PHPNW 2010 on the w/e 9th - 10th October was well worth attending. Sessions for me after the keynote included:
Let your toolchain set you free
Debugging – Rules and Tools
The curious case of php|architect
Designing HTTP URLs and REST Interfaces
All the sessions where very informative, but the latter proved the most interesting. I noticed REST interfaces kept coming up at the Ruby conferences in '08 and '09 and also in reading about Ajax. So David Zuelke's session was very interesting both with his critique of how REST is applied (twitter) and his humour. I look f/w to the videos appearing.
I have just learned about DrupalCamp Edinburgh on the 30th and have registered.
