    Tonight i had the weirdest dream of seeing @antirez and @badlogicgames playing tennis table and they were too damn good! πŸ™ˆ What do I make of this? Either I like software (and some of the influential people around it) way too much, or I need to see a shrink... Or probably both!

    Environment variables in Node.js look trivial until they bite you: everything is a string, "false" is truthy, and every child process you spawn inherits your secrets. I just published a complete guide. Here's the short version 🧡
    Infographic titled β€œNode.js Environment Variables: Simple until they bite you.” On a dark, neon green and cyan tech-style background, five panels explain key pitfalls and best practices: (1) everything in process.env is a string, for example PORT becomes "3000"; (2) the β€œfalse” trap, where "false" is still truthy in JavaScript; (3) built-in .env loading in modern Node.js with --env-file; (4) layered .env files, where later files win but OS environment variables still override; and (5) security risks, showing child processes inheriting secrets by default. A green banner at the bottom highlights the best practice: use one validated config module, fail fast, and keep secrets out of environment variables in production. The full guide URL appears at the bottom: nodejsdesignpatterns.com/blog/nodejs-environment-variables.
