We had little over ten people turn up for the meeting and we had great fun. I admit that the topic was rather esoteric as ESB, SOA, and BizTalk just doesn't apply to all that many people out there, especially in Denmark. ESB and BizTalk was the second part of our SOA topic and I think it rounded the topic off in a nice way. For future meeting we'll try to keep to topic of the presentation a bit more mainstream. Also the next time I plan a meeting I'll make sure not to collide with a major conference in town like JAOO. Having a usergroup meeting right after a full day of conference is a tall order, I know I went there straight after JAOO, I might not have been my most coherent self and it might have affected the turnout as well.

A big thank you goes out to Klaus Hebsgaard and Kristelig fagbevægelse for getting a nice space for us to hold the meeting, probably the nicest yet, and some very good sandwiches too.

Like always we started out the meeting by summarizing what the core group has been up to since last time. First of all we've been busy with getting new talks and speakers together and I'm proud to announce that we've got the next couple of rounds together at this point. I expect that we'll announce new meetings much earlier than we've been doing up to this point to allow people more time to sign up for the meetings. The topic of the next meeting is Object Relational Mapping and LINQ by Søren Skovsbøll and will be held at Ditmer A/S at October 24th at 19:00. Please note that we're not doing the meeting the last Wednesday of the month this time around due to scheduling issues. I'll do a separate post on the next meeting when I've got the last couple of details sorted.

We're planning a couple of meetings which are aimed at the inexperienced .NET developer because we do have a number of you attending the meetings and we'd like for the group to bring something to the table for everyone. As a follow up to that the first meeting we're trying to get a code camp together with the intent of teaching you how to create a .NET application from ground up the right way, or at least the way we feel is the right way. This is not only for the inexperienced developer as we need a number of experienced developers who can act as a kind of instructor at the code camp helping out with questions. I'd like to gauge the interest in this concept so please write me an e-mail if you're interested in participating either to learn something as an instructor.

We're still working on the web site for the group. All the technical stuff is basically done, we just need text and the pretty parts to be done as well.

Like previously we did a quick lap around the attendees to get a feel for who was present. We had a couple of new guys, one of whom had asked me before the meeting whether he could attend even though he hadn't been the previously. So I I'd like to take this opportunity to clarify that Aarhus .NET Usergroup is completely open to all who wish to participate regardless of previous attendance. We'd like you to attend every time of course to ensure continuity but it's completely up to you. You simply sign up to the meeting you want to attend and that's it. If you've attended a meeting previously you'll receive an e-mail whenever a new meeting is scheduled so you have the chance to sign up before anyone else.

Troels Riisbrich Underlien gave an interesting presentation on Enterprise Service Bus and BizTalk. The presentation focused on ESB as a technology and less on BizTalk although he gave us insight into some of the inner workings of BizTalk because they were at the heart of the ESB solution he outlined later on. Troels gave us information on how to go about building an ESB on BizTalk, the Microsoft guidance, and probably most interesting of all how Vertica has created and implemented an ESB for Bestseller. Download the slides if you want to either recap or get a feel for the content of the presentation. Essential an ESB is the way to go if you're considering doing SOA that's my personal take away from the presentation anyway. If you what want is a asynchronous, scalable and flexible solution there really is no way around the ESB as a concept.

After a short break and chatting in the hall ways we went back to the regularly planned programming where Holger Brøns Jensen the CIO of Krifa did a brief presentation on the IT organization of Krifa and the challenges they're facing. Krifa is definitely facing some interesting problems at the moment as they're moving their entire platform to a service oriented architecture, of course they have a lot of legacy which still needs to work so the last two meetings have basically been perfect for their needs. Krifa has done some very interesting stuff in the past and was off to the IP telephony races very early on which provided them with a nice head start on the callcenter side of things compared to their competition. Thanks to Holger for a very informing presentation.

Finally we had the unstructured part of the meeting which we call the Nutcracker. People usually refer to this part of the meetings as the most interesting as it opens up for discussion on various topics. we had a couple of good discussions this time around: Klaus had a problem getting their ESB to talk to WCF and we steered him in the direction of a possible solution. We even got Visual Studio fired up to show him the default binding profile for ASMX, of course I couldn't help but get sidetracked just a bit so I demoed a couple of features of ReSharper a couple of which have actually found their way into Visual Studio without my knowledge making for an interesting demo. Following that I wanted to get people's opinion on ORM and which they use themselves. I didn't really get that one off of the ground but the discussion took an interesting twist regardless so all in all a success.

Thank you to all who attended this meeting. As I started out by saying we're aware that the topic was esoteric and we'll try to keep broader topics of interest in mind for future meetings. I'd like people who plan to attend in the future to think about topics for the Nutcracker so we ca get the discussion going, maybe even prepare a short five minute talk to get the topic going.
