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

Thinking Deeply About Theming and Color Naming

by: Zell Liew Mon, 04 Aug 2025 13:14:45 +0000 As a front-end developer, I’ve been pretty curious about how other people code up their websites. So I tend to poke my head into design systems whenever I find one. Then, late last year, a conversation with Geoff Graham set me off thinking even deeper about theming websites. (If you don’t know that dude, he’s the chief editor of this site, so that guy’s a pretty big deal, too.) So I’ve been watching, pondering, and exploring: How can we

That's where journalctl's powerful filtering capabilities come to the rescue! To filter journalctl logs by a specific service, use the service name in the following manner: journalctl -u servicename The -u flag (short for "unit") is your primary tool for filtering logs by

Looking for an Ubuntu Manual? Try This Book

Follow Journalctl Logs in Realtime to Monitor System and Services

by: Abhishek Prakash Thu, 31 Jul 2025 13:05:49 +0530 The classic way of following a log file in real time is by using the tail -f command. But you know that journalctl logs are a different entity and they are not like plain text files in syslogs. So, how do you tail jounral logs then? It's simple. You use the similar -f option: journalctl -fThe -f flag (short for "follow") works just like tail -f but for systemd journals.

Making a Masonry Layout That Works Today

There were two main camps and a third camp that strikes a balance between the two: Use display: masonry Use grid-template-rows: masonry Use item-pack: collapse I don’t think they’ve came up with a resolution yet.

How to Discover a CSS Trick

A First Look at the Interest Invoker API (for Hover-Triggered Popovers)

by: Daniel Schwarz Wed, 23 Jul 2025 12:36:48 +0000 Chrome 139 is experimenting with Open UI’s proposed Interest Invoker API, which would be used to create tooltips, hover menus, hover cards, quick actions, and other types of UIs for showing more information with hover interactions. The Interest Invoker API makes these components declarative and hover-triggered, meaning that you create them with HTML, and then the web browser handles the mouseenter and mouseleave events for you, sans JavaScript.
