One of the more intriguing features of Metro-X is multi-screen support. If you use Metro-X MGA video cards, four monitors can be operated simultaneously (see Figure 2). Applications can be loaded into their own screens and controlled by a single mouse and keyboard. A GUI based utility is provided to handle the physical screen layout and mouse movement (see Figure 3). I would love to play around with this configuration, but my wallet won't cooperate.
As with most modern X servers, multiple screens and virtual resolution are supported. I cringe whenever I have to work on a system that doesn't allow these features. I normally work in several applications at once, and trying to cram multiple windows into a single screen is a nightmare.
There is also the fail-safe escape method. If the X server freezes or your mouse becomes disabled, Metro-X can be brought down by pressing the ctrl, alt and backspace keys simultaneously. This is a lot quicker than pressing ctrl-alt-f1 to get a virtual console, then killing the X Server process.
If you're into video capture, MPEG playback or video conferencing, Metro Link sells a video suite called Metro-Media. The application runs on Metro-X with Motif and can be used by developers and end users.
For developers and end users who use Motif-based applications, Metro Link also supplies Motif 2.0 at $199US.
I immediately noticed a performance increase when Metro-X was installed on my system. It seems to be a very stable environment. Several programs that misbehaved under XFree ran great with Metro-X. Before Metro-X, Netscape was continually giving me trouble—now, it runs like champ.
Support options are dependent on where you purchased the package. If you received it from Red Hat, Red Hat provides the support. Red Hat offers on-line support at http://www.redhat.com/ and phone support at 1-800-546-7274.
If the purchase was made directly from Metro Link, they provide support through e-mail at email@example.com and phone support at 1-954-938-0283.
I have yet to encounter a problem that required a tech request, so I can't speak to the quality of support.
With the ease of configuration, stability, available options and enhancements, I think Metro-X is a real bargain. I recommend it highly to anyone who wants to spend his time producing instead of configuring.
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
