introduction I’ve always been intrigued by the idea of creating a home data center with Raspberry PIs as a computable instances. However, managing individuals node with SD cards is not fun 😼. So decided to try PXE (Preboot Execution Environment) booting. Instead of dealing with each SD card individually, PXE protocol lets me manage all my RPis from one central server, making updates and further patches easier. In this post, I’ll share how you can set up PXE booting for your RPi fleet and enjoy these benefits to :)...

In this post, I’ll walk you through how I resolved the error brcmfmac: brcmf_set_channel: set chanspec fail, reason -52 and successfully connected Raspberry Pi to a mobile hotspot....

Introduction UML diagrams play a crucial role in software engineering for visualizing and structuring information. This article explores the seamless automation of UML diagram creation using ChatGPT (LLM) and the PlantUML tool. The aim is to provide a valuable resource for Solutions Architects and engineers looking to efficiently communicate and pitch ideas through visual representations. In this tutorial, we’ll focus on visualization of the high-level system design of Netflix. By the end of this article, you’ll have a clear understanding of how ChatGPT and PlantUML can be harnessed to expedite the visualization of systems design while saving time on learning PlatUML syntax....

My Use case To establish a seamless synchronization of project files between a MacBook (working station) and a Raspberry Pi (hosting server), allowing for automatic updates and accessibility of the project from both devices. device/tool version DS420+ DSM 7.2-64570 Raspberry PI 400 The user begins working on the project using the IDE on the MacBook, editing and updating project files within the synchronized folder. As changes are made, they are automatically reflected in the synchronized folder and accessible on the Raspberry Pi in read-only mode....
