Talvez deva tentar algumas variações de ortografia:
cracker program » tracker program (Expandir a busca), crawler programa (Expandir a busca), teacher program (Expandir a busca)
computation in » computation and (Expandir a busca), computation of (Expandir a busca), imputation in (Expandir a busca)
using locking » using stacking (Expandir a busca), using long (Expandir a busca), using ranking (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
in cracker » in crackers (Expandir a busca), in cracked (Expandir a busca), in crack (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( AND computation in cracker program ) OR ( using locking python python programming ))*.
