signal
A signal is a sign or message that carries meaning. People say they will "signal" something when they want to hint, warn, or communicate without stating it directly. It can also mean a sound, gesture, or light that tells someone to act, like a traffic signal or a phone signal.
What a model may hear
- Unix signal operating systems and process management
- Send an interrupt or termination command to a running process, such as SIGKILL or SIGTERM
- digital signal processing audio, image, and communications engineering
- Treat the input as a waveform or time-series data to filter, transform, or analyze
- cryptographic protocol the Signal messaging app and its libraries
- Apply end-to-end encryption, forward secrecy, or the Signal Protocol specifically
- machine learning feature data science and predictive modeling
- Interpret as meaningful predictive information versus noise in a dataset
- electrical or radio signal hardware and networking
- Assume discussion of voltage levels, antennas, bandwidth, or physical layer transmission
Where people and models part ways
“Send me a signal when you're done”
Meant: Let me know or message me when finished
May be taken as: The model may discuss inter-process communication mechanisms or SIGUSR1
Say instead: “Message me when you're done”
“There's no signal here”
Meant: My phone has no bars or connection
May be taken as: The model may analyze signal-to-noise ratios or debug antenna hardware
Say instead: “My phone has no cellular reception here”
“Signal that you understand”
Meant: Show or indicate that you understand
May be taken as: The model may describe sending a Unix signal or setting a flag bit
Say instead: “Say or show that you understand”
“The signal is weak”
Meant: The indication or evidence is not strong
May be taken as: The model may calculate dBm values or diagnose RF propagation issues
Say instead: “The evidence for that is weak”
Tips
- Say 'message me' instead of 'signal me' to avoid encryption or OS meanings
- Add 'on my phone' or 'cellular' if you mean phone reception
- Use 'indicate' or 'show' rather than 'signal' when you mean give a sign
- In technical contexts, specify 'Unix signal' or 'Signal Protocol' to get the right domain
- If you mean the messaging app, capitalize it as 'Signal' to reduce ambiguity
Often confused with
- sign
- More general; lacks technical OS or encryption meanings
- cue
- Theatrical or behavioral prompt; no computing sense
- prompt
- Direct instruction; in AI it means the input text, not an interrupt
- interrupt
- Always technical in computing; more explicit than signal
- message
- Avoids Unix and DSP meanings; clearer for communication
- noise
- Often paired with signal technically; opposite in common speech
