I think that "Better data" is a reference to gainful compression, and that "my better cat" doesn't specifically refer to the author but to the lyrical subject (as in poems).

Hash tables aren't lossy, maybe Randall means hash functions? Barmar (talk) 17:06, 17 February 2023 (UTC)
- I was thinking more a (subset of) a Rainbow table, than an associative array... Although such things tend not to preserve/respect item order (in reading, writing and altering in general), which is potentially information-lossy. 172.69.79.185 18:50, 17 February 2023 (UTC)
GIF's aren't lossy either, though often other formats can't be converted to GIF without discarding information. Bemasher (talk) 18:27, 17 February 2023 (UTC)
- I think that's the point. 172.68.50.203 20:12, 17 February 2023 (UTC)
Someone needs to add a table describing all the formats in the chart. Barmar (talk) 19:29, 17 February 2023 (UTC)
It seems there are two definitions of data quality that Randall is juxtaposing for comic effect: in one, quality data is data that represents the original phenomenon without error or degradation. In the other, he's applying the concept of quality to the phenomenon itself – data is better if it describes a better phenomenon. My cat is better than your cat, therefore data about my cat is better than data about your cat. I'd like to see this concept in the explanation of the page but don't know how to add into the flow of the current text.K95 (talk) 19:33, 17 February 2023 (UTC)
- I already put that in earlier. See the second sentence of the second paragraph, I called it "general excellence". Barmar (talk) 21:45, 17 February 2023 (UTC)
