Thank you very much Andrew, I won't ever forget our talks at your house in Buitenveldert/Amstelveen they came at a very important point in my life and made a positive and lasting impact. You were amazingly accessible even to 'outsiders'. I regret never to have been able to study at the VU, I'd have happily done so. One thing you did is to instill a life-long habit of looking at the world as an asynchronous hard real time affair and to appreciate micro-kernels as a very elegant solution to a lot of problems.
