I said "likely", not "certainly." Satoshi Nakamoto is the exception that proves the rule; part of his infamy is precisely due to the fact that he has not yet identified, which is extraordinary.

In practice? The odds are pretty likely. Most people have poor opsec, and you can uniquely identify anyone with fewer than 33 bits of data.

That's a fair point; it was mostly the presence of the random crypto that annoyed me :)

She submitted it to ACM Transactions on Mathematical Software. I would personally consider it a cryptography paper, for three reasons: 1. She purports to introduce a novel result that bridges "medium-grade" performance character

Regardless of her attitude on academic accessibility, it is inappropriate for a paper introducing a novel primitive with proposed security considerations to spend the time explaining why determinism is a concern in functions dealing with ra

> On the other hand, maybe spending more than a line explaining what the birthday paradox is should be cut out and put in a backgrounder paper or appendix so that the paper can focus on the actual novel ideas. That was my annoyance wit

The peer review process absolutely produces false negatives, but that doesn't really change the fact that this paper doesn't need to be nearly 60 pages, doesn't sufficiently analyze one of its central premises (6.2.2 Security

I disagree, I think the peer review functioned exactly as it was supposed to. Her paper doesn't pass the sniff test for me whatsoever when it comes to security analysis. She spent close to no time analyzing the primitives she introduce

I have a few comments: 1. The paper itself[1] is extremely readable by the standards of most cryptography research. On one hand, this is great because I was able to follow the whole thing in essentially one pass. On the other hand, the pa

I agree. I'm not a Snapchat user and generally dislike the app. But I have the Spectacles and recently took them to a trip to Six Flags to record point of view videos on a bunch of the rides. It was really fun, and I even installed the

$10,000 - $12,000 per week is normal for an application security assessment. Go ahead and double that for a specialization like protocol cryptanalysis. Ballpark $40,000; maybe more because there were three consultants, not two. I wouldn&#x2

That volatility is perfect for a mean reversion strategy.

Right but that's nearly tautological...I meant specific applications that can tolerate the massive performance sacrifice.

What are those applications?

The thing is that no one is really motivated to make a complete tutorial on finding strategies because it's economically irrational. You're either giving away specific sources of alpha or you're empowering potential competito

You can actually have scientists find signals in data they have no domain experience in. In a typical hedge fund the quantitative researchers will be a different group from the quantitative developers and traders. There are fuzzy lines betw

It's hard for me to follow exactly what you're getting at here, but (to make an analogy to cryptography) it seems like you're saying it's hard to find a signal because we only have the apparently random output of a funct

Well said. Where most funds have the same problem 'chollida1 describes here[1], Rentec (and other similar firms) moved past that by establishing the right culture and investing in the right technology from the outset. They need smart p

Rentec uses machine learning, but more importantly the firm curates massive amounts of high-signal data. The most significant part of their work lies in process automation and the rapid testing of hypotheses, which empowers the optimal use

In what way is Chrome "kinda borderline"? If you mean borderline in terms of success, there are only four or five meaningfully used web browsers. Of those, Chrome has the largest desktop and mobile marketshare, respectively.[1] If
