CDPATH: The Forgotten Magic Trick in Your Bash Toolbox

by: Abhishek Prakash Fri, 25 Apr 2025 20:55:16 +0530 If you manage servers on a regular basis, you'll often find yourself entering some directories more often than others. For example, I self-host Ghost CMS to run this website. The Ghost install is located at /var/www/ghost/ . I have to cd to this directory and then use its subdirectories to manage the Ghost install. If I have to enter its log directory directly, I have to type /var/www/ghost/content/log. Typing out ridiculously long paths that

In retrospect, GitOps is really a leap forward in the history of K8s Ops. Nowadays, the two hottest players in GitOps tools are Argo CD and Flux CD, both of which I've used in real projects. So I'm going to talk to you from the perspective of a K

grep: Multiple String Search Feature

By: Edwin Fri, 25 Apr 2025 05:28:30 +0000 The “grep” command is short for “Global Regular Expression Print”. This is a powerful tool in Unix-based systems used to search and filter text based on specific patterns. If you work with too many text-based files like logs, you will find it difficult to search for multiple strings in parallel. “grep” has the ability to search for multiple strings simultaneously, streamlining the process of extracting relevant information from files or command output

The Lost CSS Tricks of Cohost.org

by: Blackle Mori Thu, 24 Apr 2025 12:49:42 +0000 You would be forgiven if you’ve never heard of Cohost.org. The bespoke, Tumblr-like social media website came and went in a flash. Going public in June 2022 with invite-only registrations, Cohost’s peach and maroon landing page promised that it would be “posting, but better.” Just over two years later, in September 2024, the site announced its shutdown, its creators citing burnout and funding problems. Today, its servers are gone for good. Any li

Using Docker Compose with Host Network Configuration

by: Abhishek Kumar Thu, 24 Apr 2025 11:57:47 +0530 When deploying containerized services such as Pi-hole with Docker, selecting the appropriate networking mode is essential for correct functionality, especially when the service is intended to operate at the network level. The host networking mode allows a container to share the host machine’s network stack directly, enabling seamless access to low-level protocols and ports. This is particularly critical for applications that require broadcast

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

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?

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. The concept of page, links, an
