Repurposing the Rails CLI
The Rails CLI works great for the vast majority of us, but what do you do when it doesn't? At MongoDB, we recently wanted to add a tighter integration between Rails and Mongoid (our ODM), and were able to create our own CLI tool that extends the Rails CLI, overriding the pieces that weren't compatible or relevant and extending it with the functionality we wanted.
I'll show you how we did it, and how you can do it yourself.
Flattening Recursion with Fibers
We used Ruby's fibers at MongoDB to unwind a recursive algorithm and execute it horizontally, without the stack overhead of recursion.
"Hang on," you might be thinking. "I thought fibers were a concurrency primitive?"
You're not wrong!
In this presentation, we'll summarize the problem we encountered while working with recursive callbacks, and give an overview of fibers in Ruby. Then, we'll put the two together and show you exactly how we ended up using fibers to solve an issue that was completely unrelated to concurrency.
