The ten-year-old in question is Jessica, Gordon’s daughter, who dropped into the office last week to give us a hand testing some Raspberry Pis that customers had sent back to the manufacturers as “faulty”. Whenever this happens, the Pis are passed on to us or to the Sony factory in Wales where the Pis are built, and we test them to find out what’s going on and to ensure that there isn’t a bug in manufacturing. At the moment, we see returns in the order of about 0.02% of all units (the ones Jessica is working on are on the right of her desk)
