user programming » based programming (Expandir a busca), pair programming (Expandir a busca), r programming (Expandir a busca)
decrease fear » decrease after (Expandir a busca), decrease their (Expandir a busca), decrease cell (Expandir a busca)
fear decrease » break decrease (Expandir a busca), merr decreases (Expandir a busca), can decrease (Expandir a busca)
decrease user » increase user (Expandir a busca), decreased use (Expandir a busca), decrease after (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease fear decrease user programming ) OR ( python and pion python programming ))~.
