Getting Started with MetricMQ on ESP32
MetricMQ is a 328 KB C++20 message broker built from scratch and still under development. It features a custom binary wire protocol, Ed25519 message signing enforced at the wire level, exactly-once delivery using sequence IDs with LMDB persistence, Prometheus metrics on every message path, and a native ESP32 Arduino client. This page shows the broker running four demos, each highlighting a different capability with live Prometheus metrics you can watch in real time.

Why Most Embedded Software Is Overcoupled - And How Dependency Injection Fixes It ??
Most embedded bugs aren’t hardware problems. They’re design problems , born from code that grew organically across board revisions, tightly knotted around pin numbers, register addresses, and brittle HAL calls scattered everywhere and with scalability things can get messy, adding to the technical debt. Its important we talk about how not to make your embedded software tightly coupled and leave room for extension & scalibility

std::pmr in Embedded C++ - Predictable Memory Without the Heap
A practical embedded-first guide to std::pmr: what it solves, where it fits, how to size buffers safely, and when to prefer a custom allocator or plain static storage instead.

RAII in C++ vs Rust- How Each Language Manages Resources Without the Garbage collector
Managing memory and resources like files, network connections, or locks is essential in programming. While some languages rely on garbage collectors for automatic cleanup (Java), C++ and Rust use RAII (Resource Acquisition Is Initialization) to handle this deterministically.
