Join us for an evening of Tech Talks: PDX Edition at Urban Airship's space in the Pearl. This evening's theme is high-performance network programming.

Scott Andreas will talk about network-level oddities that are important to think about when designing high-performance network applications. Lower-level TCP behaviors such as incast, Nagle's algorithm, and tcp_retries2 are a few examples of what we'll learn about – and how to avoid getting hit by them when you don't expect it!

Erik Onnen will speak on designing and implementing network-intensive applications on the JVM, with a focus on high-throughput and low-latency IO. He'll dig into different frameworks for languages like Java (Netty), Scala (Akka), and Clojure (Aleph), synchronous vs. async IO – and how to decide which to go with. Specific topics will be drawn from practical application building large scale, high throughput messaging systems dealing with millions of mobile devices.
