[chernobyl] The Age of Forever Crises … This analysis of the nuclear disaster at Chernobyl seems somehow relevant during Covid-19. ‘Chernobyl, in this sense, is a crisis that has never stopped unfolding, or as Brown puts it, it is a calamity “with no perceptible end.” It is just as much an environmental disaster as a crisis of information; Cold War politics prevented the free exchange of scientific knowledge, making a bad situation infinitely worse. Brown explains how, in 1986, Russian scientists asked UN officials for “precise information” about how the “Life Span Study” of Japanese survivors of the nuclear bomb was carried out; they were instead presented with data about a chemical explosion in Italy.’

[tech] Reboot Your Dreamliner Every 248 Days To Avoid Integer Overflow … Why Boeing 787s need to be rebooted regularly to avoid integer overflows. ‘Basically it says that all Boeing 787 Dreamliners have to be switched off every 248 days. If they are not reset then the generator control units GCUs will go into failsafe mode and the plane will lose all electrical power. Why exactly? To quote the FAA directive: This condition is caused by a software counter internal to the GCUs that will overflow after 248 days of continuous power. We are issuing this AD to prevent loss of all AC electrical power, which could result in loss of control of the airplane.’

This is the stuff of tragedy that can never be completely explained.’
