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.

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…
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?
The Greenland sea cables are probably being closely monitored, but redundancy seems minimal likely limited to OneWeb satellite connectivity and some VSAT links.
Looking at the routing side, AS8818 announces just two /19s and one /22 (and two /32s in IPv6) with a single upstream provider, Level 3 Inc. This suggests that Layer 3 redundancy is even more constrained.
I would have expected at least one EU-based provider as an additional upstream...

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 …

"So imagine the Brownstone startup puts 50 pods in one big room. Once they rent pod #1, that person appears to have the right to the entire room. Renting pods #2 through #50 could violate Section 1950. If they do, they are double letting, and 'every tenant in the building, under the same landlord' could withhold rent for as long as the 'double letting' continues." 👀
