Et harum scientiarum porta et clavis est Mathematica

"Mathematics is the door and key to the sciences" - Roger Bacon (~1214-1292)

$$ \sum_{n=1}^\infty\frac{1}{n^z} = \prod_{p \text{ prime}} \frac{1}{1-p^{-z}} $$

comment What are the best tips in Michael Trott's beer/whiskey Wolfram Blog post?
I find Trott's Mathematica Guide Books interessting, but such posts as this beer/whiskey one is a waste of time. Yes, he is an expert Mathematica programmer and he can demonstrate his proficiency but I don't favour such rubbish as that post and find it very confusing.

comment How to find the period of an arbitrary mathematical function?
@Rojo In ver. 10 there is FunctionPeriod however I couldn't find its advantages over Periodic'PeriodicFunctionPeriod, at least such that I'd like to mention them. In all the above examples where the latter fails either the former does.

comment DSolve not finding solution I expected
@StephenLuttrell This is a useful observation however the problem that DSolve yields generic solutions remains.

comment How to count the integer grid numbers defined by inequalities?
Closely related: How to find lattice points on a line segment?. If there are many solutions Reduce can't be efficient however a neat approach with FrobeniusSolve can yield all interesting solutions as in one of the answers in the link. For benchmarks see this answer Finding the number of solutions to a diophantine equation.
