comment Composition à la Mondrian
@belisarius - re: Titian take a look at this link from the Frick collection in NY. You can zoom around the painting and see lots of this kind of thing.

comment What kind of Mathematica license do i need to create cdf documents for my students and put them on my (academic) page at the university?
Checked with Bradley. He replied, "...totaly fine to post my contact information..."

@Mr.Wizard - I contacted Brad directly for permission after seeing your concern and will certainly take his guidance. Note, one can, with little effort, obtain this contact information from public sources.

comment Computing the Hurst exponent or fractal dimension of fractional Brownian motion
I think he uses R as Rescaled Range (The rescaled range is a statistical measure of the variability of a time series...) Rescaled Range. Also see: Hust Exponent. I think I've got a notebook on this I'll try to dig it out of my archive.

comment Plotting Semi-hollow spheres
This really had me puzzled. So many simple ways that Mathematica ought to let one do this but doesn't ;-( Great solution with broad application. +1

comment Mathematica policy for correctness of results
Anyone developing serious software that may risk "Millions" should probably design an appropriate level of user acceptance testing prior to rolling it into production. Then, the responsibility properly falls on the user.

comment Will Version 9 functions all work in Version 10?
@Mr.Wizard - Yes that does sound right and oddly comforting to recall some of the details and challenges of those changes. Thinking about it less specifically just got me a bit worried.

@Öskå - Happy to see this moved to Meta if everyone thinks it makes more sense there.

comment Will Version 9 functions all work in Version 10?
@Szabolcs - Thoughtful and noted. Thanks, I just still remember a version change where all sorts of functions no longer worked. A simple statement that MMA 10 extends MMA 9 and doesn't upset any of it from Wolfram would do a lot to ease my mind.

comment Arranging and combining multiple plots and graphics
Unfortunately, Mathematica (for all its wonder) does not have a simple or direct way that I know of to do what you want to do. I may have missed something (or a lot), but I'd love to have a way of specifying absolute size of each cell in a grid object of some kind (e.g., GraphicsGrid[], Grid[], ???) and then have the ability to put whatever I want into them specifying the absolute size of each element as well. Having absolute control of alignment in each cell as well as spacing would help too. This sounds like a simple idea, but it seems hard to do. I'd love to see a solution.

comment Arranging and combining multiple plots and graphics
re: your Update 1: Try making the bottom scale of the plot a separate element and place it in its own row.
