Our code is full of hidden assumptions, things that seem like nothing, secrets that we did not name and thus cannot see.
These secrets represent missing concepts and this talk shows you how to expose these concepts with code that is easy to understand, change and extend.
Being explicit about ideas will make your code simpler, your apps clearer and your life better. Even very small ideas matter. Everything, even nothing, is something.
Background job processing is an important component of most large Rails applications. Two of the most common solutions - Resque and Sidekiq - are largely differentiated by one underlying architectural decision: processes or threads?
Is this talk, we'll provide a gentle introduction to threads and processes, and then crack open the Resque and Sidekiq gems to see how they work. Along the way, we'll learn a bit about concurrency at the OS and Ruby layers, and about how some of the tools we rely on every day are written.
