Personal schedule for Shevek .

Clojure is a general-purpose language with direct support for Java, a modern Lisp dialect, and support in both the language and data structures for functional programming. Learn Clojure and you'll become a better all-around programmer. You'll also be able to write applications that have the beauty and elegance of a good scripting language and the power and reach of the JVM. Read more.

This session will introduce you to the JavaFX 2 platform from the perspective of a seasoned Java developer. The breadth of JavaFX APIs will be explained through several examples that we will build out during the course of the session. Read more.

Are you tired of null pointer exceptions, SQL injections, concurrency errors, mistaken equality tests, and other run-time errors? A compile-time tool named the Checker Framework has found hundreds of such errors in Java code. Come learn how you can use the tool to improve your own code. For those who don't use Java, we will explain the concept of pluggable type-checking that underlies the tool. Read more.

Storm is an open-source realtime computation system relied upon by Twitter for much of its analytics. Storm does for realtime computation what Hadoop did for batch computation. It has a huge range of applications and combines ease of use with a robust foundation. Since being open-sourced, Storm has been adopted by over 25 companies. Read more.

The speakers recently stumbled across a time machine containing a system built in Java 8 technology which has fallen back in time. This talk will explain some of the advanced features and future code archeology of this amazing find! Read more.

With its latest release (2.4.0), Apache httpd is ideally suited for the cloud, both in performance and capability. See what enhancements have been made so that you can also take advantage of Apache 2.4.0. Read more.

You package your assets. You use CSS sprites. You serve up everything with gzip compression. You obsess over Yslow recommendations. But you are still not SPDY. Fundamental limitations in HTTP and TCP/IP still add up to 60% overhead to your site. Find out how to reclaim that lost bandwidth and increase the robustness of your sites at the same time. Read more.

Why don't more companies practice code review? We all know how beneficial it is, and we've all seen it's successes in open source. What's so hard about bringing it over to the world of commercial software development? Nothing! This is a success story about adopting code review from the open source community and applying it to commercial development. It worked for us. It can work for you too. Read more.

Grace Murray Hopper's famous motto, "It's easier to ask forgiveness than permission", has many useful applications -- in Python, in concurrency, in networking, as well of course as in real life. However, it's not universally valid. This talk explores both useful and damaging applications of this principle. Read more.

This talk will include a review of the breadth of ZooKeeper features and use cases in low latency systems like ad platforms, high latency WAN environment and high throughput deployments. The talk will also include the future roadmap for ZooKeeper. Read more.

Compilers don't just turn C into binary, they transform data, and the optimizer is a critical decision-maker in the process. If we understand both, we can often solve tedious data transformation, scheduling or logic problems with very little effort. This presentation will teach you the magic, and convey a wealth of experience. Attendees have been known to subsequently write compilers. Read more.

The Disruptor is an open source concurrency framework developed by LMAX, a London financial exchange. While it’s fashionable to use languages to hide away multithreading, the Disruptor does the opposite - enables developers to parallelize their architecture easily. In this session, Trisha Gee will show how to use the Disruptor, proving that concurrent programming doesn't have to be complicated. Read more.

Integrating a distributed database with standard test-driven development techniques can be next to impossible, especially the breadth and complexity of failure scenarios that need to be created. This Session, led by Nate McCall of DataStax, will show attendees how to make the best of the open source utilities and projects available for integrating Apache Cassandra with your testing environment. Read more.

Metaprograming is the dirty little secret behind the success of many Java frameworks such as Spring and Struts2, and constitutes the backbone of many of the most fundamental APIs across the JEE technology stack. This session aims introduce the topic and highlight with code examples the different mechanisms and techniques to take advantage of this underused feature of the Java Programming Language. Read more.

First done at OSCON 2010, we though this session was extremely useful in helping developers work better with Googlers and Google technology and we’ll be able answer most questions that they might be baffled about. Read more.

Recent shifts in the tech world - including PaaS, cloud-services, and NoSQL - have dramatically altered the manner in which software is written, deployed, and run. This talk will discuss how PostgreSQL fits into - and can potentially take advantage of - this world. Read more.

Message Queues are a hot topic, but not all are created equal. After reviewing most of the popular choices, I will review my findings and offer suggestions for which to use when, and pros and cons of each. On the list are RabbitMQ, Kafka, Apache Qpid, Kestrel, ZeroMQ and more as time permits. Read more.

The intense commercial competition between technology companies is driving large volumes of complex and often multi-jurisdictional patent litigation. With the de facto possibility of patenting software related ideas in various countries, free and open source software developers must understand the patent risks inherent in the development and distribution of their software. Read more.

Based on our experiences with the LJC and other OSS projects we cover several tips and tricks used to build a vibrant community of thousands of passionate developers and get those communities working with each other and how to deal with conflicts and other war stories! Read more.

This session demonstrates how to troubleshoot the common problems that lead to hung and slow Java applications by going through case studies derived from actual problems we have seen on our production systems. Each case study is accompanied by a live demo of the tool best suited for troubleshooting that particular problem. Read more.

This session provides an overview of PostgreSQL 9.1 Foreign Data Wrappers, a mechanism for retrieving data from remote data sources. We will contrast the native C interface with the Python interface provided via the Multicorn project. A real-world example will retrieve business data from salesforce.com and combine it with data held in native PostgreSQL tables using a simple SQL JOIN. Read more.

While there are many ways to design compute clusters, leveraging fast message queueing for all facets of system operation may be among the most elegant. Topics will include job collection, automatic load balancing, analytics, monitoring, and scaling. Learn real-world best practices and gotchas discovered while scaling an AMQP-based document processing backend to support over 8 million users. Read more.

The JVM is capable of amazing network throughput and performance when used properly. Different languages (Java, Scala, Clojure), programming approaches (Asynchronous IO, Blocking IO) can greatly affect throughput and latency. This talk will draw on experience building networks of millions of devices to discuss best practices and contrast emerging idoms on the JVM. Read more.

The optimizer is the "brain" of the database, interpreting SQL queries and determining the fastest method of execution. This talk uses the explain command to show how the optimizer interprets queries and determines optimal execution. Read more.

This session will teach you how to pull together jQuery, LESS, Twitter Bootstrap, Java, and Play Framework to build the Client/Server web app. You will also learn how to deploy Client/Server web apps on the cloud using a Content Delivery Network (Amazon CloudFront) for the Client and a Cloud Application Provider (Heroku) for the Server. Read more.

Long before WoW and whatever else the kids are playing these days, we had telnet and multi-user dungeons with huge expansive worlds, clever writing and tons of charm. People still use IRC, why not MUDs? As a huge fan of the genre I wanted to write my own, this is my journey. Read more.
