An Analysis of Interactions on the Boston Subway

I made my first ever visit to Boston this past week, and while I was there, I was able to put together a small research project. On a subway ride, I carefully noted each of the interactions between the 50 riders in the train car I was in, during a 15 minute ride. Edge weight represents number of minutes spent talking to each other.

Nodes are colored based on degree centrality, sized based on eigenvector centrality, and spaced with Fruchterman-Reingold in Gephi.

So far, the research is merely descriptive, but I think some real insights could be made through running an actor-oriented model.

.vimrc and Dropbox

If you have used vim for very long, you have almost certainly made some modifications to your .vimrc file - this is the file that stores configurations for how vim does things like tabs, syntax highlighting, etc.

If you use more than one computer, I highly recommend keeping your .vimrc file on the cloud. It's incredibly simple, and provides for a consistent experience across computers.

This Stack Overflow post gives simple instructions on how to do this.
