Software Carpentry Workshop at UFSC

Diego openning the workshop.


I would like to thanks to Diego Barneche for the invitation to be one of the instructors of the first Software Carpentry workshop at the Federal University of Santa Catarina.

Diego, I like very much met you in person and love the time in Florianópolis.


Also, I wouldd like to thanks Renato Morais Araujo and Juliano A. Bogoni, the local organizer, for the iniciative and hard work to make this workshop possible.

Last Thursday and Friday, Diego and I ran a Software Carpentry workshop at the Federal University of Santa Catarina, based on Florianópolis or Ilha da Magia. This was a R based workshop that also cover Unix Shell and Git.

Pandas at CTBE


I would like to thanks Marcelo Valadar for the invitation to taught a Pandas introduction at CTBE.


I would like to thanks very much to Wanderson Luiz that help me solving the issues that the students had during the lesson. I hope that he finishs his PhD soon and after that get involved with Software Carpentry to have fun helping researchers to program (even with MATLAB).

Today I taught a Pandas’ introduction at the “Laboratório Nacional de Ciência e Tecnologia do Bioetanol” (CTBE), one of the laboratories of “Centro Nacional de Pesquisa em Energia e Materiais” (CNPEM).

From Graphics to Math


I recomend that you use Firefox to read this post.

Yesterday, Jure Triglav said

“I dropped by to let you know that I wrote a new post on scientific data visualization: and would love any kind of feedback you could give me”

at #sciencelab (a nice place to talk with people about how to do science in the 21st).

Jure’s post is awesome (and you should read it). The main point of it are that “a committee of several really smart people from all branches of science and engineering” wrote a document for standardizing scientific graphics in 1914.

One of the rules at this document “is essentially saying that data should accompany the figure. A hundred years later, we’re still far from applying this simple but powerful rule. Projects like The Content Mine expend a tremendous amount of energy trying to get data back from figures, and even then it’s a very lossy process. All of that could be avoided if we just follow this one simple rule.”

At Jure’s post you will find what you can do to follow this one simple rule when working with graphics. In this post I want to extend this simple rule to mathematical expressions.
