What Hath Woz Wrought (1979)

An old mentor once said &quot;Don&#x27;t solve things in software that should be solved in hardware.&quot;<p>Unfortunately, adding a clock to the thermal element was a software solution masquerading as a hardware solution. If you have a piece of your system that can start a fire, you need to be sensing temperature, somehow. Sensing anything else is daring reality to get creative with your abstraction model.

Good reminder to monitor for the actual problem, and not a proxy, if you can.<p>Printer heads being on for 10ms isn&#x27;t a problem, overheating is. Might have been cost-prohibitive or too complex to add in a thermometer and use that to shut down in addition to the 10ms test, but in a perfect world..
