Turning SF's Bay Bridge Into a Giant LED Display 99

waderoush writes "It may be the biggest art hack ever: a project to install 25,000 individually addressable LED lights on the western span of the San Francisco-Oakland Bay Bridge. New York-based 'light sculptor' Leo Villareal was in San Francisco last week to test the vast 'Bay Lights' art installation, which will officially debut on March 5 and last for two years; Xconomy has photos and video of Villareal running the light show from his laptop. To optimize his algorithms and figure out which patterns would be most interesting or arresting, Villareal needed to experiment on the bridge itself, says Bay Lights director Ben Davis, who has raised $5.8 million for the project so far. 'This has never been done before in history — literally debugging software 500 feet in the air, in front of a million people,' says Davis."

    If that's great art, the Christmas lights at my local pub were a fucking timeless masterpiece.

    Origin of the term 'debug', from wikipedia:

    There is some controversy over the origin of the term "debugging".

    The terms "bug" and "debugging" are both popularly attributed to Admiral Grace Hopper in the 1940s.[1] While she was working on a Mark II Computer at Harvard University, her associates discovered a moth stuck in a relay and thereby impeding operation, whereupon she remarked that they were "debugging" the system. However the term "bug" in the meaning of technical error dates back at least to 1878 and Thomas Edison (see software bug for a full discussion), and "debugging" seems to have been used as a term in aeronautics before entering the world of computers. Indeed, in an interview Grace Hopper remarked that she was not coining the term. The moth fit the already existing terminology, so it was saved.

    The Oxford English Dictionary entry for "debug" quotes the term "debugging" used in reference to airplane engine testing in a 1945 article in the Journal of the Royal Aeronautical Society; Hopper's bug was found on September 9, 1947. The term was not adopted by computer programmers until the early 1950s. The seminal article by Gill [2] in 1951 is the earliest in-depth discussion of programming errors, but it does not use the term "bug" or "debugging". In the ACM's digital library, the term "debugging" is first used in three papers from 1952 ACM National Meetings.[3][4][5] Two of the three use the term in quotation marks. By 1963, "debugging" was a common enough term to be mentioned in passing without explanation on page 1 of the CTSS manual.[6] Kidwell's article Stalking the Elusive Computer Bug[7] discusses the etymology of "bug" and "debug" in greater detail..
