Statement tonight from Alan Garber, 31st president of Harvard. Good for him. Good for Harvard. Good for standing up to defend "core values of American higher education." And (again) what about all those "Harvard about to cave" stories? Main point: Worth reading what Garber says.

If a few health professionals say something you don't like, all said it and we should destroy the CDC. If a few students say something you don't like, all higher ed said it and we should end academic freedom. If the president and his party does something, that's one guy spouting off, let it go.

Today's mission: Schneefernerhaus at the Zugspitze, Germany's tallest mountain, for a taping for an @artefr.bsky.social documentary. The name is sadly apt: "Schnee" (snow) is rather "fern" (far) these days, and the remaining glacier is slated to lose its status in the next couple of years.
