I still teach from this book. It rules.

that's interesting I didn't realize you could still get shingles if you had an attenuated vaccine.

I had chickenpox and then shingles a couple years ago. worst physical pain I've ever had.

tbh there's no "best" AI. I think using cursor for scripting with claude code and gemini as terminal options works well right now.

I write spec docs with sonnet 3.7, architectures with gemini, and code with a combo of models. models have different strong suits.

Feel like there are a lot of folks on Bluesky who need to read this paper.

With rent control in the news, it’s a good moment to recall the research of @rebeccadiamond.bsky.social and co-authors.

They show that strict rent control in San Francisco reduced the availability of rental housing, eventually *raising* rental costs.

Common AI failure mode is to ask it for what you want in the end. One day that’ll be doable generally… only sometimes it works now.

For now ask for code that generates what you want (where applicable).

This is true for training ML models too… learn the DGP then transfer to other target/outcome.

Point is...
1. Don't trust AI to run even the most basic statistical things (yes, yes I knew that already, but then you get told you must use this stuff, and then...).

2. Don't rush to post things to social media, it creates dumb and embarrassing situations like this one.

It was always a better platform for building.

One thing I love now is being able to implement papers on my own at low cost.

This is a common phenomenon that's not unique to this site. As a reporter, I post things about antisemitism in America as part of my job. The posts do not mention Israel. I will nonetheless get many reflexive replies saying "anti-Zionism is not antisemitism." These people are telling on themselves.

This is a post from a Jewish politician condemning rising antisemitism in the US, saying nothing about anti-Zionism or Israel. And yet the replies are entirely full of people preemptively jumping in to say, “criticizing Israel is not antisemitism! Being anti-Zionist is not antisemitic!”

Today marks the end of Jewish American Heritage Month, Illinois.

I won't be silent in the face of a continuing record rise of antisemitism in our nation.

There is strength in our faith, and we can always find strength in one another.

Full automation of code is a choice, and I don’t think it’s one that’ll be made in most firms. By percentage of code written, sure, machines will dominate. but you know what’s complementary to shitloads of new code? Talented developers.

Again, I don't think it's at all obvious what AI is going to do to the economy but on my very specific hobby horse: it's darkly funny how quickly we've gone from "mobilize schools to meet the economy's unfathomable appetite for computer scientists" to "tough luck coders we have AI now".

EXCLUSIVE: Anthropic CEO Dario Amodei has a blunt, scary warning: AI could wipe out half of entry-level white-collar jobs and spike unemployment to 10-20% in the next 1-5 years.

Few are paying attention: Politicians don't get it. CEOs are afraid to talk about it.

For those who don't know this story, which I first shared six years ago today....

This one time I got my days wrong at work and ended up alone in a room with my boss and the President of Ireland while I was on ketamine.

It also strikes me as somewhat bad faith to attack Koch or Arnold here.

People don’t realize the reason bond ratings matter is that they’re tied to regulations and policies with margining requirements.

You really don’t want the BBB- to BB+ change.

(Bloomberg) - Hong Kong’s pension fund managers have flagged the risk of potential forced selling on their Treasury holdings after a downgrade by Moody’s Ratings of US debt, according to people familiar with the matter.
