Today on JAOO has also been packed with interesting talks. I attended these:
Failure Comes In Flavours
This talk by Mikael Nygard (who is not danish, by the way, though his name resembles a danish name pretty much) was divided into two sessions. In the first, Mikael talk about anti-patterns that lead to failure - such as depending too hard on third parties, or waiting forever for some external call. This talk featured some "war stories" about failures Mikael had helped to resolve in the past. In the second session, Mikael offered his advice on how to avoid failure and some patterns that can help in this. Though focus was very much on big enterprise SOA systems; the principles can be applied anywhere. I learned a thing or two in this session, that can be applied to my every-day work on web applications in a smaller scale.
Not your Grandfather's Architecture: Taking Architecture into the Agile World
In this talk, James Coplien talked about Agile architecture. He presented his ideas about adding roles as a concept to the object-oriented world of classes and objects. He argued that programs could be made simpler and get rid of polymorphism using his approach; I am not sure that I agree. There was no working code demo, so his ideas is still kind of abstract in my mind.
Successfully applying REST - Integration, Web-style
Stefan Tilkov talked about REST integration; a subject that I find very interesting, since we already use it in projects at work, and are planning to use it even more extensively. Stefan had some very interesting points about REST, and how it can be applied to a SOA world. I really like the clean interface you can make of a REST service, without much of the overhead and scaffolding that is neccessary in SOAP, for instance.
Top Ten Software Architecture Mistakes
This was a talk focusing on what not to do in architecture; so that we can avoid mistakes or bad decisions in our architecture. The talker, Eion Woods, had his list of 10 mistakes and how to avoid them, which was presented with a little bit of humour. At least some of the items is going to be on my list of things to check before beginning development of new projects.
