comment Difference of two exponential RVs
insularity of [my] analysis", perhaps just say that, instead of pretending that you actually care about what I have to say. It would save us both a lot of time.

comment Difference of two exponential RVs
Yes - we did not reach the said conclusions, you did, passing your own judgement off like we'd actually discussed it, agreed, and come to some mutual agreement is rude. You were pretty adamant that you didn't follow what I was saying, so I do not see how that could be the case, unless you were only feigning ignorance, which would be both rude and annoying. Yes, there are plenty of mathematicians who like the notion that mathematical truth is detached from reality, not saying your one of them, but they most definitely exist. Now, if you do indeed wish to "[draw] my attention to the ...

comment Difference of two exponential RVs
Not really, that would most likely be choosing your description so that the maths is easy, not for the type of simplicity described by the pragmatic maxim. // we is the incorrect personal pronoun here (and typically rude) - the advantage is realism, whilst I understand that doesn't matter for many mathematicians, it does to others. Just because I think using $1_x$ is stupid, does not mean that I do not know why others choose to use it, in fact I use it myself sometimes, but I still consider it to be a hack. Likewise, writing a computer algebra system that way would end in disaster.

comment What does δA mean in differentiation?
That's by Leonard Susskind right, from his online lectures I thought he was quite a good teacher - are you using those too?

comment Generalised logaritmic function
Cool, seems the problem is much deeper than I thought when I wrote the question.

comment “universe” in set theory and category theory
Just thought I should add that the "universe of discourse" is used more widely than mathematics, usually referring to a group of people sharing similar assumptions discussing the similar things (though not usually a set)

@Piostruk do let me know how you get on. I would be interested the approach you end up taking.

comment Variance of random variable
@Did Nope, I would not be so bold. There are plenty of answers that expect you would describe as being without proofs here, the custom is not only to write proofs. I'd defend your right to think and say it should be otherwise, but personally I like them, as do others.

comment Variance of random variable
@Did And no request for a proof, or claim of being one was made (though I would consider it a sketch). I was simply asking why you insistently pointed this out. I am, however, totally "evading" your "request for explanation" after last time: it's ingenuous. If you're just annoyed that the informal answer got accepted, don't wrap it up in a pretension of understanding. If you really are trying to understand I would suggest you ask something more directed, like "I find it hard to understand how part $X$ can be written more formally, as I think you may run into difficulties with aspect $Y$".

@Did Are you saying that one or more of those statements are false? Or you just disapproving of the lack of symbols and/or details?

comment Sparse least-squares fitting of discrete probability distributions
Yeah, well I guess all I was saying is give it a go with whatever package you have to hand. The old do first optimise later maxim. That's been my experience with these things, though not a great answer admittedly. Perhaps someone can do better, maybe on cs.SE or the scientific computing one? Have you estimated how long it will take with standard algorithms?

comment The difference between inside and outside
@Avitus continuity yes, bijective yes, $C^\infty$ not so sure. I was interested in what fundamentally differentiates inside and outside, $f$ was supposed to be illustrative rather than a formal definition.
