They go over big O and data structures, Jason and Safia have a vulcan mind meld over Timsort, and Adam almost went down a rabbit trail of YouTube videos.

The hosts talk about various types of machines from finite-state machines, pushdown machines, and turing machines, and then get distracted by retro computing and the turbo button.

Adam and Jen have new jobs, they talk about complexity in the real world vs academia, and then Safia and Adam get some real-time learning in lambda calculus.

They talk about the first chapter, their computer science backgrounds, genetic algorithms, Star Trek, their first computers, and what they're looking forward to in the book.

We talk with Sara about why she wrote the book and some of her thoughts about how to change the industry.

We get into a lively discussion about sexism and racism in the workplace and the interview process, and Safia puts Adam and Jason in the hot seat.
