  • Pas question de marché, de cloud etc...

    10 avril 2011

    Le vocabulaire utilisé sur ce site essaie d’éviter toute référence à la mode qui fleurit allègrement
    sur le web 2.0 et dans les entreprises qui en vivent.
    Vous êtes donc invité à bannir l’utilisation des termes "Brand", "Cloud", "Marché" etc...
    Notre motivation est avant tout de créer un outil simple, accessible à pour tout le monde, favorisant
    le partage de créations sur Internet et permettant aux auteurs de garder une autonomie optimale.

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

  • Evolution #3973 : Brancher inc/distant recuperer_url() sur une librairie récente

    20 février 2019, par Eric Camus

    Bonjour,
    Suite à un changement de machine pour nos SPIP (de WIMP vers LAMP (centos)) de nombreux flux RSS ne fonctionnaient plus, la cause : la fonction ’recuperer_url’ !!!.
    J’ai donc réécrit le corps de cette fonction avec la biblio PHP CURL a partir du code dans SPIP 3.2.0 (je sais que je suis en retard d’une version).
    Je vous le livre comme je viens de le finir après un léger debug.

    Normalement, ce code doit être compatible avec l’ancienne fonction, il donne en plus en sortie [’range’] qui permet de savoir si un partial content peut être délivré.
    Il ne prend plus en compte les entrées [’refuser_gz’], [’version_http’] et [’boundary’] et l’entrée [’data’] doit être compatible avec celle de ’curl_setopt : CURLOPT_POSTFIELDS’.
    Si des gens veulent la tester et l’améliorer : bienvenue.

    Petit nota : SPIP laisse le fichier créer dans cette fonction ([’file’]) dans le tmp sans le détruire (version de base idem) : accumulation !
