The final day was really interesting. It started with a keynote from Eben Moglen. This got a quite emotional response from most people. After this Alexander Limi highlighted the fifteen most exiting features of Plone 3.
After a short break I went to the talk from Joel Burton about making Plone simpler for end users. He had some really good ideas and ready to go tweaks. A lot of these tweaks should be automatable so maybe I will write a burtonizer product.
Phillip had an interesting talk about viewlets in Zope 2. It seemed really nice but may be a bit difficult for scripters to understand. Although the current macro mess is pretty bad as well.
We had some great snacks during the break. This day they served mediterainian tapas.
One of the days highlights for me was Wichert's talk about PAS (the Zope 2 version). He really made it clear for me where everything goes and what it does. So when I will need to use it I now know what to do. An example of a usecase I know have an idea about how to implement is RSS feeds that need authentication.
Most RSS readers don't understand the Plone login form. So if you want to access the feeds from the reader you need to supply the proper credentials via basic authentication. What we want is that normal users go through the login form and RSS readers use basic auth.
To do this you create a challenger plugin. This can be used to differentiate based on the user agent or some detectable propertie in the url.
The lightning talks were the closing talks. It was fun to see these as they are always fun due to the frantic pace. After these the conference ended. As far as I am concerned this was the best IT conference I have ever been to. My thanks go out to all the people involved in making this happen.
