Accelerated-X v. 2.1 & Metro-X 3.1.2
Before we get to The Chart, I did notice one interesting thing while I was playing around with the two servers. If /usr/X11R6/bin/X is a soft link to an XFree86 server, such as XF86_SVGA, AccelX will move the XFree86 server to X.LINUX. If, however, /usr/X11R6/bin/X is linked to, oh, say, Xmetro (the Metro-X server), then AccelX will turn Xmetro into a link to Xaccel, destroying the Xmetro server. Hmmmm.

I am currently running Metro-X. I have two friends who swear by X Inside. Which server is better sort of depends on your needs. Metro-X has more support for commercial applications, including multi-head display and touch-screen capabilities. Accelerated X supports more graphics cards, making it more likely to suit your hardware.
Bottom line? Check your hardware against both lists, and if both servers will meet your needs, flip a coin—they're both cheaper than a day spent calculating modelines.
The mouse trouble noted in our review of Accelerated X—the mouse flinging applications off the desktop and causing a disruptions to the server connection—have been resolved.
Linux kernel version 2.0.0 introduced a problem with the Async mouse feature of Accelerated X. (This feature allows the mouse to move around the screen even when the X server is busy doing something else—a usability trick Microsoft has been using for a while on their Windows product.) X Inside notified the Linux kernel team and worked with them to correct the problem. With release 2.0.26 of the kernel, the error was resolved.

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
