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:

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.

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:

Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

Revert the full commit

Sometimes you may want to undo a whole commit with all changes. Instead of going through all the changes manually, you can simply tell git to revert a commit, which does not even have to be the last one. Reverting a commit means to create a new commit that undoes all changes that were made in the bad commit. Just like above, the bad commit remains there, but it no longer affects the the current master and any future commits on top of it.

git revert {commit_id}

About History Rewriting

Delete the last commit

Deleting the last commit is the easiest case. Let's say we have a remote origin with branch master that currently points to commit dd61ab32. We want to remove the top commit. Translated to git terminology, we want to force the master branch of the origin remote repository to the parent of dd61ab32:

	#--coding:utf-8--

	import hashlib
	import hmac
	import time
	import requests

	HMAC_KEY = '5tT!TQkf5fYbabw5?KL2659XgL^JgxWw8r9Y+bAvGwP-QfteQL'

	class TanTan(object):
