Ruby Weekly Issue 16
November 18, 2010
Welcome to issue 16 of Ruby Weekly. I suggested there might be some HTML archives in place for this issue; sadly, this isn't the case yet as old issues were written in a different format and I need to finish converting them. Fingers crossed for next week. That said, issues 15 and 16 are available at so far.
