There are about 30 million seconds in a year. If they made $100 over the last hundred milliseconds, then that’s $30B annualized. (That said, their numbers are much realer than that.)

The original Mac system software was written in Pascal and most Mac toolbox calls took Pascal-style (prefixed by length) rather than C-style (terminated with null character) strings. But you could write application code in either language k

I'm like you. I loved Apple IIs at schools and libraries as a young child, fell in love with my Mac IIsi at home at the age of 7. Later, at 13, I had a Macintosh-evangelizing web site and mailing list that Guy Kawasaki (Apple's le

In microgpt, there's no alignment. It's all pretraining (learning to predict the next token). But for production systems, models go through post-training, often with some sort of reinforcement learning which modifies the model so

Yes, the actual LLM returns a probability distribution, which gets sampled to produce output tokens. [Edit: but to be clear, for a pretrained model this probability means "what's my estimate of the conditional probability of this

That's 4–6 months in the 18 months the trials lasted for, i.e. about a 30% slowdown of progression. The open-label extensions suggest this relative slowdown seems to continue at least to the 4-year mark (at which point it would have bo

It’s one of the best blood tests. There are also PET scans, lumbar punctures (spinal taps), and postmortem analyses of brain tissue.

I don’t think we should preemptively surrender our free speech to the authoritarians.

Even the counting numbers arose historically as a tool, right? Even negative numbers and zero were objected to until a few hundred years ago, no?

A mistake in this critique is it assumes an exponential: a constant proportional rate of growth. It is true that, in some sense, an exponential always seems to be accelerating while infinity always remains equally far away. But this is a bi

One note: the standard deviation of the remaining effects would be sqrt(1/2) as large, not 1/2 as large. So more like 8.5-10.5 years.

In some redacted documents, there is even an alphabetical word index at the end with a list of pages on which the words appear. The redacted words are also redacted in the word index, but the alphabetically preceding and succeeding words ar

The article seems to suggest the false positive rate is only 38%: The trial followed 25,000 adults from the US and Canada over a year, with nearly one in 100 getting a positive result. For 62% of these cases, cancer was later confirmed. (

Unfortunately, I don't think the mechanism is quite restricted enough. TFA says that repairing the BBB helps amyloid plaque clearance. Would the author of your blog post claim that as a win, or admit that the plaques are downstream of

To add to this, a moderate amount of turbulence (a type of chaotic fluid flow) in engines and wing surfaces is sometimes deliberately engineered to improve combustion efficiency and lift, and also chaotic flow can induce better mixing in he

Thank you for your kind words. I hadn’t seen that research, thanks for passing it along. It seems like an interesting approach to improve slow wave sleep, which is known to help with amyloid clearance.

while Alzheimers drugs may be more effective earlier in the disease course, none of them are "effective" in the sense of meaningfully staving the disease off; the upside to early detection is not very strong. One correction here

Circling back to the original topic: at the end of the day, whether it makes sense to expect more brain-like behavior out of transformers than "mere" token prediction does not depend much on what the transformer's original cr
