Tech Life looks at satellite navigation and the increase in cases of signal interference. How could this affect shipping and aviation safety, and what can be done about it ?
Also in this edition, what digital material of cultural significance should be stored for the future ? A volunteer project is improving Wikipedia's photographs. And we find out about efforts to harness the power of the moon on the Faroe Islands.
