As of October, 2016, Embarcadero is offering a free release of Delphi (Delphi 10.1 Berlin Starter Edition ).     There are a few restrictions, but it is a welcome step toward making more programmers aware of the joys of Delphi.  They do say "Offer may be withdrawn at any time", so don't delay if you want to check it out.  Please use the feedback link to let me know if the link stops working.

Mensa Daily Puzzlers

For over 15 years Mensa Page-A-Day calendars have provided several puzzles a year for my programming pleasure.  Coding "solvers" is most fun, but many programs also allow user solving, convenient for "fill in the blanks" type.  Below are Amazon  links to the two most recent years.

Below is and index of available math topics - mostly relating to problems solved while writing programs.  

There are a number of entries in the Programs section which should probably be moved to or at least indexed from  Math Topics.   Permutations, Big Integer Arithmetic, Pi calculation,  Primes, Genaille's Rods, etc.  come to mind.

One of these days....
