Below are some introductory articles and videos. Download R […]

Remember: good thoughts are clear thoughts and that’s much harder than it sounds when your job is to think about so much, so often, for so long. To put it simply, we have a lot of stuff in our heads.

October Squad Ghouls Network Take-Over: Postmortem
