GitFlow — What It Is and How to Use It GitFlow is a popular branching model for Git that defines a clear structure for feature development, releases, and hotfixes. It’s often used in DevOps and software teams to organize parallel development, testing, and deployment. 🧩 Core Idea GitFlow defines specific branches for different stages of the software lifecycle. Each branch has a clear purpose, which helps maintain stability in production while allowing parallel feature development. ...

Why Node.js is Single-Threaded Node.js is often described as a single-threaded runtime, and that’s true — but with some important details. To understand why, let’s look at JavaScript and the event loop mechanism. Why a Single Thread? JavaScript was originally designed to run in the browser’s single thread, to avoid complexity with the DOM and race conditions. Node.js inherits this principle: one thread for executing JavaScript code. This means only one piece of JS code executes at a time. ...

Who is DataOps and Why It Matters DataOps (Data Operations) is a methodology and role that focuses on improving the quality, speed, and reliability of data delivery for analytics and decision-making. If DevOps optimizes software delivery, and MLOps optimizes machine learning workflows, then DataOps ensures organizations can effectively manage and deliver data. What Does a DataOps Engineer Do? A DataOps engineer builds and maintains processes and infrastructure that guarantee fast and trustworthy data pipelines. ...

Who is MLOps and Why It Matters MLOps (Machine Learning Operations) is a discipline that combines machine learning (ML), development, and operations. If DevOps automates and speeds up software delivery, MLOps does the same but for machine learning models. What Does an MLOps Engineer Do? The role of an MLOps engineer is to ensure that ML models are not only trained but also reliably deployed, monitored, and maintained in production. ...

What are Unix Domain Sockets and How They Work When we think about communication between applications, we often imagine TCP or UDP over the network. But sometimes, processes don’t need to leave the machine at all. That’s where Unix Domain Sockets (UDS) come in. What is a Unix Domain Socket? A Unix Domain Socket is a special type of inter-process communication (IPC) mechanism in Unix-like systems. Instead of using IP addresses and ports, processes talk to each other via a file path on the filesystem (e.g., /var/run/docker.sock). ...
