Tangential: About 8 years ago ex-Apple chip engineers left to design server-grade chips, this was Nuvia, and they got sued by Apple to the point that they had to get acquired by Qualcomm.

Isn’t the case with Postgres too if one doesn’t change the default primary key index for which is B+ Trees? At least Postgres supports a hash index IIRC, but I’m not sure if most developers set it to that when they use UUIDs as primary keys.

Not really I think, they built a simulation engine for autonomous driving, for which tons of such exist out there including ones from Nvidia and also at least 1 open-source one. Using world models is different.

For these single-website to explain things, I really like that HN's 1-click link to view past submissions shows the past posts (I have seen this useful website come up in the past!):

Interesting point:

> The research suggests that increased NDRG1 expression emerges through what the scientists call a "cellular survivorship bias"—stem cells that don't accumulate enough NDRG1 die off over time, leaving behind a population of slower but more resilient cells.

This exactly.

If this works well, then I could finally see that AI wearable pins could be socially feasible. IMO speaking aloud in public to AI doesn't seem like something which will work but it is also what OpenAI is apparently investing a lot into with their hardware ambition with Jony Ive [0].

> Tesla’s far more popular models are the 3 and Y, which accounted for 97% of the company’s 1.59 million deliveries last year.

TIL that Model S hasn't been as popular. But hopefully when the 2nd gen Roadster finally gets released that it will fill in the slight gap left by Model S's discontinuation.

Even India recently has repatriated some of its foreign gold reserves (from Bank of England (and possibly other places)):

Also, not on the list: iCloud having a hard limit of 50,000 total calendar events and silently not syncing beyond it (and similar to the first iCloud Photos issue mentioned on the website: no indication of syncing state to know what's going on). For perspective, as someone using the Apple ecosystem for 10+ years now, that this comes to 13 events a day for 10 years.

The OG quote by him is about rice. Nevertheless, very funny!

I thought this article would have to do with the transfer of ICANN's power from the US government to a general non-profit thing in 2016.

Really interesting research. Rest in peace. An aside: The cause of death was a stroke: https://nutrition.utexas.edu/about-us/memoriam

The key point, which at least the top comment here is missing and others may overlook of the article, is that the article states that the USD currency reserve is still the same but that the other currencies being present in the mix have increased and thus the USD proportion has decreased (not that the absolute amount of USD being held decreased). However, the implication is still the same and that is that the rest of the world's central banks are holding relatively less USD.

> Autonomous vehicles might see their surroundings with unprecedented clarity.

This is a pretty good point, which gets me to wonder whether the developers of autonomous vehicles use variable focus adjustments as a part of their ML stack? Or simply set the focal point to infinity.

From the "about" it seems that the data is from atmospheric models based on flight paths. However, it would be cool if the data could be inferred from satellite sensing.

Can someone please clarify: For the phone number to reach the enclave for use during search via XOR, won't it need to come in as regular RAM via the backend's API call?

Also, I wish there was a setting to disable ChatGPT in its system prompt to have access to my name and location. There was a study on an LLM(s) (not image gen) a couple of years ago (I can't find the study now) which showed that an unfiltered OSS version had racist views towards certain diasporas.
