comment Bilateral Laplace Transform
@jlperla I managed to make a better implementation of bilateral Laplace transform, it can handle DE now, have a look!

comment Save a C compiled function without losing the blessing of C compiler
Actually there's no need to use LibraryFunctionLoad, the only necessary part is to save the DLL to a non-temporary directory. Then one can save & load f2 and recover the C compiled function with something like f2new = ReplacePart[f2, {-1,1} -> (* The file path of the DLL *)]. In this way the RuntimeAttributes of the compiled function will also be recovered so your answer will be fully apply to this question :D

+1. BTW it's a little surprising to me that the default Directory[] isn't included in $LibraryPath.

comment How to implement symbolic Ramanujan's summation in Mathematica?
@Anixx Yeah, the ability of Sum seems to become the new threshold. BTW the new formula using DifferenceDelta is even harder to implement… p.s. I suggest you to add these formulas to the question rather than in the comment only.

comment Speed up the auxiliary function magicSquare when $n$ is doubly-even
@ShutaoTang It's undocumented, but mentioned in a few posts here, for example this. You can have a search for more…Well, I admit I found no detailed explanation for so long. Maybe you can consider asking a separate question for this issue?

comment How to implement symbolic Ramanujan's summation in Mathematica?
@Anixx Seems to be another invalid definition: f[x_] = x; g[x_] = DifferenceDelta[f[x], x]; -NSum[ BernoulliB[Floor@n, 1]/n! Derivative[n - 1][g][0], {n, Infinity}] produces -0.5.
