There I fixed it

Incredible self own for the US. The damage being done to the US scientific enterprise is generational. We will look back on this as a tipping point where the US chose all on its own to stop leading the world in science. www.science.org/content/arti...

Now channel your inner Mitch McConnell and stick to it www.nytimes.com/2026/01/24/u...

Defund ICE or shut the government down. This is the moderate position.

People are holding on to hope with "but the Generals wouldn't obey that order right?" and 1) that says a LOT about where we are right now and 2) you better believe they 100% would follow that order, and if not there are hundreds in line who would I mean look at who they put in charge of DoD ffs

For the record, as an American, I think threatening tariffs on our closest European allies and fellow NATO members because they are standing up to US threats to forcibly annex Greenland is bad.

Most Americans have no idea how immensely pissed Canadians are at the US. I'm not Canadian, but have family there, and the damage from the US's betrayal will last a generation or more. There's no returning to the prior relationship regardless who takes power in the US.

It begins. Canadians will soon experience the vast superiority of Chinese EVs, and the US will lose its largest vehicle export market. The transition will happen much faster than people think.

Updated my LLM / AI policy for my intro to #Rstats programming course this semester: p4a.seas.gwu.edu/2026-Spring/... Largely inspired by @andrew.heiss.phd post: lnkd.in/e_Sr2D-5

It's a DS workshop by @andrew.heiss.phd, what more do you need to know? You should check it out #rstats #positron

🤌

It's all too obvious why any regime as unpopular as the current one would work so hard to silence public data infrastructure www.bloomberg.com/news/article...

Two more shot. Shut it down until the lawlessness ends. www.nytimes.com/2026/01/08/u...

I swear to God if the shoe were in the other foot there is NO WAY the Rs would have let this obscene level of lawlessness go on. The Ds need to grow a pair and start pulling from the old Mitch McConnell playbook.

If they're murdering people in broad daylight with cameras rolling, imagine what they're doing to the thousands being held in the camps.

They're literally murdering us

For those too young to remember the lead up to the invasion of Iraq, this is actually nothing like that. The Iraq invasion (though built on lies) was approved by Congress. This is much more like Putin's illegal invasion of Ukraine, or Germany into Poland, etc.

Please please please EV designers, bring back buttons and just make normal cars that are electric nobody wants to turn on their wipers with a touch screen! 🙏

Every person who voted for this criminal because they wanted to get the US out of foreign wars will now cheer and justify this with all kinds of BS. Call them out every time.

And people weren't taking his threats about annexing Canada or Greenland seriously

Polestar EVs are wonderful. They're the closest thing you can get to a proper Chinese EV in the US...if only people knew how much better EVs can really get

TidyTuesday and the DSLC have both been amazing resources for years. This is a great cause to support to keep it alive and sustainable for years to come!

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/

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-...
