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

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.

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

Chapter 2: Pattern Matching and Basic Operations

by: Abhishek Prakash Fri, 11 Jul 2025 17:35:12 +0530 Think of AWK patterns like a security guard at a nightclub - they decide which lines get past the velvet rope and which actions get executed. Master pattern matching, and you control exactly what AWK processes. Pattern matching fundamentals AWK patterns work like filters: they test each line and execute actions only when conditions are met. No match = no action. Here are some very basic examples of pattern matching: awk '/ERROR/ {print $0}' l

It’s been over 2 years.  We took a break after episode 400, not because we ran out of things to talk about, but because we were so focused on our CodePen 2.0 work, it got old not being able to discuss it yet. We’ll be talking plenty about that going forward. But CodePen has a ton of moving parts, so we’ll be talking about all of it.  This week we’ll be kicking off the podcast again talking about a huge

Packet is the Linux App You Didn’t Know You Needed for Fast Android File Transfers

Local file transfers are still relevant, letting people send files directly between devices on the same network without involving a nosy middleman (a server, in this case). Instead of uploading confidential documents on WhatsApp and calling it a day, people could share them directly over their local network. This approach is faster, more private, and mo

The Gap Strikes Back: Now Stylable

by: Patrick Brosset Tue, 01 Jul 2025 12:42:38 +0000 Four years ago, I wrote an article titled Minding the “gap”, where I talked about the CSS gap property, where it applied, and how it worked with various CSS layouts. At the time, I described how easy it was to evenly space items out in a flex, grid, or multi-column layout, by using the gap property. But, I also said that styling the gap areas was much harder, and I shared a workaround. However, workarounds like using extra HTML element

To be honest, I was a smidge skeptical. I know what a design token is. It’s a variable of a color or font-family or something. I pretty much only work on websites, so that exposes itself as a --custom-property and I already know that using those to abstract common usage of colors and fonts is smart and helpful. Done.
