Tracking Global Vaccination Rates with Docker, Python, and IoT
I’m a major fan of the ESP32-S2 platform of low-power, low-cost, Wi-Fi capable microcontrollers.

The Impacts of an Insecure Software Supply Chain
Today, software regularly integrates open-source code from third-party sources into applications. While this practice empowers developers to create more capable software in a shorter time frame, it brings with it the risk of introducing inadequately vetted code.
