Cooking with Linux - Because Nothing Says High Performance Like a Good Race
Repeat what you just told me, François. No! Don't tell me that! Yes, François, I know I told you to repeat what you told me, but I was sincerely hoping I was mistaken and that I had heard something entirely different. Something like, “Patron, I lost the key to the filing cabinet”, not, “I lost the key to the wine cellar.” In my first restaurant job, François, this would have been considered a firing offense. No, mon ami, I am not going to fire you, but this is terrible! What shall we serve our guests?
Non! I see them walking toward the restaurant now. Quickly, François, think of something. Why you? Because you locked up the wine cellar minutes before opening time, then proceeded to lose the key. That's why. Quoi? Serve beer from my personal réfrigérateur de bière? That is not a bad idea at all, mon ami. You live to serve another day, non? Don't look so hurt, François. We have guests. Quickly!
Ah, welcome, everyone, to Chez Marcel, where fine Linux fare is served with the most excellent wines from one of the world's premier wine cellars—that is, except tonight. It seems my faithful waiter has lost the keys to the wine cellar. Never fear, mes amis, though I love that wondrous liquid fruit of the grape, your Chef also enjoys a good beer, be it lager or ale. So, tonight's menu will be accompanied by selections from my own réfrigérateur de bière. Please, sit and make yourselves comfortable. François can offer you several excellent selections, all favorites of mine, including Alexander Keiths' India Pale Ale, Kilkenny Irish Cream Ale, Sleeman's Original, Unibroue Maudite and several others.
As you know, mes amis, this issue's theme is high performance, which we all know can refer only to racing and automobiles. If the words high performance and Linux don't immediately generate the same association in your mind, you should know that in point of fact, Linux and car racing go very well together. The 2007 Indianapolis 500 featured the first ever Linux-sponsored car. The brainchild of Ken Starks, aka helios, the Tux500 Project succeeded in its aim to raise enough money to place Tux, the familiar Linux mascot created by Larry Ewing, on the hood of an Indy car. For more details, go to www.tux500.com.
In honor of this momentous event, the first race game on tonight's menu, SuperTuxKart, features the very same Tux at the wheel. SuperTuxKart, maintained by Joerg Henrichs, is an updated and enhanced version of the original TuxKart, created by Steve Baker. If you've played the original, you'll be impressed by the new, hugely improved, SuperTuxKart. The game features slick new graphics, new tracks, cool characters, racing adventures and more. You take the controls as one of several characters, including Tux, Penny (his friend), Mr. Ice Block, Sushi the Octopus (Figure 2), Yeti and others. You can get SuperTuxKart from supertuxkart.berlios.de.
Your next step is to choose whether you want to race on your own (for practice) or enter a race with other players. These can be other humans (masquerading as SuperTuxKart characters, of course), or they can be computer AI players. Once your cast is assembled, it's time to select a race type and course. You can indulge in a Grand Prix event that takes you through all 13 courses, a handful, or simply go for a single race and select a time trial.
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
