I made a Github repository a few days ago to automatically track changes to the GNIS database of place names in the US. Apparently it works. #Denali
A git diff showing Denali renamed to Mt. Mckinley by executive order

Am I too late for #30DayMapChallenge Day 14 - A World Map? I trained a model to predict MODIS RGB imagery from modern climate and applied it to modeled paleoclimate data to simulate a 22,000 year old satellite image of Earth
Title: MODIS RGB - Simulated at Last Glacial Maximum (~22k years ago). Subtitle: Basesd on WorldClim 1.4 downscaled CCSM (Hijmans et al, 2005). Earth from 3 different angles in natural color. It looks relatively similar to the modern world, but the northern hemisphere has much more ice and snow. Western Europe north of the Mediterranean, North America north of Kansas, and the Andes range in South America are white. Sea level was lower, so landforms are slightly larger than present day.

This was my tenth(!) year building 25 days of puzzles for #AdventOfCode. You can solve them all for free! Most people write code to solve them, but you can solve them however you like. I hope they help people become better programmers. 🌟 The first puzzle comes out in two hours: adventofcode.com

Foursquare just open sourced their 100 million place point of interest dataset! Some notes on poking around with it using DuckDB (it's Parquet files on S3) simonwillison.net/2024/Nov/20/...

Many fail to understand how the location of receiving stations impacted early data collection of polar orbiting satellites in the early days. That's the circular pattern in the early data. In former life I re-processed 1978-1991 vis/ir data back when Dinosaurs Walked (data on tape reels)

#30DayMapChallenge Day 11: Arctic One year of MODIS daily mosaic images Did you know optical satellites like MODIS usually don't capture images over the poles in winter due to lack of sunlight? The "no data" hole grows as we near the winter solstice - and starts closing once daylight returns

Visualizing how daylight hours change through the year depending on your latitude, for a blog post where I tried to figure out how far you'd need to travel to keep the same day length year-round (spoiler: not very far at first, then REALLY far at each equinox) www.aazuspan.dev/blog/chasing...
