Patterns of Enterprise Application Architecture

By Martin Fowler (2002)

Chapter 1: Layering

A basic example of layering: FTP < TCP < IP < Ethernet

Benefis of layering:

• You can understand a layer without knowing much about the others.
• Minimize dependencies.

Call the api client like this:

	var client = new ApiClient<SEnvelope>("https://baseurl.com/api/v1");
	//you would overload and add an auth_token param here 
 	client.GetDtoAsync("envelopes", "object_id", (response) => //callback
                                                          {
                                                              this.SEnvelope = response.Data;//should be an envelope from the server
                                                          });

When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.

To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.

What to expect

Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.

@user.errors[:username].should include("can't be blank")  # check for the error message

Prereq:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh
