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.

Today’s modular x86 servers are compute-centric, designed as a least common denominator to support a wide range of IT workloads. Those generic, virtualized IT workloads have much different resource optimization requirements than hyperscale and cloud applications. They have resulted in a “one size fits all” enterprise IT architecture that is not optimized for a specific set of IT workloads, and especially not emerging hyperscale workloads, such as web applications, big data, and object storage. In this report, you will learn how shifting the focus from traditional compute-centric IT architectures to an innovative disaggregated fabric-based architecture can optimize and scale your data center.

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6
Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.

Free Webinar: Linux Backup and Recovery
Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.
In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
