On the Inviqua techPortal today they've posted a wrapup of this year's Dutch PHP Conference that just finished up in Amsterdam. Rowan Merewood shares some of his thoughts and experiences at the event.

Amsterdam is most definitely one of those cities that everyone should visit at least once in their life and I can highly recommend the Dutch PHP Conference (DPC) as a reason to make that visit. This is also the second year that DPC has been joined by the Dutch Mobile Conference, a ticket to one gives you access to the other. This leads to a great mix of developers from different disciplines and generally means that regardless of your particular skill-set, there will be a talk running whose subject is completely new to you.

He walks through the (non-tutorial) days of the conference mentioning a few of the sessions (covering things like domain models, Lisp and hypermedia in APIs). He talks some about the keynotes - Google's Ade Oshineye on “A Web of Identity”, Eamon Leonard's "Growth Hacking for Humans." and Kevlin Henney's "Worse is Better, for Better or for Worse" He also gave a talk himself about sorting and searching algorithms

On the Ibuildings techPortal site, they've posted the latest episode of their "DPC Radio" series (as recorded at the 2011 Dutch PHP Conference) - Rowan Merewood's session "TDD and Getting Paid".

Test-driven development is generally regarded as a good move: it should result in simple decoupled design, your tests tend to cover behaviour not methods, and far fewer bugs. However, just getting unit tests in on a real, commercial project is hard - switching to TDD is even harder. [...] So, instead of beating ourselves up about not being perfect let's look at an interactive approach to adopting TDD principles. We'll look at tactics for selling TDD to your client, boss and colleagues. This talk will also cover methods for making TDD easier for you by showing you what tools you can use to integrate it into your development environment.
