When she came back to her desk, half an hour later, she couldn’t log into Gmail at all. By that time, I was up and looking at eâmail, and we both quickly saw what the real problem was. In my inbox I found a message purporting to be from her, followed by a quickly proliferating stream of concerned responses from friends and acquaintances, all about the fact that she had been “mugged in Madrid.” The account had seemed sluggish earlier that morning because my wife had tried to use it at just the moment a hacker was taking it over and changing its settings—including the password, so that she couldn’t log in again.

Bernal sphere
A Bernal sphere is a type of space habitat intended as a long-term home for permanent residents, first proposed in 1929 by John Desmond Bernal. Bernal’s original proposal described a hollow spherical shell 1.6 km in diameter, with a target population of 20,000 to 30,000 people.
A modified version by Gerard Kitchen O’Neill, Island One, would have a diameter of only 500m rotating at 1.9 RPM to produce a full Earth artificial gravity at the sphere’s equator. The result would be an interior landscape that would resemble a large valley running all the way around the equator of the sphere. Island One would be capable of providing living and recreation space for a population of approximately ten thousand people, with a “Crystal Palace” habitat used for agriculture.
Sunlight was to be provided to the interior of the sphere using external mirrors to direct it in through large windows near the poles. The form of a sphere was chosen for its optimum ability to contain air pressure and its optimum mass-efficiency at providing radiation shielding.
Another version, Island Two, would be approximately 1800m in diameter, yielding an equatorial circumference of nearly six and a half kilometers. At this size, the habitat could comfortably house a population of some 140,000 people. The size was driven by economics: the habitat was to be small enough to allow for efficient transportation within the habitat and large enough to support an efficient industrial base.
