So I bombed the AIND, for a variety of reasons. I haven't done a whole lot of programming in the mean time, except one failed attempt at writing a simple service manager in Go. A couple of people have started working through Open Data Structures; I'm working on it in C++.

I did enroll in the Machine Learning nanodegree, so we'll see how that goes. I've gotten through the first practice problem, building a spam classifier, but I haven't figured out how to get the scikit-learn classifier to work with a single text message. I've also gotten through the first optional project, the Titanic survival exploration. It was a little bit of a pain to sift through the data, but I finally got to a more than 80% accuracy (80.36%!). Now, I'm through the model training and testing section and working on the first actual graded project.

I've been kicking around the idea of building a robot again --- using LIDAR to build up an environment. This would be a simplified robot, using the 4WD chassis I have, with only a servo-mounted LIDAR.

A friend told me about The Immortal Life of Henrietta Lacks and combined with the theme of the new season of Black Mirror (uploaded souls) has been making me think about AI ethics. As I read through the book, I'll be keeping an eye for parallels between the two.
