Accounting for the gaps in ancient food webs - 0 views

  •  
    If you want to understand an ecosystem, look at what the species within it eat. In studying food webs-how animals and plants in a community are connected through their dietary preferences-ecologists can piece together how energy flows through an ecosystem and how stable it is to climate change and other disturbances. Studying ancient food webs can help scientists reconstruct communities of species, many long extinct, and even use those insights to figure out how modern-day communities might change in the future. There's just one problem: only some species left enough of a trace for scientists to find eons later, leaving large gaps in the fossil record-and researchers' ability to piece together the food webs from the past.

How Complex Web Systems Fail - Part 2 - Production Ready - Medium - 0 views

  •  
    "In his influential paper How Complex Systems Fail, Richard Cook shares 18 brilliant observations on the nature of failure in complex systems. Part 1 of this article was my attempt to translate the first nine of his observations into the context of web systems, i.e., the distributed systems behind modern web applications. In this second and final part, I'm going to complete the picture and cover the other half of Cook's paper. So let's get started with observation #10!"

    "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 Revenge of Dial-Up Internet | Fast Forward | OZY - 0 views

  • But what about Internet users who want to slow down, but their jobs won’t let them? People whose profession revolves around deadlines and time-sensitive material — journalists, bankers and many others — would be up in arms if the Internet slowed down even a split second, admits Carl Honoré, author of In Praise of Slow. “We’re up against the Web industrial complex,” he says, in which even the most well-intentioned businesses are driven by more content, more clicks, more swipes and ultimately getting more people addicted to their product. The Slow Web movement stands at odds with these realities. “That’s the big challenge,” Honoré says, “a kind of detoxification, a relearning of how to use the Web.”

Jeff Sessions is shamefully undermining WEB Du Bois's legacy | Marc Mauer - 0 views

  • Since 2002, the US Department of Justice’s WEB Du Bois program has sponsored research fellowships on issues of race and criminal justice. During Republican and Democratic administrations, a diverse group of academics have carried the spirit of the noted sociologist and civil rights leader to the race challenges of the 21st century. Given the racial disparity endemic at every stage of the justice system the DoJ’s investigation of these issues has been praiseworthy. But with Jeff Sessions as attorney general exploring the roots of this injustice may now be compromised. In the recently released solicitation for the Du Bois fellowships the DoJ invited scholars to engage in research on five issues arising out of the “tough on crime” era that would make a student of the Du Bois legacy shudder. Whereas Du Bois is widely known for promoting the idea that “the problem of the 20th century is the problem of the color line”, the DoJ solicitation displays no interest in such high-profile issues as police killings of unarmed black men or the impact of mass incarceration on the African American community. Instead, “protecting police officers” is the only area of law enforcement prioritized by the DoJ. Another research priority, “enhancing immigration enforcement”, coming at a moment when barely disguised racist imagery accompanies those policies, seems particularly jarring when upheld in the name of a civil rights legend. The DoJ approach to research is unfortunately consistent with the misconstrued “law and order” agenda that Jeff Sessions has brought to his leadership. Within a month of taking office Sessions had rescinded the Obama-era decision to phase out federal contracting with private prisons. That initiative had been based in part on an inspector general’s finding that such prisons had higher levels of assault and safety concerns than public prisons.

The Archdruid Report: When The Shouting Stops - 0 views

  •  
    "That said, there's another factor driving the reaction of Clinton's supporters, and the best way I can find to approach it is to consider one of the more thoughtful responses from that side of the political landscape, an incisive essay posted to Livejournal last week by someone who goes by the nom de Web "Ferrett Steinmetz." The essay's titled The Cold, Cold Math We'll Need to Survive the Next Twenty Years, and it comes so close to understanding what happened last Tuesday that the remaining gap offers an unsparing glimpse straight to the heart of the failure of the Left to make its case to the rest of the American people. At the heart of the essay are two indisputable points. The first is that the core constituencies of the Democratic Party are not large enough by themselves to decide who gets to be president. That's just as true of the Republican party, by the way, and with few exceptions it's true in every democratic society.  Each party large enough to matter has a set of core constituencies who can be counted on to vote for it under most circumstances, and then has to figure out how to appeal to enough people outside its own base to win elections. That's something that both parties in the US tend to forget from time to time, and when they do so, they lose. The second indisputable point is that if Democrats want to win an election in today's America, they have to find ways to reach out to people who don't share the values and interests of the Left. It's the way that Ferrett Steinmetz frames that second point, though, that shows why the Democratic Party failed to accomplish that necessary task this time. "We have to reach out to people who hate us," Steinmetz says, and admits that he has no idea at all how to do that. "
