    “It is not enough for code to work”*…

    It’s been said that software is “eating the world.” More and more, critical systems that were once controlled mechanically, or by people, are coming to depend on code. This was perhaps never clearer than in the summer of 2015, when on a single day, United Airlines grounded its fleet because of a problem with its departure-management system; trading was suspended on the New York Stock Exchange after an upgrade; the front page of The Wall Street Journal’s website crashed; and Seattle’s 911 system went down again, this time because a different router failed. The simultaneous failure of so many software systems smelled at first of a coordinated cyberattack. Almost more frightening was the realization, late in the day, that it was just a coincidence…

    Our standard framework for thinking about engineering failures—reflected, for instance, in regulations for medical devices—was developed shortly after World War II, before the advent of software, for electromechanical systems. The idea was that you make something reliable by making its parts reliable (say, you build your engine to withstand 40,000 takeoff-and-landing cycles) and by planning for the breakdown of those parts (you have two engines). But software doesn’t break… Software failures are failures of understanding, and of imagination…

    Invisible– but all too real and painful– problems, and the attempts to make them visible: “The Coming Software Apocalypse.”

    As we Code for America, we might recall that it was on this date in 1983 that Microsoft released its first software application, Microsoft Word 1.0.  For use with MS-DOS compatible systems, Word was the first word processing software to make extensive use of a computer mouse. (Not coincidentally, Microsoft had released a computer mouse for IBM-compatible PCs earlier in the year.)  A free demo version of Word was included with the current edition of PC World—  the first time a floppy disk was included with a magazine.

    “Your assumptions are your windows on the world. Scrub them off every once in a while, or the light won’t come in”*…

    In European societies, knowledge is often pictured as a tree: a single trunk – the core – with branches splaying outwards towards distant peripheries. The imagery of this tree is so deeply embedded in European thought-patterns that every form of institution has been marshalled into a ‘centre-periphery’ pattern. In philosophy, for example, there are certain ‘core’ subjects and other more marginal, peripheral, and implicitly expendable, ones. Likewise, a persistent, and demonstrably false, picture of science has it as consisting of a ‘stem’ of pure science (namely fundamental physics) with secondary domains of special sciences at varying degrees of remove: branches growing from, and dependent upon, the foundational trunk.

    Knowledge should indeed be thought of as a tree – just not this kind of tree. Rather than the European fruiter with its single trunk, knowledge should be pictured as a banyan tree, in which a multiplicity of aerial roots sustains a centreless organic system. The tree of knowledge has a plurality of roots, and structures of knowledge are multiply grounded in the earth: the body of knowledge is a single organic whole, no part of which is more or less dispensable than any other…

    As Krishna observed in the in the Bhagavad-Gītā, “stands an undying banyan tree.”  Explore it at “The tree of knowledge is not an apple or an oak but a banyan.”

    As we celebrate diversity, we might spare a thought for Douglas Carl Engelbart; he died on this date in 2013.  An engineer and inventor who was a computing and internet pioneer, Doug is best remembered for his seminal work on human-computer interface issues, and for “the Mother of All Demos” in 1968, at which he demonstrated for the first time the computer mouse, hypertext, networked computers, and the earliest versions of graphical user interfaces… that’s to say, computing as we know it.
