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).

Graph RAG: Elevating AI with Dynamic Knowledge Graphs

by: Nitij Taneja Thu, 13 Nov 2025 09:50:29 GMT Introduction In the rapidly evolving landscape of Artificial Intelligence, Retrieval-Augmented Generation (RAG) has emerged as a pivotal technique for enhancing the factual accuracy and relevance of Large Language Models (LLMs). By enabling LLMs to retrieve information from external knowledge bases before generating responses, RAG mitigates common issues such as hallucination and outdated information. However, traditional RAG approaches often rel

Ubuntu's Rust Transition Hits Another Bump as sudo-rs Security Vulnerabilities Show Up

by: Sourav Rudra Wed, 12 Nov 2025 13:29:24 GMT Ubuntu's move to Rust-based system utilities has hit some bumps. Earlier, a bug in the Rust-based date command broke automatic updates. The command returned current time instead of file modification timestamps, causing Ubuntu 25.10 systems to stop automatically checking for software updates. That issue was quickly fixed, but now, two security vulnerabilities have been found in sudo-rs. Better Now than Later The first vulnerability involves pass

The Self-Hosting Starter Pack: 5 Simple Tools I Recommend To Get Started With Your Homelab

by: Theena Kumaragurunathan Wed, 12 Nov 2025 07:21:41 GMT In my last column, Ownership is an illusion, unless you self-host, I encouraged readers to go down the self-hosting path. My thesis was simple: ownership of digital assets (movies, music, games, books, software) is an illusion, and that the only way to move away from this make-believe was to embrace self-hosting. For people like me, non-programmer types, this is easier said than done: Free and Open Source (FOSS) can seem intimidatin

Common Networking Issues Every DevOps Engineer Encounters

by: Umair Khurshid Tue, 11 Nov 2025 20:03:47 +0530 Networking problems rarely announce themselves clearly. A deployment fails, a pod cannot reach its database, or a service responds intermittently. The logs look clean, yet something feels wrong. Most engineers eventually learn one painful truth: when everything else seems fine, it is usually the network. From misrouted traffic to invisible firewalls, let me walk you through the most frequent networking issues that DevOps engineers encounter in

Chris’ Corner: Browser Feature Testing

by: Chris Coyier Mon, 10 Nov 2025 18:00:39 +0000 It’s interesting to me to think about during a lot of the web’s evolution, there were many different browser engines (more than there are now) and they mostly just agreed-on-paper to do the same stuff. We focus on how different things could be cross-browser back then, which is true, but mostly it all worked pretty well. A miracle, really, considering how unbelievably complicated browsers are. Then we got standards and specifications and that

How Developers Use Proxies to Test Geo Targeted APIs?

Every country, every city, and every mobile network can respond differently and will require distinct adjustments. When pricing endpoints contain location-based compliance features and payment options, testing them will require more than one physical location.

Most people and organizations rely on these formats for daily document work. This creates a predatory situation where vendor lock-in is the norm and compatibility issues are taken as a omen that moving away from Microsoft Office is a bad idea.

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

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.
