Yesterday I had a Power Workshop (6 hours) about large projects with PHP. You can find the (German) slides here.
Besides that, there were some very interesting talks in the evening at the hotel bar together with the almighty Stefan Esser, Christopher Kunz and Johann-Peter Hartmann. Today is the second pre-conference day, at 10.00 o’clock I will give the opening talk at the Management Day (with speakers from IBM, eBay, SAP and others) about the business opportunities with Web2.0 and PHP. Tomorrow, the main conference will start with a lot of great sessions.
