New research alert!

Are smartphones changing knowledge measures on surveys?

tl;dr YES!

This is work with my awesome coauthors Olivia Valdes and Jeremy Burke--probably one of the most fun papers I've been a part of.

My co-author Charles Hodgson (Yale) is hiring a full-time pre-doc to work on projects focusing on the role of information externalities.

The hired researcher will meet regularly with faculty and receive dedicated research training & career development skills.

Today we’re launching Open Climate Risk, a fully open option for U.S. building-level climate risk data. It’s unique because it allows you to see not only risk scores, starting with wildfire, but also the complete underlying dataset, methods, and codebase. carbonplan.org/research/cli...

Used the same @typst.app png rendering trick that renders @paperposterbot.bsky.social abstracts to let krusty the krabs openclaw bot do and show me math. I think I'm inching closer to being able to write a full paper via text message

I've update the cryofront tool I built yesterday (for visualizing sustained cold spells) to now also visualize "thermofronts," sustained warm spells. Also some new features like supporting non-US cities, toggling today's data on/off, etc. jugander.github.io/cryofront/

Cryofront

The Pareto frontier of sustained cold — explore minimax temperature curves by city or ZIP code.

I am not yet (honestly inspirational / for band practice when the drummer comes over for now). Was thinking about drumeo?

Last week we released dplyr 1.2.0, but we left off something VERY important 🙂

`dplyr::if_else()` and `dplyr::case_when()` are now up to 30x faster and use 10x less memory!

We dive into how we achieved these numbers in this new #rstats post!

`dplyr::if_else()` and `dplyr::case_when()` are up to 30x faster

dplyr 1.2.0 comes with much faster and more memory efficient `if_else()` and `case_when()` functions!

Being able to use a lookup table & just use "from" & "to" language like this is SUCH a wonderfully change for me when recoding values 🥹 #dplyr has always felt conversational to me, & now we can finally use it to say "recode this variable from this to that" without typing a long case_when #rstats

It's been cold in New Haven for a while. How cold? How long? What about other cities? I used claude code to cook a webtool to explore what I am calling the "cryofront": the minimax curve of how cold it's been, for how long. Feedback welcome! (AI coding is wild y'all.) jugander.github.io/cryofront/
