We need something like iWeb for many things… Bento was another nice piece of software of the same vein… And of course HyperCard. That’s the Apple I miss the most.

Florida’s Everglades National Park is often referred to as the most endangered national park in the United States.
In 1968, developers tried to construct the largest airport in the world in the middle of the park,
which was already suffering from a multitude of environmental crises:
disrupted water flow, a drastic decline in the bird population, human development, invasion of exotic species, and the endangerment of the Florida panther.
After an upswell of public outcry…

DeSantis Races to Open Immigrant Detention Camp in Swamp Amid Hurricane Season
Even before “Alligator Alcatraz,” Ron DeSantis had defined his political legacy by gleeful cruelty against immigrants.

Mirror descent for constrained stochastic control problems
Mirror descent is a well established tool for solving convex optimization problems with convex constraints. This article introduces continuous-time mirror descent dynamics for approximating optimal Markov controls for stochastic control problems with the action space being bounded and convex. We show that if the Hamiltonian is uniformly convex in its action variable then mirror descent converges linearly while if it is uniformly strongly convex relative to an appropriate Bregman divergence, the…

Poster: FedBlockParadox -- A Framework for Simulating and Securing Decentralized Federated Learning
A significant body of research in decentralized federated learning focuses on combining the privacy-preserving properties of federated learning with the resilience and transparency offered by blockchain-based systems. While these approaches are promising, they often lack flexible tools to evaluate system robustness under adversarial conditions. To fill this gap, we present FedBlockParadox, a modular framework for modeling and evaluating decentralized federated learning systems built on blockcha…

Disintegration theorem for multifunctions, with applications to empirical Wasserstein distances and average-case statistical bounds
We prove a generalisation of the disintegration theorem to the setting of multifunctions between Polish probability spaces. Whereas the classical disintegration theorem guarantees the disintegration of a probability measure along the partition of the underlying space by the fibres of a measurable function, our theorem gives necessary and sufficient conditions for the measure to disintegrate along a cover of the underlying space defined by the fibres of a measurable multifunction. Building on th…

Are Crypto Ecosystems (De)centralizing? A Framework for Longitudinal Analysis
Blockchain technology relies on decentralization to resist faults and attacks while operating without trusted intermediaries. Although industry experts have touted decentralization as central to their promise and disruptive potential, it is still unclear whether the crypto ecosystems built around blockchains are becoming more or less decentralized over time. As crypto plays an increasing role in facilitating economic transactions and peer-to-peer interactions, measuring their decentralization b…

The first group of immigrants has arrived at a new concentration camp deep in the Florida Everglades that officials have cynically dubbed “Alligator Alcatraz”
The facility, at an abandoned airport, will have an initial capacity of about 3,000 detainees, DeSantis said.
The center was built in eight days and features more than 200 security cameras,
28,000-plus feet of barbed wire and 400 security personnel

First immigration detainees arrive at Florida center in the Everglades
The first group of immigrants has arrived at a new detention center deep in the Florida Everglades that officials have dubbed “Alligator Alcatraz.” Florida Republican Attorney General James Uthmeier said on social media Wednesday that “hundreds” of immigration detainees were to arrive at the center. Republican Gov. Ron DeSantis says the facility will have a capacity of about 3,000 detainees when fully operational. The center was built in eight days and features more than 200 security ca…
