@kamstrup@fosstodon.org In Swedish, “grep” is a garden fork, used to dig into soil. One could see some connection there. https://sv.wikipedia.org/wiki/Grep

@nothacking@infosec.exchange Wrote this (Swedish) post about these trade-offs in 2017.
There is a reason why we already in the 1930s had started phasing out incandescent lamps for applications demanding more light, in favor of discharge lamps.

@infobeautiful@vis.social It does not have such high R₀ under normal circumstances (an infection with an R₀ of 2 in a homogeneous population would tend to infect almost 80 %). That estimate is taken from this specific superspreading event. https://doi.org/10.1056/NEJMoa2009040
Other R₀ estimates are clearly wrong too (e.g. it is not >2 for Ebola, and it is clearly >1 for rotavirus and seasonal flu, or they would die out).

Scan a QR if you access the website from another device (like the Swedish BankID and Freja ID apps)? But you must still have such a phone at hand, of course.

@hehemrin@mastodon.nu @kallekn@mastodonsweden.se @carl@heath.social Håller med er. Det är klart det kan bli svårt att som enskild ta steget att byta i en stor organisation (de kunde ha tryckt mer på just den punkten med nätverkseffekter). Men även där överdrevs som sagt svårigheterna (måste väl gå att skriva ut en PDF/A skapad från en ODT?).

Nice! If someone wants to try live-bootstrap with QEMU/bare images generated on a ZFS dataset (and possibly other CoW filesystems), there is a bug in the Python generator scripts which leads to corrupt images. I made a simple fix, which hopefully will be merged. https://github.com/fosslinux/live-bootstrap/pull/567

@kadin@mastodon.sdf.org This is also good, about different electric light sources. I probably first noted it about 2004. https://www.lamptech.co.uk/

Wrote a new post about a prediction of Swedish cause of death patterns I made 10 years ago, and about raw contra life table-adjusted ratios.

@peter@thepit.social Some cases mentioned in the article (the man aiming to kill Queen Elizabeth) also predate modern LLM-based bots.
