When we say "no, everything hasn't been digitized," I need you to understand that we really mean is that virtually nothing has been digitized. This is because the realm of primary sources that historians use is incomprehensibly large.

Whenever I start to think Bluesky is bad, I remember that brigading on old Twitter got way more personal, with a junior-high-school “let’s ruin her life” vibe that I rarely encounter here. Medievalists basically had to preface every post with “I, for one, welcome our public struggle sessions.”

This would be a great feature!

I love how much happier he is doing these silly mystery movies and seeing himself as a muppet than he was being James Bond

Exhausted economist technical rant: every time someone talks about a GPU or TPU or other unit of compute, their comparisons are trash unless normalized by BOTH sticker price for the chip AND energy consumption of the chip. Chip cost = fixed; energy = marginal cost.

Here's a quilt of Volume 4 of the Epstein document dump. Gives you a 10,000 foot view of the redactions. that's 2,704 docs.

“Hello, it's me, The Dean of Yale. I read your thesis, I think it could be a bestseller. Now you must decide between Yale and marrying the hometown barista guy.” It's the highest of high art. If you're an academic you need to watch it ASAP.

If you are a Swarthmore alum with a PhD in economics, finance or economics-adjacent field, can you let me know? Making a list

Lol

I THOUGHT THIS WAS A JOKE

A story I found about Haiti: In 1999, a group of Haitians were tired of political disorder and dreamed of a better life in the United States. So they built a small, 23-foot boat by hand using pine trees, scrap wood, and used nails. They called the boat "Believe in God."

In a boat powered by nothing but a sail, they somehow made it from Tortuga Island to the Bahamas (about a 90 mile distance). Then from the Bahamas, they set sail again. But a few days and some hundred miles later, their makeshift boat began to sink.

This year on Bluesky I wrote 914 posts and 1,496 replies. I received 24,863 likes, where 286 were for my most popular post, and apparently I love saying "paper" www.madebyolof.com/bluesky-wrap...

Ok I made this but now have to figure out how to roll this out so I don't spam too many folks and get a reasonable response rate...

The whole interview is a pretty great indictment of visuals and how we see people in the media writ large.

Harvard should be 100% put on blast for not being more aggressive about Summers’ ties to Epstein, but I can’t help but notice the similarities between this activity and the recording and publicizing done by right wing conservative groups in red states…

Green Arrow more than said "Fuck Ice" #GreenArrow #NoBorders #FuckIce #EmeraldArcher 1. This is how the story "Sanctuary" from Detective Comics #551-552 started. Back then was INS. The kid showed his passport after this, but his brother is not in the same situation.

Elon's little serfs are quite literally begging journalists to come back because every publicly available source of data shows people have fled the platform and young people won't use it. They are literally begging regular people to come back. Don't do it! It is a website by and for actual Nazis!

To thwart malicious prompts, large language models use filters that are smaller than the models themselves. Recently, the Turing Award-winning cryptographer Shafi Goldwasser and researcher Sarah Ball showed that this size disparity makes LLMs insecure. www.quantamagazine.org/cryptographe...

I’m 40 and barely read the whole books I was assigned in high school. I still like books fine!

I was also bored and pulled up the replication package. The results are quite sensitive in aggregate to needing the controls. Here's the replication of Figure 3, including the case w/o controls:

Um, ok... This paper forthcoming at the JOP provides evidence that rent control in Germany actually made tenants MASSIVELY *less* NIMBY. This result was in the opposite direction of the authors' pre-registered expectations. And the effect sizes are, truly, massive.

I ignored the strip.clip argument in #ggplot2 for way too long 😲 Combined with a small negative margin tweak, you can place facet labels inside each panel. A tiny trick that makes small multiples feel so much cleaner. 🔵 no manual coordinates 🔵 inherits theme styling 🔵 scales nicely when resizing

Super cool looking paper. I want to try to implement this! arxiv.org/pdf/2512.06607
