Donne di ieri e... di oggi (2)

Da Repubblica.it: "Angela, 24 anni, ha vinto il concorso russo di bellezza online "Miss Virtual Yakutia". Ma la miss si è dimostrata "troppo" virtuale: si chiama Oleg ed è un uomo. La truffa è stata svelata dallo stesso Oleg, che ha pubblicato sul sito tutte le fasi del trucco"

So già di sforare nel più bieco maschilismo, ma quando si dice che non ci sono più le donne di una volta...

Donne di ieri e... di oggi (1)

Ecco come doveva apparire Thea, una donna del Paleolitico vissuta in Sicilia 14 mila anni fa e recentemente ricostruita. Direi che qualche passo avanti è stato fatto.

Writing a chess engine 1: to choose a programming language

[Update: you can find a new version of this on mizarchessengine.com ]

Some people mail me to ask how to write a chess engine. So i thought to write some columns to help them. From today i'm going to write a short description about writing a simple chess engine. First of all: English isn't my first language, so if you find mistakes, please sorry and mail me: i'll fix them.

In this column we'll talking about which is the best programming language to write a chess engine. The answer is simple: "The one you know best!". There are engines written in C++, C, Java, Delphi/Pascal, Visual Basic, Assembly...

Mizar is written in C.

From the web you can download a lot of source code and a lot of free compilers or IDE.

About C/C++ i suggest:

Code::Block it is a good IDE and works with a lot of free compiler
Open Watcom is the free release of the old good compiler (work with Code Block)
Digital Mars is a free compiler (work with Code Block)
MinGW it is a "GCC for Windows"
Visual C++ Express 2005 is fast, is free, i think it is the best
Update: now you can download Visual Studio 2008 Express

After that i suggest to use program like CVS to implement revision control.
