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. With cyber threats evolving daily, understanding key information security standards like ISO/IEC 27001:2022 is no longer optional, it’s essential. This international standard provides a robust framework for establishing, implementing, maintaining, and continuously improving an Information Security Management System (ISMS). For SysAdmins, mastering ISO/IEC 27001 isn’t

Chris’ Corner: Rounded Triangle Boxes and Our Shapely Future

by: Chris Coyier Mon, 21 Apr 2025 17:10:35 +0000 I enjoyed Trys Mudford’s explanation of making rounded triangular boxes. It was a very real-world client need, and I do tend to prefer reading about technical solutions to real problems over theoretical ones. This one was tricky because this particular shape doesn’t have a terribly obvious way to draw it on the web. CSS’ clip-path is useful, but the final rounding was done with an unintuitive feGaussianBlur SVG filter. You could draw it a

Linux SQL Server Database Recovery: Restoring Corrupt Databases

Tuning Local LLMs With RAG Using Ollama and Langchain

by: Abhishek Kumar Sun, 20 Apr 2025 14:46:21 GMT Large Language Models (LLMs) are powerful, but they have one major limitation: they rely solely on the knowledge they were trained on. This means they lack real-time, domain-specific updates unless retrained, an expensive and impractical process. This is where Retrieval-Augmented Generation (RAG) comes in. RAG allows an LLM to retrieve relevant external knowledge before generating a response, effectively giving it access to fresh, contextual

7 Utilities I Use to Boost Development Workflow Productivity

by: LHB Community Sun, 20 Apr 2025 12:23:45 +0530 As a developer, efficiency is key. Being a full-stack developer myself, I’ve always thought of replacing boring tasks with automation. What could happen if I just keep writing new code in a Python file, and it gets evaluated every time I save it? Isn’t that a productivity boost? 'Hot Reload' is that valuable feature of the modern development process that automatically reloads or refreshes the code after you make changes to a file. This helps th

Exploring Pages, Links, Tags, and Block References in Logseq

by: Sreenath Sat, 19 Apr 2025 13:00:24 GMT Simply creating well-formatted notes isn’t enough to manage the information you collect in daily life—accessibility is key. If you can't easily retrieve that information and its context, the whole point of "knowledge management" falls apart. From my experience using it daily for several months, I’d say Logseq does a better job of interlinking notes than any other app I’ve tried. So, without further ado, let’s dive in.

KubeTUI: Your Kubernetes Dashboard Right Inside Your Terminal

Pod status, service list, CrashLoopBackOff location, YAML configuration comparison, log view...... are almost daily operations! But to be honest, in the process of cutting namespaces, manually copying pod names, and scrolling the log again and again, I gradually felt burned out. That is, until I came across KubeTUI — a little tool that made me feel like “getting back on my feet”. W

It was added to Safari Technology Preview and can be tested now, as in, like, today. Slap this in a stylesheet and your paragraphs get a nice little makeover that improves the ragging, reduces hyphenation, eliminates typographic orphans at the end of the last line, and generally avoids large typographic rivers as a result.

Next Level CSS Styling for Cursors

Birth of Unix

While using Logseq, one thing to keep in mind is that the text formatting isn't pure Markdown. This is because Logseq uses bullet blocks as the basic unit of content and also supports Org-mode. Whenever you start a new document or press Enter after a sentence, a new block is created — and this block can be referenced from anywhere within Logseq. That
