Learning to Use X11
There aren't many resources available for X11 programming, in particular not for beginners. Some useful ones are:
Christophe Tronche' X11 Pages: Includes a short tutorial covering essentially the same material that has been covered here. This site is interesting because the entire Xlib reference is available. I strongly recommend browsing it.
Brian Hammond's X11 Pages: Another personal X11 page with a tutorial, containing a little bit more information than Tronche's tutorial but less organized.
XFree86 Version 4.1.0: The official page for the current release of the open-source version of the X Window System. At the bottom of the page one finds the complete set of man pages.
Xlib Programming Manual by Adrian Nye. Volume 1 of the X Window System Series at O'Reilly. The book is wordy (it needs three chapters and almost 80 pages to cover not much more material than the present article), and the presentation is not always noted for its clarity. Nevertheless, it is probably still the standard introduction to X11 programming.
X Window Applications Programming by Eric F. Johnson and Kevin Reichard. One of the few truly introductory books on X11 programming but unfortunately out of print.
Philipp K. Janert has been programming for 15 years, both inside and outside of academia. He prefers C/C++ and UNIX but tries not to be religious about it. He holds a PhD in Theoretical Physics from the University of Washington, Seattle.
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
