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

Chapter 5: Resources, Data Sources, and Dependencies

by: Akhilesh Mishra Fri, 28 Nov 2025 15:42:59 +0530 Think of Terraform as a construction manager. Resources are the buildings you construct. Data sources are the surveys you conduct before building. Dependencies are the order in which construction must happen. You can’t build the roof before the walls, right? Resources: The Heart of Everything If Terraform were a programming language, resources would be the objects. They’re things you create, modify, and delete. Every piece of infrastructure —

Chapter 4: Terraform State and Providers

by: Akhilesh Mishra Fri, 28 Nov 2025 15:39:09 +0530 How does Terraform remember what it created? How does it connect to AWS or Azure? Two concepts answer these questions: State (Terraform’s memory) and Providers (Terraform’s translators). Without state and providers, Terraform would be useless. Let’s understand them. What is Terraform State? State is Terraform’s memory. After terraform apply, it stores what it created in terraform.tfstate. Run this example: resource "local_file" "example" { co

Chapter 3: Terraform Variables and Locals

by: Akhilesh Mishra Fri, 28 Nov 2025 15:35:51 +0530 Basic Variable Types Terraform has three basic types: string, number, and bool. variable "name" { type = string description = "User name" default = "World" } variable "counts" { type = number default = 5 } variable "enabled" { type = bool default = true } Use them: resource "local_file" "example" { content = "Hello, ${var.name}! Count: ${var.counts}, Enabled: ${var.enabled}" filename = "output.txt" } 🚧You cannot use reserved words like count

Chapter 1: Infrastructure as Code - Here We Go

by: Akhilesh Mishra Fri, 28 Nov 2025 15:33:10 +0530 If you go back two decades, everyone used those physical servers (produced by IBM, HP, and Cisco), which took weeks to setup correctly before we could run the applications on them. Then came the time of virtualization. Sharing computing resources across multiple OS installations using hypervisor-based virtualization technologies such as VMware became the new normal. It reduced the time to spin up a server to run your application but also incr

After Fitbit Killed it in 2016, Pebble Returns with 100% Open Source Software and Hardware

by: Sourav Rudra Fri, 28 Nov 2025 09:50:08 GMT Pebble, the e-paper smartwatch that first launched on Kickstarter in 2012, gained a cult-like following for its innovative approach to wearable tech. Sadly, Fitbit acquired and shut it down in 2016, taking with it the intellectual property (IP) of the brand. The IP eventually landed with Google after their Fitbit acquisition in 2021. Earlier this year, the original creator, Eric Migicovsky, relaunched Pebble through Core Devices LLC, a self-fun

Self-Hosting is Rising and Linux Users are Leading This Revolution

by: Theena Kumaragurunathan Fri, 28 Nov 2025 08:29:16 GMT In a previous column, I argued that self-hosting is resistance in an age where ownership is increasingly illusory. There is increasing evidence that self-hosting is becoming popular among a certain kind of user, say the typical readership of ItsFoss. There is a simple explanation for this shift: people want their data, dollars, and destiny back. Centralized platforms optimized for engagement and extraction are colliding with real-wor

KDE Plasma 6.8 to Drop X11 Support, Goes All-In on Wayland

by: Sourav Rudra Thu, 27 Nov 2025 17:00:46 GMT A growing number of Linux desktop environments (DEs) are moving towards Wayland, the modern display protocol designed to replace the aging X11 window system. X11 has been the foundation of Linux graphical interfaces for over three decades now, but it carries significant technical debt and security limitations that Wayland aims to address. Projects like Fedora, GNOME, and KDE have been leading the charge on this by being among the first ones to

Google Just Made Its Sleek New Font Open Source

by: Sourav Rudra Thu, 27 Nov 2025 14:13:02 GMT If you spend a lot of time on a computer, then fonts matter more than you think. A good one reduces eye strain and makes reading the contents of the screen easier. The right one can drastically improve your entire desktop experience. In my case, I like to use Inter on my Fedora-powered daily driver, and I don't really mess around with it. But everyone's different. Some like rounded fonts. Others want sharp, clean lines. Having options matters.

by: Abhishek Prakash Thu, 27 Nov 2025 10:33:18 GMT As Linux users, most of us prefer open-source software. But if you’ve been using Linux for a while, you know this truth too: in daily workflows, you may have to rely on proprietary software.

Open Source Never Dies: 11 of My Favorite Linux Apps That Refused to Stay Dead

by: Roland Taylor Wed, 26 Nov 2025 11:03:03 GMT One of the greatest things about open-source software is that anyone can pick up where a project left off and bring it back to life, whether it's to continue a legacy, or a spiritual successor that builds on a new foundation. In this article, I'll share some of the popular Linux apps that got new lives as "New/Next Generation" (-ng) versions of their former selves. 1. iotop-c iotop-c gives iotop a refreshed lookYou've heard of top and htop, bu

Backup and Restore Your Flatpak Apps & Settings Between Distro Switch and Reinstalls

by: Roland Taylor Tue, 25 Nov 2025 03:08:57 GMT Flatpak has pretty much become the de-facto standard for universal packages on the Linux desktop, with an increasing number of distros supporting the format in their default installs. Yet, even with how easy it is to install and update Linux apps with Flatpak, moving them to a new system can be tricky, especially if you’ve installed dozens over time. Sure, you could list and reinstall everything manually, but that’s tedious work, and easily pr
