Talvez deva tentar algumas variações de ortografia:
line programming » linear programming (Expandir a busca), cone programming (Expandir a busca), linear programmin (Expandir a busca)
coder testing » model testing (Expandir a busca), mode testing (Expandir a busca), cancer testing (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
testing line » testing linear (Expandir a busca), testing blind (Expandir a busca), testing long (Expandir a busca)
coder coder » coder decoder (Expandir a busca), code code (Expandir a busca), decoder codec (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder coder testing line programming ) OR ( AND python python python programming ))~.
