Enabling multicast DNS (mDNS) on a server allows other hosts on the local network to address the server as <hostname>.local.

mDNS is disabled by default in Ubuntu Server:

$ resolvectl mdns
Global: no
Link 2 (eno1): no

Idiomatic React Testing Patterns

Testing React components seems simple at first. Then you need to test something that isn't a pure interaction and things seem to break down. These 4 patterns should help you write readable, flexible tests for the type of component you are testing.

Setup

I recommend doing all setup in the most functional way possible. If you can avoid it, don't set variables in a beforeEach. This will help ensure tests are isolated and make things a bit easier to reason about. I use a pattern that gives great defaults for each test example but allows every example to override props when needed:

Using boot2docker and AnyConnect at the same time

Boot2Docker works great, so does AnyConnect but running the two together causes traffic intended for Boot2Docker to head down the VPN link, this ruining everything.

Investigation

Tale a look at what network your Docker VirtualBox VM is on:

tastle@TASTLE ~ $ env | grep DOCKER_HOST
DOCKER_HOST=tcp://192.168.59.103:2376

ANNOUNCEMENT

I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!

OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

	##
	# first run `brew install terminal-notifier`
	# then save this file in your home directory
	# and source it in your env file
	# e.g if you're using zsh, you'd add this in your .zshrc:
	# source $HOME/make-rake-talk.sh
	#
	# Restart your terminal and you no longer need to keep
	# staring at the screen when you're doing long ass rake tasks
	#
