With Martin's system, each crewmember gets a cell phone that operates using a prepaid SIM card; they also get a two-week plastic pill organizer filled with 14 SIM cards where the pills should be. Each SIM card, loaded with $50 worth of airtime, is attached to a different phone number and stores all contacts, text messages and call histories associated with that number, like a removable hard drive. This makes a new SIM card effectively a new phone. Every morning, each crewmember swaps out his phone's card for the card in next day's compartment in the pill organizers. After all 14 cards are used, they start over at the first one.

Of course, it would be hugely annoying for a crewmember to have to remember the others' constantly changing numbers. But he doesn't have to, thanks to the pill organizers. Martin preprograms each day's SIM card with the phone numbers the other members have that day. As long they all swap out their cards every day, the contacts in the phones stay in sync. (They never call anyone but each other on the phones.) Crewmembers will remind each other to "take their medicine," Martin said.

The schemes that divided the day into 24 equal parts varied according to the start of the count: Italian hours began at sunset, Babylonian hours at sunrise, astronomical hours at midday and "great clock" hours (used for some large public clocks in Germany) at midnight. Eventually these and competing systems were superseded by "small clock," or French, hours, which split the day, as we currently do, into two 12-hour periods commencing at midnight.

Mike Loukides:

The small town culture (which may never have really existed) in which everyone knew everything about everyone disappeared as we moved into suburbs, where nobody knew anything about anyone. And that's really where our notions of "privacy" arose. The local pharmacies started disappearing, to be replaced by big chains like CVS and Walgreens. As Douden's and Jolly's disappeared from local culture, so did the local pharmacist who knew and remembered who you were and what you bought, and who was able to put two and two together without the help of a Hadoop cluster.

Laurie Garrett:

Rather than trying to censor research because its inevitable release might be harmful, we ought to be having a frank, open discussion about its implications.

Thomas Rid:

Cybersecurity has a broader meaning in non-democracies: For them, the worst-case scenario is not collapsing power plants, but collapsing political power. Russia and China are ahead of the United States, but mostly in defining cybersecurity as the fight against subversive behavior. This is the true cyberwar they are fighting.
