According to HTTPArchive.org the average web page is now larger than the original DOOM installation application. Today's obese web is leading to decreased user satisfaction, customer engagement and increased cost of ownership. Research repeatedly tells us customers want faster user experiences. Search engines reward faster sites with better rankings. Small, fast sites are cheaper to develop, maintain and operate.
- Why has the web become obese?
- What actions can developers and stakeholders do to combat their morbid obesity?
- Are these actions expensive or hard to implement?
This session reviews what customers want and how to identify your web site's love handles. More importantly you will learn simple techniques to eliminate the fat and create a healthy, maintainable, affordable web development lifestyle that produces the user experiences your customers want to engage with over and over.

Optimizing web performance (Fronteers edition)Dave Olsen
Today, a web page can be delivered to desktop computers, televisions, or handheld devices like tablets or phones. While a technique like responsive design helps ensure that our web sites look good across that spectrum of devices we may forget that we need to make sure that our web sites also perform well across that same spectrum. More and more of our users are shifting their Internet usage to these more varied platforms and connection speeds with some moving entirely to mobile Internet.
In this session we’ll look at the tools that can help you understand, measure and improve the web performance of your web sites and applications. The talk will also discuss how new server-side techniques might help us optimize our front-end performance. Finally, since the best way to test is to have devices in your hand, we’ll discuss some tips for getting your hands on them cheaply.
An overview of web development essentials that will help you as a user experience designer to not only understand how to integrate designs with development components, but also to learn some tips on interacting effectively with developers.
These are the slides from my talk "Your WebPerf Sucks" at HK CodeConf 2015 (http://hongkong.codeconf.io) at Science Park in Hong Kong, October 24th.
Web Performance is an important aspect of building for the web and this talk highlights different aspects of what is important and what can be done to improve web performance and build faster sites. While mentioning different aspects of possible improvements, the main focus lies on optimising the critical rendering path to get pages on the screen faster and what tools can help to do so.
Raiders of the Fast Start: Frontend Performance Archaeology - Performance.now...Katie Sylor-Miller
Raiders of the Fast Start: Frontend Performance Archeology
There are a lot of books, articles, and online tutorials out there with fantastic advice on how to make your websites performant. It all seems easy in theory, but applying best practices to real-world code is anything but straightforward. Diagnosing and fixing frontend performance issues on a large legacy codebase is like being an archaeologist excavating the remains of a lost civilization. You don’t know what you will find until you start digging!
Pick up your trowels and come along with Etsy’s Frontend Systems team as we become archaeologists digging into frontend performance on our large, legacy mobile codebase. I’ll share real-life lessons you can use to guide your own excavations into legacy code:
What tools and metrics we used to diagnose issues and track progress.
How we went beyond server-driven best practices to focus on the client.
Which fixes successfully increased conversion, and which didn’t.
Our work, like all good archaeology, went beyond artifacts and unearthed new insights into our culture. We at Etsy pride ourselves on our culture of performance, but, like all cultures, it needs to adapt and reinvent itself to account for changes to the landscape. Based on what we’ve learned, we are making the case for a new, organization-wide, frontend-focused performance culture that will solve the problems we face today.
Responsive Web Design for Universal Access 2016Kate Walser
You can improve how well your website works and looks across different devices using responsive web design techniques. But did you know you can also improve access for all users, including those with disabilities, by applying responsive techniques? Learn how.
In the beginning, progressive enhancement was simple: HTML layered with CSS layered with JavaScript. That worked fine when there were two browsers, but in today's world of multiple devices and multiple browsers, it's time for a progressive enhancement reboot. At the core is the understanding that the web is not print - the same rules don't apply. As developers and consumers we've been fooled into thinking about print paradigms for too long. In this talk, you'll learn just how different the web is and how the evolution of progressive enhancement can lead to better user experiences as well as happier developers and users.
This deck is a conference-agnostic one, suitable to be shown anywhere without site-specific jokes!
Web Developers are excited to use HTML 5 features but sometimes they need to explain to their non-technical boss what it is and how it can benefit the company. This presentation provides just enough information to share the capabilities of this new technologies without overwhelming the audience with the technical details.
"What is HTML5?" covers things you might have seen on other websites and wanted to add on your own website but you didn't know it was a feature of HTML 5. After viewing this slideshow you will probably give your web developer the "go ahead" to upgrade your current HTML 4 website to HTML 5.
You will also understand why web developers don't like IE (Internet Explorer) and why they always want you to keep your browser updated to latest version. "I have seen the future. It's in my browser" is the slogan used by many who have joined the HTML 5 revolution.
Building performance into the new yahoo homepage presentationmasudakram
Nicholas Zakas presented on optimizing the performance of the Yahoo homepage redesign from 2010. The new design added significant functionality but also increased page size and complexity, threatening performance. Areas of focus included reducing time to interactivity, improving Ajax responsiveness, and managing perceived performance. Through techniques like progressive rendering, non-blocking JavaScript loading, and indicating loading states, performance was improved and maintained users' perception of speed. The redesign achieved onload times of ~2.5 seconds, down from ~5 previously, while perceived performance matched the previous version.
The document discusses improving mobile web performance. It notes that mobile is different than desktop due to limitations in power, memory, battery and connections on mobile devices. Sites are growing larger in size which slows performance, and users strongly prefer faster loading sites. A variety of tools can measure performance, and waterfalls charts show where time is spent loading pages between the server and client. Optimizations discussed include enabling caching, compression, image resizing, lazy loading images, inlining images and scripts where possible, minifying assets, and delivering scripts and styles in a single HTTP request through techniques like application caching.

Accidentally Manager – A Survival Guide for First-Time Engineering ManagersTheo Jungeblut
This session is about your career perspective as an engineer, especially when the path may take an “unexpected” turn from technical lead to first-time engineering manager.
We will explore the differences between managing and leading, review different management styles, and discuss their impact on both the manager and the team member. Finally, we will find out why you do not want to treat everyone equally. I will share my personal experiences going from being one of the team to actually managing it: the pitfalls of suddenly being responsible for the team, typical problems surfacing, and how to avoid common mistakes. As part of the session,
I would also like to share thoughts and considerations about which career path could be the right one for whom, and what the advantages and disadvantages are going one way or the other.
This is not a “You get it all from the expert”- session, but a session to share experiences and discuss how this fits to your career path.
Note: Moving forwards this presentation will be updated with the latest version of the slides for the last event I did the presentation instead of creating new separate slide decks here on SlideShare.

All 3 Clean Code presentations provide great value by themselves, but taken together are designed to offer a holistic approach to successful software creation. This first session creates the foundation for the 2nd and 3rd Clean Code presentation on Dependency Injection, as it explains expected base knowledge. Why writing Clean Code makes us more efficient Over the lifetime of a product, maintaining the product is actually one - if not the most - expensive area(s) of the overall product costs.
We will dive into the basics of Inversion of Control (IOC) and Dependency Injection (DI) to review different ways of achieving decoupling, using and exploring both: Best Practices, Design and Anti Patterns. This presentation requires knowledge and understanding of basics like DRY, SoC, SRP, SOLID etc. which are building the base for decoupled architecture. However, we will start at the basics of DI and will work towards intermediate and advanced scenarios depending on the participating group.
This presentation is based on C# and Visual Studio 2013. However, the demonstrated patterns and practice can be applied to every other programming language too.
Note: Moving forwards this presentation will be updated with the latest version of the slides for the last event I did the presentation instead of creating new separate slide decks here on SlideShare.

Optimization 2020 | Using Edge SEO For Technical Issues ft. Dan TaylorDan Taylor
This document discusses using edge computing technologies like content delivery networks (CDNs) to overcome technical barriers to SEO implementation and perform edge SEO. CDNs allow SEO implementations to be done serverlessly at the edge without touching origin source code. Examples of edge SEO include dynamically generating meta titles and tags, redirecting, AB testing, collecting pseudo server logs, and dynamically rendering JavaScript to resolve issues. Edge SEO provides benefits like speed, security, and enables implementations that may otherwise be restricted by platforms. Potential issues include impacting all requests and introducing latency, but recent developments have reduced these concerns.

Introduction to Progressive Web ApplicationsChris Love
Progressive Web Apps (PWAs) are websites that utilize modern web capabilities to deliver native app-like experiences to users. PWAs are built using common web technologies including HTTPS, service workers, and web app manifests. Service workers allow PWAs to work offline by caching app assets and responding to fetch events. When installed on a user's homescreen, PWAs can load quickly and feel like native applications while retaining the benefits of the web such as being discoverable, installable, and updatable.
Introduction to Progressive Web ApplicationsChris Love
Progressive Web Apps (PWAs) are websites that utilize modern web features to deliver native app-like experiences to users. The minimum requirements for a PWA are that it is served over HTTPS, includes a web app manifest, and registers a service worker. Service workers allow PWAs to work offline by handling fetch events and caching assets. While adding a PWA to a user's home screen can improve engagement, the true battleground is changing user perception of the capabilities of web apps versus native apps.
Progressive Web Applications are a new way to think about using the web to provide great user experiences using the best web platform features.
The education market has many opportunities to benefit their communities using PWAs to deliver information and application experiences across all devices and platforms.

Real World Lessons in Progressive Web Application & Service Worker CachingChris Love
Over the past year we have seen a lot of excitement around Progressive Web Applications. Browser evangelist are selling developers and business owners on their advantages and promising future. But what is the real story? What are the details to proper execution? What do engineers need to know to make their web sites into Progressive Web Applications that not only meet the minimum criteria, but meet the sales hype?
Searching the Pokedex offline is fun, what is the real experience like caching a business application? Caching application assets and data can be complex, especially for larger applications. What to cache, how long to cache and how to cache are all valid questions. Often, in an effort to just ship something, we cache nothing. When we don't cache, we disappoint the customer and miss a key promise of progressive web applications.

71. CSS Selector Specificity
• Complex Specificity
• .main-content > article #myArticleId p
• Leads to large CSS files
• Makes Code Unmanageable
• Lower the Score the Better
• Browsers Parse Selectors Right to Left
• * Avoid Universal Selector
72. Right-Left Rule
• .main-content > article #myArticleId p
• Translates to:
• #myArticleId p
• Think More Like the Browser When Defining Selectors
73. Calculate CSS Specificity
• Count the Inline Style
• count the number of ID selectors in the selector (= a)
• count the number of class selectors, attributes selectors, and
pseudo-classes in the selector (= b)
• count the number of type selectors and pseudo-elements in the
selector (= c)
• ignore the universal selector
