The hardest CS undergraduate course offered is probably 189: Introduction to Machine Learning. Nonetheless that class has a B+ average; so I wouldn’t say difficulty of class correlates with a low grade average. There are others like 170 and

I think it’s because data science has a more immediate, broader applicability than computer science. Not everybody needs to know how to program a full application; but they should be able to load in a dataset and statistically analyze it. L

After rereading this article [1], I’d have to agree the Erdos model is ill-fitting — but still disappointed no model was mentioned. [1] https://www.quantamagazine.org/scant-evidence-of-power-laws-...

I'm surprised the Erdős–Rényi model [1] isn't mentioned in this article along with Metcalfe's Law and Zipf’s Law. There's a nice phenomenon with random graphs: if the probability of two users being connected > log n &

In the SEC briefing, it is noted that there were two teams deployed: Project Sierra and Project Sparta. Only Sierra had knowledge that Equifax itself was breached and thus a blackout period was instituted. But not for Sparta where the CIO w

It’s not as black and white as it seems: the CIO was not directly told that Equifax itself had suffered a breach, simply that one of their clients had been. [1] https://www.bloomberg.com/view/articles/2018-03-15&#x

Nakamoto consensus isn't the only protocol that exists; there's also things like Raft and Paxos with different tradeoffs.

To people who use Tinder or Bumble, would you prefer matching yourself or have an algorithm do the matching for you?

Can I ask you a quick question: do you think Merkle trees are a good model for key revocation? I'm currently working cryptographic file system for a class, and trying to speed up the sharing and de-sharing of files via symmetric keys.

Damn, I just learned about linear programming in a class and about MCMCs in another; this is why I love reading HN: there's so much more CS to learn!

I recently learned in my security class that certificates are the way by which domains are publicly identified. But I don’t understand why there hasn’t been any alternatives besides trusting these companies to issue certificates...

Kind of reminds me of PageRank in someway; the number of "backedges" is not guaranteed to equal number of "forwardedges", hence the difference in number of paths.

A creator of IOTA said that broken collision-resistance is actually a feature, allowing them to use their centralized node to attack "scammers". The whole narrative from the start has been decentralized cryptocurrencies; but IOTA

I only got to page 30 before moving on, but this line is telling: > In this case you are right, second-preimage resistance is an anti-feature, collision resistance threat is nullified by Coordinator while allows us to easily attack scam-

In simpler terms, given H(x), it is impossible to find x’ such that H(x’) == H(x) in polynomial time.

How would using the hash of a hash strengthen the property of second preimage resistance? The space of all possible hashes is still 2^256. The only impact I see is that the cost of computing a hash is doubled.

Ironic that the plan to keep mining decentralized requires centralization itself. Same thing happened with SIA earlier when another company beat SIA's founders to the market with an ASIC.

"How would you decide when to use an FPGA and when to create an ASIC? That depends. FPGAs waste a large amount of silicon compared with an ASIC, so the cost floor, which depends in large part of the surface area of silicon required for

Don't focus on Bitcoin; focus on the general idea of cryptocurrencies: international, fast, secure, decentralized. That idea is magnitudes of order way more difficult to implement than a banking platform built on top of preexisting inf
