I have been spending most of my free time working on a Rails project for the Mary’s Place day shelter. At some point - probably after many scan/edit cycles with metric_fu – it occurred to me that even though my Rails knowledge has increased over the last year, my core Ruby skills have not. They have stayed static. They may even have deteriorated a bit, since Rails does so much work for the developer.
This seems like a perfect opportunity to reread the Pickaxe book Programming Ruby. This might not count as a reread, though. I have not read it cover to cover since the second edition came out. They are on to the fourth edition now.
