Last night, Thoughtworks was hosting an public event @ Japan Center, Frankfurt – right next to the EZB and Deutsche Bank headquarters (I sure hope that those buildings were filled with busy & smart people working on setting things straight with the Euro).
- 18:45 – Welcome by Nick Ashley, MD of ThoughtWorks Deutschland
- 19:00 – Wolf Schlegel: “Dos and don’ts of Continuous Integration and Delivery”
- 19.20 – Erik Dörnenburg: “Lean for enterprise architecture
- 19:45 – Martin Fowler: “Software Design in the 21st Century”
- 20:30 – Networking – drinks and food
Unfortunately, I missed about half of Wolf Schlegel’s talk on Continous Delivery, but judging on the second half, I would have preferred more in-depth discussion of technologies and best practices. The talk seemed like a space-station’s eye view of the topic.
Erik Dörnenburg was next talking about Lean Enterprise Architecture. I very much liked his analogy of comparing the role of a Software Architect to that of a Gardener instead of a traditional Architect. Spot on. Quite a few interesting thoughts on how to causing change in an organisation / team, too.
I was quite keen on the Domain Specific Language part, as we’re currently moving away from a “home-grown” Domain Specific Language for NC-code templating & output to a Python-based solution as we found that our own language lacked the expressiveness we are looking for. My key take-away was that there are two ways to create a DSL, external & internal and that we’re migrating from an external DSL to an internal DSL. Looks like the DSL book is supposed to be on my reading list real soon now.
Martin’s thoughts on “Nondeterministic Tests” were especially interesting as I was attending a talk on “Unit Testing & Concurrency” right last week in Karlsruhe. Very interesting to see the different takes on the topic – Abstracting away the concurrency altogether for unit testing purposes whereas Martin was leaning towards integration & acceptance testing and giving very sound advice on how to deal with concurrency issues within the tests (polling, callbacks, test doubles).
As you might have imagined, I mostly skipped the Networking part due to my sociophobia.
Overall, a very worthwhile evening and I very much look forward to future Thoughtworks events.
