My best guess: the article is 726 words; That's pretty short by HN's standards.

There are just overloaded notations from two different contexts. sin² can mean either: * x → sin(x)² (in multiplicative group) * x → sin(sin(x))² (in composition group) Similarly, sin⁻¹ can mean either: * x → 1 / sin(x) (in multiplicat

This is effectively wishful thinking. If a bug causes an unexpected undefined value, it will lead your code to an undefined behavior. It might work well 999 times and wipe everything on the 1000th execution. Thankfully, Javascript is mostly

I mostly agree, but I'd argue that epicycles actually made useful and testable predictions, although we found a simpler description later on. The article underlines a lack of refutable theories. Thus, I think [1] is a better analogy. [

I think the point is that this kind of article tends to present it as uniformly better, rather than contrasting the good and the bad.

I feel this is an instance of Flanderization [1]. There are definitely some differences between France and the US, but they get blown out of proportion. And this is not specific to France, other articles take northern countries as the golde

A signature is not a hash. As long as you know the right public key (which only needs to be transferred once), you can verify the legitimacy of the signature regardless of how it was transmitted.

I agree that password managers are great. They let you use completely different passwords for each service, efficiently mitigating any compromise. Also, they tend to encourage you to use actually random passwords (using a generator). Howeve

However, such an approach corresponds to a few dozens bits of entropy at best (some for the approach, some for the length of text used, and a few for the numeral depending on whence it comes). As stated by zamalek, the trick to not memorizi

The worst bias is letting the users choose their passwords. They should use a generator such as [1]. The reason is that the "entropy" is not a characteristic of a password but of the way it is generated. Computers are much better

From my experience, a self-hosted web aggregator is the most convenient option. I initially wrote my own (very clunky) in PHP when I realized Thunderbird would not do. I am currently using FreshRSS [1]. MiniFlux [2] and TinyTinyRSS [3] are

Very good point! Since some websites still require PIN codes (passwords made of digits), you would have to restrict yourself to something like 8 digit long password, which is not very secure, even with a slow hash (scrypt iteration).

My main gripe is with: > Nothing is stored so there’s nothing to steal. Nothing is stored, but it's public knowledge. In a traditional password store, there are two levels of security: limited access to the encrypted passwords, and

Of course, some have. See Stuxnet (actually somewhat serious). The point is that this intersection is fairly small and only a fraction of compromised systems will actually get things messed up.
