  • That’s generally true for most HVAC applications. Bang-bang control creates limit cycle behaviour and as long as a small oscillation in temperature is acceptable, it’s a nice simple solution.

    OPs problem seems to be a discontinuity between the two limit cycles, heating and cooling. The way to tackle this is to make time series vectors of all measurements and compare them with the subjective sensation of the room temperature. That should inform the relevant set points for the control actions.




  • How is this even a question? If you believe someone is good and they decided to do something against the law but for good reasons, are you going to punish that person? We know rules are important in society and we all aspire to be good citizens but sometimes we find ourselves in situations where we have to abandon our principles or break the law. Nobody is obeying the speed limit when carrying a dying child to hospital and nobody is condemning that person for breaking the law, to give a completely fatuous example.

    The reason jurys convict ethically sound defendants is the same reason people fail to make the ethically sound choice in the Milgram experiment.

    It doesn’t matter what the legal statutes say, you still have to think for yourself and others to make compassionate choices.








  • The situation where a candidate is rejected because they don’t have relevant experience is often decided by people who don’t have that experience either. The last thing I want is a job where I immediately know how to do it. That’s often the reason to leave - it’s boring and not a challenge any more.

    The market is probably flat right now and that’s the reason there’s no jobs. You have to hang in there for a bit and wait for an upturn.






  • 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.
