JavaScript Duplicate Encoding: Filter vs Hash Map Performance

In the V programming language, responsibility is shared between the programmer and the compiler: ✅ Programmer: decides when to use pointers or value structs, manages mutable state, and ensures runtime safety. ⚙️ Compiler: checks syntax, enforces types, and provides basic compile-time safety. This trade-off gives you flexibility—but also demands careful thinking about ownership, mutability, and runtime behavior. 📊 Check the visual summary below for a clear picture of the balance between freedom and responsibility in V. #VLang #Programming #SoftwareDevelopment #CodingTips #TechEducation

Can you tell what the output is? It is quite surprising! You might expect "Derived: 99", or perhaps "Base: 1". But if you are familiar with C++'s unique quirks, you might have guessed that the answer is actually a mix of both: "Derived: 1". In C++, virtual functions are dynamically bound at runtime, meaning it correctly calls the Derived class's implementation. However, when a virtual function is called with no parameters, the default arguments are decided based on the static type of the object. So what happens is that the compiler looks at the type of the pointer, which is of type Base*, sees that the default argument is 1, and silently injects 1 into the function call before routing it to the Derived class. The result is a hybrid execution. The compiler routes the call to the Derived class, but feeds it the Base class's default argument. Default arguments are statically bound, while virtual functions are dynamically bound. When you override a virtual function, the default arguments from the base class are not automatically acquired. #Cpp #SoftwareEngineering #Programming #CleanCode #TechTips

Assembly is a low-level programming language that communicates directly with computer hardware. Unlike Python or JavaScript, there is no automatic memory management or high-level abstractions, you manually manage registers and memory addresses to store and manipulate data. Common assembly architectures include RISC-V, ARM, MIPS, and x86. 𝗪𝗵𝗮𝘁 𝗶𝘀 𝗥𝗜𝗦𝗖-𝗩?

Your static initializer logic could silently break your class. You define a static property that depends on another static property declared later. Then you log both values. In production the first value becomes NaN, corrupting downstream calculations. Error logs show unexpected numbers, leading to wasted debugging time. Automated tests may miss it if they only check the second property. Comment A, B, C, or D with your reasoning. #typescript #programming #codinginterview #backend

🔥 const vs readonly in C# — Most devs use them wrong They both prevent modification. But they are NOT the same thing. 📌 const — compile-time constant • Replaced inline by the compiler • Must be a primitive or string • Cannot be assigned at runtime • Fastest performance 📌 readonly — runtime constant • Set once inside the constructor • Accepts any type • Different value per instance • Evaluated when the app runs ✅ When to use each: → Use const for true mathematical constants (Pi, DaysInWeek) → Use readonly for values known only at runtime → Prefer static readonly in libraries to avoid versioning bugs → Use readonly when the value differs per instance The golden rule? When in doubt → readonly is almost always the safer choice. #csharp #dotnet #programming #softwaredevelopment #cleancode

In C++, some standard library algorithms provide counted overloads that take a begin iterator plus a number of elements. With C++20, std::counted_iterator adapter generalizes this pattern, making any algorithm usable as a counted variant. --- ♻️ 𝑅𝑒𝑝𝑜𝑠𝑡 𝘢𝑛𝘥 𝐹𝑜𝑙𝑙𝑜𝑤 Mehdi Sagar 𝑖𝑓 𝑦𝑜𝑢 𝑎𝑟𝑒 𝑖𝑛𝑡𝑒𝑟𝑒𝑠𝑡𝑒𝑑 𝑖𝑛 𝘴𝑖𝘮𝑖𝘭𝑎𝘳 𝑡𝑜𝑝𝑖𝑐𝑠. #cpp #cplusplus #moderncpp #cpp17 #cpp20 #cpp23 #coding #code #programming #named #parameter #array #typesafety #tech #future #embedded #software #iterator #cleancode #ranges #views #memorysafety
