Big-O notation is a simple way to think about how a program behaves as the amount of data grows. While modern computers are fast and memory is abundant, software engineering is rarely about what is st

An algorithm is simply a set of instructions you give a computer. Like telling a child: “If the light is red, stop. If it’s green, go.” For a long time, most algorithms worked this way.

Authentication and authorization are closely related—but they solve two very different problems. Authentication is about identity. It answers the question: “Who are you?”

But here’s the truth: Backend is just a computer somewhere in a room running some code. That’s all.

Every programming language we use today carries a legacy — decades of problem-solving, innovation, and community evolution. From C (1972) that birthed modern systems programming, to Python (1991) powe
