The thing you keep forgetting? The thing that makes Samba actually work instead of being a teeth-grinding night of frustration?

sudo smbpasswd username

Working with git branches

Starting work on your new branch

cd path/to/myapp
git checkout develop
git pull
git checkout -b feature/my-new-feature

(updated version of http://www.joyceleong.com/log/installing-phantomjs-on-ubuntu/)

export P=phantomjs-2.1.1-linux-x86_64
cd /usr/local/share
sudo curl -L -o $P.tar.bz2 https://bitbucket.org/ariya/phantomjs/downloads/$P.tar.bz2
sudo tar xvf $P.tar.bz2
sudo ln --force -s /usr/local/share/$P /usr/local/share/phantomjs
sudo ln --force -s /usr/local/share/phantomjs/bin/phantomjs /usr/local/bin/phantomjs
phantomjs --version

Storing relationships in a relational database

Approach 1: least data, simplest schema

The simplest way to store bilateral relationships is in a relationships table, with the subject (party_a) of the relationship in one column and the counterparty (party_b) of the relationship in another.

Schema

Column	Type	Description

This is my personal memo for setting up new Ubuntu servers in my environment. It may not be appropriate for your environment but feel free to use it as a starting point.

During setup

Accept all defaults except as listed here.
For the machine name use the full name including the local domain, e.g. new-server.local.domain
Add a user for all build tasks, name is Build, username is build
Do not encrypt the home directory.
Do not use LVM

sudo su
apt-get install ssh openssh-server
pico /etc/network/interfaces

iface eth0 inet static
	address		192.168.1.99
	netmask		255.255.255.0
	network		192.168.1.0
	broadcast	192.168.1.255

What I actually did

	Feature: Config
	In order to configure Foreplay
	As a CLI
	I want to be as usable as possible

	Scenario: Check configuration parameters - invalid parameter
	When I run `foreplay check --invalid xyz`
	Then the output should contain:
	"""
	ERROR: foreplay check was called with arguments ["--invalid", "xyz"]

	You are using WebMock 1.16.1. VCR 2.8.0 has been tested against WebMock >= 1.8.0, < 1.16, and you are using a newer version. If you experience VCR issues, consider downgrading WebMock as it may fix it.
