July 11, 2011: Here's a real-world simulation program that was fun to write.  In simulates a bunch of pendulums of increasing lengths on a rod  and viewed from the end of the rod.  With careful selection of the lengths, some surprising patterns are formed as they swing. Check out Multiple Simple Pendulums.

July 18, 2011:  You have probably used programs asking that you choose a language at start-up.  I suspect that they all use some variation of the techniques demonstrated in this "Hello World" program.  Translations explores tools and ways to implement  foreign language support in a  Delphi program.  Give Google the credit or blame for the quality of the French, German, and Spanish translations included here. 
 

July 25, 2011:  There are occasions where it would be convenient to incorporate a text file into the executable module of a program.  Doing so eliminates the chance of the text file being accidentally deleted or modified. Today's program   StringListToResource, in Delphi Techniques, implements this ability by converting a text file to a "resource" file which may be easily embedded in the executable.   Version 2.0 of our Scan Key Codes utility program, which displays  name and scan code information as keys are pressed, was also posted today.  It  is the first test case, eliminating the previously required text file associating keyboard scan codes with  key names.
