West Texas energy infrastructure identified from satellite imagery using zero-shot image segmentation.
Shown:
Well pads from simple text prompts;
Draw a box around a wind turbine, find the others in the view;
Click a solar farm, segment the area.

Showed my Advanced GIS students Claude Code this week.
We built this map of code compliance violations in Fort Worth; heatmap giving way to points on zoom.
Used the ArcGIS SDK for JavaScript.
Took 10 minutes.
I believe in Jevons Paradox.
But we need to be teaching skills for 2026, not for 2016.

alright, for the "negative filtering of df in #rstats" illustration @sobchuk.bsky.social asked for subset() - so here it is! That should be all the basic bases covered, fingers crossed.
Note that it might look like dplyr::filter & subset are doing the same thing, but look at the rownumbers..
