Understanding the SOLID Principles

This article is about the SOLID principles and it is called “Understanding the SOLID Principles”, this article show us this principles in detail and well this principles are focused into allowing developers implement the best practices in the creation of objects and classes according to the situation that they have, SOLID is an acronym that means the five principles of object oriented programming and design and these principles are…

Single Responsibility, focuses on the creation and verification of classes that should have exactly one responsibility which makes the classes more clean and we should maintain an standard development methodology. Then, Open/Closed Principle where the classes should have one characteristic when inheriting because they should be extendable preferred to modifiable and a class have to be constructed in order to be flexible and adaptable for the conditions that exist in the particular situation.

The third principle is called Liskov Substitution and this one thinks that we should avoid inheritance when is possible, providing flexibility, the fourth is called Interface Segregation Principle and it tells us that smaller interfaces are better and finally we have Dependency Inversion which wants to write code that refers to interfaces instead of code that refers to actual classes and we avoid dependency to make everything more concrete.

These are the best practices and reading about them I truly believe that if we used this practices we would improve our ability a lot.

Ethical Reflection on Ready Player One

This last entry will be focusing on answering some questions about the book Ready Player One, I really enjoyed the reading and also the movie, perhaps some things changed in the movie but overall the idea behind both the book and movie are the same and well the questions that I chose to answer are these ones: 1.      Do you find any interesting resemblances between the dystopic “real world” presented in “Ready Player One” and those presented in other works of fiction such as “Nineteen Eighty-Four”, “The Hunger Games”, “The Matrix”, “Soylent Green”, etc. My answer in this case is that a constant in many dystopian future works of art is first the problem with the energy, in the book they mention that the last crisis that they had was the energetic I believe and a similar idea can be found into the matrix were humans are used as electricity because of the lack of energy I believe, also as always mankind is destroying all their resources and in movies like Blade...

Microservices

This reading was about Microservices and well microservices is a very simple thing, there are many benefits into using microservices, turning complicated systems or applications into simple services that can me modified without disturbing the architecture of whatever you are building, this means in more specific words that there is modularity into the microservices architecture and this means that the services which we build using this architecture are faster as well as easier to develop, understand an implement. In a big scale development microservices allow us to deploy changes to specific parts of any development without the need of re deploying all the development, just deploying the module in which we are working or that we are going to modify and this reduces complexity as well as time spent into fixing or improving things that our services may use, each microservice provides a firm module boundary allowing different services to be written in different programming languages ...

Is design dead?

This reading is extremely interesting, it is about planned and evolutionary design which are two different styles of software development and well planned design basically is a way of development that allows us to have a process that maintains the entropy in a great state while evolutionary design is related to Extreme Programming, which is based into quick iterations and decisions without the need or thought of analysis and basically it is more trial and error than careful planning, it actually is the way in which most people program nowadays. Extreme programming uses different kinds of patterns in different ways and these patterns are what makes XP useful, these patterns are useful because they let us have cleaner code in any project, they are easy to understand and there is also the simplification that using a pattern brings into our work, using the new methodologies like xp and complementing these methodologies with tools like design patterns allows us to grow as developers an...
