Desenvolvimento MVC RAD com Stripes

MVC É de fato um padrão desenvolvimento em camadas, que basicamente se caracteriza por separar a camada de negócio(Model) da camada de apresentação(View). Nesta arquitetura temos diversas soluções consolidadas como: Struts, Spring MVC, MyFaces(JSF), ADF(JSF ORACLE), JBoss RichFaces(JSF), entre tantos outros. Mas hoje eu venho lhes falar do Stripes, que é uma framework baseado na arquitetura MVC porem o Stripes é muito RAD, com ele podemos desenvolver uma solução WEB com pouco esforço e praticamente zero de configurações xml. O Stripes utiliza o conceito onRails e consegue fazer mais convenções e menos configurações. Alguns pontos importantes sobre o Stripes:



  • Desenvolver aplicações Web de maneira fácil.

  • Prove soluções simples e poderosas para problemas comuns.

  • A Curva de aprendizado é muito baixa.

  • Se você necessita configurações muito especificas pode usar annotations.



    Eu baixei o Stripes versão 1.4.2 e fiz alguns testes.



    Foi bem simples de aprender como usa-lo o aprendizado foi fácil.



    Ele se integrá como diversos frameworks como: Spring, Hibernate,Freemaker, Ajax(Prototype), entre outros.



    Utilizei ele com Ajax via prototype e também em conjunto com Spring.



    Para linkar a tela(view) a uma Action não precisamos de XML. O Stripes usa seu mecanismo onRails de convenções, assim:



    Supondo que temos no package: org.diegopacheco.stripes.test.spring a classe: CalculatorActionBean para ligarmos essa Action a uma JSP é só fazer isso: o Stripes faz:



    # remove tudo que tem antes de Stripes

    org.diegopacheco.stripes.test.spring.CalculatorActionBean.java



    #ficando: test.spring.CalculatorActionBean.java

    test.spring.



    # e por ultimo ele Remove o sufixo Action e passa para .action ficando

    test.spring.Calculator.action



    Este mecanismo de convenções é muito poderoso e produtivo. Caso por algum motivo você não queira usar esse mecanismo podemos fazer o mapeamento do Action via: a annotations @UrlBinding assim: @UrlBinding("/test/spring/Calculator.action").



    A Documentação do Site do Stripes é muito boa, façam bom proveito.

    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...
