So we just got through the bitcoin/crypto fad (I mean it's still there but not as hype as LLM AI hype) and now we're still swimming in โ€œAI" nonsense and next it's going to be "quantum computing" and honestly I can't wait for climate collapse to destroy all technology. I don't want to contemplate what the post-quantum grift is going to be.

Screenshot of a Forbes headline that reads: โ€œWhatโ€™s Next After AI: The Future of Quantumโ€ by the very smart dude Guy Diedrich, Forbes Councils Member.

This could be a game changer for anyone using model custom QuerySets and Managers ๐ŸŽ‰ I've just implemented an 11 years old ticket ๐Ÿง“ for initial filters on model QuerySets handled in such an elegant way ๐Ÿ’Ž

objects = QuerySet.filter(active=True).as_manager()

You *can* build a decentralized technical / internet system which is actually decentralized, of course. There are lots of examples of that too. But since that isn't the kind of system capitalism naturally builds, what you probably won't do is get *funding* to create that system. And that means *completing* your decentralized system is hard and gets harder the further past 1990 we get and the more you expect your decentralized system to do.

@mcc I thought this before, the internet's key resilient design principle is diametrically opposed to capitalism's requirement for control of resource(s) and cultivation of dependency - eg in capitalism you want to own the only bridge over the river.

Atmospheric refraction, due to the different temperature/altitude profile in the atmosphere at different times of day...makes distant mountains appear taller or shorter.

The attached photo is a comparison of what I shot yesterday afternoon and this morning. The camera was set up within inches of the same location for both shots, and those mountains are between 50 and 120 miles away...so I'm saying that any parallax effect from camera location is essentially zero.

I have annotated with arrows where it's easy to make a comparison of how the near and far ridge lines overlap differently in the two photos.

This is a follow up to:

Imagine the care that was needed to conduct surveys before the GPS/GNSS era:
explorersweb.com/the-five-men-

"The Great Theodolite built by Troughton & Simms in London stood nearly 1.5m high, had a horizontal circle one meter in diameter, and could read angles to a single second of arc. Moving it required 30 porters and sometimes elephants."

"The reduction of Nicolsonโ€™s observations was a colossal task. Each ray from each station had to be corrected for instrumental error, for temperature and pressure, and for the curvature of the Earth. Above all, they needed to correct for atmospheric refraction, which at those distances could amount to six or seven minutes of arc and change from hour to hour."

A comparison of two photos of the same distant mountain ridges. Arrows show places where the ridgelines overlap in different ways in the two photos. The top photo is grayscale, the bottom one is color.The great theodolite. Photo: Survey of India Archives

Capitalism is *all about*, at its core, building decentralized systems which on inspection turn out to be centrally controlled, or controlled via a "one dollar one vote" democracy of the five or six richest people in the system (in other words informal centralization, without the committee that makes the decisions having a name).

The decentralized internet systems that capitalism builds reflect this. There's lots of examples of it. Bitcoin, Ethereum, Bluesky.
