On Markowitz's pseudodistance for conformal manifolds
In the 1980s, M. J. Markowitz introduced a conformally invariant pseudodistance on pseudo-Riemannian manifolds, inspired by the Kobayashi metric in projective geometry. This construction relies on a distinguished class of parametrized lightlike geodesics, called projectively parametrized. We begin by reviewing the fundamental properties of this pseudodistance and provide several families of examples where it is non-degenerate and, in some cases, complete. In particular, we investigate three cla…

Struggling Snap Considers Outside Funding for AR Glasses
For nearly as long as Evan Spiegel has run Snap Inc., his big bet has been on Spectacles, the company’s augmented reality glasses. All together, he has poured $3 billion into the effort—a fraction of what Mark Zuckerberg at Meta Platforms has invested in wearable technology, but a major expense ...

Haven't posted these in a while, but there's not much change:
Since @… has left #X/ #Twitter, we've seen a bit more

the "i am routinely looking at access logs of the static file server for purposes of development" version of "someone's talking about me, my ears are burning!":
someone (no idea who or where) posted a link to https://glasgow-embedded.org/latest/conduct.html

I don't think that "give beginners LLMs to get them started so they can actually learn to do it later" checks out.

But will they?
Armin Ronacher, who is quite a well-known open source developer (especially in the Python community) and who would probably consider himself a very rational, pragmatic person when it comes to “AI” usage posted an interesting post on Mastodon today: Post by @mitsuhiko View on Mastodon So his thought is that giving especially younger, less experienced […]

Trump started the verbal war with Canada shortly after the 2024 election.
He invited Prime Minister Trudeau to dine with him at Mar-a-Lago on November 29.
Trump said then that Canada should be the fifty-first state and that Trudeau should be its governor. (Later, Trump switched to Gretzky.)
“I look forward to seeing the governor again soon so that we may continue our in depth talks on tariffs and trade,” Trump posted on social media.
To this, Trudeau responded:

The New Detroit-Windsor Bridge Can’t Repair the Damage Trump Has Done
The opening of the Gordie Howe bridge has been delayed. It’s an apt metaphor for where U.S.-Canada relations have gone under Trump 2.0.

I am wondering if I am turning into a watch infuencer. 🤣 I was looking at a watch that has been out for a while but AFAIK nobody was discussing. It is a pocket watch and most of its dial is in Chinese, with unexpected markings as it is a 24 hour movement but 12 entries on the face.
While deciphering the dial I posted in a couple of different places. One related to translations and one for Chinese watch fans.
Looking now at the manufacturers site it states, "7 sold in last …
