Setting the mood for this month's issue is our cover photograph of Mark Hansen and Ben Rubin's Listening Post, currently featured at the Whitney Museum of American Art in New York (www.whitney.org). This remarkable installation runs on four computers and as many operating systems (including Linux, of course) and expresses the collective voice of the Internet, transforming on-line communication into a multimedia installation.
According to the Listening Post web site, “statistical analysis organizes the messages into topic clusters based on their content, tracking the ebb and flow of communication on the Web. A tonal soundscape underlies the spoken text, its pitches and timbres responding to changes in the flow and content of the messages.”
I was lucky enough to “view” the Listening Post when it was in Seattle in November 2002, and my first impression was an almost eerie sense of humanness the piece unveils—a poetry not typically associated with computer technology. In a dark room complete with pillows on the floor, a wall of tiny screens depict glowing green text gathered in real time from thousands of public on-line communication channels. These bits of text are accompanied by a computer-generated voice with a British accent, randomly speaking different messages as they flash by. I was particularly struck by the “I am” series; real-time messages beginning with the string “I am” spoken into the darkness: “I am tired.” “I am happy.” “I am Norwegian.” Hundreds of people communicating the most basic aspects of themselves at that precise moment from who knows where to who knows who, while my imagination worked double time wanting to fill in the rest of their stories.
Capturing the ephemeral nature of the Listening Post is difficult; however, Ben Rubin, one of the creators of the Listening Post, best describes the piece in his artist's statement:
Anyone who types a message in a chat room and hits “send” is calling out for a response. Listening Post is our response—a series of soundtracks and visual arrangements of text that respond to the scale, the immediacy and the meaning of this torrent of communication.
Every word that enters our system was typed only seconds before by someone, somewhere. The irregular staccato of these arriving messages form the visual and audible rhythms of the work. The sound-generating systems are constructed almost as wind chimes, where the wind in this case is not meteorological but human, and the particles that move are not air molecules but words. At some level, Listening Post is about harnessing the human energy that is carried by all of these words and channeling that energy through the mechanisms of the piece.
Listening Post represents the most significant outcome so far of my collaboration with Mark Hansen, the only artist I know whose medium of expression is statistics. Since we began working together, my conceptual vocabulary has grown to include notions like clustering, smoothing, outliers, high-dimensional spaces, probability distributions, and other terms that are a routine part of Mark's day-to-day work. Having glimpsed the world through Mark's eyes, I now hear sounds I would never have thought to listen for.

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
