Understanding CPU-Bound vs I/O-Bound Workloads: A Practical Guide for Engineers

Modern software systems operate under many performance constraints, yet two concepts appear repeatedly in technical discussions: CPU-bound and I/O-bound workloads. These terms describe the dominant factor limiting a program’s performance.

Dissecting a DNS Response Packet: A Deep Dive into Network Communication Layers

Dissecting a DNS Response Packet: A Deep Dive into Network Communication Layers

When you type a website address like httpbin.org into your browser, a series of invisible yet intricate processes take place to resolve that human-readable name into an IP address. The image above captures one such process — a DNS (Domain Name System) response packet, analyzed using Wireshark. In this article,

Software Engineers Are Not Paid to Write Code — They’re Paid to Solve Problems

Software Engineers Are Not Paid to Write Code — They’re Paid to Solve Problems

There’s a common misconception in the tech world — especially among junior developers — that the value of a software engineer lies in how much code they can write, how many languages they know, or how many frameworks they can list on their résumé. But the truth is much simpler — and

Understanding Strings in Go — More Than Just Text

Understanding Strings in Go — More Than Just Text

When you first start working with Go (Golang), strings might appear simple. You wrap some text in quotes, concatenate them, print them — and everything seems fine. But under the hood, strings in Go are not just a series of characters. They are far more structured, optimized, and — for many beginners
