Simplify Your Day As Developer

Performance is often the reason developers choose C++ , but with great power comes great responsibility. C++20 introduced many modern conveniences — ranges, coroutines , smart pointers, structured bindings — but if misused, they can lead to subtle and painful performance regressions . In this post, we’ll look at five common C++20 performance pitfalls , why they happen, and what you can do to avoid them — with examples along the way.

Copying Instead of Moving One of the easiest mistakes in modern C++ is accidentally triggering deep copies instead of moves . ❌ The Pitfall std::vector<std::string> names = getNames (); std::vector<std::string> copy = names; // Copies all elements Even if getNames() returns a temporary, a careless assignment or a missing std::move() can lead to unnecessary heap allocations and data duplication. ✅ The Fix Use move...

Microservices are awesome — until you realize you’ve spent half your budget just wiring them up. If you’ve ever created a dozen projects, configured dependency injection, set up logging, and still felt like you’re not writing actual business code , you’re not alone. The good news? With .NET 8 , building a lightweight, budget-friendly microservice has never been simpler. Let’s walk through how you can build one with minimal boilerplate , without losing the essentials. Recommended Watch :  Minimal Web API Why Budget-Friendly Microservices Matter Before we dive into code, let’s talk about the why . Microservices promise scalability, modularity, and independent deployments — but they can also become a maintenance nightmare if you over-engineer them. The trick is to start simple , then add complexity only when necessary . This not only saves development effort but also reduces hosting and maintenance costs — perfect for startups, side projects, or indie developers. 🧱 Step 1: Star...

Introduction Design patterns are essential tools in a developer’s toolkit. Among them, the Chain of Responsibility Design Pattern stands out as a clean way to decouple request senders from receivers. Traditionally, this pattern is implemented using class hierarchies where each handler either processes the request or passes it down the chain. While effective, the classical approach can be verbose and inflexible. With the advent of C++20 coroutines , we now have the power to rethink how we implement such patterns. Coroutines offer a lazy, resumable, and composable mechanism that naturally aligns with the idea of passing control across a chain. In this post, we’ll explore how to modernize the Chain of Responsibility pattern using coroutines, leading to more readable, testable, and flexible code. Whether you're an intermediate developer or a seasoned C++ programmer, this article will show you how modern C++ features can revitalize well-known design patterns. What is the Chain of...

What Is a Blockchain? Shared Google Doc Analogy Just like you and your friends all see the same live document, every participant (node) in a blockchain network holds a full copy of the ledger. If Alice adds a sentence, Bob instantly sees it—on-chain, if one node confirms a transaction, all nodes update too. Decentralized Ledger Traditional ledgers live on one server (a bank, company, etc.). If it’s hacked or fails, you’re out of luck. Blockchain copies that ledger to hundreds or thousands of nodes around the world—no single point of failure. Immutable Records Each new entry becomes part of an immutable chain. To change it, you’d have to re-write every subsequent block on every node—practically impossible. How It Works in 3 Steps Gather Transactions → Make a Block Users broadcast transactions (“Alice pays Bob 2 BTC”). Nodes collect these into a candidate block—like packing letters into an envelope. Each block can hold thousands of transactio...

NFT: Non-Fungible Token NFT? Sounds Fancy. What Does It Even Mean? Alright, let’s start with the acronym. NFT stands for Non-Fungible Token. Wild name, right? Here’s what it actually means:  Non-Fungible: Imagine you have a dollar bill. You can trade that dollar for any other dollar, and you’re still cool—you’ve got the same thing. Dollars are fungible. But think about a rare baseball card or a one-of-a-kind painting. You trade your original Picasso for a Van Gogh? Nah, that’s not the same deal. That’s non-fungible—unique, irreplaceable stuff.  Token: In the digital world, a token is just a fancy word for a digital certificate stored on a blockchain (we’ll get into that next). So, NFT is basically a digital certificate of ownership for a one-of-a-kind item. That item could be digital art, a tweet, a virtual real estate plot, a music track—heck, even a virtual pet.  The Blockchain: Your Digital Ledger Before we go full throttle into NFTs, you must know about blockchain. If...

 C++20 has redefined modern C++ programming with powerful features like concepts and requires clauses. This comprehensive guide is tailored for young professionals and college students, helping you leverage these new tools to write safer, more maintainable code. Throughout this article, you'll find practical code examples. Suggested Reads on templates : CRTP  , Partial Template Specialization  , Perfect Forwarding What Are C++20 Concepts? C++20 Concepts allow you to constrain template parameters directly in your code, ensuring that only types meeting specific requirements are accepted. This feature acts as a compile-time predicate and is essential for creating clear and robust templates. How Concepts Work Concepts enable you to specify what properties a type must have. They improve code readability by making your intentions explicit and significantly enhance error messages when template constraints aren’t met. For example, consider a function designed to add two values on...
