๐Ÿ’ฏ my model for who is looking for market/ legal remedies vs federal/ social remedies is very unreliable these days

Thinking: โ€œtoo many model releases/ announcements today, ugh.โ€

*looks at job title*

Damn.

Told the bf that liking โ€œSoda Popโ€ more than โ€œGoldenโ€ or โ€œWhat it Sounds Likeโ€ is a relationship crime.

15-20 years ago, Iโ€™m imagining trying to convince record labels that the top 10 would be dominated by the kpop ost, of an animated show, on a streaming service.

Oh, for sure!

If I felt that the vibes were distributed between distanced critique and participatory good-faith explorations, then there wouldnโ€™t be much to say โ€” but, to my surprise, more folks on bsky have been popping up and saying that is definitively not the env weโ€™re in.

That any technology might lower the barriers of entry to exploring different disciplines?

Sounds suspiciously like liberal arts and sciences to me!

A lot of times folks on the left adopt the logic they critique, happily clapping along when there are signs that LLMs arenโ€™t immediately providing hyped amounts of utility.

Thereโ€™s a lot to say about that. But Iโ€™m already excited by what Iโ€™m seeing. Ie. Artsy folks vibe coding indie games.

I am delighted to share our new #PNAS paper, with @grvkamath.bsky.social @msonderegger.bsky.social and @sivareddyg.bsky.social, on whether age matters for the adoption of new meanings. That is, as words change meaning, does the rate of adoption vary across generations? www.pnas.org/doi/epdf/10....

Subliminal Learning: Language Models Transmit Behavioral Traits via Hidden Signals in Data

alignment.anthropic.com/2025/sublimi...

Oh interesting, student models/ fine tunes might pick up statistical signatures of a parent modelโ€™s internal state.

โ€ฆBut can Anthropic convince me that this wasnโ€™t written by owls? I think not.

Oh yeah, all the new agent based language + the ml language ๐Ÿ˜‚

Cog Sci students who specialize in ml are extremely well positioned โ€” everyone else thoโ€ฆ ๐Ÿ˜‚

And Iโ€™d argue that controlling the latter three components is a losing battle.

So I feel like the only place to get more traction is to make sure college students take certain courses.

๐Ÿ’ฏ

The combination of educational prerequisites + reactionary social media accounts + large vocab of tired sci fi tropes + fast rate of change?

It becomes very hard to have a cogent conversation about the topic.

Lolol, โ€œhow long of a reasoning inference run = agency?โ€

This came up because someone took back their surprise about Claude solving a math problem, being like โ€œactually, I think it could do this already.โ€

And, actually, a year ago, no it really could not have.

The pace of llm developments is so fast that it makes it easy for humans to hallucinate that nothing is changing/ improving.

Ie. Folks will sometimes say โ€œwell LLMs were always going to be good at math and codeโ€ โ€” when like a year ago LLMs doing basic arithmetic was the topic of conversation.

But itโ€™s definitely possible I should just get used to navigating multiple code agents at once โ€” I might just have some unfamiliarity based reservations! ๐Ÿ˜‚

29.07.2025 17:23 โ€” ๐Ÿ‘ 0    ๐Ÿ” 0    ๐Ÿ’ฌ 0    ๐Ÿ“Œ 0

Thatโ€™s my impression, and I worry about collisions between multiple agents handling my shorter term queries (maybe unfounded).

Maybe I want something like a short term agent that handles my โ€œimplement thisโ€ queries โ€” and a longer term agent that only reorgs stuff Iโ€™ve written.

29.07.2025 17:22 โ€” ๐Ÿ‘ 1    ๐Ÿ” 0    ๐Ÿ’ฌ 2    ๐Ÿ“Œ 0

One part of the llm-coding experience that Iโ€™m not a huge fan of is the downtime between queries.

Would be cool if there was a tool that was like โ€œother design decisions/logic that youโ€™ll need to think about.โ€

Kind of like anticipating stuff I might need to consider, design patterns, etc.

Actually, now that I think about it, it fits into a nice history of โ€œthe gothic and aesthetic critiques of real estateโ€ โ€” capped off with Paranormal Activity and the McMansion.

29.07.2025 16:31 โ€” ๐Ÿ‘ 3    ๐Ÿ” 1    ๐Ÿ’ฌ 0    ๐Ÿ“Œ 0

I think that was my experience.

I only happened to see a link to The House on the Moor, thinking that the title was hilariously on the nose, and I was happily given exactly what was advertised โ€” plus some occasional lines of interior decor critique ๐Ÿ˜‚

I felt like I learned about George MacDonald and George Gissing pretty late? I guess this is defining underrated as under-taught, less an aesthetic judgement about their writing itself.

100% โ€” alas, we donโ€™t always say these things in a progressive/ city-planning sort of way, as we sometimes say it in more of an eff all motorists kind of way ๐Ÿ˜‚

My partner and I are both avid bikers/pedestrians who avoid narrow death โ€” not infrequently.

And I think it has caused us to mutter uncharacteristic things like:

โ€œCar owners are fundamentally broken.โ€
โ€œWhen Iโ€™m mayor, I say we ban all cars.โ€
