Did Our Publisher Really Move to Costa Rica?
Looks like I didn't. Here I am, back in Seattle. But, when I got back from vacation (yes, in Costa Rica), one of the first questions I was asked was whether I had bought a resort in Costa Rica. My disappointing answer was no.
Why am I talking about this? Because, at COMDEX, a rumor was being spread that I had abandoned Linux for Costa Rica. Let me assure you I am not about to abandon Linux. I have been a UNIX geek since 1980, and got into Linux in 1993 because I saw it as a "better UNIX", which I still do. I started Linux Journal in 1994 because I believed in Linux. I still do, and I think we can all see that my early belief in Linux is now justified.
As there seemed to be concern about my "physical location" last month, let's talk about that. Linus didn't live in the U.S. when he began developing Linux. Should Remy Card and Miguel de Icaza not be counted as Linux developers because they don't live in the U.S.?
The whole reason Linux was able to happen is because communication channels exist such that people don't all have to be in the same place in order to work together. Six years ago, I wrote a futuristic editorial pretending it was January, 2000 and that I was working from Yaak, Montana (population 26). Certainly, I could be. Or I could be in Costa Rica. That's the advantage of communications technology, and in my case, print media that can be mailed.
If you don't believe this, check out the Amazing Arts Art Gallery. While I was in Costa Rica, I stayed at a small hotel called El Mono Azul (The Blue Monkey). The daughter of the owner may be on her way to becoming another Linus Torvalds. Janine, age 10, and one other 10-year-old have started a project to save the rainforest. Thanks to e-mail and the Web, it isn't just local. They are raising money through sales of crafts, buying land and starting an education program about the rainforest targeted at schools in the U.S. and worldwide. Communication available to everyone is what makes this possible.
Also while I was in Costa Rica, I saw an issue of PC Magazine in Spanish in a grocery store. It had a copy of Corel Linux bundled with it. Just made me think, "way to go". Whereas in the U.S. it is generally irritating to buy Microsoft software, it is a much bigger burden for someone in Costa Rica or any other country where people have less disposable income. I'm ready to help all of Central America convert to Linux.
If you are looking for me physically, I'm around. I will be giving a tutorial on "Programming without Perl" in Monterey in July, essentially covering how the shell, some shell commands and awk are valid tools for certain problems. I'll be at Usenix's Atlanta Linux Showcase in October. Lots of other shows are coming up. And, even though I was in Costa Rica for over two weeks this year, I have been here in Seattle a lot more of the time. Stop by Burk's Restaurant and I'll buy you a beer. Otherwise, I guess we can get back to virtual beers.
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
