Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

delete volumes

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm

In search of Idiomatic ESLint

I'm in the process of creating a new web app boilerplate, and I need to give it a lint config. Kyle Simpson convinced me I should look at ESLint instead of JSHint, so now I have to figure out how to configure ESLint to my liking. My liking means as idiomatic as possible.

To that end, I will give an unnamed JavaScript related prize (of real value) to the person who can show me an .eslintrc that most closely matches the idiomatic style I recommend in Appendix A of "Programming JavaScript Applications" (O'Reilly).

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

	#!/bin/bash

	# Add this script to your cloudformation directory (we have ours in the project root).
	# Then set up a build step in Team City that executes the custom script:
	#
	# [[ -f ./cloudformation/validate-cloudformation.sh ]] && ./cloudformation/validate-cloudformation.sh
	#
	# That way branches without the script will still build.
	#
	# Make sure your CI user has the following policy attached to it for AWS:

	#!/usr/bin/env bash
	# Usage: {script} [ OPTIONS ] TARGET VERSION
	#
	# TARGET Default target is "/usr/local".
	# VERSION If not defined tries to get the build into the Sublime Text 2 website.
	#
	# OPTIONS
	#
	# -h, --help Displays this help message.
