2015/4/24 追記 - Ubuntu 15.04 (Vivid Vervet) では特に工夫しなくともすんなり動作するようになった模様です。ということで、インストール時には 15.04 を選ぶようにしましょう。

下記は 14.04 向けの古い情報となります。

Dell の XPS 13 (2015) に Ubuntu を入れたら幸せになれるのではないか。そんな気がしたので入れてみたのですが、案外に気をつけるべきポイントが多いので、手順を書き記しておきます。

How to install redis-cli and psql client on your machine with Docker

Preparing docker images

We will use minimalistic Linux distribution called Alpine (5MB)

Dockerfile of redis-cli

FROM alpine:latest
RUN apk --update add redis

Debug your PHP in Docker with Intellij/PHPStorm and Xdebug

For your local dev, create a Dockerfile that is based on your production image and simply install xdebug into it. Exemple:

FROM php:5

RUN yes | pecl install xdebug \
&amp;&amp; echo "zend_extension=$(find /usr/local/lib/php/extensions/ -name xdebug.so)" &gt; /usr/local/etc/php/conf.d/xdebug.ini \

	%matplotlib inline
	import matplotlib.pyplot as plt
	import numpy as np

	from matplotlib import animation as ani


	plt.figure(figsize=(8,8))
	n=20

	#!/usr/bin/env python3
	# encoding: utf-8
	"""Use instead of `python3 -m http.server` when you need CORS"""

	from http.server import HTTPServer, SimpleHTTPRequestHandler


	class CORSRequestHandler(SimpleHTTPRequestHandler):
	def end_headers(self):
	self.send_header('Access-Control-Allow-Origin', '*')

	#!/bin/bash --login

	# Cf. http://stackoverflow.com/questions/33041109

	# Xcode 7 (incl. 7.0.1) seems to have a dependency on the system ruby.
	# xcodebuild is screwed up by using rvm to map to another non-system
	# ruby†. This script is a fix that allows you call xcodebuild in a
	# "safe" rvm environment, but will not (AFAIK) affect the "external"
	# rvm setting.
	#

	import http.server

	server_address = ("", 80)
	handler_class = http.server.CGIHTTPRequestHandler
	server = http.server.HTTPServer(server_address, handler_class)
	server.serve_forever()
