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.
React’s component model is not bound to the browser. The same reconciliation engine that renders to the DOM in a web application can render to a Chromium window embedded in a desktop process, or to the operating system’s native webview. The two dominant frameworks that make this possible are Electron and Tauri, and they represent…
Extended Berkeley Packet Filter (eBPF) allows custom programs to run inside the Linux kernel without changing kernel source code or loading modules. For years, writing eBPF meant writing C and relying on libbpf and clang. The aya framework changes this: it is a pure-Rust library that lets you write both the kernel-side eBPF program and…
Change Data Capture is the pattern of detecting row-level changes—inserts, updates, and deletes—as they happen, and streaming them to downstream systems. The two dominant approaches in relational databases are log-based CDC, which reads the database’s transaction log, and trigger-based CDC, which installs database triggers that write to an audit table. Debezium is the de-facto open-source…
Angular Schematics is the scaffolding engine behind every ng generate command. When you run ng generate component, ng add, or ng update, a schematic executes: it reads a template, applies transformations, writes files into the project’s virtual file tree, and returns the modified tree. The same engine is available to you, which means you can…
React Three Fiber is a React renderer for three.js, not a wrapper library. It does not add an abstraction layer between React and the 3D scene; it replaces the DOM as the rendering target. The component tree you write is the scene graph, and mounting a <mesh> creates a THREE.Mesh that is added to the…
Rust’s default build path assumes the host machine and the target machine are the same. A standard cargo build compiles for the host architecture, links against the host’s C library, and produces a binary that runs on the machine that produced it. Cross-compilation breaks this assumption. The toolchain must be told which target to build…
A Foreign Data Wrapper is PostgreSQL’s implementation of the SQL/MED standard: a library that lets the database treat data residing outside PostgreSQL as if it were a local table . The wrapper handles the protocol for connecting to the external source, fetching rows, and returning them to the PostgreSQL executor. The postgres_fdw extension is the…
Angular CLI builders are the engines behind every ng command. When you run ng build, ng serve, ng test, or ng lint, the CLI reads the workspace configuration, resolves the target to a builder, and invokes it with the options from angular.json. A builder is a function that receives options and a context and returns…
React does not have a native canvas element. The <canvas> tag is a DOM element, and the drawing context is an imperative API that sits outside React’s declarative model. Interactivity—detecting a click on a shape, hovering over a pixel, dragging a node—requires translating DOM events into coordinates that the canvas understands, and then deciding whether…
Single Instruction, Multiple Data (SIMD) allows a CPU to process multiple values with a single instruction. On modern x86_64 processors, this means adding four f32 values in the time it takes to add one, or processing eight u8 values in a single operation. Rust provides two primary paths to SIMD: the std::arch module, which exposes…
