Here I share the story of how I created a big bug and the lessons I learned from this experience. In hope that you can learn from them, so that when it happens to you (it eventually will), you are better prepared. Presented at: RubyConf 2017 This talk is based on a true story.

Imagine your work week ends after releasing a set of features to production. Your team is happy and you feel good about yourself. A call about a problem with payments wakes you up the next morning. You find out your most valuable users were charged hundreds of times, consuming their credit card limits, leaving others in overdraft. They're angry because they can't even buy milk at the store. Learn how a "perfect bug storm" caused the problem, how our processes failed to catch it and how hard it was to gain our users trust back.

Due to Ruby’s great abstractions we take most of the network related stuff for granted. We think we know how all of that works, but do we? Let’s go over the fundamentals together, learn about how Ruby models TCP Sockets and how we can make a good use of it.

Let's not sugar coat it. In this talk you'll learn about some where thing went terribly wrong, some of them involved loosing money. Stories of stuff that can easily get overlooked, about the most common mistakes when working with payments and things you probably won't consider until shit hits the fan. All of this so that you don't run into the same problems and don't have to learn those lessons the hard way.

Let's go over the fundamentals together, learn about how Ruby models TCP Sockets and how we can make a good use of it. Even if you're not doing network programming, being able to dive multiple levels to understand what's going on will give you a great advantage. The sort of concepts we'll go over this talk don't apply to Ruby only. All modern languages support the Berkeley Sockets API so this knowledge is portable and it will serve you for many years to come. During the talk we will go through the fundamentals of programming with sockets. This includes creating sockets, client and server life-cycle, reading and writing data, non-blocking IO and connection multiplexing.

Is there a pragmatic way of following them in our day to day jobs or are they just some principles a few computer scientists wrote? Fortunately there is, SOLID principles are not just good ideas , they are intended to help us write better code, enjoy our jobs more and be happy programmers. So, where should we start? We should start where we always do. By writing tests, yes, for real. As Kent Beck says "TDD doesn't drive good design. TDD gives you immediate feedback about what is likely to be bad design", so we need to go a step further. In this talk we will see how writing tests is not just doing TDD is about having good test coverage, it's also about driving our code towards good design, one that follows SOLID principles.
