A Simple JavasScript Preloader
A JavaScript Preloader for HTML5 Apps PxLoader is a Javascript library that helps you download images, sound files or anything else you need before you take a specific action on your site (like showing a user interface or starting a game). You can use it to create a preloader for HTML5 games and websites. It let's you monitor download status by providing progress and completed events and it lets you prioritize the order in which items are downloaded. We created PxLoader for the HTML5 version of Cut the Rope and out of the box works great with images and sound files (the types of resources we needed for the game), but it's designed to be extensible and work with any file type or other network action. Step by Step Instructions 1. *The sound file downloader works with SoundManager 2 and allows it do the heavy lifting of the actual download. 2. 3. Download Images Before Drawing to a Canvas Images must be fully loaded before they can be drawn on an HTML5 canvas. Report Progress While Images Load Related:  JavaScript libsrobinkhatri

GoJS GoJS is the only diagram library for HTML5 Canvas that supports data binding and templates. GoJS integrates these concepts cleanly and coherently into a powerful diagramming extension to the HTML5 JavaScript environment. Diagram Models and Data Binding One of the principal features of the Model-View-ViewModel design pattern is the use of data binding. There are at least two kinds of relationships that a diagram can support between data items: Relationships forming a graph of nodes and links (or in similar terminology: nodes and arcs, or entities and relationships, or vertices and edges) Grouping relationships, where a group contains members; perhaps for part/sub-part containment, or for the nesting of subgraphs GoJS makes use of a model to discover, maintain, navigate, and modify these relationships based on the data to which the diagram is bound. If you look at our online demos, you will see how little code you need to visualize and update your data. Will result in this diagram:

jQuery SVG SVG (Scalable Vector Graphics) is a modularized language for describing two-dimensional vector and mixed vector/raster graphics in XML. It is a W3C Recommendation currently at version 1.1. SVG is a language for describing two-dimensional graphics in XML. SVG is implemented natively in Firefox from version 1.5, Opera from version 8.5, Safari from version 3.0, and in IE from version 9.0. This plugin allows you to manipulate the SVG from JavaScript. Download and include the jQuery SVG CSS and JavaScript in the head section of your page. Alternatively, you can use the minified version of the code: jquery.svg.min.js (18.7K vs 56.6K, 5.7K when zipped). Attach an SVG canvas to a <div>. Then respond to the load completion and start working with it. You can remove the SVG functionality if you no longer need it. For IE prior to version 9, you need one of the SVG browser plugins to render the documents (such as the Adobe SVG viewer or the Renesis Player). $.svg.addExtension('graph', SVGGraph); Animate

Sass vs. LESS "Which CSS preprocessor language should I choose?" is a hot topic lately. I've been asked in person several times and an online debate has been popping up every few days it seems. Really short answer: Sass Slightly longer answer: Sass is better on a whole bunch of different fronts, but if you are already happy in LESS, that's cool, at least you are doing yourself a favor by preprocessing. Much longer answer: Read on. The Much Longer Answer The Learning Curve with Ruby and Command Line and Whatever The only learning curve is the syntax. Winner: Nobody Helping with CSS3 With either language, you can write your own mixins to help with vendor prefixes. In Sass, you can use Compass, and Compass will keep itself updated, and thus the prefix situation is handled for you. In LESS, there are also some mixin libraries battling to be the best. In both cases, the onus is on you to keep the preprocessor software itself up to date as well as these libraries. Winner: Narrowly Sass Winner: Sass Winner: LESS
