Let's do a proper #Caturday song for today's #MusicRecommendation:

Even though my house was destroyed
Even though if I go bankrupt
Everything is fine if cats are feeling good
The shape of love in my sacrifice

Former GM Confident Steelers Are Better Fit For Russell Wilson Over Las Vegas Raiders
The Pittsburgh Steelers' fan base has been on an emotional rollercoaster since the 2023 season officially ended following a Wild Card loss to the Buffalo Bills. The team has plenty of holes on the roster and if you asked the front office two years ago if quarterback would be one of the talking points in the 2024 offseason, they would have vehemently shot down the idea. Kenny Pickett has been underwhelming during his two NFL seasons and talk has shifted from Justin Fields being acquired via t…

On Matrices over a Polynomial Ring with Restricted Subdeterminants
This paper introduces a framework to study discrete optimization problems which are parametric in the following sense: their constraint matrices correspond to matrices over the ring $\mathbb{Z}[x]$ of polynomials in one variable. We investigate in particular matrices whose subdeterminants all lie in a fixed set $S\subseteq\mathbb{Z}[x]$. Such matrices, which we call totally $S$-modular matrices, are closed with respect to taking submatrices, so it is natural to look at minimally non-totally $S$…

The swifts (Mauersegler) are back. We’ve been waiting for them for some days now. Today my wife and I were talking about it and then spotted the first scouts. We love their joy, play and acrobatics in the sky. Soon there will be hundreds around. But hard to photograph because they are so fast.

Moduli of sheaves on fourfolds as derived Lagrangian intersections
We show that any $(-2)$-shifted symplectic derived scheme $\textbf{X}$ (of finite type over an algebraically closed field of characteristic zero) is locally equivalent to the derived intersection of two Lagrangian morphisms to a $(-1)$-shifted symplectic derived scheme which is the $(-1)$-shifted cotangent stack of a smooth classical scheme. This leads to the possibility of the following viewpoint that is, at least to us, new: any $n$-shifted symplectic derived scheme can be obtained, locally, …

"The Marvels" is a terrible film but it's a terrible film because Marvel make terrible films, not because it's female-led or "woke" or any of the other nonsense reasons the right-wing loons spouted. It's no worse than any of The Avengers or Fast and Furious or Mission Impossible etc.

Spotted a yellow-crowned night heron and a black rat snake on yesterday's neighborhood walk. (I think that's what they are, but open to being corrected.)
Saw them both within 100-150 ft of each other, on the 6th km of an otherwise uneventful 7.5km walk. 😀
Snake video 👇🏽 (none of my clients were able to attach both videos to this post).
