There was once a machine that told you "you want this" and "this is good." It said, "there can be no better system and it's foolish to try to build one." That machine has long since failed to function. Now you choke on fumes as it is consumed by the wild flames of an abandoned cause.
That machine could not possibly work anymore because the evidence of it's falsehood has become too overwhelming.
No, only abject terror now can keep you from plotting your escape, from creating an alternative. No, the illusion has long since broken. All that's left now is triggering fight, flight, freeze as hard as possible. Most will be paralyzed, and those who fight can be used as an excuse to escalate the terror.
These are the final stages of a dying sun, expanding and consuming it's children before the final supernova.
There is no longer a stable system, no longer a system with a future. All that remains is the spectacle that hopes to distract you long enough that you too can be consumed, that it may sustain itself a few moments longer.

I wonder how hard it would be to fabricate something that might (inadvertently, of course) disrupt the functioning of a drone that was, for instance, flying around a peaceful demonstration? I know it’s a federal felony (punishable by up to 20 years in prison) to shoot them down, or point a laser at them. But maybe something in a pocket, or backpack? So it’s not visible? #askingforafriend…

One first step people should do to respond to this is start using the “report a speed trap” function in Apple Maps to report where ICE is operating. Make Apple party to the attempt to protect people. https://www.theverge.com/news/791533/google-a…

Google removes ICE-spotting app following Apple’s ICEBlock crackdown
Google has removed Red Dot, an app people could use to report ICE sightings from Google Play, one day after Apple removed similar apps, including Red Dot and ICEBlock.

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?

Modeling Emission-Line Surface Brightness in a Multiphase Galactic Wind: An O VI Case Study
We present a fast and robust analytic framework for predicting surface brightness (SB) of emission lines in galactic winds as a function of radius up to $\sim 100$ kpc out in the circum-galactic medium. We model multi-phase structure in galactic winds by capturing emission from both the volume-filling hot phase (T $\sim 10^{6-7}$ K) and turbulent radiative mixing layers that host intermediate temperature gas at the boundaries of cold clouds (T $\sim 10^4$ K). Our multi-phase framework makes sig…

Etching-free dual-lift-off for direct patterning of epitaxial oxide thin films
Although monocrystalline oxide films offer broad functional capabilities, their practical use is hampered by challenges in patterning. Traditional patterning relies on etching, which can be costly and prone to issues like film or substrate damage, under-etching, over-etching, and lateral etching. In this study, we introduce a dual-lift-off method for direct patterning of oxide films, circumventing the etching process and associated issues. Our method involves an initial lift-off of amorphous Sr…

Warped products, solid hyperbolic fillings, and the identity $D^{1,p} = N^{1,p} \mathbb{R}$

Warped products, solid hyperbolic fillings, and the identity $D^{1,p} = N^{1,p} + \mathbb{R}$
We construct a large class of metric measure spaces $Z$ which satisfy the identity $D^{1,p}(Z) = N^{1,p}(Z) + \mathbb{R}$, i.e.\ any measurable function $u \colon Z \to \mathbb{R}$ with an $L^p$-integrable upper gradient is a constant term away from being $L^p$-integrable. To do so, we construct a family of hyperbolic fillings $\mathbb{H}_{α, β}(Y)$, $α, β\in (0, \infty)$, of a metric measure space $Y$, via a warped product of $Y$ with an exponentially weighted positive real line. We then s…

An iterative-bijective approach to asymmetric generalizations of Schur's theorem
In this paper, we present a new Rogers--Ramanujan type identity for overpartitions by extending the asymmetrical version of Schur's theorem due to Lovejoy to a broader class of infinite products. More precisely, we provide a combinatorial interpretation of the following product, for any positive integer $k$, as a generating function for a class of overpartitions in which parts appear in $2^k - 1$ colors: \[ \frac{(-y_1 q;q)_\infty \cdots (-y_k q;q)_\infty}{(y_1 d q;q)_\infty}. \] Our proof is b…

Tilted Dirac cones and their topology in Holographic Materials
We explore strongly correlated materials with tilted Dirac cone by introducing a method to realize this spectral feature within a holographic setup. Following the work by Moradpouri et al., we construct an asymptotically AdS spacetime by uplifting the vielbein of Volovik et al to tilt the flat spacetime light cone. We then couple the resulting metric to holographic fermions and compute their spectral functions, confirming the presence of a tilted Dirac cone in momentum space. We also calculate …
