1: The Horizon Fellowship is a full-time US policy fellowship that places experts in AI, biotechnology, and other emerging technologies in federal agencies, congressional offices, and think tanks in Washington, DC for 6-24 months. No prior policy experience required, jobs are fully-funded. Learn more and apply by Aug. 28.

2: Lighthaven (the rationalist community campus in Berkeley) is hosting Inkhaven - a blogging bootcamp aimed at people who want to blog more but struggle with motivation. Selected fellows will live on site for the month of November, and write one blog post per day or else be kicked out. There will be some mentors around including Gwern, Scott Aaronson, and me. I don’t want to over-endorse this - I have no idea whether it will create any kind of lasting motivation or tendency that sticks around after the program, for most people blogging is a low-reward activity, and the cost is pretty steep - but I think it’s a good experiment for Lighthaven to try, and trust potential applicants to make good choices for their own situation. Cost is $2,000 (program only) to $3,500 (program plus housing for one month) to $4,700 (program _ housing + meals). Some financial assistance available. Apply here. And yeah, they should have called it “Writehaven”.
