I am fluent in Python and Fortran, have written a decent amount of ruby and bash, and dabbled in a variety of other languages.
My work on the open-source Modules for Experiments in Stellar Astrophysics project included significant technical contributions, such as leading the project’s migration from SVN to Git/GitHub and redesigning its testing infrastructure.
I run Arch Linux on a Lenovo X1 Carbon, using the xmonad window manager. Some of my dotfiles, including my xmonad.hs, are available on GitHub.
My editor of choice is emacs. I make extensive use of Org Mode to manage my TODO list, write presentations, etc. I frequently use Magit to interface with git. I often read and write my mail using mu4e.
I occasionally write short posts related to some of these topics.
