fine-tuning a model is very different from training the whole model in terms of resource requirements.

I found gwern's take on Melatonin interesting: https://gwern.net/melatonin

A small excerpt:

> One might object that they do not wish to tamper with their natural sleep, even if melatonin is a normally-secreted hormone.

> Sad to say, I would point out to such readers that they are already profoundly tampering with their natural sleep cycle, and indeed, all of Western civilization is tampering with it; most of my readers do not even sleep multiple times during the day, as ‘Nature intends’ and as humans have usually slept through history, but rather in a single 7–9 hour long block.

> [...]

> Finally, there are multiple lines of research suggesting chronic sleep deprivation is prevalent among young adults (including historical comparisons). It is striking that unemployed adults sleep a full hour longer than the employed , and that when normal adults are placed in settings without artificial light like camping or without any time indicators, they sleep longer than before - exactly as if they were sleep deprived.

Is it really the full pipeline running on Huawei hardware? That is training and inference?

The report only talks about validating the "fine-grained EP scheme" on Huawei hardware.

I don't think memory mirring features available today allow you to race two DRAM accesses and use the result that returns earlier?

If there's anywhere I don't want LLM slop it's probably my database system.

Ah I can't read, thanks :-)

Shouldn't your snippet be using lzcnt? I can't see how this would result in the desired lookup.

for Zen5 rustc creates the following:

  utf8_sequence_length_lookup:
    shl edi, 24
    mov ecx, 274945
    not edi
    lzcnt eax, edi
    shl al, 2
    shrx rax, rcx, rax
    and al, 7
    ret

What's the API here for Google Ads? How does their site report to Google Ads whether that was a good/bad user? Is this done through conversion tracking? If so, why would you track anything but a completed purchase in the first place?

As I understand it they are placing ads on other sites and are paying for visits to their site.

  After we implemented advanced bot traffic detection and filtering, their reported traffic plummeted by 71%. [...]
  But then the sales report came in. Their actual sales went up by 34%.
  Their real conversion rate optimization (CRO) efforts had been working all along, but the results were buried under an avalanche of fake clicks. They were not bad at marketing; they were just spending thousands of dollars advertising to robots programmed never to buy anything. Their marketing ROI went from "terrible" to "excellent" overnight.

I don't understand how detecting bot traffic would directly lead to less ad spend.

Can you just tell e.g. Google Ads that you don't want to pay for certain clicks?

Did they modify their targeting to try to avoid bots?

The author admits to it.

The reply to that comment is also a good explainer of why the post has such a strong LLM smell for many.

The easiest way to parallelize this RNG is to just run it in parallel on multiple states.

I doubt that this is a problem in need of a technical solution. In any case, this system can easily be circumvented by emulating the key presses on that website.

Looking at a few files, there's definitely some generated comments in there. Do you have any method to quantify how much of it is (likely) generated?

Could you elaborate?

Their talk was quite nice, they talk about experiences with other HSMs, their history, what lead them to design their own, the many aspects of their design and then go through potential attacks:

> The article mentions the Cochrane Review which rigorously concluded the opposite.

Do you mean this one?

"Many commentators have claimed that a recently-updated Cochrane Review shows that 'masks don't work', which is an inaccurate and misleading interpretation.

It would be accurate to say that the review examined whether interventions to promote mask wearing help to slow the spread of respiratory viruses, and that the results were inconclusive. Given the limitations in the primary evidence, the review is not able to address the question of whether mask-wearing itself reduces people's risk of contracting or spreading respiratory viruses."

There's some quite complex cryptographic machinery called Direct Anonymous Attestation that would make this possible. I don't know if they plan on using this though.
