comment Why does having many Print statements slow down my code?
Okay; does PrintTemporary[] also incur a speed penalty when used?

comment Where is f2mma.zip, Fortran to Mathematica converter?
Before anyone else tries it out: the Wayback Machine was not able to save a copy of the sought *.zip file. :(

comment How to further accelerate arithmetic with Fermat Pseudoprime and Fibonacci number
One more thing: I'd use PowerMod[] instead of using Divisible[] on a big pseudoprime for testing Fermat's little theorem.

How about replacing all instances of Print[] with Sow[] and enclose the entire beast in Reap[]? You can then study the list thus produced at leisure.

comment Series of square root of exponential
Actually, with PowerExpand[], you don't need the assumptions; using it assumes that the unknown quantities being rooted are supposed to be positive.

comment Series of square root of exponential
I see. What happens after applying PowerExpand[]?

comment Series of square root of exponential
Have you tried expanding the function first and then taking the square root of the resulting series?

comment Hill function (equation) vs a gene
Actually, you only missed one from your list of reserved capital letters: O[]. ;)

comment Sow only if different than zero
With respect to $3j$, if need be, you could try implementing the method here.

comment Gaussian Elimination with full pivoting
Just in case, you might want to look at the version by Golub and Van Loan.

comment Function for a series of joined slopes
For the case of the accepted answer, I think turning the indefinite integral into a definite one (thus, enforcing a boundary condition) should work; if memory serves, the indefinite integration happens to pick the particular integral that is zero at the left endpoint.
