On the Humble Default

Hugh Pickens sends along Kevin Kelly's paean to the default. "One of the greatest unappreciated inventions of modern life is the default. 'Default' is a technical concept first used in computer science in the 1960s to indicate a preset standard. ... Today the notion of a default has spread beyond computer science to the culture at large. It seems such a small thing, but the idea of the default is fundamental... It's hard to remember a time when defaults were not part of life. But defaults only arose as computing spread; they are an attribute of complex technological systems. There were no defaults in the industrial age. ... The hallmark of flexible technological systems is the ease by which they can be rewired, modified, reprogrammed, adapted, and changed to suit new uses and new users. Many (not all) of their assumptions can be altered. The upside to endless flexibility and multiple defaults lies in the genuine choice that an individual now has, if one wants it. ... Choices materialize when summoned. But these abundant choices never appeared in fixed designs. ... In properly designed default system, I always have my full freedoms, yet my choices are presented to me in a way that encourages taking those choices in time — in an incremental and educated manner. Defaults are a tool that tame expanding choice."

  1. Pre-1950 systems with configurable defaults. by Animats · · Score: 4, Informative

    I'm trying to think of something prior to 1950 that had an overridable, configurable default. It's hard. Business telephone systems had some configurable defaults, but setting them up required physical wiring. The same was true of Plan 55-A Teletype message switching. IBM plugboard-wired tabulators didn't really have defaults as we think of them today. Machine tools had adjustable speeds and feeds, but no real defaults. Jacquard looms didn't have defaults. Linotypes didn't have defaults. Chain-programmed embroidery machines - no.

    The closest thing I can think of was General Railway Signal's NX signaling system for controlling railroad interlockings. This 1930s system may have been the first "user-friendly interface". An NX system controlled multiple switches and signals in an area (an "interlocking") preventing conflicts. Interlocked signal controls had been around for years, and they handled the safety issue, but before NX, it was the user's responsibility to figure out the desired path from A to B. With an NX system, you selected an "entry" point where a train was going to enter the interlocking, and all the reachable "exit" points would light up. The "reachable" logic took into account other trains that were in the interlocking area. When the operator selected an "exit", the NX system would pick a path between the entry and exit, routing around other trains or even track locked out of service.

    A default "best" routing was hard-wired into the system, but the operator could override the default routing manually, by picking some intermediate point along the path as the "exit", then selecting that as an "entry" and picking the final "exit".

    That's the oldest system I know of with a real "default" mechanism.

  2. Re:A good translation for default to other languag by gzipped_tar · · Score: 3, Informative

    Quite easy in Chinese. Since /. is too US-centric to tolerate Unicode, I'll just post the Unicode codepoints for these two characters: U+9ED8 and U+8BA4. Look them up in a Unicode table ;)

    This Chinese word for "default", in a more literal translation, means "tacitly accepted/recognized". It has nothing to do with the financial meaning of the word "default", which translates to a completely different word in Chinese.

  3. This is bull by LS · · Score: 4, Informative

    But if you are looking for another computer word that has made it into common usage, how about "reboot"? It's now used to describe starting anything over from scratch, especially in things like movies. For instance, the new Star Trek movie has been called a reboot by several movie critics.

    I can imagine a time far in the future where "reboot" is listed in the dictionary with the etymology saying "origin unclear, borrowed from computer terminology". 95% of people will not know that it comes from the REpeating the action of BOOTstrapping a computer. Bootstrapping or booting a computer comes from the term "to lift oneself up by the bootstraps", which is impossible and refers to the apparent chicken and egg problem of a computer loading itself up with software.

    Yes, because those things are evil, and soon result in huge piles of nested font tags and random stylesheet fragments everywhere.
