- This has been kind of a fun discussion to watch.
-
- I don't have anything useful to contribute, but some of this discussion made me
- think of a little anecdote:
-
- About a year and a half ago, the entire local phone system in the Washington,
- DC area went down. Totally. For about a day and a half. Thoroughly messing
- things up around here. As I remember it, this coincided, within a couple days,
- with similar outages in several other major cities. The problem was traced to
- switching equipment manufactured by DSC Communications (which, by the way, is
- centered in Plano, Texas, my hometown).
-
- Seems DSC had just sent out a small update to the software that runs their
- switching equipment. It patched one line of code (some newspaper accounts said
- one BYTE). Apparently that single change had a bug in it that would cause the
- whole shebang to overload and shut down under certain conditions.
-
- When I read about the cause in the paper, my first thought was "Oh, boy, heads
- are rolling in Plano!" My second thought was that the poor programmer who
- authored the fix probably wasn't in any trouble at all. The guy who lost his
- job was undoubtedly the manager who said "This is such a tiny fix, it doesn't
- need to go through QA!"
-
- A word to the wise is sufficient...
-
- Just the same, Dave Every's "Use at your own risk" solution sounds like a
- pretty good way to go.
