Ruby, OAuth, and Chrome Web Store

The Chrome Web Store, launching by the end of 2010, integrates a streamlined payment system, powered by Google Checkout. Your apps can opt-in to use this payment system for quick and easy payments. You can check if a user has paid for the application with a call to the Chrome Web Store License API.

The License API is a REST service which returns a simple JSON format, indicating if a user (identified by a Google Federated OpenID URL) can access your web app.

For Ruby developers, a new OAuth library, Signet, has recently been released which makes signing your OAuth request to the License API very easy.

The first step is to publish a paid web app to the Chrome Web Store. I've written a Quick Start Guide for the Chrome Web Store that will make this fast and easy. Once you configure your app as paid, either via a one time payment or a monthly or yearly subscription, you will be provided with an OAuth Token and Token Secret.

The second step is to install the Signet gem, as simple as gem install signet

Here is the sample code:



An example JSON response:

Looking forward to your web app in the store!

Lists and arrays in Dart

(This is Part 3 in a series about Dart. Check out Part 2, Function in Dart .) Warning : We expect the Dart libraries to undergo potentially sweeping changes before Dart goes to alpha. This document is relevant as of 2011-12-22. Intro Dart is a "batteries included" effort to help app developers build modern web apps. An important "battery" is the bundled core Dart libraries, providing common and rich functionality. Dart is building a solution for large, complex web apps, and providing well tested, integrated, and common libraries is key to helping a web app developer be more productive out of the box. The Collection libraries are a crucial set of APIs that Dart developers get for free. Much more than simple arrays and maps, the Collection library includes standard ways to filter, iterate, inspect, compose, and sort your data. This post specifically looks at List<E> , Dart's ordered, indexable collection of objects. Aside: The Dart project is lucky...

Converting Array to List in Scala

Now, this has to have a built-in somewhere in Scala , because it just seems too common. So, how to convert an Array to a List in Scala? Why do I need this? I needed to drop to Java for some functionality, which in this case returns an Array. I wanted to get that Array into a List to practice my functional programming skillz. **Update**: I figured out how to convert Arrays to Lists the Scala way. Turns out it's a piece of cake. val myList = List.fromArray(Array("one", "two", "three")) or val myList = Array("one","two","three").elements.toList The call to elements returns an Iterator , and from there you can convert to a List via toList . Nice. Because my first version wasn't actually tail recursive, what follows is a true tail recursive solution, if I were to implement this by hand. The above, built in mechanism is much better, though. object ArrayUtil { def toList[a](array: Array[a]): List[a] = { d...
