I'm a fan of MiniTest::Spec. It strikes a nice balance between the simplicity of TestUnit and the readable syntax of RSpec. When I first switched from RSpec to MiniTest::Spec, one thing I was worried I would miss was the ability to add matchers. (A note in terminology: "matchers" in MiniTest::Spec refer to something completely different than "matchers" in RSpec. I won't get into it, but from now on, let's use the proper term: "expectations").

Understanding MiniTest::Expectations

Let's take a look in the code (I'm specifically referring to the gem, not the standard library that's built into Ruby 1.9):

# minitest/spec.rb

module MiniTest::Expectations

Remove recursively zombie containers

In e.g.: you 'docker run -t -i' a 'bash' session and '.bashrc' is fucked up, container will forever respawn disallowing you to 'docker rmi' the used image .

docker rmi triangle/ubuntu-saucy-with-rvm 2>&1|grep ^Error|awk '{print $10}'|xargs docker rm

# Knife Configuration File.
#
# This is a Ruby DSL to set configuration parameters for Knife's
# general options. The default location for this file is
# ~/.chef/knife.rb. If multiple Chef repositories are used,
# per-repository configuration files can be created. A per repository
# configuration file must be .chef/knife.rb in the base directory of
# the Chef repository. For example,
#
#     ~/Development/chef-repo/.chef/knife.rb

Server Status Squares

A Dashing widget that checks whether a server is responding to either an http or ping request using smaller squares to represent its status.

This is based off of the Server Status widget that willjohnson developed but modified to work across multiple squares rather than be one square with a list.

Description

The widget updates the appropriate squares color upon determining its status. Statuses are as follows:

# FIRST: Environment variables
knife_env         = ENV['KNIFE_ENV']
knife_org         = ENV['KNIFE_ORG']
knife_config_dir  = ENV['KNIFE_CONFIG_DIR']
knife_config_file = ENV['KNIFE_CONFIG_FILE']

if knife_env.blank?
  `git branch 2> /dev/null` =~ /^\*\s(.*)$/
  git_branch = $1

Ubuntu 12.04, Ruby, Rails, Nginx, Unicorn and git-deploy

In the seemlingly endless search for the actual correct and easy way to deploy a Rails app, we have tried several ways. We tried out using Apache2 and running a cluster of Thin servers. With the built in threading of Puma we decided to use it with Nginx.

Server Setup

• Create new server
• Login to new server
  • ssh root@IPaddress (you can also use the domain name if you have the DNS setup already)
  • accept the RSA key
