YamlInFiveMinutes: I mentioned YAML a couple of times in a prior post, and while looking for a good link, I found this little tutorial. It’s quite good, and, true to the title, it’s short — I think I got through it in four minutes.
YAML is so much nicer than XML for simple serialization of data. It’s much more human-readable. Rails (and Ruby itself) are very infatuated with YAML. You see it much more than XML in those frameworks.
