S/W Design and Architecture

Morrow wrote in his autobiography that he’d left GSS because ... he felt that the OASIS had evolved into something horrible. “It had become a self-imposed prison for humanity,” he wrote. “A pleasant place for the world to hide from its problems while human civilization slowly collapses, primarily due to neglect.” (p. 120) I deeply agree with this quote, I believe that the world would hide its problems inside Oasis, we can see that the world it's collapsing when you see the conditions in which Parzival was living on, he was living in a kinda dump. I'd love to test the Oasis and see how VR has grown. For me VR it's an incredible technology we can take advantage of, currently, I'm taking a class of VR and I can say I'm really impressed how much it has grown, it's really like if you are in another world. Sometimes I forget where I am and nowadays VR it's not as developed as in Ready Player One, so I understand how easy it can get to lost in the game.  I ...

Today's blog is about Microservices architectural style, this refers to the approach of developing a single application as a suite of small services. As I was reading the article I really understood that I did not know anything about Microservices, I had a bearly idea about it but I was on the lost path. The authors give some characteristics of microservices and I will list them. *Componentization via Services *Organized around Business Capabilities *Product not Projects *Smart endpoints and dumb pipes *Decentralized Governance *Decentralized Data Management *Design for failure *Infrastructure Automation *Evoluionary Design Every one of these explains to us what the Microservice should have, I will explain some of them.  *Componentization via Services: Components will be set up into libraries that will be broken down into services. *Design for failure: Software must tolerate the failure of the external services *Smart endpoints and dumb pipes: E...

UML diagrams are used to describe the system, the three types of diagrams are, Structure diagrams, Behavior diagrams and Integration diagrams. UML it's only a way to convey knowledge from one place to another. As we can see UML it's only a design tool. There are other useful tools that help us a lot, and it's called system architecture or software architecture, like blueprints in like in construction,  help with the design of the building. One of these helpful part of system architecture it's called 4+1 View Model. The first part of the 4+1 model is the logical one, that states what sort of objects we¿re going to build, here are described all the classes, objects and logistics of the project.  The second one it's called development view, which states to the developer how the system is organized, which part is connected to what. It's often called the "Implementation view". The process is our third view in the 4+1 view model, it describes the concur...

These 5 principles are great advice discovered by Robert Martin also known as "Uncle Bob", the same we heard a podcast blog entrance ago. His acronym makes it easier for learning his principles, whenever we're developing object-oriented programs. The 5 principles are listed down below: S ingle Responsibility Principle (SRP): States that any class should have only one responsibility, although the author at some point says that there could be some classes that have 2 responsibilities. As the author continued with his explanation it confused me a little bit, because he contradicts himself. Maybe it could be clearer with the practice, as it's with all things in life.  O pen/Closed Principle (OPC): States that a class or a function should be open for extension but closed for modification. It attempts to counter the tendency for object-oriented code to become easy to be broken.  When adding new behaviour you need to leave alone the base classes instead you...
