Finally!

After about 8 years of trying (not fulltime ;-), I FINALLY got an RMI example to work. And with that I mean working as it should by transferring classfiles, not cheating by putting the classfiles of the server on the clientside.

In 2002 I understood the concepts in about 15 minutes and the rest of years was pure frustration on crappy tutorials and technical details (trailing slashes, classpaths, codebases, security policies). I tried to find my original 2002 posts on the Sun developer forums but they are either archived or banned. My point was then and still is now: if you can't get a HelloWorld working in 15 minutes (ok, 1 hour) then the technology won't catch on. I've seen plenty of students give it a try and I couldn't blame them when they quit.

Glad I can put this one behind me, let's move on to other things now. I have a whole list for the coming holiday ;-)

Update: : http://java.sun.com/docs/books/tutorial/rmi/index.html was the most useful tutorial

Karlstad university

I visited Karlstad university (Sweden) with some colleagues last week. It's a former Högskule that has transformed itself into a university with a lot of research activities (and funding!). This took a long term effort however. I can imagine this is the vision our rector Henk Pijlman has of the direction the Hanze should move into. My estimate is that it would take 10-15 years of concentrated effort, a lot of it on the personnelmanagement side.

We met some nice and interesting colleagues (Anna Brunstrum, Donald Ross, Martin Blom) and discussed collaboration possibilities on agile among other things. I got a nice idea about the coding dojo which I would like to give a spin next year. Finally we also went to the Compare Testlab and met Sven Wedemalm.

Universidad Polytecnica Madrid

Last week I did my first Erasmus lectures. I was invited at the Universidad Polytecnica Madrid to give four lectures. As the topic I chose agile software development. This obligation had as an effect that I prepared pretty hard, developing new teaching material and learning even more about scrum, kanban and lean in the process. I now have a new case study which I really like and I hope I can reuse in on other occasions. UPM would probably like me to come back next year, I'll have to check with my boss and the internationalisation officer if that's feasible. Once you go international, there are so many places to choose from.

What more can I say about the experience? Madrid is nice, the spanish people are friendly, the country doesn't differ that much with the Netherlands, except for their eating schedule. The students were about as I expected: stronger on the theoretical issues, not very experienced on the practical side and they need to work on their English.

Thus I have finished another challenge to myself. The hardest part was the preparation. But you know what they say: "Train hard, win easy" :-)

Busy times...

These are busy times, I need a lot of time just to keep my todo-list up-to-date. So Keeping up with IT is more Learning on the job at the moment.

Internationalisation

• Tomas Gustavsson from Karlstad University is coming over to give a workshop on Scrum, with the emphasis on starting up a project.
• A delegation of Fachgymnasium Papenburg is coming over to discuss whether our studies are interesting for their students.
• In March I'll go to Universidad Polytecnica de Madrid for a week to give some lectures on agile software development. I combine this with mentoring Hanzestudents who are doing their graduation work there (on the subject of Google wave).

Research
Research? Not really research yet in my opinion. I'm involved in the NOVO-project (see earlier posts) but at this point it's about system development. Requirements, use cases and architecture are starting for real now. The build team (Q3+Q4) will consist of 3 students and we'll be using Scrum.

Curriculum Development

• I'll need to update our 2nd year software engineering course with more multithreading because of the "multi-core revolution". Also, our strategy of intensifying the 1st year has led to material going from 2nd to 1st year. This creates room for some other topics!
  
• Software architecture will be added to our 4th year, a non-trivial job.

Accreditation
For the accreditation our institute will be visited by Hobeon in the fall. This means there's a lot of work for us to get ready.

Honours
I'm participating in the project group that's developing a honours course for excellent students. After some brainstorming we've got the right ideas. Now we have to see if we can match them with the 'guidelines' that came down from Hanze central.

And I still have a buildtool/continuous integration server on my wishlist. But I'm afraid it will have to wait some more...

Just a thought

We used to have the slogan De student centraal (The student is central, focus on the student, etc. ) Yesterday one of our eductational advisors said to me "That's history. A better way to put it is, Het leren van de student centraal" (The learning of the student is central.)

Don't ask your child what he (she) did today, ask him what he learned today :-)

Scrum Master

I just had two days of training on Scrum by the guru himself (Jeff Sutherland) and Serge Beaumont (Xebia). After doing XP for a while, I now can complement it with Scrum and have two legs to stand on ;-) I won't try to give a full account here what Scrum is, but it doesn't really cover the same stuff XP does. In one sentence you could say it's "extreme projectmanagement", or just "a framework for getting things done". The final goal is to get your team into "hyperproductive state".

The training was ok, I'd give it a 7.5/10. The material could have been presented a bit more structured (tell 'm what you're gonna tell 'm, then tell 'm, then tell 'm what you told them) but the content was ok. I appreciate the fact that they tried to support their story with data and referring to literature.

Completing this two day course (+exam) makes me a "Certified Scrum Master". After some more experience you can become a Certified Scrum Practitioner. Personally I would have switched those titles, but it's probably for historical reasons.

Already the next morning I noticed that I was unconsciously using some of the stuff. What's the business value of my wife opening the curtains when her goal is to get the kids to school on time? What's the business value of discussing a student who wants to enroll when he has missed the first 2.5 weeks of a quarter?
Let's keep this way of thinking and see if I can enter a hyperproductive state ;-)

Today was another edition of the JFall. I took the light version by skipping the keynotes and not trying to score every goodie there was to get. ;-) As it turned out my programme had a high "Google" percentage. Coincidence or is the influence of Google spreading ever more?

I started out with "How to introduce Agile in my organisation?" (Erwin vd Koogh, Xebia). No revolutionary insights but a few nice twists to remember. The magic formula is Action = Pain x Budget and developers have to learn a new language (Businessy).

After that I took the hands-on lab on Google Android by Siarhei (Sergei) Dudzin. This worked like a charm and in 1.5 hours I got the feeling for what it takes to develop an application for a Google Android phone. What strikes me is the perfect documentation that Google has as compared to your average open source project. Of course they have the budget, but they really put in the effort.

The next one was about "five star projects" (Eric Bouwers, Software Improvement Group). Apparently there now exists an official certification for software maintainability by the German company TÜVit. This certification ranges from 3 stars to 5 stars. 1 star is rubbage. The SIG performs the investigation for TÜVit. Just as in education the accreditation institution is also seperated from the investigating institution.
The speaker demonstrated the metrics on several open source projects.

Java and Google App engine (Jettro Coenradie, JTeam) was the poorest talk from my perspective. Too little concepts and too much code and XML flashing by. "This is easy, this is just as easy, this is almost too easy to show." Apparently he had some other audience in mind than me.

But this was compensated for by the last talk on Google Wave (Jos Dirksen, Atos Origin). I'm already "waving" but this talk showed me a lot more features. Most people (including myself) start by using it as email, but it can do so much more. The big question at the moment seems to be how you want to use it once you've explored the many features.
Jos also showed how to build your own bots and gadgets. I hope I will have some experimentation time soon!
