Some links to things that don’t fit anywhere else: Andreas Ohlund’s talk on New and Shiny things in NServiceBus 3.0 is available here. By the way, we’ve now got a beta out of NServiceBus 3.0 – get it here. Yves Goeleven will be giving a talk on simplifying distributed application development with NServiceBus and the...

Scalability is a topic near and dear to my heart. Many a client seeks me out for the first time for help in this area. Usually the request is for an amount substantially smaller than infinity. It’s usually on the discussion groups and in conference presentations that infinity is brought into it. The basics The first issue with scalability...

In my courses and conference presentations in which I mentioned the use of MSMQ, I usually state that it comes installed on all versions of Windows going back to Win 2000 (unlike other queuing systems requiring an explicit install). Although installed, the MSMQ service does need to be turned on. Anyway, it turns out that in [...]

Last month both myself and Eric Evans spoke at a conference run by the International Association of Software Architects (IASA) in Madrid. Eric talked about DDD and I talked about CQRS. While the talks were recorded, I don’t think they’ve come online yet. At the end of the conference, we were interviewed by the local .NET [...]

Following my recent post on Datasets and O/R mapping, I've received some comments and one in particular I wanted to call out. Jacob Proffitt, the Rabid Paladin, wrote up a post on how to handle DbConcurrencyExceptions when using datasets. 4 different ways, wow. I don't think that any of them would work if the same row got 2 (or more) updates...

Well, I���m on my way back from Germany now after two intellectually-filled days at the Prio Conference in Baden-Baden. I finally got to meet Ralf Westphal with whom I���ve been emailing back and forth for over a year now. I saw Christian Weyer and Dominick Baier again after meeting them at TechEd Developers Barcelona. You can imagine that the...

Late one night over drinks at TechEd Developers in Barcelona, discussion among the Israeli delegation (Noam King, Alon Fleiss, Yosi Taguri, and myself) turned to SOA. I swear I didn���t force them into it. Anyway, after some debate over what does and does not constitute a service (we all agreed that functions that accept or return XML over HTTP...

Yesterday I got an email from one of my enterprise architecture friends asking me what I thought about the relationship between SOA and EDA. He explained that this question was rooted in article he read on the subject positioning SOA firmly out of the EA space. After reading the article in question I remained firm in my belief that SOA is EDA...

The other day I ran into a blog post titled ���Master Data Management ��� just another load of inaccurate data?��� and got this feeling of deja-vu. This idea of having a single location where the authoritative definition of an entity lived is not new. Enterprises have been going back and forth on the continuum of centralization-distribution for...

After being invited to speak about Software Testing, as well as Software Version Control at the Prio Developers conference in Germany, I thought that I'd prepare for my presentation by first writing down how I learned about testing. This whitepaper is the result of that attempt and has been a great tool in getting the developers I work with to...

Here's another question I received quite some time ago that has some food for thought in it. Wes asks: "I���ve built up a service framework in which various service definitions (capabilities) are exposed as web services which are connected via a service bus. I have two public interfaces that communicate with the service bus, an asp.net 2.0 web...

I received the following question from Houman and I thought the both the question and answer deserved some more public discussion: "Hello Udi, I really enjoyed reading your article on MSJ, thanks. I have been trying to get a handle on the trade off between consistency and availability in distributed environments. I feel that it is closely...
