Homebrew, everything you need

I am a Mac OS X user. I like my OS and I love how I can install/remove applications just with a drag'n drop. But some useful programs can't be find and this could be very annoying. Command-line programs like netcat or sdl-config or chocolate-doom still haven't a Mac OS X package.

The Robot and the Baby

I would like to salute John McCarthy, father of lisp recently passed away, in a more constructive way than a simple dedication.
McCarthy wrote a beautiful science-fiction story, The Robot and the Baby, talking about robot's perceptions.
I think it's quite lovely: inviting you to read it could be better than write a simple necrology.
Farewell, mr. McCarthy.

Farewell, Master

Today I read the latest sad news. Denis Ritchie, co-writer and co-ideator of UNIX and C programming language, died at 70.
Thank you for your immense contribute to computer science.

int main(int argc, char** argv){
   printf("Farewell mr. Ritchie.\n");
   printf("You made our tools.\n");
   printf("You made the True Operating System.\n");
   printf("You made us programmers.\n");
   printf("You made us hackers.\n");
   return 0;
}

Thank you
