High Seas Adventure
The Caribbean's a great place to get geeky if you can keep the sand out of your laptop. Of the many cruises organized by Geek Cruises, this was the first one devoted to Linux. Linux Journal had the opportunity of cosponsorship, and it's something we look forward to repeating next year.
Besides being treated to intimate sessions and abundant chances for one-on-ones with some of the most prominent names in the Linux community, for us the cruise was a chance to get to know many of our readers (and even some of their families).
The geek sessions were balanced very well with time off in some fabulous ports of call—well, except Puerto Rico. But even there, Geek Cruise organizer, “Captain” Neil Bauman, arranged a special excursion for geek cruisers to see the home of the world's largest single-dish radio telescope, the Aricebo Observatory, where much of the movie Contact was filmed, and where scientists from around the world study things out of this world 24 hours a day, 365 days per year.
Of course we weren't so lucky in choosing the lunch restaurant that day. It was a buffet that ran out of food after half of us had made it through the line. Fortunately, the entertainment value of seeing Richard Stallman spill his soda (accidentally of course) on the world's largest baby who was sleeping in his playpen near the cash register was some compensation for my hunger. I couldn't help but laugh internally—the irony was too much, but I actually felt more sorry for Richard than the baby; he felt so badly about it. In some cosmic form of retribution my own two-year-old daughter spilled her soda (same flavor as Richard's) all over my lap, leaving me looking as if the excitement of the observatory was too much.
In contrast to Puerto Rico, the other ports of call were absolute representations of paradise. At our last stop, Holland-America's private island, Half Moon Cay, I rented a Sunfish sailboat with my eight-year-old daughter, Geneviéve. We sailed to the end of the bay and still could see straight to the ocean floor. For someone used to sailing the dark water of Washington's Puget Sound, it was a unique experience.
Next year's Linux Lunacy cruise is rumored to be planned for the Pacific, down Mexico way. Bring your sense of humor, your goodwill and join us!

Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
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
