Autism spectrum condition, attachment to objects, "minimalism"
I could say that I'm a minimalist. Much like many other of my characteristics, this one stems from the autism spectrum.
Many people in the spectrum show emotional attachment to objects. Sometimes you could think of it as "hoarding", but for me it's mostly about strong negative feelings when something breaks, when I need to throw it away (interesting enough, I don't really mind giving it away, so others could use it, just trashing).
The simplest way to limit these negative feelings… is to have very little stuff. Don't buy, nor take, stuff that you don't need. Limit yourself to things that are really important, and ideally wait some more, look around, maybe it will turn out you didn't need it after all.
I don't have any plushies (anymore). Most of my old hardware were given "into good hands". Some is still waiting for a good way how to revive it. There are no ornaments over my walls, just an old clock that belonged to my grandmother, one from the "сделано в СССР" era. Its scary how outdated my smartphone firmware is.
I suppose some people will think it's an unhappy life. I don't really know. I don't think I've ever enjoyed mindless consumption. Perhaps as a child — but the excitation of novelty usually quickly gave way to disappointment.
And gifts, gifts are something I truly hate. But it's a separate topic, another kind of trauma.

If you haven’t noticed that many of the big data breaches are now often via third parties then you aren’t paying attention. Third party risk is super high now. You need to pay attention to their cybersecurity now! infosec.exchange/@DevaOnBreach

I've long been fond of the phrase, "the bottom falling out of the bucket" as a reference in #Zen to a kind of irreversible awakening experience. It's used in the 12th c. *Blue Cliff Record.* This story appears to be from a century later, but it's nice (from Paul Reps' *Zen Flesh, Zen Bones*):

When the nun Chiyono studied Zen under Bukko of Engaku she was unable to attain the fruits of meditation for a long time.
At last one moonlit night she was carrying water in an old pail bound with bamboo. The bamboo broke and the bottom fell out of the pail, and at that moment Chiyono was set freel
In commemoration, she wrote a poem:

In this way and that I tried to save the old pail 
Since the bamboo strip was weakening and about
to break
Until at last the bottom fell out. 
No more water in th…

I honestly can’t read this without hearing the pulsejet of a V-1 flying bomb in my head, farting its way across the sky. 😂 thefolklore.cafe/@juergen_hube

We may not have Joe Bob tonight, but I am excited about tonight's movie with my discord friends. I think I've picked a fun one!

Pseudogap with Fermi arcs and Fermi pockets in half-filled twisted transition metal dichalcogenides

Abstract: Twisted transition metal dichalcogenides are a new platform for realizing strongly correlated physics with high tunability. Recent transport experiments have reported the realization of a Mott insulator, its bandwidth-driven evolution to a metal, and the strange metal behavior in proximity to the transition via the tuning of a displacement field in twisted $\mathrm{WSe_2}$($\mathrm{tWSe_2}$) fixed at half filling. However, the nature of the correlated states and the related Mott physics involved in the whole process remain to be determined. Here, we unveil theoretically the evolution of the ground state of the half-filled $\boldsymbol{\mathrm{moir\acute{e}}}$ Hubbard model as applied to $\mathrm{tWSe_2}$, transiting from a pseudogap state with Fermi arcs to a 120$^\circ$ Ne$\boldsymbol{\acute{\mathrm{e}}}$l ordered Mott insulator, then to another pseudogap state with Fermi pockets, and eventually to a Fermi liquid via a Lifshitz transition. The pseudogap phases are definitively identified by the vanishing of quasiparticle weights over an extended region of the free Fermi surface, with the remaining parts forming disconnected Fermi arcs or pockets that contain well-defined quasiparticles. The loss of quasiparticle weights in the pseudogap phases indicates the breakdown of Landau's Fermi liquid theory. We demonstrate that the emergence of the Fermi arcs/pockets results from the electronic structure reconstruction driven by strong electron correlations, marked by the existence of Luttinger surface enclosed by the zeros of single-particle Green's function. This work reveals the fundamental aspects of the Mottness in $\boldsymbol{\mathrm{moir\acute{e}}}$ systems and will stimulate the advance of the direct probes of the Fermi surface and quasiparticles beyond transports, such as angle-resolved photoemission spectroscopy (ARPES) and scanning tunnelling microscopy (STM) experiments.

Holla die Waldfee, weiss jemand was bei #autismusverstehen passiert ist?
facebook.com/share/p/A3E1UZr8j

Aufgrund unterschiedlicher Auffassung in Bezug auf die künftige redaktionelle Ausgestaltung des Magazins „autismus verstehen“ haben wir, die Redaktion des Magazins, die Zusammenarbeit mit dem herausgebenden Verein Autismus verstehen e.V. beendet. 

Daraus ergibt sich für Sie, liebe Leserinnen und Leser, folgendes:

1.
Das Redaktionsteam des Magazins „autismus verstehen“ wird ab Herbst ein neues Magazin in bewährter Qualität unter dem Namen „autismus magazin“ herausbringen.

2. 
Leider es ist es…
