One of the major parts of one math course I took was power series. One such equation done with Mathematica is shown in Figures 4 through 6.
This is just the tip of the iceberg in regard to the many mathematical equations you can perform with Mathematica. You can also program Button Boxes to perform specific actions when you click on them. This option enables you to create interactive worksheets (see Figure 7). Other capabilities include sound, animation and transforming input files (such as an image file) or external sounds. Mathematica's language can be used to read in files, output to files, read directory contents (explicitly and type-globbing), change to a different working directory and delete files, all of which I found to be quite useful. Any programmer will appreciate the Mathematica feature that converts a Mathematica expression to a C or FORTRAN expression—an extremely useful feature (Figure 8).
Mathematica has an external function which converts Mathematica worksheets to HTML or TeX.
I tested the HTML conversion, and it basically produced an HTML document with links to images containing all of the worksheet contents, both text and graphics (see Listing 1). Output from Mathematica can be sent to an external file, or one file can be combined (spliced) with another. External commands can be launched from Mathematica, e.g., to start Netscape or any one of the various word processing packages.
Mathematica is an excellent tool with limitless features. I was impressed at how smoothly it ran with both Netscape and StarOffice running at the same time. I truly wish this had been available when I was in school, not only because it is available for Linux, but because of all the useful features and the fun I have using it. I like the flexible language Mathematica uses, and the documentation is excellent. I found The Mathematica Book to be full of great examples and explanations on usage. Best of all, it runs on Linux and takes full advantage of Linux's speed, both in computations and graphics rendering.
Users of this product could be engineers, scientists, chemists, teachers, students and general math enthusiasts. I highly recommend Mathematica to anyone who is involved in the sciences. This is one tool you will always find invaluable, and it is well worth the price.
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
