  • Amélioration de la version de base

    Jolie sélection multiple
    Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
    Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...)

  • Emballe médias : à quoi cela sert?

    4 February 2011, by

    Ce plugin vise à gérer des sites de mise en ligne de documents de tous types.
    Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel; un seul document ne peut être lié à un article dit "média";

  • Le plugin : Gestion de la mutualisation

    2 March 2010, by

    Le plugin de Gestion de mutualisation permet de gérer les différents canaux de mediaspip depuis un site maître. Il a pour but de fournir une solution pure SPIP afin de remplacer cette ancienne solution.
    Installation basique
    On installe les fichiers de SPIP sur le serveur.
    On ajoute ensuite le plugin "mutualisation" à la racine du site comme décrit ici.
    On customise le fichier mes_options.php central comme on le souhaite. Voilà pour l’exemple celui de la plateforme mediaspip.net :

  • Understanding CPU usage in linux using "top" command for VLC usage

    25 October 2014, by user3130013

    I have 2 quad core processors and I cant seem to understand what "top" is telling me.

    I run a VLC transcoding application and i currently transcode 8 streams and "top" shows me that I am using 200% of my CPU. Now for a Pentium 3 that would be horribly bad but I dont understand how Linux calculates CPU usage with multi core processors.

    Does this mean that my both processors are utilized 100%? 2 cores at 100%?

    I also ran ffmpeg application for the same purpose and I could run 8 instances at 90% each which seemed to me like each processoss would occupy 1 core.

    VLC has much lower CPU usage footprint so I just want to make sure I am not killing the hardware.
