This short talk will explain how javascript handles being both single-threaded and non-blocking. We'll demystify the "Event Loop" and how concurrency works in javascript. If a coworker ever helped you solve a bug by wrapping a function with a setTimeout(myFunc, 0) and you felt cheated, this talk is definitely for you. MP3

Popular culture and sci-fi have introduced us to some pretty cool artificially intelligent characters. But how far are they from reality? In the last years many advances have been made in the field of artificial intelligence. What has been done so far? What does the future hold? And how scared should we be of meeting a real-life Terminator on the street? I'd like to give you a glimpse at the answe...

Dealing with multiple teams in a product development organization is always a challenge. I would like to share with you a live case study about how we switched from a traditional R&D structure into a small product oriented start-up’s teams. These are some of the challenges we had to deal with: How to brake a single product development team into small pieces while keeping autonomy and productiv...

What is software design? How does it relate to writing code? many of us are using agile methodologies nowadays, but how can we reconcile these with the concept of software design as we currently know it? In this talk, I will share with the audience my personal journey with Test-Driven Development (and Design) over the last 4 years, a journey that started with me assuming that I know what TDD is an...

Committing to Continuous Delivery at EverythingMe meant that we had step our game up when it comes to version quality visibility. Our existing solution simply didn't cut it, so we created MAGNETO - "Command your Droids - an open source Android Test Automation framework focusing on speed, ease and visibility. In this talk I'll elaborate on how this awesome tool came to be, what's so special about i...

In a conversation with Chef and Puppet practitioners in the company I heard the same complaint over and over again. Configuration Management is sooo much better than manually configuring servers, but it is painful because all the configuration points that you still need to manage. Enter Service Discovery, a way to connect our different services together with no configuration. Service Discovery is...

Deployment workflow: From SCM to production in an heartbeat without loosing any heartbeats. Managing image versions: Deploying & Reverting Fast. Using Docker API How Docker can crash your production and how to avoid that. Configuration management and docker Where to use Marathon/Mesos and where not. Useful scripts for collecting metrics and view logs without accessing the containers. MP3

Forter has been using Riemann for almost a year in production to monitor our highly complex distributed system. We are using Riemann as our hub for alerts(Pager Duty), latency and exception reporting(Kibana) , continuous integration and system probes (GitHub). This presentation will cover Riemann patterns for maintenance-mode, state machine based alerts, statistical alerts, system and integration...

Developing for mobile web is nothing like developing for desktop. The browser is slower, the mouse and keyboard interface switched to touch, and the usage profile is different - launch quickly, ditch even quicker. In order to get to a native-like experience, developers need to have a deeper understanding of the browser, know the limitations, and get acquainted with new ways to do things that were...

We all love developing single page web apps, it's fast, snappy, cool, and makes us (developers) happy. Most of the logic lives in the client, and it doesn't need to refresh the page to fetch new data. That's all great but it's comes with lots of flaws like poor SEO, long first page load time and code logic duplication between client and server. What if we could just take the pros from both single...

Swift is a shiny new language for iOS development, introduced during WWDC 2014 (June). We'll try to answer the following questions about Swift: Is Swift production ready? What is the current state of Swift and its development tools? Should you learn Swift or Objective-C if you have no background in iOS development? Should you write your next iOS app in swift if you already know Objective-C? I have...

Whether you own a small GitHub project or a part of a well-known application, understanding what people REALLY think about your product is critical. "Talk with your users!” and "Track what they do!" are two of the most common pieces of advice you’ll hear. The problem is that the users you can track or talk to are far and away those that use and like the product. To get a complete view of your prod...

Having a public API is a common approach when companies want to make the shift from being a solution and become a platform. In the last year, while developing Outbrain's Amplify public API, we had dilemmas, we faced challenges and learned valuable lessons. In this session I will share what we have learned in term of development, execution and management of a public API, and will talk about things...

After many years of Java development on various projects as a developer or architect and leading other Java developers, I felt that we can do better; we, Java developers, can be more productive. We can achieve more with less ceremonies. We can get things done with less code. And then I met Groovy. It was not a love at first sight: "Hey, no type declarations? No return statement? No.... ". But then...

A talk presenting how we modeled and designed our services in AppsFlyer: How Micorservices work for us, how we deal with deployment, service discovery, SOC, storage etc. How the data that is sent to AppsFlyer is modeled as a stream of events which is delivered over Kafka and how using Kafka allows us to easily deploy new services, keeps us resilient and even helps us test our code. How using Cloju...

A cool story about the evolution of our monitoring infrastructure. From the naive approach to a super resilient system. How do we manage to handle 4M metrics / minute, and over 1K concurrent connections? What strategies did we try to apply and where did it fail? What are the techniques and technologies we use in order to achieve this? How do we handle errors, and failures at this scale? What can w...

In 6 years, Wix grew from a small startup with traditional system architecture (based on a monolithic server running on Tomcat, Hibernate, and MySQL) to a company that serves 60 million users. To keep up with this tremendous growth, Wix’s architecture had to evolve from a monolithic system to microservices, using some interesting patterns like CQRS to achieve our goal of building a blazing fast hi...

Storm is an obvious choice for high-throughput processing but it's a little out of its territory when you also need to maintain low latency. It doesn't have to be that way, though. We at Forter devised a few components and practices to help us build scalable high-throughput and low-latency storm topologies for our real-time fraud detection system. We'd like to share some of the lessons we learned...

How do you know what 60 millions users like? Wix.com is conducting hundreds of experiments per month on production to understand which features our users like and which hurt or improve our business. In this talk we’ll explain how our engineering team is supporting our product managers in making the right decisions and getting our product road map on the right path. We will also present some of the...

So you've heard of this newfangled "Scala" thing and think it might be worth checking out. Good for you! Unfortunately, it's also daunting. Your first search for Scala is likely to pitch it as a "statically-typed hybrid object-oriented and functional language", which is technically true but doesn't really help much. Instead, this talk will provide an overview of the language, focusing on five high...

There are many BI systems. What's different and challenging about dashboard in particular is the combination of simplicity and actionability which makes building and optimization of an interactive dashboard a damn hard problem. Come and learn more about real life techniques of how to build a big data interactive dashboard.   MP3

The vast amount of code available on the web is increasing on a daily basis. Open-source hosting sites such as GitHub contain billions of lines of code. Community question-answering sites provide millions of code snippets with corresponding text and metadata. The amount of code available in executable binaries is even greater. In this talk, I will cover recent research trends on leveraging such "b...
