Null Memes

Finally, a visual representation that my brain can process! Zero is an empty toilet paper roll that still exists and serves as a placeholder. Meanwhile, NULL is when the entire roll is missing—it's not just empty, it's gone , non-existent, undefined. The cardboard tube has left the building. This is exactly what keeps junior devs up at night. Zero is a legitimate value saying "there's nothing here, but I'm counting it." NULL screams "I refuse to acknowledge this variable's existence." And both will break your code in spectacularly different ways when you least expect it.

Looks like someone forgot to handle their price exceptions in production. That electronic shelf label is just screaming "null null" where a price should be - the digital equivalent of a store clerk throwing their hands up and saying "I have no freaking idea what this costs anymore." Even the database is feeling the economic crisis. Can't afford to store actual values these days, just pointers to nothing. Somewhere a backend developer is getting a frantic call while pretending they didn't see the Slack notification.
