comment Problem inserting data into a mysql table with column names having a space
"\"Col 1\"" works for creating column - but is problematic while inserting using SQLInsert. Tried [Col 1] - it does not help either

Thanks you were right. On removing the assumption L>0 from the Simplify[] and the results match!

I would like to add the contours for the mesh (black) lines here

comment Plotting ContourLabels on ContourPlot3D
@Artes : Thanks for pointing it out - the solution was to overlay the different plots. Whereas in this case of plotting contourLabels, one cannot user overlay (at least directly), since the position of the contourlines are not known apriori. Maybe one can get the contours from the expression (mathematica.stackexchange.com/questions/20281/…) and then evaluate the value of the function there and put a value there. But I was interested in knowing if there is a way to get it done using contourLabels

to make sure it performs utmost iters no of evals, need to replace >= with = (can't edit it - min num of chars required for edits to be accepted)

comment Shaving the last 50 ms off NMinimize
@OleksandrR. Is there an equivalent for FindMinimum. I tried Trace[FindMinimum[x Cos[x], {x, 2}], TraceInternal -> True] and I see something like OptimizationInternalModifiedCholesky$4575`.

comment Reference request for neural network programming in Mathematica
Is the NeuralNetworks package still under development? The example here (library.wolfram.com/examples/exchangerate) and the official documentation (media.wolfram.com/documents/NeuralNetworksDocumentation.pdf) seem to use <<LinearAlgebraMatrixManipulation which is obsolete!
