From the Editor - Web Technologies for Business Apps
No matter how long it took, the “real” version on a proprietary platform somehow never seemed to have the stability, performance or maintainability of the version you put together with Perl, Python or PHP. The good news is that now, even for the most conservative employers or clients, you no longer have to redo your Linux projects on an approved platform.
The tools you have been using to build Web sites that aren't business-critical now are seeing action in core business apps at more and more companies.
There's always someone who says that you can't possibly develop business apps on that—it doesn't have feature X. Soon, though, someone does write feature X for the new platform, or it turns out that you don't need feature X to do business apps anyway. Then new projects that could have gone with the legacy platform start going to the new one.
That's what's happening right now with the all-free, all-open source LAMP platform, consisting of Linux, Apache, MySQL and the “P” languages—Perl, Python and PHP.
Giovanni Organtini and Luciano M. Barone cover one large success story on page 36. Their LAMP-based work-flow management system, used in assembling a particle physics instrument with 500,000 parts, has replaced a proprietary system. The new system cuts CPU and memory loads, improves performance and, most important, slashes the amount of time that operators spend interacting with the system, giving them more time to work on the product.
On page 50, Tom Adelstein has some encouraging news: the LAMP platform also is the basis of US government IT projects at the Navy, the Department of Labor and other agencies. He reports that state and local governments are succeeding with Linux too. Selling to the government is hard, but the consulting firm gOSapps LLC has done more than 500 apps for 400 government bodies. Fewer of your tax dollars are being wasted on lock-in, but there's still work to be done.
Doc Searls has been following IT's biggest behind-the-scenes story for a year now. Customers are using the power of Linux and other open-source software to take control of their own technology decisions. Acronym alphabet soup and projected releases in 2005 or 2006 might make for entertaining reading, but when you've got a project to do, it's time to break out the tools that give you freedom. Doc reports on Linux successes at Morgan Stanley, Ticketmaster and Ernie Ball, on page 48.
Customer-facing Web sites have long taken advantage of Linux's performance, flexibility and low total cost of ownership. The record industry, however, hasn't been on the best of terms with the Web. Time to start over. On page 42, John Buckman explains how he is running a record company that treats both the audience and the artists with respect, not with Digital Rights Management or other such indignities. I'm listening to an album I bought from the site right now.
Whatever your business or your pleasure, there's something for you in this issue. It's not all about the Web, either. With the article by Brett Schwarz on page 72, you can build a custom phone system that saves money, integrates voice over IP and even gives you a pop-up warning of special callers. Have a productive and successful month, and see you next time.

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
