Nitpick for the author: it looks like you've got (a,b] when you actually mean [a,b). Either that or change the ≥ to be >.

If you mean the tables in the https://eddie.codes/posts/pandas-should-go-extinct/#i-have-b... section, it looks like those came straight from the Amazon paper, in which case __eddie__ shouldn't fix them, on general "quote accurately even if the quoted document has mistakes in it" principles. (Though a [sic] might help).

Sorry, where are you seeing this? In one of the code samples?
