Como iniciar na carreira de desenvolvedor de software

Como iniciar na carreira de desenvolvedor de software Ainda vale a pena ser um programador? A carreira de desenvolvimento de software teve um crescimento gigantesco nos ultimos anos.

A internet ainda caminhava a passos lentos e os telefones, além de ligacoes, apenas enviavam SMS.

My Kubernetes Certifications and why you should be a certified professional

The context I’ve never been a huge fan of IT Certifications. I tend to believe that one’s ability to search for information associated with a good practical expertise is much more valuable than plain memorization. On the other hand, some certifications force us to go the extra mile and to study an unusual topic. That singularity captivates me. Following that path, these last months I focused on two different Kubernetes certifications: CKA (Certified Kubernetes Administrator) and CKAD (Certified Kubernetes Application Developer).

TDC Recife - From OOP to High Order Functions

What it’s about Slides from the TDC Recife 2020 edition. On this talk I touched some topics related to a past experience moving from OOP to High Order Functions in Go.

Righ after the transition phase they were coding using a more procedural/OOP approach, but after a couple of weeks the code evolved to a more idiomatic Golang.

Redhat defines it as: Ansible delivers simple IT automation that ends repetitive tasks and frees up DevOps teams for more strategic work. — Ansible website I’m assuming that you’re familiar to the concepts of devops, infrastructure as code and configuration management, so I’m not going to detail them here.

Application, Evolution and Monitoring

The essence of software development I have already written here, that when we start coding the most important thing that we should keep in mind is maintainability. Even with other methods than scrum, like waterfall or “perfect planning”, it’s really hard to know beforehand exactly how to develop your system/application. So, if you want to deliver a good software and a great experience to your customers, you should invest time and energy building a high flexible system.

Why and how you should code to interfaces - and high-order functions

One famous debate that emerges in every design discussion is about interfaces. As always, each programmer has a different conception about it and it’s something almost inevitable to spend hours arguing about. Even when the discussion isn’t about whether or not we should use it, it’s about how to use it. As a programmer, I have my own opinion as well. I expect to give you an overview about the importance of interfaces when you should or not use it, and what you can apply it to.
