This runs a build for a small elixir (phoenix) project in about 40 seconds by caching as much of the compiled files as possible.

We've been using this for months in multiple projects without any issues. Please ping be if there is any issues with this script and I'll update it.

It should be generic enough to work on any elixir app using mix.

If you have a elixir_buildpack.config, then enable that section in the build script to keep versions in sync!

2016-08-09: Updated to newer Erlang and Elixir and fixed curl command.

###The ROSSConf project, or: helping Open Source help Open Source

Last April Saturday ROSSConf Vienna took place. Sixty registered participants, some loose canons, 5 projects, 6 maintainers, 8-ish team members, 1 baby all in one coworking space. Here's what happened.

####In the beginning October last year, at arrrrcamp, I came up with the concept for ROSSConf. Having attended 1001 tech conferences (I haven't kept count) I concluded that I'm always missing something. I found myself listening to a talk and wishing I could contribute to the project discussed but the internet connection wasn't sufficient for cloning the repo, nor was there time to hack on the project as the next talk was about to start. And, I figured, I'd need some time to get into the project and the contributing etiquette before being able to contribute.

1. Install Node.js

Follow the steps given here to install Node.js and NPM.
Verify whether NPM is installed by typing npm -v in a terminal window.

2. Install React Native CLI

npm install -g react-native-cli

3. Setup Android Development Environment

Download and install Android Studio as explained here.
Run Android Studio and open the SDK Manager. Under the SDK Platforms tab, check Show Package Details, expand Android 6.0 (Marshmallow) and check the following:

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

There are always 24 hours in a day.
February is always 28 days long.
Any 24-hour period will always begin and end in the same day (or week, or month).

How to build a JSON API with Elixir & Phoenix

Welcome! In this guide we'll go step by step to build an API with Elixir and the Phoenix Framework.

Note, i wrote this around 2017/18 so things might have changed. Also it's incomplete. Hopefully still useful. Yadayada.

Here's the plan:

Install Elixir
Create a new Phoenix project

	# Ask for the user password
	# Script only works if sudo caches the password for a few minutes
	sudo true

	# Install kernel extra's to enable docker aufs support
	# sudo apt-get -y install linux-image-extra-$(uname -r)

	# Add Docker PPA and install latest version
	# sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9
	# sudo sh -c "echo deb https://get.docker.io/ubuntu docker main > /etc/apt/sources.list.d/docker.list"

	#!/bin/sh

	# I use this to install Elixir on our codeship instances for testing. YMMV.
	# curl -O https://gist.githubusercontent.com/jamesotron/44f8962cddef781ab830/raw/e75599e95587cbca26e707505fd40dd0f26eb0f5/install_ex.sh
	# . ~/install_ex.sh

	# You can override your Elixir and Erlang versions from your shell when you call ./install_ex.sh.
	export ERLANG_VERSION=${ERLANG_VERSION:-18.0.3}
	export ELIXIR_VERSION=${ELIXIR_VERSION:-1.0.5}

	defmodule EctoBatchStream do
	import Ecto.Query, only: [from: 1, from: 2]

	@batch_size 1000

	# Example:
	#
	# query = from u in MyApp.User, select: u.email
	# stream = EctoBatchStream.stream(MyApp.Repo, query)
	# stream \|> Stream.take(3) \|> Enum.to_list # => […]

	require 'trackler'
	require 'uri'

	ORG_NAME = 'rossconf2018-exercism-track-id'.freeze
	CONFIGLET_PATH = '/Users/laura.feier/Downloads/configlet'.freeze
	HERE = Pathname.new(__FILE__).dirname.expand_path
	ORIGINAL_DIR = HERE.join('original').tap(&:mkpath)
	BRANCH_NAME = 'order-configs'.freeze

	Dir.chdir(HERE)
