And that's a wrap - the newly refreshed laptop has been handed over to teen with most of the packages functional. Thanks for following along on this @… installation journey with me and thanks to all #linux maintainers, forum contributors and FOSS advocates around keeping the system running.
👏 WE REALLY APPRECIATE YOU!👏
The final judgement won't be clear until Monday when the first log in at school happens but hopefully it will be successful, or the IT support is going to have to deal with some very salty comments (from me).

Picture the human body. Zoom in on a single cell. It lives for a while, then splits or dies, as part of a community of cells that make up a particular tissue. This community lives together for many many cell-lifetimes, each performing their own favorite function and reproducing as much as necessary to maintain their community, consuming the essential resources they need and contributing back what they can so that the whole body can live for decades. Each community of cells is interdependent on the whole body, but also stable and sustainable over long periods of time.
Now imagine a cancer cell. It has lost its ability to harmonize with the whole and prioritize balance, instead consuming and reproducing as quickly as it can. As neighboring tissues start to die from its excess, it metastasizes, always spreading to new territory to fuel its unbalanced appetite. The inevitable result is death of the whole body, although through birth, that body can create a new fresh branch of tissues that may continue their stable existence free of cancer. Alternatively, radiation or chemotherapy might be able to kill off the cancer, at great cost to the other tissues, but permitting long-term survival.
To the cancer cell, the idea of decades-long survival of a tissue community is unbelievable. When your natural state is unbounded consumption, growth, and competition, the idea of interdependent cooperation (with tissues all around the body you're not even touching, no less) seems impossible, and the idea that a tissue might survive in a stable form for decades is ludicrous.
"Perhaps if conditions were bleak enough to perfectly balance incessant unrestrained growth against the depredations of a hostile environment it might be possible? I guess the past must have been horribly brutal, so that despite each tissue trying to grow as much as possible they each barely survived? Yes, a stable and sustainable population is probably only possible under conditions of perfectly extreme hardship, and in our current era of unfettered growth, we should rejoice that we live in much easier times!"
You can probably already see where I'm going with this metaphor, but did you know that there are human communities, alive today, that have been living sustainably for *tens, if not hundreds of thousands of years*?

P.S. if you're someone who likes to think about past populations and historical population growth, I cannot recommend the (short, free) game Opera Omnia by Stephen Lavelle enough: https://www.increpare.com/2009/02/opera-omnia/

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.

An algebra modality admitting countably many deriving transformations
A differential category is an additive symmetric monoidal category, that is, a symmetric monoidal category enriched over commutative monoids, with an algebra modality, axiomatizing smooth functions, and a deriving transformation on this algebra modality, axiomatizing differentiation. Lemay proved that a comonoidal algebra modality has at most one deriving transformation, thus differentiation is unique in models of differential linear logic. It was then an open problem whether this result extend…

The lattices $\textbf m\times\textbf 2$ and $\textbf m\times\textbf 3$ are not Schur positive
We prove that the lattices $\textbf m\times\textbf 2$ and $\textbf m\times\textbf 3$ are not Schur positive for $m\ge 8$. This confirms a conjecture of Li, Qiu, Yang, and Zhang, as an extension of counterexamples to a comment of Stanley on the universal Schur positivity of distributive lattices. Our main tools include Pieri's rules, and Wang and Wang's combinatorial formula for computing any Schur coefficient of the chromatic symmetric function of a graph in terms of special ribbon tabloids. We…

Scalar-tensor theories in the Lyra geometry: Invariance under local transformations of length units and the Jordan-Einstein frame conundrum

Scalar-tensor theories in the Lyra geometry: Invariance under local transformations of length units and the Jordan-Einstein frame conundrum
The Lyra geometry provides an interesting approach to develop purely geometrical scalar-tensor theories due to the natural presence of the Lyra scale function. This paper explores further the scale function source term to construct a theory on Lyra manifolds which contains proper generalizations of both Brans-Dicke gravity and the Einstein-Gauss-Bonnet scalar-tensor theory. It is shown that the symmetry group of gravitational theories on the Lyra geometry comprises not only coordinate transform…
