Intel Edison

Procedure to Autostart the Arduino Sketch on Edison

There are many ways to do this, but on Intel Edison I found that the easiest way is using the /etc/init.d directory.

Create a file in /etc/init.d

cd /etc/init.d

Here's an example of how to embed a Gist on GitHub Pages:

{% gist 5555251 %}

All you need to do is copy and paste the Gist's ID from the URL (here 5555251), and add it to a gist tag surrounded by {% and %}.

# When you’re using Maven in an IDE you often find the need for your IDE to resolve source code and Javadocs for your library dependencies. There’s an easy way to accomplish that goal.

mvn dependency:sources
mvn dependency:resolve -Dclassifier=javadoc

# The first command will attempt to download source code for each of the dependencies in your pom file.

# The second command will attempt to download the Javadocs.

# Maven is at the mercy of the library packagers here. So some of them won’t have source code packaged and many of them won’t have Javadocs.
