You are using Continuous Integration, aren't you?

This is one of those questions expecting the answer yes, like you have lost your virginity, haven't you?, which has a motivational impact.

Another prod in the right direction was when someone used Hudson as the term for CI server, as you would use Hoover for vaccum cleaner.

I have tried three times to use Continuum, only once with any degree of success. Hudson just works, straight out of the box.

I am proud to say I am, at last and later than most, using Continuous Integration.

The map is not the territory

My new job on the Erewhon Project is largely based upon the work of my predecessor Arno Mittelbach.

In a series of posts leading up to the new OxPoints Arno rediscovers the issues around using first order predicate calculus on continuous dimensions such as time.

This would appear to be a rediscovery of the Yale Shooting Problem: the real world cannot be modelled in a monotonic logic. Locations are not points but areas, names are not simple properties but have implicit usage start and end times. Only in maths is something as simple as its description: the map is not the territory.

amd64 "no such file or directory" error with Android and Skype

Using an amd64 debian (lenny and kubuntu jaunty) install I came across the least informative error message yet:

bash: adb: No such file or directory

and similarly for skype.

This appears to be due to not yet having installed the i36 compatibility libraries:
apt-get install ia32-libs
and it goes away.

Bye then Pepper. Good girl.


On Wednesday morning, at about 8.15, Pepper died.

Whilst she was rather young (eleven maybe) to die, for a mongrel, her timing was pretty good. It was the first day of my new job and as it was all of us were stroking her as she stopped breathing, twitched and was gone.

Pictures tell of thousands of words

Had to give a presentation for an interview with OUCS on "the challenges of creating mobile location-based services to students" so took a walk and photographed the signage.

Did the presentation in OpenOffice Impress, but of course the fonts were different on Windows and the colours were the first ones I chose not the ones I had settled on and saved and which showed on Apple and Linux.
If I don't get the job I will blame grotty software.

Wavemaker 32 bit rpm on amd64 debian

As there is no appropriate .deb file for wavemaker but the rpm is pure java so the following works:

rpm2cpio wavemaker-4.0.2.24308-community.i386.rpm >wm.cpio  
cpio -idv  < wm.cpio

mv opt/wavemaker-4.0.2.24308 /opt/   /opt/wavemaker-4.0.2.24308/bin/wavemaker.sh
