This is interesting -- and has parallels in physics and climate science w.r.t. the balance between science for understanding and skillful prediction.

This is an interesting essay on methodological weaknesses in computer science and machine learning, exploring the limits of trying to accumulate knowledge mainly by building things.

So far, I have argued that there is a dissonance between, on the one hand, CS’s founding myths, curricula, and self-image, and, on the other hand, the modern production of knowledge in computer scienc...

You want to swish in the water until it is definitely done otherwise the white areas will go blue over time from the residual chemicals. I usually run it under a tap as a last step just to make sure I got it all.

Happy new year! My all sky camera imaged the sky every 15 seconds and this picture shows what happened in the sky in 2025. It shows the length of the night and day with the hourglass shape, the monthly lunar cycle with the diagonal bands, the elevation of the Sun at local noon, and lots of clouds.

The image shows the hourglass shape of the length of the day and night over the 365 days in 2025. Diagonal bands indicate when the Moon was up in the night sky.

In December 2025, Arctic sea-ice extent reached a record low - a substantial decline from the previous record low in 2024.

There's an interesting special section in the NYT today on the future of NYC, including the climate risks.

Notable is this graph of local changes in extreme rainfall:

A time series of the highest rainfall in an hour per year since 1948 in Central Park. There is some year to year variability, but the trend towards higher amounts is clear. The values first exceeded the city sewer capacity in 1995, then again in 2003, 2005, 2021, 2023, and 2025.

for anyone new to bluesky or just struggling to make their timeline better, here’s my tip:

follow a bunch of artists that you like and whenever they repost cool art, follow that artist too

soon your timeline will be a steady stream of wonderful art interspersed with news updates on the horrors

We used to do team code reviews and the author got chocolate for each critical thing they said about their own code. It can be an interesting perspective reviewing your own stuff.

Nice essay! I agree that GMST gets more attention than it perhaps merits and there's lots of loose talk around the concept.

For all that though, if we can't predict GMST a year a head, we might need to consider whether we can predict anything that far ahead.
