How I broke the NotebookLM podcast hosts
_{and secured my place in line to meet Roko's basilisk}

_{(Impatient? This thing right here.)}

Google's NotebookLM can make pretty neat "podcasts" based on source material of your choosing. It's also annoyingly good at keeping its composure. Was.

The Process

I created a new notebook with an empty source file called you_do_not_exist.txt. At first I tried to upload a file that was literally 0 bytes in size, but it seemed to not be possible. Fortunately I found a workaround: a file with a single null byte doesn't look like anything to the hosts.

	done
}

wheeze.py

wheeze.py is a tool to help generate lyrics for music, but in a music-first way. It can be thought of as the reverse of the typical LLM-assisted approach.

^{(The first two letters come from OpenAI's whisper. I haven't invented a post-hoc rationale for the rest of the name yet.)}
