Re: Slow network?

Waiting for a response after each send will take longer than doing the sends and then the responses. Have you tried pinging the destination to see how long the round trip takes? Has your friend? My test application listens on 127.0.0.1. gand...@gandalf-desktop:~/Python/Lib/orb/examples/01_

Re: efficient interval containment lookup

suppose I have two lists of intervals, one significantly larger than the other. For example listA = [(10, 30), (5, 25), (100, 200), ...] might contain thousands of elements while listB (of the same form) might contain hundreds of thousands or millions of elements. I want to count how many interval

Re: efficient interval containment lookup

Are these ranges constrained in any way? Does preprocessing count in the efficiency cost? Is the long list or the short list fixed while the other varies? With no constraints the problem is harder. > But perhaps there's a way to index this that makes things more > efficient? I.e. a smart way of
