VBARE: A simple alternative to Protobuf & Cap'n Proto for schema evolution
At Rivet, we're building an open-source alternative to Cloudflare Durable Objects — a tool for running stateful compute workloads. VBARE is a small but crucial component in meeting the demanding performance requirements of Rivet Actors.

Active region upflows in various coronal structures and their coupling to the lower atmosphere
Plasma upflows with a Doppler shift exceeding -10 km/s at active region (AR) boundaries are considered potential sources of the nascent slow solar wind. We investigate the driving mechanisms of a pair of coronal upflow regions on the western and eastern peripheries of an AR, which have different magnetic topologies and surroundings. It is aimed to explore how these upflows couple to the lower atmosphere. Using observations of the Fe XII 19.51 nm line from Hinode, we identified two upflow region…

In case you ever wondered how album covers are embedded in audio files:
MP3 supports it since ID3v2.3. The "attached picture" frame can have one of 20 predefined types. (Front, Back, …)
FLAC has a METADATA_BLOCK_PICTURE which has a very similar structure to the ID3 tag. It supports the same 20 types.
OGG only supports it indirectly through VorbisComments. Convention is to use the FLAC format, but Base64 encoded.
AAC only supports it through a video stream.…

Parallel Nested Slice Sampling for Gravitational Wave Parameter Estimation
Inferring parameters and testing hypotheses from gravitational wave signals is a computationally intensive task central to modern astrophysics. Nested sampling, a Bayesian inference technique, has become an established standard for this in the field. However, most common implementations lack the ability to fully utilize modern hardware acceleration. In this work, we demonstrate that when nested sampling is reformulated in a natively vectorized form and run on modern GPU hardware, we can perform…

Thermodynamics in a split Hilbert space: Quantum impurity at the edge of the Heisenberg chain
We study the isotropic spin-$\frac{1}{2}$ Heisenberg chain with a single edge-coupled impurity of arbitrary exchange strength $J$. The model exhibits four impurity phases. For antiferromagnetic couplings ($J>0$): a \textit{Kondo phase} at weak $J$, where the impurity is screened by many-body excitations and the impurity entropy decreases monotonically from $\ln 2$ at $T \to \infty$ to $0$ at $T\to 0$; and an \textit{antiferromagnetic bound-mode (ABM) phase} at strong $J$, where the impurity scr…

Just read this long post on "the current state of Cara" https://cara.app/post/2e0d29d3-a57a-4b70-b0d0-9cefc15176ca

About the current state of Cara— Hi all, I’d like to address some users' concerns about Cara’s stability, algorithms and reach, and why we don’t actively promote Cara and recruit new users. I have touched on most of these before through other posts, but I’ll like to go over the main points and put them in one place since they often come up as recurring questions: — Cara’s longevity/stability > "A few weeks ago, after learning how much Jingna was struggling with her personal l…

A proud achievement of my half-century IT career happened in 1996 consulting to the #UNDP toward the first published edition of the Humanity Development Library.
It seemed easy enough: "It can be fairly estimated that 1/3, or about 20 million pages of UN, and as much University and NGO material are very useful. Those 20 million pages useful UN publications probably contain about 50% of solutions for major World problems. This information must be released in digital format for non-profit redistribution in all countries."
also portable and accessible to all platforms, everywhere.
Happily, not only did the project live on, but thanks to @… our once-intractable problem of global delivery is now globally solved!
So, whether or not this is timely, I don't know, but should you need to suddenly rebuild some semblance of civilization from scratch…

Runaway origins of a disc mass gradient in $σ$ Orionis
Radiation from massive stars is known to significantly affect the evolution of protoplanetary discs around surrounding stars by driving external photoevaporative winds. Typically most studies assume that the massive stars driving these winds are comoving with their associated clusters. However, it is also known that massive stars can be runaways, after being violently ejected from their birth environment through interactions with other massive stars. In this letter, we show that the well studie…
