Tasting Beer in a Smelly Town

The title of this posting probably sounds like a silly joke, but Moss is famous in Norway for "Mosselukta" (the Moss smell). As soon as I stepped off the train I could not only smell it, but also see the factory chimney from which it issued. The cellulose factory of Borregaard is located in the centre of Moss, and spews out sulphurous fumes that smell faintly like rotten eggs. It used to really stink up the whole town, but in the last decade or so it has gotten better. Still, not the best conditions for trying a microbrewery with outdoor serving, but having spent 40 minutes (and 200 kroner) on the train, I gave it a try anyway. ...

Equivalence classes

I've been doing some thinking about identity lately, but to explain myself I need to first get across the concept of an equivalence class. Equivalence classes for me are one of the wonders of modern mathemathics, in the sense that it's a concept that's brilliantly simple, obvious, and elegant, and at the same time incredibly useful. ...

Geir Ove Becomes a Blogger

My friend and Ontopian colleague Geir Ove Grønmo (yes, he of the fridge and the typed data) has started his very own beer blog. He's a dedicated home brewer who has been brewing for at least three years already, and even won a first prize in the Norwegian home brewing championship before he started brewing stuff that was too hard-core to appeal to the judges. ...

How to Understand Beer

Most people who are not into beer tend to divide beer into two types: normal and dark, and they'll tell you things like "I don't like dark beer," which makes no sense. It's like saying "I don't like red-coloured drinks". There are lots and lots of different kinds of dark beers, and they all taste different. So you may find that you like many of them, or some of them, or, theoretically, none of them, but as long as you think that "dark beers" share more than just the colour, you are clearly not in a position to judge. ...

A quick introduction to CXTM

I got some questions about how CXTM actually works, so I thought I'd put together a little introduction to it. If you want to create a CXTM file for one of your own topic maps you can actually do this in Omnigator with the export plug-in. ...

An XTM conformance test suite

One thing that's really needed is a conformance test suite for XTM 2.0, which can be used by implementors to verify that they've actually gotten their implementations right. Of course, it could also be used by customers to verify that the implementation they are thinking of buying actually conforms to the standard. This is becoming more important as the hype around Topic Maps grows, and vendors start claiming they support Topic Maps without even knowing what it is. ...

How to write a TM/XML deserializer

The TM/XML syntax is easy to understand for humans, and easy to process with XSLT, but seeing how to write a TM/XML deserializer is not trivial from the spec. However, once you know how to do it it's actually quite straightforward, so I thought I'd document the approach that I took here in case anyone else wants to have a go at this. ...

TMRA'06 program published

The program for TMRA'06 has now been officially published. This year we have 32 talks, up from 24 last year, and I think this year's program is substantially stronger than last year's. It's interesting to note that quite a few of last year's open space entrants reappear this year as full-blown presentations. This year there is also a day of tutorials, so the conference is definitely grown compared to last year. ...

Россйя

For this year's holiday we plan to fly to Moscow, then travel south to Kiev, and on from there to the Crimea, and finally back to Moscow for the return flight. The tickets are already bought, and we leave on August 25. However, our Russian experience has already started. I'm not referring to the Russian language course that we've started, but the hotel booking and visa application. ...
