Why Every SysAdmin Should Understand ISO/IEC 27001:2022

In today’s digital landscape, the role of a System Administrator (SysAdmin) extends far beyond server uptime and software updates. With cyber threats evolving daily, understanding key information security standards like ISO/IEC 27001:2022 is no longer optional, it’s essential. This international standard provides a robust framework for establishing, implementing, maintaining, and continuously improving an Information Security Management System (ISMS).

Harden and Secure Linux Servers by Level (1 - 6)

Securing a Linux server is an ongoing challenge. Every day, bad actors attempt to penetrate systems worldwide, using VPNs, IP spoofing, and other evasion tactics to obscure their origins. The source of an attack is often the least of your concerns, what matters most is implementing strong security measures to deter threats and protect your infrastructure. Hardening your servers not only makes them more resilient but also forces attackers to either move on or, ideally, abandon their efforts altog

FOSS Weekly #25.35: New Gerhwin DE, grep Command, Nitro init system, KDE Customization and More Linux Stuff

by: Abhishek Prakash Thu, 28 Aug 2025 05:50:35 GMT It's FOSS Community Forum is now open for free registration. Earlier, it was tied up with It's FOSS membership and allowed a single click login with It's FOSS. Going back to the old roots is more due to technical limitations. I share the details in the forum post, if you are interested in learning more about it. I was also expecting Mint 22.2 to release this week but it is not out yet. I'll keep you posted when it releases. 💬 Let's see wha

A Radio Button Shopping Cart Trick

by: Preethi Wed, 27 Aug 2025 14:18:12 +0000 Editor’s note: This is a really clever idea that Preethi shared, but you will also see that it comes with accessibility drawbacks because it uses duplicated interactive elements. There are other ways to approach this sort of thing, as Preethi mentions, and we’ll look at one of them in a future article. Two large pizzas for yourself, or twelve small ones for the kids party — everyone’s gone through the process of adding items to an online cart. Gro

Installing Fedora Linux in the Simplest Possible Way

It is cutting edge, backed by Red Hat, features newer features and has a wide community support. If you have chosen to use it as your main desktop operating system, let me show you the steps for installing Fedora. 🚧Please note that this will erase any other operating system and all the data on your computer and install a fresh Fedora Linux on it.

Using Nightlight in Hyprland

by: Sreenath Tue, 26 Aug 2025 12:25:20 GMT I presume that you are no stranger to the nightlight feature. It filters blue light from your screen and shifts colors to warmer, orange tones during evening hours, reducing eye strain while using computers at night. From KDE to Cinnamon, most Linux desktop environments offer this as a bulit-in feature. Look at GNOME Nightlight feature; it is available right from the quick toggle buttons. GNOME NightlightDon't get your hopes high if you are using

Check Logs from Previous Boot With Journalctl

by: Abhishek Prakash Tue, 26 Aug 2025 13:26:28 +0530 Need to troubleshoot boot issues with Linux or check what happened during your last system startup? Linux keeps detailed records of every boot process, and knowing how to access them can save you hours of debugging time. If your Linux system uses systemd, you can use the journalctl command to filter the logs to only show entries since the last boot (current boot): journalctl -b You can widen your search by including logs from previous boots:

Getting Creative With Images in Long-Form Content

by: Andy Clarke Mon, 25 Aug 2025 17:16:35 +0000 When you picture placing images in long-form content — like articles, case studies, or reports — the standard approach is inline rectangles, breaking up blocks of text. Functional? Sure. Inspiring? Hardly. Why do so many long-form articles feel visually flat? Why do images so often seem bolted on, rather than part of the story? And how does that affect engagement, comprehension, or tone? Images in long-form content can (and often should) d

Chris’ Corner: Pretty Palettes

by: Chris Coyier Mon, 25 Aug 2025 16:17:42 +0000 I’m not terribly good at picking a good color palette out of thin air. My go-to is a dark look with bright colored accents, but I’m wildly envious whenever I see a beautiful website with great looking colors that are very far away from what I could pull off. Sometimes, a little inspiration can go a long way. Here’s some! Color Lisa Flexoki Mildliner Reference Kind of Rebeccapurple The story of how

Rethinking DevOps

by: Avimanyu Bandyopadhyay Mon, 25 Aug 2025 12:50:39 +0530 Ever since I started working with diverse web-apps at Linux Handbook and High On Cloud, the DevOps term has grabbed my attention many a time since that is something we specifically cover at Linux Handbook. We've covered tutorials on many tools related to DevOps but we've never really tried to explore the actual concept in depth. Since Linux Handbook is dedicated to Linux Servers, we also need to explore their important role in the De

Best Non-Violent Games Available on Steam for Linux Users

by: Sourav Rudra Sun, 24 Aug 2025 13:53:49 GMT Not everyone wants to spend their evening punching NPCs in the face or mowing down hordes of enemies after a long day. Sometimes you just want to chill, explore, solve puzzles, or build something cool. For me personally, Euro Truck Simulator 2 hits that sweet spot perfectly. There's something incredibly therapeutic about cruising down European highways, listening to tunes from the likes of AURORA, Tame Impala, and Glass Animals. Whether you're

Getting Started With Nano Editor

by: Abhishek Prakash Fri, 22 Aug 2025 20:30:23 +0530 Nano is perhaps one of the simplest terminal-based text editor. While it is still depended on keyboard, the shortcuts are simpler here when compared to Vim and Emacs. Nano also displays appropriate shortcuts on the bottom all the time, making it even easier to use. You don't need to remember all the shortcuts. Remember that in the keyboard shortcut suggestions, ^ means control and M means Alt. So, if you see: ^G: You press both Ctrl and G ke

3D Layered Text: Interactivity and Dynamism

by: Amit Sheen Fri, 22 Aug 2025 13:14:31 +0000 In the previous two chapters, we built a layered 3D text effect, added depth and color, and then brought it to life with motion. We explored static structure, animated variations, and even some clever decoration tricks. But everything so far has been hard-coded. This time, we’re going dynamic. In this final chapter, we’re stepping into the world of interactivity by adding JavaScript into the mix. We’ll start by generating the layers program

Use Proxmox for Virtual Machines

by: Doron Beit-Halahmi Fri, 22 Aug 2025 14:55:01 +0530 Proxmox is a type-1 hypervisor that you install on a physical server. And then you use it to create numerous virtual machines and containers, manage them, create clusters with them, and what not. If you would like to learn virtualization or you would like to create a setup that involves using dedicated hardware for various Linux servers, Proxmox is the force to reckon with. If you are getting started with Proxmox, you are at the right plac

We live in an era where dissent is crushed and corporations treat user data like chips on a poker table. Your browsing habits, location data, and online communications have become valuable commodities to be traded without your consent.
