The Rundown for December 12, 2022

• How to decode credit card numbers.

• Ex libris - the book plates of famous writers. This almost makes me regret foregoing physical books. Then I remember I have my library everywhere I need to read.

• A list of powerful “decision razors” - “A “razor” is a rule of thumb that simplifies decision making."

• Bruce Schneier on Regulating DAO’s: “Tying free speech arguments to the cause of DAOs like Tornado Cash imperils some of the important free speech victories that were won in the past. But the risks for everyone might be even greater if that argument wins. A world where democratic governments are unable to enforce their laws is not a world where civic spaces or civil liberties will thrive.”

• Fermi paradox explained through other civilizational endgames: collapse or homeostasis.

We propose a new resolution to the Fermi paradox: civilizations either collapse from burnout or redirect themselves to prioritizing homeostasis, a state where cosmic expansion is no longer a goal, making them difficult to detect remotely.
