I am running an Ubuntu based LEMP mail/web server, using MariaDB. When I run the command

sudo service mariadb status

I get the following warnings:

Could someone please explain what exactly is happening here, how to debug this, and how to fix these warnings? Is this a security issue or a functionality issue? Any elaboration, explanation, and solution here, would be highly appreciated.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
