  • « L'open-source fonctionne grâce à l'égoïsme » pas grâce à l'altruisme, Linus Torvalds ajoute l'importance de la confiance

    « L'open-source fonctionne grâce à l'égoïsme » Pas grâce à l'altruisme explique Linus Torvalds, qui souligne l'importance de la confiance Linus Torvald vient de recevoir de l'Académie des Sciences de Finlande le prix Millennium Technology, doté de 600.000 euros, pour l'ensemble de son oeuvre sur le noyau Linux. Un noyau qu'il a inventé et qu'il n'a, depuis, jamais cessé de maintenir avec l'aide d'une communauté de plus en plus nombreuse. Ce prix a été l'occasion pour l'informaticien finlandais (désormais américain) de donner une interview à la BBC. Comme à son habitude, le technique y côtoie la provocation. Il le concède d'ailleurs lui-même, son tempérament asocial expliqu...

    <b>Policy Fugue:</b> "Comcast CEO Brian Roberts headed back to Capitol Hill on Thursday to defend his company's proposed merger with NBC Universal, offering what by now are familiar assurances that the combined company won't use its market power to bully smaller cable competitors, raise prices for consumers or restrict access to Internet video."

  • « La frénésie mobile gagne les applications mainframe », pour Micro Focus cette évolution poserait de nouveaux problèmes

    La frénésie mobile gagnerait les applications mainframe Pour Micro Focus, ce qui ne serait pas sans poser de nouveaux défis Pour Patrick Rataud, Directeur général de Micro Focus Gallia, la multiplication des accès mobiles aux applications mainframe s'avèrerait inévitable. Mais elle poserait une double question : le SI est-il compatible avec ces nouvelles approches ? Et comment éviter l'explosion des coûts mainframe du fait de leur sur sollicitation ? De plus en plus, particuliers et professionnels veulent accéder en permanence depuis leur appareil mobile à toutes les applications qu'ils ont l'habitude d'utiliser sur leur PC fixe ou portable. IDC estime que le nombre de téléchargements d'applicati...

  • Unable to connect to Samba printer

    - by user127236
    I have a headless Ubuntu 12.04 server for files and printers. It shares files via Samba just fine. However, the HP PSC-750xi connected to the server via USB is not accessible from my Ubuntu 12.04 laptop. I can browse for it in the Printing control panel, but any attempt to authenticate my ID to the printer with my user credentials results in the error "This print share is not accessible". I have included the Samba smb.conf file below. Any help appreciated. Thanks... JGB # # Sample configuration file for the Samba suite for Debian GNU/Linux. # # # This is the main Samba configuration file. You should read the # smb.conf(5) manual page in order to understand the options listed # here. Samba has a huge number of configurable options most of which # are not shown in this example # # Some options that are often worth tuning have been included as # commented-out examples in this file. # - When such options are commented with ";", the proposed setting # differs from the default Samba behaviour # - When commented with "#", the proposed setting is the default # behaviour of Samba but the option is considered important # enough to be mentioned here # # NOTE: Whenever you modify this file you should run the command # "testparm" to check that you have not made any basic syntactic # errors. # A well-established practice is to name the original file # "smb.conf.master" and create the "real" config file with # testparm -s smb.conf.master >smb.conf # This minimizes the size of the really used smb.conf file # which, according to the Samba Team, impacts performance # However, use this with caution if your smb.conf file contains nested # "include" statements. See Debian bug #483187 for a case # where using a master file is not a good idea. # #======================= Global Settings ======================= [global] log file = /var/log/samba/log.%m passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* . obey pam restrictions = yes map to guest = bad user encrypt passwords = true passwd program = /usr/bin/passwd %u passdb backend = tdbsam dns proxy = no writeable = yes server string = %h server (Samba, Ubuntu) unix password sync = yes workgroup = WORKGROUP syslog = 0 panic action = /usr/share/samba/panic-action %d usershare allow guests = yes max log size = 1000 pam password change = yes ## Browsing/Identification ### # Change this to the workgroup/NT-domain name your Samba server will part of # server string is the equivalent of the NT Description field # Windows Internet Name Serving Support Section: # WINS Support - Tells the NMBD component of Samba to enable its WINS Server # wins support = no # WINS Server - Tells the NMBD components of Samba to be a WINS Client # Note: Samba can be either a WINS Server, or a WINS Client, but NOT both ; wins server = w.x.y.z # This will prevent nmbd to search for NetBIOS names through DNS. # What naming service and in what order should we use to resolve host names # to IP addresses ; name resolve order = lmhosts host wins bcast #### Networking #### # The specific set of interfaces / networks to bind to # This can be either the interface name or an IP address/netmask; # interface names are normally preferred ; interfaces = 127.0.0.0/8 eth0 # Only bind to the named interfaces and/or networks; you must use the # 'interfaces' option above to use this. # It is recommended that you enable this feature if your Samba machine is # not protected by a firewall or is a firewall itself.

    Diaspora se pose comme solution libre face à Facebook, le réseau social aGPL et décentralisé a-t-il une chance de succès ? Google n'est pas le seul à se faire des ennemis parmi les organisations européennes. Facebook est également dans leur ligne de mire avec sa politique "inacceptable" concernant la protection de la vie privée de ses utilisateurs. Le 12 mai, le groupe de travail 29 (du numéro de l'article concerné) de l'Union européenne -chargé de la protection des données personnelles- a publié une lettre ouverte qui attaque violemment le leader des réseaux sociaux (plus de 450 millions de membres dont 15 millions en France) en lui reprochant de monétiser les données qu'on lui confie (en laissant les moteurs de recherch...

    L'Internet en 3D arrivera d'ici 5 ans d'après Intel, est-ce le futur du web ? Sean Koehl travaille chez Intel en tant que "techno évangéliste". Il s'est réccemment exprimé au sujet du futur d'Internet, et il estime que le réseau "sera complètement différent d'ici 5 à 10 ans". Selon lui, notre manière d'interagir entre nous, et avec des appareils électroniques, va changer. Radicalement. Ainsi, il prédit l'émergence d'une technologie tri-dimensionnelle très réaliste dans 5 ans. Comme de plus en plus de gens autour du monde s'équipent avec des ordinateurs ou des smartphones et ont un accès à l'Internet. Sean explique qu'on commence seulement à exploiter toute cette puissance informatiq...
