Tetris clone coded using GWT and the SmartGWT API
- Tetris is an incredibly addictive game. It was created in 1984 by Alexey Pajitnov, while I was still a kid and the Berlin
wall still divided Germany into two regions. Its origin is marred with cold war paranoia. If you want the details (and why wouldn't you),
you must watch the documentary Tetris - From Russia with Love.
- I first played the game around 1989 or 1990 in local arcades, along with my other favorite titles such as
Defender and Pac-Man. I've thought of creating my own games ever since, but computers were hard to
come by in the mid 80s. I had to wait a long time until I actually coded my own version.
It's not a hard game to program, but it has its challenges. Enjoy...

Java Applet Histogram Calculator
- Variability is part of nature. Trying to understand this variability
is part of a Mathematician's job. The easiest way to study variability
and predictability in a data set is by drawing curves and plotting
data. A histogram is a great tool to assess the normality of
"random looking" data sets.
- This is my pointless contribution to the field of Statistics:
a Histogram Calculator.

And now...Datevid Letterman's stupid date tricks...
- In a current project (Today is June 9, 2004), a colleague
of mine had to figure out which date a specific day was in a
particular month.
For example: What date does the second sunday of May of 2004
fall under? That's mother's day in North America...
