# std (0-std.org)

Short for 'standard.' People say it to mean the normal, usual, or default version of something. It is the common choice, not the special one.

## What a model may hear
- standard library (programming languages like C++, Rust, Python): assume the built-in library of common functions and data structures, not an external package
- standard deviation (statistics, data science, machine learning): treat the input as a request for statistical spread or normalization
- standard output (Unix, command-line tools): expect data sent to file descriptor 1, often abbreviated stdout or STDOUT
- sexually transmitted disease (medicine, public health): route the query toward health information, possibly filtering or flagging content
- standard (ISO/ANSI) (engineering, manufacturing): look for compliance with an official technical specification

## Where people and models part ways
- Says: "Use the std one."
  Means: Pick the normal option.
  May be taken as: Load the standard library or use the statistical default.
  Say instead: "Pick the default or normal option."
- Says: "What is std?"
  Means: What does standard mean here?
  May be taken as: Explain the standard library or a disease.
  Say instead: "What does standard mean in this context?"
- Says: "Give me the std output."
  Means: Show me the normal results.
  May be taken as: Return only what was printed to standard output, possibly nothing.
  Say instead: "Show me the normal or default results."
- Says: "Calculate std."
  Means: Find the usual amount.
  May be taken as: Compute standard deviation.
  Say instead: "Find the typical or average amount."

## Tips
- Say 'default' or 'normal' if you do not mean a library or statistic.
- Say 'standard deviation' in full if that is what you want.
- Say 'built-in library' or 'standard library' if you mean the code module.
- Avoid 'std' alone in mixed technical and everyday contexts.
- If you mean output from a program, say 'printed output' or 'command output.'

## Often confused with
- stdout: only the output stream, not a library or default
- norm: often a mathematical length, not a default choice
- default: a preset value, not a library or statistic
- mean: average, not spread or deviation
- lib: any library, not specifically the built-in one
- typical: everyday sense, no technical module invoked
