World Domination Swings through Costa Rica
We talked a little more, and he suggested that if I was willing to speak, they would do some promotion and see if they could stir up additional interest. I said sure and suggested a talk about why world domination with Linux makes sense.
I arrived in CR on June 6 and spent some time being a tourist. The meeting wasn't until Saturday, June 30, and all seemed under control. Juan said he was going to contact people at the Ministry of Science and Technology to see if someone there might be willing to attend.
Well, things really got rolling. Guy de Téramond, the Minister, is seriously into Linux. Soon the meeting had speakers scheduled from the Costa Rican government and an ad in La Nacion, the biggest daily paper in Costa Rica.
The publicity paid off. In a beautiful auditorium at Universidad Latina, we managed to attract a crowd of about 200 Linux enthusiasts and people who just wanted to know more. The event included simultaneous Spanish and English translation and went off very well.
The first talk was titled "An Introduction to Linux and Free Software" and was given by Juan Ignacio Del Valle and Alexis Maldonado from the University of Costa Rica. It was a good intro for the newcomers. Next, Mario Guerra spoke on how he had developed a system using Linux and the PostgreSQL database to allow on-line public lookup of polling places.
The first half of the meeting ended with a talk by Jose Freddy Rojas Chavarria of ICE, the electric/communications utility. He discussed SCADA systems and Linux control applications.
After a break I spoke on world domination, followed by Guy de Téramond's discussion of the future of open vs. proprietary software and its implication in the educational process. After the meeting there was a small get together for the speakers and GULCR members who planned the event.
All in all, the meeting went off quite well, and I really enjoyed being part of it.
In recent e-mail with Mario Guerra, I have learned that another event is planned for Puntarenas, a province on the Pacific coast of Costa Rica. With a lot of hard work on the part of the GULCR members and serious government interest, I feel that Costa Rica is well on its way to being on the Linux side of the world domination scorecard.
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
