One can see the US middle-age total mortality disadvantage in the mid 20th Century, compared to e.g. IT and SE.

It has after that narrowed and then widened again (much due to different timings in IHD mortality decrease).

And she got ill too! I do not know whether this is business as usual during Winter Olympics (the one before, Bejing 2022, was clearly special because of the ongoing restrictions).

I have preliminary life table calculations for SE 2025, showing a continued increase in e₀ >0.2 years from 2024 (official tables should be published 24 March).

An old pattern (cf fig. 1, 2, 4 for Sweden early 1976 and 1983).

I så fall har man nog skapat artificiell näringsförsörjning för hjärnan, så den inte åldras och dör av vaskulär sjukdom (det framhålls redan i P.C. Jersilds roman 1980).

Kanske för min del (f. 1981) Rajiv Gandhi (1991). Möjligen Pakistans Zia-ul-Haq (1988), men där är det väl oklart vad som hände.

Influensa - bekräftade fall

Not much change in influenza A for the whole country week 8. Declining among children, but still high in older age groups.

And RIP, Birgitta Andersson!

The Slow Death of the Power User — fireborn

On a similar theme, but a (perhaps ironic) overstatement, that SSH ever has been such mainstream knowledge.

I have been interested in making these tables into structured data, and tested a bit with open weight models about a year ago, but the results were not that good. Maybe they have caught up.

Techies vs spies: the xz backdoor debate Diving into the dynamics of the brazen ploy to subvert the liblzma compression library.

They are, like many other foundational libraries, not “supposed to change much” (but may still need someone to take responsibility for occasional maintenance).
