Thanks to this bussin new #rstats 📦 by @hadley.nz, you can now yeet rows and vibe_check columns in your data frames, no cap hadley.github.io/genzplyr/

Some noted that the BEV ranges in my article were unadjusted (China's CLTC cycle over-estimates range compared to the U.S.'s EPA cycle). So I now have an interactive app that allows you to explore how the main scatterplot looks with an adjustment factor: jhelvy.github.io/science-2025/

🚗⚡ New in @science.org: My piece on why the U.S. needs to rethink its approach to China's electric vehicle industry (and what's at stake if it doesn’t). The competitive gap is bigger than you think. Thread 🧵 www.science.org/doi/10.1126/...

When the data tells a clear story, we all make the same chart 📊 Left: From @hannahritchie.bsky.social's ourworldindata piece (Oct 24, 2025) on EV sales: ourworldindata.org/electric-car... Right: a slide from a talk I gave at Princeton in Feb. 2025 jhelvy.github.io/slides-old/2...

As an #rstats user, I am proud of my #python brothers and sisters for standing up for their community. It's a shame they won't have these resources, but community is and always has been what makes a language great. Today the python world stood up for theirs pyfound.blogspot.com/2025/10/NSF-...

My controversial take on K-pop demon hunters: "Free" is the best song on the soundtrack youtu.be/fjOeJssZX_Q?...

This is an exceptional article. @kaiserkuo.bsky.social puts in words thoughts I've had for years about the intellectual challenge the west faces in reckoning with China's success, not just in modernizing but in some critical areas leading, while historical leaders remain unaware they no longer lead.

You should read this wonderful little history of the #tidyverse, by @hadley.nz. It reminded me about my early #rstats days as a PhD student (2011 - 2016), where I was constantly trying out the new things Hadley and crew were cooking up. hadley.github.io/25-tidyverse...

"Golden" is going to go down as the "Queen of the Night" aria of our time

You beat authoritarians by sticking together

Heartbreaking loss...GM Daniel Naroditsky, just 29 year old. Not just a genius chess player, but a huge personality and amazing human being. www.chess.com/news/view/gr...

Truly an amazing work. If you like #dataviz and good story telling, this is quite an achievement.

Vought is the true wanna be king in this administration - a Cristian Nationalist bent on destroying as many institutions as possible to consolidate his power. Little Don and Elon are just his play things. www.propublica.org/article/russ...

Happy Sic Semper Tyrannis Day!

Actually it's worse than that. Most of the energy expended by a (gas) car is exhausted as waste heat, then most of the *remaining* energy is spent on moving the weight of the car.

I knew MIT hired smart people www.nytimes.com/2025/10/10/u...

#Rstats, #python, #julialang

The south park satire of ICE is not satire.

Great article in Newsweek by Rebecca Fannin on the dominant position of Chinese EVs globally and the implications for the future of automotive and defense. Well-researched article with quotes from me, Paul S. Triolo, Michael Dunne, Kara Kockelman, and others. www.newsweek.com/chinas-ev-su...

U.S. Dept. of Energy Office of Energy Efficiency and Renewable Energy banned from using words like "climate change" or "emissions"...you know, phrases that have nothing to do with things like energy efficiency or renewable energy 🤦‍♂️ www.politico.com/news/2025/09...

Doing harm to universities and science is the point

He would still be working for ICE if he was wearing a mask in this video

Looks like we'll just have to watch Bluey on YouTube from now on

$40k for an EV with just 216 miles of range does not even qualify as "average" imo. That's a very tough sell in a market where you can get a similar gas car for at least $10k less. Make that same EV for $25k and it'll sell like crazy, even if it had the interior of a Corolla.

For those at #positconf I'll be presenting this in one hour in Regency VII! surveydown.org

The GOAT RStudio addin by @milesmcbain.bsky.social

The man did not deserve to be murdered, but no, he did not practice politics the "right way" @ezrakleinbot.bsky.social. Calling your opponents cockroaches and saying gay people should be stoned is exactly the kind of dehumanizing language that leads to violence and should be condemned, not envied.

Political violence of all kinds is wrong, criminal, and must be condemned, regardless if it is committed against an inspirational and honorable lawmaker from Minnesota or a far-right activist who believed that having some "unfortunate" gun deaths each year is worth it for the 2nd amendment

One week til I present on our survey platform surveydown at #positconf! If you've ever wanted a #Quarto for surveys, this is it! 🚀 #rstats surveydown.org

I'm no political strategist, but I'd say the illegal occupations of our cities are rather unpopular. The Dems once again will have an opportunity to say something about that: end the occupations, or we shut the government down. But I also expect that they will, again, cave.

Very cool to see surveydown in RDM Weekly!

Excited to announce that our paper with @pingfanhu.bsky.social and Bogdan Bunea on our #rstats package {surveydown} is now published in @plosone.org The paper compares the benefits of using a code-based approach to survey design, leveraging #quarto and #shiny journals.plos.org/plosone/arti...

Seems bad

Whole lotta tiki torch energy from this one

If cheating on your wife is cause for being sacked as CEO, then why in hell is Musk still CEO of Tesla? Cheating is bad, but single-handedly destroying a humanitarian agency that will lead to the deaths of millions of children seems...worse. Make it make sense.

If you use #tidyverse / dplyr, breakerofchains by @milesmcbain.bsky.social is one of my favorite productivity #rstats 📦 Very excited to learn that it works in #positron too! One more reason to keep using this IDE, absolutely loving it forum.posit.co/t/breakerofc...

This is a very good talk by @karpathy.bsky.social on where we're at with LLMs for software development www.youtube.com/watch?v=LCEm...

Excited to announce the release of our latest #surveydown project: {sdstudio} A GUI studio that runs as a local #rshiny app for building, previewing, and managing surveydown surveys. Check out our latest post! 📣 Should out to @pingfanhu.bsky.social who built it! surveydown.org/blog/2025-06...

The bill that just passed is devastating, esp for rural America. Millions will lose healthcare access entirely. Hundreds of rural hospitals will close. Electricity prices will rise, grid stability will worsen. ICE's budget is now larger than FBI & DEA combined. Masked kidnappings are just the start.

Not 👏 all 👏 research 👏 needs 👏 to 👏 be 👏 causal I swear, someone needs to start a new journal called "Descriptive Research" or something where editors filter explicitly for descriptive, non-causal research. And yes, non-causal descriptive research can be used to inform policy!

The energy provisions in the Republicans' One Big Horrible Bill are truly so bad! Who wants this? The country's automakers don't want it. Electric utilities don't want it. Data center developers don't want it. Manufacturers in energy intensive industries don't want it. 🔌💡

Destroy jobs, raise energy costs, obliterate trust in the business community, and add at least $3T to the national debt, all so we can give billionaires even more 💰

Legal people, based on the SCOTUS decision on universal injunctions, am I right that if a future president bans assault rifles and someone sues and wins in a lower court, the ruling only affects that one person? Like, the president could seize guns and nobody could stop it unless it got to SCOTUS?

Spot on

Claude writes #rstats code like it's python. It loves for loops and seems incapable of understanding vectorized operations, matrix math, etc. It ignores all the efficient ways of doing things in R. Great for simple tasks, but I'm running into limits.

I understood this post because I listened to @jessedjenkins.com's episode on shift key about it, which to this day is imo one of the best and most approachable explanations of how the grid works (with also good commentary on the causes of the Iberian blackout) heatmap.news/podcast/shif...

IMO the most unrealistic aspect of the AI 2027 predictions is the assumption of a reasonably competent / remotely informed White House. I suppose I can't fault the authors if they wrote this before Nov 2024. ai-2027.com

Bro you can build your own keyboard with the same or better build quality and WAY more features for like $200. For another $100 you can have someone build it for you. www.jhelvy.com/blog/2021-07...
