Since it was relevant to a discussion I just had on here and is something most people probably haven't thought about much (unless you've taken one of a handful of philosophy classes), I thought I'd try to lay out a key piece of Descartes' Meditations (#philosophy

Abstract: Context. Brightest cluster galaxies (BCGs) host powerful active galactic nuclei (AGNs) and help regulate the heating--cooling balance of the intracluster medium. While radio-mode feedback is well established locally, its prevalence at intermediate redshifts remains poorly constrained. Aims. We investigate the incidence, accretion state, and host-galaxy properties of AGNs in BCGs in Sunyaev--Zel'dovich (SZ)-selected clusters at $0.3 < z < 0.8$, testing dependences on cosmic epoch, cluster mass, and dynamical state. Methods. We analyse 171 BCGs from the Atacama Cosmology Telescope SZ catalogue, combining Southern African Large Telescope spectroscopy, WISE mid-infrared photometry, and Rapid ASKAP Continuum Survey radio data with \textsc{X-CIGALE} modelling to derive stellar masses, star formation rates, and Eddington-scaled accretion rates. Results. Thirty-eight BCGs (22%) host radio-loud AGNs. Only two ($\sim$5%) are high-excitation radio galaxies; the remainder are low-excitation systems. Most AGNs have low Eddington ratios ($-3 \lesssim \log_{10}\lambda_{\mathrm{Edd}} \lesssim -1$), consistent with radiatively inefficient accretion. Accretion efficiency increases with redshift, while correlations with cluster mass and dynamical state are weak. Radio luminosity is independent of cluster mass. Compared to field radio AGNs, BCG radio-loud AGNs have similar radio powers but are hosted by galaxies $\sim0.8$ dex more massive. Conclusions. BCG radio-loud AGNs at $0.3 < z < 0.8$ are predominantly low-excitation, radiatively inefficient systems, indicating that maintenance-mode accretion was widespread in massive clusters ($M_{500c} \simeq 3.2 \times 10^{14},M_\odot$) by $z \sim 1$. Accretion appears regulated primarily by fuel availability and cosmic evolution rather than global cluster properties, while the cluster environment mainly sets the host-galaxy mass scale.

ResonaVis: Visualizing Interactive Music Data to Support Reflective Music Composition for Therapeutic Contexts

Abstract: Designing music for therapeutic contexts requires navigating complex relationships between musical structure and listeners' sensory responses, yet composers often lack structured representations of these interactions, relying instead on intuition. We present ResonaVis, an interactive visualization system that helps composers analyze interaction and audio data from prior sessions with children with Autism Spectrum Disorder (ASD), informing future compositions. ResonaVis integrates audio features and interaction logs to capture how children engage with layered musical compositions, representing this engagement through coordinated visualizations of temporal transitions, layer co-occurrence, rhythmic activity, and spectral characteristics. Rather than prescribing strategies or supporting therapy sessions directly, the system surfaces patterns in past session data to support data-informed reflection during composition. We evaluated ResonaVis through a mixed-methods study with eight music students and a follow-up case study with two experienced composers. Results demonstrate good usability (SUS = 72.23), exceeding benchmarks for early prototypes, and show that participants could identify interaction patterns, reason about layer relationships, and make informed compositional decisions with high perceived performance and low frustration. Confidence in interpreting interaction and acoustic data for ASD-focused composition increased significantly across multiple dimensions (p < 0.05), with qualitative findings suggesting a shift toward more adaptive, data-informed composition. This work contributes a visualization design space for therapeutic music interaction data, an integrated system for compositional reflection, and empirical evidence that visualization tools support analytical reasoning and confidence in data-informed creative practice.

Content warning: Sobre "devoradores de estrelas" (sem spoilers)

Acabei agora de assistir o filme "Devoradores de Estrelas". É bem legal, a animação e o drama ficaram muito bem feitos. Mas ainda prefiro o livro. O filme mostra muito pouco disso, mas a história original é cientificamente detalhada, com experiências sendo descritas de forma razoavelmente pormenorizada. Ficamos com uma sensação constante de acompanhar o dia a dia de um cientista avançando em suas descobertas. Isto desaparece quase totalmente do filme, embora ele tenha compensado be…

Just did very approximate calculations; with 10g of lithium per drone*, and assuming the Russian and Ukrainian drone efforts consume 5m units a year**, that'd be ~50 tons of lithium deposited into the environment per year, mostly within, let's say, 50km of the grey zone***. It's only about $20,000 / ton****, which means $1m of metal*****.
So to answer my own silly question: no, it won't be economically viable to scalp the top few inches of topsoil and extract the lithium from it.
* Roughly right for quadcopters / small FPV; larger and longer range ones will have more, so this is a bottom bound. (OTOH longer range UAVs will tend to use ICE kerosene rather than batteries
** Changing all the time as both sides try expanding production as fast as they can manage. Ua are scaling much faster at time of writing
*** Handwaving. Contact zone's hardly moved since early 2023; OTOH Ua are pushing range limits on small battery-powered form factor, saw a 60km claim for the Logistics Lockdown operation the other day
**** There was a big spike to the $70-8000 range in 2022; median price is closer to $10k than $20k
***** (IDK the chemistry but presumably it's in an exciting range of different compounds, depending on how many bits the battery was blown into, how hot / pressured the blast wave was a few tens of mm from the boom, what other stuff was in the vicinity that the lithium would combine with, etc etc.

I just watched the #BlackHat #OpenAI #HuggingFace talk (#OpenAI understands it themselves. However, emergence is still no indication of actual intelligence, and the talk is again ripe with anthropomorphism.
3. Yes, it is surprising and somewhat terrifying how good these LLM agent loops have become in finding and exploiting vulnerabilities. We are seeing a much stronger version of the earlier next-generation fuzzing leap in tool capabilities.
4. The comparison with fuzzing and other tools is important for another reason: #OpenAI conducted their experiments on the live Internet. No, forcing internal test runs to go through a proxy server is *not the same as running in an isolated environment*. If there is a connection to a live production system, it is by definition not an effective sandbox. What happened to people letting their cool new fuzzers run live on non-consenting production targets on the Internet back then? They were criminally liable. Why should #OpenAI not be held liable for any damages caused by their systems?
Just because you don't understand the complexity that you built doesn't mean you aren't responsible for what it does!
5. The agent loops first successfully started exploited their proxy server on May 26th, discovered July 4th-6th as active exploitation and takeover. Credentials were revoked and the proxy server patched. "At this point, AI training and evaluations resume."
WHAT THE ACTUAL F...? You discovered emergent behavior in your overly complex system that you didn't understand, saw active exploitation of your internal systems to an extent that they were owned with admin privileges, and your response was to patch the uppermost surface holes, and then continue letting the out-of-control complex system run and continue on the same course? You didn't think to, let's see, maybe stop or at least pause the highly irresponsible experiment while figuring out - in detail - what went wrong, why, and how to avoid the same thing happening again on a systematic level?
6. On July 8th, completely unsurprisingly, the LLM agent loops continue to do the same thing and find another surface hole that hasn't been patched yet to take over again. Why should this have stopped? You haven't done any root cause analysis on the system level. Why do you expect that the problem should have stopped?
7. It takes another 11 days to discover that this is happening again. So you turned the system that had broken something back on again without a detailed root cause analysis and then didn't even watch carefully? I can't even...
8. And no, the response is not to fight fire with fire. Complexity on the attacker side (#OpenAI is the attacker, not the defender - they are the guilty perpetrator, not the innocent victim of circumstance) should be fought with *reduced* attack surface on the defender systems. Adding LLM agent loops that the "frontier" companies themselves quite obviously have no control over to already brittle systems with the hope of auto-patching your way out of vulnerabilities does not seem like a wise course of action. You don't mitigate complexity with even more complexity. The next 2 years will be ... exciting - and your best bet is going to be to disable all dependencies and complex interactions that your production systems don't absolutely require.

Semi-subtoot: there's a certain kind of anti-genocide narrative that draws comparisons between the Gaza genocide and the genocide of Jews, queer, and disabled people during WW2, with an incredulous overtone, the subtext of which is: if the good nations invaded Germany to stop the Nazis' evil in WW2, it's hypocritical for this nations not to take action to protect Gazan civilians now. There are a couple of problems with this line of reasoning, but the most obvious from an anarchist perspective (which sees "good nation" for the oxymoron it is) is that it's ahistorical. The reasons for the various allies' entrance into WW2 are varied, but they weren't about good and evil, and in fact the full depth of the evils of the Holocaust *was not known* in allied countries until after the war. Nations never really do things to "fight evil" like some humans might; they always act out of a kind of (imperfect) self-interest. The motivations for many of the allies were simply "we don't want Germany to conquer and destroy us" (and the imperfection in that motive is amply evident in the appeasement that preceded the war). America was of course not swayed by that motive, and it was the Japanese that (thinking the issue would have to come to a head eventually and that a surprise attack was worth speeding it up) put America in a situation where it joined for similar reasons.
Why is this extra relevant right now? Because neither the US nor any European country is existentially threatened by Israel (or threatened at all in fact, quite the opposite they're all benefiting economically from the situation in Gaza). The lesson of history isn't "brave, good nations will stand up to fight against anyone who commits genocide or other major evils", it's "nations act in their narrow and twisted and often mistaken self-interest (the interest of the national entity, which is often counter to the interest of it's citizens), and they always mythologize their actions after the fact as having been a fight against evil, which sometimes by luck is partially true."
To double down on this point: in the European theater the U.S. war actions were pretty good overall, defeating an evil opponent through military force and being a fairly gracious victor to the civilian populations there. In contrast, in the Pacific theater the U.S. was one of two evil empires duking it out for global dominance at the expense of civilians on both sides. The Japanese empire was a vile regime and perpetrated horrors in China, Korea, and across southeast Asia. The U.S. was barely better, between Japanese internment camps at home, and mass targeting of civilians on Japan, both with the firebombing of Tokyo and especially the nuclear bombs dropped on Hiroshima and Nagasaki.
So if your model of how we stop genocide is "convince the good guys to invade (or exert political pressure) and save the day", your model is wrong. That's not what happened in WW2. I'm not confident I know the perfect solution, but I do think it involves a mass of people making increasingly disruptive protest so that the cost *to rich companies and thus politicians* of falling to intervene is too high to stomach. That's a large part of what succeeded in South Africa, for example. Thankfully, there is already a vibrant protest movement to end the genocide in Gaza, and even though they haven't been fully successful yet, I'm optimistic that as things naturally (and through hard work) fall apart for various fascists politically, that movement will be able to succeed.
