Kudos if that's the case. An essay on soft skills is probably the most difficult genre to master for a non-native speaker, more so for a programmer. I'm ok with the piece, as long as there was effort involved and it's better than Google Translate.
I've been reading antirez's writing for a long time and he's been consistently getting stronger as a writer of English. I think this is some of his best writing yet in terms of grammar and use of the language.
