[cx link] I was invited by the Future Observatory Journal of the Design Museum, London, to contribute to the ABUNDANCE issue. I wrote about energy and matter — about updating our understanding of which of these is abundant and which is scarce, and building our future.

Your great-great-grandparents commuted about an hour a day. So did Roman merchants. So do you. No matter how fast we make transportation, people just live farther from work regardless of income. It's called Marchetti's constant, basically Jevons paradox for your morning commute.

Unfortunately, the text that has been on my mind a lot the past year (and which is, even more unfortunately, very likely to be relevant in the *coming* year) is “How Complex Systems Fail”. how.complexsystems.fail

Will personally co-sign on this one — I bought a Beam Paints watercolour card (the Spectrum card) and they are just lovely paints.
A reminder to any canadian (or any) #watercolor artists. Beam Paints is an Indigenous owned company with beautiful plastic-free hues. Their sparkly metallics are to die for

I think this is why STS's focus on the non-teleological nature of technological change — and fields like media archaeology, which examine minor tools and history's losers — are so important in countering the "progress" and "inevitability" myths.
I find the idea that technology “evolves” via some sort of passive internal force of history extremely pernicious. The idea that things simply improve rather than very specific choices and efforts being made in targeted areas that then require new infrastructures to maintain is really dangerous.

Don't forget folks: allowing yourself a vision of the future you'd want for our country and planet - not the one you'd settle for, not the one you fear, but the future of your dreams - isn't naive, it's a vital cognitive skill. That's how we articulate what we most value. What's worth fighting for.
Instead of whatever this is, we should have a government getting lots of new homes and apartments built, lots of clean energy built, lots of high speed rail and transit and bike lanes built, human rights for everyone, economic & healthcare opportunities for all, & innovation that leads the world.

thinking about how, in the Russian history elective I took in HS, every time a tsar was facing domestic weakness the teacher would turn to the assembled students and ask "so what is it time for?" and we would chant "stunning territorial annexation!" and she would respond "well, DUH, girls"

A picture is worth 1000 words...

This appeared on the BBC News today, showing the increase in solar electric generation in the UK.

Not sure who produced it, but genuinely think this is a genius piece of scientific communication - the construct and choice of colour scale is near-perfect.

Chapeau!

In 2026 I want all of the decent people to remember one thing.

You aren’t meant to be this disciplined, this self-sacrificing to survive. The environment is supposed to support good living. We can have that. You are not a failure. That is politics.

That is all.

A useful clarification! Especially for people like me — I’ve had a Metrocard pretty much since they came out, despite never having lived in NYC, so I rarely know when I’ll use mine next. There’s no official ‘will not be accepted’ day announced yet.

Open up this picture fully.

Then look at the surface of Mars.

Then look up to the top right.

Spot Mars' moon Phobos high in the sky.

Then notice the bright spot beside Phobos.

That's Earth.

Just watched the new Knives Out and I think it’s really important you know that the scene in the Seminary’s Gym is filmed in the same place Rick Astley filmed the music video for Never Gonna Give You Up. I saw the window tracery and immediately made my friends pause the film so I could tell them.

And to be clear: the action one does if one is feeling guilty tonight or tomorrow is give cash to organizations feeding the hungry and sheltering the houseless. It is not to show up at a shelter and ask to serve food.

You gotta get vetted to volunteer, so you start with cash, put a reminder —
Pope Leo said in a Christmas Eve sermon that the story of Jesus being born in a stable because there was no room at an inn should remind Christians that refusing to help the poor and strangers today is tantamount to rejecting God himself. For @reuters.com
