John McLaughlin – Ronnie Scotts London July 2011

03/08/2011

A bit late, due to holidays, but too good not to report. I saw the guitar legend and his band the 4th dimension at Ronnie Scott’s in London last month. Probably the most expensive tickets I have ever bought, but to be 10 feet from McLaughlin and the rest of the band … why not?

I won’t bother to try to describe his playing, you can find samples on youtube, but to give an idea, it was in the groove of a) his own music (of course) – louder and tighter than ever, b) reminiscent of Jeff Beck / Jan Hammer in the 80s and c) some sensibilities of Jan Akkerman, the great Dutch Jazz guitarist. McLaughlin goes further and harder than you expect – he plays great jazz lines over hard syncopated rock rhythms.

Gary Husband played keyboards, and as ever, is a great personality in stage. You never know quite what he is going to do. This gig, he left the keyboard for a while and went head to head in a drum duel with Ranjit Barot for around 10 minutes. The presence of two complete drumkits on the stage was a warning that something amusing was likely to happen. It was like the ‘cuttin’ heads’ scene in the Crossroads movie, but with humour. Translated into words… Barot: I’m the real guy here, cop this… Husband: wimp. Take this. Barot: just getting my overcoat off here. Whack! Husband: that sucked, eat my sticks! Barot: off my stage, pretender! …. you get the idea. Etienne Mbappe on bass was just a joy to listen to (especially for me, he was 3 feet away), punching out hard rhythms, lots of slap and melody.

Summary: a bunch of world class musicians + 1 legend in London’s most famous jazz club = perfection.


Information models, DCMs and Archetypes

07/07/2011

I will be attending a ‘Fresh Look’ meeting in Washington next week. The idea is to make some progress on the topic of  ‘detailed clinical models’ (DCMs). Some of the goals include setting up a repository of DCMs, establishing governance, and defining a roadmap for tooling. Underlying all this is a huge list of formalisms and models, including OWL, UML, ADL, HL7 MIF, XSD, LRA, RMIMs, CDA templates, greenCDA and so on. Read the rest of this entry »


A reboot for Eiffel, the world’s best programming language?

03/07/2011

On 27 June, I ran a workshop at TOOLS 2011 in Zurich, entitled ‘Creating the new Eiffel Technology Community’. I did this at the invitation of Bertrand Meyer, the inventor of Eiffel and also the TOOLS conference programme chair.

DCMs – can they look good AND be computable?

08/06/2011

Let’s talk about mindmaps and archetypes. Mindmaps seem to be fuzzy and friendly – we need them because they are incredibly efficient at transmitting information to humans. Archetypes seem über-mathematical, but we need them to do proper model-based computing.

Detailed Clinical Models (DCMs) – some basic facts

03/06/2011

The New Zealand e-health programme architecture task-force has published its Working Interoperability Reference Architecture blueprint document. With respect to the document and the comments posted (I tried to post myself,  but the comment disappeared), it seems worth making a couple of points on DCMs, of whatever flavour. If a DCM is to be expressed in a way useful to building and managing health IT infrastructure, there are two possibilities. Read the rest of this entry »


Ontologies and information models: a uniting principle

24/05/2011

Software developers and ontologists generally live in two different worlds. The former group think they are building systems to perform information processing and computation, and the latter group think they are formally describing some aspect of the world.

The HL7 Null Flavor Debate – part 1

18/05/2011

(With apologies to those who use international English and normally spell it as ‘flavour’; in this post, I will spell it properly in informal text, and in the US way when referring to the formal HL7 null flavour concept.)

Grahame Grieve has pointed out in a recent blog post that I am a major critic of HL7 ‘null flavours’. This is correct, but the reasons are probably misunderstood, so I will try to clarify here. Read the rest of this entry »


One information model to rule them all?

05/05/2011

One of the age-old debates in health informatics: can there be ‘one information model’ for shared clinical information? Some dream of a model to rule them all, uniting standards efforts, while others dismiss the idea as impossible or unrealistic. Obviously inside deployed health/hospital information (and all other – lab, GP, nursing, billing, PAS etc) products, there are private, differing information models. These do not concern us.

Film review – Animal Kingdom ****

02/05/2011

This Australian film has much to recommend it. It maintains a dark, slow-burn tension for the duration, a by-product of characters who while being completely believable become less and less predictable as time goes on. In a way the film is a kind of trick: you are initially not sure if you are in for a gangster story (will there be a heist, or a gangland battle?), a psycho-drama, or a character study.
