If you need to process 1000 items independently, the simplest thing to do is to handle them one-by-one. But what if there is a large delay that is not caused by your application when you handle an item? What if you need to make a 100ms web request per item, only to do about 10ms of processing on that item? This would take 1000 x 110ms (100ms to wait, 10ms to process)!
So what do we do?
I just submitted to the for the .
It solves the problem of having your AIR application store an IExternalizable class on disk but then later adding more fields to that class. How would you read the old version of the class without encountering a runtime error if you tried to read the new field that wasn’t present in the older serialization?

The specifics are very difficult to explain, and we’ll summarize them at the end after trying out some examples. Fire up irb and give the following a try.
require 'yaml' s = "\n Something embedded.\nAnd on a new line." YAML.load(YAML.dump(s))
