Why is this such a big news? Its logical, any other result with moderate exercise wouldn't make much sense. Hard/long effort will tire you also mentally for some time, again makes complete sense. Deep breathing will also wake you up, to certain point, after that you become dizzy with too much O2 in your blood. Meditation or mindfulness exercise will slower your heart rate and make you feel cold. I could go on and on like this whole day.

Its nice if there is a scientific proof for logical behavior of reality but it shouldn't make big news for anybody here. If there is some proven discovery of at-first-glance-illogical behavior of our bodies or reality, now that's something newsworthy.

I've never heard of this, can you elaborate?

Can anyone comment on the similarities with (apparently somewhat less sophisticated) laziness as in Haskell, or the memoisation/caching done by the Nix package manager, or (perhaps most interestingly) the approach of the Funflow library for Haskell[1]?

This looks interesting. I'm open to replacing my current (actually quite rudimentary) "capture to org-mode" setup. Is there any way to dump all/important parts of the information Memex captures to plain text/CSV/etc, or, say, a sqlite database?

Overall, this is a space I'm very interested in and this looks like a polished product. I'll be keeping an eye on it; I've installed the addon and am looking forward to playing with it :)

PS. "Full-text search" seemed to me (and might to many) like full-text search of webpage contents, not just URLs/titles. It's not malicious, of course, but it feels slightly misleading.

I find it profoundly unsatisfying, but this may be a good starting point for further exploration:

My wife's last name starts with an A, mine with an L. Our daughter is A-L; my wife joked that she wanted to give the baby "alphabet privilege".

It is a thing, and there's evidence for it in certain academic fields. [0] studies this effect in economics, and this would be reason to expect similar things in other fields like maths, CS, and physics where alphabetical surname order on research papers is standard. Modulo a lot of context, replicability issues, and the like (and of course career choices), there's a chance you actually are doing your daughter a tangible favour this way. :)

> Faculty with earlier surname initials are significantly more likely to receive tenure at top ten economics departments, are significantly more likely to become fellows of the Econometric Society, and, to a lesser extent, are more likely to receive the Clark Medal and the Nobel Prize.

> These statistically significant differences remain the same even after we control for country of origin, ethnicity, religion or departmental fixed effects. As a test, we replicate our analysis for faculty in the top 35 U.S. psychology departments, for which coauthorships are not normatively ordered alphabetically. We find no relationship between alphabetical placement and tenure status in psychology.

Flagged. This breaks the Show HN rules: OP is not the creator of this.

I know the author; they shared it privately with friends and weren't ready to post this publicly yet.

Quick note that may be of interest: S² is the mathematical notation for the "2-sphere", aka what we call a sphere in everyday language. I suppose that's explained by this:

> A unique feature of the S2 library is that unlike traditional geographic information systems, which represent data as flat two-dimensional projections (similar to an atlas), the S2 library represents all data on a three-dimensional sphere (similar to a globe).

(S^2 if the superscript character doesn't show up for you.)
