WebSocket is a protocol that provides bidirectional communication over a single TCP connection. It uses an HTTP handshake to establish a connection and then transmits messages as frames that can contain text or binary data. The frames include a header with metadata like opcode and payload length. WebSocket aims to provide a standard for browser-based applications that require real-time data updates from a server.

Things to be aware of when you are measuring the performance of your web sites (both synthetic testing and Real User Monitoring).

The document discusses various techniques for improving front-end website performance, including reducing the number of HTTP requests, using content delivery networks and caching, gzip compression, optimizing CSS and JavaScript loading, image optimization, and lazy loading of content not visible initially. Specific techniques mentioned include combining files, setting long cache expiration headers, minifying files, parallelizing downloads, and deferring non-critical JavaScript initialization. The goal is to render an initial version as fast as possible through optimizations that reduce page load time.

80% of the time it takes for a web page to load is on the client side. Using all the tips in this presentation should cut 25% to 50% off the load time of optimized page requests. Drupal (6 or 7) can be used to, fairly easily, implement a whole bunch of these “front-end performance” upgrades, and knock a ton of errors off of the Yahoo! and Google speed-checker tools validation checklists.Get firebug first.

Sascha Corti With Internet Explorer 9, Microsoft has entered the league of HTML 5 browsers and with its active participation in the W3C working groups, the company proves its engagements towards the new and emerging standards. Developers however are often left wondering where the boundaries are drawn between HTML5 web site, plug-in based rich internet application and smart client or “app”. This session intends to answer this question and uses many examples to show you some of the most important enhancements introduced by HTML5, CSS3, SVG, DOM, WOFF and ECMA script. You will learn now the standards are still evolving and how Microsoft is contributing. http://soft-shake.ch/2011/conference/sessions/microsoft/2011/09/06/introduction-to-html5.html

This talk will explore new territory and showcase tools that help you debug complex and difficult issues in your WordPress site.

John Resig has been researching the mobile space and wants to ensure jQuery works well across popular mobile platforms and browsers. He discusses the challenges of defining the relevant platforms and browser versions due to a lack of public statistics. His testing strategy involves drawing a line to determine what to support, buying devices, downloading simulators, and using TestSwarm for automated testing. He recommends simulators and devices for different levels of support.

Khan Academy provides a computer science education platform where students can learn programming through hands-on experimentation and by viewing other students' code. The site allows code to be "forked" from other students and versioned. Code is executed in real-time using Processing.js for graphics and by dynamically injecting code into the runtime to handle changes rather than simply re-evaluating it. Errors are handled through JSHint validation and additional "BabyHint" error handling.

This document discusses how computer vision techniques can be applied to art history. It provides an overview of different computer vision approaches such as optical character recognition (OCR), face recognition, and image similarity/categorization. Unsupervised techniques like OCR and image similarity require little labeling of data but may not provide as interesting results. Supervised techniques can more precisely locate parts of images or categorize images but require large labeled datasets. The document recommends several free and open-source computer vision libraries and tools that can be used to explore applying these techniques to art history, along with some caveats about training data requirements.

- JavaScript is a dynamic and loosely typed language that is often used without formal training. It can be used to manipulate the DOM and features functions, numbers, booleans, strings, objects, arrays and more. - While JavaScript borrows aspects of object-oriented programming, it is not strictly object-oriented. Simple design principles like passing tests, removing duplication, increasing clarity and keeping code small are more important. - Writing tests is key to developing simple and maintainable code. Tests help ensure code quality, allow refactoring, and serve as documentation. Functions should be small, isolate DOM elements, avoid closures, and prevent duplicated views.
