  • Encryption at Rest in MariaDB – Linux Hint

    Encryption-at-rest prevents an attacker from accessing encrypted data stored on the disk even if he has access to the system. The open-source databases MySQL and MariaDB now support encryption-at-rest feature that meets the demands of new EU data protection legislation. MySQL encryption at rest is slightly different from MariaDB as MySQL only provides encryption for InnoDB tables. Whereas MariaDB also provides an option to encrypt files such as redo logs, slow logs, audit logs, error logs, etc. However, both can’t encrypt data on a RAM and protect it from a malicious root. In this article, we will learn to configure database-level encryption for MariaDB.

  • How To Find Out Which Groups A User Belongs To In Linux

    A Linux group is a collection of one or more users with identical permission requirements on files and directories. An user can be a member of more than group at a time. In Linux, each group information is stored in the "/etc/group" file. In this tutorial, we will see all the possible ways to easily find out which groups a user belongs to in Linux and Unix-like operating systems. Finding out the groups to which a user account belongs will be helpful in many occasions. For instance, the other day I was installing Dropbox on my Ubuntu server. When configuring Dropbox, I had to enter my current user name and the group name. You could also be in a situation where you need to identify the groups a user belongs to. If so, use any one of the following methods to know what group a user is in.

  • How do I Completely Remove a Package in Linux Mint 20? – Linux Hint

    The task of removing an installed package from any operating system can surely be a hassle if handled carelessly.

However, such a complete removal cannot be achieved without taking certain measures. That is why today’s article will be focused on the method of completely removing a package in Linux. Note: The method that we have attempted and shared with you in this article has been performed on a Linux Mint 20 system. However, the very same steps can also be performed on Ubuntu 20.04 and Debian 10.

  • How to Install Spotify in Fedora Linux – Linux Hint

  • How to Delete Files Older Than Specified Days in Linux

    As you might already know, we use the rm command in Linux to delete files and folders. The filenames to be deleted have to be passed as arguments to rm. However, rm does not offer other options by itself, like deleting files based on timestamps. That’s the reason, we use the find command in Linux, which is used to search for files and folders based on different parameters. It is a complex command which can be used to search with parameters like the filename, size, type of file, etc. There is an option in the find command to search for files based on how old they are and today we will see how to use find and rm together to delete files older than the specified number of days.

  • How Can I Sudo Another User Without A Password? – Linux Hint

    In Linux platforms, a sudo user is a tool that implies “superuser do” to run various systems’ commands. A sudo user is typically a root user or any other user who has some privileges. To delegate important tasks like server rebooting or restarting the Apache server, or even to create a backup using the sudo command, you can use the sudo without having to enter the password again and again. By default, sudo user needs to provide some user authentication. At times, user requirements are to run a command with these root privileges, but they do not desire to type a password multiple times, especially while scripting. This is easily doable in Linux systems. In this article, we will check the method to sudo another user without entering their password.

Yes, if you want to launch Ubuntu Linux command line server VMs instantly on Windows, Linux and macOS then cross-platform Multipass is one of the good options to consider.

  • How to use the sipcalc Linux command line tool | Enable Sysadmin

    The only network numbers I can keep in my head are now and always have been a Class C network with a 24-bit netmask, such as 192.168.1.0/24. I know there are 254 usable host addresses available with a broadcast address of 192.168.1.255, a gateway/router address of 192.168.1.1 or 192.168.1.254 (depending on who's running the network), and a human-readable netmask of 255.255.255.0. That's my standard network. After all, 254 hosts are enough for any subnet, right? Wrong. A few years back, I had to step outside of my standard 254 hosts per subnet scenario when I decided to use a 22-bit netmask (255.255.252.0) to get a 1022 usable address space. I knew little about this address space, and it was frustrating to try to search for the simple information that I needed without scrolling through forums with all the idle chatter and off-topic rhetoric. I guess some people just need a space in which to air their grievances about everything. I digress.

GhostBSD Review: Simple and Lightweight

Because there are so many different options out there for your free and open-source operating system, it can be hard to figure out what the best option is for you. Sifting between Linux distros is difficult – Debian and its derivatives, Ubuntu and its derivatives, Fedora, Arch, openSUSE, the list goes on. However, what if the best choice for you isn’t actually technically Linux? Here we review GhostBSD, a FreeBSD-based Unix OS designed for a simple desktop experience, to see if it’s the right fit for you. [...] The applications that are installed are all necessary. It’s exactly what you might expect to find in your typical lean open-source desktop OS configuration, with no frills and just the essential applications. There is not much to remark on with the user experience – it is a very simple and friendly version of the MATE desktop that’s designed to be light on system resources and simple to use. Overall, I think there is no way you could go wrong. Read more

Now, we are sharing with you all the predictions we received, from quite a few places across the world as you can see from the below map. The Linux Gaming Community knows no frontiers.

  • Team Cherry upgrade the excellent Hollow Knight with Vulkan for Linux | GamingOnLinux

    Team Cherry have given their excellent action-platformer metroidvania Hollow Knight a bit of an upgrade, which you can test out on Steam in a fresh Beta test. Not played it before? You're missing out. Hollow Knight is a classically styled 2D action adventure across a vast interconnected world. Explore twisting caverns, ancient cities and deadly wastes; battle tainted creatures and befriend bizarre bugs; and solve ancient mysteries at the kingdom's heart.

  • OpenLoco is a free and open source re-implementation of Chris Sawyer's Locomotion | GamingOnLinux

    Just like there's the awesome OpenTTD for fans of Transport Tycoon Deluxe, there's also OpenLoco for players who want to play through the classic Locomotion. Not a project we've covered here before it seems, so we're making that right today. Originally released back in 2004, it's actually a spiritual successor to Transport Tycoon but it was not as loved due to various problems with the original release. Perhaps though it can have a new life thanks to OpenLoco.

  • VRWorkout is a free and open source VR fitness rhythm game

    Well, that's certainly one way to get a bit more exercise in. Whatever helps right? No judgement here, I could probably do with a little more myself… It's built with the free and open source game engine Godot Engine, so not only is the source code open for the game itself it's properly open for anyone to put it together from the source and will remain so. Speaking about VRWorkout to us on Twitter, the developer mentioned they actually do develop for it on Linux but they use a Quest headset not supported on Linux so they have to work with that on Windows. Perhaps though, in time, Monado might break down that barrier.

  • Free and open source voxel game engine Minetest 5.4 is out, makes mods easier for users | GamingOnLinux

    Minetest, the Minecraft-like voxel game engine (and a basic game that comes with it) has a big new release out with Minetest 5.4.0 and it's worth trying again. As we covered before during the Release Candidate stage, one of the big features for users in this release is vastly easier modding with both small mod packs and entire games. Minetest had a way to browse and download them all directly in the game for a while, but now it will also actually download all the dependencies mods need - making it vastly easier to get what you want and then into a game. No more downloading one mod, then finding all the individual bits it needs.
