Niall Ferguson: Without Books We Will Be Barbarians
It is not the road to serfdom that awaits—but the steep downward slope to the status of a peasant in ancient Egypt, writes Niall Ferguson.

They tried to kill us (a missile hit like three blocks from us),
We survived (but are very tired),

After a massive Russian missile strike on Kyiv, teens waited 12 hours at the rubble of their friend’s home.
He was found dead.
Three children were killed in the attack.
One friend said simply, “He was good. I want people to know that.”

I’ve long used FiveThirtyEight’s interactive “Hack Your Way To Scientific Glory” to illustrate the idea of p-hacking when I teach statistics. But ABC/Disney killed the site earlier this month :(
So I made my own with #rstats and Observable and #QuartoPub ! stats.andrewheiss.com/hack-your-way/

It’s worth stating this simply: For literally anyone in the US Govt from 1945 to 2025, Signalgate would require an instant resignation—and a criminal investigation. It would be a matter of personal *honor* to resign. The fact Mike Waltz & Pete Hegseth are choosing to fight it out is a terrible omen.

Government spreadsheets sometimes add asterisks next to a few numbers in a large data set. Why worry about that when I can handle it automatically?
x <- c("10.1", "74%", "23*")
as.numeric(x)
[1] 10.1 NA NA
Warning message:
NAs introduced by coercion
readr::parse_number(x)

never to be forgotten..
8 February 1943 | A transport of 2,000 Jewish men, women, and children arrived at #Auschwitz from the ghetto in Białystok.
After arrival selection, 75 men and 95 women were registered in the camp. The remaining 1,830 people were murdered in gas chambers.
