(C-x means ctrl+x, M-x means alt+x)

remap prefix to Control + a

# how to set up the virtualenv used in this

# First move org.lolrus.ipython-notebook.plist to ~/Library/LaunchAgents

NOTEBOOK_DIR=${HOME}/notebook

brew install zmq

which virtualenv > /dev/null || sudo easy_install virtualenv  # easiest to install virtualenv this way if you dont have it

Budi's CS:GO Config

This is my constantly updated CS:GO autoexec config. Changelogs can be found under revisions here

Put autoexec.cfg in ...\Steam\steamapps\common\Counter-Strike Global Offensive\csgo\cfg or take what you want from it and add to your autoexec config!

After the Wild West Simulator 2015 update, video.txt needs to be put in ...\Steam\userdata\<Steam3 ID>\730\local\cfg
