250 K at ambient pressure is still revolutionary, as it can be reached by dry ice. The highest critical temperature at ambient pressure had been something like 150 K: still above boiling point of liquid nitrogen, and won Nobel Prize in Phys

Some background: there were two Chinese teams publicly pursuing LK-99-derived room temperature superconductor, which I arbitrarily named "north China team" and "south China team". North China team was headed by Hongyang

This is a derivative, with slightly different chemical formula (namely, this includes sulfur, while LK-99 didn't).

Yes it will, but experience from South Korea says it won't be cheap enough to matter. See https://news.ycombinator.com/item?id=30380897 .

Eh, this is an independent confirmation (from Chinese team, of Korean team).

As I understand, neither EmDrive nor E-Cat could be reproduced by any third party. This paper is a third party reproduction, so it seems pretty different.

Why do you think this?

by sanxiyn 3y ago
That's Jicheng Liu, the first author of this paper, and a different person.

At least she immediately commented on this paper. https://twitter.com/iris_IGB/status/1736947651126415426

Since the explainer is pretty long (but it is much more fun to read than the paper, because it is written for the lay people and the paper for experts), here is a sample. It is a description of discovery of memory effect referred to in the

What modifications? About the only thing they write about synthesis in this paper is "We follow the procedure of Lee et al. to synthesize our CSLA samples, with 1:1 mole ratio of Pb2(SO4)O and Cu3P", which doesn't show any mo

A corresponding author (Yao Yao) wrote an explainer of the paper, which you should read together. The paper itself is pretty cryptic. https://www.zhihu.com/question/635259000/answer/3330698364

I don't think any conspiracy theory is needed. Since old board needs to agree to new board, some compromise was made.

This requires retraining from scratch, so no, you can't use Llama 2 pretrained weight. As far as I can tell you can take Llama 2 modelling code, training infrastructure, training data and apply proposed modification (they provide PyTor

Why? As an economist, he perfectly understands what is a public good, why there is a market failure to underproduce a public good under free market, and role of nonprofit in public good production.

by sanxiyn 3y ago
IRS requires a nonprofit to have a minimum of three board members for such reasons.

Old board needs to agree to new board, so I think some compromise is inevitable.

Maybe Sam wanted to redirect Ilya's GPUs to ChatGPT after DevDay surge. 20% of OpenAI's GPUs are allocated to Ilya's team.

by sanxiyn 3y ago
As far as I can tell, this is correct.

by sanxiyn 3y ago
I am not sure why. As far as I can tell, the board doesn't need to answer to anyone.

Emmett Shear is probably the person most friendly to OpenAI board's AI safety agenda among possible candidates. Source: have a look at his Twitter.

My understanding is that if you are renting your data center space right now, power still is the limiting factor and you will need to leave some rack space empty to be able to run GPUs. On the other hand, if you are building your own data c
