All 26 items, newest first, in 8 years, generated when this page was built from the facts they announce rather than from a second set of files written by hand. Filter by kind below — it is a radio button and a stylesheet, so it works with JavaScript off. 9 further facts could be announced but carry no defensible date; turn inspect sources on, in the bar above, to see which — and to see the exact record every item below was generated from.

26 announcements in 8 years, read at build from content/cv.yaml, content/publications.bib, content/talks.bib, content/posts/**/*.{md,mdx}. A fact is announced on the date it carries; an announced key is written onto a fact only where the announcement happened on a date the fact does not otherwise state. Dates are shown at the precision the source states and no finer, so an item shown as a year is one whose source records only a year.

3 books, 3 outreach, 2 appointment, 2 editorial, 2 fieldwork, 2 journal, 1 award, 1 conference, 1 data, 1 invited keynote, 1 leadership, 1 oral presentation, 1 poster presentation, 1 project, 1 software, 1 talk, 1 under review, 1 writing. The filter above is one radio input per kind and one generated CSS rule per kind; the kinds themselves are the ones the records state — a CV section's own name, a talk's note field, a bibliography section's short name.

9 announceable facts carry no defensible date and are listed below rather than given an invented one. They are not missing from the site: a manuscript under review is on/publications/ like any other entry.
