With t3a.nano instance you got 512MB at a very reasonable price per month (around $5 / 4.5€ for an on-demand instance). It should be enough for running a micro wordpress blog with docker, but sometime it is not. A pair of docker containers can eat up all the memory and your little box will be unable to launch docker-compose shutdown commands with out of memory error all way around. But we are here to solve the issue, and get the best bang for your bucks :)

Docker was born for the cloud. It is the easiest way to run different software in a tiny box, installing it in a rapid way and with a nice way to wipe it in a snap. But when docker shines are the little docker compose files, which realize the Infrastructure as Code, a configuration file which declare in an easy and simple way how services are connected.

In 1985, all my work started with a VIC-20 with 5Kb of RAM, and only 3583 bytes free for the BASIC. With 3 more kilobytes, VIC-20 would be able to unveil its more versatile graphic capabilities, but we have no luck. In 1995 I got a 8 MegaBytes computer with 512MB hard disk as workstation for my University Exams. I was a lucky boy, and that PC helped me to graduate up to 2000.

Hosting your own email server is not a mandatory task; it increase your attack surface too. But relaying too much on big emails provider (Gmail, Outlook, Aruba, Fastmail) could be a risk for our democracy. For instance, who decide how Spam is managed (i.e. what could be a Spam email)? Can we trust big providers? Email has legal value, and its content should stay as much as private as possible.

How to monitor MySQL / MariaDB query progressThe progress indicator of MySQL or MariaDB long-running commands and queries is extremely extremely and frustratingly coarse. In an index update I’m running now it was stuck in the same state for more than three hours. Thankfully, the pmonitor tool allows us to precisely monitor the progress of many commands. Here’s an example of its application on MariaDB.
