Spring is coming!
We have had several days of temperatures in the mid 50's here on the
mountain last week, after a couple of single digit nights two weeks ago.
So maybe winter will come to an end after all.
We passed 15,000 home page visitors today!
Soap-box time: I've been puzzled by the
Microsoft bashing in the technical press since the anti-trust trial
started. In the past year I've unsubscribed from most of my email
technology newsletters when an issue arrived that was too biased to tolerate.
I recently ran across this Op-Ed piece, Drop
the AntiTrust Suit Against Microsoft, that's
a little extreme, but still makes some sense to me. If
you're interested, read it and decide for yourself.
I had a birthday last week and received a Mensa puzzle book
from a daughter. So -- expect a couple of problem solving
programs based on those puzzles this month. Also a cool card trick
program plus I'm going to figure how to download and interpret the data
from that GPS navigation device I received for Christmas. That
should keep me occupied for a few days.
In the meantime, here are the
"What's New" details for the last six weeks:
January 30, 2002: Here's puzzle/game I call Traffic Jam. It's modeled after the original plastic version, RushHour, by Binary Arts. The objective is to free the target car by moving those that are blocking it's way. Vehicles can move only in the direction of their long axis. A simple case with the objective of moving the red car to the exit looks like this: February 10, 2002: I've been playing with Doodler 2 for several days. (Doodler 1 was posted about a month ago.) Printing and rotating drawings is working fine, but kaleidoscope drawing is driving me crazy! I decided to take a break and work on a few simpler programs. One is an arithmetic drill program modeled after Arithmattack, a Javascript program posted at the Argonne National Laboratory website. My beta tester (aka wife) complained about my use of * and / for multiply and divide. That led to today's posting - a FontViewer written to find those elusive × and ÷ symbols. It could also be useful if you need the ™, ©, ®, or ± symbols which are buried in most fonts. I used the OnDrawCell event exit to display fonts in a Stringrid, so decided to post it over in Delphi-Techniques as an example of this Stringgrid drawing technique.
February 21: 2002: From an old ACM Programming Contest, here's a problem I call Slimps, Slumps and Slurpies. These are strings of characters following certain formation rules. The definitions are recursive, meaning that the rules may include the terms being defined. The idea is to write a program that recognizes each type. Kind of a compiler for the "Slurp" language
Not that it matters, but I haven't been able to find a definition of "championship golf course" to verify that the premise of the question is true.
"Nothing can stop the man with the right mental attitude from
achieving his goal; nothing on earth can help the man with the wrong mental
attitude." -- Thomas Jefferson
Or more concisely:
"Whether you think you can or think you can't, you're
right." - Henry Ford
