The Creative Apocalypse That Wasn’t

The Creative Apocalypse That Wasn’t http://www.nytimes.com/2015/08/23/magazine/the-creative-apocalypse-that-wasnt.html "The Napsterization of culture…less of a threat…than it initially appeared."

QT:{{"

“This would be even more troubling if independent bookstores — traditional champions of the literary novel and thoughtful nonfiction — were on life support. But contrary to all expectations, these stores have been thriving. After hitting a low in 2007, decimated not only by the Internet but also by the rise of big-box chains like Borders and Barnes & Noble, indie bookstores have been growing at a steady clip, with their number up 35 percent (from 1,651 in 2009 to 2,227 in 2015); by many reports, 2014 was their most financially successful year in recent memory.

How do we explain the evolutionary niche that indie bookstores seem to have found in recent years? It may be as simple as the tactile appeal of books and bookstores themselves. After several years of huge growth, e-book sales have plateaued over the past two years at 25 to 30 percent of the market, telegraphing that a healthy consumer appetite for print remains. To many of us, buying music in physical form is now simply an inconvenience: schlepping those CDs home and burning them and downloading the tracks to our mobile devices. But many of the most ardent Kindle converts — and I count myself among them — still enjoy browsing shelves of physical books, picking them up and sitting back on the couch with them.

….
If you believe the data, then one question remains. Why have the more pessimistic predictions not come to pass? One incontrovertible reason is that — contrary to the justifiable fears of a decade ago — people will still pay for creative works. The Napsterization of culture turned out to be less of a threat to prices than it initially appeared. Consumers spend less for recorded music, but more for live. Most American households pay for television content, a revenue stream that for all practical purposes didn’t exist 40 years ago. Average movie-­ticket prices continue to rise. For interesting reasons, book piracy hasn’t taken off the way it did with music.
….

The biggest change of all, perhaps, is the ease with which art can be made and distributed. The cost of consuming culture may have declined, though not as much as we feared. But the cost of producing it has dropped far more drastically. Authors are writing and publishing novels to a global audience without ever requiring the service of a printing press or an international distributor. For indie filmmakers, a helicopter aerial shot that could cost tens of thousands of dollars a few years ago can now be filmed with a GoPro and a drone for under $1,000; some directors are shooting entire HD-­quality films on their iPhones. Apple’s editing software, Final Cut Pro X, costs $299 and has been used to edit Oscar-­winning films. A musician running software from Native Instruments can recreate, with astonishing fidelity, the sound of a Steinway grand piano played in a Vienna concert hall, or hundreds of different guitar-­amplifier sounds, or the Mellotron proto-­synthesizer that the Beatles used on ‘‘Strawberry Fields Forever.’’ These sounds could have cost millions to assemble 15 years ago; today, you can have all of them for a few thousand dollars.”

We’ll see you, anon
http://www.economist.com/news/science-and-technology/21660966-can-big-databases-be-kept-both-anonymous-and-useful-well-see-you-anon “A dilemma. People want perfect #privacy & all the benefits of openness.” Math to the rescue?

Good for an intro. on privacy & attacks

QT:{{”

This is a true dilemma. People want both perfect privacy and all the benefits of openness. But they cannot have both.

“While some level of anonymisation will remain part of any resolution of the dilemma, mathematics may change the overall equation. One approach that would shift the balance to the good is homomorphic encryption, whereby queries on an encrypted data set are themselves encrypted. The result of any inquiry is the same as the one that would have been obtained using a standard query on the unencrypted database, but the questioner never sets eyes on the data. Or there is secure multiparty computation, in which a database is divided among several repositories. Queries are thus divvied up so that no one need have access to the whole database.

These approaches are, on paper, absolute in their protections. But putting them to work on messy, real-world data is proving tricky. Another set of techniques called differential privacy seems further ahead. The idea behind it is to ensure results derived from a database would look the same whether a given individual’s data were in it or not. It works by adding a bit of noise to the data in a way that does not similarly fuzz out the statistical results.


America’s Census Bureau has used differential privacy in the past for gathering commuters’ data. Google is employing it at the moment as part of a project in which a browser plug-in gathers lots of data about a user’s software, all the while guaranteeing anonymity. Cynthia Dwork, a differential-privacy pioneer at Microsoft Research, suggests a more high-profile proving ground would be data sets—such as some of those involving automobile data or genomes—that have remained locked up because of privacy concerns.”

No assembler required
http://www.economist.com/news/science-and-technology/21660077-how-teach-computer-science-nursery-school-no-assembler-required KIBO, Dash, Vortex & Hackaball provide a playful way to learn #programming

QT:{{”
Dr Umaschi Bers is not alone in that quest. KIBO, made by KinderLab Robotics (of which she is chief science officer when she is not doing her day job), is unusual only in that its instruction set is so tied to physical objects. Other toys being developed to teach young children the rudiments of programming use not wooden blocks but blocks of code, presented as icons of various sorts on the screens of tablets, smartphones and even old-fashioned PCs. Instead of being scanned, these instructions are uploaded wirelessly to the robots they are intended to control—robots that come in all sorts of shapes and sizes.

Some, like Vortex (a wheeled device that resembles a flattened motorcycle helmet) and Dash (a tetrahedron of spheres which, besides moving around at its programmer’s command, can also play tunes on a glockenspiel), are, like KIBO, designed mainly to scuttle across the living-room floor. Others, though, are heading in a different direction.

The Cobweb http://www.newyorker.com/magazine/2015/01/26/cobweb 20% of URLs in journal articles suffer from reference rot. Why we need a “Digital Vellum” & Web #archive

QT:{{”
Twitter is a rare case: it has arranged to archive all of its tweets at the Library of Congress. In 2010, after the announcement, Andy Borowitz tweeted, “Library of Congress to acquire entire Twitter archive—will rename itself Museum of Crap.”

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.

Copyright is the elephant in the archive. One reason the Library of Congress has a very small Web-page collection, compared with the Internet Archive, is that the Library of Congress generally does not collect a Web page without asking, or, at least, giving notice. “The Internet Archive hoovers,” Abbie Grotke, who runs the Library of Congress’s Web-archive team, says. “We can’t hoover, because we have to notify site owners and get permissions.” (There are some
exceptions.)

Also, it’s riddled with errors. One kind is created when the dead Web grabs content from the live Web, sometimes because Web archives often crawl different parts of the same page at different times: text in one year, photographs in another. In October, 2012, if you asked the Wayback Machine to show you what cnn.com looked like on September 3, 2008, it would have shown you a page featuring stories about the 2008 McCain-Obama Presidential race, but the advertisement alongside it would have been for the 2012 Romney-Obama debate.

Days of Our Digital Lives by @seththoughts http://www.nytimes.com/2015/07/05/opinion/sunday/seth-stephens-davidowitz-days-of-our-digital-lives.html #Search data shows misspellings & forgotten passwords more common at night

QT:{{"
“There is some evidence that we get less sharp as the day progresses. Between 2 and 3 a.m., search rates for “forgot password” are 60 percent higher than average. They are lowest around 9 a.m. Between 2 and 3 a.m., we are more than twice as likely to misspell “facebook” as “facbook” and nearly twice as likely to misspell “weather” as “wether.””

Why do we keep expecting robots to kill us?

Why do we…expect…robots to kill us?
http://mashable.com/2015/07/02/robot-killers/ Freak accident & coincidental reporting leads to skynet/#Terminator posts

QT:{{”
“The news flashed around the world, every headline a variation on the classic “man bites dog” — Robot Kills Man. To make matters more ominous, one of the reporters tweeting about the story was the Financial Times’ Sarah O’Connor — who was apparently unaware of the Terminator franchise featuring her namesake, Sarah Connor, and didn’t understand why so many of her replies talked about something called Skynet becoming self-aware.

Never mind that the robot in question was a relatively prosaic piece of machinery, a giant arm designed to operate within a cage, far away from humans. Never mind that, according to the preliminary assessment, the worker was at fault. Never mind that since the first robot-related death was reported in 1979, we’ve seen fewer than one such incident per year. Toilets, zippers and pants all cause more deaths than robots.

But we see what we want to see, and apparently what we want to see is the robopocalypse.”
