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.

CSS Elevator: A Pure CSS State Machine With Floor Navigation

by: Christian Sabourin Fri, 29 Aug 2025 13:06:48 +0000 As a developer with a passion for state machines, I’ve often found myself inspired by articles like “A Complete State Machine Made with HTML Checkboxes and CSS.” The power of pure CSS-driven state machines intrigued me, and I began to wonder: could I create something simpler, more interactive, and without the use of macros? This led to a project where I built an elevator simulation in CSS, complete with direction indicators, animated transi

Single Docker Container Generated 20 GB of Log. Here's How I Reclaimed Disk Space

by: Abhishek Prakash Fri, 29 Aug 2025 12:40:58 +0530 I use Ghost CMS for my websites. Recently, they changed their self-hosting deployment recommendation to Docker instead of native installation. I took the plunge and switched to the Docker version of Ghost. Things were smooth until I got notified about disk running out of space. When I investigated to find which folders were taking the most space, I was surprised to see a Docker container taking around 21 GB of disk storage. And it was a cont

19 Beautiful Themes to Get a Better Visual Experience With VS Code

by: Abhishek Kumar Fri, 29 Aug 2025 03:43:22 GMT Let’s be honest, there’s nothing wrong with the default Visual Studio Code theme. It’s clean, it works, and I actually used it for quite a while. That is… until one day I stumbled upon a YouTube tutorial where the developer’s editor looked incredible. Sleek colors, stylish syntax highlighting, suddenly, my good ol’ default theme felt a little boring. That rabbit hole led me to explore the wonderful world of VS Code themes. Since then, I’ve t

Getting Creative With Images in Long-Form Content

by: Andy Clarke Mon, 25 Aug 2025 17:16:35 +0000 When you picture placing images in long-form content — like articles, case studies, or reports — the standard approach is inline rectangles, breaking up blocks of text. Functional? Sure. Inspiring? Hardly. Why do so many long-form articles feel visually flat? Why do images so often seem bolted on, rather than part of the story? And how does that affect engagement, comprehension, or tone? Images in long-form content can (and often should) d
