I don’t have much time in my life for fun hack projects these days, but I’ve always wanted to learn how custom Bluesky feeds work, so I managed to sneak some hacking in over the weekend while the kids were sleeping and built a “Found Haikus” feed: bsky.app/profile/dfm....

We're hiring Flatiron Research Fellows & Software Fellows at the @flatironinstitute.org CCA. These independent postdoc positions offer outstanding opportunities for collaboration, computation, and scientific growth in NYC: apply.interfolio.com/173402 apply.interfolio.com/173403

Now that I don’t work in astro research anymore (and because I’m on parental leave), it is time to retire from @joss-openjournals.bsky.social. It’s been an amazing 5 years supporting open source software in academic astrophysics, and I’m excited to see what the future holds for JOSS!

Applications are open for #FlatironCCA's 2025-2026 Pre-Doctoral Program. Participants will collaborate with scientists on a project complementary to their thesis for 4.5 months at the Flatiron Institute. Stage 1 applications due 3/14: www.simonsfoundation.org/flatiron-ins... #science #astrophysics

Hey bluesky! Do you want to develop your own open-source software in Python? Apply to attend Code/Astro! Website: semaphorep.github.io/codeastro/ Scroll all the way down for the application link. :) Apps are due Feb 1! (1/2)

Now that I write code as a full-time job, I didn't think I would do adventofcode.com this year, but I couldn't stop myself. I just finished collecting all the stars, and it was great fun as always! Thanks for the fun ride, @was.tl!

When my kid was born, we were gifted all of those "Science X for Babies" books (IYKYK), and at 1.5 he has decided that they are the only books we ever read just to spite us… At least he reaches for "Bayesian Probability" more frequently than "Astrophysics", proving that he's my child! 🤣

We @flatironinstitute.org are hiring a research scientist (open rank) at the CCA! Our priority areas are (1) plasma, (2) cosmological surveys, (3) stellar theory, (4) machine learning in astro, and (5) software & statistical techniques for astro. Reach out if yr interested! 🔭 aas.org/jobregister/...

Prompted by this and a need for distraction I Did Some Math. Turns out most extrasolar planets are quite cauliflower-compatible. A thread, with citations. And laboratory astrophysics. And footnotes.

Some news: in a few weeks I'll be leaving the Flatiron Institute to join Google DeepMind where I'll be working on the JAX core dev team. It's bittersweet to leave astro which (for better or worse) has defined much of my identity for the past 15 years, but I'm excited about new adventures!

Thrilled to announce an event I've long been thinking about! Join us at Yale University for a "Hack Day Conference," in which a group of educators come together to build resources and exercises for teaching research methods in astronomy. See astrocodex.github.io for more.

Delighted to announce that the inaugural New York Area Exoplanets Meeting (NYAEM) will take place at the Center for Computational Astrophysics (CCA) on May 30th, 2024! Abstract submission is open until April 5th, & registration until May 1st. Find more information here: nyexoplanets.github.io 🔭🪐🧪

Reposting for the weekday crowd!

I'm not on the astro lists here... Please share this there if you are. Thanks!

Applications are open for the pre-doc program at the CCA! This program is for current astro grad students to come visit NYC for 5 months and collaborate with a CCA scientist on a research project. I ❤️ this program so much!! Please apply and/or share! www.simonsfoundation.org/flatiron-ins...

just found a jar of jam in our cupboard with a best before date of Feb 2020. that jam really is from a different era!

Are you an astronomer or aspiring astronomer wanting to improve your software engineering skills? Applications for Code/Astro 2024 are open! More info at semaphorep.github.io/codeastro/. Application is linked at the bottom of that page. Apply by Feb 16!

Today's #AdventOfCode is coming for your Large Scale Structure research program! adventofcode.com/2023/day/11

adventofcode.com starts on Friday! 🚀 Advent of Code is a daily coding challenge Dec 1-25 that is fun in ways that I can't totally put my finger on. I normally use it as a way to learn a new language, but with a 5-month-old, I'm sticking to Rust again this time around: github.com/dfm/adventof...

I assume everyone deals with burnout by switching to a new code editor, right? [I'm going back to vim (actually neovim) after a few years in vscode land…]

My tutorial demonstrating how to implement custom C++ and CUDA ops for JAX (jax.readthedocs.io) was horribly out of date, but thanks to a few PRs it is now up to date with the current best practices: github.com/dfm/extendin...

Over at JOSS (joss.theoj.org) we're looking to recruit more editors in all areas! Check out the blog post for more info, and I'd be very happy to chat: blog.joss.theoj.org/2023/10/call...

super exciting that a potential 3rd transit of the elusive young planet V1298 Tau e was captured with CHEOPS, yielding a best-fit period of ~45 days! p.s. this is why I publish all data & models on GitHub, Zenodo, and use showyourwork! when publishing in AAS Journals

🤯

Speaking of hiring… don't forget about these two long-term astronomical software development roles with a deadline of Dec 1!

We're hiring postdoc fellowship positions at the Center for Computational Astrophysics! 3 year FRF: apply.interfolio.com/132546 5 year FSRF (focus on software development): apply.interfolio.com/132547 This is a great place to work & these are awesome jobs! Please share & reach out with questions!!

The 2024 Announcement of Opportunity for the NASA Hubble Fellowship Program (#NHFP) is now open! Interested scientists within 4 years of their PhDs should apply by Nov. 2; recommendation letters are due Nov. 9. Ask me if you have any questions! nexsci.caltech.edu/sagan/fellow...

I’m hiring PhD students and postdocs to my new extragalactic stellar streams group U. Copenhagen. Please reach out if you have any questions and share this if you know anyone who might be interested. PhD link: jobregister.aas.org/ad/e9fe0095 Postdoc link: jobregister.aas.org/ad/8218d16b

Over at JOSS (joss.theoj.org) we're looking for two reviewers for a submission of a Python package for ML classification of gamma-ray bursts observed with Swift. Any volunteers or suggestions would be appreciated! More info on the pre-review thread: github.com/openjournals...

I'm here now! Thanks for sharing Dan

The official version of the Annual Review "Gaussian Process Regression for Astronomical Time Series", by Suzanne Aigrain (who doesn't seem to be here on bsky) and me, is now published and available (open access): www.annualreviews.org/doi/full/10....

After spending some time coding in languages with sensible type systems, I always come back to my Python projects with such naive enthusiasm about Python types, just to be reminded what a world of pain they are, especially for scientific libraries! 😢

🚨 Awesome job(s!) alert!! 🚨 The Center for Computational Astrophysics is hiring two software engineers to work on supporting community software projects (& other fun things)! Check out @adrian.pw's thread for more info & please share with anyone who might be interested. I'd be happy to chat!!

My local pizza joint just became NYC's first unionized pizzeria!! Congratulations to the Barboncino staff - I can't wait to go for a celebratory dinner! 🎉🍕 https://www.nytimes.com/2023/07/26/dining/barboncino-brooklyn-pizza-union.html

The main reason I was still on Twitter was because of the NYCASP (NYC alternate side parking) bot, but now we have our own (unofficial) version skeeting here! Source code, for those who are interested: https://github.com/dfm/bsky-nycasp

A happy customer from the other one! The link is to https://dfm.io/posts/intro-to-numpyro/, which I am quite proud of…

👋 Hi! I'm Dan (you might know me as 🐦/exoplaneteer). I'm an astronomer in New York City who mostly writes code to help other people do astronomy. Find more info here: https://dfm.io These days I'm on leave, spending my time teaching my little one about underappreciated rock climbing techniques…
