Do i get this right? This discovery let you calculate the minimun amount of grafana dashboards you need to monitor a kubernetes cluster or the minimun amount of dasboards behind you in a linkedin photo to look cool enough?

Yes, exactly. Care to share an example of what you're talking about? You may have found a new realm for research...

Moderators often resubmit submissions with fake time. (I pretty much hate this. I don't like people lying things about me, like I was using HN at a time I wasn't. Be aware of this.)

Why?

As dang explains in one of the linked posts, it's because if they don't do it, the discussion usually becomes "how is this on the front page when it's 2 days old?" instead of discussing the topic at hand.

Of course in this case we're now discussing the opposite question and still not discussing the topic at hand.

It's an invasion of privacy. Imagine that a post appears under your name with a date/time where you are supposed to be working. If you are paid by somebody else, this may get you into trouble, or even fired.

It does suggest that an "(updated)" marker would not go amiss.

I won't explain my justification, since I'm supposed to be working right now. ;-)

Heh. I was not prepared for the punchline that this "only" goes from 4^k to 3.993^k. I mean, they're creating a whole new form of proof that will almost certainly allow further decreases, and they generously aren't holding back until they make a bigger dent, but it just intuitively feels like the true value has got to be way, way smaller.

(On a side note, I am so often stunned by the quality of articles on Quanta Magazine. I sorta thought this type of quality writing was dead and gone from the freely accessible web.)

Fortunately the moderation here isn't a faceless monolith and if you email them they would most likely be happy to cooperate with your concerns about this.

Their YT videos are also top notch.

I get that this is really interesting and I surely enjoyed the read... But has it really any practical implications? I mean, in a sense, there are so many mathematical riddles... Anyways, I'm fine to ignore this question. Very nice!

Before someone jumps at you for daring to ask this question... yes, there are many many math riddles, and indeed not all are equally important, and we may not always know in advance which ones are.

Some turn out to be more "productive" in the sense of leading to development of techniques, connections to other fields, etc.

Ramsey theory (the riddle discussed in the article) is one of these, here is just a short list of nontrivial applications to CS (admittedly, mostly to theory of CS):

You’ve definitely described an invasion of privacy, just not one perpetrated by HN.
