Or how to execute JavaScript from CSS in MSIE11 without using Scripts

Stop! This text is only interesting for you if you...

Like popping alerts in weird situations
Miss CSS expressions as much as we do
Have an unhealthy obsession for markup porn

Making Bookmarklets

I'm feeling very clever. I've got this sweet line of javascript that replaces "cloud" with "butt". My mom would LOVE this, but she doesn't computer very well. I'm afraid to show her the Developer Console and have her type/paste this in. But she IS pretty good at bookmarks, she knows just how to click those!

A bookmark normally takes you to a new web page. A bookmarklet is a bookmark that runs javascript on the current page instead of taking you to a new page. To declare that it is a bookmarklet, the "location" it points to starts with javascript:.

	LOVE_BIN=/usr/bin/love
	LOVE_DIR=./src/love
	DIST_DIR=./src/dist
	PATCH_DIR=./src/patch
	BUILD_DIR=./build
	BIN_DIR=./bin
	LOVE_VERSION=0.9.1

	GAME_NAME=MySampleGame
	PRETTY_NAME=My Sample Game

	#!/bin/bash
	echo ECS_CLUSTER=your_ecs_cluser_name > /etc/ecs/ecs.config

	INSTANCE=$(curl -s http://169.254.169.254/latest/meta-data/instance-id)

	hostname $INSTANCE
	sed -i.bak "s/\\(HOSTNAME=\\).*/\\1$INSTANCE/" /etc/sysconfig/network

	# https://aws.amazon.com/blogs/compute/using-amazon-efs-to-persist-data-from-amazon-ecs-containers/
	yum -y install jq

	(* type-level recursion with fold/unfold *)

	(* $ eff --effects -l rectypes.eff *)

	(* there's an unique isomorphism between fold and unfold such that:

	fold :: ...1 Unfix (...2 Fix (func) ...3) ...4 <=> ...1 Fix (func) ...4 :: unfold
	where func = \fix -> ...2 fix ...3

	so, conceptually:

	# Install our dependencies
	$ pip install -r <(wget -O- http://bit.ly/ssh_test_requirements)


	# Generate key pair without password
	$ ssh-keygen -t rsa -C "user@unicorn"
	Generating public/private rsa key pair.
	Enter file in which to save the key (/home/alex/.ssh/id_rsa): user.key
	Enter passphrase (empty for no passphrase):
	Enter same passphrase again:
