Elections have consequences

I can simulate fake data for you for a lot less $

More are writing on this, which is good. Now we need action. I propose strategic collaboration with leading firms, like we did in the past with Honda and Toyota. bsky.app/profile/jhel...

It's like they're making decisions in a protected market without exposure to Chinese competition or something

For a decade, the U.S. has debated EVs while China built an insurmountable industrial lead. In a new article for #NSB, John Helveston argues it is time for the US to adopt competitive policies. 🔗Read the full analysis: www.newsecuritybeat.org/2025/12/chin...

Wonderful news for the #rstats community! 🎉

I know this decision was made to intentionally make State Dept documents less accessible because having readble documents is woke or some nonsense, but NGL I kind of hate Calibri www.nytimes.com/2025/12/09/u...

When I wrote about the technology gap in EVs between China and the US in @science.org, a lot of people emailed me suggesting I was exaggerating. x.com/i/status/199...

Let's say you have a doctoral student who's a talented programmer but needs an introduction to the foundations of modern ML for a research project. What's the best open source resource for teaching themselves the basics in #python? Assume familiarity with things like pandas.

This is super interesting. I had no idea Haskell had these features, but the arguments are pretty solid for using Haskell for data science

PODCAST: China now sets the global EV pace. What does U.S. retreat mean for innovation, jobs, and industry leadership? John Helveston (@jhelvy.bsky.social) of George Washington University explains on the Energy Policy Now podcast.

I had a great conversation with Andy Stone on the Energy Policy Now podcast hosted by @kleinmanenergy.bsky.social on what's at stake for the US as China leads the world transition to EVs kleinmanenergy.upenn.edu/commentary/p...

NREL is dead, long live...NLOR? www.nrel.gov/news/detail/...

Online survey research is screwed. LLM-enabled agents can take surveys just like humans. Here's a video I made where the Comet browser agent takes a simple survey and gets around nearly all my bot detection checks. The crisis is here already...more in this 🧵 www.youtube.com/watch?v=05Je...

Yeah this is pretty accurate now. I've had ups & downs using LLMs for #rstats package development, but with Claude code in Positron it's just gotten amazing over the past year. At this point if I don't have an internet connection I won't even start a task because I know I'll solve it faster with AI

🎉 Announcing surveydown v1.0.0! surveydown is an #opensource #rstats package for building surveys with #Quarto & #Shiny. This release improves the survey design experience, including: - Simplified YAML settings - Auto page navigation - Previous buttons! More at surveydown.org/blog/2025-11...

Definitely a great way to exude more seriousness is to change the name from "Loan Program Office" to "Energy Dominance Finance" I mean for sure it's just so super serious www.eenews.net/articles/wri...

This will destroy US Science

My talk from #positconf 2025 is now up! I got to introduce our survey platform and #rstats package #surveydown. It's been a fun project with @pingfanhu.bsky.social & Bogdan Bunea, and I hope it can be useful for the community of survey researchers out there! www.youtube.com/watch?v=Vwoe...

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...

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.

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.
