New comment by senshan in "Processing in Memory: DRAM Is About to Do Math"

Why does not the article say anything on how KV-cache is handled with in-DRAM processing? Is this trivially obvious?

New comment by senshan in "A Kantian Critique of "Sorry" by Justin Bieber"

We can not attribute the moral image of the protagonist to Bieber himself. He is an artist, so he is describing an experience of life, perhaps stemming from the receiving end of a fake apology.

Otherwise, it is a very good and thought-provoking article.

New comment by senshan in "A 25-year-old video patent just expired, ending a legal headache for Linux"

Right, but I thought it matters only if you sell something globally. Linux is distributed for free, so the burden of patent compliance is on the user, isn't it?

Brazil? Why a Brazilian patent is of such a significant interest elsewhere?

Mostly as a subproblem solver for mixed-integer programs, due to ease of warm-start. MIP itself is NP (B&B), so NP*NP=NP

Thanks, very interesting. Basically the authors blast high-power (~92 dBA) ultrasound around 25kHz and hope that microphone non-linearities will overwhelm the audible signal.

This will sure make all the dogs in 20m radius mad. Hence the solution for the stealth recorder -- bring a dog, then complain about the ultrasound jammer (or at least to be aware of a jammer)

From the paper, it looks like the authors did not consider safety of animals, only human hearing safety.

Are you suggesting that holding private credit assets is relatively risk free?

Equity is a risky asset, so equity being wiped out should not be a surprise to anyone, but life insurance and pension funds failures is indeed a public problem.

Typical total bond market fund like BND is ~70% in USG -- pretty solid:

You probably meant to say that practically, high leverage tends to leak into companies of public interest. For example, when high net worth individuals start trimming their private credit holdings, which eventually end up with insurers. That is why the regulators have to watch carefully that it does not happen.

For those who stick to a meaningful asset allocation (e.g. 60/40, 80/20, etc), this does not pose significant problem -- they would not be buying much stock in the last 3 years. Instead, they would be buying mostly fixed-income. Probably mostly in 401k/IRA accounts.

As long as this debt does not make it into life insurance and pension funds, we are fine. The trouble is that private credit is taking control of some life insurance companies and off-loads this debt to these. When these fail, it will become everyone's problem.

> Risks to financial stability may also stem from entities with particularly high exposure to private credit markets, such as insurers influenced by private equity firms and certain groups of pension funds. The assets of private‐equity‐controlled insurers have grown significantly in recent years, with these entities owning significantly more exposure to less‐liquid investments than other insurers

Right. If one lives in an area prone to malaria, has good immune system, will the body tend to carry the antibodies all the time?

No, do not stop the efforts! The story here tells us that risks of being poisoned (once the throne is obtained) are greatly exaggerated.
