La file d’attente de SPIPmotion
28 novembre 2010, parUne file d’attente stockée dans la base de donnée
Lors de son installation, SPIPmotion crée une nouvelle table dans la base de donnée intitulée spip_spipmotion_attentes.
Cette nouvelle table est constituée des champs suivants : id_spipmotion_attente, l’identifiant numérique unique de la tâche à traiter ; id_document, l’identifiant numérique du document original à encoder ; id_objet l’identifiant unique de l’objet auquel le document encodé devra être attaché automatiquement ; objet, le type d’objet auquel (...) -
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 (...)

Decode mp3 using FFMpeg, Android NDK - What is wrong with my AVFormatContext ?
27 février 2020, par michpohlI am trying to decode am MP3 file to a raw PCM stream using FFMpeg via JNI on Android. I have compiled the latest FFMpeg version (4.2) and added it to my app. This did not make any problems.
The goal is to be able to use mp3 files from the device’s storage for playback with oboeSince I am relatively inexperienced with both C++ and FFMpeg, my approach is based upon this :
oboe’s RhythmGame exampleI have based my
FFMpegExtractorclass on the one found in the example here. With the help of StackOverflow theAAssetManageruse was removed and instead aMediaSourcehelper class now serves as a wrapper for my stream (see here)But unfortunately, creating the AVFormatContext doesn’t work right - and I can’t seem to understand why. Since I have very limited understanding of correct pointer usage and C++ memory management, I suspect it’s most likely I’m doing something wrong in that area. But honestly, I have no idea.

Switch to Matomo for WordPress from Google Analytics
While Google Analytics may seem like a great plugin option on the WordPress directory, we’d like to present a new ethical alternative called Matomo for WordPress, which gives you 100% data ownership and privacy protection.
Firstly what does Google Analytics offer in WordPress ?
When you think of getting insights about visitors on your WordPress (WP) sites, the first thing that comes to mind might be Google Analytics. Why not right ? Especially when there are good free Google Analytics plugins, like Monster Insights and Site Kit.
These give you access to a great analytics platform, but the downside with Google Analytics is the lack of transparency around privacy and data ownership.
Matomo Analytics for WordPress is an ethical alternative to Google Analytics for WordPress
If you’re more interested in a privacy-respecting, GDPR compliant alternative, there’s now a new option on the WP plugins directory : Matomo Analytics – Ethical Stats. Powerful Insights.It’s free and can be considered the #1 ethical alternative to Google Analytics in terms of features and capabilities. Why is it important to choose a web analytics platform that respects privacy ?
Risk facing fines for non-GDPR compliance and privacy/data breaches
In Europe there’s an overarching privacy law called GDPR which provides better privacy protection for EU citizens on the web.
Websites need to be GDPR compliant and follow rules governing how personal data is used or risk facing fines up to 4% of their yearly revenue for data/privacy breaches or non-compliance. Even if your website is based outside of Europe. If you have visitors from Europe, you can still be liable.
In the US, there isn’t one main privacy law, there hundreds on both the federal and state levels to protect the personal data (or personally identifiable information) of US residents – like the California Consumer Privacy Act (CCPA). There are also industry-specific statutes related to data privacy like HIPAA.
To protect your website from coming under fire for privacy breaches, best practise is to find platforms that are privacy and GDPR compliant by design.
When you own your own data – as with the case of Matomo – you have control over where data is stored, what you’re doing with it, and can better protect the privacy of your visitors.
At this point you may be asking, “what’s the point of an analytics platform if you have to follow all these rules ?”
The importance of analytics for your WordPress site
- Figuring out how your audience behaves to increase conversions
- Setting, tracking and measuring conversion goals
- Being able to find insights to improve and optimize your site
- Making smarter, data-driven decisions so your company can thrive, rather than risk being left behind
Analytics is used to answer questions like :
- Where are your website visitors coming from (location) ?
- How many people visit your website ?
- Which are the most popular pages on your site ?
- What sources of traffic are coming to your site (social, marketing campaigns, search) ?
- Is your marketing campaign performing better this month compared to last ?
Matomo can answer all of the above questions. BONUS : On top of that, with Matomo you get the peace of mind knowing you’re the only one who has access to those answers.
