57 of my fellow students were arrested, academically disciplined, and barred from campus 2 weeks before finals.

And then the visas of some of those students were quietly revoked.

And then the DEI office was killed.

And then we watched our mentors’ grants evaporate over “woke”.

Every time I open a news app or site and this story isn’t being discussed or featured prominently I feel like I’m losing my mind. Do not look away.

With bookdown.org being decommissioned, I've been working on converting #rstats books from #bookdown to #quartopub. After spending a lot of time with Claude to get it right for my two books, here's a repo that might help you do the same (especially with Claude Code):

WATCH: Trump, EPA's Zeldin announce end of scientific basis for U.S. action on climate change The Trump administration on Thursday revoked a scientific finding that long has been the central basis for U.S. action to regulate greenhouse gas emissions and fight climate change, the most aggressiv...

Today, the Trump administration repealed the endangerment finding: the ruling that served as the basis for limits on tailpipe emissions and power plant rules. Without it, we’ll be less safe, less healthy and less able to fight climate change—all so the fossil fuel industry can make even more money.

Trump: ‘We should take over the voting’ Trump, as usual, offered no evidence for any of his claims.

President Donald Trump urged Republicans to seize control of elections and place voting under national authority Monday — one of his most explicit signals yet that he plans to interfere with the workings of democracy. www.democracydocket.com/news-alerts/...

Mapping Coastal Redwoods (Sequoia sempervirens) across their natural range: an updateable and field-validated distribution map using Sentinel satellite data and cloud computing Coast redwood (Sequoia sempervirens) is a uniquely-tall and long-lived tree species that occupies a narrow fog-belt along the Pacific coast of North America. Despite its ecological and conservation...

New paper led by Subham Banerjee, classifying coastal redwoods from Sentinel satellite data and mapping them across their entire natural range (true positive rate: 89%, false positive rate: 17%), all in GEE so that maps can be updated with new field training points and imagery over time!

Trump admin targets Boulder-based National Center for Atmospheric Research for dismantling The Trump administration is seeking to dismantle the Boulder-based National Center for Atmospheric Research (NCAR).

Gonna keep posting about this. Dismantling NCAR is stupid and dangerous; doing it as payback to the governor of Colorado is idiotic.

Map showing that most of SLCo only allows single-family

Map showing that most of SLCo only allows single-family

Why do we have a massive housing crisis in Salt Lake County? One of the key reasons is that most of the land zoned for residential uses only allows single-family homes. Also, SLC allows up to 4 units, but only if affordability requirements are met, so most of the city should be part of this map.
