My time at ITC is temporal, since my current CV dates from 4 years ago (I was not even a computer engineer) it’s time to prepare another one.

Show me the code!

Trailing Whitespaces Vim

Trailing whitespaces are a pain in the ass. Adding, deleting and modifying code can lead to invisible spaces at the end of the line. This is “bad” and useless.

Here comes Vim!

A substitution command :%s/<search>/<substitute>/
Where the search is for trailing whitespaces \s\+$ and the substitute is “nothing”.

Writing this every time is too much effort, it’s a good idea to define a user command:
:command Deltw :%s/\s\+$//

Or better, add the line to your vimrc file:
command Deltw :%s/\s\+$//

now just typing the command Deltw deletes those annoyances.

Some days ago while procastinating around I discovered a little software jewel:

Emerillon is named after the Émérillon, one of the three boats that visited New France under Jacques Cartier’s command in 1535. Émérillon is also French for Merlin Falcons.

How Cool is that?


1541: Cartier's Three Ships Grand Heremine, Petite Hermine, & Emerillon


Émerillon - Merlin Falcon

That Cool!

But we are not interested in the name (though I like it a lot), the software is neat.
Emerillon is a map viewer for Gnome desktop environment. It features OpenStreetMap layers and a small, easy to use interface.
The feature list is not very long (not as long as Google Earth) but it’s a nice start for a good map viewer.

The beautiful part is that it features a plugin system (currently with 4 basic plugins) that eases extensibility:

  • Search bar (using GeoNames)
  • Placemarks
  • Map Coordinates (window center latitude,longitude)
  • Link Generator (for ggmap, bing, osm)


There’s a lot of room for improvement, but it seems that the bugzilla page of the project is somewhat dead. The last commit (translation to Japanese) is from a week ago, but the last development commit dates from 2011-11-11.

It’s a shame.
