  • Amélioration de la version de base

    13 septembre 2013

    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 (...)

  • Le plugin : Gestion de la mutualisation

    2 mars 2010, par

    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 :

  • Keeping control of your media in your hands

    13 avril 2011, par

    The vocabulary used on this site and around MediaSPIP in general, aims to avoid reference to Web 2.0 and the companies that profit from media-sharing.
    While using MediaSPIP, you are invited to avoid using words like "Brand", "Cloud" and "Market".
    MediaSPIP is designed to facilitate the sharing of creative media online, while allowing authors to retain complete control of their work.

  • Announcement : Piwik to focus on Reliability, Performance and Security

    7 octobre 2014, par Matthieu Aubry — About, Community

    To our valued team and community,

    Well, we have moved fast and achieved so much during the past few months. Relentlessly releasing major version after major version… We got a lot done including several major new features !

    The speed of adding new features was a great showcase of how agile our small teams and the larger community are. And I’m so proud to see automated testing becoming common practice among everyone hacking on Piwik !

    For the next few months until the new year we will focus on making what we have better. We will fix those rare but longstanding critical bugs, and aim to solve all Major issues and other must-have performance and general improvements. The core team and Piwik PRO will have the vision of making the existing Piwik and all plugins very stable and risk free. This includes edge cases, general bugs but also specific performance issues for high traffic or issues with edge case data payloads.

    We’ll be more pro-active and take Piwik platform to the next level of Performance, Security, Privacy & Reliability ! We will prove to the world that Free/Libre Web software can be of the highest standard of quality. By focusing on quality we will make Piwik even easier to maintain and improve in the future. We are building the best open platform that will let every user liberate their data and keep full control of it.

    If you have any feedback or questions get in touch or let’s continue the discussion in the forum.

    Thank you for your trust and for liberating your data with Piwik,

    Matthieu Aubry
    Piwik founder

    This is an amazing testament of the power of free/libre software and yet we think this is just the beginning. We hope more developers will join and contribute to the Piwik project !

  • swresample/resample : speed up build_filter by 50%

    swresample/resample : speed up build_filter by 50%

    This speeds up build_filter by 50%. This gain should be pretty
    
consistent across all architectures and platforms.
    

    Essentially, this relies on a observation that the filters have some
    
even/odd symmetry that may be exploited during the construction of the
    
polyphase filter bank. In particular, phases (scaled to [0, 1]) in [0.5, 1] are
    
easily derived from [0, 0.5] and expensive reevaluation of function
    
points are unnecessary. This requires some rather annoying even/odd
    
bookkeeping as can be seen from the patch.
    

    I vaguely recall from signal processing theory more general symmetries allowing even greater
    
optimization of the construction. At a high level, "even functions"
    
correspond to 2, and one can imagine variations. Nevertheless, for the sake
    
of some generality and because of existing filters, this is all that is
    
being exploited.
    

    Currently, this patch relies on phase_count being even or (trivially) 1,
    
though this is not an inherent limitation to the approach. This
    
assumption is safe as phase_count is 1 << phase_bits, and is hence a
    
power of two. There is no way for user API to set it to a nontrivial odd
    
number. This assumption has been placed as an assert in the code.
    

    To repeat, this assumes even symmetry of the filters, which is the most common
    
way to get generalized linear phase anyway and is true of all currently
    
supported filters.
    

    As a side note, accuracy should be identical or perhaps slightly better
    
due to this "forcing" filter symmetries leading to a better phase
    
characteristic. As before, I can’t test this claim easily, though it may
    
be of interest.
    

    Patch tested with FATE.
    

    Sample benchmark (x86-64, Haswell, GNU/Linux) :
    

    test : swr-resample-dblp-44100-2626
    

    new :
    
527376779 decicycles in build_filter(loop 1000),     256 runs,      0 skips
    
524361765 decicycles in build_filter(loop 1000),     512 runs,      0 skips
    
516552574 decicycles in build_filter(loop 1000),    1024 runs,      0 skips
    

    old :
    
974178658 decicycles in build_filter(loop 1000),     256 runs,      0 skips
    
972794408 decicycles in build_filter(loop 1000),     512 runs,      0 skips
    
954350046 decicycles in build_filter(loop 1000),    1024 runs,      0 skips
    

    Note that lower level optimizations are entirely possible, I focussed on
    
getting the high level semantics correct. In any case, this should
    
provide a good foundation.
