Most of the time when we say “my model learned something,” what it actually learned is a bunch of very smart correlations. If users who click A also tend to click B, or if certain pixels tend to appear together in cat photos, our models will happily latch onto those patterns and exploit them. That’s powerful—and often enough for prediction—but it’s not the same as understanding what would happen if we actually changed something in the world: raised a price, changed a policy, or shipped a new feature.

This is part of my Docker Basics series — introductory guides to help you get started with Docker, learn key concepts, and build your skills step by step. Part 1: Understanding Container Part 2: Basic Commands Part 3: Dockerfile Part 4: Networks Docker Fundamentals (Part 1) Software systems frequently exhibit environment-dependent behavior: dependency versions drift, filesystem paths diverge, and minor operating-system differences produce major failures. Containerization addresses this by packaging an application together with its runtime dependencies so that a single artifact executes consistently across development laptops, continuous-integration pipelines, and production clusters.

Part 1: Understanding Container Part 2: Basic Commands Part 3: Dockerfile Part 4: Networks Common Commands This is a no-frills cheat sheet for the Docker commands you’ll reach for most of the time, with tiny runnable examples you can copy/paste. The most common commands you can use are the following:

This is part of my Docker Basics series — introductory guides to help you get started with Docker, learn key concepts, and build your skills step by step. Part 1: Understanding Container Part 2: Basic Commands Part 3: Dockerfile Part 4: Networks Basic Commands A Dockerfile is essentially a text file with a predetermined structure that contains a set of instructions for building a Docker image. The instructions in the Dockerfile specify what base image to start with (for example, Ubuntu 20.

This is part of my Docker Basics series — introductory guides to help you get started with Docker, learn key concepts, and build your skills step by step. Part 1: Understanding Container Part 2: Basic Commands Part 3: Dockerfile Part 4: Networks Docker Networking Docker offers four built-in network drivers: none, bridge, host, and overlay. Bridge (default): Creates an isolated, software-defined network. Containers on the same bridge get private IPs and can communicate with each other, while anything outside can’t reach them unless you explicitly publish ports.

Introduction AI has already changed how we interact with technology. The real shift is happening now with agents: AI systems that can reason, make decisions, and take action. Unlike a chatbot that passively replies, an agent can break down complex tasks, call APIs or databases, use tools, and deliver structured results. This is what makes the idea of Agentic AI so powerful — it’s not just about conversation, it’s about problem-solving with initiative.
