Sorry, but yesterday I simply didn't had the time to write my review for the Techdays' second day. So, here it goes, one day late.
INT04 - Qual é o Contexto desta Conversação? Activando Conversações Longas em Serviços de Workflow. Serviços "Duráveis" (link)
This was the second session, that I saw, presented by José António Silva (see here and here). Again, he presented it well although it wasn't supposed to be presented by him (in his words). But, like he said, he really wanted this session to be presented. And he was right. Back when the WF and WCF were released for the first time, there wasn't any integration between them. but with the .NET 3.5 release it's possible to expose our workflow as a service. He explained that was possible using the extensibility architecture available in the WCF. This is known as Workflow Services.
ARC01 - Software + Services: The Convergence of SaaS, SOA and Web 2.0 (link)
Without a doubt, one of the best sessions that I have watched in this year's Techdays. Beat Schwegler is awesome! Bruno was right when he recommended him to me. He basically went thru three basic topics: SaaS, SOA and Web 2.0. All that sum together is equal to S+S. Then he covered how we can build an S+S application, run it, consume it and finally how to monetize it. One example that he gave a really big focus was on the Eve online. Other examples were the Microsoft's Photosynth and the British Library's Turning the Pages. A really great presentation.
INT06 - Viagem ao Centro da Núvem – O Internet Service Bus (ISB) e os BizTalk Services (link)
in the first day, Jota brought us an explanation of the Enterprise Service Bus (ESB). This session was a continuation of that. He said that the Internet Service Bus (ISB) is an evolution of the ESB to cloud computing. The Microsoft's implementation is known as BizTalk Services. Thru that, the messages are sent to the ISB and who is subscribed in the ISB same address receives it. The technologies beneath it are the WCF (for the connectivity), CardSpace (for the authentication) and the Workflow (not yet implemented). One of the main advantages is that the communication can pass over NAT. Also it can be a major disadvantage because it raises some security issues.
I've already have something in my mind to try this out :) ... Oh and yes...Jota once again didn't disappoint us. He's really good!
INT03 - Construíndo Soluções EDI/AS2 com o Microsoft Biztalk Server 2006 R2 (link)
I'm truly sorry for Rui Pereira, but this session was very boring. He could have made it little more interesting. Basically he went thru the EDI\AS2 support in the BizTalk Server 2006 R2. AS2 is a secure transport layer built on top of HTTP. EDI is a set of messages schemas, used in many integration systems (I'm currently working in one of them - reason why I stayed to end). In EDI there are two standards: X12 (that's more used in the US) and the EDIFACT (used more often in the Europe). He also explained hot to configure the EDI/AS2.
SRV04 - The Old New Thing: Stories from Inside the Windows Team (link)
I can now say that I'm fortunate to be one of the people that listened some of the stories that Raymond Chen has to tell. He's incredibly funny and is a truly a story teller. He was the responsible for why I wasn't in Tiago's second session. He only had one slide that at the same time was the agenda. It stated: "Tell stories" :)
Sorry but I won't tell any of the stories here.
Until next time;
