Talvez deva tentar algumas variações de ortografia:
refactoring programs » mentoring programs (Expandir a busca), mentoring program (Expandir a busca), teaching programs (Expandir a busca)
java refactoring » and refactoring (Expandir a busca), live refactoring (Expandir a busca), soa refactoring (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
coder coder » coder decoder (Expandir a busca), code code (Expandir a busca), decoder codec (Expandir a busca)
coder java » codes java (Expandir a busca), xcode java (Expandir a busca)
in python » _ python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder coder java refactoring programs ) OR ( in python python python programming ))~.
