Astral Codex Ten’s Open Thread 454 is a weekly forum for readers to discuss any topic, accompanied by several community notices. The post points readers to an updated BYU meetup listing, translated Fatima documents, earlier book review contest reviews and a physician-focused AI safety group; the author also says recent busyness has limited new posts.

Astral Codex Ten has published Open Thread 454, its weekly space for readers to discuss any topic, alongside notices about an updated Brigham Young University meetup, newly translated Fatima documents, archived book reviews and a physician-focused AI safety group. The post also says the author has been busy and has recently written less than planned.

The thread invites readers to post about anything or ask questions. The post points to the blog’s unofficial subreddit, Discord server, bulletin board and in-person meetups around the world. It says most of the blog’s content is free, while some is available only to subscribers. The thread functions both as an open-ended discussion space and as a place to share practical notices with the readership.

One notice concerns Effective Altruism college meetups: the post says Brigham Young University has changed the time, date and location of its meetup and directs readers to check the meetup list for details. It does not give the revised schedule in the thread itself. Another notice credits reader Nikita Sokolsky with obtaining additional documents from Portugal relating to Fatima and translating them into English. The post directs readers to fatima-1917.com and thanks Ana for work that required Portuguese proficiency.

The thread also links to epub collections of past book reviews, assembled by Rob Ennals, who created the site for this year’s book review contest. It notes that Physicians For AI Safety wants to make physicians interested in AI safety aware of the group and its open letter, which eligible readers can sign. The author apologizes for publishing little recently and missing Friday’s book review entry, attributing the lapse to being busy and saying they will try to make up for it when circumstances change.

Meetups, Documents and Reader Resources

The notices give readers several ways to take part in activities linked to the blog, including local meetups, discussion forums and a public letter aimed at physicians interested in AI safety. The BYU schedule change has a direct practical consequence: readers relying on an older listing may need to check the current one before attending.

The Fatima documents and book review epubs also make material available beyond the original post. English translations may help readers who do not read Portuguese access the documents, while the collected reviews put earlier contest writing into downloadable form. The thread does not describe the documents’ contents or the reviews’ scope, so readers will need to visit the linked sites for those details.

The author’s note about a slower publishing pace gives readers a limited update on the blog’s recent output. It is a statement about the writer’s workload, not a detailed publishing schedule. The post says the author will try to catch up after becoming less busy, but does not name a date or specific upcoming article.

How the Weekly Thread Works

Open Thread 454 is presented as the blog’s weekly visible open thread. Its central purpose is broad reader conversation rather than coverage of a single subject: the invitation allows posts on anything and welcomes random questions. The additional notices range across the community’s online spaces, in-person gatherings, reading resources and interest groups.

The source lists an unofficial subreddit, Discord, bulletin board and meetups around the world as other places associated with the Astral Codex Ten community. It also describes the publication’s access model in general terms: most content is free, with some subscriber-only material. The post does not say that the notices in this particular thread require a subscription.

The thread’s numbered updates cover work by readers and contributors as well as the author’s own publishing pace. Sokolsky is credited for obtaining and translating the Fatima documents, Ana for Portuguese-language work, and Ennals for assembling previous reviews into epub files. The source provides links for the documents and review files, but does not summarize their contents.

Details Readers Must Check

The thread does not give the new time, date or location for the Brigham Young University meetup; it directs readers to the meetup list instead. It also does not detail which documents were obtained from Portugal, when they were gathered, or what they contain. The linked site is the source offered for the English translations.

The post provides no information about the Physicians For AI Safety group’s size, activities beyond its stated interest in speaking with physicians, or the open letter’s wording and signatories. Nor does it set out a timetable for the author’s return to a more regular publishing pace. These points cannot be established from the thread alone.

Check the Linked Updates

Readers planning to attend the BYU meetup can consult the linked college meetup list for its current schedule and venue. Those interested in the Fatima material or older book reviews can visit the respective sites cited in the thread. Physicians interested in AI safety can look up the group’s open letter through its announcement.

Further updates depend on the contributors and author. The post says the author will try to make up for missed writing when they are less busy, but gives no target date. Open Thread 454 itself remains an invitation for readers to join the blog’s discussion spaces and raise their own questions.
