  • I feel blessed that I like my current job. Good manager, interesting work, limited amounts of bureaucracy. Most of this is a lucky coincidence but there are some things we can do. I had to explain many times to people which tasks I’m good at and which ones they should ask other people to do. I regularly defend this position. I set aside the morning for creative work only, no meetings, no admin, just thinking and solving. In the afternoon I down tools and do something physical, outside in daylight. A regular sleep cycle is absolutely critical for the maintenance of health and mood. Fresh food and companionship. Regular meditation. Do the basics well. These are the things that have made me happy.

















  • Vehicle control systems are overwhelmingly programmed in C, mostly from graphical design tools such as MATLAB Simulink via an automatic process. These are real time control systems which are quite different to an interrupt based operating system such as Linux. The many individual controllers must work in concert according to a strict architecture definition and timing schedule that defines the functionality of the vehicle. It’s not at all like a PC or phone, whose OS become irrelevant over time, with respect to their environment of other systems. The vehicle environment is the same environment that we inhabit i.e. the one with gravity, friction, charge and the other SI units. This is slowly changing with advent of self driving but, yeah.
