Soaked

Although I stopped working on the client's problem at 02:00, with one mystery unresolved, I soon got to the bottom of it after being woken by the guys arriving to work on  the kitchen. It was good to be able to tell the client that our solver was 400 times faster than the one he was using! After that, it was back to coding until I nipped out to get some more milk - just as the rain came on hard! 

A dull day weather-wise seemed duller due to being tired!
