I'm a long-time user of free/open source software, and write various things for both fun and profit. I don't take myself all that seriously and I do all of my own stunts.
You can find me at these fine establishments on the web: Open Source Musings, The Monday Kickoff, Weekly Musings. and The Plain Text Project.

Qlik (the company) has a bunch of repos on GitHub. I don't know whether or not the contents of those repos make up the entire QlikView or QlikSense systems.
Good choice! Funny you mention that. The idea for this article grew out of a talk about command line tools for the non techie. Someone suggested that I include applications like tpp and mdp, and someone else suggested I present my slides with one of them. Neither happened, but those suggestions planted the seeds for what you read.
