Divide that by ten, is my understanding...

FWIW, my understanding is that the amount of money that has actually been delivered is a lot less than the numbers that get announced.

So excited to share that I'm a Researcher-in-Residence @inkandswitch.com! I'll be hanging out with the amazing people there in my free time - can't wait to share what I've been working on 🥳

Jonathan was the architect of WorldWide Telescope project, which I was gifted to work on with him back 15 years ago. I'll also miss knowing he might sneak up on us at some meeting somewhere (he liked to appear unexpectedly). And he was one of those people with near boundless curiosity! Rest well. ♥️

Flying to Philadelphia this morning to attend US-RSE'25! Get in touch if you'll be there too.

JADES: An Abundance of Ultra-Distant T- and Y-Dwarfs in Deep Extragalactic Data Ultra-cool T- (T$_{\mathrm{eff}} \approx$ 500 - 1200 K) and Y-dwarfs (T$_{\mathrm{eff}}$ $\lessapprox 500$ K) have historically been found only a few hundred parsecs from the Sun. The sensitivity and ...

I wrote another paper! And yes it's about brown dwarfs wait don't go anywhere they're really neat

ADS has given astronomy THE BEST literature tools available anywhere. I almost never have to use the garbage that other academics have to suffer through (GoogleScholar, JSTOR, LexisNexis, WoS, PubMed...)

Literally anytime I have to interface with those tools I weep

The alumni of this program are a who’s-who across silicon valley. Suspect there aren’t many law students following me here but if there is one in your life who is interested in tech law, they should apply.

#SciX is created by the #ADS team & operates out of the Smithsonian Astrophysical Observatory under a NASA Cooperative Agreement. Created and developed by scientists, for scientists, SciX builds on decades of open research infrastructure and collaboration: https://bit.ly/CfASciXNews

We have lift-off! Science Explorer, or #SciX to its friends, is excited to be your new home for open, connected, and trustworthy science. Explore. Share. Discover at scixplorer.org #OpenScience #ResearchInfrastructure #SpaceScience #EarthScience #PlanetaryScience

The wait is almost over! In just 2 days, #SciX will redefine how we #share, #search, and #build #science. Because #ScienceShouldntBeSiloed! #OpenResearch #OpenScience #PoweringDiscovery #EarthScience #SpaceScience #PlanetaryScience

NSF Graduate Research Fellowship Program (GRFP)

New: After a long wait, the GRFP solicitation is live! Deadlines have been extended to early November, so applicants have a bit over a month to submit. www.nsf.gov/funding/oppo...

🔭 It's paper day! Today I'm sharing the latest in a series of papers looking at the weather on other worlds, in this case bringing you the weather report from a nearby T-dwarf, SIMP-0136. 🪐

🧵 to follow...

We are clear for launch in T-minus 5 days. Science is about to become even more connected. Are you ready for a new dawn of research discovery? #SciX

I think what's being indicted there is the use of a 19th-century definition of the word "liberal" that is, at the very best, extremely misleading in any discussion that aims to be relevant to modern politics

"I cannot bring myself to say anything negative about dead, notorious war criminal Henry Kissinger because he was nice about my Star Wars book" is pretty bad!

Life news -- starting Fall 2026, I'll be an Assistant Prof in University of Maryland, College Park's Astronomy Department!

I'll be starting up a lab to measure all the substellar cloud things 🌤️🪐✨ and continuing alllllll the atmospheric model things

A photo of a laptop keyboard with the attributes described in the skeet.

I generally like my new XPS 9640 but this keyboard is a crime:

- Virtual function/media key row, including Escape.
- No right Control key
- Trackpad surface and its edges are completely invisible

This is supposed to be a laptop for people who use computers seriously!!!

Screenshot of research.gov after logging in, showing link for "Prepare and Submit Proposals" on the left in a red oval.

Screenshot of "Prepare New Full Proposal" on research.gov, with "add a new role" and "NSF 22-621" circled in red. In order to see the listing of the NSF Astronomy and Astrophysics Postdoctoral Fellowship, one must change role to "Proposed Postdoctoral Fellow"!

NSF Astronomy & Astrophysics Postdoc Fellowship apps are OPEN! 🔭 However, app only appears on research.gov if your role "Proposed Postdoctoral Fellow"! Click "Proposals", "Prepare and Submit Proposals", then "Prepare New". If you do not see NSF 22-621, change role to "Proposed Postdoctoral Fellow"!

Grad student mindset: write the proposal in order to write the paper.

Faculty mindset: write the paper in order to write the proposal.

Or, as I now grasp: grad students occupy the producer role (C-M-C) and the faculty occupy the capitalist role (M-C-M') in Marx's model of commodity circulation.

For new readers, $5 will get you three months of access to the collaborative effort of more than two dozen sharp writers and editors on staff at Defector. defector.com/products

YouTube video by Peter Williams How to Release Tectonic Crates with Cranko

I made a quick video for my Tectonic co-maintainers going over how releases are made using the project's Cranko automation tool. If you're into release automation (AND WHO ISN'T?!), you might be interested to get a sense of how it works.
