Take 5-10 min survey on animals, technology, and nature for a $20 Barnes&Noble gift certificate
Hello, I am a psychology student at University of Chicago conducting a survey on animals, technology, and nature. It takes only 5-10 minutes to complete and every 20th participant will be emailed a $20 gift certificate to Barnes & Noble. This should be an interesting opportunity to learn things about yourself as well. To participate, click on the link below. You may only take the survey once and will be ineligible if you do so more than once.

question about Tkinter delete
Hi all I don't understand why I get this error. I'm trying to delete the existing points, then redraw them after this bit of code to 'animate' my simulation. def update(self, point1, point2): # Deletes existing points if self.point1: self.w.delete(point1) self.master.update_idletasks() if self.point2: self.w.delete(point2) self.master.update_idletasks() #draw new point # . . . The error message that I get is: . . . in update self.w.delete(point1) File "C:\PYTHON26\LIB\LIB-TK\Tkinter.py", line 2181, in delete self.tk.call((self._w, 'delete') + args) TclError: invalid command name ".44593760"-- http://mail.python.org/mailman/listinfo/python-list

Might hold true for some rants, but most of it's tl;dr drivel. For instance, his critique of Lisp's homoiconicity is completely off-target. > I come from a different world than IT, and I thought initially the IT > world would be filled with intelligent, free thinking, and open minded > people...

Dijkstra and his followers get dismissed as ivory tower intellectuals. FUT warning. -- You only have power over people so long as you donât take everything away from them.
