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

Getting Creative With Small Screens

by: Andy Clarke Wed, 29 Oct 2025 16:22:28 +0000 Over the past few months, I’ve explored how we can get creative using well-supported CSS properties. Each article is intended to nudge web design away from uniformity, toward designs that are more distinctive and memorable. One bit of feedback from Phillip Bagleg deserves a follow up: Fair point well made, Phillip. So, let’s bust the myth that editorial-style web design is impractical on small screens.

415: Babel Choices

by: Chris Coyier Tue, 28 Oct 2025 18:07:00 +0000 Robert and Chris hop on the show to talk about choices we’ve had to make around Babel. Probably the best way to use Babel is to just use the @babel/preset-env plugin so you get modern JavaScript features processed down to a level of browser support you find comfortable. But Babel supports all sorts of plugins, and in our Classic Editor, all you do is select “Babel” from a dropdown menu and that’s it. You don’t see the config nor can you chan

Automating XSS Hunting with Dalfox [Pen Testing Hands-on]

It auto-injects, verifies (headless/DOM checks included), and spits out machine-friendly results you can act on. Below: installing on Kali, core commands, handy switches, and a demo scan against a safe target. Copy, paste, profit. (lab-only.)

Pure CSS Tabs With Details, Grid, and Subgrid

by: Silvestar Bistrović Mon, 27 Oct 2025 14:33:17 +0000 Making a tab interface with CSS is a never-ending topic in the world of modern web development. Are they possible? If yes, could they be accessible? I wrote how to build them the first time nine long years ago, and how to integrate accessible practices into them. Although my solution then could possibly still be applied today, I’ve landed on a more modern approach to CSS tabs using the <details> element in combination with CSS Gr

Community Strikes Back: 12 Open Source Projects Born from Resistance

by: Pulkit Chandak Mon, 27 Oct 2025 07:34:29 GMT When open source is spoken about, it is done so just as a licensing model for software. But when you think about it, it is often deeper than just that. With the open source philosophy, developers make good software exist just for the sake of its existence. Sometimes this good software is so good, that it disrupts the already existing players of the area, tipping the balance entirely. We'll be looking at the most significant cases of such an e

Ghostty Terminal: Never Understood the Hype Until I tried it

by: Abhishek Prakash Sun, 26 Oct 2025 14:37:47 GMT When I first started using Linux, I did not care much about the terminal applications. Not in the sense that I was not using the terminal but more like I never cared about trying other terminal application (or terminal emulators, if you want to use the correct technical term.) I mean, why would I? The magic is in the commands you run, after all. How does it matter if it's the default terminal that comes with the system or something else? Mo

CSS Animations That Leverage the Parent-Child Relationship

by: Preethi Fri, 24 Oct 2025 14:18:03 +0000 Modern CSS has great ways to position and move a group of elements relative to each other, such as anchor positioning. That said, there are instances where it may be better to take up the old ways for a little animation, saving time and effort. We’ve always been able to affect an element’s structure, like resizing and rotating it. And when we change an element’s intrinsic sizing, its children are affected, too. This is something we can use to our

We use it because we have a GraphQL API and Apollo helps us write queries and mutations that go through that API.

It all starts with what we call reconnaissance—the art of gathering intelligence. Think of it like casing a building before a security audit; you need to know the doors, windows, and air vents first. In this digital age, one of the go-to tools for this initial legwork is TheHarvester. At its heart, TheHarvester is a Python script that doesn't
