Here are two small sites I made recently, and which I may continue to tweak and expand. The first,
plain-text.co, presents “The Plain Person's Guide to Plain-Text Social Science”. It is designed to address some questions about managing research and writing projects in the social sciences using plain-text and free or mostly-free tools like Emacs (or other text editors), R,
make. The second,
vissoc.co which I've mentioned before, compiles notes from a short course in data visualization I taught last semester. In both cases, the source files behind the sites are available on github, along with various templates, examples, and configuration files (more about those here) meant to make your plain-text coding and writing life a little easier.
