Data Serialization Formats

JSON, MessagePack, and Google's Protocol Buffers are all awesome. Here's how they're awesome on different client environments and how to use them on your rails env.

Unionize: network superpowers for your docker containers

Unionize lets you connect together docker containers in arbitrarily complex scenarios.

Note: I recommend to use https://github.com/jpetazzo/pipework instead.

pipework is a better name than unionize
it's hosted on a "real" github repo instead of a small gist :-)

Now if you want Unionize, it's still here. Just check those examples.

Let's look at what happens when you do something like this inside of a view:

<%= render partial: 'some_partial' -%>

To render a partial, Rails has a helper method inside of Action View. The render method serves as a delegator and takes its input arguments and provides them to the view_renderer object.

The view_renderer object is initialized when ActionView::Base is initialized and is of the ActionView::Renderer class. This class performs all of the rendering that is necessary inside of the views. The design pattern of delegating to an object is used. When you call view_renderer.render, you are asking the view_renderer object to delegate the arguments of your call to another more specific object.

	# DreamHost Web Log Archiver
	#
	# DreamHost only stores web logs for a few days (configurable 3-30 days),
	# so to maintain long term logs, an archive copy must be maintained.
	#
	# This script copies new gzipped http/https log files from logs/ to
	# logs_archive/
