Understand Pointers, simple and easy with Go

Lidar com ponteiros pela primeira vez assusta quem vem de linguagens como JavaScript, Python ou Java, onde a gestão de memória é automática Mas a ideia é mais simples do que parece. O que são ponteiros? Toda variável ocupa um espaço na memória, e esse espaço possui um endereço. Um ponteiro é uma variável que guarda o endereço de outra variável , em vez de guardar diretamente o seu valor. x := 10…

The article explains the concept of pointers in programming, specifically in the Go language. It describes how pointers store the memory address of a variable, allowing multiple references to the same data instance. The use of pointers is illustrated with examples, including how they enable modification of the original data and avoid unnecessary copying.

In Go, the article notes that it's common to use value types by default and reserve pointers for situations where shared or modified instances are needed, or to represent nil or avoid large copies.

Frontend DevOps: My Resource Map As we know, Frontend DevOps is a relatively new concept that has been gaining popularity in recent years. In order to implement it effectively, it is essential to have a clear understanding of the resources required. In this article, we will explore the different resources needed to implement Frontend DevOps. First, it is crucial to have a good understanding of the current state of Frontend DevOps. This involves knowing the tools, technologies, and methodologies used in the development and deployment of frontend applications. Some of the key resources required for Frontend DevOps include: - Knowledge of programming languages such as JavaScript, HTML, and CSS. - Familiarity with frontend frameworks such as React, Angular, and Vue.js. - Understanding of version control systems such as Git. - Knowledge of continuous integration and continuous deployment (CI/CD) tools such as Jenkins, Travis CI, and CircleCI. - Familiarity with containerization tools such as Docker. - Understanding of monitoring and logging tools such as New Relic, Datadog, and ELK Stack. In addition to these technical resources, it is also essential to have a good understanding of the methodologies and practices used in Frontend DevOps. Some of the key methodologies and practices include: - Agile development methodologies such as Scrum and Kanban. - Test-driven development (TDD) and behavior-driven development (BDD). - Continuous testing and continuous deployment. - Monitoring and feedback. Having a clear understanding of these resources is crucial for effective implementation of Frontend DevOps. In the next article, we will explore how to implement Frontend DevOps in a real-world scenario.

Pasar de Frontend Engineer a DevOps Engineer implica aprender un montón de cosas nuevas: infraestructura, redes, contenedores, CI/CD, y una forma distinta de pensar los sistemas.
