Ever want to write an App that uses the Facebook graph? You could be the next Zynga, Foursquare, or Causes; but first
you need to create your app. This quick demo shows getting started by generating an app through Facebook and then editing
it. If you’ve already got a working web app it’s simple to add Facebook functionality to it, though
we’ll save that for another day. What are you waiting for, five minutes from now you could have your very own
live Facebook App!
Starting today Heroku will allow you to specify a version of Ruby in your
production app. As one of the most requested features we have been asked for time and time again, we’re happy to
announce that it’s now live. To get started you’ll want to update your version of Bundler locally to
version 1.2.0, or above.
Wicked was featured by Ryan Bates on Railscasts this past week. I’ve learned quite a bit over the years from Railscasts, so it’s a great honor to have my work featured there.
The cats out of the bag, Ruby isn’t immune to legacy code problems. Just because your app is written in a hip,
fun, and dynamic language doesn’t mean that your codebase can’t stagnate, bloat, and quickly turn into an
unmaintainable ball of mud. Before Gowalla was purchased by Facebook, the Rails code
base stood at close to seven thousand files, with the largest model clocking in at around 3,500 lines of code. While
we were somewhat unique, being originally written in Merb and then ported to Rails, applications of this size
aren’t all that uncommon. If you’ve got a large app there are a number of things you can do make your
situation better, one of the simplest with the greatest impact is splitting up models into concerns.
My good friend @mattt just released this great tutorial for creating an iOS Photo-Sharing app on Rails. You should hop, skip, or jump on over to the article now. What are you waiting for?
Right out of the gate, Ruby gives us some powerful ways to re-use instance and class methods without relying on
inheritance. Modules in Ruby can be used to mixin methods to classes fairly easily. For example, we can add new
instance methods using include.
This question comes up a lot, people want to have an object, lets call it a Product that they want to
create in several different steps. Let’s say our product has a few fields name, price,
and category and to have a valid product all these fields must be present.
Haven’t you always wanted to make some changes to your server and then absolutely slam it with traffic to see the result? Thats pretty much what I did last week while writing how to Super Charge your Rails App with Rack Cache, using the BlitzIO tool.
Slow is sweeping the nation: slow food, slow living, and slow reading. Unfortunately your app called, it said it
wants to be fast. Web apps that respond quickly are more enjoyable to work with and Google even gives them a small SEO
bump. Recently basecamp
next got quite a bit of customer love based on how quickly it responds. The fact of the matter is if it’s
on the web, fast matters.
