## What people usually mean

A har is a harsh or unpleasant sound, like a sharp laugh or a grating noise. People might say it to imitate a sarcastic chuckle or a rough vocal sound.

## Senses you may read into it

Use one of these only when the conversation is already in that field.

- HTTP Archive format (web development, browser DevTools, networking): assume the user wants to create, parse, or analyze a .har file containing recorded HTTP request/response data
- harmonic mean or ratio (statistics, signal processing, audio engineering): calculate a harmonic average or interpret as a frequency-related measurement
- hardware abstraction register (low-level systems programming, embedded systems): reference a memory-mapped register or hardware interface
- HAR model (heterogeneous autoregressive) (econometrics, financial time series): apply a volatility forecasting model using realized variance at different sampling frequencies

## When a person says

- "save my har"
  They mean: remember this unpleasant sound I described

  Read it as: "save a description of this harsh sound I told you about"
- "analyze the har"

  Avoid: parse and inspect HTTP archive data for performance metrics
  Read it as: "analyze the harshness of the sound I described"
- "find the har"
  They mean: locate an example of this rough vocalization
  Avoid: search for a .har file or attempt to generate HTTP archive data
