Vivaldi does not Support the opensearch protocol to automatically add new search engines to Vivaldi. Therefore we need to add a custom search engine, to add our (selfhosted) SearXNG instance, to Vivaldi. To enable SearXNG as a search engine with working autocompletion you only need these two values: URL: https://your-searxng.tld/search?q=%s Suggest URL: https://your-searxng.tld/autocompleter?q=%s You can now use Vivaldi with your own SearXNG instance. If you have not yet set up your own SearXNG instance, you can find some publicly accessible instances at searx....

One part consists of a .timer file, and a .service file. The .timer file specifies when our service should be started. Just like a cronjob we can specify here on which days, in which week or at which time our service should be started....

Backups are sometimes not quite present in our everyday life, but if we suddenly face a problem there is nothing but a backup that can save us. In the past, I have mounted the data from MariaDB (or MySQL) containers using Docker on a specific Docker volume and backed it up daily. Depending on the database engine, this data may or may not be consistent.
