Sourced Carrollian Fluids Dual to Black Hole Horizons
The (degenerate) geometry of event horizons is linked to Carrollian fluids. We investigate the behavior of event horizons via a perturbative coupling to a massless scalar field, making connections to Carrollian hydrodynamics with a driving source, and discuss the fluid equilibration in tandem with the horizon's relaxation to equilibrium. We observe that after the perturbation dies off, the Carrollian fluid energy and momentum densities approach equilibrium as the horizon asymptotically becomes …

The Social Context of Human-Robot Interactions
The Human-Robot Interaction (HRI) community often highlights the social context of an interaction as a key consideration when designing, implementing, and evaluating robot behavior. Unfortunately, researchers use the term "social context" in varied ways. This can lead to miscommunication, making it challenging to draw connections between related work on understanding and modeling the social contexts of human-robot interactions. To address this gap, we survey the HRI literature for existing defi…

OrbitChain: Orchestrating In-orbit Real-time Analytics of Earth Observation Data
Earth observation analytics have the potential to serve many time-sensitive applications. However, due to limited bandwidth and duration of ground-satellite connections, it takes hours or even days to download and analyze data from existing Earth observation satellites, making real-time demands like timely disaster response impossible. Toward real-time analytics, we introduce OrbitChain, a collaborative analytics framework that orchestrates computational resources across multiple satellites in …

Hooked the tube amp back up after repairing a bad trace and checking some other soldered connections. It's still making noise in one channel, but it goes away after a little while and only reappears once in a while. I really missed having tunes, maybe I can live with it for a while...🫤🎶

Security and Privacy Assessment of U.S. and Non-U.S. Android E-Commerce Applications
E-commerce mobile applications are central to global financial transactions, making their security and privacy crucial. In this study, we analyze 92 top-grossing Android e-commerce apps (58 U.S.-based and 34 international) using MobSF, AndroBugs, and RiskInDroid. Our analysis shows widespread SSL and certificate weaknesses, with approximately 92% using unsecured HTTP connections and an average MobSF security score of 40.92/100. Over-privileged permissions were identified in 77 apps. While U.S. …

Bridging Control Variates and Regression Adjustment in A/B Testing: From Design-Based to Model-Based Frameworks
A B testing serves as the gold standard for large scale, data driven decision making in online businesses. To mitigate metric variability and enhance testing sensitivity, control variates and regression adjustment have emerged as prominent variance reduction techniques, leveraging pre experiment data to improve estimator performance. Over the past decade, these methods have spawned numerous derivatives, yet their theoretical connections and comparative properties remain underexplored. In this p…

Preserving Core Structures of Social Networks via Information Guided Multi-Step Graph Pruning
Social networks often contain dense and overlapping connections that obscure their essential interaction patterns, making analysis and interpretation challenging. Identifying the structural backbone of such networks is crucial for understanding community organization, information flow, and functional relationships. This study introduces a multi-step network pruning framework that leverages principles from information theory to balance structural complexity and task-relevant information. The fra…

Mean-field analysis of a neural network with stochastic STDP
Analysing biological spiking neural network models with synaptic plasticity has proven to be challenging both theoretically and numerically. In a network with N all-to-all connected neurons, the number of synaptic connections is on the order of $N^2$, making these models computationally demanding. Furthermore, the intricate coupling between neuron and synapse dynamics, along with the heterogeneity generated by plasticity, hinder the use of classic theoretical tools such as mean-field or slow-fa…

Some leftists have criticized #NoKingsDay2 as useless. Though it was the largest protest in US history, it didn't change anything. I would go further to say that protests like these generally won't change anything. Dictators aren't forced to step down by 2% of the population coming out for one day. If they're forced to step down by protests, those protests are sustained. They are every single day. They are accompanied by general strikes.
We've been watching that happen all over the world. Portland in 2020 gave us a taste of that in the US. The George Floyd Rebellion was the type of resistance that actually brings down dictators like Trump. Occasional protests, no matter how large, can simply be ignored. That is precisely the reason the US developed a militarized police force in the first place. You need more, more than the largest protests in US history, more than Occupy, more than the resistance of the 60's and 70's, more than, and different from, anything we've seen in our lives.
And yet... Each protest has grown, and grown bolder. Some have grown more persistent. If you think of protest as the path to achieve change, you will lose. It is not. But it is a path to escalate. Some people, some otherwise comfortable white folks, came out for their first time. Some people got pepper sprayed for the first time. Some people questioned authority, stood up for the first time, and have had an experience that will radicalize them for the rest of their lives.
Protest is not useful in and of itself. It is training. It's making connections. Authoritarian regimes rely on the illusion of compliance, so visual resistance does actually undermine their power.
Liberals like to teach that non-violence is all about staying peaceful no matter what, that there's some way that morality simply overwhelms an enemy. I remember reading Langston Hughes' A Dream Deferred in high school. I said it was a threat. My teacher said, "you're wrong, he was a pacifist." Pacifism is a threat. If you can spit at me, beat me, shoot me, and I will not move, if I have the strength to absorb violence without flinching, without even rising to violence, what will happen when you push me too far?
What happens to a dream deferred?
Does it dry up
like a raisin in the sun?
Or fester like a sore—
And then run?
Does it stink like rotten meat?
Or crust and sugar over—
like a syrupy sweet?
Maybe it just sags
like a heavy load.
Or does it explode?
For peaceful resistance to work, there must be ambiguity. It must not be clear if or when the resistance will stop being peaceful. Peaceful resistance with no possibility of escalation is just cowardice.
My critique then is not so harsh as some other anarchists. If you think that protest alone will work, you're probably going to lose. If you are prepared to escalate, if you are prepared to absorb violence without flinching, then it could be possible for protest alone to topple the dictator. The cracks are already beginning to show.
And then what?
The problems that lead to the George Floyd uprising were never resolved. The problems that lead to Occupy where never resolve. The DAPL was built, protesters were maimed, it leaked multiple times (exactly as predicted). Segregation never went away, it only changed forms. The fact that immigrants have different courts and different rights means that anyone can be arbitrarily kidnaped and renditioned to an arbitrary country. We never did anything about the torture black site. FFS, people can still be stripped of their voting rights and slavery is still legal in the US. The people who control both parties in the US are killing our children and grand children with oil wars and climate change.
Toppling the dictator does nothing to resolve all of the problems that existed before him.
No, #NoKingsDay was absolutely not useless. #NoKings and related protests are extremely useful but they aren't sufficient. But, I think we still need to challenge the movement on two points:
How do you escalate after you're ignored or brutalized?
What do you demand after you win?
