BTW, here is a recommended read:   
      
   David Cox; Little, John; O'Shea, Donald:   
   Ideals, varieties, and algorithms.   
   New York: Springer-Verlag, 1997   
      
   I was reading 25% of it during a train ride,   
   to kill time. Its a quite captivating read.   
      
   But I put it away, since my motto is "hands-on"   
   first. I need to get my Prototype going!
