I have a question for those who know #rust. When I went to school I learned Assembly, ANSI C, Java, and Perl (oh... and Mathematica, but I'm trying to forget it). Then I learned VB (later .NET), C , and Python on my own. I've never been a full-time developer, but I will pick up an occasional pet project. Nearly everything I've done in the last 10 years has been in python.
Should I learn Rust? Are there new #programming concepts? Are there other reasons, as am #infosec professional, that make it worthwhile to run to an "Intro to Rust" class?

Tiens, une statistique qui m'avait échappée: au Québec, dans plus de 60% des cas déclarés de #covid, ce sont des #femmes et cette année, c'est Š plus de 67% des femmes!
Hypothèse: c'est parce que nous sommes plus nombreuses que les hommes Š s'occuper des autres.

bad math, need better data
okay, so... the "bomb spike" is the graph of Carbon-14 relative to... C-12?
I guess I'm thrown off by units of pMC/percent. percent what?
globally: 50 tonnes
nuclear testing: 1.3 tonnes
ocean: most of it
soil/biosphere: the rest
atmosphere: 840kg
3,206,000,000,000 tonnes (CO2 in general) ... hold up I have to have my units wrong.... each ppm is supposed to be 7.82 gigatonnes and we've released 2400 gt max since 1850... does that mean it started at 806 gt CO2 in 1850 or did I mess that up?
is the graph relating a fixed baseline like 1950 or an ever changing %?
#Science #ClimateChange
also, the decrease is NOT due to decay, it's due to exchange w ocean/biosphere
like the Suess effect is just "carbon 14 gets diluted by human use of fossil fuels" (which seems depressing)
C14 is naturally produced in the stratosphere by cosmic ray neutrons at a base rate
nuclear power plants release C14 at night when plants aren't photosynthesizing

Thinking about ownership semantics for a planned refactoring of libscopehal to make heavier use of C smart pointers.
Instruments obviously have to have shared references to their channels.
Channels need weak references to their parent instrument, to prevent circular dependencies.
I'm still waffling over GUI elements, but I think we want shared references in most of the GUI long term (to enable a newly added node to exist in the filter graph dialog or a properties page…

I'm at a conference today up in Boston. Great content, but they do this speed dating thing with the vendors. Instead of walking up to their booth, you rotate around the room and get a pitch.
My favorite game to play is "stump the sales engineer". I got one today that was perfect. I said "if I have control A, B, and C, why do I need your product?" SE kinda looked up to collect his thoughts, then smiled and replied, "yeah well I guess not."
Great to win "stump the SE", but even better when the SE admits it and shakes your hand. I will definitely be buying him a drink tonight.

X-ray detection of astrospheres around three main-sequence stars and their mass-loss rates
Stellar winds of cool main sequence stars are very difficult to constrain observationally. One way to measure stellar mass loss rates is to detect soft X-ray emission from stellar astrospheres produced by charge exchange between heavy ions of the stellar wind and cold neutrals of the interstellar medium (ISM) surrounding the stars. Here we report detections of charge-exchange induced X-ray emission from the extended astrospheres of three main sequence stars, 70 Ophiuchi, epsilon Eridani, and 61…

Prix littéraires de la Ville de Québec: parmi les 12 oeuvres en liste, 7 ont été écrites par des femmes 🙂. Un phénomène toutefois m'étonne chaque fois, c'est la domination des hommes dans la catégorie des essais (3 nominations, 3 hommes). Je me demande bien pourquoi c'est comme ça, au-delŠ des prix littéraires de ma ville.

Dévoilement des finalistes du Prix littéraire de la Ville de Québec 2024
Québec, le 22 février 2024 – La Ville de Québec a dévoilé aujourd’hui les douze œuvres en lice pour son Prix littéraire 2024. Ce prix regroupe le Prix de création littéraire du Salon international du livre de Québec et de la Ville de Québec, le Prix de la poésie Jean-Noël-Pontbriand et le Prix reconnaissance en bande dessinée. Désignée ville créative de littérature UNESCO en 2017, la Ville remet ces prix qui soulignent la vitalité littéraire et le talent d’auteurs e…

Phonon softening and atomic modulations in EuAl$_4$
EuAl$_4$ is a rare earth intermetallic in which competing itinerant and/or indirect exchange mechanisms give rise to a complex magnetic phase diagram, including a centrosymmetric skyrmion lattice. These phenomena arise not in the tetragonal parent structure but in the presence of a charge density wave (CDW), which lowers the crystal symmetry and renormalizes the electronic structure. Microscopic knowledge of the corresponding atomic modulations and their driving mechanism is a prerequisite for …

Uncertainty quantification in $(p,n)$ reactions
Charge-exchange reactions are versatile probes for nuclear structure. In particular, when populating isobaric analog states, these reactions are used to study isovector nuclear densities and neutron skins. The quality of the information extracted from charge-exchange data depends on the accuracy of the reaction models and their inputs; this work addresses these two points. First, we quantify the uncertainties due to effective nucleon-nucleus interactions by propagating the parameter posterior d…

Imprinting of Antiferromagnetic Vortex States in NiO-Fe Nanostructures
Magnetic vortices are topological spin structures frequently found in ferromagnets, yet novel to antiferromagnets. By combining experiment and theory, we demonstrate that in a nanostructured antiferromagnetic-ferromagnetic NiO(111)-Fe(110) bilayer, a magnetic vortex is naturally stabilized by magnetostatic interactions in the ferromagnet and is imprinted onto the adjacent antiferromagnet via interface exchange coupling. We use micromagnetic simulations to construct a corresponding phase diagram…

Practical applications of machine-learned flows on gauge fields
Normalizing flows are machine-learned maps between different lattice theories which can be used as components in exact sampling and inference schemes. Ongoing work yields increasingly expressive flows on gauge fields, but it remains an open question how flows can improve lattice QCD at state-of-the-art scales. We discuss and demonstrate two applications of flows in replica exchange (parallel tempering) sampling, aimed at improving topological mixing, which are viable with iterative improvements…
