* last ish.

You're supposed to concatenate all the input numbers, to create a message that has hundreds or thousands of digits; then RSA-encrypt that number.

The discussions always split between the people who just want to get on with the conversation and the people who can't bring themselves to do that because they consider it unforgivably rude. The second group never seem to take the hint that the first interruption is an imposition in itself.

J comes with a Qt IDE, which has a function "dissect" that displays a graphical parse tree of an expression.

load 'debug/dissect'

dissect '(+/ % #) ? 10 $ 100'

It was an internal Wiki page at Google written when I was an SRE. After I wrote the original page, someone put up an internal shortlink at "go/nohello". After I left Google, someone took the Wiki page content and [illegally, since it was Google confidential, simply from being on the internal Wiki], and put it up on the net at "nohello.com".

  The following mapping from letters to digits is given:

  E | J N Q | R W X | D S Y | F T | A M | C I V | B K U | L O P | G H Z
  e | j n q | r w x | d s y | f t | a m | c i v | b k u | l o p | g h z
  0 |   1   |   2   |   3   |  4  |  5  |   6   |   7   |   8  
 |9
  

  We want to use this mapping for encoding telephone numbers by words, so
  that it becomes easier to remember the numbers.
