Les tâches Cron régulières de la ferme
1er décembre 2010, parLa gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
Le super Cron (gestion_mutu_super_cron)
Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...) -

La sauvegarde automatique de canaux SPIP
1er avril 2010, parDans 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 (...)

Issues with processing media on windows Azure
23 septembre 2015, par Ahmed MujtabaI have a website built on ASP.NET web forms that works as a media portal for users to upload videos. I’m using ffmpeg encoders to produce video contents to be streamed in the browser. I’m using the web deploy method to publish the site on the Azure server. The website get’s deployed properly however I get following issues in the live site.
-
Video never get’s encoded and published. I get some sort of error.
-
Video get’s published but the process of uploading and encoding the video is way too slow on the web server.
My project solution contains upload.ashx that handles the upload requests and makes the call to encode.ashx which is responsible for the encoding and publishing of the videos. I tried to remotely debug the site but the debugger never get’s to encode.ashx.
I was wondering if these issues can be resolved by having the website deployed with a VM ?
