Although you could download Dojo from its official Web presence and set up a local installation, the easiest way to get started with Dojo is to use the latest version of Dojo that is hosted on AOL's Content Delivery Network (CDN). The following page skeleton demonstrates that the minimal effort required to put Dojo to work from the CDN is a SCRIPT tag that loads Dojo into the HEAD of the page; it is especially noteworthy that the SCRIPT tag incurs the cost of one request to the Web server that delivers a gzipped payload of approximately 29kB and provides the latest 1.1.x release that is available. In Dojo parlance, the good that the SCRIPT tag provides is called Base, because it provides the base for the toolkit, and because everything you'll use is contained in the base-level dojo.* namespace. Speaking of which, with the exception of the dojo identifier itself, the global page-level namespace is otherwise preserved:
To summarize, the dojo.addOnLoad block fires once the asynchronous loading of the dojo.xd.js file and any dependencies specified via dojo.require statements (more on these in a bit) have completed, and this is necessary in order to prevent any race conditions that might occur without it. Basically, the dojo.xd.js file providing Base accomplishes feats such as normalizing DOM events and provides you with a number of useful utilities for accelerating application development.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
