I've started experimenting with an Intel Edison and the Sparkfun Starter Pack for Intel Edison. Things have gotten off to a good start, but I missed the nano editor. I couldn't install nano using opkg, but the following code will download the source code (using wget), compile it, and install it.
wget http://www.nano-editor.org/dist/v2.4/nano-2.4.1.tar.gz && tar xvf nano-2.4.1.tar.gz && cd nano-2.4.1 && ./configure && make && make install
As of June 2015, nano 2.4.1 is the latest version. Update the numbers in the line above for other versions. You can see what's available by browsing http://www.nano-editor.org/dist/.
I've been able to get C code working that reads from an I2C sensor. I'll post about that shortly.
