Great example of using R for efficient, LLM-enabled data science (by Hadley Wickham)

What's the easiest supposedly hard thing?

Can you think of a movie where the protagonist lives in a 5 over 1?

So I'm walking down the sidewalk near my apartment and I see this big stash of plywood being thrown out. I'm some distance away but I can tell it's beautiful stuff. Very straight, many plys. 1/3

Is it me or does saying six-digit verification codes to yourself make them easier to remember for the five seconds you need them?

My 12-year-old has a future in pop science journalism

Kind of excited for improv theater to come back and satisfy an impending craving for non-AI-generated fiction

No one talks about how the global epidemiologist population went from 3 billion to 30,000 in the period from 2020 to 2026

I would sign up for the Chase Sapphire Rewards card again because it felt so good to cancel it last time

"If it had been STATA, I wouldn't have felt a thing. I'd be dead." What movie?

Classical economics: 98% of the data is easily explained by one theory Behavioral economics: 2% of the data is easily explained by sixteen theories

can mathematical economics explain this hardcover premium?

Airplane designer 1: How can we position the outlet so a phone charger has the greatest chance of falling out? Designer 2: On the ceiling Designer 1: But then it's too easy to see Designer 2: Downward at an angle? Designer 1: Perfect!

Review of Boston based on my 2 day visit: Sailboats ✅ 60⁰ weather ✅ Brick sidewalks ✅ Coach lanterns ✅ Someone solved the exceedingly difficult graph theory problem I left on the hallway chalkboard overnight ✅

Clever thing they do in Boston: They make the bus to the airport seem like a train. You transfer from the train. It looks like it's running on train tracks. Addresses that whole "oh no I don't want to transfer to a bus" anxiety.

not only are they selling a bagel, lox, and juice for $25 but they're putting it in the window like look at this deal! get in here!

Every system or con that depends on the argument "nobody's going to take the time to do that" is going away. AI will take the time to do that.

My dad inherited my grandfather's tools. They seem to have accumulated screwdrivers at the rate of 1 per 6 years.

Beach glass is just pollution with good branding

We saw this knot on the sidewalk in Little Tokyo, Los Angeles and tied it at home. Carrick bend, apparently.

Minecraft OSHA violation

And, more generally, we applied consistent terminology: * Reproducibility = same data, same analysis * Robustness = same data, different analyses * Replicability = same question, different data These are examples of repeatability, and are components of the broader concept of credibility.

You have a data set and you torture it until it confesses a publishable story. You literally run loops testing millions of assumptions, exclusions, and model specifications. You end up in a subspace where things look pretty robust but this subspace is just 5% of reasonable analyses.

Nature meta-research project puts claims in social-science paper to the test. Refs in last post I'm interested in Econ and Psych so I focused on that: Econ had about the same rate of "not reproducible" analyses as Psych and a worse rate then Political Science.

My friend took the anti-drunk-driving animation I coded in BASIC when I was 14 and put it online! Good old drunk.bas !

I was introduced to Apple by learning BASIC on a IIe when I was 7. So, this morning, I thought I’d write a little “Happy Birthday, Apple” program in BASIC. But there's no basic interpreter for the Mac! So I Apple dorked all the way out and wrote one for my 7-year-old. github.com/jpurnell/App...

Talking to some undergrads tomorrow about the why no one actually pays us to type model.fit() and asked them ahead of time to submit answers to a "trivially easy" data problem Fun to see the results come it, wild to know how many business run with a not dissimilar fog of war

My bank texted me a code and then rejected it as incorrect and I was like look I'm just trying to be helpful and if you know the code then why are you asking me?
