Hello, for a new Yuki & Moto Press book titled “Ruby Compared with Other Languages” I’m reformatting/republishing the evergreen classic titled “10 One Liners to Impress Your Friends” orginally posted in 2011 to show off Scala to pre Java v7 devs - now in the updated version incl. Ruby • Perl • Python • PHP • Erlang • Java • JavaScript. Show off Ruby to your friends :-). Cheers.
