Special LJC Event Held at QCon 2012

With great help from the organisers of QCon (http://qconlondon.com/) we have been able to secure three speakers that are rarely available in London for a special LJC event held at QCon.

We are lucky to have with us: Gil Tene of Azul systems, Adrian Cockroft of Netflix and the creator of Clojure, Rich Hickey.

The event will be held at The Queen Elizabeth II Conference Centre from 18.30 to 20.30 on Thursday 8th March.

Gil Tene (Azul systems) will present "The Application Memory Wall (and thoughts on the state if the art in garbage collection)"

The original "memory wall" first predicted in the mid 1990's was supposed to have been hit by now, with applications stretching server capabilities to their limits. However, today's typical application instance only utilizes 5-10% of a modern server's capacity, and the percentage is dropping.

In this session, Gil will discusses the "Application Memory Wall" and and the likely causes of an observed decade-long stagnation in application instance memory growth and consumption. Gil will analyze the key technical challenges that have led to the emergence of the Application Memory Wall, reviewing the relevant state of the art in garbage collection within managed runtimes in general, and in commercial Java Virtual Machines in particular.

Gil will outline the main technical problem areas that need industry and academic attention and focus. Gil will then dive into the details of an actual collector (Azul's C4 garbage collector, http://dl.acm.org/citation.cfm?id=1993491 ) that addresses the identified set of problems, and show how such solutions can lead to a post-Wall era - an era in which applications will once again be free to productively and naturally consume the abundant compute resources available in modern servers.

Adrian Cockroft (Cloud Architect for Netflix Inc.) will present "Netflix' Open Source Scalable Java PaaS"

Netflix has used Java for many years, as we moved to run our streaming services out of the cloud, we wrote a highly automated scalable global platform in Java, which we are now open-sourcing, git by git. This talk summarizes the basic features of Astyanax, Priam, Servo, Curator etc., which are available at github.com/Netflix and are described at techblog.netflix.com. Adrian will also describe some interesting Java "faceted type" constructs that provide a kind of multiple-inheritance for business level objects.

Who should attend: Developers and architects concerned with building large scale systems in Java.

Rich Hickey (Creator of Clojure) will present "Modeling Process".

Time, perception, values, identity, visibility, state, persistence, memory, transience, process, place, change, communication. We use these terms everyday. Yet, despite its real-world modeling flavor, OO has little to say about them. What do these terms mean, and why do they matter to our programs?


18:00: Doors Open
18:30: A series of lightning talks from members of the London Java Community
19:00: Main presentations - Gil Tene will present "The Application Memory Wall (and thoughts on the state if the art in garbage collection)", Adrian Cockroft will present "Netflix' Open Source Scalable Java PaaS" and Rich Hickey will present "Modeling Process".
20:30: Networking


Gil Tene is CTO and co-founder of Azul Systems. He has been involved with virtual machine technologies for the past 22 years and has been building Java technology-based products since 1995. Gil pioneered Azul's Continuously Concurrent Compacting Collector (C4), Java Virtualization, Elastic Memory, and various managed runtime and systems stack technologies that combine to deliver the industry's most scalable and robust Java platforms.

In 2006 he was named one of the Top 50 Agenda Setters in the technology industry by Silicon.com. Prior to co-founding Azul, Gil held key technology positions at Nortel Networks, Shasta Networks and at Check Point Software Technologies, where he delivered several industry-leading traffic management solutions including the industry's first Firewall-1 based security appliance. He architected operating systems for Stratus Computer, clustering solutions at Qualix/Legato, and served as an officer in the Israeli Navy Computer R and D unit. Gil holds a BSEE from The Technion Israel Institute of Technology, and has been awarded 28 patents in computer-related technologies.

Adrian Cockcroft is the director of architecture for the Cloud Systems team at Netflix. He is focused on availability, resilience, performance, and measurement of the Netflix cloud platform, and has presented at many conferences, including QCon San Francisco, Beijing and Tokyo. Adrian is also well known as the author of several books while a Distinguished Engineer at Sun Microsystems: Sun Performance and Tuning; Resource Management; and Capacity Planning for Web Services.

From[masked] he was a founding member of eBay Research Labs. He graduated with a BSc in Applied Physics from The City University, London.
