Learn how easy it is to learn and use Elixir and Cowboy (A concurrent and fault-tolerant HTTP server) in a short time - from figuring out how to build a distributed In-App messaging system, to deployment and production. You'll also hear about why Erlang/Elixir are perfect for realtime messaging. MP3

The full story behind a highly successful immune system we implemented for the "New Google Sites". We will discuss key decisions and present the design of the system that we built, touching a wide range of devops topics: Production tests Webdriver vs. RPC probers What environments we have and how are they pushed (CI/CD, etc.) Capacity testing, load testing, Canarying What worked, what went wrong, and what were the surprising wins Blackbox vs. whitebox alerting Capacity planning and request costs What the oncaller dashboard looks like Postmortem culture MP3

At Ravello Systems we were relying heavily on CI/CD since the very early days. During the first 4 years of the company, our CI/CD framework changed and evolved to the point it went out of control and we decided to take all the experience from these years into a new and improved CI/CD. This session will share the lessons that we learned when we used multiple different tools as part of our DevOps work and why we choose to move to Ansible for provision environment on demand, setup vm, deploy code and orchestration of our tests flows. We would discuss the process of re-doing the CI/CD from the beginning in small steps over more than a year while a large always developing group continue to push changes to production on daily basis. To support the move we added new Ansible provisioning module that create environments in Ravello and new inventory for those environments. Since our backend is deployed in AWS directly and our tests runs on top of Ravello we added abstraction layer that allow us to write roles and playbooks that works on both environments without change. We will describe the technical aspects of this move including Jenkins integration, deployment module we developed and how we build and install client product we develop on multiple OSs. MP3

Considering “Conway's Law” as an axiom, I aim to consider several aspects of how the organizational communication structure effects software design. Rapid changes within cross-timezones organizations influence software architecture processes. What can engineers or architects do to guarantee a productive and quality assuring design and implementation process, that foresees ongoing organizational changes. Organizational changes are another requirement of the design and implementations of software system.

We are all constantly told that having a healthy work-life balance is critical, but what does it really mean? Can we really separate life and work? Forget everything you ever heard about work life balance, and find out what you can do instead.

How many times do we ask ourselves this question? what is good enough? others might call it - what is the MVP? In the session, I will cover some key questions and guidelines on how to decide what is MVP, including examples - all in 5 minutes!

microRNAs are bio-markers, which may indicate cancer and other diseases even at early stages. We partnered with a startup to develop a pipeline and NLP classifiers to analyze medical research documents to find relations between genes and microRNAs, and diseases. The generalized code and leanings are open sourced.

Let's discuss some "provocative" ideas in Software Development, that beyond being provocative - make some sense:
Inheritance is a bold violation of OOP Principles.
Duplicate code when you are not sure about the abstraction.
Copy-paste as a legit method of code reuse.
Git is not so good for you.
You spend too much on Unit Tests.
Reduce testing, and replace it with better production monitoring.
