Building a MIL-STD-188-110 HF Modem in Modern C++: An Introduction
A weekly deep dive into a fixed-frequency serial-tone waveform, one block at a time. High-frequency (HF) radio is the communications system that ref…
The Map Dropped a Key When Two Expiry Times Matched
A C++ map can drop a live cache entry. One <= in a comparator is enough. I forced a timestamp tie and watched a key vanish. Would you have caught…
No one asked, but I've written a C++ header-only library so you don't have to declare the variable again.
In my spare time, I wrote a header-only C++ library that will help you extract variable declarations from the main(...) function of one .cpp file to…
The Compiler as Validator: When a Free Model's Wrong C++ Is Still Cheap
A free model will write wrong C++ template code. That is not a problem when the compiler is the validator. In this experiment, a free model wrote te…
Lightweight, native HTTP client built in C++20 — a fast, local-first alternative to Postman and Insomnia
The project is actively developed, and I'm committed to supporting anyone who tries it. If you encounter any issues, I'm glad to help, and any feedb…
Properties First, Fixtures Second, Flakes Never: A Test Contract for Agent Patches
An agent patch is a hypothesis. A test suite is the only evidence a reviewer gets. Most suites fail at that job in three reproducible ways: assertio…
The 3% Drop That Only Showed Up on a Clean Server: A Debugging Retrospective
My forwarder lost 3% of its messages. My laptop reported zero. CI reported zero. Staging lost thousands every hour. I blamed the network. I blamed t…
Mutation Testing as a Merge Gate for Agent-Written Tests
An agent patch that passes its own tests is a baseline, not a verdict. The same model wrote the code and the tests, so both share the same blind spo…
The Fix That Passed Review and Crashed in Release
The fix passed review. It still crashed in release. The reviewer was never tested. The reviewer was me. And an AI model. We both approved the same w…
The Coverage Loop: Turning Free AI Tokens into Verified C++ Tests
Unit tests are boring. Coverage is not optional. I asked a free AI model to write my tests. It failed. Then I built a feedback loop. Here is the res…
Beyond OOP: Entity Component System schema for high performance
Object-Oriented Programming (OOP) taught a generation of software engineers to model complex domains by creating class hierarchies. In games and rea…
Design Notes for a Deterministic C++ Simulation Framework
“Same inputs, same result” sounds like a simple requirement. In a multithreaded simulation, it is an architectural constraint that touches data layo…
Target Data in GAS
What is target data and why should you use it Target data is an ability task in GAS used for sending certain data to and from the server. It's used…
Fast & Lightweight Online CRC Calculator

I got tired of paying to emulate a 1970s terminal, so I built a native macOS client in C++ (DX3270)
If you work with IBM Mainframes (z/OS, z/VM) on a Mac, you’ve probably noticed a glaring issue: every halfway-decent TN3270 terminal client costs mo…
Creating a Custom Grid Editor tool in Unreal Engine
Hello there, Dev community! I'm a beginner, relatively, in the Game Development / Programming sphere. I'm a second year student as of writing this b…
cpp-linter-hooks: The Most Complete pre-commit Solution for C/C++ Projects
If you work on Python projects, you've probably used pre-commit — running black , ruff , mypy before every git commit , blocking anything that doesn…
Recovering Corrupted ROS 2 Bags Without a ROS 2 Runtime
