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

The “Most Hated” CSS Feature: asin(), acos(), atan() and atan2()

by: Juan Diego Rodríguez Mon, 17 Nov 2025 14:47:54 +0000 This is a series! It all started a couple of articles ago, when we found out that, according to the State of CSS 2025 survey, trigonometric functions were the “Most Hated” CSS feature. I’ve been trying to change that perspective, so I showcased several uses for trigonometric functions in CSS: one for sin() and cos() and another on tan(). However, that’s only half of what trigonometric functions can do. So today, we’ll poke at

Clean Up Your GNOME Panel With This New Extension

by: Sourav Rudra Mon, 17 Nov 2025 12:49:10 GMT I rely heavily on GNOME extensions for my daily workflow. From Dash to Dock for quick app launching to Tiling Shell to effortlessly manage app windows while working. These basically turn the vanilla GNOME experience into something that truly fits my needs. While browsing through the latest This Week in GNOME post, I stumbled upon something interesting. A developer announced Veil, describing it as a cleaner and more modern way than Hide Items to

Snapchat Opens Valdi Framework to Developers After 8 Years of Internal Use

by: Sourav Rudra Mon, 17 Nov 2025 09:30:47 GMT Snap Inc., the company behind Snapchat, has open-sourced Valdi, a cross-platform mobile UI framework. The social media company typically keeps its technology in-house, but this marks a surprising move into open source territory. While there was no dedicated announcement for this on their news portal, The New Stack were the first ones to report this; I am assuming they received a press release for this. Anyhow, let's dive into this interesting d

Better Than Original? 14 Rust-based Alternative CLI Tools to Classic Linux Commands

by: Neville Ondara Sun, 16 Nov 2025 00:47:33 GMT If you’re like me, you probably grew up with the classic Linux command-line tools such as ls, cat, du. These commands have carried me through countless scripts and late-night debugging sessions. Here's the thing. While these tools do their job, they can be plain looking and difficult to use for certain tasks. Take the du command for example. It shows the disk usage on the system but use it without any option, and it is a mess. Terminals tod

Quiet UI Came and Went, Quiet as a Mouse

by: Ryan Trimble Fri, 14 Nov 2025 15:32:50 +0000 A few weeks ago, Quiet UI made the rounds when it was released as an open source user interface library, built with JavaScript web components. I had the opportunity to check out the documentation and it seemed like a solid library. I’m always super excited to see more options for web components out in the wild. Unfortunately, before we even had a chance to cover it here at CSS-Tricks, Quiet UI has disappeared. When visiting the Quiet UI websi

Mozilla Unveils Plans for New 'AI Window' Browsing Mode in Firefox, Opens Signups

by: Sourav Rudra Fri, 14 Nov 2025 13:37:14 GMT Firefox has been pushing AI features for a while now. Over the past year, they've added AI chatbots in the sidebar, automatic alt text generation, and AI-enhanced tab grouping. It is basically their way of keeping up with Chrome and Edge, both of which have gone all-in on AI. Of course not everyone is thrilled about AI creeping into their web browsers, and Mozilla (the ones behind Firefox) seems to understand that. Every AI feature in Firefox i

LHB Linux Digest #25.35: Trap, Network Troubleshooting Tips, Self-host Server Management and More

by: Abhishek Prakash Fri, 14 Nov 2025 17:08:50 +0530 Feels like 2025 is ending sooner than expected. I know that's not the case but it just feels like that 😄 On that note, we plan to publish at least two more courses for you before the year ends. They are likely to be on Terraform and Kubernetes. I am also planning a microcourse on 'automated backups with cron and rsync'. These classic Linux tools are always reliable. And in the meantime, we are also working on expanding our collection of hand

FFmpeg Calls Google's AI Bug Reports "CVE Slop"

by: Sourav Rudra Fri, 14 Nov 2025 01:53:05 GMT FFmpeg maintainers have publicly criticized Google after its AI tool reported a security bug in code for a 1995 video game. The maintainers called the finding "CVE slop" and questioned whether trillion-dollar corporations should use AI to find security issues in volunteer code without providing fixes. Unchecked Automation is Not an Answer So what happened is, Google's AI agent Big Sleep found a bug in FFmpeg's code for decoding LucasArts Smush

The Range Syntax Has Come to Container Style Queries and if()

by: Daniel Schwarz Thu, 13 Nov 2025 15:00:20 +0000 The range syntax isn’t a new thing. We‘re already able to use it with media queries to query viewport dimensions and resolutions, as well as container size queries to query container dimensions. Being able to use it with container style queries — which we can do starting with Chrome 142 — means that we can compare literal numeric values as well as numeric values tokenized by custom properties or the attr() function. In addition, this featur

Why I Stopped Hating Systemd

by: Umair Khurshid Thu, 13 Nov 2025 18:02:00 +0530 Every few years, the Linux world finds something to fight about. Sometimes it is about package managers, sometimes about text editors, but nothing in recent memory split the community quite like systemd. What began as an init replacement quietly grew into a full-blown identity crisis for Linux itself, complete with technical manifestos, emotional arguments, and more mailing list drama than I ever thought possible. I did not plan to take a side

by: Sourav Rudra Thu, 13 Nov 2025 12:13:58 GMT Nitrux is a Debian-based Linux distribution that has always stood out for its bold design choices. It even made our list of the most beautiful Linux distributions. Earlier this year, the project made a significant announcement.

by: Sourav Rudra Wed, 12 Nov 2025 15:11:51 GMT The Linux ecosystem is facing increasing pressure from threat actors, who are getting more clever day-by-day, threatening critical infrastructure worldwide. Servers powering essential services, industrial control systems, and enterprise networks all rely on Linux, and these attackers know it. What was once considered a relatively safe ecosystem is now a lucrative target. 🥲 This brings us to Kaspersky, the Russian cybersecurity firm with a reput

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

You Can Play Classic D3D7 Games on Linux With This New Project, But Don’t Expect Perfection

by: Sourav Rudra Tue, 11 Nov 2025 17:23:36 GMT D7VK is a new Vulkan-based translation layer for Direct3D 7. It relies on DXVK’s Direct3D 9 backend and works with Wine on Linux. The project is open source and actively maintained. The developer behind it is WinterSnowfall, who has also worked on D8VK between 2023 and 2024. That project has since been merged into the larger DXVK project that's extensively used by Linux users. You have to understand that D7VK is not meant to run every Direct3D

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

Tired of Help Scout Pulling the Rug from Under You? Try This Free, Open Source Alternative

by: Sourav Rudra Tue, 11 Nov 2025 14:22:16 GMT Having a reliable help desk solution is a must for any consumer-facing business in today's digital age. Whether you handle customer emails, support tickets, or live chat, a good help desk system keeps your communication organized and your customers happy. Sadly, many companies take advantage of this need. They push users into walled gardens where access to basic features can change on a whim and key tools get locked behind paywalls. Help Scout'

What a Shame! FlatHub is Ranking on Google for Po*nHub Downloads

by: Abhishek Prakash Tue, 11 Nov 2025 11:07:18 GMT Imagine that one of the most prestigious open source software websites starts showing up in top results for "pornhub downloader". This is actually happening with Flathub, the official web-based app store for Flatpak packages. Here's a demo I made while risking to spoil my relationship with Google:
