performance

Definition

How fast and efficiently your code runs, measured in metrics that will definitely be scrutinized when things slow down. It's the difference between your app responding instantly and users having time to make coffee while waiting for a page to load. Developers obsess over performance optimization until they realize premature optimization is the root of all evil.

Example Usage

The app's performance tanked after we added that fancy animation, and now users are threatening to switch to our competitor.

authentication

The security process of proving you are who you claim to be, typically through passwords, biometrics, or sacrificing your firstborn to the security gods. It's the digital handshake that happens before a system trusts you enough to let you in, usually involving at least three wrong password attempts. Not to be confused with authorization, which is what happens after authentication and determines what you're actually allowed to do.
