tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

With Docker 1.8.0 shipped new log-driver for GELF via UDP, this means that the logs from Docker Container(s) can be shipped directly to the ELK stack for further analysis.
This tutorial will illustrate how to use the GELF log-driver with Docker engine.
Step 1: Setup ELK Stack:
- docker run -d --name es elasticsearch
- docker run -d --name logstash --link es:elasticsearch logstash -v /tmp/logstash.conf:/config-dir/logstash.conf logstash logstash -f /config-dir/logstash.conf
- Note the config for Logstash can be found at this link
- docker run --link es:elasticsearch -d kibana
Once the ELK stack is up now let's fire up our nginx container which ships its logs to ELK stack.

LOGSTASH_ADDRESS=$(docker inspect --format '{{ .NetworkSettings.IPAddress }}' logstash)
`docker run -d --net=host --log-driver=gelf --log-opt gelf-address=u

Auto-deploying built products to gh-pages with Travis

This is a set up for projects which want to check in only their source files, but have their gh-pages branch automatically updated with some compiled output every time they push.

Create a compile script

You want a script that does a local compile to e.g. an out/ directory. Let's call this compile.sh for our purposes, but for your project it might be npm build or gulp make-docs or anything similar.

The out/ directory should contain everything you want deployed to gh-pages. That almost always includes an index.html.

React (Virtual) DOM Terminology

In React's terminology, there are five core types that are important to distinguish:

ReactElement / ReactElement Factory
ReactNode
ReactComponent / ReactComponent Class

React Elements

	#!/usr/bin/env bash
	set -o errexit
	set -o nounset
	set -o pipefail

	# Automatically update your CloudFlare DNS record to the IP, Dynamic DNS
	# Can retrieve cloudflare Domain id and list zone's, because, lazy

	# Place at:
	# /usr/local/bin/cf-ddns.sh

	#!/bin/sh
	set -x
	set -e
	#
	# Docker build calls this script to harden the image during build.
	#
	# NOTE: To build on CircleCI, you must take care to keep the `find`
	# command out of the /proc filesystem to avoid errors like:
	#
	# find: /proc/tty/driver: Permission denied
