References and phrases don’t make a culture. The words may change, but the culture here is absolutely the same as Reddit. Which is why it’s so damned cringe when you see someone on Lemmy offer a smug, self-satisfied criticism of some supposed inferiority in the Reddit userbase. That kind of smugness is peak Reddit-culture.
No. Everywhere uses the same terms, you just didn’t understand the question.
The result of addition is the sum. The sum is calculated by summation of inputs.
The result of multiplication is the product. The product is calculated by __________ of inputs.
OP’s question is: why can’t the blank be “production”, by analogy with “summation”?
“Summation” already means something else, and funnily enough words can have different meanings in different contexts without causing any confusion.
OP literally emphasised the distinction between process and result in their post, specifically so that this exact confusion would not occur, and yet still everyone is talking about the word for the result instead of the process.
I don’t follow any blogs particularly consistently/regularly, but the one that I find myself coming back to at intervals is Raymond Chen’s The Old New Thing. It’s got a pretty heavy programming focus, but also occasionally covers interesting little trivia from Windows history. I’m not a professional coder, and I no longer even do any coding as a hobby, so take it from me when I say that there’s content of interest to programmers and non-programmers alike.
