The 24 People Who Decide Acceptable Speech On The Internet

Free speech on the internet decided by 24 key people: "Google, Twitter, Facebook and the new global battle over the future of free speech".

From the article:
The deciders, of course, have blind spots of their own. Their hate-speech policies tend to reflect a bias toward the civility norms of U.S. workplaces; they identify speech that might get you fired if you said them at your job, but which would be legal if shouted at a rally, and try to banish that expression from the entire Internet. 

But given their tremendous size and importance as platforms for free speech, companies like Facebook, Google, Yahoo, and Twitter shouldn’t try to be guardians of what Waldron calls a “well-ordered society”; instead, they should consider themselves the modern version of Oliver Wendell Holmes’s fractious marketplace of ideas—democratic spaces where all values, including civility norms, are always open for debate.
In this respect, Twitter seems to be doing better than Google and Facebook.  The article also notes:
As corporate rather than government actors, the Deciders aren’t formally bound by the First Amendment. But to protect the best qualities of the Internet, they need to summon the First Amendment principle that the only speech that can be banned is that which threatens to provoke imminent violence, an ideal articulated by Justice Louis Brandeis in 1927. It’s time, in other words, for some American free-speech imperialism if the Web is to remain open and free in twenty-first century.

Siri Remembers For 2 Years

Apple's Siri remembers user queries for up to 2 years:
Whenever you speak into Apple’s voice activated personal digital assistant, it ships it off to Apple’s data farm for analysis. Apple generates a random numbers to represent the user and it associates the voice files with that number. This number — not your Apple user ID or email address — represents you as far as Siri’s back-end voice analysis system is concerned.

Once the voice recording is six months old, Apple “disassociates” your user number from the clip, deleting the number from the voice file. But it keeps these disassociated files for up to 18 more months for testing and product improvement purposes.

“Apple may keep anonymized Siri data for up to two years,” Muller says “If a user turns Siri off, both identifiers are deleted immediately along with any associated data.”

I wouldn't necessarily call them "insane lengths", but it sounds like they made a major effort.  I look forward to seeing the film! (Via Rand Simberg.)

Game Theory and Jane Austen

NYT: "Game Theory: Jane Austen Had It First"
Take the scene in “Pride and Prejudice” where Lady Catherine de Bourgh demands that Elizabeth Bennet promise not to marry Mr. Darcy. Elizabeth refuses to promise, and Lady Catherine repeats this to Mr. Darcy as an example of her insolence — not realizing that she is helping Elizabeth indirectly signal to Mr. Darcy that she is still interested.

How Does China Censor the Internet?

Econimist: "How does China censor the internet?"
In short, China is having it both ways: it is allowing its citizens to benefit from the social and commercial aspects of the internet, while placing strict limits on its use for political activism.

The Dark Side of the Digital Revolution

Schmidt and Cohen:: "The Dark Side of the Digital Revolution"
While technology has great potential to bring about change, there is a dark side to the digital revolution that is too often ignored. There is a turbulent transition ahead for autocratic regimes as more of their citizens come online, but technology doesn't just help the good guys pushing for democratic reform -- it can also provide powerful new tools for dictators to suppress dissent.

Moore’s Law and the Origin of Life

"Moore's Law and the Origin of Life"

The basic premise is controversial: "As life has evolved, its complexity has increased exponentially, just like Moore's law. Now geneticists have extrapolated this trend backwards and found that by this measure, life is older than the Earth itself." (Personally, I'm skeptical, but I thought it was interesting enough to post.)

Feds Unhappy About iMessage Encryption

"Apple's iMessage encryption trips up feds' surveillance":
An internal Drug Enforcement Administration document seen by CNET discusses a February 2013 criminal investigation and warns that because of the use of encryption, "it is impossible to intercept iMessages between two Apple devices" even with a court order approved by a federal judge.

The DEA's warning, marked "law enforcement sensitive," is the most detailed example to date of the technological obstacles -- FBI director Robert Mueller has called it the "Going Dark" problem -- that police face when attempting to conduct court-authorized surveillance on non-traditional forms of communication.

History of Rome Podcasts

I've really been enjoying these "History of Rome" podcasts.  My favorite line from episode 136:
Diocletian had done his best to establish a system that would end once and for all the persistent civil wars that had wracked the Empire of the 3rd century. And instead, he inadvertently had drawn up what amounted to a giant civil war tournament bracket. In the championship game, Constantine finally had emerged victorious.
