The algorithm is very nice. But I think you should think about what it means to divide one integer by another. The quotient of that operation is an integer. The remainder is an int…

Finding divisors is often hard when your number is large. It turns out the condition that a number n can be expressed as a multiple of two other numbers is equivalent to there bein…

What are the arguments against RSA OAEP?

Is he though? He publishes frequently in a bunch of journals that I've never heard of but an actual cryptography expert would know that it is the asymptotic behaviour of an algorit…

This is a recent development. Apple only started to care about iOS security around 2012 for example.

It looks like you have an incomplete understanding of the meaning of 'mislead'.

Quantum computing is an area where the hype is out of proportion to the certainty about time until its feasible. With self driving cars there are arguments about the number of deca…

"Define a function h such that h(f(x), f(y)) is true iff x = y" If an attacker can compute such a function then any cryptosystem would be broken because of the attack you give. The…

Good mathematical work is rarely an all or nothing proposition. Many independent ideas are required and when the mathematician is very good it is rare that there will be many mista…

Assuming that users who installed the app already understood the need to provide their location data. This allowed them to axe out the long-winded welcome flow and make the permiss…

My point: If you find a group of us to be deers because we allow ourselves to be distracted from the work we are required to do by the criticisms we have of others then you are mad…

> Not really, Kahneman is talking about doing better or worse than expected, not about your best or worst performance. At a given point in time there are two quantities we need to …

First, the demonstration Kahneman arranged is simply a demonstration of regression to the mean and is not evidence of the validity of his hypothesis. Is the hypothesis itself wrong…

I agree there is almost no content in this post. Reasonable cases could be made both for and against the point I think.

Where did you get nobility from. This isn't the author's point at all. Obviously knowledge about different areas of knowledge can be of more practical benefit at different times. T…
