My second article has been recently published online at Linux Journal. You can read Grabbing Your Music from YouTube: Do It Your Way by visiting http://www.linuxjournal.com/content/grabbing-your-music-youtube-do-it-your-way.
I hope you enjoy. Feel free to share your feedback. Happy hacking.
PS: My first Linux Journal article was Structure Synth: Turn Your Linux Box Into an Abstract Art Machine with a Powerful Tool.
