validation

Beginner 💻 Tech / IT

Definition

The process of checking whether data actually makes sense before letting it wreak havoc in your system—like a bouncer for your database. In tech, it's the gatekeeping function that prevents users from entering "banana" as their birth date. In therapy-speak, it's getting someone to acknowledge your feelings, but programmers prefer the database version.

Example Usage

Our form validation caught 47 people trying to register with email addresses that were just variations of curse words.

compandor

A device that compresses audio signals before transmission and expands them after reception, reducing noise and improving signal quality over long distances. This portmanteau of 'compressor' and 'expandor' was crucial in early telecommunications, squishing signals down for efficient transmission then puffing them back up on the other end. It's audio engineering's version of vacuum-packing your voice for shipping.

var

In tech-speak, a unit of reactive electrical power, but more commonly recognized as the keyword that lets programmers declare variables without overthinking what type they should be. VAR also moonlights as "Video Assistant Referee" in sports, proving that three letters can mean entirely different things depending on whether you're debugging code or disputing an offside call. The chameleon of acronyms.

query

A formal question posed to a database or search engine, written in special syntax because apparently "please find me all customers in California" is too simple. In tech contexts, it's the structured request that retrieves data—when it works—or returns cryptic error messages when you forget a semicolon. Outside databases, it's just a fancy word for asking questions, preferred by people who think "inquiry" sounds too casual.

bikeshedding

Wasting time on trivial details while ignoring important issues, like spending three hours debating button colors instead of addressing the security vulnerability. Named after committees spending more time on the bikeshed than the nuclear reactor.

requirements

The supposedly clear specifications of what a system, project, or product must do, which somehow always turn out to be neither clear nor complete when development begins. In tech, they're the sacred documents that stakeholders change weekly while insisting nothing has changed. The gap between what's written and what's actually wanted could swallow entire development teams.

Conway's Law

The observation that organizations design systems that mirror their communication structure. If your company has four teams, you'll build four subsystems—whether that makes sense or not.
