Visit to a Strange Program
I realize it is a little bit bizarre, François, but part of what makes running Linux so attractive is it has put the fun back into computing. Sometimes fun is just plain silly. Non, mon ami, this program does nothing for your productivity. No, it does not monitor resources nor help with system administration. Yes, you are correct, it serves no obvious useful purpose.
You ask why? Why, François, do we serve fine wines and not plain water? Why do we indulge in rich foods and decadent desserts rather than consuming only what our bodies need? Because it is fun, mon ami. And why are you not paying attention to me? What are you looking at?
Ah, bonjour, mes amis! Welcome to Chez Marcel, home of fine Linux fare, great wine and the occasional excursion into strange and unusual software territory. Please sit and François will pour the wine immédiatement. François, to the wine cellar. Fetch the 1997 Eden Valley Hill of Grace Shiraz. Vite!
As you know, mes amis, the focus of this month's issue is program development. The obvious approach is to showcase some of the marvelous tools used by talented open-source programmers to improve and enrich the Linux landscape. It is on that note that I would like to point out the following: sometimes, those talented programmers are simply playing, having a bit of fun. Sometimes, the programs they turn out are silly, bizarre and, occasionally, plain weird. Those are the people I wish to honor with today's menu.
Once upon a time, ASCII art was practiced in e-mail messages sent around the world. Unfortunately, fancy fonts and HTML-ized e-mails have struck a powerful blow to this ancient and noble art form. The most missed are probably the cows, for Tony Monroe, anyhow. His cowsay program (a nice, easy-to-play-with Perl script) provides a simple way to generate an ASCII cow that speaks your message. Head on over to www.nog.net/~tony/warez/cowsay.shtml to pick up your copy and extract it into your directory. The installation consists of running an install.sh file. Running the program also is quite simple. Let's pretend that I want a cow saying “More wine, please”:
$ cowsay More wine please. ------------------- < More wine please. > ------------------- \ ^__^ \ (oo)\_______ (__)\ )\/\ ||----w | || ||
With the -e and -T options, you can define the cow's eyes and tongue. You also can use the -f option to specify any of the other animals (or cow-like creatures) in the /usr/local/share/cows directory. You'll even find Tux there. Be warned, however, that some of the art can be a bit off-color.
Talking milk carton, anyone?
In the world of programmed silliness, a lot can be said for words. Text, that is. Take, for instance, Andy Gilligan's cack program for generating nonsensical phrases (sourceforge.net/projects/cack). “So, how would you use cack?” you may find yourself asking. Say, for instance, you are trying to answer an e-mail, and you need something totally nonsensical to make your point. It's cack to the rescue. Simply type cack followed by a number to represent how many lines of nonsense you wish to generate, then press Enter. Here is an example of what you can expect:
disintegrate the 95 marauder and the on request medieval eel billet the unsized aged and the biochemically amphiprostylar crotchetiness
Your friends will think you are either crazy or brilliant.
To take this up a notch, you may want to check out the aptly named nonsense. In essence, nonsense is a clever generator of, well, nonsense. For instance, with the command nonsense -f mission.data, you can generate corporate mission statements like this one:
Our mission is to achieve progress in integrating integrated technologies to produce more revenue for our head honchos and make our founder enough cash to exceed the net worth of the world's richest man.
For nonsense, this is quite a flexible program. With command-line switches, you can make nonsense generate business plans, strange names for people, imaginary political organizations, an impressive geek resume (Figure 1), bizarre laws (“It's a Class C felony in Yellow Walnut, Michigan, to hit a poison ivy plant with a cardboard box”), newspaper headlines (“Computer Possessed By Satanic Dæmon”) and even a pretty realistic Slashdot web page. Some of the output is in HTML format and is suitable for web pages—all silly, of course. The many other options and their results may well keep you busy for hours.
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
