Writing tools, and updating your dotfiles with helpers/shortcuts is absolutely useful. I had a small collection of useful utilities become somewhat popular on github, even though I mostly published them so I had somewhere central to install from. These days I've been reworking them into a single binary so that I can deploy them even more easily: https://github.com/skx/sysbox https://github.com/skx/sysbox That, coupled with my dotfiles (mostly a literate emacs config written in markdown), makes me pretty productive when moving to new systems.
