  • 4 Ways to Check MySQL or MariaDB version on Linux - Linux Shout

    This tutorial will let you know the key commands or ways we can use to check the MySQL or MariaDB Database server version running on Linux operating systems such as Debian, Ubuntu, CentOS, Rocky Linux, AlmaLinux, and more.

    If you have already done the installation of MySQL or MariaDB server on your Linux. Then now you probably have a question about how to check which version you are actually using?

    Also, MySQL is one of the popular and most common database servers using around the world to store data. However, don’t be confused between MySQL and MariaDB because the latter one is the fork of MySQL, nothing more than that. Hence, the commands used for Oracle MySQL will also be applicable for MariaDB.

  • How to ZIP a folder in Ubuntu

    Sometimes, you want to share a directory or folder that contains a bundle of files with someone. In this situation, compressing the folder in a .zip file format is a good approach. Zip is the commonly used and popular archive file format in many operating systems for file compression that provides lossless data compression features.

    The zip file behaves as a container that is composed of more compressed files or folders. There are more file formats such as .tar extension, also common practice to use for Linux systems, but still zipping folders using .zip extension is ubiquitous and a perfect choice.

    Using Zip file format for file compression takes less disk space and saves the network bandwidth while you transfer a file from one machine to another system. Zipped file format can be transferred more quickly as compared to uncompressed files. These compressed zip folders can easily be extracted using supportive utilities in Linux, macOS, and Windows operating systems.

    You will learn in this guide how to zip a folder in Ubuntu Linux operating system. We will explain two methods for zipping a folder; one method is zip a folder using command-line and the other using the Gnome graphical interface environment. All steps we will cover in this article have been implemented on Ubuntu 20.04 LTS focal fossa distribution.

    This is a case where the time from when I took it to when it was resolved happened to be about half an hour. Being half an hour late might not mean a lot to some people, but computer systems are much more sensitive to time and need it to be accurate and synchronized. That’s why it’s crucial to have a solid NTP (Network Time Protocol) infrastructure. This case shows how important attention to detail can be when troubleshooting a system.

  • Looking at the outlying data points

    The solution was great: they came up with something that looked like a server for airflow purposes, but which didn't actually do anything. It was basically two very big paperboard pizza boxes side by side. They would then slip that into the rack right below the last server, or any time they pulled one from somewhere higher in the stack. This would keep the airflow doing its thing happily for whatever was right above it.

    This rolled out and my hot spots disappeared. Fantastic!
