chipfiring: A Python Package for Efficient Mathematical Analysis of Chip-Firing Games on Multigraphs
This paper presents `chipfiring`, a comprehensive Python package for the mathematical analysis of chip-firing games on finite graphs. The package provides a robust toolkit for defining graphs and chip configurations (divisors), performing chip-firing operations, and analyzing fundamental properties such as winnability, linear equivalence, and divisor rank. We detail the core components of the library, including its object-oriented graph and divisor implementations, integrated Laplacian matrix c…

The DOGE team at SSA might have violated FISMA and other laws by not following security protocols as spelled out in NIST's SP 800-53, which are mandatory for all government agencies.
It's no surprise then that a whistleblower is warning that we have lost the ability to see who is accessing 300 million Americans' most sensitive information after DOGE moved SSA data to their own Amazon cloud instance.
Thanks to John Skinner, former project lead for 18F, for his expert i…

Whistleblower: DOGE put Social Security database covering 300 million Americans on insecure cloud
The complaint accuses DOGE of bypassing security protocols to move Americans’ sensitive personal data outside federal oversight and onto an insecure AWS cloud instance, potentially violating established security practices and several laws.

Public Acceptance of Cybernetic Avatars in the service sector: Evidence from a Large-Scale Survey in Dubai
Cybernetic avatars are hybrid interaction robots or digital representations that combine autonomous capabilities with teleoperated control. This study investigates the acceptance of cybernetic avatars in the highly multicultural society of Dubai, with particular emphasis on robotic avatars for customer service. Specifically, we explore how acceptance varies as a function of robot appearance (e.g., android, robotic-looking, cartoonish), deployment settings (e.g., shopping malls, hotels, hospital…

Les États-Unis prévoient de déplacer toute la population du Territoire palestinien du Gaza. Ceux qui accepteraient de partir recevraient 5000 USD ainsi qu'une aide couvrant quatre ans de loyer et un an de nourriture. Les propriétaires terriens se verraient quant Š eux offrir des "jetons numériques", Š utiliser pour financer une nouvelle vie ailleurs ou Š échanger contre un appartement dans l'une des six Š huit nouvelles "villes intelligentes et alimentées par l'IA".

I tried hunting POTA with five different #HamRadio antenna arrangements while taking a short holiday at the beach over the past few days. I tried the built-in antenna on my KX3, a 20m vertical with radials on a deck, the same vertical with radials stuck with a stake into the top of a sand dune, and two inverted-V 40m end-fed half wave arrangements on a spiderbeam, a north/south and an e…
