    "With each interaction, Alexa is training to hear better, to interpret more precisely, to trigger actions that map to the user's commands more accurately, and to build a more complete model of their preferences, habits and desires. What is required to make this possible? Put simply: each small moment of convenience - be it answering a question, turning on a light, or playing a song - requires a vast planetary network, fueled by the extraction of non-renewable materials, labor, and data. The scale of resources required is many magnitudes greater than the energy and labor it would take a human to operate a household appliance or flick a switch. A full accounting for these costs is almost impossible, but it is increasingly important that we grasp the scale and scope if we are to understand and govern the technical infrastructures that thread through our lives. III The Salar, the world's largest flat surface, is located in southwest Bolivia at an altitude of 3,656 meters above sea level. It is a high plateau, covered by a few meters of salt crust which are exceptionally rich in lithium, containing 50% to 70% of the world's lithium reserves. 4 The Salar, alongside the neighboring Atacama regions in Chile and Argentina, are major sites for lithium extraction. This soft, silvery metal is currently used to power mobile connected devices, as a crucial material used for the production of lithium-Ion batteries. It is known as 'grey gold.' Smartphone batteries, for example, usually have less than eight grams of this material. 5 Each Tesla car needs approximately seven kilograms of lithium for its battery pack. 6 All these batteries have a limited lifespan, and once consumed they are thrown away as waste. Amazon reminds users that they cannot open up and repair their Echo, because this will void the warranty. The Amazon Echo is wall-powered, and also has a mobile battery base. This also has a limited lifespan and then must be thrown away as waste. According to the Ay

The Boundary Between Our Bodies and Our Tech - Pacific Standard - 0 views

  • At the beginning of his recent book, The Internet of Us, Lynch uses a thought experiment to illustrate how thin this boundary is. Imagine a device that could implant the functions of a smartphone directly into your brain so that your thoughts could control these functions. It would be a remarkable extension of the brain's abilities, but also, in a sense, it wouldn't be all that different from our current lives, in which the varied and almost limitless connective powers of the smartphone are with us nearly 100 percent of the time, even if they aren't—yet—a physiological part of us.
  • The debate over what it means for us to be so connected all the time is still in its infancy, and there are wildly differing perspectives on what it could mean for us as a species. One result of these collapsing borders, however, is less ambiguous, and it's becoming a common subject of activism and advocacy among the technologically minded. While many of us think of the smartphone as a portal for accessing the outside world, the reciprocity of the device, as well as the larger pattern of our behavior online, means the portal goes the other way as well: It's a means for others to access us.
  • "This is where the fundamental democracy deficit comes from: You have this incredibly concentrated private power with zero transparency or democratic oversight or accountability, and then they have this unprecedented wealth of data about their users to work with," Weigel says. "We've allowed these private companies to take over a lot of functions that we have historically thought of as public functions or social goods, like letting Google be the world's library. Democracy and the very concept of social goods—that tradition is so eroded in the United States that people were ready to let these private companies assume control."

  • Lynch, the University of Connecticut philosophy professor, also believes that one of our best hopes comes from the bottom up, in the form of actually educating people about the products that they spend so much time using. We should know and be aware of how these companies work, how they track our behavior, and how they make recommendations to us based on our behavior and that of others. Essentially, we need to understand the fundamental difference between our behavior IRL and in the digital sphere—a difference that, despite the erosion of boundaries, still stands."Whether we know it or not, the connections that we make on the Internet are being used to cultivate an identity for us—an identity that is then sold to us afterward," Lynch says. "Google tells you what questions to ask, and then it gives you the answers to those questions."

Originally published at the Institute for New Economic Thinking website Across the globe, a collective freak-out spanning the whole political system is picking up steam with every new "surprise" election, rush of tormented souls across borders, and tweet from the star of America's great unreality show, Donald Trump. But what exactly is the force that seems to be pushing us towards Armageddon? Is it capitalism gone wild? Globalization? Political corruption? Techno-nightmares? Rajani Kanth, a political economist, social thinker, and poet, goes beyond any of these explanations for the answer. In his view, what's throwing most of us off kilter - whether we think of ourselves as on the left or right, capitalist or socialist -was birthed 400 years ago during the period of the Enlightenment. It's a set of assumptions, a particular way of looking at the world that pushed out previous modes o

Optimization is as hard as approximation - Machine Learning Research Blog - 0 views

  •  
    Optimization is a key tool in machine learning, where the goal is to achieve the best possible objective function value in a minimum amount of time. Obtaining any form of global guarantees can usually be done with convex objective functions, or with special cases such as risk minimization with one-hidden over-parameterized layer neural networks (see the June post). In this post, I will consider low-dimensional problems (imagine 10 or 20), with no constraint on running time (thus get ready for some running-times that are exponential in dimension!).

Detecting Regions At Risk for Spreading COVID-19 Using Existing Cellular Wireless Netwo... - 0 views

  •  
    Goal: The purpose of this article is to introduce a new strategy to identify areas with high human density and mobility, which are at risk for spreading COVID-19. Crowded regions with actively moving people (called at-risk regions) are susceptible to spreading the disease, especially if they contain asymptomatic infected people together with healthy people. Methods: Our scheme identifies at-risk regions using existing cellular network functionalities-handover and cell (re)selection-used to maintain seamless coverage for mobile end-user equipment (UE). The frequency of handover and cell (re)selection events is highly reflective of the density of mobile people in the area because virtually everyone carries UEs. Results: These measurements, which are accumulated over very many UEs, allow us to identify the at-risk regions without compromising the privacy and anonymity of individuals. Conclusions: The inferred at-risk regions can then be subjected to further monitoring and risk mitigation.

Realignment and Legitimacy - 1 views

  • “The Constitutional Crisis Is Now” [Robert Reich, The American Prospect]. “If [Trump] refuses to accept the results [the 2020] election, as he threatened to do if he lost the 2016 election, he will have to be forcefully removed from office.” This is lunacy. In 2016, liberal Democrats floated the idea that “faithless electors” in the Electoral College should not appoint Trump — based on information from the “intelligence community” that the public was not allowed to see. From that day to this, liberal Democrats haven’t accepted the results of 2016, which is what the “Clinton won the popular vote” amounts to. Is the inability to look in the mirror a 10%-er deformation professionnelle?
  • “The Democratic Party unraveling is not good for America” [Ed Rogers, WaPo]. “The Democratic Party is not functioning as an umbrella organization or even a coalition. Instead, activists from Tom Steyer to George Soros to Planned Parenthood are operating independently*, doing things a political party otherwise would. These independent actors are pushing pet causes. Traditional party building isn’t one of them. Campaign finance reform and communication technologies have empowered wealthy individuals and collateral groups while at the same time inhibiting parties and individual campaigns. I say this not to kick the Democratic Party while it is down but because I believe in the two-party system…. We need reforms that empower parties and candidates and diminish the influence of deep-pocketed plutocrats and narrowly focused interest groups.” Rogers is a veteran of the Reagan and Bush White Houses, but he’s not wrong. NOTE * Maybe. When you start thinking, it’s hard to know where the boundaries of the Democrat Party really are. For example, are journalists who propagate Brock talking points in the party, or not? My instinct is to say that they are, but how is an institution with fluid boundaries like that to be named and categorized? Or how about an organization like Emily’s List, ostensibly independent, but directing donors only to Democrats? (And Donna Shalala, but not Alexandria Ocasio-Cortez. Or Cynthia Nixon. Or Zephyr Teachout. Really, Emily’s List? Really?)
  • UPDATE “One-time Ohio congressional district candidate arrested while streaming incident live on Facebook” [WHIOTV-7]. This is Sam Ronan, who ran for DNC chair and had good things to say about election rigging. The odd thing about this story, and everything I’ve seen on the Twitter, is that he was arrested at his house, and nobody is saying why the cops were there in the first place. Readers?

  • UPDATE “Maine Supreme Judicial Court rules ranked-choice voting unconstitutional” [Bangor Daily News]. From May, still germane: “In a unanimous, 44-page opinion issued Tuesday, the Maine Supreme Judicial Court’s seven justices agreed with Attorney General Janet Mills, Secretary of State Matthew Dunlap and Republican legislators that the system violates a provision of the Maine Constitution that allows elections to be won by pluralities — and not necessarily majorities — of votes.” The political establishment really, really hates RCV.

Radial flow system decouples reactions in automated synthesis of organic molecules - 0 views

  •  
    The synthesis of structurally complex organic molecules is the first task in the discovery of functional compounds needed for new technologies, including those in medicine and flexible electronics. Starting with relatively simple, purchasable reactants, the process involves sequences of chemical reactions in which the complexity of the molecules produced gradually increases with each step towards the final target. The sequences can be linear, or convergent (different parts of the target molecule are made in separate sequences and then joined together). To ensure that large amounts of the final product are prepared, each synthetic step must be high-yielding and reproducible, and must generate few side products.

Does Time Really Flow? New Clues Come From a Century-Old Approach to Math. | Quanta Mag... - 0 views

  •  
    Physicists who think carefully about time point to troubles posed by quantum mechanics, the laws describing the probabilistic behavior of particles. At the quantum scale, irreversible changes occur that distinguish the past from the future: A particle maintains simultaneous quantum states until you measure it, at which point the particle adopts one of the states. Mysteriously, individual measurement outcomes are random and unpredictable, even as particle behavior collectively follows statistical patterns. This apparent inconsistency between the nature of time in quantum mechanics and the way it functions in relativity has created uncertainty and confusion.

Trophic rewilding revives biotic resistance to shrub invasion | Nature Ecology & Evolution - 0 views

  •  
    Trophic rewilding seeks to rehabilitate degraded ecosystems by repopulating them with large animals, thereby re-establishing strong top-down interactions. Yet there are very few tests of whether such initiatives can restore ecosystem structure and functions, and on what timescales. Here we show that war-induced collapse of large-mammal populations in Mozambique's Gorongosa National Park exacerbated woody encroachment by the invasive shrub Mimosa pigra-considered one of the world's 100 worst invasive species-and that one decade of concerted trophic rewilding restored this invasion to pre-war baseline levels.

We May Be Closer to Full Employment Than It Seemed. That's Bad News. - The New York Times - 0 views

  •  
    What if those not seeking jobs are finding alternative ways to meet their basic needs outside of the reported job market? And does an increase in this number suggest that whatever systems they use to achieve such an end function in their favor, become more robust, and attract others to adopt them as well?

Scientists probe the role of archaea in the human microbiome - 0 views

  •  
    Numerous different microorganisms play an important role in the health and fitness, including humans, through their interactions with their host organism. The ability to enter into functional communication with the host also characterizes the archaea. They are basically known for their many special properties. Representatives of this group of microorganisms can also exist as so-called extremophiles under extraordinary living conditions, such as very high temperatures, high salt concentrations or in acidic environments.
