The application source code and images are available from O'Reilly's web site as one big Zip file. The book does contain the source code listings, but since some of them contain over 400 lines, I suggest downloading the file instead of trying to type the code from the book. While the code is not heavily commented, Mr. Bradenbaugh thoroughly explains it in the body of the book.
I downloaded the source code and ran all of the applications first on my home computer and then over the Web from my home page. All the applications run quickly within a browser and most of them load fairly quickly, even over a dial-up connection.
Each chapter ends with a section called Potential Extensions. These sections provide thoughts on how the reader can extend and modify the application that was just presented. While some code snippets are provided, the majority of the work is left to the reader to accomplish.
Mr. Bradenbaugh provides quite a bit of explanation and code showing how to have your code determine if it is running on a Netscape or a Microsoft browser, then run correctly when doing such things as DHTML. I tried running some of the applications on both Netscape and Microsoft browsers, and they worked correctly each time.
The book's applications demonstrate good attention to detail. Such things as positioning buttons correctly when creating a page, positioning new browser windows so that they don't completely cover existing windows, and putting search results in alphabetical order are hallmarks of polished applications.
I did not find any errors in the book, and there were no errata on O'Reilly's web site when I looked. The only thing that was not correct as stated in the book are the web addresses for Internet Explorer information. These pages were moved by Microsoft when they redesigned their site.
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
