- GNU/LINUX - No heavy desktop environments - Getting rid of using mouse, try to be fully compliant of using just keyboard. - Use a tiling window manager {i3, awesome, bspwm, etc}. YMMV on which wm fits your needs best. - Use vim-vixen on firefox or qutebrowser for vim bindings - EMACS + EVIL Mode or Vim - There are a bunch of Terminal Emulators.. I use terminator, but you could get away with something minimal like RXVT, URXVT, or ST.
