Dr for Debit, Cr for Credit, but why?

There are a few different theories as to why debits are abbreviated "DR" and credits abbreviated "CR". One theory asserts that the DR and CR come from the Latin past participles of debitum and creditum which are "debere" and "credere", respectively.

Little programming: recursive function call

I have found this good example on stackowerflow.com as an illustration of the recursive function call. This is really beautiful:

A child couldn't sleep, so her mother told a story about a little frog,
  who couldn't sleep, so the frog's mother told a story about a little bear,
     who couldn't sleep, so bear's mother told a story about a little weasel
       ...who fell asleep.
     ...and the little bear fell asleep;
  ...and the little frog fell asleep;
...and the child fell asleep.

In SQL SERVER a recursive query is good to compose a tree of Bill of Materials (BOM).
