Desktop vs embedded Memes

Going from desktop development to embedded systems is like moving from a mansion to a studio apartment where you have to choose between a bed and a toilet. Your RTX4090-powered beast casually throws around 4GB textures like it's pocket change, meanwhile your ESP32 is having an existential crisis trying to display a 16-color bitmap. The ESP32-S3 typically has around 512KB of SRAM and maybe 8MB of external PSRAM if you're lucky. That's not a typo—kilobytes and megabytes, not gigabytes. Suddenly you're counting bytes like a depression-era accountant, optimizing every malloc, and questioning whether you really need that string or if a single char will do. Welcome to embedded, where "running out of memory" isn't a meme, it's your daily standup update.
