📂 Minimize allocations in Go

Working with protobuf in Go puts significant load on the memory subsystem, as protobuf-generated structures often contain a significant amount of pointers.

One way to minimize the number of allocations is to allocate all the fields at the same time, and then use internal pointers to wire them up.

Let's pretend you have (the generated Go code for) four messages A, B, C, and D (note: for clarity this is not really protobuf-generated code, but the technique

A good commit message looks like this:

	Header line: explaining the commit in one line

	Body of commit message is a few lines of text, explaining things
	in more detail, possibly giving some background about the issue
	being fixed, etc etc.

	The body of the commit message can be several paragraphs, and
	please do proper word-wrap and keep columns shorter than about

##Working with ansible-vault

I've been using a lot of Ansible lately and while almost everything has been great, finding a clean way to implement ansible-vault wasn't immediately apparent.

What I decided on was the following: put your secret information into a vars file, reference that vars file from your task, and encrypt the whole vars file using ansible-vault encrypt.

Let's use an example: You're writing an Ansible role and want to encrypt the spoiler for the movie Aliens.
