Vectorize an image using Inkscape

And now, for something completely different.

For a coming event we want to use logos from different bars and cafes around the block. The idea is to do a little of propaganda: banners, t-shirts, mugs all the way!

Some bars have their fancy logos already as a vector image. Other ones don’t even have a computer where the logo is stored.

In this post we’ll see how to create a vector file from a pixmap (jpg, png, whatever raster format that Inkscape can open). With a couple of examples, a graceful one and a crazy one.

There’s a lot of manuals online for this, an in-depth one with good examples can be found in Tavmjong Bah’s website.

vectorizing!

Create a module with XCircuit

xcicon_sm

I discovered XCircuit when looking for an easy and quick way to generate a schematic.
Since I am not going to simulate it, it would be enough to have a vector design program like Inkscape, but it’s never too late to learn a tool that may prove useful in the future.

There are other bigger, better, stronger EDA tools: Geda, KiCAD, EagleCAD… but I settled for something designed for publications.

(…)program for drawing publishable-quality electrical circuit schematic diagrams and related figures(…)
— XCircuit website

In this post you’ll find a quick overview of XCircuit, and how to create a module with it.

A better way to Jenkins

jenkins_logo

Jump around, Jump around. No maps this time, but Continuous Integration. My current work involves a lot of a software piece called Jenkins. I’ve been swimming with it the last 2 months and I feel compelled to share how we changed our ways.

This post is an overview guide on how to configure Jenkins to generate the jobs that are defined in a git repo.

let’s integrate continuously

Emerillon

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

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?

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)

Screens!

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.
