Welp, from my PoV, all sides are wrong.
There is a difference between bug reports generated by AI to spam curl devs and AI generated bug reports sent by Google to FFmpeg devs that are accurate. Calling them slop is hardly true.
"We would rather not know there is a vulnerability in our software" is a terrible take.
Also, I would like to say that maybe it is unreasonable for a software with so little funding to want to support all codecs that were ever invented becaus…

Light-induced pseudo-magnetic fields in three-dimensional topological semimetals
In this work, we show that suitably designed spatially varying linearly polarized light provides a versatile route to generate and control pseudo-magnetic fields in Weyl semimetals through Floquet engineering. Within a high-frequency expansion, we derive an effective axial gauge potential $\mathbf{A}_5(\mathbf{r})$ whose curl gives the pseudo-magnetic field $\mathbf{B}_5(\mathbf{r})$. By mapping the light profile to $\mathbf{A}_5(\mathbf{r})$, we establish design principles for pseudo-magnetic …

"Just use cURL"
(article full of profanities)
https://justuse.org/curl/

This reads like a warning. So is cURL like nuts? Are people allergic to cURL!?
@… my watch might contain your software, maybe. They aren't 100% sure though. 🤷 🤣
[Note to reader, it almost certainly does contain cURL. I would be shocked if it did not!]

Curl Measure Fields, the Generalized Stokes Theorem and Vorticity Fluxes
We introduce and analyze the class $\mathscr{CM}^{p}$ of curl-measure fields that are $p$-integrable vector fields whose distributional curl is a vector-valued finite Radon measure. These spaces provide a unifying framework for problems involving vorticity. A central focus of this paper is the development of Stokes-type theorems in low-regularity regimes, made possible by new trace theorems for curl-measure fields. To this end, we introduce Stokes functionals on so-called good manifolds, define…

Spectrum of the Curl of Vorticity as a Precursor to Dissipation in 3D Taylor--Green Turbulence

Spectrum of the Curl of Vorticity as a Precursor to Dissipation in 3D Taylor--Green Turbulence
Predicting when a three-dimensional turbulent flow reaches its dissipation peak is essential for both theory and adaptive algorithms in simulations and experiments. Using direct numerical simulations (DNSs) of the Taylor--Green vortex (TGV) at resolutions of $256^3$--$1024^3$, we introduce and test a small-scale weighted diagnostic: the spectrum of $|\nabla \times \boldsymbolω|^2$ (with $\boldsymbolω=\nabla \times \mathbf{u}$), which, for incompressible flow, is equivalent to a $k^4…

See how tightly she has to curl up, there are too many people on her couch there’s barely enough space for Cat

i might be the only person in the world who wants cURL to PUT a 2 GB request* body to some URL, show progress while streaming, and do this with a `Transfer-Encoding: chunked` so that it doesn't buffer the entire stdin upfront

"Don't use curl -o /dev/null (or -o nul on Windows) because it's not portable, use curl -IXGET instead"
Can you imagine…
So out of morbid curiosity, what platforms is curl available on that don't have a /dev/null (or nul)?

ok took my medtimes
now I just gotta curl up and think warm thoughts

Captive portals, such a pain...
On ICE trains and in most places, it works fine.
I can open the portal and log in.
In the DB lounge, I can't open the captive portal login, in any browser.
It works on my phone though, so I use it as an access point as a workaround.
I can ping using domain names, includig my own servers.
curl says no route to host.
Fiddling with NetworkManager and systemd-resolved and dnsmasq and nsswitch... nope, can't figure it…

it's very funny to me that this is more efficient, letter-per-letter, than piping curl into bash

Every Fall I shake my fist at the guy who, back in the ‘40s, planted ( or left in place?) the majestic soaring silver maples that ring my home.
They are named for the way they look at this time of year, when the leaves curl and show their grey undersides.
The name oversells the look.
Meanwhile, the rest of my block is doing the red/orange/yellow display of other sorts of less-indigenous maple (and other trees. )

A Survey on the Div-Curl Lemma and Some Extensions to Fractional Sobolev Spaces
This survey is a chapter of a forthcoming book. This chapter recalls the classical formulation of the Div-Curl lemma along with its proof, and presents some possible generalizations in the fractional setting, within the framework of the Riesz fractional gradient and divergence introduced by Shieh and Spector (2015) and further developed by Comi and Stefani (2019).

Hodge Decomposition for Urban Traffic Flow: Limits on Dense OD Graphs and Advantages on Road Networks - Los Angeles Case
I study Hodge decomposition (HodgeRank) for urban traffic flow on two graph representations: dense origin--destination (OD) graphs and road-segment networks. Reproducing the method of Aoki et al., we observe that on dense OD graphs the curl and harmonic components are negligible and the potential closely tracks node divergence, limiting the added value of Hodge potentials. In contrast, on a real road network (UTD19, downtown Los Angeles; 15-minute resolution), potentials differ substantially fr…

An Improved Fit to the Density Distribution in Supersonic Isothermal Turbulence
The density distribution of supersonic isothermal turbulence plays a critical role in many astrophysical systems. It is commonly approximated by a lognormal distribution with a variance of $σ_{s,V}^2 \approx \ln(1 + b^2 M_{\rm V}^2),$ where $s \equiv \ln ρ/ρ_0,$ $M_{\rm V}$ is the rms volume-weighted Mach number, and $b$ is a parameter that depends on the driving mechanism, which can be solenoidal (divergence-free), compressive (curl-free), or a mix of the two. However, this neglects the cor…
