NDC 2010 accept

av: Harald Søvik
Against all odds (?) - Mortens and my paper ("Modularization, Testing & Technical Debt in a Large Agile Project") was accepted for the Nordic Developer Conference 2010. Well then, even though it's experiences from a Java project presented at a .Net conference, both sides has the agile dimension in common. But it's still somewhat comical to present in "the dragon's lair". The presentations is scheduled for day 2, track 2 at 11:40 - in parallel to Eric Evans .. yikes. The abstract reads: This...

Twitter programming session

av: Harald Søvik
Last night I had a live programming session with ~30 CS students at the University of Oslo. The goal was to show how easy it is to interact with RESTful webservices in Java. I started out with explaining about HTTP and Jersey, REST vs SOAP, JSON vs XML and jsonlib vs jaxb. Those were the major design decisions. I subsequently implemented a bot that would befriend anyone that was following the bot. Doing this with jsonlib was pretty straightforward, but showed the weakness of not having a high...

Scrum and Technical Debt

av: Harald Søvik
This years Smidig-conference is over, and I've had a week to digest the impressions. Overall it was a great experience. Lots of lightning talks, open space discussions and even some beer. My talk on Scrum and Technical Debt created some fuzz in the following open space discussion, so I guess it must have stroken s chord in some of the listeners :) Janniche from Bekk challenged me on my claims, and frankly I think she may have a point. She argued that if tech debt seems to hide away in scrum, ...

Presenting a RESTful web service

av: Harald Søvik
Lately I've been pondering on how to create a unambigious description for the RESTful web service I am designing. The kink is to create a description that will work both ways: For consumbers AND producers. In addition it should be easy to maintain and develop. So I figured that there is a description language called WADL - Web Application Description Language. Suitable for REST they say. Great indeed, but as it is not a formal standard, there are very few tools supporting the format. I.e....

JavaOne 2010 day 2

av: Harald Søvik
Attended a great session on ESB best practices by Earl Nolan and Monal Daxini. Then some REST stuff of various quality. The big thing of the day was the general technical session with Mark Reinhold. Most of the presented material were old news: Java SE 7 and EE 6. I guess the value of it is to say it's still in the pipeline. SE7 is now planned released in 2011 and SE8 in 2012. I.e. lambda expressions has been postponed till the 2012-release. The session also had a nice and rather technical...

JavaOne day 1

av: Harald Søvik
What's better than a day full of Java? Such a day, and an BOF evening cruise on the bay :) Contemplating on how many participants there are on these conferences, we figured about 60 000. That's a lot of hotel rooms being occupied, dinner services etc. But then there's not a room available anywhere in the city. Wonder what happens when everyone goes home on Friday ..

Yess! I'm here at Hilton Hotel, San Francisco, ready for 5 days of concentrated Java juice! Tonight at 0530 pm Larry will kick off the show, and we'll be ramlin' down a path of tech discussions over an Anchor Steam pint. This will definitely be awesome!

Knowledge sharing days

av: Harald Søvik
Today is of our knowledge sharing days in Computas. I haven't reflected on the actual value of such days before, except the practical value of giving and attending lectures and talks. But today I discovered that there is actually more to it than just the knowledge sharing. Being away from your current project, you get to reflect on things that are not immediatly useful to your work, but rather expands your horizon on other topics. Such a day differs from a day at a conference in that you feel...
