T here exist some principles that make a procedure easier to perform, with this resource, it is viable to create clean products. In programming, exist something called SOLID principles that ensure quality and good performance while developing code, this acronym SOLID are the 5 widely accepted principles: S - S ingle Responsibility Principle A class should have exactly one responsibility. O - O pen/Closed Principle A class or a function should be open for extension but closed for modification. L - L isvok Substitution Principle Keep the relationship between classes and functions. I – I nterface Segregation Principle Avoiding interfaces that overloads classes with responsibilities that this classes don’t actually need. D – D ependency Inversion Principle “ Depend upon abstractions not upon concretions.” By understanding each one of this SOLID Principles, we could manage to create good code, and by good code I mean cleaner code that is maint

How far technology can go? It is an often question everyone ask, including such philosophical questions about we humans and our creations, just like our Frankenstein Monster, our creation could bring chaos to ourselves. We have the power to create and the limit of our creation could be bypass by that same creation. This movie called War Games, bring this topic and it is an actual matter, and now even more because now a days technology had reached tremendous power and capacity that is very impressive, some tasks that we humans cannot do, or maybe as fast, are done by our own creation. Just like the arguments of the Android David in the movies Prometheus and Alien Covenant, David reached a conscious level that defined him to be as he was and committing every action during the movie. It is that self evolution that keeps growing and it hasn’t the same limits as human interpretation has. Another example is this classic movie 2001 A Space Odyssey, from S. Kubrik, HAL 9 000, who has e

Software Craftsmanship can be seen as a methodology in order to create good software, which has strong key elements that established the measures and techniques to create professional software development. It is the strong and complete philosophy to practice and helping others learn this craft, and as the Software Craftsmanship Manifesto ( http://manifesto.softwarecraftsmanship.org/ ) established some “rules” that completes this task. Such as the work on software that has to be performed to a well-crafted software, the response to change and the steadily adding value, the relationship between individuals and interactions and through the community of professionals developing software and finally customer collaboration with also productive partnership. Software Craftsmanship has a strong structure that can help the software industry in order to produce software quality, this philosophy can be applied in other topics. During the podcast with Bob Martin, or well known as “Uncle Bo

Design is one of the key elements to make a project succeed, design is a good practice in everything, sometimes without design, goals are unreachable. In software development is sometimes kind of difficult to reach a good design, there are a lot of reasons behind it, one of them is the lack of standards that are now even used during the design process. Methodologies gain an important role in software design, but depends on how the methodology is implemented or ever if this methodology is worth enough to the requirements of the whole project. Modulation comes in hand while talking about design implementation, dividing the big problem into little parts is easier to manage, process and maintain. Sometimes during implementation of certain project phases, comes changes, and this changes could determine the project success, it comes to my mind the warship Vasa, which suffered a lot of changes during the elaboration and planning process that made the ship finally sink. Some problems pres

“We have met the enemy, and he is us.” Human beings are symbolic animals, we give an interpretation of our observation, recognizing everything as a symbol, creating concepts in order to give meaning to our existence. At first creating certain laws that rule our reality because each concept and law we created makes sense in our own interpretation, from that we continued creating more and more concepts and laws which are based in our preview interpretation, being the architecture of our whole understanding. Society has become the architect of every brick that constructs reality, and the architect is the one who makes the important decisions in order to continue the construction. With one building which has an established basis, and with the expansion during the course of time, it is difficult or even impossible to make changes into the functionality and shape, it could have slightly modifications but it will never change the structure at its roots, the complexity of this system is
