Been a minute since I lived there, but a few ideasβ€” Fairstate’s probably my favorite, mix of great IPAs and some odder (but well done) experimental-ish beers.

Also great are Lake Monster (a lot of really solid, more sessionable stuff), and Lynnlake (great at a lot of styles that I love for fall).

You don’t need to compile all your packages on Linux anymore :)

Check out pak/p3m, which has pre-compiled binaries: r-in-production.org/packages.html

Kevin Munger has both some great descriptive work and meta scientific argument articulating the value of descriptive work for fast moving topics like social media platforms in his book The YouTube Apparatus!

See also his temporal validity paper for an articulation of the metascientific point.

Pivoting slightly, you said β€œGod, what have I done?”, so you’re now a pink pony girl and you dance at the club.

The example that motivated this post was β€œmaking actually good simulation studies”, which I was lucky to get in grad school, but lots of folks didn’t it seems.

The Missing Semester of Your CS Education

So I was thinking about MIT’s β€œmissing semester” course (missing.csail.mit.edu) on skills needed but often not explicitly taught.

What are some stats/survey stats equivalents y’all find super important- that is, important for research/practice, not commonly classroom taught?

I appreciate the correction here- will say it’s very hard to be like β€œyep that’s fake news” when the real news is like β€œMusk pushes refugee status for white Afrikaners”.

Any chance you have a time series source handy? Or just tracking manually?

This is an absolute scandal.

Trump and Marco Rubio abandoned American workers and their families abroad, delaying waivers to provide for their safe return to the United States.

As these civil servants lost their possessions, housing, and money, Elon Musk was slandering them with bogus accusations.

Reminder that ipums.org has all the acs, census, CPS, NHIS, MEPS, and so much more. Bonus that it’s cleaned and harmonized in ways that make these data really easy to use in practice.

Depends on how much luggage, but probably subway unless time pressured/rather cost insensitive.

Also a great candidate for getting a nice walk in because that connection is a bit awkward.

AMFAR has published a report on how the foreign aid freeze affects PEPFAR, which actually still hasn't resumed.

They estimate that hundreds of thousands of people lose access to HIV antivirals and 1500 babies are expected to contract HIV β€” *each day* 🧡

Thanks very much to everybody who chimed in on this thread about attention --I wrote up some notes!

My conclusion from the discussion is that polisci should coordinate on an info board / faux feed design to study (probs v. heterogeneous effects on attention)

While I don't think maximum entropy makes for good priors directly (use weakly informative ones), reasoning about what's maxent for a parameter is a nice way to orient yourself in building priors in complex situations. "What's maxent here?" can be a good starting question in finding a better prior.

This post started with chasing down a footnote from @rmcelreath.bsky.social 's Statistical Rethinking about an example from E.T. Jaynes.

This was mostly a chance to go down a lovely rabbit hole about handedness of Kangaroos, but I also aim to make a point about maximum entropy.
