What causes a slow directory lookup speed on a hard drive?

That’s pretty common in hardware design. If a signal comes out of some device in a “high” condition when you might have preferred a “low”, rather than interposing an additional circuit to flip it, it is just labeled accordingly and the logic adjusts. To a computer, a double negative isn’t a problem.

Right, although: (1) this is software, with no cost ramifications and (2) the very word Disable not only confuses the issue, but is entirely unnecessary.

I realize this complaint shows more of my OCD/pedantic/neurotic side than I might like, but as someone who has agonized over…well, OK, spent maybe 10-15 minutes :)…over proper variable naming (is it too long? does it adequately express its use? am i following the standard? right polish or left polish notation?), it bugs me. It’s not always a good trait, but one of my pet peeves is poorly written code, even at this level of detail.

I couldn’t agree with you more, but I don’t think the average software designer has near those deep ethics or agonizes for very long over what to call a parameter.

Too bad, because whatever was dashed off quickly without much thought may become imbedded and permanent for years.
