Raba - Defend your code RSS 2.0
# Monday, April 14, 2008

Almost a week after tech-ed but It's better late than never.
Very early this morning we start our way to Eilat, the gang of four I called it, Gabbi Soler (aka. MC. Soler), Doron Yaakobi, Yoav Michaeli and I.

    
     Night before TechEd                   Doron at the morning of The first day


This 5 hours were tremendous, sunny day, cool partners and great subjects for talking, we argued almost about everything, the only thing we agreed about is that we are not agree about anything. Here are some of the subjects for debates:

  • Design using UML VS. Test driven Design Vs. Word-API-design
  • SOA as a one-entrance-point to (varying) many applications Vs. One Big Application
  • Project management - what are the management differences between a small project to a large(huge) one - from  scrum-lovers point of view

The next 3-days are going to be a great fun, as a beginning enjoy the view:

                            The Beauty of Israel #1 - on our way to Eilat


                                 The Beauty of Israel #2 - Still on our way to Eilat...

After almost 5 hours of driving (by Yoav) we finally got to Eilat, at the registration point we got a laptop-bag as a welcome-gift and we went to the opening plenum.
Than we finally start learning, here are the 3 lectures I chose to be at for my first day:

Odyssey in SOA - A Voyage through (by Manu Cohen-Yashar)
Manu explained about the SOA using the MS Tools around us, there are plenty of them and I am sure that such lecture is a great start for the SOA & S+S 3-days-session.
Some of the buzz that were thrown out there are: using ESB for Dynamic routing instead of coding that solution by yourself, I've heard for the first time about ISB - Internet Service bus and Oslo as MS-new-to-come solution. Manu also demonstrate a cool tool by AmberPoint here are some of their products: SOA Monitoring, AmberPoint Express.
Those products can show you everything you would like to know about your services even time of calling, number of errors and flow of calls of each message, this tools can solve many problems when using WF & WCF together. anyway I like the lecture, it was a good start for me cause we are start using WCF & SOA in more places at our systems. anyway there were samples that I wanted to see its code or WF Creations it could be even clearer than its explanations.
My grade to Manu's lecture: 8/10.

 

SOAP\WS* and REST (by David Chappell)
David Chappell had a great show at teched He is a great presenter and he knows how to take some boring subject and make it interesting.
The lecture was talked about the two approaches for Web-Services, the WS* approach and the Rest API. When using WCF you are using, in generally, the WS* approach, with this approach we can choose to use the Reliability, Transactions, Policy etc., but we never asked whether we really need all this stuff in our Web-Services? If your answer is not, so why won't we decrease the size of the request and the response and have something more human-readable such as: REST, (you can read more here).
You can use the simply URI and HTTP methods (Get, Post, Delete etc.) and get back a simple XML, RSS, Json etc. there is no need to send or receive Soap Messages.
In WCF you can easily use the WebGet, WebInvoke, and the ResponseFormat property. I Recommend you to search for the lecture presentation, I would post here link when I'll find it, anyway this is what he said as a conclusion: Rest - can be a good  choice for exposing data over web services, SOAP - can be a good choice for exposing logic\operation.

                      David Chappell in Action - Explaining its lecture agenda.

My grade to David's lecture is 10/10, maybe this is because of the accent-charm but it is a must lecture for those who want to learn about the REST and the WCF connectivity.

 

SQL Server 2008 - what's new in Analysis services
I believe in knowledge, I also believe in learning more tools\products\architecture, so I went to this lecture from the BI session, after half an hour I've found this boring while the presenters only compare between the 2005 to the 2008 version, so I can't even give a short description from this one.


        This is me picturing myself, before the cocktail party (or maybe after...)

After this lecture we went to the cocktail party where I first found Oren Ellenbogen and Aviel. I really missed Oren and it was great to see him and lots fun with them both.

More on the second day at my next posts.
