This morning you missed migas. I did not but only because I rushed to eat them and then go testify to maybe save our transit system. Tea and coffee, sausage. Bad day here: still no money for buses. #TogetherBreakfast https://photos.app.goo.gl/g3k9gWquiJL6gEow8

“​​Rubber burns, the map fades away / Chasing the ghosts of yesterday.” Sure, fine.

Holographic symmetry algebra for the MHV sector revisited
We revisit the holographic symmetry algebra in the MHV sector. We find an infinite dimensional Abelian symmetry algebra whose generators are the conformally soft negative helicity gravitons and gluons. So the complete symmetry algebra in the MHV graviton sector is a semideirect product of the $w_{1+\infty}$ algebra and the infinite dimensional Abelian algebra. Similarly in the MHV gluon sector the symmetry algebra is a semidirect product of the $S$ algebra and the infinite dimensional Abelian a…

This afternoon I will start a project that I postponed all summer: Figuring out how to move my club collective's web stuff to a new provider. (*shakes fist at Hosteurope which should burn in hell for switching their mail service to bloody Microsoft 365 model with a monthly fee per every single email adress*) Last time I did this was 15 years ago and I can't wait to relearn / see what has changed and is more complicated today! 😅

Oof. #OpenStreetMap minutely replication is currently broken: https://community.openstreetmap.org/t/131884
For me this means that recent edits I made are not queryable via O…

Is OSM partially down? New data isn't able to be queried on the map, and new data isn't being rendered
I’m finding that I can pull data into JOSM and iD that I know exists (due to recently pushed edits), but a query on the map doesn’t list them (not to mention that they also aren’t being rendered; however, when something’s awaiting rendering, I always, at least by my experience, can still query it). For example, this query should list building=toilets, but it doesn’t. If I edit that location in iD I can see the aforementioned feature, and I can also pull it into JOSM, but it isn’t b…

The homological spectrum for monoidal triangulated categories

The homological spectrum for monoidal triangulated categories
The authors develop a notion of homological prime spectrum for an arbitrary monoidal triangulated category, ${\mathbf C}$. Unlike the symmetric case due to Balmer, the homological primes of ${\mathbf C}$ are not defined as the maximal Serre ideals of the small module category ${\sf mod}\text{-}{\mathbf C}$, or via a noncommutative ring theory inspired version of this construction. Instead, the authors work with an extended comparison map from the Serre prime spectrum $\operatorname{Spc} ({\sf m…

SmartFlow: A CFD-solver-agnostic deep reinforcement learning framework for computational fluid dynamics on HPC platforms
Deep reinforcement learning (DRL) is emerging as a powerful tool for fluid-dynamics research, encompassing active flow control, autonomous navigation, turbulence modeling and discovery of novel numerical schemes. We introduce SmartFlow, a CFD-solver-agnostic framework for both single- and multi-agent DRL algorithms that can easily integrate with MPI-parallel CPU and GPU-accelerated solvers. Built on Relexi and SmartSOD2D, SmartFlow uses the SmartSim infrastructure library and our newly develope…

Just finished "Concrete Rose" by Angie Thomas (I haven't yet read "The Hate U Give" but that's now high on my list of things to find). It's excellent, and in particular, an excellent treatise on positive masculinity in fiction form. It's not a super easy book to read emotionally, but is excellently written and deeply immersive. I don't have the perspective to know how it might land among teens like those it portrays, but I have a feeling it's true enough to life, and it held a lot of great wisdom for me.
CW for the book include murder, hard drugs, and parental abandonment.
I caught myself in a racist/classist habit of thought while reading that others night appreciate hearing about: early on I was mentally comparing it to "All my Rage" by Sabaa Tahir and wondering if/when we'd see the human cost of the drug dealing to the junkies, thinking that it would weaken the book not to include that angle. Why is that racist/classist? Because I'm always expecting books with hard drug dealers in them to show the ugly side of their business since it's been drilled into me that they're evil for the harm they cause, yet I never expect the same of characters who are bankers, financial analysts, health insurance claims adjudicators, police officers, etc. (Okay, maybe I do now look for that in police narratives). The point is, our society includes many people who as part of their jobs directly immiserate others, so why and I only concerned about that misery being brought up when it's drug dealers?
