Better Than Man pages? These Tools Help You Understand Linux Commands

by: Abhishek Prakash Tue, 27 May 2025 01:53:31 GMT How do you get help in the Linux command line? On Linux, there are man pages that come preloaded with any distribution. The man pages are basically help pages which you can access using the terminal. You get an instruction manual when you purchase a new gadget, right? It is just like that. If you want to know what a command does, just use the 'man' keyword followed by the command you would like to know about. While it may seem pretty strai

Guide to Using Plugins in Obsidian

by: Sreenath Mon, 26 May 2025 00:50:21 GMT Obsidian has emerged as a powerful and flexible knowledge management tool, despite NOT being an open source product. Using plugins is just one of the many tips that you can follow to get the most out of Obsidian. However, there is a small catch when it comes to compatibility. If you have used several Obsidian-specific plugins, then your notes may not be fully compatible in other plain markdown editors. In this article, we will take a look at Plu

What are MCP Servers and Why People are Crazy About It?

by: Abhishek Kumar Thu, 22 May 2025 07:40:49 GMT It took me way longer than I’d like to admit to wrap my head around MCP servers. At first glance, they sound like just another protocol in the never-ending parade of tech buzzwords decorated alongside AI. But trust me, once you understand what they are, you start to see why people are obsessed with them. This post isn’t meant to be the ultimate deep dive (I’ll link to some great resources for that at the end). Instead, consider it just a lil

FOSS Weekly #25.21: Oh My Bash, Ubuntu's New Terminal, Pixelify Android, Fedora's Wayland Gamble and More

by: Abhishek Prakash Thu, 22 May 2025 04:36:31 GMT I have an interesting story to share. You are probably already aware that many products and services offer a trial version for a limited time. And some people try to take advantage of the trial period by creating new accounts with new email addresses. But imagine if a multi-million dollar enterprise does the same. And it does so for an open source software that they could have managed on their own. Free as in Fraud? A $130M Aerospace Compa

Use Multi-Cursor in VS Code to Edit Multiple Lines Simultaneously

by: Abhishek Kumar Wed, 21 May 2025 02:40:20 GMT Working with code often involves repetition, changing variable names, updating values, tweaking class names, or adding the same prefix across several lines. If you find yourself making the same changes again and again, line by line, then multi-cursor editing in Visual Studio Code can help simplify that process. In this part of our ongoing VS Code series, we’ll take a closer look at this feature and how it can make everyday tasks quicker and

Those Blinking LEDs on Your Raspberry Pi Have Special Meanings

by: Abhishek Kumar Tue, 20 May 2025 03:07:08 GMT While setting up a Raspberry Pi 5 for a new project, I decided to go with a headless setup - no display, keyboard, or mouse. I flashed the SD card, connected power, and waited for the Pi to appear on my network. But nothing showed up. I scanned my network, double-checked the router’s client list, still no sign of the Pi. Without access to a display, I had no immediate way to see what was happening under the hood. Then I noticed something: the

Automatically Format Code On File Save in Visual Studio Code

by: Abhishek Kumar Sun, 18 May 2025 05:23:03 GMT Manually formatting code can be tedious, especially in fast-paced or collaborative development environments. While consistent formatting is essential for readability and maintainability, doing it by hand slows you down and sometimes leads to inconsistent results across a project. In this article, I’ll walk you through the steps to configure Visual Studio Code to automatically format your code each time you save a file. We'll use the VS Code

Handling Indentation in VS Code

by: Abhishek Kumar Wed, 14 May 2025 03:14:27 GMT Indentation is how code is visually spaced. It helps define structure, scope, and readability. For example, Python requires indentation to define blocks of code. Other languages might not require it, but messy indentation can make code really hard to read (and debug). Common indentation styles include: 2 spaces (popular in JS, HTML, CSS) 4 spaces (common in Python, Java) Tabs (some devs swear by them) VS Code lets you customize indentation p

How I Turned My Old Hi-Fi Speakers into Bluetooth Ones with Raspberry Pi

by: Abhishek Kumar Sat, 10 May 2025 06:49:14 GMT Sometimes I do weird things for the sake of it. Like once, I used Raspberry Pi as a WiFi extender for fun. This is one of those stories. I had an old pair of hi-fi speakers gathering dust in a forgotten corner of the house. The only problem? They needed a Bluetooth dongle and DAC to work, and I didn’t have either. But with my love for DIY and a determination to salvage my musical aspirations, I decided to take a different route. I thought o

Enable or Disable Word Wrap in VS Code

by: Abhishek Kumar Wed, 07 May 2025 11:06:19 GMT Word wrap automatically breaks a long line of text so it fits within your current editor window, without you needing to scroll horizontally. It doesn’t add line breaks to your file; it just wraps it visually. Picture this: You’re writing a long JavaScript function or a long SQL query. Without word wrap, you’d be endlessly dragging that horizontal scrollbar. With it, everything folds neatly within view. This is especially useful when: You're w

Tap into Potential: Add Premium Touch to Your Raspberry Pi Projects With SunFounder's 10-inch Display

by: Abhishek Prakash Wed, 07 May 2025 07:58:51 GMT I have got my hands on this 10 inches touchscreen from SunFounder that is made for Raspberry Pi like devices. If you are considering adding touch capability to your Raspberry Pi project, this could be a good contender for that. I have used a few SunFounder products in the past but the Pironman case made me their fan. And I truly mean that. This is why before I opened the package, I had a feeling that this will be a solid device. Let me sha

7 Essential Logseq Plugins I Use and Recommend

by: Sreenath Sat, 03 May 2025 08:56:47 GMT In an earlier article, I discussed installing plugins and themes in Logseq. And you already know that there are plenty of third-party plugins available in Logseq plugins Marketplace. Let me share some of the Plugins I use to organize my contents. 🚧Before installing Plugins, it is always good to frequently take backups of your notes. In case of any unexpected data loss, you can roll back easily.I presume you know it already, but in case you need hel

FOSS Weekly #25.18: Linux Magazine, Modern Terminals, Muse Pi, apt Guide and More

by: Abhishek Prakash Thu, 01 May 2025 05:49:00 GMT Before the age of blogs, forums, and YouTube tutorials, Linux users relied on printed magazines to stay informed and inspired. Titles like Linux Journal, Linux Format, and Maximum Linux were lifelines for enthusiasts, packed with tutorials, distro reviews, and CD/DVDs. These glossy monthly issues weren’t just publications—they were portals into a growing open-source world. Let's recollect the memories of your favorite Linux magazines. Ever

Exploring Firefox Tab Groups: Has Mozilla Redeemed Itself?

by: Sourav Rudra Thu, 01 May 2025 05:10:17 GMT Mozilla's Firefox needs no introduction. It is one of the few web browsers around that is not based on Chromium, setting out to provide a privacy-focused browsing experience for its users. Sadly, some recent maneuvers have landed it in hot water, the most recent of which was a policy change that resulted in an intense backlash from the open source community, who felt wronged. The consensus being that Mozilla broke their promise of not selling u

Journals and Contents: Two Special Pages in Logseq

by: Sreenath Wed, 30 Apr 2025 05:46:58 GMT Logseq is different from the conventional note-taking applications in many aspects. Firstly, it follows a note block approach, rather than a page-first approach for content organization. This allows Logseq to achieve data interlinking at the sentence level. That is, you can refer to any sentence of a note in any other note inside your database. Another equally important feature is the “Special Pages”. These are the “Journals” and “Contents” pages.

Dual Booting CachyOS and Windows

by: Abhishek Prakash Mon, 28 Apr 2025 06:04:44 GMT There is something about CachyOS. It feels fast. The performance is excellently smooth, specially if you have newer hardware. I don't have data to prove it but my new Asus Zenbook that I bought in November last year is rocking CachyOS superbly. The new laptop came with Windows, which is not surprising. I didn't replace Windows with Linux. Instead, I installed CachyOS in dual boot mode alongside Windows. The thing is that it was straightforw

Customize Logseq With Themes and Plugins

by: Sreenath Wed, 23 Apr 2025 03:05:46 GMT Logseq provides all the necessary elements you need for creating your knowledge base. But one size doesn't fit all. You may need something extra that is either too complicated to achieve in Logseq or not possible at all. What do you do, then? You use external plugins and extensions. Thankfully, Logseq has a thriving marketplace where you can explore various plugins and extensions created by individuals who craved more from Logseq, Let me show you

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

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

FOSS Weekly #25.16: Ubuntu 25.04, Fedora 42, ParticleOS and a Lot More Linux Stuff

by: Abhishek Prakash Thu, 17 Apr 2025 06:27:20 GMT It's the release week. Fedora 42 is already out. Ubuntu 25.04 will be releasing later today along with its flavors like Kubuntu, Xubuntu, Lubuntu etc. In the midst of these two heavyweights, MX Linux and Manjaro also quickly released newer versions. For Manjaro, it is more of an ISO refresh, as it is a rolling release distribution. Overall, a happening week for Linux lovers 🕺 💬 Let's see what else you get in this edition Arco Linux bids far
