The Yahoo Query Language is an expressive SQL-like language that lets you query, filter, and join data across Web services. With YQL, apps run faster with fewer lines of code and a smaller network footprint. Yahoo and other websites across the Internet make much of their structured data available to developers, primarily through Web services. To access and query these services, developers traditionally endure the pain of locating the right URLs and documentation to access and query each Web service. With YQL, developers can access and shape data across the Internet through one simple language, eliminating the need to learn how to call different APIs. How Do I Get Started? Check out the YQL Console.

Rending your XML as HTML with XSLT in Rails. I had a need to convert XML services that my rails app was providing into customizable html widgets tht could then be in-jested by some sort of server side includes(like NGINX's SSI).
So I needed to use XSLT. When the W3C wrote the XML specification they also developed the Extensible Stylesheet Language for Transformations. Rails on XML, Part 1: Background. [Part of the Rails on XML series.]
I'm sure the first question in many readers' minds is "Why bother? ". The intersection between the XML community and the Ruby community is very small. A rubyist might use XML to implement a RESTful web service, but that's going far enough, thank you very much.

You are here: Home Dive Into HTML5 Diving In HTML 5 defines the <canvas> element as “a resolution-dependent bitmap canvas which can be used for rendering graphs, game graphics, or other visual images on the fly.”

Basic animation steps These are the steps you need to take to draw a frame: Clear the canvas Unless the shapes you'll be drawing fill the complete canvas (for instance a backdrop image), you need to clear any shapes that have been drawn previously. Controlling an animation Shapes are drawn to the canvas by using the canvas methods directly or by calling custom functions. HTML5 Canvas Cheat Sheet.

The information is pretty much just a copy of what is found in the WHATWG specs, just condensed and hopefully a bit easier to read. There are virtually no explanations, however, and no examples other than some graphics for compositing values and a few other things (the appearance of which is very much inspired by those found in Mozilla's examples). So, it's basically just a listing of the attributes and methods of the canvas element and the 2d drawing context.
The aim of this article is to explore the process of creating a simple app along the way learn: How to draw dynamically on HTML5 canvas The future possiblities of HTML5 canvas The current browser compatibility of HTML5 canvas.
