Prereq:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

    General style is clean, with minimal re-definition of the defaults or 
    overrides of user font settings. The body text and header styles are 
    left alone except title, author and date classes are centered. A Pandoc TOC

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

A Very Short Guide to Writing Guides

This is just a few thoughts on the topic of writing technical guides. This was intended for Basho's engineering team, but this may apply to open source projects in general.

Audience

It's commonly preached that the first step in writing is to identify your audience; to whom are you writing? This is the most well known, most repeated, and most overlooked step of writing in general and technical writing in particular. Take this document, for example. My audience is technical people who need to communicate technical information, and not teenagers, so I shy away from images of pop icons and memes. I use jargon and words like "identify" rather than "peep this".

OBSOLETE

This entire guide is based on an old version of Homebrew/Node and no longer applies. It was only ever intended to fix a specific error message which has since been fixed. I've kept it here for historical purposes, but it should no longer be used. Homebrew maintainers have fixed things and the options mentioned don't exist and won't work.

I still believe it is better to manually install npm separately since having a generic package manager maintain another package manager is a bad idea, but the instructions below don't explain how to do that.

Fixing npm On Mac OS X for Homebrew Users

Installing node through Homebrew can cause problems with npm for globally installed packages. To fix it quickly, use the solution below. An explanation is also included at the end of this document.
