RE: https://mastodon.social/@luckytran/116863488282016628 That's the boat Pete and Toshi Seeger used in their successful campaign to clean up the Hudson River and organize people to work for environmental justice. Everybody out on that water is benefiting in immediate and quantifiable ways from the "left-wing" "politics" of the Seegers. https://en.wikipedia.org/wiki/Hudson_River_Sloop_Clearwater #PeteSeeger #Clearwater

@samlitzinger@journa.host My memory is that the verb "to sink" follows the same pattern as "to sing". Would the NYT say "Pavarotti sang Puccini" or "Pavarotti sung Puccini" (yikes)? Of course, the past participle is a different matter: "Pavarotti has sung Puccini". https://englishverbs.net/verb/sink/ https://www.oed.com/dictionary/sink_v

@HopelessDemigod@mstdn.social As someone who did get a novice license at age 11 (KA6FDD) and did tinker with electronics, I agree completely. We need to regulate the exploitative systems and not the individuals. The everlasting shame of so-called "libertarians" is that they got this exactly wrong.

A new documentary on the Manis Mastodon is now available to watch:

https://vimeo.com/1152386250

The discovery of the mastodon bones and an embedded spear point meant that humans were living and hunting in the Olympic Peninsula earlier than had been thought.

@sarae @msbellows By "mechanism" do you mean the question about the origin of the spear point? ("Others are less certain about the human origin of the point as it is unusually thin and has not been smoothed.") Or the lack of a human encampment in the excavated area? All I know is from the sources I posted, which are a bit fluffy.

@adamgreenfield An album from 2023 that talks about ecological collapse as well as the pandemic and protests of 2020: https://kaceyjohansing.bandcamp.com/album/year-away It's also about our passivity ("Watch It Like A Show") in the face of disaster. The album is in the folk or soft rock genre, I guess, which can be as easy to dismiss as metal (for different reasons, maybe).
