Powerpoint corruption and lies Originally uploaded by mahnve.

I am so intensely mad right now. I have spent the afternoon working on a presentation I am to give at lunch time tomorrow.

To make it short: Powerpoint crashes, and takes my file with it in the fall. I can’t open it anymore.

I am redoing my presentation right now - in Keynote.

Coming up with the title of this entry cheered me up a little. You have to know your New Order to understand it.

Really funny: A list of facts about Chuck Norris

(Via Planet Ruby on Rails.)

Cameron states an excellent release numbering system, coincidentally the same as we used back in the days at Lecando:

• A ‘dot-zero’ release (like 3.0) is allowed to drop deprecated APIs, change an API in a manner that could break binary compatibility, or change the JDK version requirement.

• A ‘dot-X’ release (like 3.1) is only allowed to add features and APIs, but should not break any binary compatibility.

• A ‘dot-X-dot-Y’ release (like 3.0.1) is a service pack, designed to correct specific problems, and not to introduce new features.

Mule is a very different beast to me. It seems to be a swallow anything messaging bus where you can message anything anywhere using any protocol anytime. It seems really cool - I just wish I knew what to use if for. This is not at all to say that it has no use, it is just me that has not worked with anything similar before.

BTW: Demos involving messaging are almost always cool.

I have 16 minutes left of my prepaid wireless connection, and I don’t feel like paying more for it. I have covered a few sessions for which the amount of text is too much for the network to handle, so I’ll post it when I get home. I’m right now listening to Scott W Ambler who is really an excellent speaker. More on him later.

Linda DeMichiel together with Mike Keith again walking us through the new EJB3 API. I must say that I like the idea of the one, true, unified O/R mapping framework. Also providing a decent set of default values id really smart - the table mapping is reminiscent of Rails. I wonder what all the app server vendors think of the fact that it can be run outside of EJB? This is another reason that you most probably can get by with Spring in most cases which really must upset the app server vendors and especially JBoss.

Javapolis is held in a combined conference center / movie theater complex. This makes for very comfortable chairs, really good audio and no daytime sunlight what so ever. So far the talks I’ve been to have been really good.

It seems that my problem with wifi jas something to do with size - I can send short emails, but not long. Also, it seems that I have to keep my posts short to get them to my server. This for €20/24 hrs :(

This was another packed session, even though according to raised hands less than 10% of the audience actually uses JSF. Maybe people where there gathering arguments to not use it? The talk was very detailed and I can’t help think that JSF seems to be incredibly complex. One advice to get JSF right was to “avoid HTTP thinking”. That is the exact reason why I don’t like component based web frameworks.

EJB intro with Linda de Michiel. I remember listening to Linda presenting EJB2 at JavaOne 2000 saying that now they had fixed everything that was wrong with EJB1. I must say that is quite a deja-vu listening to her talking about how EJB3 fixes everything that was wrong with EJB2.

The first talk I attended was More Java Puzzles with Joshua Bloch and Neal Gafter. While I normally find these kind of questions way too C++-ish (“can you tell what this piece of unreadable code does?”) Joshua and Neal presents it very well. I got four out of eight right by the way.
