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.

Jason Proctor is contributing to the CBC's live blog scroll from a legal perspective and as always, his stuff is illumniating. I'll paste his report in because it can get lost in the scroll easily.
"Creditors circle as cull looms
Jason Proctor
I'm Jason Proctor, a reporter with CBC Vancouver who looked into a series of lawsuits facing the owners of Universal Ostrich Farms Inc.
Last month, I spoke with three creditors who are watching today's ruling with great interest — and some skin in the game.
B.C. Supreme Court judges have ordered the farm's owners to repay debts worth more than $250,000 but, up until now, the creditors have been unable to collect. Normally in this kind of situation, a creditor would move to seize the business assets — but because in this case those assets are ostriches caught up in a legal battle, that's been challenging, to say the least.
All three creditors have tried to garnish the CFIA to intercept any money the agency might pay out as compensation for killing the birds (potentially up to $3,000 a bird, the CFIA says) but it remains to be seen how that will work. The creditors, however, told me they are anxious to recoup their losses.”

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 packed for #POTA before heading out to do the weekly grocery shopping, even though it was only 40°F / 4.5°C with low clouds. I decided it was too cold to sit in the helinox chair without insulation, so I drove past US-3867 and went to US-2755 Umstead State Park instead, where I could sit at a picnic table. I took a floor mat out of my car to sit on. As it was, it was cold enough that I co…

Two screenshots of the lock screen on my iPhone 17 Pro whose difference confounds me. In one the contrast is good and I can read the numbers on the pad, but the time and battery status are hidden. In the other, the key pad is pretty much invisible but I can see the time and battery. I have no idea how to trigger the contrastier one; it just sometimes does this.
Is this phenomenon known? Explicable? It's as if the new UI is sometimes ashamed to show how unreadable it is and compensates before hiding again.
Somebody made this happen. Any idea why?

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 …

“Windows Copilot Serves At Best Half an Answer to Screen Reading Users”

Kelly Ford is unintentionally describing when a pattern in a…

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 …
