Working on my research today, feeling pretty amazed at the range of free software and services available to me that enable me to do so.  GNU, Linux, bash, emacs, spacemacs, vim, PHP, codeception, git, github, travis, TeX, LyX.  Eclipse, FeatureIDE.  Whatever all of these themselves are built on.  DuckDuckGo, StackOverflow and blogs helping with questions.  Plenty more I’m sure I’ve missed out.  Flipping awesome, this ecosystem.
