It takes 10 years to develop expertise

From Peter Norvig’s “Teach Yourself Programming in Ten Years” (2001):

Researchers ([John R. Hayes, Complete Problem Solver (Lawrence Erlbaum) 1989.], [Benjamin Bloom (ed.), Developing Talent in Young People (Ballantine) 1985.]) have shown it takes about ten years to develop expertise in any of a wide variety of areas, including chess playing, music composition, painting, piano playing, swimming, tennis, and research in neuropsychology and topology. There appear to be no real shortcuts: even Mozart, who was a musical prodigy at age 4, took 13 more years before he began to produce world-class music. In another genre, the Beatles seemed to burst onto the scene with a string of #1 hits and an appearance on the Ed Sullivan show in 1964. But they had been playing small clubs in Liverpool and Hamburg since 1957, and while they had mass appeal early on, their first great critical success, Sgt. Peppers, was released in 1967. Samuel Johnson thought it took longer than ten years: “Excellence in any department can be attained only by the labor of a lifetime; it is not to be purchased at a lesser price.” And Chaucer complained “the lyf so short, the craft so long to lerne.”

A prison completely run by the inmates

From Mica Rosenberg’s “Guatemala forces end 10-year prisoner rule at jail” (The Washington Post: 25 September 2006):

Guatemalan security forces took over a jail run for over 10 years by inmates who built their own town on prison grounds complete with restaurants, churches and hard-drug laboratories.

Seven prisoners died when 3,000 police and soldiers firing automatic weapons stormed the Pavon prison just after dawn on Monday.

Corrupt guards would only patrol the prison’s perimeter and run the administration section while an “order committee” of hardened inmates controlled the rest. They smuggled in food, drink and luxury goods.

“The people who live here live better than all of us on the outside. They’ve even got pubs,” said soldier Tomas Hernandez, 25.

Pet dogs, including a whining puppy, roamed the deserted prison grounds after the raid. One inmate kept a spider monkey captive, national prison officials said.

But with army helicopters clattering overhead, police backed up by armored cars transferred Pavon’s 1,600 inhabitants to another prison, ending their lives of ease.

The inmates who died were killed in a shootout at the two-story wooden chalet of a convicted Colombian drug trafficker knows as “El Loco,” or “The Madman.”

Blood was splattered on the house’s walls and floor. The Colombian had a widescreen television and high-speed Internet.

Pavon was one of the worst prisons in Guatemala’s penitentiary system, where common criminals, rival “mara” street gangs and drug traffickers often battle for control.

Police had not been into Pavon, on the edge of the town of Fraijanes, since 1996.

It was originally built for 800 inmates as a farm prison where prisoners could grow their own food. But the prison population grew over time and inmates began to construct their own homes on the grounds.

Guards let prisoners bring in whatever they wanted and inmates set up laboratories to produce cocaine, crack and liquor inside Pavon. …

Inmates extorted and kidnapped victims on the outside by giving orders via cell phone. …

They also killed Luis Alfonso Zepeda, a convicted murderer who headed the “order committee.”

Zepeda earned around $25,000 a month from extortion, renting out prison grounds to other inmates and drug trafficking, police said.

His son Samuel lived illegally inside the prison to help run the crime empire, even though he was never sent there by a court. …

Inmates ran at least two churches, one Catholic and the other Evangelical, and restaurants serving typical fare like stews and tortillas.

Stores controlled by the prisoners sold soft drinks and potato chips brought in from the outside.
