Full disclosure in computer security still exists and is complementary to other disclosure models. The evolution of vulnerability disclosure is not linear from full disclosure to responsible disclosure to coordinated disclosure. These models coexist and all need to be taken into account.
You can’t just say “the legal framework will solve it” or “just do coordinated disclosure.” Vendors, researchers, and users are not all rational actors playing the same game.

In a rational world, this would torpedo any hope Newsome has for the Presidential nomination on account of how utterly stupid and ignorant it is.
If only we lived in a rational world.
Had to block like 3 people today already for having this unhinged opinion.
Of course they convinced themselves they're very normal and very rational people.
Medienkompetenz ist wichtig, da Parteien wie die AfD sich immer gegen Ereignisse positionieren und in jeder Darstellung ihre Ansicht als selbstverständlich, rational, oder normal darstellen, anders als alle anderen welche „ideologisch” oder „politisch” sind. Die AfD doch niemals!

A Modal de Finetti Theorem: Exchangeability under S4 and S5

Abstract: We introduce modal exchangeability, a symmetry principle for probability measures on Kripke frames: invariance under those automorphisms of the frame that preserve the accessibility relation and fix a designated world. This principle characterizes when an agent's uncertainty over possible-world valuations respects the modal structure. We establish representation theorems that determine the probabilistic consequences of modal exchangeability for S4 and S5 frames. Under S5, where accessibility is an equivalence relation, the classical de Finetti theorem is recovered: valuations are conditionally i.i.d. given a single directing measure. Under S4, where accessibility is a preorder, the accessible cluster decomposes into orbits of the stabilizer group, and valuations within each orbit are conditionally i.i.d. with an orbit-specific directing measure. A rigidity constraint emerges: each directing measure must be constant across its orbit. Rigidity is not assumed but forced by symmetry; it is a theorem, not a modeling choice. The proofs are constructive, requiring only dependent choice (ZF DC), and yield computable representations for recursively presented frames. Rigidity has direct epistemic content: rational agents whose uncertainty respects modal structure cannot assign different latent parameters to worlds within the same orbit. The framework connects probabilistic representation theory to the S4/S5 distinction central to epistemic and temporal logic, with consequences for hyperintensional belief and rational learning under partial information.

Already 6 years old, so not even taking into account post-2022 hyperscaling, this is a sobering, very rational and well argued 20 min presentation for some cold flush reality check of the hot fever dreams of AI proponents (and all YOLO energy/resource guzzlers of any walk/standing):

Trump bombardiert vielleicht noch ein bisschen mehr, einfach so. Trump will Kuba: "Ich kann machen, was ich will." Trump will Grönland.
Und jetzt will der Trottel auch noch Verstärkung, ausgerechnet von Dänemark und anderen NATO-Ländern für seinen Krieg gegen den Iran.
Rational ist das nicht mehr zu erklären. Warum immer noch dieses sanewashing eines gefährlich Durchgeknallten? Ja, hinter Trump stehen auch hochintelligente Überreiche wie Thiel. Aber ist Thiel vernünftig?…
Are governments properly supporting the digital commons? Many adopt open source software but don't fund the upstream projects that maintain it. This amplifies a "tragedy of the commons" rather than being part of the solution. Governments have historically invented ways to shape the playing field - patents, public universities, copyright, taxes ... They can do it again!

I would love it if we all took note of (and remembered) the following: the guy everyone knows is a sociopathic, purely self-interested, unrepentantly gleeful liar who is also visibly going through serious mental decline makes a long and incoherent speech without any indication that much of what he said is true in even the most cursory sense and traders say "yeah, good enough." Entrusting society's material future to the stock market is rational, ennit?

Minimal and intrinsic topologies on monoids of elementary embeddings

Abstract: To every $\omega$-categorical structure $M$ one can associate two spaces of symmetries which determine the structure up to first-order bi-interpretability: the topological group $\mathrm{Aut}(M)$ of its automorphisms and the topological monoid $\mathrm{EEmb}(M)$ of its elementary embeddings, both equipped with the topology of pointwise convergence $\tau_{\mathrm{pw}}$. We investigate the relation of $\tau_{\mathrm{pw}}$ to other topologies on these spaces: in particular, when $\tau_{\mathrm{pw}}$ is minimal, i.e.~does not admit any strictly coarser Hausdorff semigroup topology.
A common method to prove minimality of $\tau_{\mathrm{pw}}$ on $\mathrm{EEmb}(M)$ is to show that it coincides with the algebraically defined semigroup Zariski topology $\tau_{\mathrm{Z}}$. We show that $\tau_{\mathrm{pw}}$ differs from $\tau_{\mathrm{Z}}$ on $\mathrm{EEmb}(M)$ whenever $\mathrm{Aut}(M)$ has non-trivial centre. We then provide general conditions on the behaviour of algebraic closure on $M$ that imply minimality of $\tau_{\mathrm{pw}}$. These condition cover, for example, countable vector spaces and projective spaces over finite fields. Turning to $\mathrm{Aut}(M)$, we describe the minimal $T_1$ semigroup topologies on the automorphism groups of model-theoretically simple one-based $\omega$-categorical structures with weak elimination of imaginaries. We conclude by proving that the metric pointwise topology $\tau_{\mathrm{mpw}}$ is minimal, equals $\tau_{\mathrm{Z}}$, and is strictly coarser than $\tau_{\mathrm{pw}}$, on $\mathrm{EEmb}(M)$ for the real and the rational Urysohn space and sphere.

Speedability of computably approximable reals and their approximations

Abstract: An approximation of a real is a sequence of rational numbers that converges to the real. An approximation is left-c.e. if it is computable and nondecreasing and is d.c.e. if it is computable and has bounded variation. A real is computably approximable if it has some computable approximation, and left-c.e. and d.c.e. reals are defined accordingly.
An approximation $\{a_s\}_{s \in \omega}$ is speedable if there exists a nondecreasing computable function $f$ such that the approximation $\{a_{f(s)}\}_{s \in \omega}$ converges in a certain formal sense faster than $\{a_s\}_{s \in \omega}$. This leads to various notions of speedability for reals, e.g., one may require for a computably approximable real that either all or some of its approximations of a specific type are speedable.
Merkle and Titov established the equivalence of several speedability notions for left-c.e. reals that are defined in terms of left-c.e. approximations. We extend these results to d.c.e. reals and d.c.e. approximations, and we prove that in this setting, being speedable is equivalent to not being Martin-L\"{o}f random. Finally, we demonstrate that every computably approximable real has a computable approximation that is speedable.

Partial fraction decompositions on hyperplane arrangements

Abstract: We initiate the study of partial fraction decompositions (PFDs) in several variables using tools from commutative algebra. We give criteria for when a rational function with poles on a hyperplane arrangement has a desirable PFD. Our criteria are obtained by examining the primary decomposition of ideals coming from hyperplane arrangements. We then present an algorithm for finding a PFD that satisfies properties desired by physicists, and demonstrate the effectiveness of this algorithm for computing large examples coming from Feynman integrals.
