How to install applications

I prefer installing app managers and getting apps from them. For instance, it is a lot easier to install apps from Mac App store, however, not all apps are distributed that way. Hence, get brew and cask for brew. brew is a Homebrew project which gives a CLI for installing and updating apps. In no time, you can update and manage apps like you manage Python or Java packages using conda or maven.

Installing brew

Get brew by pasting

# Hacky script for downloading videos from PyVideo and converting them to m4v 
# format so they can be synced onto your apple device.  Useful if you
# want to see everything that happened at PyCon while commuting.
# 
# Requirements:
# * pip install requests BeautifulSoup
# * youtube-dl (from https://github.com/rg3/youtube-dl/) - add this to the 
#   directory where this script runs and ensure its execute bit is set.  
#   This was the only YouTube downloader I found that worked.  It doesn't 
#   really have a good Python API so I call it through os.system.

How to checkout a branch from a fork of your repo?

git remote add <name> <url.git>

This adds the forked repo as a remote. You don't need this if you have merge privileges. You can then fetch and checkout the branch of your choice

git fetch <name or remote>
git checkout  # allow tab completion to help you here.
