/**
 * Try to acquire an arbitrarily-named lock by binding a Unix
 * (family AF_UNIX) datagram (type SOCK_DGRAM) socket to an
 * abstract address corresponding to the lock name. On success,
 * the bound socket resource is returned (or null, on
 * failure). You may either call unlock() with that resource to
 * release the lock explicitly, or rely on the operating system
 * to clean up the socket when the process exits.

Managing OpenStack instances with Ansible through an SSH bastion host

I'm be using DreamCompute as my OpenStack provider, but there are dozens to choose from. I assume you already have Ansible and the OpenStack CLI tools installed.

Motivation

With the proliferation of OpenStack public clouds offering free and intro tiers, it's becoming very easy to effectively run a simple application for free or nearly free. Also with the emergence of Ansible, you don't need to learn and deploy complicated tools to do configuration management.

Vim + Eclim + Scala

WARNING! Do not install anything from update sites before installing Eclim! This is because Eclim determines available project natures (android, scala, etc) by trying to discover them at install time. If they are installed on a per-user basis, it won't find them. If you're installing Eclim for use with an existing Eclipse install

You're also better off not to install any plugins via your package manager. Eclim will give you the option to install plugins associated with each project nature from its install wizard.

Install Eclipse Luna. On Arch Linux, it's available in extra.

pacman -Sy eclipse

Can I make a game in a Gist?

I'll write the world in YAML first, and write the code to stitch it together last.

Maybe I can use Mermaid to draw the map.

Install Virtualbox, Vagrant and Ansible.

Create a new directory for your first Vagrant VM. In that directory, create a Vagrantfile using vagrant init, and enable the Ansible provisioner by adding the following.

config.vm.provision "ansible" do |ansible|
  ansible.playbook = "playbook.yml"
end

Now you can create an Ansible playbook named playbook.yml file in the same directory as your Vagrantfile, and vagrant provision will run it. Here's an easy one to start with that will update NSS and add the EPEL and IUS repositories.
