    "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

Diverse interactions and ecosystem engineering can stabilize community assembly | Natur... - 0 views

    The complexity of an ecological community can be distilled into a network, where diverse interactions connect species in a web of dependencies. Species interact directly with each other and indirectly through environmental effects, however to our knowledge the role of these ecosystem engineers has not been considered in ecological network models. Here we explore the dynamics of ecosystem assembly, where species colonization and extinction depends on the constraints imposed by trophic, service, and engineering dependencies. We show that our assembly model reproduces many key features of ecological systems, such as the role of generalists during assembly, realistic maximum trophic levels, and increased nestedness with mutualistic interactions. We find that ecosystem engineering has large and nonlinear effects on extinction rates. While small numbers of engineers reduce stability by increasing primary extinctions, larger numbers of engineers increase stability by reducing primary extinctions and extinction cascade magnitude. Our results suggest that ecological engineers may enhance community diversity while increasing persistence by facilitating colonization and limiting competitive exclusion.

Jane Jacobs's Theories on Urban Planning-and Democracy in America - The Atlantic - 0 views

  • Urban life was Jacobs’s great subject. But her great theme was the fragility of democracy—how difficult it is to maintain, how easily it can crumble. A city offered the perfect laboratory in which to study democracy’s intricate, interconnected gears and ballistics. “When we deal with cities,” she wrote in The Death and Life of Great American Cities (1961), “we are dealing with life at its most complex and intense.” When cities succeed, they represent the purest manifestation of democratic ideals: “Cities have the capability of providing something for everybody, only because, and only when, they are created by everybody.” When cities fail, they fail for the same reasons democracies fail: corruption, tyranny, homogenization, overspecialization, cultural drift and atrophy.
  • I was encouraged to believe that simple conformity results in stagnation for a society, and that American progress has been largely owing to the opportunity for experimentation, the leeway given initiative, and to a gusto and a freedom for chewing over odd ideas. I was taught that the American’s right to be a free individual, not at the mercy of the state, was hard-won and that its price was eternal vigilance, that I too would have to be vigilant.
  • Her 1,500-word speech, a version of which appears in Vital Little Plans, became the basis for The Death and Life of Great American Cities. Her main argument was Kirk’s: Small neighborhood stores, ignored by the planners in their grim demolition derby, were essential social hubs. She added that sidewalks, stoops, laundries, and mailbox areas were also indispensable centers of community activity, and that sterile, vacant outdoor space served nobody. “The least we can do,” she said, “is to respect—in the deepest sense—strips of chaos that have a weird wisdom of their own.”

  • Reduced to a word, Jacobs’s argument is that a city, or neighborhood, or block, cannot succeed without diversity: diversity of residential and commercial use, racial and socioeconomic diversity, diversity of governing bodies (from local wards to state agencies), diverse modes of transportation, diversity of public and private institutional support, diversity of architectural style. Great numbers of people concentrated in relatively small areas should not be considered a health or safety hazard; they are the foundation of a healthy community. Dense, varied populations are “desirable,” Jacobs wrote,
  • Madison argued that as you increase the “variety of parties and interests” contained within a republic, “you make it less probable that a majority of the whole will have a common motive to invade the rights of other citizens.”
  • “We need all kinds of diversity,” Jacobs concluded in Death and Life, “so the people of cities can sustain (and further develop) their society and civilization.”
  • In her comparative study of fallen empires, Jacobs identifies common early indicators of decline: “cultural xenophobia,” “self-imposed isolation,” and “a shift from faith in logos, reason, with its future-oriented spirit … to mythos, meaning conservatism that looks backwards to fundamentalist beliefs for guidance and a worldview.” She warns of the profligate use of plausible denial in American politics, the idea that “a presentable image makes substance immaterial,” allowing political campaigns “to construct new reality.” She finds further evidence of our hardening cultural sclerosis in the rise of the prison-industrial complex, the prioritization of credentials over critical thinking in the educational system, low voter turnout, and the reluctance to develop renewable forms of energy in the face of global ecological collapse.
  • In the foreword to the 1992 Modern Library edition of Death and Life, Jacobs likens cities to natural ecosystems. “Both types of ecosystems,” she writes, “require much diversity to sustain themselves … and because of their complex interdependencies of components, both kinds of ecosystems are vulnerable and fragile, easily disrupted or destroyed.”

  • uarterBack August 3, 2017 at 8:31 am Re NYT Hacking Wars story, I have long had the same “self-licking ice cream cone” concerns. The military industrial complex has been slowly shaping polic opinion to make “kenetic” response to cyber attacks palatable. Consider this 2013 article: https://armscontrolnow.org/2013/05/30/is-there-a-place-for-nuclear-deterrence-in-cyberspace/ Cyber as a Casus Belli has two inherent fatal flaws in its inability to accurately prove attribution and the extent of damage. The former makes it impossible to know if a counter attack is against a party that had any role in the original cyber attack, and the latter makes it impossible to prove or verify harm, which is the foundation of the “proportional response” required under the international laws of war. These two flaws can raise the potential of false flags to a new level. Do we really want to shed blood of untold numbers of military and civilian soles because of a report of a unattributable cyber attack on a purported “crital infrastructure component” that nobody every heard of,and that cannot be confirmed as existing in the first place? Gulf of Tonkin, eat your heart out. Look no further than our present history. We are slowly moving towards war with Russia based on the premise of a cyber attack that may, or may not, have actually happened, and no one has been allowed to inspect the physical servers related to the claimed attack. International laws of war should be clear that kenetic response to cyber attacks must be off the table. The only acceptable proportionate attacks should e economic or offensive cyber. Full stop.
