I think this is called Facebook Connect, but I've also heard the term Facebook Graph API, so I'm not sure which one I'm asking for.

What do I need to do in order to integrate Facebook Connect with Devise?

Solution:

This question is pretty old now. A year ago, Devise v1.2 introduced OmniAuth support. Now Devise is at v2.1 (as of this writing) and using OmniAuth is even easier. Here is a great tutorial from the Devise wiki on using the omniauth-facebook gem with Devise to allow sign-in using Facebook."

Beginning Rails 4 is a book that will guide you from never having programmed with Ruby, to having a Rails application built and deployed to the web. You'll learn how to combine all the components of Rails to develop your own web applications. You will use test driven development to make sure your application works exactly like you expect. You will learn how to use Git for source control and best practice techniques to create applications like a pro. Essential, and often-missed, information on testing and learning to program with Ruby are also covered. This book is well suited for someone with little to no Ruby or Rails experience, or possibly even someone with no experience developing web applications at all. Beginning Rails 4 does assume a basic familiarity with the web and typical web terms, but doesn't require you to be an expert of these."

Do those air purifiers / ionizers really work? Is it really genuine science at work here?

Do those air purifiers / ionizers really work? Is it really genuine science at work here?: "Most reviews agree that those with severe allergies, asthma and bronchitis -- who need to control indoor air quality as much as possible -- may benefit the most from air purifiers, but only when used in conjunction with other allergen source-control strategies, including ventilation and daily HEPA vacuuming. These reviews say there’s little evidence that air purifiers are effective alone. The Allergy and Asthma Network/Mothers of Asthmatics takes this stance: "Air filters don’t replace the need for eliminating or reducing indoor allergens. Beware of any manufacturer making health claims.""

Using Git and GitHub with Rails. Git provides a source control repository. Use Git to roll back code changes as needed, when you are collaborating with others, and when you must deploy an app for hosting with a service such as Heroku. Get a GitHub account for remote backup and collaboration.

If you are building a throw-away app for your own education, you may decide not to use Git, but sooner or later you will need to learn to use Git to participate in the open source community. Git is not easy to understand or learn (see a discussion) but it is a worthwhile and essential tool for software development."

Setting up Sublime Text 3 for Rails Development | The K Unit

Setting up Sublime Text 3 for Rails Development | The K Unit: "When I started programming, IDEs were the norm. I spent much of my time using tools like Microsoft Visual Studio and got very used to features like Autocomplete. However, that also meant I needed to have access to MSDN which for a young professional was very expensive if you wanted to develop on your own dime and time. IDEs also tend to be very prescriptive and require a lot of overhead"

Install Ruby on Rails · Ubuntu Linux · RailsApps

Install Ruby on Rails · Ubuntu Linux · RailsApps: "Don’t Install Ruby from a Package
Ubuntu provides a package manager system for installing system software. You’ll use this to prepare your computer before installing Ruby. However, don’t use apt-get to install Ruby. The package manager will install an outdated version of Ruby. And it will install Ruby at the system level (for all users). It’s better to use RVM to install Ruby within your user environment."

readability - How to determine if a programming language is verbose or terse? - Programmers Stack Exchange: "Verbose means lots of symbols. Terse means fewer symbols.

This has nothing to do with ease of reading or ease of understanding.

Some folks find verbose COBOL easy to read, other find it confusing because so many symbols are required to do so little.

Some folks find terse I/J/K and APL easy to read because the program is very short. Others find it hard to read because the symbols are obscure.

Terse/Verbose has no relationship with easy to read or easy to understand."

What Does &amp; Mean? | FSDeveloper: "While Ron is "technically correct," I'm assuming that you simply wanted to know the following:

& is just the "full way" of writing the "&" symbol...

(Hint: the symbol is called an "ampersand" or "amp" for short!)
