New Gist: The Price of Ugliness
Jack Chambers wants to lower the aesthethic value of our entire public realm, as a matter of policy, because he thinks that will make it look like he is controlling costs.

Ghost-Free Quantisation of Higher Time-Derivative Theories via Non-Unitary Similarity Transformations
We address the long-standing ``ghost problem" in higher time-derivative theories (HTDTs), where quantisation typically yields sectors with either unbounded spectra or non-normalisable eigenstates; both rendering the theory unphysical. We propose a novel method that preserves the bounded nature of the spectrum in one particular sector while restoring normalisability by employing a non-unitary similarity transformation. Inspired by techniques from pseudo/quasi-Hermitian PT-symmetric quantum mecha…

This is cool: A user-defined string literal operator that turns string literals into their (compile-time) hash codes. Might be useful in some codebases to avoid having to maintain unique numerical values for a bunch of identifiers.
(But it might be that in large codebases, the time to run all these compile-time hash functions adds up to be unbearable.)
(I was specifically thinking of the "slot IDs" in

There was somebody fussing in my replies to my last link to my blog post about Medium (I don’t see them now; they probably blocked me, but their specific words don’t really matter), and the gist of their message was that they didn’t like that site. On the modern internet, if you have an issue with content written by humans, with no surveillance ads, that doesn’t allow AI scraping or AI slop content, with a business model that makes money… I don’t know how to help you. Honestly.

I’d rate myself an #AI skeptic to agnostic. I hadn’t used the tools at all, because I had problems w/ creation of the models: resource usage, & IP theft, were top of mind. Hallucinations a big issue too.
But I tried it, and even though I can’t set aside my concerns I’ll say I was impressed.
I used Claude to produce a Zsh prompt to replace one I’ve used for years using Oh My Zsh.

Quantum Assisted Ghost Gutzwiller Ansatz
The ghost Gutzwiller ansatz (gGut) embedding technique was shown to achieve comparable accuracy to the gold standard dynamical mean-field theory method in simulating real material properties, yet at a much lower computational cost. Despite that, gGut is limited by the algorithmic bottleneck of computing the density matrix of the underlying effective embedding model, a quantity which must be converged within a self-consistent embedding loop. We develop a hybrid quantum-classical gGut technique w…
