This may be OT...: 

-- not only does it "not" explicitly mention Gnu/Linux, or FLOSS as such, but it quotes a roboticist, (David Bruemmer), 

("who runs the [Idaho National Laboratory (INL)] Robotic Intelligence Kernel laboratory")

saying something that, seems like he is speaking highly of Windows. 

Some of you might find that puzzling, or even disturbing... 

Arizona in the news: 

It even mentions hardware 

("researchers used a robot equipped with chemical sensors to search a tunnel near Arizona's border") 

and "Homeland Security officials" (think: Janet Napolitano)
