comment Alternative updating of a dynamic expression
This must be the saddest Q&A and accept with so low scores... :/ I find this functionality so useful, and I hardly can believe that there is no alternative (or even builtin) method to achieve this. Anyway, you got my accept!

@J.M or tri = {(* lower triangle *)}; full = tri + Transpose@tri*(1-IdentityMatrix@n). Or if the diagonal is assumed to be zero (in case of most distance functions), the 1-IdentityMatrix@n part can be omitted.

Ahh, I see, you are on v8. Then I guess you have to construct your own legend from scratch.

comment Problem with displayed coordinates in LogLinearPlot
My idea is that the PlotLegends package messes up the coordinates. Removing the legend-related options fixes it. Can you use the version 9 built in PlotLegends option instead of the (now obsolete) package?

comment Fastest way to calculate matrix of pairwise distances
I just want to point out that most of the answers (using the vectorized speedup) won't work for the more general case (e.g. Hamming distance of vectors, edit distance of strings, etc.). If one does not want to desing a specific, highly optimized method for each such case, I found that using Outer is generally the fastest way.

@acl The Transpose::nmtx error is because Solve returns {} which cannot be transposed.

comment Fastest way to calculate matrix of pairwise distances
Good question, just what I was looking for at the moment! I also wonder, how much speed can be gained if only the distance functions is reimplemented & compiled?

@acl What's wrong with this code being not minimal (apart of possible errors)?

comment Steady states and eigenvalues for a non-linear system:
Are you sure your 4th equation is ok? Shouldn't it be the derivative, Y'[t] == ... instead of Y'[t] = ...? At the moment it is recursive. Stell there is no solution for steady state (Solve returns {}).

comment Steady states and eigenvalues for a non-linear system:
Note that I is the built-in symbol for the imaginary number, which evaluates to a complex number: MatchQ[I + 1, _Real] returns False. Furthermore, as you already know it, E and even K have built-in meanings which might mess up your calculation.
