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

Chris’ Corner: AI for me, AI for thee

by: Chris Coyier Mon, 21 Jul 2025 17:54:20 +0000 Our very own Stephen Shaw was on an episode of Web Dev Challenge on CodeTV: Build the Future of AI-Native UX in 4 Hours. I started watching this on my computer, but then moved to my living room couch to put it on the big screen. Because it deserves it! It honestly feels like “real” TV, as good as any episode of a home renovation show or the like. Only obviously better as it’s straight down the niche of web maker nerds like us. All three team

A Primer on Focus Trapping

by: Zell Liew Mon, 21 Jul 2025 13:14:17 +0000 Focus trapping is a term that refers to managing focus within an element, such that focus always stays within it: If a user tries to tab out from the last element, we return focus to the first one. If the user tries to Shift + Tab out of the first element, we return focus back to the last one. This whole focus trap thing is used to create accessible modal dialogs since it’s a whole ‘nother trouble to inert everything else — but you don

Ansible Yum Module: Manage Red Hat Packages

by: Umair Khurshid Mon, 21 Jul 2025 17:00:49 +0530 Modern infrastructure operations depend on automation not only for efficiency, but also for repeatability. Among the many tasks automated in daily workflows, package management is one of the most frequent. For systems based on RPM package formats such as Red Hat Enterprise Linux (RHEL), CentOS, AlmaLinux, Rocky Linux, and older versions of Fedora, Ansible provides a native module that integrates directly with the yum package manager. While newe

I Made Kitty Terminal Even More Awesome by Using These 15 Customization Tips and Tweaks

by: Sreenath Mon, 21 Jul 2025 06:38:35 GMT "If there is a media out there, VLC can play it!". I want to say the same thing about Kitty and its versatility. If you didn't know already, Kitty is one of the most comprehensive terminal emulators available in Linux. It offers image support, ligatures, animated cursors, and a whole lot of productivity tweaks. I could write a mini-book if I had to explain each one in full detail. I am not going to do that. Instead, I'll share some of my favorite f

Why Linux Is the Backbone of Secure IoT Deployments

By: Janus Atienza Sat, 19 Jul 2025 16:11:31 +0000 Photo by Pixabay from Pexels The Internet of Things or IoT is changing a lot of industries. It connects devices and provides levels of automation that you can’t even begin to imagine. However, as connected devices are increasing, which is projected to reach more than 40 billion by 2030, security remains a major concern.  A single vulnerability in an IoT ecosystem can expose sensitive data, disrupt operations, and compromise entire networks. As

Getting Creative With Versal Letters

by: Andy Clarke Fri, 18 Jul 2025 16:12:05 +0000 A while back, our man Geoff Graham treated us to a refresher on the CSS initial-letter property, but how can you style drop and initial caps to reflect a brand’s visual identity and help to tell its stories? Here’s how I do it in CSS by combining ::first-letter and initial-letter with other unexpected properties, including border-image, and clip-path.

LHB Linux Digest #25.18: Journalctl Logs, Restore Containers, Bash Test, Better Diff and More

by: Abhishek Prakash Fri, 18 Jul 2025 17:00:30 +0530 The AWK series continues with two more chapters. I have changed my initial plan to completely publish the AWK series in a couple of weeks. Instead, I'll go for two new chapters each week. The good thing is that we also have an upcoming systemd series by our partner educator, and it should be published next week. I hope you like learning from these new series 💪 💡Next Friday (25th July) will be Sysadmin appreciation day. Would be nice to plan

How Managed Networks Support Scalable IT Infrastructure In Modern Enterprises

Getting Clarity on Apple’s Liquid Glass

by: Geoff Graham Thu, 17 Jul 2025 13:23:52 +0000 Folks have a lot to say about “liquid glass,” the design aesthetic that Apple introduced at WWDC 2025. Some love it, some hate it, and others jumped straight into seeing how to they could create it in CSS. There’s a lot to love, hate, and experience with liquid glass. You can love the way content reflects against backgrounds. You can hate the poor contrast between foreground and background. And you can be eager to work with it. All of those c

10 Best DevOps Automation Tools in 2025

by: Neeraj Mishra Thu, 17 Jul 2025 03:36:01 +0000 DevOps tooling has become mission-critical. What used to be a niche engineering function is now a core business driver. And with the DevOps automation market projected to hit $72.81 billion by 2032, your choice of tools can literally make or break your product velocity. Whether you’re a CTO at a scale-up, a DevOps engineer in the trenches, or a founder juggling release chaos, choosing the right automation tools is no longer optional, it’s strate

402: Bookmarks

by: Chris Coyier Wed, 16 Jul 2025 19:42:27 +0000 Pins are dead! Long live bookmarks! Pins was never a good name for the feature we have on CodePen where you can mark a Pen or Collection to more quickly jump back to it from anywhere on the site. The word is too similar to “Pen” that it’s just awkward, not to mention it’s not exactly and obvious metaphor. A bookmark is a much more clear term and icon, so we decided to switch to it. Switching the UI is kind of the easy part. It’s kind

What I Took From the State of Dev 2025 Survey

While the survey isn’t directly related to the code part of what we do for work, I do love the focus Devographics took ever since its inception in 2020. And this year it brought us some rather interesting results through the attendance of 8,717 developers, lots of data, and even more useful insights that I think everyone can look up and learn from. I decided to look at the survey results with an

Chris’ Corner: We Can Have Nice Things

The Curious Case of AUR Updates Fetching 30 GB of Data for Electron

by: Abhishek Prakash Tue, 15 Jul 2025 03:44:05 GMT I am using CachyOS on my primary system these days and pretty content with its performance. Since it is based on Arch Linux, I am using a few software installed from the Arch User Repository (AUR) with Yay AUR Helper. While updating, it showed me a few packages that required upgrades. I did not pay attention as there was nothing alarming and pressed the usual enter keys one after another. Only when it reached a certain stage that I realized

Setting Line Length in CSS (and Fitting Text to a Container)

by: Daniel Schwarz Mon, 14 Jul 2025 12:38:23 +0000 First, what is line length? Line length is the length of a container that holds a body of multi-line text. “Multi-line” is the key part here, because text becomes less readable if the beginning of a line of text is too far away from the end of the prior line of text. This causes users to reread lines by mistake, and generally get lost while reading. Luckily, the Web Content Accessibility Guidelines (WCAG) gives us a pretty hard rule to foll

The Layout Maestro Course

by: Geoff Graham Fri, 11 Jul 2025 17:07:13 +0000 Layout. It’s one of those easy-to-learn, difficult-to-master things, like they say about playing bass. Not because it’s innately difficult to, say, place two elements next to each other, but because there are many, many ways to tackle it. And layout is one area of CSS that seems to evolve more than others, as we’ve seen in the past 10-ish years with the Flexbox, CSS Grid, Subgrid, and now Masonry to name but a few. May as well toss in Container Q

Scroll-Driven Sticky Heading

by: Amit Sheen Fri, 11 Jul 2025 12:43:59 +0000 Scroll-driven animations are great! They’re a powerful tool that lets developers tie the movement and transformation of elements directly to the user’s scroll position. This technique opens up new ways to create interactive experiences, cuing images to appear, text to glide across the stage, and backgrounds to subtly shift. Used thoughtfully, scroll-driven animations (SDA) can make your website feel more dynamic, engaging, and responsive. A few
