Just over a year has passed since the assassination of prime minister Olof Palme, a brutal and still unsolved handgun murder taking place in the heart of the nation's capital, Stockholm. Head of the ongoing police investigation, Hans Holmér, has just been forced to resign after cooking up increasingly incompetent and theatrical policing methods, lies and conspiracy theories. Cold war activity in the Baltic region is at peak levels. The navy regularly carry out large scale submarine hunts within Swedish territorial waters and the air force routinely scramble JA-37 Viggen interceptors in response to both Soviet and NATO counterparts scouting just outside national airspace. To fill the ranks of the armed forces, military service is mandated by universal conscription of all men aged 18 and above. Those who refuse to partake are punished by jail.

Forty years ago, the word "hacker" was little known. Its march from obscurity to newspaper headlines owes a great deal to tech journalist Steven Levy, who in 1984 defied the advice of his publisher to call his first book Hackers: Heroes of the Computer Revolution.11 Hackers were a subculture of computer enthusiasts for whom programming was a vocation and playing around with computers constituted a lifestyle. Hackers was published only three years after Tracy Kidder's The Soul of a New Machine, explored in my last column (January 2021, p. 32–37), but a lot had changed during the interval. Kidder's assumed readers had never seen a minicomputer, still less designed one. By 1984, in contrast, the computer geek was a prominent part of popular culture. Unlike Kidder, Levy had to make people reconsider what they thought they already knew. Computers were suddenly everywhere, but they remained unfamiliar enough to inspire a host of popular books to ponder the personal and social transformations triggered by the microchip. The short-lived home computer boom had brought computer programming into the living rooms and basements of millions of middle-class Americans, sparking warnings about the perils of computer addiction. A satirical guide, published the same year, warned of "micromania."15 The year before, the film Wargames suggested computer-obsessed youth might accidentally trigger nuclear war.
