Can a native English speaker kindly explain the title? With that many negative tenses, it's really hard to parse the motivation of the author.

It's in the vein of "even if you can't do something, you should to try anyway"

Not ugly is more of a less strong "pretty" and can't not is more of a "should" (rather than "can"), so the title can be read as "you can't make c++ pretty, but you should try (to make it pretty)".

Thanks!
