[edit] NeXT OS
On this day in 1996, Apple acquired NeXT Software Inc for $400M. The acquisition brought Steve Jobs back to Apple, and NeXT Step operating system was used as the foundation of OS X.
The NeXT OS was written in Objective-C, an object oriented language with roots in C and smalltalk. Objective C features dynamic typing, binding, and loading. The hello world program in Objective C can be written like this:
#import <stdio.h>
int main( int argc, const char *argv[] ) {
printf( "hello world\n" );
return 0;
}
[edit] David Bohm
And, today in 1917 was the birthday of David Bohm, American quantum physicist. After helping on the Manhattan Project, he was later branded a communist and moved to Brazil. Besides, physics, he had philosophical theories related to the human brain operating using wave interference, like a hologram.
Bohm Quote: The ability to perceive or think differently is more important than the knowledge gained.
