pg_dump is a nifty utility designed to output a series of SQL statements that describes the schema and data of your database. You can control what goes into your backup by using additional flags.
Backup: pg_dump -h localhost -p 5432 -U postgres -d mydb > backup.sql

Restore: psql -h localhost -p 5432 -U postgres -d mydb < backup.sql

-h is for host.
-p is for port.
-U is for username.
-d is for database.

git checkout master # you can avoid this line if you are in master...
git subtree split --prefix dist -b gh-pages # create a local gh-pages branch containing the splitted output folder
git push -f origin gh-pages:gh-pages # force the push of the gh-pages branch to the remote gh-pages branch at origin
git branch -D gh-pages # delete the local gh-pages because you will need it: ref

Some of the Redis best practices content has moved

This content from this markdown file has moved a new, happier home where it can serve more people. Please check it out : https://docs.microsoft.com/azure/azure-cache-for-redis/cache-best-practices.

NOTE: Client specific guidance listed below is still valid and should still be considered. I will update this document once all content has been moved.

Install Terminator (shell)

sudo add-apt-repository ppa:gnome-terminator
sudo apt-get update
sudo apt-get install terminator

Terminator should be setup as default now. Restart your terminal (shortcut: "Ctrl+Alt+T").

Install ZSH

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).

	FROM ruby:2.3.1

	# Install dependencies
	RUN apt-get update -qq && apt-get install -y build-essential libpq-dev nodejs

	# Set an environment variable where the Rails app is installed to inside of Docker image:
	ENV RAILS_ROOT /var/www/app_name
	RUN mkdir -p $RAILS_ROOT

	# Set working directory, where the commands will be ran:

	<%# Put this code snippet between the <head></head>-tags in your application layout and %>
	<%# replace 'UA-XXXXXXXX-X' with your own unique Google Analytics Tracking ID %>

	<%# ... %>
	<head>
	<%# ... %>
	<% if Rails.env.production? %>
	<script type="text/javascript">
	(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]\|\|function(){
	(i[r].q=i[r].q\|\|[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),

	require "active_record"

	namespace :db do

	db_config = YAML::load(File.open('config/database.yml'))
	db_config_admin = db_config.merge({'database' => 'postgres', 'schema_search_path' => 'public'})

	desc "Create the database"
	task :create do
	ActiveRecord::Base.establish_connection(db_config_admin)

	namespace :db do
	require "sequel"
	Sequel.extension :migration
	DB = Sequel.connect(ENV['DATABASE_URL'])

	desc "Prints current schema version"
	task :version do
	version = if DB.tables.include?(:schema_info)
	DB[:schema_info].first[:version]
	end \|\| 0
