Scrum!!!

Ultimamente eu ando estudando sobre Scrum. Scrum é um processo de desenvolvimento de software, que basicamente pode ser utilizado em java, .net, ruby e outras linguagens. Scrum é uma forma de desenvolvimento agile, porem está muito focado nas pessoas e no 'time' em si. Uma diferença significativa é que no Scrum nos não temos fazer incrementais como no RUP. Nos temos no mesmo ciclo: analise, arquitetura, codificação e teste. No Scrum são feitos releses rápidos que duram entre 2-4 semanas, como ele é um processo não uma metodologia ele pode ser adaptado conforme a sua necessidade.

Esses releses curtos são chamados de sprints que são 'corridas', ou seja, entregas rápidas, assim nos vamos ter entregas incrementais. A Data da entrega(sprint backlog) é sacro-santa, isso é, não pode ser mexida, o que pode ser feito é diminuir o número de products backlogs(requisitos) , mas nunca alterar a data.






















A partir da figura a cima, podemos ver em sintese como é o ciclo de processo no Scrum de maneira macro. Tudo parte de um Product Backlog que é a definição do produto final a ser produzido, nesse item temos diversas entradas(histórias ou requisitos) como por exemplo: Em um sistema bancário: Solicitar empréstimos, fazer transferência bancária, financiar casa, etc...
O Time(pessoal de TI) escolhe junto com o product owner(dono do produto) quais história vamos ser entregues nesse relese. Esse relese é chamado de sprint. Entre 2-4 como dito antes existem as entregas desses Sprints. A cada dia existe uma daily Scrum meeting, que é uma reunião de 15min no máximo, para ver as principais dificuldades, o que foi feito no dia anterior, e o que será feito no próximo dia. E no final vamos tendo um produto funcional e incremental, a cada ciclo de Sprint nos temos mais funcionalidades agregando valor ao produto.

Vou começar a postar mais sobre Scrum aqui! Gostaria de deixar algumas referencias, caso o assunto tenha despertado interesse. :)

C Unit Testing with Check

Image
When I start on IT, several years ago(+15), C was the first language that I learned. But was not the first language I mastered and deployed in production which was...surprisingly Visual Basic 6.0. However, when I learned C or any language back on that old and arcane time noddy was into testing. However now is impossible to work professionally in any language without tests. C is a low-level language but still kicks ass and has several interesting libs/frameworks. People use to fear C a lot because of lack of syntactical sugar but once you get used to it is not that hard at all. Today I want to show how you can do Unit Testing with C. I will not show how to do Unit Testing with C++ but with C ANSI actually. We will be using Check a unit test lib for C ANSI.

Having fun with Zig Language

Image
Zig is a general-purpose language created in 2016 by Andrew Kelly .  Zig aims to fix the issues C language has while being pragmatic and simple at the same time. Zig really shines as being simple by not having any hidden control flows, not having hidden memory allocations, no pre-processors, and no macros. Basically, it's one language and one language only. Since pre-processors and macros can get really complex and become their own universe. Sure it's not the Zig Philosophy.  Zig Compiler(Zig cc) also is a C compiler, and the interoperability from C to Zig is very good. Clearly, we can see influence from other languages like Go and Rust; however, Zig is pretty unique and different from Go and Rust.  Zig is fast. Zig is perfect for system programming. I bet we will see a lot of solutions being built in Zig. As a languages aficionado, I like to learn at least one language per year and sometimes more; Zig was my 2021 pick, did not regret it. Even if you dont use all language...

HMAC in Java

Image
In 2018 AWS CTO(Vogels) said : "Security is everyone's job". For the last 2 years, there was so many famous and big data leaks and breaks that made that statement be very true more than ever. Security often could mean worst performance and worst user experience so in order to get it right you really need to think about the designs before jumping into to code and consider performance and user experience has main requirements.  I was thinking about writing about how to do HMAC in Java for a while and recently Redis 6.0.0 come out and to my surprise, there was a refactoring on the password part in order to use HMAC.  Security easily could scare engineers often because it is not something well spread yet but I believe this will change soon. It does not matter if you have to deal with PII Data or not, security is super relevant because everybody is running their workloads at the cloud or with IoT and Edge devices which means more distribution, more code, more points of fail...
