies and approaches to software development?

I know it maybe not much. But, having been there for quite a while both as amateur since I was a little kid typing random programs in Basic on my Commodore 64 back in the 90’s, then professionally since 2005, all the way until today. I will try to share my view and experiences of what I consider the most important values of a modern day developer by answering dozen of questions.

So, here we go.
