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

An Experimental Setup - for Building Local First, Portable Embedded C++ pipeline with self-hosted CI

A experimental setup on how to build stack using “Woodpecker CI, Cosmopolitan, and Google Pigweed” for small firmware teams to automate build-test-flash pipelines for their embedded systems

The Embedded Engineer's Second Brain: PARA and CODE Systems

More information is not equal to more clarity, Here I have assembled a simple guide to turning information overload into clarity using Tiago Forte’s the CODE and PARA methods.

Portable and Secure C- A Practical Guide to MISRA C & CERT C

The C language has powered satellites, pacemakers, and aircraft flight computers for five decades. That longevity is not accidental, and neither is the discipline required to keep it safe.

Automating Hardware Testing with Python

Good measurement is extremely essential in testing, because acquired data drives key engineering decisions. While engineers prefer automated testing to minimise human error and accelerate the process of data acquisition. But automated testing is not all about running scripts on a loop. If not checked, automated testing can introduce incorrect conclusions and poor engineering decisions

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.

7 C++ Inheritance pain-points Rust Fixes Forever

Seven ways C++ inheritance can create issues, and how Rust’s composition model fixes them all. From diamond problems to fragile base classes, see why composition wins in the long run.

From Regulation to Implementation- Understanding Vehicle Cybersecurity legal Compliance & How Vehicle Cybersecurity Actually Gets Done

UNECE R155/R156 are regulatory requirements for vehicle cybersecurity and software updates, while ISO 26262 (functional safety) and IEC 62443 (industrial/IoT cybersecurity) are technical standards. The relationship is that UNECE mandates compliance at a regulatory level, and ISO/IEC standards provide the engineering frameworks and evidence manufacturers use to demonstrate compliance

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.

Pytest for Embedded Developers- Reliable, Maintainable Test Design

Embedded Software testing used to be dominated by only C or C++ with a bit of bash scripts, however in recent times the framework of firmware and embedded-software testing has been changing rapidly integrating Python’s flexibility & ease of usage, with the CI/CD integration the testing has never been faster & secured
