Tutorials covering programming languages, type systems, architecture, tooling, and the patterns used to build software that lasts. Each chapter is standalone, built around real examples and verified facts.
Traefik is a reverse proxy that discovers Docker containers through the Docker socket and routes traffic to them based on labels attached to the container itself. The routing configuration is not a separate file that must be edited when a service is added; it is a set of traefik.http.routers.* and traefik.http.services.* labels on the container,…
The difference between SSR and SSG is not about the code you write. It is about when the HTML is generated. In both cases, React components render on a server, the output is HTML, and the browser receives a page that is already populated with content before any JavaScript runs. The distinction is the trigger:…
Rust’s desktop GUI story has two dominant approaches, and the distinction is architectural. egui is an immediate-mode GUI library: on every frame, the application describes the entire UI from its state, and egui renders it and handles input in the same pass. iced is a retained-mode framework modeled on The Elm Architecture: the application defines…
SQL is a set-based language. A SELECT returns the whole result at once, and the UPDATE affects every matching row in a single statement. Some tasks do not fit that model. A batch process that calls an external API per row, a data migration that must process the rows in a specific order with the…
React and TypeScript are two tools that solve different problems. React manages the UI. TypeScript manages the shapes of data. Together, they form a development environment where the compiler catches most of the mistakes that would otherwise surface at runtime — wrong prop names, missing state properties, event handlers with the wrong signature, and API…
Vue’s default reactivity is deep. A ref({ nested: { count: 1 } }) wraps every nested object in a Proxy, so mutating nested.count triggers a re-render. This is convenient, but it is also expensive for large data structures, external library instances, and immutable API responses that will never be mutated internally. shallowRef() and shallowReactive() provide…
Angular Material is the official UI component library for Angular, built and maintained by the Angular team. It implements Google’s Material Design specification, providing a set of high-quality, accessible, and customizable components that integrate deeply with the framework. Unlike third-party libraries that layer on top of Angular, Angular Material is designed alongside it — the…
Publishing a Dart package to pub.dev is a one-way operation: once a version is uploaded, it cannot be deleted or overwritten. The manual workflow is a sequence of validation steps that catch problems before the irreversible upload, and the automated workflow replaces the manual confirmation with an OpenID Connect token exchange that GitHub Actions can…
Docker’s persistence model creates a specific backup problem: named volumes and bind mounts hold the data that matters, but the container’s writable layer is disposable, and the image is reproducible from a registry. A backup strategy that copies the entire /var/lib/docker directory is fragile and often inconsistent; a strategy that stops the stack and tars…
React Server Components are not a rendering mode. They are a new kind of component. A Server Component runs ahead of time, in an environment separate from the client application and separate from the traditional SSR server, and its code never ships to the browser . That separation is the architectural core. The component can…
