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.
Angular 17 introduced a new built-in control flow syntax that replaces the structural directives *ngIf, *ngFor, and *ngSwitch with blocks prefixed by @. The new syntax is baked into the template, which means CommonModule is no longer required for these directives, and the compiler can pre-compile the blocks for better performance and type checking. This…
A micro-frontend is an architectural pattern where a large application is composed from independently developed, independently deployed frontend fragments. Web Components are a browser-native mechanism for encapsulating markup, styles, and behavior into a custom element. The combination is appealing because it promises framework-agnostic composition: a React shell can host a Vue micro-frontend, or a legacy…
A compiled Rust binary is not a black box. The machine code can be disassembled, the data sections can be read, and the control flow can be reconstructed. For developers shipping proprietary algorithms, licensing logic, or security-sensitive code, this visibility is a liability. The defense is layered: stripping symbols removes the map that makes reverse…
Database unit testing frameworks exist because the logic inside stored procedures, functions, and triggers is code, and code that is not tested accumulates defects silently. The challenge is that database code does not return values or throw exceptions in the way that application code does. A stored procedure communicates through result sets and output parameters….
Upgrading a legacy Angular application is rarely a single task. It is a sequence of decisions: which Angular version the application is on, whether the codebase still uses NgModules or standalone components, whether the build system is the old webpack-based one or the new esbuild-based one, and whether the application was originally written in AngularJS…
Every React build is a sequence of AST transformations. JSX becomes React.createElement or jsx() calls, TypeScript types are stripped, and the React Compiler inserts memoization. The tools that perform these transformations—Babel and SWC—expose plugin APIs that let developers add their own passes to the pipeline. A custom plugin can inject instrumentation, rewrite imports, enforce architectural…
Fuzzing is the automated art of throwing malformed, mutated, and malicious inputs at a program until it breaks. In C and C++, a fuzzer’s goal is memory corruption: heap overflows, use-after-free, and out-of-bounds writes. In safe Rust, those specific bugs are impossible—the compiler eliminates them. But this does not make fuzzing irrelevant. It shifts the…
Database benchmarking is the discipline of measuring a system’s performance under a workload that is defined, repeatable, and representative of the use case. The three tools that dominate the conversation serve different purposes. sysbench is a lightweight, multi-threaded benchmark tool for quick impressions of system performance, with built-in tests for CPU, memory, file I/O, and…
Architecture is the set of decisions that determine how an application is organized, how its parts communicate, and how it changes over time. Angular provides the primitives — components, services, dependency injection, routing, signals — but it does not prescribe how to combine them. That prescription is the architect’s job, and it is where most…
React is not a web framework. It is a reconciler: an algorithm that diffs a component tree and produces a stream of mutations. The react-dom package is one host of that algorithm, rendering to the browser’s DOM. React Native is another, rendering to native mobile views. A custom renderer is a third, and the react-reconciler…
