(author here) Me neither! Don't know how or why it suddenly appeared on the HN main :)

Just to provide a bit of the personal context: this article caused creator of DaRu (Sameer Deshmukh) to contact me and propose to work on DaRu together, and so I did (see @zverok here: https://github.com/SciRuby/daru/graphs/contributors). I also was, for some time, SciRuby/DaRu's mentor for Google Summer of Code (and, IIRC, it was my initial idea that daru-view grew from).

Also, since that article, an independent dataframe library https://github.com/ankane/rover was created by Andrew Kane, handling some of API and implementation in a cleaner way.

That being said, I am not sure that DaRu, or Rover (or "dataframe" idea in general) has enough visibility in the Ruby community. It is mostly thought as "some special scientific thing", while I believe in 2021 it should be seen as one of the necessary everyday high-level datatypes.

That's what I'd focus this article on if I'd written it today.

And I add that just the datatype is not enough, because is "this close" to be the foundation for relational programming (p.d: I'm building a relational language where you can say everything is alike data-frames/relations: https://tablam.org).

This is part of the problem, truly. Being so focused on "science" when I think is better to frame it as data manipulation like you do in SQL tables/views, making it much more general than is used for...

Thank you for the update.

I agree. It is one of those data structures that developers tend to use by reimplementing badly using arrays/lists and dictionarys, usually even unaware that they are doing so.
