We've all done it. You commit a .env file by accident, catch it a few commits later, delete it, and breathe a sigh of relief. Except... it's not gone. It's still sitting in your Git history, one git log -p away from anyone who clones the repo. That'...

The Xbox wrote 8 GiB of persistent data. I still couldn't call the experiment successful. The bytes were there, but the operation failed because a completely different part of the system had timed out. In another test, the worker correctly refused ...

When developing flight software for spacecraft and rovers, standards are everything. NASA’s F Prime framework powers autonomous flight control and deep-space telemetry. While analyzing the CFDP CCSDS File Delivery Protocol implementation inside F Pr...

A lot of C/C++ developers build complex data structures as if database theory never happened. And then they spend months maintaining pointer contracts that a schema could have made obvious. Let’s take a graph structure as an example. A common patte...

I thought embedding a web UI into a native desktop application would be the easy part. After all... macOS has WebKit. Linux has GTK WebKit. Windows has WebView2. One API per platform, smaller installers, native look & feel. Sounds perfect. Then real...

1. Why build another multi-tool? How many of you have often found yourselves wanting to buy a Flipper Zero? I thought about it many times, but there were always problems holding me back: stock is often limited, the price tag is quite high, and abov...

Generic C++ code needs customization points whenever a library wants to operate on types it doesn't own. The problem is deceptively simple: how can a library let users customize an operation without requiring inheritance, runtime dispatch, or modific...

In C++, a default constructor is a constructor that is automatically created by the compiler if no other constructors have been defined for a class. However, if a class has any constructors that have been explicitly defined, the compiler will not cr...
