How to setup your own CA with OpenSSL

For educational reasons I've decided to create my own CA. Here is what I learned.

First things first

Lets get some context first.

How to install PhantomJS on Ubuntu

Version: 1.9.8

Platform: x86_64

First, install or update to the latest system software.

sudo apt-get update
sudo apt-get install build-essential chrpath libssl-dev libxft-dev

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.

Update May 2017

Eric Bidelman has documented some of the common workflows possible with headless Chrome over in https://developers.google.com/web/updates/2017/04/headless-chrome.

Update

If you're looking at this in 2016 and beyond, I strongly recommend investigating real headless Chrome: https://chromium.googlesource.com/chromium/src/+/lkgr/headless/README.md

Windows and Mac users might find using Justin Ribeiro's Docker setup useful here while full support for these platforms is being worked out.

Deploying a subfolder to GitHub Pages

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.

For the sake of this example, let’s pretend the subfolder containing your site is named dist.

Step 1

Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).

tmux cheat sheet

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

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:

remap prefix to Control + a

The case for Gist blogging

Why to bother?

The posts people write in blogs can be classified in two groups:

those that are going to be (or should be) maintained, expressing the real time information (like books one reads or read, todo lists, lecture notes, etc),
those that express the momentary thoughts of a writer on an event or activity.

Maintaining the post

While first ones can be managed using standart blog engines (livejournal, blogger, etc) via «Edit post» option, that’s hardly

	define(['can', 'localCache'], function(can, localCache) {
	'use strict';

	describe('storeLocal()', function() {
	var sandbox;
	beforeEach(function() {
	// create sandbox environment for mocking about
	sandbox = sinon.sandbox.create();
	});

	PhantomJS (has the engine webkit)
	download from the page http://phantomjs.org/download.html

	and then in terminal
	$ cd /usr/local/share/
	$ sudo wget https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-1.9.8-linux-x86_64.tar.bz2
	$ sudo tar jxvf phantomjs-1.9.8-linux-x86_64.tar.bz2
