Simple automated deployment using git hooks

Here are the simple steps needed to push your local git repository directly to a remote (e.g. prod) server over ssh. This is based on Digital Ocean's Tutorial.

Overview

You are developing in a working-directory on your local machine, let's say on the master branch. Usually people push code to a remote server like github.com or gitlab.com and pull or export it to a production server. Or you use GitHub's webhooks to send a POST request to a webserver to take appropriate actions such as cloning/checking out a branch on the remote (prod) server.

IMPORTANT: Ignore the out-of-date steps below for getting Chromium keys.

Instead, read this up-to-date guide (Jan 2023) written by @LearningToPi.

P.S. Thank you to every contributor below who provided tips over the years on what should be a straightforward process: setting up Chromium for local development.

Long live the web!

This is the process of setting up erlang, rebar3, and cowboy for a Hello World, starting with a clean Debian 8 install.

Update apt and install deps:

root@046edcaea45a:~# apt-get update
root@046edcaea45a:~# apt-get install erlang erlang-dev gcc
root@046edcaea45a:~# wget https://s3.amazonaws.com/rebar3/rebar3
root@046edcaea45a:~# mkdir ~/bin/
root@046edcaea45a:~# mv rebar3 ~/bin/
root@046edcaea45a:~# chmod +x ~/bin/rebar3

Long Live CoffeeScript and Long Live ES6

Clearly ES6 is a huge improvement over ES5, and tools like [6to5][] allow us to use these cool features now. I was reading [Replace CoffeeScript with ES6][replace coffeescript] by [Blake Williams][] and thought it was a great summary of how ES6 solves many of the same problems that CoffeeScript solves; however I'd like to comment on a few of Blake's points and talk about why I'll be sticking with CoffeeScript.

Classes

Classes in ES6 (like many of the syntax changes in ES6) are very similar to the CoffeeScript equivalent. To support browsers that are not fully ES5 compliant (e.g. IE8-), however, we still can't really use getters/setters, so ignoring these the comparison is:

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

	Step 0: Download unetbootin and the latest nixos iso, put nixos iso onto unetbootin
	Step 1: On OSX, Resize your OSX partition using disk utility (leave 25% - 75% as free space)
	Step 2: Boot into NixOS from USB (hold down Alt-Option)
	Step 3: Use fdisk to create 3 new partitions (nixosswap ~10GB, nixoshome ~75GB, nixosroot ~20GB)
	Step 4: Init file systems / swaps
	# mkfs.ext4 -L nixosroot /dev/sda4
	# mkswap -L nixosswap /dev/sda5
	# mkfs.ext4 -L nixoshome /dev/sda6
	Step 5: Mount
	# mount /dev/sda4 /mnt
