March 9th — Web Sockets and Garbage Collection Please note, we’ve lost our room at the Auraria Campus, and we are moving to a room at Lowry. Here’s our location: Building 758 Rm. 138-140 1059 Alton Way Denver, CO 80230 Here are links to the map and driving directions: http://www.cccs.edu/Docs/About/LowryDirectory.pdf http://www.cccs.edu/Docs/About/DrivingDirectionsToLowry.pdf Come learn how to use WebSockets to enable bi-directional communication between a server and a browser. This will be followed by a discussion on the internals of Azul’s JVM.
Location: Building 758 Rm. 138-140 1059 Alton Way Denver, CO 80230 5:30-6:00: Food, Soda and Networking We are grateful to Tek-Systems for their continued sponsorship of the Food and Soda! *** BASIC CONCEPTS *** 6:00-7:00: Introduction to WebSockets: All the Bi-Directional Duplexing You Can Handle! One of the most exciting new additions to the suite of technology collectively known as “HTML 5″ is an official WebSocket standard. This finally allows full duplex bi-directional communication between a client and server over HTTP.
However, the technology is still new and rapidly changing. In this talk, Johnny will explain what a WebSocket is, how it works, how to implement it on browsers that don’t natively support it, and how it relates to other technologies and platforms such as HTTP long polling, Comet, Flash Sockets, mobile, and JSONP. He’ll also discuss the different types of server implementations, scaling strategies, and how a it can be integrated into an existing application.

You want your low-latency cake and have high throughput too? For years Java engineers have debated strategies to improve Java runtimes, but conventional JVM approaches have always placed low-latency and high-throughput as mutually exclusive design elements.
Add on the desire for large heaps and you’re pushing engineering pipe dream. But it’s not heresy, just innovation and hard work, that we can now deliver a JVM that does it all for commodity servers. In this session we’ll bust the myth that JVM performance is limited by either low-latency or high-throughput design tradeoffs and demonstrate consistent, low-latency response times with high, sustained allocation rates using 10s of x86 cores and 100s of GBs of memory About Mark D.
