`groupby` and `countby` for python

Python has the standard methods for applying functions over iterables, viz. map, filter, and reduce.

For example, we can use filter to filter some numbers by some criterion:

even = lambda x: x % 2 is 0
odd  = lambda x: not even(x)
data = [1, 2, 3, 4]

こんにちは。今回は現実逃避を兼ねて Jade の素晴らしさをお伝えしたいと思います。

[Jade][0] は JST (JavaScript Templates) の一つであり、HTML を書くための[軽量マークアップ言語][1] である [Haml][2] に影響を受けた JavaScript テンプレートエンジンでもあります。

	(function(document, EventTarget) {
	var elementProto = window.Element.prototype,
	matchesFn = elementProto.matches;

	/* Check various vendor-prefixed versions of Element.matches */
	if(!matchesFn) {
	['webkit', 'ms', 'moz'].some(function(prefix) {
	var prefixedFn = prefix + 'MatchesSelector';
	if(elementProto.hasOwnProperty(prefixedFn)) {
	matchesFn = elementProto[prefixedFn];

	task :compile do
	`pandoc -t slidy -s edtech_cto_night.md -o slide.html`
	end

	task :open do
	`open slide.html`
	end

	task :watch do
	require 'listen'

	I think it's better to install javascript/css libraries using Bower rather than gem which is Ruby packager.

	1. Install Rails 4 and create a new project.

	2. Install bower(Note you need to install node first.)
	sudo npm install -g bower

	# This is a snippet to add to middleman's config.ru file if you want to add basic auth to your middleman app on heroku
	# NOTE: you need to stick this above the build script like shown below

	use Rack::Auth::Basic, "Restricted Area" do \|username, password\|
	[username, password] == ['username', 'password']
	end

	# This part below is just what builds the static site. you only need to add lines 4 - 6 above any build command like shown below.
	use Rack::TryStatic, :root => "build", :urls => %w[/], :try => ['.html', 'index.html', '/index.html']
