I haven't, I did not know about it. I will read it. Thanks!

Anyhow, I still believe the original essay should be improved (if I am
not completely
wrong with my understanding.)

[They use in the essay

   d=: +/ 10 1e6 ?.@$ 21        NB. data
   e=: 5 * i.40   NB. bins

which makes it work since 10 * 20 <= 5 * 40 so they will never get
outside (above) their
bins (even if they had used ? instead of ?.) But if they had used
other numbers, the
inequality could have not hold, and it would have just (sort of)
broken (in the eys of a
novice like me). There is no warning about this.]
