There are two common points of view about Linux in the so-called enterprise. The first is that Linux is only capable of displacing Microsoft products on cheap low-end servers, and that proprietary UNIXes with their huge 64-bit address spaces and big SMP scalability are safe. The second is that Linux is mainly displacing UNIX, since it's easy to port software from UNIX to Linux, and that Microsoft with its difficult-to-port-from APIs is safe.
Both points of view are wrong. Nothing is safe. On page 44, Linux is running on a new 64-processor NUMA system. And, on page 52, Linux is displacing the nastiest Microsoft server to replace, Exchange—undocumented protocols and all.
In our December 2002 issue, Douglas B. Maxwell wrote about how he beat the graphics performance of a large SGI system with $15,000 worth of PCs. This month, we're celebrating SGI's release of a big Linux box by putting it on our cover. Do we have the world's shortest attention span? Aren't generic PCs taking over everything?
If they are, they're not done yet. If you have a big problem that you haven't figured out how to split into PC-sized chunks, or don't want to take the time to split into PC-sized chunks, the 512GB of memory on the new SGI Altix 3000 seems like just what you need.
One slogan at SGI is “do science, not computer science”. Do big problems the way you know how and get better results now. Of course, this is waving a red flag in front of the commodity cluster faction, and I'm sure we'll soon have plenty of articles pointing out how you can get previously unclusterable work done on a cluster.
The diversity of success stories in this issue makes it clear that any company that tries to compete with Linux in a fair fight will lose. So it's going to be an unfair fight for a while, with the non-Linux vendors pulling shenanigans such as bogus software patents, FUD-based marketing, copy-restricted content, carefully placed “donations” and “campaign contributions”, and who knows what else.
But most of the companies, and most important, the people, who are promoting non-Linux legacy products today are going to be part of the Linux business tomorrow. Since our community will survive and theirs won't, ours has to be able to welcome and do business with them in the future. So we can't engage in the same desperate nonsense they are. All we have is the best software and the truth, and that's plenty.
Finally, the one enterprise that's most important to pulling some people from just getting by up to knowledge and success is the public library. Your local library provides educational materials, entertainment, training and community programs. Now, that important institution's budget won't be wasted on expensive, inflexible proprietary software. The Koha Project is offering library cataloging and search software under the GPL, in the same spirit we have public libraries in the first place. Join your local Friends of the Library and read Pat Eyler's article on page 58.

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
