Great article! I feel that the article is a bit vague about the applications of homomorphic encryption, so I'll add some examples. For instance, suppose that your mail server encrypts your mails, and only you can decrypt them. If you w

What? Bayes' theorem does not require anything about the events, even more so it is useful when the events are not independent. If events are independent, Bayes' theorem has no usefulness. https://en.wikipedia.org/

There are problems that I find even more counterintuitive than Monty Hall, such as the sister's paradox. Your neighbours has two children, one of which is a girl. What is the probability of the other child to be a girl? A.

In France, we had a similar case, a computer guy with the pseudonym Bluetouff[0]. He downloaded loads of national agencies confidential documents, because they were available on Google. However, he was sentenced (3,000€ fine), because when

"Valid" configurations do not exist, there are only optimal/suboptimal and saturated/unsaturated ones. The classic FPR makes no assumptions about this (indeed optimality is derived from FPR minimum), and as such should a

Strange coincidence, just this morning I was reading a paper [0] from 2008 about Bloom filters. Specifically, their false positive rate is higher than what is usually advertised - even on Wikipedia. Edit: also as is written in the document,

The idea is that two elements x and y despite having the same fingerprint, will be stored into two different buckets. So you can have several time the same fingerprint in a Cuckoo filter, which you can't in a Bloom Filter. When you wan

I don't think it's the case yet. GDPR will enforce the right to be forgotten and as such truly delete data about you, but other than that, I don't think there are other regulations forcing you to delete data.

I have an opposite story. Once upon a time in the French countryside, there was an old pastry chef who was well known for her unique creation (of which I forgot the name), that, even 40 years later, my father still praises. The recipe was o

I don't find it easy personally, my most upvoted comment has 14 points, most are under 4 points. But then, I don't comment often and I don't care about being able to downvote, so I think I'll survive.

- According to wikipedia, the launch mass of the Falcon Heavy is about 26 tons for a geostationnary launch, which is quite a lot and definitely enough for ISS like launches. I guess either the launch mass is way lower for leaving earth'

All right, but then why are most open-access papers under $3000? If an editor can survive with these fees even when the paper will be publicly available, how can Nature need $30,000 for a paper people will pay to read?

Well, yes, but it's the same thing, really. It's what my last paragraph above is about. E=mc² is not about nuclear reactions, it's about every reaction. A chemical reaction of combustion transforms some fuel molecules into ne

Well, in case of a rocket, there are two phenomenon resulting into thrust. The first one is the action-reaction principle: fuel goes in one direction, rocket goes in the opposite one. The second one is indeed the E=mc^2 equation: as the fue

The conversion you are talking about is true only if you annihilate your fuel (which creates photons), and then you convert photons into speed in some way with 100% efficiency. But really this never happens, rockets work by ejecting mass at

As I explained in an other article here on HN, another meaning (and the most important one imo) is the one Einstein actually wrote about: the inertia of a particle depends on its energy. The thing is, you don't read E = mc² but rather

What bothers me with this blockchain is, who will actually run the nodes? If only the merchants do so, then they can also counterfeit everything just as they want. In the end you rely as much on your trust to the merchant than with the clas
