R.I.P. George Smoot, experimental cosmologist, Nobel prize winner and one of the discoverers of primordial fluctuations in the cosmic microwave background, a colleague and mentor back when I was a postdoc in Berkeley, always curious and enthusiastic.

macOS Tahoe/Safari complaint: in sidebar showing Tab Groups, current group shows tab list as if the disclosure triangle clicked.

Bad enough. But worse: old group in the sidebar stays open even when I click to a new one!

This seems so wrong that there must be a setting — but I couldn’t find it.

This seems like a whole mess of bugs. (Trying to update to macOS 26 Tahoe. Perhaps this is telling me it’s a bad idea?…)
