  • Free Ride: Digital Parasites and the Fight for the Business of Culture | Brain Pickings

    "For my part, I started Brain Pickings more than six years ago as what’s commonly referred to as a “passion project” (though I don’t like the fleeting noncommittal relationship this phrasing suggests) and didn’t have a business model — but I did have a crystal-clear editorial model, which remains the same today: get people interested in meaningful cross-disciplinary things they didn’t yet know they were interested in, and in the process empower their networked knowledge and combinatorial creativity; break out of the filter bubble, if you will, though conceived long before we had the very vocabulary to articulate it. So when an aggregator like the Huffington Post, a business-model wolf wearing an editorial-authenticity sheep’s skin, takes my (ad-free) content and regurgitates it on its (ad-plastered) site, it lives up to the term “parasite” at the heart of Levine’s argument, derived from the Greek parasitos and used to describe “someone who ate at someone else’s table without providing anything in return.”"

  • Blogging Moby-Dick

    "The ship Pequod, too, was a vestige of an earlier phase of the whaling industry: "She was a ship of the old school, rather small if anything; with an old-fashioned claw-footed look about her." She was a ship trophied by past hunts, and named after "a celebrated tribe of Massachusetts Indians, now extinct as the ancient Medes." Matt Kish's portrait of the Pequod evokes its inimitability and intricacy, but Melville's own image is at least as fantastic."

  • Minivan of the Revolution » Blog Archive » And So It Begins

    "And yet, here I am. Fifty years old, irredeemably a bookseller, and more happy than if I’d…if I’d what? Well, than if I’d just about anything, I suppose. I’ll put it this way – if I were to win the lottery tomorrow, the only thing that would change would be the quality of my inventory. I just can’t imagine doing anything else. Even in those moments of blankest regret, when all the bills come due at once and my stock looks like it could have been chosen at random by a blind, crack-addicted three-year-old; when the office hasn’t been cleaned in a month and the coffee jitters set in because I forgot to eat my breakfast which is still sitting cold on the kitchen counter six hours later; when the phone rings and it’s some flea-market guy asking to “pick my brain” about a “real old book” he found buried in cowshit in his granddaddy’s barn; even when I get home after a house buy and realize that every book I just overpaid for smells irretrievably of cat piss…even then, I can only imagine one way forward: more books. And then, more books after that and, for dessert, more books. More books. More books. More books."

  • [1110.5376] A Quantitative Test of Population Genetics Using Spatio-Genetic Patterns in Bacterial Colonies

    "It is widely accepted that population genetics theory is the cornerstone of evolutionary analyses. Empirical tests of the theory, however, are challenging because of the complex relationships between space, dispersal, and evolution. Critically, we lack quantitative validation of the spatial models of population genetics. Here we combine analytics, on and off-lattice simulations, and experiments with bacteria to perform quantitative tests of the theory. We study two bacterial species, the gut microbe Escherichia coli and the opportunistic pathogen Pseudomonas aeruginosa, and show that spatio-genetic patterns in colony biofilms of both species are accurately described by an extension of the one-dimensional stepping-stone model. We use one empirical measure, genetic diversity at the colony periphery, to parameterize our models and show that we can then accurately predict another key variable: the degree of short-range cell migration along an edge. Moreover, the model allows us to estimate other key parameters including effective population size (density) at the expansion frontier. While our experimental system is a simplification of natural microbial community, we argue it is a proof of principle that the spatial models of population genetics can quantitatively capture organismal evolution."

  • The Performativity of Networks – Kieran Healy

    "The “performativity thesis” is the claim that parts of contemporary economics and finance, when carried out into the world by professionals and popularizers, reformat and reorganize the phenomena they purport to describe, in ways that bring the world into line with theory. Practical technologies, calculative devices and portable algorithms give actors tools to implement particular models of action. I argue that social network analysis is performative in the same sense as the cases studied in this literature. Social network analysis and finance theory are similar in key aspects of their development and effects. For the case of economics, evidence for weaker versions of the performativity thesis in quite good, and the strong formulation is circumstantially supported. Network theory easily meets the evidential threshold for the weaker versions; I offer empirical examples that support the strong (or “Barnesian”) formulation. Whether these parallels are a mark in favor of the thesis or a strike against it is an open question. I argue that the social network technologies and models now being “performed” build out systems of generalized reciprocity, connectivity, and commons-based production. This is in contrast both to an earlier network imagery that emphasized self-interest and entrepreneurial exploitation of structural opportunities, and to the model of action typically considered to be performed by economic technologies."

  • Classifying Heart Sounds Challenge

    "According to the World Health Organisation, cardiovascular diseases (CVDs) are the number one cause of death globally: more people die annually from CVDs than from any other cause. An estimated 17.1 million people died from CVDs in 2004, representing 29% of all global deaths. Of these deaths, an estimated 7.2 million were due to coronary heart disease. Any method which can help to detect signs of heart disease could therefore have a significant impact on world health. This challenge is to produce methods to do exactly that. Specifically, we are interested in creating the first level of screening of cardiac pathologies both in a Hospital environment by a doctor (using a digital stethoscope) and at home by the patient (using a mobile device).

    The problem is of particular interest to machine learning researchers as it involves classification of audio sample data, where distinguishing between classes of interest is non-trivial. Data is gathered in real-world situations and frequently contains background noise of every conceivable type. The differences between heart sounds corresponding to different heart symptoms can also be extremely subtle and challenging to separate. Success in classifying this form of data requires extremely robust classifiers. Despite its medical significance, to date this is a relatively unexplored application for machine learning."
