RailsConf 2015 Room 202 Day 1

Here's what I did to get things working.

Create droplet of your liking (ubuntu 12.10 x32)

ssh to root in terminal with your server ip

ssh [email protected]

Add ssh fingerprint and enter password provided in email

Fortunately GIT has a very easy solution for this, just run the following command on the file or path you want to ignore the changes of:

git update-index --assume-unchanged <file>

If you wanna start tracking changes again run the following command:

git update-index --no-assume-unchanged <file>

	# Base image.
	FROM fotinakis/baseimage-ruby:2.1.3

	# System dependencies for gems.
	RUN apt-get update
	RUN apt-get install -y --no-install-recommends libmysqlclient-dev

	# Add 'web' user which will run the application.
	RUN adduser web --home /home/web --shell /bin/bash --disabled-password --gecos ""

	FIX FOR: Couldn't connect to Docker daemon at http+unix://var/run/docker.sock - is it running?

	Change the DOCKER_OPTS in /etc/default/docker to:
	DOCKER_OPTS="-H tcp://127.0.0.1:4243 -H unix:///var/run/docker.sock"

	Ruslan Khamidullin [1:57 PM] netstat -ant \|grep 4243
	tcp 0 0 127.0.0.1:4243 0.0.0.0:* LISTEN

	Ruslan Khamidullin [1:57 PM] export DOCKER_HOST=tcp://localhost:4243

	<li class="<%= self_or_other(message) %>">
	<div class="avatar">
	<img src="http://placehold.it/50x50" />
	</div>
	<div class="chatboxmessagecontent">
	<p><%= message.body %></p>
	<time datetime="<%= message.created_at %>" title="<%= message.created_at.strftime("%d %b %Y at %I:%M%p") %>">
	<%= message_interlocutor(message).name %> • <%= message.created_at.strftime("%H:%M %p") %>
	</time>
	</div>

	These are the solutions to all the "experiments" in the pre-release Swift Programming Guide
	(released on the same day Apple announced Swift). A couple of things worth noting:

	1. Swift syntax, e.g. array declarations, has changed since I releasd these. So this code will
	probably cause some errors when you paste it into a playground. Should be easy enough to fix

	require 'openssl'
	require 'digest/sha1'
	require 'base64'
	require 'json'

	def go_demo!

	key = Digest::SHA1.hexdigest("clave1")[0..15] # 16bytes => 128bits
	iv = 'clave2 con chicha'[0..15] # 16bytes forced
	data = { esto: 'es', un: 'hash', en: 'ruby' }
