> If not, it seems like we should operate on our best hypothesis with evidence for it, not speculate about unknown unknowns. Nope! We shouldn't. Speculation is precisely what we sh…

I wish yours wasn't the only comment talking about this. It saddens me to see articles like this, where causation is imposed on correlation. Everyone "knows" correlation doesn't im…

I can see a few compelling arguments for it, but personally I'd be very wary of concluding causation from this relationship. The two things are very complicated and have many confo…

That raises profound and fascinating philosophical questions about the nature of knowledge and happiness. I wonder how many of those people would choose to forego the knowledge of …

Apple actually does. Like I said, that icon is in the article, right after the paragraph I quoted. Look at the images the author included. The author is making the point that this …

Apple has icons for SSDs. They are shown in the article right after this: > So what should Apple do? Customized icons for different types of drives would be a good start. Time Mach…

Usually because the strategies which have genuine alpha and consistently outperform are capacity constrained, and so cannot be scaled to handle both. Of course, at RenTech in parti…

Usually top ~20 schools with a bachelors in math or CS. Sometimes Masters or PhD, but those end up working directly in research. The new grads I know aren't actually quants.

They work in what's usually termed the "front office." Quant, sure, but also research development (read: trading algorithm implementation).

That's not really how it works for software engineers/quants. But in general, yes.

Some funds share bonuses across the entire firm, while others operate as internally competing pods/teams. I know people at Jump Trading doing spectacularly well because they're on …

You're talking about banking. I think the context of the original question is actually the buy side, because that's the comment you're replying to. I have not seen any of the typic…

Important note: the person you're responding to is talking about the buy side. It's not uncommon to find a work life balance resembling tech in the buy side. For example, it's a po…

Yeah that definitely seems off. I worked at a tech company where approximately half our employees were customer support, and each was paid closer to $30/hour. I don't see how we co…

This is a great comment, but I just want to point out: > Bcrypt is not a KDF and not a hash function This is true, but it's also a good example of what I was saying in my other com…

I don't know of a good source beyond textbooks or papers which focus precisely on the low level crypto details you (rightly) want to avoid. There just isn't much of a need for that…

That's a good point; I was just giving you a handy chart with an explicitly called out platform :)

Unfortunately, not all password hashing algorithms are key derivation functions. That's just a common design and closely related.

I'm not sure I'm following you. I'm also not arguing for or against the results here. I'm just giving you the background to understand the author's point; it's not something they j…

There is a comparison of Blake3 to various hash functions (including SHA-2 and SHA-3 families) on AWS c5.metal; see the chart here: https://github.com/BLAKE3-team/BLAKE3

That's because the author is using constructive mathematics (i.e. computable analysis instead of standard real analysis). It is true that all computable functions are continuous. L…

Which post-quantum cryptosystems are more efficient than RSA?

I successfully started a 501(c)(3) private foundation for precisely the charitable purpose of "supporting (scientific) open source software" in 2017. The IRS granted it with no que…

What's the point being driven at here? Is it minimizing the deaths of Australian wildlife, or is it making a quip about the sheer scale of cat hunting activity? If it's the former,…

Please tell me a few of these objective reasons why someone who puts "country music" on their resume as an interest isn't sending a good signal. As a resume screener you should cal…
