Below is the preliminary list of all confirmed sessions for Velocity 2013. We are in the process of adding more content to the program, and will release the day-by-day schedule in the coming weeks.


Mobile Performance

Guy Podjarny (Snyk)
Images matter A LOT for web performance, and the variety of formats, quality levels and screen sizes complicate optimization. Retina displays, RWD and stubborn designers further fuel this fire. In this tutorial we’ll review tools and techniques that can help keep images from slowing down your page, share data about the results you can expect, and discuss what’s next for image optimization.
Jordan Williams (
Come find out (and see demos) of how to bridge the interaction performance gaps that often exist between native and web apps and create mobile web experiences that delight your users without resorting to heavy weight mobile frameworks.
Andrew Betts (Fastly)
The Financial Times web app was one of the first, and is still one of the best, examples of how HTML5 can genuinely rival native technologies in performance and user experience. But combining multi-platform interoperability with a responsive user experience remains tough. This talk will cover many of the techniques developed at the FT to meet that challenge and nurture the web platform.
Guilin Chen (Facebook)
We all know mobile performance is important. But how does it affect user engagement? We conducted a set of experiments with the Facebook app (both Android and iOS) and the Facebook mobile site to see how users would react to changes in page load time, scroll delay, or reliability.
Ilya Grigorik (Google)
Mobile networks are slow, unreliable, and have high variability both in latency and bandwidth - a nightmare to optimize for! Right? Well, almost. It’s not nearly as bad as it seems once you understand the limitations of the device and the radio network. We're going to build a 4G network, from the ground up, piece by piece, and talk about the performance implications of each and every component.
Stephen Woods (Yahoo!)
The mobile web is filled with sites that just feel slow. This talk will help make sure your site isn’t one of them. This talk will cover how to diagnose and solve runtime performance problems on mobile, covering both focusing on optimizing for interaction and data transfer.
Maximiliano Firtman (ITMaster Professional Training)
Presentation: external link
Mobile add new challenges for web performance optimization. The biggest problem is usually underestimating mobile platforms and the Facebook HTML5 app gave us some learnings. In this tutorial we will cover the mobile ecosystem for HTML5 websites and apps, how to measure performance on these platforms and how Responsive Web Design may help or harm performance, including live optimization examples.
Barbara Bermes (OANDA), Blake Crosby (Fastly)
Presentation: external link
The CBC serves optimized content to millions of Canadians. We'll share our experience and knowledge of optimizing content delivery for a high-scale and unpredictable audience.

Common patterns, production examples and operational learnings from how Netflix incorporates fault and latency tolerance into its distributed systems using circuit breakers, bulkheads and other patterns embodied in the opensource Hystrix library ( and operates them using realtime metrics and data visualization tools.
Colin Charles (Percona)
In the third edition (2012) of High Performance MySQL, MHA usage is described as: "anyone other than Yoshinori who is using it in production, and we haven't used it ourselves." Little known to the authors, we've spent quite a lot of time working on MHA and figuring out its kinks. Today MHA is in use in places like DeNA, Facebook, SK Telecom, and DAPA.
Abe Stanway (Etsy), Jon Cowie (Chef)
An introduction to Etsy's real time anomaly detection and metrics correlation systems - the newest front-line Ops tools from the team that brought you StatsD.
Adam Lazur (Facebook)
Want to learn how facebook scales their load balancing infrastructure to support more than a billion users? We will be revealing the technologies and methods we use to route and balance Facebook's traffic. This talk will focus on Facebook's DNS load balancer and software load balancer, and how we use these systems to improve user performance, manage capacity, and increase reliability.
Sam Kottler (GitHub)
This talk will cover a number of different anti-patterns, from small issues to architectural decisions that will help configuration management users of all levels build more sound configuration management scripts.
Sascha Bates (Chef)
You're on board with the awesome. You know you're going to do configuration management and automate All the Things. You might even have picked a tool. Except, now what? Where do you start? The whole world is available to automate and now it all seems kind of complicated.
Jay Edwards (Meangrape, Inc.)
In this presentation, we will show you how quickly Ansible can be used to set up a PostgreSQL deployment in EC2 using master, streaming replication, backups and monitoring agents rapidly.
Theo Schlossnagle (Circonus)
As demands for performance increase and the complexity of Internet application architectures grow, operations are abandoned in a perfect storm. The problems are ever harder to diagnose and the need to rapid remediation is more than ever. You need the right techniques and methodologies or you'll be ineffective or, worse, an obstacle. Learn them here.
Mandi Walls (Chef)
Presentation: Operations Level Up Presentation [PDF]
A walk through for improving overall operational effectiveness by building skills like statistics, software development lifecycle practices, graphing and metrics. This tutorial will focus on skill development and building better products.


Baron Schwartz (VividCortex)
One of the monitoring holy grails is knowing whether a system is behaving normally. This is usually considered a hard problem, but it can be done very cheaply at large scale. In this presentation I'll explain my definition of normality, several ways to quantify abnormality, and most importantly, what you can do with the results. There will be math, and I'll publish my slides.
Nick Berry (LinkedIn)
Presentation: external link
As LinkedIn's traffic grew, it was clear the classical approach to load balancing would not grow with us. In addition to issues with scale, we found many missing key features along the way (cookie routing, DDoS protection, etc). This talk will cover the detail of our migration, things learned along the way, plugins/patches we contributed to ATS, and how other web properties can leverage them.


Srinivas Peri (Adobe), Alex Honor (Simplify Ops), Damon Edwards (SimplifyOps, Inc.)

Velocity Culture

Gene Kim ("The Phoenix Project: A Novel About IT, DevOps, and Helping Your Business Win" ), Jez Humble (DevOps Research and Assessment LLC), James Turnbull (Empatico), John Willis (Enstratius)
We designed the 2012 DevOps Survey to learn the habits and health of the DevOps Community. We received 4,000+ responses, and the analysis yielded astonishing results. DevOps is no longer the domain of large-scale WebOps shops; it is entering mainstream. We will share DevOps practices that correlate with significantly higher business performance, as well as their demographics and psychographics.
Dylan Richard (Modest, Inc - formerly Obama for America)
How gamedays at the Obama campaign led to an uneventful Election Day.
Dan Milstein (Hut 8 Labs)
Presentation: external link
The real challenge of running an effective post-mortem is the complex, messy, all-too-human *feelings* of everyone involved. This talk gleefully tackles that challenge head on, and lays out effective techniques for helping a team to learn as much as possible after a public (and generally, pretty shameful) failure.


Adam Jacob (Chef)
Velocity is about performance and operations - and the most high performing operations organizations practice both Devops and Continuous Delivery. This talk will show you how to successfully adopt both within your organization, supported by real-world examples of victory and defeat. Revolutionary change requires revolutionary behavior - this talk tells you how to win.
Kate Matsudaira (popforms)
Being great at operations means much more than being technically competent. To be truly successful you have to understand people. Every one of your teammates and everyone one of your customers is a person. And to get what you want, you have to build trust and meaning with those people.
Jonathan Reichhold (Life On Air)
Firefighting. Not academic where you can debate for a long time. Pressure is constant. Burns many folks out but have to make local optimal decisions and keep pushing to improve.
James Turnbull (Empatico)
Operations people frequently communicate and learn through stories and mythology. We're going to examine why these stories and mythology matter, how they shape your culture and why sometimes telling these stories can give your Operation's people nightmares.
Conference talks often cover how to measure, and improve services through dashboards. This talk aims to help the audience use personal metrics gathering and visualizations to reduce interrupts, improve self assessment and manage career growth.

Web Performance

Wesley Hales (tCell), Ryan Bridges (Turner Broadcasting/CNN Digital)
PhantomJS, a headless WebKit with JavaScript API, gives us the ability to create lightweight performance measurement tools with JavaScript (and so much more). In this talk we’ll review how PhantomJS has influenced some of the web's top ranking sites and how it can be put into any automated build to produce reporting on performance.

How, a high performance web application developed by several engineers, avoids performance regression at every new release? Join us to learn more about how we make it through synthetic benchmarking and RUM.


Emily Nakashima (Honeycomb), Rachel Myers (GitHub)
As the web goes mobile, applications get asynchronous, and functionality moves to the browser, the meaning of “site performance” has moved beyond page load time. We'll talk about picking new relevant metrics, how to adapt existing monitoring tools, and how developers can tune their apps to help track what users are actually experiencing on fully asynchronous pages.
Mark Nottingham (Akamai)
HTTP guru Mark Nottingham from Akamai dives into the details of not only HTTP, but below, into TLS, TCP, IP, DNS and more, with many stops along the way to see what kinds of things can happen to your content as it gets mangled by the Internet.
Steve Heffernan (Brightcove, Video.js), David LaPalomento (Brightcove, Inc.)
Nobody likes slow video, but it doesn't have to be that way. In this session we'll explore the most performant technologies and techniques for processing video and delivering it to your viewers, including faster player loading (HTML5 + Flash), bit rate switching, peer-to-peer video, CDNs, fast and scalable transcoding, better video file compression, and accelerated file uploads.
Patrick Lightbody (New Relic), Bill Kayser (New Relic, Inc.)
When it comes to analyzing web performance data, which presentation works best? Response time plot? Median value? Standard deviation? Baseline comparison? Histogram? Apdex? With enough data you can get creative with visualizations, but which one brings the most clarity? Come look at real world performance data from many perspectives and find out which works best for your needs.
Ariya Hidayat (Shape Security)
Monitoring the performance of today's complex web applications over the coarse of the development is far from trivial. This talk discusses the emerging language tools designed for the new breed of web applications, ranging from syntax augmentation/transformation, advanced static and dynamic code analysis, as well as run-time complexity profiling.
On the web today, the most common cause of performance issues on a website is JavaScript. Some will tell you that users expect a more fluid experience now on the web and they ever have before, but does that mean you need 1MB of JavaScript? Or is there a better way?
Sergey Chernyshev (NY Web Performance Meetup), Andy Davies (NCC Group), Rick Viscomi (Google)
Join Sergey Chernyshev, Andy Davies and Rick Viscomi for a hands-on Web Performance Optimization session.

Philip Tellis (SOASTA)
Presentation: external link
While iframes have been the sandboxing method of choice by security folks, they haven't always had a good reputation for web performance. In this talk, we'll look at two techniques that use iframes to boost performance. The first is a method to load third party scripts without blocking the onload event, and the second makes updating far-future expiring content a cinch.

Colt McAnlis (Google)
Chrome implements fast, powerful webpage rendering by using the graphics hardware (GPU). But powerful GPU rendering introduces a new suite of issues that web developers need to understand. Attendees will walk away with a clear understanding of the GPU compositor in Chrome and knowledge of how their design choices will impact a page's performance on devices with GPU compositing.
Veena Basavaraj (LinkedIn)
Today at LinkedIn, javascript templates are key to building web-apps: they enable greater unification and reuse across our fragmented web-app stacks for sharing common UI code resulting in rapid iteration and innovation. The road to building this infrastructure has not been easy. In this talk we list the roadblocks, lessons learnt and our current approach for optimal web-performance.


Nicole Sullivan (Stubbornella)
CSS is a simple declarative language. Preprocessors were introduced to overcome it’s many limitations. Developers have long awaited this functionality, and the use of CSS preprocessors like SASS, Less, and Stylus has become ubiquitous on big websites. Yet CSS preprocessors often output some downright ugly code. During this talk, you will learn about preprocessor performance best practices.
Joshua Marantz (Google)
mod_pagespeed has 39 filters designed to improve web performance. Each was created because it should have positive impact on some sites. But it doesn't always work out that way. Sometimes transformations can slow sites, or interact poorly with introspective JavaScript. We'll look at some of these failures & what they can teach us about how to improve WPO technology and make better use of it.
Arvind Jain (Google)
The W3C Web Performance working group creates standards for improving web application performance including Web Timing, Page Visibility, & High Resolution Timer.

Long-time IT infrastructure investor and startup mentor Sunil Dhaliwal explains how and why software developers and IT ops professionals are the driving force behind re-imagining IT infrastructure as we know it.
Everyone who has watched a Velocity presentation knows the importance of monitoring our systems to ensure they're performing effectively. Many of the best teams go further and link their metrics to business goals to ensure the improvements they're making have a real impact on the bottom line. But despite this work the question remains: are we measuring the things that really matter?
Is it fast? Or do you just think it's fast? Does it matter?
There's a lot of talk about women in tech right now, which is a good thing. But instead of talking about what's wrong with tech, I want to talk about what's awesome about mountain biking, and how the tech community can learn from my personal experiences in that very different (yet strangely parallel) world.
We all use load balancers for various reasons – HA, Scaling, DDoS protection, Optimizations and many more. But to turn your network real estate into an Application Tap is something new and a rapidly growing trend that we will discuss in this session.
