Hi! I am a doctoral student at the Computer Graphics Laboratory (LGC), at the Federal University of Rio de Janeiro (UFRJ), and I am currently studying how to apply data visualization to neuroscience experiments in the non-human primate visual cortex. Read more about myself and the goals of this website in the About section.

This website is a sort of all-in-one solution to the following needs:

  • Showcasing my expertise to fellow researchers and likely employers (see Curriculum and Publications)
  • Sharing and discussing knowledge with fellow researchers and programmers about various topics (see Notes and Archives)
  • Building an open and ever-evolving personal knowledge base (see Notes)
  • Granting access to lecture materials to past and future students (see Teaching)

After all it’s so much easier to keep everything (up-to-date) in one single place.

One of its interesting features is spell checking, the basics of which are covered in many tutorials out there (and, of course, in the built-in help command through :help spell, if you’re feeling geekier). In this post, I’m solely concerned with the topic of generating a custom dictionary for spellchecking using a non-English language, say, Brazilian Portuguese (usually represented by the pt_BR localized language code [1]).

This post tells the short tale of how I became slightly more enlightened on POSIX-compliant file access in Python… and how I managed to close the files, of course.
