Interior of the Bodleian Library in Oxford, showing historic wooden bookcases and a decorated ceiling. In the foreground, a sign displays the traditional Bodleian Oath, which readers must read aloud before being admitted to use the library.

The oath reads: 'I hereby undertake not to remove from the Library, or to mark, deface, or injure in any way, any volume, document, or other object belonging to it or in its custody; not to bring into the Library or kindle therein any fire or flame, and not to smoke in the Library; and I promise to obey all rules of the Library'

1. A short thread on a Bluesky phenomenon that might be described as "They are a dead-eyed cultist who must be cast out lest the heresy take root!" OP has blocked me for mocking them - I'd usually obscure their name but since they themselves were quote-dunking to demand someone else be blocked ...

We will be pluralistic about ratios and about shaking/stirring. Very forgiving, honestly.

Not sure about the Martinez. Maybe there will be a dessert menu.

No science allowed until one has had at least two martinis.

If anyone asks or a vodka martini, they will be given the option of a Vesper or they can be escorted out.

Smoky martinis, woody martinis, citrusy martinis, so many more. Just by varying the gin, the vermouth, the garnish, and maybe a dash of bitters here and there.

Mineral water available for the teetotalers, but only served in a martini glass. 🍸

Thinking of opening a martini bar after I retire. Various nibbles will be served, but all of the drinks will be martinis. Real martinis: gin, vermouth, garnish. But there will be dozens of different versions available.

DAY TWO of an experiment where I wake up and do a take/video without paying β€œthe woman tax” of doing my hair and make-up. Like/follow/comment/subscribe if you’re into normalizing women looking unkept while doing political commentary.

Laws of Nature and Chances: What Breathes Fire into the Equations This book’s subtitle is based on a question the physicist Stephen Hawking once asked: “What breathes fire into the equations…?”...

Craig Callender, the unreformable Humean, reviews Loewer’s book with lots of cooking and home improvement metaphors. Both delightful and informative #philsci #philsky

Computer Professionals for Social Responsibility - Wikipedia

Back in the 1980s-2000s, there was an organization called
Computer Professionals for Social Responsibility that worked to oppose irresponsible and dangerous uses of computers in warfare. Maybe it needs a reboot, in our new age of AI.

Well, it wasn't only that the administration was demanding that they be able to use the AI models to autonomously kill people; they also want to use AI to assemble and deploy a comprehensive surveillance database on the behavior of all Americans. What's to worry about?

Reminiscent of the many times someone has asked an LLM β€œdid our government really just do this?” and the LLM replied β€œhaha, of course not, there’s no way,” only to come back after prodding with β€œoh, apparently they did.”

Really good talk by Doug, who thinks like a physicist but gives valuable insight into how people in the AI world are thinking.
