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.

Automated installation script of MediaSPIP
25 avril 2011, parTo 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.

Uploading video to Twitter sometimes doesn't work
22 juillet 2021, par K-s S-kI have a very difficult situation. I've already spent 2 days and couldn't find a solution. Project on Laravel. I want to upload videos to Twitter using the Twitter API endpoints. But sometimes I am getting this error :




file is currently unsupported




I did everything as recommended in the official documentation Video specifications and recommendations. I get an error when I set an audio codec is aac in my video file, despite the fact that it is recommended in the official documentation, but when I set the audio codec to mp3, the video is uploaded, but the sound quality is very poor, and sometimes there is no sound at all. Please forgive me if this is awkward to read, but I want to provide all of my code. Because I don't know how to solve this anymore and I think it might help.
