ugh I will have to get into turning photos into videos won't I? Because this is fun but I NEED MORE COLORS.
dammit, I just want to look at pretty pictures. Pretty moving pictures maybe as it may be, but...
Anyway, if anybody here has experience and knows what the most pain free way is to turn a series of photos into a short video while using linux and not spending money, I'd appreciate advice (*from people with experience*) in this case.

My wife and I, we have very different philosophies about traveling.
She likes to visit places that she'd never want to live, just to briefly experience them and then come home.
I like to visit places specifically to see if I'd ever want to live there.

There are now exactly 365 posts on my blog. So, considering I've been writing it for twenty years, I have a long term average of one post every twenty days, over all that time.

Years ago, I moved to a place where I didn't speak the language. My initial strategy for dealing with interactions I didn't understand was to simply say "no." I figured this was safe - at least I wouldn't agree to something I didn't want. One day, as I was leaving my apartment with a friend, the guy across the hall asked me a question. "No," I said. He looked like I'd spit in his face then retreated to his apartment. My friend, dumbfounded, asked &quot…

Posted here the other day about getting a #pinephone, so I guess I should update. As I was half-expecting, it's not usable for me as a main phone (though I should still try LineageOS before giving up completely).
I had the Linux skills to hack through a lot of the problems that came up, but the shaky state of Android emulation meant I'd never be able to run key apps I wanted to, and the battery life is abysmal due to fundamental OS issues (plus probably some hardware stuff).
Still a super interesting platform and I've got ideas for uses besides being my main phone.

I mean, I get that circumstances change in life occasionally, but my first thought was, how'd they afford one in the first place? #Tesla

It was unavoidable that this week I'd end up writing about Apple's latest blunder. But in the context of Figma's Sites bullshit and Shopify recasting designers as "artists" it's even worse than one OS making a stupid decision.

As a Mass Effect aficionado It seems unfair to me that Shepard has a cabin full of cool ship models but I can't have any. Until now. Martin at printables.com posted an SR-1 3d model. My printer is single filament and low-resolution, so I had to do more work than him to pull it together. Plus painting PLA is a bit of a struggle. But now I have a model, however rough.
I'd still rather have what Shepard has.

Coherent states of finite-level systems
A method for constructing coherent states (CS) of finite-level systems with a given angular momentum is proposed. To this end we generalize the known spin equation (SE) to an infinite-dimensional Fock space. The equation describes a special quadratic system in the latter space. Its projections on $d$-dimensional subspaces, represent analogs of SE for $d$-dimensional systems in an external electromagnetic field which describe $d$-dimensional systems with a given angular moment.

There are two main reasons I'm not using GrapheneOS. The first is that I've had two Pixels die on me from hardware flaws, and so I think their hardware is complete trash. The second is that every time I see them talking, they're trashing some other free software project or (openish) hardware. Only _their_ platform is secure. I'm getting strong Theo De Raadt vibes from them, which is not the kind of thing I'd want to deal with.

In principle, I don't remove old contacts from my phone. I've figured out, if one of them ever calls me, I'd know who is calling.

Fundamental Limits of Learning High-dimensional Simplices in Noisy Regimes
In this paper, we establish sample complexity bounds for learning high-dimensional simplices in $\mathbb{R}^K$ from noisy data. Specifically, we consider $n$ i.i.d. samples uniformly drawn from an unknown simplex in $\mathbb{R}^K$, each corrupted by additive Gaussian noise of unknown variance. We prove an algorithm exists that, with high probability, outputs a simplex within $\ell_2$ or total variation (TV) distance at most $\varepsilon$ from the true simplex, provided $n \ge (K^2/\varepsilon^2…

Early spectra show CIII $λ$5696 emission like Type Icn SNe, shifting to Type Ibn features.

"[…] Wanting a man got me into awful troubles more than once. But wanting to get married, never! No, no. None of that for me."
"Why not?" Tenar demanded.
Taken aback, Moss said simply, "Why, what man'd marry a witch?" And then, with a sidelong chewing motion of her jaw, like a sheep shifting its cud, “And what witch’d marry a man?"
They split rushes.
"What's wrong with men?" Tenar inquired cautiously.
As cautiously, lowering her voice, Moss replied, "I don't know, my dearie. I’ve thought on it. Often I’ve thought on it. The best I can say it is like this. A man’s in his skin, see, like a nut in its shell." She held up her long, bent, wet fingers as if holding a walnut. “It’s hard and strong, that shell, and it’s all full of him. Full of grand man-meat, man-self. And that’s all. That’s all there is. It’s all him and nothing else, inside."
Tenar pondered awhile and finally asked, "But if he's a wizard—"
"Then it's all his power, inside. His power’s himself, see. That’s how it is with him. And that’s all. When his power goes, he’s gone. Empty." She cracked the unseen walnut and tossed the shells away. “Nothing."
"And a woman, then?"
"Oh, well, dearie, a woman's a different thing entirely. Who knows where a woman begins and ends? Listen, mistress, I have roots, I have roots deeper than this island. Deeper than the sea, older than the raising of the lands. I go back into the dark." Moss’s eyes shone with a weird brightness in their red rims and her voice sang like an instrument. “I go back into the dark! Before the moon I was. No one knows, no one knows, no one can say what I am, what a woman is, a woman of power, a woman’s power, deeper than the roots of trees, deeper than the roots of islands, older than the Making, older than the moon. Who dares ask questions of the dark? Who’ll ask the dark its name?"

We investigate space-time coherence in one-dimensional lattices of exciton-polariton condensates formed by fully reconfigurable non-resonant optical pumping. Starting from an open-dissipative Gross-Pitaevskii equation with deterministic reservoir kinetics and stochastic condensate noise, we derive a discrete complex-field model that incorporates coherent tunnelling, reservoir-mediated dissipative coupling and gain-saturation non-linearity.

MINDS: Detection of an inner gas disk caused by evaporating bodies around HD 172555
Mechanisms such as collisions of rocky bodies or cometary activity give rise to dusty debris disks. Debris disks trace the leftover building blocks of planets, and thus also planetary composition. HD 172555, a stellar twin of beta Pic, hosts a debris disk thought to have resulted from a giant collision. It is known for its extreme mid-infrared silica dust feature, indicating a warm population of silica-rich grains in the asteroid belt (~5 au), cold CO observed by ALMA, and small bodies evaporat…

masks at protests / demographics 2/n
I wonder about the influence of employment, as well. If you're at risk every work day, I could well imagine it seeming pointless to start being careful the rest of the time, and maybe just too cognitively dissonant to consider.
I remember in 2020, someone I knew was working at Waterstones, and they were forbidden to mask up at work - even though 2020 was before the whole "covid is over" thing.
I also remember reading about someone - maybe a nurse? that _kind_ of job, anyway - who'd started wearing a fitted mask while the default in their workplace was baggy blues, and iirc was formally rebuked. It wasn't allowed.
If for whatever reason you're unable to hold down a typical job, you might not have much cash for _getting_ things like masks, but you're also not under that same kind of economic pressure to put yourself at risk.

Saturable nonlinearity induced quantum correlations in optomechanics
We propose a scheme that induces quantum correlations in optomtomechanical systems. Our benchmark system consists of two optically coupled optical cavities which interact with a common mechanical resonator. The optical cavities host saturable nonlinearity which triggers either gain or losses in each cavity. Without these nonlinearities, there are no quantum correlations, i.e., entanglement and steering, generated in the system. By turning on the nonlinearities, gain and losses are switched on, …

Computing Diverse and Nice Triangulations
We initiate the study of computing diverse triangulations to a given polygon. Given a simple $n$-gon $P$, an integer $ k \geq 2 $, a quality measure $σ$ on the set of triangulations of $P$ and a factor $ α\geq 1 $, we formulate the Diverse and Nice Triangulations (DNT) problem that asks to compute $k$ \emph{distinct} triangulations $T_1,\dots,T_k$ of $P$ such that a) their diversity, $\sum_{i < j} d(T_i,T_j) $, is as large as possible \emph{and} b) they are nice, i.e., $σ(T_i) \leq ασ^* $ …

Finished "Far from the Tree" by Robin Benway last night. For me, it was a gripping and absolutely delightful read. I can recognize that I'm absolutely unequipped to judge whether it authentically reflects the experiences of many or few of the people whose situations are similar to the protagonists', but I find myself fervently hopeful for the former, even as I recognize such hopes in the part of people like me can be part of ultimately harmful publishing selection feedback loops. (If anyone reading this happens to have read the book and found it distasteful, I'd love to hear that.) Notwithstanding my probably overcautious uncertainty, I'll definitely be seeking out more books by Benway. At the very least, I really enjoyed her little joining and framing metaphors, and the pacing and plot construction were good, with lots of nicely interwoven implications arising through the buildup, and an ending that left me satisfied (albeit, I'm an inveterate optimist, YMMV).

Mixtures of nonhomogeneous viscoelastic incompressible fluids governed by the Kelvin-Voigt equations
An initial-and boundary-value problem for the Kelvin-Voigt system, modeling a mixture of n incompressible and viscoelastic fluids, with non-constant density, is investigated in this work. The existence of global-in-time weak solutions is established: velocity, density and pressure. Under additional regularity assumptions, we also prove the uniqueness of the solution.

Experimental observation of subabsorption
We predict and experimentally demonstrate a new type of collective (cooperative) coupling effect where a disordered atomic ensemble absorbs light with a rise-time longer (i. e., at a rate slower) than what is dictated by single-atom physics. This effect, which we name subabsorption, can be viewed as the absorptive analog of subradiance. The experiment is performed using a dilute ensemble of ultracold $^{87}$Rb atoms with a low optical depth, and time-resolving the absorption of a weak (tens of …

Random bipartite graphs with i.i.d. weights and applications to inhomogeneous random intersection graphs
We propose a random bipartite graph with weights assigned to both parts of the vertex sets. Edges are formed independently with probabilities that depend on these weights. This bipartite graph naturally gives rise to a random intersection graph which has nontrivial clustering properties and inhomogeneous vertex degrees. We focus on the situation where the weights are themselves i.i.d. random variables. In the so-called moderate clustering regime, we identify three types of scaling limit for the…

Remarks on $d$-ary partitions and an application to elementary symmetric partitions
We prove new formulas for $p_d(n)$, the number of $d$-ary partitions of $n$, and, also, for its polynomial part. Given a partition $λ(λ_1,\ldots,λ_{\ell})$, its associated $j$-th symmetric elementary partition, $pre_{j}(λ)$, is the partition whose parts are $\{λ_{i_1}\cdotsλ_{i_j}\;:\;1\leq i_1 < \cdots < i_j\leq \ell\}$. We prove that if $λ$ and $μ$ are two $d$-ary partitions of length $\ell$ such that $pre_j(λ)=pre_j(μ)$, then $λ=μ$.

Repeated ancilla reuse for logical computation on a neutral atom quantum computer
Quantum processors based on neutral atoms trapped in arrays of optical tweezers have appealing properties, including relatively easy qubit number scaling and the ability to engineer arbitrary gate connectivity with atom movement. However, these platforms are inherently prone to atom loss, and the ability to replace lost atoms during a quantum computation is an important but previously elusive capability. Here, we demonstrate the ability to measure and re-initialize, and if necessary replace, a …

Majorana Signatures in the Tripartite Uncertainty Relations with Quantum Memory
Quantumness imposes a fundamental limit on measurement accuracy. The paradigmatic cases are Heisenberg's uncertainty relation in the original formulation, Robertson's formulation, and improved uncertainty relations. However, the more universal measures are given in terms of quantum entropies. Uncertainties of measurements done on one quantum system correlated with another quantum system constitute a more intriguing question. Quantum correlations can influence the lower bound of uncertainties, a…
