I wanted to know, "Do I need to learn about EventMachine or node.js? Can I use threads? What is so good or bad about threading in Ruby 1.8, Ruby 1.9, JRuby and Rubinius 2.0?" What was important to me was the the choice was abstracted away. I want...
We are probably all familiar with the dreaded edge cases that creep up on our production code and sucker punch it with inputs we never expected. I bet most of us have scrambled to fix those at one time or another. The good news is that you don't ...
We spend a large portion of our time thinking about code and technical project issues. What about the people side of things? The majority of project failures occur because of people, not technology. What we need are guides that help us navigate th...
Ever wonder how netflix can predict what rating you would give to a movie? How do recommendation engines get built? Well, it's possible with JRuby and it's fairly straight forward. Many engines are built purely on support vector machine regressio...
Choosing a data storage engine is an important decision, but it doesn’t have to be painful if you know the landscape. We’ll look at several DBMSs (and a few you’ve never heard of), compare and contrast them based on use-cases, and how to plu...
Are your methods timid? Do they constantly second-guess themselves, checking for nil values, errors, and unexpected input? Even the cleanest Ruby codebases can become littered over time with nil checks, error handling, and other interruptions whi...
Tired of maintaining your one-off script that has now become someone's job to execute? Wishing you could create polished applications on the command line similar to git or cucumber? In my talk, I'll talk about what makes a command line application...
This talk will dive into the details of OpenShift Express and it's support for Ruby and Rack. It will also cover how we are using Ruby internally on our development of OpenShift. This session will not only walk you through how to use OpenShift to ...
You are happily writing new code for your system when all of a sudden the code is not behaving the way you thought it should. Perhaps you just created a failing test, and the code you wrote was expected to make the test pass ... but it doesn't. Wh...

We are known for our community. Does this mean our job is done? Are we starting to stagnate? Simply gathering Rubyists together isn't enough. How are you improving your community? Fear not as anyone of you can take action. Whether you live in a pl...
On some teams, pairing is the norm, and some developers really enjoy the collaboration, experiencing enhanced productivity.Others work on teams where pairing is shunned, avoided, or... faked. I have been on a quest to discover, on the one hand, w...
Rails has been around for seven years now, which means there's been more than enough time for us to build huge, monolithic apps that do way too much. It's no surprise, then, that we've started to see a surge of interest in the decomposing large ap...
Everybody wants to do test-driven development, but switching to TDD or BDD on an existing project that doesn’t have tests presents special challenges. Often, the current code is a tangled mess of dependencies that defeats the very concept of uni...
Build features fast. Ship them. That's what we try to do at GitHub. Our process is the anti-process: what's the minimum overhead we can put up with to keep our code quality high, all while building features as quickly as possible? It's not just ...
Live podcast recording for Ruby Rogues!
If you’re writing code that looks like User.all.reject(), you’re doing it wrong. Don’t worry though, we’ve all done it before. ActiveRecord makes it all too easy to introduce code that is far from performant, and after awhile, we tend to f...
The sweeping changes brought on by Rails 3 and 3.1 haven’t just make our existing development patterns easier, they have opened up the ability for us to build new patterns that accomplish more in a more beautiful and efficient way. In this sessi...
There are many strange beasts in the Ruby language. Some of them you might never have seen. Others you might have seen but not understood. Ruby is a big language, and this presentation will show you some of the corners of Ruby that you might not ...
As developers, we want to minimize the time we spend fighting with our development environment. The less time we spend dealing with configuration issues, the more time we can spend doing what we do best... creating awesome apps! I show how you can...
