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. 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). For SysAdmins, mastering ISO/IEC 27001 isn’t

Masonry: Watching a CSS Feature Evolve

by: Saleh Mubashar Mon, 13 Oct 2025 14:31:35 +0000 You’ve probably heard the buzz about CSS Masonry. You might even be current on the ongoing debate about how it should be built, with two big proposals on the table, one from the Chrome team and one from the WebKit team. The two competing proposals are interesting in their own right. Chrome posted about its implementation a while back, and WebKit followed it up with a detailed post stating their position (which evolved out of a third proposa

The Affordable Pironman Alternative Mini PC Case for Raspberry Pi 5

by: Abhishek Prakash Mon, 13 Oct 2025 07:48:52 GMT SunFounder's Pironman cases for Raspberry Pi are a huge hit. This bestselling device converts the naked Raspberry Pi board into a miniature tower PC. The RGB lighting, OLED display and glass casing make it look cool. Full HDMI ports, NVMe ports and active-passive cooling options enhance the functionality of the Pi 5. This great gadget is too expensive for some people to buy at $76 for the Pironman and $95 for the dual-NVMe NVMe Pironman Max

I Switched From Ollama And LM Studio To llama.cpp And Absolutely Loving It

by: Bhuwan Mishra Sat, 11 Oct 2025 02:26:37 GMT My interest in running AI models locally started as a side project with part curiosity and part irritation with cloud limits. There’s something satisfying about running everything on your own box. No API quotas, no censorship, no signups. That’s what pulled me toward local inference. My struggle with running local AI models My setup, being an AMD GPU on Windows, turned out to be the worst combination for most local AI stacks. The majority of A

We Completely Missed width/height: stretch

by: Daniel Schwarz Fri, 10 Oct 2025 14:03:52 +0000 The stretch keyword, which you can use with width and height (as well as min-width, max-width, min-height, and max-height, of course), was shipped in Chromium web browsers back in June 2025. But the value is actually a unification of the non-standard -webkit-fill-available and -moz-available values, the latter of which has been available to use in Firefox since 2008. The issue was that, before the @supports at-rule, there was no nice wa

412: 2.0 Embedded Pens

by: Chris Coyier Thu, 09 Oct 2025 15:45:43 +0000 Or just “Embeds” as we more frequently refer to them as. Stephen and Chris talk about the fairly meaty project which was re-writing our Embeds for a CodePen 2.0 world. No longer can we assume Pens are just one HTML, CSS, and JavaScript “file”, so they needed a bit of a redesign, but doing as little as possible so that existing Embed Themes still work. This was plenty tricky as it was a re-write from Rails to Next.js, with everything needing to be

The thing about contrast-color

by: Geoff Graham Wed, 08 Oct 2025 14:52:58 +0000 One of our favorites, Andy Clarke, on the one thing keeping the CSS contrast-color() function from true glory: Word. White and black are two very safe colors to create contrast with another color value. But the amount of contrast between a solid white/black and any other color, while offering the most contrast, may not be the best contrast ratio overall. This was true when added a dark color scheme to my personal website. The cont

Getting Creative With shape-outside

by: Andy Clarke Mon, 06 Oct 2025 15:45:40 +0000 Last time, I asked, “Why do so many long-form articles feel visually flat?” I explained that: Then, I touched on the expressive possibilities of CSS Shapes and how, by using shape-outside, you can wrap text around an image’s alpha channel to add energy to a design and keep it feeling lively. There are so many creative opportunities for using shape-outside that I’m surprised I see it used so rarely. So, how can you use it to add persona

Chris’ Corner: Discontent

by: Chris Coyier Mon, 06 Oct 2025 15:16:00 +0000 Nothing is above a little healthy criticism. Here’s Den Odell’s article We Keep Reinventing CSS, but Styling Was Never the Problem. If I can critique the critique, it makes some good and astute points, but pitting CSS evolution as the enemy up front doesn’t sit right. CSS itself, in my opinion, is doing great. It’s not the job of CSS to chase trends or bend toward fickle developer tooling trends. To be fair, Den also says it’s not re

Can't Recall the Syntax? Try These WYSIWYG Markdown Editors on Linux

by: Community Mon, 06 Oct 2025 15:05:57 GMT From GitHub repositories to technical documentation, Markdown is an extremely popular lightweight markup language. Basically, markdown files are plain text, but they follow certain syntax and when they are rendered, you see a beautiful document with headings, bullet points, code boxes and more. There are many Markdown editors available for Linux users but mostly they are two paned editors where you write in Markdown syntax in left and it gets rend

How I am Using Git and Obsidian for Note Version Management

by: Sreenath Sun, 05 Oct 2025 07:22:20 GMT Git is a powerful tool that helps you keep track of changes in your files over time. While it is highly popular among the developer community, you can use Git as a note storage vault. In this case, the source files are Obsidian markdown files. When you use Obsidian for note-taking, Git can be very useful to manage different versions of your notes. You can easily go back to previous versions, undo mistakes, and even collaborate with others. In this

by: Abhishek Prakash Fri, 03 Oct 2025 17:22:02 +0530 The Git for DevOps course has been converted into an eBook.

If you are not a Pro member yet, either opt for one and get access to everything we create or just purchase this eBook. One more chapter has been added to the systemd automation course.

FOSS Weekly #25.40: Fedora 43 Features, Kernel 6.17, Zorin OS 18, Retro Gaming Setup and More Linux Stuff

by: Abhishek Prakash Thu, 02 Oct 2025 04:43:03 GMT Last month, Austria's armed forces ditched Microsoft Office for LibreOffice. This is surely positive news, but it also makes us think about something crucial. The move to switch to open source is often driven by monetary benefits. Since these organizations often save a hefty amount, should they not contribute some part of their savings back to the open source project they are relying on? What do you think?

411: The Power of Tree-Sitter

by: Chris Coyier Wed, 01 Oct 2025 13:24:46 +0000 Alex and Chris hop on the show to talk about a bit of technology that Alex calls “The 2nd best technological choice he’s ever made.” That technology is called Tree-sitter. It’s a code parsing tool for building ASTs (Abstract Syntax Trees) out of code. GitHub uses it to power search and “go to” functionality. The creators now work on Zen, where a code parser is paramount. We use it to understand an entire Pen very quickly so we can understand how

Same Idea, Different Paint Brush

by: Geoff Graham Wed, 01 Oct 2025 13:02:47 +0000 There’s the idiom that says everything looks like a nail when all you have is a hammer. I also like the one about worms in horseradish seeing the world as horseradish. That’s what it felt like for me as I worked on music for an album of covers I released yesterday. I was raised by my mother, a former high school art teacher (and a gifted artist in her own right), who exposed me to a lot of different tools and materials for painting an

When Should Testing Start in the Development Process? – Complete Guide

by: Neeraj Mishra Wed, 01 Oct 2025 07:33:55 +0000 Typically speaking, developing software is a long series of stages that starts with requirements gathering to development to testing, to final release. Each stage requires the respective members to contribute to the final development of the product in their own capacity. The business analyst’s job is to collect requirements from the client and validate their feasibility with a technical architect. The technical architect studies the whole enviro
