I wonder if you could use/abuse Mastodon polls (FEP-9967) to distribute posts that provide near-real-time status updates (I'm thinking about severe weather alerts but I'm sure there are other use cases)?

Create a poll with an expiry far in the future and a token set of options (ideally just one—"Do you opt in?"—but poll implementations seem to require at least two).

Nothing seems to prevent the content of a poll from changing—and this is the key insight. The FEP says, "The type of a poll (single choice / multiple choices) and its options might be changed at any time. In that case the author of the poll MUST reset the vote counts." So broadcast updates via the content.

It would be a lightweight way to follow a single item without following the actor, built on top of implementations that already exist. 

Cookie monster!

depth is kinda the forgotten dimension when buying rack-mounted computer equipment. if you're sticking it in a data center it's probably not going to limit you, but if you're like us and have a rack in your home, it's going to be the most significant constraint on what hardware you can use.

: Displacement, hunger and suffering

Young Palestinians collecting aid. Since Hamas’s 7 October attack triggered the Israeli army’s military response in the Gaza Strip, life – above all for children – has turned into a living hell. The Palestinian photographer Saher Alghorra vividly depicts their plight.

: The journey home

Going to school in Cape Town can be risky, because some areas of the city are controlled by armed gangs. This is especially true in the Cape Flats, a plain where notorious townships were established during the apartheid era. High youth unemployment contributes to gang-related violence. The British photographer Laura Pannack accompanied teenagers on their way home from school.

thinking about the time I ran a 2.5PB filesystem that was 18 racks of servers stuffed with 1TB disks. that much storage takes up about one quarter of one rack today.

: I hope your family is safe

Since the Ukrainian photographer Anya Tsaruk left her country – to go first to Poland and then Germany – she has repeatedly been asked if her family is safe. More often than not, she doesn’t know what to answer. What does safety mean since the Russian invasion? What is it like to live with the constant threat of drone and missile attacks? The danger is everywhere.

“월 700만원 보장하니 건설 현장이 달라졌다”···노동의 대가 ‘적정임금’ 안착될까 www.khan.co.kr/article/2025... "이런 상황에서 이 대통령은 지난 12월 9일 국무회의에서 “공공 분야가 모범 사용자가 돼야 한다”고 밝혔다. 기업들은 돈을 벌기 위해 법이 허용하거나 사회적으로 용인되는 범위에서 최저로 주고 이익을 최대화하는 게 이해될 수 있지만, 정부는 그래서는 안 된다고 지적했다."

Drawn blood and gore

I forgot to post about it, but last month I got the for “Slay the Princess” by @blacktabbygames, a 2023 game which btw is on sale right now: store.steampowered.com/app/198

The book is styled like a 250+ page choose your own adventure thing, with nearly all the artwork from the game plus WIP stuff and behind the scenes info. Great fun! 👍

This was a long preorder, but the second print run is still available: store.serenityforge.com/produc

Cover of the Slay the Princess art book. A large, wide format book with white lettering on a textured black background. The title is The Art of Slay the Princess, with credit to Abby Howard and Tony Howard-Arias. The cover artwork depicts the princess, contrasting in bright white against the backdrop, while a tall dark figure with gleaming eyes ominously appears in the background and seems to wrap the princess in large black wings. The art style is stylized, graphic-novel-like with anime leanings, slightly sepia-tinted black and white with sketchy lines and detailed shadows.Page 13 showing half a dozen character artworks, one with three variants, of the princess in a POV combat scene, kicking and throwing punches. She is fierce and menacing here. There are blood splatters, cuts on her body, and in some of the variants one of her hands is cut off. In the final image, she has a dagger sticking in her chest. The page contains dialogue quotes and narration from the game as well as artist commentary. A text box shows the choice-based structure of the book, directing the reader to page 34 from this one.Page 225, showing a different combat scene where the princess is still chained by her wrist, but turns the table on the main character, who is depicted in defense and overwhelmed. The princess cuts herself out of the chain (by cutting off her hand) and stabs the main character. The art and printed quotes frame her as heroic. There are several additional text boxes showcasing the multiple internal voices mechanic from the game, in this case including short quotes from the Voice of the Cold and the Voice of the Opportunist.Page 178, showing a wide illustration of a stone hallway staircase from the bottom. At the top of the staircase, the princess stands, gaunt, ghostly and distorted, holding an oil torch. In the printed dialogue, she muses about the building being their cause of strife before throwing the torch at the main character and lighting the room on fire.
