Ask HN: What features do you miss in Google Docs for desktop?

(I don't work at Google. I just hope some Googler reads our answers and submits feature requests based on them :-)I often write documents in Google Docs on my laptop. Every time I open a new document, I change the font from Arial to Lexend and set the size from 11 to 14 points. I wish Google Docs would just remember my favorite font.Sometimes I insert special characters into my documents. The...

The first and second principal components (joy-sadness and anger) explain only 41% of the variance. I wish the authors showed further principal components. Even principal components 1-4 would explain no more than 70% of the variance, which seems to contradict the popular theory that all human emotions are composed of 5 basic emotions: joy, sadness, anger, fear, and disgust, i.e. 4 dimensions.

Interesting. Apion's description of the pessoi game mentioned in the Odyssey: flicking pebbles toward the Penelope-pebble convinces me more than translating pessoi as draughts. The problem with Apion's description is:

- There were 108 suitors (we know this from the Odyssey 16.245-254 [1]).

- All that Homer told us is: They were gladdening their hearts at pessoi in front of the doors, sitting on the hides of oxen which they themselves had slain (the Odyssey 1.106-108 [2]).

- You can't have 108 sitting men play the same game of marbles.

IMHO, pessoi was a 1:1 game and it was not a board game.

A recent blog post on thatsmaths.com was about Tonenetz, a diagram of harmonic relationships of notes. Tonenetz means 'tone network' in German :-)

> a quaternion is a 4D representation of a rotation in 3D space

A unit quaternion represents a rotation in R³.

A quaternion represents the quotient of two vectors in R³. That's what Hamilton had in mind.

I took the liberty to replace my awkward wording with your "the result in column i and row j is the sum of product of elements in column i of the left cracovian and column j of the right cracovian". Hope you don't mind. Thanks!

Author here. There are no practical advantages, as far as I know. Not even faster multiplication on today's computers.

Thanks for the feedback, everyone. I pasted my Polish text into Gemini to translate it into English. Gemini hallucinated the translation of this example. Now it should be OK.
Re:Virality in cartography: What makes a map go viral? on Friday November 15, 2024 @01:22PM (#42149477)
My map of the most frequent occupational surnames in Europe [1] also went viral in 2015. When I posted it on Reddit, newspapers from Ireland (they asked me for permission to reprint it) to Greece (nobody else asked) and countless people on Facebook republished it. Well, everybody has a surname, an occupation, and a country.

Late advice: when making a viral image, put your URL on it :-)
