So construction on the second Death Star is going pretty well here around the Forest Moon of Endor.
They've got some fancy shield protecting the Death Star during construction. It's projected from the surface of the moon, and there's a complicated set of codes to disable it if you need to land near the shield generator or on the Death Star itself.
Actually, they've just rolled the codes over to a new set. I managed to successfully make the point that old codes should be disabled, to prevent them verifying in the system. The last thing we want is to have older codes that still check out and allow the shield to be disabled. Tiaan Jerjerrod promised to take care of it "soon", pleading how busy he was. After some insistence on my part, I got him to promise that he'd take care of it today, and the old codes would stop working immediately after the meeting.
He even said I could take a copy of the old codes to my Bothan Cryptographers meeting next week, to show off examples of the fine level of Imperial cryptography.
