  • Invisible Images (Your Pictures Are Looking at You)
    http://thenewinquiry.com/essays/invisible-images-your-pictures-are-looking-at-you
    Super article, très important. À lire.

    When you put an image on Facebook or other social media, you’re feeding an array of immensely powerful artificial intelligence systems information about how to identify people and how to recognize places and objects, habits and preferences, race, class, and gender identifications, economic statuses, and much more.

    Neural networks cannot invent their own classes; they’re only able to relate images they ingest to images that they’ve been trained on. And their training sets reveal the historical, geographical, racial, and socio-economic positions of their trainers.

    Ideology’s ultimate trick has always been to present itself as objective truth, to present historical conditions as eternal, and to present political formations as natural. Because image operations function on an invisible plane and are not dependent on a human seeing-subject (and are therefore not as obviously ideological as giant paintings of Napoleon) they are harder to recognize for what they are: immensely powerful levers of social regulation that serve specific race and class interests while presenting themselves as objective

    as capital searches out new domains of everyday life to bring into its sphere, the ability to use automated imaging and sensing to extract wealth from smaller and smaller slices of everyday life is irresistible. It’s easy to imagine, for example, an AI algorithm on Facebook noticing an underage woman drinking beer in a photograph from a party. That information is sent to the woman’s auto insurance provider, who subscribes to a Facebook program designed to provide this kind of data to credit agencies, health insurers, advertisers, tax officials, and the police. Her auto insurance premium is adjusted accordingly. A second algorithm combs through her past looking for similar misbehavior that the parent company might profit from.

    Machine-machine systems are extraordinary intimate instruments of power that operate through an aesthetics and ideology of objectivity, but the categories they employ are designed to reify the forms of power that those systems are set up to serve. As such, the machine-machine landscape forms a kind of hyper-ideology that is especially pernicious precisely because it makes claims to objectivity and equality.

  • Lucky find offers our first look at a dinosaur tail, complete with feathers | Ars Technica
    http://arstechnica.com/science/2016/12/lucky-find-offers-our-first-look-at-a-dinosaur-tail-complete-with-feath

    Geoscientist Lida Xing was shopping at an amber market in Myitkyina, Myanmar in 2015 when he saw an unusual piece of amber. Trapped inside was a small object that the amber merchants thought was a sprig of leaves. But Xing thought something much more interesting was going on (…) eight fully preserved vertebrae from a young, non-avian dinosaur called a coelurosaur. As an adult it would have been about the size of an ostrich, but this juvenile was still tiny enough to get trapped in tree sap and never escape. Feathers covered its tail, but at the tip they fluffed out in a pattern that suggested this animal may have had a fan-shaped tail.

    (…)

    Bristol University paleobiologist Jacob Vinther told NPR’s Rae Ellen Bichell that this structure also meant that colorful, iridescent feathers may have evolved before ones capable of flight.

  • New style : conveyor belt flows

    The QGIS map style I want to share with you today was inspired by a hand-drawn map by Philippe Rekacewicz that I saw on Twitter.

  • Non, on n’a certainement pas encore touché le fond avec ces histoires de fake news. Continuons à creuser : Facebook and Google make lies as pretty as truth - How AMP and Instant Articles camouflage fake news
    http://www.theverge.com/2016/12/6/13850230/fake-news-sites-google-search-facebook-instant-articles

    The fake news problem we’re facing isn’t just about articles gaining traffic from Facebook timelines or Google search results. It’s also an issue of news literacy — a reader’s ability to discern credible news. And it’s getting harder to tell on sight alone which sites are trustworthy. On a Facebook timeline or Google search feed, every story comes prepackaged in the same skin, whether it’s a months-long investigation from The Washington Post or completely fabricated clickbait.
    While feed formatting isn’t anything new, platforms like Google AMP, Facebook Instant Articles, and Apple News are also further breaking down the relationship between good design and credibility. In a platform world, all publishers end up looking more similar than different. That makes separating the real from the fake even harder.

  • Is the electoral college fair ? - Washington Post

    https://www.washingtonpost.com/graphics/politics/how-fair-is-the-electoral-college/img/electoral-college-promo.jpg

    The electoral college isn’t a perfect system, and with two of the past five presidential elections going to the candidate who didn’t win the popular vote, calls to abolish the centuries-old system may get louder.

  • Filesystem cache for Drupal

    by Fil4 June 2013

    This is a drop-in replacement for Drupal 6’s cache system. We avoid a lot of problems by using a filesystem-cache in lieu of the classic database-cache. Our site with Drupal 6.26 (published 2012-05-02) kept crashing because it filled its `cache_menu` table too quickly. This is a drop-in replacement for includes/cache.inc that makes Drupal use a filesystem-based cache instead of the database.

  • Réparer le charset d’une base SPIP

    par Fil30 décembre 2012

    Quand on part d’une vieille installation de SPIP il arrive qu’on enregistre les données en utf-8 dans des tables déclarées en latin1. Ca ne gêne pas le fonctionnement normal du site, mais ça empêche d’utiliser proprement les outils MySQL, de la ligne de commande (qui affiche des « é » à la place des « é ») au moteur de recherche FULLTEXT, qui ne retrouve pas les mots accentués. Méthode de nettoyage. 0/ Faire toutes les sauvegardes, travailler sur un site de tests, etc. La procédure prend plusieurs minutes. (...)

    DotSPIP est une application pour Mac OS X qui permet de convertir facilement des fichiers texte de tout type vers les raccourcis SPIP. DotSPIP s’utilise simplement par glisser-déposer : on lâche un fichier, ou une série de fichiers, sur l’icone, et le résultat arrive à la fois à l’écran et dans le presse-papiers. Il ne reste plus qu’à le coller dans SPIP. Ce logiciel est en version bêta : il est loin d’être totalement mûr, mais déjà utilisable (et utilisé !). Lien de téléchargement : Après (...)

  • Terminer l’installation de Varnish

    par Fil10 avril 2011

    Ce qui suit est peut-être un peu abscons, mais il faut bien en passer par là pour terminer l’installation : tester la communication, passer Apache sur un port secondaire, passer Varnish en frontal, et fignoler. Maintenant que notre serveur sait communiquer avec Varnish, on va passer ce dernier en « frontal » sur le port http standard (:80). On dira à Apache d’écouter un port secondaire (:8080). Les visiteurs interrogeront donc Varnish, qui ira le cas échéant interroger Apache. Ultimes (...)
