We need more people reading more books! Such an important skill and has done so much for me.
There’s nothing better than a good book, a change in perspective, beliefs or the generation of new ideas.

Genuinely enjoying how much layered wrongness is here.
A kind of beautiful tiered wedding cake of misconceptions.
Just BATHE in the warm rolling folds of daftness.

And then there was Bryan Johnson, a Silicon Valley multimillionaire known for his extreme anti-ageing ‘biohacks’, like receiving plasma from his teenage son.
Johnson, on a quest to live forever, wants “competing for the best biomarkers of anybody in the world” to be something of a new sport.

First up: Alexander Gibson @alexdgibson.bsky.social: Poor Data Provenance in Published Clinical Prediction Model Research.
I was seriously concerned about some of the Kaggle Datasets - those on stroke and diabetes raised concerns about data being fake.

Ok, time for a short thread about this paper.
My sense over the past six months or so is that chain-of-thought prompting as used in e.g. ChatGPT o.3 improves substantially upon previous systems such as ChatGPT 4.o, at least for certain tasks.
But how revolutionary is it?

If I have time I'll put together a more detailed thread tomorrow, but for now, I think this new paper about limitations of Chain-of-Thought models could be quite important. Worth a look if you're interested in these sorts of things.

Reading over my brother’s undergraduate assignment.
Criteria has a section: “Is there an appropriate amount of detail in this section so that you could replicate this study?”
I don’t remember learning about replication in my undergrad! Nice to see it getting some air time.
