It's barely October, for Christ's sake...

Apparently, I'm still in the top 1% of Java developers, which is surprising given how little Java I've been writing lately, mostly churning out C these days...

My dream job awaits on LinkedIn. I could be a cart attendant (wow!) at Walmart, and share the dream with the numerous other Caltech alumni who already work there. I wonder if they are cart attendants too...

Do astrometry calculations for thousands/millions/billions of stars or galaxies taking too long? Try SuperNOVAS. It's super precise AND up to 40000 times faster than astropy. #astrocode github.com/Smithsonian/...

Berman's was out of Sluice Juice today, so it's time to try something on the astronomical theme. Unfortunately, the contents are underwhelming but the name rocks anyway...

First summer storm of 2025 (Bonn, Germany).

Updated SuperNOVAS (v1.3.0-devel) benchmarks for calculating apparent positions for sources. It is 1,200 -- 30,000 times faster than astropy 7.0.0, and you could process the entire Gaia dataset (1.7 billion stars) in under 1 minute on a 16-core PC. #astrocode smithsonian.github.io/SuperNOVAS/

With SuperNOVAS you could calculate precise apparent positions for the entire Gaia dataset (1.7 billion stars) in under 1 minute on a run-of-the-mill 16-core PC. smithsonian.github.io/SuperNOVAS/
#astrocode

Here is an updated diagram of how astronomical coordinate systems are related, and what SuperNOVAS functions can convert positions and velocities among them. The dotted lines indicate possible loss of precision due to the inadequacy of the old (Lieske et al 1977) nutation model. #astronomy

Astronomical coordinate systems can be daunting. But here is a diagram that shows how they are related and the functions in the SuperNOVAS C/C++ library, which can convert among them. #astromethods github.com/Smithsonian/...

The fields around our home in Bonn / Bad Godesberg, around the first of February... This is my goodbye to frigid winters (at least for now...)

Amazing stuff. Sake flavor in vodka strength. Here comes Happy! 🍽️

It's about time for my fav Octoberfest brew

My 3rd attempt at Okonomiyaki pancake. Tweaked a recipe to (a) use what I readily had, and (b) keep it light without ending up with a runny a batter. The original recipe is here: www.justonecookbook.com/okonomiyaki/
(And my adjusted version in the comments...)

This is how you cook goulash. This one I made in Irvine, CA a few years back. And if you want a proper recipe check out the acknowledgement section of my PhD thesis: thesis.library.caltech.edu/2400/1/thesi...

nom.tam.fits version 1.18 is out. It is a 100% Java library for reading/writing FITS files, providing full (and fast!) support for the FITS 4.0 standard for Java developers (also available on Maven Central). github.com/nom-tam-fits...
