You can use Clojure to get all the goodness from Java and still have fun

try it!

  data:text/html,A
B
C

afaik to create a CustomElement you need to use dashes, yes, but in this example `` is an HTMLUnknownElement, which renders just fine. some discussion here: https://stackoverflow.com/a/22545622/2393963

Both stories are in the compilation Exhalation, but OP’s description matches what I remember from the story I mentioned more than the one you linked

don't you mean "The Truth of Fact, The Truth of Feeling"? I think that matches your description more, but I could be wrong

Julia Evans has a fun blog post using Julia to visualize Gunzip: https://jvns.ca/blog/2013/10/24/day-16-gzip-plus-poetry-equa...

you should totally do a "Janet writes Janet" version

1x5 can also work if you take advantage of subpixel rendering https://www.msarnoff.org/millitext/

the scarf matches the one Rich is wearing near the end of the documentary. the code matches what's on the Clojure source code, even if it's an odd choice. the two belts are in the draft, even if only one of them features the logo. the artist's instagram has a bunch of well colorized artwork. I believe it is really human made

I don't think it is, considering they highlighted it in a post about human craft [1]. I read somewhere it was illustrated by felipemelo.net, but can't find the reference anymore

The Wikidata documentation is good:

https://www.wikidata.org/wiki/Wikidata:Introduction

And you can find lots of SPARQL examples here:

that's kind of what P800 (notable work) is doing, but you can try some approximations to "major work" with "has both an English Wikipedia page and a Goodreads link":

  ?work wdt:P50 ?author ;
        wdt:P577 ?publicationDate ; 
        wdt:P8383 ?goodreadsID .

  ?article schema:about ?work ;
           schema:isPartOf  ;
           schema:inLanguage "en" .

This is actually a good fit for a Wikidata SPARQL query you can run here https://query.wikidata.org/:

  SELECT ?work ?workLabel ?author ?authorLabel ?publicationDate ?ageAtPublication
  WHERE {
    ?author wdt:P569 ?birth .
    ?author wdt:P570 ?death .
    ?author wdt:P800 ?work .
  
    ?work wdt:P50 ?author ;
          wdt:P31 wd:Q47461344 ;
          wdt:P577 ?publicationDate .
  
    FILTER(?publicationDate <= ?death)
  
    BIND(YEAR(?publicationDate) - YEAR(?birth) AS ?ageAtPublication)
    FILTER(?ageAtPublication > 60)
  
    SERVICE wikibase:label { bd:serviceParam wikibase:language "en". }
  }
  ORDER BY DESC(?ageAtPublication)
  LIMIT 300
