comment Is there a way to get AbsoluteTime to correctly report absolute time differences?
@alancalvitti: I've tried. They got defensive and angry. Very unpleasant experience.

The question is how to get AstronomicalData to report the "total number of seconds" between two dates, as claimed; not how to calculate them on one's own.

@rcollyer: Thanks! And if you have any ideas on how to get Wolfram's "Support" to work, let me know.

@rcollyer: No further interest from Mathematica ("Premier") "Support" other than to blame the mouse.

@Nasser: Yes, that's annoying (though I bet some IDEs play that way too).

comment Selection bugs make Mathematica 10 unusable
@rcollyer: Wolfram's "support" explains: "This sounds like a dirty track pad or a faulty mouse." FWIW: I didn't see selection or responsiveness issues in ANY other applications, and removing caches fixed the issue (for now).

How does this relate to LinearSolve[tmat - DiagonalMatrix[Join[Table[1, {n - 2}], {0, 0}]], Append[Table[0, {n - 1}], 1]] (from the original question)?

comment Can I use 'ItemStyle' in 'Grid' to specify the style of individual items?
@MikeHoneychurch: Hmm, now that I look at your answer there, I'm thinking that may indeed be a better approach.

comment Can I use 'ItemStyle' in 'Grid' to specify the style of individual items?
@MikeHoneychurch: Ah, my bad. Indeed there was. I ended up using a different answer (using Item, with ItemStyle -> "Text") so I missed that.

@MikeHoneychurch: That links to this question? (And yes, I wouldn't have asked if the docs had cleared it up for me.)

Anyway, I think I've found what I was looking for; though I'm open to anything that improves on it.

I'm still open to better.

I get errors. And is that even the same thing?
