Osgi: The Future is Now

Pessoal recentemente o pessoal do eclipse lançou um portal sobre Osgi, mais especificamente um portal sobre Equinox, que é a implementação de Osgi para eclipse. O eclipse já utiliza Osgi em seu cerne desde a versão 3.X. No novo portal sobre Equinox existem webinar no site com vídeos introdutórios muito interessantes.

O Que vem por ai?

Aspect: É um modulo Osgi que irá permitir o uso de AspectJ dentro da plataforma Osgi.

Resource Monitoring: É um modulo Osgi que prove monitoramento de recursos contidos em bundles instalados na maquina host, basicamente utilizando JMX.



Security: É um modulo Osgi que ira prover segurança de dados, autenticação e autorização dentro da plataforma Osgi, basicamente utilizando JAAS.

Osgi Next: É um projeto em que são desenvolvidos as implementação para protótipos e análise de impacto sobre a versão do eclipse corrente.

Server Side: Esse é o cara. Suporte a especificação completa de Jsps e Servlets, exite um bundle Osgi embarcado com o Jetty, assim podemos desenvolver Servelts/Jsps dentro de Bundles Osgi e usar o Jetty como um Bundle Osgi. O Projeto ainda possibilita usar o Toncat ou outro servidor de aplicação pois existe esse war que podemos distribui-lo em um servidor de app e esse war ira subir a plataforma Osgi/Equinox no servidor de App. Você encontra mais informações aqui!

A Maneira que eles fizeram isso foi simples, porem muito inteligente, eles fizeram um registry, assim cada Bundle Osgi que quizer fazer um Sevlet por exemplo registra esse servlet.
Existe um modulo de bridge que só delega para um mecanismo de mapping. Esse mecanismo é simplesmente um ProxyServlet que está sendo usado como Wrapper para todas as requisições, esse cara guarda um Map em memoria com todos os mappings dos servlets e assim ele faz o roteamento.

Esses projetos ainda estão na incubador do eclipse, porem acredito que logo irão amadurecer e serão excelente soluções para plataforma Osgi. Não deixem de ver esse video.

Abraços.

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 languages in p

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
