I agree that persons like Dan Kaminski and their accomplishments should be celebrated.
My point is that the endless stream of posts about death make Hacker News sound more like Hacker Obituaries.
My proposed solution is to add another category, perhaps "In Memoriam".
If we hide these articles under a separate category, everyone who wants to read them (I'd estimate thousands of people, based on the number of upvotes some of them get) would have the extra work of checking that category. It's much simpler for you to just skip over them. And where does it stop? Should HN create a separate subcategory each time someone complains they don't like a particular type of article?
So you're essentially saying: Stop posting these articles because I don't like them? Just skip those articles then. Nobody is forcing you to read them.
But by reading these articles, we can learn about people who shaped our field (some of whom I learn about for the first time when I read their obituaries), what their contributions were, how they overcame difficulties in their careers, and sometimes how they changed the world.
