  • Lots of great inventions seem obvious in retrospect….

    “Lots of great inventions seem obvious in retrospect. About 30 years ago, one of our clients realized that if you attach a small pom-pom to the back of a short tennis sock, the sock won’t slip down into your tennis shoe.

  • Net neutrality and real-time

    British Telecom breaks with the party line. This is the intersection of a business/political dispute about what business telecos should be in and a technical issue of QOS. Traffic shaping is a blunt instrument for QOS and part of the problem is that nobody bothers to try to characterize scheduling requirements more precisely than “needs…
