Victor Zagorodny 

Topic: “Monads in Ruby

Victor Zagorodny
Victor Zagorodny

Monads are mentioned more and more often in various talks, and discussions, but mostly about pure functional languages and... JavaScript. We are going to take a closer look on what monads are, in what typical use-cases they can be applied to make our code elegant and our life simpler. Also we’re going to review the current state of monads support in Ruby community and put our two cents in this.

I am a Senior Ruby developer and a tech lead @ Sloboda Studio, write mostly in Ruby, have passion for Haskell and pure functional programming in general.

Marek Piasecki

Topic: “# UDD - kicking of Understanding Driven Development

Marek Piasecki
Marek Piasecki

This presentation will be a natural continuation of Odessian # Hype Review. Thanks to your questions and feedback I’ll try to give some answers. I do believe deep understanding is a key thing in development. It’s kind of obvious. But we go further and further with reducing scope of our specializations.  We’re learning how to use tools and methodologies instead of learn in the first place how to program.

Marek Piasecki

Damir Zekic

Topic: "A Toolbelt of a Seasoned Bug Hunter"

Damir Zekic
Damir Zekic

Loud bugs are easy to spot and easier to fix. But there are subtle bugs that work over time and only in specific environments. Finding and fixing them is often a frustrating process. This talk will cover a debugging odyssey through which we will explore and evaluate various tools that can be used for better understanding what is happening in any application.

Damir Zekic

Sixteen years ago Damir started developing web applications with PHP, but switched to C#/ASP.NET (he tries not to remember those few projects he was forced to implement with VB.NET) until he saw the radiant shine of Ruby. Developing web apps for the majority of his career as a software developer, he’s proficient with both back-end and front-end work, but recently started to focus on the back-end more. Enthusiastic about functional programming. He is also a part of Speakers Network in Toptal.

Tetiana Chupyra

Topic: "Microservice communication with RabbitMQ"

Tetiana Chupyra
Tetiana Chupyra

Microservice applications are useful only if they work in cooperation. So an adequately chosen type of inter-service communication is golden. In this talk, I want to speak about building lightweight microservice messaging with a usage of RabbitMQ. Why it’s better than standard JSON over HTTP? When it should be used and when should not? How to integrate RabbitMQ in Ruby application? I have some thoughts and answers that I want to share with you all.
