Episode notes
Asciinema's Origin
- Marcin Kulik built Asciinema because he was fascinated by the "magical" script command and wanted to share recordings.
- The initial prototype used jQuery to replay terminal sessions within a div element on a webpage.
Text-Based, Not Video

- This approach captures the essence of the information with less bandwidth.
Emulator at Heart
