In other words, it can experiment. “We’re kind of flying the plane while we’re building it,” Ventilla said. This is a tried and true cliché of Silicon Valley product development. The old way, think Microsoft, was to tinker for years on complicated software and then ship it at once. The new way, think Facebook, is to iterate and then ship frequently.

The difference is that AltSchool is experimenting with the lives of children, not a better way of tagging beer-bust photos. The reason the plane-flying analogy amuses is that no one in their right mind would tinker with an airborne plane. Yet AltSchool asks parents to pay for the privilege of supplying their children as guinea pigs.

Some of what it is doing is fascinating. AltSchool has raised $133 million, and it has developed unique technology that borrows from current tech-industry memes. A student “playlist” shows all the topics and tasks accomplished. This not only allows a teacher to focus on unknown areas but also, cleverly, avoids wasting a child’s time rehashing completed material. A “parent portal” provides a stream like Facebook’s News Feed to keep parents up to speed on their child’s progress.

I’m intrigued by AltSchool, and my biggest gripe, which I shared with Ventilla, is that he’s not applying his energy, smarts, and vast amount of available capital to improve public schools, especially in San Francisco. He hopes the company’s “platform” eventually will be available to public schools.

Rebecca Mead’s meticulously reported feature in the current issue of The New Yorker, “Learn Different,” discusses this and many other pros and cons of AltSchool’s approach. I highly recommend it if you’re half as intrigued as I am.

BITS AND BYTES

Ransomware targets Apple users. A malicious kind of software program that holds a computer's data for ransom has for the first time struck Macintosh computers, according to cybersecurity firm Palo Alto Networks.

Apple vs. FBI developments. Federal agencies' conflicting views on encryption technology have left the Obama administration floundering without a clear stance on the matter.

Fortune's Geoffrey Smith and Roger Parloff take you inside the Volkswagen emissions scandal.

In late 2008 a publication called Green Car Journal compared the five finalists of its annual Green Car of the Year award. “Fulfilling this growing desire for vehicles with better fuel economy and overall environmental performance is no easy thing,” it noted. “Rising to the top is the 2009 Volkswagen Jetta TDI.” The car was the winner because its “groundbreaking clean diesel” engine managed to meet America’s “stringent tailpipe emissions standards” while also delivering “admirable fuel efficiency,” “satisfying performance,” and “a very reasonable” price.

That award was recently rescinded. The Jetta—like at least 14 other so-called Clean Diesel models sold by Volkswagen Group under its VW, Audi, and Porsche marques from 2008 to 2015—was actually the automotive equivalent of Piltdown Man. It was a hoax.

About 580,000 VWs in the U.S.—and almost 10.5 million more worldwide—weren’t really “green” at all … Read the rest on Fortune.com.
