From: Corey Lawson Date: 2006-03-04T02:08:10+09:00 Subject: Re: Teaching Ruby to COBOL programmers Also, remember that they're very used to thinking in procedural terms. Don't forget that. Walk them through refactoring a big procedural problem they may be familiar with to a more Ruby/OO solution, and try to explain a bit about the WHY of doing it the OO way. Most of them should appreciate how less hypergolic Ruby is compared to COBOL... If they're mainframe types, there will be some mainframe/COBOL idioms that they may be very comfortable with that they may throw at you in resistance. If you can counter some of them, if only to say, "it doesn't work that way here, but this does the same thing", that could be good, too.
