    "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

Implementing a quantum approximate optimization algorithm on a 53-qubit NISQ device - 0 views

  •  
    A large team of researchers working with Google Inc. and affiliated with a host of institutions in the U.S., one in Germany and one in the Netherlands has implemented a quantum approximate optimization algorithm (QAOA) on a 53-qubit noisy intermediate-scale quantum (NISQ) device. In their paper published in the journal Nature Physics,, the group describes their method of studying the performance of their QAOA on Google's Sycamore superconducting 53-qubit quantum processor and what they learned from it. Boaz Barak with Harvard University has published a News & Views piece on the work done by the team in the same journal issue.

What does home mean if your bed is on the pavements of Paris? | Aeon Essays - 0 views

  • The American anthropologist Edward Fischer, paraphrasing Aristotle, said that the good life is ‘a life worth living’, or a journey towards ‘a fulfilled life’. It has to do with happiness but is not limited to it; it’s often – perhaps counterintuitively – linked to commitment and sacrifice, to the work of becoming a particular person. The French philosopher Michel Foucault in 1982 described these practices as technologies of the self. According to Foucault, the self is ‘not given to us … we have to create ourselves as a work of art’. My informants on the streets of Paris were striving – in their own ways – towards being better selves. I came to understand the activities, processes and routines that they engaged in – begging, making a shelter, accessing temporary housing, etc – as practices of the self geared towards a better life, as practices of homemaking on the street, as practices of hope.
  • Aside from François, others I met on the streets of Paris – such as Sabal from India, and Alex from Kosovo – talked about their engagement in such practices of hope. Following them through soup kitchens, drop-in centres, government institutions and homeless shelters, I observed two main ways in which they attempted to push for a better life. Both of them were connected to the idea of home: my informants in Paris were longing to find and go back to a homeland, often one from the past, while on a daily basis they were struggling to construct a home in order to survive. That was what a better life looked like for them.
  • Home, according to the Australian social scientist Shelley Mallett, is always suspended between the ideal and the real. It relates to ‘the activity performed by, with or in person’s things and places. Home is lived in the tension between the given and the chosen, then and now.’ While Sabal’s India was part of the ideal, what Alex was dealing with was closer to the ‘real’ side of this distinction. His home-making efforts were a continuous process of daily activities.

  • For many of the homeless people I’ve met in both London and Paris, home was connected to a place they departed from and have a desire to return to – a place that carried what the English sociologist Liz Kenyon calls a right to return and a sense of one’s origin. Sara Ahmed’s 1999 study of migrants’ writing, particularly Asian women living in Britain, supports this view of home as something in the longer-term future. The British-Australian scholar wrote that home is often a destination, somewhere to travel to: ‘the space which is most like home, which is most comfortable and familiar, is not the space of inhabitance – I am here – but the very space in which one finds the self as almost, but not quite, at home. In such a space, the subject has a destination, an itinerary, indeed a future, but in having such as destination, has not yet arrived.’ Home is, in this sense, not about the present – and surely not a place of passive suffering – but about one’s hopes, about making home an imagined place where one has not yet arrived.
  • Home is exactly such a process, involving the material and the imaginative, social connections and mundane acts. Routines, habits and rhythms – often as simple as regularly visiting certain neighbourhoods, shelters and food kitchens – are important parts of this process, and are deeply connected to a temporal as well as spatial order. This focus on order is best expressed in the classical analysis of home by the English anthropologist Mary Douglas:[Home] is always a localisable idea. Home is located in space but it is not necessarily a fixed space. It does not need bricks and mortar, it can be a wagon, a caravan, a board, or a tent. It need not be a large space, but space there must be, for home starts by bringing some space under control.
  • François, who introduced me to the labour of begging, found something close to home in his daily practices. His home was fashioned by coming face to face with the city around him. These narratives show how far removed these people are from a state of passive suffering. Yes, there were moments of idleness and, for some, long phases of pain. But most of the people I met sleeping rough – independent of age, gender, tenure on the street and level of addiction – were striving, in their way, towards a better life: first on, and hopefully off, the street.

It's not all Pepes and trollfaces - memes can be a force for good - The Verge - 0 views

    "How the 'emotional contagion' of memes makes them the internet's moral conscience By Allie Volpe Aug 27, 2018, 11:30am EDT Illustration by Alex Castro & Keegan Larwin SHARE Newly single, Jason Donahoe was perusing Tinder for the first time since it started integrating users' Instagram feeds. Suddenly, he had an idea: follow the Instagram accounts of some of the women he'd been interested in but didn't match with on the dating service. A few days later, he considered taking it a step further and direct messaging one of the women on Instagram. After all, the new interface of the dating app seemed to encourage users to explore other areas of potential matches' online lives, so why not take the initiative to reach out? Before he had a chance, however, he came across the profile of another woman whose Tinder photo spread featured a meme with Parks and Recreation character Jean-Ralphio Saperstein (Ben Schwartz) leaning into the face of Ben Wyatt (Adam Scott) with the caption: hey I saw you on Tinder but we didn't match so I found your Instagram you're so beautiful you don't need to wear all that makeup ahah I bet you get a lot of creepy dm's but I'm not like all those other guys message me back beautiful btw what's your snap "I was like, 'Oh shit, wow,'" Donahoe says. Seeing his potential jerk move laid out so plainly as a neatly generalized joke, he saw it in a new light. "I knew a) to be aware of that, and b) to cut that shit out … It prompted self-reflection on my part." THE MOST SUCCESSFUL MEMES STRIKE A CULTURAL CHORD AND CAN GUIDE AND EVEN INFLUENCE BEHAVIOR Donahoe says memes have resonated with him particularly when they depict a "worse, extreme version" of himself. For Donahoe, the most successful memes are more than just jokes. They "strike a societal, cultural chord" and can be a potent cocktail for self-reflection as tools that can guide and even influence behavior. In the months leading up to the 2016 US

Causal Inference Book | Miguel Hernan | Harvard T.H. Chan School of Public Health - 0 views

  •  
    "My colleague Jamie Robins and I are working on a book that provides a cohesive presentation of concepts of, and methods for, causal inference. Much of this material is currently scattered across journals in several disciplines or confined to technical articles. We expect that the book will be of interest to anyone interested in causal inference, e.g., epidemiologists, statisticians, psychologists, economists, sociologists, political scientists, computer scientists… The book is divided in 3 parts of increasing difficulty: causal inference without models, causal inference with models, and causal inference from complex longitudinal data. We are making drafts of selected book sections available on this website. The idea is that interested readers can submit suggestions or criticisms before the book is published. To share any comments, please email me or visit @causalinference on Facebook. To cite the book, please use "Hernán MA, Robins JM (2018). Causal Inference. Boca Raton: Chapman & Hall/CRC, forthcoming.""
