comment Efficiently Visualising Very Large Data Sets (without running out of memory)
It "gags" because you have about 2GB of results and are trying to render them in the front end. I suppose I don't see how you hope to gain anything by seeing the full output. Try a small problem and verify that it works. Look at a subset of individual results. Check that the dimensions are what you expect etc..

comment Efficient way to generate random points with a predefined lower bound on their pairwise Euclidean distance
@Yves That would be yet more fun.. at least when animated we see this to some extent based on their relative laziness :)

@rcollyer they weren't doing anything incorrectly but they requested a solution that only used MousePosition a single time.

comment Locators and Table within a Manipulate are not behaving
I'm glad you figure this out, it was driving me crazy :) I'm keen to hear an explanation for why this worked as well. I had tracked the problem down to theta2 in the Table but I couldn't seem to fix it.

You should file that as a suggestion to WRI if you haven't already.

comment List all the directories under the current one
Yes, that is what I was referring to. I had a vague idea about using command line input in other places, I didn't realize it worked here as well. Potentially a very powerful idea.
