Being punctual, or responsible?

Someone post about this in slashdot.org.

The issue is about leaving/creating 'dirty coding' just to fulfill deadline. Basically this is about programming ethics.

Hmm... what do you think?

Duff's Device

It looks like an invalid code, but it is valid! This code portion is known as Duff's device.

    switch (count % 8) {
       case 0:        do {  *to = *from++;
       case 7:              *to = *from++;
       case 6:              *to = *from++;
       case 5:              *to = *from++;
       case 4:              *to = *from++;
       case 3:              *to = *from++;
       case 2:              *to = *from++;
       case 1:              *to = *from++;
                      } while ((count -= 8) > 0);
   }
