The 4.0 release of Ruby on Rails is right around the corner. I'm going to
highlight some of the new features and changes in the newest version of Rails,
as well as features that will be removed or deprecated in Rails core.
More than any other feature of the language, in my opinion blocks are what make using Ruby fun. But what is a block, exactly? What would I see if I could cut one open and look inside? During this talk we’ll:
* Explore Ruby’s internal implementation of blocks, lambdas, procs and bindings.
* Learn how closures and metaprogramming are related in Ruby internals.
* Discover what metaclasses and singleton classes are and how Ruby uses them.
Do you really need to know how Ruby works internally to be a good Ruby developer? Probably not. But taking a peek under the hood can help you better understand the language… and is a lot of fun!
Most developers know enough about refactoring to write code that's
pretty good. They create short methods, and classes with one
responsibility. They're also familiar with a good handful of
refactorings, and the code smells that motivate them.
This talk is about the next level of knowledge: the things advanced
developers know that let them turn good code into great. Code that's
easy to read and a breeze to change.
These topics will be covered solely by LIVE CODING; no slides. We'll
boldly refactor during the talk, and pray the tests stay green. You
might even learn some vim tricks as well as an expert user shows you
Are you like me? Have you tried iOS development only to run away screaming in terror because of xCode, Objective-C, or many of the other absurdities that await you down the dark path to the top of the iTunes App Store?
If so, come with me as we explore RubyMotion. RubyMotion let’s you write native iOS in Ruby. But what does that mean? What does it look like? Do I still have to use xCode? What about those bizarre function definitions that Objective-C uses?
We will look at all of those questions, and more. By the end of this talk you will been presented with a high-level view of RubyMotion, what it is, and what it isn’t. I’ll show you the pros and cons of this potential unicorn of mobile application development.
Let’s explore this fascinating new development environment together and find out if it’s worth the price of admission.
If you get the fundamentals right, the rest of Ruby falls into place nicely. In this talk, Ruby developer and author David A. Black takes you on a tour of a large handful of Ruby features and techniques chosen to help you understand the essence of the language, and to avoid common pitfalls that sometimes hold people up when they're trying to master Ruby. All are invited: nubies, Rubyists who want to cement the foundations, and anyone who works with Ruby developers and wants to help them along the way.
YARD is a pretty great tool for writing and serving documentation. But did you know you could also do some other neat things with your documentation tool? This talk will outline some of YARD's lesser known features and discuss different commands and techniques to visualize your code, provide basic code metrics, and ensure overall quality in your documentation.
TorqueBox is a new kind of Ruby application platform that integrates popular technologies such as Ruby on Rails, while extending the footprint of Ruby applications to include built-in support for services such as messaging, scheduling, and daemons.
TorqueBox provides an all-in-one environment, built upon the latest, most powerful JBoss AS Java application server. Functionality such as clustering, load-balancing and high-availability is included right out-of-the-box.
Once a Rails application leaves the tender embraces of the development environment, it's an entirely new set of pitfalls and dangers to navigate. The care and feeding of a budding Rails application as takes its first steps into the wilds of the internet requires patience, dedication, and the most importantly: love.
At Rails Machine, we've been able to thrive while managing and operating hundreds of Rails applications. I'll be talking about exactly what 'Rails Deployments and Operations' means and how it relates to The Business (HA HA!). I'll also outline with some pragmatic principles and guidelines, and see how we can apply them to a selection of operational topics.
Deployment, hosting, configuration management, monitoring, and lots of other nouns.
Intended for developers new or veteran, who would like to contribute to open source but aren't sure how to start. Luke will talk about a few of the basic obstacles (in your head) to getting involved and how to deal with them, as well as the basic mechanics of pull requests and code reviews using Github. At the end of this talk you'll be ready to make the first commit, which is always the hardest.
Too many Rails developers incorrectly use and abuse the lib/ directory. I will demonstrate the importance of maintaing conventions in the lib/ directory that conform to what Rubygems is expecting, some "gotchas" if you are not careful, and a pattern I have been using to extract non-application specific code into the lib/ directory as a jumping off point to then eventually extracting that code as a Rubygem
Don't test your validation implementation! ValidAttribute is a new take on how you should be testing your model attribute validations.
Stasis quickly allows you to expose a directory and its assets to a browser
