Hello there, and for those of you who have read my previous work, welcome back. Now, what is an Armstrong number: “In recreational number theory, a narcissistic number (also known as a pluperfect digital invariant (PPDI), an Armstrong number (after Michael F. Armstrong) or a plus perfect number) is a number that is the sum [...]

Hey there! Last time I spoke about how to add a bit of microservices style architecture flavor to your monolithic app and the benefits of doing it in such a way. Now I’m going to go through a concrete working example of a modularly built, ‘plug-in and play’, intuitive and reusable CSV importer. We’ll have [...]

Def: Microservices is a software development technique—a variant of the service-oriented architecture (SOA) architectural style that structures an application as a collection of loosely coupled services. – wikipedia “A collection on loosely coupled services”. Bit of a brain twist. Ok, loosely coupled we get from the get-go, it’s good software practice and design, but what [...]

Throughout my posts and in many many other articles, books, booklets and almost all (good) IT materials, you keep hearing the same over and over again, repeated almost like a mantra – “Find the abstraction and use it” – it’s good and all, but how you should go about it is almost always lacking in [...]

In the previous post “Organizing Your Code With The Help Of Modules” we created our very first outline of a module (though very basic) and mix it in a class via the include method (in this case we can refer to modules as mix-ins). If you haven’t noticed by now, the act of mixing in [...]

We know about classes and how they are an Object defined to “huddle up” like minded or similarly goal oriented objects (namely methods) and we know about class hierarchies, the perils that it imposes on our code through the thing called classical inheritance and how namespacing matters because the names we choose for our objects [...]

If you’re a hardcore software developer, a journeyman set on the noble path of software design and implementation, or you’ve just started out on this great journey, chances are you’ve hit a snag in the road while getting accustomed to continuous code implementation. And if you work as part of a team, where more people [...]

If you’ve been eying the opportunity to become a computer programmer for some time now, or even if you’ve just started venturing out onto this great and noble journey, chances are that you’ve hit yourself with this term quite a few times whether in books, booklets or even documentation sites, Classical inheritance has always been [...]

The Interface Segregation Principle states that no client should depend on methods that it does not use. In layman terms, what this principle iterates is that you only have to make public that which is essential to the core of your application. You can think of it like this: You’ve been hard at work all [...]
