Power Printing With MagicFilter
For real, actual word processing, I don't think you can beat Applixware, especially since its price just dropped to $199US a copy. As a matter of fact, I'm typing this article on the Applixware word processor. It's only officially supported on Red Hat Linux, but it works fine on Slackware 96, too. When installing, be sure to set your DISPLAY environment variable to:
On a 486 platform, commenting out Speedo and Type I fonts in the /etc/XF86Config file allows Applixware to load fast enough to prevent the X server connection from timing out. This tweak makes Netscape load much faster, too. Also on a 486, Applixware works in an X-only environment, i.e., restart /sbin/init at level 4 instead of the usual level 3. Finally, to run Applixware in general, have a whole lot of RAM.
To print a project with Applixware, push the print icon on the top menu bar and note the print dialog that follows. Just press on lp under “Printers”, set “Class” to PostScript (should already be there), make sure the “Print to File” button is not pressed and click OK. With MagicFilter installed, Applixware should literally print right out of the box. Figure 2 shows how the print dialog appears just before printing.
Ordinarily, printing a .tex file is a three-step procedure. First, you run tex on the .tex file, then dvips on the .dvi file and then ghostscript on the .ps file. With MagicFilter, you just run TeX or LaTeX on your document file, shoot the resulting .dvi file straight to lpr and let MagicFilter handle the rest. One caveat here—if the .dvi file contains references to PostScript figures, you must run dvips manually and send the generated .ps file to lpr. Since the default for dvips is to send the output to the printer, you can simply think of it as running dvips to send the document to the printer. This is not a MagicFilter flaw, but rather it's a “miss-feature” in the way .dvi files handle embedded PostScript.
After using MagicFilter for a while, I thought it would make a great addition to commercial Linux packages as part of their initial installation. But on second thought, this would be easier said than done, given the many kinds of printers and file formats we have today. One of MagicFilter's strong points is the fact that it is tailored to your personal system, printer and printing needs. To try to integrate it into a distribution's installation process might turn out to be counterproductive. MagicFilter and its supporting packages are easy to build, and they're readily available. It's probably best to leave things the way they are. If you've never compiled software on your own system, MagicFilter makes a great first project and could be a big confidence builder for a new Linux user.
Brian McCauley makes the point in the Linux Printing-HOWTO that MagicFilter prevents the user from printing a listing of, for example, a binary file, and he's right. However, I think most people would prefer to turn off MagicFilter, if this situation ever came up, print the listing and turn MagicFilter back on. It just makes life so much simpler.
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
