If someone was applying for a job and they sent me a file like this, I'd hire them.

The south park satire of ICE is not satire.

"Jones, 27, is among the residents left at 7500 S. South Shore Drive who are trying to piece together what remains after an early morning, high-powered federal immigration raid led to the arrests of dozens of their neighbors at their South Shore apartment building."

Massive immigration raid on Chicago apartment building leaves residents reeling: 'I feel defeated'

The Department of Homeland Security said federal agents with Border Patrol, the FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives arrested 37 people in the raid.

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.

China’s EV supremacy raises national security concerns for the US

China is in the driver’s seat when it comes to EV technology—which poses huge defense implications for the U.S.

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 🤦‍♂️

Energy Dept. adds ‘climate change’ and ‘emissions’ to banned words list

It is the latest in a series of Trump administration efforts to dispute, silence or downplay climate change.

Doing harm to universities and science is the point

Science Magazine @science.org · 11d

NSF today released instructions for the next round of applicants to its Graduate Research Fellowship Program. A key group—second-year Ph.D. students—is no longer eligible, and students who are still able to apply will face an unusually narrow timeframe. https://scim.ag/3KlQkQk

‘Completely shattered.’ Changes to NSF’s graduate student fellowship spur outcry

The announcement comes months later than usual, leaving many would-be applicants stranded

Very cool experiment! Glad you were able to leverage surveydown for it :)

Btw, on performance we have found deploying on posit connect cloud to be much snappier

$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.

Robby DeGraff @robbydegraffap.bsky.social · 20d

Definitely bummed (albeit not super shocked) to see Nissan drop the Ariya for 2026 MY. Sales never took off, it trailed much of the competition, but there were a few good bits I liked, especially its interior design.
This is sadly what happens when an automaker executes an EV that is just "average".

Jonathan McPherson just mentioned datapasta at the opening keynote of #positconf, so I'm sharing this once again to share the magic, for all those discovering it for the very first time ❤️

🍝 A package I love, {datapasta}, came up at #CascadiaRconf this weekend, so I wanted to share a little example of it in action. It's an addin (but also a pkg w/ some funcs), so showing is better than sharing code. Thanks for the awesome pkg, @milesmcbain.bsky.social! #rstats #databs

duckdb is great for speed and doing analysis with large sizes. Data size is pretty small for surveys, and what we needed is something very mature and stable and easy to build on.

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

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.
