May 27, 2015: Kamelia Aryafar and Jerry Soung - Looking Through Camera Lenses: The Application of Computer Vision at Etsy
Looking through Camera Lenses: Computer Vision and its Applications in Etsy
Online retail is a visual experience – shoppers have particular styles that they find appealing; often images are used as first order information when making shopping decisions. There are a variety of signals extracted from the images representing those items for sale by shoppers. Amongst these, color composition, image features and various quality scores serve as important cues for visual search and image ranking. Often shoppers have a palette of favorite colors, or a mental image of what they’re looking for. Moreover, images can be used to extract meaningful information for security applications such as duplicate and tamper detection.
In this talk, we present a review of the state-of-the-art mathematical models for image processing including feature and signatures extraction, matching and classification for tag recommendation, search by color and duplicate detection among other applications. We introduce the applications of these technologies at Etsy and discuss our experience and challenges integrating these technologies with our existing models.

Building Smart & Opinionated Security Warnings
SSL is supposed to protect your e-mail, Tweets, and bank records from network
attackers. Most of the time, SSL keeps your data safe — but sometimes the SSL
connection setup fails. When this happens, your browser will warn you about the
risk and ask you what to do. These warnings are problematic because often
neither the browser nor the user knows whether the error indicates a real
attack. Chrome’s security team is tackling this problem by building smarter and
more opinionated warnings. I’ll talk about both challenges: first, how we’re
using design techniques to make our UI more convincing; and second, how we’re
combining client and crawler data to improve warning accuracy.
About Adrienne Porter Felt
Adrienne Porter Felt is a software engineer on the Chrome security team, where
she is the tech lead for Chrome usable security. In this role, she works on

Every Problem is a Scaling Problem
When I joined Twitter, it was a 50ish person company. When I left, I had 400 people reporting to me alone globally. Developing “Twitter scale” infrastructure and slaying the fail whale is usually what most people talk about — but what about the lessons learned operating a team at scale?
About Raffi Krikorian
Raffi was, until August 2014, Twitter’s VP of Engineering in charge of the Platform, the core infrastructure of Twitter. He managed 400 people who worked on, amongst other things, the business logic, the scalable services, APIs, storage, core libraries, and the internal development model of all of Twitter.
Before Twitter he used to create technologies to help people frame their personal energy consumption against global energy production (Wattzon – Business Week’s “Best Idea” 2008), fueled his television habit through writing “TiVo Hacks” (O’Reilly, August 2003), and also ran a consulting company building off-the-wall projects. At one point, he also used to teach at NYU’s ITP (created the class Every Bit You Make) and spent way too much time as a student at MIT and the MIT Media Lab (Internet 0 – Scientific American September 2004).
The Past, Present, and Future of Responsive Images
The goal of a “responsive images” solution is to deliver an image ideally suited to the end user’s ever-changing context, rather than serving the largest potentially necessary image to everyone. Unfortunately, this hasn’t proven to be quite so simple in practice as it seems to be in theory. Small screens should get smaller images, sure, and large screens should get larger ones. Naturally, only high-resolution displays should qualify for high-resolution images, but what if that user has limited bandwidth available? Would the low-resolution image be preferable—and at what point? Explore the path to a standardized solution, look at some of the proposals that will be shaping our future work; and learn techniques we can use to start saving our users’ bandwidth today.
About Mat Marquis
Mat “Wilto” Marquis works at Bocoup; formerly Filament Group. Mat is technical editor and contributor at A List Apart, Chair of the Responsive Images Community Group and an editor on the W3C HTML5.1 specification.

The role of the product organization is to consistently deliver significant new value to the business through continuous product innovation. Yet most teams don’t deliver that value. They just make minor optimizations to existing products. Or they continue to toss more features onto the pile. Further, most people that talk about innovation do so in the context of a new startup, but in existing businesses there are significant additional challenges as in order to innovate we must do our discovery work in ways that protect our brand, our revenue, our employees and our customers. In this talk I will describe the critical cultural and process changes necessary for your organization to continuously and consistently deliver the value your company and your customers need.

Open Source has radically changed the way that companies do software development. We used to live in a world where each company re-built everything from scratch, but openness has allowed us to collaborate on common components, reducing duplication and driving down costs. Can we apply these same lessons to other areas? Balanced thinks so. In this talk, Steve will talk about the “Open Company Initiative,” which applies similar kinds of openness to product development, pricing, and other business practices that are traditionally fully closed. He’ll also show an example of how this openness actually changed some of the code Balanced has written.
About Steve Klabnik
Steve is a prolific Open Source contributor, member of the Ruby on Rails team, and Balanced’s philosopher in residence. He’s the author of several books: “Designing Hypermedia APIs,” “Rails 4 in Action,” and “Rust for Rubyists.
Join us as Marcus and Laurie reprise their highly acclaimed talk first presented at Velocity Europe.
Relying on a single content delivery network for your site can impose a number of flexibility limitations. By diversifying your CDN providers you can put the power back in your hands, allowing you to get the best of both worlds in terms of performance, reliability and cost. In this talk Marcus and Laurie will present Etsy’s recent work integrating multiple CDN providers to their site delivery infrastructure.
Building web sites and applications is a pursuit where we learn a great deal and can be reasonably successful in a very short period of time. But to become true masters of our craft, we investigate subtleties and nuance in an effort to perfect our work, aiming for constant improvement. We specialize in areas of performance, scalability, maintenance and more. It is part of what we do as dedicated professionals who are committed to our craft. Accessibility is one of many areas where details matter.
In this talk, Derek will guide you through a tour of design and development decisions that we make that ultimately play a significant role on the utility of an interface – more significant than we think. You’ll see examples that will help you question standard practice and convention as you see first hand the impact our decisions make.

Oh, the elusiveness of “One Web”. And yet, increasingly users treat the web as one experience — add a product to your cart from your phone during the morning commute, and finish the transaction in the afternoon at work from your desktop computer. This discussion examines what’s required to present a consistent, delightful experience to users regardless of where the experience begins, continues, and ends. You’ll learn to avoid development mistakes committed by even the most seasoned among us, and you’ll see plenty of examples from teams big and small doing it right.

When I tell people I spent a decade studying computer science at MIT and CMU, most assume that I focused my studies in information retrieval — after all, I’ve spent most of my professional life working on search.
But that’s not how it happened. I learned about information extraction as a summer intern at IBM Research, where I worked on visual query reformulation. I learned how search engines work by building one at Endeca. It was only after I’d hacked my way through the problem for a few years that I started to catch up on the rich scholarly literature of the past few decades.
As a result, I developed a point of view about search without the benefit of academic conventional wisdom. Specifically, I came to see search not so much as a ranking problem as a communication problem.
In this talk, I’ll explain my communication-centric view of search, offering examples, general techniques, and open problems.

Watson Research Center and AT&T Bell Labs. He currently serves as an advisor for LoopIt, Maana, and Origami Logic.
Daniel pioneered the annual symposium on human-computer information retrieval and wrote the first book on faceted search. He was an undergraduate at MIT, double majoring in math and computer science. He completed a PhD at CMU, developing new algorithms for graph layout. He was born and bred in Brooklyn, and lived in New York City most of his life before moving from Brooklyn Heights to Mountain View in 2010 — where he’s still looking for a good bagels and a great karaoke joint.
We get alerts all of the time in this connected world we live in. As engineers, we build alerts to tell us when things are not going as expected. There’s a wealth of knowledge from many non-internet fields that we can learn from in this topic. I’ll talk about alert design from the perspective of Human Factors, and the cognitive costs of alerts: data overload and underload, numbness, and trust in automation. We’ll talk about a few hints on making progress on designing alerts to be useful, not a pain in the ass.
Beyond Media Queries: An Anatomy of an Adaptive Web Design
Media queries may be responsive design’s secret sauce, but we know there’s a whole lot more that goes into crafting amazing adaptive experiences. By dissecting an example of a mobile-first responsive design, we’ll uncover the principles of adaptive design and highlight some considerations for creating contextually-aware Web experiences. We’ll go over emerging mobile Web best practices and responsive patterns that can assist in our journey toward a future-friendly Web.

Trust, Security, and Society: Human society runs on trust. We all trust millions of people, organizations, and systems every day — and we do it so easily that we barely notice. But in any system of trust, there is an alternative, parasitic, strategy that involves abusing that trust. Making sure those defectors don’t destroy the cooperative systems they’re abusing is an age-old problem, one that we’ve solved through morals and ethics, laws, and all sort of security technologies. Understanding how these all work — and fail — is essential to understanding the problems we face in today’s increasingly technological and interconnected world.

Design for Continuous Experimentation
The design and product process must adapt to accommodate data. This is a tour through the joys and woes of product development when experimentation and measurement are center stage. It is a case for baking honesty and humility into our methods. This is a reprise of a talk originally given at the Warm Gun 2012 conference in San Francisco.
