Algebraic Limits of Sandpiles
The paper contributes to building algebraic foundations of self-organized criticality answering a previously unsolved question about the limiting structure of the extended sandpile group as well as relating it to another limit at the level of classical sandpile groups with respect to certain monomorphisms, and puts forward a concept of canonical sandpile epimorphisms, drawing an unexpected consequence about the divisibility properties of the numbers of spanning trees on rectangles.

On commensurators of free groups and free pro-p groups
We study the commensurators of free groups and free pro-$p$ groups, as well as certain subgroups of these. We prove that the commensurator $Comm(F)$ of a non-abelian free group of finite rank $F$ is not virtually simple, answering a question of Lubotzky. On the other hand, we exhibit a family of easy-to-define finitely generated subgroups of $Comm(F)$ and show that some groups in this family are simple. For a prime $p$, we also consider the p-commensurator $Comm_p(F)$, which is the commensura…

News from WWDC25: WebKit in Safari 26 beta
Welcome to WWDC25!

My least favorite work interactions are with customers’ 3rd party “rockstar” consultants. I never know how to respond to certain sorts of queries. Ones where I could answer the question as asked but it really implies a deeper misunderstanding. I feel like I want to write him a treatise on VPNs: what they are and how they work. And Cc his boss (who shares his surname…) to communicate the depth of the problem.
I’m letting my boss handle it. He’s the networking guy anyway…

AnnoGram: An Annotative Grammar of Graphics Extension
Annotations are central to effective data communication, yet most visualization tools treat them as secondary constructs -- manually defined, difficult to reuse, and loosely coupled to the underlying visualization grammar. We propose a declarative extension to Wilkinson's Grammar of Graphics that reifies annotations as first-class design elements, enabling structured specification of annotation targets, types, and positioning strategies. To demonstrate the utility of our approach, we develop a …

Organic Crystal Active Waveguide as an All-Angle Signal Receiver and Transmission Platform for Visible Light Communication
Organic crystal waveguides, known for excellent light-guiding and photonic versatility, present a promising alternative to conventional optical media in visible light communication (VLC) systems. In a novel approach, the high photoluminescence quantum yield organic crystal 2,2dash-((1E,1Edash)-hydrazine-1,2-diylidenebis(methaneylylidene))diphenol (SAA) is used as an optical waveguide medium for real-time data communication in the visible range, employing a microcontroller unit with on off keyin…

Agentic Distributed Computing
The most celebrated and extensively studied model of distributed computing is the {\em message-passing model,} in which each vertex/node of the (distributed network) graph corresponds to a static computational device that communicates with other devices through passing messages. In this paper, we consider the {\em agentic model} of distributed computing which extends the message-passing model in a new direction. In the agentic model, computational devices are modeled as relocatable or mobile co…

A Hollywood producer calls a friend, another producer on the phone.
"Hello?" his friend answers.
"Hi!" says the man. "This is Bob, how are you doing?"
"Oh," says the friend, "I'm doing great! I just sold a screenplay
for two hundred thousand dollars. I've started a novel adaptation and the
studio advanced me fifty thousand dollars on it. I also have a television
series coming on next week, and everyone …
