Currently I'm working on something that needs to recognize threads from email conversations. An easy way would be to rely on a specific token/reference being present in the Subject. However to allow users to change email subjects without losing track of the "thread", we need to rely on using email headers, specifically: message-id, in-reply-to and references.

These headers are best described in RFC 2822 (Section 3.6.4)

Hey, I just found out from fellow-ThoughtWorker Ola Bini that the creators of various Ruby implementations are having regular Ruby Design Meetings. Ola has blogged about this: Ruby Design Meeting.

You can even check out the chat meeting transcripts here: http://ruby-design.pbwiki.com/Design20080421

I hope to learn a few things by going through the transcripts. It's like being there with all these amazing folks!

It all started when I wanted to test equality for a Ruby class I was writing without wanting to expose its state (ie, data members and their values). It is different from doing the same in Java: in Java, the concept of 'private' is applied at a class-level, ie, two instances of the same class can see each other's private fields (from within methods declared in the class containing the private fields); in Ruby, however, 'private' is applied at object-level and hence no two instances of even the same class can view each other's private members.
