  • 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.

Small Image Tools that Pack a Real Punch

The spotlight usually focuses on the heavyweight Linux graphics tools such as GIMP, Shotwell, digiKam, Inkscape, and Krita. However, there are many other open source graphics tools that merit attention. Linux offers a vast collection of open source small utilities that perform functions ranging from the obvious to the bizarre. It is the quality and selection of these tools that help Linux stand out as a productive environment. A good utility cooperates with other applications, integrating seamlessly. Although command-line tools are very useful for updating, configuring, and repairing a system, their benefits are not only confined to system administration. The majority of the applications featured in this article are command-line tools. They are very light on system resources, fast and efficient, don’t rely on a windowing system, and are great for integrating with other applications and scripting. The term lightweight is a label attached to computer software which is relatively simpler or faster than its counterparts. Feature bloat is endemic in software especially commercial software. Often, the easiest way to persuade users to upgrade to the latest version is to add new spangly features. This happens with open source software (to a lesser degree), and open source graphics software is not immune to feature bloat. Well, there is no feature bloat here! To provide an insight into the quality of software that is available, we have compiled a list of small image tools that are incredibly useful. Read more

Hands-On with Raspup on Raspberry Pi 4: Puppy Linux for Tinkerers

If you never heard of Raspup before, let me tell you that it’s a Debian-based GNU/Linux distribution built from the Woof-CE build system that was originally developed by Barry Kauler, the creator of Puppy Linux, and binary compatible with Raspbian (the official Raspberry Pi OS). As such, Raspup is a Puppy Linux port for Raspberry Pi. Raspup was created by Michael Amadio and it’s designed to run on ARMv7l hardware, specifically on the Raspberry Pi Zero, Raspberry Pi 1, Raspberry Pi 2, Raspberry Pi 3, Raspberry Pi 3+, and Raspberry Pi 4 single-board computers (SBCs).
