What is there to say about databases? They are one of the most important tools in enterprise, and yet at first glance they seem boring. However, authors and users both love them, as can plainly be seen by the number of articles (ten) that were submitted for this issue. We present five here, three in Strictly On-line and put off two for next month. We'll look at MySQL, NoSQL, PostgreSQL, Progress (next month), Oracle and the ODBC (open database connectivity) project, as well as using Java and the Web with databases. There are also reviews of DB2 and a book on mSQL and MySQL. If you don't learn something about databases this month, you must be an expert on them already.
Last month, we printed an article, “Multilink PPP: One Big Virtual WAN Pipe” purportedly by Paul Ammann. We have since learned the article was actually written by George E. Conant, formerly of Xyplex, and can be found on the Web at www.data.com/tutorials/multilink_ppp.html. We have not been able to reach Mr. Conant to offer our apologies personally, but do so here in this forum. We put a large amount of trust in the authors with whom we contract; Mr. Ammann has betrayed this trust both to us and to our readers. When I asked him about it by e-mail, he sent this reply:
From: firstname.lastname@example.org (Paul Amman) Subject: RE: [email@example.com: Boo! Hiss! (fwd)] Date: Tue, 31 Aug 1999 20:49:05 -0400 Well... to be honest, yes, I did copy the article. I guess there's no hiding it and it's time to own up to it now. There is no good explanation that would be acceptable for my behavior. Please advise me on what retribution I must make. I will accept full responsibility for my actions. Paul
We are extremely distressed that this happened—the only time in over five years of publishing.
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
