He then spent a few years in Yahoo building products and explaining and training people including Yahoo Answers, Search, Local and Maps. He then worked at Mozilla moving HTML5 support forward and advocating Firefox OS as an open alternative to closed mobile systems. Chris wrote two and contributed to eight books on web development and wrote many articles and hundreds of blog posts for Ajaxian, Smashing Magazine, Yahoo, Mozilla, ScriptJunkie and many more. He also wrote the Developer Evangelism Handbook in use in many companies to coach evangelists. He is currently working with the Microsoft Edge team as a Program Manager for Developer Outreach
You can expect to learn hidden DevTools secrets but also how to adopt a modern development and debugging workflow.

Patrick will go over the current state-of the art in understanding and investigating the performance of your website including a deep dive into some of the new interactive and rendering metrics coming to the web platform and how to get the most out of WebPageTest.
Web fonts are difficult to get right. An often overlooked and disruptive piece of web performance, web fonts can slow down your site and leave your visitors confused and agitated. No one wants agitated visitors. In this talk we’ll discuss useful methods to render web fonts quickly and without disruption so that visitors can do what should be a simple task—read the text. After all, web fonts are not rocket science.
Increasingly we rely on third-party scripts to deliver business-critical features of our sites – analytics, adverts, multi-variant testing, comments, recommendations, retargeting, social sharing etc.
In this talk Andy will explore how some popular types of 3rd parties affect performance, strategies for managing them and examples from sites that have tamed them.
You’ll come away with a better understanding of third-party performance, and pointers on how to reduce their impact on your visitors’ experience.
Images are by far the greatest bottleneck to performance on the web, and with the average web page size now about 2.5MB large—images taking up 65% of that—we need to tame the beast. Running images through a compression program like ImageOptim is a good first step, but what else can we do? In this engaging talk, Una will survey new image formats and dive deep into image rendering and performance optimization techniques, demonstrating practical approaches to making your web projects noticeably faster.
There are lots of reasons to get excited about new layout methods in CSS, but what impact does moving to Flexbox and Grid have on performance? And once you have decided to adopt new layout methods, are some techniques more performant than others?
In this talk we’ll take a serious look at the algorithms your browser is using in order to lay things out using Flexbox and Grid. By understanding how these algorithms work, you’ll be in a better position to make good decisions around layout, and fully take advantage of the possible performance gains of new CSS layout.
MAKING PLATFORMS AND PROCESSES PROMOTE PERFORMANCE
No matter how good you are at crafting the most ingenious, high-performance code, you need to deliver it to your users reliably. You probably also need to evolve it over time. To test it. To get it signed off. It can be painful. But it needn’t be.
This talk will look at ways to design a developer experience which then enables a good user experience.
We’ll talk about the benefits in keeping your stack simple, in using the expertise of others, and we’ll examine some performance and security benefits of the JAMstack and microservices.
