Next Thursday, September 13th we are going to have a guest from Boston, Philip Tellis, he's a co-founder and CTO of LogNormal, a company that provides Real User Monitoring as a service.
Prior to starting LogNormal, Philip worked with Yahoo!'s performance and security teams where he built the Boomerang JavaScript library (among other things).

RUM was one of the leading themes at Velocity this year and Philip was doing a great presentation there.

Here's the description of the talk from Philip:
While building boomerang, we developed many interesting methods to measure network performance characteristics using JavaScript running in the browser. While the W3C's NavigationTiming API provides access to many performance metrics, there's far more you can get at with some creative tweaking and analysis of how the browser reacts to certain requests. In this talk, I'll go into the details of how boomerang works to measure network throughput, latency, TCP connect time, DNS time and IPv6 connectivity. I'll also touch upon some of the other performance related browser APIs we use to gather useful information.

We are at Animoto offices again - with food and drinks as always!
