Jim performs a live programming exercise, doing a code kata for a Roman Numerals Calculator. Jim then walks us through some of the decisions he made and gives some great tips about TDD, complexity, and refactoring that we can apply in our daily programming.
Newcomer or seasoned veteran looking to get involved with Ruby documentation? We'll show you it's not as scary as it may seem, and there's plenty of ways to help. It's important to give back to the open source community and improve things for future developers. This talk will teach you the value of open-source, the benefits of contributing, and a little bit about how ruby-core works. You will learn what to look for when spotting documentation bugs in the MRI source code. We will cover the guidelines to writing MRI documentation, and how to submit a patch. Including helpful tricks using ri and rdoc. Zachary Scott is a Ruby committer since September 2012 who will gladly help with your first patch into ruby-core.
Patrick Robertson tells us about 5 of his favorite gems at the Boston Ruby February 2013 project night. Patrick also gives us tips on how to evaluate gems and determine which is the best for your needs. Patrick's picks are:
Jeremy Weiskotten tells us about 5 of his favorite gems (plus a bonus 6th gem) at the Boston Ruby February 2013 project night. Jeremy's picks are:
binding_of_caller (bonus gem)
Mark Bates takes us on a tour of he singleton pattern, one of the most common design patterns in any language. We'll take a look at how, and when, to implement singletons Ruby. We'll also learn what happens when you call '.new' on a class.
Atomic Commits: a scalable git workflow that provides a flexible alternative to test-driven development and ensures thorough code coverage, enforces a navigable commit history, and encourages developers to improve how they write code.
Storm is a free and open source distributed realtime computation framework. It
provides a clean, declarative abstraction for streaming computations. It's
durable, reliable, and simple to scale.
Some use cases of Storm include realtime analytics, online machine learning,
continuous computation, distributed RPC, and ETL.
You'll learn the basic ideas of Storm, and how RedStorm makes it easy to write
Storm topologies in Ruby.
Ruby 2.0 will start applications in less than half the time taken by 1.9.3. We'll see the techniques I used to diagnose (and fix) the problem, which can be used for any performance problem in MRI or a C extension.
Full text search isn't a simple problem, scaling a full text search solution when your app has do handle a couple million documents isn't simple either. In this talk I'm going to show you how you can easily integrate ElasticSearch into your Rails (or Ruby) application, common techniques for indexing and searching your data, sharding, fail over and scaling your solution to meet the scaling needs of today's applications.
Pascal Rettig will discuss what tools you can use to quickly build dynamic prototypes using Rails with the minimum amount of ceremony. He will talk about what tools (including Twitter bootstrap, Inherited resources, MongoDB and Backbone) you can use to accelerate the prototyping process on both the client and server side to get attractive, functional rails apps up and running quickly. The presentation will include live-coding where a simple app is bootstrapped, built and deployed to Heroku.
If you find yourself as a diligent Rubyist in a situation where you need to do some 'heavy lifting', or perhaps you have a computation that is just too painfully close to the lower end of your speed threshold, you may be in position that requires you to get closer to the metal. Writing Ruby extensions in C is probably a lot simpler and more fun than you may think. So let's learn how!
Location based apps are everywhere, but few developers have taken
their code beyond dropping a few pins on a map. Or embedding a Google
map. This talk begins by covering the different types of
location-based applications. Then we will look at the anatomy of a
typical location-based application, and the elements of the spatial
tool stack that apply to each geospatial element in the application.
Finally, we will explore some examples of geospatial applications that
are 1) inspiring and 2) use different elements of the stack as
discussed during the session.
We will wrap up with a preview of geo_rails, the soon-to-be-released
spatial framework for Rails.
Peter Jackson is a mountain climber, rails developer, project manager,
and musician from NH. Not a movie director.
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!
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.
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
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.
