Ansible is configuration management tool and remote orchestration tool. It's kind of like Puppet, and Fabric had a baby. It can get boxes into a desired state like Puppet, but it can also run commands on a bunch of remote boxes like Fabric. It has a few difference from puppet. Namely that it pushes its configuration on demand to boxes instead of having a puppet dameon periodically check for changes and reset things. It also is configured entirely through yaml files that run tasks, instead of having a DSL for managing state.
Ansible is broken down into three major parts. Inventory, Playbooks, and Roles. I will cover these three briefly. Anyone looking for a more in-depth documentation on ansible should checkout the docs.
An inventory is a document that describes all of the hosts you want to manage, and how they are grouped. Take a look at our master inventory to get a sense of the structure.

Defining a Ruby method that can accept either a block or a Proc as an argument1
Recently I was trying to refactor some code to make it more testable. The code I wanted to refactor was in a block. But, I wanted to be able to test the block code independently from the method that was using the block.

The person, one Mr Cuntis Yarvin, at the centre of the #lamdaconf debacle performed an Ask Me Anything on Reddit. One of his defenders on Twitter referenced this response from the AMA as proof that he was not racist.
I appreciate that giving more commentary space to this situation provides the oxygen that our protagonist craves. On the other hand I feel like this is sufficiently important to our community to stand up and defend those people that this person seeks to diminish and damage.
So, with that and a deep breath, let's take this response bit by bit and see whether it works out as a defence by the protagonist as evidence of his lack of racism.
Amusingly, my "one offensive comment" was actually me repeating something my wife (not at all a 'shitlady') learned in her MFA program at SF State (not at all a Hitler Youth academy). (This is the observati

I want to start off by saying that I strongly respect John De Goes and the decision he made. If you haven't already read his extensive post about what he did and why he did it, I highly recommend you take the time. His post is thorough and generally persuaded me to his way of thinking, which is not that the works of Moldbug should be accepted or ignored, but that we need to be inclusive of differing beliefs in a community, so long as the holder of those beliefs is willing to "leave them at the door". This is a strong, intellectually defensible and consistent position.
However, as the day has gone on, and I've discussed this issue at length with many members of the community. I have come to the conclusion that this is idealistic, and ultimately missing the point. And as strange as it seems, the point is not that there is a literal Neo Nazi who will be speaking at a well-regarded conference! The point is somehow bigger tha
