Talking about OSX Hello World:

Source and Universal binary at http://abuse.mooli.org.uk/HelloWorld/

On an Intel Mac:

abuse at paratha:~$ ps -lwwp 10239
   UID   PID  PPID CPU PRI NI      VSZ    RSS WCHAN  STAT  TT

0:00.46 /Users/abuse/Desktop/Hello World.app/Contents/MacOS/Hello  
World -psn_0_36306945

I'm not sure which to balk at more: the 23MB resident, or the 235MB  
virtual.

(OK, it's a PyObjC application rather than native ObjC, but I can't  
stand the latter and the size didn't actually drop noticably when I  
last wrote a direct ObjC application a couple of years ago.)

1993, I'd just got my Amiga 4000 which had a whole *six* megabytes of  
memory.
