Did you know it's possible for two lines to appear to diverge in a 2D perspective view, but actually converge in 3D? Kind of the opposite of parallel lines in 3D converging in 2D.
I discovered this while trying to implement a clipping algorithm. At first I didn't believe it was possible, it felt so foreign to everyday experience. It actually happens whenever two lines converge behind the center of projection, but we rarely see that IRL.

What appears to be a trapezoid, with the narrower base as a horizontal line near the center, getting wider towards the top, until it's cut off by the top edge of the image (forming the wider base).
3D orbit showing what's really going on: the 'narrower base' of the trapezoid was one side of a triangle, and the other two sides get closer together moving away from it, not farther apart.

This is the first time a book I've contributed to has gotten the subway platform publicity treatment.

I think I'm making progress on the bottom-of-column logic.
I've traced out a bunch, but I don't grok.
There's a bunch of control signals running the full height from bottom to top which makes tracing stuff out a bit painful.
The circuit that I thought was the column mux itself seems straightforward, just eight pass transistors that connect the drain-side bitlines to a common 8-bit bus on metal 2 running the full width of the array.
But then there's…

I was very excited (as folks could tell) and honored about having given the keynote at @… this year in Nara, Japan. Thanks everyone for their very kind reception of the talk! Thanks for inviting me!
I was talking about Wikipedia and the Semantic Web - 20 years of co-development and the future, sketching out how the two have and keep influencing each oth…

Relative to many, my life is very good,
-- in that I am alive and housed, fed, sometimes employed.
I am healthy and loved.
Still, I am about to lose my entire mind over the Free Application for Federal Student Aid (FAFSA) website,
and the fact that someone,
probably a bot farmer,
has already used my 16-year-old son’s identity to establish a fraudulent account.
This is a common scam,
one that was fortunately detected before any money changed …

FAFSA Is Breaking Me
I think I have been holding it together in the face of everything we can’t stop talking about—the killing and the dying, the explosions and the terror, the eggs and the bird flu and the shameless ghouls ruining the good parts of our country, the weapons and the

The frustrating thing is that none of this was an issue at the start of 2025. Microsoft appeared to be coalescing around a fairly standard user experience for the multitude of Copilot experiences available to customers. The foundation for the Windows app was a well-structured HTML experience with headings and more that made reading answers quite straight forward. Sometime after the start of the year, the Windows Copilot app appears to have changed some of the foundational technology used that …

Good ol' Roger Williams makes it into the London Review of Books! lrb.co.uk/the-paper/v46/n03/le

Democraticall Colin Kidd asks if any 17th-century philosopher can really be said to belong to the ‘liberal canon’ (LRB, 4 January). There is a case to be made, avant la lettre, for Roger Williams. Protégé of Edward Coke, and a Puritan émigré to New England, Williams outraged the Massachusetts theocracy by claiming that the state had no role in religion and that Native Americans had title to settler-occupied land. Expelled by the Boston authorities, he negotiated with the Narragansett for land f…

The propaganda is so wild. When I was younger, they'd lie about things 20-30 years prior, with the assumption that people will have forgotten. Now they are constantly attempting to rewrite history that happened a mere 5 years ago, thinking that they're slick.
To quote Orwell: "The Party told you to reject the evidence of your eyes and ears. It was their final, most essential command."

Renee DiResta noupside.bsky.social@bsky.brid.gy “Who was president in 2020?” is the question of our time [which quotes Senator Jim Banks saying, "The 2020 Census was a fraud. The Biden admin used a shady 'privacy' formula that scrambled the data and miscounted 14 states. It included illegal immigrants and handed Democrats extra seats. Americans deserve a fair count and I'm fighting to fix it."]

EEPROM update: Followed PROG_RD_EN to the output of a massive inverter north of the row decoders. Interestingly, it's got guard rings/tap terminals around it and has large (1.2um channel length) transistors, which suggests it's working with high voltage.
But one side of the inverter is driven by ground and the other by VCORE.
The input of the inverter comes from the block immediately to its left which I'm still tracing out and don't yet understand; the input of TH…
