### Transcription scheme ### Lines starting with `%` are comments, most often used for interspersed time codes. We use the following notational conventions: [...] : omissions in the transcript (~) : unintelligible word or words (..) : pauses, one dot per second (,,) : silent computer interaction, one comma per second (#main#) : reading aloud from screen (##return false##) : speaking while writing (!...!) : self-interruption, the speaker stops mid-utterance (!!...!!) : the speaker is stopped by the partner (!!Yeah!!) : the partner interjects something <*read source code*> : the person performs an action : paraverbal utterance <**lead developer**> : blinded for anonymization
