The “X inside inside X” logo flashed on the screen then quickly went away. What happened next gave me cause for celebration. My old NEC Multisync II flashed graphics faster than ever before. My 9FX Vision 330 card was among more than 449 other video cards that AcceleratedX reportedly supports. I also found a “closer” match to my ancient monitor's specs among the 100 plus list of supported monitors and generic settings. I had more control over colors and display than ever before. While talking to pre-sales tech support, I found there are more features available that my hardware does not support. High-end equipment can support the 8/24 bit display and gamma correction features.
Before testing the new server, I loaded a copy of xbench and ran it on my stock configuration of the X312_S3 server and FVWM95-2. I used the xbench default parameters that run each test three times for ten seconds per run. I performed the same test on AcceleratedX, then compared the results. Overall process times averaged thirty percent faster with the AcceleratedX server.
Next, I loaded the AcceleratedX Common Desktop Environment. My initial euphoria faded at that point, and I began to pack up the pointy hats and party favors. The act of installing CDE had clobbered the display server installation, and there was nothing in the documentation that warned me otherwise. A quick e-mail conversation with tech support confirmed the importance of sequence and included an assurance that they would add an addendum to their release notes to warn users of this requirement. I reinstalled the display server and resumed testing.
Further investigation revealed that the X Windows configuration was also modified. The X386 directory was copied to X386.old and then re-populated per CDE specifications. Other directories like fvwm95-2 were removed from the parent directory altogether. Another annoyance came from the way CDE bypasses loading /etc/profile. None of my scripts worked. /sbin, /usr/local/bin and /usr/local/sbin were no longer in the path. After making some symbolic links to the missing directories and editing path statements, the system was back up and running, mostly as it was before. A few more words need to be added to the release notes to help customers configure their systems for test-driving CDE.
Hindsight is a great tool, if only it could be applied in reverse. I wanted to retain my configuration while testing the new software. The philosophy behind CDE does not take that scenario into account. It is fully intended to be the primary X window manager on the system, with twm as the failsafe. When the opportunity presents itself again, I will load these packages after the kernel and before adding any other applications. That way the configuration will remain consistent throughout.
The CDE's front panel is impressive at first sight. Ten frequently used programs and utilities are placed for first priority use. Other, less-used programs are embedded within pop-up menus. The workspace manager is placed front and center, configured with four unique workspaces. An “LED” flashes to indicate a process is in work. A padlock icon launches a session display lock. The panel can be positioned anywhere on the desktop and be minimized or maximized with buttons on the panel ends. The package includes several backgrounds, screen-savers and desktop color schemes, making it easy to customize each workspace according to individual taste.
The CDE features several useful applications, including a multi-user planning calendar with drag and drop appointment scheduling and to-do items, a file manager similar to xfm, a simple text editor with spell checking, a MIME capable mail handler, a graphic printer manager, an application manager with numerous other utilities and the quintessential trash bin. There is even a Motif application builder for the programmer types. The multi-function calculator serves the financial, programmer and scientific users with the click of a button. Even the xterm is configurable on the fly.
To customize a control, one simply clicks on the icon with the right mouse button and then selects “Add Sub-panel” from the pop-up menu. The sub-panel is then ready to accept new application and utility items. Sub-panels and applications are removed in the same manner. The only drawback is additional controls have to be added by the system administrator by editing text files.
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
