Cassandra has always been a highly performant distributed database, but not always simple to use though. Apache Cassandra 1.2 finalizes CQL3, a query language which provides a new interface to communicate with Cassandra that dramatically shrink its learnin...

Vert.x is the new polyglot asynchronous application framework for the JVM from VMware that enables you to write effortlessly scalable asynchronous, web-enabled applications in JavaScript, Java, Ruby or Groovy. In this talk Tim will be explaining why the g...

The ability to chat with your fellows is an important feature of games and social applications. In the talk I discuss chat features of mobile and web applications. I start by describing messaging protocols and focus on XMPP. Then I present techniques of co...

Riak is one of the new breed of no-SQL database management systems, which has begun to replace relational databases for some applications. Riak is a distributed key-value store, inspired by Amazon’s Dynamo, designed for applications where scalability, low ...

The world of data speaks a different language than the world of programming languages. It uses REST, SQL database schema, XML, JSON while programming languages only understand types and classes. This causes big confusion when we try to access data from pro...

A brief journey through the scaling that we had to deal with at Zeebox, and how running on the JVM allowed us to bring some very effective and mature tools to bear on profiling & load-testing tools to bear, how we primarily use Akka as an asynchronous/even...

At Wooga we are creating the next generation of social games. To be truly social, a game needs to offer real interaction between players in different forms. Taking one of our upcoming games as an example we will present the state synchronization used in ...

We believe that one should never have to choose between productivity and scalability, which has been the case with the traditional approaches to concurrency and distribution. The cause of that has been the wrong tools and the wrong layer of abstraction and...

In this talk we'll explore some of the innate properties of (social) graphs from fields like anthropology and sociology. By understanding the forces and tensions within the graph structure, we'll be able to predict how the graph will evolve over time. In...

Designing systems in Java is very different from designing systems in Erlang. In this talk, I'll report on my journey from being an expert Java developer into the land of Erlang concurrency and systems design. As always when you travel to foreign places, y...

This talk will start with a little bit of the history and motivations behind building the Disruptor and some of it's current problems. Then by doing a whistle-stop tour through non-blocking concurrency in Java it cover the changes coming into version 3.0 ...

Social Architecture by analogy with conventional architecture, is the process and the product of planning, designing and growing an on-line community. Social architectures, in the form of on-line communities, are the cultural and political symbols and work...

Riak is a scalable, reliable, open source distributed database modeled after Amazon Dynamo, and it also supplies additional features such as secondary indexes and full text search. Riak is accessible via a wide variety of programming languages but is imple...

It is no longer possible to ignore the reach of JavaScript. Thanks to the web, JavaScript is one of the most widely distributed programming languages. Thanks to intense coporate competition between Google, Apple, and Mozilla, JavaScript engines are some of...

The Actor Model has interesting properties that could be used for dealing with complexities posed by modern embedded systems. Using actors as compositional units to describe these systems is a new proposal which stands out and challenges conventional appro...

Software engineering can be considered a process: developing a system from its current state to its ideal state. For many problems in large-scale web environments, Go is an excellent tool to facilitate that process. A very brief introduction to the languag...

Proponents of functional programming tout its many benefits, most of which are available only within a particular process, or afforded by a particular programming language feature. Anything outside of that is considered I/O, dangerous and difficult to reas...

This talk will examine the promise, potential and pitfalls of functional programming (FP) - both as a potential alternative to and extension of more widely-used programming paradigms. Drawing on real-world industrial experience of the exclusive use of pure...

Data modeling is hard, especially in the world of distributed NoSQL stores. With relational databases, developers have tended to store normalized data and shape their query model around that structure. This can come back to bite you when it comes time to s...

How our view of networking must evolve to address the multi-core crisis! I'll be describing LINC: an Open Source OpenFlow switching platform developed in Erlang, intended for use with the OTP. I will also introduce OpenFlow, the Open Network Foundation, a...

In the talk I start by describing how Spil Games built a successful online gaming platform and what technical & organization challenges we encountered along the way. Then I will focus on architectural solution that we settled on and how this will resolve s...

The three of us (Joe, Robert and Mike) have more than years combined experience of programming. We have noticed the vast majority of software development projects use programming languages based on concepts which were developed close on a half a century ag...

Over the course of 4 years as a startup in the configuration management space, Opscode has seen a lot of code come and go. We've just completed a full rewrite of the server side API from Ruby in Unicorn to Erlang in Webmachine, with amazing improvements i...

In this talk, I will present some of the work we are doing at IntelliFactory to enable creating mobile and web applications with F# that can interface with social networks such as Facebook. I will demonstrate how using various functional programming techni...

Faith and evolution provide complementary--and sometimes conflicting--models of the world, and they also can model the adoption of programming languages. Adherents of competing paradigms, such as functional and object-oriented programming, often appear mot...

You’ve probably heard about Haskell by now, but life is short, so why should you bother about yet another programming language? In this talk we’ll focus on three distinctive aspects of Haskell that you might make it worth the bother. First, purity: uncontr...
