Grace Hopper: The Queen of Code

The FiveThirtyEight Signals Series: 

You probably don’t know the name Grace Hopper, but you should.

As a rear admiral in the U.S. Navy, Hopper worked on the first computer, the Harvard Mark 1. And she headed the team that created the first compiler, which led to the creation of COBOL, a programming language that by the year 2000 accounted for 70 percent of all actively used code. Passing away in 1992, she left behind an inimitable legacy as a brilliant programmer and pioneering woman in male-dominated fields. 

Hopper’s story is told in “The Queen of Code,” directed by Gillian Jacobs (of “Community” fame). It’s the latest film in FiveThirtyEight’s “Signals” series.

Is the secret to a good algorithm human input?

Tim Wu in The New Yorker, posits that Netflix's secret algorithm is a human:

Perhaps what we are seeing here is better explained by the rise of a different kind of talent. It is a form of curation ... whose aim is guessing not simply what will attract viewers but what will attract fans—people who will get excited enough to spread the word. Data may help, but what may matter more is a sense of what appeals to the hearts of obsessive people, and who can deliver that. And what that suggests is that competition will remain possible for companies that aren’t Amazon or Netflix, without massive piles of data on hand. It might be enough to know just which cults to bet on.

Can the Internet be archived?

Jill Lepore for The New Yorker on a very important subject "Where is the Internet’s memory, the history of our time?":

The Web dwells in a never-ending present. It is—elementally—ethereal, ephemeral, unstable, and unreliable. Sometimes when you try to visit a Web page what you see is an error message: “Page Not Found.” This is known as “link rot,” and it’s a drag, but it’s better than the alternative. More often, you see an updated Web page; most likely the original has been overwritten. (To overwrite, in computing, means to destroy old data by storing new data in their place; overwriting is an artifact of an era when computer storage was very expensive.) Or maybe the page has been moved and something else is where it used to be. This is known as “content drift,” and it’s more pernicious than an error message, because it’s impossible to tell that what you’re seeing isn’t what you went to look for: the overwriting, erasure, or moving of the original is invisible. For the law and for the courts, link rot and content drift, which are collectively known as “reference rot,” have been disastrous. In providing evidence, legal scholars, lawyers, and judges often cite Web pages in their footnotes; they expect that evidence to remain where they found it as their proof, the way that evidence on paper—in court records and books and law journals—remains where they found it, in libraries and courthouses. But a 2013 survey of law- and policy-related publications found that, at the end of six years, nearly fifty per cent of the URLs cited in those publications no longer worked. According to a 2014 study conducted at Harvard Law School, “more than 70% of the URLs within the Harvard Law Review and other journals, and 50% of the URLs within United States Supreme Court opinions, do not link to the originally cited information.” The overwriting, drifting, and rotting of the Web is no less catastrophic for engineers, scientists, and doctors. Last month, a team of digital library researchers based at Los Alamos National Laboratory reported the results of an exacting study of three and a half million scholarly articles published in science, technology, and medical journals between 1997 and 2012: one in five links provided in the notes suffers from reference rot. It’s like trying to stand on quicksand.

The footnote, a landmark in the history of civilization, took centuries to invent and to spread. It has taken mere years nearly to destroy. A footnote used to say, “Here is how I know this and where I found it.” A footnote that’s a link says, “Here is what I used to know and where I once found it, but chances are it’s not there anymore.” It doesn’t matter whether footnotes are your stock-in-trade. Everybody’s in a pinch. Citing a Web page as the source for something you know—using a URL as evidence—is ubiquitous. Many people find themselves doing it three or four times before breakfast and five times more before lunch. What happens when your evidence vanishes by dinnertime?

Steve Wozniak Debunks One of Apple's Biggest Myths

 For its 85th anniversary, Bloomberg Businessweek chronicles the most disruptive ideas of the past 85 years. In 1976, The Apple 1 computer goes on sale for a retail price of $666.66. Steve Wozniak, who co-founded Apple with Steve Jobs and designed that product, remembers the early days.
