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.
Practical Task Scheduling Deployment
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

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
