Ruby Weekly Issue 18
December 2, 2010
Welcome to issue 18 of Ruby Weekly. Reader Alexander Gromnitsky rightly pointed out to me this week that MailChimp - the service I use to send Ruby Weekly - keeps an archive of old newsletter issues automatically. I'm still looking to have them on the site itself, but that should make a good stop gap for now if you want to see back issues (issue 4 onward).
