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.

Free Webinar: Hadoop
How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.
Some of key questions to be discussed are:
- What is the “typical” Hadoop cluster and what should be installed on the different machine types?
- Why should you consider the typical workload patterns when making your hardware decisions?
- Are all microservers created equal for Hadoop deployments?
- How do I plan for expansion if I require more compute, memory, storage or networking?
