Chapter 1. Basics

Ruby style programming was built on two simple ideas:

Code must be crystal clear
Code must be concise

Example:

RSpec Intro

RSpec is a testing framework widely used along Ruby projects. Its paradigm is contained within the Behavior Driven Development (BDD) context, so it can be used to define internals and externals aspects of Ruby web applications. However, most developers see its major use for unit testing within the BDD context.

##Philosophy

Clarity X Cleverness

Always regard clarity over cleverness in your specs. This approach is based on the fact that, when you practice Test-Driven, you should make clear what are the intentions of the code that you are writing not just for you, but for others that are collaborating on the same project. Besides, a clear spec contributes as a documentation of the internals aspects of the project.

A modest alternative to DCI that might be worth further thought

One of the problems with advancing the discussion on DCI is that we lack a comparable alternative pattern that has the same goals, but favors a low ceremony approach. The closest thing we have to that is Rails concerns, but they are more like distant relatives of the DCI concepts rather than first cousins, and that makes comparisions between the two approaches not especially fruitful.

I am considering the idea of experimenting with my own paradigm that captures the intent and purity of DCI, but with the convenience of concerns. Please note that this is just the starting point of a conversation, it is NOT a promise of comercially available cold fusion or a cure for cancer. It's just a gist with an idea on it I'd like to hear your thoughts on.

What if we had a top-level topology that was split into Models, **Rol

Getting Started with NPM (as a developer)

If you haven't already set your NPM author info, now you should:

npm set init.author.name "Your Name"
npm set init.author.email "[email protected]"
npm set init.author.url "http://yourblog.com"

npm adduser

Signing VirtualBox Kernel Modules

These are the steps I followed enable VirtualBox on my laptop without disabling UEFI Secure Boot. They're nearly identical to the process described on [Øyvind Stegard's blog][blog], save for a few key details. The images here are borrowed from the [Systemtap UEFI Secure Boot Wiki][systemtap].

Install the VirtualBox package (this might be different for your platform).
