comment After editing a file Mathematica 10 interprets […]^2 as […(])^2
I just want to add that entering quotes before a block of code when I use superscripts very frequently causes the formatting to screw up and for parentheses to no longer be recognized as matching. Often times, deleting the quotes and retyping them causes Mathematica to retry the formatting and that can often times fix the issue. It is very frustrating though and has existed since at least Mathematica 7.

comment RandomVariate from 2-dimensional probability distribution
Is sampling from a multi-dimensional distribution now possible in Mathematica 10?

comment Convert spectral distribution to RGB color
@halirutan From reading about it online I agree that it doesn't seem too simple, however it doesn't need to be the perfect solution. Mathematica already has some color transformation functions available, so I thought there might be some easy way to relate the matrix transformations to built-in Mathematica functions.

comment Graphics exported from Mathematica 9 are very large because even standard fonts are embedded
I know this is not a solution within Mathematica, but for those not willing/able to upgrade to Mathematica 10 yet you can use the simple Linux tool ps2pdf, which accepts PDFs as inputs as well: ps2pdf -dEPSCrop figure.pdf figure-nofonts.pdf. This will remove unnecessary embedded fonts, greatly reducing filesize (the dEPSCrop saves the original bounding box).

comment Limit as n -> ∞ for RSolve with Multivariate Recurrence Relation
@DanielLichtblau I tried, but the two Sums remain, regardless of the assumptions. The best I was able to do is get rid of the UnitStep[n-1] from the numerators when assuming n >= 1.
