luis@11: \subsection{Software Development}
luis@11: 
luis@11: Our survey shows that 66,6\% of researchers use more than one OS. Linux isn’t
luis@11: used as a single operating system by anybody, which seems to indicate
luis@11: that most Linux users use it for multi-platform developing or for
luis@11: specific software needs. SuperCollider, Android SDK/NDK, NET, PRAAT (Speech Researcher), CUDA-C
luis@11: (GPU Programming), Clojure, Presentation, R.
luis@11: 
luis@11: Most researchers (56\%) use version control. This kind of system is
luis@11: more widely used by PHD students and Postdocs/Research
luis@11: Assistants. When asked for what kind of technologies were used, SVN
luis@11: (14) and GIT (7) were the most popular systems. CVS (5) and Mercurial
luis@11: (4) were the other available options. Many users use more than one of
luis@11: these systems simultaneously.
luis@11: 
luis@11: When asked for the usage of code hosting services, 52\% of the researchers
luis@11: said their code stayed in their computers. The most used third-party
luis@11: source code hosting services is SourceForge (6 users). 10 users are
luis@11: using university source code version control tools. \textit{remove
luis@11:   numbers, only leave percentages}
luis@11: 
luis@11: 27 users do not produce or maintain software. 16 do, while 11 did not
luis@11: answer. \textit{percentages\ldots}
luis@11: 
luis@11: Most users (57\%) do not plan to make any software available.
luis@11: 
luis@11: When asked “Do you develop any software that you do not intend to
luis@11: publish?”, 52\% of the users answered no. Possible commercial use is
luis@11: the main justification given for not publishing the software at this
luis@11: point.
luis@11: 
luis@11: \subsection{Reproducible Research}
luis@11: 
luis@11: Most researchers (56\%) acknowledge they don't take the necessary
luis@11: steps to ensure sustainable and reproducible research. Many do not
luis@11: understand the concept of reproducible research. By analyzing this
luis@11: accordingly to the current position, we can see that PhD students are
luis@11: the ones that are less aware of the importance of reproducible
luis@11: research (even the ones that are almost finishing their PhD).
luis@11: 
luis@11: Many of the researchers that ensure they do the steps necessary to
luis@11: reproducibility say they only give the code and/or data to interested
luis@11: researchers. Some researchers also say that they publish their code in
luis@11: their own pages. At the same time, there are indications that this
luis@11: procedure can lead to unsustainability itself. Many researchers
luis@11: complain about the amount of time and/or complexity of making research
luis@11: reproducible. Also many of them make only parts of their work
luis@11: available. Some researchers also complain about copyright issues in
luis@11: releasing data.
luis@11: 
luis@11: Many researchers do not understand the full concept of
luis@11: reproducibility. Some assume that explaining the algorithm and the
luis@11: tools used is enough for other researchers to be able to reproduce
luis@11: their results. Finally, some typical (but not widely admitted) answers
luis@11: justify the decision not to embrace reproducibility due to messy code
luis@11: or code/data protection:
