I can’t get enough of #rutgerbregman ‘s first #reithlecture . His analysis of the decay of the West seems accurate to me, but what I really love is his optimism for a future built on a moral revolution. His proposition: just imagine what we could achieve if we self organise and work together…

The Reith Lectures - Rutger Bregman - Moral Revolution - 1. A Time of Monsters - BBC Sounds
Dutch historian Rutger Bregman delivers his first BBC Reith Lecture: Moral Revolution.

I'm thinking of (1) recording my #PIM lecture as a larger set of 5-30min video snippets (1 for each sub-topic) and/or
(2) writing a book with even more background information on the same subject including further links.
What would you consider more important to you personally?
Please do limit yourself to not more than 2 choices even if they are hard to do.

Wow, what a wonderful day at @… ! They put on a great conference and I was honored to have been part of it. I held a privacy workshop and gave a #fedvierse talk. I just posted the worksheets from the workshop and the presentation from the talk over on the …

No, I do not know whether I am using Willo 1.3 LTI with my large lecture course LMS (troubleshooting course management issues with a third party #EdTech platform).

I just wanted to quickly typst an example for the lecture tomorrow and suddenly I'm on #oeis again: https://oeis.org/A088138
I think this sequence is the result of the tri-diagonal determinant of twos, but it does not appear in the OEIS comments at all!
In fact, most comments are about a sequence with different signs, for example the first comment gives the generating function for that other sequence. Why?
The recursion is a_n = 2 a_(n-1) - 4 a_(n-2) and the formula is in the 2. pic, I hope.

Lecture notes on the symplectic geometry of graded manifolds and higher Lie groupoids
In this work, we study symplectic structures on graded manifolds and their global counterparts, higher Lie groupoids. We begin by introducing the concept of graded manifold, starting with the degree 1 case, and translating key geometric structures into classical differential geometry terms. We then extend our discussion to the degree 2 case, presenting several illustrative examples with a particular emphasis on equivariant cohomology and Lie bialgebroids. Next, we define symplectic Q-manifolds …

Well, curves defined by THAT equation…
Just come to my linear algebra lecture starting next week. 😬
