  • An OCR cliche: Into his/her anus
    https://wraabe.wordpress.com/2009/03/07/an-ocr-cliche-into-hisher-anus

    Because the letters “rm” resemble “nu,” the OCR algorithm frequently mistakes them.

    Examples:

    Wives and Daughters: An Every-day Story‎ – Page 519
    by Elizabeth Cleghorn Gaskell – 1890 – 637 pages
    When the old servant opened the door, a lady with a child in her anus stood there. She gasped out her ready-prepared English sentence. …

    Dr. William Smith’s Dictionary of the Bible: Comprising Its Antiquities …‎ – Page 1824
    by William George Smith, Horatio Balch Hackett, Ezra Abbot – Bible – 1888
    Then she carried the child in her anus to her people; but they said that it was a strange thing she had done.


  • Optical Character Recognition With #google Cloud Vision API
    https://hackernoon.com/optical-character-recognition-with-google-cloud-vision-api-255bb8241235?

    Lately, I’ve been working on a delivery tracking application on React/React Native. One of the features is to allow a user to take a picture of a shipping label on your phone, and translate that label into a tracking number we can work with on the back end. The goal of this feature is to minimize the time spent to manually input tracking numbers, which range from 13–26 characters long depending on the service. In my quest to implement this feature, I came across a technique known as optical character recognition and an incredible image recognition toolkit from Google. In this article, I’ll go over the basics of how this method works, and how to integrate it into your application.What is Optical Character Recognition?Optical Character Recognition (OCR for short) is a technique that (...)

  • Chrome Extension With Over One Million Users Hijacked to Serve Adware
    https://www.bleepingcomputer.com/news/security/chrome-extension-with-over-one-million-users-hijacked-to-serve-adw

    The developer of a very popular Google Chrome extension has regained access over his tool after an unknown hacker had managed to hijack his developer account and push a malicious version that contained adware.

    The extension’s name is Web Developer, a tool developed by Chris Pederick, Director of Engineering at Bleacher Report. The extension overlays a popup with various debug tools that developers can use when building or editing their websites.

    Over the weekend, someone compromised another Chrome extension in the same way. The owners of Copyfish — on OCR extension for Google Chrome — also fell for a phishing email and someone took over their developer account. The hijackers did the same thing and used the developers’ account to push a malicious update that inserted ads on the websites Copyfish users were trying to view.

  • Citizen Maths: free, open mathematical literacy for everyone / Boing Boing
    http://boingboing.net/2016/06/06/citizen-maths-free-open-math.html

    Citizen Maths is a free open online Level 2 maths course for people who want to improve their grasp of maths. We’ve been developing Citizen Maths over the last two years, with funding from the Ufi Charitable Trust, working with the UCL Institute of Education, and OCR (part of Cambridge Assessment), and with advice from the Google Course Builder team. The overwhelming bulk of Citizen Maths is CC-BY licensed, meaning that others can reuse the content with ease.

    We have designed Citizen Maths using the OECD’s PISA 2015 Mathematics Framework, which defines the mathematical literacy assessed in the Programme for International Student Assessment (PISA).

    We chose the PISA framework partly because of its international reach, and partly because it has been based on the view that a “growing proportion of problems and situations encountered in daily life, including in professional contexts, require some level of understanding of mathematics, mathematical reasoning and mathematical tools, before they can be fully understood and addressed”. We therefore believe that someone who has learned maths through Citizen Maths will have gained economically and socially valuable skills in mathematics.

    We have just launched the final two parts of the course. These parts, which cover pattern and measurement, are added to existing parts on proportion, representation and uncertainty.

    Each part of the course covers one powerful idea in maths. Each has been designed to take between 5 and 10 hours to complete. Each shows the idea in action in several different contexts. For example, uncertainty involves the following situations:

    making decisions - value of insurance, risk comparisons;
    judging - the meaning of cancer screening results;
    gaming - appreciating odds in roulette, dice, horse-racing;
    modelling - the uncertain prediction of the weather.






  • #Cancer Culture - S. Lochlann Jain
    https://anthropology.stanford.edu/people/lochlann-s-jain

    Usually cancer is studied as a distinct, finite, disease that some unfortunate people get. Nevertheless, over half of all Americans will be diagnosed with an invasive cancer. In this book, based in extensive analysis of the history, politics, and science of cancer, as well as years of fieldwork, I examine the ways that cancer is not separate from, but is central to medical, political, and social economies.

      Did my mind declare war on my body ?

      J’ai passé un peu de temps pour mettre le pdf en texte ici (en OCR car ce sont des images du livre de mauvaise qualité), de manière à ce qu’il puisse être lu par les non anglophones. J’ai corrigé les premières pages, si j’ai le courage je ferais la suite au fur et à mesure.
      Dans tous les cas, ce texte méritait d’être diffusé, j’espère que l’auteur sera d’accord.

      I don’t blame people for not knowing how to engage with a person with cancer.
      How would they? Heck, I hadn’t either. Despite the fact that each
      year 70,000 Americans between the ages of fifteen and forty are diagnosed
      with the disease and that incidence in this age group has doubled in the last
      thirty years, many of my friends in their thirties have never had to deal with
      it on a personal level.

      I remember when my cousin Elise was undergoing chemotherapy treatment while in her early thirties. When I met her I couldn’t even mention it,
      couldn’t (or wouldn’t, or didn’t) say that I was sorry or ask her how it was
      going---even though it was so obviously the thing that was going on. I was
      thirty-five for God’s sake, a grown—up, a professional, a parent, and cancer
      was so unthinkable that I couldn’t even acknowledge her disease. When my
      former partner’s sister showed up at our house all bald after her chemotherapy, my only remark was, “Hey, you could totally be a lesbian.” I was terrified,
      or in denial. More likely I had picked up the culture of stigma and this disabled me from giving genuine acknowledgment. But whatever sympathetic spin you want to put on it, I sucked in all the ways that I had to learn how to deal with later. Indeed, an assumption of exceptionalism was only the flip side of my own shame.

      Fantasies of agency steep both sides of diagnosis. On the “previvor” side,
      images continually tell us that cancer can be avoided if you eat right, avoid
      Teflon and smoking, and come from strong stock. Alternatively, tropes of
      hope, survivorship, battling, and positive attitude are fed to people post-
      diagnosis as if they were at the helm of a ship in known waters, not along
      stormy and uncharted shores. And yet, so little of cancer science, patient
      experience, or survival statistics seems to provide backing for the ubiquitous
      calls for hope in the popular culture of cancer. After all, who would celebrate
      a survivor who did not stand amid at least a few poor SOBs who fell?

      Everyone who has "battled,” “been touched by,” “survived,” been “made
      into a shadow of a former self,” or has been called to inhabit the myriad can-

      car cliches has been asked to live in a caricature. As poets say in rendering
      their craft, clichés serve to shut down meaning. Clichés allow us not to think
      about What we are describing or hearing about: we know roses are red. People
      with cancer are called to live in and through—even if recalcitrantly—these
      hegemonic clichés by news articles, TV shows, detection campaigns, patient
      pamphlets, high—tech protocol—driven treatments, hospital organizations and
      smells, and everyday social interactions. Such cultural venues as marches
      for hope, research funding and direction, pharmaceutical interests, survivor
      rhetoric, and hospital ads constitute not distinct cultural phenomena, but
      overlap to form a broader hegemony of ways that cancer is talked about and
      that in turn control and diminish the ways that cancer culture can be inhab-
      ited and spoken about. Cancer exceeds the biology of multiplying cells. But
      the paradoxes of cancer culture can also be used to reflect on broader Ameri—
      can understandings of health and the mismatch of normative assumptions
      with the ways people actually live and die. "lhe restricted languages of cancer
      are not innocent.

      For an example of how individuated agency is used in cancer, one might
      look to the massive literature and movement spurred by Bernard Siegel,
      which is based in the moral complex of cancer and what he describes as the
      “exceptional patient.” In Love, Medicine, and Miracles: Lessons Learned about
      Self—Healing from a Surgeon’s Experience with Exceptional Patients, Siegel
      writes about having the right attitude to survive cancer(1). In Siegel’s View and
      its variants, surviving cancer becomes a moral calling, as if dying indicates
      some personal failure. Siegel—style literature offers another form of torture
      to people with cancer: Did my mind declare war on my body? Am I a cold,
      repressed person? (Okay, don’t answer that.) This huge and punishing industry preys on fear as much as any in the cancer complex and adds guilt to the mix.
      As one woman with metastatic colon cancer said on a retreat I attended,
      “Maybe I haven’t laughed enough. But then I looked around the room and
      some of you laugh a lot more than I do and you’re still here.” She died a year
      later, though she laughed plenty at the retreat.

      It’s no wonder that shame is such a common response to diagnosis. The
      dictionary helps with a description of shame: “The painful emotion arising
      from the consciousness of something dishonoring, ridiculous, or indecorous in one’s own conduct or circumstances, or of being in a situation which
      offends one’s sense of modesty or decency.(2)” Indeed, cancer does offend. People in treatment are often advised to wear wigs and other disguises, to joke
      with colleagues; they are given tips on how to make others feel more at ease.
      One does want to present decency, to seem upbeat. And so do others. A quick

      “you look good,” with a response of “oh, thanks,” offers a Welcome segue to
      the next discussion topic and enables a certain propriety to circumscribe the
      confusion of proper responses to illness, to the stigma embodied by the possibility of a short life and a painful death. One person with metastatic disease
      calls herself, semi-facetiously, “everyone’s worst nightmare.” Others Speak
      about how hard it is to see the celebration of survivors while knowing that
      they themselves are being killed by the disease.

      Social grace is a good thing. But given the scope of the disease --- half of all
      Americans die of it and many more go through treatment --- one might wonder what or whom such an astonishing cultural oversight serves. After all how can cancer, a predictable result of an environment drowning in indus:
      trial and military toxicity, be dishonoring or indecorous ? I don’t mean its
      side effects; the physical breakdown of the body is perhaps definitive of the
      word “indecorousf” But these pre- and post-diagnosis calls to disavowal can
      help illuminate the ugly underside of American’s constant will to health, its
      normative assumptions about health and the social) individual, and generational traumas that it propagates. Expectations and assumptions about life span and their discriminatory and generational effects offer but one of many venues for such an exploration.

      Survivorship in America

      Perhaps it’s a class issue, but I didn’t really think about survival until I was
      called to consider being in the position of the one who might be survived.
      I was just tootling along until I was invited by diagnosis to inhabit this category, to attend retreats, camps, and support groups, to share an infusion
      room—to do all kinds of things with many people who have not, in fact,
      survived cancer—and thus to survive them at their memorial services, the
      garage sales of their things> and in the constructing and reading of memorial
      Websites and obituaries.

      To be sure, cancer survivorship (as opposed to either cancer death or
      just plain survival) comes with its benefits. I got a free kayak, albeit with a
      leak. When things are going really wrong I think about how my life insur-
      ance could pay for some cool things for my kids, or that maybe I don’t have
      to worry about saving for a down payment since in order for a home to be
      , a good investment you should really plan to live in it for five years. Some-
      times,when you find yourself buying into those cancer mantras of living in
      the moment, you can look around from a superior place at all the people
      scurrying around on projects you have determined do not matter—and then
