Watched a couple of episodes of #DeArktiskeReddere on DR (public broadcaster on Denmark) yesterday (series about #Greenland's search and rescue team - though they do a lot of emergency air ambulance type work too).
It's a really gripping and well filmed piece of work, sensitive on the difficult topics too and shows really well how different authorities work together.
I imagine it would be uncomfortable watching for USians who seem to imagine some kind of stone age society seeing healthcare emergencies dealt with so professionally with such excellent equipment (and for free at point of delivery).
I also find it hard to explain that the categories and separation between "Danes" and "Greenlanders" isn't always so clear cut and I think the programme got that over well.
It's filmed mostly in Danish but with Swedish, Norwegian and quite a bit of English, so may not travel easily but it's a really well done piece of TV and if you are at all interested in Greenland, it's worth seeking out.

We should not socially allow people to be entitled to feel upset about religious, cultural or any other non-inciting accessories peacefully, passively worn by others. Just imagine if it were banned to wear anything 🏳️🌈-coloured at work, in order “not to disrespect the heterosexuals” or to “maintain the separation of state and gender”.
(Non-medical face coverings are different, however. Public servants & the citizens they interact with should normally present their faces.)

@… the already improved UX looks good, to me.
When drafting a reply to a public toot, the word 'Public' is prominent (first screenshot).
When drafting a mention, the separation is clear (second shot).
Without being blasé about privacy: if a person accidentally publishes in either of those contexts, it's human error.
Lots of cloudy stuff in front of today's Bochum #sunset but the separation of a segment could be followed nonetheless - probably green but the color got lost. There is also a fresh contrail in front of the Sun; image sequence covering 4 seconds.
This becomes especially interesting when you understand the history of the church as a quasi-revolutionary organization. One could describe early church history as a mostly-successful attempt to overthrow the Roman empire. I say mostly successful because, in the end, the Roman state mutated the church for it's own ends and basically pulled a Lenin.
The early church was a religion of women and slaves that set up alternative institutions. See, the Roman economic system basically ran through the temples. Temples were basically the banks of their day (thus money changers in the temples and all that). So when the church set up their own institutions, they were actually attacking the economic system of the Roman empire. *That* is why the empire tried to destroy them. The Romans didn't really care about the gods. They would just mutate their beliefs to pull other pagans in. No, it wasn't about the gods. The Christian were fucking with the money.
The whole church as an institution was about dual power, and Paul (one of the early founders of the church) was central to organizing this into a political machine that could actually threaten the dominant order. One could argue that he saw the potential of the church, and used it to solidify his own power.
It all basically worked, right up until Constantine figured out how to flip the whole thing against the most radical elements. He had his people collect up different books of the Bible and modify them in such a way that it favored Rome. The trick here was to highlight the existing antisemitic threads of early church, and destroy the anti-Roman ones. Anti-authoritarian sects were killed as heretics, and centralized sects became aligned under the church.
This strategy of controlling internal dissent probably feels quite familiar. It's basically how the US works.
But this whole time, during the whole lead up to this, Christianity was illegal and it was continuing to grow as a system of dual power. When Romanism merged with Christianity, it created the most authoritarian institution in human history that brutally destroyed all opposition. Even still, several hundred years later it's power broke.
Today Liberalism has separated banking and the church, and has created the illusion of separation of church and state. But the same dual power strategy that allowed the first church to gain enough power to merge with the Roman power structure have now allowed Christian Nationalism to fully merge with Americanism into the Christian Fascism we see today...
Screening Workers with Affirmative Action

Abstract: This paper examines the optimal contracts in a two-dimensional screening model where one dimension(group identity) is verifiable by agents but not falsifiable. A principal offers contracts to agents who differ in cost types and group membership. Motivated by the United States Federal policy, Work Opportunity Tax Credit, the principal receives tax benefits for hiring agents from protected groups. Under the assumption that the protected agents tend to have higher cost types, the optimal contract induces full separation across both dimensions: agents reveal the cost type and the group identity through contract choice. Furthermore, the principal is willing to hire the trait agents with a higher cost threshold than the non-trait agents, and this threshold increases with the tax credit. Conversely, when the protected agents tend to have lower cost types, the optimal design without tax credits pools groups while separating by cost type. These results demonstrate that both affirmative action and non-discrimination can be optimal depending on the cost distribution ordering across groups.

It strikes me that #ICE is the clearest possible illustration of the importance of the principle of the separation of powers in a democracy.
The executive should not be empowered to directly control any agency which is capable of exercising deadly coercive force against citizens.

Just went through a code file and replaced "target" with "recipient" in a bunch of docs and variable names, because I had had two senses of "target" and because I want to encourage less-combat-focused thinking among potential devs (which at the moment and for the foreseeable future is just me). Zero changes to code functionality (unless I messed up) and took maybe 30 minutes. Got me thinking about the goal of software development and who would view that time as "wasted".
From a short-sighted "measure user-facing functionality" standpoint there was basically zero progress made. From a "cultivating-code-understanding-entities" perspective, there are both immediate and long-term gains. I got a chance to review the entire file at a high level which improves my understanding of things even if no changes had been made. The changes increase clarity of a lot of documentation, as well as variable naming clarity in code which deals with both senses of "target" which now has clear separation between variables that refer to targets and recipients. If there are any other devs in the future, this will help them a lot. Even if not, by increasing my own development efficacy, the expected values for project-gets-shipped and overall-project-impact just went up. I've also helped myself not introduce the same ambiguity in all my future projects, because I'll remember this time investment, and I've bent the ideological flavor of the protect towards neutral/beneficial interactions between "initiators and recipients" instead of hostile interactions between "initiators and targets".
Overall, well worth the time investment if we consider all the subtler benefits, and not just a very crude measure of user-facing behavior. (Secretly, this is also a post about LLMs.)

A Novel Explicit Filter for the Approximate Deconvolution in Large-Eddy Simulation on General Unstructured Grids: A posteriori tests on highly stretched grids

Abstract: Explicit filters play a pivotal role in the scale separation and numerical stability of advanced Large Eddy Simulation (LES) closures, such as dynamic eddy-viscosity or Approximate Deconvolution (AD) methods. In the present study, it is demonstrated that the performance of commonly used explicit filters applicable to general unstructured grids highly depends on the grid configuration, specifically the cell aspect ratio, which can result in poor filter spectral properties, ultimately leading to large errors and even solution divergence. This study introduces a novel, efficient explicit filter for general unstructured grids, addressing this shortcoming through a combination of a face-averaging technique and recursive filtering. The filter parameters are then determined through a constrained multi-objective optimization, ensuring desirable spectral properties, including high-wavenumber attenuation, filter-width precision, filter stability and positivity, and minimized dispersion and commutation errors. The AD-LES of turbulent channel flow benchmarks using the new filter demonstrate a noticeable improvement in turbulent flow predictions on highly stretched boundary-layer-type grids, particularly in reducing the log-layer mean velocity profile mismatch, compared to simulations using conventional filters. The analyses show that this enhancement is mainly attributed to the sufficient level of attenuation near the Nyquist wavenumber achieved by the new filter in all spatial directions across various grid configurations, among others. The new filter was also successfully tested on unstructured prism grids for the 3D Taylor-Green vortex benchmark.

Permeation of hydrogen across graphdiyne: molecular dynamics vs. quantum simulations and role of membrane motion

Abstract: Previous research based on electronic structure calculations and molecular dynamics (MD) simulations have demonstrated that graphdiyne (GDY) is a very suitable two-dimensional membrane for the separation of small molecules in a gas mixture of different species. However, quantum effects may play a role in the dynamics of these permeation processes when light molecules are the ones involved in the crossing of the GDY subnanometric pores. In this work we report rigorous quantum-mechanical calculations together with equivalent MD simulations of the transport of H2 molecules through a static GDY membrane, as a case study for the validity of the application to these problems of classical dynamics. The force fields employed are based on an improved Lennard-Jones formulation, with parameters optimized by means of accurate ab initio calculations. It is found that, although quantum effects are still significant at the temperatures of interest (between 250 and 350 K), MD simulations are able to reasonably reproduce the dependence of the quantum permeances with the temperature. Moreover, MD permeances computed with quantum corrections through Feynman-Hibbs effective potentials provide a lower bound to quantum permeances, while the pure classical counterpart gives an upper bound, thus leading to a well delimited range of confidence of the permeation results. Furthermore, within MD simulations it is possible to incorporate the thermal motion of the GDY layer and in this situation it is observed an enhancement of the permeances with respect to the fixed membrane case, due to a significant reduction of the permeation barriers when the GDY atoms are allowed to vibrate. It seems apparent therefore, that modeling the membrane motion is crucial to provide reliable simulations of the gas transport features.

Collective Electronic Polarization Drives Charge Asymmetry at Oil-Water Interfaces

Abstract: Why kinetically stable oil droplets in water spontaneously acquire a negative charge remains one of the most vigorously debated questions in interfacial science. Here, we combine neural-network based deep potential molecular dynamics with a data-driven and information theory approach to probe the real-space electron density at an extended decane-water interface. While decane-water clusters show nearly symmetric forward and backward charge transfer (CT) and thus negligible net CT, the extended interface displays a systematic electronic asymmetry, yielding a net CT from water to the hydrocarbon phase producing an average surface charge density of $\sim0.006~e^{-}\,\mathrm{nm}^{-2}$ on the oil phase. This imbalance is accompanied by much larger intra-phase self-polarization, particularly within the hydrocarbon phase, demonstrating that collective many-body polarization dominates the interfacial electronic response. Structural analysis reveals an asymmetry between forward C--H$\cdots$O and backward O--H$\cdots$C motifs, providing a microscopic origin for a net CT from one phase to the other. Curiously, both the water O--H and decane C--H covalent bonds incur subtle contractions which originate from a response to the charge-separation layers at the interface. These features are fully consistent with the weak improper hydrogen-bonds forming at the oil-water interface that results in blue-shifts of the C-H modes.
