Programming KDE 2.0: Creating Linux Desktop Applications
It's a wonderful thing when a book about software includes the software to which it refers. The author has tried to do this and with some forethought as to the various distributions on which KDE 2.0 might be loaded. Having run previous versions of KDE, I wasn't squeamish about testing it. This was, after all, a newer release that is better, from some reports, than previous versions. (Some outfits insist that “eats more RAM” is synonymous with “better”.)
Suffice it to say that a certain libmng was missing from the Debian binaries, resulting in a grumpy reviewer, an unhappy 64MB of RAM (which was slowed down to the point of unusability) and a crashing bore of a hard drive. Looking for the missing library entailed a wild goose chase of several hours and bore no fruit. libmng requires zlib. Requires it but can't see copies of it.
If you have a lot of RAM, like C++ and like creating desktop applications, Programming KDE 2.0 is quite an acceptable guide. If you're running Debian, don't use the CD that comes with the book; go to the KDE site (http://www.kde.org/) and download it. The book will come in handy as a reference. And if you don't like KDE, the title alone should put a stop to any impulse buying.
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
