WHAT'S NEW

August 29, 2007. Photos from 2005, 2006, and 2007 (including pictures from Italy and Japan) are now available on the Photos Page.

August 16, 2007. I've written a brief Guide to International Travel to help those new to traveling overseas. Comments are welcome.

February 10, 2007. I've enhanced the site for the Mouse programming language. Documentation and reference material is now available. Also, I've moved my Esperanto and Mouse sites to new locations.

January 15, 2007. I've made a copy of the Akademia Vortaro de Esperanto (Dictionary of the Esperanto Language Academy) available in the " Librejo" section of my Esperanto site. The word list is from the Esperanto Language Academy, and includes all "official" Esperanto words. I've created the brief English definitions from a number of sources, including Zamenhof's Universala Vortaro and Butler's Esperanto-English Dictionary. (A PDF version of the dictionary is also available.)

December 2, 2006. I've made a copy of the Dua Libro de l' Lingvo Internacia (Second Book of the International Language) by L.L. Zamenhof available on my Esperanto site. The Dua Libro, published in 1888, is an important book in the early history of the international language Esperanto. The book is located in the " Librejo" section; see the link at the top of the main page.

November 1, 2006. A few new things have been added to this site:

• The tables of Julian days on the Reference Page have been expanded to cover a period of 100 years (1960 - 2059).
• Also on the Reference Page you'll find an index to Martin Gardner's Mathematical Games column from Scientific American magazine. (See the "Mathematics" section.)
• On the Software Page, there is a new computer program marathon.f90 available to calculate a marathon training schedule. (See the "Miscellaneous" section.)

October 9, 2006. I've added some Bible passages and a list of capitals of the United States to the Reference Page.

September 25, 2006. I've added a page for my dog Scruffy, and a Fortran version of the HP-25 calculator game "Pursuit" by L.L. Simpson.

September 17, 2006.

• I've added a page for the Rosa Bonheur Memorial Park pet cemetery.
• Also, I've added a new program timer.f90 to the Software Page. This Fortran-90 module can be used as a kind of "stopwatch" for a Fortran program, and allows you to easily compute and display the total time required for a program to run.
• I've also written a small game program, Reverse (also on the Software Page). This old reverse-the-digits game is an adaptation of a game for the HP-25 calculator. See the comments at the beginning of the program for instructions.

September 10, 2006. I've moved my Web site to a new domain at: http://www.DavidGSimpson.com

Also, on the Software Page, I have updated program holidays.f90 to take into account changes in the Daylight Saving Time law over time, including the upcoming 2007 change. The program will now correctly compute the beginning and end dates of Daylight Saving Time for any year.

August 24, 2006. The News Page has finally been updated. Also, a new version 1.01d of the RPN program is now available on the Software Page. The new version adds functions HMS+ and HMS- to do time arithmetic.

May 23, 2006. Pictures of my visit with Flat Stanley are now available here!
