Focus: Science & Engineering
New technology has always found a home in the science labs of universities and the research departments of both scientific and engineering companies. Schools and new companies looking for their niche in the marketplace often have restricted budgets and a need for highly robust systems. For both these reasons, Linux has been embraced from the beginning by research departments in universities, business and government.
I have always had in interest in science. My degree is a B.S. (math and physics), one of my hobbies is astronomy, my job for many years was programming geophysical applications, and my husband is a physicist. As a result, our Science & Engineering issue is always one of my favorites. I enjoy reading about the cool ways Linux is being put to use in these fields. And this issue is no exception—we even have an article about geophysics.
Ed Petron's article on teaching computers to think brings science fiction to everyday reality. This new method of programming is a quite a step from the usual algorithmic approach. Speaking of science fiction, take a look at the pictures of Fermilab and the great article by Jon Hall.
Inside, Wolf-Rainer Novender describes SCEPTRE, a simulation tool for electric circuits, and on the Web, Alasdair McAndrew gives us a comprehensive tutorial for the mathematical tool, MuPad. Also in “Strictly On-line” are articles about using GPS technology to do precision farming and calculating underground water quality using parallel algorithms. Two unique uses of Linux that I would never have dreamed up.
As long as students continue to be exposed to Linux at school in their science labs, Linux will continue to make inroads into engineering and scientific applications.
Ransom Love of Caldera dropped by our office in April to give us a copy of their new release, OpenLinux 2.2. I installed it on a test machine to see if the much-touted “new and easy” Lizard install truly worked. Basically, it did, but I had one problem: the install was hanging while probing for the SCSI device, a 2-channel UW Adaptec on-board controller. A message from Caldera support recommended I use the boot parameter er=cautious. I did, and it worked. I also had to use the custom install option and define partitions, since the machine I was using already had the Be OS installed. If the OS had been Windows, Lizard would have automatically built the partitions using PartitionMagic. Even with the custom install, the entire procedure took about ten minutes and I had a working Linux system with KDE, WordPerfect8, Star Office and other goodies. It was so fast, that by the time it offered to let me play Tetris, the installation was complete. When Linux detractors say Linux needs an easy install, this is what they want. We'll have a full review next month.

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
