Install ImageMagick from source on Ubuntu 14.04

The version of ImageMagick that is installed when you run apt-get install imagemagick on Ubuntu 14.04 is older than I would like.

$ convert --version

# Running a single minimalistic unit test with Rails 4 and Ruby 2.1.1 is a lot faster
# if you avoid loading Rails:

# Running the test *with* Rails

time ruby -Itest test/models/my_model_test.rb # => real ~ 6s

# Running the test *without* Rails

time ruby -Itest/no_rails test/models/my_model_test.rb # => real ~ 0.6s

Getting Melvanimate to fly :-)

What is Melvanimate?

Melvanimate is a library for ESP8266 that lets you control your Neopixels over WLAN easily. It supports everything imaginable besides toasting your toast, e.g.,:

• Animate Neopixels (hence the name!) or set them to solid colors
• Control LEDs via a web interface (for casually setting a certain color of effect)
• Control LEDs via MQTT or DMX/E131 (for automation)
• Adalight DIY ambient monitor lighting similar to Ambilight
