More Than Word(s)
As I have mentioned repeatedly, the information contained within the majority of documents is plain text. At times some fancy formatting may be nice, but it's optional. The main interest of the person writing the document should be to communicate the information.
Simple, plain ASCII text is usually sufficient to send information from one person to another—that's exactly why e-mail, for example, is still a text medium. HTML in e-mails does not add anything to the content. ASCII text can be read from anywhere with any editor (and not just with “any editor, including Microsoft Word...”). By structuring the text clearly, by using paragraphs and horizontal lines constructed out of hyphens, maybe even by using *bold*, /italics/ and _underlined_ text as used on Usenet, one can write clear, easy-to-read and understand and, most importantly, portable documents.
While plain ASCII text should be the choice for most cases, it cannot be denied that occasionally one might need or want more formatting. Well, no need to dig out the old word processor again. Just use LyX, the graphical front end to LaTeX.
LaTeX is an astounding typesetting engine derived from TeX. It takes a .tex file as input and typesets it, generating a .dvi file. It is available for a large variety of platforms, and documents typeset with LaTeX look incredibly professional. Yet, you can use your favorite editor to create the input files because LaTeX is a command-line tool.
When using LaTeX, one can concentrate on the content of the document instead of the way it looks because the typesetting engine will take care of the layout. A .tex file contains a few tags (which may remind you of HTML) to determine the way the text will be displayed.
This is a completely different way of writing a document from word processors; no more pointing and clicking and highlighting and reconsidering and so on. But, it may be daunting to someone who is used to using a GUI.
Now this is where the good guys from LyX come into play. They developed a GUI for LaTeX, enabling the inexperienced user to take advantage of the power of TeX without having to learn it from scratch (yet).
Upon first glance, LyX may look similar to your average word processor, but if you follow the tutorial, you will quickly see the difference and how you can increase productivity by concentrating on your work and material, rather than on the visual representation.
If you often connect to your machine remotely to get work done, you don't always have the ability to export your display or to forward X. This is when you learn to appreciate the power of the command line—you find that everything you will ever need is right there at your fingertips. By using your favorite editor (vim, in my case) and LaTeX, you can get all your work done easily through a single terminal to your machine.
Another advantage of LyX and LaTeX is that you can easily export your files into platform-independent formats such as PostScript or PDF. By combining the power of make with the power of LaTeX, this can be done with just a few commands. Take, for example, this document—I turned the input file into a beautiful PDF (Figure 4) simply by using the command make pdf.
Even though the Makefile itself (see Listing 1) is simple, it allows me to convert my document easily into a large variety of output formats using several different command-line tools, such as ps2pdf and latex2html.
Finally, LaTeX is extensible—you can write your own styles to achieve different results depending on the kind of document you are writing. But most likely, someone else has already done so and uploaded it to the Comprehensive Tex Archive Network (CTAN, TeX's equivalent to Perl's CPAN).
In brief, whichever way you choose to handle your word processing, the importance of conveying the information in a portable document format needs to be expressed. Just try to make it clear to the people with whom you correspond, to the people who continually send you MS Word documents and then insist that you “fix your computer” when you tell them that you can't open them or that some formatting got lost. I have found that if one explains in a friendly way how a PDF or a PS, for example, can be read by anyone on almost every platform, occasionally one can educate all but the most stubborn citizens of Winworld.
Personally, I'm sure you will find that LaTeX is far superior even for these little everyday tasks when it comes to creating professional (looking) documents. In order to take advantage of LaTeX, however, it is necessary to free your mind from what you may be used to. This may take awhile, but don't be afraid, there is a lot of helpful documentation out there. Maybe the most important document for a LaTeX beginner might be “The Not So Short Introduction to LaTeX2”, available from Comprehensive TeX Archive Network (www.ctan.org).
After a short time of going through a tutorial and, most importantly, giving it a try and taking a look at some examples, you will never want to go back. You can take my Word for it.

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
