Introduction Microservices promise speed, scalability, and team autonomy by decomposing a system into small, independently deployable services. But they also introduce complexity in distributed systems, data consistency, and operational overhead. This in-depth, zero-to-hero guide walks you through microservices architecture from fundamentals to production-ready practices. You’ll learn when to choose microservices, how to design services and APIs, what tooling to adopt, and how to deploy, secure, and observe them at scale. Code snippets and reference patterns are included to bridge theory and practice. We end with curated resources for further study. ...

Introduction WebAssembly (Wasm) is a portable binary instruction format designed to run high-performance code on the web and beyond. It lets you compile code from languages like C/C++, Rust, Go, and others into a compact, fast, and secure module that executes at near-native speed in browsers, servers, edge environments, and embedded systems. In this in-depth guide, you’ll learn: What WebAssembly is and how it works How to write and run your first Wasm module (step-by-step) Toolchains for C/C++, Rust, Go, and AssemblyScript How to integrate Wasm with JavaScript in the browser and with WASI on servers Performance strategies, memory and interop, threads and SIMD Debugging, testing, packaging, and deployment Advanced topics: Component Model, WASI, reference types, GC, and more Common pitfalls and best practices A curated list of resources to go further Whether you’re a web developer, systems programmer, or platform engineer, this guide will take you from zero to hero with Wasm. ...

Introduction If you put anything on the internet—an API, a website, an admin portal—you need SSL/TLS. It’s what turns http into https, encrypts traffic, and lets users verify they’re talking to the right server. But “turn on TLS” hides a lot of complexity: ciphers, certificates, OCSP, mTLS, key rotation, HTTP/2, QUIC, and more. This in-depth, zero-to-hero guide demystifies SSL/TLS. You’ll learn the concepts, how the protocol works, how to issue and deploy certificates, how to configure popular servers securely, how to test and monitor, and how to avoid common pitfalls. By the end, you’ll be able to ship production-grade TLS with confidence. ...

Introduction Webhooks are the backbone of modern, event-driven integrations. Instead of continuously polling an API to ask “has anything changed yet?”, webhooks let services push events to your application as soon as they happen: a payment succeeds, a repository receives a push, a customer updates their profile, or a ticket is assigned. This in-depth tutorial will take you from zero to hero. You’ll learn: What webhooks are and how they compare to polling and WebSockets How to build robust webhook receivers in multiple languages Signature verification, replay protection, and other security best practices Idempotency and reliable processing with retries and dead-letter queues How to test locally using tunnels and inspector tools How to design and operate your own webhook provider at scale Links to the best official docs and tools in the ecosystem If you’re implementing webhooks for the first time or trying to harden your production setup, this guide will meet you where you are and help you ship with confidence. ...
