Pandora

“And then in Spotify, it just seems just effortless. But it helped me discover all kinds of artists I never would have discovered otherwise. And Pandora, I used a lot. Pandora is more prioritizing on the discovery part versus organization part. And that was really wonderful.”

SQL

“Yeah, but I should say, I personally love SQL, because I’m an algorithms person, so I love optimization, I love to know how the databases actually work, so I can match the SQL queries and the design of the tables such that there is optimal… Squeeze the optimal performance out of the table.”

book / recommends

The Glass Bead Game

“and The Glass Bead Game if you want to take on Hesse’s magnum opus, that rigorously explores the ways the human mind and human civilization can engage in the pursuit of knowledge, wisdom, and meaning. But Siddhartha is the only one I’ve returned to more than twice. In my own life, when faced with a difficult situation, I often return to the moment in the book when Siddhartha is asked what skills he possesses, and his answer is simply, “I can think, I can wait, I can fast.” Let me elaborate. Indeed, for the first part, “I can think.” As Marcus Aurelius said, “The quality of your life is determined by the quality of your thoughts.” For the second part, “I can wait.” Patience and waiting often is indeed the optimal decision when facing a problem. Time does bring clarity and depth of understanding. For the third part, “I can fast.” When needed, being able to live and flourish with less is a prerequisite of being free when the mind, the body, and society all are trying to put you in cages. All right, friends, now sadly, our time together in this episode has come to a close. As always, thank you for being here and thank you for your support through the years. Let me leave you with a few words from the Bhagavad Gita. “He who experiences the unity of life, sees his own self in all beings and all beings in his own self and looks unto everything with an impartial eye.” Thank you for listening. I hope to see you next time.”

If you go to the physics department and the biology department, those people are different in some categorical way. So somehow, I don’t know what the chicken or the egg is, but the categories… Maybe the categories create themselves because of the way we think about them and use them in language, but it does seem useful.
