@qurlyjoe@mstdn.socialOur brains—as are all brains, really—are remarkably talented at discerning patterns in all of our sensory input, filtering and interpreting it all, and letting that interpretation guide our behavior. We’re pretty good at it, really. We need to see the patterns or we die. Are we the only ones who see patterns that aren’t really there, or that make shit up to support our misinterpretations? That would explain gods, religion in general.

@tiotasram@kolektiva.socialJust finished "A Psalm for the Wild-Built" by Becky Chambers. Overall it's good but I also have some Thoughts.
First, it was very pleasant to finally read some non-trite utopian solarpunk after having read stuff like Octavia Butler recently. Both hope and despair can be poisonous on their own IMO, so getting some balance in is nice. It's definitely a very valuable thing to be able to lay out an actually desirable and in many ways imaginable future given our grim present. Chambers is no LeGuin though. I'll probably be reading more of her work and maybe she fleshes out these ideas elsewhere, but at least in this book there is no focus on either how the transition to a better society could happen nor on how the better society holds up in the face of adverse events and inclinations. Compare LeGuin's "The Dispossessed" or N. K. Jemisin's short story "The Ones Who Stay and Fight" and it feels like there's something important missing from Chambers' portrait of a future society. Of course, maybe the point is to make a cozy book, in which case fine, there's certainly a place for such things, and I can look for deeper inspiration elsewhere.
The second big thought I had was that Chambers' worldview seems not well-informed by certain indigenous perspectives, and this creates some contradictions. For example, (minor spoilers) when Dex enters the wilderness there's a whole bit about understanding humankind's place in nature and how human settlements are what we're used to but they're only a brief interruption of the vast untouched wilderness. Along the same lines, much of the world is intentionally left untouched by humans as a way to keep it pristine and natural. Later however, a character makes the point that humans *are* animals. The indigenous perspective that I appreciate would agree with that, and would further question the value in distinguishing between human influence on ecosystems and influences that others have. More sharply, one might observe that there's a bigger difference between how different kinds of humans relate to and influence their environments than between how less-disruptive humans and various animals do the same: the strip-mine-operator vs. migrant tribesperson impact difference is probably much greater than the migrant tribesperson vs. beaver gap, for example. Rather than talking about limiting human disruption, then, as if all human-environment interactions are disruptive and must be minimized, we could/should be talking about how to create human societies that have beneficial relationships with their environments and acknowledging that we actually have many positive examples of that, both historical and contemporary. Chambers' utopia is a "humans dominate nature but restrain themselves so that their disruptions are minimal and thus nature can thrive" vision, but what I'd even more like to see would be a "humans study old ways and make new ones so that they can interact positively with ecosystems again" vision, including some of "here are the places that sometimes breaks down but also the patterns and institutions that ensure repair of those breakdowns and thus long-term sustainability."
Final big thought: Chambers' utopia is too homogenous for my tastes. Of course it's hard enough and valuable work dreaming up and sharing any utopia and Chambers' transcends triteness in a number of ways, so this criticism is a bit rude. But the single shared religion, lack of mention of conflicts around shared decisions, especially historical society-defining ones, and nagging questions like "what about the people indigenous to the now-uninhabited lands?" and "what about the indigenous peoples who weren't part of the factory-building societies?" leave me wishing for more nuance in this direction.
All in all: a good book, and I'm criticizing out of a place of appreciation, not scorn. I've got there sequel out from the library as well and will probably detour to a few other books but get to it pretty soon.
Sadly I don't remember who, but I got this one because of a recommendation on here, so thanks if you're someone who recommended it!

Abstract: LLM-based coding tools enable non-expert users to generate routine automation scripts that may enter enterprise workflows without meaningful security review. This study examines that risk directly. Code was collected from ChatGPT, Microsoft Copilot, and Google Gemini using identical prompts across three automation domains. Claude Code performed a standardized vulnerability review. Each identified vulnerability was scored using CVSS v3.1 and mapped to the OWASP Top 10:2021 and the MITRE ATT&CK frameworks. Every script contained exploitable vulnerabilities. Nine of the 17 identified vulnerability classes appeared in code from all three models, while 14 of the 17 vulnerability classes appeared in at least two models. The weighted CVSS scores across platforms differed by less than 10%. The risk is not tied to any particular model but rather to the task category. Organizations should therefore ask not which tool to trust, but instead whether LLM-generated automation code should be deployed without review.

@aredridel@kolektiva.socialFor those that don't know, I help run a large women in technology chat group on Slack. It's been going for 11 years now! (ask me for an invite if you want one and that's appropriate!)
It has deeply shaped how I think about technology, especially the social side. There is so much embodied knowledge in that community, it's amazing. And it's also such a window into how much the mainstream of technology writing is dominated by men. We talk about it differently! We're much more likely to be critical, and to be critical of the _structures_ in tech. Sometimes that comes off as kneejerk "Ugh BRIAN!" to some of the bullshit men to do women in the workplace, but also embedded underneath is an understanding of rarely-mapped power structures in the field. So much advice out there is written assuming that there is no dissent, no silent frustration, no quiet abandoning the job when the pressures are unresolved. And so much of the tech world, press and on social media alike, has no insight that this attrition even happens.
Women, collectively, though, understand it. We notice the patterns of promotions. We understand the way that if we're in our 40s, we're rather likely to have a manager who is a decade younger than we are, with no particular experience. We notice when men are lauded for spending time with their family instead of work on occasion, but women are expected to be present at all times and rarely seen positively for doing the exact same things.
And yet, any given instance is always shrouded in deniability. The pattern generally holds, but is this one my fault? Do I not measure up? Or is it sexism?
That's what these structures rob from us: we never have the clarity in feedback that it is accurate, that is us that must change. When we stick to our guns, are we being obstinate, or are we correct? That information is denied to us by sexism. It only becomes clear in aggregate, and even then it is very hard to find action to take on it except to acknowledge it and move on.
I don't think people talk about that ambiguity enough: we're always looking for the clear sexism, the man speaking over the women, the trading sexual favors for advancement, the clear pattern of pet-to-threat that so many women experience as they age or gain skill in the field. But the bulk of sexism that we experience is in the structural poisoning of feedback.

Abstract: The hydroelastic response of free floating viscoelastic covers is measured using Faraday waves on the surface of a vertically oscillated fluid layer. We systematically vary the thickness $d$ of the covers to investigate its effect on the hydroelastic dispersion relation, the damping and the isotropy of the waves. Compared to bare fluids, the wave patterns are disordered. Various methods are explored to define and analyze the wavelengths, the isotropy, and shape of the waves. We find a significant difference between the measurements and the theoretical dispersion relation. Over all thicknesses $d$, this is explained by an increase in the in-plane membrane tension, which scales with $d^{3/2}$. Covering waves also has a large efect on their damping. Only for thin covers ($d = 20\: \mu{\rm m}$) the onset amplitude (and thus the damping) can be explained by dissipation in the bulk and in the boundary layer of the water beneath the cover. The same was found for bare water due to the presence of an immobile surface layer. Lastly, we find a large effect of the membrane on the ampitude of the waves, which we attribute to nonlinear wave interaction.

@hex@kolektiva.socialI had an interesting chat with a friend who mentioned a book called "The Living Company." Apparently Shell was one of the few companies that saw the 1970's oil crisis coming and was able to adapt. They did it by talking to a bunch of people randomly about the future, identifying patterns, and coming up with possible future scenarios. They then formed clear plans for these future scenarios, where those plans would cover as many related scenarios as possible.
This was actually really familiar to me, though I hadn't read the book, because that's very close to what the Seattle GDC disaster prep committee did. We identified possible disaster scenarios, then identified preparedness steps that served multiple purposes. We got boxes of n95 masks in 2018 and 2019 for wildfire smoke and did a bit of work building box-fan air purifiers. Over the years we handed out these masks to houseless folks who were most exposed to the smoke. When the pandemic hit, we were able to take some of those boxes to first responders just as manufacturing in China dropped because of their lockdowns and as others started PPE hoarding. We focused on N95 because that was one of the overlap points between the unexpected but catastrophic "flu pandemic" that we knew was possible, and the regular "wildfire smoke" problem we were just getting used to.
The book sounds like it's at least partially influenced by cybernetics. There's this Dutch cybernetics connection that I haven't quite figured out. Anyway, this guy talked about how a company needs to be sustainable and all that. My dude, you worked for an oil company. That is categorically not sustainable. All this aside, I think there are a lot of things we can and should take from capitalists (or take back, in some cases). This practice is one of them.
So maybe get together with friends and talk about what you think might happen. We live in a world of crisis, so I'll always recommend disaster preparedness. But there's more than that.
What do you think will happen in the next 5 years?
Assuming that happens, what actions would you take to push that towards the most positive outcome?
I'm listening to Revolutions and reminded of how much effort monarchies put in to preventing revolutions. Corporations can be even more advanced in their planning and preemption. What would it look like if we planned like that?

Abstract: We revisit the role of higher-order unification in dependently typed languages and identify a fundamental limitation of existing pattern-based fragments: their inability to synthesize functions defined by case analysis. Even simple and ubiquitous constraints arising from type inference, particularly from use of induction principles, fall outside the expressive power of Miller patterns and their modern extensions. We observe that such constraints naturally correspond to definitions by dependent pattern matching. Motivated by this correspondence, we propose integrating dependent pattern matching into the unification process. We present a prototype implementation of a small dependently typed language that collects delayed unification constraints and resolves them via a pattern matching compiler. Our approach successfully infers solutions that are rejected by current systems such as Rocq and Lean, suggesting a new direction for unification that unifies type inference and pattern matching compilation.

@arXiv_csGT_bot@mastoxiv.pageShould Demand Models Incorporate Competitor Prices? Oblivious Learning and Algorithmic Collusion
Yuhang Wu, Assaf Zeevi

arXiv:2606.05363v1 Announce Type: new
Abstract: On a platform with many sellers, should a pricing algorithm explicitly model competitors' prices when learning demand? Classical learning arguments suggest an affirmative answer: ignoring competitors induces model misspecification and inefficiency. In contrast, recent work on algorithmic collusion suggests that strategic obliviousness -- deliberately ignoring competitor prices -- may facilitate collusive outcomes and improve profits. We study this modeling choice in a stylized competitive market with unknown noisy demand, in which multiple sellers repeatedly set prices and estimate demand via iterated least squares, and either incorporate competitors' prices into their demand models (informed) or ignore them (oblivious). We first show that, relative to a monopolist, an oblivious seller in a competitive market must explore more aggressively to compensate for the loss of dynamic competitor information. Building on this insight, we characterize market dynamics when all sellers are oblivious and show that prices converge to the competitive outcome under sufficient exploration, while a continuum of pseudo-equilibria arises when exploration decays. Analyzing the resulting price trajectories, we uncover an excursion phenomenon that gives rise to transient collusive patterns that dissipate as learning progresses. In markets with both oblivious and informed sellers, the informed strictly out-earn the oblivious. Read as a strategy game, the modeling choice has a unique Nash equilibrium: the all-informed market, in which prices converge to the competitive outcome efficiently. Overall, our results indicate that collusive patterns are not robust and are not sustained by oblivious modeling; therefore, incorporating competitor information, together with sufficient price exploration, remains a reliable strategy for sellers in competitive markets.

@cdarwin@c.imA strengthening El Niño could reshape U.S. drought patterns, potentially leading to persistent dryness in the Plains.
Experts are concerned that a "Super El Niño" could emerge, raising the possibility of a "mini-Dust Bowl" scenario.
El Niño typically shifts storm tracks, bringing wetter conditions to the southern U.S. but leaving northern areas drier.
While a repeat of the 1930s Dust Bowl is unlikely due to modern farming practices, prolonged drought …

@arXiv_physicsfludyn_bot@mastoxiv.pageHigh-Order ADER-DG Hydrodynamics with ExaHyPE: Implementation, Validation, and Astrophysical Benchmarking

arXiv:2605.17132v1 Announce Type: new
Abstract: We describe a high-order ADER-DG solver for the compressible Euler equations within the ExaHyPE framework. The implementation combines a high-order ADER-DG polynomial representation, a local space-time DG predictor, adaptive mesh refinement, and an a posteriori subcell finite-volume limiter. We test the code on a deliberately mixed set of one- and two-dimensional problems: a strong-shock Sod-type problem, the Shu-Osher shock-entropy interaction, the Woodward-Colella blast wave, a contact-driven vortex sheet, and a shock-interface interaction. The one-dimensional cases recover the expected Euler wave patterns and show clear order-dependent gains in smooth and oscillatory regions. The two-dimensional cases probe a different part of the method, namely contact preservation, shear-driven roll-up, baroclinic vorticity deposition, and Richtmyer-Meshkov-type growth. In these tests the high-order update gives the expected resolution away from discontinuities, whereas the subcell limiter keeps the calculation stable near shocks and steep interfaces. The resulting code provides a reproducible ExaHyPE implementation for idealised inviscid, non-relativistic flows in which shocks, contacts, and multidimensional interfaces are the dominant features.

@toxi@mastodon.thi.ngThree years ago, I was busy finishing Marblemania, an endless algorithmic/generative realtime animation piece inspired by marbling, using softbody physics (but no actual fluid sim) and with thousands of variations and stylistic options...

@aredridel@kolektiva.socialGreyed out options are more obvious when there's a false binary choice before you but they happen in all kinds of situations, our habits driving us to ignore good options. So many of them are based on social convention patterns we pick up that may not even be real rules.

@hex@kolektiva.socialThe whole #LLM ROI thing reveals something interesting. It's basically impossible to figure out the ROI of an LLM. That makes it impossible for bean counters to make a comparison between human work and LLM work, or human work without an LLM and LLM-assisted work, to determine if the incredibly high price is worth it. But it's also impossible because you can't measure the ROI of a human, especially for skilled labor.
You can't measure the ROI of a human, because managers have no idea what people do. There's an eternally expanding amount of work designed to address this problem. But no matter how closely people are surveilled, interrogated, analyzed, there's never any real answer.
I've talked in the past about in relation to medical care. One of the dirty secrets of hospitals is that they have no way to figure out how much individual treatment costs. It's easy to understand at scale. You can know exactly how much something costs society. You can even identify patterns, using public health models, and decrease costs for society by trying to get people to avoid risky behavior (stop smoking, use protection during sex, etc). But it is absolutely not possible, at all, in any way, to figure out how much a single visit costs. This is similar to the problem of predicting climate change vs predicting the weather tomorrow in Amsterdam at 15:00. One is possible, the other is simply not.
But what is becoming painfully clear now is that this is true *everywhere*. It's trivial to know how much an industry costs. It's possible to figure out it's ROI for society. It is not possible to figure out how much value any individual worker provides. LLM ROI and cost comparison is an instance of this larger problem.
This is a problem for capitalism because it shows that the fundamental assumptions behind capitalism, that product value and labor value are quantifiable, that people can actually make comparisons between competing products, etc, are completely bullshit. The capitalist apologetics that makes up so much of economics, the lies that are told that hold this system together, are crumbling before our eyes.
If you make a lot of money, it's because you've been lucky. You have the right social networks, you have become good at convincing people to give you money. There is absolutely no way to connect that to actually providing value to society. If you make a lot of money, internalize that. Understand that you are not special, and things can change. If you don't make a lot of money, it's not because you don't provide value. Don't forget that. The system is a lie built to destroy you. Don't let it.
The ideology is sick, something something time of monsters and all that, we are together in this dying machine. We need to understand the lies. Your value can never be quantified. The way we have always figured out how to do the right thing for each other is through each other. Social connection has always guided us. But now the most socially disconnected people on the planet have hijacked the system. They direct the resources of the world, and game the system to avoid personal responsibility.
We have to build a system where everyone is accountable. We can't use abstract numbers and lies to figure things out for us. We have to build systems around people and accountability. There is no other solution.

Yes, you can override it with an explicit `role` declaration, which will undoubtedly happen as devs choose keyboard patterns that don’t match the role.
But still neat.
