node

Definition

A connection point in any network—whether it's a lymph node in your body, a server in a computer network, or a decision point in a data structure. In tech, it's basically any device or data point that's part of a larger system, from your laptop hogging bandwidth to a single element in a blockchain. Nodes are where the action happens, data flows through, and things can go gloriously wrong.

Example Usage

The network went down because someone accidentally unplugged the primary node, which turned out to be Kevin's desktop under his standing desk.

velocity

In the startup world, the speed at which your development team can actually ship features, measured in story points or whatever agile metric your project manager is obsessed with this quarter. Unlike regular speed, velocity has direction—ideally forward, though some teams seem to excel at moving sideways. It's the number that determines whether you'll make your demo day deadline or spend the weekend surviving on Red Bull and regret.

horizontal scaling

Adding more servers to distribute load rather than making existing servers more powerful. It's the 'hire more workers' approach versus the 'give workers steroids' approach, and generally works better at internet scale.

environment

In tech, the specific setup where your code runs, complete with its own configuration, dependencies, and personality disorders. You'll typically juggle development, staging, and production environments—each one guaranteed to behave differently despite being "identical." The infamous phrase "but it works on my environment" is every developer's defensive battle cry.

Neural Network

A computing system inspired by the human brain, except it requires millions of dollars in hardware and still can't tell if a photo contains a dog or a muffin with 100 percent accuracy. It learns from data the way a toddler learns from experience -- chaotically and with frequent errors.

horsepower

A delightfully archaic unit of measurement that literally compares your engine to how many horses it would take to do the same work. Invented by James Watt to market his steam engines (seriously), one horsepower equals about 746 watts, though the metric version differs just to keep things confusing. Car bros still use this to measure their vehicle's masculinity.

Syntax

The grammatical rules of a programming language that determine whether your code runs beautifully or explodes because you forgot a semicolon. Syntax errors are the typos of the programming world -- small, embarrassing, and responsible for 90 percent of your debugging time.
