Brought the pup into the office today, before the storm arrives on Monday (both snow and start of semester)

No, that was the pre-nap treat. Now I need the post-nap treat.

Then I can take a nap.

Apparently the search filters in Amazon when looking at TVs really let you zero in on the voltage you want ;)
check boxes from amazon.com allowing you to specify the voltage. The 3 options are: * up to 118 V * 120 to 120 V * 121 V & above

Two people on opposite aisles of a bus. One is looking out the window at a cliff with the caption "things I have to do". The other has a beautiful vista with a smile on their face with the caption "things I want to do"

pynucastro can now plot the nuclear partition functions from @rauscherthomas.bsky.social 's work:

pynucastro.github.io/pynucastro/n...

#astrocode

ne20 = pyna.Nucleus("ne20")
ne20.partition_function.plot()
nuclear partition function of Ne20 vs. temperature. It is 1 up to a few x 10**9 K and then rapidly increases to > 1.e6 at 1.e11 K.

What do you mean the clocks changed? Dinner time is dinner time.

I'm seeing a 2x speed up with python 3.14 compared to earlier (in our CI tests for pynucastro):
A screenshot of the GitHub actions showing timings to run the python tests with python versions 3.10 to 3.14. Most versions take ~ 30 minutes, but python 3.14 takes 15 minutes

we show this plot of binding energy / nucleon a lot in Stars class, but ever wonder how to make it? Here's a notebook that uses pynucastro:

zingale.github.io/stars/notebo...

#astro
A plot of binding energy per nucleon, showing a curve that stars at 0 MeV at mass number 1 and increases steeply to > 8 MeV / nucleon in the iron-group and then slowly declines for heavy A

I like my plot of equipotentials a lot, but I can never shake the fact that @sabinastro.bsky.social calls it the Teenage Mutant Ninja Turtle plot...

zingale.github.io/stars/notebo...
a plot of equipotentials in a binary star system, showing the Roche lobes and Lagrange points. The green color scheme makes it look like a teenage mutant ninja turtle...

14 years ago we adopted our pup Luna. Such a good girl!

new in pynucastro -- you can now color nuclei by abundance and rates by reaction rate strength easily:

pynucastro.github.io/pynucastro/p...

combined with the ability to read simulation data from a plot file via yt, this makes it easy to show reaction flow in simulations.

#astro
a reaction network visualization showing the nuclei (represented as nodes) connected by rates (represented by edges). The color of the nodes indicates the abundance -- here He4 is the most abundant. The color of the edges represents the reaction rate strength, with 3 He4 -> C12 being one of the strongest rates.

an Indiana Jones meme saying "Boundary conditions. why'd it have to be boundary conditions?". In the movie it refers to snakes, not boundary conditions.

meme updated to reflect the google AI generated search answers
A simpsons image of radioactive man in a sea of radioactive sludge with "protective" goggles. It usually says "my eyes! the goggles, they do nothing", but now says "my search! the google, they do nothing."

I recommend this book:
fake O'Reilly book called "Exiting Vim, Eventually", with an Octopus as the cover art and the tagline "just memorize these fourteen contextually dependant instructions"
