Why Is the World So Loud? – The Atlantic

November 2, 2019

QT:{{”
“Stéphane Pigeon, an audio-processing engineer based in Brussels, has become the Taylor Swift of white noise, traveling the world recording relaxing soundscapes for his website, myNoise.net, which offers its more than 15,000 daily listeners an encyclopedic compendium of noise-masking tracks that range from “Distant Thunder” to
“Laundromat,” a listener request. (White noise, technically speaking, contains all audible frequencies in equal proportion. In the natural world, falling rain comes close to approximating this pan-frequency shhhhhh.) Impulse noises, such as honking, barking, hammering, and snoring, are the hardest to mask, but Pigeon has tried: While traveling in the Sahara, he recorded “Berber Tent,” a myNoise hit designed to help snorees by harmonizing the gentle whoosh of wind, the burble of boiling water, and the low rattle of snoring.

Farther north on Flatbush Avenue, encircled by lowing horns and a wheezing Mister Softee truck, Kanuri used his sound-meter app to measure the ambient noise—a disappointing 75.9 decibels, lower than everyone had thought but still more than 20 decibels above the threshold at which, per a 1974 EPA report, we get distracted or annoyed by sound. (Decibels, which measure volume, are logarithmic: Turn up a sound by 10 decibels, and most people will perceive its loudness as having doubled.)

Desperate ears call for desperate measures, and the noise-afflicted go to elaborate lengths to lower the volume. Kanuri taught himself to code so he could analyze New York City’s 311 data and correlate noise complaints with elective districts; he hoped he could hold politicians accountable. … A Wisconsin man who’d re-insulated, re-drywalled, and re-windowed his home was ultimately offered sleeping medication and antidepressants. An apartment dweller in Beijing, fed up with the calisthenics of the kids upstairs, got revenge by attaching a vibrating motor to his ceiling that rattled the family’s floor. The gadget is available for purchase online, where you can also find Coat of Silence paint, AlphaSorb Bass Traps, the Noise Eater Isolation Foot, the Sound Soother Headband, and the Sonic Nausea Electronic Disruption Device, which promises, irresistibly, “inventive payback.”” “}}

Should internet firms pay for the data users currently give away?

October 14, 2019

QT:{{”
“Still, the paper contains essential insights which should frame discussion of data’s role in the economy. One concerns the imbalance of power in the market for data. That stems partly from concentration among big internet firms. But it is also because, though data may be extremely valuable in aggregate, an individual’s personal data typically are not. For one Facebook user to threaten to deprive Facebook of his data is no threat at all. So effective negotiation with internet firms might require collective action: and the formation, perhaps, of a “data-labour union”.

This might have drawbacks. A union might demand too much in
compensation for data, for example, impairing the development of useful AIs. It might make all user data freely available and extract compensation by demanding a share of firms’ profits; that would rule out the pay-for-data labour model the authors see as vital to improving data quality. Still, a data union holds potential as a way of solidifying worker power at a time when conventional unions struggle to remain relevant.”

Building a Career, One Academic Step at a Time

October 6, 2019

““The four-year undergraduate experience is often out of reach for large segments of our population,” said Kemi Jona, associate dean for digital innovation and enterprise learning at Northeastern University in Boston. Moreover, he said, “the idea of getting that one degree and you’re set for life doesn’t really hold water anymore. Then the question becomes, ‘how do we make it easier for working adults and people who need to pick up new kinds of tools and technologies?’”

The answer: stackable credits, which Cassandra Horii, director of Caltech’s center for teaching, learning and outreach, defined as “a more bite-sized piece of education that stands on its own and has value in the workplace.” But “if you continue on your educational trajectory, that piece fully counts towards your next educational step.”

The stackable term itself, noted Jimmie Williamson and Matthew Pittinsky in an article in “Inside Higher Education,” is “clever, invoking the image of Lego blocks and the metaphor of assembly.”” “}}

Biological composites—complex structures for functional diversity | Science

An example is the combination of rigidity and flexibility in protein-based teeth of the squid sucker ring. Other examples are time-delayed actuation in plant seed pods triggered by environmental signals, such as fire and water, and surface nanostructures that combine light manipulation with mechanical protection or water repellency. Bioinspired engineering transfers some of these structural principles into technically more relevant base materials to obtain new, often unexpected combinations of material properties. Less appreciated is the huge potential of using bioinspired structural complexity to avoid unnecessary chemical diversity, enabling easier recycling and, thus, a more sustainable materials economy.

How to stop data centres from gobbling up the world’s electricity

September 29, 2019

QT:{{”

“The savings made by hyperscale centres can be seen in their power usage efficiency (PUE), defined as the total energy needed for everything, including lights and cooling, divided by the energy used for computing (a PUE of 1.0 would be a perfect score). Conventional data centres typically have a PUE of about 2.0; for hyperscale facilities, that’s been whittled down to about 1.2. Google, for one, boasts a PUE of 1.12 on average for all its centres.

Older or less technologically adept data centres can contain a mix of equipment that is hard to optimize — and some that is even useless. In 2017, Jonathan Koomey, a California-based consultant and leading international expert on IT, surveyed with a colleague more than 16,000 servers tucked into corporate closets and basements and found that about one-quarter of them were “zombies”, sucking up power without doing any useful work — perhaps because someone simply forgot to turn them off. “These are servers sitting around doing nothing except using electricity, and that’s outrageous,” says Koomey.”
