Any chance you could pin the 'Updates Thread' too?

Of course, but there reaches a level of sun exposure at which the marginal increased harm becomes negligible compared to other things that damage your skin (see this meta-analysis - photo-aging is just one component among many), and below that level you're probably actually getting suboptimal levels of UV exposure for skin health (see this article for benefits of UV - from Norway, aptly). 

I'd love to see someone try to measure and compare the specific trade-offs, but I strongly suspect that people at northern latitudes should just trust common sense - only wear sunscreen in summer months, and when you're actually exposed to the sun for extended periods. 

Below are the new tacit knowledge videos added to the post since mid-April.

• Paul Meehl, Philosophical Psychology 1989 course lectures, "deep introduction to 20c philosophy of science, using psychology rather than physics as the model science -- because it's harder!" (via @Jonathan Stray [LW · GW])
  • "Meehl was a philosopher of science, a statistician, and a lifelong clinical psychologist. He wrote a book showing that statistical prediction usually beats clinical judgement in 1954, and a paper on the replication crisis in psychology in 1978. He personally knew people like Popper, Kuhn, Lakatos, Feyerabend, etc. and brings their insights to life in these course lectures."
  • Me: I was hesitant to add a lecture series to this list at first. I changed my mind after listening to the first video, where Meehl provides interesting details (gossip, almost) about the life of an academic and the various personalities of his successful academic peers.

  • “Kenneth Folk is an instructor of meditation who has received worldwide acknowledgement for his innovative approach to secular Buddhist meditation.

A challenge posed on Twitter recently has interesting similarities with this effort (although it focused on in-context learning rather than fine-tuning):

A::B Prompting Challenge: $10k to prove me wrong! 

# CHALLENGE Develop an AI prompt that solves random 12-token instances of the A::B problem (defined in the quoted tweet), with 90%+ success rate. 

# RULES 1. The AI will be given a random instance, inside a <problem/> tag. 2. The AI must end its answer with the correct <solution/>. 3. The AI can use up to 32K tokens to work on the problem. 4. You can choose any public model. 5. Any prompting technique is allowed. 6. Keep it fun! No toxicity, spam or harassment.

Details of what the problem is in this screenshot.

Lots of people seem to have worked on it, & the price was ultimately claimed within 24 hours.

Updates Thread. Below are ~monthly updates with lists of new tacit knowledge videos.

Survival vs self-expression: Survival values prioritize security over liberty. Those with survival values tend to be more homophobic, uninterested in political action, distrustful of outsiders, and less happy. As people transition from industrial to knowledge societies, their sense of agency increases and they move towards self-expression values. 

To me, the empiric status of that claim feels quite unclear. Is that your personal opinion? Is it a general pattern for which there's existing data?
 

You are a scholar and a gentleman.

Here is an archived version of the page :

Archived website

Way back in the halcyon days of 2005, a company called Cenqua had an April Fools' Day announcement for a product called Commentator: an AI tool which would comment your code (with, um, adjustable settings for usefulness). I'm wondering if (1) anybody can find an archived version of the page (the original seems to be gone), and (2) if there's now a clear market leader for that particular product niche, but for real.
