Vagrant on Mac w Virtualbox

NSoT engineers have built Vagrantfiles for you to deploy NSoT software in a multitude of linux environments. This tutorial will help you load a Macintonsh computer (OS X) with Vagrant, Virtual Box, and dependencies so that you can start virtual servers and test the software.

NSoT publishes complete installation instructions for linux distributions, branch versions, and Vagrantfiles in addition to, not an alternative for the pip install method:

$ pip-install nsot

PdfLatex is a tool that converts Latex sources into PDF. This is specifically very important for researchers, as they use it to publish their findings. It could be installed very easily using Linux terminal, though this seems an annoying task on Windows. Installation commands are given below.

Install the TexLive base

sudo apt-get install texlive-latex-base

Also install the recommended and extra fonts to avoid running into the error [1], when trying to use pdflatex on latex files with more fonts.

Powerline-patched Monaco for Windows and OSX

This font is manually patched with Fontforge. It includes the glyphs from DejaVu Sans Mono for Powerline.

I recommend DirectWrite-patched VIM builds. I'm using KaoriYa's build (http://www.kaoriya.net/software/vim/)

Usage

Add the following lines to your .vimrc/_vimrc:

	# To do the custom build we use 2 modules: --with-http_secure_link_module --with-http_flv_module
	# This module "secure-link" helps you to protect links from stealing away.
