Mark Wielaard: New GPG key.
Finally created a new GPG key using gnupg. The old one was a DSA/1024 bits one and 8 years old. The new one is a RSA/2048 bits one. I will use the new one in the future to sign any release tarballs I might create. pub 2048R/57816A6A 2011-01-29 Key f...

Real multi-threading in JavaFX
I developed my first implementation of the Reversi game on BASIC 20 years ago. Since then, I ported it on each programming language I studied: Turbo Pascal with graphics library and Turbo Vision, C with the Windows API, C++ with the ClanLib, Java AWT applet, and Swing application with Java2D. Now I am ready to publish yet another implementation, on JavaFX Script.
javafx({
name: "Reversy",
width: 400,
height: 450,
archive: "https://malenkov.dev.java.net/20100813/Reversy.jar"
});
This game allows to compete with one of the algorithms as well as to see how these algorithms compete with each other. The Sergey algorithm is based on the Minimax algorithm with a simple table of game piece weights where the calculation depth is 6. The Pavel algorithm is developed by my colleague, and I have got it from the official JavaFX site. But I had to add the following constructor:
public Board(GameBoard board) {
this();
Object dark = board.getFriend();
Object light = board.getEnemy();
int pos = 11;
for (int y = 0; y < 8; y++, pos += 2) {
for (int x = 0; x < 8; x++, pos++) {
Object piece = board.getPiece(x, y);
this.data[pos] = (piece == dark)
? PIECE_DARK
: (piece == light)
? PIECE_LIGHT
: PIECE_EMPTY;
}
}
this.movePiece = PIECE_DARK;
prepareMoves();
}
When I increased the calculation depth, I disc...
