Fast Accurate Computation of Large-Scale IP Traffic Matrices from Link Loads |

Very cool ... A matrix giving the traffic volumes between origin and destination in a network has tremendously potential utility for network capacity planning and management. Unfortunately, traffic matrices are generally unavailable in large operational IP networks. On the other hand, link load measurements are readily available in IP networks. In this paper, we propose a new method for practical and rapid inference of traffic matrices in IP networks from link load measurements, augmented by readily available network and routing configuration information. We apply and validate the method by computing backbone-router to backbone-router traffic matrices on a large operational tier-1 IP network -- a problem an order of magnitude larger than any other comparable method has tackled. The results show that the method is remarkably fast and accurate, delivering the traffic matrix in under five seconds. Fast Accurate Computation of Large-Scale IP Traffic Matrices from Link Loads |

One hundred years ago next Wednesday, at precisely 2 pm, cheering citizens flooded the streets of Manhattan, creating a "carnival" atmosphere that had the city "in an uproar from end to end." The cause of celebration was the completion of the first section of the New York City Subway. For all the excitement on opening day, it didn't take New Yorkers long to revert to their jaded selves. This brief article on the history of subway technology brings David Macaulay to mind. Be sure to check out the illustrations. Looking Back As The New York Subway Turns 100 |

This study provides an analysis of the development of electronic networks in Europe and North America and their technical, economic and political drivers. It includes four scenarios depicting possible futures of electronic networks in Europe, a framework for policy formulation, analyses of selected current policies and observations regarding possible policy measures and the input of experts and stakeholders in the field during a workshop in Brussels. It concludes with a series of observations and recommendations for policy action and further research. The most interesting recommendation here is that copyrights should last about as long as patents. Evolution Scenarios for Future Networking Technologies and Networks |

Is Biotechnology Losing Its Nerve? |

Many biotechnology companies appear to be taking fewer chances lately -- to the point that the industry seems to have lost its nerve. More and more start-ups now seem focused on scrounging around ... "There's a fair question: Where's all the new stuff going on?" As big pharmaceutical companies have become even larger, they have concentrated on drugs with blockbuster potential rather than devote time to drugs with smaller markets. [Hmmm ... Where have I heard that story before?] I bet Norah Jones is popular at biotech firms, both as inspiration and as consolation. Is Biotechnology Losing Its Nerve? |

Can you count your friends? Better yet, can you organize them in a database? There's a lot of buzz about a new breed of software tools that can help people manage their contacts -- or, to make it sound more serious, leverage their social capital. "It's easy to identify candidates these days. The challenge now is selection." At the end of the day we will have private aggregations of data more rich and interconnected and personal than any government ever dreamed of ... and of course this data will be readily available, just as data from credit card companies, merchants and airlines is today. Finally, I have to ask what these tools do to the old, low-tech concept of friendship. In some way, with their numbers and lists and classifications, these services can subtly make a social network into a trophy collection. Technology has made it easier than ever to count your friends -- but that doesn't mean you should. Esther Dyson weighs in on the trends in social networking software.

The Fall/Winter 2003 issue of CIO Magazine is a special issue that focuses on "technology's impact on everything." They've assembled quite the team of contributors for this issue, including Ray Kurzweil, Her Majesty Queen Noor of Jordan, Bjorn Lomborg, Robert Reich, Howard Gardner, Jonathan Zittrain, Paul Saffo, Newt Gingrich, The Dalai Lama, Howard Rheingold, Robert Ballard, Barry Steinhardt, and more. Here's how the Barry Steinhardt piece begins: PICTURE THIS: You're attending a trade show in Las Vegas. Strolling around the city one evening, you happen upon a sex shop and pause for a moment to snicker at the curious items in the store's window. Then you continue on your way. However, unbeknownst to you, the store's Customer Identification System has detected a radio identification signal emitted by a computer chip in one of your credit cards, and is recording your identity and the date and time of your brief stop. A few weeks later, your spouse is surprised to find in the mail a lurid solicitation from the store mentioning your visit. You've got some explaining to do.

Most documents are the product of continual evolution. An essay may undergo dozens of revisions; source code for a computer program may undergo thousands. And as online collaboration becomes increasingly common, we see more and more ever-evolving group-authored texts. This site is a preliminary report on a simple visual technique, history flow, that provides a clear view of complex records of contributions and collaboration. IBM | History Flow |

The Pentagon's new terrorism futures market is suddenly a thing of the past. "It is a very significant mistake." "This Poindexter program is still a runaway horse that needs to be reined in." "It is totally unauthorized as far as we are concerned. It's really a serious mistake on the part of DARPA." Sound familiar? This meme just in: DARPA is the new AOL Time Warner, and John Poindexter is the new Justin Frankel. Terror Trading Site Goes Bust |
