For the observation toward the end that compressed files seem highly uniform, this makes sense intuitively. If there were any visible patterns, that would imply that the data is further compressible, which would mean the compressor didn't do it's job very well.

> as.tibble(cbind(x,y,z)) %>% na.omit()

Why on earth would anyone write that instead of na.omit(as.tibble(cbind(x,y,z)))? Baffles me.

thank you for sharing this! i'd like to try and recreate this in R.
