How To Install Docker on Linux Mint 20
In this tutorial, we will show you how to install Docker on Linux Mint 20. For those of you who didn’t know, Docker is an open-source project that automates the deployment of the application inside the software container. The container allows the developer to package up all project resources such as libraries, dependencies, assets, etc. Docker is written in a Go Programming language and is developed by Dot cloud. It is basically a container engine that uses the Linux Kernel features like namespaces and control groups to create containers on top of an operating system and automates the application deployment on the container.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step by step installation of Docker on a Linux Mint 20 (Ulyana).

How to Secure Email Server Against Hacking with VPN (CentOS/RHEL)
In this tutorial, I’m going to share with you my tips and tricks to secure CentOS/RHEL email servers against hacking with a self-hosted VPN server. Many spammers are trying to hack into other people’s email servers. If successful, they would use the hacked email server to send large volumes of spam or steal valuable data. Why do we use a self-hosted VPN server? Because it allows you to enable whitelisting, so only trusted users connected to the VPN server can access your mail server.

Fixed compile of libvdpau-va-gl in OE
I posted yesterday about the problem in OpenEmbedded when the compile of a package requires execution of a binary:
https://bkhome.org/news/202101/fixed-compile-of-samba-without-krb5-in-oe.html
This problem does not occur if the build-architecture and target-architectures are the same. The problem occurs with a cross-compile.
Today I had the same problem, with package 'libvdpau-va-gl'. I had previously compiled this in OE, but now the build-arch is x86_64 and the target-arch is aarch64.
