I wanted to share a side project I have been working on: CyRK github.com/jrenaud90/CyRK a #Python package that mimics much of the functionality of #SciPy solve_ivp but can perform #ODE integrations 100's x faster. If you are looking for a numerical integrator for your python project, check it out!
A black graph with white text. Y-axis is Average time; X-axis is number of required integration steps. There are several dots showing the performance of CyRK's cysolve_ivp, pysolve_ivp, and nbsolve_ivp functions compared to SciPy's solve_ivp. In all cases CyRK is significantly faster than SciPy. The plot shows the cysolve_ivp method to be the best in all circumstances.

I am losing my mind
Map of houses next to a 18 lane highway surrounded by parking lots and nothing to walk to in LA; houses cost at least $675,000 if not $800k+

My doctor's new registration portal has old English as a preferred language option. Excited to discuss my aliments Beowulf style.
A online form that has a drop down selection for preferred language. After typing the letters "e" "n" "g" the recommended options in the list are "English, Old (ca. 450-1100)", "English", "English, Middle (1100-1500)".

#Roman is starting to look like a real telescope!
The Roman space telescopes primary mirror apparatus and solar panels are sitting on the floor in a giant clean room at NASA Goddard. The Roman space telescopes main instrument package and superstructure is surrounded by engineers in bunny suites in a giant clean room. Behind the telescope is a huge wall of filters cleaning the air.

My hobbies have gone too main stream
Website ticket queue for the Maryland Renaissance Festival. The queue shows that I am in 5270th in line with 4885 people in front of me and over and hour wait to buy tickets.

Announcing you are cutting STEM education programs by including a photo of kids learning from said programs.

I feel like I am going to be sending a lot of these in the near future. Might as well help them remember me with some D&D stamps

At some point I signed up for Zillow reports for the White House. Got the 2025 update and it's dropped a lot in value. Still off the market

@wtyppod.bsky.social I am visiting your beautiful city (fish town) and our Airbnb has a gas heater right below particle board shelving. Will philly compensate my family when I die in the fire / carbon monoxide?
A gas heater very close to dry wood

Hey #AGU24 and #geophyscists out there come check out my poster next Thursday Afternoon "Influence of Bulk Compressibility on Tides in Rocky and Icy Worlds" (P43A-3002). I'll be talking about how this rock and this plot can tell us about the deep interior of #planets and #moons in our Solar System!

The colors get darker indicating a stronger signal to the right of the plot. Image credit: Joe Renaud

Hey #exoplanet community! NASA Goddard's Exoplanet Modeling and Analysis Center (emac.gsfc.nasa.gov) just joined. Nothing there yet, but consider giving it a follow! @exoplanetmodels.bsky.social
A logo spelling out "E M A C" short for NASA Goddard's Exoplanet Modeling and Analysis Center. The letters are floating in front of a sunrise on Earth as seen from the international space station.
