What's New -  June, 2009

June 8, 2009:

 Here is a solitaire version of the classical Battleships game where, in addition to the ship quantities and types, you are supplied with the number of ship parts hidden in each row or column and a few preplaced ship parts.  Battleship Puzzle allows user play for a couple of sample problems which will save a bushel of eraser crumbs over pencil and paper solutions J. 

 

June 14, 2009;  Here is a "Ones" puzzle solver that finds solutions for two odometer puzzles from recent Car Talk radio programs:

1. On a six digit odometer registering from 000000 to 999999, how many times will the digit "1" appear in all of the possible numbers?

2. On the same six digit odometer, how many of the possible values contain no "1"s? 

My version also answers "How many numbers contain exactly 1 occurrence of 1?" and other variations for other odometer lengths up to 8 digits. 

June 16, 2009:  We are off for a week or so to help, or at least congratulate, a third grandchild in his transition from high school to college.  I decided to get one more program posted before the hiatus. 

 SortHTMLByDate  is a utility which will sort a  webpage with dated entries, such as this home page, into ascending date sequence.  Seems like a good idea for arranging entries for archival reading once they are moved to the What's New Archives as ndexed at the bottom of this page.   (Only are few have been converted so far as test cases.)
