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

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.

7 Privacy Wins You Can Get This Weekend (Linux-First)

by: Theena Kumaragurunathan Sun, 09 Nov 2025 03:44:40 GMT Privacy is a practice. I treat it like tidying my room. A little attention every weekend keeps the mess from becoming a monster. Here are seven wins you can stack in a day or two, all with free and open source tools. 1. Harden your browser Firefox is still the easiest place to start. Install uBlock Origin, turn on strict tracking protection, and only whitelist what you truly need. Add NoScript if you want to control which sites can r

Pentora Box: Pen-Test Practice Labs

by: Abhishek Prakash Sat, 08 Nov 2025 17:52:50 +0530 Learn by doing, not just reading or watching. Pen-testing can’t be mastered by watching videos or reading blogs alone. You need to get your hands dirty. Pentora Box turns each Linux Handbook tutorial into a self-try exercise. Every lab gives you a realistic, safe environment where you can explore reconnaissance, scanning, exploitation, and post-exploitation, step by step. How to use it?

A to Z Hands-on Guide to Building and Publishing an Open Source Project to CNCF

by: Sachin H R Fri, 07 Nov 2025 17:49:50 +0530 The idea for a practical guide to build an open source project and publishing it to CNCF came to me when I was working on KubeReport, an open source tool that automatically generates PDF/CSV deployment reports from your Kubernetes cluster. It is designed for DevOps teams, QA, and managers. It can auto-email reports, integrate with Jira, and track exactly what got deployed and when. I noticed that there were not clear enough documentation on how to

Explaining the Accessible Benefits of Using Semantic HTML Elements

by: Geoff Graham Thu, 06 Nov 2025 15:57:49 +0000 Here’s something you’ll spot in the wild: <div class="btn" role="button">Custom Button</div> This is one of those code smells that makes me stop in my tracks because we know there’s a semantic <button> element that we can use instead. There’s a whole other thing about conflating anchors (e.g., <a class="btn">) and buttons, but that’s not exactly what we’re talking about here, and we have a great guide on it. A s

Ownership of Digital Content Is an Illusion—Unless You Self‑Host

by: Theena Kumaragurunathan Thu, 06 Nov 2025 10:56:15 GMT The internet of the early 2000s—what I once called the revelatory internet—felt like an endless library with doors left ajar. Much of that material circulated illegally, yes. I am not advocating a return to unchecked piracy. But the current licensing frameworks are failing both artists and audiences, and it’s worth asking why—and what a better model could look like. Hands up if you weren’t surprised to see streaming services plateaui

Fixing Image Thumbnails Not Showing Up in GNOME Files on Fedora Linux

by: Abhishek Prakash Thu, 06 Nov 2025 07:12:58 GMT I recently upgraded to Fedora 43 and one thing I noticed was that image thumbnails were not showing up in the Nautilus files manager. Not just the recent file formats like webp or AVIF, it was not even showing up for classic image file formats like png and jpeg.

What is more concerning is the report that more than 50% of the internet traffic is by bots. Gone are the days when the Internet connected humans. Are we heading towards the death of the internet?

by: Chris Coyier Wed, 05 Nov 2025 23:15:47 +0000 Shaw and Chris are on the show to talk about the thinking and challenges behind upgrading these rather important bits of technology in our stack. We definitely think of React version upgrades and Next.js version upgrades as different things. Sometimes they are prerequisites. The Next.js ones are a bit more important as 1) the docs for the most recent version tend to be the best and 2) it involves server side code which is important for security r

YouTube Goes Bonkers, Removes Windows 11 Bypass Tutorials, Claims 'Risk of Physical Harm'

by: Sourav Rudra Wed, 05 Nov 2025 04:29:31 GMT We are no strangers to Big Tech platforms occasionally reprimanding us for posting Linux and homelab content. YouTube and Facebook have done it. The pattern is familiar. Content gets flagged or removed. Platforms offer little explanation. And when that happens, there is rarely any recourse for creators. Now, a popular tech YouTuber, CyberCPU Tech, has faced the same treatment. This time, their entire channel was at risk. YouTube's High-Handedne

What is a Media Server Software? Why You Should Care About it?

by: Abhishek Prakash Tue, 04 Nov 2025 10:48:42 GMT Media servers have exploded in popularity over the past few years. A decade ago, they were tools for a small population of tech enthusiasts. But with the rise of Raspberry Pi-like devices, rising cost of streaming services and growing awareness around data ownership, interest in media server software has surged dramatically. In this article, I'll explain what a media server is, what benefits it provides, and whether it's worth the effort to

We'll be testing a deliberately vulnerable practice site, so you can follow along safely and see exactly how it

Chris’ Corner: AI Browsers

by: Chris Coyier Mon, 03 Nov 2025 18:00:42 +0000 We’re definitely in an era where “AI Browsers” have become a whole category. ChatGPT Atlas is the latest drop. Like so many others so far, it’s got a built-in sidebar for AI chat (whoop-de-do). The “agentic” mode is much more interesting, weird sparkle overlay and all. You can tell it to do something out on the web and it gives it the old college try. Simon Willison isn’t terribly impressed: “it was like watching a first-time computer user p

The “Most Hated” CSS Feature: tan()

by: Juan Diego Rodríguez Mon, 03 Nov 2025 16:03:08 +0000 Last time, we discussed that, sadly, according to the State of CSS 2025 survey, trigonometric functions are deemed the “Most Hated” CSS feature. That shocked me. I may have even been a little offended, being a math nerd and all. So, I wrote an article that tried to showcase several uses specifically for the cos() and sin() functions. Today, I want poke at another one: the tangent function, tan(). CSS Trigonometric Function

Like It Or Not, Rust Is Coming To Debian's APT Package Manager

by: Sourav Rudra Mon, 03 Nov 2025 15:08:48 GMT Rust has been making waves in the information technology space. Its memory safety guarantees and compile-time error checking offer clear advantages over C and C++. The language eliminates entire classes of bugs. Buffer overflows, null pointer dereferences, and data races can't happen in safe Rust code. But not everyone is sold. Critics point to the steep learning curve and unnecessary complexity of certain aspects of it. Despite criticism, majo
