Setting up an Ubuntu environment on WSL ready for development.

Containers vs. virtual machines, Docker's architecture and what happens under the hood.

How the browser turns CSS into pixels: the rendering pipeline, how selectors are matched, the cascade and the stages of a value, formatting contexts, the flexbox and grid algorithms, painting order, compositing and performance, and what modern CSS can do on its own.

A distributed event streaming platform: the log, topics and partitions, producers and consumers, replication, delivery guarantees, queues with share groups, the ecosystem and production patterns.

Why Kubernetes exists, the declarative model and reconciliation, the cluster architecture, what happens on a kubectl apply, the main objects, networking, configuration, probes, resources and scaling, with a local lab.

How to design large, scalable systems, and how to run a system design interview: requirements, estimates, building blocks and trade-offs.

Language basics, modules and packages, types, control flow, structs, pointers, goroutines, channels and generics.

What an architect does, the difference between architecture and design, why software must be sustainable, and the characteristics that guide every decision.
