This post by Cory Doctorow is so, so good - and this puts into words what I’ve been so frustrated about. This is not how you teach kids to write.

Nature Report, Killed by Trump, Is Released Independently

The "national nature assessment" that Trump didn't want you to read has now been independently published. Big shocker: The natural world is in bad shape! www.nytimes.com/2026/03/05/c... via @catrineinhorn.bsky.social

540NR? It's six pages.

How did they pay you? One dollar to trigger every schedule that exists?

I've experienced and paid a lot of scenarios, nothing more than a dozen or so pages.

In 2023, there was not a single day until spring where WindWaterSolar met >100% of demand for part of the day.

During winter 2026, so far there are already 45 of 68 such days (66%), and 18 straight.

And gas use is now down 60% vs '23
Solar up 61%, batteries up 322% vs '23

Imagine a world where Americans were smarter and didn’t applaud when reactionary idiot Ronald Reagan made a show out of removing the solar panels Jimmy Carter had installed on the White House. We wouldn’t now have to worry about affording to fill gas tanks next month.

My entire journalistic career, editors & owners & bosses told me again & again that my stuff was too long, too in-depth, too wonky, no one would read it.

Again & again, readers flocked to the longer, wonkier pieces, passed them around, wrote me to thank me for them, cited them years later.

Under Secretary ...

This is a great complement to @X's community notes system, which results in less
"reach" (thus monetization) for content annotated as inaccurate.

Happy to see Sarah Rogers, who was lying in a hearing yesterday ab Stanford Internet Observatory being part of a cabal of Stasi NGOS (what?), come out in support of my past argument ab β€œfreedom of speech not freedom of reach” & the importance of supplementing CN w/ incentives. Glad we agree, Sarah!

I was reading this report and got to "as of 9:30 PM Monday" & tripped mentally, looked at the time and it was 9:42.

Hot off the press!

Northern California’s first condor egg in 100 years reported in redwood tree

Northern California’s first condor egg in 100 years reported in redwood tree

Who COULDN’T use some good news? β€˜ Scientists with the Yurok Tribe say that two of dozens of condors released to the wild in Humboldt County since 2022, to reestablish the endangered birds, have paired up, built a nest in a redwood tree and appear to be tending to an egg.”

Excellent article by @bobkopp.net describing the attacks on climate science by the Trump administration and calling for the research community to find a better strategy to respond. Articles like this are a critical to letting people know the full scope of what's being done to science.

The more significant war on national parks is the removal of reservations for the most popular parks.

With the overcrowding, this was a simple improvement that effectively managed the crowds and delivered a positive experience for everyone.

Without, the experience will be worse for everyone.

@aarnegranlund.bsky.social You live in an beautiful area with specific energy needs.

In Southern California, home to a significant percentage of the global GDP, net-zero with solar alone is trivial.

The mistake is to generalize.

Do you think the methodology of this paper makes sense?

"Heterogeneity analysis indicates that urban counties, counties with interconnected grids, and states with high solar generation exhibit significantly higher vulnerability."

Do you think interconnected grids increase vulnerability? Solar?

A standing reminder: a small handful of Republicans in Congress could stop this chaos tomorrow. They simply choose not to.

This process is essential to learning about a dataset and understanding it. Skipping it results in output that cannot be trusted. "cleaning" is the least of it.

Using Bullshit Bots for analysis and coding simply postpones the process of understanding and validation. And encourages skipping it.

It's of course OK to argue that the reasons given by the Trump regime for the tariffs are nonsense, but it's deeply stupid to still pretend that his tariffs are some kind of reasoned economic policy in the interest of the US.

The ICE surge in Minnesota cost $280M, to detain 4k people of whom only 30 were accused of violent crimes.

$9 million per capture of the "worst of the worst". Plus two citizens murdered.

The funny part is that Ms. Stodden would be shocked to learn that if she rejected the use of all the "communist code", her life, as she knows it, would end.

GPL code is everywhere, making everyone's life better.

The stupidest part of her thinking is describing "share-alike" as "counter to scientific norms" and describing it as somehow opposed to the "public good". Moglen is a staunch supporter of GPL. GPL is communist, in a positive sense. It's widely used because it PROMOTES THE PUBLIC GOOD!
