    28 novembre 2010, par

    Une file d’attente stockée dans la base de donnée

  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • FFmpeg conversion to Photo-JPEG is blocky [duplicate]

    26 mai 2017, par Richard210363

    This question already has an answer here :

    I am converting .mp4 files to .mov with the Photo-JPEG codec to use in After Effects to reduce render times.

    I have looked up the FFmpeg commands to do this and come up with :

    ffmpeg -i tower-bridge.mp4 -an -pix_fmt yuvj420p -vcodec mjpeg -f mov -y tower-bridge.mov

    This works but when I look at the output video it is quite blocky ; like a mosaic.

    During the conversion I get this message :

    [swscaler @ 0000000008c97fe0] deprecated pixel format used, make sure you did set range correctly

    Research on-line suggests I can ignore this message.

    What can I do to improve the output quality ?

  • French CNIL recommends Piwik : the only analytics tool that does not require Cookie Consent

    29 octobre 2014, par Matthieu Aubry — Press Releases

    There has been recent and important changes in France regarding data privacy and the use of cookies. This blog post will introduce you to these changes and explain how you make your website compliant.

    Cookie Consent in the data freedom law

    Since the adoption of the EU Directive 2009/136/EC “Telecom Package”, Internet users must be informed and provide their prior consent to the storage of cookies on their computer. The use of cookies for advertising, analytics and social share buttons require the user’s consent :

    It is necessary to inform users of the presence, purpose and duration of the cookies placed in their browsers, and the means at their disposal to oppose it.

    What is a cookie ?

    Cookies are tracers placed on Internet users’ hard drives by the web hosts of the visited website. They allow the website to identify a single user across multiple visits with a unique identifier. Cookies may be used for various purposes : building up a shopping cart, storing a website’s language settings, or targeting advertising by monitoring the user’s web-browsing.

    Which cookies are exempt from the Cookie Consent rule ?

    France has exempted certain cookies from the cookie consent rule : for those cookies that are strictly necessary to offer the service sought after by the user you do not need to ask consent to user. Examples of such cookies are :

    • the shopping cart cookie,
    • authentication cookies,
    • short lived session cookies,
    • load balancer cookies,
    • certain first party analytics (such as Piwik cookies),
    • persistent cookies for interface personalisation.

    Asking users for consent for Analytics (tracking) Cookies

    For all cookies that are not exempted from the Cookie Consent then you will need to :

    • obtain consent from web users before placing or reading cookies and similar technologies,
    • clearly inform web users of the different purposes for which the cookies and similar technologies will be used,
    • propose a real choice to web users between accepting or refusing cookies and similar technologies.

    You don’t need Cookie Consent with Piwik

    The excellent news is that there is a way to bypass the Cookie Consent banner on your website :

    If you are using another analytics solution other than Piwik then you will need to ask users for consent. If you do not want to ask for consent then download and install Piwik or signup to Piwik Cloud to get started.

    If you are already using Piwik you need to do two simple things : (1) anonymise visitor IP addresses (at least two bytes) and (2) include the opt-out iframe solution in your website (learn more).

    Note that these recommendations currently only apply in France, but because the law is European we can expect similar findings in other European countries.

    CNIL recommends Piwik

    We are proud that the CNIL has identified Piwik as the only tool that respects all privacy requirements set by the European Telecom law.

    About the CNIL

    The CNIL is an independent administrative body that operates in accordance with the French data protection legislation. The CNIL has been entrusted with the general duty to inform people of the rights that the data protection legislation allows them.

    The role and responsabilities of the CNIL are :

    • to protect citizens and their data
    • to regulate and control processing of personal data
    • to inspect the security of data processing systems and applications, and impose penalties

    Piwik and Privacy

    At Piwik we love Privacy – our open analytics platform comes with built-in Privacy.

    Future of Privacy at Piwik

    Piwik is already the leader when it comes to respecting user privacy but we plan to continue improving privacy within the open analytics platform. For more information and specific ideas see Privacy enhancing issues in our issue tracker.
