Claude Opus 4.7, on the web at least, really likes the word epistemics.

The pulsing macbook leds were horrible. I was in college then, living in dorms or other shared housing where my laptop was always in my bedroom overnight. I got in the habit of putting a dark shirt over it.

Here's an interesting thought experiment. Assume the same feature was implemented, but instead of the message saying "Claude has ended the chat," it says, "You can no longer reply to this chat due to our content policy," or something like that. And remove the references to model welfare and all that.

Is there a difference? The effect is exactly the same. It seems like this is just an "in character" way to prevent the chat from continuing due to issues with the content.

This is awesome. I had the same feeling I had when I first played GeoGuessr. It's one of the first times I've seen what is obviously AI-generated video used in a super compelling way. I want to keep playing.

A few super nitpicky comments:

- I dropped my pin for "Seward's Folly" on Alaska. The videos were clear enough that I knew that's what it was, which made me excited. But then it said it happened in Washington, DC.

- It might be sample bias, but I've only gotten events after year 0 (and technically, it went from 1 BCE/BC to 1 CE/AD.

I'd love to play with this my seven year old, but some of the images are too violent. A "PG mode" would be awesome.

I gave up on gpg when I couldn't get my key signed at defcon multiple years in a row. If there's not interest in it at defcon, I don't know where else to go.

It’s called Bayesian Search Theory, and is even more interesting when you consider that not finding it at a given location gives you information about where it might or might not be.

The all matching socks strategy breaks down over time. Eventually you need to buy more socks, and the new ones aren't as worn as the old ones, so you end up having to match them anyway. My solution to this is to buy a large batch of identical socks. Then when you need new ones, buy another large batch that are slightly different - e.g. grey hiking socks instead of black, or wool hiking socks that have a slightly different pattern but are still the same style. This reduces the matching problem from matching all pairs to matching into a couple different sets, which is much easier.

I've thought too much about this.

Given that it's suspended again - if I create an account that tweets where Elon's jet was yesterday, would that be ok?

Well up to 25 dbHL is considered "normal" hearing for an adult. Without a hearing test I wouldn't have known I had any hearing loss.

I have tinnitus and hearings aids help a lot. I only have mild hearing loss (35db at high frequencies in my worse ear), but it matches the frequency of my tinnitus.

It’s possible to develop relationships remotely. It takes effort, but doing so in person also takes effort.

This sounds crazy, but try hearing aids. That worked for me. Initially I used the white noise masking feature of them, but switched to using just amplification. I stop noticing my tinnitus a few minutes after I put them in, and it starts again a few minutes after I take them out.
