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.

Breaking Boundaries: Building a Tangram Puzzle With (S)CSS

by: Sladjana Stojanovic Thu, 12 Jun 2025 13:58:38 +0000 For years, I believed that drag-and-drop games — especially those involving rotation, spatial logic, and puzzle solving — were the exclusive domain of JavaScript.

Chris Corner: For The Sake of It

by: Chris Coyier Mon, 09 Jun 2025 16:37:09 +0000 I love weird design ideas. Probably because so much of what we need to do as web designers is, appropriately, somewhat serious. We want things to be simple, clear, professional, so that people understand them and in many cases pay for them. So when the constraints relax, so can we. It’s unlikely that Taylor’s homepage would “perform well” in any sort of UX testing, but who cares? It’s not impossible to use, it’s just unusual. And crucially, i

Creating an Auto-Closing Notification With an HTML Popover

by: Preethi Mon, 09 Jun 2025 12:58:37 +0000 The HTML popover attribute transforms elements into top-layer elements that can be opened and closed with a button or JavaScript. Most popovers can be light-dismissed, closing when the user clicks or taps outside the popup. Currently, HTML popover lacks built-in auto-close functionality, but it’s easy to add. Auto closing popups are useful for user interfaces like banner notifications — the new-message alerts in phones, for instance. A picture
