How To Install Graylog on Ubuntu 22.04 LTS - idroot
In this tutorial, we will show you how to install Graylog on Ubuntu 22.04 LTS. For those of you who didn’t know, Graylog is a free and open-source log monitoring application that can capture, store, and analyze gigabytes of machine data in real time. It is designed for modern log analytics that allows users to quickly and easily find meaning in data and take action faster.
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 the step-by-step installation of Graylog log management software on Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.

How Wine works 101
Wine is a compatibility layer capable of running Windows applications on several POSIX-compliant operating systems, such as Linux, macOS, & BSD (https://www.winehq.org).
If you have been using Linux for some time now, chances are you’ve used Wine at some point. Maybe to run that one very important Windows program that doesn’t have a Linux version or maybe to play World of Warcraft or some other game. Fun fact, Valve’s Steam Deck uses a Wine-based solution to run games (called Proton).
In the last year I’ve spent quite some time working on a debugger capable of debugging both the Wine layer and the Windows application running with it. It was very interesting to learn about the Wine internals – I’ve used Wine many times before, but never knew how it worked. If you ever wondered how it’s possible to take a Windows executable and just run it on Linux without any modifications – welcome to this article!

How to Use Log2Ram on Linux to Save Wear and Tear on Your Disks
Continuous logging and read/write operations can harm your storage disks. Install Log2Ram on your Linux desktop to improve the lifespan of your disks.
Almost everything your Linux machine does is written to disk as part of a log file. Even when you're away from the keyboard or sleeping, dozens of logs are constantly updated, ready for you to search through and diagnose problems or optimize processes.
This constant writing can have an impact on the lifespan of your storage medium, and cause it to wear out sooner than it otherwise would. Save your disks and your wallet by using the Log2Ram app to minimize disk writing!
