PrairieDevCon 2014 - Web Doesn't Mean Slow

This document discusses improving website performance. It outlines three pillars of performance: visibility, interactivity, and responsiveness. For each pillar, it recommends books and techniques. Tips include using tools like Firebug and YSlow, delaying initialization, throttling and debouncing events, and profiling code. While optimizations can improve performance, they also increase costs. The document emphasizes establishing a baseline and focusing first on low-hanging fruit before more complex optimizations. It concludes by thanking the sponsors and providing contact information.

As browsers explode with new capabilities and migrate onto devices users can be left wondering, “what’s taking so long?” Learn how HTML, CSS, JavaScript, and the web itself conspire against a fast-running application and simple tips to create a snappy interface that delight users instead of frustrating them.

This document discusses strategies for adding features to jQuery plugins without causing bloat. It suggests using metaplugins that handle cross-browser compatibility issues and provide core functionality. Wrapper plugins are also proposed to extend existing plugins through extension points like callbacks. The document uses the Treeview plugin as an example, explaining how an AsyncTreeview wrapper plugin was created to add Ajax support by wrapping the Treeview plugin instead of modifying it directly. This allows features to be added modularly without changing the original plugins.

jQuery is an open source JavaScript library that simplifies HTML and JavaScript interaction. It uses CSS to layer functionality and has a quick, terse syntax. jQuery selects elements and allows something to be done with them, like adding a class. It has a large plugin ecosystem managed through a plugin tracker. jQuery UI provides cross-browser user interface components. The library is fully documented, has a great community, many plugins, and small size. It works in all major browsers and is used by many large companies and projects.

This document summarizes the history and evolution of web browsers and internet technologies from the early 1990s to the late 1990s. It traces the development of key browsers like Netscape Navigator and Internet Explorer. It also outlines the introduction of important web standards like HTML, CSS, JavaScript and XML. Major events included the commercialization of the web in the mid-1990s, the browser wars between Netscape and Microsoft in the late 90s, and the consolidation of online services providers toward the end of the decade.

This document discusses using jQuery Templates and Data Link to build dynamic data-driven browser applications. It describes how jQuery Templates can be used to render templates from data but offers limited interactivity. jQuery Data Link allows binding data to HTML but has no templating. The presentation previews a new approach called JsViews that integrates Templates and Data Link to provide both fast rendering of templates to static HTML strings as well as fully interactive and responsive views through two-way data binding between templates and JavaScript data objects.

The document summarizes information about the jQuery Foundation. It discusses that the Foundation coordinates work on the jQuery code, documentation, infrastructure and events. It is a non-profit organization funded through conferences, donations and memberships. The Foundation supports jQuery projects and web developers, and participates in standards processes. Upcoming releases of jQuery will be published on Bower and npm for dependency management, use AMD internally, defer feature detects, and aim to reduce forced layouts to improve performance. Developers are encouraged to understand how browsers work and avoid patterns that can cause layout thrashing.

The document summarizes techniques for improving JavaScript performance in web applications. It discusses how JavaScript execution blocks the browser UI thread, leading to unresponsive user experiences if scripts run for too long. It then provides recommendations to limit JavaScript execution times to under 50ms and describes load time techniques like placing scripts at the bottom of the page, combining files, and loading scripts dynamically or deferring their execution to improve page load performance.

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.

Key points include: 1) Creating a shared CSS framework and responsive widgets for layouts and user interfaces. 2) Developing techniques like SVG icons with PNG fallbacks to optimize performance across different platforms and devices. 3) Building a common widget factory and APIs to create reusable and customizable interface elements that work with or without JavaScript. 4) Continuing to improve form controls and other widgets to provide consistent styling and interactions across all form factors.

The document provides instructions for creating a Christmas tree using HTML, CSS, and JavaScript. It discusses using HTML and CSS to build the basic tree structure and appearance. It then explains how to add JavaScript functionality to draw the tree on a canvas element, including drawing the triangle base and adding circular decorations. Steps are provided for setting up the file directories and boilerplate code needed to build the tree with each technology.

Zoe Mickley Gillenwater gave a talk at Generate Conference in London where she shared several mistakes she made while learning CSS flexbox and other techniques. These included misunderstanding how flex-basis works, incorrectly using CSS transforms like rotateX, and making assumptions about screen reader support that caused accessibility issues. She emphasized that vulnerability and sharing mistakes openly can help both oneself and others learn. Making mistakes is a natural part of the learning process, and perfection should not be expected or feared.

The document also covers DOM scripting techniques, tools for profiling and analyzing performance, and how the performance monitoring service Gomez can be extended to better measure client-side metrics.

Deep dive into session isolation and why search engines render pages in isolated rendering sessions to avoid having the rendering of one web page affect the functionality or the content of another. Web crawling tools aim to replicate search engines' crawling and rendering behaviours by implementing and using web rendering systems. This offers insights into what search engines might see when they are crawling and rendering web pages. While there is no defined standard for an automated rendering process, search engines (e.g. Google, Bing, Yandex) render pages in isolated rendering sessions. This way, they avoid having the rendering of one web page affect the functionality or the content of another. Isolated rendering sessions should have isolated storage and avoid cross-tab talking.

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.

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.

Discover the rich history of US Independence Day 2024, tracing its origins and evolution as a national holiday, and its significance today.

Our world runs on software. It governs all major aspects of our life. It is an enabler for research and innovation, and is critical for business competitivity. Traditional software engineering techniques have achieved high effectiveness, but still may fall short on delivering software at the accelerated pace and with the increasing quality that future scenarios will require. To attack this issue, some software paradigms raise the automation of software development via higher levels of abstraction through domain-specific languages (e.g., in model-driven engineering) and empowering non-professional developers with the possibility to build their own software (e.g., in low-code development approaches). In a software-demanding world, this is an attractive possibility, and perhaps -- paraphrasing Andy Warhol -- "in the future, everyone will be a developer for 15 minutes". However, to make this possible, methods are required to tweak languages to their context of use (crucial given the diversity of backgrounds and purposes), and the assistance to developers throughout the development process (especially critical for non-professionals). In this keynote talk at ICSOFT'2024 I presented enabling techniques for this vision, supporting the creation of families of domain-specific languages, their adaptation to the usage context; and the augmentation of low-code environments with assistants and recommender systems to guide developers (professional or not) in the development process.
