When preparing for software engineering or system design interviews, networking concepts often come up in subtle but important ways. Whether it’s choosing between REST, gRPC, or GraphQL, explaining how HTTP/3 improves performance, or troubleshooting latency issues in a distributed system, understanding the fundamentals can help you stand out. Let’s break down the key topics we discussed into an easy-to-digest guide. 1. OSI Model: The Foundation of Networking The OSI (Open Systems Interconnection) model is a conceptual framework that divides networking into seven layers, each with distinct responsibilities: ...

Managing Git via the command line is powerful, but let’s admit it—sometimes it feels overwhelming. That’s where LazyGit comes in! It’s a fast, lightweight, and interactive terminal UI for Git, helping you manage repositories without memorizing complex commands. What is LazyGit? LazyGit is a simple terminal-based UI for Git commands. Instead of typing multiple Git commands, you get a visual interface inside your terminal to handle: Staging files Committing changes Managing branches Viewing logs and diffs Handling stashes It’s perfect for developers who love terminal productivity but want to avoid command fatigue. ...

Once upon a time, there was a baker who baked the perfect giant cake. It was huge, heavy, and costly to make. People loved it, but soon everyone started asking for different flavors: “Can I get chocolate?” 🍫 “How about strawberry?” 🍓 “What if you add coffee and almonds?” ☕🌰 The baker sighed. “I can’t bake a new giant cake every time… it’s too expensive!” That’s when the idea struck: 👉 Don’t bake a new cake. Just add a topping. ...

In this brief tutorial, we’ll use FastMCP to transform an existing TODO application (which exposes an OpenAPI spec) into a MCP server and link it to CoPilot for organic task interactions. Step 1: The TODO App Your TODO app should already be running at: http://localhost:8000 And exposing its OpenAPI spec at: http://localhost:8000/openapi.json Step 2: Create the MCP Server Create a file todo_mcp_server.py: import httpx from fastmcp import FastMCP client = httpx.AsyncClient(base_url="http://localhost:8000") spec = httpx.get("http://localhost:8000/openapi.json").json() mcp = FastMCP.from_openapi(openapi_spec=spec, client=client) if __name__ == "__main__": mcp.run( transport="http", host="localhost", port=4200, path="/todo-mcp/http", log_level="debug", ) Run it: ...

As your app starts growing, one of the first things to feel the heat is your database. Queries slow down, reports get delayed, and your users start noticing. That’s when you start hearing scary words like replication, sharding, horizontal scaling… 😵‍💫 Don’t worry — scaling a database isn’t black magic. In fact, it’s a lot more manageable when you understand the core concepts. So, let’s break it down — one question at a time. ...

Software architecture has evolved significantly over the years to accommodate the growing complexity of applications. Three major architectural styles dominate the landscape today: Monolithic Architecture – The traditional, single-unit approach Service-Oriented Architecture (SOA) – A structured service-based model Microservices Architecture – A modern, modular approach to application design Each has its advantages and challenges, and understanding the differences is crucial when choosing the right architecture for a given application. In this blog post, we will explore: ...

In the ever-evolving world of software development, Serverless Architecture has emerged as a game-changer. It allows developers to focus purely on writing code without worrying about managing infrastructure. This results in cost efficiency, scalability, and rapid deployment cycles. In this blog post, we will explore: What Serverless Architecture is Key concepts and components Benefits and challenges Real-world use cases Best practices for implementation What is Serverless Architecture? Serverless Architecture is a cloud computing model where applications run without requiring developers to manage servers. While servers still exist, they are abstracted away by cloud providers who automatically handle provisioning, scaling, and maintenance. ...

Event-Driven Architecture (EDA) is a modern software design pattern that enables real-time processing, scalability, and decoupling of services. It has become a cornerstone of cloud-native applications, IoT systems, and financial services, allowing organizations to react to changes dynamically and efficiently. In this blog post, we will explore what EDA is, its key concepts, types, benefits, challenges, real-world use cases, and best practices. What is Event-Driven Architecture (EDA)? Event-Driven Architecture is a software design approach where the flow of the application is determined by events—changes in state that trigger reactions in different services. Unlike traditional request-response models, EDA enables asynchronous communication between components, reducing dependency and improving scalability. ...

Microservices architecture is a modern approach to building software applications as a collection of small, independently deployable services. It has gained immense popularity due to its scalability, flexibility, and resilience, making it an ideal choice for large, dynamic applications. In this blog post, we will explore what microservices architecture is, its key principles, components, benefits, challenges, comparisons with other architectures, and real-world use cases. What is Microservices Architecture? Microservices architecture is a software development approach where applications are composed of multiple small, independent services that communicate through APIs. Each microservice is responsible for a specific business function, such as user authentication, payment processing, or order management. ...

Service-Oriented Architecture (SOA) is a software design approach that enables the development of modular, reusable, and scalable applications. By structuring software as a collection of independent services that communicate over a network, SOA improves flexibility, maintainability, and interoperability. In this blog post, we will explore what SOA is, its core principles, components, benefits, challenges, real-world use cases, and best practices. What is Service-Oriented Architecture (SOA)? Service-Oriented Architecture (SOA) is a software design pattern where applications are built by integrating loosely coupled services. Each service is designed to perform a specific business function and can be accessed over a network through standardized communication protocols. ...
