10 Web Performance Lessons For the 21st Century

Slides from my May 23 webinar for the ADA Great Lakes Center. Overview of the state of things for WordPress and accessibility and the principles of web accessibility.

The document discusses the challenges facing the progressive web and introduces progressive web apps (PWAs) as a solution. PWAs are built using modern web standards to provide native app-like experiences through features like push notifications, offline support, and app installation. They address issues with native apps like high installation friction, lack of control for publishers, and app store policies. PWAs are gaining adoption from companies like Alibaba and Housing.com who saw increases in user engagement metrics after implementing PWAs. The document outlines the core components of PWAs and provides an overview of browser and platform support.

This document summarizes a presentation about improving efficiency and performance on the web. It discusses Moore's Law, which states that computers get faster every two years, and May's Law, which says software efficiency halves every 18 months to compensate. However, web development has focused too much on innovation and new technologies rather than optimization. As a result, median page load times are over 5 seconds. The document calls for developers to focus on fixing existing issues, improving efficiency, and testing new standards like ES6 before adopting them widely. It argues for less hype and more focus on users, technical limitations, and fixing broken aspects of the current web.

This document discusses responsive web design. It begins by outlining the failures of separate mobile websites and native apps. Responsive design is identified as the key approach because it allows for one website with a layout that adapts to any screen size. The document then covers various aspects of responsive design such as thinking mobile first, information architecture considerations, designing in the browser versus Photoshop, using a fluid or fixed grid, and making design decisions beyond just visual design.

This document discusses the importance of web page speed and provides tips to optimize performance. It emphasizes that speed is important for user experience and engagement. Slow pages can lead to high bounce rates and negatively impact SEO. It then provides the "golden rules" of optimization, which include reducing HTTP requests, minimizing file sizes, caching assets, and using techniques like lazy loading. Specific tools are recommended for measuring performance, including PageSpeed, Speed Tracer, and Dynatrace Ajax. Browser limitations and upcoming technologies that may improve speed are also briefly covered. The goal is to make the web faster by optimizing code, images, assets and more.

Progressive Enhancement is one of the most important and useful software engineering tools in our web development toolbox, but in practice it's largely ignored. We'll dive into the basics of PE, the common pitfalls (think <noscript> and the newer class="no-js"), how to support Blackberry 4.x and IE6 without a ton of extra work, tools to avoid that violate PE best practices, and how to apply PE pragmatically.

Chris Heilmann gave a talk celebrating beautiful web sites but noted that many sites could be more optimized. He highlighted that the average site is over 2 MB in size, with images making up over 1 MB of that. Many sites use unnecessary libraries, send high resolution images to all devices, and include autoplay videos without checking connection speed. However, newer browser capabilities like Flexbox, Service Workers, and camera/microphone access provide opportunities. Sites should cut unnecessary code, optimize images, and leverage new technologies to create accessible experiences for all types of users on today's capable browsers.

The document provides an overview of responsive web design. It discusses techniques like using media queries and mobile-first approaches to adapt styles based on screen size and other factors. It covers best practices like letting content determine breakpoints, treating layout as an enhancement, and accounting for different user contexts. It also highlights common mistakes to avoid and emphasizes the importance of testing designs on actual devices.

The document discusses the evolution of the web from progressive web apps to native mobile apps and back again to progressive web apps. It notes that early mobile web faced issues like small screens, poor connectivity and unreliable browsers, leading to the rise of native apps. However, app distribution issues like slow updates and the "walled garden" approach of app stores have led to a renewed interest in progressive web apps that work offline but do not require app stores, allowing for more open distribution like the original web.

Dev Ops is hard and can seem like another language. This talk given at WordCamp Belfast hopes to help new developers, project managers and agency owners a chance to improve the WordPress Dev Ops Workflow

This document discusses finding a balance between automated and manual accessibility testing. It notes that automated testing is not a substitute for manual testing but should be part of an accessibility program. Both automated and manual testing have advantages and disadvantages. The document emphasizes that bringing together automated testing, manual testing, and an engaged team with the right skills and responsibilities is key to a successful accessibility strategy. It provides tips on how to divide responsibilities and set up a testing and training program to balance automated and manual approaches.

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.

Responsive web design has hit the scene like a bomb, and now designers everywhere are showing off to their bosses and peers by resizing their browser windows. "Look! The site is squishy!" While creating flexible layouts is important, there's a whole lot more that goes into truly exceptional adaptive web experiences. This session will introduce the Principles of Adaptive Design: ubiquity, flexibility, performance, enhancement and future-friendliness. We need go beyond media queries in order to preserve the web's ubiquity and move it in a future-friendly direction.

This document discusses the history and challenges of responsive web design. It notes that the way people access the internet has changed significantly since 2009, with many more people now using mobile phones to access the web. Traditional web design approaches no longer work as well. The document discusses new design methods for responsive web design, such as style tiles, element collages, and style prototypes that allow designing directly in the browser rather than with static Photoshop comps. It emphasizes the need to have real conversations with clients about the design process rather than presentations.

This document discusses WordPress theme performance. It provides data from testing over 3,800 themes on metrics like speed score, number of resources, file sizes, and response bytes. The median theme in 2016 had a mobile speed score of 53, 432KB in total assets, and response bytes of 125KB for HTML, 101KB for CSS, and 155KB for JavaScript. Recommendations include optimizing assets by consolidating and minifying files, deferring non-essential scripts, and conditionally loading resources. The document emphasizes including performance in designs from the start and selecting themes that meet defined performance budgets.

This document outlines an agenda for a web performance training course. It introduces key concepts like why performance matters, how to define and measure performance metrics, and how to identify and address performance problems. It provides numerous links to tools and resources for auditing site performance, establishing performance budgets, monitoring performance over time, and optimizing code and assets to improve loading speed. The goal is to help attendees learn how to evaluate the performance of their sites and make them faster.

As a Tester you need to level up. You can do more than functional verification or reporting Response Time In my Performance Clinic Workshops I show you real life exampls on why Applications fail and what you can do to find these problems when you are testing these applications. I am using Free Tools for all of these excercises - especially Dynatrace which gives full End-to-End Visibility (Browser to Database). You can test and download Dynatrace for Free @ http://bit.ly/atd2014challenge

This document discusses techniques for improving web performance. It begins with research on how caching and cookies impact performance. It then outlines 14 rules for optimizing performance, such as making fewer HTTP requests, using content delivery networks, gzipping components, placing scripts at the bottom of pages, and avoiding redirects. Case studies demonstrate how following these rules can significantly improve page load times. The document emphasizes starting performance improvements by focusing on front-end optimizations and advocates evangelizing best practices.

Today, a web page can be delivered to a desktop computer, a television, or a handheld device like a tablet or a phone. While a technique like responsive design helps ensure that our web sites look good across that spectrum of screen sizes we may forget our web sites should also be able to perform equally well across that same spectrum. While more and more of our users are shifting their Internet usage to these more varied platforms and connection speeds our development practices might not be keeping up.In this session we’ll review why optimizing web performance should be an important step in the development of responsive websites. We’ll look at the tools that can help you understand and measure the performance of those sites as well as discuss front-end and server-side techniques that can be used to help you improve their performance. Finally, since the best way to test your site is to have real devices in hand, we’ll share “lessons learned” so you can set-up your own device lab similar to what we have at West Virginia University.This presentation builds upon Dave’s “Optimization for Mobile” chapter in Smashing Magazine’s “The Mobile Book.”

It provides examples of responsive sites and recommendations for implementing responsive design best practices for a variety of technical and content-related challenges in ecommerce. The presentation emphasizes the importance of planning content strategies that work across devices before implementing design and technology solutions.

1) Rachel Andrew discusses considerations when choosing tools and frameworks for front-end development projects, emphasizing progressive enhancement and ensuring the core experience works for all. 2) She argues against over-reliance on frameworks, which can mask issues and prevent learning core skills. Frameworks should be used lightly and evaluated on a case-by-case basis. 3) Andrew talks about the importance of standards-based development and contributing to emerging specifications like CSS Grid Layout, rather than depending entirely on pre-processors. Her goal is to encourage continued progress of the open web.

The goal of Serverless is to focus on writing the code that delivers business value and offload everything else to your trusted partners (like Cloud providers or SaaS vendors). You want to iterate quickly and today’s code quickly becomes tomorrow’s technical debt. In this talk we will show why Serverless adoption increases the developer productivity and how to measure it. We will also go through AWS Serverless architectures where you only glue together different Serverless managed services relying solely on configuration, minimizing the amount of the code written.

Web tech­nologies are evolving at such a frenetic pace that it becomes almost mandatory to learn on your own. A lot of us still depend on other people to do this learning for us, and we tend to use their answers to solve our everyday problems. Inconsistent imple­men­ta­tions, rapidly evolving specs, ques­tionable perfor­mance impacts and main­te­nance impli­ca­tions mean we cannot always depend on others for answers but must involve ourselves actively in the process of devel­oping spec­i­fi­ca­tions for new Web tech­nologies. But how do we go about it? There are some simple rituals we can all do, which can have us be better-​​informed and also better inform the people and groups who are most directly involved in the devel­opment of new Web tech­nologies.

A brief introduction to responsive web design presented to Biomedical Communications (MScBMC) students on March 15, 2013.

Let’s see how web components can help us to build accessible, test covered and consistent implementation of our design system that will play well with any technology.

While the principles of responsive web design can make sites look better on mobile devices, they don’t necessarily load faster than a site designed for desktops. And as more and more sophisticated WordPress themes emerge, with their multiple options and fancy sliders, websites just keep getting more and more bloated. This presentation will help cut out the junk that’s larding up your sites so you can better meet the demand of users wanting fast-loading user experiences–no matter the device or connection. Presented at WordCamp Salt Lake City 2013 (http://2013.slc.wordcamp.org/)

This document discusses web components and package managers. It provides an overview of popular front-end frameworks and libraries from the past like React, Angular, and VueJS. It explains that web components will replace other forms of web development by providing a standard way for code to be reusable while maintaining compatibility. Package managers like NPM are important tools that developers widely use to manage dependencies. The document advocates that web components create a foundation for significant leaps in development capabilities by solving problems around design systems, templates, and libraries.

This document provides an agenda for an immersive workshop on styling and catching up.

Stream processing is a crucial component of modern data infrastructure, but constructing an efficient and scalable stream processing system can be challenging. Decoupling compute and storage architecture has emerged as an effective solution to these challenges, but it can introduce high latency issues, especially when dealing with complex continuous queries that necessitate managing extra-large internal states. In this talk, we focus on addressing the high latency issues associated with S3 storage in stream processing systems that employ a decoupled compute and storage architecture. We delve into the root causes of latency in this context and explore various techniques to minimize the impact of S3 latency on stream processing performance. Our proposed approach is to implement a tiered storage mechanism that leverages a blend of high-performance and low-cost storage tiers to reduce data movement between the compute and storage layers while maintaining efficient processing. Throughout the talk, we will present experimental results that demonstrate the effectiveness of our approach in mitigating the impact of S3 latency on stream processing. By the end of the talk, attendees will have gained insights into how to optimize their stream processing systems for reduced latency and improved cost-efficiency.

Are you interested in dipping your toes in the cloud native observability waters, but as an engineer you are not sure where to get started with tracing problems through your microservices and application landscapes on Kubernetes? Then this is the session for you, where we take you on your first steps in an active open-source project that offers a buffet of languages, challenges, and opportunities for getting started with telemetry data. The project is called openTelemetry, but before diving into the specifics, we’ll start with de-mystifying key concepts and terms such as observability, telemetry, instrumentation, cardinality, percentile to lay a foundation. After understanding the nuts and bolts of observability and distributed traces, we’ll explore the openTelemetry community; its Special Interest Groups (SIGs), repositories, and how to become not only an end-user, but possibly a contributor.We will wrap up with an overview of the components in this project, such as the Collector, the OpenTelemetry protocol (OTLP), its APIs, and its SDKs. Attendees will leave with an understanding of key observability concepts, become grounded in distributed tracing terminology, be aware of the components of openTelemetry, and know how to take their first steps to an open-source contribution! Key Takeaways: Open source, vendor neutral instrumentation is an exciting new reality as the industry standardizes on openTelemetry for observability. OpenTelemetry is on a mission to enable effective observability by making high-quality, portable telemetry ubiquitous. The world of observability and monitoring today has a steep learning curve and in order to achieve ubiquity, the project would benefit from growing our contributor community.
