Better Science Through Art

CCSL sponsors the coming of two big names of Computer Science to Brazil. They will be here next week (March 30th, 31th), at the Event “Better Science Through Art” with Joe Yoder and Richard Gabriel. The event will be awesome and FREE!

Common wisdom says that science and art are entirely different beasts; moreover, a similar source of wisdom tells us that science is valuable to society while art is a luxury. Why else would schools drop art from their curricula over the past 20 years? But artists and scientists approach their work in similar if not identical ways.

Using your Hack abilities to help Japan

I’ve just received this message from Elizabeth Sabet, and I’d like to share it with all my friends. If you can help, please go ahead! Use your technical skills for the good of others:

As we watch with shock and profound sadness the tragedy unfolding in Japan and across the Pacific rim in the wake of the Sendai earthquake, our hearts and sympathies are with the families affected and their loved ones around the world. Both personally and professionally, we are deeply sensitive to the challenges now facing that region.

More about CHOReOS

The CHOReOS Solution

CHOReOS will implement a framework for scalable choreography development. The goal is to enable domain experts to develop decentralized ultra-large scale (ULS) solutions composed of heterogeneous services that are adaptable and QoS (Quality-of-Service) aware. Prior to this, these solutions were only possible with the support of dedicated IT professionals to provide the skills needed for architectural design and software engineering.
CHOReOS will deliver formally grounded abstractions and models, dynamic choreography-centric development processes, governance and service-oriented middleware manipulated via an Integrated Development Runtime Environment (IDRE) aimed at overcoming the ULS impact on software system development.

What is CHOReOS?

Next month I’ll start my PhD program @ University of São Paulo.

I’ll work on a project called CHOReOS – Large Scale Choreographies for the Future Internet. People are asking me what is this project, what I will study, what exactly I’ll do and I have a simple answer to these questions: I don’t know. I mean, I don’t know exactly. But I know it’s cool and that I will be involved with great people. That’s enough.

Até logo Locaweb

Como muitos de vocês sabem, hoje é o meu último dia de Locaweb. Foram 4 anos, muitos projetos, muitas linhas de código escritas, alguns servidores colocados em produção, alguns legados arrumados, várias tecnologias e técnicas novas aprendidas. Durante esses mais de 4 anos de empresa, aprendi muita coisa com muita gente, das quais me orgulho muito de ter conhecido e trabalhado junto. Vocês me ensinaram muito, me ajudaram muito e gostaria de dizer que sou profundamente agradecido por isso.

Technology Glossary

Here’s a small table of many terms I’ll have to be used to in my PhD program, which starts on the next month. It’s just a small part of hundreds of abbreviations we software developers have to deal with on our daily work. Please comment down if you have suggestions to add to this table. I’m sure every person can add at least 30 itens to this table:

a.k.a. Also known as

Monkey Patch em Javascript

Monkey Patch é uma técnica de programação bem conhecida para modificar código runtime em linguagens dinâmicas (Smalltalk, JavaScript, Objective-C, Ruby, Perl, Python, Groovy, etc.) sem alterar o código fonte original. Programadores Ruby estão bem acostumados a criar novos métodos para classes já existentes. O Rails faz isso em várias classes do Ruby, por exemplo, adicionar o método to_xml à classe Hash. A maneira de fazer isso em ruby é:

  class String
    def meu_novo_metodo
       return self + "-> alterada"
  # "essa string".meu_novo_metodo retorna "essa string-> alterada"
