Different services I can suggest when a non-tech friend or family member asks me how they can cheaply make a website and possibly use it to sell stuff online.

My issues with Modules

In researching topics for RailsCasts I often read code in Rails and other gems. This is a great exercise to do. Not only will you pick up some coding tips, but it can help you better understand what makes code readable.

A common practice to organize code in gems is to divide it into modules. When this is done extensively I find it becomes very difficult to read. Before I explain further, a quick detour on instance_eval.

You can find instance_eval used in many DSLs: from routes to state machines. Here's an example from Thinking Sphinx.

class Article &lt; ActiveRecord::Base

Expectations

I took the ideas presented here and built a gem called Mustard. Check it out!

There are several expectation/assertion interfaces available for writing tests/specs. Here are some issues I have with them.

Test::Unit/MiniTest

The order of assert_equals feels backwards
Oh wait, that should be assert_equal (that too)

Basics

Create controller

php artisan make:controller NameOfTheController --plain

Connect to Homestead VM

Vagrant Setup

This tutorial guides you through creating your first Vagrant project.

We start with a generic Ubuntu VM, and use the Chef provisioning tool to:

install packages for vim, git
create user accounts, as specified in included JSON config files
install specified user dotfiles (.bashrc, .vimrc, etc) from a git repository

Afterwards, we'll see how easy it is to package our newly provisioned VM
