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 traditionally coded in a much more tolerant environment. Animations, caching, forms, data, design, scrolling, event handling, etc. - all these have to be treated differently. I will share my findings from several years exploration of trying to get to that native-like promised land on the small form factor. The presentation will encompass several HTML5 and CSS3 features overview, live HTML examples of animation profiling, and a bit of tooling tips.

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 page app and a traditional server web app and build a true solution for web apps? Isomorphic javascript is the answer!

Imagine you can share your view logic between client and server, they both will be able handle routing and rendering pages. This is now possible using Node.js platform.

In this talk we'll explore the new world of isomorphic javascript, what does it mean and how you can jump on the bandwagon.

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 product, you need to be able to answer questions like: Why did users leave your product? What do users miss? And how can you bring users back? In this talk, we'll be discussing the following topics:

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 like:

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 I realized: Under the hood, it is still the same old JVM, the syntax is just different. I can progress at my own pace: Java code is already Groovy code, I can learn feature by feature and then use it at my convenience.

That is what I did. For the first few months my Groovy code was almost a Java code, but as I conquered another feature and another feature I got it: Groovy is not only improved Java, there are many new concepts that I was not aware of them before: dynamic language, closures , functional programming, meta programming and much more.

Thanks to Groovy I became a better developer. Thanks to Groovy I learnt new concepts and now I am not afraid of any new programming language (I already did my first steps with Scala).

Come and hear my ode to Groovy.

In this talk I will share my view on why every Java developer must know Groovy. Groovy may not replace Java in your organization, but it will definitely enrich your professional capabilities and make you a better and more productive developer.

And yes, I will talk about recent 'Groovy/Grails funding announcement' that created a lot of buzz recently, you definitely want to hear what I have to say about it!

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 Clojure changed how we reason about code and data and actually changed the way we develop and deploy services

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 we still improve?

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 highly scalable and highly available system.
