OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

smoil

class Account < ActiveRecord::Base

  def self.search(name = nil)
    # search logic
  end
  
end

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.

Requires:

• Homebrew (http://mxcl.github.io/homebrew/)

• Ruby

Verify Homebrew is not sick:

brew doctor

mxub

$iphone-portrait: em(320)         
$samsung-galaxy-portrait: em(380) 

$kindle-portrait: em(600)
$ipad-portrait: em(768)


// all landscape
$iphone-landscape: em(480)

  gem 'heroku-deflater'

  # Heroku injects it if it's not in there already
  gem 'rails_12factor'
