The art of the password

Good overview of the state of password creation (and cracking) by William Poundstone.

Though I never bother with such websites, I hadn't realized the following:

Have you ever wasted a few moments with a sketchy website that promises to reveal your Klingon name (wizard name, ghetto name, porn star name, etc.)? Some of these sites are fronts for password-harvesting operations. They’ll ask you for some personal data—mixed in with Trekkie trivia —and prompt you to make up a password. Scammers know that the password you supply is likely to be similar or identical to ones you use elsewhere. They may sell collected passwords on the black market for about $20 each.

A password is like the key to your home. There are weak locks and strong locks, but neither does any good when a pickpocket swipes your key. Security is always about the weakest link.
 

Poundstone's advice on picking a secure password:

The best way to use the pass-phrase idea is to turn the conventional advice on its head. Instead of thinking of a phrase and converting it to a password (that won’t be all that random), get a truly random password and convert it to an easy‑to-remember phrase.

...

A password, a pass-phrase, a mnemonic—what’s the big deal? The difference is that a random-character password is the gold standard of security. It’s better than any human-chosen password could be. It will still be good even if everyone in the world adopts this scheme.

A random-character password of reasonable length is, for practical purposes, unguessable with today’s technology. It won’t appear in a list of popular passwords. A mass attacker could guess a random password only in a brute-force search. With upper- and lowercase letters and numbers, there are sixty-two possible characters. (I won’t count punctuation marks, as not all sites allow them.) That means it would take 62^8 guesses to be certain of hitting an eight-character password. That’s over 218 trillion guesses.

That effectively rules out an Internet mass attack and would slow down a targeted attack. Accepting the claim that some forensic software can spit out 2.8 billion guesses a second, it would take about twenty-two hours to make that many guesses. That’s secure enough for most people—should you disagree, you’re welcome to add a few more characters.

The politics of Game of Thrones

I tried to read the Song of Fire and Ice by George R.R. Martin and couldn't get through much more than one book. The prose is rough, functional at best. 

The TV series, though, I love. The first book ended up reading like an adaptation of the first season of the series, so closely did the two hew to each other back then. It made sense to me to find out Martin had worked as a Hollywood screenwriter for much of the 80's and part of the 90's.

What Martin does do well, and what makes Game of Thrones more fascinating than much of the fantasy series out there, is delve deeply into realpolitik. Characters win or lose not so much based on whether they are good or bad in character as whether they're the smartest player in the political arena, the so-called "game of thrones." Thus we see many characters killed off in defiance of audience expectations. That's the part of the series that I love the most, beyond the high and increasing production values (a noticeable increase in quality after season one), beautiful locations (refreshing in this day and age of cartoonish digital backdrops to see the real world serve as the backdrop for so much of the series), and fun performances (there are some weak links, like Danaerys, but most of the lead performances are strong).

Martin also manages to challenge the audience's desire for clean moral judgments (with the exception of characters like Joffrey who seem horrific through and through).

Much of this comes out in a really good interview of Martin in Rolling Stone.

A major concern in A Song of Ice and Fire and Game of Thrones is power. Almost everybody – except maybe Daenerys, across the waters with her dragons – wields power badly. 

Ruling is hard. This was maybe my answer to Tolkien, whom, as much as I admire him, I do quibble with. Lord of the Rings had a very medieval philosophy: that if the king was a good man, the land would prosper. We look at real history and it's not that simple. Tolkien can say that Aragorn became king and reigned for a hundred years, and he was wise and good. But Tolkien doesn't ask the question: What was Aragorn's tax policy? Did he maintain a standing army? What did he do in times of flood and famine? And what about all these orcs? By the end of the war, Sauron is gone but all of the orcs aren't gone – they're in the mountains. Did Aragorn pursue a policy of systematic genocide and kill them? Even the little baby orcs, in their little orc cradles?

In real life, real-life kings had real-life problems to deal with. Just being a good guy was not the answer. You had to make hard, hard decisions. Sometimes what seemed to be a good decision turned around and bit you in the ass; it was the law of unintended consequences. I've tried to get at some of these in my books. My people who are trying to rule don't have an easy time of it. Just having good intentions doesn't make you a wise king.

...

Early on, one critic described the TV series as bleak and embodying a nihilistic worldview, another bemoaned its "lack of moral signposts." Have you ever worried that there's some validity to that criticism? 

No. That particular criticism is completely invalid. Actually, I think it's moronic. My worldview is anything but nihilistic.

Some of your most contemptible characters are also among the story's greatest truth-tellers. One of the most riveting moments in the TV series took place in the Battle of Blackwater episode, which you wrote the script for, when Sandor says to Sansa, "The world was built by killers, so you'd better get used to looking at them." 

Truth is sometimes hard to hear. Two of the central phrases are true, but they are not truths that most human beings like to contemplate. Winter is coming and Valar morghulis – all men must die. Mortality is the inescapable truth of all life . . . and of all stories, too.

Make it harder to cross the street

It turns out some of the key FCC people working to determine the future of net neutrality used to work at Comcast. The same path is also traveled in reverse quite frequently.

But overall, the FCC is one of many agencies that have fallen victim to regulatory capture. Beyond campaign contributions and other more visible aspects of the influence trade in Washington, moneyed special interest groups control the regulatory process by placing their representatives into public office, while dangling lucrative salaries to those in office who are considering retirement. The incentives, with pay often rising to seven and eight figure salaries on K Street, are enough to give large corporations effective control over the rule-making process.

...

The revolving door, however, provides a clear and semi-legal way for businesses to directly give unlimited cash and gifts to officials who act in their favor. One of the most famous examples of this dynamic is the case of Meredith Attwell Baker, an FCC Commissioner who left her job right after voting in favor of the Comcast merger with NBC. Her next career move? She became a high-level lobbyist for Comcast, the company she had just blessed. Earlier this week, she announced her next gig, as president of CTIA, the primary wireless industry trade group. She’ll have her work cut out for her in lobbying her former colleagues. CTIA has already warned the FCC from taking up any new net neutrality regulations.
 

In a democracy, if you don't want the money of corporations completely taking over policy-making, you can't allow people leaving office to immediately cross the street to a corner office on K-Street with a huge salary, and you also shouldn't allow those public officials to go work for a company in an industry they were regulating before. It's much too simple a way to essentially offer a deferred bribe.

Unbelievable but true facts

A trillion is a gigantic number. Really, really gigantic, but most people can't truly understand the difference between a million, a billion, and a trillion because those numbers are almost unfathomable.
So instead of using money to describe numbers, I'm going to use time. I fudged some dates or numbers to use major events; forgive me.
1 (one) second ago, you started reading this sentence.

More of these in this Reddit thread. Another classic:

The number of ways to shuffle a deck of cards is 80,658,175,170,943,878,571,660,636,856,403,766,975,289,505,440,883,277,824,000,000,000,000.
 

To wit, “There are more ways to shuffle a deck of cards then there are atoms in our solar system.” Or, for a more impressive party conversation trick, have someone shuffle a deck of cards and then note that the arrangement of cards they just produced has likely never been seen in the history of the universe.

Narrative framing in restaurant reviews

Researchers analyzed over 900,000 online restaurant reviews to understand how people structured positive and negative reviews from a narrative perspective.

Negative reviews, especially in expensive restaurants, were more likely to use features previously associated with narratives of trauma: negative emotional vocabulary, a focus on the past actions of third person actors such as waiters, and increased use of references to “we” and “us”, suggesting that negative reviews function as a means of coping with service–related trauma. Positive reviews also employed framings contextualized by expense: inexpensive restaurant reviews use the language of addiction to frame the reviewer as craving fatty or starchy foods. Positive reviews of expensive restaurants were long narratives using long words emphasizing the reviewer’s linguistic capital and also focusing on sensory pleasure. Our results demonstrate that portraying the self, whether as well–educated, as a victim, or even as addicted to chocolate, is a key function of reviews and suggests the important role of online reviews in exploring social psychological variables.
 

Anyone who's spent some time reading restaurant reviews on Yelp will feel a pang of recognition. Perhaps taking a restaurant to task after a poor service experience is a cathartic way of dealing with the trauma, explaining why someone might take the time to write yet another review when a restaurant on Yelp already has hundreds or thousands of reviews.

In summary, one–star reviews were overwhelmingly focused on narrating experiences of trauma rather than discussing food, both portraying the author as a victim and using first person plural to express solace in community.
 

The narrative style of the hyperbolic negative restaurant review, with its first person framing, has made them well-suited to serving as dramatic monologues.

On positive reviews of inexpensive restaurants:

Whether there is in fact a biochemical link between junk food cravings and drug addiction is an open question in the literature [4]. Nonetheless, our results suggest that the folk model of this belief is productive and widespread in consumer reviews. Hormes and Rozin (2010) found that participants rated the words “craving” and “addiction” in various languages as being most appropriately applied to drugs, alcohol, or food. Our study extends these results to show that the metaphor of food as an addiction or craving tends to apply to a particular subset of foods. The foods that are “craved” are foods that are in some way non–normative: they are meaty, sugary, starchy foods, generally fast food and street food, or small snack–like inexpensive ethnic foods. Craved foods aren’t vegetables, or main courses like meatloaf or fish or even side dishes like mashed potatoes. The folk model of what we crave or are addicted to encompasses foods that are somehow considered inappropriate for a meal, bad for you (unhealthily full of fats and sugars), inexpensive, comfort food that we feel guilty for having but eat anyhow.

The result that women are more likely to use this metaphor in our data is also consistent with previous results. Rozin, et al. (1991) found that females are significantly more likely to express cravings for chocolate than males. Zellner, et al. (1999), Weingarten and Elston (1990), and Osman and Sobal (2006) found that female undergraduates were more likely than males to report food cravings. Our results do not distinguish among the possible causes of the greater number of these expressions by female reviewers: women might be more likely than men to have these cravings or feelings, women might be more comfortable than men to admitting to these cravings, or women might simply be more likely than men to use this particular linguistic metaphor to describe their otherwise identical desires.
 

This makes intuitive sense. Most people are more likely to eat more affordable food repeatedly and thus describe them as an addictive substance. I wonder if the prevalent discussion of the health risks of of meaty, starchy foods contributes to the language of addiction when describing them; guilt and addiction are so entwined.

Positive reviews of expensive restaurants use a different narrative framing.

We first examined review features linked with educational capital. Education is strongly associated with differences in socioeconomic status, and in fact is one of the main ways that class status is defined in social scientific studies, along with work and income. Previous work on food advertising found that advertising of more expensive products employs longer, more complex words and longer sentences (Freedman and Jurafsky, 2011), presumably because complex words or sentences signal the writers’ higher educational capital, and hence project higher social status. We therefore tested whether this use of more complex language to project “linguistic capital” was similarly associated with price in reviews, predicting that reviews more expensive restaurants would be longer and use longer words.

The second feature we investigate frames food as a sensual or even sexual pleasure. This tendency is widespread in expensive wine reviews, which make extensive use of phrases like sexy, sensual, seductive, voluptuously textured, ravishing, and hedonistic (Lehrer, 2009; McCoy, 2005; Shesgreen, 2003). Television food commercials in the United States also emphasize “sensual hedonism” with words like luscious, indulgent, irresistible, and decadent (Strauss, 2005). We therefore expected reviews of expensive restaurants to use words related to sex or sensuality.
 

The data confirmed their hypotheses.

I wonder how much of this narrative framing results from some level of confirmation bias. If you spend so much on a restaurant meal, you're going to feel great pressure to justify your decision, and describing the meal with more more complex words and longer sentences might be one way to justify your expense as having led to a more sophisticated, sensual experience.
