New "Proof" of P=NP

Credit goes to Jeff Shallit again, for having found the most stupid "mathematical paper" of all times. It can be found here. After proving that the real numbers form a countable [sic] set, the author "establishes" the proof of a long-standing open problem.

It is a recommended read for those who suffer from insomnia and other maladies. As Shallit remarks, it is "a veritable garden of crankiness".

Oh yes, let us not forget the "proof" of Fermat's last theorem.

"Proof" of Fermat's Last Theorem

Via Recursivity, I became aware of a certain "journal" titled Journal of Mathematical and Computational Science, which publishes articles like this:
A simple proof of the [sic] Fermat's last conjecture and the connection with the Goldbach conjecture, by Ikorong Anouk Gilbert Nemron.
I offer it to my readers as a prime example of a pitiful paper, of no substance at all, which finds its place in a "journal", after, supposedly, having been peer-reviewed by one or more referees chosen by the editorial board. The people at the editorial board should be completely ashamed of letting junk, like the paper above, being published.

But, as a colleague of mine remarked, anything, absolutely anything can be published nowadays, somewhere. The problem with certain journals is that there is zero quality control. I urge my readers to click on the link above and have a laugh. There is material for laugh for everyone.You don't need to know mathematics (neither does the author) to have a laugh.

What measure theory is about

It's about counting, but when things get too large.
Put otherwise, it's about addition of positive numbers, but when these numbers are far too many.

The principle of dynamic programming

max_{x,y} [f(x) + g(x,y)] = max_x [f(x) + max_y g(x,y)]

The bottom line
