  • J – 55: Une amie m’offre un recueil de poèmes de Charles Reznikoff, poète américain dont j’ignorais tout et qui, pour ce qui se trouve dans ce recueil, a collecté de nombreuses minutes de toutes sortes de petits procès, et opérant de très savants collages a écrit des poèmes remarquables à la fois de musicalité mais aussi de peinture d’un réel à la fois sombre et de petites choses.

    Désolé de ne pas être traducteur, un métier, un métier que je ne pourrais jamais exercer, pas plus, finalement que celui de berger de chèvres en Ardèche, même limites évidentes de manque de compétence, aussi le poème qui suit est dans sa langue maternelle. Et un livre de poèmes que je puisse poser en cavalier sur ma table de chevet, finalement c’est un peu ce qui manquait à mon bonheur ces derniers temps. Une lecture du soir et des violettes.

    DOMESTIC SCENES
    Adams and his wife, Hester, and their three small children
    were living on a farm about a mile from the James River.
    Abingdon was the renter of the farm;
    but he was a trapper—
    had a number of traps along both sides of the river—
    and had hired Adams and Casper Dill
    to do the farm work for a share of the crops.
    Abingdon was unmarried and lived in a room of the house
    where Adams and his wife lived;
    Dill lived with his old crippled mother—
    who could not get about—
    in a small house nearby.
    One evening, Abingdon said he was planning a trip across the river
    to “take” a bee tree.
    They were in the house of Mrs. Dill,
    the four of them, Abingdon, Adams, and the Dills;
    Adams was unwilling to go with Abingdon
    unless young Dill went along.
    Both Adams and Dill said they could not swim—
    everybody in the neighborhood knew that—
    and Dill said he did not like water more than knee-deep,
    and Adams nodded agreement.
    Dill added he would rather plow than go,
    but his mother said that since Mr. Abingdon was anxious for him to
    come he had better do so.
    The three men started in the morning
    with everything needed: two large buckets for the honey,
    two axes and a hatchet,
    and a piece of netting to protect them from the bees.
    The boat did not belong to Abingdon
    but he had a key to unlock the boat from its fastening
    to the bank. It was a small boat,
    about ten feet long and two and a half feet wide;
    Abingdon sat in the rear
    with his face to the front; and Adams and Dill sat in front of him,
    their faces also to the front and their backs to Abingdon.
    They landed on the other side of the river
    and went to the bee tree;
    but when they reached it, Abingdon, so he said,
    decided not to cut it down
    because it was a large tree
    and the hole small,
    and the tree might not have any honey in it, after all.
    On the way back, about fifty yards from the shore,
    the boat suddenly filled with water,
    and both Adams and young Dill were drowned.
    When the boat was gotten out of the water,
    three holes, freshly bored, each about an inch and a half in width, were found under the seat where Abingdon had been sitting; and fresh shavings, suiting the size of the holes and of the same
    wood the boat was made of, had been thrown into the water where the boat had been fastened but the shavings had drifted ashore.
    Here, too, were found corncobs cut to fit the holes in the boat. The morning after the drownings, when they came to arrest
    Abingdon, he was found in Hester Adams’ room—and bed.

  • La marine américaine teste des essaims de drones maritimes
    http://fcw.com/articles/2014/10/14/navy-swarm-boats.aspx
    La marine américaine réalise des avancées importantes pour des drones maritimes.

    The Office of Naval Research announced Oct. 5 that it demonstrated the swarming capability over the course of two weeks in August on the James River in southeastern Virginia. Those demonstrations involved as many as 13 boats that used either autonomous or remote control, the office said in its announcement.

    Underpinning the “swarm boats” is a technology called Control Architecture for Robotic Agent Command and Sensing. It is a combination of hardware and software that features a small circuit board that can turn a boat into an unmanned system. The Navy adapted parts of CARACAS from technology NASA used for the Mars rover programs.

    The demonstrations were “a cost-effective way to integrate many small, cheap and autonomous capabilities that can significantly improve our warfighting advantage,” Chief of Naval Operations Adm. Jonathan Greenert said in a statement.

    The Office of Naval Research said the drone boats “could revolutionize the way the service defends people, ports, waterways and commerce.”

    Le communiqué de l’armée américaine et sa vidéo insistent sur les capacités à fonctionner en « essaim » de ses drones maritimes, ce qui rappelle

    Le site Humanoïdes.fr précise ce fonctionnement en essaim de CARACaS :

    Non seulement le système contrôle la direction des bateaux, mais il coordonne également leur comportement envers les véhicules qui se trouvent autour.

    DefenseOne a consacré un long article à l’expérience :
    http://www.defenseone.com/technology/2014/10/inside-navys-secret-swarm-robot-experiment/95813

    Et revient tout particulièrement sur cette évolution du matériel militaire en essaim avec des robots nombreux peu coûteux. Une étude citée, qui va dans ce sens, laisse rêveur quant au futur que nous promet l’armée dans un monde où les guerres entre armées régulières sont devenues rares :

    In a recent report preview from the Center for New American Security, Paul Scharr and James Marshall described the transition to low-cost, more autonomous robotic systems as the force multiplier of the future. “Low-cost uninhabited systems offer a way to bring mass back to the fight. With no human onboard, they can take greater risk. Survivability can be balanced against cost, with swarm resiliency taking the place of platform survivability. Swarms of low-cost uninhabited systems can be used to saturate and overwhelm enemy defenses. The robotics revolution will enable new ways of bringing mass back on the battlefield.”

    Les drones terrestres en essaim pointent aussi leur nez à l’occasion d’un concours de robots « démineurs » (mais dont les fonctions possibles sont beaucoup plus larges)

    Parmi les stars de cette compétition dotée de 50 millions de dollars de prix, la startup israélienne Roboteam. L’armée israélienne a pu tester le déploiement de ses Micro Tactical Ground Robot cet été à Gaza, elle en a acheté une centaine :
