And Now for Something Completely Different...
Linux Journal employees have been fans of Python for some time. Many of the scripts we use daily are written in Python. Our publisher, Phil Hughes, likes it so much he reads every Python book published. (He reviews three of them in this supplement.) Combining that fact with the exploding popularity of this clean, robust language, we decided it was time to provide our readers with a supplement dedicated to Python.
Wait, what's this? A bridge and its keeper wanting us to answer three questions before continuing. Well, I'll go first—how hard can they be? You follow.
Wha-at! is your name? Marjorie of Richardson
Whe-re! are you from? Seattle in Washington
Wha-at! is your favorite programming language? FORTRAN—No! Python—Too late! Aaaaaaah!
Those easy ones get me every time, but I'm sure you will do better. Give it a try and if you miss any, consider yourself thrown into the ravine with me.
The answer to number three should, of course, be Python. If something else, you might not want to continue unless you are actually searching for that holiest of grails—the perfect scripting language. The worst and only complaint I've heard about Python is the required tabs, and everyone gets used to those in fairly short order. After all, most programmers use them anyway to ensure a readable format for their code. On the other hand, it's easy to learn, easy to write, easy to understand—in other words, perfect!
We have plenty for you to enjoy this month: programming articles, book reviews and articles by Guido van Rossum and Eric Raymond. Guido tells us how he envisions Python will be used in the future to teach programming in schools. Eric tells us why Python is now his favorite language (he made it across the bridge!) and why he uses it instead of Perl in much of his programming. And don't forget, the Linux Journal's focus this month is Programming, and there's a great article in the main issue about embedding Python in multi-threaded C/C++ programs—not to be missed. There are even two Python articles in “Strictly On-line” at http://linuxjournal.com/.
Just in case you're wondering about all the silliness, Guido van Rossum, the creator of Python, is a big fan of the Monty Python series and named the language after it. Thanks to Jason Schumaker for posing as a nude hacker for our Pythonesque cover. So, those of you who made it across the bridge can now proceed in learning more about this wonderful “Monty Python” of programming languages. That is, don't run away—stay and have fun (nudge nudge, wink wink). We promise not to make any dead parrot jokes...

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
