"But Wall Street professionals, like so many other ostensibly smart people, refused to see Trump clearly, mistaking his skill as a demagogue for wisdom as a policymaker. “I don’t think this was foreseeable,” a mournful Ackman posted on X on Monday. “I assumed economic rationality would be paramount.” What an odd assumption to make about a man who bankrupted casinos.
Berezin thinks Wall Street still hasn’t come to terms with the cost of the nascent Trump presidency. “I do think that at this point we might have passed the event horizon, meaning that even if Trump backs off from the tariffs, there’s been enough damage done to the U.S. economy, to the global economy, to investor confidence, consumer confidence, that we’re probably going to see a recession regardless of what happens,” he said.""

"despite the law being very clear, actually, a few very determined transphobes have crawled their way to the heart of the law like maggots in an apple. A system that has been working perfectly well since 2010 has now been unnecessarily tampered with – and Starmer has capitulated because he’s spineless"

Juno Dawson: I had gender reassignment surgery – then the Supreme Court said I wasn’t a woman
I have the same choices over my life and body that I would want for every single person on earth. I’m not trying to make a statement about what a woman is, I just want to be one, writes Juno Dawson – who appears on The Independent’s Pride list 2025

I built a solar #meshtastic node
Now, I need to find a place to put it

Unfortunately & conversely, this (below) is the same framing tech bros (and parts of the population) are finding so attractive to anthropomorphize LLMs: These are not machines, and them making mistakes is normal and expected... At the same time, the other card being played (by politics, military & law enforcement) is that AI-driven insights and decision making are _already_ considered superior, infallible and unchallengeable... in the middle of this two pronged rhetoric is the fate o…

Characterising the Standardisation Properties of Type Ia Supernovae in the z band with Hierarchical Bayesian Modelling
Type Ia supernovae (SNe Ia) are standardisable candles: their peak magnitudes can be corrected for correlations between light curve properties and their luminosities to precisely estimate distances. Understanding SN Ia standardisation across wavelength improves methods for correcting SN Ia magnitudes. Using 150 SNe Ia from the Foundation Supernova Survey and Young Supernova Experiment, we present the first study focusing on SN Ia standardisation properties in the z band. Straddling the optical …

I'm Sorry Dave, I'm Afraid I Can't Return That: On YouTube Search API Use in Research
YouTube is among the most widely-used platforms worldwide, and has seen a lot of recent academic attention. Despite its popularity and the number of studies conducted on it, much less is understood about the way in which YouTube's Data API, and especially the Search endpoint, operates. In this paper, we analyze the API's behavior by running identical queries across a period of 12 weeks. Our findings suggest that the search endpoint returns highly inconsistent results between queries in ways tha…

Multi-terminal Strong Coordination over Noisy Channels with Encoder Co-operation
We investigate the problem of strong coordination over a multiple-access channel (MAC) with cribbing encoders. In this configuration, two encoders observe independent and identically distributed (i.i.d.) samples of a source random variable each and encode the inputs to the MAC. The decoder which observes the output of the MAC together with side-information, must generate approximately i.i.d. samples of another random variable which is jointly distributed with the two sources and the side inform…

Type Ia supernovae
Type Ia supernovae (SNe Ia) correspond to the thermonuclear explosion of a carbon-oxygen white dwarf (C-O WD) star in a binary system, triggered by the accretion of material from another star, or the merger/collision with a secondary WD. Their phenomenal luminosity -- several billion times that of the sun -- has motivated their use as cosmological distance indicators and led to the discovery of the accelerated expansion of the universe. SNe Ia are also the main producers of iron and hence play …

CW-complexes and minimal Hilbert vector of graded Artinian Gorenstein algebras
I introduce a geometric interpretation of the set of standard graded Artinian Gorenstein algebras of codimension $n$ and degree $d$: the standard locus, which is a subset of the projective space of degree $d$ polynomials in $n$ variables, and I characterize it. Under opportune hypothesis, I prove that the locus of full Perazzo polynomials is the union of the minimal dimensional irreducible components of the standard locus and it is pure dimensional subset. On the other hand, I associate to any …

On the weak and strong Lefschetz properties for initial ideals of determinantal ideals with respect to diagonal monomial orders
We study the weak and strong Lefschetz properties for $R/\mathrm{in}(I_t)$, where $I_t$ is the ideal of a polynomial ring $R$ generated by the $t$-minors of an $m\times n$ matrix of indeterminates, and $\mathrm{in}(I_t)$ denotes the initial ideal of $I_t$ with respect to a diagonal monomial order. We show that when $I_t$ is generated by maximal minors (that is, $t=\mathrm{min}\{m,n\}$), the ring $R/\mathrm{in}(I_t)$ has the strong Lefschetz property for all $m$, $n$. In contrast, for $t<\mathrm…
