What are you working on? February 2013

This is the bimonthly 'What are you working On?' thread. Previous threads are here. So here's the question:

What are you working on?

Here are some guidelines:

Focus on projects that you have recently made progress on, not projects that you're thinking about doing but haven't started.
Why this project and not others? Mention reasons why you're doing the project and/or why others should contribute to your project (if applicable).
Talk about your goals for the project.
Any kind of project is fair game: personal improvement, research project, art project, whatever.
Link to your work if it's linkable.

Coursera's Data Analysis (basically applied R); it's going well so far.
my second (blinded, standardized doses upon awakening) potassium self-experiment is nearing completion; my subjective estimate is that there is still some damage to my sleep. Another longer-term self-experiment should also finish in February, but I'm not sure whether I will discuss it publicly.
working on another big expansion of my hafu database; I discovered that it's actually pretty trivial to scrape the HTML into an R data frame and manipulate, so I can finally see what the data looks like, but I also noticed that some of the data was messy or wrong and that I had omitted hair & eye color. This motivated me to clean it up and spend 2 days adding that data, and soon I'll start looking for entries from my last source of leads. Then I can finally write up an analysis and have something to show for all my time.
